Description

Technical Field

[0001] The utility model relates to the technical field of paper pulp slag removal in papermaking, in particular to a pulp slag removal device for clean papermaking. Background Technique

[0002] Papermaking is an important invention of ancient Chinese working people, which is divided into two forms: machine-made and handmade. The machine-made form is continuous on a paper machine. The pulp suitable for the paper quality is diluted with water to a certain concentration, initially dewatered at the wire part of the paper machine to form a wet paper sheet, then dewatered by pressing, and then dried into paper. Among them, clean papermaking refers to ensuring the cleanliness of raw materials and finished products in the process flow to the greatest extent during the papermaking process. Therefore, in this type of papermaking process, a slag removal device is needed to remove slag and filter the raw material pulp. However, in the existing pulp slag removal device for clean papermaking, when removing slag from the pulp, as the filtration time increases, large particle fibers or sundries in the pulp will continuously accumulate on the filter screen, thereby causing the large particle fibers or sundries in the pulp to block the filter screen, affecting the filtration effect of the pulp.

[0003] In view of the above problems, it is necessary to provide a pulp slag removal device for clean papermaking that can effectively avoid blockage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a pulp slag removal device for clean papermaking to solve the problems raised in the above background technique.

[0026] Specifically, the cleaning assembly 3 includes a fixing plate 301 fixedly installed at the bottom of the rotating shaft 112, a second telescopic guide rod 302 is fixedly connected to the bottom of the fixing plate 301, a connecting plate 303 is fixedly connected to the bottom of the second telescopic guide rod 302, a matching spring 305 is arranged at the position between the outer side of the second telescopic guide rod 302 and between the fixing plate 301 and the connecting plate 303, a cleaning brush 304 is detachably installed at the bottom of the connecting plate 303, and by regularly replacing the cleaning brush 304, the cleaning effect can be effectively guaranteed. A plurality of second telescopic guide rods 302 are provided, and the plurality of second telescopic guide rods 302 are equidistantly distributed along the length direction at the bottom of the fixing plate 301. The cleaning brush 304 contacts but is not connected to the top of the slag removal filter screen 111 under the action of the matching spring 305. By controlling the operation of the first motor 106, the first motor 106 drives the rotating shaft 112 to rotate, thereby driving the fixing plate 301 to rotate, driving the connecting plate 303 and the cleaning brush 304 to rotate under the action of the second telescopic guide rod 302.
