毎に人手により除去するようにしている。この除去方法
は、一般にドラムＤの幅に届く長さのホースを備えた電
気掃除機で紙粉を除去する方法が採用されていた。When the drum D is operated continuously for a long period of time, a large amount of paper powder stripped off by the doctor blade DB accumulates on the upper part of the doctor blade DI+, so in the past, the paper powder was manually removed at regular intervals. There is. This removal method generally involves removing paper dust using a vacuum cleaner equipped with a hose that is long enough to reach the width of the drum D.
ところで、上述した抄紙機内のドライヤイ」近は、ドラ
イヤのドラム内に送り込まれる電気による紙の乾燥のた
めに高温多湿であり、作業環境としては極めて厳しい環
境にある。By the way, the area near the dryer in the paper machine described above is hot and humid due to the electricity fed into the drum of the dryer to dry the paper, making it an extremely harsh working environment.
従って、このような厳しい作業条件のもとてドライヤの
ドラムに付着堆積する紙粉を電気掃除機により除去する
従来の方法では、紙粉が飛散してドライヤの周辺機器に
付着し作業環境が粉塵のため悪くなり、飛散した紙粉を
集塵するのが困難で、かつ作業性が悪く、悪条件の環境
下で作業員を配置しなければならないという問題があっ
た。Therefore, in the conventional method of using a vacuum cleaner to remove the paper dust that accumulates on the drum of the dryer under such harsh working conditions, the paper dust scatters and adheres to the peripheral equipment of the dryer, creating a dusty work environment. There were problems in that it was difficult to collect the scattered paper powder, the workability was poor, and workers had to be placed under adverse conditions.
また、堆積した紙粉を完全に除去できないため、この紙
粉が飛散、落下して紙層Ｗに付着し、不良な製品が生産
されてしまうという問題もあった。Further, since the accumulated paper powder cannot be completely removed, there is a problem in that the paper powder scatters, falls, and adheres to the paper layer W, resulting in the production of defective products.
この発明は、か−る従来の抄紙機のドライヤに付着する
紙粉を除去する技術の現状に鑑みてなされたものであり
、その第一の目的はドクタブレー１゛の周囲を遮蔽部で
囲むことによって紙粉の飛散を防止し集められた紙粉を
吸引処理自在とした紙粉除去装置を提供するにある。This invention was made in view of the current state of technology for removing paper dust adhering to the dryer of the conventional paper machine, and its first purpose is to surround the doctor blade 1 with a shielding part. To provide a paper dust removing device which prevents paper dust from scattering and can freely suction and process the collected paper dust.
第二の目的は上記紙粉除去装置に対して集塵装置を備え
、紙粉除去作用を自動化した紙粉除去装置を提供するに
ある。A second object is to provide a paper dust removing apparatus which is equipped with a dust collector in addition to the above paper dust removing apparatus, and which automates the paper dust removing action.
