Cylinder structure of drum pulper

Abstract

The invention discloses a cylinder structure of a drum pulper. The cylinder structure comprises a horizontal drum cylinder which is axially divided into multiple operation sections, the operation sections are a preimpregnation section, a beating section and a screening section in sequence from front to back, the drum cylinder at the beating section is divided again into multiple secondary operation sections along the axial direction, the secondary operation sections are a primary beating section, a primary screening section and a re-beating section in sequence from front to back, and the screening section is a fine screening section; lifting board sets are arranged on the inner wall of the drum cylinder at the preimpregnation section, the primary beating section, the primary screening section, the re-beating section and the fine screening section, each lifting board set comprises multiple lifting boards arrayed uniformly and peripherally, and each lifting board is arranged axially and fixedly connected with the corresponding inner wall of the drum cylinder; mesh groups are arranged in the drum cylinder at the primary screening section and the fine screening section. By the cylinder structure, length of equipment can be reduced effectively, power consumption of equipment is reduced, and screening efficiency of equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of pulping equipment, in particular to a cylinder structure of a drum pulper. Background technique [0002] Drum pulper is a new type of advanced waste paper pulping equipment, and it is a replacement product of traditional hydraulic pulper. The main structure of the equipment is a specially designed drum device with a slight inclination—the front section is the crushing area, and the rear section is the screening area. During the working process, the drum rotates at a certain speed, and waste paper raw materials, water and suitable chemicals are continuously added from one end of the drum to mix together, and the lifting board inside the drum continuously picks up and drops the wet waste paper , and slowly move from the pulping area to the screening area. The impact and friction generated by this action can "mildly" loosen the waste paper fiber, and maintain the strength of the fiber better; at the same t...

Problems solved by technology

In this way, it is necessary to ensure that the length of the drum crushing area and the screening area is long enough, so that the waste paper can completely become qualified fibers and enter the pulp tank without being discharged from the tail of the screening area, resulting in the overall length of the equipment, large footprint, and many Due to limited space, the enterprise cannot adopt this energy-saving equipment

At the same time, the good products that have been crushed in the crushing area cannot be discharged out of the cylinder, and move with other impurities and unshredded waste paper, which increases the power consumption of drum crushing
