Description

Technical Field

[0001] This application belongs to the technical field of garbage treatment, and particularly relates to an anti-winding screw pump for garbage transportation. Background Art

[0002] During the treatment process in a garbage treatment station, a crusher is generally used to roughly process the garbage, which is then conveyed to a briquetting machine by a conveyor belt for briquetting, and then transported to a landfill by a sealed transport vehicle.

[0003] During the conveyor belt transportation, since the water content of the garbage is generally high, it is easy to slide on the conveyor belt, and a screw pump is needed to convey it back to the conveyor belt.

[0004] In related technologies, the screw pump used is usually an ordinary screw-type screw pump. However, since items such as plastics and woven belts commonly present in garbage are easily wound around the end of the screw during rotation, the discharge port of the screw pump is easily blocked.

[0005] Therefore, it is necessary to provide an anti-winding screw pump for garbage transportation to solve the problems raised in the above background art. Summary of the Invention

[0006] This application provides an anti-winding screw pump for garbage transportation. Aiming at the problem that items such as plastics and woven belts are easily wound around the end of the screw in the prior art, a cutter is provided at the end of the screw to cut the wound plastics, woven belts and other items into small pieces, making it easy to discharge through the discharge port and not easily causing blockage of the discharge port of the screw pump.

[0007] To solve the above technical problems, the technical solution of this application lies in:

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] Please refer to Figures 1-3 , the present application provides a garbage conveying anti-twisting screw pump 100, including a housing 10, a screw rod 20 and a cutter 30.

[0027] Both ends of the housing 10 are closed, and an accommodation space is formed inside. A feed inlet 11 and a discharge outlet 12 communicating with the accommodation space are respectively arranged on the side walls near both ends.

[0028] In the actual practical process, since the garbage that has fallen to the ground needs to be re-conveyed to the conveyor belt, therefore, the whole screw pump 100 is placed obliquely, so that the feed inlet 11 is kept at a low position and the discharge outlet 2 is kept at a high position.

[0029] The screw rod 20 is installed in the housing 10. The screw rod 20 and the housing 10 cooperate to form a spiral flow channel 40. The screw rod 20 can rotate around its own axis to drive the garbage to move from the feed inlet 11 to the discharge outlet 12 in the flow channel 40.

[0030] Specifically, the screw rod 20 includes a rotating shaft 21 and a spiral plate 22. Both ends of the rotating shaft 21 are fixed to the housing 10 through bearings. One end of the rotating shaft 21 passes through the end of the housing 10 and is connected to a driving motor, and is driven to rotate by the driving motor. The spiral plate 22 is spirally wound around the periphery of the rotating shaft 21. When the rotating shaft 21 rotates, the spiral plate 22 rotates synchronously to apply a driving force to the garbage in the flow channel 40.

[0031] One end of the cutter 30 is fixed to the housing 10, and the other end is arranged at an interval at the end of the spiral plate 22. During the rotation of the screw rod 20, as the screw rod 20 rotates, the garbage at the end of the flow channel 40 presses against the cutter 30 and forms a relative movement with the cutter 30. The cutter 30 cuts the garbage into small fragments. Especially for some easily entangled objects such as plastics and woven belts, after being cut off, they can easily be discharged from the discharge outlet 12 along the flow channel 40 to avoid blockage.

[0032] The cutter 30 includes a fixing part 31 and a blade 32. The fixing part 31 is fixed to the inner wall of the housing 10, and the fixing method can be selected as bolt fixing. The blade 32 is connected to the fixing part 31 and is suspended at the end of the spiral plate 22. The blade 32 is inclined relative to the fixing part 31, and the blade 32 is inclined towards the screw rod 21 and is close to the screw rod 21, which restricts the passage of garbage. All the garbage conveyed to the end of the flow channel 40 passes through the blade 32 for cutting and then is discharged through the discharge port 12.

[0033] Specifically, the cutter 30 is of an annular structure, which can achieve a cutting effect in all directions.

[0034] The cutting edge of the blade 32 is located on the side facing the screw rod 21. A plurality of spikes 33 are arranged side by side on the inclined blade surface of the cutter 30. In addition to the cutting edge being able to cut garbage, the spikes 33 can also play a good role in scratching, further improving the cutting efficiency of easily entangled objects such as plastics and woven belts. At the same time, the inclined blade surface can also maintain a large contact area with the garbage, improving the cutting effect.

[0035] Preferably, the fixing part 31 and the blade 32 are integrally formed, which can maintain the structural stability.

[0036] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
