The invention discloses a high-frequency vibration pressure screen which comprises a housing. A screen barrel is disposed in the center of the housing. A pin holder is fixed below a base. A motor is fixedly disposed outside a frame. A motor shaft is fixedly connected to the end of an eccentric shaft through a coupling. An upper cover is fixedly disposed at an upper opening of the housing. The upper end of the outer periphery of the housing is provided with a material inlet, and the lower end of the outer periphery of the housing is provided with a pulp and residue outlet. By the use of the high-frequency vibration pressure screen, the problem that the existing centrifugal screen and selectifier screen are complex in manufacture process and have high mounting precision requirement is effectively solved, and defects of proneness of meshes or screen slots to blockage, low separating efficiency, high failure rate and poor effect in separation of particles or fibers different in specific gravity are effectively overcome.
Description
technical field [0001] The invention relates to a liquid medium separation device, in particular to a pressure screen with high-frequency vibration effect. Background technique [0002] In textile, papermaking, chemical industry and other corresponding fields, it is often necessary to separate particles or fibers with different sizes, shapes and specific gravity from the liquid medium. At present, the main equipment to achieve the separation of the above-mentioned liquid medium is the centrifugal sieve and Rotary wing screen, since the centrifugal screen and the rotary wing screen are equipped with a cylindrical screen drum in a circular shell, the surface of the screen drum has screen holes or screen slots, and a rotor is installed in the screen drum or several screen drums are installed near the surface of the screen drum. The slurry entering the screen barrel passes through the screen holes or slits under the action of the centrifugal force generated by the rot...
