Description

Technical Field

[0001] This utility model relates to the field of material modification equipment technology, and in particular to a surface modification equipment for glass fiber composite membrane materials. Background Technology

[0002] Fiberglass cloth, as a fiber composite material, is a widely used industrial raw material in developed countries around the world. It is characterized by its light weight, high strength, high modulus, high temperature resistance (up to 2000℃), corrosion resistance, and fatigue resistance, which are significantly higher than those of steel and aluminum.

[0003] Chinese patent application CN201110035560.7 discloses a method for surface modification of polymer membranes using a micro-swelling method, comprising the following steps: mixing a good solvent for the polymer membrane with a poor solvent to form a mixed solution; immersing the polymer membrane in the mixed solution at a certain temperature for a certain time; and rinsing with pure water after immersion. This method improves the hydrophilicity and surface smoothness of the polymer membrane, increases the water flux of the membrane, and provides a new approach and method for polymer membrane surface modification.

[0004] When modifying polymer membranes using this method, the membrane material needs to be immersed in a liquid tank for an extended period. This tank typically contains two pressure rollers that press the immersed membrane material to the water surface. Although a portion of the membrane material is pressed into the tank, the length of material immersed is limited because the pressure rollers only restrict the material from both ends. When dealing with membrane materials that are continuously transported using a winding method, a significant amount of material remains outside the tank, requiring multiple immersions. Therefore, this method suffers from low immersion efficiency. This invention proposes a surface modification device for fiberglass composite membranes to address the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a surface modification device for fiberglass composite membrane materials. This device solves the problem that existing surface modification devices often leave a significant amount of membrane material outside the tank during immersion modification of membrane materials that are continuously transported via a winding method. This necessitates multiple immersions, resulting in low immersion efficiency.

[0006] To achieve the purpose of this utility model, the utility model is achieved through the following technical solution: a surface modification device for fiberglass composite membrane material, including a pool body and a winding device and an unwinding device provided on both sides of the pool body, the unwinding device including a first washing pool, an soaking pool and a second washing pool;

[0007] The first washing tank is located on the side of the soaking tank near the unwinding device, and the second washing tank is located on the side of the soaking tank near the winding device. Both the first and second washing tanks are equipped with washing rollers for pressing the film material into the water.

[0008] The soaking tank is equipped with multiple upper guide rollers and multiple lower pressure rollers. Each lower pressure roller is located below each upper guide roller and is staggered from each upper guide roller. Each lower pressure roller is installed at the bottom of the soaking tank and forms a W-shape with the position of each upper guide roller.

[0009] A further improvement is that a liquid injection device is provided on the outside of the soaking pool. The liquid injection device includes a liquid injection pump. The output end of the liquid injection pump is connected to a liquid injection pipe. The end of the liquid injection pipe away from the liquid injection pump is connected to a water injection port opened on the wall of the soaking pool. The input end of the liquid injection pump is connected to a mixed solvent tank located outside the soaking pool.

[0010] A further improvement is that the bottom walls of the first washing pool, the soaking pool, and the second washing pool are all lined with drain pipes, and each drain pipe is connected to a drain pump located outside the winding device.

[0011] A further improvement is that: both the first washing tank and the second washing tank are equipped with stirring blades, and the two stirring blades are respectively installed at the bottom of the first washing tank and the second washing tank and correspond to the washing pressure roller.

[0012] A further improvement is that an oven is provided between the second washing tank and the winding device, and a drying chamber is provided inside the oven. The two sides of the drying chamber correspond to the winding device and the second washing tank, respectively. An upper air plate and a lower air plate are provided inside the drying chamber, and the upper air plate and the lower air plate are connected to the output end of the hot air fan located in the oven through pipes.

[0013] A further improvement is that the soaking tank is equipped with multiple conical cover plates, each conical cover plate is placed above each lower pressure roller and separates two adjacent upper guide rollers. The lower end of the conical cover plate is conical, and the upper end of the conical cover plate is detachably connected to the upper port of the soaking tank through a bolt plate.

[0014] A further improvement is that the inner wall of the soaking pool is provided with a water-blocking weir, which is installed around the water inlet. A diversion plate is provided inside the water-blocking weir, and the diversion plate corresponds to the water inlet.

[0015] The beneficial effects of this utility model are as follows: the film material is inserted from the washing tank into the soaking tank, and each lower pressure roller and each upper guide roller located in the soaking tank guides the film material. Since each lower pressure roller and each upper guide roller is W-shaped in the soaking tank, the film material wrapped around each lower pressure roller and upper guide roller is also W-shaped. The advantage of this arrangement is that it can effectively increase the residence time and soaking area of ​​the film material in the soaking tank, and improve the modification processing efficiency of the film material.

Detailed Implementation

[0020] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0021] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a surface modification device for glass fiber composite membrane, including a pool body and a winding device 1 and an unwinding device 2 disposed on both sides of the pool body. The unwinding device 2 includes a first washing pool 3, an immersion pool 4, and a second washing pool 5.

[0022] The first washing tank 3 is located on the side of the soaking tank 4 near the unwinding device 2, and the second washing tank 5 is located on the side of the soaking tank 4 near the winding device 1. Both the first washing tank 3 and the second washing tank 5 are equipped with washing rollers 13 for pressing the film material into the water. During processing, the film material first enters the first washing tank 3, where detergent is injected to clean impurities on the surface of the film material. After cleaning, the film material enters the soaking tank 4 for soaking. After soaking, the film material enters the second washing tank 5, where pure water is added to rinse the film material.

[0023] To further improve the cleaning effect of the membrane material, both the first washing tank 3 and the second washing tank 5 are equipped with stirring blades 8. The two stirring blades 8 are respectively installed at the bottom of the first washing tank 3 and the second washing tank 5 and correspond to the washing pressure roller 13. When washing the membrane material, the waterproof motor in the first washing tank 3 and the second washing tank 5 will be started, driving the stirring blades 8 to rotate. The stirring blades 8, by rotating, agitate the washing water in the first washing tank 3 and the second washing tank 5, and the flowing water will more effectively wash the surface of the membrane material.

[0024] The soaking tank 4 is equipped with multiple upper guide rollers 15 and multiple lower pressure rollers 14. Each lower pressure roller 14 is positioned below and offset from each upper guide roller 15, and is installed at the bottom of the soaking tank 4, forming a W-shape with respect to the upper guide rollers 15. The membrane material enters the soaking tank 4 from the first washing tank 3, and the lower pressure rollers 14 and upper guide rollers 15 within the soaking tank 4 guide the membrane material. Because the lower pressure rollers 14 and upper guide rollers 15 are arranged in a W-shape within the soaking tank 4, the membrane material wrapped around them is also arranged in a W-shape. This arrangement effectively increases the residence time and soaking area of ​​the membrane material within the soaking tank 4, thereby improving the membrane material modification efficiency.

[0025] More specifically, a liquid injection device is installed on the outside of the soaking tank 4. This device includes a liquid injection pump 11, the output of which is connected to an injection pipe. The end of the injection pipe away from the pump 11 is connected to a water inlet 12 located on the wall of the soaking tank 4. The input end of the pump 11 is connected to a mixed solvent tank located outside the soaking tank 4. The modified solvent is injected into the soaking tank 4 via the pump 11. The polymer membrane is then placed in a mixed solvent containing a small amount of good solvent and a large amount of poor solvent. Some of the good solvent molecules diffuse between the polymer chain segments, increasing the distance between the surface polymer chains. In addition to the soaking tank 4, liquid injection devices are also installed on the outside of the first washing tank 3 and the second washing tank 5 to replace the accumulated water in them.

[0026] The bottom walls of the first washing tank 3, soaking tank 4, and second washing tank 5 are all lined with drain pipes 9, each of which is connected to a drain pump 10 located outside the winding device 1. The first washing tank 3, soaking tank 4, and second washing tank 5 are drained by independent drain pumps 10, so they will not interfere with each other.

[0027] More specifically, an oven 6 is provided between the second washing tank 5 and the winding device 1. A drying chamber 7 is located inside the oven 6. The two ends of the drying chamber 7 correspond to the winding device 1 and the second washing tank 5, respectively. An upper air plate and a lower air plate are installed inside the drying chamber 7, and these plates are connected to the output end of a hot air blower located inside the oven 6 via pipes. After the film material is rinsed in the second washing tank 5, it passes through the drying chamber 7. The upper and lower air plates are located on the upper and lower ends of the film material, and the hot air generated by them dries the film material. It should be noted that the temperature of the drying airflow should not be too high. Additionally, a drying device can also be installed between the first washing tank 3 and the soaking tank 4 to dry the washing liquid remaining on the surface of the film material before immersion in the soaking tank 4.

[0028] It should be noted that rollers for guiding the membrane material are installed on the upper surface of the first washing tank 3, the soaking tank 4, and the second washing tank 5, in the direction of the inlet and outlet of the membrane material, and at both ends of the drying chamber 7.

[0029] Please see Figure 3 In a preferred embodiment, the soaking tank 4 is provided with multiple conical cover plates 16. Each conical cover plate 16 is positioned above each lower pressure roller 14 and separates two adjacent upper guide rollers 15. The lower end of each conical cover plate 16 is conical, and the upper end of each conical cover plate 16 is detachably connected to the upper port of the soaking tank 4 via a bolt plate 17. Each conical cover plate 16 is located on both sides of each upper guide roller 15, and its lower end extends above the lower pressure roller 14, dividing the space inside the soaking tank 4. The advantage of this arrangement is that it is not necessary to inject too much solution to completely cover the membrane material penetrating into the soaking tank 4.

[0030] The mixed solution is added into the soaking tank 4 through the water inlet 12. When the liquid gushes out from the water inlet 12, due to water pressure and the difference in water level between the water surface and the water inlet 12, the solution injected into the soaking tank 4 easily splashes out of the soaking tank 4. Please refer to [link / reference]. Figure 3 In a preferred embodiment, the inner wall of the soaking tank 4 is provided with a water-retaining weir 18, which is installed around the water inlet 12. A diversion plate 19 is provided inside the water-retaining weir 18, corresponding to the water inlet 12. The liquid flowing from the water inlet 12 first flows into the water-retaining weir 18, and the diversion plate 19 blocks the water flow. The blocked liquid continuously overflows from the edge of the water-retaining weir 18, effectively preventing splashing during liquid filling.

[0031] This surface modification equipment for fiberglass composite membranes, based on traditional modification equipment, includes a washing tank on each side of an immersion tank 4. The immersion tank 4 contains multiple upper guide rollers 15 and multiple lower pressure rollers 14. Each lower pressure roller 14 is positioned below and offset from each upper guide roller 15, and is installed at the bottom of the immersion tank 4, forming a W-shape with respect to the upper guide rollers 15. The membrane material enters the immersion tank 4 from the washing tank, and the lower pressure rollers 14 and upper guide rollers 15 guide the membrane material. Because the lower pressure rollers 14 and upper guide rollers 15 are W-shaped within the immersion tank 4, the membrane material wrapped around them also forms a W-shape. This arrangement effectively increases the residence time and immersion area of ​​the membrane material in the immersion tank 4, improving the modification efficiency of the membrane material.
