[0025] In order to make the technical personnel in the field better understand the technical scheme of the utility model, the utility model will be further introduced in detail below in combination with the drawings.

[0026] The utility model provides a kind of ceramic membrane convenient to clean as Figures 1-5 It is a kind of ceramic membrane convenient to clean, including ceramic membrane main body 1, the inside center and four quarters of ceramic membrane main body 1 are vertically through and are provided with pipe hole 12 in fan-shaped distribution, the pipe hole 12 in the center of ceramic membrane main body 1 is cylindrical, the pipe hole 12 in fan-shaped distribution of ceramic membrane main body 1 is triangular, the special shape of triangular pipe hole 12 and arc inner wall angle, when cleaning, can change the flow form of fluid, promote cleaning fluid to form turbulent flow, enhance the scouring force to pollutant.Simultaneously, this shape reduces cleaning dead angle, so that pollutant is difficult to adhere and remain, effectively improves the cleaning effect.Moreover, fan-shaped distribution makes pipe hole 12 layout reasonable, it is beneficial to the uniform distribution of cleaning fluid, ensure that each pipe hole 12 can be fully cleaned, the size of the pipe hole is not less than two centimeters, large size pipe hole 12 provides spacious passageway for cleaning tool and cleaning fluid, facilitates operation in it, and then can use larger diameter soft hair brush or high pressure flushing spray head to the pipe hole 12 inside and membrane tube 2 are cleaned comprehensively, avoid the problem that pollutant is difficult to touch due to narrow space;

[0027] A plurality of membrane tubes 2 are vertically inserted into each tube hole 12, each membrane tube 2 is uniformly distributed and does not contact each other, and the outer wall of each membrane tube 2 does not contact the inner wall of the tube hole 12. The membrane tube 2 is composed of two or more layers of different ceramic materials, one of which can focus on separation performance. By selecting ceramic materials with specific pore size and porosity, target substances can be accurately trapped, such as effectively filtering out small impurity particles, bacteria or viruses in water treatment. The other layer of material can focus on providing mechanical support. By using ceramic materials with high hardness and high strength, it ensures that the membrane tube will not break or deform when subjected to high pressure difference. This complementary design allows the membrane tube to have higher structural stability while ensuring good filtration effect, suitable for filtration work under various pressure conditions.

[0028] The upper end and the lower end of the ceramic membrane body 1 are provided with end covers 3, and the two end covers 3 are respectively buckled on the top end and the bottom end of the ceramic membrane body 1.

[0029] Further, in the above technical solution, the upper end and the lower end of the ceramic membrane body 1 are both laterally provided with threaded holes 11, and the two sides of the end cover 3 are both provided with bolts 32. The end cover 3 is fixedly connected with the end of the ceramic membrane body 1 through the bolts 32, thereby realizing reliable connection of the end cover 3 with the ceramic membrane body 1. This connection method is simple, easy to operate and stable. In the daily use of the ceramic membrane, it can effectively prevent the end cover 3 from accidentally falling off, ensure the sealing and stability of the internal structure of the ceramic membrane, and ensure the normal progress of the filtration process. When maintenance and cleaning are required, the bolt connection is convenient for the operator to quickly disassemble the end cover 3, providing a convenient channel for subsequent inspection, cleaning or replacement of the membrane tube 2 and the tube hole 12, greatly shortening the maintenance time and workload.

[0030] Further, in the above technical solution, the inner wall of the tube hole 12 of the ceramic membrane body 1 is arc-shaped, and each tube hole 12 has a ceramic membrane layer. The inner wall and the outer wall of each membrane tube 2 have ceramic membrane layers, and the ceramic membrane layers covering the inner wall of the tube hole 12 and the inner and outer walls of the membrane tube 2 play a key role in the filtration process, ensuring accurate separation of target substances. In the cleaning process, the hydrophilicity and surface activity of the ceramic membrane layer help the cleaning liquid to quickly wet and spread on the membrane surface, enhance the dissolution and flushing capacity of the pollutants, reduce the adhesion of the pollutants to the membrane surface, and make the pollutants easier to be removed.

[0031] Further, in the above technical solution, the top end of the end cover 3 is composed of a hollow structure of multiple resin strips, which not only ensures that the end cover 3 has a certain strength to support and fix the membrane tube 2, but also reduces the obstruction to fluid flow. When the cleaning liquid passes through the ceramic membrane body 1, it can flow more smoothly in the area of the end cover 3. The bottom of each resin strip of the end cover 3 is provided with a bayonet 31, which is matched with the end of the membrane tube 2 and is connected in a clamping manner. The number and position of the bayonet 31 correspond to the membrane tube 2. This design realizes accurate positioning and firm fixing of the membrane tube 2. During the operation of the ceramic membrane, displacement or shaking of the membrane tube 2 due to fluid impact or vibration is prevented, and the filtering performance of the ceramic membrane is stable and reliable. During cleaning, the membrane tube 2 can also be prevented from being damaged or separated from the tube hole 12 due to external force, ensuring the smooth progress of the cleaning work, and facilitating the separate disassembly or replacement of a certain membrane tube 2 when needed.

[0032] The ceramic membrane convenient to clean provided by the utility model has the advantages of convenient cleaning, convenient disassembly and replacement, and stable and reliable filtering performance.

[0033] The integrity of the ceramic membrane body 1 is checked to check whether the tube hole 12 is blocked, deformed or damaged, especially whether the ceramic membrane layer of the inner wall of the tube hole is intact. The installation state of the membrane tube 2 in the tube hole 12 is confirmed to ensure that each membrane tube 2 is firmly fixed by the end cover 3, and that the outer wall of the membrane tube 2 and the inner wall of the tube hole 12 maintain a suitable gap without foreign matter obstruction. Whether the resin strip hollow structure of the end cover 3 is damaged, whether the bayonet 31 can normally clamp the end of the membrane tube 2, and whether the connection of the bolt 32 and the threaded holes 11 on the upper end and the lower end of the ceramic membrane body 1 is fastened are checked to ensure the sealing and connection reliability of the end cover 3 and the ceramic membrane body 1. For the membrane tube 2 of the multi-layer composite ceramic material, whether the layers are combined tightly, whether there are signs of delamination or peeling, and whether the performance of the membrane tube 2 is normal are checked.

[0034] When cleaning is needed, the bolts 32 on both sides of the end cover 3 are unscrewed with appropriate tools, and the end cover 3 is detached from the end of the ceramic membrane body 1. Attention should be paid to protecting the resin strip hollow structure and the bayonet 31 of the end cover 3 during disassembly to avoid damage. For external cleaning of the tube hole 12 and the membrane tube 2, a soft brush with a larger diameter can be used to clean the inner wall of the tube hole 12 and the outer wall of the membrane tube 2 by inserting it into the large-size channel of the tube hole 12, thereby removing the attached large-particle pollutants. Due to the special shape and size of the tube hole 12, the soft brush can be operated more conveniently, and the arc-shaped inner wall angle reduces the cleaning dead angle, thereby improving the cleaning effect.

[0035] For internal cleaning of the membrane tube 2, a high-pressure cleaning nozzle can be used to inject high-pressure cleaning liquid through the end opening of the membrane tube 2 to remove the pollutants inside the membrane tube 2 by using the impact force of the high-pressure water flow, or the membrane tube 2 that cannot be effectively cleaned is directly replaced.

[0036] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
