A continuous hydraulic pulper

Abstract

The invention relates to the technical field of pulping equipment, and discloses a continuous hydraulic pulper, which includes a tank body, a fixing seat and supporting legs, and the fixing seat is fixedly installed on the bottom of the outside of the tank body and is symmetrical to the center of the tank body , the supporting legs are fixedly installed on the top of the tank body and there are four and fixedly connected by connecting rods. The tank body and the impact water pipe are set so that after the slurry enters the slurry inlet cavity, it is driven by the high-pressure pump to impact the slurry in the inner cavity of the tank, and the slurry is driven to rotate and stir, so that the waste paper is decomposed, which is different from the existing one. Compared with the existing technology, the present invention removes the traditional mechanical drive, effectively reduces mechanical damage and improves the quality of fibers through pure hydraulic drive, and at the same time, through the tiny bubbles injected from the bubble disc, a part of the bubbles can lift the slurry from bottom to top, Improve the uniformity of the fiber and accelerate the decomposition efficiency, and another part of the air bubbles will expand or rupture after combining with the fiber, further accelerating the fiber decomposition efficiency.

Description

technical field [0001] The invention relates to the technical field of pulping equipment, in particular to a continuous hydraulic pulper. Background technique [0002] 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, etc. The traditional hydraulic pulper is driven by a motor to start rotating the impeller, and the pulp in the tank It is inhaled along the center of the axis and thrown out from the circumference at high speed, forming a violent turbulent cycle. Due to the tearing of the impeller wings and the mutual wetting of the slurry flow layers at different speeds, a huge friction effect is generated, so that the slurry is in a wet state. Strongly decompose and separate fibers, but there are some deficiencies in traditional hydropulpers, as follows: [0003] The impeller is used to stir the slurry, which inevitably contacts the fiber bundles in the slurry.

Problems solved by technology

[0003] The impeller is used to stir the slurry, which inevitably contacts the fiber bundles in the slurry. The high-speed rotating impeller has a shearing effect on the fibers, and at the same time cuts the impurities in the waste paper into small pieces, which affects the quality of the slurry. At the same time, the traditional hydraulic pulper is divided into three types: high consistency, medium consistency and low consistency. It is necessary to control the concentration of the slurry during work. Blockage, resulting in the inability to carry out follow-up work, making it impossible to achieve continuous production, resulting in low production efficiency
