Description

Technical Field

[0001] The utility model relates to the technical field of industrial solid waste treatment, in particular to a separable solid waste screening and treatment device. Background Art

[0002] Industrial solid waste refers to the solid waste generated in industrial production activities. It is a type of solid waste, abbreviated as industrial waste, which includes various waste residues, dusts and other wastes discharged into the environment during the industrial production process. It can be divided into general industrial wastes (such as blast furnace slag, steel slag, red mud, non-ferrous metal slag, fly ash, coal slag, sulfuric acid slag, waste gypsum, desulfurized ash, carbide slag, salt mud, etc.) and industrial hazardous solid wastes, that is, hazardous solid wastes.

[0003] The patent with the publication number of CN220940968U discloses a separable solid waste screening and treatment device, which is provided with a plurality of screening boxes, and a filter screen is arranged inside each screening box. By stacking and installing the plurality of screening boxes, the adjustment of hierarchical screening can be flexibly carried out to achieve finer screening. However, the adjacent two screening boxes of this device are fixedly connected by bolts. Therefore, every time the filter screen inside the screening box is cleaned, the screening boxes need to be disassembled to clean the internal filter screen, resulting in inconvenient cleaning. And every time of screening, the solid waste materials that cannot pass through the filter screen will stay inside the corresponding screening box, resulting in the need to frequently disassemble the screening boxes to pour out the internal solid waste materials, affecting the screening efficiency. Therefore, further improvement is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a separable solid waste screening and treatment device.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Reference Figures 1-4 The utility model provides an embodiment: a sortable solid waste screening and processing device, including a bottom hopper 1, a plurality of stacked screening boxes 3 are installed on the top of the bottom hopper 1, and the top and bottom ends of the screening boxes 3 are open designs, a crushing assembly 4 is installed on the top of the screening box 3 located at the top, a plurality of supporting feet 2 are fixed to the lower surface of the bottom hopper 1, a horizontal strip opening 5 is opened on one side of each screening box 3, a screening assembly 6 is installed inside each screening box 3 and at a position flush with the strip opening 5, one end of the screening assembly 6 passes through the strip opening 5 and is located outside the screening box 3, a discharge opening 7 is opened on the side of the screening box 3 away from the strip opening 5, and a closing assembly 8 is provided on the top of the discharge opening 7.

[0029] The crushing assembly 4 includes a crushing box 41, and the top and bottom ends of the crushing box 41 are both open designs. Two rotating shafts 42 are rotatably connected inside the crushing box 41. Crushing rollers 43 are fixed on the surfaces of the two rotating shafts 42, and one end of the two rotating shafts 42 located outside the crushing box 41 is fixedly connected to a gear 44. The two gears 44 are meshed with each other. A driving motor 45 is fixed to the surface of the crushing box 41 away from the gear 44, and the driving end of the driving motor 45 is fixedly connected to any rotating shaft 42.

[0030] In this embodiment, the two gears 44 are meshed with each other, and the driving motor 45 can drive the two crushing rollers 43 to rotate towards each other, so as to crush the solid waste entering the crushing box 41.

[0031] A plurality of connecting plates 9 are fixed to the bottom end of the crushing box 41, the top end of the bottom bucket 1, and the bottom end and the top end of the screening box 3, and two adjacent connecting plates 9 are fixedly connected by bolts.

[0032] The connecting plate 9 can be used to achieve fixed installation between two adjacent screening boxes 3, and the crushing box 41 can also be fixed to the top of the uppermost screening box 3 through the connecting plate 9, and the lowermost screening box 3 can also be fixed to the top of the bottom bucket 1 through the connecting plate 9.

[0033] The screening assembly 6 comprises a screening plate 61 located inside the screening box 3 , and a screening mesh 62 is fixed in the middle of the screening plate 61 .

[0034] In this embodiment, the mesh sizes of the screen 62 inside each screening box 3 are different, and the mesh sizes gradually decrease from top to bottom, so that the solid waste can be screened step by step.

[0035] The side of the sieve plate 61 close to the strip opening 5 passes through the strip opening 5 and is fixedly connected with a mounting plate 63, and the other side of the mounting plate 63 is fixedly connected with a handle 64. A connecting bolt 65 passes through the top of the mounting plate 63 and is threadedly connected. The outer wall of the screening box 3 is provided with a screw hole 31 for screwing in the connecting bolt 65.

[0036] After being fixedly connected to the outer wall of the screening box 3 through the mounting plate 63, the sieve plate 61 is fixed inside the screening box 3. When it is necessary to disassemble the sieve plate 61 to clean the sieve mesh 62, the connecting bolt 65 can be screwed out from the screw hole 31, and then the sieve plate 61 can be taken out from the strip-shaped opening 5.

[0037] The bottom end of the discharge port 7 is flush with the upper surface of the screening assembly 6. The closing assembly 8 includes a top cavity 81 opened at the top of the discharge port 7, and a baffle 82 is slidably connected inside the top cavity 81. A vertical chute 83 is opened on one side of the top cavity 81 close to the outer surface of the screening box 3. A slide rod 84 is fixed at the top end of the baffle 82 and close to one side of the chute 83, and the slide rod 84 is slidably connected to the chute 83. An external thread is provided on the surface of the slide rod 84 at one end located outside the screening box 3, and an internal thread cap 85 is rotatably connected to the surface of the external thread.

[0038] When the baffle 82 is located inside the discharge port 7, the discharge port 7 is closed. When it is necessary to discharge the solid waste screened out inside the corresponding screening box 3, the internal thread cap 85 can be loosened and moved away from the outer wall of the screening box 3 first, and then the baffle 82 is slid upward through the slide rod 84 to open the discharge port 7. Subsequently, the internal thread cap 85 is screwed to fit the outer wall of the screening box 3 again to fix the slide rod 84 and the baffle 82. Then the device is tilted toward the discharge port 7 side, so that the solid waste can be discharged from the discharge port 7.

[0039] A vibration motor 10 is fixedly installed on the lower surface of the bottom hopper 1. The entire device can be driven to vibrate through the vibration motor 10 to improve the screening efficiency.

[0040] Working principle: An appropriate number of screening boxes 3 can be installed between the bottom hopper 1 and the crushing box 41 according to requirements, and the solid waste is classified and screened by the sieve meshes 62 in the multiple screening boxes 3. During use, after adding the solid waste material into the crushing box 41, the driving motor 45 drives the two crushing rollers 43 to rotate towards each other to crush the solid waste. The crushed solid waste passes through the sieve meshes 62 inside the multiple screening boxes 3 in sequence to achieve multi-stage screening. When it is necessary to discharge the solid waste material inside the screening box 3, the corresponding baffle 82 can be slid upward so that the solid waste is discharged from the discharge port 7 on the screening box 3, and the solid waste passing through the lowest sieve mesh 62 is discharged from the bottom opening of the bottom hopper 1.
