Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a recovery equipment for papermaking pulp, so as to solve the problem in the prior art when using the vortex concave air flotation machine to recycle the paper pulp produced in papermaking. The slurry is thicker and it is easier to adhere to the surface of the scraper chain plate. At the same time, when the scraper chain plate is exposed to the air, the attached paper pulp will be on the surface of the scraper chain plate after it comes into contact with the air. Form hardened agglomerates, which are not easy to be removed, and in the next scraping work, because the hardened paper pulp is lengthened and the scraping chain plate is thickened, the scraping chain plate is longer than the normal length of the scraping chain plate , extending into the inside of the air flotation tank, so that when the slag scraper chain slides the paper slurry close to the slag return tank, the barrier between the slag return tank and the air flotation tank appears to block the phenomenon, resulting in the entire slag scraper chain stuck, malfunctioning defect

[0039] Such as Figure 4 , Figure 5 , Figure 8 As shown, the present invention provides a kind of technical scheme of the recovery equipment of papermaking slurry:

[0040] Such as Figure 4-Figure 5 As shown, a papermaking slurry recovery equipment, its structure includes that one end of the connecting shaft sleeve 6b2 is connected through the sleeve frame column 6b3, and the other end is respectively connected through the connection with the slag suppression mechanism 6c, which is beneficial to realize the paper alignment. The slurry is used for absorbing fit.

[0041] Such as Figure 5 As shown, the sub-chamber 6b4 includes a frame plate 6b41, a moving rod 6b42, and a wiping bag 6b43. The moving rod 6b42 is provided with several pieces and is installed on both sides of the inner wall of the frame plate 6b41 in an irregular shape. The moving rod 6b42 is vertically connected with the frame plate 6b41 by electric welding, and several wiping capsules 6b43 are installed o...

Abstract

The invention discloses recycling equipment for papermaking residue pulp. The recycling equipment structurally comprises an equipment main body, an aeration machine, an air floatation tank, a residue return tank, a residue scraping chain plate and a wiping device. The recycling equipment has the beneficial effects that when a friction strip and a scraping rod are in fit contact with the residue scraping chain plate, paper residue pulp attached to the surface of the residue scraping chain plate is subjected to fit scraping stroking, so that hardening caused by the fact that a large amount of paper residue pulp is retained on the surface of the residue scraping chain plate is avoided, the residue scraping length and thickness of the residue scraping chain plate are increased, thus the residue scraping chain plate extends into the air flotation tank compared with a normal chain plate, and the phenomenon that the residue scraping chain plate is stuck and still appears when the residue scraping chain plate touches a partition plate arranged between the air flotation tank and the residue return tank, a wiping bag in a branch cavity is used for removing the paper residue pulp on the surface of a stroking and scraping piece, it is ensured that the stroking and scraping piece can be recycled, retained paper residue pulp cannot return to the air floatation tank, and meanwhile, the scraped paper residue pulp is absorbed in a centralized mode in cooperation with a residue return restraining mechanism and conveyed into the residue return tank.

Description

technical field [0001] The invention relates to the field of pulp recovery equipment, more precisely, it relates to a recovery equipment for pulp from papermaking. Background technique [0002] When using the vortex concave air flotation machine to recycle the paper sludge produced in papermaking, because the paper sludge is relatively thick and it is easier to attach to the surface of the scraping chain plate, and at the same time cooperate with the scraping chain plate when exposed to the air When the paper residue attached to it comes into contact with the air, it will form hardened agglomerates on the surface of the scraper chain plate, which is not easy to be removed. The thicker scraper chain plate causes the scraper chain plate to protrude into the air flotation tank than the normal length scraper chain plate, so that when the scraper chain plate pushes the paper pulp close to the slag return tank, it will The partitions of the slag return tank and the air flotation ...
