However, the existing mixers can only stir the pulp in the container without a finer grinding function, resulting in uneven beating and affecting the subsequent processing quality, and the slurry at the bottom of the stirring is difficult to be stirred, which will cause a lot of pulp for a long time It settles at the bottom of the container, resulting in a decrease in pulp concentration, or even blocking the pulp conveying pipeline, which has a great impact on product quality and production efficiency

Embodiment Construction
[0024] The present invention is specifically described below in conjunction with accompanying drawing, 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 feed port 7, and the stirring motor 11 is started by the controller 9, and the stirring motor 11 drives the stirring shaft 13 to rotate through the shaft coupling 12, and the stirring blade 16 follows the The rotation of the stirring shaft 13 contacts the slurry, the stirring blade 16 stirs the slurry and breaks it up to separate the fibers, the scraper 41 rotates with the rotation of the stirring shaft 13, and the scraper 41 scrapes the sediment to the first compartment. The slurry on the plate 2 makes the settled slurry rise to the stirring blade 16 to be stirred again. The stirring blade 16 drives the brush plate 39 to rotate, and the bristles on the brush plate 39 brush off the pulp attached to the inner wall of the stirring chamber 4. , the bru...

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. Background technique [0002] Raw pulp is the primary product of the papermaking industry. During the production of raw pulp, stirring equipment is required to continuously stir the raw pulp, so that fibers, water and other chemical raw materials can be diluted and mixed more uniformly, which is convenient for pumping the pulp 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 stir the pulp in the container without a finer grinding function, resulting in uneven beating and affecting the subsequent processing quality, and the slurry at the bottom of the stirring is difficult to be stirred, resulting in a lot of pulp for a long time It settles at the bottom of the container, resulting in a de...
