Description

Technical Field

[0001] This invention relates to the field of waste utilization, and more specifically to an integrated device for treating municipal solid waste. Background Technology

[0002] With the rapid pace of urbanization, waste management has become a critical issue urgently needing resolution. Household food waste, a major component of daily waste, is particularly problematic due to its large volume and perishable nature. Improper handling not only occupies significant land resources but also easily breeds bacteria and emits unpleasant odors, causing serious secondary pollution of soil, water, and air, thus harming the ecological environment and residents' health. According to relevant data, the average urban resident in my country generates approximately 0.3-0.5 kg of food waste per day. In just 46 key cities, the daily volume of food waste collected reaches as high as 130,000 tons, demonstrating its immense scale. Against this backdrop, kitchen waste treatment equipment has emerged, and its importance is self-evident. This type of equipment can reduce, render harmless, and recycle kitchen waste, such as converting it into organic fertilizer or animal feed, or producing biogas for energy supply through anaerobic fermentation. It effectively reduces environmental pressure, improves resource utilization efficiency, and plays an indispensable role in the field of waste treatment.

[0003] The resource utilization of household kitchen waste requires processing with specialized equipment. However, existing processing equipment has many problems that need to be solved. First, the equipment has a simple structural design and lacks the ability to process fruit and vegetable scraps in an integrated manner, resulting in a large amount of labor costs and low efficiency in the processing stage. Second, in the dehydration operation of such scraps, the equipment cannot achieve alternating processing, and the discharge of material residue has not formed a linkage mechanism, resulting in poor connection of the operation process.

[0014] The beneficial effects of this invention are: This invention overcomes the limitations of traditional single-structure designs by coordinating the operation of the filter press, feeding, and limiting components. It establishes an integrated processing flow for fruit and vegetable scraps, encompassing compression, filtration, feeding, and solid-liquid separation. This eliminates the need for manual batch feeding of scraps; the equipment autonomously completes the entire process from compression and filtration to feeding and solid-liquid separation. This significantly reduces manual input, lowers management and operational costs, and avoids efficiency fluctuations caused by human intervention. Furthermore, the integrated process shortens the processing cycle per batch, completely resolving the efficiency bottleneck of traditional equipment that relies on segmented processing and manual intervention. It is particularly suitable for high-frequency, high-volume kitchen waste processing scenarios such as large communities, farmers' markets, and concentrated catering areas, meeting the needs of large-scale resource utilization. This invention, by setting two sets of filter press blocks inside the limiting component, can adopt a dual-compartment alternating dewatering structure to address the high moisture and high fiber characteristics of fruit and vegetable scraps. When one compartment is dewatering, the other compartment can simultaneously complete the raw material feeding and pretreatment. The two compartments cycle alternately to achieve "uninterrupted dewatering". Compared with traditional single-compartment dewatering equipment, the dewatering efficiency per unit time is improved, effectively avoiding energy waste caused by equipment idling. When the filter press blocks rise to the target height, the front and rear push plates can simultaneously slide and automatically discharge the material residue without manual judgment or operation. This avoids equipment blockage caused by material residue accumulation and eliminates the process breakpoint of "dewatering stagnation - manual slag removal - restart operation", improving the overall processing efficiency and further ensuring the continuous and stable operation of the equipment. This invention utilizes a filter press, a feeding component, and a limiting component to perform integrated processing of household waste, fruit and vegetable scraps. This avoids significant labor costs in the processing stage, improves efficiency, and enables alternating processing of these scraps during dewatering. Furthermore, the equipment features a linkage mechanism for material and residue discharge, ensuring a smooth workflow and meeting people's processing needs. Attached Figure Description

[0019] Please see Figures 1-8 As shown, the present invention is an integrated device for municipal solid waste treatment, including a limiting component 3, a feeding component 2 movably disposed at the bottom end of the limiting component 3, and a filter press component 1 disposed at the top of the limiting component 3.

A power distribution cabinet 31 is fixedly installed on the upper side of the processing chamber 317 and at the top of the support frame 311. A drive motor 310 is fixedly installed on the side of the processing chamber 317 and directly below the power distribution cabinet 31. A limit frame 39 is welded below the material receiving hopper 37 on the front side of the processing chamber 317. A threaded rod 38 is rotatably engaged in the lower middle part of the limit frame 39. A limit slide 316 is opened below the rear end face of the processing chamber 317. A discharge guide plate 314 is set at the bottom of the limit slide 316 on the rear end face of the processing chamber 317. A water collection tank 319 is set at the bottom end face of the processing chamber 317. A drain pipe 313 is set at the bottom center of the water collection tank 319. A filter plate 312 is slidably inserted into the bottom of the discharge port 315 on the front side of the processing chamber 317. A compression chamber 321 is symmetrically arranged inside the processing chamber 317. The bottom of the compression chamber 321 is symmetrically provided with limiting slides 316 on both sides. One end of the limiting slide 316 is provided with a limiting wheel 320 near the discharge port 315. The top surface inside the compression chamber 321 is provided with a slot 322. The cleaning shaft 318 is uniformly rotated and engaged inside the water collection tank 319 and below the filter plate 312. A transmission sprocket is fixedly installed on the outer surface of one end of the cleaning shaft 318. A transmission chain is meshed with the outer surface of the transmission sprocket.

[0022] The top center of the processing chamber 317 has symmetrical through holes. The filter block 13 is slidably inserted into the interior of the processing chamber 317 through the compression chamber 321, which can compress the waste inside the compression chamber 321. The L-shaped connecting rod 16 on the top of the filter block 13 is slidably inserted into the top of the processing chamber 317 through the through holes. The partition 11 on the top of the filter block 13 is slidably inserted into the slot 322, which facilitates the lifting and lowering of the partition 11 and avoids obstruction.

[0023] The baffle 36 is inserted through the bottom surface of the receiving hopper 37, which facilitates the lifting and lowering of the baffle 36 to divide the garbage accumulated on the upper surface of the receiving hopper 37, thereby enabling the distribution and disposal of garbage. The transmission rod 33 is connected to the transmission gear 12 on the side of the partition 11 through the external transmission gear 32. When the partition 11 is lifted or lowered, it drives the transmission rod 33 and the winding reel 34 to wind and unwind the second traction rope 35, thereby synchronously controlling the lifting and lowering of the baffle 36. The hydraulic cylinder 15 is fixedly connected to the back of the processing chamber 317 through the limiting plate 17. The L-shaped connecting rod 16 is fixedly connected to the first traction rope 26 through the connecting brackets 14 on both sides of the top. When the L-shaped connecting rod 16 is lifted or lowered, it controls the reciprocating sliding of the front push plate 22 and the rear push plate 25.

[0024] The front push plate 22 and the rear push plate 25 are connected to the interior of the processing chamber 317 via the discharge port 315 at the bottom of the back of the processing chamber 317. The outer end face of the front push plate 22 is fixedly connected to one end of the first traction rope 26. The middle section of the first traction rope 26 is slidably overlapped on the outer surface of the limiting wheel 320 inside the bottom of the compression chamber 321. Through the traction and reset action of the first traction rope 26, the front push plate 22 can be driven to slide back and forth along the discharge port 315, thereby pushing the compressed slag between the front push plate 22 and the rear push plate 25 to move to the outside of the discharge port 315, realizing the automatic removal of the compressed slag. In addition, the middle part of the filter plate 312 is connected to the threaded rod 38 by a thread. When the filter plate 312 is blocked, the filter plate 312 can be driven to slide along the preset slide by rotating the threaded rod 38, so that the filter plate 312 is exposed to the outside of the equipment, which is convenient for the staff to clear the blockage and maintain it. The output end of the drive motor 310 is fixedly connected to one end of the cleaning shaft 318. The cleaning shaft 318 is rotatably mounted inside the water collection tank 319, and the cleaning structure on the outer surface of the cleaning shaft 318, such as a brush, is in close contact with the bottom surface of the filter plate 312. When the drive motor 310 starts, it can drive the cleaning shaft 318 to rotate around its own axis, and the cleaning structure brushes the impurities attached to the bottom surface of the filter plate 312, effectively preventing the filter holes of the filter plate 312 from clogging. In addition, the pressure spring block 27 has symmetrically opened sleeve holes on both sides. The pressure spring block 27 forms a sliding sleeve engagement with the outer surface of the limiting frame 39 through the sleeve holes. The limiting frame 39 can precisely limit the sliding trajectory of the pressure spring block 27, avoid the pressure spring block 27 from deviating when sliding, and ensure the stable realization of the elastic reset function of the return spring 21. The working principle of this invention: This integrated equipment for municipal solid waste treatment achieves automated compression, dehydration, solid-liquid separation, and resource recovery of kitchen waste containing fruit and vegetable scraps through the coordinated linkage of the filter press component 1, the feeding component 2, and the limiting component 3. The specific workflow is as follows: Before starting the equipment to process kitchen waste, the kitchen waste to be processed, such as leftover food, fruit and vegetable scraps, etc., must be poured into the receiving hopper 37 at the upper front end of the limiting component 3. The inner wall of the receiving hopper 37 is preferably inclined at an angle of 30°-45°. Utilizing gravity, some of the kitchen waste will naturally slide down the inclined surface of the receiving hopper 37 and eventually fall into the compression chamber 321 symmetrically arranged inside the processing chamber 317, completing the initial feeding and positioning; the remaining waste that does not slide down is temporarily stored on the upper surface of the receiving hopper 37, waiting to enter the compression chamber 321 in batches later. After sufficient kitchen waste is added to the compression chamber 321, a control command is sent through the power distribution cabinet 31 to start the hydraulic cylinders 15 that are symmetrically fixed to the outside of the limit plate 17 in the filter press component 1. The output shaft of the hydraulic cylinder 15 extends downward synchronously, driving the L-shaped connecting rod 16 fixedly connected to its top to move downward in the vertical direction. Since the bottom end of the L-shaped connecting rod 16 is rigidly fixed to the filter press block 13, and the filter press block 13 is slidably inserted into the compression chamber 321 through the pre-set insertion hole at the top of the processing chamber 317, the L-shaped connecting rod 16 will synchronously drive the filter press block 13 to descend smoothly in the vertical direction inside the compression chamber 321. During the descent of the filter block 13, its bottom plane comes into full contact with the kitchen waste in the compression chamber 321 and applies pressure to dehydrate the kitchen waste containing moisture. Since the bottom of the compression chamber 321 is covered with a filter plate 312, which is slidably inserted into the slide at the bottom of the discharge port 315 on the front face of the processing chamber 317 and covers the entire bottom cross section of the compression chamber 321, the juice generated by the compression will penetrate the gaps between the solid particles of the kitchen waste and drip down through the filter holes of the filter plate 312, eventually collecting in the water collection tank 319 set at the bottom face of the processing chamber 317. The drain pipe 313 at the bottom center of the water collection tank 319 can be connected to an external pipe to export the collected juice to a storage container. Subsequently, it can be used to make organic fermentation liquid through fermentation process to realize the resource utilization of the juice. When the kitchen waste in the compression chamber 321 is compressed, the compression pressure can be adjusted by the output pressure of the hydraulic cylinder 15 through the distribution cabinet 31. The distribution cabinet 31 then controls the output shaft of the hydraulic cylinder 15 to retract, causing the filter block 13 to rise vertically and reset inside the compression chamber 321. Since the connecting brackets 14 on both sides of the top of the L-shaped connecting rod 16 are fixedly connected to one end of the first traction rope 26 in the feeding component 2, and the other end of the first traction rope 26 is fixed to the outer side of the front push plate 22, and the middle section of the first traction rope 26 slides and overlaps on the outer surface of the limiting wheel 320 inside the bottom of the compression chamber 321, the limiting wheel 320 can reduce the frictional loss of the first traction rope 26 during movement. Therefore, the filter block 13 will be pulled by the connecting brackets 14 during the upward movement. The first traction rope 26 drives the front push plate 22 to slide horizontally inside the discharge port 315 at the bottom of the back of the processing chamber 317. The front push plate 22 is fixedly connected to the rear push plate 25 through the second connecting rod 24. The two move synchronously, pushing the compressed slag block located between the front push plate 22 and the rear push plate 25. After compression, the volume is reduced to 1 / 3-1 / 5 of the original volume and slides outward along the discharge port 315 until the compressed slag block leaves the discharge port 315 and falls onto the upper surface of the discharge guide plate 314 set at the bottom of the limit slide 316 at the rear end of the processing chamber 317. The discharge guide plate 314 is inclined, and the compressed slag block can slide down its inclined surface into the collection device below, which can then be used to make livestock and poultry feed, realizing the recycling and reuse of solid slag blocks. When the bottom of the filter block 13 rises to be flush with the bottom of the receiving hopper 37, the first traction rope 26 is no longer pulled and enters the release state. At this time, the spring block 27 connected to the other side of the front push plate 22 in the feeding component 2 via the first connecting rod 23 compresses the reset spring 21 because the front push plate 22 previously slid, causing the first connecting rod 23 to compress the reset spring 21. The reset spring 21 is sleeved on the outside of the first connecting rod 23, and its two ends abut against the spring block 27 and the inner wall of the processing chamber 317, respectively. The elastic potential energy stored in the reset spring 21 is released, pushing the spring block 27 to slide along the outer surface of the limiting frame 39. The spring block 27 slides and engages with the limiting frame 39 through symmetrically opened sleeve holes. The limiting frame 39 is welded to the front face of the receiving hopper 37 below the processing chamber 317 to provide guidance for the spring block 27, and then drives the front push plate 22 to slide and reset in the opposite direction through the first connecting rod 23. As the front push plate 22 resets, the rear push plate 25 resets simultaneously. Finally, the end face of the rear push plate 25 fits against the inner wall of the discharge port 315, thus sealing the discharge port 315 and preventing garbage or juice from leaking from the discharge port 315 during subsequent compression. The filter press block 13 continues to rise under the drive of the hydraulic cylinder 15. Since the partition 11 set on the top edge of the filter press block 13 is slidably inserted into the slot 322 opened on the top surface of the compression chamber 321, the filter press block 13 will synchronously drive the partition 11 to rise along the slot 322. The transmission tooth grooves 12 symmetrically opened on both sides of the front end face of the partition 11 mesh with the transmission gear 32 on the outer surface of the transmission rod 33 in the limiting component 3. The transmission rod 33 is rotated and locked on the top of the processing chamber 317, and both ends extend to the outside of the processing chamber 317. Therefore, when the partition 11 rises, it will drive the transmission gear 32 to rotate through the transmission tooth grooves 12, thereby driving the transmission rod 33. The transmission rod 33 rotates synchronously, and the winding reels 34 on the outer surfaces of both ends of the transmission rod 33 rotate with the transmission rod 33, winding and pulling the second traction rope 35 wound on the outer surface of the winding reel 34. One end of the second traction rope 35 is fixedly connected to the baffle 36, and the baffle 36 is inserted through the bottom surface of the receiving hopper 37. Therefore, when the second traction rope 35 is wound, it will drive the baffle 36 to rise in the vertical direction. After the baffle 36 rises, it separates the kitchen waste accumulated on the upper surface of the receiving hopper 37, so that the waste on the lower side of the baffle 36 is unobstructed and slides down the inclined surface of the receiving hopper 37 into the compression chamber 321 to replenish raw materials for the next compression process. When all the waste on the lower side of the baffle 36 slides into the compression chamber 321, the filter block 13 has risen to its maximum stroke. At this time, the control cabinet 31 controls the hydraulic cylinder 15 to extend its output shaft, causing the filter block 13 to descend and enter the next round of compression and dewatering process. At the same time, the descent of the filter block 13 causes the partition 11 to descend, which drives the transmission rod 33 to rotate in the opposite direction through the transmission tooth groove 12 and the transmission gear 32. The winding reel 34 releases the second traction rope 35, and the baffle 36 descends and resets under the action of gravity. The remaining waste on the upper surface of the receiving hopper 37 can continue to be added to the lower side of the baffle 36, waiting for the next feeding. Through the upper cycle, the equipment realizes alternating processing, eliminating the need for frequent manual feeding and unloading, and the operation process is seamless. After prolonged use, the filter plate 312's filter holes are easily clogged by fine particles from kitchen waste, affecting the juice filtration efficiency. At this time, the drive motor 310 can be started via the power distribution cabinet 31. The drive motor 310 is fixedly installed on the side of the processing chamber 317, directly below the power distribution cabinet 31. The output shaft of the drive motor 310 rotates, and through a transmission sprocket at one end, which is fixed to the drive motor 310's output shaft and the transmission chain, the transmission sprocket meshes with the transmission sprocket at one end of the cleaning shaft 318, driving the contents of the water collection tank 319. Multiple sets of cleaning shafts 318 rotate synchronously. The cleaning shafts 318 rotate evenly and are engaged inside the water collection tank 319 and located below the filter plate 312. The outer surface of the cleaning shafts 318 is provided with cleaning brushes that abut against the bottom surface of the filter plate 312. When the cleaning shafts 318 rotate, the cleaning brushes on the surface of the cleaning shafts 318 brush the bottom surface of the filter plate 312, remove the particulate impurities that are blocked in the filter holes, and let them fall into the bottom of the water collection tank 319. They are periodically discharged through the drain port of the water collection tank 319, effectively reducing the clogging problem of the filter plate 312 and ensuring filtration efficiency. If the filter plate 312 becomes severely clogged, and the automatic cleaning cannot remove the blockage, the power to the equipment can be turned off. The threaded rod 38, which is engaged with the middle of the limit frame 39, can be rotated. The threaded rod 38 is threadedly connected to the middle of the filter plate 312. Through the threaded transmission, the filter plate 312 is driven to slide along the slide rail on the front face of the processing chamber 317 away from the discharge port 315 until the filter plate 312 is completely exposed outside the equipment. The staff can then directly rinse, brush, or replace the surface of the filter plate 312. After clearing the blockage, the threaded rod 38 can be rotated in the opposite direction to reset the filter plate 312 and put it back into use. The maintenance operation is convenient and efficient. In summary, this equipment achieves integrated processing of household kitchen waste through the precise coordination of the filter press component 1, the feeding component 2, and the limiting component 3. It can complete the entire process of feeding, compression, dewatering, slag-liquid separation, slag discharge, and equipment reset without extensive manual intervention, effectively reducing labor costs in the processing stage and improving processing efficiency. At the same time, by recovering the slag and liquid to produce fermentation liquid and feed respectively, it realizes the resource utilization of household waste, achieves environmental protection goals, and meets the needs of large-scale, automated household kitchen waste treatment.
