Background Art

[0002] At present, with the development of domestic society and the improvement of people's living standards, as well as the gradual improvement of urban planning and construction, the scale of cities has gradually grown. In order to solve the housing problem, more and more high-rise residential communities are being built in cities, and the population density of communities is also getting higher and higher. The contradiction between the placement and collection of residential domestic waste is becoming more and more prominent. Domestic domestic waste is mainly composed of kitchen waste, which is the main source of waste liquid and harmful gases;

[0003] Chinese invention patent publication number CN113184421B discloses a "vacuum pipeline type food waste collection and transportation device, comprising a delivery system for delivering waste, a gas-solid separator for separating food waste, a gas treatment system for treating harmful gases, and a collection system for collecting and transporting food waste. The collection system comprises a food waste collection box, which is mounted on a carriage guide rail via carriage wheels. The carriage guide rail is provided with a weighing mechanism, which includes a top cover plate for supporting the carriage wheels, a hydraulic weight detection mechanism, and a hydraulic pressure sensor. The weighing mechanism detects whether the food waste collection box is full by detecting the hydraulic pressure value, and stops loading via an electronic control system. The collection and transportation device provided by this invention realizes the transportation of food waste."

[0004] The above patent has the following defects: For example, the lack of a crushing function, kitchen waste usually contains various food residues, such as vegetables, fruits, meat, bones, etc., and the size, shape and texture of these wastes vary. In the absence of crushing equipment, larger garbage chunks may clog the pipes, resulting in reduced waste treatment efficiency. In addition, since the garbage is not effectively crushed, the flow resistance in the pipes increases, requiring more time and energy to transport the garbage. In summary, the lack of crushing equipment in the kitchen waste pipes will lead to low processing efficiency, easy blockage of the pipes, affect the subsequent processing process, increase transportation costs, and be unfavorable for resource recycling.

[0005] Therefore, it is urgent to improve the vacuum kitchen waste pipeline to solve the above-mentioned problems. Summary of the Invention

[0023] Another technical problem to be solved by the present invention is to provide a control method for collecting and transporting kitchen waste in a vacuum pipeline, comprising the following steps:

[0024] 1) Material delivery: The kitchen waste is put into the pipeline through the indoor and commercial delivery ports. The vacuum space formed by the energy storage tank 1 and the material storage tank 1 collects the kitchen waste in the delivery port, and the kitchen waste is crushed by the crushing equipment;

[0025] 2) Material storage: After the liquid level sensor in the storage tank 1 detects that the material has reached the set position, the vacuum pump creates a vacuum space between the energy storage tank 2 and the material storage tank 3 to collect the kitchen waste in the storage tank 1 and store it in the storage tank 2;

[0026] 3) Discharge: When the liquid level sensor in the second storage tank detects that the liquid level has reached the set value, the discharge group will transport the kitchen waste in the second storage tank to the discharge interface or connect it to the next process;

[0027] 4) Treatment: The kitchen waste enters the dehydrator for dehydration. The dehydrated residue enters the degradation machine for biodegradation. The dehydrated wastewater enters the oil-water separation device through the sewage extraction device. At the same time, the residue enters the degradation machine for degradation into organic fertilizer. The oil-water separation device separates the oil and water. The waste oil can be recycled, and the wastewater is connected to the municipal sewage treatment system.

[0028] In addition, the vacuum pump replenishes the vacuum degree of energy storage tank 1, energy storage tank 2 and pipelines to ensure the suction capacity of the system. The gas discharged by the vacuum pump is treated by the exhaust gas treatment device and then discharged in compliance with the standards.

[0029] The present invention has at least the following beneficial effects:

[0030] 1. The control method for the collection and transportation of kitchen waste in the vacuum pipeline controls the processing module through the central control room to collect and process the kitchen waste in the storage module. The system can cover a large area without the need for dispersed collection systems. It is energy-saving and environmentally friendly, and provides a solution for on-site treatment of kitchen waste and a solution for closed docking with the existing transfer system. At the same time, kitchen waste can be converted into organic fertilizer on-site to achieve resource recycling. The exhaust gas generated during operation is discharged after passing through a special treatment device and meets the discharge standards without polluting the environment. In addition, the kitchen wastewater is separated into oil and water to recover grease, and the wastewater is connected to a special wastewater treatment system for treatment and then discharged after meeting the standards, thereby maximizing resource utilization while protecting environmental hygiene.

[0031] 2. The vacuum pipeline kitchen waste collection, transportation and treatment system crushes the kitchen waste in the delivery port. The kitchen waste entering the connecting pipe is crushed by the transmission cooperation of the drive motor and two sets of crushing rollers. When the crushing rollers rotate, the transmission cooperation between the transmission wheel and the transmission belt drives the rotating shaft to start the piston structure. When the rotating shaft rotates, the swing arm drives the sphere to rotate. When the sphere rotates, it will produce centrifugal outward expansion, thereby driving the sleeve to move inward. When the sleeve moves, it squeezes the push arm to move the piston block downward. When the piston block moves downward under the action of squeezing, it will exert additional pressure on the garbage. This pressure helps the crusher to crush the garbage more effectively. At the same time, during the movement of the piston block, its edge will rub against the inner wall of the pipe, which helps to remove residue or grease attached to the inner wall of the pipe, thereby cleaning the inner wall of the pipe.

[0032] 3. When the vacuum pipeline kitchen waste collection, transportation and treatment system is in use, the length of the swing arm is adjusted, and then the adjusted swing arm is fixed by a locking structure, thereby adjusting the centrifugal force generated by the sphere during rotation. The magnitude of the centrifugal force directly affects the adjustment effect of the piston block, thereby achieving the advantage of flexible adjustment, so that the system can adapt to different types of kitchen waste and treatment needs.

[0033] 4. When the vacuum pipeline kitchen waste collection and treatment system is in use, the piston block reciprocates inside the pipeline, which helps to remove residues or grease attached to the inner wall of the pipeline, thereby cleaning the inner wall of the pipeline. At the same time, the nozzle is used to spray an appropriate amount of water or other detergent into the pipeline to further help flush the inner wall of the pipeline and enhance the cleaning effect.

[0034] 5. In this vacuum pipeline kitchen waste collection and treatment system, when the two connecting sleeves move relative to each other, the two pressure rods will move into the pressure sleeve and squeeze the pressure sensor to close the rotating shaft. At this time, the piston block returns to its original state through the reset spring, which is convenient for controlling the reciprocating movement of the piston block.

[0035] 6. In addition to solving the problems existing in commercial and centralized disposal points, the most important thing about this vacuum pipeline kitchen waste collection and treatment system is that it is difficult for residents of high-rise and super-high-rise buildings to dispose of kitchen waste under the garbage classification policy. The kitchen waste disposal port is directly set on the cabinet work surface of the resident's kitchen. Kitchen waste can be directly put into the pipeline collection system through the disposal port at any time without the need to bag and then unbag it, which provides great convenience to residents and solves the odor pollution of conventional collection methods.

[0048] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0049] like Figure 1 and Figure 2As shown, the vacuum pipeline kitchen waste collection, transportation and treatment system provided in this embodiment includes a feed port 1, a storage module, a processing module, and a central control room 10. The storage module includes storage tank 1 2, energy storage tank 1 3, material storage tank 2 4, and energy storage tank 2 6. The processing module includes a vacuum pump 5, an exhaust gas treatment device 7, a discharge / anti-solidification device 9, a degradation machine 11, a dehydrator 12, a waste extraction device 13, an oil-water separator 14, and a discharge interface 15. The feed port 1 includes an indoor feed port 1-1 and a commercial feed port 1-2. A valve group 16 is provided between the feed port 1 and the storage module. The valve group 16 includes an electric air inlet valve 16-1 and a pneumatic gate valve 16-2.

[0050] Specifically, the processing module and the central control room 10 are connected by signals through control elements. All control elements are connected to the central control room 10, which can realize automatic control or manual control operation of the system. The discharge / anti-coagulation equipment 9 is a discharge group 8, and the discharge group 8 is composed of a shredder pump 8-1 and a discharge pump 8-2. When in use, the delivery port 1 can be set in the resident's kitchen, and the kitchen waste can be directly put into the delivery port 1 without putting it in a garbage bag and then taking it to a designated place for delivery, which is convenient and fast; and the delivery port 1 is provided with a weighing and capacity limiting device, which can limit excessive kitchen waste from entering the pipeline and prevent the pipe section from being blocked; the amount of garbage delivered can be weighed in real time, and the weight data can be transmitted to the background in real time, which is convenient for the operator to conduct data statistics.

[0051] It should be noted that there are no restrictions on the number of residents, thus enabling the transportation of kitchen waste from high-rise and super-high-rise buildings. The discharge pump 8-2 circulates the material in the storage tank 2 4 through a loop to prevent the kitchen waste from solidifying. The storage tank 2 4 has an automatic anti-solidification device to maintain the fluidity of the kitchen waste, ensuring normal collection and transportation, and can be used in low-temperature environments. In addition, the entire collection and transportation pipeline from the user-side kitchen waste inlet is under negative pressure, rather than relying on gravity, ensuring complete collection and transportation without pipeline residue.

[0052] In order to avoid the blockage of the vacuum pipe, in this embodiment, Figure 3-Figure 9As shown, a crushing device 17 is provided in the feeding port 1; the crushing device 17 includes a connecting pipe 18, a crusher 19 installed in the connecting pipe 18, and a piston structure 21 provided at the top of the connecting pipe 18; the crusher 19 includes a driving motor 1901 fixedly installed on the outer surface of the connecting pipe 18, two crushing rollers 1902 rotatably installed inside the connecting pipe 18, and two transmission gears 1903 fixedly installed at the same end of the two crushing rollers 1902 and meshing with each other; the piston structure 21 includes a rotating shaft 2101 provided above the top of the connecting pipe 18, a piston block 2102 reciprocatingly provided inside the connecting pipe 18, a sleeve 2103 and a sliding sleeve 2107 sleeved on the outer surface of the rotating shaft 2101, a mounting ring 2104 fixedly connected to one end of the sleeve 2103, and a hinged A swing arm 2105 is installed on the outer surface of the mounting ring 2104 and a sphere 2106 is fixedly installed on the end of the swing arm 2105. A connecting sleeve 2108 is rotatably installed on the outer surface of the sleeve 2107, and a connecting rod 2109 is hingedly installed between the outer surface of the sleeve 2107 and the swing arm 2105. A return spring 2111 is rotatably installed between the sleeve 2107 and the mounting ring 2104. A push arm 2110 is hingedly installed between the connecting sleeve 2108 and the piston block 2102. The swing arm 2105 consists of a first connecting arm 21051, a second connecting arm 21052 and an extension arm 21053. One end of the extension arm 21053 is welded and fixed to the end of the second connecting arm 21052, and the other end of the extension arm 21053 is matched with the internal thread of the first connecting arm 21051.

[0053] In this embodiment, a removable mounting sleeve 2116 is provided on the first connecting arm 21051, and a locking structure 2117 is provided on the mounting sleeve 2116. The locking structure 2117 includes a mounting seat 21171 fixedly mounted on the outer surface of the mounting sleeve 2116, a pressing handle 21172 elastically hingedly mounted on the mounting seat 21171, and a clamping block 21173 fixedly connected to the end of the pressing handle 21172 and pluggably engaged with the interior of the first connecting arm 21051. A plurality of locking holes 21174 corresponding to the clamping blocks 21173 are defined within the first connecting arm 21051. The clamping blocks 21173 are pluggably connected to the locking holes 21174. A torsion spring is provided at the connection between the pressing handle 21172 and the mounting seat 21171. The mounting sleeve 2116 is fixed to the outer surface of the second connecting arm 21052 via bolts. By adjusting the length of swing arm 2105 and securing it with locking structure 2117, the centrifugal force generated by the rotating sphere 2106 can be adjusted. The magnitude of this centrifugal force directly affects the adjustment effect of piston block 2102, achieving the advantage of flexible adjustment, allowing the system to adapt to different types of food waste and processing requirements. Furthermore, a positioning shaft, which plugs into mounting base 21171 and is mounted within push handle 21172, ensures high-speed rotation of swing arm 2105.

[0054] Specifically, two butt joints are mounted on the outer surface of the top end of the connecting pipe 18. A piston block 2102 is positioned above the two butt joints, while a crushing roller 1902 is positioned below the two butt joints. The outer surface of the piston block 2102 abuts the inner wall of the connecting pipe 18. The butt joints can communicate with the pipe of the delivery port 1. Two symmetrically distributed mounting brackets 20 are welded to the outer surface of the top end of the connecting pipe 18, and the bearing of the rotating shaft 2101 is mounted between the two mounting brackets 20.

[0055] In this embodiment, the interiors of sleeve 2103, mounting ring 2104, sliding sleeve 2107, and connecting sleeve 2108 are all hollow. A positioning rod is installed within sleeve 2103 and plugs into rotating shaft 2101. The plug-in engagement of the positioning rod with rotating shaft 2101 secures sleeve 2103. The piston structure 21 includes two sleeves 2103, mounting ring 2104, sliding sleeve 2107, connecting sleeve 2108, push arms 2110, and return springs 2111. There are also four swing arms 2105, four balls 2106, and four connecting rods 2109. The two mounting rings 2104, four connecting rods 2109, and two push arms 2110 are symmetrically arranged.

[0056] Among them, such as Figure 10 As shown, the two connecting sleeves 2108 are provided with a pressure structure 23, which includes two fixed seats 2301, two pressure rods 2302, and a pressure sleeve 2303. The two pressure rods 2302 are fixedly installed between the two fixed seats 2301, and the opposite ends of the two pressure rods 2302 extend into the pressure sleeve 2303. The two fixed seats 2301 are respectively bolted to the outer surfaces of the two connecting sleeves 2108. A pressure sensor is installed in the pressure sleeve 2303 to cooperate with the two pressure rods 2302. The pressure sensor is electrically connected to the drive motor 1901. When the two connecting sleeves 2108 move relative to each other, the two pressure rods 2302 move into the pressure sleeve 2303 and squeeze the pressure sensor, thereby closing the rotating shaft 2101. At this time, the piston block 2102 returns to its original state via the return spring 2111.

[0057] In order to improve the cleaning of the inner wall of the vacuum pipe, in this embodiment, Figure 8As shown, a sprinkler assembly is provided on the piston block 2102, and the sprinkler assembly includes a nozzle 2114 and a water pipe 2115. A cavity 2112 is provided inside the piston block 2102, and a mounting hole 2113 connected to the cavity 2112 is opened inside the piston block 2102. The nozzle 2114 can be detachably installed in the mounting hole 2113, and the water pipe 2115 is flange-connected to the upper surface of the piston block 2102, and the water pipe 2115 is connected to the cavity 2112. The water pipe 2115 is connected to the conveying equipment, and there are multiple nozzles 2114, and the multiple nozzles 2114 are respectively located on the side wall and the lower surface of the piston block 2102. The piston block 2102 reciprocates inside the pipe, which helps to remove residues or grease attached to the inner wall of the pipe, thereby cleaning the inner wall of the pipe. At the same time, the nozzle 2114 is used to spray an appropriate amount of water or other detergent into the pipe to further help flush the inner wall of the pipe and enhance the cleaning effect. The nozzle 2114 located on the lower surface of the piston block 2102 can also flush the crushing roller 1902 to reduce garbage residue.

[0058] In order to improve the linkage of the structure, in this embodiment, Figure 3 As shown, a transmission structure 22 is disposed between the crusher 19 and the piston structure 21. The transmission structure 22 includes two transmission wheels 2201 and a transmission belt 2202 connected between the two transmission wheels 2201. The two transmission wheels 2201 are respectively connected and fixed to one of the crushing rollers 1902 and the end of the rotating shaft 2101. The transmission structure 22 organically combines the crusher 19 and the piston structure 21 to form an efficient and stable food waste pipeline treatment device, which improves the efficiency and quality of waste treatment.

[0059] It should be noted that the depth of the connecting pipe 18 is adapted to the storage space within the inlet 1. When the food waste inside the inlet 1 accumulates to a certain level, it is discharged into the connecting pipe 18. The bottom end of the connecting pipe 18 is connected to the storage tank 2 via a connecting pipe. When the crusher 19 and the piston structure 21 are in operation, the valve group 16 is in a closed state. The number of crushing devices 17 is set according to the inlet 1, so that the food waste is crushed before entering the storage tank.

[0060] Another technical problem to be solved by the present invention is to provide a control method for collecting and transporting kitchen waste in a vacuum pipeline, comprising the following steps:

[0061] 1) Material delivery: Food waste is delivered to the pipeline through indoor delivery port 1-1 and commercial delivery port 1-2. The vacuum space formed by energy storage tank 3 and material storage tank 2 collects the food waste in delivery port 1. The food waste is then crushed by crushing equipment 17. This step can solve the problem of difficult collection and transportation in high-rise and super-high-rise buildings, and can also solve the problem of multiple households on one floor disposing of waste indoors.

[0062] 2) Material storage: After the liquid level sensor in the material storage tank 2 detects that the material has reached the set position, the vacuum pump 5 creates a vacuum space between the energy storage tank 2 6 and the material storage tank 2 4 to collect the kitchen waste in the material storage tank 2 and store it in the material storage tank 2 4;

[0063] 3) Discharge: After the liquid level sensor in the storage tank 2 4 detects that the liquid level has reached the set value, the discharge group 8 transports the kitchen waste in the storage tank 2 4 to the discharge interface or connects it to the next process;

[0064] 4) Treatment: The kitchen waste enters the dehydrator 12 for dehydration. The dehydrated residue enters the degradation machine 11 for biodegradation. The dehydrated wastewater passes through the sewage extraction device 13 and enters the oil-water separator 14. At the same time, the residue enters the degradation machine 11 and is degraded into organic fertilizer. The oil-water separator 14 separates the oil and water. The waste oil can be recycled, and the wastewater is connected to the municipal sewage treatment system.

[0065] In addition, the vacuum pump 5 replenishes the vacuum degree of the energy storage tank 1 3 and the energy storage tank 2 6 and the pipeline to ensure the suction capacity of the system. The gas discharged by the vacuum pump 5 is treated by the exhaust gas treatment device 7 and then discharged in compliance with the emission standards. The discharge interface 15 can be connected to the garbage collection truck to transport the treated garbage. The vertical pipe at the valve group 16 is provided with a secondary cleaning device for the garbage residue in the main pipeline to ensure the pipeline is cleaned and transported thoroughly.

[0066] In summary, the processing module is controlled by the central control room 10 to collect and process the kitchen waste in the storage module. The system can cover a large area without the need for multiple dispersed systems for collection. It is energy-saving and environmentally friendly, and provides a solution for on-site treatment of kitchen waste and a solution for closed docking with the existing transfer system. At the same time, kitchen waste can be converted into organic fertilizer on-site to achieve resource recycling. The exhaust gas generated during operation is discharged after passing through a special treatment device and meets the discharge standards without polluting the environment. In addition, the kitchen wastewater is separated from the oil and water to recover the grease, and the wastewater is connected to a special wastewater treatment system for treatment and then discharged after meeting the standards, thereby maximizing resource utilization while protecting environmental hygiene.

[0067] like Figures 1-10 As shown, the principles of the vacuum pipeline kitchen waste collection and treatment system and its control method provided in this embodiment are as follows:

[0068] When the present invention is in use, kitchen waste is put into the pipeline through the indoor delivery port 1-1 and the commercial delivery port 1-2. During storage, the kitchen waste will be crushed by the crushing equipment 17. The kitchen waste entering the connecting pipeline 18 is crushed by the transmission cooperation of the driving motor 1901 and the two sets of crushing rollers 1902. When the crushing rollers 1902 rotate, the transmission cooperation of the transmission wheel 2201 and the transmission belt 2202 drives the rotating shaft 2101 to start the piston structure 21. When the rotating shaft 2101 rotates, the swing arm 2105 drives the ball 2106 to rotate. When the ball 2106 rotates, it will produce centrifugal outward expansion, thereby driving the sliding sleeve 2107 to move inward. When the sliding sleeve 2107 moves, it squeezes the push arm 2110, causing the piston block 2102 to move downward. When the piston block 2102 moves downward under the action of squeezing, it will exert additional pressure on the garbage. This pressure helps the crusher 19 to be more effective. The garbage is effectively crushed. At the same time, during the movement of the piston block 2102, its edge will rub against the inner wall of the pipe, which helps to remove residues or grease attached to the inner wall of the pipe, thereby cleaning the inner wall of the pipe. The crushed garbage enters the storage tank 2, and the vacuum space formed by the vacuum pump 5, the energy storage tank 3 and the storage tank 2 4 collects the kitchen waste in the storage tank 2 and stores it in the storage tank 2 4. When the garbage is higher than the liquid level and reaches the set value, the discharge group 8 transports the kitchen waste in the storage tank 2 4 to the discharge. First, the kitchen waste enters the dehydrator 12 for dehydration, and the dehydrated residue enters the degradation machine 11 for biodegradation. The dehydrated wastewater enters the oil-water separation device 14 through the sewage lifting device 13, and the kitchen waste in the degradation machine 11 is degraded into organic fertilizer. The oil-water separation device 14 separates the oil and water, so that the waste oil can be recycled. Finally, the sewage is connected to the municipal sewage treatment system.

[0069] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0070] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0071] The foregoing description shows and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the inventive concept described herein by the teachings above or by techniques or knowledge in the relevant art. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be within the scope of the appended claims.
