Description

Technical Field

[0001] This invention belongs to the technical field of environmental protection equipment, and in particular relates to a mobile, vehicle-mounted oil-water separator suitable for kitchen waste. Background Technology

[0002] With economic development and the continuous expansion of cities, the amount of urban household waste is constantly increasing. The rise of the catering industry, while providing convenience, also poses a significant challenge to the environment. Food waste can be divided into two main categories: kitchen waste and waste cooking oil. Waste cooking oil refers to inedible animal and vegetable oils and various water-oil mixtures, including oils that have been used for frying food and are no longer edible, commonly known as "old oil." The oil and water-oil mixture in food waste is commonly known as "swill oil." Oil produced after separation and treatment using oil-water separators and grease traps is commonly known as "gutter oil."

[0003] In practical operation, the main process involves using oil-water separation equipment to separate solid and liquid waste from kitchen waste. The liquid waste is a mixture of oil and water. This mixture is then separated to collect waste oil for industrial use. Most existing oil-water separation equipment uses solid-liquid separation as its first step. The most common method is using a filter basket, but this requires emptying the basket of solid waste later. Alternatively, a method can be used, such as the oil-water separation vehicle-mounted device disclosed in patent application number 201920673259.0, which includes: an oil-water separation chamber with a swill inlet and a first filter plate with first perforations at its bottom to retain at least a portion of the solid residue in the swill entering the oil-water separation chamber; a second chamber located below the oil-water separation chamber to receive kitchen waste—swill—leaking from the first filter plate; and a third chamber adjacent to the second chamber in the horizontal direction. The system is further divided by a second filter plate with second perforations. The second filter plate is positioned such that all the first perforations are located above the second chamber. This structure allows for more thorough solid-liquid separation of the swill, ensuring that at least a portion of the solid residue entering the second chamber is retained there, reducing the possibility of solid residue entering the third chamber. However, this structure uses fixed filter plates for both solid and liquid separation, which presents the following problems: 1. During the filtration of solid waste, prolonged use can easily clog the filter pores with debris or oil (which is present in the swill), affecting the subsequent filtration effect and making cleaning the filter plates inconvenient; 2. Because the filter plates are fixed, the flowability of solid waste is poor, and excessive swill can easily affect filtration efficiency; 3. Furthermore, the effluent water quality fails to meet discharge standards. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile, vehicle-mounted oil-water separation device suitable for kitchen waste, which solves the problems of existing oil-water separation devices where the filter plates for solid-liquid separation are easily clogged by garbage or oil after long-term use, thus affecting the subsequent filtration effect; and the current filter plates are fixed, so when filtering solid waste, the flowability of the waste is poor, and once too much swill enters, the filtration efficiency is easily affected.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a mobile, vehicle-mounted oil-water separation device suitable for kitchen waste, comprising a housing and a control cabinet for controlling the electrical equipment. The housing is divided into three sections: oil-water separation tank 1, oil-water separation tank 2, oil-water separation tank 3, a slow flocculation tank, an activated carbon filter chamber, a sand filter chamber, a fast flocculation tank, and a chemical dosing tank. An oil storage tank is detachably connected to the housing. Oil-water separation tanks 1, 2, fast flocculation tank, slow flocculation tank, activated carbon filter chamber, and sand filter chamber are sequentially connected for filtering the transported water. The chemical dosing tank is connected to the fast flocculation tank and is used to add chemicals to the fast flocculation tank. Oil-water separation tank 1 has baffles that divide its upper part into left and right sides. A mesh conveyor belt is located on the upper left side of the first oil-water separator.

The wastewater generated after backwashing the activated carbon filter chamber flows into the backwash wastewater tank, which is equipped with a wastewater supply pump. The output of the wastewater supply pump... The end is connected to the input port of the screw press in the dewatering tank. The spray heating drive mechanism includes a high-pressure spray gun, an electromagnetic heating coil, and a temperature sensor. The input end of the high-pressure spray gun is connected to the output end of the backwash pump. The output end of the high-pressure spray gun is connected to a spray delivery pipe that communicates with the spray pipes on each spray group. The spray delivery pipe is surrounded by one or more electromagnetic heating coils. The temperature sensor is installed inside the spray delivery pipe. The temperature sensor, electromagnetic heating coil, and high-pressure spray gun are electrically connected to the control cabinet.

[0008] Preferably, to improve oil-water separation efficiency, the first oil-water separation tank is equipped with an oil scraping device, the second oil-water separation tank is equipped with a filter, and one side of the oil scraping device is equipped with an oil guide groove for conveying the oil from the first oil scraping device to the oil storage tank. The activated carbon filter chamber is equipped with an activated carbon filter. The first oil scraping device is located on the right side of the first oil-water separation tank. An overflow port is provided on the partition between the first and second oil-water separation tanks. The partition between the second and third oil-water separation tanks is... An overflow port 2 is provided. A water pump 1 is installed inside the oil-water separation tank 3 to pump water from the oil-water separation tank 3 into the rapid flocculation tank. An overflow port 3 is provided on the side of the rapid flocculation tank, which is connected to the slow flocculation tank. The overflow port 3 is used to overflow water from the rapid flocculation tank into the slow flocculation tank. An activated carbon water pump is installed inside the slow flocculation tank to pump water from the slow flocculation tank into the activated carbon filter chamber. A dosing tank is provided inside the dosing tank, which is connected to the rapid flocculation tank. The dosing pump is used to inject chemicals into the rapid flocculation tank.

[0009] Preferably, for ease of operation, the output end of the backwash pump is connected to a T-junction pipe. The first port of the T-junction pipe is connected to the output end of the backwash pump, the second port of the T-junction pipe is connected to the activated carbon filter chamber, and the third port of the T-junction pipe is connected to the spray delivery pipe. A water pumping pipe is also connected to the pipeline connecting the T-junction pipe and the activated carbon filter chamber. The other end of the water pumping pipe is connected to the dosing tank. A sludge pump is installed in the first oil-water separation tank, and a sludge pump is installed in the second oil-water separation tank. The output ports of both the first and second sludge pumps are connected to a drain pipe, and the other end of the drain pipe is connected to the rapid flocculation tank.

[0010] As a preferred option, to further improve the oil-water separation efficiency, an oil scraping device 2 is also provided in the oil-water separation tank 2, and an oil scraping device 3 is also provided in the oil-water separation tank 3. An L-shaped oil guide trough is provided above the oil-water separation tank 2 and the oil-water separation tank 3 to transport the oil conveyed by the oil scraping device 2 and the oil scraping device 3 to the oil storage tank.

[0011] Preferably, in order to further prevent solid debris from remaining on the mesh conveyor belt and ultimately affecting the solid-liquid separation effect, the oil-water separation tank on the left side of the baffle is equipped with a scraper near the drive shaft for scraping off debris from the mesh conveyor belt.

[0012] Preferably, to improve the filtration effect on water and facilitate subsequent filter cleaning and reduce costs, the filter includes one or more filter plates stacked sequentially from top to bottom. Each filter plate includes a plastic substrate with one or more lugs distributed in a ring on the plastic substrate. Each lug has a protruding post with a through hole on its front side and a limiting post on its back side that is inserted into and limited by the protruding post on the adjacent plastic substrate. The limiting post has a second through hole aligned with the first through hole. After all the filter plates are inserted sequentially, they are locked together using long screws and nuts. Each plastic substrate has one or more filter through hole grooves in a ring on its front side and corrugated guide strips extending along the outer wall of each filter through hole groove on its back side.

[0013] Preferably, to facilitate subsequent slag discharge, a slag discharge port is provided on one end of the box body near the mesh conveyor belt. The slag discharge port is used to discharge the garbage conveyed above the mesh conveyor belt from the oil-water separator. A garbage bin is provided on the side of the box body below the slag discharge port. The garbage bin is detachably connected to the box body. The sludge outlet on the screw press is also connected to the garbage bin to send the sludge produced by the screw press into the garbage bin. A clean water outlet is provided at the bottom of the sand filter box.

[0014] As a preferred design, to make the overall structure more compact, a sludge suction pump is connected to the side inlet, which is located to the left of the oil storage tank. Oil-water separation tanks two and three are located to the right of oil-water separation tank one. Oil-water separation tank two is located between oil-water separation tank three and the dehydration tank. A backwash wastewater tank is located to the right of oil-water separation tank two. An activated carbon filter chamber and a control cabinet are located to the right of oil-water separation tank three. The activated carbon filter chamber is located between the control cabinet and the backwash wastewater tank. An L-shaped sand filter is located to the right of the activated carbon filter chamber and the control cabinet. The rapid flocculation tank, the chemical dosing tank, and the slow flocculation tank are arranged adjacently and located to the right of the backwash wastewater tank. The oil storage tank is located behind oil-water separation tank three.

[0015] The present invention also discloses a method for using the aforementioned mobile vehicle-mounted oil-water separator suitable for kitchen waste on a mobile vehicle-mounted device.

[0016] The present invention has the following beneficial effects:

[0017] 1. This structure uses a spray heating drive mechanism to spray and wash the mesh of the conveyor belt under high pressure, which prevents garbage from clogging the mesh of the conveyor belt and affecting the solid-liquid separation effect in the later stage. Moreover, the mesh conveyor belt will not clog the mesh after long-term use.

[0018] 2. Furthermore, this structure employs a conveyor belt system for solid-liquid filtration, transporting kitchen waste (i.e., swill) from the side inlet. This ensures greater fluidity of the waste, allowing for continuous wastewater treatment without affecting filtration efficiency due to excessive swill entering the system.

[0019] 3. At the same time, high-pressure and high-temperature rinsing is used to further rinse the debris in the mesh and also to rinse the residual oil in the mesh with high temperature, so as to prevent the oil from clogging the mesh after cooling and affecting the filtration effect.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1-10As shown in this embodiment, a mobile vehicle-mounted oil-water separator suitable for kitchen waste includes a housing 1 and a control cabinet 35 for controlling the electrical equipment. The housing 1 has an internal partition dividing it into three sections: an oil-water separator 101, an oil-water separator 102, an oil-water separator 103, a slow flocculation tank 104, an activated carbon filter chamber 105, a sand filter chamber 106, a fast flocculation tank 108, and a chemical dosing tank 109. An oil storage tank 110 is detachably connected to the housing 1. This detachable connection is achieved by placing a [missing information - likely a device or structure] on the housing 1 near the control cabinet 35 and the oil-water separator 103. The platform has an oil storage tank 110 whose bottom can be fastened to the platform with snap-fit ​​mechanisms. The top of the oil storage tank 110 has a large opening to facilitate the flow of oil from the L-shaped oil guide channel 31 and the first oil guide channel 7 into the oil storage tank 110. The oil-water separator 101, oil-water separator 102, rapid flocculation tank 108, slow flocculation tank 104, activated carbon filter chamber 105, and sand filter chamber 106 are sequentially connected for filtering the transported water. The dosing tank 109 is connected to the rapid flocculation tank 108 and is used to add chemicals to the rapid flocculation tank 108. The oil-water separator 101 has a structure that isolates the upper part of the oil-water separator 101 into a left... On the right side baffles 9, a mesh conveyor belt 10 is provided on the upper left side inside the oil-water separator 101. A side inlet 11 is located above the mesh conveyor belt 10 and communicates with the oil-water separator 101. One end of the mesh conveyor belt 10 is fitted onto a synchronous shaft 12, and the other end is fitted onto a drive shaft 13. In this embodiment, the transmission power of the drive shaft 13 comes from a drive motor 131 located outside the oil-water separator 101. The output shaft of the drive motor 131 passes through the oil-water separator 101 and connects to the drive shaft 13. When the drive motor 131 is working... The working time needs to be consistent with that of each oil scraping device; the synchronous shaft 12 and the transmission shaft 13 are rotatably connected in the oil-water separator 101. One or more spray groups 14 are distributed circumferentially on the transmission shaft 13. Each spray group 14 includes a spray pipe 141 and one or more spray holes 15 provided on the spray pipe 141. A heating box 112 is provided on the side of the oil-water separator 101. The heating box 112 is provided with a spray heating drive mechanism that is connected to the spray group 14 and the sand filter box 106 respectively. The spray heating drive mechanism is used to draw water from the sand filter box 106, heat it and spray it out from the spray group 14.

[0035] The above-described structure enables high-pressure spray washing of the mesh conveyor belt 10 by a spray heating drive mechanism, preventing garbage from clogging the mesh of the conveyor belt 10 and affecting the subsequent solid-liquid separation effect. Moreover, the mesh conveyor belt 10 will not clog the mesh even after long-term use. Furthermore, the garbage above the mesh conveyor belt 10 can be discharged through the slag discharge port 39 set at the front end of the oil-water separation tank 101. The specific structure of the slag discharge port 39 is conventional technology in this field and will not be described in detail. In addition, this structure uses a conveyor-type mesh conveyor belt 10 to transport kitchen waste (i.e., swill) transported from the side water inlet 11 for solid-liquid filtration, ensuring that the garbage has strong fluidity and that the filtration efficiency will not be affected by too much swill entering.

[0036] Preferably, to ensure more stable output and improve heating safety, the housing 1 is also equipped with a dehydration tank 107 and a backwash wastewater tank 111 for wastewater buffering. The backwash wastewater tank 111 is located on the side of the sand filter 106 and the activated carbon filter chamber 105. The dehydration tank 107 is equipped with a screw press 17. The sand filter 106 is equipped with a backwash pump 22. The output end of the backwash pump 22 is connected to the activated carbon filter chamber 105 to rinse the activated carbon filter 8 inside the activated carbon filter chamber 105. The wastewater generated after backwashing the activated carbon filter chamber 105 flows into the backwash wastewater tank 111. The backwash wastewater tank 111 is equipped with a wastewater supply pump 32. The output end of the wastewater supply pump 32 is connected to the input port of the screw press 17 in the dehydration tank 107.

[0037] like Figure 10 As shown, the spray heating drive mechanism includes a high-pressure spray gun 161, an electromagnetic heating coil 163, and a temperature sensor 164. The input end of the high-pressure spray gun 161 is connected to the output end of the backwash pump 22. The output end of the high-pressure spray gun 161 is connected to a spray delivery pipe 162 that communicates with the spray pipes 141 on each spray group 14. The spray delivery pipe 162 is surrounded by one or more electromagnetic heating coils 163. The temperature sensor 164 is installed inside the spray delivery pipe 162. The temperature sensor 164, the electromagnetic heating coil 163, and the high-pressure spray gun 161 are electrically connected to the control cabinet 35. The water generated by the screw press 17 returns to the sand filter box 106 through the external pump 171 generated by the screw press.

[0038] In this embodiment, the working principle of the spray heating drive mechanism is as follows: First, the high-pressure spray gun 161 and the electromagnetic heating coil 163 are electrically connected to the control cabinet 35. The control cabinet 35 controls the operation or stop of the high-pressure spray gun 161 and controls the heating or stopping operation of the electromagnetic heating coil 163. When the high-pressure spray gun 161 needs to work, the control cabinet 35 controls the high-pressure spray gun 161 to open. At this time, the high-pressure spray gun 161 delivers part of the water delivered by the backwash pump 22 to the spray delivery pipe 162, and then the spray delivery pipe 162 delivers the water to each spray pipe 1. 41. High-pressure spraying is achieved using multiple spray holes 15 of the spray pipe 141 to clean the area above the mesh conveyor belt 10, preventing debris from remaining in the mesh of the conveyor belt 10. Clogged mesh ultimately affects the solid-liquid filtration effect. Since the side inlet 11 receives not only solid-liquid mixtures but also oil, an electromagnetic heating coil 163 heats the water transported by the spray conveyor pipe 162, and a temperature sensor 164 monitors the water temperature in real time. Once the water temperature reaches the preset temperature, the electromagnetic... Heating coil 163 stops heating, and during the spraying process, high temperature is used to wash away the oil remaining on the mesh conveyor belt 10, preventing oil residue from remaining on the mesh conveyor belt 10 and affecting the solid-liquid separation effect. It should be noted that for ease of installation and later maintenance, the spray conveying pipe 162 is installed inside the heating box 112. The hinged cover on top of the heating box 112 is not shown in the diagram. When maintenance is needed, the cover on top of the heating box 112 can be opened for easy maintenance or replacement of the electromagnetic heating coil 163. The electrical connection between the electromagnetic heating coil 163 and the high-pressure spray gun 161 and the control cabinet 35, and how they are controlled by the control cabinet 35, as well as the connection between the spray pipe 141 and the spray delivery pipe 162, are all conventional technologies in the field and will not be described in detail. It should also be noted that in order to ensure that the rotation of the drive shaft 13 does not affect the spray pipe 141, the connection between the spray pipe 141 and the spray delivery pipe 162 is made by hinge. As long as the sealing is ensured later, this is conventional technology for those skilled in the art and will not be described in detail.

[0039] Preferably, to improve oil-water separation efficiency, the oil-water separation tank 101 is equipped with an oil scraping device 2. In this embodiment, the oil scraper on the oil scraping device 2 needs to protrude outward by 30mm. In this embodiment, the oil scraping device 2 is located on the upper right side inside the oil-water separation tank 101. Later, a common oil scraper can be used to scrape the floating oil on the right side surface of the oil-water separation tank 101 to the oil guide groove 7, and then let it flow into the oil storage tank 110 by gravity. The oil-water separation tank 102 is equipped with a filter 3. The side of the oil scraping device 2 is equipped with an oil guide groove 7 for conveying the oil transported by the oil scraping device 2 to the oil storage tank 110. The activated carbon filter chamber 105 is equipped with an activated carbon filter 8. In this embodiment, to improve the filtration effect, the activated carbon filter 8 can be replaced by a bag filter. The oil scraping device 2 is located on the right side inside the oil-water separation tank 101. An overflow port 18 is provided on the partition between oil-water separator 101 and oil-water separator 102. An overflow port 29 is provided on the partition between oil-water separator 102 and oil-water separator 103. A water pump 20 is provided inside oil-water separator 103 to pump water into rapid flocculation tank 108. An overflow port 34 is provided on the side of rapid flocculation tank 108, which communicates with slow flocculation tank 104. Overflow port 3 4 is used to overflow water in the rapid flocculation tank 108 into the slow flocculation tank 104, where flocculation and sedimentation continue. At the same time, the slow flocculation tank 104 is equipped with an activated carbon water pump 5 for pumping water from the slow flocculation tank 104 into the activated carbon filter chamber 105. The dosing tank 109 is equipped with a dosing pump 6 for communicating with the rapid flocculation tank 108, and the dosing pump 6 is used to pump chemicals into the rapid flocculation tank 108.

[0040] Preferably, for ease of operation, the output end of the backwash pump 22 is connected to a T-junction pipe 21. The first port of the T-junction pipe 21 is connected to the output end of the backwash pump 22, the second port of the T-junction pipe 21 is connected to the activated carbon filter chamber 105, and the third port of the T-junction pipe 21 is connected to the spray delivery pipe 162. A water pumping pipe 37 is also connected to the pipe connecting the T-junction pipe 21 and the activated carbon filter chamber 105. The other end of the water pumping pipe 37 is connected to the dosing tank 109. A sludge pump 25 is installed in the first oil-water separator 101, and a sludge pump 27 is installed in the second oil-water separator 102. The output ports of both the first sludge pump 25 and the second sludge pump 27 are connected to a drain pipe 23. The other end of the drain pipe 23 is connected to the rapid flocculation... The condensation tank 108 is connected; in this embodiment, in order to realize the backwashing operation, water is pumped into the activated carbon filter chamber 105 by the backwashing pump 22 to perform the backwashing operation on the activated carbon filter chamber 105. The wastewater generated in the activated carbon filter chamber 105 is sent into the backwash wastewater tank 111. It should be noted that the sand filter chamber 106 is filled with filter sand to filter the water, and then the water is discharged through the drain outlet 34. In this embodiment, the specific heights of overflow outlet 18 and overflow outlet 29 need to be set according to the actual situation. It is only necessary to ensure that the overflow outlet 18 can allow the water in the oil-water separator 101 to flow into the oil-water separator 202, and the overflow outlet 219 can allow the filtered water in the oil-water separator 202 to flow into the oil-water separator 303. It should be noted that the specific structure of the screw press 17 (which includes the screw press body and the screw press water tank) and the backwash pump 22, as well as how the screw press 17, the backwash pump 22, and the slag pump 25 are electrically connected to the control cabinet 35, are conventional technologies in the field and therefore will not be described in detail.

[0041] In this embodiment, a drug inlet and a sealing cap are provided above the dosing tank 109. This is prior art to those skilled in the art and will not be described in detail. To ensure that the drug in the dosing tank 109 is mixed with water before being sent to the corresponding rapid flocculation tank 108, a water pumping pipe 37 is connected at one end to a three-way pipe 21, and at the other end to the dosing tank 109 via an electric valve. After the electric valve is opened, under the high pressure of the backwash pump 22, some water from the backwash pump 22 flows into the dosing tank 109 through the water pumping pipe 37. The water and drug are then mixed by the internal stirring mechanism 24 of the dosing tank 109 before being pumped into the rapid flocculation tank 108 by the dosing pump 6, ultimately ensuring that the drug is mixed... After being mixed evenly, the mixture is sent into the flocculation box to ensure that the wastewater is treated more evenly by the drugs in the later stage. In this embodiment, both the slow flocculation box 104 and the fast flocculation box 108 are equipped with a stirring mechanism 20. It should be noted that the stirring mechanism 20 and the stirring mechanism 14 have the same structure, both including a stirring motor and stirring blades. Since the fast flocculation box 108 is a fast stirring box and the slow flocculation box 104 is a slow stirring box, the stirring speed in the fast flocculation box 108 is faster than the stirring speed in the slow flocculation box 104. The specific structure of the stirring mechanism 20 and the stirring mechanism 14 is conventional technology in the field, so it will not be described in detail. Moreover, the stirring mechanism 14 uses long-term continuous stirring with a stirring speed of 90 revolutions per minute.

[0042] Preferably, to further improve the oil-water separation efficiency, an oil scraping device 29 is also provided in the second oil-water separation tank 102, and an oil scraping device 30 is also provided in the third oil-water separation tank 103. An L-shaped oil guide groove 31 is provided above the second oil-water separation tank 102 and the third oil-water separation tank 103 to transport the oil conveyed by the oil scraping device 29 and the oil scraping device 30 to the oil storage tank 110. In this embodiment, the structures of the oil scraping device 29, the oil scraping device 2, and the oil scraping device 30 are the same. In this embodiment, each oil scraping device is an existing oil scraping device, which includes an acrylic roller and a drive motor for driving the acrylic roller to rotate. Considering that the oil scraping device is existing technology, it will not be described in detail.

[0043] Preferably, to further prevent solid debris from remaining on the mesh conveyor belt and ultimately affecting the solid-liquid separation effect, a scraper 28 is provided in the oil-water separation tank 101 on the left side of the baffle 9, near the drive shaft 13, to scrape debris off the mesh conveyor belt 10. In this embodiment, the scraper 28 is installed by mounting two L-shaped brackets 36 on both sides of the scraper 28. The upper end of the left L-shaped bracket 36 is fixed to the left side wall of the oil-water separation tank 101 with screws, and the upper end of the right L-shaped bracket 36 is fixed to the baffle 9 with screws, thus achieving the installation of the scraper 28. Furthermore, the scraper 28 is made of silicone material, which does not damage the mesh conveyor belt 10 when scraping material. In order to improve work efficiency in the future, the scraper 28 can be set to an automated mode, with a drive mechanism driving the scraper 28 to swing back and forth to transport the solid waste above the mesh conveyor belt 10 from the mesh conveyor belt 10 to the slag discharge port 39 set at the front end of the oil-water separator 101. It is only necessary to ensure that the height of the slag discharge port set at the front end of the oil-water separator 101 is consistent with the height of the scraper 28. This is a conventional technology for those skilled in the art, so it will not be described in detail.

[0044] As a preferred option, such as Figure 6-9 As shown, to improve the water filtration effect and facilitate subsequent filter cleaning, thereby reducing costs, the filter 3 includes one or more filter plates stacked sequentially from top to bottom. Each filter plate includes a plastic substrate 301. The plastic substrate 301 has one or more lugs 302 arranged in a ring on its surface. Each lug 302 has a protruding post 304 with a through hole 303 on its front side. On the back side of each lug 302, a limiting post 305 is provided for insertion and positioning with the protruding post 304 on the adjacent plastic substrate 301. The limiting post 305 has a second through hole 3 aligned with the first through hole 303. 08. After all the filter elements are inserted in sequence, the long screw 309 is used to pass through the aligned through holes 1 303 and through holes 2 308 from bottom to top, and then passes out from the uppermost through hole 1 303 and locks with the nut 310. Each plastic substrate 301 has one or more filter through hole grooves 306 on the front side. On the back side of the plastic substrate 301, there are corrugated guide strips 307 that extend along the outer wall of each filter through hole groove 306. At the same time, in order to further improve the filtration effect, a filter 2 with the same structure as filter 1 3 can be installed in the oil-water separator 3 103.

[0045] Preferably, to facilitate subsequent slag discharge, a slag discharge port 39 is provided on one end of the housing 1 near the mesh conveyor belt 10. The slag discharge port 39 is used to discharge the garbage conveyed above the mesh conveyor belt 10 from the oil-water separator 101. A garbage bin 38 is provided on the side of the housing 1 below the slag discharge port 39. The garbage bin 38 is detachably connected to the housing 1. The sludge port 172 on the screw press 17 is also connected to the garbage bin 38 and is used to send the sludge produced by the screw press 17 into the garbage bin 38. A clean water outlet 34 is provided at the bottom of the sand filter box 106.

[0046] Preferably, to make the overall structure more compact, a suction pump 26 is connected to the side inlet 11. The suction pump 26 is located to the left of the oil storage tank 110. The second oil-water separator 102 and the third oil-water separator 103 are located to the right of the first oil-water separator 101. The second oil-water separator 102 is located between the third oil-water separator 103 and the dehydration tank 107. A backwash wastewater tank 111 is located to the right of the second oil-water separator 102. An activated carbon filter chamber 105 and a control cabinet 35 are located to the right of the third oil-water separator 103. The activated carbon filter chamber 105 is located between the control cabinet 35 and the backwash wastewater tank 111. An L-shaped sand filter box 106 is provided on the right side of the activated carbon filter chamber 105 and the control cabinet 35. The rapid flocculation box 108, the dosing box 109, and the slow flocculation box 104 are arranged adjacently and located on the right side of the backwash wastewater tank 111. The oil storage tank 110 is located behind the oil-water separator 103. In this embodiment, a suction pump 26 is provided to automatically suck kitchen waste into the side inlet 11 to achieve automatic feeding, further improving work efficiency.

[0047] This embodiment also discloses a method of applying the mobile vehicle-mounted oil-water separator suitable for kitchen waste to a mobile vehicle-mounted device. Later, it is only necessary to set two channel steels 33 at the bottom of the entire container 1, and then use the channel steels 33 in conjunction with screws to fix the container 1 to the mobile vehicle-mounted device, thus finally realizing a mobile oil-water separator.

[0048] like Figure 3As shown, the specific working principle of this invention is as follows: For kitchen waste—i.e., swill—generated by a restaurant, it is directly sucked in by a suction pump 26. The mesh conveyor belt 10 inside the oil-water separator 101 is activated to perform solid-liquid separation of the swill. Solid waste remains above the mesh conveyor belt 10 and is then scraped to the discharge port 39 by a scraper 28, and discharged into the garbage bin 38. The oil-water mixture enters the bottom of the oil-water separator 101, with the oil floating on top. The oil is scraped into the oil guide trough 7 by the oil scraping device 2, and flows from the oil guide trough 7 into the oil storage tank 110. Simultaneously, the filtered liquid overflows through the overflow port 18 into the oil-water separator 202. If oil remains in the oil-water separator 202 at this time, the oil floats on the surface of the oil-water mixture. Above the second oil-water separator 102, the oil is scraped off by the second oil scraping device 29 inside the second oil-water separator 102, and flows into the oil storage tank 110 through the L-shaped oil guide channel 31. The liquid in the second oil-water separator 102 is filtered to remove impurities by the first filter 3, and then the filtered liquid overflows into the third oil-water separator 103 through the overflow port 219 for buffering. If there is residual oil in the third oil-water separator 103 at this time, the oil floats above the third oil-water separator 103 and is scraped off by the third oil scraping device 30 inside the third oil-water separator 103, and flows into the oil storage tank 110 through the L-shaped oil guide channel 31. The oil is scraped off three times through the first oil-water separator 101, the second oil-water separator 102, and the third oil-water separator 103 to further improve the oil-water separation effect.

[0049] Then, water is pumped into the rapid flocculation tank 108 by the water pump 20 in the oil-water separator 103. Chemical solution is added from the dosing tank 109 by the dosing pump 6, achieving rapid flocculation and sedimentation of the wastewater. Simultaneously, the water is stirred and mixed evenly. After rapid flocculation, the water overflows through the overflow port 4 into the slow flocculation tank 104 for further flocculation and sedimentation, achieving a slow flocculation effect on the wastewater. This structure further improves the flocculation effect on wastewater by setting up rapid and slow flocculation. The water after slow flocculation is pumped into the activated carbon filter chamber 105 by the activated carbon pump 5. The activated carbon in the activated carbon filter chamber 105 filters the water, removing organic matter, heavy metals, odors, and other pollutants, as well as COD, ensuring the output meets requirements. The clean water treated by the activated carbon filter chamber 105 is directly transported to the sand filter chamber 106 for sand filtration and then discharged directly from the clean water outlet 34. Furthermore, because the sand filter chamber 106 contains… A backwash pump 22 is installed. When the activated carbon filter chamber 105 needs to be backwashed later, the backwash pump 22 draws clean water from the sand filter box 106 and returns it to the activated carbon filter chamber 105 for backwashing. The wastewater generated during the backwashing of the activated carbon filter chamber 105 flows into the backwash wastewater tank 111. Since the water volume during the backwashing of the activated carbon filter chamber 105 is relatively large, the backwash wastewater tank 111 is added as a buffer. At the same time, the water in the backwash wastewater tank 111 is pumped into the screw press 17 through the wastewater supply pump 32. The sludge generated after treatment by the screw press 17 flows into the garbage bin 38 through the sludge outlet 172. The water generated after treatment by the screw press 17 is pumped into the sand filter box 106 through the external supply pump 171 of the screw press. After sand filtration in the sand filter box 106, the clean water is discharged directly from the clean water outlet 34, thus completing the entire water treatment process and realizing the treatment of kitchen waste.

[0050] It should be noted that the clean water pumped by the backwash pump 22 from the sand filter box 106 has three functions: one part returns to the activated carbon filter chamber 105 for backwashing, another part flows into the dosing tank 109 through the water pumping pipe 37 as makeup water for the dosing tank 109, and the other part is delivered to the spray delivery pipe 162 through the high-pressure spray gun 161, and then supplied to each spray hole 15 through the spray pipe 141. In order to adjust the spray size of the spray delivery pipe 162 in the future, an adjustable spray valve can be installed on the spray delivery pipe 162 for control.

[0051] Meanwhile, when the water is not filtered later, the sludge at the bottom of the oil-water separator 101 can be extracted by the sludge pump 25 and sent to the rapid flocculation box 108 through the sewage pipe 23 to achieve sludge flocculation. The sludge at the bottom of the oil-water separator 102 can be extracted by the sludge pump 27 and sent to the rapid flocculation box 108 through the sewage pipe 23 to achieve sludge flocculation.

[0052] It should also be noted that, to prevent the slow flocculation tank 104 from becoming too full, an overflow port can be installed on the side of the slow flocculation tank 104 to allow water to overflow into the screw press 17. Additionally, cleaning ports can be installed at the bottom of the oil-water separator 101, oil-water separator 102, oil-water separator 103, slow flocculation tank 104, activated carbon filter chamber 105, sand filter chamber 106, and fast flocculation tank 108 to facilitate future cleaning of these tanks. 103, 104, 105, 106, 107, and 108 are cleaned and drained during internal cleaning. It should be noted that, in order to achieve automatic opening or closing of each connecting pipe, control valves electrically connected to control cabinet 35 can be set on each connecting pipe to achieve automatic operation of opening or closing of each pipe. As for how to set the control valves and how control cabinet 35 controls the opening or closing of the control valves, these are conventional technologies in the field and will not be described in detail.

[0053] Therefore, the present invention achieves the following advantages:

[0054] 1. This structure uses a spray heating drive mechanism to spray and wash the mesh of the conveyor belt under high pressure, which prevents garbage from clogging the mesh of the conveyor belt and affecting the solid-liquid separation effect in the later stage. Moreover, the mesh conveyor belt will not clog the mesh after long-term use.

[0055] 2. Moreover, this structure uses a conveyor belt to transport kitchen waste (i.e., swill) from the side inlet for solid-liquid filtration, which ensures that the waste has strong fluidity and the sewage treatment can be carried out continuously. The filtration efficiency will not be affected by too much swill entering, and the entire oil-water separation process is more thorough and efficient.

[0056] 3. At the same time, high-pressure and high-temperature rinsing is used to further rinse the debris in the mesh and also to rinse the oil remaining in the mesh with high temperature, so as to prevent the oil from clogging the mesh after cooling and affecting the filtration effect.

[0057] 4. Currently, grease traps, as pretreatment facilities for kitchen wastewater from the catering industry and some residential areas, primarily function to effectively separate and intercept grease and suspended solids in wastewater, preventing them from being directly discharged into the urban drainage system and thus protecting water bodies from pollution. However, over time, a large amount of grease, food residue, and sludge gradually accumulate inside the grease trap. These contaminants not only affect the separation effect of the grease trap but may also become a breeding ground for bacteria, posing a serious threat to the surrounding environmental hygiene. Moreover, if the grease trap is not properly treated, there will be multiple pollution incidents, as well as the generation of wastewater, exhaust gas, odor, and garbage. By applying this invention to mobile vehicle-mounted equipment, compared with the existing operation of using grease traps, it can solve the problem of secondary pollution of grease traps.

[0058] 5. It can also solve the problem of excessively high labor costs, because most catering kitchens currently rely solely on manual labor to collect food waste generated by restaurants, which results in excessively high labor costs.

[0059] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
