Description

Technical Field

[0001] This invention relates to the field of inclined plate oil separation technology, and more particularly to an inclined plate oil separation device for anaerobic fermentation of kitchen waste. Background Technology

[0002] Inclined plate grease traps are a process that removes oil from oily wastewater to meet discharge standards. Inclined tube grease traps consist of a set of inclined plates or tubes within the tank, ensuring uniform water flow to improve oil removal efficiency and reduce tank volume. The oil content in the effluent can be reduced to 50 mg / L. The oily wastewater enters a sludge removal basket, where large particles quickly settle and are trapped. The filtered wastewater then enters the second treatment chamber, where it undergoes multiple layers of filtration through stainless steel inclined tubes. The oil quickly separates to the surface, and as the volume increases, more oil accumulates, eventually flowing out through a semi-sectioned stainless steel floating oil outlet. In the third treatment chamber, the water quality is stabilized, and the floating oil is further removed. Simultaneously, the wastewater enters a stainless steel filter plate with sludge removal holes for further filtration, removing fine particles (mainly suspended particles). The wastewater then flows upwards through the various inlets at its lower end into the fourth treatment chamber—the discharge zone—where it flows out slowly.

[0003] Authorization announcement number CN202122765145.9 discloses an inclined plate oil separator, which, through an oil separator component and a filter component, allows wastewater to be discharged into the second housing through an inlet pipe. The wastewater first passes through a first filter plate to filter larger solid waste, and then a second filter plate to filter smaller solid waste. When a first motor drives a cam to rotate, the cam's protrusion contacts the second filter plate, creating vibration to minimize wastewater retention on the surfaces of the first and second filter plates. The wastewater then flows onto a corrugated plate, passing through parallel channels formed between the plates. Due to buoyancy, oil droplets rise and are discharged from the first housing through an oil outlet pipe. The separated wastewater is discharged through a first outlet pipe. This device enhances filtration, facilitates filtration, improves the quality of oil-sludge separation, and thus improves practicality. However, this device has the following problems: First, there is no subsequent steam cleaning, and the temperature cannot be controlled, which can easily cause the floating oil in the tank to freeze. Second, the inclined plates are not cleaned properly, resulting in a short service life. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by incorporating a sandwich structure for the filter inclined plate, incorporating heating wires within the sandwich structure, and utilizing spray nozzles on the left and right sides of the inclined box to solve the technical problems of uncontrollable temperature, floating oil condensation, and inadequate cleaning.

An I-shaped support frame is fixedly connected to the lower right side of the upper housing, and the I-shaped support frame has identical connecting gaskets at both the front and rear of its lower end.

[0011] As a preferred embodiment, the left side of the upper chamber is provided with a pair of identical circulation pipes, which are distributed front to back, with their upper ends both penetrating and connecting to the water outlet trough, and their lower ends penetrating and connecting to the lower chamber. The lower chamber is provided with a stainless steel water collection pipe, one side of which is fixedly connected to the circulation pipe, and the stainless steel water collection pipe has micro-holes. The upper end of the upper chamber is provided with a sealing movable cover plate.

[0012] As a preferred embodiment, the filter inclined plate has a sandwich structure, and heating wires are uniformly arranged inside the filter inclined plate. A filter screen is provided inside the filter hole, and the filter hole is not connected to the internal sandwich of the filter inclined plate.

[0013] As a preferred embodiment, the filter inclined plate is a polyester fiberglass corrugated inclined plate, and the filter inclined plate is distributed at an angle of 60 degrees. Spray nozzles are evenly provided on both the left and right sides of the inner wall of the inclined box. The spray nozzles on the left side are evenly distributed parallel to the horizontal plane, and the spray nozzles on the right side are evenly distributed at an angle of 150 degrees.

[0014] As a preferred embodiment, a lifting frame is fixedly connected to the left side of the lower housing, and an auxiliary support column is fixedly connected to the right side of the lower housing. A ladder is provided at the center of the lifting frame and the inclined plate oil-separating structure. Handrails are provided on both sides of the ladder. The left handrail is fixedly connected to the lifting frame, and the right handrail is fixedly connected to the upper housing. Galvanized pipes are evenly arranged between the handrails. The left side of the galvanized pipe is fixedly connected to the left handrail, and the right side of the galvanized pipe is fixedly connected to the right handrail.

[0015] As a preferred embodiment, the lower left side of the flocculation reaction tank is provided with a feeding pipe, and the right side of the feeding pipe is connected to the water outlet trough. The water outlet trough is provided with a slag removal basket. The slag removal basket is a rectangular frame with an open top surface, and the surface of the slag removal basket is uniformly provided with filter slag holes. The feeding pipe is connected to the slag removal basket.

[0016] As a preferred embodiment, the right side of the sealing movable cover is fixedly connected to the upper housing, and the left side of the sealing movable cover is a movable plate, with the left movable plate hinged to the right side of the sealing movable cover.

[0017] As a preferred embodiment, a mud-water diversion plate is fixedly connected to the lower end of the upper box, a heater is provided on the lower right side of the mud-water diversion plate, a protective cover is provided on the heater, and the right side of the protective cover is fixedly connected to the inner wall of the upper box.

[0018] As another preferred embodiment, the mud-water diversion plate is a heat-conducting metal plate.

[0019] The beneficial effects of this invention are:

[0020] (1) In this invention, by setting up a filter inclined plate, the filter inclined plate is set as a sandwich, and a heating wire is set in the sandwich. The upper and lower ends of the filter inclined plate are fixedly connected to the frame of the inclined box. The frame at the upper and lower ends of the inclined box is a sandwich. In this way, the internal space of the filter inclined plate and the upper and lower ends of the inclined box can be interconnected. In this way, the circuit can be connected through the sandwich space, so that the external heating mechanism can ensure that the filter inclined plate has a heating function, making the internal temperature uniform and preventing the phenomenon of floating oil freezing, thus ensuring the efficiency of oil-water separation.

[0021] (2) In this invention, spray nozzles are set on the left and right sides of the inclined box. The left and right sides of the inclined box are sandwiched structures, so rubber tubes can be set in the sandwich and connected to the spray nozzles. Water is introduced into the spray nozzles from the rubber tubes through an external water source. Then the spray nozzles are aligned with the inclined filter plate for rinsing. The different angles of the left and right sides of the spray nozzles ensure that there are no dead corners in the cleaning. In addition, a filter screen is set in the filter hole, so that the cleaning will not be incomplete due to solid particles blocking the filter hole.

[0022] (3) In this invention, by setting up a slag removal basket and using a through pipe to connect the slag removal basket, the waste liquid coming out of the flocculation reaction tank first passes through the slag removal basket for the first filtration, and then enters the inclined box below for oil separation treatment, ensuring that large particles of solid slag will not affect the overall oil-water separation. Moreover, the setting of a sealed movable cover plate can prevent fire and the impact of oil and gas on atmospheric pollution.

[0023] In summary, this equipment has the advantages of simple principle, heating the interior to prevent floating oil from freezing and cleaning without dead corners, and is especially suitable for the field of inclined plate oil separation technology. Attached Figure Description

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figures 1 to 5 As shown, the present invention provides an anaerobic fermentation inclined plate oil separator for kitchen waste, including a flocculation reaction tank 1. The upper right end of the flocculation reaction tank 1 is provided with a through pipe 11, and the right side of the through pipe 11 is connected to the inclined plate oil separator structure 2. The lower end of the flocculation reaction tank 1 is provided with a lifting frame 3, and the right side of the lifting frame 3 is fixedly connected to the outer surface of the inclined plate oil separator structure 2.

[0033] The inclined plate oil separator structure 2 includes an upper box 21, an inclined box 22, and a lower box 23. The upper box 21 has a water outlet 211 on the left side inside, and a water inlet 212 on the left end face of the upper box 21. The upper box 21 has a water outlet 213 on the left rear end face of the upper box 21. The water inlet 212 and the water outlet 213 both penetrate the upper box 21 and connect to the water outlet 211.

[0034] The inclined box 22 has a sandwich structure on the left and right sides, and the inclined box 22 is uniformly provided with filter inclined plates 221 inside. The front and rear ends of the filter inclined plates 221 are fixedly connected to the inner wall of the inclined box 22, and filter holes 222 are uniformly opened on the filter inclined plates 221.

[0035] The lower box 23 has a trapezoidal cross-section, and its lower end is fixedly connected to the mud discharge pipe 231, which is connected to the interior of the lower box 23.

[0036] Furthermore, such as Figure 3 As shown, the upper housing 21 has an oil outlet groove 201 on the right side inside, and an oil outlet 202 at the rear of the upper housing 21. The oil outlet 202 passes through the upper housing 21 and connects to the oil outlet groove 201. The lower end of the right side of the upper housing 21 is fixedly connected to the I-shaped support frame 4. The lower end of the I-shaped support frame 4 is provided with the same connecting gasket 41 at both the front and rear. The I-shaped support frame 4 is used to support the inclined plate oil separation structure 2 on the right side, so that the stability of the whole device is better. There is a layer of rubber material on the underside of the gasket 41, which can effectively reduce vibration and prevent the vibration of other devices in the working room from affecting the installation angle of the spray nozzle 223 of this device during operation.

[0037] The oil outlet 201 and oil outlet 202 are used to collect and output the grease separated from the oil, ensuring the function of the inclined plate in separating oil and improving the efficiency of grease collection.

[0038] Furthermore, a pair of identical circulation pipes 214 are provided on the left side of the upper housing 21. The circulation pipes 214 are distributed front to back, with their upper ends both penetrating and connecting to the water outlet 211, and their lower ends penetrating and connecting to the lower housing 23. A stainless steel water collection pipe 215 is provided inside the lower housing 23. The stainless steel water collection pipe 215 is fixedly connected to the circulation pipes 214 on one side, and micro-holes are opened on the stainless steel water collection pipe 215. A sealing movable cover plate 216 is provided at the upper end of the upper housing 21, connecting the upper end of the circulation pipe 214 to the water outlet 211 and the lower end to the lower housing 23. Granular impurities will accumulate inside body 23, and wastewater will appear in outlet tank 211. The wastewater is then recirculated into lower tank 23. Due to the presence of the sealing movable cover plate 216, the entire inclined plate oil-separating structure 2 is in a sealed state, so biogas is generated under anaerobic conditions. The microbubbles of biogas rise continuously, causing the oil and water in inclined tank 22 to surge, ensuring that the oil floats more thoroughly and the separation is more efficient. The wastewater in circulation pipe 214 is evenly discharged through stainless steel water collection pipe 215, making the wastewater rise more evenly, thereby carrying more sludge and oil through the filter inclined plate 221.

[0039] Furthermore, such as Figure 5 As shown, the filter inclined plate 221 has a sandwich structure, and heating wires are evenly arranged inside the filter inclined plate 221. A filter screen is provided inside the filter hole 222, and the filter hole 222 is not connected to the internal sandwich structure of the filter inclined plate 221. Heating wires can be placed inside the sandwich structure of the filter inclined plate 221, so that the entire filter inclined plate 221 can be heated. This prevents grease from freezing when it comes into contact with the filter inclined plate 221. Moreover, the evenly arranged filter inclined plates 221 can increase the temperature of the entire box of the inclined plate oil separation structure 2, ensuring that the grease will not freeze and become unseparable due to low temperature, and also preventing grease from condensing on the filter inclined plate 221, thus ensuring the filtration and separation effect of the filter inclined plate 221.

[0040] The filter hole 222 is a hole cut out in a rectangular hollow inclined plate. A filter screen is also installed inside the filter hole 222. When the waste liquid of kitchen waste passes through the filter inclined plate 221, it can intercept the floating sludge particles. Moreover, due to the heating effect of the filter inclined plate 221 itself, the filter screen will also have a temperature, so it will not intercept grease. The filter screen is made of non-oil-repellent material to ensure that grease will not stick to the filter screen.

[0041] Furthermore, the filter inclined plate 221 is a polyester fiberglass corrugated inclined plate, and the filter inclined plate 221 is distributed at a 60-degree angle. Spray nozzles 223 are evenly provided on both the left and right sides of the inner wall of the inclined box 22. The spray nozzles 223 on the left side are evenly distributed parallel to the horizontal plane, and the spray nozzles 223 on the right side are evenly distributed at a 150-degree angle. The polyester fiberglass corrugated inclined plate is made of a non-oleophilic material, which can effectively prevent oily substances from adhering to the inclined plate. The filter inclined plate 221 is distributed at a 60-degree angle to the horizontal plane, and the left spray nozzle 223 is evenly distributed parallel to the horizontal plane. The spray nozzles are arranged in parallel, with the right spray nozzle 223 at a 150-degree angle to the horizontal plane, i.e., installed perpendicular to the filter inclined plate 221. This ensures that there are no dead angles when spraying the filter inclined plate 221. In addition, a heating wire is installed inside the filter inclined plate 221. When clean water comes into contact with the filter inclined plate 221 from the spray nozzle 223, a certain amount of steam will be generated. Because the inclined plate is made of a non-oil-repellent material, some grease will inevitably adhere to the inclined plate. Therefore, oil will accumulate on the filter inclined plate 221 over a long period of time. It should be cleaned regularly with steam and clean water to prevent blockage between the inclined plates.

[0042] Furthermore, such as Figure 1 As shown, the lower box 23 is fixedly connected to the left side of the outer side of the lifting frame 3 and the lower box 23 is fixedly connected to the right side of the outer side of the auxiliary support column 232. The lifting frame 3 and the inclined plate oil separator 2 are provided with a ladder 5. The ladder 5 is provided with handrails 51 on the left and right sides. The left handrail 51 is fixedly connected to the lifting frame 3 and the right handrail 51 is fixedly connected to the upper box 21. Galvanized pipes 52 are evenly arranged between the handrails 51. The left side of the galvanized pipe 52 is fixedly connected to the left handrail 51 and the right side of the galvanized pipe 52 is fixedly connected to the right handrail 51. The lifting frame 3 and the auxiliary support column 232 are used to support and install the flocculation reaction tank 1 and the inclined plate oil separator 2, raising the height of the overall device to ensure that the sludge discharge port of the lower box 23 can normally discharge large particles of sediment impurities due to sedimentation.

[0043] The ladder 5 is provided to facilitate observation by staff. Since the sealed movable cover 216 can be opened, staff can use the ladder 5 to reach the top during subsequent cleaning of the inclined plate oil separator structure 2, and then clean the entire device structure, thus extending the service life of the entire device.

[0044] Furthermore, such as Figure 3As shown, the lower left end of the flocculation reaction tank 1 is provided with a feeding pipe 12, and the right side of the through pipe 11 is connected to the outlet tank 211. The outlet tank 211 is provided with a slag removal basket 13. The slag removal basket 13 is a rectangular frame with an open upper end, and the surface of the slag removal basket 13 is uniformly provided with filter slag holes. The through pipe 11 is connected to the slag removal basket 13. The waste liquid after the flocculation reaction in the flocculation reaction tank 1 enters the outlet tank 211 and is filtered by the slag removal basket 13 to remove suspended particulate impurities. Because the upper box 21 is connected to the inclined box 22, the temperature inside the upper box 21 will also rise. This will prevent grease from freezing and affecting the slag removal effect of the slag removal basket 13. The principle is simple and the practicality is strong.

[0045] Furthermore, such as Figure 1 As shown, the right side of the sealing movable cover 216 is fixedly connected to the upper box 21, and the left side of the sealing movable cover 216 is a movable plate. The left side of the movable plate is hinged to the right side of the sealing movable cover 216. The sealing movable cover 216 can prevent fire and the impact of oil and gas on atmospheric pollution, and can also effectively seal the anaerobic reaction, using biogas to churn the internal liquid, making the oil separation more thorough, simple and efficient. Moreover, the left side is set as a movable plate, and the lower end of the movable plate is a water outlet trough 211. The slag removal basket 13 is placed in the water outlet trough 211. The movable plate can be opened to clean the slag removal basket 13, extending the service life of the entire device.

[0046] Furthermore, such as Figure 4 As shown, a mud-water diversion plate 217 is fixedly connected to the lower end of the upper box 21. A heater 218 is provided on the lower right side of the mud-water diversion plate 217. A protective cover 219 is provided on the heater 218. The right side of the protective cover 219 is fixedly connected to the inner wall of the upper box 21. The mud-water diversion plate 217 is to prevent the separated oil droplets and sludge from being carried away by the water flow. The heater 218 prevents grease from condensing and facilitates cleaning.

[0047] Furthermore, such as Figure 4 As shown, the mud-water diversion plate 217 is a heat-conducting metal plate. Using a metal plate with good thermal conductivity as the mud-water diversion plate 217 can make the temperature of the entire mud-water diversion plate 217 rise when the heater 218 starts working, thus preventing the grease from freezing.

[0048] Working process: First, the kitchen waste wastewater to be treated is fed into the flocculation reaction tank 1 through the feed pipe 12. By adding flocculant into the flocculation reaction tank 1, a flocculation reaction occurs inside, and some impurities are precipitated. Then, the waste liquid from the flocculation reaction enters the inclined plate oil separator structure 2 through the feed pipe 11. It first passes through the slag removal basket 13 and then enters the upper box 21. Under the action of gravity, it enters the inclined box 22 and then the lower box 23. During this process, the grease is blocked by the filter inclined plate 221 and floats to the oil outlet. The particulate impurities settle into the lower box 23 with gravity.

[0049] In addition, the filter inclined plate 221 is equipped with a heating wire, so the filter inclined plate 221 can control the temperature rise of the entire inclined box 22 to prevent the temperature from being too low and the grease from freezing. Furthermore, the spray nozzle 223 sprays clean water onto the filter inclined plate 221. The spray nozzles 223 on the left and right sides are set at different angles, so that the filter inclined plate 221 can be sprayed without dead angles. The principle is simple and the practicality is strong.

[0050] In summary, the entire device effectively recovers grease using the inclined plate oil-separating structure 2, prevents grease from freezing using the heating wire, and the spray nozzle 223 sprays and cleans the inclined filter plate 221, and can also react with the inclined filter plate 221 to generate steam, making the cleaning of the inclined filter plate more thorough.
