Description

Dispersing type winnowing machine

Technical Field

The invention relates to the technical field of environmental protection equipment, in particular to a dispersion type winnowing machine.

Background

In the modern city development process, the generation of various solid waste is unavoidable, and under the high requirement of advocating sustainable cycle reproduction, the search for a better treatment method is a new requirement on the industrialized route.

With the increasing level of living, various kinds of garbage in daily life are increasing, and some recyclable materials are generally included, such as plastic bags, metal bottle caps, packaging cartons and the like. If the garbage is not screened, the garbage in life cannot be effectively treated by any method, and obviously, the more refined the screening of the household garbage is, the higher the recycling degree of the renewable matters from the household garbage is.

There are two measures currently adopted for refining and screening household garbage: firstly, arranging a plurality of garbage recycling bins in town communities to require people to put household garbage in a classified manner, wherein the method has great implementation difficulty to improve the environmental protection consciousness of social personnel; secondly, before the advanced treatment of the household garbage, the household garbage is firstly sorted manually, so that the labor intensity is high, the production environment is bad, and the household garbage is difficult to sort thoroughly.

Winnowing machines have become increasingly the basic equipment for the treatment of kitchen waste, construction waste and other light and heavy material sorting processes in the field. For example, CN112676157a discloses a garbage winnowing device, wherein light and heavy materials are conveyed by a second conveyor belt to above a conical hopper and fall down, and heavy materials fall on a third conveyor belt through the conical hopper and are conveyed out by the third conveyor belt; different blowing angles and air volumes are selected according to the sizes and densities of the light materials so as to blow up the light materials, and meanwhile, the roller rotates towards the settling chamber so as to drive the light materials to enter the settling chamber for settling; the dust-containing gas in the settling chamber firstly passes through a filter screen to filter out part of light materials, then dust and clean gas are separated by a cyclone separator, and the clean gas flows back to the centrifugal fan through a return air pipe for recycling; the air blowing angle is adjusted in such a way that the motor drives the connecting shaft to rotate through the main bevel gear and the auxiliary bevel gear, and the connecting shaft drives the air blowing nozzle to rotate by a certain angle through the connecting plate.

The garbage winnowing equipment has the following problems:

(1) After the light and heavy materials are output from the second conveyor belt, the light and heavy materials are separated from the components in the equipment only through the wind force of the blowing nozzle, and because a space exists between the second conveyor belt and the roller, the light and heavy materials cannot be completely separated through the wind force of the blowing nozzle, namely, a part of the light materials still fall into the conical hopper, so that the separation efficiency of the light and heavy materials is low.

(2) The regulation of angle of blowing is motor drive master bevel gear and from the bevel gear drive connecting axle rotation, and the connecting axle passes through the connecting plate and drives the mouth rotation certain angle of blowing, and this kind of structural relation leads to the mouth of blowing to accomplish the action of rotation only, and in the in-service use, the material is diversified, because different materials need different wind-force values to reach the separation effect that degree needs, although the size of output wind-force is adjustable, this kind of adjustment is single, and the interval between mouth of blowing and the material cylinder can not be adjusted, thereby above-mentioned winnowing equipment can not decide the most preferred wind-force according to the condition of material.

(3) The winnowing feeding mode is as follows: the material output by the first conveyor belt directly falls on the second conveyor belt, and the defect of the mode is that the material is directly fed onto the second conveyor belt without being dispersed, so that the material is easy to form partial accumulation, and when the material is output from the second conveyor belt, the winnowing efficiency is low due to the reason of partial aggregation.

the first adjusting mechanism is used for adjusting the position of the belt conveying mechanism to enable the material output by the belt conveying mechanism to collide with the separating assembly, and is respectively connected with the shell and the belt conveying mechanism;

the flow direction of the blowing device output airflow is tangential to the peripheral surface of the separation assembly, when the material output from the belt conveying mechanism collides with the separation assembly, the light material moves along the peripheral direction of the separation assembly under the actions of airflow pushing and rotation of the separation assembly, and the heavy material after collision freely falls under the action of self gravity.

Through the first regulating mechanism in the technical scheme, the distance between the output end of the belt conveying mechanism and the material distributing roller in the separating assembly is controlled according to the requirement, after the material collides with the material distributing roller, the distance between the material and the material distributing roller is very close, even some materials are stuck on the surface of the material distributing roller, the flow direction of the air flow output by the air blowing device is tangential to the peripheral surface of the separating assembly, and the light materials move along with the material distributing roller under the common acting force of the air flow and the material distributing roller, so that the collision relation is not only used for separating the light materials and the heavy materials by the air flow blown by the air blowing nozzle, but also used for taking away the light materials by the common acting force of the air flow and the material distributing roller, thereby improving the separating effect and avoiding the light materials from falling into the material receiving box of the separating assembly. The invention is especially suitable for the winnowing of the construction waste.

In summary, the invention has the advantages that:

1. the success rate of material winnowing and sorting is improved, and the whole working speed of the production line is ensured.

2. The adaptability to different materials is expanded, and the influence of dust particles on the normal operation of equipment is reduced.

The inclined material receiving members 4 facilitate the dispersion of the material, since the material is dispersed around after collision with the material receiving members 4.

As shown in fig. 1 to 5, the material dispersing member 9 is disposed on the receiving surface d of the receiving member 4, for the material falling on the receiving surface d, the moving material is forced to be dispersed along the material dispersing member 9 due to the existence of the material dispersing member 9, so that the material is prevented from falling down on a certain position on the belt conveying mechanism C in a concentrated manner, and the air separation material falls on the belt conveying mechanism C in a dispersed manner, so that dust is removed on one hand, and the material on the belt conveying mechanism C is not in a stacked state on the other hand, thereby improving the uniformity of the transverse distribution of the material and the success rate of air separation.

The working process of the dispersion type feeding hopper A is as follows:

as shown in fig. 1 to 5, the former material enters the feed inlet 3, collides with the receiving part 4 by inertia and gravity, disperses the material during the collision, and the thick portion of the material flow center section formed by the characteristics of the belt conveyor is forcedly dispersed by the receiving surface d of the material dispersing part 9, and after being decelerated, uniformly falls onto the main plate surface e of the skirt 8, collides with the main plate surface e again to obtain dispersion, falls onto the belt conveying mechanism C after passing through the skirt 8, collides with the belt conveying mechanism C for the third time to obtain dispersion, and then enters the next flow.

As shown in fig. 1, 7 to 9, since one end of the swing arm 52 is hinged to the mounting seat 46, when the first driving assembly drives the other end of the swing arm 52 to rise or fall, the swing arm 52 is caused to perform a rotational movement, so that, on the one hand, the height of the air blast nozzle 51 mounted on the swing arm 52 is changed, and on the other hand, the angle of the air flow output of the air blast nozzle 51 is changed with respect to the distributing roller 47. Through the adjustment, when the distance between the air blowing nozzle 51 and the separation assembly D is adjusted through the first adjusting mechanism to change, the flow direction of the air flow output by the air blowing device E is tangential to the peripheral surface of the separation assembly D through the adjusting action of the second adjusting mechanism and the first driving assembly, so that the air separation efficiency is ensured.

In the present invention, as shown in fig. 1, 10 and 11, the material output from the belt conveyor C collides with the separating unit D by adjusting the position of the belt conveyor C by the first adjusting mechanism F, and in this embodiment, the collision of the material with the separating unit D is the fourth time, and the dispersion can be obtained as well. The first adjusting mechanism F is respectively connected with the shell B and the belt conveying mechanism C, the flow direction of the air flow output by the air blowing device E is tangential to the peripheral surface of the separation assembly D, when the material output from the belt conveying mechanism C collides with the separation assembly D, the light material moves along the circumferential direction of the separation assembly D under the actions of air flow pushing and rotation of the separation assembly D, and the heavy material after collision freely falls under the action of self gravity.

As shown in fig. 1, 10 and 11, the materials fall onto the belt conveying mechanism C after being dispersed by the dispersing type feeding hopper a, and are conveyed to the separating assembly D by the belt conveying mechanism C, and the light and heavy materials are required to be separated at the separating assembly D. In the present invention, after the position of the output end of the belt conveying mechanism C is adjusted by the first adjusting mechanism F, the material output from the belt conveying mechanism C collides with the distributing roller 47 in the separating unit D, and this relationship brings the following advantages:

(1) The distance between the output end of the belt conveying mechanism C and the material distributing roller 47 is controlled according to the requirement, after the material collides with the material distributing roller 47, the distance between the material and the material distributing roller 47 is very close, even if the material is stuck on the surface of the material distributing roller 47, the flow direction of the air flow output by the air blowing device E is tangential to the peripheral surface of the separating assembly D, and the light material moves along with the material distributing roller 47 under the common acting force of the air flow and the material distributing roller 47, so that the collision relation not only separates the light material and the heavy material by the air flow blown by the air blowing nozzle, but also takes away the light material by the common acting force of the air flow and the material distributing roller 47, thereby improving the separation effect and avoiding the light material from falling into the material receiving box 48.

(2) After collision, the potential energy of the heavy material is reduced, so that when the heavy material falls freely downwards, the initial speed of the heavy material is reduced, and the risk of crushing other parts is reduced.

(3) Since the position of the output end of the belt conveyor C is adjustable and the material output from the belt conveyor C collides with the distributing roller 47, it is avoided that the material output from the belt conveyor C falls directly on the blowing nozzle 51 to crush the blowing nozzle 51.

In the present invention, after the first adjusting mechanism F adjusts the belt conveying mechanism C, the position where the material output from the belt conveying mechanism C collides with the separating assembly D is the middle upper part of the separating assembly D, that is, the preferable collision position is located at the middle upper part of the separating roller 47, and after the collision occurs, the light material moves more easily along with the separating roller 47 due to the centrifugal force of the separating roller 47 and the acting force of the air flow, so that the air separation effect is better.

As shown in fig. 1, 10 and 11, when the first driving mechanism 61 is operated, the first driving mechanism 61 drives the belt conveying mechanism C to be lifted or lowered, thereby changing the height of the output end of the belt conveying mechanism C. When the second drive mechanism 62 is operated, the second drive mechanism 62 drives the belt conveyor C to move horizontally (the belt conveyor C is in sliding engagement with the inner frame 31 of the housing B), thereby changing the spacing between the output end of the belt conveyor C and the dispensing roller 47 in the separator assembly D. When the first driving mechanism 61 and the second driving mechanism 62 both have an adjusting action on the belt conveying mechanism C, the height, the horizontal position and the discharge angle of the output end of the belt conveying mechanism C can be changed. Therefore, by the action of the first regulating mechanism F, the collision of the material output from the belt conveying mechanism C with the distributing roller 47 can be ensured, thereby achieving the purpose of improving the air separation efficiency.
