Description

Technical Field

[0001] The utility model relates to the technical field of garbage solid-liquid separation, and more specifically, to a garbage solid-liquid separation device. Background Art

[0002] During the garbage treatment process, the garbage usually needs to be piled up at a designated location first, and then sorted and processed. Since most of the piling locations are outdoors, pits are likely to form on the ground after sorting, resulting in water accumulation. The garbage in the puddle will be mixed with the accumulated water to produce sewage, and the sewage will be mixed with the garbage. At the same time, the garbage piled outdoors will also be mixed with rainwater during rainy days, affecting the treatment of garbage.

[0003] After retrieval, the utility model patent with the publication number of CN217616758U discloses a garbage solid-liquid separation device, including: a machine platform, a crusher, a first pressing machine, a second pressing machine, a liquid waste collection bucket and a solid waste collection bucket; when solid-liquid separation of garbage is required, the garbage is poured from the feeding pipe, the motor drives the shaft rod, and the garbage is crushed by the blade. The crushed garbage falls into the inner cavity due to gravity, and the liquid garbage will flow out from the liquid seepage holes. At the same time, the first pressing machine and the second pressing machine are used to compress the garbage to separate as much liquid garbage remaining in the garbage as possible, and finally the remaining solid garbage is discharged from the discharge port to complete the solid-liquid separation of the garbage.

[0004] However, the above patent still has the following deficiencies: the effect of solid-liquid separation achieved only by the extrusion of the first pressing machine and the second pressing machine on the garbage is poor, and the water stains attached to the outside of the garbage are not easy to fall off. At the same time, when the garbage extruded by the first pressing machine and the second pressing machine needs to be pushed to the discharge port for blanking, it is necessary to prevent the garbage in the crusher from falling into the inner cavity of the machine platform at this time, which is not convenient for continuous solid-liquid separation of the garbage. For this reason, we propose a garbage solid-liquid separation device. Summary of the Utility Model

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a garbage solid-liquid separation device.

[0013] Compared with the prior art, the advantages of the present utility model are as follows:

[0014] (1) In this utility model, a crushing mechanism is used to crush the garbage to be separated into solid and liquid. The crushed garbage and sewage fall into the separation hopper. In addition, the threaded fit between the reciprocating lead screw and the moving seat drives the moving seat and the separation hopper to sway back and forth, so that the garbage and sewage in the inner cavity of the separation hopper generate a swaying feeling, assisting the sewage to fall. In addition, two oppositely rotating extrusion rollers are used to extrude the garbage, so that the sewage in the garbage overflows, realizing the function of effectively separating the solid and liquid of the garbage.

[0015] (2) In this utility model, the separation hopper and the feeding hopper are inclined.

[0027] In this embodiment, the separation bucket 9 is hoisted by using a short suspension rod 6 and a long suspension rod 7. In addition, the separation bucket 9 is tilted to ensure that the solid waste can move along the lower direction of the separation bucket 9 under the action of its own weight.

[0028] For details, please refer to Figure 1 and Figure 3, the extrusion and separation mechanism 11 includes two guiding blocks 18 fixedly connected to the inner wall of the separation hopper 9 and a mounting plate 15 fixedly connected to the top surface of the separation hopper 9. Two second motors 16 are fixedly installed on the top surface of the mounting plate 15. The output shafts of the two second motors 16 extend to the bottom of the mounting plate 15 and are fixedly connected with extrusion rollers 17. The bottom surfaces of the extrusion rollers 17 and the guiding blocks 18 are both in contact with the bottom surface of the inner cavity of the separation hopper 9.

[0029] In this embodiment, the positions of the guiding blocks 18 and the extrusion rollers 17 are adapted to each other. When the garbage is guided by the guiding blocks 18, the garbage just enters between the two extrusion rollers 17.

[0030] Specifically, please refer to Figure 1 and Figure 4 , the crushing mechanism 2 includes a crushing cylinder 19 fixedly sleeved on the workbench 1. A feed inlet 23 is arranged at the top of the crushing cylinder 19. A third motor 20 is fixedly installed on the top surface of the crushing cylinder 19. The output shaft of the third motor 20 extends into the inner cavity of the crushing cylinder 19 and is fixedly connected with a crushing shaft 21. A plurality of crushing knives 22 are fixedly connected to the side surface of the crushing shaft 21.

[0031] In this embodiment, the bottom end of the crushing cylinder 19 is located directly above the inner cavity of the separation hopper 9 so that the garbage falling from the bottom end of the crushing cylinder 19 can be caught by the separation hopper 9.

[0032] Specifically, please refer to Figure 1 , a liquid receiving box 24 is placed directly below the separation hopper 9, and a residue box 25 is placed directly below the bottom end of the material guiding hopper 10.

[0033] In this embodiment, the residue box 25 is used to collect the sewage after solid-liquid separation, and the residue box 25 is used to collect the garbage after solid-liquid separation.

[0034] Specifically, please refer to Figure 2 , the side surface of the moving seat 5 is in contact with the inner wall of the moving box 3.

[0035] In this embodiment, the inner wall of the moving box 3 is used to limit the moving seat 5 so that the moving seat 5 can only move along the axial direction of the reciprocating lead screw 4.

[0036] Specifically, please refer to Figures 1 to 4 , a control panel 26 is fixedly installed on the front surface of the workbench 1. The control panel 26 is electrically connected to the first motor 8, the second motor 16, and the third motor 20 respectively.

[0037] In this embodiment, the control panel 26 is used to control the first motor 8, the second motor 16, and the third motor 20.

[0038] Working principle: When in use, first put the garbage to be separated into the inner cavity of the crushing cylinder 19 from the feeding port 23. At the same time, start the third motor 20 to drive the crushing shaft 21 and the crushing knife 22 to rotate, and use the crushing knife 22 to crush the garbage. The crushed garbage and sewage fall into the inner cavity of the separation hopper 9. Then start the first motor 8 to drive a reciprocating lead screw 4 and a synchronous pulley 13 to rotate. Through the transmission between the two synchronous pulleys 13 and the synchronous belt 14, drive another reciprocating lead screw 4 to rotate. Through the threaded cooperation between the two reciprocating lead screws 4 and the two moving seats 5, drive the separation hopper 9 to reciprocate axially along the reciprocating lead screw 4, so as to shake the garbage in the inner cavity of the separation hopper 9, so that the sewage in the garbage effectively falls into the liquid receiving box 24 from the filtrate holes 12. Then, when the separation hopper 9 shakes, the solid garbage moves downward in the inner cavity of the separation hopper 9 and enters between the two extrusion rollers 17 through the guidance of the guide block 18. At this time, start the two second motors 16 to drive the two extrusion rollers 17 to rotate towards each other inward, and use the two extrusion rollers 17 to extrude the garbage, so that the water in the garbage overflows sufficiently. The overflowed sewage falls into the liquid receiving box 24 from the filtrate holes 12 again. Finally, the extruded solid garbage is exported through the material guiding hopper 10, and the residual material box 25 is used to collect the solid garbage, and that's it.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
