[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1-Figure 4As shown, in this embodiment, a BPM hollow fiber membrane installation structure that is easy to install includes: an installation mechanism 1, the installation mechanism 1 includes an installation shell 11, a top cover 12 is provided at one end of the installation shell 11, a hollow fiber membrane bundle 13 is provided inside the installation shell 11, and installation covers 14 are provided at both ends of the hollow fiber membrane bundle 13. Both sides of the top cover 12 away from one end of the installation shell 11 are fixedly connected with handles 31, one end of the installation shell 11 is connected to the top cover 12, and the two ends of the hollow fiber membrane bundle 13 are respectively connected to the opposite sides of the two installation covers 14, and the two ends of the hollow fiber membrane bundle 13 are connected to the opposite sides of the two installation covers 14. Four positioning blocks 15 are arranged in an annular array on the outside of each mounting cover 14. A water guide port 16 is arranged on the side of the two mounting covers 14 away from the hollow fiber membrane bundle 13. Four positioning grooves 17 are arranged in an annular array on the inner wall of the mounting shell 11. The four positioning blocks 15 are fixedly connected to the outside of the mounting cover 14 on one side close to the mounting cover 14. The outer surface of the positioning block 15 is slidably connected to the inner wall of the positioning groove 17. One end of the water guide port 16 is docked in the slot opened on the side of the mounting cover 14 away from the hollow fiber membrane bundle 13. The outside of the mounting shell 11 is close to the top cover 12. A plurality of positioning holes 18 are arranged in a circular array at one end of the top cover 12, a plurality of mounting shells 11 are arranged in a circular array on the outside of the top cover 12, a plurality of mounting shells 11 are arranged on a side away from the top cover 12 with a plate 110, a movable rod 111 is arranged inside the mounting shell 11, a side of the mounting block 19 close to the top cover 12 is fixedly connected to the outside of the top cover 12, a side of the mounting block 19 away from the top cover 12 is in contact with a side of the plate 110 close to the mounting block 19, one end of the movable rod 111 passes through the mounting block 19 and is movably connected to the inside of the plate 110, and a plurality of movable rods 111 are arranged on the inside of the top cover 12 with a plurality of movable rods 111. A return spring 112 is provided on the outside, and a clamping block 113 is provided on one end of each movable rod 111 away from the block 110. The other end of the movable rod 111 passes through the inner circle of the return spring 112 and is fixedly connected to one end of the clamping block 113. The other end of the clamping block 113 passes through the clamping groove opened on the outside of the top cover 12 and is clamped inside the positioning hole 18. One end of the return spring 112 is fixedly connected to the inner wall of the mounting block 19 close to the block 110, and the other end of the return spring 112 is fixedly connected to one end of the clamping block 113 close to the movable rod 111. A clamping mechanism 2 is provided inside the top cover 12.

[0024] In this embodiment, when the staff needs to install the hollow fiber membrane bundle 13 in the installation shell 11 for use, the hollow fiber membrane bundle 13 and the installation cover 14 are first inserted into the installation shell 11, and then the positioning block 15 will slide in the positioning groove 17. The positioning block 15 and the positioning groove 17 can achieve the positioning and installation effect of the hollow fiber membrane bundle and the installation cover 14 to prevent them from shaking in the installation shell 11. Therefore, the staff moves the blocks 110 on the outside of the top cover 12. When the blocks 110 are moved, the blocks 110 will be squeezed and contacted with the installation block 19, and then the pulling force will pull the movable rod 111 and the block 113 toward the blocks. The top cover 12 and the mounting shell 11 are fixed together by the top cover 12 and the mounting shell 11 are prevented from using special tools and equipment for installation, which saves the time and energy of the staff and reduces the error rate of installation.

[0025] like Figure 2 and Figure 4 As shown, the clamping mechanism 2 includes a pressing plate 21, a through hole 22 is opened in the center of the pressing plate 21, a plurality of springs 23 are fixedly connected to one side of the pressing plate 21, and the ends of the plurality of springs 23 away from the top cover 12 are fixedly connected to the ends of the inner wall of the top cover 12 away from the mounting cover 14.

[0026] In this embodiment, the water inlet 16 near one end of the top cover 12 will pass through the through hole 22 and the slot opened on the side of the top cover 12 away from the mounting shell 11, thereby ensuring that the water inlet 16 of the top cover 12 can be exposed to the outside world and connected to other equipment after the installation is completed. At the same time, when the top cover 12 is docked with the mounting shell 11, the pressure plate 21 provided inside the top cover 12 will squeeze the mounting cover 14 near one end of the top cover 12, and then the spring 23 will expand and contract when subjected to the squeezing force, thereby avoiding damage to the hollow fiber membrane bundle 13 and the mounting cover 14 due to excessive compression force, thereby ensuring that the hollow fiber membrane bundle 13 and the mounting cover 14 will not move in the mounting shell 11.

[0027] The utility model provides a BPM hollow fiber membrane installation structure that is easy to install, and the specific working principle is as follows:

[0028] When the staff needs to install the hollow fiber membrane bundle 13, they first need to insert the hollow fiber membrane bundle 13 and the mounting cover 14 into the mounting shell 11. During this process, the positioning block 15 will slide in the positioning groove 17 to ensure that the hollow fiber membrane bundle 13 and the mounting cover 14 can be accurately installed in the mounting shell 11. Next, the staff needs to move the lever 110 located on the outside of the top cover 12. When the lever 110 is moved, it will be squeezed and contacted with the mounting block 19. This squeezing and contacting process will cause the pulling force to pull the movable rod 111 and the block 113 toward the direction of the lever 110, so that the block 113 will move into the empty compartment recessed into the mounting block 19. During this movement, the return spring 112 will be squeezed by the block 113, thereby causing expansion and contraction deformation, and the work Personnel can dock the top cover 12 at one end of the mounting shell 11, and then by lowering the lever block 110, the return spring 112 will lose its extrusion force, and then release its stored elastic force, pushing the block 113 through the slot opened in the top cover 12, and finally clamped in the positioning slot 17, so that the top cover 12 and the mounting shell 11 are fixed. In the process of docking the top cover 12 with the mounting shell 11, the pressure plate 21 provided inside the top cover 12 will squeeze the mounting cover 14 near one end of the top cover 12. This squeezing process is to prevent the hollow fiber membrane bundle 13 and the mounting cover 14 from shifting during the installation process. At the same time, the spring 23 will undergo telescopic deformation when subjected to the extrusion force. This is to enable the spring 23 to absorb part of the force through deformation when the extrusion force is too large, thereby avoiding damage to the hollow fiber membrane bundle 13 and the mounting cover 14.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
