A high-efficiency hydraulic pulper for papermaking and its working method

Abstract

The invention provides an efficient hydrapulper for papermaking. The efficient hydrapulper comprises a hydrapulper tank body, stirring rods, a rotating disc, stirring discs, arc rods, a screen plate, a reduction gear box, a stirring motor, a sucking disc, a storage box, a rotating motor, a conveying pipe, an air pump, a charging opening, an observing opening, a pressure column, a pulp outlet and a slag outlet, wherein a main rotating gear which is connected with the stirring discs, and auxiliary rotating gears which are engaged with the main rotating gear and connected with the stirring rods are arranged in the reduction gear box. According to the efficient hydrapulper for papermaking, paper products in the hydrapulper tank body are stirred and cut at the same time by utilizing the three stirring rods and stirring discs, so that the stirring efficiency is improved; the three auxiliary rotating gears are driven to rotate by the main rotating gear of the reduction gear box, thereby effectively saving energy sources and reducing energy consumption; meanwhile, suspension materials on the surface of pulp liquid are removed by utilizing the sucking disc on the rotating disc, so that the normal rotation of the motor is effectively protected, and the service life of the hydrapulper is prolonged.

Description

technical field [0001] The invention relates to a high-efficiency hydraulic pulper for papermaking and a working method. Background technique [0002] In the paper industry, the hydraulic pulper is one of the most commonly used pulping equipment in the pulp and paper industry. It mainly crushes pulp boards, waste books, waste cartons and other waste items. In the process of recycling, it must be Repulp waste paper, old newspapers or other waste paper products to ensure the normal operation of subsequent production equipment and the purity of finished products. The purpose of waste paper pulping is to eliminate fiber bundles without cutting or avoid cutting fibers as much as possible, while trying not to destroy various non-fibrous impurities. In the prior art, the pulper mostly uses a single shaft, the pulping speed is slow, and the production efficiency is not ideal, and there are often some agglomerated suspended matter in the upper layer of the slurry in the pulper, and ...

Problems solved by technology

In the prior art, the pulper mostly uses a single shaft, the pulping speed is slow, and the production efficiency is not ideal, and there are often some agglomerated suspended matter in the upper layer of the slurry in the pulper, and the pulper cannot be well processed. These suspended solids are cut, too much suspended solids will cause the motor to be stuck and affect the service life of the pulper
