Description

Technical Field

[0001] The utility model relates to the field of chemical reaction devices, in particular to an installation structure of a reaction kettle sight glass. Background Art

[0002] Glass sight glasses are an indispensable part of chemical container equipment. In reactor equipment, the reaction and changes of materials in the reactor can be observed through glass sight glasses, and the level of materials in the reactor can also be observed. However, during the production process, there are often certain factors that cause oxides to adhere to the surface of the glass sight glasses. When the oxides adhere to a certain degree, the sight glasses will become blurred, and production personnel will not be able to observe the various conditions in the reactor through the sight glasses. Therefore, it is necessary to replace the blurred sight glasses.

[0003] During the replacement of the sight glass, the reactor is in a high temperature state, with a large amount of steam and caprolactam gas, which will seriously interfere with the operator's vision. If the operator is exposed to caprolactam gas for a long time, it will cause certain harm to the human body. The installation structure of the reactor sight glass in the prior art, the operation process of replacing the sight glass is as follows: remove the sight glass fixing bolts and nuts → remove the sight glass glass gland flange → remove the sight glass → remove the old sealing gasket → install the lower flange sealing gasket → install the trial mirror → install the upper flange sealing gasket → insert the upper flange → tighten all screws and nuts. The replacement process is complicated, and in the process of replacing the sight glass, it is necessary to press the sight glass by hand to prevent the gas in the reactor from pushing the sight glass out. When the flange gasket is placed, the hand must be taken away from the sight glass to put in the gasket. At this moment, the sight glass loses its constraint, and the sight glass will be pushed out by the gas in the tank, resulting in the dislocation of the sight glass, which is easy to cause damage to the sight glass. The sight glass needs to be re-placed, and as the temperature in the tank is transmitted to the sight glass, the sight glass becomes hot and more difficult to install, resulting in an increase in working time and affecting product quality.
