1. The pressure screen adopts the structure design of the bottom, bottom discharge slag and top row slag, which effectively solves the above problems. Light impurities and the air in the slurry naturally rise to the top discharge outlet, the heavy impurities enter the body to the bottom out. In this way, on the one hand, it can effectively shorten the residence time of impurities in the sieve area, reduce the possibility of impurity circulation, and improve the screening efficiency. On the other hand, it can prevent the damage caused by heavy impurities to the rotor and sieve drum, and prolong the service life of the equipment. 2. Structural characteristics 1, sieve drum: fine sieve drum sieve sieve seam width h0.15 mm, use water jet cutting technology grooving on 8 mm thick steel plate, no burr forming excellent round hole and slot, won't produce stress and like mechanical washing grinding groove groove end fracture. It can also provide hard contact process to improve wear resistance. 2. Rotor rotor: the rotor is equipped with 3-4 rotor blades, and the balance is strictly calibrated after assembly. It is the rotor that does not produce vibration when rotating at high speed. The rotor is mounted on the main shaft, and the rotor is mounted on the rotor through the screw rod. The gap between the rotor and the sieve drum can be adjusted. The coarse - screen rotor adopts drum - type external rotary-wing structure and corrects dynamic balance. This structure prevents the impurity winding rotor from affecting the normal work of the equipment. 3. Outer shell: consists of upper cover and barrel body. The lower part of the tube is cut into the plasma pipe. The center of the barrel is provided with a slurry pipe. The top cover is equipped with a slag drain and a flushing nozzle. 4. Transmission device: including motor, pulley, v-belt, belt tensioning device, spindle and bearing. Process customization: brand: Model: uv102 material: stainless steel
