Description

Technical Field

[0001] This utility model relates to the field of decrystalline anthracene oil filtration technology, specifically a multi-layer filtration device for decrystalline anthracene oil with good filtration effect. Background Technology

[0002] Decrystalline anthracene oil, an important byproduct of coal tar processing, is widely used in various industrial fields such as dyes, coatings, and rubber additives. Its purity directly affects the quality and performance of downstream products. Therefore, filtration and purification are crucial steps in the production and processing of decrystalline anthracene oil. The core objective is to remove residual crystalline particles, mechanical impurities, and fine suspended solids from the oil to ensure that the product meets industrial standards.

[0003] Industrially used decrystalline anthracene oil filtration devices mostly employ single-stage filtration or simple multi-stage filtration structures. While single-stage filtration devices, which filter the oil using only a single layer of filter media, are simple in structure and easy to operate, they have significant drawbacks. Because the size range of impurities in decrystalline anthracene oil is quite wide, ranging from micron-sized fine crystals to millimeter-sized mechanical impurities, the pore size of a single-stage filter layer is insufficient to simultaneously trap both coarse and fine impurities. If a large-pore filter layer is used, it cannot effectively remove tiny impurities, resulting in insufficient filtration precision. Conversely, if a fine filter layer is used, it is easily clogged by large particles, leading to a sudden increase in filtration pressure and a sharp decrease in filtration efficiency, requiring frequent shutdowns for filter layer cleaning, severely impacting production continuity. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer filter device for decrystalline anthracene oil with good filtration effect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer filter device for decrystalline anthracene oil with good filtration effect, comprising a filter box, a rotating rod rotatably installed inside the filter box, sleeves sleeved on the outer sides of the rotating rod, two connecting frames symmetrically fixedly installed on the outer sides of the sleeves, connecting seats fixedly installed at the ends of the two connecting frames away from the sleeves, scrapers and brushes fixedly installed on the sides of the two connecting seats away from the connecting frames, a drive assembly installed on the back of the filter box, three sealing arc-shaped brackets fixedly installed inside the filter box, three sealing insertion slots opened on one side of the filter box, filter frames installed inside the three sealing insertion slots, and a discharge chute opened at the bottom of one side of the filter box.

[0006] Preferably, one end of each of the three filter frames is sealed and snapped into the interior of the sealing arc-shaped bracket, and a handle is fixedly installed on the end of each filter frame away from the sealing arc-shaped bracket.

[0007] Preferably, three arc-shaped protective plates are fixedly installed on both sides of the inner cavity of the filter box. The bottom of the arc-shaped protective plates is in contact with the top of both ends of the filter frame. Sealing rubber is installed on the bottom of the arc-shaped protective plates and the top of both ends of the filter frame.

[0008] Preferably, an inclined guide plate is fixedly installed at the bottom of the inner cavity of the filter box, and a material guide frame is fixedly installed on one side of the filter box, with the position of the material guide frame corresponding to the position of the discharge chute.

[0009] Preferably, the drive assembly includes a third drive wheel, a second drive wheel, and two first drive wheels. One side of the third drive wheel and the two first drive wheels are respectively fixedly connected to one end of three rotating rods. The second drive wheel is fixedly connected to the side of one of the first drive wheels away from the rotating rod. A drive belt is sleeved between the two first drive wheels and between the second drive wheel and the third drive wheel. A protective cover is fixedly installed on one side of the filter box. A drive motor is fixedly installed at the end of the protective cover away from the filter box. The output end of the drive motor is fixedly connected to one side of one of the first drive wheels.

[0010] Preferably, the bottom of the filter box is symmetrically and fixedly installed with four support legs, and the top of the filter box is fixedly installed with a feeding hopper.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the three filter frames can form a multi-level gradient filtration structure, which can achieve step-by-step interception of impurities in decrystalline anthracene oil. Multiple filtrations not only improve the filtration effect of decrystalline anthracene oil, but also reduce the filtration pressure on a single filter frame, extending the service life of the device. The multi-level gradient filtration design can significantly improve the filtration accuracy and purity of decrystalline anthracene oil, making the final oil quality more stable, and can also effectively disperse the filtration pressure, preventing impurities from being intercepted by a single filter layer, which can easily cause filter pore blockage and sudden increase in filtration pressure, affecting filtration efficiency and device lifespan. This multi-level filtration structure, through the reasonable division of labor among the three filter layers, intercepts impurities of different sizes in the corresponding filter layers, making the filtration load borne by each filter frame more uniform, greatly reducing the risk of blockage and working pressure of a single filter layer, thereby extending the overall service life and maintenance cycle of the entire filtration device.

[0012] In addition, after the drive motor starts, the three rotating rods can be rotated through the cooperation of the two transmission wheels and the transmission belt, thereby driving the sleeve to rotate, driving the connecting frame and the connecting seat to rotate, and thus the scraper and brush plate to rotate. This scrapes and brushes the inside of the three filter frames to prevent crystallization and impurities from clogging the filter holes. It can also accelerate the flowability of the decrystalline anthracene oil, further improving the filtration effect and filtration rate, and ensuring that the entire filtration process can be carried out continuously and efficiently.

[0019] 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.

[0020] Please see Figures 1-5This utility model provides a technical solution: a multi-layer filter device for decrystalline anthracene oil with good filtration effect, including a filter box 1. A rotating rod 20 is rotatably installed inside the filter box 1. Sleeves 15 are sleeved on the outer sides of the rotating rod 20. Two connecting frames 16 are symmetrically fixed on the outer sides of the sleeves 15. Connecting seats 17 are fixedly installed at the ends of the two connecting frames 16 away from the sleeves 15. Scrapers 18 and brushes 19 are fixedly installed on the sides of the two connecting seats 17 away from the connecting frames 16, respectively. A drive assembly is installed on the back of the filter box 1. Three sealing arc-shaped retainers 14 are fixedly installed inside the filter box 1. Three sealing insertion slots 23 are opened on one side of the filter box 1. Filter frames 3 are sealed and snap-fitted into the interior of each of the three sealing insertion slots 23. A discharge trough is opened at the bottom of one side of the filter box 1. 6. One end of each of the three filter frames 3 is sealed and snapped into the inside of the sealed arc-shaped bracket 14. A handle 4 is fixedly installed on the end of each filter frame 3 away from the sealed arc-shaped bracket 14. The drive assembly includes a transmission wheel 3 13, a transmission wheel 2 12, and two transmission wheels 10. One side of the transmission wheel 3 13 and the two transmission wheels 10 are respectively fixedly connected to one end of the three rotating rods 20. The transmission wheel 2 12 is fixedly connected to the side of one of the transmission wheels 10 away from the rotating rod 20. A transmission belt 11 is sleeved between the two transmission wheels 10 and between the transmission wheel 2 12 and the transmission wheel 3 13. A protective cover 9 is fixedly installed on one side of the filter box 1. A drive motor 8 is fixedly installed on the end of the protective cover 9 away from the filter box 1. The output end of the drive motor 8 is fixedly connected to one side of one of the transmission wheels 10.

[0021] The working principle of the above technical solution is as follows: Decrystalline anthracene oil can be poured into the filter box 1. Under the influence of its own weight and fluidity, the decrystalline anthracene oil will pass through three filter frames 3 in sequence. The size of the filter pores inside the three filter frames 3 decreases from top to bottom, with the upper filter frame 3 having the largest pore diameter, the middle filter frame 3 having a medium pore size, and the lower filter frame 3 having the finest pores. This multi-stage gradient filtration structure can achieve a step-by-step interception of impurities in the decrystalline anthracene oil. First, the larger crystalline particles in the oil are quickly intercepted by the upper large-pore filter frame 3. Mechanical impurities and other coarse contaminants are filtered out to prevent large particles from directly entering the subsequent fine filter layer and causing blockage. The middle filter frame 3 further filters out medium-sized suspended impurities. Finally, the lower fine filter layer deeply traps tiny crystals and fine impurities, thus filtering the crystals and impurities within the decrystalline anthracene oil. Multiple filtrations not only improve the filtration effect on the decrystalline anthracene oil but also reduce the filtration pressure on individual filter frames 3, extending the lifespan of the device. This multi-gradient filtration design significantly improves the filtration accuracy and purity of the decrystalline anthracene oil, allowing... The final product has a more stable oil quality and can effectively distribute filtration pressure. This prevents impurities from being trapped by a single filter layer, which can easily cause rapid clogging of the filter pores and a sudden increase in filtration pressure, affecting filtration efficiency and the service life of the device. However, this multi-stage filtration structure, through the reasonable division of labor among the three filter layers, intercepts impurities of different sizes in their respective filter layers, making the filtration load on each filter frame 3 more uniform. This significantly reduces the risk of clogging and working pressure of a single filter layer, thereby extending the overall service life and maintenance cycle of the entire filtration device. In addition, after the drive motor 8 starts, the three rotating rods 20 can be rotated through the cooperation of the two transmission wheels 10, transmission wheels 12, transmission wheels 13 and transmission belt 11, thereby driving the sleeve 15 to rotate, driving the connecting frame 16 and connecting seat 17 to rotate, thereby causing the scraper 18 and brush 19 to rotate, thus scraping and brushing the inner side of the three filter frames 3, preventing crystallization and impurities from clogging the filter pores, and also accelerating the flowability of the decrystalline anthracene oil, further improving the filtration effect and filtration rate, ensuring that the entire filtration process can be carried out continuously and efficiently.

[0022] In another implementation scheme, such as Figures 1-5 As shown, three arc-shaped protective plates 22 are fixedly installed on both sides of the inner cavity of the filter box 1. The bottom of the arc-shaped protective plate 22 contacts the top of both ends of the filter frame 3. Sealing rubber is installed on the bottom of the arc-shaped protective plate 22 and the top of both ends of the filter frame 3.

[0023] The arc-shaped baffle 22 prevents the decrystalline anthracene oil inside the filter frame 3 from splashing into the filter box 1, ensuring that the decrystalline anthracene oil must pass through the three filter frames 3 before entering the bottom of the filter box 1 and then being discharged through the discharge chute 6.

[0024] In another implementation scheme, such as Figures 1-5 As shown, an inclined guide plate 21 is fixedly installed at the bottom of the inner cavity of the filter box 1, a guide frame 7 is fixedly installed on one side of the filter box 1, and the position of the guide frame 7 corresponds to the position of the discharge chute 6. Four support legs 5 are symmetrically fixedly installed at the bottom of the filter box 1, and a feeding hopper 2 is fixedly installed at the top of the filter box 1.

[0025] The inclined guide plate 21 facilitates the guidance of the decrystalline anthracene oil after filtration through the three filter frames 3 to the discharge trough 6, and then discharges it through the discharge trough 6. The decrystalline anthracene oil discharged through the discharge trough 6 can be easily collected by the inclined guide plate 21. In addition, the support leg 5 can support the whole device, and the feeding hopper 2 can easily pour the decrystalline anthracene oil into the filter box 1.

[0026] Working principle: The decrystalline anthracene oil can be poured into the filter box 1. Under the influence of its own weight and fluidity, the decrystalline anthracene oil will pass through three filter frames 3 in sequence. The size of the filter pores in the three filter frames 3 decreases from top to bottom. The filter pores in the upper filter frame 3 have the largest diameter, the filter pores in the middle filter frame 3 have a medium size, and the filter pores in the lower filter frame 3 have the finest. This multi-stage gradient filtration structure can achieve a step-by-step interception of impurities in the decrystalline anthracene oil. First, the upper filter frame 3 with its large pore size quickly intercepts large crystal particles, mechanical impurities, and other coarse contaminants in the oil, preventing large particles from directly entering the subsequent fine filter layer and causing blockage. Then, the middle filter frame 3 further filters out medium-sized suspended impurities. Finally, the lower fine filter layer... The dense filter pores effectively trap tiny crystals and fine impurities, thus filtering the crystals and impurities within the decrystalline anthracene oil. Multiple filtrations not only improve the filtration efficiency of the decrystalline anthracene oil but also reduce the filtration pressure on individual filter frames, extending the lifespan of the device. The multi-stage gradient filtration design significantly improves the filtration precision and purity of the decrystalline anthracene oil, resulting in a more stable final oil quality. It also effectively disperses filtration pressure, preventing impurities from being trapped by a single filter layer, which can quickly cause filter pore blockage, sudden increases in filtration pressure, and reduced filtration efficiency and device lifespan. This multi-stage filtration structure, through the rational division of labor among the three filter layers, intercepts impurities of different sizes in their respective layers, ensuring that each layer effectively traps impurities. The filter load borne by each filter frame 3 is more even, significantly reducing the risk of clogging and working pressure on individual filter layers, thereby extending the overall service life and maintenance cycle of the entire filter device. Furthermore, after the drive motor 8 starts, the three rotating rods 20 can rotate through the cooperation of two transmission wheels 10, transmission wheels 12, transmission wheels 13, and the transmission belt 11. This rotation drives the sleeve 15 to rotate, which in turn drives the connecting frame 16 and the connecting seat 17 to rotate, thereby causing the scraper 18 and the brush 19 to rotate. This scrapes and brushes the inner sides of the three filter frames 3, preventing crystallization and impurities from clogging the filter holes. It also accelerates the flowability of the decrystalline anthracene oil, further improving the filtration effect and filtration rate, ensuring the entire process is efficient. The filtration process can be carried out continuously and efficiently. The arc-shaped baffle 22 can prevent the decrystalline anthracene oil inside the filter frame 3 from splashing into the filter box 1, ensuring that the decrystalline anthracene oil must be filtered through three filter frames 3 before entering the bottom of the inner cavity of the filter box 1, and then discharged through the discharge chute 6. The inclined guide plate 21 facilitates the guidance of the decrystalline anthracene oil after filtration through the three filter frames 3 to the discharge chute 6, and then discharges it through the discharge chute 6. The decrystalline anthracene oil discharged through the discharge chute 6 can be easily collected through the inclined guide plate 21. In addition, the supporting legs 5 can support the entire device, and the feeding hopper 2 facilitates the pouring of the decrystalline anthracene oil into the interior of the filter box 1. The entire structure of this device is made of corrosion-resistant materials.
