Anti-blocking scraper blade mechanism of hot air box

Abstract

The invention relates to a dust collection device of a hot air box on a dry method paper production line, in particular to an anti-blocking scraper blade mechanism of the hot air box. The anti-blocking scraper blade mechanism of the hot air box comprises steel wire ropes, an upper scraper blade, a lower scraper blade, guide wheels, a driving wheel and a driving motor, wherein the guide wheels, the driving wheel and the driving motor are arranged at the outer side of the hot air box; the driving wheel is connected with the output end of the driving motor; the guide wheels are multiple, and are respectively distributed at corresponding positions of both ends of an upper layer air uniform plate and a lower layer air uniform plate in the hot air box; the steel wire ropes are distributed at both sides of the upper layer air uniform plate and the lower layer air uniform plate, and pass through the guide wheels to be connected with the driving wheel; the upper scraper blade and the lower scraper blade are respectively arranged above the upper layer air uniform plate and the lower layer air uniform plate, and both ends of the upper scraper blade and both ends of the lower scraper blade are connected with the steel wire ropes; the upper scraper blade and the lower scraper blade do reciprocating motion through the driving of the steel wire ropes to scrape off dust on the upper layer air uniform plate and the lower layer air uniform plate. According to the dust collection device provided by the invention, the dust accumulated on the air uniform plates is scraped off in time so as to achieve the goal that holes are not blocked.

Description

technical field [0001] The invention relates to a dust removal device for a hot air box on an air-laid paper production line, in particular to a hot air box anti-blocking scraper mechanism. Background technique [0002] The air-laid paper production line is equipped with a hot air box. The function of the hot air box is to send heated air to the paper surface mesh belt to heat and dry the air-laid paper to form finished paper. Because the incoming hot air is relatively large and unevenly distributed, the unheated paper web can be blown away and deformed, and the paper cannot even enter the hot air box. Therefore, upper and lower layers of air equalizers are arranged on the upper part of the hot air box to evenly enter the hot air while reducing the intensity of the wind so that the paper can smoothly enter the hot air box without being blown away or deformed. However, due to the circulating hot air with dust, the dust will block the holes of the air uniform plate, resulting...
