[0002] The reactor is a kind of equipment widely used in laboratories and industrial production, such as in the preparation and production of hot melt adhesives; it is mainly composed of reaction vessels, heating, cooling, stirring, pressure control and other systems.

[0003] When the reactor is opening or closing the manhole cover, there is a large amount of chemical gas in the reactor, and gas will flow out from the manhole during operation, which will endanger the health of the operator and pollute the environment. For example, a Chinese patent for a reactor exhaust device (publication number: CN205517685U) uses a motor to extract the leaked gas, eliminating the safety hazards to the operator and the environment. At the same time, the rotating device is set on the transmission bracket to facilitate feeding and maintenance. However, in this structure, the guide hood is a distance away from the reactor mouth, which results in a poor exhaust effect and cannot effectively extract the gas in the reactor body.
