[0002] High-porosity silicon carbide ceramic membranes are a new type of ceramic material with special structure and excellent performance. With silicon carbide (SiC) as the main component, they have high strength, high hardness, high temperature resistance, and corrosion resistance. The porosity is usually between 40% and 80%, which is in the high porosity range. The pore size distribution is uniform and controllable, and micron-level or nano-level filtration can be achieved. It is a rigid skeleton structure formed by the interconnection of silicon carbide grains or fibers.

However, existing silicon carbide ceramic membranes have a simple structure, making them inconvenient to insert and fix within tubular filtration equipment. They also have poor fixation stability. Furthermore, removing the core of a column-type silicon carbide ceramic membrane can easily cause wear and damage to its surface, making maintenance and cleaning difficult. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a high-porosity silicon carbide ceramic membrane, comprising: a columnar silicon carbide ceramic membrane body 1, a floating tube plate 2, a fixed tube plate 3, a floating fixing component 4, and a connecting reinforcement component 5;

[0025] The floating tube plate 2 is fixedly installed at one end of the outer wall of the columnar silicon carbide ceramic membrane body 1, and the fixed tube plate 3 is fixedly installed at the other end of the columnar silicon carbide ceramic membrane body 1. The fixed tube plate 3 is "T" shaped so that one end of the fixed tube plate 3 is fixed to one side of the tube shell, which facilitates the extraction of the columnar silicon carbide ceramic membrane body 1. The floating fixing component 4 is installed on the outer wall of the floating tube plate 2, and the connecting reinforcing component 5 is installed between the floating tube plate 2 and the fixed tube plate 3.

[0026] As a preferred embodiment, the floating fixing component 4 further includes: a plug 41, a rotating plug 42, an inner pentagonal hole 43, and a limiting block 44;

[0027] In order to support and fix the floating tube sheet 2, several insert posts 41 are inserted into the outer wall of the floating tube sheet 2 along the circumference, and several rotating posts 42 are screwed into one side of the floating tube sheet 2 along the circumference. One end of the rotating post 42 is provided with an inner pentagonal hole 43, and a limiting block 44 is fixedly set on one side of the insert post 41.

[0028] As a preferred embodiment, the other end of the rotating column 42 is inclined inward from left to right, and one end of the insertion column 41 contacts one side of the rotating column 42. When the rotating column 42 rotates, the insertion column 41 is pushed to move by the inclined surface of the rotating column 42.

[0029] As a preferred option, the limiting block 44 is further inserted into one side of the inner cavity of the floating tube plate 2 to limit the movement of the insertion post 41.

[0030] As a preferred option, one end of the insertion post 41 is arc-shaped so that one end of the insertion post 41 contacts the inner wall of the tube shell.

[0031] As a preferred embodiment, the connection reinforcement component 5 further includes: a connecting rod 51, a stop block 52, and a fastening nut 53;

[0032] In order to improve the overall strength of the column-type silicon carbide ceramic membrane body 1, several connecting rods 51 are inserted into one side of the fixed tube plate 3, and a stop block 52 is fixedly set at one end of the connecting rod 51, and the stop block 52 is in contact with one side of the fixed tube plate 3; a fastening nut 53 is screwed onto one end of the connecting rod 51 extending out of one end of the floating tube plate 2, and the fastening nut 53 is tightly attached to one end of the floating tube plate 2.

[0033] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0034] Tighten the fastening nut 53 to fix the connecting rod 51 between the floating tube plate 2 and the fixed tube plate 3, thereby improving the overall tensile strength of the column-type silicon carbide ceramic membrane body 1. When inserting the column-type silicon carbide ceramic membrane body 1 into the tubular filter, make the insert 41 contact the inner wall of the tube shell for insertion. After inserting the column-type silicon carbide ceramic membrane body 1 into the tubular filter, rotate the rotating column 42 through the inner pentagonal hole 43 to make the rotating column 42 rotate and move to one side, so that one side of the rotating column 42 pushes the insert 41 within the limit block 44. The tube plate 2 moves outward until the insertion post 41 supports the inner wall of the tube shell. By controlling the insertion post 41 on the outside of the floating tube plate 2 to move outward and contact the inner wall of the tube shell, the floating tube plate 2 and one end of the columnar silicon carbide ceramic membrane body 1 are fixed, which has strong stability. When the columnar silicon carbide ceramic membrane body 1 is extracted, it can avoid contact between the columnar silicon carbide ceramic membrane body 1 and the inner wall of the tube shell under the support of the connecting rod 51, so as to protect the outer wall of the columnar silicon carbide ceramic membrane body 1. Core extraction is convenient and easy to maintain and clean.
