Description

Technical Field

[0001] This invention relates to the field of cottonseed oil processing equipment technology, specifically to a cottonseed oil filtration device for anti-wear agents. Background Technology

[0002] Anti-wear agents are additives used in lubricating oils and fuels. Their addition effectively improves the anti-wear properties of lubricants, extends the service life of machinery, and reduces maintenance and parts replacement costs. Anti-wear agents are particularly important under high temperature, high pressure, and heavy load conditions, effectively protecting mechanical parts from wear and damage. Among them, sulfurized olefin cottonseed oil anti-wear agents are deep red, transparent, viscous liquids that are easily soluble in petroleum lubricating oils. They possess excellent extreme pressure anti-wear, anti-oxidation, and low friction coefficient properties, making them an ideal substitute for sulfurized whale oil. Industrial anti-wear agent raw materials, such as cottonseed oil, often contain many impurities, affecting their use as anti-wear agents; therefore, they need to be filtered before use.

[0003] However, the existing method of direct filtration using a filter screen in the cottonseed oil filtration process cannot remove suspended solids, affecting the filtration effect and making it difficult to control the degree of filtration; therefore, it does not meet the current needs. In response, we propose a cottonseed oil filtration device for anti-wear agents. Summary of the Invention

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Please see Figures 1 to 4An embodiment of the present invention provides a cottonseed oil filtration device for anti-wear agents, comprising an operating tank 2 and an oil storage ring 5. The lower part of the operating tank (2) has a tapered structure that is wider at the top and narrower at the bottom. The oil storage ring (5) is fitted onto the outside of the operating tank (2). The inner side of the upper end of the operating tank 2 is provided with a downwardly recessed collection groove 10. A filter ring 9 is provided on the upper end face of the collection groove 10 near the center. Multiple filter seats 7 are fixedly installed on the side wall of the operating tank 2 at the position outside the collection groove. The bottom end of the filter seat 7 is provided with a flexible hose for filtration. The filter seat 7 is connected to the oil storage ring 5 via a flexible hose. An adjusting rod 15 is installed on the filter seat 7, and multiple filter plates 17 are installed on the lower end face of each adjusting rod 15. A positioning rod 16 is slidably connected to the inner side of the bottom end of the adjusting rod 15. Three centrifugal plates 14 are rotatably installed on the inner side of the bottom end of the operating tank 2. A rotating mounting bent rod 12 is fixedly installed on the upper end of each centrifugal plate 14. Four connecting seats 13 are installed on the side of each rotating mounting bent rod 12 near the inner wall of the operating tank 2. A filter screen pocket 18 is provided at the end of the connecting seat 13 near the inner wall of the operating tank 2. Specifically, the height of the upper end face of the filter plate 17 is higher than the upper end face of the collecting trough 10 near the center, thus preventing the oil in the collecting trough 10 from overflowing the filter plate 17.

[0024] The entire process involves two levels of centrifugation of cottonseed oil. At low speed, internal suspended solids are separated and pre-filtered through the filter bag 18, effectively ensuring the initial filtration effect of cottonseed oil and preventing oil residue from clogging the mesh on the filter ring 9 and filter plate 17. At high speed, precision filtration is performed through the filter ring 9 and filter plate 17 to improve the filtration effect. The filtration precision can be adjusted by the adjusting rod 15, facilitating the control of filtration precision and process.

[0025] A support base 1 is fixedly installed on the outer side of the bottom of the operating tank 2. A removable sealing cover 4 is installed on the upper surface of the operating tank 2. A drive shaft 8 is rotatably connected to the middle of the sealing cover 4. A drive motor 11 is installed at the bottom of the operating tank 2. The lower end of the drive shaft 8 passes through the operating tank 2 and is fixedly connected to the rotation output shaft of the drive motor 11. A drive frame 19 is fixedly connected to the outer side of the bottom of the drive shaft 8. The drive frame 9 is fixedly connected to the centrifuge plate 14 to drive the centrifuge plate 14 to rotate. A slag discharge pipe 3 is installed on the lower surface of the operating tank 2. The upper end of the slag discharge pipe 3 is connected to the bottom surface of the operating tank 2 and communicates with the inner cavity of the operating tank 2 so that the filter residue retained in the operating tank 2 can be discharged from the slag discharge pipe 3. After removing the sealing cover 4, the inner cavity of the operating tank 2 can be easily cleaned.

[0026] The rotating mounting bend 12 is connected and fixed to the drive shaft 8 via the drive frame 19. The upper end of the centrifuge plate 14 is connected and fixed to the rotating mounting bend 12 via screws. The side of the centrifuge plate 14 is in contact with the inner wall of the bottom of the operating tank 2. The drive frame 19 is connected and fixed to the drive shaft 8 via screws. The bottom end of the drive shaft 8 passes through the operating tank 2 and is connected to the output shaft of the drive motor 11 via a coupling.

[0027] By adopting the above technical solution, the drive motor 11 drives the rotating mounting rod 12 and the centrifugal plate 14 to rotate synchronously through the drive shaft 8 and the drive frame 19.

[0028] The lower end face of the oil storage ring 5 is provided with an oil outlet pipe 6 that communicates with the inner cavity of the oil storage ring 5. The oil outlet pipe 6 allows the filtered oil in the oil storage ring 5 to be discharged. Both the oil outlet pipe 6 and the slag outlet pipe 3 are connected to a solenoid valve (not shown in the figure). The solenoid valve controls the opening and closing of the valve to achieve oil discharge and slag discharge. After a certain stage of filtration, the slag outlet pipe 3 is opened to discharge slag. During filtration, the slag outlet pipe 3 is closed and the oil outlet pipe 6 is opened to discharge oil. The side of the filter seat 7 is sealed to the side wall of the operating tank 2 by a sealing gasket. The bottom end of the adjusting rod 15 extends through the upper end plate of the filter seat 7 to the upper end face of the filter plate 17. A positioning rod 16 is fixedly connected internally. The upper end of the positioning rod 16 extends through the filter plate 17 and into the center hole of the adjusting rod 15. The adjusting rod 15 is threadedly connected to the upper end of the filter seat 7. An adjusting handle is fixedly connected to the upper end of the adjusting rod 15. The adjusting handle allows for easy rotation of the adjusting rod 15 to adjust the filter plate 17. The filter seat 7 is connected to the collection groove 10. The filter plate 17 is filled with sponge. The filter ring 9 is fixedly connected to the operating tank 2 with screws. The filter ring 9 extends along the upper end of the collection groove 10 near the center towards the center of the operating tank 2.

[0029] By adopting the above technical solution, the filter plate 17 can be easily replaced and its quantity adjusted by separating the adjusting rod 15 from the positioning rod 16. The rotation of the adjusting rod 15 can also be used to press down the filter plate 17, adjust the mesh gap between the sponges in the filter plate, and adjust the filtration accuracy as needed.

[0030] The connecting seat 13 is fixedly connected to the rotating mounting bent rod 12. A retaining ring is provided on one side of the connecting seat 13, and the filter bag 18 is fixedly connected to the connecting seat 13 through the retaining ring.

[0031] By adopting the above technical solution, cottonseed oil under low-speed centrifugal conditions can be filtered through the filter bag 18.

[0032] The sealing cover 4 has an oil inlet on its upper surface, and a detachable funnel is provided at the oil inlet. A first filter screen is fixedly connected to the bottom of the funnel. The added oil is initially filtered through the first filter screen, and the detachable design allows the funnel to be removed to pour out the filtered impurities.

[0033] In summary, the oil storage ring 5 is fitted onto the outside of the operating tank 2 and fixed to it with a pin. Power is connected, and cottonseed oil is injected into the inside of the operating tank 2 through the oil inlet on the upper surface of the sealing cover 4. The drive motor 11 is started. The bottom end of the drive shaft 8 passes through the sealing cover 4 and the operating tank 2 and is connected to the drive motor 11 via a coupling. The rotating mounting rod 12 is connected and fixed to the drive shaft 8 via a drive frame 19. The drive frame 19 and the drive shaft 8 are fixed together with screws, allowing the drive motor 11 to operate smoothly. The drive shaft 8 and drive frame 19 drive the rotating mounting rod 12 and centrifugal plate 14 to rotate synchronously. The side of the centrifugal plate 14 is fitted against the inner wall of the bottom of the operating tank 2, so that the centrifugal plate 14 can rotate counterclockwise at low speed to centrifuge the cottonseed oil at low speed, thus separating the suspended matter in the cottonseed oil. The connecting seat 13 is connected to the rotating mounting rod 12 by threads. A retaining ring is provided on one side of the connecting seat 13. The connecting seat 13 is connected to the filter bag 18 by the retaining ring, so that the low-speed centrifugation of the cottonseed oil can be carried out through the filter bag 18. Cottonseed oil is centrifuged at high speed, and the resulting oil residue is filtered. The oil residue is temporarily stored inside the filter bag 18. Then, the centrifuge plate 14 is driven by the drive motor 11 to a high speed. While the cottonseed oil is centrifuged and filtered through the filter bag 18, the cottonseed oil, under the action of centrifugal force, flows upward along the side wall of the operating tank 2, past the edge near the collecting trough 10. After secondary filtration through the filter ring 9, it flows to the inside of the collecting trough 10. Multiple filter plates 17 are installed in each filter seat 7, and a soft filter is provided at the bottom of the filter seat 7. The filter seat 7 and the oil storage ring 5 are connected by a hose, allowing the cottonseed oil to be filtered three times through the filter plate 17 and injected into the oil storage ring 5 for storage through the hose. The bottom end of the adjusting rod 15 passes through the upper end of the filter seat 7, fits on the outside of the positioning rod 16, and presses down on the upper end surface of the filter plate 17. This allows the adjusting rod 15 to be separated from the positioning rod 16, facilitating the replacement and adjustment of the number of filter plates 17. The rotation of the adjusting rod 15 also facilitates the pressing down of the filter plates 17, improving the filtration accuracy.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
