Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figures 1 - 3, an embodiment provided by the present utility model: A membrane treatment device for producing a solvent for regenerated fiber production, including a tank body 1. A sealing cover 3 is clamped on the outer wall of the top of the tank body 1. A treatment mechanism 6 is arranged on the tank body 1 for cleaning and wiping the filter membrane to remove impurities. An auxiliary mechanism 7 is arranged on the treatment mechanism 6 for disassembling and assembling and maintaining each component of the treatment mechanism 6. The treatment mechanism 6 includes an annular frame 61. The annular frame 61 is slidably connected to the outer wall of the top of the sealing cover 3. A regulating disc 62 is fixedly connected to the outer wall of the top of the annular frame 61. By setting the regulating disc 62, it is convenient for personnel to hold and adjust the lifting and rotation of the straight rod 63. A straight rod 63 is fixedly connected to the outer wall of the bottom of the regulating disc 62. One end of the straight rod 63 away from the sealing cover 3 is fixedly connected to a filter membrane cylinder 64. By setting the filter membrane cylinder 64, the solvent for regenerated fiber production is filtered. The above structure is prior art, so no more details are described here. A top brush plate 65 is fixedly connected to the outer wall of the bottom of the sealing cover 3. By setting the top brush plate 65 to cooperate with the side brush plate 66, the surface of the filter membrane cylinder 64 is wiped and cleaned. Side brush plates 66 are fixedly connected to the outer walls on both sides of the top brush plate 65.

[0025] Refer to Figures 2 - 3 , the straight rod 63 penetrates through the inner wall of the top of the sealing cover 3. The filter membrane cylinder 64 is slidably connected to the inner wall of the side of the tank body 1. An indication mark is opened on the outer wall of the top of the regulating disc 62. By setting the indication mark, the operation method is prompted. The outer diameter of the top brush plate 65 is adapted to the outer diameter of the filter membrane cylinder 64. The side brush plate 66 is slidably connected to the outer wall of the side of the filter membrane cylinder 64. An outlet 2 is opened on the outer wall of the bottom of the tank body 1. An inlet 4 is opened on the outer wall of the top of the sealing cover 3. A pressurizing port 5 is opened on the outer wall of the top of the sealing cover 3.

[0026] Refer to Figures 3 - 4 , the auxiliary mechanism 7 includes a threaded groove 71. The threaded groove 71 is opened on the outer wall of the side of the side brush plate 66. An installation groove 72 is opened on the inner wall of the top of the tank body 1. By setting the installation groove 72 to cooperate with the threaded groove 71, the sealing cover 3 can be conveniently disassembled, and the dirt on the internal filter membrane cylinder 64 and the dirt collection tank 74 can be conveniently maintained. A dirt collection tank 74 is opened on the inner wall of the top side of the filter membrane cylinder 64. By setting the dirt collection tank 74, the dirt is collected and stored when the filter membrane cylinder 64 is wiped and cleaned. The threaded groove 71 is threadedly connected to the inner wall of the side of the installation groove 72. A groove 73 is opened on the outer wall of the side of the sealing cover 3.

[0027] Working principle: By pulling the adjusting disc 62, the annular frame 61 is driven to move. At the same time, the movement of the adjusting disc 62 drives the straight rod 63 to move, and the movement of the straight rod 63 drives the filter membrane cylinder 64 to move, so that the filter membrane cylinder 64 adheres to the top brush plate 65. Subsequently, the adjusting disc 62 is rotated to make the straight rod 63 rotate. The rotation of the straight rod 63 drives the filter membrane cylinder 64 to rotate. When the filter membrane cylinder 64 rotates, the top brush plate 65 and the side brush plate 66 wipe and clean the surface dirt, and the impurities after cleaning are washed into the dirt collection tank 74 for convenient collection and storage. When there is a large amount of long-term cleaning and storage, by rotating the adjusting disc 62, the threaded groove 71 is rotated, and the threaded groove 71 rotates and disengages from the installation groove 72, so that the sealing cover 3 is separated from the outer wall of the tank body 1. Subsequently, the components of the internal treatment mechanism 6 and the dirt in the dirt collection tank 74 are conveniently cleaned and maintained.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
