[0002] Industrial wastewater refers to wastewater and waste liquid generated during industrial production. It contains industrial raw materials, intermediate products, by-products, and pollutants that are lost with the water. Large amounts of oil-water mixtures are often generated in industrial production. If these large amounts of oil-water mixtures are discharged directly without treatment, they will cause serious environmental pollution.

[0004] In practical use, the aforementioned patent uses a filter basket to pre-intercept solid impurities in wastewater to prevent impurities from entering subsequent separation units and causing pipe blockage or equipment wear. However, as impurities accumulate, the pores of the filter basket gradually become clogged, leading to increased water flow resistance and reduced wastewater flow speed, which in turn affects the overall treatment efficiency. Therefore, we need to propose an oil-water separation device for industrial wastewater treatment. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: An oil-water separation device for industrial wastewater treatment includes: a treatment tank 1; a U-shaped support frame 2, fixedly installed inside the treatment tank 1; a filter assembly 3 for pre-intercepting and filtering impurities in the wastewater, and the filter assembly 3 is installed on the U-shaped support frame 2; and a cleaning assembly 4 for timely cleaning of impurities on the surface of the filter assembly 3, and the cleaning assembly 4 is disposed inside the treatment tank 1.

[0019] With the arrangement of treatment box 1, U-shaped support frame 2, filter assembly 3 and cleaning assembly 4, the U-shaped support frame 2 provides stable support for filter assembly 3, and the filter assembly 3 and U-shaped support frame 2 are detachably installed for easy maintenance and replacement. As a pretreatment unit, filter assembly 3 can intercept particulate impurities in wastewater to prevent them from entering the subsequent separation process and causing blockage or efficiency reduction. The cleaning assembly 4 automatically removes impurities from the surface of filter assembly 3 by mechanical means, maintains filtration efficiency, reduces manual intervention, and extends the service life of filter assembly 3.

[0020] The cleaning component 4 includes a support plate 41, an electric push rod 42, a scraper 43, and two sets of guide rods 44. The support plate 41 is fixedly installed on one side of the treatment box 1, the electric push rod 42 is fixedly installed on the top of the support plate 41, and the telescopic end of the electric push rod 42 passes through the treatment box 1 and is fixedly connected to one side of the scraper 43. The two sets of guide rods 44 are respectively fixedly installed on one side of the scraper 43, and both sets of guide rods 44 are slidably arranged inside the treatment box 1. The bottom of the scraper 43 is in contact with the top of the filter component 3.

[0021] With the support plate 41, electric push rod 42, scraper 43, and two sets of guide rods 44, the support plate 41 provides stable support for the electric push rod 42, ensuring the stability of its telescopic movement. The electric push rod 42 can be a Taiwan APL linear transmission waterproof electric push rod. The electric push rod 42 serves as a power source and is electrically connected to the controller. This is existing technology and will not be elaborated on here. The reciprocating telescopic movement is controlled by the controller. Its travel distance matches the width of the filter assembly 3, and the scraper 43 keeps in close contact with the filter screen 31, thereby ensuring the cleaning effect. The two sets of guide rods 44 ensure the accuracy of the scraper 43's movement trajectory and prevent deviation.

[0022] Specifically, the filter assembly 3 includes a filter screen 31 and two sets of filter baskets 32; the filter screen 31 is installed on the top of the U-shaped support frame 2, and the two sets of filter baskets 32 are fixedly connected to both sides of the filter screen 31.

[0023] With the filter screen 31 and two sets of filter baskets 32, the filter screen 31 is located directly below the feed pipe, which can effectively intercept solid impurities in the sewage. The filter baskets 32 on both sides are used to collect impurities pushed by the scraper 43. The scraper 43 pushes the impurities away from the filter screen 31 body to the basket area, effectively maintaining the permeability of the main filtration area and ensuring the continuous and stable filtration efficiency of the filter screen 31.

[0024] In a further preferred embodiment, a separation component 5 is also included for separating oil and water in the filtered wastewater, and the separation component 5 is located below the filter component 3.

[0025] By setting up the separation component 5, the filtered wastewater can flow naturally into the separation zone. The separation process does not require additional power and is completed by gravity, which is both energy-saving and reliable.

[0026] Specifically, the separation component 5 includes a first isolation membrane 51, a second isolation membrane 52, an oil storage chamber 53, a water storage chamber 54, an oil drain pipe 55, and a drain pipe 56. The first isolation membrane 51 and the second isolation membrane 52 are both fixedly installed inside the processing tank 1. The oil storage chamber 53 is located on one side of the first isolation membrane 51, and the water storage chamber 54 is located on the other side of the first isolation membrane 51. The oil drain pipe 55 is connected to the bottom of the oil storage chamber 53, and the drain pipe 56 is connected to the bottom of the water storage chamber 54.

[0027] With the arrangement of the first isolation membrane 51, the second isolation membrane 52, the oil storage chamber 53, the water storage chamber 54, the oil drain pipe 55, and the drain pipe 56, the first isolation membrane 51 and the second isolation membrane 52 are made of oleophilic and hydrophobic or hydrophilic and oleophobic polymer materials, and have a microporous structure on their surface, allowing a specific phase to pass through while blocking another phase. The oil is blocked by the isolation membrane and remains in the oil storage chamber 53, while the water passes through the isolation membrane into the water storage chamber 54 and is then discharged through the drain pipe 56. After the sewage is discharged, the solenoid valve on the oil drain pipe 55 is opened to discharge the oil in the oil storage chamber 53 through the oil drain pipe 55. The solenoid valve is existing technology and is electrically connected to the controller, which will not be described in detail here.

[0028] The first isolation membrane 51 is inclined, and one end of the first isolation membrane 51 is fixedly connected to the top end of the second isolation membrane 52.

[0029] The inclined first isolation membrane 51 increases the separation area of ​​the wastewater and improves the treatment efficiency. The connection between the first isolation membrane 51 and the second isolation membrane 52 forms a continuous separation channel, which enables the oil-water mixture to be fully separated.

[0030] Specifically, a first guide block 6 is fixedly installed at the bottom of the oil storage cavity 53, and the first guide block 6 is inclined.

[0031] By setting the first guide block 6, the oil phase at the bottom of the oil storage chamber 53 can flow smoothly into the oil drain pipe 55, avoiding residue.

[0032] The water storage cavity 54 has a second guide block 7 fixedly installed at its inner bottom, and the second guide block 7 is inclined.

[0033] By setting the second guide block 7, similar to the first guide block 6, the water phase in the water storage chamber 54 is guided to flow to the drain pipe 56, ensuring the rapid discharge of sewage.

[0034] Working principle: When this utility model is used, sewage first enters the treatment tank 1 through the feed pipe at the top of the treatment tank 1, and then passes through the filter screen 31 installed on the U-shaped support frame 2 to intercept and filter particulate impurities in the sewage. At the same time, the electric push rod 42 is activated. When the electric push rod 42 extends, the scraper 43 pushes the impurities into one set of filter baskets 32. When the electric push rod 42 retracts, the scraper 43 moves in the opposite direction and pushes the impurities into another set of filter baskets 32. This process can continuously remove impurities from the filter screen 31 to ensure that the filtration channel is unobstructed. The residual wastewater in the impurities accumulated in the filter basket 32 ​​continues to be filtered through the mesh basket. The filtered wastewater enters the separation component 5. The separation component 5 achieves oil-water separation through the inclined first isolation membrane 51 and second isolation membrane 52. The oil is blocked by the isolation membrane and remains in the oil storage chamber 53, while the water passes through the isolation membrane into the water storage chamber 54 and is then discharged through the drain pipe 56. After the sewage is discharged, the solenoid valve on the oil drain pipe 55 is opened to discharge the oil in the oil storage chamber 53 through the oil drain pipe 55.
