Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a filter for removing crude benzene impurities. Background Art

[0002] In the field of chemical production, crude benzene is an important chemical raw material, and its purity is crucial to subsequent processing and use. However, crude benzene often contains various solid impurities, which not only affect the quality of crude benzene, but also cause damage to production equipment. Therefore, the development of an efficient filter for removing crude benzene impurities has become an urgent need in the industry. With the continuous advancement of science and technology, people's requirements for crude benzene filtration technology are also getting higher and higher. Not only do they require the filter to be able to effectively remove impurities, but they also require it to be easy to operate, low cost, and high efficiency. Against this background, a new type of filter for removing crude benzene impurities came into being.

[0003] In the prior art, filters used to remove crude benzene impurities usually adopt traditional filtering methods, such as screen filtration and sedimentation. The mechanical structure of these filters is relatively simple, and they are generally composed of a filter cavity, a filter mesh, etc. The technical principle is mainly to use the pore size of the filter mesh to intercept solid impurities, so that the crude benzene can be obtained after passing through the filter mesh. A relatively pure liquid is obtained. During the filtration process, the crude benzene liquid enters the filter cavity, and after being filtered by the filter mesh, the impurities are intercepted on the surface of the filter mesh, and the pure crude benzene liquid flows out of the filter.

[0004] At present, traditional crude benzene impurity filters have the problems of incomplete impurity removal and low efficiency in removing solid impurities. This is because traditional filters mainly rely on the physical interception effect of the filter mesh. It is difficult to effectively separate some solid impurities that are closely combined with crude benzene. Moreover, during the filtration process, impurities can easily clog the filter mesh, reducing the filtration efficiency. As the crude benzene continues to flow, impurities accumulate on the surface of the filter mesh, which will further affect the filtration effect. This incomplete impurity removal method will not only affect the quality of the crude benzene, but may also cause damage to the equipment in the subsequent processing process, increasing production costs. Therefore, a filter for removing crude benzene impurities is proposed to solve the above problems. Utility Model Content

[0024] 1. In the utility model, the driving motor on the side wall of the bracket is started, driving the disc to rotate, thereby causing the ball arm to rotate in the ball seat, the connecting arm to shake, and the filter barrel to shake accordingly.

[0025] 2. In this utility model, when the recycling tank needs to be replaced, the worker manually slides the movable ring downward.

This achieves the effect of quickly unlocking the tank, allowing workers to quickly replace and clean the tank, solving the problem of inconvenient replacement affecting work efficiency, and improving the maintainability and overall work efficiency of the equipment.

The filter barrel 3 is the core component of the filter and is made of high-strength carbon steel. Carbon steel has good strength and corrosion resistance and can withstand the pressure of the internal liquid and the external force. The inner wall of the barrel has been specially treated and has a certain roughness, which can increase the friction between the solid impurities and the inner wall of the filter barrel 3, making it easier to be intercepted. The side wall of the filter barrel 3 is fixedly connected with a plurality of fixing rings 10. The fixing ring 10 is connected to the filter barrel 3 by welding, which can ensure that it will not loosen or fall off during the shaking of the filter barrel 3. The left and right sides of the fixing ring 10 are fixedly connected with connecting arms 11. A ball seat 12 is provided inside the connecting arm 11. The ball arm 17 is slidably connected to the inner wall of the ball seat 12. The ball arm 17 is made of stainless steel. The surface is smooth and has a certain strength. At the same time, the inner wall of the ball seat 12 has been smoothed and fits tightly with the ball arm 17, ensuring that the ball arm 17 rotates smoothly therein. The side wall of the connecting arm 11 is fixedly connected to the fixed arm 18, and one end of the fixed arm 18 is rotatably connected to the runner 19. The side wall of the bracket 2 is fixedly connected to the hollow disk 20, and the runner 19 is slidably connected to the inner wall of the hollow disk 20. The inner wall of the hollow disk 20 has been smoothed and fits tightly with the runner 19, ensuring that the runner 19 rotates smoothly therein. The top of the filter barrel 3 is fixedly connected with the feed valve 4, the liquid inlet valve 5, and the steam valve 6. The above valves are made of stainless steel with good corrosion resistance and sealing. The internal structure of the valve has been precisely processed and can be accurately controlled by the controller. To control the flow rate and flow rate of the crude benzene liquid, a discharge valve 7 and a liquid discharge valve 8 are fixedly connected to the bottom of the filter barrel 3. The structure and material of the discharge valve 7 are similar to those of the feed valve 4, which can ensure that the filtered crude benzene liquid flows out smoothly while preventing external impurities from entering the filter barrel 3. The bottom of the liquid discharge valve 8 is slidably connected to an organic tank 9. The organic tank 9 is made of plastic or stainless steel and has good corrosion resistance and sealing. The surface of the organic tank 9 is also provided with some markings and scales to facilitate the staff to understand the capacity and properties of the liquid in the tank. The organic tank 9 is made of stainless steel, has good corrosion resistance and sealing, and can store recycled organic matter. A connecting component is provided between the liquid discharge valve 8 and the organic tank 9, and the connecting component is used to connect the liquid discharge valve 8 and the organic tank 9.The support assembly includes a support plate 14. The top of the support plate 14 is fixedly connected to the bottom of the drive motor 13 by bolts, which can provide stable support for the drive motor 13. The top of the support plate 14 is fixedly connected to the bottom of the drive motor 13. The bottom of the support plate 14 is fixedly connected to a support arm 15. The side wall of the support arm 15 is fixedly connected to the side wall of the bracket 2. Through the function of the support assembly, the stability of the drive motor 13 during operation can be ensured, thereby improving the reliability and service life of the equipment.

[0034] Specifically, when using the device, the crude benzene is first filtered. The crude benzene liquid enters the filter barrel 3 through the feed valve 4 for filtration. The side wall of the filter barrel 3 is fixedly connected with a plurality of fixing rings 10. The filtered crude benzene liquid flows to the next link through the discharge valve 7. Subsequently, the steam valve 6 injects steam into the filter barrel 3. After the oil phase is separated, the liquid inlet valve 5 injects water into the filter barrel 3 to flush the solid impurities inside. The injected water can flush the solid impurities and make it easier to discharge them through the liquid outlet valve 8. The flushed liquid enters the organic tank 9 through the liquid outlet valve 8 for filtration. Organic matter is recovered. At this time, the drive motor 13 on the side wall of the bracket 2 starts to work, and the drive motor 13 drives the disc 16 to start rotating. The rotation of the disc 16 drives the ball arm 17 to rotate accordingly. The rotation of the ball arm 17 inside the ball seat 12 drives the connecting arm 11 to shake. The shaking movement of the connecting arm 11 drives the entire filter barrel 3 to shake accordingly. At the same time, the fixed arm 18 on the side wall of the connecting arm 11 also moves accordingly, driving the runner 19 to rotate on the inner wall of the hollow disc 20, thereby achieving the effect of efficiently and quickly shaking the filter barrel 3, so that solid impurities are separated more quickly, and the filtration efficiency and quality are improved.

[0035] Reference Figure 3 - Figure 4, the connecting component includes a base 21, which is fixedly connected to the bottom of the inner wall of the liquid outlet valve 8. The base 21, as the part connected to the liquid outlet valve 8, is made of high-strength plastic material, has good corrosion resistance and sealing, and can ensure that the liquid will not leak from the connection part. The top of the inner wall of the organic tank 9 is fixedly connected with a base 22. The material of the base 22 is similar to that of the base 21, and also has good corrosion resistance and sealing. The inner walls of the base 1 21 and the base 2 22 are fixedly connected with a fixing plate 28. The fixing plate 28 is made of stainless steel and has high strength and stability. The side wall of the fixing plate 28 is fixedly connected with a connecting column 27. The top of the connecting column 27 is fixedly connected to a conical block 26. The conical block 26 is made of rubber material and has good elasticity and sealing. Its conical design can provide better when closing the pipeline. Sealing effect, the outer wall of the connecting column 27 is provided with a spring 29, one end of the spring 29 is fixedly connected to the side wall of the fixed plate 28, and the other end of the spring 29 is fixedly connected to the side wall of the tapered block 26. When the pipeline is in the open state, the spring 29 is in a compressed state to store elastic potential energy. The inner wall of the base 22 is slidably connected with a plurality of balls 24. The balls 24 are distributed in a circular ring shape and have enough space to roll when squeezed, thereby realizing the locking and unlocking function of the connection between the base 1 21 and the base 2 22. The outer wall of the base 22 is slidably connected with a movable ring 23. The movable ring 23 is made of plastic material and the surface is anti-slip treated to facilitate the staff to hold and apply force. The outer wall of the base 22 is provided with a spring 25. The function of the spring 25 is to provide a certain restoring force after the movable ring 23 slides, so that the movable ring 23 can automatically return to the initial position;

[0036] Specifically, when the organic tank 9 needs to be replaced and recycled, the staff first manually slides the movable ring 23 downward. Under the external force of the staff, the movable ring 23 slides downward along the outer wall of the base 22. The sliding direction of the movable ring 23 is consistent with the axial direction of the base 22, ensuring the stability of the sliding process. As the movable ring 23 moves, the ball 24 inside the base 22 loses the lateral extrusion force and becomes loose. When the movable ring 23 slides downward, its inner wall gradually moves away from the ball 24, so that the ball 24 is no longer squeezed by the movable ring 23. Because the balls 24 lose their lateral compressive force, they become loose in the space inside base 2 2 and no longer tightly grip base 1 21. At this time, spring 29 on the inner walls of bases 1 21 and 2 22 recovers and rebounds, pushing conical block 26 to move. When the balls 24 lose their compressive force, spring 29 releases its stored elastic potential energy and begins to rebound. The rebound force of spring 29 pushes conical block 26 toward the center of the pipeline. Driven by spring 29, conical block 26 gradually approaches and eventually blocks the pipelines between bases 1 21 and 2 22, preventing further outflow of liquid. This blocks the pipelines between bases 1 21 and 2 22. Once conical block 26 has blocked the pipelines, the operator can safely remove the organic tank 9, thereby quickly unlocking the organic tank 9 and allowing the operator to quickly replace and clean the organic tank 9, improving the efficiency and convenience of the equipment.

[0037] Working principle: When using the device, first, the crude benzene liquid enters the filter barrel 3 through the feed valve 4 for filtration, and the filtered crude benzene liquid flows to the next link through the discharge valve 7, and then the steam valve 6 injects steam into the filter barrel 3 to separate the solid impurities from the oil phase. After separation from the oil phase, the liquid inlet valve 5 injects water into the filter barrel 3 to flush the solid impurities inside, and enters the organic tank 9 through the liquid outlet valve 8 for organic matter recovery. At this time, the drive motor 13 on the side wall of the bracket 2 starts to work, driving the disc 16 to start rotating. The rotation of the disc 16 drives the ball arm 17 to rotate accordingly. The rotation of the ball arm 17 inside the ball seat 12 drives the connecting arm 11 to shake, and the connecting arm 11 drives the entire filter barrel 3 to shake. At the same time, the connecting arm 1 The fixed arm 18 on the side wall of 1 also moves accordingly. The displacement of the fixed arm 18 drives the runner 19 to rotate on the inner wall of the hollow disk 20, thereby achieving the effect of shaking the filter barrel 3 efficiently and quickly, so that the solid impurities are separated more quickly. When the organic tank 9 needs to be replaced and recycled, the staff first manually slides the movable ring 23 downward. As the movable ring 23 moves, the ball 24 inside the base 22 loses the lateral extrusion force and becomes loose. At this time, the spring 29 on the inner wall of the base 1 21 and the base 2 22 recovers and rebounds to push the conical block 26 to move, thereby blocking the pipelines of the base 1 21 and the base 2 22, and the organic tank 9 can be removed, thereby achieving the effect of quickly unlocking the organic tank 9, so that the staff can quickly replace and clean the organic tank 9.
