Description

Technical Field

[0001] The utility model relates to the technical field of filters, and in particular to a disc-type ceramic membrane filter. Background Art

[0002] Ceramic membrane, also known as inorganic ceramic membrane, is an asymmetric membrane made of inorganic ceramic materials through a special process. Ceramic membranes are divided into tubular ceramic membranes and flat ceramic membranes. The wall of the tubular ceramic membrane is densely covered with micropores. Under pressure, the raw liquid flows inside the membrane tube or outside the membrane, small molecules pass through the membrane, and large molecules are retained by the membrane, thereby achieving the purposes of separation, concentration, purification and environmental protection. The surface of the flat ceramic membrane is densely covered with micropores. Within a certain membrane pore size range, the permeability is different depending on the molecular diameter of the penetrating substance. The pressure difference on both sides of the membrane is the driving force, and the membrane is the filter medium. Under a certain pressure, when the feed liquid flows through the membrane surface, only water, inorganic salts, and small molecules are allowed to pass through the membrane, while large molecules such as suspended matter, glue and microorganisms in the water are prevented from passing through.

[0003] After searching, the Chinese patent with announcement number: CN217490421 U discloses a disc-type rotating ceramic membrane separation equipment for high-concentration material processing, wherein the upper end of the shell is fixedly connected with a liquid inlet pipe, the bottom of the shell is fixedly connected with a trapezoidal base, the inner wall of the trapezoidal base is fixedly installed with a driving motor, the output shaft of the driving motor is fixedly installed with a fixed pipe, both ends of the fixed pipe are fixedly connected with connecting pipes, the outer end of the connecting pipe is fixedly connected with a nozzle, and the outer end of the nozzle is fixedly installed with a sliding ring. The utility model starts the driving motor to drive the fixed pipe to rotate, so that the connecting pipe drives the nozzle and the sliding ring to move. When the material enters the inside of the shell through the liquid inlet pipe, the ceramic membrane filters the sewage, and the large particles that cannot pass through the ceramic membrane remain on the top of the ceramic membrane. The top of each group of ceramic membranes is sprayed with water through the nozzle, so that the large particles of impurities will not block the ceramic membrane.

[0004] The existing devices have some disadvantages during use. For example, the ceramic membrane in the above scheme is inconvenient to disassemble, so it is difficult to maintain or replace the ceramic membrane, which reduces the filtering effect. Specifically, if the ceramic membrane is difficult to disassemble, then when the ceramic membrane needs to be cleaned or replaced, the operator may need to spend more time and energy, and may even need to use special tools or equipment, which not only increases maintenance costs, but may also affect the efficiency of the filter.
