Description

Technical Field

[0001] The invention relates to the technical field of garbage compression, and in particular to a scraping and pressing type kitchen waste compressor. Background Art

[0002] Garbage compression equipment can compress and reduce the volume of kitchen waste, thereby reducing the number of transportation times, transportation costs and the space required for subsequent processing. It is also conducive to sealed transportation and reduces secondary pollution. For vertical garbage compression stations, the garbage to be compressed is dumped into the compression bin at the unloading position, and the dumping process is repeated until the entire compression bin is filled. The pressure head is then lowered into the compression bin to compress the garbage, and then the garbage is dumped again until the compressed garbage fills the compression bin. Finally, the compressed garbage is transferred to an external garbage bin for transportation. When people throw away kitchen waste, most of them will pack it in a garbage bag and throw it away together. There may be water or other liquids in the garbage bag, which will cause the liquid to be squeezed out and gathered at the bottom of the bin when the garbage is compressed, accelerating the decomposition of organic matter to generate more leachate, causing damage to the garbage bin, and seepage to pollute the surrounding environment.

DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] In the description of the present invention, it should be understood that descriptions involving orientation, such as orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] In the description of the present invention, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0022] Reference Figures 1 to 10 As shown, a scraper-type kitchen waste compressor according to an embodiment of the present invention comprises: a box body 100, a scraper drive assembly 200, a tipping bucket assembly 300, a liquid extraction pipe 400, a rotating pipe drive assembly 500, and a vacuum liquid extraction assembly 600. The box body 100 is formed by welding steel and steel plates. Since it needs to withstand the pressure generated when compressing garbage, the part of the box body 100 storing garbage is preferably set to a cylindrical shape. Since other components need to be installed, the other part of the box body 100 is preferably set to a rectangular shape. The box body 100 is provided with a feed port 110 facing obliquely upward; the feed port 110 is arranged above the front end of the box body 100. The scraper drive assembly 200 is arranged above the inside of the box body 100, and is used to compress the garbage inside the box body 100; the scraper drive assembly 200 compresses the garbage in the box body 100 backward to increase the density of the garbage and compress the volume occupied by the garbage. The tipping bucket assembly 300 is connected to the front side of the box body 100, and the tipping bucket assembly 300 is used to dump the garbage in the trash can from the feed port 110 into the box body 100; since urban domestic garbage is initially collected by the trash can, it is necessary to fix the trash can and the tipping bucket assembly 300, and then use the tipping bucket assembly 300 to dump the garbage in the trash can into the feed port 110, and the feed port 110 that opens obliquely upward is conducive to the entry of garbage. Since domestic garbage usually has a high water content, garbage leachate will be generated during the compression process, and the garbage leachate needs to be collected to prevent environmental pollution. The suction pipe 400 is rotatably set at the bottom of the box body 100, and a plurality of suction holes 410 are opened on the peripheral wall of the suction pipe 400; the garbage leachate at the bottom of the box body 100 can enter the suction pipe 400 through the suction holes 410, and the garbage leachate is discharged through the suction pipe 400. The rotating tube driving assembly 500 is connected to the housing 100, and the rotating tube driving assembly 500 is used to drive the liquid extraction tube 400 to rotate; since the garbage will continue to squeeze the liquid extraction tube 400 during the compression process, the garbage may block the liquid suction hole 410, so the rotating tube driving assembly 500 is used to drive the liquid extraction tube 400 to rotate, so that the liquid suction hole 410 maintains a state of continuous movement, and the liquid suction hole 410 is not easy to be blocked, thereby improving the efficiency of discharging garbage leachate, and the vacuum liquid extraction assembly 600 is connected to the liquid extraction tube 400 through a rotary joint 401. The specific structure of the rotary joint 401 is the prior art, so it will not be described in detail. The vacuum liquid extraction assembly 600 is used to extract the fluid in the liquid extraction tube 400. The garbage leachate in the prior art is discharged naturally by gravity, while the vacuum liquid extraction assembly 600 generates negative pressure in the liquid extraction tube 400, so that the liquid extraction tube 400 can discharge the garbage leachate faster and reduce the water content of the garbage after compression.

[0023] Reference Figures 1 to 7As shown, it can be understood that the scraper drive assembly 200 includes a scraper bracket 210 and a scraper plate 220. The scraper bracket 210 is horizontally slidably mounted on the box body 100, and two guide rails extending forward and backward are provided on the box body 100. The scraper bracket 210 is slidably mounted on the guide rails on both sides. The guide rails guide the scraper bracket 210. The box body 100 is provided with a first hydraulic drive member 120, and the first hydraulic drive member 120 uses a hydraulic cylinder. The first hydraulic drive member 120 is symmetrically provided with two to smoothly push the scraper bracket 210 to move. The first hydraulic drive member 120 is used to drive the scraper bracket 210 to move in the direction close to the feed port 110 and away from the feed port 110. The scraper plate 220 is rotatably mounted on the scraper bracket 210. The scraper bracket 210 is provided with a second hydraulic drive member 211, and the second hydraulic drive member 211 is used to drive the scraper plate 220 to reciprocate and rotate. When the garbage enters the box 100 from the feed inlet 110, the scraper bracket 210 is located far away from the feed inlet 110 to facilitate the garbage to enter the box 100. When compressing the garbage, the first hydraulic drive 120 first drives the scraper bracket 210 to move to a position close to the feed inlet 110, and then the second hydraulic drive 211 drives the scraper plate 220 to rotate downward to compress the garbage. Then the first hydraulic drive 120 drives the scraper bracket 210 to move to a position far away from the feed inlet 110. During this process, the garbage is compressed backward. Then the second hydraulic drive 211 drives the scraper plate 220 to rotate upward. Then the next batch of garbage is poured into the feed inlet 110, and the cycle works in this way until the internal space of the box 100 is filled with compressed garbage.

[0024] Reference Figures 1 to 10 As shown, it can be understood that the box 100 is connected to a third hydraulic drive member 130, and the third hydraulic drive member 130 is a hydraulic cylinder or a hydraulic motor. A cover plate 700 is rotatably mounted on the box 100, and the third hydraulic drive member 130 is used to drive the cover plate 700 to switch between a first position of closing the feed port 110 and a second position of opening the feed port 110. When garbage is continuously poured into the feed port 110, the third hydraulic drive member 130 drives the cover plate 700 to move to the second position, so that the cover plate 700 does not affect the garbage pouring into the feed port 110. When the box 100 is full of garbage and needs to be transported, the third hydraulic drive member 130 drives the cover plate 700 to move to the first position, and the cover plate 700 closes the feed port 110 to prevent rainwater from the outside from entering the box 100, and also prevent the garbage and odor in the box 100 from polluting the environment during transportation.

[0025] It can be foreseen that the hydraulic power source is not connected to the box 100, and only the interface of the hydraulic oil pipe is reserved outside the box 100. The external hydraulic power source is connected to the first hydraulic drive component 120, the second hydraulic drive component 211, and the third hydraulic drive component 130 through the hydraulic oil pipe. The hydraulic power source and the box 100 are set separately to reduce the weight of the box 100, which is beneficial to the transportation of the box 100. Multiple boxes 100 can be matched with the same hydraulic power source, which is beneficial to reduce manufacturing costs.

[0026] Reference Figures 1 to 8 As shown, it can be understood that the box 100 is provided with a locking device 800, which includes a locking hydraulic rod and a lock buckle. The lock buckle is rotatably mounted on the box 100, and the locking hydraulic rod can drive the lock buckle to abut against the cover plate 700 located at the first position, so as to fix the cover plate 700 at the first position. The locking hydraulic rod can also drive the lock buckle to separate from the cover plate 700 located at the first position. After the lock buckle is separated from the cover plate 700, the cover plate 700 can move from the first position to the second position. When the box 100 is filled with garbage for transportation, the locking device 800 fixes the cover plate 700 at the first position to prevent the garbage and odor in the box 100 from polluting the environment during transportation.

[0027] Reference Figures 1 to 10 As shown, it can be understood that the tipping bucket assembly 300 includes a flip frame 310 and a flip drive assembly 320. The flip frame 310 is used to fix the trash can. The flip drive assembly 320 is connected to the frame. The flip frame 310 is a prior art, and the specific structure and installation method are not described in detail. The flip drive assembly 320 is used to flip the trash can fixed on the flip frame 310 to the feed port 110. The flip drive assembly 320 uses a hydraulic cylinder or an electric motor. The left and right ends of the flip frame 310 are rotatably installed with connecting cantilevers 311. The connecting cantilever 311 extends forward, and the rotation axis of the connecting cantilever 311 extends in the vertical direction. A hook is set at the front end of the connecting cantilever 311. The connecting cantilever 311 cooperates with the protrusion on the side of the trash can to fix the trash can. The flip frame 310 is connected to an adjustment assembly 330 for adjusting the rotation angle of the connecting cantilever 311. Since trash cans have various specifications, in the prior art, when encountering a trash can that cannot be adapted, it is necessary to manually pour the trash in the trash can into the feed port 110, which is labor-intensive. Therefore, in this solution, the angle of the connecting cantilever 311 is changed by adjusting the component 330, thereby changing the distance between the front ends of the two connecting cantilever 311, so that the connecting cantilever 311 can fix trash cans of various sizes. The adaptability to trash cans of different sizes is improved, and the labor intensity of the operator is effectively reduced.

[0028] Reference Figures 1 to 10As shown, it can be understood that the adjustment assembly 330 includes an adjustment screw 331 and an elastic member 332. The adjustment screw 331 is a hexagonal bolt. A threaded hole is provided on the connecting cantilever 311. The position of the threaded hole matches the position of the flip frame 310. The extension direction of the threaded hole is perpendicular to the rotation axis direction of the connecting cantilever 311. The adjustment screw 331 is threadedly connected in the threaded hole. By rotating the adjustment screw 331, the length of the adjustment screw 331 extending out of the threaded hole can be changed. The elastic member 332 is a tension spring. One end of the elastic member 332 is connected to the connecting cantilever 311, and the other end is connected to the flip frame 310. The elastic member 332 is used to drive the connecting cantilever 311 to rotate and make the adjustment screw 331 and the flip frame 310 tightly contact. When the adjustment screw 331 rotates clockwise, the length of the adjustment screw 331 extending out of the threaded hole becomes longer, thereby pushing the connecting cantilever 311 to move in a direction close to each other and the elastic member 332 is stretched. When the adjusting screw 331 rotates counterclockwise, the length of the adjusting screw 331 extending out of the threaded hole becomes shorter, and the elastic member 332 is reset, thereby pulling the connecting cantilever arms 311 to move away from each other. The operator can conveniently adjust the distance between the two connecting cantilever arms 311 by using a wrench.

[0029] Reference Figures 1 to 5 As shown, it can be understood that a discharge door 140 is provided on the side of the box body 100 away from the feed port 110. After the box body 100 is filled with garbage, the box body 100 needs to be transported to the landfill as a whole. After the box body 100 is transferred to the landfill, the discharge door 140 on the rear side of the box body 100 is opened, and the garbage in the box body 100 can be easily poured out.

[0030] Reference Figures 1 to 10 As shown, it can be understood that a groove 150 is provided at the bottom of the box body 100, and the extension direction of the groove 150 is the same as the extension direction of the liquid extraction pipe 400. The liquid extraction pipe 400 is partially located in the groove 150, and a scraper 160 is provided on the side wall of the groove 150, and the scraper 160 is welded to the side wall of the groove 150. When the liquid extraction pipe 400 rotates, the scraper 160 can scrape off the garbage on the outer surface of the liquid extraction pipe 400. The scraper 160 can also prevent garbage from entering the groove 150. The distance between the scraper 160 and the outer surface of the liquid extraction pipe 400 is less than 2mm to prevent garbage from entering the groove 150, but it can allow garbage leachate to enter the groove 150. The groove 150 plays the role of accommodating and collecting garbage leachate. When the vacuum liquid extraction assembly 600 is not running, the groove 150 can collect a certain amount of garbage leachate, which plays a buffering role.

[0031] Reference Figures 1 to 10As shown, it can be understood that the rotating tube drive assembly 500 uses a combination of a motor and a reducer or a hydraulic motor. The rotating tube drive assembly 500 preferably uses a hydraulic motor, because the first hydraulic drive member 120, the second hydraulic drive member 211, and the third hydraulic drive member 130 all use high-pressure hydraulic oil as a power source, so the use of a hydraulic motor can simplify the control system and the connection method. The hydraulic motor also has the advantage of large torque, which can prevent garbage from getting stuck in the liquid extraction tube 400. A driving gear 510 is arranged on the output shaft of the rotating tube drive assembly 500, and a driven gear ring 420 is arranged on the outer peripheral wall of the liquid extraction tube 400. The driven gear ring 420 is located outside the box 100, and the driven gear ring 420 is meshed with the driving gear 510. The rotating tube drive assembly 500 drives the driving gear 510, and the driving gear 510 drives the liquid extraction tube 400 to rotate through the driven gear ring 420. Compared with the use of belt drive, the use of gear transmission can transmit a larger torque.

[0032] Reference Figures 1 to 10 As shown, it can be understood that the vacuum liquid extraction component 600 includes a vacuum pump 610 and a rotating drum 620. The rotating drum 620 is provided with an air pipe 621 and a liquid pipe 622. The height of the lower end of the liquid pipe 622 is lower than the height of the lower end of the air pipe 621. The height of the lower end of the air pipe 621 should be higher than the maximum liquid level in the rotating drum 620 to prevent the leachate in the rotating drum 620 from entering the vacuum pump 610. The height of the rotating drum 620 is less than or equal to the height of the bottom of the box 100 to prevent the garbage leachate in the rotating drum 620 from flowing back into the bottom of the box 100. The air pipe 621 is connected to the vacuum pump 610, and the liquid pipe 622 is connected to the rotary joint 401. The vacuum pump 610 extracts the gas in the rotating drum 620 through the air pipe 621, forming a negative pressure in the rotating drum 620, and then the garbage leachate enters the liquid pipe 622 from the liquid extraction pipe 400 under the action of the external atmospheric pressure, and then enters the rotating drum 620. The transfer cylinder 620 serves to separate gas and liquid, and prevents damage to the vacuum pump 610. A liquid outlet valve is connected to the lower end of the transfer cylinder 620. When the liquid level in the transfer cylinder 620 reaches a preset height, the vacuum pump 610 is stopped, and the liquid outlet valve is opened to discharge the garbage leachate in the transfer cylinder 620. After the garbage leachate in the transfer cylinder 620 is completely discharged, the liquid outlet valve is closed, and the vacuum pump 610 is started again.

[0033] It is foreseeable that in some other embodiments of the present invention, the outer side of the housing 100 is bolted with a fixed block 900, and the fixed block 900 is provided with a rotary sealing end cap 910, which is used to seal the opening of the liquid extraction tube 400 away from the rotating tube drive assembly 500. The rotary sealing end cap 910 can realize the rotary sealing of the liquid extraction tube 400. The inner side of the rotary sealing end cap 910 is fixedly connected with a scraper shaft 920, and the scraper shaft 920 extends into the liquid extraction tube 400, and the scraper shaft 920 is coaxially arranged with the liquid extraction tube 400. A plurality of semi-spiral plates 930 are arranged at intervals above the scraper shaft 920, and the spacing between the semi-spiral plates 930 and the inner wall of the liquid extraction tube 400 is less than 1 mm. Since the scraper shaft 920 is fixed, when the liquid extraction tube 400 rotates, the semi-spiral plates 930 can clean the inner wall of the liquid extraction tube 400, further reducing the probability of clogging of the suction hole 410. No half spiral plate 930 is provided under the scraper shaft 920 to allow the garbage leachate to flow freely. It is foreseeable that when the liquid extraction pipe 400 is completely blocked, the fixing block 900 can be disassembled, and the scraper shaft 920 can be rotated 180 degrees, so that the garbage blocked in the liquid extraction pipe 400 enters between the adjacent half spiral plates 930, and then the scraper shaft 920 is pulled out to take out the blocked garbage, and the liquid extraction pipe 400 can be cleaned. After the scraper shaft 920 is rinsed clean with a high-pressure water gun, the scraper shaft 920 can be inserted into the liquid extraction pipe 400.

[0034] Steps: Step 1: The locking hydraulic rod can also drive the lock to separate from the cover plate 700 at the first position, and the third hydraulic driving member 130 drives the cover plate 700 to move from the first position to the second position, so that the cover plate 700 does not affect the garbage pouring into the feed port 110. Rotate the adjustment screw 331 to change the distance between the front sides of the two connecting cantilevers 311; Step 2: Place the trash can between the two connecting cantilevers 311 and fix it. The flip drive assembly 320 drives the trash can and the flip frame 310 to move to the feed inlet 110 and pour the trash into the feed inlet 110. Then the flip drive assembly 320 drives the trash can to move until the trash can contacts the ground, and then replace the trash can. Step 3: The first hydraulic drive 120 first drives the scraper bracket 210 to move to a position close to the feed inlet 110, and then the second hydraulic drive 211 drives the scraper plate 220 to rotate downward to compress the garbage, and then the first hydraulic drive 120 drives the scraper bracket 210 to move to a position away from the feed inlet 110. During this process, the garbage is compressed backward. Then the second hydraulic drive 211 drives the scraper plate 220 to rotate upward; Step 4: The rotating tube driving assembly 500 drives the liquid extraction tube 400 to rotate. During the rotation of the liquid extraction tube 400, the scraper 160 scrapes off the garbage on the outside of the liquid extraction tube 400, and the semi-spiral plate 930 scrapes off the garbage on the inside of the liquid extraction tube 400 to prevent the suction hole 410 from being blocked. The vacuum pump 610 extracts the gas in the rotating cylinder 620 through the air pipe 621, forming a negative pressure in the rotating cylinder 620, and then the garbage leachate enters the liquid pipe 622 from the liquid extraction tube 400 under the action of the external atmospheric pressure, and then enters the rotating cylinder 620. The rotating cylinder 620 plays the role of gas-liquid separation to prevent damage to the vacuum pump 610. The lower end of the rotating cylinder 620 is connected to a liquid outlet valve. When the liquid level in the rotating cylinder 620 reaches a preset height, the vacuum pump 610 is stopped, and the liquid outlet valve is opened to discharge the garbage leachate in the rotating cylinder 620. After the leachate in the transfer drum 620 is completely discharged, the liquid outlet valve is closed and the vacuum pump 610 is started again; Step 5: Repeat steps 2 and 3 until the internal space of the box 100 is filled with compressed garbage; Step six: transport the box 100 to a landfill, open the discharge door 140, and pour out the compressed garbage.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
