Description

Technical Field

[0001] The utility model relates to the technical field of hollow fiber membrane components, in particular to a hollow fiber membrane component. Background Art

[0002] The hollow fiber membrane assembly is an asymmetric self-supporting filter membrane that can be backwashed to maximize the benefits of cross-flow filtration. The geometric configuration of the hollow fiber maximizes the membrane surface area in the smallest space. It is divided into two types of membranes: internal pressure and external pressure, including microfiltration membrane assemblies, ultrafiltration membrane assemblies, and nanofiltration membrane assemblies.

[0003] Existing public patent: CN202221905260.X A hollow fiber membrane assembly uses a clamping block, a spring, a connecting block and a hollow fiber membrane bundle in coordination with each other, so that the connecting block and the hollow fiber membrane bundle can be replaced separately, and the disassembly and replacement are simple and convenient, saving resources.

[0004] However, in this comparative example, the lower side of the hollow fiber membrane bundle is fixed by a threaded rod, and removing the upper end fixation of the hollow fiber membrane bundle also requires first removing the threaded rod and then removing the top cover. Multiple bolts need to be removed and installed during the entire disassembly and installation process. The disassembly process is relatively cumbersome, and when the hollow fiber membrane bundle needs to be replaced, all hollow fiber membrane bundles cannot be disassembled at the same time, which makes the disassembly and installation efficiency slow, thereby reducing the practicability of the hollow fiber membrane bundle.

[0075] Furthermore, a plurality of fixing springs 18 are fixedly connected to the adjacent outer surfaces of the two second fixing blocks 16;

[0076] The fixing spring 18 is slidably mounted outside the second positioning column 19;

[0083] Among them, a plurality of hollow fiber membrane bundles 8 are fixedly arranged between the upper surface of the positioning block 7 and the lower surface of the limiting sliding block 5 .

[0084] Furthermore, the hollow fiber membrane bundle 8 is an existing technology in a hollow fiber membrane assembly according to the existing public patent: CN202221905260.X, which will not be elaborated here.

[0085] Furthermore, when in use, the first handle 10 is first pulled out to move the first handle 10 upward. In this process, not only the support block 11, the sliding rod 13, the first fixing block 9 and the first positioning column 14 are driven to move upward, but also the support spring 12 is squeezed synchronously, so that the support spring 12 is squeezed and deformed. When the first positioning column 14 moves upward to the top of the mounting block 2, the plurality of limit sliders 5 are slid into the plurality of limit slide grooves 4, so that the rear side surface of the limit slider 5 contacts the rear side inner wall of the limit slide groove 4. At this time, the pulling of the first handle 10 is released, and the first positioning column 12 is pushed under the action of the released elastic force of the support spring 12. The positioning column 14, the sliding rod 13, the support block 11, and the first fixed block 9 move downward, thereby synchronously driving multiple first positioning columns 14 to move downward at the same time into the second positioning holes 21 on the multiple limit sliders 5. At this time, the first positioning column 14 fixes the limit slider 5, so that the limit slider 5 cannot move forward and be pulled out of the limit slide groove 4, thereby synchronously fixing the upper side of the hollow fiber membrane bundle 8. The fixation is convenient, and the upper sides of multiple hollow fiber membrane bundles 8 can be fixed at the same time. The fixation is quick, which saves manpower and increases the installation efficiency of the hollow fiber membrane assembly, thereby increasing the practicality of the hollow fiber membrane assembly.

[0086] Furthermore, when the lower side of the hollow fiber membrane bundle 8 needs to be installed, it is necessary to first pull the second handle 17 to drive the second fixing block 16 to move away from the installation block 2, and then synchronously drive the second positioning column 19 to move. During this process, the fixing spring 18 will be stretched. When the second positioning column 19 moves out of the positioning groove 6, the multiple positioning blocks 7 are slid into the multiple positioning grooves 6, and then the pulling of the second handle 17 is released. Under the action of the release elastic force of the fixing spring 18, the second fixing block 16 is synchronously driven to slide into the connection The second positioning columns 19 are used to fix the positioning blocks 7 so that the positioning blocks 7 cannot be pulled out of the positioning grooves 6 upwards, thereby simultaneously fixing the lower side of the hollow fiber membrane bundle 8, and the installation is quick. By pulling out the second handle 17, the lower sides of multiple hollow fiber membrane bundles 8 can be fixed at the same time, which saves manpower and increases the installation efficiency of the hollow fiber membrane assembly, thereby increasing the practicality of the hollow fiber membrane assembly.

[0087] Furthermore, when disassembly is required, according to the above principle, only the second handle 17 is pulled out to move the second positioning column 19 out of the first positioning hole 20, and then the positioning block 7 is pulled upward to complete the lower side disassembly, and then the first handle 10 is pulled out to move the first positioning column 14 out of the second positioning hole 21, and then the limiting slider 5 is pulled forward out of the limiting slide groove 4 to complete the disassembly. The disassembly is convenient and quick, and no tools are required for installation and disassembly, thereby increasing manpower savings while increasing the installation and disassembly efficiency of the hollow fiber membrane assembly, thereby increasing the practicality of the hollow fiber membrane assembly.

[0088] Furthermore, in this solution, when installing the hollow fiber membrane assembly, the limit slider 5 needs to be installed first, and then the positioning block 7 is installed.

[0089] Working principle: When the device is in use, the first handle 10 is first pulled to move the first handle 10 upward. In this process, not only the support block 11, the sliding rod 13, the first fixing block 9 and the first positioning column 14 are moved upward, but also the support spring 12 is squeezed synchronously, so that the support spring 12 is squeezed and deformed. When the first positioning column 14 moves upward to the top of the mounting block 2, the plurality of limit sliders 5 are slid into the plurality of limit slots 4, so that the rear side surface of the limit sliders 5 contacts the rear side inner wall of the limit slot 4. At this time, the pulling of the first handle 10 is released, and under the action of the release elastic force of the support spring 12 , pushing the first positioning column 14, the sliding rod 13, the supporting block 11, and the first fixing block 9 to move downward, thereby synchronously driving multiple first positioning columns 14 to move downward simultaneously into the second positioning holes 21 on the multiple limiting sliding blocks 5, and then the first positioning column 14 fixes the limiting sliding block 5 at this time, so that the limiting sliding block 5 cannot move forward and be pulled out of the limiting sliding groove 4, and then synchronously fixes the upper side of the hollow fiber membrane bundle 8, which is convenient to fix, and can fix the upper sides of multiple hollow fiber membrane bundles 8 at the same time, and is quick to fix, which saves manpower while increasing the installation efficiency of the hollow fiber membrane assembly, thereby increasing the practicality of the hollow fiber membrane assembly.

[0090] Furthermore, when the lower side of the hollow fiber membrane bundle 8 needs to be installed, it is necessary to first pull the second handle 17 to drive the second fixing block 16 to move away from the installation block 2, and then synchronously drive the second positioning column 19 to move. During this process, the fixing spring 18 will be stretched. When the second positioning column 19 moves out of the positioning groove 6, the multiple positioning blocks 7 are slid into the multiple positioning grooves 6, and then the pulling of the second handle 17 is released. Under the action of the release elastic force of the fixing spring 18, the second fixing block 16 is synchronously driven to slide into the connection The second positioning columns 19 are used to fix the positioning blocks 7 so that the positioning blocks 7 cannot be pulled out of the positioning grooves 6 upwards, thereby simultaneously fixing the lower side of the hollow fiber membrane bundle 8, and the installation is quick. By pulling out the second handle 17, the lower sides of multiple hollow fiber membrane bundles 8 can be fixed at the same time, which saves manpower and increases the installation efficiency of the hollow fiber membrane assembly, thereby increasing the practicality of the hollow fiber membrane assembly.

[0091] Furthermore, when disassembly is required, according to the above principle, only the second handle 17 is pulled out to move the second positioning column 19 out of the first positioning hole 20, and then the positioning block 7 is pulled upward to complete the lower side disassembly, and then the first handle 10 is pulled out to move the first positioning column 14 out of the second positioning hole 21, and then the limiting slider 5 is pulled forward out of the limiting slide groove 4 to complete the disassembly. The disassembly is convenient and quick, and no tools are required for installation and disassembly, thereby increasing manpower savings while increasing the installation and disassembly efficiency of the hollow fiber membrane assembly, thereby increasing the practicality of the hollow fiber membrane assembly.
