Description

Technical Field

[0001] The utility model specifically relates to a fiber separation device for dust-free paper production, belonging to the technical field of fiber separation. Background Art

[0002] Dust-free paper is a kind of dry-laid nonwoven fabric with unique physical properties, such as high elasticity, softness, excellent hand feel and drape, extremely high water absorption and good water retention. It is widely used in sanitary care products, special medical products, industrial wiping products and other fields. During the production process of dust-free paper, due to the presence of impurities in the pulp, in order to improve the purity of the pulp fiber, a fiber separation device for dust-free paper production is required to extract high-purity pulp fibers, thereby improving the quality of dust-free paper.

[0003] As disclosed in the publication number: CN217678313U, a fiber separation device for dust-free paper production includes a box body, a first servo motor is arranged on the top of the box body, a first rotating rod is fixedly connected to the bottom of the first servo motor, a stirring cutting blade is fixedly connected to the outer surface of the first rotating rod, a discharge pipe is arranged at the bottom of the box body, a filter device is arranged at the bottom of the discharge pipe, a filter plate is arranged on one side of the filter device, and a transmission device is arranged on one side of the box body. In the utility model, the rotation of the second servo motor drives the spiral blade to rotate to draw up the pulp at the bottom of the box body and then discharge it into the box body through the discharge port, so as to complete the circulation stirring of the raw materials and increase the stirring efficiency. While the spiral blade extracts the raw materials, the crushed stone and scrap iron in the device can be sucked into the top of the closed cover, and the pulp flows into the box body 1 for secondary stirring, and the crushed stone and scrap iron remain in the closed cover due to its own weight.

[0004] When a common fiber separation device for dust-free paper production is used, although the impurities in the device can be sucked into the top of the closing cover by the spiral blade, the pulp flows into the box for secondary mixing, and the crushed stone and scrap iron remain in the closing cover due to their own weight, thereby improving the mixing efficiency, the cleaning effect on the inner wall of the separation box is poor. Usually, the staff cleans it manually or with a nozzle, which is time-consuming and labor-intensive, and the cleaning efficiency is low. In addition, it is difficult to remove the separated impurities, which is usually done manually and is inconvenient. Utility Model Content
