Problems solved by technology

[0002] The observation window of the existing air hood of the paper machine has a rectangular structure, such as figure 1 As shown, the gas hood 1 cannot timely evacuate the water vapor at the right angle of the rectangular observation window 2
Especially when the temperature difference is large in winter, due to the large temperature difference inside and outside the gas hood at the observation window of the gas hood, a large amount of water vapor will generate condensed water on the inner wall of the gas hood, gather at the bottom of the observation window of the gas hood, and will drip on the paper surface of the dryer, directly Cause water holes on the paper, produce a large number of substandard products, directly increase production consumption

Embodiment 1

[0016] Such as figure 2 As shown, a paper machine gas hood observation window includes an observation window 2, and an air hood 1 connected to the observation window, and also includes a stainless steel plate 3, and the stainless steel plate 3 is welded inside the observation window 2, and is connected to the observation window 2 The bottom is inclined, and the size of the stainless steel plate is 450mm×350mm.

[0017] The water vapor at the observation window can be evacuated by the gas hood in time to avoid causing a large amount of steam to meet the observation window to form condensed water, and there will be no dripping phenomenon to ensure that the product is qualified.

Abstract

The invention relates to an observation window for a gas hood of a paper machine, comprising an observation window, a gas hood connected with the observation window, and a stainless steel plate, wherein the stainless steel plate is arranged in the observation window, and forms a slope together with the bottom of the observation window. Compared with the prior art, the observation window has the advantages that the operation is convenient, the safety and the reliability are realized, the quality is improved, and the like.

Description

technical field [0001] The invention relates to a paper machine, in particular to an observation window of an air cover of a paper machine. Background technique [0002] The observation window of the existing air hood of the paper machine has a rectangular structure, such as figure 1 As shown, the gas shield 1 cannot in time evacuate the water vapor at the right angle of the rectangular observation window 2. Especially when the temperature difference is large in winter, due to the large temperature difference inside and outside the gas hood at the observation window of the gas hood, a large amount of water vapor will generate condensed water on the inner wall of the gas hood, gather at the bottom of the observation window of the gas hood, and will drip on the paper surface of the dryer, directly Cause water holes on the paper, produce a large number of unqualified products, directly increase production consumption. Contents of the invention [0003] The purpose of the pr...
