Description

Mix machine convenient to degree of consistency control

Technical Field

The invention relates to the field of float glass processing, in particular to a mixer convenient for uniformity control.

Background

In the float glass processing process, a plurality of glass raw materials are required to be put into a forced mixer for mixing and then used, and the uniformity of the raw material mixing is very important to the final quality of the glass, so that the uniformity of the mixed material needs to be strictly controlled. In the field, the mean square error is generally evaluated by a method of measuring and calculating the mean square error and is required to be stable and less than or equal to 0.30, but for most manufacturers, the mean square error can only be ensured to be 0.25-0.40 in most cases, and the value is fluctuated, so that the mean square error cannot be ensured to be stable and less than or equal to 0.30 at all.

What causes mean square error instability? How to stabilize the mean square error of the mix? Manufacturers in this area are seeking reasons for various improvements, such as: 1. adjusting the blanking sequence of various raw materials to ensure that the blanking reaches sandwich type distribution so as to be convenient for mixing; 2. adjusting the coefficient of the mixed filling; 3. adjusting the time of dry mixing and wet mixing in the mixing process; through the above series of measures, the fluctuation of the mean square error tends to decrease, but the problem is not completely solved.

Therefore, the manufacturer continues to search for the reason, and after a series of other tests, the quality of the bottom plate of the mixer, which is a factor ignored in the industry, is found to have an important influence on the mixing uniformity. Since in the prior art, a PE wear plate is mostly used as the bottom plate. The PE material is polyethylene, namely polyethylene, so the PE material is short for PE, feels like wax, has good chemical stability, excellent low-temperature resistance, can resist corrosion of most of acid and alkali, is insoluble in common solvents at normal temperature, and has small water absorption and excellent electrical insulation. Especially, the existing high molecular polyethylene plate has the advantages of good wear resistance, impact resistance, chemical corrosion resistance, self-lubrication, extremely low hygroscopicity, no toxicity and other properties, extremely high wear resistance which is 4 times higher than nylon 66 and polytetrafluoroethylene and 6 times higher than carbon steel, and the chemical stability of the plate is very high in all the prior synthetic resins named as pioneer cogongrass. Because the PE material has the advantages, the PE wear-resistant plate is adopted by the base plates of most of mixing machines, but after deep analysis of the wear-resistant base plates, the friction coefficient among materials is reduced due to the good smoothness and self-lubrication of the wear-resistant base plates, so that the shearing mixing degree among the materials is insufficient during mixing, and the mixing uniformity is unstable; meanwhile, in various experimental analyses on the bottom plate, the distance between the bottom plate and the shovel blade is found to cause unstable mixing uniformity, and the proper distance is also an important influence factor influencing the mean square error.

Therefore, manufacturers replace the PE wear-resisting plate with a bottom plate made of other materials, and simultaneously adjust the distance between the bottom plate and the shovel blade so as to stabilize the mean square error within a safety range of less than or equal to 0.30. However, the selection of specific bottom plate materials and related attribute parameters and the damage speed of the bottom plate caused by the replacement of the bottom plate materials are increased, so that new problems such as frequent replacement of the bottom plate and the like are caused, and meanwhile, the replacement difficulty is increased due to the large and heavy size of the mixing machine, and the new problems need to be solved.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 7, the present invention provides a mixer for facilitating uniformity control, which includes a base 100, a cover 200, a stirring mechanism 300, and a wear-resistant sub-plate 400 for mixing raw materials for float glass processing.

In particular, the base 100 is used to support other components. The cover body 200 covers the base 100, a feed inlet 210 is formed at the top of the cover body 200, and a discharge outlet 220 is formed on the side wall of the cover body 200. The inlet 210 is for feed and the outlet 220 is for discharge. In a specific implementation, a lifting lug 230 may be provided on the exterior of the shroud 200, and when the wear-resistant sub-plate 400 is replaced, the shroud 200 may be lifted by the lifting lug 230 for replacement.

The stirring mechanism 300 is used to stir the glass raw material. The stirring mechanism 300 includes a driving assembly 310 and a stirring part 320. The driving assembly 310 is disposed within the base 100. The stirring section 320 includes a stirring rod 321 and a shovel blade 322. The stirring rod 321 is disposed on the driving assembly 310 and penetrates into the cover 200, the plurality of shoveling sheets 322 are provided, and the plurality of shoveling sheets 322 are uniformly disposed along the radial direction of the cover 200.

A wear sub-plate 400 is provided on the top surface of the base 100 and within the enclosure 200. The wear-resistant subplate 400 comprises a plurality of fan-shaped plate lobes 410. The plurality of plate flaps 410 can surround to form a circular ring-shaped plate with a through hole 420 at the center, and the through hole 420 is tightly embraced at the root of the stirring rod 321. In specific implementation, a bearing or other rotatably connected components may be disposed outside the stirring rod 321, and the plurality of plate flaps 410 may be tightly held on the bearing, so as to facilitate rotation of the stirring rod 321.

The forming method of the wear-resistant sub-plate 400 is mainly die forming or machining forming, for example, in the prior art, the forming of the PE wear-resistant plate basically adopts hot press forming, and belongs to one of die forming, and the parameter value range of the surface roughness Ra after the material forming can basically reach below 3.2 μm no matter the die is injection molding or extrusion molding, and the surface quality shown reaches a smooth surface or at least a higher semi-smooth surface effect. If other resin materials or metal materials are used for forming by machining, the parameter value range of the obtained surface roughness Ra is generally 3.2-6.3 mu m even if the common fine machining equipment is used, and the visible part of the machining trace on the surface belongs to a semi-smooth surface; a machined surface of Ra6.3 μm or more (surface roughness after 6.3 results in a grade of Ra12.5 μm) is slightly marked with tool marks, and belongs to the category of primary machining. Furthermore, the surface roughness of the wear-resistant sub-plate 400 should be larger than Ra3.2 μm in this scheme, based on the fact that the surface roughness needs to be larger than that of the existing PE wear-resistant plate. When the method is specifically implemented, the optimal Ra6.3 mu m is selected, the surface quality of the bottom plate at the grade can meet the requirement of mutual shearing on the roughness of the surface during material mixing, and the condition of surface material adhesion can be better avoided. The wear-resistant auxiliary plate 400 is made of a specific material, such as an iron plate, a steel plate and other metal plates, and the material and machining cost is low.

When in use, the raw materials are poured in from the inlet 210, stirred by the stirring mechanism 300 and then flow out from the outlet 220. After long-time use, because of the motion friction of the material on the surface of the wear-resistant subplate 400, the surface of the wear-resistant subplate 400 becomes smoother due to wear, along with the aggravation of wear, when the friction coefficient of the wear-resistant subplate 400 is found to be seriously reduced and needs to be replaced, the cover body 200 is firstly lifted, the plurality of plate petals 410 are simultaneously and respectively pulled out along the radial direction outwards, and then the new plate petals 410 are simultaneously and respectively inserted along the radial direction inwards, so that the replacement of the wear-resistant subplate 400 can be rapidly completed, and then the cover body 200 is put down and is placed on the wear-resistant subplate 400.

Adopt a plurality of fan-shaped lamella 410, can adopt the mode that the level was inserted, assemble into wear-resisting subplate 400 with a plurality of lamella 410, then can be smooth keep away the rabbling mechanism 300 device to reduce the distance that cover body 200 hung high, and then improve the security. When the friction coefficient of the wear-resistant auxiliary plate 400 is found to be seriously reduced, the wear-resistant auxiliary plate can be quickly replaced, and finally the aim of controlling the uniformity and enabling the mean square error to be in a complete range is fulfilled.

In this embodiment, in two adjacent plate flaps 410, a sliding groove 412 communicating with the outside is formed along a radial direction of an end surface of one plate flap 410 facing the other plate flap 410, a protruding strip 411 adapted to the sliding groove 412 is formed on an end surface of the other plate flap 410, and the protruding strip 411 is slidably engaged in the sliding groove 412. By adopting the manner of clamping the convex strips 411 and the sliding grooves 412, all the plate petals 410 can be quickly spliced in place, and meanwhile, the stability of the whole wear-resistant auxiliary plate 400 is also improved.

As a preferred embodiment, the outward side of the plate flap 410 is provided with a cuff 413 extending upward. The outer side surface of the flange 413 can tightly abut against the inner wall of the cover body 200. In the use, a plurality of turn-ups 413 can form circumference external pressure to the inner wall of the cover body 200, prevents at the hybrid process, and the cover body 200 off tracking because of vibrations, certainly, when concrete implementation, can also set up the groove at the top of the lateral surface of turn-ups 413, and certain guide effect can be played to the groove to make the quick centering of cover body 200 in the placement process.

To prevent fine material from being introduced into the joint between the plate flap 410 and the plate flap 410, the wear-resistant subplate 400 further includes a plurality of seals 430. Each flap 410 is movably connected with a seal 430 along one radial edge, and the seal 430 can cover the seam formed by splicing the two flaps 410. The movable connection mode can adopt hinge joint and clamping joint. If clamping is adopted, a clamping groove is formed in the plate flap 410, a buckle is arranged on the seal 430, and after the wear-resistant auxiliary plate 400 is enclosed, the seal 430 is clamped and the joint is covered.

In the present embodiment, the seal 430 includes a pressing portion 431 and a supporting portion 433. The pressing portion 431 has a long bar shape, and the bottom surface of the pressing portion 431 is a pressing surface 432. One edge of the compression surface 432 is hingedly connected to one of the petals 410. The supporting portion 433 is a long elastic strip. One long side of the supporting portion 433 is connected to the edge of the pressing portion 431, the other long side of the supporting portion 433 extends obliquely to the direction of the connected petals 410 until the supporting portion 433 abuts against the petals 410, and the included angle between the supporting portion 433 and the pressing surface 432 is less than 180 degrees.

When the two flaps 410 are closed, the pressing surface 432 of the pressing portion 431 of the seal 430 is located on the adjacent flap 410, and because the included angle between the supporting portion 433 and the pressing surface 432 is less than 180, the edge of the supporting portion 433 can be pressed against the end surface of the adjacent flap 410, so that the two sides of the whole seal 430 and the two flaps 410 form a pressing sealing state to cover the seam, and the thin material is prevented from falling into the seam. Simultaneously, in the stirring mixing process, can also form in the rotatory tangential direction of material and block the effect, further improve the mixed effect.

In addition, when the method is implemented again, the top of the whole seal 430 may be set to be circular arc, that is, the cross section of the seal 430 is fan-shaped, so that dead corners formed by the seal 430 are avoided, and thus, part of the material is clamped into the dead corners and cannot participate in mixing, thereby affecting the quality of the product.

The mixer also includes an adjustment mechanism 500. The adjusting mechanism 500 is disposed between the wear-resistant sub-plate 400 and the base 100, and is configured to support the wear-resistant sub-plate 400 and adjust a distance between the wear-resistant sub-plate 400 and the shovel blade 322.

Specifically, the adjustment mechanism 500 includes a fluid source 510, a plurality of connecting tubes 520, and a plurality of balloons 530. The fluid source 510 is disposed outside the cover 200, and the fluid may be gas, liquid, etc., and preferably liquid phase fluid with poor compressibility, so as to reduce the amount of compression deformation under pressure and improve the stability of the support by the airbag. Correspondingly, the fluid source 510 may be an air pump, a water pump, or any other device capable of providing the fluid source 510. One end of each of the plurality of connection pipes 520 is connected to the fluid source 510 in parallel, the other end of each of the plurality of connection pipes 520 extends from the base 100 into the housing 200 and is connected to an air bag 530, and an air bag 530 is disposed under each of the plurality of plate petals 410.

In a parallel manner, the air bags 530 can be inflated simultaneously, so that all the flaps 410 can be lifted simultaneously, and the stability of the whole abrasion-resistant subplate 400 in the lifting process can be increased. The mean square error can be further varied by adjusting the distance between the wear-resistant secondary plate 400 and the shoveling blades 322 during the mixing process.

Experiments prove that: adopting a wear-resistant auxiliary plate 400 with the roughness larger than Ra3.2 mu m, adjusting the clearance between each shovel piece 322 and the wear-resistant auxiliary plate 400 to be less than 8mm according to the requirements of a raw material workshop, carrying out trial batching under the condition of continuing using original mixing parameters, and carrying out sampling detection, wherein the mean square error is 0.29, the sampling detection is carried out again after 1 day of trial use, the mean square error is stable to be less than 0.30, and the sampling detection is carried out again after 1 week of continuous use, and the mean square error is still stable to be less than 0.30; and then, a plurality of mixers are modified in the same way, and the mixture is used till now, and is sampled and detected for a plurality of times in the period, so that the uniformity of the mixture is always stabilized below 0.30, and the industrial standard of float glass production is reached. It can be proved that the most mean square error is stable when the gap between the shovel blade 322 and the wear-resistant auxiliary plate 400 is adjusted to be less than 8 mm. The particular height is determined by the particular amount of fluid that is inflated into the bladder 530.

Meanwhile, experiments also prove that in the fluid, the liquid has better effect than the gas, and in the liquid, the high-density liquid has the best effect, such as the liquid mercury has the relatively best stabilizing effect.

In this embodiment, the pressure equalization of the fluid is divided into four stages:

first stage, filling stage:

in the initial state, the sum of the gas injected into the bladder 530 is calculated by adjusting the height of the wear-resistant sub-plate 400 as necessary and adding the capacities of the inner cavity of the inner vessel 5411 and the accommodation cavity 5416. At this time, as shown in fig. 5, the first communication hole 5413, the second communication hole 5414 and the third communication hole 5415 are all in an open state, the fluid in the fluid source 510 flows into the inner cavity of the inner tank 5411 through the first communication hole 5413 first, at the same time, the gas in the inner cavity of the inner tank 5411 flows into the accommodating chamber 5416 through the second communication hole 5414, flows into the parallel pipe 543 through the third communication hole 5415, and flows into the plurality of balloons 530 through the parallel pipe 543 simultaneously, when the total amount of injected gas reaches a calculated amount, the handle 544 is rotated clockwise by 40 ° to switch to the state shown in fig. 6, so that the sealing end 5421 blocks the first communication hole 5413, and the gas is prevented from being injected continuously;

the second stage, the preliminary balancing stage:

referring to fig. 6, at this stage, after the first communication hole 5413 is blocked, gas injection is stopped, the accommodating chamber 5416, the inner tank 5411 and all the airbags 530 are in a communication state, the liquid in the airbags 530 balances the fluid in the accommodating chamber 5416 and the inner tank 5411 through the accommodating chamber 5416 and the inner tank 5411, and the accommodating chamber 5416 and the inner tank 5411 play a role in balancing excessive fluid, so that the pressure generated by the fluid in the airbags 530 is initially balanced, and the pressure of the gas in the airbags 530 is P1;

third stage, equilibrium stage again:

after the preliminary balancing stage, the handle 544 is rotated clockwise by 40 ° again, so that the sealing end 5421 blocks and closes the first communication hole 5413 and the second communication hole 5414 simultaneously, and the state is switched to the state shown in fig. 7, at this time, the space between the air bags 530 and the inner cavity of the inner tank 5411 are in the communication state, fluid can flow between the air bags 530 and the inner cavity of the inner tank 5411 once again, the pressure difference is balanced again, the balance stability of the wear-resistant sub-plate 400 is improved again, and at this time, the pressure of the gas in the air bags 530 becomes P2;

fourth stage, final stabilization stage:

after the second balancing stage, the on-off valves 521 on all the connecting pipes 520 are closed, and the connections between all the air bags 530 are cut off, so that the air pressure in the air bags 530 finally becomes P3 and keeps unchanged, the air bags 530 reach the final balance, and the stability of the wear-resistant sub-plate 400 is finally ensured.
