Problems solved by technology

This manual method seems to be outdated
The processing time is long, the processing is not clean, and it is easy for the pulp to accumulate on the scraper, thereby blocking the drain pipe, thereby affecting the operation of the pulp machine, and even causing shutdown accidents
At the same time, there is a potential safety hazard in this method, that is, when the pulp machine is running, the staff stays near the pulp machine for a long time, which is prone to safety accidents

Abstract

The invention relates to a method and a device for preventing upturning of a paper web on a pulp machine used in a pulping paper mill. The device is characterized in that a spraying device is additionally arranged at an upper web driving roller of the pulp machine; the spraying device is connected with an original spraying system pipeline of the pulp machine; the paper web of a pulp board is washed by a fan-shaped spray head by utilizing spray water, so that the paper web is washed and falls into a couch roll pool. According to the device and the used device disclosed by the invention, the upturning of the paper web generated when the pulp machine is started is eliminated to the maximum extent, so that the pulp machine operates stable, smooth operation of production is guaranteed, and the labor force is saved.

Description

technical field [0001] The invention relates to a method and a device for preventing paper web turning up of a pulp board machine in a pulp and paper mill. Background technique [0002] When the modern large-scale, medium and high-speed pulp machine is running, the pulp sheet has not yet formed a paper web, and the net driving roller pulls the pulp machine to the Internet, and the pulp lumps are easy to turn over to the guide roller along with the upper web, accumulate on the scraper, and block the drain pipe , leading to downtime, cleaning the Internet. [0003] The way in the prior art is that when the pulp board machine is started up, the headbox has not yet supplied pulp, and the pulp board has not yet formed a paper web. At this time, on the high-level operating platform near the net drive roller of the pulp machine, two staff members are sent to stand on the transmission side and the operation side platform with clean water flushing pipes to wash the net drive roller ...
