Abstract

The invention discloses a composite pressurized screen. The composite pressurized screen comprises a pressurized screen shell and a screening structure formed in the pressurized screen shell, wherein the pressurized screen shell comprises a primary screening shell, a transition shell and a secondary screening shell which are arranged in sequence from bottom to top; the primary screening shell, the transition shell and the secondary screening shell are coaxially arranged; the screening structure comprises a primary screening rotor arranged in the primary screening shell and a secondary screening rotor arranged in the secondary screening shell; the primary screening rotor and the secondary screening rotor are coaxially arranged, and the axis of the screening rotor is coincided with the axis of the pressurized screen shell; the primary screening rotor is a plate rotor; a sieve plate matched with the plate rotor is arranged below the plate rotor; the secondary screening rotor is a cylindrical rotor; a cylindrical screen frame matched with the cylindrical rotor is arranged outside the cylindrical rotor in a sleeving manner. According to the composite pressurized screen disclosed by the invention, two-stage screening is realized, and large-sized impurities in paper pulp can be effectively removed at the coarse pulping stage.

Description

technical field [0001] The invention relates to pressure screen equipment, in particular to a composite pressure screen. Background technique [0002] The pressure screen is a kind of equipment that relies on pressure pulses for screening. It is widely used in the pulping process of the paper industry. It can filter out impurities such as mud, sand, metal particles, plastics, and rubber in the pulp, and at the same time screen out qualified fibers. The utility model relates to a widely used pulping screening and purifying equipment. [0003] At the present stage, the pressure screen is the most widely used screening and purification equipment in the pulping line of the domestic paper industry. Its technology is becoming more and more mature. The pressure screen is adjusted more suitable for domestic papermaking enterprises. [0004] Due to the extensive use of waste paper pulping in my country at present, the content of large particles of impurities in the raw materials is...
