Technical Field

[0001] The utility model relates to the technical field of slurry filtration, in particular to a slurry filtration system. Background Art

[0002] Aramid fiber is a high-performance synthetic fiber with excellent strength, heat resistance and chemical corrosion resistance. This fiber is made of polyaramid polymer materials, of which the two most famous aramid fibers are poly-m-phenylenediamine and poly-terephthalamide. During the production process of aramid fiber, the pre-spinning slurry needs to be filtered. The current pre-spinning filtration system has a short service life, especially when the filter rod needs to be removed and replaced, it needs to be shut down.

[0003] However, during the use of the existing filtration system, the machine needs to be shut down for replacement of the filter rod, which requires 3-4 people and takes a long time to replace. After the replacement, the small filter tank also needs to circulate and degas to expel bubbles, which takes about 2-3 hours. The replacement also wastes raw materials and affects production capacity. Therefore, those skilled in the art provide a slurry filtration system to solve the problems raised in the above background technology. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a slurry filtration system, including a recovery slurry storage tank 1, a mounting pipe 2 is fixed on the outside of the recovery slurry storage tank 1, a connecting pipe 3 is connected to the top of the mounting pipe 2, a slurry gear pump outlet main pipe 4 is fixed to the top of the connecting pipe 3, four high-pressure filter element tanks 5 are installed on the top of the slurry gear pump outlet main pipe 4, a metal pipe 6 is connected to the top of the high-pressure filter element tank 5, an auxiliary maintenance device 7 is arranged on the top of the high-pressure filter element tank 5, a positioning connection device 8 is installed at the bottom of the slurry gear pump outlet main pipe 4, and a connecting metal pipe 9 is connected to the bottom of the mounting pipe 2;

[0023] The auxiliary maintenance device 7 includes a fixed shell 71, a fixed bracket 72 is fixed to the inner bottom wall of the fixed shell 71, a through hole is opened inside the fixed shell 71, and the size of the through hole is adapted to the size of the metal pipe 6, a guide metal column 73 is fixedly connected between the inner walls on both sides of the fixed shell 71, and two movable mounting sleeves 74 are movably sleeved on the outer side of the guide metal column 73, and a first tension spring 75 is arranged between the corresponding surfaces of the two movable mounting sleeves 74, and a rotating bracket 76 is rotatably connected to the outer side of the movable mounting sleeve 74 through a rotating shaft, and one end of the rotating bracket 76 is rotatably connected to a movable bracket 77 through a rotating shaft, and a positioning reinforcement sleeve 78 is fixed to one side of the movable bracket 77, and the fixed shell 71 and the high-pressure filter element tank 5 are fixedly connected, and a through groove for accommodating the movement of the rotating bracket 76 is opened inside the movable bracket 77.

[0024] During the use of this device, when in use, four high-pressure filter cartridge tanks 5 are installed on the main outlet pipeline 4 of the slurry gear pump, two of which are used and two are used as spares. Remote pressure gauges are installed on the feed pipeline and the discharge pipeline. In order to ensure the stable pressure control of the slurry before spinning through the pipeline, the feed from the side of each high-pressure filter is controlled by a DN100 pipeline plus a DN100 ball valve, and the discharge from the top of the high-pressure filter is controlled by a DN100 pipeline plus a DN100 ball valve. This reduces the formation of bubbles and can also well control the service life of each high-pressure filter cartridge tank 5. In order to facilitate the disassembly of the high-pressure filter cartridge tank 5, an overhead crane is installed above the high-pressure filter cartridge tank 5, and a slip-on flange is installed on the high-pressure filter cartridge tank 5. A DN20 or DN15 nitrogen pipeline plus a ball valve is connected to the pipeline for subsequent purging control. A DN50 pipeline is connected to the bottom of the high-pressure filter cartridge tank 5. It is passed to a small storage tank for recycling slurry, and at the same time, the fixed shell 71 and the high-pressure filter element tank 5 are fixedly connected. When the metal pipe 6 is connected to the high-pressure filter element tank 5, the first tension spring 75 in the fixed shell 71 can provide elastic force to pull the movable mounting sleeve 74, so that the movable mounting sleeve 74 drives one end of the rotating bracket 76 to move, and the other end of the rotating bracket 76 can drive the movable bracket 77 to move, so that the corresponding surface of the positioning reinforcement sleeve 78 on the outside of the movable bracket 77 fits with the outside of the metal pipe 6, ensuring that the connection between the high-pressure filter element tank 5 and the metal pipe 6 is stable and not loose. The service life of the high-pressure filter element tank 5 is 3 months. Each time the filter element is replaced, the normal production of spinning is not affected. Switching to the spare high-pressure filter element tank 5 can maintain normal production. The replacement time is about 2 hours through the overhead crane operation. The slurry with impurities in the filter element tank can be recovered to the spare slurry tank.

The second tension spring 86 can pull the mobile gold brush machine 83 to move, so that the mobile gold brush machine 83 drives one end of the positioning sleeve 82 to move, and makes the corresponding surface of the positioning sleeve 82 close to the outside of the connecting pipeline 3, thereby enhancing the connection stability between the connecting pipeline 3 and the slurry gear pump outlet main pipeline 4.
