[0024] In order to make the technical scheme of the present application better understood by those skilled in the art, the present application will be further described in detail in combination with the drawings.

[0025] The present application provides a kind of Figures 1-5The ceramic membrane filter shown includes a filter tank 1, which serves as the main structure of the entire filter, providing installation space and protection for internal components such as membrane tubes 7, support plates 5, and positioning plates 6. Its solid shell can withstand certain pressure, ensuring that the filtration process takes place in a closed and stable environment, preventing liquid leakage and the entry of external impurities. The top of the filter tank 1 is provided with a tank cover 2, and a plurality of evenly distributed membrane tubes 7 are vertically arranged inside the filter tank 1. The membrane tubes 7, as the core filtering component, are evenly distributed inside the filter tank 1, and their porous structure can filter liquids according to pore size, achieving different precision filtration from microfiltration to nanofiltration, effectively removing large molecular organic matter, suspended solids, bacteria, and other impurities in the liquid. A plurality of conduits 4 are transversely inserted into one side of the tank cover 2, and a plurality of connecting heads 42 are arranged below the tail end of each conduit 4. A plurality of water outlets 41 are formed at the bottom of the tail end of each conduit 4, and the upper end of each connecting head 42 is threadedly connected to the inner wall of the corresponding water outlet 41. The lower end of the connecting head 42 is coupled to the upper end of the corresponding membrane tube 7. By coupling the connecting head 42 at the tail end of the conduit 4, it ensures that the liquid can accurately flow into the membrane tube 7 for filtration. The membrane tube 7 is vertically inserted into the holes of the support plate 5 and the positioning plate 6, maintaining a stable filtration position and improving the uniformity and efficiency of filtration.

[0026] A positioning plate 6 is arranged inside the lower part of the filter tank 1, and a support plate 5 is arranged at the top of the filter tank 1 between the bottom of the tank cover 2. The support plate 5 and the positioning plate 6 correspond to each other, and both the support plate 5 and the positioning plate 6 are vertically provided with a plurality of holes. The number of membrane tubes 7 corresponds to the number of holes.

[0027] Furthermore, in the above technical solution, the hole diameter of the support plate 5 at the upper end corresponds to the diameter of the membrane tube 7, the hole diameter of the support plate 5 is smaller than the lower end diameter of the membrane tube 7, the hole diameter of the positioning plate 6 corresponds to the diameter of the membrane tube 7, and the membrane tube 7 is vertically inserted into the corresponding holes of the support plate 5 and the positioning plate 6.

[0028] Furthermore, in the above technical solution, the support plate 5 is close to the edge, and a plurality of insertion holes 51 are formed. A plurality of insertion rods 8 are fixedly installed on the inner wall of the filter tank 1, the insertion rods 8 are L-shaped structures, and the insertion holes 51 of the edge of the support plate 5 are sleeved on the upper ends of the corresponding insertion rods 8.

[0029] Further, in the above technical solution, the filter tank 1 is divided into an upper chamber 11 and a lower chamber 12, the membrane tube 7 and the support plate 5 are located in the upper chamber 11 of the filter tank 1, the outlet of the membrane tube 7 is located in the lower chamber 12 of the filter tank 1, and the inside of the lower chamber 12 is a secondary filtering chamber. The design of dividing the filter tank 1 into the upper chamber 11 and the lower chamber 12 divides the filtering process into two stages, the upper chamber 11 performs preliminary filtering, and the lower chamber 12 serves as a secondary filtering chamber, thereby further improving the filtering effect and adapting to application scenarios with different impurity contents and water quality requirements.

[0030] Further, in the above technical solution, the positioning plate 6 is placed on the top of the filter tank 1, the tank cover 2 is capped above the positioning plate 6, the edge portion of the tank cover 2 is connected to the top edge portion of the filter tank 1 through bolts, and the upper and lower edge portions of the positioning plate 6 are connected to the top of the filter tank 1 and the bottom of the tank cover 2 through sealing gaskets. The tank cover 2 is installed on the top of the filter tank 1 and plays a sealing and protective role for the internal structure. The sealing performance of the filter tank 1 is ensured by connecting the edge portion of the tank cover 2 to the top edge portion of the filter tank 1 through bolts and installing sealing gaskets on the upper and lower edge portions in contact with the positioning plate 6, thereby preventing liquid leakage from the top.

[0031] Further, in the above technical solution, a plurality of openings 21 are formed in one side of the tank cover 2, the tail ends of the plurality of conduits 4 pass through corresponding openings 21 and are located below the inside of the tank cover 2, a partition piece 3 is arranged on the outside of one side of the tank cover 2, and sealing rings 31 are installed at the connection positions of the partition piece 3 and the conduits 4. The plurality of openings 21 formed in the tank cover 2 provide channels for the insertion of the conduits 4, so that liquid can be smoothly introduced into the inside of the filter tank 1, and the installation of the conduits 4 facilitates the input operation and flow control of liquid.

[0032] The working process of the ceramic membrane filter in use is as follows:

[0033] The design of the plurality of conduits 4 and the water outlet 41 can uniformly distribute liquid, so that each membrane tube 7 can obtain a relatively balanced flow, and the filtering effect is not affected by excessive or insufficient flow of some membrane tubes 7. The connection head 42 is threadedly connected to the inner wall of the water outlet 41, which facilitates the connection and disconnection of the membrane tube 7 and ensures the tightness of the connection to prevent liquid leakage. The partition piece 3 arranged on the outside of one side of the tank cover 2 and the sealing rings 31 installed at the connection positions of the partition piece 3 and the conduits 4 further enhance the sealing performance between the conduits 4 and the tank cover 2 to prevent liquid leakage from the connection positions. This structural design ensures the sealing performance and safety of liquid during the input process and avoids the adverse effects of liquid leakage on the environment and equipment.

[0034] The liquid to be filtered is delivered into the filter tank 1 through the conduits 4. Since the tank cover 2 is provided with a plurality of conduits 4 on one side, and each conduit 4 is provided with a plurality of water outlets 41 at the bottom of the tail end, the liquid can uniformly pass through each water outlet 41 and flow into the corresponding membrane tube 7 through the connecting head 42. By controlling the valves and other devices on the conduits, the flow rate and flow direction of the liquid can be easily controlled, ensuring that the liquid can be evenly distributed to each membrane tube and ensuring the smoothness of the filtration process. After the liquid enters the membrane tube 7, it begins to be filtered for the first time under the action of pressure. The membrane tube 7 has a porous structure with a specific pore size, and small molecular substances, solvents and part of the ions in the liquid can pass through the micropores of the membrane tube to become the filtrate after the preliminary filtration, while macromolecular substances, suspended matter, colloids and other larger impurities are intercepted by the membrane tube and cannot pass through the membrane pores, thereby realizing the preliminary separation of the liquid and the impurities. The filtrate after the preliminary filtration flows into the lower chamber 12 of the filter tank 1 through the outlet of the membrane tube 7.

[0035] The preliminary filtrate entering the lower chamber 12 is further filtered in this secondary filtration chamber. Different filter materials or structures can be provided inside the lower chamber 12 as needed to re-intercept and remove the small impurities that may remain in the filtrate, further improving the purity and quality of the filtrate and meeting the application scenarios that have strict requirements on water quality. The qualified filtrate after the secondary filtration is discharged from the outlet of the lower chamber 12 of the filter tank 1 and can be used for subsequent production or use. The impurities intercepted by the membrane tube 7 are left in the membrane tube 7 or the upper chamber 11, and when accumulated to a certain extent, the membrane tube 7 needs to be cleaned or replaced to ensure the continuous and efficient operation of the ceramic membrane filter.

[0036] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above figures and description are illustrative in nature and should not be construed as limiting the scope of protection claimed by the present application.
