Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a filter with a membrane stack structure. Background Technology

[0002] A filter is a device used to remove impurities from gases or liquids. It is usually made of porous or fibrous materials. Its main function is to protect downstream equipment from blockage or wear and ensure the normal operation of the system. For example, in a pipeline system, a filter can remove solid impurities from the fluid, making the fluid purer and thus protecting equipment such as pumps and valves.

[0003] Modern membrane stack filters typically consist of multiple membrane sheets, usually made of materials such as polyester, polyamide, and polycarbonate. These membrane sheets have a microporous filtration function and are fixed inside the membrane housing through multiple storage holes to form a membrane stack. Through microporous filtration, they filter out impurities, particulate matter, organic matter, and other substances from the water. However, regardless of the type of filter, there is an optimal service life, and the filter cartridge needs to be replaced to ensure the filtration effect. Therefore, if replacement is inconvenient during operation, it can also cause inconvenience to the staff. Utility Model Content

[0004] The purpose of this utility model is to provide a filter with a membrane stack structure to solve the problem mentioned in the background art that no matter what kind of filter it is, there is an optimal service life and the filter element needs to be replaced to ensure the filtration effect. Therefore, if the replacement is inconvenient during operation, it will also cause inconvenience to the staff.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter with a membrane stack structure, comprising a filter housing, a membrane stack housing, and a membrane stack body. Guide blocks are fixed on both sides of the inner wall of the filter housing, and arc-shaped grooves are formed on the sides of the guide blocks. A groove is formed in the guide blocks, and a ball is embedded in the groove. A threaded groove is fixed at the upper end of the inner wall of the filter housing, and a threaded connector is connected to the threaded groove. The top of the threaded connector is connected to the water inlet. A first sealing ring is fixed at the upper part of the inner wall of the filter housing. A slot is formed in the top of the membrane stack housing, and an insert is inserted into the slot. A second sealing ring is fixed on the inner wall of the slot, and a filter plate is fixed on the top of the insert.

[0006] As a further technical solution of this utility model, a threaded connection is formed between the threaded connector and the threaded groove, and the first sealing ring is arranged below the threaded connector.

[0007] As a further technical solution of this utility model, the guide blocks are symmetrically distributed about the central axis of the filter housing, and the grooves are symmetrically distributed about the central axis of the guide blocks.

[0008] As a further technical solution of this utility model, positioning holes are provided on both sides of the filter plate, and positioning posts are fixed on both sides of the top of the membrane stack shell, with locking nuts connected to the outside of the positioning posts.

[0009] As a further technical solution of this utility model, the positioning posts are symmetrically distributed about the central axis of the membrane stack shell, and the positioning posts and the locking nut form a threaded connection.

[0010] As a further technical solution of this utility model, the inner diameter of the positioning hole is larger than the outer diameter of the positioning post, and a filter screen is provided in the middle position of the filter plate.

[0011] As a further technical solution of this utility model, a positioning seat is fixed at the lower part of the inside of the filter housing, a groove is formed in the positioning seat, the membrane stack housing is placed in the groove, a water inlet is opened in the bottom of the filter housing, and a water outlet is installed at the bottom of the filter housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the filter with this membrane stack structure not only improves the convenience of replacement, but also improves the connection and assembly capability and the downward flow guiding capability of the filter.

[0014] 1. A positioning seat is fixed at the lower part of the inner wall of the filter housing, and guide blocks are fixed on both sides of the inner wall of the filter housing. After the guide block is opened with an arc groove, the groove is opened in the guide block, and the ball is embedded in the groove. Therefore, when assembling and removing the membrane stack housing, the two sides of the membrane stack housing are assembled along the arc of the arc groove. This process is guided by the groove and the ball. The bottom of the membrane stack housing can be accommodated in the groove. The membrane stack body is arranged in the membrane stack housing, and the membrane stack housing is arranged in the filter housing. This facilitates the replacement of the membrane stack housing in the future and improves the overall convenience.

[0015] 2. By fixing the positioning post to the top of the membrane stack shell, and after opening a slot inside the top of the membrane stack shell, a second sealing ring is used for sealing. Then, positioning holes are opened on both sides of the filter plate. Therefore, during assembly, the positioning post can pass through the internal guide of the positioning hole, and then the position is locked with a locking nut, which facilitates the assembly of the filter plate. At the same time, a threaded groove is fixed on the inner wall of the filter shell. This threaded groove is connected and assembled with a threaded connector, which allows for the assembly of the inlet, making the overall assembly more convenient.

[0016] 3. By installing and fixing the positioning seat in the lower position inside the filter housing, and opening the first filter screen inside the positioning seat, the first filter screen is used for water flow. On both sides of the inner wall of the filter housing, below the positioning seat, the ramp blocks are fixed. The inclined design of the ramp blocks can guide the water when it flows out at the position of the first filter screen, thereby improving the overall downward flow guiding capacity during operation.
