[0002] Chlorosilane is a chemical that can react violently with compounds containing active hydrogen. In the synthesis of chlorosilane, a reaction device is required to mix the required raw materials and catalysts and carry out the reaction in the reaction device.

[0003] For example, there is an efficient corrosion-resistant reactor with a publication number of CN217549782U, which includes a shell, a feed pipe, a discharge pipe, a motor, a screw, a cleaning assembly, etc. The device uses a cleaning assembly that can move up and down to flush the inner wall of the reactor, thereby cleaning the reactor to prevent residual chemical materials from corroding the reactor.
