However, this operation may cause the following problems. In the process of inputting the polyaluminium chloride slurry into the reactor body through a feeding pipe, since the slurry mixed with aluminium hydroxide powder and hydrochloric acid is very thick, it is easy to cause blockage at the feeding pipe, affecting the feeding efficiency, and thus resulting in low production efficiency. By setting an adjusting structure, the polyaluminium chloride slurry is injected into the cylinder through the input pipe, the servo motor is started, the servo motor drives the adjusting cylinder to rotate, and the adjusting cylinder drives the slide by the inner wall of the slide groove.
