Description

Technical Field

[0001] The utility model relates to the technical field of oil-water separation, in particular to a kitchen oil-water separation device. Background Technique

[0002] If the oil-water generated in the kitchen is directly discharged, it will pollute the sewer and municipal pipe network, and then cause pollution to natural water bodies such as rivers and lakes. Moreover, the kitchen wastewater contains a large amount of grease. If the oil-water separation is not carried out, the grease will condense in the pipeline, resulting in pipeline blockage, increasing the cleaning cost and maintenance difficulty. Therefore, in some catering industries and food processing industries, the wastewater containing a large amount of grease will be subjected to oil-water separation to prevent the grease from entering the sewer system and causing blockage and environmental pollution.

[0003] Common oil-water separation equipment includes oil interceptor, etc. By using the density difference between oil and water, the oil floats to the water surface through gravity separation, and then it is collected and removed by mechanical or manual means. The oil interceptor is generally divided into multiple areas, and a residue basket is set in the initial area to filter the food residues entering the oil interceptor. However, the residue basket can only filter some larger residues, but some fine particles or tiny impurities broken under the action of water flow may still pass through the residue basket and gradually deposit at the bottom of the oil interceptor. If not cleaned regularly, the effective volume inside the oil interceptor will be reduced after long-term use, reducing the treatment capacity of the oil-containing wastewater. And because the oil interceptor is generally buried underground, it is inconvenient to clean the impurities deposited at the bottom of the oil interceptor. Content of the Utility Model

[0004] The utility model provides a kitchen oil-water separation device to solve the problem that smaller impurities are likely to accumulate at the bottom of the existing oil interceptor and are not easy to clean.

[0005] The technical problems solved by the utility model are realized by the following technical solutions:

[0006] A kitchen oil-water separation device includes an oil interceptor. Inside the oil interceptor, there are oil separation plates and a barrier plate. The barrier plate divides the inside of the oil interceptor into at least two isolation chambers. And a residue basket is provided in the isolation chamber at the input pipe of the oil interceptor, and a deep filtration baffle is provided in the isolation chamber at the output pipe of the oil interceptor. The inner wall of the bottom of the isolation chamber is provided with an inclined slag discharge plate. A spray pipe passing through the oil separation plates and the barrier plate is rotatably connected inside the oil interceptor. A number of spray nozzles are provided on the spray pipe. A water storage chamber is provided on the outer periphery of the oil interceptor. The water storage chamber is communicated with the spray pipe through a water delivery pipe, and a water pump is provided on the water delivery pipe.

[0007] Preferably, a water inlet pipe is communicated between the output pipe of the oil interceptor and the water storage chamber, and a first valve is provided on the water inlet pipe.

[0008] Preferably, an electric heating element is provided inside the water storage chamber.

[0009] Preferably, a sewage discharge pipe is provided on the isolation chamber, and the input end of the sewage discharge pipe is located at the lowest side of the slag discharge plate. An outlet slag pipe is communicated with the output end of the sewage discharge pipe, and a second valve is provided on the sewage discharge pipe.

[0010] Preferably, a filling pipe for filling cleaning liquid is provided on the water storage chamber.

[0011] Preferably, a driving member is provided on the outer wall of the oil separation tank, and the output shaft of the driving member is connected to one end of the spray pipe for driving the spray pipe to rotate reciprocally.

[0012] The beneficial effects of the present utility model are as follows: Under the action of the inclined setting of the slag discharge plate, impurities are naturally caused to flow towards the lowest point of the isolation chamber under the action of gravity, reducing the residue and accumulation of impurities at the bottom of the oil separation tank. Moreover, the inclined slag discharge plate is washed by the spray pipe above, so that the washing water flow can flow more smoothly along the plate surface of the slag discharge plate, covering a larger area, improving the washing efficiency and cleaning degree, thereby keeping the inside of the oil separation tank clean, helping to improve the separation effect of oil and water, and enabling the oil separation tank to better play its function.

Detailed implementation mode

[0019] In order to make the technical means, creative features, achieved purposes and functions realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific illustrations.

[0020] Referring to Figures 1 - 4 As shown, a kitchen oil-water separation device includes an oil separation tank 1. Inside the oil separation tank 1, there are an oil separation plate 11 for blocking oil stains and a baffle plate 12 for slowing down the water flow rate. There are certain gaps between the oil separation plate 11 and the baffle plate 12 and the bottom and top of the oil separation tank 1 respectively for water flow to pass through. The baffle plate 12 divides the inside of the oil separation tank 1 into at least two isolation chambers 2. The number of baffle plates 12 is not limited and can be set according to the specifications of the oil separation tank 1 and the amount of sewage to be treated to achieve the best oil separation effect and operating efficiency. And a residue basket 21 is provided in the isolation chamber 2 at the input pipe of the oil separation tank 1, and a deep filtration baffle 22 is provided in the isolation chamber 2 at the output pipe of the oil separation tank 1. The lower end of the deep filtration baffle 22 is open to prevent the upper layer of oil liquid from being discharged from the output pipe of the oil separation tank 1. During use, the oil separation tank 1 can be buried at the output end of the kitchen sewage discharge pipe 8, so that the external sewage discharge pipe 8 is connected to the input pipe of the oil separation tank 1. The kitchen waste water entering the oil separation tank 1 will first enter the residue basket 21. The residue basket 21 filters and intercepts the solid impurities in the kitchen waste water to prevent the downstream drainage pipeline from being blocked. By using the density difference between oil and water, the oil floats to the water surface through gravity separation, while the water flows through the bottom channel to the output pipe of the oil separation tank 1 and is discharged. In order to promote the flow of the oil-water mixture in the oil separation tank 1, a suction device can be provided on the output pipe of the oil separation tank 1 to promote the discharge of the oil-water mixture in the oil separation tank 1. An oil discharge pipe 14 connected to the oil separation tank 1 is provided above the output pipe of the oil separation tank 1 for discharging the separated oil liquid. A cover plate 13 is also provided above the oil separation tank 1. By regularly removing the cover plate 13, the food residues filtered in the residue basket 21 can be cleaned. The above is the prior art, and those skilled in the art should know it and will not be described in detail here. However, since the residue basket 21 can only filter some larger residues, some fine particles or tiny impurities broken under the action of water flow may still pass through the residue basket 21. Over time, sediment will accumulate inside the oil separation tank 1, and since the oil separation tank 1 is buried underground, it is not easy to clean. Based on the above problems, the present utility model makes the following improvements:

[0021] Specifically, a slag discharge plate 3 is provided on the inner wall of the bottom of the isolation chamber 2 and is inclined. Tiny impurities that are not filtered by the residue basket 21 settle on the slag discharge plate 3, and the slag discharge plate 3 with a certain inclination angle causes the impurities to flow naturally to the lowest point in the isolation chamber 2 under the action of gravity, reducing the residue and accumulation of impurities at the bottom of the oil separation tank 1. At the same time, in order to improve the cleaning effect of the tiny impurities on the slag discharge plate 3, a spray pipe 4 is rotatably connected inside the oil separation tank 1. A number of spray nozzles 41 are provided on the spray pipe 4, and the spray pipe 4 respectively penetrates through the oil separation plate 11, the partition plate 12 and the deep filtration baffle 22. A water storage chamber 5 is provided on the outer periphery of the oil separation tank 1, and the water storage chamber 5 is communicated with the spray pipe 4 through a water delivery pipe 51. A water pump 52 is provided on the water delivery pipe 51. The input end of the water delivery pipe 51 extends into the interior of the spray pipe 4 and is hermetically and rotatably connected to the spray pipe 4. During regular cleaning, first, the oil and water in the oil separation tank 1 are drained, and then the liquid in the water storage chamber 5 is pumped by the water pump 52 and sprayed out through the spray nozzles 41 to wash the slag discharge plate 3, making the tiny impurities attached to the slag discharge plate 3 more likely to fall off, so as to facilitate the cleaning of the sediment impurities inside the bottom of the oil separation tank 1 without the need for manual entry into the tank for cleaning.

[0022] Further, referring to Figure 2 and Figure 4 As shown, a sewage discharge pipe 8 is provided on the isolation chamber 2, and the input end of the sewage discharge pipe 8 is located at the lowest side of the slag discharge plate 3, so that the impurities on the slag discharge plate 3 can move as close as possible to the input end of the sewage discharge pipe 8. An out slag pipe 81 is communicated with the output end of the sewage discharge pipe 8, and a second valve 82 is provided on the sewage discharge pipe 8. When the second valve 82 is opened, the water flow sprayed by the spray pipe 4 will drive the residue to flow into the out slag pipe 81 through the sewage discharge pipe 8 and be discharged uniformly. The sewage discharge pipe 8 can be communicated with an external special pipeline for subsequent unified treatment of the discharged stains.

[0023] Further, referring to Figure 2 As shown, a driving member 42 is provided on the outer wall of the oil separation tank 1. The output shaft of the driving member 42 is connected to one end of the spray pipe 4 for driving the spray pipe 4 to rotate reciprocally. The driving member 42 can be a servo motor or other equipment that can drive the spray pipe 4 to swing reciprocally, so that the water flow sprayed by the spray nozzles 41 can spray the slag discharge plate 3 comprehensively, reducing the occurrence of spray dead corners. Among them, a protective cover (not shown in the figure) can also be provided on the outer wall of the oil separation tank 1 for protecting the water pump 52 and the driving member 42 to avoid damage to the water pump 52 or the driving member 42 when buried below the ground surface.

[0024] Further, referring to Figure 2As shown in the figure, a water inlet pipe 6 is connected between the output pipe of the oil separation tank 1 and the water storage cavity 5. A first valve 61 is provided on the water inlet pipe 6. After the first valve 61 is opened, the separated sewage discharged from the output pipe of the oil separation tank 1 can enter the water storage cavity 5 through the water inlet pipe 6 for temporary storage, and be used as spray water to wash the slag discharge plate 3, so as to be reused and reduce the waste of water resources.

[0025] Further, referring to Figure 3 As shown in the figure, in order to prevent the grease from easily solidifying and adhering to the inner wall of the oil separation tank 1 in a low-temperature environment, an electric heating element 7 is provided inside the water storage cavity 5 to heat the washing liquid in the water storage cavity 5. The electric heating element 7 can be a tubular heater, a ceramic heating element, etc. By heating the liquid in the water storage cavity 5 and using water as the heat conduction medium to heat the oil separation tank 1, the fluidity of the grease can be maintained, the risk of grease blockage can be reduced, the separation effect can be improved, and the water storage cavity 5 is wrapped around the outer wall of the oil separation tank 1, which can improve the heating uniformity of the oil-water mixture in the oil separation tank 1.

[0026] Among them, the electric heating element 7, the first valve 61 and the second valve 82 can all be controlled to open and close through an external controller.

[0027] Further, referring to Figure 1 As shown in the figure, a filling pipe 9 for filling the cleaning liquid is provided on the water storage cavity 5, and the input end of the filling pipe 9 is located above the ground and is threadedly connected with a cap. When the slag discharge plate 3 is not washed with the waste water separated in the oil separation tank 1, a liquid containing a cleaning agent, such as some alkaline, acidic or surfactant, etc., can also be added to the water storage cavity 5 through the filling pipe 9, so that the deposited impurities are more easily decomposed and removed, and the cleaning effect is better.
