A bleaching device for paper product processing

Abstract

The invention discloses a bleaching plant for converting paper. The bleaching plant comprises a bleaching pond and a draining pond, a filter screen is embedded and sleeved on the bottom end face of an inner cavity of the draining pond, a support plate is installed on the edge of the top end of the draining pond, a first electric hydraulic push rod, a second electric hydraulic push rod, a third electric hydraulic push rod and a fourth electric hydraulic push rod are respectively fixedly connected in inner cavities of a first placement groove, a second placement groove, a third placement groove and a fourth placement groove in an inserted manner, a first support beam is fixedly connected between the top end of the first electric hydraulic push rod and the top end of the second electric hydraulic push rod, a second support beam is fixedly connected between the top end of the third electric hydraulic push rod and the top end of the fourth electric hydraulic push rod, a processor is fixedly installed at the bottom end of an inner cavity of the bleaching pond, and the right side of the processor is electrically connected with a controller through a wire. The bleaching plant reduces the labor force of a worker, and the paper pulp and a bleaching agent are fully contacted through the vertical lifting of the draining pond, so that the paper pulp is thoroughly bleached.

Description

technical field [0001] The invention relates to the technical field of paper product processing and application, in particular to a bleaching device for paper product processing. Background technique [0002] At present, in the domestic market, the bleaching process of traditional bleaching agents such as hydrogen peroxide and hypochlorite is generally used in the bleaching of office waste paper pulp. The bleaching rate is low, and more toxic substances are produced during the bleaching process, which can absorb organic chlorides. Therefore, the existing domestic waste paper pulp bleaching technology can only produce low-grade waste paper bleaching, which limits the application range of waste paper. Now foreign research shows that, The bleaching technology using oxygen and ozone as the main bleaching agent has major problems such as low product rate, large fiber damage, huge equipment investment, cumbersome process, high production cost, and difficult control of product qual...

Problems solved by technology

[0002] At present, in the domestic market, the bleaching process of traditional bleaching agents such as hydrogen peroxide and hypochlorite is generally used in the bleaching of office waste paper pulp. The bleaching rate is low, and more toxic substances are produced during the bleaching process, which can absorb organic chlorides. Therefore, the existing domestic waste paper pulp bleaching technology can only produce low-grade waste paper bleaching, which limits the application range of waste paper. Now foreign research shows that, The bleaching technology using oxygen and ozone as the main bleaching agent has major problems such as low product rate, large fiber damage, huge equipment investment, cumbersome process, high production cost, and difficult control of product quality. Therefore, it has not been widely used at present. , and during the bleaching process, the pulp is mostly mixed together, and it is not easy to fully contact with the bleaching agent, making the bleaching incomplete. Moreover, after bleaching, it is necessary to fish the bleached pulp, drain the bleaching agent, and enter the next processing procedure ,, In the process of fishing, a lot of labor is wasted, time-consuming and labor-intensive, so a bleaching device for paper product processing is designed and produced here, which can not only ensure its beautiful appearance, but also meet the needs of processing
