Abstract
Description
Technical Field
[0001] This utility model relates to the field of decrystalline anthracene oil technology, specifically a decrystalline anthracene oil circulating ultra-clean filtration device. Background Technology
[0002] Decrystalline anthracene oil is a key product in the deep processing of coal tar. Due to its excellent chemical stability and compatibility, it is widely used in industrial applications requiring extremely high raw material purity, such as high-end dye synthesis, precision rubber additive production, and electronic-grade coating preparation. The performance stability and safety of downstream products are directly related to the purity of the decrystalline anthracene oil. In particular, the presence of tiny crystalline particles, colloidal impurities, and fine mechanically suspended matter can lead to problems such as uneven color, performance degradation, and shortened service life in downstream products. Therefore, achieving ultra-clean filtration of decrystalline anthracene oil through circulation has become a core technological requirement in industrial production.
[0003] In the industrial sector, anthracene oil filtration devices are mainly divided into single-stage filtration devices. Single-stage filtration devices have a simple structure, relying on a single filter layer to intercept impurities. Due to the limitation of filter pore size, they cannot simultaneously meet the dual requirements of intercepting large particulate impurities and removing tiny contaminants. If a large-pore filter layer is used, although the filtration rate can be guaranteed, it cannot effectively intercept micron-sized and smaller crystalline and colloidal impurities, and the filtration accuracy is far from meeting the ultra-clean requirements. If a fine filter layer is used, although the filtration accuracy can be improved, it is easily blocked by large particulate impurities, resulting in a sharp increase in filtration pressure and obstruction of oil flow. Frequent shutdowns for cleaning or replacement of the filter layer are required, which seriously affects the continuity of production and significantly increases equipment maintenance costs. Utility Model Content
[0004] The purpose of this invention is to provide a decrystalline anthracene oil circulating ultra-clean filtration device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a decrystalline anthracene oil circulating ultra-clean filtration device, comprising a filter cylinder, a rear end cover fixedly installed at one end of the filter cylinder, a protective cover fixedly installed on the inner side of the rear end cover, a drive motor fixedly installed on one side of the protective cover, an outer connecting ring fixedly installed on one side of the protective cover, a first transmission rubber ring rotatably installed inside the outer connecting ring, an outer filter cylinder fixedly installed on one side of the first transmission rubber ring, a second fixing ring installed inside the first transmission rubber ring, a second transmission rubber ring rotatably installed inside the second fixing ring, an intermediate filter cylinder fixedly installed on one side of the second transmission rubber ring, a first fixing ring installed inside the second transmission rubber ring, a third transmission rubber ring rotatably installed inside the first fixing ring, an inner filter cylinder fixedly installed on one side of the third transmission rubber ring, multiple connecting rods fixedly installed on one side of both the second and first fixing rings, transmission rubber wheels sleeved on the outer side of each connecting rod, and a rotating plate fixedly installed inside the third transmission rubber ring.
[0006] Preferably, a placement frame is fixedly installed at the bottom of the filter cartridge, and a collection frame is movably installed inside the placement frame.
[0007] Preferably, the outer side of the transmission rubber wheel on one side of the fixed ring two is in contact with the inner side of the transmission rubber ring one and the outer side of the transmission rubber ring two, and the outer side of the transmission rubber wheel on one side of the fixed ring one is in contact with the inner side of the transmission rubber ring two and the outer side of the transmission rubber ring three.
[0008] Preferably, the output end of the drive motor is fixedly connected to one side of the rotating plate, and the end of the connecting rod away from the first and second fixing rings is fixedly connected to the inner side of the rotating plate.
[0009] Preferably, a front end cover is fixedly installed on one side of the filter cartridge, and a cleaning sealing cover is sealed on one side of the front end cover by a hinge. A material guide pipe is connected to one side of the cleaning sealing cover, and a feeding hopper is connected to the end of the material guide pipe away from the cleaning sealing cover.
[0010] Preferably, the outer filter cartridge is located outside the middle filter cartridge, and the middle filter cartridge is located outside the inner filter cartridge.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the inner filter, middle filter and outer filter can realize multiple circulation filtration of decrystalline anthracene oil. Multiple circulation filtration significantly improves the filtration accuracy and purity of decrystalline anthracene oil, effectively avoids the problem of incomplete filtration by a single filter layer, greatly reduces the impurity content of the final oil, and significantly improves the quality stability. The multi-stage circulation filtration mode effectively disperses the overall filtration pressure. Compared with the design of traditional single-stage filtration device in which the filter layer undertakes all the interception tasks alone, the inner filter, middle filter and outer filter each perform their own functions, which greatly reduces the clogging risk and workload of a single filter layer.
[0012] In addition, after the drive motor starts, the output end can drive the inner filter cylinder, the middle filter cylinder, and the outer filter cylinder to rotate. The rotation of the inner filter cylinder, the middle filter cylinder, and the outer filter cylinder causes the contact position between the oil and the filter holes to change continuously, avoiding the formation of dead zones in the oil in a fixed area. This allows the filtration area of the filter layer to be fully utilized, further improving the filtration efficiency. The rotation of the inner filter cylinder, the middle filter cylinder, and the outer filter cylinder generates a slight centrifugal force, which not only promotes the flow of oil but also reduces the adhesion and accumulation of impurities on the surface of the filter holes. Even if some filter holes are blocked, the rotation of the inner filter cylinder, the middle filter cylinder, and the outer filter cylinder can allow the unblocked areas to continue to perform the filtration function, effectively reducing the impact of local blockage on the overall filtration effect and ensuring the stability and continuity of the filtration process.

Detailed Implementation
[0018] 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.
[0019] Please see Figures 1-4 This utility model provides a technical solution: a decrystalline anthracene oil circulating ultra-clean filtration device, including a filter cylinder 1, a rear end cover 10 fixedly installed at one end of the filter cylinder 1, a protective cover 9 fixedly installed inside the rear end cover 10, a drive motor 8 fixedly installed on one side of the protective cover 9, an outer connecting ring 14 fixedly installed on one side of the protective cover 9, a transmission rubber ring 16 rotatably installed inside the outer connecting ring 14, an outer filter cylinder 13 fixedly installed on one side of the transmission rubber ring 16, a fixing ring 22 installed inside the transmission rubber ring 16, a transmission rubber ring 17 rotatably installed inside the fixing ring 22, an intermediate filter cylinder 12 fixedly installed on one side of the transmission rubber ring 17, a fixing ring 21 installed inside the transmission rubber ring 17, a transmission rubber ring 3 19 rotatably installed inside the fixing ring 21, an inner filter cylinder 11 fixedly installed on one side of the transmission rubber ring 3 19, and a fixing ring 2... Multiple connecting rods 18 are fixedly installed on one side of both the 22 and the first fixed ring 21. A transmission rubber wheel 15 is sleeved on the outer side of each connecting rod 18. A rotating plate 20 is fixedly installed inside the third transmission rubber ring 19. A placement frame 2 is fixedly installed at the bottom of the filter cylinder 1. A collection frame 3 is movably installed inside the placement frame 2. The outer side of the transmission rubber wheel 15 on one side of the second fixed ring 22 contacts the inner side of the first transmission rubber ring 16 and the outer side of the second transmission rubber ring 17. The outer side of the transmission rubber wheel 15 on one side of the first fixed ring 21 contacts the inner side of the second transmission rubber ring 17 and the outer side of the third transmission rubber ring 19. The output end of the drive motor 8 is fixedly connected to one side of the rotating plate 20. The end of the connecting rod 18 away from the first fixed ring 21 and the second fixed ring 22 is fixedly connected to the inner side of the rotating plate 20. The outer filter cylinder 13 is located outside the middle filter cylinder 12, and the middle filter cylinder 12 is located outside the inner filter cylinder 11.
[0020] The working principle of the above technical solution is as follows: Decrystalline anthracene oil is introduced into the inner filter cylinder 11. After filtration by the inner filter cylinder 11, it enters the middle filter cylinder 12, then the outer filter cylinder 13, and finally the outer filter cylinder 13. Finally, it enters the collection box 3 inside the placement frame 2 for collection. The inner filter cylinder 11, middle filter cylinder 12, and outer filter cylinder 13 enable multiple cycles of filtration of the decrystalline anthracene oil, significantly improving its filtration accuracy and purity. This effectively avoids the problem of incomplete filtration by a single filter layer, significantly reducing the impurity content of the final oil and significantly improving its quality stability. The multi-stage circulating filtration mode effectively distributes the overall filtration pressure. Compared to the traditional single-stage filtration device where each filter layer undertakes the entire interception task, the inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 each perform their respective functions, greatly reducing the risk of clogging and workload of individual filter layers, and reducing damage or deformation of filter layers due to excessive pressure. This significantly extends the overall service life of the entire filtration device, while reducing the frequency and cost of equipment maintenance and improving production efficiency. To ensure continuous production, after the drive motor 8 starts, its output can drive the rotating plate 20 to rotate, thereby driving the transmission rubber ring 19 to rotate. Then, through the transmission rubber wheel 15, the transmission rubber rings 17 and 16 can rotate, thus driving the inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 to rotate. The rotating inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 can filter the decrystalline anthracene oil at different positions. The rotating inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 ensure that the oil and filter pores... The constantly changing contact position prevents the oil from forming dead zones in fixed areas, allowing the filter layer's filtration area to be fully utilized and further improving filtration efficiency. The rotational motion of the inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 generates a slight centrifugal force, which not only promotes oil flow but also reduces the adhesion and accumulation of impurities on the filter pore surface. Even if some filter pores become clogged, the rotation of the inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 allows the unclogged areas to continue to perform filtration, effectively reducing the impact of local clogging on the overall filtration effect and ensuring the stability and continuity of the filtration process.
[0021] In another implementation scheme, such as Figures 1-4 As shown, a front cover 7 is fixedly installed on one side of the filter cylinder 1. A cleaning sealing cover 4 is installed on one side of the front cover 7 by a hinge. A guide pipe 5 is connected to one side of the cleaning sealing cover 4. A feeding hopper 6 is connected to the end of the guide pipe 5 away from the cleaning sealing cover 4.
[0022] The front end cap 7 and the cleaning and sealing cap 4 can be used to seal the front end of the filter cylinder 1, the inner filter cylinder 11, the middle filter cylinder 12 and the outer filter cylinder 13 to prevent the decrystalline anthracene oil from flowing out during filtration. In addition, the feed hopper 6 and the feed pipe 5 can be used to add decrystalline anthracene oil into the inner filter cylinder 11.
[0023] Working principle: Decrystalline anthracene oil can be introduced into the inner filter cylinder 11. The front end cap 7 and the cleaning sealing cap 4 can seal the front ends of the filter cylinder 1, inner filter cylinder 11, intermediate filter cylinder 12, and outer filter cylinder 13 to prevent the decrystalline anthracene oil from flowing out during filtration. Additionally, the feed hopper 6 and guide pipe 5 can add decrystalline anthracene oil into the inner filter cylinder 11. After filtration in the inner filter cylinder 11, it enters the intermediate filter cylinder 12, then the outer filter cylinder 13, and finally the inner filter cylinder 1. Finally, it enters the collection box 3 inside the placement frame 2 for collection. Furthermore, the inner filter cartridge 11, intermediate filter cartridge 12, and outer filter cartridge 13 enable multiple-cycle filtration of the decrystalline anthracene oil. This multi-cycle filtration significantly improves the filtration accuracy and purity of the decrystalline anthracene oil, effectively avoiding the problem of incomplete filtration by a single filter layer. This results in a substantial reduction in the impurity content of the final oil product and a significant improvement in quality stability. The multi-stage circulation filtration mode effectively distributes the overall filtration pressure. Compared to the traditional single-stage filtration device where each filter layer bears the entire interception task, the inner filter cartridge 11, intermediate filter cartridge 12, and outer filter cartridge 13 each perform their respective functions, greatly reducing the risk of clogging and workload of individual filter layers. This also reduces damage or deformation of the filter layers due to excessive pressure, thus significantly improving filtration efficiency. This significantly extends the overall service life of the entire filtration device, while reducing the frequency and cost of equipment maintenance and improving production continuity. Furthermore, after the drive motor 8 starts, its output can drive the rotating plate 20 to rotate, thereby driving the transmission rubber ring 19 to rotate. Then, through the transmission rubber wheel 15, it can drive the transmission rubber rings 17 and 16 to rotate, thus driving the inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 to rotate. The rotating inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder 13 can filter the decrystalline anthracene oil at different positions. The rotating inner filter cylinder 11, the middle filter cylinder 12, and the outer filter cylinder... The inner filter cylinder 11, middle filter cylinder 12, and outer filter cylinder 13 continuously change the contact position between the oil and the filter holes, preventing the formation of dead zones in a fixed area and fully utilizing the filtration area of the filter layer, thus further improving filtration efficiency. The rotational motion of the inner filter cylinder 11, middle filter cylinder 12, and outer filter cylinder 13 generates a slight centrifugal force, which not only promotes oil flow but also reduces the adhesion and accumulation of impurities on the surface of the filter holes. Even if some filter holes become clogged, the rotation of the inner filter cylinder 11, middle filter cylinder 12, and outer filter cylinder 13 allows the unclogged areas to continue to perform filtration, effectively reducing the impact of local clogging on the overall filtration effect and ensuring the stability and continuity of the filtration process. The entire structure of this device is made of corrosion-resistant materials.
