[0002] Ceramic filters are widely used in many industries such as mining, chemical industry, and pharmaceutical industry due to their high-efficiency filtering performance. During long-term operation, solid particles in the core component filter plate will gradually block the filter channels, resulting in a significant decrease in filtering efficiency.

[0003] The existing ceramic filter flushing structure generally uses clean water as the backwashing medium.

By arranging the second flow sensor and the first flow sensor on the central area air impingement plate and the edge area air impingement plate, the tiny flow changes of the filtrate in the area during the filtration process can be monitored in real time, and the back-air impingement process can realize adaptive adjustment of the blockage conditions of different areas of the filter plate to ensure that each area can be properly cleaned.

[0011] As a preferred embodiment of the ceramic filter plate anti-air impulse structure and its construction method provided by the present invention, the anti-air impulse assembly includes a fixed frame installed on the side of the ceramic filter body, and the upper and lower side edges of the fixed frame are respectively slidably matched with a central area air impulse plate and an edge area air impulse plate located on one side of the filter plate.

[0012] As a preferred embodiment of the ceramic filter plate anti-air impact structure and construction method provided by the present invention, a plurality of first nozzles and a first flow sensor are installed on the side of the edge area air impact plate close to the filter plate, and a plurality of second nozzles and a second flow sensor are installed on the side of the center area air impact plate close to the filter plate.

The second flow sensor and the first flow sensor arranged on the central area air flushing plate and the edge area air flushing plate can monitor the slight flow change of the filtrate in the area during the filtration process in real time. When the flow in a certain area changes, the second flow sensor and the first flow sensor respectively deliver the signal to the second flow control valve and the first flow control valve. For areas with severe blockage, the opening of the control valve can be increased to increase the air supply pressure, and the back-gas flushing time can be appropriately extended. For areas with relatively light blockage, lower pressure and shorter time are used for back-gas flushing, so as to realize the back-gas flushing process. Adaptive adjustment of the blockage conditions of different areas of the filter plate is achieved, ensuring that each area can be properly cleaned, avoiding damage to the filter plate caused by excessive back-gas flushing, and effectively extending the service life of the filter plate;

For areas with severe blockage, the air impact plate can be controlled to move toward the filter plate and make close contact with it to achieve a better air impact effect. For areas with relatively light blockage, the air impact plate can be controlled to move away from the filter plate, thereby achieving adaptive adjustment of the air impact plate to the blockage conditions of different areas of the filter plate during the reverse air impact process.

[0021] Compared with the prior art, the present invention has the following beneficial effects: a central area air baffle plate and an edge area air baffle plate are arranged on one side of the filter plate, and the air pump transports clean air through the air inlet bin to the first nozzle and the second nozzle to perform air backwashing on the filter plate, thereby saving the amount of water used for backwashing of the ceramic filter body using water as the flushing medium and the use of filter elements. By arranging the second flow sensor and the first flow sensor on the central area air baffle plate and the edge area air baffle plate, the tiny flow changes of the filtrate in the area during the filtration process can be monitored in real time, thereby realizing adaptive adjustment of the blockage conditions of different areas of the filter plate during the back-air flushing process, and ensuring that each area can be properly cleaned.
