They are widely used in various fields. In wastewater treatment, silicon carbide ceramic membranes utilize their microporous structure to trap particulate matter on the membrane surface as liquid passes through, thus achieving impurity separation.

[0003] For example, a silicon carbide ceramic membrane wastewater treatment device disclosed in Chinese patent, published on October 31, 2023, with patent publication number CN219922290U, proposes that by starting a motor to drive the mounting plate to rotate, the mounting plate drives the first filter screen and the second filter screen to rotate, thereby completing the rotational filtration of wastewater, reducing the adhesion of impurities on the first filter screen and the second filter screen, and improving the filtration efficiency of the device.

[0004] In the aforementioned prior art, the filter screen is cleaned by a brush when it rotates, thereby reducing the adhesion of impurities. However, after long-term use, the cleaned impurities will accumulate inside the filter tube, and the device is not easy to disassemble, making it difficult to remove the silicon carbide ceramic membrane filter screen for cleaning or replacement. This makes subsequent maintenance of the device inconvenient, increases the difficulty of maintenance and repair, and causes inconvenience to users. Therefore, it is necessary to propose a silicon carbide ceramic membrane wastewater treatment device. Utility Model Content

Multiple extrusion columns 23 are arranged in a ring. The top plate 25 is equidistantly installed on the inner top wall of the sealing cover 22, and the bottom end of the extrusion column 23 is extruded and set on the top of the top plate 25. The extrusion column 23 is set to facilitate the extrusion and fixation of the top plate 25 to the top of the ceramic membrane tube 16, and the top sealing ring 26 increases the sealing effect between the top plate 25 and the ceramic membrane tube 16, thereby facilitating the entry of sewage into the ceramic membrane tube 16 for filtration. The bottom center of the top plate 25 is fixedly connected to the water inlet pipe 28. The center of the top plate 25 has a circular hole, which is vertically set on the top of the water inlet pipe 28. The inner wall of the circular hole of the top plate 25 is fixedly connected to the pull strip 27, and the bottom of the top plate 25 is fixedly connected to the top sealing ring 26.

[0023] Working principle: When using this silicon carbide ceramic membrane wastewater treatment device, open the wastewater valve 5 and the filter drain valve 8, and close the wastewater drain valve 6 and the cleaning valve 7. Wastewater is introduced through the wastewater valve 5 and enters the ceramic membrane tube 16 through the inlet pipe 28. The wastewater is filtered through multiple layers of silicon carbide ceramic membranes.

When cleaning the ceramic membrane tube 16, close the wastewater valve 5 and the filter drain valve 8, and open the wastewater drain valve 6 and the cleaning valve 7. Cleaning water is introduced through the cleaning valve 7 and enters the inner side of the outer casing 11. Then, the multilayer silicon carbide ceramic membrane of the ceramic membrane tube 16 is rinsed. The cleaning water enters the interior of the ceramic membrane tube 16 and washes the impurities upward. Finally, the cleaning wastewater is discharged from the wastewater drain valve 6. When maintaining and repairing the ceramic membrane tube 16, the connecting screw cap 4 is unscrewed from the outside of the connecting screw tube 3. Then, the sealing cap 22 is rotated to remove the sealing cap 22 from the outside of the threaded tube 21, so that the outer shell 11 can be opened. Then, the pull bar 27 is fastened to remove the top plate 25 and the water inlet pipe 28, so that the ceramic membrane tube 16 can be removed for maintenance or replacement, and the interior of the outer shell 11 can be inspected.
