DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0020] Combination Figure 1-Figure 4 In this embodiment, the impregnation device for filter cloth processing includes an impregnation tank 1, and an impregnation transmission roller 2 is symmetrically arranged at a position inside the impregnation tank 1. An electric hydraulic cylinder 12 is installed on one side of the impregnation tank 1 through a support plate 11. The output end of the electric hydraulic cylinder 12 is connected to a movable frame 3. The electric hydraulic cylinder 12 controls the movable frame 3 to move up and down. The movable frame 3 includes a connecting frame 31, a liquid guide pipe 32, a tension roller 33, a liquid pump 34 and a filtering pipe 35. The lower end of the connecting frame 31 is fixedly connected to the liquid guide pipe 32, and the connecting frame 31 is directly connected to the output end of the electric hydraulic cylinder 12. Due to the asymmetrical arrangement of the liquid guide pipe 32, the connection position of the electric hydraulic cylinder 12 and the connecting frame 31 is not in the center, but at the balance point of the connecting frame 31. When the pressure cylinder 12 is working, it can keep the position of the connecting frame 31 horizontal. The liquid guiding pipe 32 is sleeved with an elastic roller 33 at a position parallel to the impregnation transmission roller 2. The elastic roller 33 can rotate on the liquid guiding pipe 32. The filter cloth body 4 passes over the elastic roller 33. The liquid guiding pipe 32 is controlled to move up and down by the electric hydraulic cylinder 12, which can drive the elastic roller 33 to move up and down to control the tightness of the filter cloth body 4. The lower end of the liquid guiding pipe 32 is connected to a liquid pump 34, and the other end of the liquid guiding pipe 32 is provided with a filter pipe 35. The input end of the liquid pump 34 is placed in the impregnation liquid. When working, the liquid pump 34 extracts the impregnation liquid, and the impregnation liquid passing through the liquid guiding pipe 32 is filtered in the filter pipe 35 to remove impurities and extend the service life of the impregnation liquid.

[0021] In this embodiment, a filter cloth inlet 13 and a filter cloth outlet 14 are provided on the side wall of the immersion tank 1, and a rotatable guide roller 15 is provided at the lower end of the filter cloth inlet 13 and the filter cloth outlet 14. Under the action of the guide roller 15, the filter cloth can be easily entered and removed from the immersion tank 1.

[0022] In this embodiment, stirring paddles 21 are connected to both ends of the impregnation drive roller 2. Two impregnation drive rollers 2 are provided. A driving motor 22 is provided at one end of the impregnation drive roller 2. The driving motor 22 controls the rotation of the impregnation drive roller 2. The stirring paddles 21 at both ends rotate synchronously to stir and mix the impregnation liquid to ensure the uniformity of the impregnation liquid.

[0023] In this embodiment, a first slot 321 is provided inside one end of the liquid guiding pipe 32 close to the filter pipe 35. The liquid guiding pipe 32 is connected to the filter pipe 35 via a flange. The filter pipe 35 is a detachable structure to facilitate cleaning of filtered impurities.

[0024] In this embodiment, a second slot 351 is provided at one end of the filter pipe 35 close to the liquid guiding pipe 32, and the second slot 351 is engaged with a conical filter screen 352, and a sealing ring 3521 is connected to the conical filter screen 352, and the sealing ring 3521 is engaged with the first slot 321 and the second slot 351 at the same time. After the conical filter screen 352 is installed on the filter pipe 35, the sealing ring 3521 protrudes from the surface of the filter pipe 35, and then the filter pipe 35 is connected to the liquid guiding pipe 32. The protruding sealing ring 3521 can strengthen the connection tightness between the liquid guiding pipe 32 and the filter pipe 35, and also facilitate the disassembly of the conical filter screen 352. The lower end of the filter pipe 35 is immersed in the immersion liquid or adheres to the surface of the immersion liquid to avoid spraying when the immersion liquid falls.

[0025] Preferably, a guide plate 16 is provided on the inner wall of the immersion tank 1, and a guide hole matching the liquid guiding pipe 32 is opened on the guide plate 16. The guide hole is sleeved on one end of the liquid guiding pipe 32 connected to the liquid pump 34. When the liquid guiding pipe 32 moves up and down, the guide plate 16 limits the liquid guiding pipe 32 from tilting, and the liquid pump 34 is placed below the guide plate 16. The guide plate 16 can be set as a standard water level line. When the liquid guiding pipe 32 moves up and down, the liquid pump 34 is always located below the liquid surface. When the immersion liquid is lower than the guide plate 16, it is reminded to add immersion liquid.

[0026] Working process: the filter cloth body 4 to be impregnated passes through the filter cloth inlet 13, the impregnation drive roller 2, the tension roller 33, the impregnation drive roller 2 and the filter cloth outlet 14 in sequence, the electric hydraulic cylinder 12 controls the connecting frame 31 to move up, the tension roller 33 tightens the filter cloth body 4, the impregnation drive roller 2 is turned on, and the impregnation starts. The filter cloth body 4 is moved out after being impregnated twice in the impregnation tank 1. During the process, the stirring paddles 21 at both ends of the impregnation drive roller 2 stir and mix the impregnation liquid to ensure the uniformity of the impregnation liquid. At the same time, the liquid pump 34 takes the impregnation liquid in the impregnation tank 1, and the impregnation liquid passing through the liquid guide pipe 32 is filtered in the filter pipe 35 to remove impurities, and then discharged back to the impregnation tank 1 by the filtered pipe 35. After filtering for a period of time, the filter pipe 35 is disassembled and the conical filter screen 352 is cleaned.

[0027] In summary, in the impregnation device for filter cloth processing of the utility model, the support structure of the tension roller 33 is set to the structure of the liquid guiding pipe 32, and the liquid pump 34 and the filter pipe 35 are connected at both ends of the liquid guiding pipe 32, so that the impregnation liquid in the impregnation tank 1 can be continuously circulated and filtered through the conical filter screen 352, thereby reducing the content of impurities in the impregnation liquid and extending the service life of the impregnation liquid. In addition, both ends of the impregnation drive roller 2 are connected with stirring paddles 21. When the impregnation drive roller 2 is working, the impregnation liquid is stirred and mixed to ensure the uniformity of the impregnation liquid and the impregnation quality.
