Description

Technical Field

[0001] The utility model relates to the technical field of solid waste sorting, in particular to a multi-layer sorting device for solid waste treatment. Background Art

[0002] Solid waste mainly refers to the waste generated in industrial production and manufacturing as well as in daily life. According to the sources of waste generation, it is mainly divided into industrial solid waste, mining solid waste, urban solid waste, agricultural solid waste and radioactive solid waste. Since the sizes of solid waste are different, sorting work needs to be carried out before treatment.

[0003] The patent specification with the publication number of CN217450990U discloses a multi-layer sorting device for solid waste treatment, including a housing. The inner wall of the top end of the housing is fixedly communicated with a feed pipe. The bottom end of the feed pipe is fixedly communicated with a cleaning component. A sorting component is arranged below the cleaning component. The sorting component includes a first sorting component, a second sorting component and a crushing box. The first sorting component is arranged below the cleaning component. By setting the first filter box and the first filter plate, the waste can be initially screened. The large-sized waste is crushed through the arranged crushing box. Finally, the solid waste is divided into three types according to the size by the arranged second filter box and two groups of second filter plates. It can be seen from the above method that the utility model can maximize the screening of solid waste, and the accuracy of the screened solid waste is relatively high, which is convenient for subsequent workers to recycle the waste.

[0004] However, in the implementation of the related technology, it is found that the above-designed multi-layer sorting device for solid waste treatment has the following problems: In the prior art, screening is carried out through components such as the first filter plate. However, during the screening process, the waste is prone to accumulate and cause blockage, thus affecting the screening effect of the material. In view of this, a multi-layer sorting device for solid waste treatment is provided to overcome the above defects. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and a multi-layer sorting device for solid waste treatment is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: A multi-layer sorting device for solid waste treatment, including a screening cylinder. A feed port is opened at the top end of the screening cylinder. A guide hopper is fixed on one side of the feed port at the top end of the screening cylinder. A screening mechanism is arranged inside the feed port.

[0007] The screening mechanism includes a support plate, which is fixed inside the feed inlet. A motor is embedded above the support plate. The power output end of the motor is connected to a driving rod, and a pushing plate is fixed on the outer wall of the driving rod. A first filter plate is fixed inside the screening cylinder. When the material enters the screening cylinder, it is preliminarily filtered through the first filter plate to filter out larger waste.

[0008] As a further description of the above technical solution: The pushing plate is in close contact with the first filter plate, and the pushing plate and the first filter plate form a rotating structure through the driving rod. By rotating the pushing plate along the first filter plate, the filtered waste is pushed out of the screening cylinder.

[0009] As a further description of the above technical solution: A second filter plate is fixed below the first filter plate inside the screening cylinder. One end of the driving rod located inside the feed inlet is fixed with a stirring rod. Secondary filtration through the second filter plate facilitates multi-layer sorting. At the same time, the second filter plate is also provided with a pushing plate to facilitate pushing the filtered waste out of the screening cylinder.

[0010] As a further description of the above technical solution: A storage mechanism is arranged on the outer wall of the screening cylinder. The storage mechanism includes a storage shell, which is fixed on the outer wall of the screening cylinder. A first sliding shell is slidably connected inside the storage shell. A second sliding shell is slidably connected below the first sliding shell inside the storage shell. Anti-collision pads are arranged inside both the first sliding shell and the second sliding shell. The pushed-out waste enters the storage shell and is sorted and placed through the corresponding first sliding shell and second sliding shell to avoid mixing with each other again.

[0011] As a further description of the above technical solution: The storage mechanism further includes a receiving shell, which is slidably connected to the inner bottom end of the screening cylinder. A dust collection groove is opened inside the receiving shell. A supporting ring is fixed above the dust collection groove, and a fiber mesh is placed above the supporting ring. The receiving shell is used to store smaller waste and re-store the filtered smaller materials.

[0012] As a further description of the above technical solution: The second sliding shell and the storage shell form a sliding structure, and the second sliding shell is adhesively connected to the anti-collision pad. The first sliding shell and the second sliding shell are convenient for sliding out of the storage shell to collect the sorted waste. At the same time, the anti-collision pad avoids noise caused by knocking.

[0013] As a further description of the above technical solution: The supporting ring is detachably connected to the receiving shell through bolts, and the size of the receiving shell matches the size of the fiber mesh. The fiber mesh filters the waste again, and dust etc. enter the dust collection groove.

[0014] The utility model has the following beneficial effects:

[0015] A multi-layer sorting device for solid waste treatment designed by the utility model. When waste passes through the first filter plate and the second filter plate for filtration, the gaps of the second filter plate are smaller than those of the first filter plate, so as to carry out sorting filtration. The driving rod is driven by the motor to make the two pushing plates fit the corresponding first filter plate and the second filter plate to rotate, pushing the waste away from the screening cylinder, and at the same time avoiding the situation of accumulation and blockage affecting the flow of materials.

[0016] A multi-layer sorting device for solid waste treatment designed by the utility model, including a first pull-out shell and a second pull-out shell, corresponding to the first filter plate and the second filter plate respectively, which are convenient for carrying the pushed waste, so as to collect the sorted waste. At the same time, the waste filtered by the second filter plate is received by the receiving shell, and the dust and debris are filtered out again through the fiber mesh. The fiber mesh avoids colliding with the waste to generate noise while filtering due to its own flexibility. Brief Description of the Drawings

[0024] As a further implementation of the above technical solution: The pushing plate 404 is in close contact with the first filter plate 405. The pushing plate 404 and the first filter plate 405 form a rotating structure through the driving rod 403. By rotating the pushing plate 404 along the first filter plate 405, the filtered waste is pushed out of the screening cylinder 1.

[0025] As a further implementation of the above technical solution: A second filter plate 5 is fixed below the first filter plate 405 inside the screening cylinder 1. One end of the driving rod 403 located inside the inlet 3 is fixed with a stirring rod 6. Secondary filtering through the second filter plate 5 is convenient for multi-layer sorting. At the same time, the second filter plate 5 is also provided with a pushing plate 404, which is convenient for pushing the filtered waste out of the screening cylinder 1.

[0026] During specific implementation, when the waste enters the screening cylinder 1 through the feeding hopper 2 and the inlet 3, multi-layer sorting and filtering are carried out through the first filter plate 405 and the second filter plate 5. At the same time, the motor 401 is started to drive the driving rod 403, so that the pushing plates 404 corresponding to the first filter plate 405 and the second filter plate 5 push the filtered waste out of the screening cylinder 1 to avoid blockage. At the same time, the stirring rod 6 rotates at the position of the inlet 3 following the driving rod 403 to avoid blockage. A protective shell is arranged outside the motor 401 to prevent bumps when the waste flows through.

[0027] As a further implementation of the above technical solution: A storage mechanism 7 is arranged on the outer wall of the screening cylinder 1. The storage mechanism 7 includes a storage shell 701. The storage shell 701 is fixed on the outer wall of the screening cylinder 1. A first pull-out shell 702 is slidably connected inside the storage shell 701. A second pull-out shell 703 is slidably connected below the first pull-out shell 702 inside the storage shell 701. Anti-collision pads 704 are arranged inside both the first pull-out shell 702 and the second pull-out shell 703.

The receiving shell 705 is used to store smaller wastes and store the smaller materials filtered out again.

[0029] As a further implementation of the above technical solution: A sliding structure is formed between the second sliding shell 703 and the storage shell 701. The second sliding shell 703 is adhesively connected to the anti-collision pad 704. The first sliding shell 702 and the second sliding shell 703 are convenient for sliding out of the storage shell 701 to collect the sorted wastes. At the same time, the anti-collision pad 704 prevents noise caused by bumps.

[0030] As a further implementation of the above technical solution: The supporting ring 707 is detachably connected to the receiving shell 705 by bolts. The size of the receiving shell 705 matches the size of the fiber mesh 706. The fiber mesh 706 filters the wastes again, and dust and the like enter the dust collection groove 708.

[0031] During specific implementation, the materials filtered by the first filter plate 405 and the second filter plate 5 are pushed by the pushing plate 404 and enter the corresponding first sliding shell 702 and second sliding shell 703 for storage respectively, and slide out along the storage shell 701 for convenient unified collection. The receiving shell 705 sliding at the bottom end of the screening cylinder 1 is filtered again by the fiber mesh 706. At the same time, the flexibility of the fiber mesh 706 avoids knocking and colliding with the wastes. A frame is arranged on the outer wall of the fiber mesh 706 and is arranged on the supporting ring 707. The debris, dust and the like are stored through the dust collection groove 708, so that the wastes can be sorted in multiple layers.
