Description

Pulper for papermaking

Technical Field

The utility model relates to a pulper for papermaking belongs to papermaking equipment technical field.

Background

Hydropulper is a hydraulic and mechanical pulper for breaking up water-soaked pulp boards, waste paper (cardboard), etc. into pulp fibre suspensions by means of hydraulic and mechanical forces, and separating heavy and large impurities from fibres.

When the hydraulic pulper works, a rotor (or a cutter head) at the bottom of the tank body rotates at a high speed, materials contacting with the rotor (or the cutter head) are thrown to the peripheral area from the central area at the bottom in the tank body, then flow from bottom to top along the tank wall, flow to the central area from the peripheral area at the upper part, and sink to the cutter head from the central area to form a circulating flow in the vertical surface direction. Meanwhile, due to the rotary drive of the rotor (or the cutter head), materials on the upper horizontal plane, the middle horizontal plane and the lower horizontal plane in the groove body form horizontal rotary flows. The pulp board or waste paper (paperboard) is fully swelled in the dilution water and the bonding strength is rapidly reduced, most of the energy output by the rotor (or cutter disc) is transmitted to water, and very strong stirring and shearing are generated by water power, the rotor (or cutter disc) directly acts on the pulp board or waste paper to impact, tear or rub the pulp board or waste paper (paperboard) and rub and knead the pulp board or waste paper (paperboard) mutually, and thus the pulp crushing function is rapidly completed.

The existing pulper generally filters through a screen in the pulping process, but the filter screen is blocked, so that the maintenance is troublesome.
