Description

Technical Field

[0001] This utility model relates to the field of general physical or chemical methods or apparatus, and in particular to a vertical filtration device for chemical production. Background Technology

[0002] With the advancement of technology, most vertical centrifugal filtration devices now possess good filtration effects, effectively separating filter residue from filtrate. Chinese utility model patent, authorization announcement number "CN207324249U," discloses a vertical filtration device for chemical production, including a tank body. Inside the tank body is a filter tank. A sealing door is located on the left side of the tank body. An inner arc-shaped frame is located on the inner side of the sealing plate. A scraper is located on the right side of the top of the jacket. Rubber teeth are provided on the outer wall of the first sleeve, and a brush is provided on the outer wall of the second sleeve. A sponge sleeve is fitted onto the outer side of the first rotating roller. This vertical filtration device for chemical production, through the cooperation of the scraper, rubber teeth, brush, and sponge sleeve, initially cleans the large amount of impurities adhering to the outer wall of the filter tank by contact with the scraper when the filter tank rotates. The elastic force of the compression spring pushes the vertical roller, second rotating roller, third rotating roller, and first rotating roller inside the inner arc-shaped frame to tightly adhere to the filter tank.

[0003] The above technical solution uses a combination of scrapers, rubber teeth, brushes, and sponge sleeves to initially clean the large amount of impurities adhering to the outer wall of the filter tank by contact with the scrapers when the filter tank rotates. The rubber teeth on the outer wall of the first sleeve insert into the mesh holes inside the filter tank to unclog the mesh holes. However, the above technical solution still has certain drawbacks. For example, although the above equipment uses the contact of scrapers to initially clean the outer wall of the filter tank, when the filter element needs maintenance and repair after long-term use, workers need to use special tools to open the filter tank and disassemble the filter element. This increases the workload of workers and reduces the efficiency of filter element maintenance and repair. Utility Model Content

[0030] Please see Figure 1-4 This utility model provides a technical solution: a vertical filtration device for chemical production, including a vertical filter tank 1;

[0031] A limit device is installed on the vertical filter tank 1;

[0032] The limiting device includes a movable plate 6, four fixed brackets 3, and four mounting seats 19. The upper outer wall of the movable plate 6 is slidably connected to the inner wall of the lower opening of the vertical filter tank 1. The four mounting seats 19 are all fixedly connected to the lower outer wall of the vertical filter tank 1. A sealing ring 17 is installed on the upper surface of the movable plate 6, and the outer wall of the sealing ring 17 contacts the lower inner wall of the vertical filter tank 1. Two fixed plates 5 are fixedly connected to the outer walls of each of the four mounting seats 19. The eight fixed plates 5 are arranged in pairs. The four fixed brackets 3 are all L-shaped. A filter element 11 is rotatably connected to the outer wall of the movable plate 6 near the vertical filter tank 1. Rotating columns 4 are fixedly connected to the upper outer walls of each of the four fixed brackets 3. Rotating column grooves 18 are opened on the outer walls of the four sets of fixed plates 5. Both outer walls are slidably connected to the interior of the corresponding rotating column groove 18. The outer wall of the movable plate 6 away from the vertical filter tank 1 is fixedly connected to a motor 14. The output end of the motor 14 extends to the outside of one side of the movable plate 6 and is fixedly connected to the lower surface of the filter element 11. The lower outer walls of the four fixed brackets 3 are threaded with fixing bolts 16. The lower outer wall of the movable plate 6 is provided with a fixing bracket groove 12. The lower outer walls of the four fixed brackets 3 are respectively in contact with the inner wall of the corresponding fixing bracket groove 12. The interior of the four fixing bracket grooves 12 is provided with fixing bolt grooves 13. The end of the four fixing bolts 16 near the fixing bracket groove 12 is threaded into the interior of the fixing bracket groove 12 and is respectively threadedly connected to the interior of the corresponding fixing bolt groove 13.

[0033] The vertical filter tank 1 has a support base 2 installed on its lower outer wall. The four support legs on the lower surface of the support base 2 are in contact with the ground. The end of the vertical filter tank 1 near the support base 2 extends to the lower outside of the support base 2. The upper surface of the vertical filter tank 1 is fixedly connected to a feed pipe 8, which communicates with the interior of the vertical filter tank 1. The inner wall of the cleaning rack at the lower end of the vertical filter tank 1 is fixedly connected to four cleaning scrapers 10, whose outer walls are in contact with the outer wall of the filter element 11. The upper surface of the support base 2 is equipped with a water pump 9. The inner wall of the cleaning rack at the lower end of the vertical filter tank 1 is equipped with multiple spray heads 15. The input end of the water pump 9 is connected to the multiple spray heads 15 through the cleaning rack at the lower end of the vertical filter tank 1. The lower outer wall of the vertical filter tank 1 is fixedly connected to a discharge pipe 7, which communicates with the interior of the vertical filter tank 1.

[0034] Furthermore, when using this device, it is started by connecting to an external power source. First, the external equipment is connected to the feed pipe 8. Then, the external equipment feeds raw material into the vertical filter tank 1 through the feed pipe 8, causing the raw material to fall into the filter element 11. Then, the output end of the motor 14 rotates, driving the filter element 11 to rotate, while the material passes through the filter holes on the vertical filter tank 1 and enters the filtrate collection pipe. The solid particles are trapped on the surface of the vertical filter tank 1 to form a filter cake. At the same time, when the filter element 11 rotates, the cleaning scraper 10 on the inner wall of the cleaning rack at the lower end of the vertical filter tank 1 cleans the surface of the filter element 11. At the same time, the output end of the water pump 9 connects to the filter element 11. The filter element 11 is sprayed onto the filter element 11 by the spray nozzle 15 inside the cleaning frame at the lower end of the vertical filter tank 1, which is connected to the external water storage tank via a connecting pipe. Then, when the filter element 11 needs to be removed, the fixing bolt 16 is turned to rotate so that the outer wall of the other end is disengaged from the inside of the fixing bolt groove 13. Then, the fixing frame 3 is flipped so that it is rotated around the rotating column 4, so that the outer wall of one end is disengaged from the inside of the fixing frame groove 12. After the movable plate 6 loses its limit, the movable plate 6 can be removed from the vertical filter tank 1, and the filter element 11 can be removed from the inside of the vertical filter tank 1 at the same time.

[0035] By rotating the fixing bolt 16 in the limiting device, the outer wall of its other end is disengaged from the inside of the fixing bolt groove 13. Then, the fixing frame 3 is flipped around the rotating column 4, thus disengaging one end of its outer wall from the inside of the fixing frame groove 12. This removes the limiting position of the movable plate 6, allowing it to be removed from the vertical filter tank 1 simultaneously, and the filter element 11 to be removed from its interior. This method of disassembling the filter element 11 is simple and quick, avoiding the need for workers to use special tools to open the vertical filter tank 1 before disassembling the filter element 11. This reduces the workload of staff. As the filter element 11 rotates, the surface of the filter element 11 is cleaned by the cleaning scraper 10 on the inner wall of the cleaning frame at the lower end of the vertical filter tank 1. At the same time, the output end of the water pump 9 is connected to the external water storage tank through the connecting pipe. The water pump 9 draws water and delivers it to the spray head 15 inside the cleaning frame at the lower end of the vertical filter tank 1. The spray head 15 sprays water onto the filter element 11, thus cleaning the outer wall of the filter element 11. This effectively prevents the filter pores of the filter element 11 from becoming clogged, while increasing the cleaning effect and thus improving the work efficiency of the staff.
