Technical Field

The utility model relates to the field of filtration technology, especially, relate to a screen frame that quick lock is difficult for pine to take off.

Background

Filter screen filtration is one of the filtration techniques that has emerged earlier. Are now in large use by the industrial sector. The mechanism of filter screen filtration is that when a gas containing dust or solid particles passes through the filter material screen, only the gas is allowed to pass through, while the dust is retained on the surface of the filter material. The retention is caused by the interaction of several mechanisms, such as diffusion, hooking, inertia, sieving, gravity, etc. In order to maintain a large filtering area, the filter screen needs to be sleeved on the filter screen frame. At present, the filter screen frame adopts a buckling mode and a threaded connection mode, but the buckling mode can cause insecure connection, the end face sealing problem is not good, and the threaded connection has the problems of labor and time consumption in connection.
