Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a waste dehydration device for waste treatment. Background Technology

[0002] Garbage is solid waste generated in human daily life and production. Due to its large volume, complex and diverse composition, and its polluting, resource-related, and social characteristics, it requires harmless, resource-recovery, volume-reduction, and socialized treatment. If not properly treated, it will pollute the environment, affect environmental sanitation, waste resources, undermine production and living safety, and disrupt social harmony. In existing technologies, before treating some types of garbage, it is necessary to first separate the solid and liquid components to avoid the liquid in the garbage hindering subsequent treatment. Therefore, it is necessary to use a squeezing dewatering device.

[0003] Some existing extrusion dewatering devices first crush the waste using a crushing component, and then extrude the crushed waste using a centrifugal component. However, crushing the waste increases the contact area between the waste and the outside environment, which may increase the possibility of moisture remaining on the outer surface of the waste, thus affecting the dewatering effect to some extent. Some extrusion dewatering devices use extrusion rollers to squeeze the waste, which alleviates the problem of increased contact area after crushing to some extent, but some long strips of waste may fall directly from the gap between the two extrusion rollers, which will also affect the dewatering effect to some extent. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a squeezing and dewatering device for waste treatment, which can improve the dewatering effect of waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste dewatering and compression device includes a mounting frame, a housing mounted on top of the mounting frame, a feed inlet located on top of the housing, two sets of compression components tightly arranged vertically within the housing, a liquid collection component fixed inside the lower part of the housing and extending one end through the housing to the outside of the housing, a dewatering component rotatably located inside the liquid collection component, and a waste collection box located at the bottom of the housing and connected to the dewatering component after passing through the bottom plate of the housing and the liquid collection component at its top. The compression component includes several parallel compression sub-components arranged inside the housing and rotatably connected at both ends to the inner walls of opposite sides of the housing, and a first motor fixed to the outer wall of the housing for driving the compression sub-components to rotate. The compression sub-component includes a circumferentially rotatable compression roller fixed between the inner walls of opposite sides of the housing and a pair of first gears symmetrically sleeved on the ends of the compression rollers. The first gears in any two adjacent sets of compression sub-components mesh with each other, and the compression rollers in two adjacent sets of compression sub-components abut against each other. The drive end of the first motor passes through the side wall and is connected to the compression roller in one of the compression sub-components.

[0007] More preferably, the liquid collection assembly includes a water storage tank fixed to the top of the tank, a guide plate that surrounds the top of the water storage tank and is inclined downward from the outside to the inside, and a suction pipe that is connected at one end to the water storage tank and extends through the tank to the outside of the tank for use by an external suction mechanism.

[0008] More preferably, the dehydration assembly includes a circumferentially rotatable dehydration tank disposed inside a water storage tank, a connecting pipe disposed at the bottom of the water storage tank and located below the dehydration tank, a second gear disposed between the dehydration tank and the water storage tank and fixedly sleeved outside the connecting pipe, a third gear rotatably connected to the upper surface of the bottom plate of the water storage tank and meshing with the second gear, and a second motor fixedly disposed at the bottom of the box body. The output end of the second motor passes through the bottom plate of the box body and the bottom plate of the water storage tank in sequence and is fixedly disposed in the middle of the third gear. The upper part of the connecting pipe passes through the second gear and communicates with the dehydration tank, and the lower part of the connecting pipe passes through the bottom of the water storage tank and the bottom of the box body in sequence and communicates with the garbage collection bin.

[0009] More preferably, the connecting pipe is equipped with a valve.

[0010] This utility model has the following beneficial effects:

[0011] This invention utilizes two sets of interleaved extrusion components to achieve horizontal and vertical extrusion dehydration of waste. While minimizing the possibility of increased contact area between waste and the outside environment and the possibility of moisture residue remaining on the outer surface of waste due to crushing, it also enables secondary extrusion of waste to improve the dehydration effect. Furthermore, it minimizes the possibility of long strips of waste falling directly downwards from the gap between the two extrusion rollers without being extruded, further enhancing the dehydration effect of waste.

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] A waste dewatering and compression device includes a mounting frame 1, a housing 2 mounted on top of the mounting frame 1, a feed inlet 3 located on top of the housing 2, two sets of compression components 4 tightly arranged vertically within the housing 2, a liquid collection component 5 fixed inside the lower part of the housing 2 with one end extending through the housing 2 to the outside of the housing 2, a dewatering component 6 rotatably located inside the liquid collection component 5, and a waste collection box 7 located at the bottom of the housing 2, with its top end passing through the bottom plate of the housing 2 and the liquid collection component 5 and then communicating with the dewatering component 6; the compression component 4 includes several parallel components arranged inside the housing 2 with their two ends opposite to the sides of the housing 2. The extrusion sub-assembly 41 is rotatably connected to the inner wall, and a first motor 42 is fixed to the outer wall of the housing 2 and used to drive the extrusion sub-assembly 41 to rotate. The extrusion sub-assembly 41 includes an extrusion roller 412 that is rotatably fixed between the inner walls of opposite sides of the housing 2 and a pair of first gears 411 symmetrically sleeved on the ends of the extrusion rollers 412. The first gears 411 in any two adjacent sets of extrusion sub-assemblies 41 mesh with each other, and the extrusion rollers 412 in two adjacent sets of extrusion sub-assemblies 41 abut against each other. The driving end of the first motor 42 passes through the side wall and is connected to the extrusion rollers 412 in one of the extrusion sub-assemblies 41.

[0019] Multiple first gears 411 within each set of extrusion components 4 mesh with each other, thereby driving two adjacent extrusion rollers 412 to rotate in opposite directions, thus achieving extrusion and dehydration of the waste. Through two sets of extrusion components 4 arranged vertically and vertically, extrusion and dehydration of the waste can be achieved in both the transverse and longitudinal directions. While minimizing the possibility of increased contact area between the waste and the outside environment and increased water residue on the outer surface of the waste due to crushing, the waste can be extruded a second time to improve the dehydration effect. On the other hand, it also minimizes the possibility of some long strips of waste falling directly downwards from the gap between the two extrusion rollers 412 without being extruded, further improving the dehydration effect of the waste.

[0020] As a possible implementation of this solution, preferably, the liquid collection assembly 5 includes a water storage tank 51 fixed to the top of the box 2, a guide plate 52 surrounding the top of the water storage tank 51 and inclined downward from the outside to the inside, and a suction pipe 53 with one end connected to the water storage tank 51 and the other end extending through the box 2 to the outside of the box 2 for use with an external suction mechanism; the guide plate 52 can prevent the garbage squeezed by the squeezing roller 412 from falling to the top of the water storage tank 51 or the gap between the water storage tank 51 and the box 2.

[0021] As a possible implementation of this solution, preferably, the dehydration assembly 6 includes a dehydration tank 64 rotatably disposed within a water storage tank 51, a connecting pipe 65 disposed at the bottom of the water storage tank 51 and below the dehydration tank 64, a second gear 61 disposed between the dehydration tank 64 and the water storage tank 51 and fixedly sleeved outside the connecting pipe 65, a third gear 62 rotatably connected to the upper surface of the bottom plate of the water storage tank 51 and meshing with the second gear 61, and a second motor 63 fixedly disposed at the bottom of the housing 2. The output end of the motor 63 passes through the bottom plate of the housing 2 and the bottom plate of the water storage tank 51 in sequence and is fixedly installed in the middle of the third gear 62; the upper part of the connecting pipe 65 passes through the second gear and is connected to the dewatering tank 64, and the lower part of the connecting pipe 65 passes through the bottom of the water storage tank 51 and the bottom of the housing 2 in sequence and is connected to the garbage collection box 7; the second motor 63 drives the third gear 62 to rotate, thereby causing the second gear 61 to drive the dewatering tank 64 to rotate under meshing action, so as to realize the desiccation of the garbage falling into the dewatering tank 64.

[0022] As a possible implementation of this solution, preferably, the connecting pipe 65 is provided with a valve 651; after the spin-drying is completed, the valve 651 is opened, so that the garbage falls through the connecting pipe 65 into the garbage collection bin 7 for collection.

[0023] The working principle of this device is as follows:

[0024] Waste enters the container 2 through the feed inlet 3 and is then squeezed sequentially by the two extrusion components 4 under the action of gravity. It then falls into the dewatering bucket 64. The second motor 63 is turned on, causing the third gear 62 to drive the second gear 61 to rotate, thereby rotating the dewatering bucket 64. This causes the waste in the dewatering bucket 64 to be centrifuged, and the water contained inside is thrown out through the through hole on the dewatering bucket 64. The waste then enters the water storage tank 51 for collection. The water in the water storage tank 51 is then extracted through the suction pipe 53 by a suction mechanism (such as a suction machine or water pump). The spun-dry waste then falls from the connecting pipe 65 into the waste collection bin 7 for collection after the valve 651 is opened.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
