Three-layer forming net for papermaking

Abstract

The invention relates to the technical field of papermaking equipment, particularly to a three-layer forming net for papermaking. The three-layer forming net comprises a forming device, a supporting frame and a main water absorption device body, wherein the forming device is fixedly installed in the supporting frame; the main water absorption device body is fixedly mounted at the edge of one innerend of the support frame; the three-layer forming net is movably mounted in the forming device; a driving roller is connected to the inner surface of the three-layer forming net in a close contact mode; positioning shafts are welded to the two end faces of the driving roller; one end of each positioning shaft is fixedly connected with a first driving motor; a support framework is fixedly installed in the supporting frame; and a guniting opening is welded to the top face of the support framework. Paper pulp can be filtered through the three-layer forming net, the retention rate of paper pulp fibers on the surface of the three-layer forming net can be increased, water absorption is conducted on the paper pulp on the bottom face of the three-layer forming net through an absorbent wool conveying belt, and therefore, the dehydration speed and the production efficiency of the forming net are improved.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a three-layer forming wire for papermaking. Background technique [0002] In the papermaking industry, pulp is turned into paper through a series of equipment and processes. The paper machine is the main equipment of the papermaking industry. During the papermaking process of the paper machine, the pulp is transported to the headbox and sprayed to On the surface of the forming wire, the water inside the pulp will flow out through the gaps inside the forming wire to filter the pulp, so that the pulp inside the paper scraps will stay on the surface of the forming wire to form a wet paper layer, and then the wet paper layer will be transported to the downstream The process is dehydrated and dried to form finished paper. [0003] At present, the forming wire is generally divided into one layer or two layers, resulting in large gaps inside the forming wire, causing a pa...

AI Technical Summary

Problems solved by technology

[0003] At present, the forming wire is generally divided into one layer or two layers, resulting in large gaps inside the forming wire, causing a part of paper scraps inside the pulp to be lost along with the water, resulting in a low retention rate of pulp fibers on the surface of the forming wire, resulting in Production waste increases the production cost, so the existing forming fabric for papermaking uses a three-layer forming fabric to filter the pulp, but the internal gaps of the three-layer forming fabric are small, which will make the dehydration speed of the forming fabric very slow, thus restricting In order to improve the production efficiency, a three-layer forming fabric for papermaking is needed to solve the problems raised above
