Abstract

The invention discloses a rotor rotary wing of a pressure screen. The rotor rotary wing comprises a mounting surface, a pulp pushing surface and a pulp suction surface, wherein the pulp pushing surface and the pulp suction surface are connected to form a protruding arc shape; the pulp suction surface is provided with a plurality of rows of grooves which are parallel to one another; and the arrangement direction of the grooves is parallel to a movement direction of the rotary wing. The rotor rotary wing of the pressure screen is mounted on the pressure screen so that operation resistance can be reduced, the screening energy consumption is reduced, a screening process is moderate and the operation is reliable.

Description

technical field [0001] The invention relates to the field of pulping and papermaking machinery, in particular to a pressure screen rotor rotor. Background technique [0002] There are many kinds of impurities in pulp, typically fibrous and non-fibrous impurities such as sediment, metal particles, plastics, rubber, ink, and fiber bundles produced in the pulping process mixed into the pulp from the outside. In order to maintain good, stable and efficient operation of pulp and paper-related operating units, as well as to ensure good quality of semi-finished and finished products, it is necessary to remove various impurities in pulp. [0003] The pressure screen separates impurities based on the different shapes of impurities and good pulp fibers. Typical rotor pressure screens are as follows: figure 1 As shown, its structure is mainly composed of a rotor rotor 1, a sieve plate 2, a pulp inlet pipe 3, a good pulp pipe 4 and a slag discharge pipe 5, wherein the rotor rotor 1 inc...
