Description

Technical Field

[0001] This utility model relates to the technical field of glass fiber production, and more specifically, to a rapid switching system for impregnating agents. Background Technology

[0002] In the production of glass fiber, sizing agents are commonly used; these are specialized chemical agents that wet the surface of glass fibers. Film-forming agents in sizing agents can form a tough and elastic film layer on the glass fiber surface, enhancing the fiber's bundle structure and abrasion resistance. Coupling agents can improve the bond strength between the glass fiber and the matrix material, allowing it to better perform its reinforcing function. Lubricants help reduce the coefficient of friction of the glass fiber during production, improving production efficiency.

[0003] In the specific production process, the prepared impregnating agent is first sent to the storage tank, and then enters the circulation tank. The impregnating agent in the circulation tank enters the oiling box (the impregnating agent in the oiling box directly contacts the glass and plays a role in the glass fiber production process). Some of the impregnating agent in the oiling box will flow back to the circulation tank, be filtered, and then return to the oiling box. During the whole process, the impregnating agent itself will produce some sediment and agglomeration, and the impregnating agent returning from the oiling box will carry impurities such as glass fibers. Long-term circulation will clog the filter device and reduce the quality of the impregnating agent. Therefore, the circulation tank and filter device need to be cleaned regularly. The cleaning process usually requires shutdown maintenance, which will have a certain impact on production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a rapid wetting agent switching system that can clean components such as filter devices without interrupting the supply of wetting agent.

[0005] This utility model is achieved through the following technical solution: The rapid switching system for wetting agents of this utility model includes a main pipe, a storage tank, a pump body, a circulation tank, a filter device, and an oiling box sequentially arranged on the main pipe, a return pipe for connecting the circulation tank and the oiling box, a first valve arranged between the pump body and the circulation tank, a second valve arranged between the filter device and the oiling box, a first tee pipe arranged between the pump body and the first valve, a second tee pipe arranged between the second valve and the oiling box, and a branch pipe for connecting the first tee pipe and the second tee pipe.

[0006] Furthermore, bypass valves are provided at both ends of the branch pipe.

[0007] Furthermore, the branch pipe has a U-shaped structure, and a third tee pipe is provided on the lower side of the middle part of the branch pipe, and a third valve is provided on the third tee pipe.

[0008] Furthermore, the branch pipe is detachably connected to the first tee pipe and the second tee pipe.

[0009] Furthermore, a buffer tank is provided on the return pipe.

[0010] Furthermore, a fourth valve is provided between the buffer tank and the circulation tank.

[0011] Furthermore, the buffer tank is a vertically arranged columnar structure, and the return pipe is connected to the lower side wall of the buffer tank; the upper end of the buffer tank is provided with an exhaust pipe, and the exhaust pipe is provided with a fifth valve.

[0012] Furthermore, a counterweight is provided inside the buffer tank in a sealed sliding manner.

[0013] Furthermore, the upper side wall of the buffer tank is provided with an overflow pipe; the distance between the overflow pipe and the inner top wall of the buffer tank is greater than the thickness of the counterweight.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In the rapid switching system for the wetting agent of this utility model, the wetting agent in the storage tank enters the circulation tank through the pump body during use, then enters the filter device through the circulation tank, and after filtration, enters the oiling box. Part of the wetting agent in the oiling box flows back to the circulation tank through the return pipe, and after passing through the filter device again, returns to the oiling box, completing the utilization and circulation of the wetting agent. When a large amount of wetting agent sediment, agglomerates, glass fibers, and other impurities accumulate in the circulation tank and filter device, the circulation tank and filter device can be disconnected from the main pipe by closing the first and second valves. This allows the wetting agent to directly enter the oiling box through the branch pipe for a short time. During this period, the circulation tank and filter device can be opened for cleaning and replacement, and the normal flow of the wetting agent is not interrupted throughout the process. Therefore, the circulation tank, filter device, and other related components can be processed while ensuring the normal supply of the original wetting agent. Attached Figure Description

Detailed Implementation

[0018] Example

[0019] The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 -Appendix Figure 2 As shown, the rapid switching system for wetting agents in this embodiment includes a main pipe 10, a storage tank 11, a pump body 12, a circulation tank 13, a filter device 14, and an oiling box 15 sequentially disposed on the main pipe 10, a return pipe 16 for connecting the circulation tank 13 and the oiling box 15, a first valve 17 disposed between the pump body 12 and the circulation tank 13, a second valve 18 disposed between the filter device 14 and the oiling box 15, a first tee pipe 22 disposed between the pump body 12 and the first valve 17, a second tee pipe 23 disposed between the second valve 18 and the oiling box 15, and a branch pipe 21 for connecting the first tee pipe 22 and the second tee pipe 23. Specifically, during use, the wetting agent in the storage tank 11 enters the circulation tank 13 through the pump body 12, then enters the filter device 14 through the circulation tank 13, and after filtration, enters the oiling box 15. Part of the wetting agent in the oiling box 15 flows back to the circulation tank 13 through the return pipe 16, and then returns to the oiling box 15 after passing through the filter device 14, completing the utilization and circulation of the wetting agent. When a large amount of wetting agent sediment, agglomerates, glass fibers, and other impurities accumulate in the circulation tank 13 and the filter device 14, the circulation tank 13 and the filter device 14 can be disconnected from the main pipe 10 by closing the first valve 17 and the second valve 18. This allows the wetting agent to directly enter the oiling box 15 through the branch pipe 21 for a short period. During this time, the circulation tank 13 and the filter device 14 can be opened for cleaning and replacement, and the normal flow of the wetting agent will not be interrupted. Therefore, the circulation tank 13, the filter device 14, and other related components can be processed while ensuring the normal supply of the original wetting agent.

[0020] In this embodiment, both ends of the branch pipe 21 are equipped with bypass valves 24. Specifically, when the circulation tank 13 and the filter device 14 are not being cleaned, the bypass valves 24 can be closed to prevent the wetting agent from flowing through the branch pipe 21.

[0021] In this embodiment, the branch pipe 21 has a U-shaped structure, with a third tee pipe 25 located on the lower side of the middle section. A third valve 26 is installed on the third tee pipe 25. Specifically, when the circulation tank 13 and the filter device 14 are not being cleaned, the third valve 26 can be opened, allowing the wetting agent in the branch pipe 21 to flow out completely through the third tee pipe 25 and the third valve 26. This prevents a large amount of wetting agent from remaining in the branch pipe 21 for an extended period, thus avoiding sedimentation and clumping. Furthermore, cleaning agent can be sprayed into the branch pipe 21 through the third tee pipe 25 to clean it, preventing wetting agent residue in the branch pipe 21.

[0022] In this embodiment, the branch pipe 21 is detachably connected to the first tee pipe 22 and the second tee pipe 23. Specifically, when not in use for a long time, the branch pipe 21 can be directly removed.

[0023] In this embodiment, a buffer tank 31 is provided on the return pipe 16. A fourth valve 32 is provided between the buffer tank 31 and the circulation tank 13. Specifically, the wetting agent returning from the oiling box 15 to the circulation tank 13 first flows into the buffer tank 31 and then flows back into the circulation tank 13. When it is necessary to clean the circulation tank 13 and the filter device 14, the fourth valve 32 can be closed, so that the wetting agent returning from the oiling box 15 is temporarily stored in the buffer tank 31.

[0024] In this embodiment, the buffer tank 31 is a vertically arranged columnar structure, with the return pipe 16 connected to the lower side wall of the buffer tank 31. An exhaust pipe 33 is located at the upper end of the buffer tank 31, and a fifth valve 34 is installed on the exhaust pipe 33. A counterweight 35 is slidably and sealed inside the buffer tank 31. Specifically, when the circulation tank 13 and the filter device 14 are not being cleaned, the counterweight 35 in the buffer tank 31 compresses the wetting agent, preventing it from entering the upper space of the buffer tank 31. When cleaning of the circulation tank 13 and the filter device 14 is required, the fourth valve 32 is closed, the wetting agent accumulates in the buffer tank 31, and the fifth valve 34 is opened. The wetting agent pushes the counterweight 35 upwards, and the gas inside the buffer tank 31 is discharged through the exhaust pipe 33, allowing the wetting agent to fill the buffer tank 31. After cleaning, the fourth valve 32 is opened, and under the pressure of the counterweight 35, the wetting agent in the buffer tank 31 is forced into the circulation tank 13.

[0025] In this embodiment, the upper side wall of the buffer tank 31 is provided with an overflow pipe 36; the distance between the overflow pipe 36 and the inner top wall of the buffer tank 31 is greater than the thickness of the counterweight 35. Specifically, when the buffer tank 31 is insufficient to hold the wetting agent, the excess wetting agent can be discharged directly through the overflow pipe 36, and a valve can be installed on the overflow pipe 36.

[0026] In summary, in this embodiment of the rapid switching system for the wetting agent, during use, the wetting agent in the storage tank 11 enters the circulation tank 13 through the pump body 12, then enters the filter device 14 through the circulation tank 13, and after filtration, enters the oiling box 15. Part of the wetting agent in the oiling box 15 will flow back to the circulation tank 13 through the return pipe 16, and after passing through the filter device 14, return to the oiling box 15, thus completing the utilization and circulation of the wetting agent. After a large amount of impurities such as sediment, clumps, and glass fibers accumulate in the circulation tank 13 and the filter device 14, the circulation tank 13 and the filter device 14 can be cut off from the main pipe 10 by closing the first valve 17 and the second valve 18. This allows the impurity to enter the oiling box 15 directly through the branch pipe 21 for a short period of time. During this period, the circulation tank 13 and the filter device 14 can be opened for cleaning, replacement, etc., and the normal flow of the impurity will not be interrupted throughout the process. Therefore, the circulation tank 13, the filter device 14 and other related components can be processed while ensuring the normal supply of the original impurity.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
