Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, and more specifically it relates to a dehydration device for household waste. Background Technology

[0002] In modern society, with population growth and improved living standards, the amount of household waste generated has increased explosively. Waste contains a large amount of water, and without effective dehydration treatment, it will not only significantly increase subsequent transportation costs and occupy more landfill or incineration space, but also easily breed bacteria and emit foul odors, causing serious environmental pollution and health hazards.

[0003] Traditional methods and devices for dehydrating household waste have many limitations. On the one hand, some small waste disposal sites or communities use a simple natural drainage method, which involves piling up waste in open areas and relying on gravity to allow the moisture to seep out naturally. This method is extremely inefficient, time-consuming, and highly dependent on the weather. It is basically impossible to achieve effective dehydration during the rainy season. At the same time, it occupies a lot of space, emits unpleasant odors, and easily breeds mosquitoes and bacteria, causing secondary pollution to the surrounding environment. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a household waste dewatering device, which has the advantages of achieving rapid, efficient and stable dewatering of household waste, reducing equipment failure rate, improving the degree of waste resource utilization, and properly handling the dewatered water to reduce environmental pollution.

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

[0006] A municipal solid waste dewatering device includes a body, a feeding hopper, a crushing component, a conveying mechanism, a dewatering component, and a collection section. The bottom of the body is provided with several supporting feet. The body includes a first feeding bin and a second feeding bin, with a discharge port between the first feeding bin and the second feeding bin. The feeding hopper is located on the top of the body. The crushing component is located inside the first feeding bin. The crushing component includes a first motor, a second motor, and several crushing rollers. The first motor and the second motor are both located on the right end face of the body. The output ends of the first motor and the second motor both penetrate the body and are connected to the two crushing rollers.

[0007] The conveying mechanism is located below the crushing assembly. The conveying mechanism includes a conveyor belt and a motor. The conveyor belt is located inside the first feeding hopper. The motor is located on the right end face of the machine body. The dewatering assembly includes an electric telescopic rod, a pressing plate, and a pressure plate. The electric telescopic rod is located at the top inside the second feeding hopper. The pressing plate is located at the lower end of the output end of the electric telescopic rod. The pressure plate is located below the pressing plate and has several water outlet holes. The second feeding hopper has a discharge port on the side of the front inner end face of the machine body. A discharge device is provided at the discharge port. The collecting part is located on the front end face of the machine body and is connected to the discharge device of the second feeding hopper. A water outlet valve is provided on the right end face of the machine body and is connected to the second feeding hopper.

[0008] The advantages of this scheme are at least as follows: the crushing mechanism allows for the pulverization of household waste before dewatering, improving dewatering efficiency and reducing the volume of the equipment occupied by the waste. Furthermore, the combined use of the electric telescopic rod, extrusion plate, and pressure plate enables dewatering of the household waste, significantly reducing the burden and costs of subsequent waste transportation. This creates favorable conditions for subsequent waste processing and resource utilization. The crushed waste is discharged through the discharge device, while the water is drained through the outlet to the bottom of the second feeding hopper, facilitating downward water flow and preventing the crushed waste from mixing with the water. Finally, the water is discharged through the outlet valve.

[0009] The present invention is further configured such that the feed hopper is equipped with a flow regulating device.

[0010] The advantages of this scheme are at least as follows: by setting up a flow regulation device, the flow regulation device can reduce the production instability caused by flow fluctuations by precisely controlling the flow of domestic waste.

[0011] The present invention is further configured such that: the bottom of the first feeding hopper is provided with a plurality of drainage holes, and a drainage channel is provided below the drainage holes. The drainage channel is Z-shaped, and the end of the drainage channel is directly connected between the pressure plate and the bottom of the second feeding hopper.

[0012] The advantages of this scheme are at least as follows: by setting up drainage holes and drainage channels, the garbage contains a large amount of water. When it is crushed by the crushing mechanism, the water will inevitably splash onto the inner wall of the first feed bin and adhere to the conveyor belt. Over time, water will accumulate at the bottom of the conveyor belt. The drainage holes can drain the water remaining at the bottom of the conveyor belt and let it flow into the second feed bin through the drainage channels.

[0013] The present invention is further configured such that a filter plate is provided between the pressure plate and the second feed hopper.

[0014] The advantages of this scheme are at least as follows: by installing filter plates, suspended solids, some organic matter, and heavy metal ions can be removed from the water in municipal solid waste. The filtered water enters the bottom of the second feed hopper, and after meeting the discharge standards, it can be reused or safely discharged.

[0015] The present invention is further configured such that an inclined plastic scraper is provided below the end of the conveyor belt.

[0016] The advantages of this scheme are at least as follows: by setting up plastic scrapers, the scrapers can prevent the crushed household waste from adhering to the conveyor belt due to its small size or excessive stickiness, thus avoiding the accumulation of too much household waste under the conveyor belt and causing blockage of the drainage holes, ensuring smooth operation of the conveyor belt and unobstructed drainage.

[0017] The present invention is further provided with a shock-absorbing pad on the bottom of the body on the side away from the support foot.

[0018] The advantages of this solution are at least as follows: by installing shock-absorbing pads, the prolonged compression and vibration of the electric telescopic rod may cause the connections between various components to loosen. The shock-absorbing pads can absorb some of the vibration energy, reducing the impact of vibration on the equipment and thus protecting the various components from damage.

[0019] In summary, this utility model has at least the following advantages:

[0020] 1. By setting up a flow regulation device, the flow regulation device can precisely control the flow of domestic waste, reducing production instability caused by flow fluctuations;

[0021] 2. By setting up drainage holes and drainage channels, the garbage contains a lot of water. When it is crushed by the crushing mechanism, the water will inevitably splash onto the inner wall of the first feed bin and adhere to the conveyor belt. Over time, water will accumulate at the bottom of the conveyor belt. The drainage holes can drain the water remaining at the bottom of the conveyor belt and flow into the second feed bin through the drainage channel.

[0022] 3. By installing filter plates, suspended solids, some organic matter, and heavy metal ions can be removed from the water in domestic waste. The filtered water enters the bottom of feed hopper two, and after meeting the discharge standards, it can be reused or safely discharged.

[0023] 4. By setting up plastic scrapers, the scrapers can prevent the crushed household waste from adhering to the conveyor belt due to its small size or excessive stickiness, thus avoiding the accumulation of too much household waste under the conveyor belt and causing blockage of the drainage holes, ensuring smooth operation of the conveyor belt and unobstructed drainage holes.

[0024] 5. By installing shock-absorbing pads, it can be found that prolonged compression and vibration of the electric telescopic rod may cause the connections of various components to loosen. The shock-absorbing pads can absorb some of the vibration energy, reducing the impact of vibration on the equipment and thus protecting the various components from damage.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0030] A household waste dewatering device, such as Figure 1 and Figure 2As shown, the machine includes a body 1, a feed hopper 2, a crushing assembly 3, a conveying mechanism 4, a dewatering assembly 5, and a collecting section 6. The bottom of the body 1 is provided with several supporting feet 7. The body 1 includes a first feed bin 101 and a second feed bin 102, with a discharge port between them. The feed hopper 2 is located at the top of the body 1. The crushing assembly 3 is located inside the first feed bin 101. The crushing assembly 3 includes a first motor 301, a second motor 302, and several crushing rollers 303. Both the first motor 301 and the second motor 302 are located on the right side of the body 1. The output ends of both the first motor 301 and the second motor 302 penetrate the body 1 and are connected to the two crushing rollers 303. The conveying mechanism 4 is located below the crushing assembly 3 and includes a conveyor belt 401 and a third motor. 402. The conveyor belt 401 is installed inside the first feeding hopper 101. The third motor 402 is installed on the right end face of the machine body 1. The dewatering assembly 5 includes an electric telescopic rod 501, a squeezing plate 502, and a pressure plate 503. The electric telescopic rod 501 is installed at the top inner part of the second feeding hopper 102. The squeezing plate 502 is installed at the lower end of the output end of the electric telescopic rod 501. The pressure plate 503 is installed below the squeezing plate 502 and has several water outlet holes 504. The second feeding hopper 102 has a discharge port on the side near the front inner end face of the machine body 1. A discharge device 8 is installed at the discharge port. The collection part 6 is installed on the front end face of the machine body 1 and connected to the discharge device 8 of the second feeding hopper 102. A water outlet valve 9 is installed on the right end face of the machine body 1 and communicates with the second feeding hopper 102. By setting up the crushing mechanism, the domestic waste can be crushed before dewatering, which can improve the dewatering efficiency and reduce the volume of the device occupied by domestic waste. Furthermore, through the combined use of the electric telescopic rod 501, the compression plate 502, and the pressure plate 503, the municipal solid waste can be dehydrated, greatly reducing the burden of subsequent waste transportation and lowering transportation costs. This creates favorable conditions for subsequent waste treatment and resource utilization. The compressed municipal solid waste is discharged through the discharge device 8, and the water is discharged to the bottom of the feed hopper 102 through the water outlet 504, facilitating downward water flow and preventing the compressed waste from mixing with the water. Finally, the water is discharged through the water outlet valve 9.

[0031] like Figure 1 As shown, a flow regulating device 10 is installed inside the feed hopper 2. By setting the flow regulating device 10, the flow regulating device 10 can precisely control the flow rate of domestic waste, reducing production instability caused by flow fluctuations.

[0032] like Figure 2As shown, the bottom of feed hopper 101 is provided with several drainage holes 11, and a drainage channel 12 is provided below the drainage holes 11. The drainage channel 12 is Z-shaped, and the end of the drainage channel 12 connects directly between the pressure plate 503 and the bottom of feed hopper 2 102. By setting up drainage holes 11 and drainage channels 12, the waste contains a large amount of water. When it is crushed by the crushing mechanism, the water will inevitably splash onto the inner wall of feed hopper 101 and adhere to the conveyor belt 401. Over time, water will accumulate at the bottom of the conveyor belt 401. The drainage holes 11 can drain the residual water at the bottom of the conveyor belt 401 and let it flow into feed hopper 2 102 through the drainage channel 12.

[0033] like Figure 2 As shown, a filter plate 13 is installed between the pressure plate 503 and the second feed hopper 102. The filter plate 13 removes suspended solids, some organic matter, and heavy metal ions from the water in municipal solid waste. The filtered water enters the bottom of the second feed hopper 102, and after meeting discharge standards, it can be reused or safely discharged.

[0034] like Figure 2 As shown, an inclined plastic scraper 14 is provided below the end of the conveyor belt 401. By setting the plastic scraper 14, the scraper can prevent the crushed domestic waste from adhering to the conveyor belt 401 due to its small size or excessive stickiness, thus avoiding the accumulation of too much domestic waste under the conveyor belt 401 and causing the drain hole 11 to become blocked, ensuring the smooth operation of the conveyor belt 401 and the unobstructed flow of the drain hole 11.

[0035] like Figure 1 As shown, a shock-absorbing pad 15 is provided on the bottom of the body 1 on the side away from the support foot 7. By setting the shock-absorbing pad 15, the long-term compression and vibration of the electric telescopic rod 501 may cause the connections of various components to loosen. The shock-absorbing pad 15 can absorb some of the vibration energy, reduce the impact of vibration on the equipment, and thus protect the various components of the equipment from damage.

[0036] The working process and beneficial effects of this utility model are as follows: In use, household waste is first slowly poured into the feed hopper 2. The flow rate adjustment device 10 is adjusted according to the actual processing speed requirements. Subsequently, the household waste falls to the crushing mechanism due to its own pressure, where it is crushed and falls onto the conveyor belt 401. As the conveyor belt 401 runs, the crushed waste falls onto the pressure plate 503. Then, by activating the electric telescopic rod 501, the extrusion plate 502 falls and cooperates with the pressure plate 503 to dehydrate the household waste. The water in the waste then flows from the water outlet 504 onto the filter plate 13 and is discharged to the bottom of the feed bin 102 through the water outlet 504, facilitating downward water flow and preventing the crushed waste from mixing with the water. Finally, the water is discharged through the water outlet valve 9. The crushing mechanism can improve dehydration efficiency and reduce the volume of the device occupied by household waste. This greatly reduces the burden of subsequent waste transportation, lowers transportation costs, and creates favorable conditions for subsequent waste treatment and resource utilization.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
