Embodiment Construction

[0024] The present invention will be specifically described below in conjunction with the accompanying drawings, such as Figure 1-5 shown:

[0025] In this embodiment, the slurry is put into the stirring chamber 4 of the tank body 1 through the feeding port 7, the stirring motor 11 is started by the controller 9, and the stirring motor 11 drives the stirring shaft 13 to rotate through the coupling 12, and the stirring blade 16 The rotation of the stirring shaft 13 makes it contact with the slurry, the stirring blade 16 stirs the slurry and disperses it to separate the fibers, and the scraper 41 rotates with the rotation of the stirring shaft 13, and the scraper 41 scrapes and precipitates to the first partition. The slurry on the plate 2 makes the precipitated slurry rise to the stirring blade 16 to receive stirring again. The stirring blade 16 drives the brush plate 39 to rotate, and the bristles on the brush plate 39 brush the pulp attached to the inner wall of the stirring...

Abstract

The invention discloses a pulp beating and refining device for papermaking production, comprising a tank body, a pulp stirring mechanism and a pulp grinding mechanism, wherein the tank body is provided with a first partition plate and a second partition plate, the first partition plate and the second partition plate divide the inner cavity of the tank body into a stirring chamber, a grinding chamber and a functional chamber from top to bottom in sequence, and the tank body is provided with a feeding port, a discharging port and a controller. The pulp stirring mechanism comprises a motor bracket, a stirring motor, a stirring shaft and stirring blades. The pulp grinding mechanism comprises a protective shell, a reducer, an upper grinding disc, a lower grinding disc, and a grinding groove. Agrinding gap adjusting mechanism comprises a lifting push plate, a push rod, a sliding rod, a fixed seat, a first slider, a second slider, a first hinge rod, a first cross rod, a second hinge rod, a second cross rod and a bidirectional servo cylinder. The first partition plate is provided with a material discharging pipe communicating with the stirring chamber and the grinding chamber, the material discharging pipe is connected in series with a solenoid valve. The pulp beating and refining device has the advantages of simple structure and strong practicability.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a beating and refining device for papermaking production. Background technique [0002] Pulp virgin pulp is the primary product of the paper industry. During the production process of pulp virgin pulp, stirring equipment is required to continuously stir the virgin pulp, so that the fiber, water and other chemical raw materials can be diluted and mixed more uniformly, which is convenient for the pulp pump to be pumped to the papermaking industry. The next paper pulping equipment in the pulping process can better improve the quality of the final paper product. However, the existing mixers can only agitate the pulp in the container, and have no finer grinding function, resulting in uneven beating, affecting the subsequent processing quality, and the pulp at the bottom of the mixing layer is difficult to be stirred, which will cause a lot of pulp for a long time. Preci...
