Description

Technical Field

[0001] The present invention belongs to the related technical field of environmental protection equipment, and particularly relates to a mobile vehicle-mounted oil-water separation device suitable for kitchen waste. Background Art

[0002] With the development of the economy, the scale of cities is constantly expanding, and the quantity of municipal domestic waste is continuously increasing. Especially with the rise of the catering industry, although it provides convenience for people, the rise of the catering industry is also a major test for the environment. Kitchen waste can be divided into two categories: kitchen waste and waste edible oil waste. Waste edible 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 cooking oil". The oils and water-oil mixtures in kitchen waste, commonly known as "swill oil", after being separated and treated by oil-water separators, grease traps, etc., the resulting oil is commonly known as "gutter oil".

[0003] In the actual operation process, mainly through the oil-water separation equipment, the solid waste and liquid waste in the kitchen waste are separated. The liquid waste is the water-oil mixture, and then the water-oil mixture can be separated to realize the collection of waste oil for industrial use. The first process of most existing oil-water separation equipment is solid-liquid separation. The most common method is to use a filtering basket. However, later, the solid waste in the basket needs to be dumped. Or, take the operation method of an oil-water separation vehicle-mounted device based on solid-liquid separation disclosed in Patent Application No. 201920673259.0: It includes: an oil-water separation chamber, which is provided with a swill inlet, and its bottom is a first filter plate with first leakage holes to retain at least part of the solid residues in the swill entering the oil-water separation chamber in the oil-water separation chamber; a second chamber, which is arranged below the oil-water separation chamber to receive the kitchen waste - that is, swill - leaking from the first filter plate; and a third chamber, which is adjacent to the second chamber in the horizontal direction and is separated by a second filter plate with second leakage holes; wherein, the position of the second filter plate is set in such a way that all the first leakage holes are located above the second chamber. The second filter plate with this structure makes the solid-liquid separation of the swill more thorough, so that at least part of the solid residues in the swill entering the second chamber will be retained in the second chamber to reduce the possibility of solid residues entering the third chamber. However, this structure uses fixed filter plates for both solid-liquid separation and utilizes the filter plates to achieve solid-liquid separation, but there are the following problems: 1. When the filter plate filters solid waste, after long-term use of the filter plate, the filter holes on the filter plate are easily blocked by garbage or oil (the swill contains oil), which affects the later filtration effect, and it is not convenient to clean the filter plate; 2. Since the filter plate is fixed, when filtering solid waste, the fluidity of the garbage is poor, and once too much swill enters, it is easy to affect the filtration efficiency; 3. At the same time, the various indicators of the effluent water quality cannot meet the discharge standards; therefore, improvement is needed. Summary of the Invention

[0004] The object of the present invention is to provide a mobile vehicle-mounted oil-water separation device suitable for kitchen waste, which solves the problems that the filter holes of the filter plate for solid-liquid separation in the existing oil-water separation device are easily blocked by garbage or oil after long-term use, affecting the subsequent filtration effect; and the current filter plate is fixed, so when filtering solid garbage, the fluidity of the garbage is poor, and once too much swill enters, it is easy to affect the filtration efficiency.

Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will, in conjunction with the embodiments of the present invention, clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figures 1-10As shown in the figure, a mobile vehicle-mounted oil-water separation device applicable to kitchen waste disclosed in this embodiment includes a box body 1 and a control cabinet 35 for controlling the operation of electrical equipment. A partition is provided inside the box body 1, which divides the box body 1 into an oil-water separation tank one 101, an oil-water separation tank two 102, an oil-water separation tank three 103, a slow flocculation tank 104, an activated carbon filter chamber 105, a sand filter tank 106, a fast flocculation tank 108 and a chemical dosing tank 109. A fuel tank 110 is detachably connected to the box body 1. The detachable connection method between the fuel tank 110 and the box body 1 is to set a platform at the position of the box body 1 close to the control cabinet 35 and the oil-water separation tank three 103. The bottom of the fuel tank 110 can be buckled on the platform by means of a buckle, and the upper part of the fuel tank 110 is a large opening, which is convenient for the oil flowing in the L-shaped oil guide groove 31 and the oil guide groove one 7 to flow into the fuel tank 110. The oil-water separation tank one 101, the oil-water separation tank two 102, the fast flocculation tank 108, the slow flocculation tank 104, the activated carbon filter chamber 105 and the sand filter tank 106 are connected in sequence to filter the transported water. The chemical dosing tank 109 is respectively connected to the fast flocculation tank 108 and is used for dosing the fast flocculation tank 108. A baffle 9 is provided in the oil-water separation tank one 101 to isolate the upper half of the oil-water separation tank one 101 into left and right sides. A mesh conveyor belt 10 is provided above the left side of the oil-water separation tank one 101. A side water inlet 11 is provided on the oil-water separation tank one 101 above the mesh conveyor belt 10 and is connected to the oil-water separation tank one 101. One end of the mesh conveyor belt 10 is sleeved on the synchronous shaft 12, and the other end of the mesh conveyor belt 10 is sleeved on the transmission shaft 13. In this embodiment, the driving power of the transmission shaft 13 comes from a driving motor 131 provided outside the oil-water separation tank one 101. The output shaft of the driving motor 131 passes through the oil-water separation tank one 101 and is connected to the transmission shaft 13. When the driving motor 131 works, it needs to be consistent with the working time of each oil scraping device. The synchronous shaft 12 and the transmission shaft 13 are rotatably connected inside the oil-water separation tank one 101. One or more spray groups 14 are distributed on the transmission shaft 13 in a circumferential manner. 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 separation tank one 101. A spray heating driving mechanism respectively connected to the spray group 14 and the sand filter tank 106 is provided inside the heating box 112. The spray heating driving mechanism is used to extract the water in the sand filter tank 106, heat it and spray it out from the spray group 14.

[0035] With the above structure, high-pressure spray flushing is carried out on the meshes of the mesh conveyor track 10 conveyed by using the spray heating drive mechanism, so as to avoid the blockage of the meshes of the mesh conveyor track 10 by garbage and affect the later solid-liquid separation effect. Moreover, the meshes of the mesh conveyor track 10 will not be blocked after long-term use. In addition, the garbage above the mesh conveyor track 10 can be discharged through the slag discharge port 39 provided at the front end above the oil-water separation tank 101. The specific structure of the slag discharge port 39 belongs to the conventional technology in this field, so it will not be described in detail here. Moreover, this structure uses the conveyor-type mesh conveyor track 10 to convey the kitchen waste - namely swill conveyed from the side water inlet 11, ensuring that the fluidity of the garbage becomes stronger and will not affect the filtration efficiency when too much swill enters.

[0036] Preferably, in order to ensure more stable output and improve the safety of heating at the same time, a dehydration tank 107 and a backwash waste water tank 111 for buffering waste water are further provided in the box body 1. The backwash waste water tank 111 is located on the side of the sand filter tank 106 and the activated carbon filter bin 105. A spiral press 17 is provided inside the dehydration tank 107. A backwash pump 22 is provided in the sand filter tank 106. The output end of the backwash pump 22 is communicated with the activated carbon filter bin 105 for flushing the activated carbon filter 8 inside the activated carbon filter bin 105. The waste water generated after the backwashing of the activated carbon filter bin 105 flows into the backwash waste water tank 111. And a waste water supply pump 32 is provided in the backwash waste water tank 111. The output end of the waste water supply pump 32 is connected to the input port of the spiral press 17 in the dehydration tank 107.

[0037] As Figure 10 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 communicated with the spray pipes 141 on each spray group 14. An electromagnetic heating coil 163 is annularly arranged outside the spray delivery pipe 162. The temperature sensor 164 is arranged 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 spiral press 17 returns to the sand filter tank 106 through the external supply pump 171 generated by the spiral 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 stop heating 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 conveys a part of the water delivered by the backwash pump 22 to the spray delivery pipe 162, and then the spray delivery pipe 162 conveys it to each spray pipe 141, and sprays it out under high pressure through a plurality of spray holes 15 of the spray pipe 141, so as to realize the spray cleaning operation above the mesh conveyor track 10, avoid garbage remaining in the meshes of the mesh conveyor track 10, and block the meshes of the mesh conveyor track 10, ultimately affecting the solid-liquid filtration effect. And because there is not only the solid-liquid composition but also oil entering from the side water inlet 11, the electromagnetic heating coil 163 is used to heat the water conveyed by the spray delivery pipe 162, and the water temperature is detected in real time by the temperature sensor 164. Once the water temperature reaches the preset temperature, the control electromagnetic heating coil 163 stops heating. Moreover, during the spraying process, high temperature is used to perform high-temperature flushing on the oil remaining on the mesh conveyor track 10, avoid the oil remaining on the mesh conveyor track 10, and also affect the solid-liquid separation effect. It should be noted that for the convenience of installation and later maintenance, the spray delivery pipe 162 is arranged in the heating box 112. The cover door above the heating box 112 is hinged and not shown in the figure. When later maintenance is required, the cover door above the heating box 112 can be opened to facilitate later maintenance or replacement of the electromagnetic heating coil 163. It should be noted that how the electromagnetic heating coil 163 and the high-pressure spray gun 161 are electrically connected to the control cabinet 35, how they are controlled by the control cabinet 35, and how the spray pipe 141 is connected to the spray delivery pipe 162 all belong to the conventional technologies in this field, so no specific description is made here. At the same time, it should be noted that in order to ensure that the rotation of the transmission shaft 13 will not affect the spray pipe 141, the connection between the spray pipe 141 and the spray delivery pipe 162 adopts a hinged manner, as long as the sealing performance is ensured later. This belongs to the conventional technology for those skilled in the art, so no specific description is made here.

[0039] Preferably, in order to improve the oil-water separation efficiency, an oil scraping device 2 is provided in the first oil-water separation tank 101. In this embodiment, the oil scraper on the oil scraping device 2 needs to protrude outward by 30 mm. In this embodiment, the oil scraping device 2 is located above the right side in the first oil-water separation tank 101. In the later stage, an ordinary oil scraping plate can be used. When working, the floating oil on the right side surface of the first oil-water separation tank 101 is scraped into the first oil guiding groove 7 and then flows into the oil storage tank 110 by gravity. A first filter 3 is provided in the second oil-water separation tank 102. A first oil guiding groove 7 for transporting the oil conveyed by the oil scraping device 2 into the oil storage tank 110 is provided on the side of the oil scraping device 2.

An overflow port 4 communicating with the slow flocculation tank 104 is provided on the side of the rapid flocculation tank 108. The overflow port 4 is used for overflowing the water in the rapid flocculation tank 108 into the slow flocculation tank 104 for continuous flocculation and precipitation. At the same time, an activated carbon water pump 5 for pumping the water in the slow flocculation tank 104 into the activated carbon filtering chamber 105 is arranged in the slow flocculation tank 104. A dosing pump 6 for communicating with the rapid flocculation tank 108 is arranged in the dosing tank 109. The dosing pump 6 is used for pumping the medicine into the rapid flocculation tank 108;

[0040] Preferably, for the convenience of operation, a tee pipe 21 is connected to the output end of the backwash pump 22. The first port of the tee pipe 21 communicates with the output end of the backwash pump 22, the second port of the tee pipe 21 communicates with the activated carbon filter chamber 105, and the third port of the tee pipe 21 communicates with the spray delivery pipe 162. A water extraction pipe 37 is also communicated with the pipeline of the tee pipe 21 that communicates with the activated carbon filter chamber 105. The other end of the water extraction pipe 37 communicates with the chemical dosing tank 109. A slag extraction pump 25 is arranged in the first oil-water separation tank 101, and a slag extraction pump 27 is arranged in the second oil-water separation tank 102. The output ports of the slag extraction pump 25 and the slag extraction pump 27 are both communicated with a sewage discharge pipe 23, and the other end of the sewage discharge pipe 23 communicates with the rapid flocculation tank 108. In this embodiment, to implement the backwash operation, water is pumped into the activated carbon filter chamber 105 by the backwash pump 22 for backwashing 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 tank 106 is filled with filter sand. After the water is filtered, it is then discharged through the clear water discharge port 34. In this embodiment, the specific heights of the first overflow port 18 and the second overflow port 19 need to be set according to the actual situation, as long as it is ensured that the first overflow port 18 can allow the water in the first oil-water separation tank 101 to flow into the second oil-water separation tank 102, and the setting of the second overflow port 19 can allow the filtered water in the second oil-water separation tank 102 to flow into the third oil-water separation tank 103. It should be noted that the specific structures of the spiral press 17 (including the spiral press body and the spiral press water storage tank) and the backwash pump 22, and how the spiral press 17, the backwash pump 22, and the slag extraction pump 25 are electrically connected to the control cabinet 35 belong to the conventional technologies in the art, so they will not be described in detail here.

[0041] In this embodiment, a drug inlet and a sealing cover for closing the drug inlet are provided above the drug adding box 109, which belongs to the prior art for those skilled in the art and is not described in detail herein. At the same time, in order to ensure that the drug in the drug adding box 109 can be mixed with water first and then sent to the corresponding rapid flocculation box 108, one end of the water pumping pipe 37 is connected to the three-way pipe 21, and the other end is connected to the drug adding box 109 through an electric valve. After the electric valve is opened later, under the high pressure of the backwashing pump 22, part of the water of the backwashing pump 22 flows into the drug adding box 109 through the water pumping pipe 37, and the water and the drug are stirred by the stirring mechanism 24 inside the drug adding box 109, and then sent to the rapid flocculation box 108 through the drug adding pump 6, so as to finally ensure that the drug is mixed. After being evenly mixed, it is sent into the flocculation box to ensure that the later treatment of wastewater by drugs is more uniform. In this embodiment, the slow flocculation box 104 and the fast flocculation box 108 are both provided with a stirring mechanism 2 40, and it should be noted that: the structure of the stirring mechanism 2 40 is consistent with that of the stirring mechanism 1 24, both of which include a stirring motor and a stirring blade, and because the fast flocculation box 108 is fast stirring and the slow flocculation box 104 is slow stirring, the stirring speed in the fast flocculation box 108 is faster than the stirring speed in the slow flocculation box 104, and the specific structures of the stirring mechanism 2 40 and the stirring mechanism 1 24 belong to the conventional technology in this field, so they are not described in detail, and the stirring time of the stirring mechanism 1 24 adopts long-term continuous stirring, and the stirring speed is 90 revolutions per minute.

[0042] Preferably, in order to further improve the oil-water separation efficiency, an oil scraper device 29 is further provided in the oil-water separation box 102, and an oil scraper device 30 is further provided in the oil-water separation box 103.

[0043] Preferably, in order 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 first oil-water separation tank 101 on the left side of the baffle 9 near the transmission shaft 13 for scraping the debris on the mesh conveyor belt 10. In this embodiment, the specific installation method of the scraper 28 is to install two L-shaped brackets 36 on both sides of the scraper 28. Using the two L-shaped brackets 36, the upper end of the left L-shaped bracket 36 is fixed to the left side wall of the first oil-water separation tank 101 by screws, and the upper end of the right L-shaped bracket 36 is fixed to the baffle 9 by screws, ultimately realizing the installation of the scraper 28. And the scraper 28 is made of silicone material, which does not damage the mesh conveyor belt 10 when scraping the material on the mesh conveyor belt 10. At the same time, if it is necessary to improve the working efficiency in the later stage, the scraper 28 can be set in an automated manner, and a driving mechanism drives the scraper 28 to swing back and forth to convey the solid waste above the mesh conveyor belt 10 from the mesh conveyor belt 10 to the slag discharge port 39 provided at the front end above the first oil-water separation tank 101. It only needs to ensure that the height of the slag discharge port provided at the front end above the first oil-water separation tank 101 is the same as the height of the scraper 28. This belongs to conventional technology for those skilled in the art, so no specific description is made here.

After all the filter sheets are sequentially inserted, long screws 309 are used to sequentially pass through the aligned through holes 303 and through holes 308 from bottom to top, and then pass out from the through hole 303 at the topmost part and are locked and matched with nuts 310. More than one filter through hole groove 306 is annularly provided on the front surface of each plastic substrate 301. A corrugated diversion rib 307 extending along the outer groove wall of each filter through hole groove 306 is provided on the back surface of the plastic substrate 301. At the same time, in order to further improve the filtering effect in the later stage, a second filter with the same structure as the first filter 3 can be provided in the third oil-water separation tank 103.

[0045] Preferably, in order to facilitate slag discharge in the later stage, a slag discharge port 39 is provided at one end of the box body 1 close to the mesh conveyor track 10. The slag discharge port 39 is used to discharge the garbage conveyed from above the mesh conveyor track 10 from the first oil-water separation tank 101. A garbage bin 38 is provided on the side of the box body 1 below the slag discharge port 39. The garbage bin 38 is detachably connected to the box body 1. The sludge outlet 172 on the screw press 17 is also communicated with the garbage bin 38 to send the sludge generated by the screw press 17 into the garbage bin 38. A clear water discharge port 34 is provided at the bottom of the sand filter tank 106.

[0046] Preferably, to make the overall structural layout more compact, a sewage suction pump 26 is connected to the side water inlet 11. The sewage suction pump 26 is located on the left side of the fuel tank 110. The second oil-water separation tank 102 and the third oil-water separation tank 103 are located on the right side of the first oil-water separation tank 101. The second oil-water separation tank 102 is located between the third oil-water separation tank 103 and the dehydration tank 107. A backwashing waste water tank 111 is provided on the right side of the second oil-water separation tank 102. An activated carbon filter bin 105 and a control cabinet 35 are provided on the right side of the third oil-water separation tank 103. The activated carbon filter bin 105 is located between the control cabinet 35 and the backwashing waste water tank 111.

The rapid flocculation tank 108, the chemical dosing tank 109 and the slow flocculation tank 104 are arranged adjacent to each other and are located on the right side of the backwashing waste water tank 111. The fuel tank 110 is located behind the third oil-water separation tank 103. In this embodiment, by providing the sewage suction pump 26, it is convenient to automatically suck the kitchen waste into the side water inlet 11 to achieve automatic feeding, further improving the working efficiency.

[0047] This embodiment also discloses an application of the above-mentioned mobile vehicle-mounted oil-water separation equipment suitable for kitchen waste to a mobile vehicle-mounted device. In the later stage, only two channel steels 33 need to be provided at the bottom of the whole box body 1, and then the box body 1 is fixed on the mobile vehicle-mounted device by using the channel steels 33 and screws, finally realizing a mobile oil-water separation device.

[0048] Such as Figure 3As shown in the figure, the specific working principle of the present invention is as follows: For the kitchen waste generated in the restaurant, that is, swill, it is directly sucked in by the sewage suction pump 26. The mesh conveyor track 10 in the first oil-water separation tank 101 is started to separate the solid and liquid of the swill. The solid waste remains above the mesh conveyor track 10, and then is scraped to the slag discharge port 39 by the scraper 28 and discharged into the trash bin 38 from the slag discharge port 39. And the oil-water mixture enters the bottom of the first oil-water separation tank 101. The oil floats on the upper layer. The first oil scraping device 2 is used to scrape the oil into the first oil guiding groove 7 and flows into the oil storage tank 110 through the first oil guiding groove 7. At the same time, the filtered liquid overflows into the second oil-water separation tank 102 through the first overflow port 18. If there is still oil remaining in the second oil-water separation tank 102 when flowing in at this time, the oil floats above the second oil-water separation tank 102. The second oil scraping device 29 in the second oil-water separation tank 102 is used to scrape it off and flows into the oil storage tank 110 through the L-shaped oil guiding groove 31. And the liquid in the second oil-water separation tank 102 is filtered by the first filter 3 to remove impurities. Then the filtered liquid overflows into the third oil-water separation tank 103 through the second overflow port 19 for buffering. If there is still oil remaining in the third oil-water separation tank 103 when flowing in at this time, the oil floats above the third oil-water separation tank 103. The third oil scraping device 30 in the third oil-water separation tank 103 is used to scrape it off and flows into the oil storage tank 110 through the L-shaped oil guiding groove 31. Through the above three times of oil scraping by the first oil-water separation tank 101, the second oil-water separation tank 102 and the third oil-water separation tank 103, the oil-water separation effect is further improved;

[0049] Then, the water is sent into the rapid flocculation tank 108 by the water pump 20 in the oil-water separation tank III 103. After adding the liquid medicine in the medicine adding tank 109 through the medicine adding pump 6, rapid flocculation and precipitation of the sewage are achieved. At the same time, the stirring is started and evenly stirred. After rapid flocculation, it overflows to the slow flocculation tank 104 through the overflow port III 4 for continuous flocculation and precipitation to achieve the slow flocculation effect of the sewage. This structure further improves the flocculation effect on the sewage by setting rapid flocculation and slow flocculation. The water after slow flocculation is pumped into the activated carbon filter bin 105 by the activated carbon water pump 5, and the activated carbon in the activated carbon filter bin 105 is used to filter the water to remove pollutants such as organic matters, heavy metals, peculiar smells, and COD in the liquid, ensuring that the output meets the requirements. The clean water after being treated by the activated carbon filter bin 105 is directly transported to the sand filter tank 106 for sand filtration and then directly discharged as clean water from the clean water discharge port 34. And because the sand filter tank 106 is provided with a backwashing pump 22, when the activated carbon filter bin 105 needs to be backwashed later, the clean water in the sand filter tank 106 is pumped by the backwashing pump 22 and returned to the activated carbon filter bin 105 for backwashing operation. The sewage generated during the backwashing of the activated carbon filter bin 105 flows into the backwashing waste water tank 111. Since the amount of water is relatively large during the backwashing process of the activated carbon filter bin 105, it is necessary to add a backwashing waste water tank 111 for buffering. At the same time, the water in the backwashing waste water tank 111 is pumped into the spiral press 17 by the waste water supply pump 32. The sludge generated after being treated by the spiral press 17 flows into the garbage bin 38 through the sludge outlet 172. The water generated after being treated by the spiral press 17 is pumped into the sand filter tank 106 by the external supply pump 171 of the spiral press and directly discharged as clean water from the clean water discharge port 34 after sand filtration by the sand filter tank 106, 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 backwashing pump 22 from the sand filter tank 106 has three functions. One part returns to the activated carbon filter bin 105 for backwashing operation, one part flows into the medicine adding tank 109 through the water pumping pipeline 37 as the makeup water for the medicine adding tank 109, and the other part of the water is transported to the spray conveying pipe 162 through the high-pressure spray gun 161, and then the spray holes 15 are supplied with water by the spray pipe 141. Later, in order to be able to adjust the spray size of the spray conveying pipe 162, a spray valve with adjustable flow rate can be set on the spray conveying pipe 162 for control;

[0051] At the same time, when the water is not filtered later, the sludge at the bottom of the oil-water separation tank I 101 can be pumped by the slag pumping pump I 25 and sent into the rapid flocculation tank 108 through the sewage discharge pipe 23 to achieve the flocculation of the sludge, and the sludge at the bottom of the oil-water separation tank II 102 can be pumped by the slag pumping pump II 27 and sent into the rapid flocculation tank 108 through the sewage discharge pipe 23 to achieve the flocculation of the sludge.

[0052] It should be noted that in order to prevent the water in the slow flocculation tank 104 from overflowing, an overflow port can be provided on the side of the slow flocculation tank 104, and the water can be overflowed into the spiral press 17 through the overflow port. At the same time, in the later stage, cleaning ports can be provided at the bottoms of the first oil-water separation tank 101, the second oil-water separation tank 102, the third oil-water separation tank 103, the slow flocculation tank 104, the activated carbon filter bin 105, the sand filter tank 106, and the rapid flocculation tank 108, which is convenient for sewage discharge during the later cleaning of the interiors of the first oil-water separation tank 101, the second oil-water separation tank 102, the third oil-water separation tank 103, the slow flocculation tank 104, the activated carbon filter bin 105, the sand filter tank 106, and the rapid flocculation tank 108. It should be noted that in order to automatically open or close each connecting pipeline, control valves electrically connected to the control cabinet 35 can be provided on each connecting pipeline to automatically operate the opening or closing of each pipeline. As for how to set the control valves and how the control cabinet 35 controls the opening or closing of the control valves belongs to the conventional technology in this field, so no specific description will be given here.

[0053] Therefore, the following advantages are achieved through the present invention:

[0054] 1. This structure uses a spray heating drive mechanism to perform high-pressure spray flushing on the meshes of the conveyor mesh conveyor belt, avoiding the blockage of the meshes of the mesh conveyor belt by garbage and affecting the later solid-liquid separation effect, and the meshes of the mesh conveyor belt will not be blocked after long-term use;

[0055] 2. Moreover, this structure uses a conveyor mesh conveyor belt for solid-liquid filtration to convey the kitchen waste - i.e., swill, transported from the side water inlet, ensuring that the fluidity of the garbage becomes stronger, and the sewage treatment can be carried out continuously. When too much swill enters, it will not affect the filtration efficiency, and the entire oil-water separation process is more thorough and efficient;

[0056] 3. At the same time, high-pressure and high-temperature flushing is adopted. While further flushing the mesh garbage, the oil remaining in the meshes is also flushed at high temperature, avoiding the blockage of the meshes by the cooled oil and affecting the filtration effect;

[0057] 4. At present, the oil interceptor, as a pretreatment facility for the kitchen oil-containing sewage discharged from the catering industry and some residential areas, its core function is to effectively separate and intercept the oil and suspended solids in the wastewater, preventing them from being directly discharged into the urban drainage system, thereby protecting the water body from pollution. However, over time, a large amount of oil, food residues, and sludge will gradually accumulate inside the oil interceptor. These contaminants not only affect the separation effect of the oil interceptor but also may become a breeding ground for bacteria, posing a serious threat to the surrounding environmental hygiene. Moreover, if the treatment of the oil interceptor is not in place, there will be multiple pollutions, and there will also be the generation of wastewater, waste gas, odor, and garbage. By applying the present invention to mobile vehicle-mounted equipment, compared with the existing operation using an oil interceptor, it can solve the problem of secondary pollution of the oil interceptor;

[0058] 5. It can also solve the problem that the proportion of labor cost is too large, because at present, most catering kitchens collect the kitchen waste generated by restaurants simply by manual cleaning, and the labor cost is too high.

[0059] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made thereto all fall within the protection scope of the present invention.
