[0023] The outer surface of the fixed plate 2 is provided with the flow guide cylinder 7, the top end and the bottom end of the flow guide cylinder 7 are connected with sealing covers 8 through bolts, the bottom of the sealing cover 8 is detachably connected with a gasket 9, the other end of the gasket 9 abuts against the end of the flow guide cylinder 7, a flow guide pipe 10 is inserted into the outer wall of the sealing cover 8, a fixed cylinder 11 is threadedly connected to one end of the flow guide pipe 10, a filter screen 12 is fixedly connected to the outer surface of the fixed cylinder 11, a flow guide cavity 13 is formed in the middle of the inner wall of the fixed cylinder 11, a plurality of drainage holes 14 are formed in the outer surface of the flow guide cavity 13, a sealing plug 15 is threadedly connected to the end of the fixed cylinder 11 away from the flow guide pipe 10, and the flow guide cylinder 7 is a key channel for the flow of the film stripping solution, guiding the film stripping solution to flow in the device according to the predetermined route, and the internal space provides a relatively closed and regular path for the transmission of the film stripping solution, so that the film stripping solution can flow to each treatment link in an orderly manner, avoiding the low treatment efficiency caused by the turbulent flow of the liquid or the uneven washing of the internal components of the device, and laying a foundation for the subsequent ion exchange process.

[0024] The sealing cover 8 is installed at the top and bottom ends of the flow guide cylinder 7, and is detachable through bolt connection. The main function is to seal the flow guide cylinder 7, prevent the stripping solution from leaking, maintain the stability of the internal pressure of the device, and ensure that the stripping solution flows in the specified flow channel. At the same time, the sealing cover 8 provides a mounting base for other components such as the flow guide pipe 10, the gasket 9, etc., to ensure the integrity and sealing of the end structure of the entire flow guide cylinder 7. The gasket 9 is located at the bottom of the sealing cover 8 and tightly abuts against the end of the flow guide cylinder 7, further enhancing the sealing effect. It can fill the small gaps that may exist between the sealing cover 8 and the flow guide cylinder 7, effectively preventing the stripping solution from leaking, protecting the surrounding environment of the device from corrosion by the stripping solution, and ensuring the stability of the internal fluid mechanics environment of the device, which is conducive to the accurate performance of ion exchange. The flow guide pipe 10 serves as a channel for the stripping solution to enter and exit the flow guide cylinder 7, and introduces the external stripping solution into the flow guide cylinder 7 or leads the treated stripping solution to the subsequent process. Its reasonable pipe diameter design can adapt to different flow requirements, ensuring smooth transportation of the stripping solution. At the same time, through threaded connection with the fixed cylinder 11 and the connecting seat 17, etc., it is convenient to install, disassemble and maintain, making the entire pipeline system highly flexible. The fixed cylinder 11 is one of the core components for achieving uniform distribution of the stripping solution. The filter screen 12 on the outer surface of the fixed cylinder 11 can preliminarily filter out large particulate impurities in the stripping solution, preventing them from entering the flow guide cavity 13 and the subsequent ion exchange resin layer, and protecting the resin from physical damage.

[0025] The flow guide cavity 13 in the middle of the inner wall and the multiple drainage holes 14 opened on the outer surface work together to uniformly disperse the incoming stripping solution into the device, allowing the ion exchange resin to fully contact the stripping solution and improving the ion exchange efficiency. The filter screen 12 filters out particulate impurities such as metal debris, dust, and undissolved organic particles from the stripping solution, preventing these impurities from entering the flow guide cavity 13, the drainage holes 14, or the ion exchange resin layer. The flow guide cavity 13 serves as a buffer and distributor for the stripping solution. When the stripping solution flows into the fixed cylinder 11 from the flow guide pipe 10, the flow guide cavity 13 first temporarily stores and preliminarily distributes the liquid, making the pressure of the stripping solution uniform. Then, through the drainage holes 14 connected to it, the stripping solution is uniformly sprayed into the device, achieving uniform distribution of the stripping solution throughout the device and creating conditions for efficient ion exchange. The drainage holes 14 uniformly disperse the stripping solution in the flow guide cavity 13 into the device. The design of multiple drainage holes 14 ensures that the stripping solution flows out uniformly in all directions, making the concentration of the stripping solution around the ion exchange resin balanced and preventing local over-concentration or under-concentration. This ensures that the resin can fully exert its ion exchange function and improve the overall processing efficiency. The sealing plug 15 is installed at the end of the fixed cylinder 11 away from the flow guide pipe 10, and is used to close the opening at this end of the fixed cylinder 11. During normal operation, it prevents the stripping solution from leaking from this end, ensuring that the stripping solution can only flow along the predetermined path of the flow guide cavity 13 and the drainage holes 14, maintaining the stability of the fluid dynamics inside the device, and ensuring the standardization of the stripping solution treatment process.

[0026] The outer wall of the sealing cover 8 is connected with the cover plate 16 through bolts, the end of the flow guide pipe 10 passing through the sealing cover 8 is threadedly connected with the connecting seat 17, the other end of the connecting seat 17 is threadedly connected with the conveying pipe 18, the outer wall of the conveying pipe 18 is provided with the valve 19, the connecting seat 17 is a transition connecting component of the flow guide pipe 10 and the conveying pipe 18, which on the one hand realizes quick and reliable connection of the two through threaded connection, and facilitates replacement of conveying pipes 18 of different specifications according to actual needs; on the other hand, it plays a certain buffering and fixing role, ensures smooth transition of the membrane-removing liquid in the transmission process, reduces the risk of pressure fluctuation or leakage due to improper pipeline connection, and conveys the membrane-removing liquid from an external source to the device, or conveys the treated membrane-removing liquid to the next processing link or storage facility, cooperates with the valve 19 to accurately control the inflow and outflow of the membrane-removing liquid, meets the production needs under different working conditions, and realizes efficient and orderly operation of the entire membrane-removing liquid treatment process.
