Description

Technical Field

[0001] The invention relates to the technical field of oil-water separation, and in particular to an oil-water separation filter. Background Art

[0002] At present, filters for oil-water separation usually utilize the buoyancy of oil to make the oil-water mixture pass through a filler for filtering impurities, and then collect the oil after the impurities are filtered out from above the filler.

[0003] The application number is: CN115228142A discloses an existing technology called an oil-water separation filter, comprising: a first tube body, one end of the first tube body is sealed, and the end face of the sealed end of the first tube body is used as the sealing face; a second tube body is arranged in the first tube body, a plurality of through holes are arranged on the second tube body, and an opening of the second tube body is sealed by the sealing face, and the connection between the second tube body and the first tube body is sealed; a liquid inlet, an oil outlet and a water outlet are arranged on the sealing face, the liquid inlet is located in the second tube body, and the oil outlet and the water outlet are located outside the second tube body; the second tube body is used to accommodate a filler for absorbing oil; an extrusion mechanism comprises a pressing plate and a power assembly, the pressing plate is arranged in the second tube body, and the pressing plate is adapted to the shape of the inner wall of the second tube body; the power assembly is connected to the pressing plate, and the power assembly is used to drive the pressing plate to move axially along the second tube body.

[0004] Among them, the existing technology uses a push cylinder to push the pressure plate to squeeze the filler in the third tube body, so as to achieve the extrusion and cleaning of the grease adsorbed in the filler. The extrusion force is along the radial direction of the third tube body. When the filler is squeezed, it will form a certain deformation, and thus the extrusion in a single direction is difficult to ensure the extrusion and emptying of the grease in the filler. For the emptying of the grease adsorbed by the filler, if a method similar to twisting a towel is adopted, the degree of oil drainage will be higher than that of simple squeezing, and then the filler after oil drainage will have a higher adsorption rate for grease, and the regeneration effect will be better.

[0020] The present invention provides an oil-water separation filter. It has the following beneficial effects:

[0021] 1. In this oil-water separation filter, the output shaft of the push cylinder pushes the extrusion plate to descend in the inner tank cavity, and the ear plate on the wall of the extrusion plate slides in the limiting channel, and then the ear plate pushes the inner tank to rotate a certain angle. During the descending process, the extrusion plate not only applies radial extrusion pressure to the filler in the inner tank, but also applies circumferential torsion to the filler, so that the filler can be more fully extruded, and the grease in the filler is promoted to be discharged. After being extruded, the filler is discharged from the porous structure of the inner tank and then discharged from the outer shell through the oil drain pipe, thereby realizing the regeneration of the filler. After being fully extruded, the filler has less residual grease. For the adsorption of grease after regeneration, the oil absorption capacity is larger and the maintenance cycle is longer.

[0022] 2. This oil-water separation filter, through the inner tank rotating during the descending process of the extrusion plate, enables the extrusion plate to apply radial extrusion force and circumferential torsional force to the material, and the filler is completely drained of oil. Secondly, the stacking of the filler can be adjusted so that the filler is more orderly and densely filled in the cavity of the inner tank, avoiding disordered stacking of the filler in the inner tank, resulting in too low a filler loading amount affecting grease adsorption.

[0023] 3. This oil-water separation filter, by setting a shaft sleeve and a bushing tube, the shaft sleeve and the bushing tube cooperate with each other, and adding a sealing ring, allows the inner tank to rotate around the bushing, and can ensure the seal between the shaft sleeve and the bushing tube. During the oil discharge stage, the grease will only be discharged from the porous structure of the inner tank wall and will not be pressed out from the rotating connection position between the inner tank and the outer shell, so that the sealing of the inner tank cavity is guaranteed, and the effect of squeezing the filler to discharge the oil is guaranteed.

[0024] 4. This oil-water separation filter installs the push cylinder and the shell through a flange, which can ensure the fixing effect of the push cylinder. At the same time, the connection position between the push cylinder output shaft and the shell will not leak oil and affect the filtering and separation of the oil, so the basic filtering function is guaranteed.

[0025] 5. This oil-water separation filter extends into the inner tank cavity through a feed pipe, and the partition cavity formed by the outer wall of the inner tank and the inner wall of the outer shell is used for draining oil and water. The design of the drain pipe and the oil drain pipe extending into the partition cavity will not affect the supply of the oil-water mixture, and at the same time, will not affect the discharge of oil and water.

[0026] 6. This oil-water separation filter forms a porous structure on the circumferential surface of the inner tank through the leakage holes, ensuring that the water that has absorbed the grease can be discharged from the leakage holes. Secondly, the leakage holes can smoothly discharge the grease when squeezing the filler.

[0027] 7. In this oil-water separation filter, the inner bottom surface of the shell is fixedly provided with a plurality of identical side baffles, and the plurality of side baffles are distributed in a circular array with the inner liner as the center, and a plurality of contact plates are used to contact the outer wall of the inner liner. During the rotation of the inner liner, the side baffles can scrape and clean the residual grease on the outer wall of the inner liner, thereby inhibiting the accumulation of grease on the outer wall of the inner liner to form scaling, and secondly, can also ensure the patency of the leakage holes.

[0028] 8. This oil-water separation filter, by setting a spring and a guide groove, the elastic force of the spring can ensure the pushing effect on the contact plate, so that the contact plate can fit closely to the outer wall of the inner tank to improve the cleaning effect; secondly, even if the contact plate is worn during repeated use, the spring pushes the contact plate so that the gap caused by the wear of the contact plate is filled, the scraping and cleaning effect of the contact plate on the inner tank is more stable, and the actual service life will be longer.

[0029] 9. In this oil-water separation filter, the guide groove is a groove with a V-shaped horizontal cross-section, and the guide groove is the same length as the contact plate. When the contact plate scrapes the outer wall of the inner tank, the grease collected at the contact position between the contact plate and the inner tank can be guided by the guide groove to be discharged toward the bottom of the inner tank, thereby promoting the collection of the scraped grease.

[0040] An oil-water separation filter, such as Figure 1 and Figure 2 As shown, including:

[0041] The housing 10 forms a cavity structure for loading fillers for filtering oil, a feed pipe 11 for feeding is fixedly installed at the bottom of the housing 10, a drain pipe 12 for draining water and an oil drain pipe 13 for draining oil are also fixedly installed at the bottom of the housing 10;

[0042] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the adsorption component is arranged in the cavity of the shell 10 for loading fillers. The adsorption component includes an inner liner 20, an extrusion plate 21, a push cylinder 22, an ear plate 23 and a limiting channel 24. The inner liner 20 is movably arranged in the cavity of the shell 10, the push cylinder 22 is fixedly arranged on the top of the shell 10, the extrusion plate 21 is fixedly connected to the output shaft of the push cylinder 22, the push cylinder 22 is located in the cavity of the inner liner 20, and the inner wall of the inner liner 20 is provided with a limiting channel 24, the ear plate 23 is slidably arranged in the ear plate 23, the ear plate 23 is fixedly connected to the extrusion plate 21, and the extrusion plate 21 descends to push the ear plate 23 to move the inner liner 20 in a circle, and the inner liner The wall surface of the inner liner 20 forms a porous structure, and the filler is loaded in the cavity of the inner liner 20. In this embodiment, two shapes of the inner liner 20 and the extrusion plate 21 are shown. In one case, the inner liner 20 is a square box structure. In this case, the extrusion plate 21 is a square plate. The extrusion plate 21 can only extrude the filler in a straight up and down manner in the inner liner 20. In the case where the inner liner 20 is square, it is fixedly connected to the inner bottom surface of the shell 20; in another case, the inner liner 20 is a cylindrical structure, and the extrusion plate 21 is a circular plate. It can be clearly seen in the figure that, of course, it can also be other shapes. This scheme only shows a more common shape as an example;

[0043] In this scheme, it is intended to solve the problem in the prior art that the packing is not squeezed thoroughly enough during the oil discharge stage, resulting in a decrease in the amount of grease that the packing can absorb after the oil discharge treatment, thereby shortening the maintenance cycle and increasing the workload of later maintenance. By connecting the push cylinder 22 to the controller electrical signal, wherein the ports of the feed pipe 11, the drain pipe 12 and the oil discharge pipe 13 are fixedly installed with solenoid valves, and the solenoid valves are connected to the controller electrical signals. In the adsorption treatment stage, the oil-water mixture enters the inner tank 20 from the feed pipe 11, and after being adsorbed by the packing in the inner tank 20, the grease remains in the packing, and the water is discharged from the porous structure on the wall of the inner tank 20 and discharged from the outer shell 10 through the drain pipe 12. In the oil discharge stage, the controller controls the electrical The magnetic valve is closed, and the electromagnetic valve at the port of the oil drain pipe 13 is opened. The output shaft of the push cylinder 22 pushes the extrusion plate 21 to descend in the cavity of the inner tank 20. The ear plate 23 on the wall of the extrusion plate 21 slides in the limiting channel 24, and then the ear plate 23 pushes the inner tank 20 to rotate a certain angle. During the descending process, the extrusion plate 21 not only applies radial extrusion pressure to the filler in the inner tank 20, but also applies circumferential torsion to the filler, so that the filler can be more fully extruded, and the grease in the filler is promoted to be discharged. After extrusion, the filler is discharged from the porous structure of the inner tank 20 and then discharged from the outer shell 10 through the oil drain pipe 13, so as to realize the regeneration of the filler. After the filler is fully extruded, the residual grease is less. For the adsorption of grease after regeneration, the oil absorption amount is larger and the maintenance cycle is longer.

[0044] By rotating the inner liner 20 while the extrusion plate 21 descends, the extrusion plate 21 can apply radial extrusion pressure and circumferential torque to the material, and the filler is completely drained. Secondly, the stacking of the filler can be adjusted so that the filler is more orderly and densely filled in the cavity of the inner liner 20, avoiding disordered stacking of the filler in the inner liner 20 and causing the filler loading amount to be too low.

[0045] The filler includes a plurality of porous material bodies, each of which has redox graphene loaded on its surface. By arranging the filler as a plurality of porous material bodies having redox graphene loaded on its surface, the filler can fully absorb the oil in the oil-water mixture, thereby improving the accuracy of oil-water separation.

[0046] like Figure 6As shown, the inner liner 20 forms a cylindrical structure with an upper end open and a bottom sealed, the bottom of the inner liner 20 is rotatably connected to the inner bottom surface of the outer shell 10, the feed pipe 11 passes through the bottom of the inner liner 20 and extends into the cavity of the inner liner 20, a circular hole is opened at the bottom of the inner liner 20, a shaft sleeve is fixedly installed on the inner bottom surface of the inner liner 20, a bushing tube is fixedly installed on the inner bottom surface of the outer shell 10, a sealing tube is arranged inside the shaft sleeve, the shaft sleeve is rotatably connected to the bushing tube, the feed pipe 11 passes through the bushing tube and extends into the cavity of the inner liner 20, and the feed pipe 11 1 is interference fit with the bushing tube, the limiting channel 24 forms a spiral notch, the limiting channel 24 extends from the upper end surface of the inner liner 20 to the bottom of the inner liner 20, the limiting channel 24 is opened on the inner circumferential surface of the inner liner 20, the ear plate 23 forms a block structure that cooperates with the limiting channel 24, the horizontal cross-section of the ear plate 23 is semicircular, the ear plate 23 is integrally formed with the extrusion plate 21, the extrusion plate 21 forms a circular plate, the circumferential surface of the extrusion plate 21 is provided with a sealing ring, and the extrusion plate 21 is located in the cavity of the inner liner 20;

[0047] In the present solution, in order to realize the rotational connection between the inner liner 20 and the outer shell 10 and the sealing with the feed pipe 11, a shaft sleeve and a bushing tube are provided, and the shaft sleeve and the bushing tube cooperate with each other, and a sealing ring is added, so that the inner liner 20 can rotate around the bushing, and the sealing between the shaft sleeve and the bushing tube can be guaranteed. During the oil drainage stage, the grease will only be discharged from the porous structure of the wall of the inner liner 20 and will not be pressed out from the rotational connection position between the inner liner 20 and the outer shell 10, thereby ensuring the sealing inside the cavity of the inner liner 20, thereby ensuring the effect of squeezing and draining the oil from the filler.

[0048] like Figure 1 As shown, the cylinder body of the push cylinder 22 is fixedly installed on the top of the outer shell 10 through a sealing flange. An axial hole is opened on the top of the outer shell 10. The output shaft of the push cylinder 22 passes through the axial hole and is fixedly connected to the top of the extrusion plate 21. The push cylinder 22 is installed with the outer shell 10 through the flange, which can ensure the fixing effect of the push cylinder 22. At the same time, the connection position between the output shaft of the push cylinder 22 and the outer shell 10 will not leak oil and affect the filtration and separation of the oil, so the basic filtering function is guaranteed.

[0049] like Figure 2 As shown, both the drain pipe 12 and the oil drain pipe 13 pass through the bottom of the outer shell 10 and extend into the cavity of the outer shell 10. A partition cavity is formed between the inner liner 20 and the inner wall of the outer shell 10. The ports of the drain pipe 12 and the oil drain pipe 13 are located in the partition cavity and extend into the cavity of the inner liner 20 through the feed pipe 11. The partition cavity formed by the outer wall of the inner liner 20 and the inner wall of the outer shell 10 is used for draining oil and water. The design of the drain pipe 12 and the oil drain pipe 13 extending into the partition cavity will not affect the supply of the oil-water mixture, and at the same time, will not affect the discharge of oil and water.

[0050] like Figure 8As shown, the adsorption component also includes leakage holes 25. A plurality of leakage holes 25 are opened on the wall surface of the inner liner 20. The inner liner 20 forms a porous structure through the leakage holes 25. The circumferential surface of the inner liner 20 forms a porous structure through the leakage holes 25, thereby ensuring that the water adsorbed by the grease can be discharged from the leakage holes 25. Secondly, the leakage holes 25 can smoothly discharge the grease when the filler is squeezed. The leakage holes 25 are actually circular holes. A plurality of leakage holes 25 are opened on the inner wall of the inner liner 20. The distribution trajectory of the leakage holes 25 in the same row is spiral. Of course, the leakage holes 25 can also be square holes or holes of other shapes, and no excessive restrictions are made here.

[0051] like Figure 6 and Fig. 9 As shown, the cleaning structure is arranged in the cavity of the shell 10 and is used for scraping and cleaning the outside of the inner container 20;

[0052] The cleaning structure includes a side baffle 30 and a contact plate 31. The side baffle 30 is fixedly connected to the housing 10. The contact plate 31 is elastically connected to the side baffle 30. The contact plate 31 can contact the outer wall of the inner liner 20 to scrape and clean the outer wall of the inner liner 20.

[0053] In the present embodiment, a plurality of identical side baffles 30 are fixedly provided on the inner bottom surface of the outer shell 10. The plurality of side baffles 30 are distributed in a circular array with the inner liner 20 as the center, and a plurality of contact plates 31 are used to contact the outer wall of the inner liner 20. During the rotation of the inner liner 20, the side baffles 30 can scrape and clean the residual grease on the outer wall of the inner liner 20, thereby inhibiting the accumulation of grease on the outer wall of the inner liner 20 to form scale. Secondly, the unobstructed state of the leakage hole 25 can also be ensured. The side baffle 30 is a square plate, and the contact plate 31 is adapted to the cavity of the side baffle 30. A skirt is provided at the end of the side baffle 30, and the skirt is locked and fixed to the inner bottom surface of the outer shell 10 by screws.

[0054] like Fig. 9 As shown, the cleaning structure also includes a spring 32 and a guide groove 33. The side baffle 30 is provided with a slide groove near the side wall of the inner liner 20. The contact plate 31 is slidably arranged in the slide groove. The spring 32 is located in the slide groove and is fixedly connected to the side baffle 30. The end of the spring 32 is fixedly connected to the contact plate 31. The contact plate 31 is provided with a guide groove 33 near the side wall of the inner liner 20. The guide groove 33 can guide the grease scraped from the outer wall of the inner liner 20.

[0055] In this solution, as a supplement to the above solution, by providing the spring 32 and the guide groove 33, the elastic force of the spring 32 can ensure the squeezing effect on the contact plate 31, so that the contact plate 31 can be closely attached to the outer wall of the inner liner 20 to improve the cleaning effect. Secondly, even if the contact plate 31 is worn during repeated use, the spring 32 pushes the contact plate 31 so that the gap caused by the wear of the contact plate 31 is compensated, and the scraping and cleaning effect of the contact plate 31 on the inner liner 20 is more stable, and the actual service life will be longer.

[0056] The guide groove 33 is a groove with a V-shaped horizontal cross-section. The guide groove 33 is the same length as the contact plate 31. When the contact plate 31 scrapes the outer wall of the inner liner 20, the grease collected at the contact position between the contact plate 31 and the inner liner 20 can be guided through the guide groove 33 and discharged toward the bottom of the inner liner 20, thereby promoting the collection of the scraped grease.

[0057] The working principle of the present invention is as follows: by connecting the push cylinder 22 with the controller electrical signal, wherein the ports of the feed pipe 11, the drain pipe 12 and the oil drain pipe 13 are all fixedly installed with solenoid valves, and the solenoid valves are connected with the controller electrical signal. In the adsorption treatment stage, the oil-water mixture enters the inner tank 20 from the feed pipe 11, and after being adsorbed by the filler in the inner tank 20, the grease remains in the filler, and the water is discharged from the porous structure of the wall of the inner tank 20 through the drain pipe 12 and discharged out of the outer shell 10. In the oil discharge stage, the solenoid valves at the ports of the drain pipe 12 and the feed pipe 11 are closed by the controller, and the solenoid valve at the port of the oil drain pipe 13 is opened. The output shaft of the push cylinder 22 pushes the extrusion plate 21 to descend in the cavity of the inner liner 20, and the ear plate 23 on the wall of the extrusion plate 21 slides in the limiting channel 24, and then the ear plate 23 pushes the inner liner 20 to rotate a certain angle. During the descending process, the extrusion plate 21 not only applies radial extrusion force to the filler in the inner liner 20, but also applies circumferential torsion force to the filler, so that the filler can be more fully extruded. Through the leakage hole 25, the circumferential surface of the inner liner 20 forms a porous structure, ensuring that the water that has absorbed the grease can be discharged from the leakage hole 25. Secondly, the leakage hole 25 can smoothly discharge the grease when the filler is extruded;

[0058] The inner bottom surface of the outer shell 10 is fixedly provided with a plurality of identical side baffles 30, and the plurality of side baffles 30 are distributed in a circular array with the inner liner 20 as the center, and a plurality of contact plates 31 are used to contact the outer wall of the inner liner 20. During the rotation of the inner liner 20, the side baffles 30 can scrape and clean the residual grease on the outer wall of the inner liner 20. A spring 32 and a guide groove 33 are provided. The elastic force of the spring 32 can ensure the pushing effect of the contact plate 31, so that the contact plate 31 can fit tightly against the outer wall of the inner liner 20 to improve the cleaning effect. Secondly, even if the contact plate 31 is worn during repeated use, the spring 32 pushes the contact plate 31 so that the gap caused by the wear of the contact plate 31 is compensated, and the scraping and cleaning effect of the contact plate 31 on the inner liner 20 is more stable.
