[0013] Beneficial effects

[0014] This invention provides an oil-water separation device that facilitates the replacement of the oil-water separation membrane. Compared with the prior art, it has the following advantages:

[0015] 1. This oil-water separation device, which facilitates the replacement of the oil-water separation membrane, uses adjustable and separating components within the device to allow the first three-way valve, feed pipe, two sets of guide pipes, and filter elements to cooperate and switch the direction of the mixed liquid introduction. The device achieves oil-liquid separation through the cooperation of two sets of housings, cover plates, infrared sensors, hydraulic cylinder assemblies, mounting frames, bellows, anti-detachment blocks, docking rings, membranes, the first valve, and ultrasonic sensors.

[0024] See Figures 1-4 This utility model provides the following two technical solutions:

[0025] First embodiment: An oil-water separation device that facilitates replacement of the oil-water separation membrane, including a base 1, the base 1 is connected to a processing component for oil-water separation treatment, the processing component includes: an adjusting component 2, which is installed on the base 1 for wastewater direction adjustment treatment, the adjusting component 2 includes a first three-way valve 21 installed at the top of the middle part of the base 1, a set of conduits 23 are respectively installed on both sides of the first three-way valve 21, a filter element 24 is installed on the side of the conduits 23 away from the first three-way valve 21, and a feed pipe 22 is installed in front of the first three-way valve 21;

[0026] Two sets of separators 3 are connected to two sets of filters 24 for oil-water separation. The separator 3 includes two sets of housings 31 fixedly connected to the base 1. The two sets of housings 31 are connected to the two sets of filters 24. A cover plate 32 is installed on the top of the housing 31. A hydraulic cylinder assembly 34 is installed on the bottom of the housing 31. An installation part 35 is installed on the extended top end of the hydraulic cylinder assembly 34. A separation membrane assembly 36 is installed on the upper side of the installation part 35. The separation membrane assembly 36 includes a docking ring 361 connected to the installation part 35.

A first valve 37 for oil discharge is installed on the side of the housing 31 near the upper end of the installation part 35. An oil discharge pipe for oil discharge is installed on the side of the first valve 37.

[0027] Discharge component 4 is installed at the bottom of housing 31 for draining retained liquid; separation component 3 also includes an infrared sensor 33 installed on the top of cover plate 32 for oil level detection, an ultrasonic sensor 38 for oil detection in sewage is installed at the bottom of housing 31, and a second screw is installed on the edge of cover plate 32 for threaded connection with the top edge of housing 31; mounting component 35 includes a mounting frame 351 fixedly connected to the top extended end of hydraulic cylinder assembly 34 and slidably connected to the inside of housing 31, a docking groove is provided on the inner side of mounting frame 351 for slidably connecting to docking ring 361, an array of anti-detachment blocks 353 for preventing docking ring 361 from detaching is rotatably connected to the edge of mounting frame 351, and a bellows 352 fixedly connected to housing 31 is installed at the bottom of mounting frame 351 near the outer side of the extended end of hydraulic cylinder assembly 34;

[0028] The discharge component 4 includes a second solenoid valve 41 installed at the bottom of the housing 31. A second three-way valve 42 for switching the liquid discharge direction at the bottom of the housing 31 is installed at the bottom of the second solenoid valve 41. A drain pipe 43 and a return pipe 44 are respectively installed on both sides of the second three-way valve 42. The first three-way valve 21, the feed pipe 22, the two sets of guide pipes 23, and the filter element 24 cooperate to achieve the switching of the mixed liquid introduction direction. This is achieved through the two sets of housings 31, the cover plate 32, the infrared sensor 33, the hydraulic cylinder assembly 34, the mounting frame 351, the bellows 352, and the anti-detachment block. 353, docking ring 361, membrane 362, first valve 37, and ultrasonic sensor 38 work together to achieve oil-liquid separation of the mixture. The spherical membrane 362 fully contacts the mixture to improve the oil-water separation rate.

A sealing gasket is fitted on the end of the mounting plate 242 near the housing 241. When the oil mixture passes through the housing 241, the filter plates 243 inside the housing 241 filter the solid impurities in the mixture. After the first three-way valve 21 switches the flow direction of the mixture, the original mounting plate 242 and filter plates 243 used for filtering impurities can be replaced by removing the first screw.

[0032] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0033] In use, the user introduces the required oil-water mixture into a set of separators 3 through the feed pipe 22, the first three-way valve 21, a set of conduits 23, and the filter element 24. The mixture first enters the upper side of the mounting frame 351 inside the housing 31 of the separator 3 and comes into contact with the membrane 362. The spherical membrane 362 fully contacts the mixture and performs oil-water separation. The water separated from the oil is introduced into the bottom of the housing 31 through the membrane 362, while the oil will remain in the mounting frame 351, the docking ring 361, and the upper end of the membrane 362. During this process, the infrared sensor 33 detects the liquid level remaining on the upper side of the membrane 362.

[0034] Once the liquid level reaches the appropriate height, the first three-way valve 21 is switched. At this time, the oil-water mixture is introduced into another set of separators 3 through another set of conduits 23 and filter elements 24. The first valve 37 in the original separator 3 is opened, and the oil is discharged to the oil recovery end through the first valve 37 and the oil drain pipe. At the same time, the ultrasonic sensor 38 at the bottom of the original separator 3 detects the water remaining at the bottom of the housing 31. When the water does not contain oil, the second solenoid valve 41 is opened. At this time, the water is discharged to the wastewater recovery end through the second solenoid valve 41, the second three-way valve 42, and the drain pipe 43. When the water contains oil, the... After the second three-way valve 42 reverses, the second solenoid valve 41 is opened. At this time, the oil-water mixture flows back to the oil-water mixture storage end through the second three-way valve 42 and the return pipe 44. After the discharge is completed, the cover plate 32 on the top of the original separator 3 is removed. The height of the mounting part 35 and the separation membrane assembly 36 is adjusted by the hydraulic cylinder assembly 34 so that the separation membrane assembly 36 is moved to the top of the housing 31. After the anti-detachment block 353 is separated from the housing 31, the anti-detachment block 353 is rotated to separate from the docking ring 361. The docking ring 361 and the membrane 362 are replaced to reset each link and realize the replacement of the membrane 362 used for separating oil and water.
