Technical Field
[0001] This utility model relates to the technical field of filtration equipment, specifically to an antibacterial hollow fiber membrane filtration device. Background Technology
[0002] Hollow fiber membranes are fibrous membranes with a self-supporting function. They are made from polyethersulfone and dimethylacetamide and processed into hollow filaments. When used in ultrafiltration modules, the feed solution flows under pressure on the outside or inside of the hollow fiber, forming external pressure type and internal pressure type hollow fiber ultrafiltration membranes, respectively.
[0003] According to a hollow fiber membrane filtration device with publication number CN218981104U, a housing is included. A filter cylinder is disposed inside the housing. Mounting blocks are fixed at both ends of the filter cylinder. A hollow fiber membrane body is fixed at the middle position of two mounting blocks. Multiple hollow fiber membrane bodies are arranged in a circumferential pattern. Water inlet holes are formed on the outer walls of each mounting block, and these water inlet holes communicate with the hollow fiber membrane bodies. Support rings are fixed at both ends inside the housing. The inner walls of the support rings contact the outer walls of the mounting blocks. One of the mounting blocks... A limiting ring is fixedly provided on the outer wall, and the limiting ring contacts the support ring. Both ends of the housing are provided with covers, and a protruding ring is fixedly provided on the inner wall of the cover, and the protruding ring contacts the outer wall of the limiting ring. When the user needs to replace the hollow fiber membrane body, he / she only needs to remove the cover to take it out, which is convenient for use. However, the device uses a large number of bolts to fix the connection between the housing and the cover, which leads to increased cost and is time-consuming and laborious in disassembly and installation. Therefore, we propose an antibacterial hollow fiber membrane filtration device to solve the above problems. Utility Model Content

[0006] As a further preferred embodiment of this technical solution, a rotating block is fixedly installed on the outer side of the pressure plate, and the rotating block is designed to be ring-shaped.
[0007] As a further preferred embodiment of this technical solution, an annular groove is provided at the top of the housing, and a sealing gasket is inserted into the annular groove, with the top of the sealing gasket protruding from the top of the housing.
[0008] As a further preferred embodiment of this technical solution, the sleeve plate is tightly attached to the outer side of the first outer bracket, and the ball block is tightly attached to the outer side of the second outer bracket.
[0009] As a further preferred embodiment of this technical solution, the thread connecting the screw and the pressure plate is a fine-pitch thread.
[0010] As a further preferred embodiment of this technical solution, the connector includes a shaft that passes through the interior of the sleeve plate and the outer bracket. A front baffle is fixedly installed at one end of the shaft, and a rear baffle is abutted at the other end of the shaft.

Through the action of the I-shaped shaft, the ball block can rotate on one side of the outer support, thus releasing the pressure and fastening of the U-shaped plate. Then, through the connecting piece, the sleeve plate and the outer support can rotate, allowing the arc-shaped cover to move away from the end of the shell, exposing both ends of the hollow fiber membrane to the outside. This allows the hollow fiber membrane to be removed from the inside of the shell. This structure is simple and easy to operate, effectively improving the operator's experience.
[0014] This utility model, by providing a connector, can restrict the rotational connection between the sleeve plate and the outer bracket. When the rear baffle is rotated, the threaded rod can disengage from the inside of the threaded hole, thereby allowing the shaft to be pulled out from the sleeve plate and the outer bracket. The sleeve plate can then be disassembled on the outside of the outer bracket to facilitate cleaning of the entire structure. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] This utility model provides a technical solution: such as Figure 1 , Figure 2 and Figure 3As shown in this embodiment, an antibacterial hollow fiber membrane filtration device includes a housing 1, a hollow fiber membrane 2 inserted inside the housing 1, an arc-shaped cover 3 abutting the top of the housing 1, a connecting box 4 fixedly disposed on the outer side of the arc-shaped cover 3, a sleeve plate 5 fixedly installed on the outer side of the arc-shaped cover 3, the sleeve plate 5 being sleeved on the outer side of an outer support 6, the outer support 6 being fixedly disposed on the outer side of the housing 1, the sleeve plate 5 and the outer support 6 being connected by a connector 7, extension plates 8 fixedly disposed on the outer sides of both the housing 1 and the arc-shaped cover 3, a U-shaped plate 9 fixedly installed on the extension plate 8 fixedly disposed on the outer side of the arc-shaped cover 3, and a U-shaped plate 9 fixedly disposed on the outer side of the housing 1. An outer bracket 2 10 is fixedly installed on the extension plate 8. A ball block 12 is inserted into the outer bracket 2 10. The outer bracket 2 10 and the ball block 12 are rotatably connected by an I-shaped shaft 11. A screw 13 is fixedly installed on the outside of the ball block 12. A pressure plate 14 is meshed with the outside of the screw 13. The pressure plate 14 is tightly attached to the U-shaped plate 9. Pipes 15 are fixedly installed on the outside of the housing 1 and on the outside of the extension plate 8. By rotating and rising the pressure plate 14 outside the screw 13, the pressure plate 14 is moved away from the top of the U-shaped plate 9. Through the action of the I-shaped shaft 11, the ball block 12 can rotate on one side of the outer bracket 2 10, thereby releasing the compression and fastening of the U-shaped plate 9. After the operation, the sleeve 5 and the outer support 6 can rotate through the action of the connector 7, so that the arc-shaped cover 3 can be moved away from the end position of the shell 1, thus exposing both ends of the hollow fiber membrane 2 to the outside. This allows the hollow fiber membrane 2 to be removed from the inside of the shell 1. This structure is simple and easy to operate, effectively improving the operation of personnel. A rotating block 16 is fixedly installed on the outside of the pressure plate 14. The rotating block 16 is ring-shaped. By setting the rotating block 16, it is easy for personnel to rotate the pressure plate 14. An annular groove 17 is opened at the top of the shell 1. A sealing gasket 18 is inserted into the annular groove 17. The top of the sealing gasket 18 protrudes from the top of the shell 1. In the case of the annular groove 17 and the sealing gasket 18, when the arc-shaped cover 3 is closed on the top of the housing 1, the sealing gasket 18 can be squeezed, thereby further improving the sealing performance between the housing 1 and the arc-shaped cover 3. The sleeve 5 is tightly attached to the outer side of the outer bracket 6, and the ball block 12 is tightly attached to the outer side of the outer bracket 10, so that the arc-shaped cover 3 and the ball block 12 can rotate without their positions sagging due to gravity, so that personnel can push them later. The thread connecting the screw 13 and the pressure plate 14 is a fine thread, which has self-locking properties, thereby improving the stability of the connection.
[0022] like Figure 2 and Figure 4As shown, the connector 7 includes a shaft 19 that passes through the sleeve 5 and the outer bracket 6. A front baffle 20 is fixedly mounted at one end of the shaft 19, and a rear baffle 21 abuts against the other end. A threaded rod 22 is fixedly mounted on the outer side of the rear baffle 21 and inserted into a threaded hole 23 located at the end of the shaft 19. Both the front baffle 20 and the rear baffle 21 have internal hexagonal grooves on their outer sides. Both 21 abut against the outer side of the sleeve plate 5. The shaft 19 can rotate inside the sleeve plate 5 and the outer bracket 6. By providing the connecting piece 7, the rotation connection between the sleeve plate 5 and the outer bracket 6 can be restricted. When the personnel rotate the rear baffle 21, the threaded rod 22 can disengage from the inside of the threaded hole 23. Thus, the shaft 19 can be pulled out from the sleeve plate 5 and the outer bracket 6, and the sleeve plate 5 can be disassembled on the outside of the outer bracket 6 to facilitate the cleaning of the entire structure.
[0023] This utility model provides an antibacterial hollow fiber membrane filtration device, the specific working principle of which is as follows:
[0024] During use, the operator holds the outside of the rotating block 16 and rotates the pressure plate 14, causing the pressure plate 14 to rotate and rise outside the screw 13, thus disengaging the pressure plate 14 from the top of the U-shaped plate 9. Then, the screw 13 is pushed away from the arc-shaped cover 3. Under the action of the I-shaped shaft 11, the ball block 12 rotates on one side of the outer support 10, thereby releasing the tight connection between the shell 1 and the arc-shaped cover 3. Then, the arc-shaped cover 3 can be pushed upwards. Under the action of the connecting piece 7, the sleeve 5 rotates outside the outer support 6, thus exposing both ends of the hollow fiber membrane 2 to the outside. This allows the hollow fiber membrane 2 to be removed from the inside of the shell 1. When the operator rotates the rear baffle 21, the threaded rod 22 can disengage from the inside of the threaded hole 23, thereby pulling the shaft 19 out of the sleeve 5 and the outer support 6. Thus, the sleeve 5 can be disassembled on the outside of the outer support 6 for easy cleaning of the entire structure.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
