Experiment refers to one of the basic methods of scientific research. A reactor is broadly understood as a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are achieved. Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine, food, etc., and are generally made of carbon-manganese steel, stainless steel and other composite materials.

The utility model device can extract the reaction liquid in the reactor into the liquid storage tank by means of a water pump and a filter head, and can achieve solid-liquid separation during solid-liquid reaction, solving the problem that the reactants are mixed together and the reaction process cannot be terminated and the reaction cannot be controlled. However, the technology is consistent with the traditional method in that: the traditional technology In the process, an inspection cover is installed on the top of the reactor, and the inspection cover is connected to the top of the reactor through a flange, and the connection is fixed by bolts.

Therefore, the connection design of the inspection cover on the top of the reactor in traditional technology has serious safety hazards, and improvements need to be made in sealing performance and connection methods to improve the safety and stability of experimental operations.
