To solve these problems, this utility model provides a ceramic membrane filtration device that facilitates switching between different filtration levels. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ceramic membrane filtration device that facilitates switching between different filtration levels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ceramic membrane filtration device that facilitates switching between different filtration levels includes a filter cartridge, a filter cover, three ceramic membrane filter elements, and a fixing assembly, wherein the filter cover is detachably mounted on the upper end of the filter cartridge.

[0007] The filter cartridge is internally fixedly connected to three partition plates, which divide the filter cartridge into three independent areas. The lower end of the filter cartridge has three outlet slots. The lower ends of the three ceramic membrane filter elements are provided with outlet pipes that are adapted to the outlet slots. The outlet pipes and outlet slots are sealed and inserted together.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 A ceramic membrane filtration device that facilitates switching between different filtration levels includes a filter cartridge 1, a filter cover 2, three ceramic membrane filter elements 3, and a fixing assembly. The filter cover 2 is detachably installed on the upper end of the filter cartridge 1.

[0024] The filter cartridge 1 is internally fixedly connected to three partition plates 4, which divide the filter cartridge 1 into three independent areas. The lower end of the filter cartridge 1 is provided with three outlet grooves 5. The lower end of the three ceramic membrane filter elements 3 is provided with outlet pipes 6 that are adapted to the outlet grooves 5. The outlet pipes 6 and the outlet grooves 5 are sealed and inserted. The upper end of the filter cover 2 is fixedly connected to a flow divider assembly, which includes a first flow divider pipe 7, a second flow divider pipe 8 and a third flow divider pipe 9. A first three-way valve 10 is provided between the second flow divider pipe 8 and the third flow divider pipe 9.

[0025] In this utility model, the diversion assembly also includes a second three-way valve 11 and an inlet pipe 12. The two ends of the second three-way valve 11 are connected to the first diversion pipe 7 and the inlet pipe 12, respectively. As a key control component, the second three-way valve 11 can accurately adjust the flow direction of the fluid. The inlet pipe 12 serves as the initial channel for the fluid to enter the device. The two work together to provide a basic guarantee for the entire diversion process. The outlet end of the second three-way valve 11 is fixedly connected to a connecting pipe 13. The connecting pipe 13 plays a transition and guiding role, ensuring that the fluid can flow out of the second three-way valve 11 stably. The other end of the connecting pipe 13 is fixedly connected to the inlet end of the first three-way valve 10.

[0026] The fixing assembly includes a first fixing ring 14 and a second fixing ring 15, which are hinged together. The first fixing ring 14 and the second fixing ring 15 cooperate with each other to form the main structure for fixing the filter cartridge 1 and the filter cover 2, facilitating the installation and removal of the filter cartridge 1 and the filter cover 2. Connecting blocks 16 are fixedly connected to the front of both the first fixing ring 14 and the second fixing ring 15. One of the connecting blocks 16 has a threaded hole on its surface, and the other connecting block 16 has a through hole on its surface. A fixing bolt 17 that matches the threaded hole is inserted into the through hole. The fixing bolt 17 generates a strong tightening force through the threaded engagement with the threaded hole, ensuring that the first fixing ring 14 and the second fixing ring 15 are tightly fixed together, thereby ensuring a stable connection between the filter cartridge 1 and the filter cover 2.

[0027] A sealing connection plate 18 is fixedly connected to one end of the filter cartridge 1 and the filter cover 2. The sealing connection plate 18 can increase the contact area between the filter cartridge 1 and the filter cover 2 and improve the sealing effect. The first fixing ring 14 and the second fixing ring 15 are both provided with a connecting groove 19 that matches the sealing connection plate 18. The connecting groove 19 fits tightly with the sealing connection plate 18, which enhances the sealing of the connection between the filter cartridge 1 and the filter cover 2 and prevents fluid leakage during the filtration process.

[0028] The upper part of the filter cover 2 has several positioning grooves. The upper ends of the three ceramic membrane filter elements 3 are all fixedly connected with positioning blocks 20 that are compatible with the positioning grooves. The cooperation between the positioning blocks 20 and the positioning grooves allows the ceramic membrane filter elements 3 to be quickly positioned during installation and remain stable during filtration without shaking or shifting. The upper part of the filter cover 2 has a sealing groove 21 that is compatible with the three partition plates 4. The sealing groove 21 can fit tightly with the three partition plates 4 to form a good sealing effect, preventing fluid leakage between different filtration areas and ensuring that each filtration area can perform filtration independently and effectively.

[0029] Three outlet valve pipes 22 are fixedly connected to the lower end of the filter cartridge 1. The outlet valve pipes 22 serve as the discharge channels for the filtered fluid. By controlling the opening and closing of the valves, the discharge volume and discharge time of the fluid can be flexibly adjusted. The outlet valve pipes 22 are connected to the outlet groove 5. Three support bases 23 are fixedly connected to the lower end of the filter cartridge 1. The three support bases 23 are evenly distributed at the lower end of the filter cartridge 1. The support bases 23 provide stable support for the entire filtration device, ensuring that the device will not tip over or shake during operation.

[0030] When using this utility model, firstly, the outlet pipes 6 of the three ceramic membrane filter elements 3 are respectively sealed and inserted into the three outlet grooves 5 opened at the lower end of the filter cylinder 1, so that the ceramic membrane filter elements 3 are installed in the three independent areas divided by the three partition plates 4 inside the filter cylinder 1. At the same time, the positioning block 20 at the upper end of the ceramic membrane filter element 3 is installed in correspondence with the positioning groove opened at the upper end of the filter cover 2, and the sealing groove 21 at the upper end of the filter cover 2 is adapted to the three partition plates 4 to achieve a seal. Then, the filter cover 2 is installed at the upper end of the filter cylinder 1, and then fixed using the fixing components. The first fixing ring 14 and the second fixing ring 15 are opened by hinge and fitted onto the sealing connecting plate 18 at the opposite end of the filter cylinder 1 and the filter cover 2, so that the sealing connecting plate 18 is embedded in the connecting groove 19 opened inside the first fixing ring 14 and the second fixing ring 15. Then, the fixing bolt 17 is passed through the through hole on one connecting block 16 and screwed into the threaded hole on the surface of another connecting block 16 to complete the fixed connection of the filter cylinder 1 and the filter cover 2.

[0031] After installation, the filtration operation is performed. The fluid enters from the inlet pipe 12 and passes through the second three-way valve 11. The second three-way valve 11 can control the fluid to enter the first diversion pipe 7 or the connecting pipe 13. When the fluid enters the connecting pipe 13, it reaches the first three-way valve 10. The first three-way valve 10 can control the fluid to enter the second diversion pipe 8 or the third diversion pipe 9. By controlling the first three-way valve 10 and the second three-way valve 11, the fluid can be switched between the corresponding flow paths of different ceramic membrane filter elements 3, thereby switching between different filtration levels. The filtered fluid flows out from the outlet tank 5 through the outlet valve pipe 22. The three support bases 23 evenly distributed at the lower end of the filter cylinder 1 provide support for the device.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
