Background

The pressure screen is a device for continuously screening pulp under pressure in a completely closed state, pulp which is under pressure and is not screened during operation enters a separation chamber at the upper part of the pressure screen from a pulp inlet pipe along a tangent line, and heavier objects are separated out under the action of centrifugal force, settled in a heavy slag collecting tank and discharged from a heavy slag outlet. The rotor structure of the pressure screen is usually that a plurality of regularly arranged rotary wings are arranged on the surface of a cylinder or a cantilever rod. The positive pressure and the negative pressure are formed on the surface of the rotor blade in sequence in the process of high-speed rotation. When the rotor blades generate positive pressure, the pulp is pressed to the screen cylinder, and qualified fibers and water in the pulp are forced to smoothly pass through the screen holes or screen gaps. The pressure screen is as the equipment of a purification and screening, uses the back for a long time, causes the inside scale deposit of appearing of equipment and the phenomenon of jam easily, and the screening ability of pressure screen can descend, influences the operation of pressure screen, and jam or a large amount of scales deposit when appearing need carry out the shut down clearance maintenance with the pressure screen to guarantee the production operation of pressure screen, the inside clearance of pressure screen is comparatively hard simultaneously.
