Description

Technical Field

[0001] This utility model relates to the field of waste compression technology, specifically to a self-cleaning system and a waste compression station equipped with the system. Background Technology

[0002] A waste compression station is a facility that compresses waste. This process significantly reduces the volume of waste, thereby lowering the costs of waste transportation and landfill.

[0003] According to patent publication number CN213169732U, published on 2021-05-11, a side-moving vertical compression garbage station is disclosed, comprising: a compression box for storing garbage; a pit for placing the compression box; a vertical pressure assembly for compressing the garbage in the compression box; a drive assembly for driving the vertical pressure assembly to move above the compression box; a lifting assembly for driving the compression box to move vertically; a pushing assembly for pushing out the garbage in the compression box; and an auxiliary suspension assembly for assisting in hooking and securing the lifted compression box.

[0004] In the existing technologies, including the aforementioned patents, most common garbage compression stations currently use a vertical or side-push method to compress garbage. During the compression process, some garbage will produce sewage or dirt that adheres to the inner wall of the compression chamber. Generally, staff need to regularly clean the garbage compression station with high-pressure water guns. However, high-pressure water gun cleaning wastes a lot of water. Furthermore, for some side-push garbage compression stations, which are set up horizontally, sewage tends to accumulate inside after cleaning. If this sewage is not discharged, it can easily become smelly or corrode the inner wall of the compression chamber, thus affecting the use of the equipment. Utility Model Content

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a self-cleaning system and a waste compression station equipped with the system include a circular compression pipe 1 that is inclined downward at a predetermined angle. A support member 2 is fixedly installed on the outer wall of the circular compression pipe 1. A feed hopper 21 communicating with the inside of the circular compression pipe 1 is fixedly installed on the support member 2. A cover 3 hinged on the support member 2 is movably disposed at the end of the circular compression pipe 1. A compression plate 42 is movably disposed inside the circular compression pipe 1 along its axial direction. A water box 8 is disposed on the side of the compression plate 42 opposite to the cover 3, and a water spray nozzle 82 is opened on the outer wall of the water box 8 facing the inner wall of the circular compression pipe 1. Waste is fed into the circular compression pipe 1 through the feed hopper 21, and then compressed by the compression plate 42 moving towards the cover 3. After the waste is compressed, the cover 3 is opened and the compression plate 42 is used again to push the compressed waste out of the circular compression pipe 1. When it is necessary to clean the inside of the circular compression pipe 1, water is pumped from the water box 8 and sprayed onto the inner wall of the circular compression pipe 1 through multiple spray nozzles 82. At this time, the compression plate 42 moves to perform faster and more comprehensive cleaning, and the wastewater generated by cleaning is discharged along the downward-sloping circular compression pipe 1, thereby avoiding water accumulation in the circular compression pipe 1.

[0026] Specifically, the predetermined angle is a downward tilt of 1-5°.

[0027] As a further technical solution provided by this utility model, it includes a platform 25 for fixing the circular compression tube 1 and the support member 2, and a support frame 24 fixedly installed on the support member 2. The first hydraulic cylinder 4 and the compression plate 42 fixedly installed on the platform 25 are fixedly connected.

[0028] Specifically, the first hydraulic cylinder 4 pushes the compression plate 42 to compress the waste, and the movement of the compression plate 42 pushed by the first hydraulic cylinder 4 can also cooperate with the water spray nozzle 82 to achieve self-cleaning of the circular compression pipe 1.

[0029] Furthermore, mounting plates 22 are symmetrically fixedly installed on the top of the support member 2, and a second hydraulic cylinder 35 is hinged between the two mounting plates 22. Extension rods 33 are symmetrically arranged on the cover 3, and the output end of the second hydraulic cylinder 35 is hinged to the support rod 34 fixedly installed between the two extension rods 33.

[0030] Specifically, the second hydraulic cylinder 35 pushes the support rod 34 to cause the cover 3 to flip down and close the port of the circular compression tube 1, while the second hydraulic cylinder 35 pulls the support rod 34 to cause the cover 3 to flip up and open the port of the circular compression tube 1.

[0031] Furthermore, the support member 2 is provided with a positioning block 23, and the positioning block 23 is provided with a slot 26. The protrusion 31 provided on the cover 3 is movably disposed in the slot 26. The third hydraulic cylinder 5 is fixedly installed in the positioning block 23, and the locking rod 51 fixedly installed at the output end of the third hydraulic cylinder 5 is movably disposed in the insertion hole 32 opened on the protrusion 31.

[0032] Specifically, when the cover 3 is flipped down to close the port of the circular compression tube 1, the protrusion 31 is located in the slot 26. Then, the third hydraulic cylinder 5 pushes the locking rod 51 into the insertion hole 32 opened on the protrusion 31, thereby locking the cover 3 with the locking rod 51, thus preventing the cover 3 from being pushed open when the compression plate 42 compresses the garbage.

[0033] Furthermore, the bottom of the support member 2 and the platform 25 are provided with a cleaning groove 12 and a drain hole 11.

[0034] Specifically, the drain hole 11 allows some of the waste liquid generated during garbage compression to be discharged into the circular compression pipe 1, while the cleaning tank 12 allows for observation and cleaning of the inner wall of the circular compression pipe 1.

[0035] Furthermore, a connecting column 41 is fixedly installed between the first hydraulic cylinder 4 and the compression plate 42. A sealing box 7 is fixedly installed on the outer wall of the connecting column 41, and the sealing box 7 and the water box 8 are fitted together to form a water storage cavity 71. A water guide 6 is fixedly installed on the outer wall of the connecting column 41, and a flexible water pipe 43 is fixedly connected to the water guide 6. Multiple water guide grooves 44 are opened inside the connecting column 41, with both ends connected to the water guide 6 and the water storage cavity 71 respectively.

[0036] Specifically, one end of the flexible water pipe 43 is connected to a water source. After water is passed through the flexible water pipe 43, water is pumped into the water guide 6. The water in the water guide 6 flows along the water guide groove 44 to the water storage chamber 71. Then, the water in the water storage chamber 71 flows to multiple water spray nozzles 82 to perform water spraying to clean the inner wall of the circular compression pipe 1.

[0037] Furthermore, multiple elastic scrapers 85 are fixedly installed on the outer wall of the water box 8, the water box 8 is rotatably mounted on the compression plate 42, and a paddle 81 is fixedly installed inside the water box 8, with the water guide channel 44 located at the port of the water storage chamber 71 facing the paddle 81.

[0038] Specifically, when water is sprayed from the water guide trough 44 at the port of the water storage chamber 71, the water flow impacts the paddle 81, thereby driving the water box 8 to rotate. When the water box 8 rotates, multiple elastic scrapers 85 fixedly installed on the outer wall of the water box 8 are used to scrape and clean the inner wall of the circular compression pipe 1.

[0039] Furthermore, a first rubber pad 72 is fixedly installed on the outer wall of the sealing box 7, and a plurality of first perforations 73 located on one side of the first rubber pad 72 are opened on the outer wall of the sealing box 7. An annular rubber flap 74 fixedly installed on the outer wall of the sealing box 7 is attached to the first rubber pad 72, and the annular rubber flap 74 is movably disposed on the inner wall of the circular compression tube 1.

[0040] Specifically, when water is pumped into the water storage chamber 71, the water pressure inside the water storage chamber 71 increases, such as... Figure 4 As shown, water pressure causes the first rubber pad 72 to expand and push the annular rubber flap 74 outward relative to the sealing box 7. At this time, the side of the annular rubber flap 74 is used to scrape the inner wall of the circular compression tube 1, thereby cleaning the inner wall of the circular compression tube 1. At the same time, the annular rubber flap 74 adheres to the circular compression tube 1 and works with the sealing box 7 to provide a certain isolation for the circular compression tube 1. As a result, the wastewater generated by the spray nozzle 82 rinsing the circular compression tube 1 is scraped by the annular rubber flap 74 and gradually moves with the annular rubber flap 74 to push out of the circular compression tube 1, thereby reducing the accumulation of wastewater in the circular compression tube 1.

[0041] Furthermore, a second rubber pad 84 is fixedly installed on the outer wall of the water box 8. A water guide hole 83 is opened on the water box 8 on one side of the second rubber pad 84, and an elastic scraper 85 is movably disposed on the second rubber pad 84, with the port of the spray nozzle 82 facing the elastic scraper 85.

[0042] Specifically, when water is pumped into the water storage chamber 71, the water pressure inside the water storage chamber 71 increases, such as... Figure 4 As shown, water pressure causes the second rubber pad 84 to expand and push the elastic scraper 85 outward relative to the water box 8. At this time, the elastic scraper 85 adheres to the inner wall of the circular compression tube 1, and the water box 8 rotates to clean the inner wall of the circular compression tube 1 using the elastic scraper 85. Similarly, when the water pressure in the water storage chamber 71 decreases, the first rubber pad 72 and the second rubber pad 84 recover to stop pushing the annular rubber flap 74 and the elastic scraper 85 respectively. At this time, the annular rubber flap 74 and the elastic scraper 85 recover their deformation and detach from the inner wall of the circular compression tube 1, thereby avoiding excessive friction on the annular rubber flap 74 and the elastic scraper 85 during normal waste compression, which affects their service life. The elastic scraper 85 can be made of elastic stainless steel plate. When the spray nozzle 82 is directed towards the elastic scraper 85, i.e., when the spray nozzle 82 rinses the circular compression tube 1, the splashed water will wash away the waste scraped by the annular rubber flap 74, thus making it easier for the annular rubber flap 74 to better scrape the waste attached to the inner wall of the circular compression tube 1.

[0043] Working principle: Waste is fed into the circular compression pipe 1 through the feed hopper 21. Then, the first hydraulic cylinder 4 pushes the compression plate 42 towards the cover 3 to compress the waste. After compression, the second hydraulic cylinder 35 pulls the cover 3 to open the circular compression pipe 1. At this time, the compression plate 42 again pushes the compressed waste out of the circular compression pipe 1. When cleaning is required inside the circular compression pipe 1, water is pumped from the water storage chamber 71. This increases the water pressure in the water storage chamber 71. Figure 4 As shown, water pressure causes the second rubber pad 84 to expand and push the elastic scraper 85 outward relative to the water box 8. At this time, the elastic scraper 85 adheres to the inner wall of the circular compression tube 1, and the water box 8 rotates to clean the inner wall of the circular compression tube 1 using the elastic scraper 85. At the same time, the first rubber pad 72 expands and pushes the annular rubber flap 74 outward relative to the sealing box 7. At this time, the side of the annular rubber flap 74 is used to scrape the inner wall of the circular compression tube 1, thereby cleaning the inner wall of the circular compression tube 1. At the same time, the annular rubber flap 74 adheres to the circular compression tube 1 and works with the sealing box 7 to provide a certain degree of separation for the circular compression tube 1. This allows the wastewater generated by the spray nozzle 82 rinsing the circular compression tube 1 to be scraped by the annular rubber flap 74 and gradually moved with the annular rubber flap 74 to push out of the circular compression tube 1, thereby reducing the accumulation of wastewater in the circular compression tube 1.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
