Background technique

As shown in FIG. 1 , the currently known disc cleaning device is an energy-concentrating ultrasonic cleaning machine, which is composed of a water tank, a disc station fixing device, a mechanical transmission device, an ultrasonic generator, an inlet and a drain device, and the like. Put an appropriate amount of water in the sink and maintain a certain liquid level, place the disc on the disc station fixing device and fix it, turn on the mechanical transmission device, keep the disc rotating at the fixed position of the station, start the ultrasonic generator, and generate The high-frequency voltage is transmitted to the transducer by the cable connection line, the ultrasonic generator generates high-frequency resonance, and generates ultrasonic waves. Inflow, in order to clean the rotating disc.

The outer diameter of existing filter discs is divided into 15 inches, 12 inches, 8 inches, 5 inches, etc., but the inner diameter of the hole is generally 85mm and remains unchanged; the disc station fixture of the traditional energy-concentrating ultrasonic cleaning machine is shown in Figure 1 and As shown in Figure 3, the disc is placed horizontally into the chuck of the circular station fixture. The outer edge of the disc is in close contact with the jaws of the four station fixtures. When cleaning discs of other sizes, it needs to be cleaned again. It is very inconvenient to replace the disc station fixture of the corresponding size, which greatly reduces the work efficiency.

Features, high filtration efficiency. When filtering in production, the high-pressure molten liquid suddenly becomes smaller when it passes through the disc sintered felt and the sintered felt protective net. The sudden increase in pressure allows the melt to enter evenly. When the molten material enters the splitter plate and support plate evenly, the cross section of the flow channel becomes larger suddenly, and the pressure gradually decreases, so that the molten material flows evenly to the next process, and the flowing molten material fills every gap in the disc, and no retention occurs , successfully completed the filtration process. However, when using the existing energy-concentrating ultrasonic cleaning machine to clean the filter disc, no liquid flows through the internal flow channel of the filter disc, and the splitter plate and support plate inside the disc sintered felt form a structure similar to a "maze". The structure is tight, and the filter width of the disc is wide, and it is blocked by the surface of the disc sintered felt and the protective net, so it is difficult to clean; the internal flow channel of the filter disc is cleaned by ultrasonic waves, and the liquid flows out through the internal flow channel because there is no special It is difficult to completely clean the particles inside the disc; after ultrasonic cleaning, the carbon deposits and other particles in the disc can also be knocked out from the ring holes of the filter disc.
