Description

Technical Field

[0001] The invention relates to the technical field of garbage disposal, and in particular to a garbage disposal device used for municipal sanitation. Background Art

[0002] Municipal sanitation refers to the comprehensive management of environmental sanitation in urban public areas, including municipal roads, squares, water areas, public toilets, garbage transfer stations and other urban and rural public areas; municipal sanitation waste treatment mainly includes the treatment of kitchen waste, medical waste, and public toilet waste, and its main tasks include waste classification, collection, storage, transportation and treatment. The management of municipal sanitation waste follows the principles of reduction, resource utilization and harmlessness. Scientific and standardized waste treatment methods can effectively reduce environmental pollution and utilize resources.

[0003] For example, a Chinese patent with publication number CN116020843A discloses a solid-liquid separation device for sanitation engineering waste treatment, including a garbage channel, a cutting mechanism, an extrusion mechanism and a dosing mechanism. The beneficial effect is that the garbage on the filter net can be squeezed by the movement of the extrusion plate in the extrusion mechanism, so that the liquid in the garbage can be better separated from the solid garbage under the cooperation of the cutting mechanism and gravity, thereby improving the solid-liquid separation effect of the garbage.

[0004] However, the solid-liquid separation equipment for sanitation engineering waste treatment has some shortcomings in actual use:

[0005] 1. First, in the above-mentioned prior art, the garbage is crushed by a cutting mechanism, but the garbage is in a moving state, and the crushing effect is poor. At the same time, it only has the effect of crushing, and the effect is single. In the process of garbage treatment, it is required not only to reduce the amount, but also to treat it harmlessly. Therefore, the above-mentioned technology lacks a mechanism for harmlessly treating the garbage.

[0006] 2. Secondly, in the above technology, the garbage on the filter net is squeezed by the squeezing plate, so that the liquid in the garbage can be better separated from the solid garbage, thereby improving the solid-liquid separation effect of the garbage. However, the garbage will be blocked on the filter net, and the separated oil stains will adhere to the filter net, resulting in a decrease in the filtering efficiency of the filter plate, or even causing the filter plate to lose its filtering function.

[0007] Therefore, based on the above-stated viewpoints, there is still room for improvement in existing garbage disposal devices. Summary of the invention

Detailed implementation mode

[0041] The following will Figure 1-Figure 13 be described in detail with reference to the embodiments of the present invention. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0042] The embodiments of the present application disclose a garbage treatment device for municipal environmental sanitation. It should be noted that this garbage treatment device for municipal environmental sanitation is mainly applied in the process of garbage treatment. In terms of technical effects, it can avoid the problem of blockage of the U-shaped filter plate 11 during the solid-liquid separation of garbage, resulting in a reduction in garbage treatment efficiency; especially during the extrusion of garbage, the traditional device only extrudes the garbage through the extrusion plate, which will cause garbage and oil stains to adhere to the filter holes 110 in the U-shaped filter plate 11, thereby causing blockage of the U-shaped filter plate 11; furthermore, the present invention can also improve the crushing effect of garbage; finally, the present invention can clean the garbage, achieve harmless treatment, and facilitate the subsequent recycling of garbage.

[0043] Embodiment 1:

[0044] Refer to Figure 1 、 Figure 2 and Figure 3As shown, a garbage disposal device for municipal sanitation includes a shell 1, a crushing mechanism 2 and an extrusion mechanism 3. The shell 1 is arranged on the ground, and the crushing mechanism 2 and the extrusion mechanism 3 are both arranged inside the shell. The crushing mechanism 2 is used for crushing and cutting the garbage to facilitate the subsequent extrusion treatment, which can greatly reduce the volume of the garbage. At the same time, the garbage is stirred during the crushing process to improve the cleaning and disinfection effects of detergents and disinfectants on the garbage, thereby achieving harmless treatment.

[0045] The crushing mechanism 2 also includes a No. 1 hydraulic cylinder 20, a crushing connecting rod 21, a No. 2 shell 22 and a crushing unit 23. The No. 1 hydraulic cylinder 20 is vertically arranged on the inner wall of the No. 1 shell 1, and its output end is vertically downward, and is used to raise and lower the crushing unit 23. The crushing connecting rod 21 is vertically arranged at the output end of the No. 1 hydraulic cylinder 20. The No. 2 shell 22 is arranged at the bottom of the crushing connecting rod 21 as a shell to protect the DC motor 230 and the transmission unit 5. The crushing unit 23 is arranged inside the No. 2 shell 22.

[0046] It should be noted that the hydraulic cylinder is an existing known structure. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and is widely used in hydraulic systems of various machines. It can push or pull a load through a linear drive mechanism, or use fluid pressure to selectively prevent movement under load.

[0047] When the No. 1 hydraulic cylinder 20 rises and falls, it drives the crushing connecting rod 21, the No. 2 shell 22 and the crushing unit 23 to rise and fall synchronously.

[0048] Reference Figure 4 As shown, a No. 3 shell 6 is also provided at the bottom of the No. 2 shell 22. The No. 3 shell 6 is a cubic structure with an opening facing downward, which serves as a working area for garbage crushing and processing. A feed port 60 is also provided at the top of the No. 3 shell 6 for pouring garbage, detergent, disinfectant and water into the No. 3 shell 6.

[0049] It should be noted that the rising and falling of the second housing 22 will drive the third housing 6 to rise and fall synchronously.

[0050] First, start the No. 1 hydraulic cylinder 20, which drives the No. 3 shell 6 to descend synchronously until the No. 3 shell 6 is against the L-shaped bottom plate 10. At this time, the No. 3 shell 6 and the L-shaped bottom plate 10 form a closed working area, and garbage, detergent, disinfectant and water are poured into the No. 3 shell 6 through the feed port 60 for subsequent crushing processing.

[0051] Replay Figure 3As shown, the crushing unit 23 used for crushing, cutting and mixing garbage in the invention, specifically, the crushing unit 23 also includes a DC motor 230, a connecting shaft 231 and a rotating blade 232, the DC motor 230 is vertically arranged on the inner wall of the No. 2 shell 22, and the output end of the DC motor 230 faces the No. 3 shell 6, which is used to provide the power required for the rotating blade 232 to work, two symmetrically distributed connecting shafts 231 are vertically penetrated through the top of the No. 3 shell 6, and one of them is arranged at the output end of the DC motor 230, and a number of equidistantly distributed rotating blades 232 are horizontally arranged on the connecting shaft 231, which are used to crush, cut and mix the garbage, so that the detergent, disinfectant and water can fully clean and disinfect the garbage.

[0052] It should be noted that the DC motor 230 is a known structure. The DC motor 230 mainly includes two parts: a stator and a rotor. The DC motor 230 is a rotating motor that converts electrical energy into mechanical energy and is widely used in various occasions requiring precise control and speed regulation.

[0053] Replay Figure 3 As shown, a transmission unit 5 is provided on the connecting shaft 231. Specifically, a transmission unit 5 is provided on the connecting shaft 231. The transmission unit 5 includes a rotating gear 50 and a rotating belt 51. Two symmetrically distributed rotating gears 50 are horizontally arranged on the two connecting shafts 231, and the rotating gears 50 and the connecting shafts 231 are coaxially distributed. The rotating belt 51 is sleeved on the two rotating gears 50, and the rotating belt 51 is meshed with the rotating gear 50.

[0054] It should be noted that when the DC motor 230 is working, it only drives one connecting shaft 231 to rotate. When the connecting shaft 231 rotates, it will drive the rotating gear 50 connected to it to rotate, and then the rotating gear 50 drives the rotating belt 51 to rotate, and then the rotating belt 51 drives another rotating gear 50 to rotate, and finally the rotating gear 50 drives another connecting shaft 231 to rotate, thereby realizing the effect of one DC motor 230 driving two connecting shafts 231, reducing equipment costs and improving the efficiency of crushing and cutting.

[0055] During the specific implementation process, after garbage, detergent, disinfectant and water are poured into the No. 3 shell 6, the DC motor 230 is started. The DC motor 230 drives the rotating blade 232 to rotate rapidly through the connecting shaft 231, thereby crushing and cutting the garbage into granular solid waste. While the rotating blade 232 rotates rapidly, it stirs the garbage, allowing the detergent, disinfectant and water to fully contact the garbage, thereby achieving the cleaning and disinfection effect on the garbage, realizing the harmless treatment of the garbage, and facilitating subsequent recycling and utilization.

[0056] Reference Figure 5As shown, the extrusion mechanism 3 for compressing the volume of garbage and squeezing out liquid in the present invention. Specifically, the extrusion mechanism 3 further includes a second hydraulic cylinder 30, a first spring telescopic sleeve 31, and an L-shaped extrusion plate 32. The second hydraulic cylinder 30 is horizontally arranged on the inner wall of the first housing 1. The first spring telescopic sleeve 31 is horizontally arranged at the output end of the second hydraulic cylinder 30. The L-shaped extrusion plate 32 is arranged at the end of the first spring telescopic sleeve 31 away from the second hydraulic cylinder 30.

[0057] The spring telescopic sleeve is a known structure in the prior art. It consists of an inner telescopic rod and an outer telescopic sleeve, and realizes length change and stable support through an internal movable spring device and a compression spring device. It is a sleeve whose length can be adjusted.

[0058] Refer to Figure 6 As shown, an L-shaped bottom plate 10 is further arranged on the first housing 1. The L-shaped bottom plate 10 is rotatably arranged along the horizontal direction at the bottom of the first housing 1. A square card interface 100 is opened on the L-shaped bottom plate 10.

[0059] Refer to Figure 7 As shown, a U-shaped filter plate 11 for filtering liquid is further arranged on the first housing 1. The U-shaped filter plate 11 is arranged inside the first housing 1, and is located at the top of the L-shaped bottom plate 10 and at the bottom of the third housing 6 at the same time. The U-shaped filter plate 11, the L-shaped bottom plate 10, and the third housing 6 form a working area for processing garbage. A number of equally spaced filter holes 110 are opened on the U-shaped filter plate 11. A cavity area 111 is arranged between the U-shaped filter plate 11 and the first housing 1. Liquid flows into the cavity area 111 through the filter holes 110.

[0060] Refer to Fig. 9 、 Fig.10 and Fig.11 As shown, the L-shaped extrusion plate 32 is further provided with an extrusion transmission unit 7. Specifically, the extrusion transmission unit 7 includes an I-shaped limit post 70, a U-shaped rack 71, a first rotating shaft 72, a first gear 73, a second gear 74, and a linear rack 75. The I-shaped limit post 70 is arranged on the side of the L-shaped extrusion plate 32 close to the second hydraulic cylinder 30, and is used to limit the positions of the U-shaped rack 71 and the first rotating shaft 72. One end of the U-shaped rack 71 penetrates through the top of the L-shaped extrusion plate 32, and the other end is sleeved on the I-shaped limit post 70. The first rotating shaft 72 is horizontally arranged on the I-shaped limit post 70. The first gear 73 and the second gear 74 are coaxially arranged on the first rotating shaft 72, and the first gear 73 meshes with the U-shaped rack 71. The linear rack 75 is horizontally arranged on the first spring telescopic sleeve 31, and the second gear 74 meshes with the linear rack 75.

[0061] It should be noted that when the L-shaped extrusion plate 32 is extruded to a certain position, the first spring telescopic sleeve 31 starts to expand and contract, causing the linear rack 75 to move towards the L-shaped extrusion plate 32. The linear rack 75 drives the second gear 74 to rotate, and then the first gear 73 coaxially distributed with the second gear 74 starts to rotate. Finally, the first gear 73 drives the U-shaped rack 71 to move downward.

[0062] Referring to Fig.11 , Fig.12 and Fig.13 As shown, an extrusion adjustment unit 8 is further provided on the U-shaped rack 71. The extrusion adjustment unit 8 includes a first horizontal plate 80, a second horizontal plate 81, an internal rack 82, a third gear 83, a second rotating shaft 84 and a pin handle 85. The first horizontal plate 80 is horizontally arranged at the bottom of the U-shaped rack 71 and abuts against the inner side of the L-shaped extrusion plate 32. The second horizontal plate 81 is sleeved on the first horizontal plate 80. The internal rack 82 is arranged on one side of the second horizontal plate 81 close to the first horizontal plate 80. The internal rack 82 meshes with the third gear 83. The second rotating shaft 84 is rotatably arranged on the first horizontal plate 80. At the same time, the second rotating shaft 84 horizontally passes through the axis of the third gear 83. The pin handle 85 is arranged at one end of the second rotating shaft 84, and the pin handle 85 and the second rotating shaft 84 are in a pin structure. Only when it is necessary to adjust the length of the first horizontal plate 80 and the second horizontal plate 81, the pin handle 85 and the second rotating shaft 84 are spliced, and the second rotating shaft 84 is driven to rotate by rotating the pin handle 85.

[0063] It should be noted that when the pin handle 85 is manually rotated, the pin handle 85 drives the third gear 83 to rotate through the second rotating shaft 84. Then, the third gear 83 drives the internal rack 82 to rotate. Finally, the internal rack 82 drives the second horizontal plate 81 to move, so as to achieve the effect of adjusting the length.

[0064] In the specific implementation process, when the garbage is fully crushed, the first hydraulic cylinder 20 is activated to lift the third housing 6 and the crushing unit 23 until they are above the U-shaped filter plate 11 and the L-shaped extrusion plate 32. Then, the second hydraulic cylinder 30 is activated, and the L-shaped extrusion plate 32 is pushed towards the U-shaped filter plate 11 through the first spring telescopic sleeve 31. During the movement, the U-shaped filter plate 11, the L-shaped extrusion plate 32, and the L-shaped bottom plate 10 form an extrusion working area, and the extrusion working area continuously becomes smaller, thereby continuously extruding the crushed garbage. When extruded to a certain position, the first spring telescopic sleeve 31 starts to contract, driving the first gear 73 and the second gear 74 to rotate, and thus driving the first horizontal plate 80 and the second horizontal plate 81 to extrude towards the garbage through the U-shaped rack 71. Finally, under the extrusion of the L-shaped extrusion plate 32, the first horizontal plate 80, and the second horizontal plate 81, the granular garbage is extruded into a块状 solid, greatly reducing the volume of the garbage and achieving reduction treatment. At the same time, during the extrusion process, the liquid in the garbage is fully discharged through the filter holes 110, improving the effect of solid-liquid separation.

[0065] Refer to Figure 8 As shown, a second spring telescopic sleeve 12 and a clamping convex block 13 are further provided on the first housing 1. The second spring telescopic sleeve 12 is horizontally arranged on the inner wall of the first housing 1, and the clamping convex block 13 is arranged at one end of the second spring telescopic sleeve 12 close to the L-shaped extrusion plate 32, and the clamping convex block 13 is matched with the square clamping port 100.

[0066] It should be noted that in the initial state, the second spring telescopic sleeve 12 extrudes the clamping convex block 13, so that the clamping convex block 13 is in a state of being clamped with the square clamping port 100. Under the action of clamping, the L-shaped bottom plate 10 is in a horizontal placement state. When the L-shaped extrusion plate 32 moves towards the clamping convex block 13, the second spring telescopic sleeve 12 starts to contract, and the clamping convex block 13 moves away from the L-shaped bottom plate 10, causing the clamping convex block 13 to be disengaged from the square clamping port 100. Under the action of gravity, the L-shaped bottom plate 10 rotates to a vertical state.

[0067] In the specific implementation process, when the garbage is fully extruded, the second hydraulic cylinder 30 starts to drive the L-shaped extrusion plate 32 to move towards the clamping convex block 13 until the L-shaped extrusion plate 32 abuts against the clamping convex block 13 and causes the clamping convex block 13 to be disengaged from the square clamping port 100. The L-shaped bottom plate 10 is opened under the action of gravity. At the same time, under the action of gravity, the块状 garbage automatically falls and is collected manually. Then, the operator rotates the L-shaped bottom plate 10 to a horizontal state, activates the second hydraulic cylinder 30 to drive the L-shaped extrusion plate 32 to move away from the clamping convex block 13. Under the telescopic action of the second spring telescopic sleeve 12, the clamping convex block 13 moves towards the square clamping port 100 and is clamped with it, making the L-shaped bottom plate 10 in a stable horizontal placement state.

[0068] Looking back Figure 1 As shown, a second infusion tube 14 and an oil-water separator 15 are further provided on the first housing 1. One end of the second infusion tube 14 is provided on the first housing 1, and the other end is provided on the oil-water separator 15. Moreover, the cavity area 111 formed between the U-shaped filter plate 11 and the first housing 1 is communicated with the infusion tube, and the oil-water separator 15 is arranged on the ground.

[0069] It should be noted that the oil-water separator 15 is a known structure. The oil-water separator 15 is a device used to separate oil and water in oily sewage, and its design principle is mainly based on the density difference between two liquids. This kind of device is widely used in industrial production, environmental protection treatment and daily life, such as ships, the catering industry, the chemical industry, etc.

[0070] In the specific implementation process, when the liquid flows into the cavity area 111, it flows into the second infusion tube 14 through the cavity area 111, and then into the oil-water separator 15. Under the separation effect of the oil-water separator 15, oil and water are extracted from the liquid for subsequent purification and treatment, so as to realize the recovery of grease in the garbage and achieve the resource treatment of the garbage.

[0071] Embodiment 2:

[0072] Referring to Figure 1 and Figure 4 As shown, on the basis of Embodiment 1, in order to improve the efficiency of solid-liquid separation of garbage and prevent the U-shaped filter plate 11 from being blocked, a cleaning unit 4 for removing oil stains and attachments on the U-shaped filter plate 11 is further provided on the third housing 6. Specifically, the cleaning unit 4 includes atomizing nozzles 40, an infusion tank 41, a first infusion tube 42 and a liquid storage tank 43. The atomizing nozzles 40 distributed in a matrix are arranged on the side wall of the third housing 6, and atomizing nozzles 40 are provided on both the inner wall and the outer wall of the third housing 6 for cleaning the U-shaped filter plate 11 and the rotary blade 232. The third housing 6 is provided with an infusion tank 41 for liquid to flow through. The infusion tank 41 is communicated with the atomizing nozzles 40 to convey water containing degreasing agent to the atomizing nozzles 40. One end of the first infusion tube 42 is provided on the top of the third housing 6, and the other end is provided on the top of the liquid storage tank 43 for conveying water containing degreasing agent to the infusion tank 41. The liquid storage tank 43 is arranged on the ground for storing water containing degreasing agent.

[0073] During the specific implementation process, after the L-shaped bottom plate 10 returns to a stable horizontal placement state, the first hydraulic cylinder 20 is activated to lower the third housing 6 until the third housing 6 descends to abut against the L-shaped bottom plate 10. The liquid storage tank 43 starts to convey water containing degreasing agent to the liquid infusion tank 41 through the first liquid infusion pipe 42. Then, the atomizing nozzle 40 starts to wash the U-shaped filter plate 11 and the rotary blade 232. The water containing degreasing agent decomposes and flushes away the oil stains, thereby cleaning the U-shaped filter plate 11 and the rotary blade 232. Then, garbage, cleaning agent, disinfectant, and water are poured into the third housing 6 to start the next round of garbage disposal operation.

[0074] During operation: In the first step, the first hydraulic cylinder 20 is activated. The first hydraulic cylinder 20 drives the third housing 6 to descend synchronously until the third housing 6 abuts against the L-shaped bottom plate 10. Then, garbage, cleaning agent, disinfectant, and water are poured into the third housing 6 through the feed port 60.

[0075] In the second step: The DC motor 230 is activated. The DC motor 230 drives the rotary blade 232 to rotate rapidly through the connecting rotating shaft 231, thereby crushing and cutting the garbage into granular solid waste. While the rotary blade 232 rotates rapidly, it stirs the garbage, enabling the cleaning agent, disinfectant, and water to come into full contact with the garbage, thereby achieving the cleaning and disinfection of the garbage.

[0076] In the third step: When the garbage is fully crushed, the first hydraulic cylinder 20 is activated to lift the third housing 6 and the crushing unit 23 until they are above the U-shaped filter plate 11 and the L-shaped pressing plate 32. Then, the second hydraulic cylinder 30 is activated, and the L-shaped pressing plate 32 is pushed towards the U-shaped filter plate 11 through the first spring telescopic sleeve 31. During the movement, the crushed garbage is continuously squeezed, and finally the granular garbage is squeezed into a块状 solid.

[0077] In the fourth step: When the garbage is fully squeezed, the second hydraulic cylinder 30 starts to drive the L-shaped pressing plate 32 to move towards the clamping convex block 13 until the L-shaped pressing plate 32 abuts against the clamping convex block 13 and causes the clamping convex block 13 to disengage from the square clamping port 100. The L-shaped bottom plate 10 is opened under the action of gravity. At the same time, under the action of gravity, the块状 garbage automatically falls and is collected manually. Then, the L-shaped bottom plate 10 is manually rotated to the horizontal state, and the second hydraulic cylinder 30 is activated to drive the L-shaped pressing plate 32 to move away from the clamping convex block 13. Under the telescopic action of the second spring telescopic sleeve 12, the clamping convex block 13 moves towards the square clamping port 100 and is clamped with it, making the L-shaped bottom plate 10 in a stable horizontal placement state.

[0078] In the fifth step: When the liquid flows into the cavity area 111, it flows into the second liquid infusion pipe 14 through the cavity area 111, and then into the oil-water separator 15. Under the separation action of the oil-water separator 15, oil and water are extracted.

[0079] Step 6: After the L-shaped bottom plate 10 returns to a stable horizontal placement state, start the first hydraulic cylinder 20 to lower the third housing 6 until the third housing 6 abuts against the L-shaped bottom plate 10. Then, the liquid storage tank 43 conveys water containing degreasing agent to the liquid injection tank 41 through the first liquid delivery pipe 42. Furthermore, the atomizing nozzle 40 starts to wash the U-shaped filter plate 11 and the rotary blade 232, cleaning the U-shaped filter plate 11 and the rotary blade 232. Then, pour garbage, cleaning agent, disinfectant, and water into the third housing 6 to start the next round of garbage disposal operation.
