Drum pulper- paper pulp processing machine

Product introduction:

The drum pulper integrates pulping and screening, and is especially suitable for the pulping of unselected waste paper materials. For expanding the recycling and utilization of secondary fibers, reducing environmental pollution and saving energy.
Structure principle
The machine has a roller-shaped drum with simple structure and novel design. It is composed of an upper hopper, a rotating drum, a transmission device, a supporting wheel device, a blocking wheel device, a sealing device, a shield and a slurry tank. The outer wall of the drum is inlaid with two large supporting wheels and a large gear. The two large supporting wheels are supported by two groups of small supporting wheels respectively, and can rotate on the small supporting wheels. On both sides of the large supporting wheel on the pulp outlet side, there are a set of blocking wheel devices to prevent the axial displacement of the drum. The large gear on the outer wall of the drum is driven by the small gear of the transmission device to rotate the drum. The front part of the drum is the pulping zone, and the rear part is the screening zone. The feed port of the pulping zone is connected with the upper hopper by a sealing device. The upper hopper is equipped with water inlet and medicine inlet nozzles; the screening area has a protective cover, dilution water and a slurry tank. The waste paper enters the drum from the upper hopper, the pulp enters the slurry tank in the screening area through the pulping zone, and the impurities are discharged from the slag discharge port.

The dilution water comes from the spray pipe installed on the top of the drum, and is sprayed through the sieve plate at the top of the drum from the outside to the inside, so that the fibers that block the sieve can be backwashed back into the drum, which not only cleans the sieve but also flushes impurities Adhesive fibers on the top.
