Abstract
The invention relates to a piston push centrifuge, in particular to improvement of single-stage piston push centrifuge and rotary drum combination way. The right end of a wheel disc is connected with a cylinder body of the rotary drum by using a screw, the left end of the wheel disc is connected with a hollow main shaft, a push disc is connected at the right end part of a push shaft, the push shaft penetrates the wheel disc and is arranged in an inner hole of the main shaft through a sliding bearing, and a plurality of adjustable push pieces are mounted on the outer circumference of the right end surface of the push disc. The inner diameter on the left side of the cylinder body of the rotary drum is in interference fit with the outer diameter of a boss of the wheel disc; and the maximum deformation of the rotary drum is reduced from being larger than or equivalent to 0.5mm to being below 0.20mm after changing the inner diameter on the left side of the cylinder body of the rotary drum to be in interference fit with the outer diameter of the boss of the wheel disc, thereby not only improving the dehydration rate of the centrifuge by 1% to 2%, but also leading the operation to be more stable.
Description
Technical field
The present invention relates to piston material pushing formula centrifuge, be specifically related to single stage piston push-type centrifuge rotary drum combining structure.
Background technology
Piston material pushing formula centrifuge is a kind of perforated wall centrifuge, as its name suggests, piston material pushing formula centrifuge is the mechanism that adopts a kind of similar piston in rotary drum, the filter cake that is trapped on the rotary drum screen cloth is progressively released rotary drum, realize the discharging of centrifuge, the mechanism of this similar piston can be that pusher dish (for example single stage piston pusher centrifuge) also may be prime rotary drum (multistage pusher centrifuge).The cake moisture of removal rotary drum is as far as possible low to be the basic demand that centrifuge separates; The cake layer that forms even thickness, surfacing in the rotary drum is the prerequisite of the normal operation of centrifuge.For the ease of processing and maintenance, at present the piston push centrifuge rotary drum generally adopts combined type, the rotary drum that the discoid wheel disc that is namely connected by screw and rotary drum body cylindraceous form piston push centrifuge.At present, matching relationship between piston material pushing formula bowl cylindrical shell and wheel disc is matched in clearance, when centrifuge turns round, filter cake in the rotary drum and the huge centrifugal force of the mass formation of rotary drum own, bear by rotary drum body, rotary drum body is as a thin-wall circular cylindrical shell, unavoidably can produce distortion, and be out of shape irregularly, maximum deformation quantity can be more than or equal to 0.5mm, minimum place even jam pusher dish, in order to make the normal pusher of pusher dish, only turn the diameter of pushing sheet down, the total backlash between wheel disc and the screen cloth is strengthened, so the pusher dish is difficult to push away the filter cake on the clean screen cloth, this remaining cake layer becomes dense through the extruding of pusher dish, even stop up the screen cloth gap, and make newborn cake dewatering insufficient, water content increases suddenly; Inhomogeneous, the surface irregularity of cake layer that forms on the other hand adds the rotary drum body distortion, and the rotary drum running is uneven, must make centrifuge vibration aggravation.
Summary of the invention
The object of the invention is to solve above-mentioned deficiency, the form of the reasonable coordination between a kind of rotary drum body and the wheel disc is provided.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the wheel disc right-hand member is connected with screw with rotary drum body, the wheel disc left end is connected with hollow main shaft, the pusher dish is connected to the pusher shaft right part, pusher shaft runs through wheel disc and is contained in the inner hole of spindle by sliding bearing, pusher dish right side excircle is equipped with some adjustable pushing sheets, is interference fit between rotary drum body left side internal diameter and the wheel disc boss external diameter.
Further technical scheme is:
The magnitude of interference between described rotary drum body left side internal diameter and the wheel disc boss external diameter is 0.07mm to 0.10mm.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is with after changing interference fit between rotary drum body and the wheel disc, the rotary drum body maximum deformation quantity is by reducing to below the 0.20mm more than or equal to 0.5mm, and dehydration rate improves 1% to 2%, and the centrifuge smooth running.

Fig. 2 is the local enlarged diagram in A place of Fig. 1.
The specific embodiment
The present invention is further elaborated below in conjunction with accompanying drawing.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of piston material pushing formula bowl combining structure, comprise that wheel disc 4 right-hand members are connected with rotary drum body 6 usefulness screws 8, wheel disc 4 left ends are connected with hollow main shaft 1, pusher dish 5 is connected to pusher shaft 3 right parts, pusher shaft 3 runs through wheel disc 4 and is contained in main shaft 1 endoporus by sliding bearing 2, and pusher dish 5 right side excircles are equipped with some adjustable pushing sheets 9; Be interference fit between rotary drum body 6 left side internal diameters and the wheel disc 4 boss external diameters, the magnitude of interference is 0.08mm.
Embodiment 2: as shown in Figure 1 and Figure 2, a kind of piston material pushing formula bowl combining structure, comprise that wheel disc 4 right-hand members are connected with rotary drum body 6 usefulness screws 8, wheel disc 4 left ends are connected with hollow main shaft 1, pusher dish 5 is connected to pusher shaft 3 right parts, pusher shaft 3 runs through wheel disc 4 and is contained in main shaft 1 endoporus by sliding bearing 2, and pusher dish 5 right side excircles are equipped with some adjustable pushing sheets 9; Be interference fit between rotary drum body 6 left side internal diameters and the wheel disc 4 boss external diameters, the magnitude of interference is 0.10mm.
The application of the fit form between rotary drum body of the present invention and the wheel disc is not limited to the single stage piston pusher centrifuge in the present embodiment, and is applicable equally in secondary of the same type, three grades and multi-level piston pusher centrifuge.
