Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration membrane modules, in particular to an ultrafiltration membrane module provided with an anti-blocking structure. Background Technique

[0002] A tubular ultrafiltration membrane module is a module that assembles an ultrafiltration membrane in a tubular form in a specific device. It uses the pressure difference as the driving force and through physical separation, enables small molecule substances to pass through the membrane while retaining macromolecule substances, thereby achieving the purpose of purification or separation.

[0003] Currently, in order to prevent impurities in water from scratching the membrane filaments in the tubular ultrafiltration membrane module, a filter screen is set at the water inlet end to first filter larger particle impurities. However, once the filter screen is blocked, it will affect the normal use of the tubular ultrafiltration membrane module;

[0004] The existing publicly disclosed technical solution, with the publication number of CN220633764U, discloses a tubular ultrafiltration membrane module with a convenient cleaning structure, including a water inlet pipe, a housing, and a water outlet pipe. A cleaning mechanism is provided in the water inlet pipe. The cleaning mechanism includes a round wheel, and a plurality of scraping plates are evenly and fixedly installed on the outer surface of the round wheel. A circular cover plate is fixedly installed on the inner wall surface of the water inlet pipe at the lower end of the scraping plate. Circular arc-shaped leakage holes are formed on the outer surface of the circular cover plate, and a collection mechanism is provided at the lower end of the circular cover plate. By driving the scraping plates to clean the filter substances attached to the surface of the filter plate after the round wheel rotates, the blockage of the surface of the filter plate is prevented, and the filtration speed of the stock solution is accelerated.

[0005] When the above technical solution is actually implemented, in addition to setting a cleaning mechanism to clean the filter plate, a collection mechanism is also set to collect the filter substances. However, the filter plate and the internal membrane filaments for filtration are not convenient to replace. Since both the membrane filaments and the filter plate have a certain service life, once the membrane filaments and the filter plate fail, the entire tubular ultrafiltration membrane module needs to be replaced, which requires a relatively high usage cost. Summary of the Invention

[0006] The purpose of the utility model is to provide an ultrafiltration membrane module provided with an anti-blocking structure, which can replace the membrane filaments and the filter plate, while the other supporting components inside can be reused repeatedly, effectively reducing the usage cost, so as to solve the problems raised in the above background technique.

A membrane filament is movably arranged between the filter assembly and the fixed head, and the tube body communicates with the fixed head and the movable head. A water outlet is fixedly arranged on one side of the fixed head, and a water inlet is fixedly arranged on one side of the movable head;

[0008] The filter assembly includes a filter plate slidably installed inside the tube body;

A membrane filament 9 is movably arranged between the filter assembly 8 and the fixed head 2, and the tube body 1 communicates with the fixed head 2 and the movable head 4. A water outlet 3 is fixedly arranged on one side of the fixed head 2, and a water inlet 6 is fixedly arranged on one side of the movable head 4;

[0029] The filter assembly 8 includes a filter plate 801 slidably installed inside the tube body 1;

[0030] The cleaning assembly 5 includes a rotating blade 501 movably installed on the filter plate 801 and a scraping plate 507 that fits tightly with the filter plate 801.

[0031] By adopting the above technical solution, after unscrewing the movable head 4, the cleaning assembly 5 inside the movable head 4 can be removed, and the filter assembly 8 can be disassembled. The tubular membrane filament 9 inside can be directly taken out. After the membrane filament 9 and the filter assembly 8 are disassembled and replaced, the remaining cleaning assembly 5, tube body 1, movable head 4 and other components can be repeatedly used after cleaning, thereby reducing the use cost.

[0032] Specifically, as Figure 2 and Figure 3 shown, the filter assembly 8 further includes mounting blocks 802 installed around the filter plate 801, and mounting slots 803 adapted to the mounting blocks 802 are provided at the connection between the mounting blocks 802 and the tube body 1. A fixing member 804 is fixedly arranged inside the filter plate 801, and a second mounting hole 806 is provided in the middle of the fixing member 804. A limiting slot 805 is provided on the inner wall of the second mounting hole 806.

[0033] By adopting the above technical solution, raw water enters the tube body 1 from the water inlet 6 on the movable head 4, and the filter plate 801 can be installed inside the tube body 1 through the mounting blocks 802 and the mounting slots 803. The filter plate 801 is in close contact with the membrane filament 9. When the water filtered by the filter plate 801 can enter the membrane filament 9, and after being filtered by the membrane filament 9, it is discharged outward through the water outlet 3 on the fixed head 2.

[0034] Specifically, as Figure 4As shown in the figure, the cleaning component 5 further includes a sleeve 504 fixed inside the rotating blade 501. A support rod 505 is connected inside the sleeve 504 through a bearing. The support rod 505 passes through the inside of the second mounting hole 806. A limit block 506 adapted to the limit card slot 805 is provided at the connection between the support rod 505 and the second mounting hole 806. A scraping plate 507 is fixed on the surface of the sleeve 504. The top of the support rod 505 is connected to a pressing plate 503 through a spring. An expansion rod 502 passing through the inside of the support rod 505 is provided between the pressing plate 503 and the support rod 505. The expansion rod 502 is sleeved on the surface of the spring. A first mounting hole 7 is opened at the bottom of the movable head 4, and the pressing plate 503 passes through the inside of the first mounting hole 7.

[0035] By adopting the above technical solution, when the raw water enters the pipe body 1, it passes through the inclined rotating blade 501, which can push the sleeve 504 on the rotating blade 501 to rotate on the support rod 505. Thereby driving the scraping plate 507 on the sleeve 504 to rotate synchronously.

[0036] Working principle: During assembly, the membrane filaments 9 are inserted into the pipe body 1. Subsequently, the filter plate 801 can be installed inside the pipe body 1 through the installation block 802 and the installation card slot 803, and the filter plate 801 is closely attached to the membrane filaments 9. Then the cleaning component 5 is inserted into the middle of the filter plate 801. The limit block 506 on the support rod 505 is inserted into the limit card slot 805, and the support rod 505 is synchronously inserted into the second mounting hole 806 to limit the support rod 505. Then the movable head 4 is sleeved outside the pipe body 1. The pressing plate 503 is aligned with the position of the first mounting hole 7. When the movable head 4 is rotated, it gradually approaches the pressing plate 503, and the pressing plate 503 can compress the internal spring and drive the expansion rod 502 to insert into the support rod 505 until the pressing plate 503 is closely attached to the support rod 505 to further limit the support rod 505. At the same time, the support rod 505 can also support the filter plate 801 and the membrane filaments 9. The raw water enters the pipe body 1 from the water inlet 6 on the movable head 4, which can push the sleeve 504 on the rotating blade 501 to rotate on the support rod 505. Thereby driving the scraping plate 507 on the sleeve 504 to rotate synchronously. A brush is provided on one side of the scraping plate 507 close to the filter plate 801, so as to realize cleaning the filter plate 801 when the scraping plate 507 rotates. The water filtered by the filter plate 801 can enter the membrane filaments 9 and is discharged outward through the water outlet 3 on the fixed head 2 after being filtered by the membrane filaments 9.
