Description

Technical Field

[0001] This utility model relates to the field of aramid fiber processing technology, specifically to an aramid fiber slurry filtration device. Background Technology

[0002] Aramid fiber slurry filtration device is a specialized equipment for processing and filtering aramid fiber slurry. Chinese Patent Publication No. CN211885643U discloses an aramid fiber slurry filtration device, including a base with a support platform fixedly mounted on its top. This aramid fiber slurry filtration device, through a feed pipe, allows the aramid fiber slurry to be fed into the interior of a separation screen. Then, a motor is started, causing the agitator to rotate, thus rotating the aramid fiber slurry. During rotation, the aramid fiber slurry is thrown outwards by centrifugal force, allowing it to enter the filtration chamber and be discharged through a discharge pipe. This process can be repeated multiple times. When there are many impurities or other substances inside the separation screen, the chamber lid can be lifted, and the separation screen removed for cleaning. This structure facilitates cleaning, increases filtration efficiency, and reduces manual labor.

[0003] The above patent filters aramid fiber slurry using a separation mesh. This patent sets the separation mesh in a barrel shape to separate impurities and solid particles in the aramid fiber slurry. However, when cleaning the inside of the barrel-shaped separation mesh, due to its height and depth, it is inconvenient for personnel to clean the inner wall and bottom. To reach the bottom of the inner part of the barrel-shaped separation mesh, personnel need to use a cleaning brush that is compatible with the depth of the barrel-shaped separation mesh, thus causing inconvenience and affecting work efficiency.

[0004] Therefore, an aramid fiber slurry filtration device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an aramid fiber slurry filtration device in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A filter device for aramid fiber slurry includes a filter tank and a top cover. The surfaces of the filter tank and the top cover are provided with an electric push rod for driving the top cover longitudinally.

[0024] like Figures 1 to 4 As shown, an aramid fiber slurry filtration device includes a filter tank 1 and a top cover 2. The surfaces of the filter tank 1 and the top cover 2 are provided with an electric push rod 3 for driving the top cover 2 longitudinally. The telescopic end of the electric push rod 3 is bolted to the surface of the top cover 2. A feed pipe 4 is fixedly provided on the surface of the top cover 2, and the bottom end of the feed pipe 4 extends to the bottom of the top cover 2. A discharge pipe 5 is fixedly provided at the bottom of the filter tank 1, and a control valve 6 is provided on the surface of the discharge pipe 5. A filter assembly 7 for blocking and filtering impurities and solid particles in the aramid fiber slurry is provided at the top and inside of the filter tank 1. A stirring assembly 8 for stirring the aramid fiber slurry is provided at the top of the top cover 2 and inside the filter assembly 7. Specifically, the top cover 2 and the telescopic end of the electric push rod 3 can be installed and removed by bolts, allowing the filter assembly 7 to be installed inside the filter tank 1. At this time, the electric push rod 3... The top cover 2 moves vertically downwards, thereby sealing the top opening of the filter tank 1. Aramid fiber slurry is added into the filter tank 1 and filter assembly 7 through the feed pipe 4. The agitator 8 agitates the aramid fiber slurry, causing it to rise from the bottom of the filter assembly 7. After reaching a certain height, the aramid fiber slurry falls, thus achieving agitation. During agitation, the filter assembly 7 filters the aramid fiber slurry, blocking and filtering impurities and solid particles. The filter assembly 7 separates the impurities and solid particles from the cleaning liquid. The control valve 6 is opened, allowing the cleaning liquid to be discharged through the outlet pipe 5. The filter assembly 7 is easy to clean, allowing personnel to easily clean its interior, thereby improving work efficiency.

[0025] like Figures 2 to 4As shown, the filter assembly 7 includes a filter cartridge 701 and an annular groove 703. The filter cartridge 701 is located inside the filter tank 1. The annular groove 703 is formed at the top of the filter tank 1. A limiting ring 702 is fixedly provided on the surface of the filter cartridge 701, and the limiting ring 702 is adapted to the annular groove 703. A movable groove 704 is formed on the inner wall of the filter cartridge 701. A movable block 705 is slidably provided on the inner wall of the movable groove 704. A filter plate 706 is fixedly provided on one side of the movable block 705. A T-shaped rod 707 is fixedly installed at the top; specifically, a limiting ring 702 is partially embedded into the interior of an annular groove 703, thereby realizing the installation of filter cartridge 701 and filter tank 1. Filter cartridge 701 and limiting ring 702 can filter impurities and solid particles in aramid fiber slurry. When relevant personnel clean the interior of filter cartridge 701 and the surface of filter plate 706, filter cartridge 701 is disassembled. At this time, the T-shaped rod 707 is pulled, causing the movable block 705 to slide vertically upward, thereby causing the filter plate 706 to move vertically upward.

[0026] like Figure 3 , Figure 4 As shown, the movable groove 704, movable block 705 and T-shaped rod 707 are each provided in two sets, and the opposite surfaces of the two sets of movable blocks 705 are fixedly connected to the surface of the filter plate 706; specifically, by simultaneously pulling the two sets of T-shaped rods 707, the two sets of movable blocks 705 slide at the same time, thereby enabling the filter plate 706 to move vertically smoothly.

[0027] like Figure 3 , Figure 4 As shown, the filter plate 706 is adapted to the filter cylinder 701, and the surface of the filter plate 706 is fitted to the inner wall of the filter cylinder 701. Specifically, when the filter plate 706 is moved to the top opening of the filter cylinder 701, the filter plate 706 can rub against the inner wall of the filter cylinder 701 when it moves longitudinally, thereby cleaning the inner wall of the filter cylinder 701, which facilitates the cleaning of the inner wall of the filter cylinder 701 and the surface of the filter plate 706 by relevant personnel.

[0028] like Figure 1 , Figure 2 As shown, the stirring assembly 8 includes a motor 801. The top of the top cover 2 is fixedly equipped with the motor 801, and the bottom of the top cover 2 is equipped with a stirring rod 802. The top end of the stirring rod 802 penetrates the surface of the top cover 2 and is fixedly connected to the output end of the motor 801. The stirring rod 802 is located inside the filter cartridge 701. Specifically, when the motor 801 is started, the stirring rod 802 rotates. When the stirring rod 802 rotates, the aramid fiber slurry inside the filter cartridge 701 flows, thereby achieving the stirring of the aramid fiber slurry.

[0029] like Figure 1 , Figure 2As shown, the stirring rod 802 is spirally arranged and is adapted to the filter cylinder 701. Specifically, the rotation of the stirring rod 802 causes the aramid fiber slurry inside the filter cylinder 701 to flow, and at the same time, it causes the aramid fiber slurry inside the filter cylinder 701 to be transported from bottom to top, thereby improving the stirring effect on the aramid fiber slurry.

[0030] In summary: The telescopic ends of the top cover 2 and the electric push rod 3 can be installed and removed with bolts, allowing the filter assembly 7 to be installed inside the filter tank 1. The electric push rod 3 then moves the top cover 2 vertically downwards, sealing the top opening of the filter tank 1. Aramid fiber slurry is added to the filter tank 1 and filter assembly 7 through the feed pipe 4. The stirring assembly 8 agitates the aramid fiber slurry, causing it to rise from the bottom of the filter assembly 7. After reaching a certain height, the aramid fiber slurry falls, thus achieving agitation. During agitation, the filter assembly 7 filters the aramid fiber slurry, blocking and filtering impurities and solid particles. The filter assembly 7 separates these impurities and solid particles from the cleaning liquid. The control valve 6 is opened, allowing the cleaning liquid to be discharged through the discharge pipe 5. Furthermore, the filter assembly 7 is easy to clean, allowing personnel to conveniently clean its interior, thereby improving work efficiency.
