Silica removal device for treating wastewater in coal chemical industry and treatment process

The invention discloses a silicon removal device for treating wastewater in the coal chemical industry and a treatment process, and relates to the technical field of wastewater silicon removal, the silicon removal device comprises a throwing cylinder, a shell is rotatably connected to the outer surface of the throwing cylinder, a drainage groove is formed in the side wall of the throwing cylinder located in the shell, and a filter plate is fixedly connected in the drainage groove; and a strip-shaped electromagnetic block is fixedly connected to the filter plate. Through cooperative arrangement of the rotating mechanism, the throwing cylinder and the filter plate, the functions of rapidly filtering out flocculate and dewatering the flocculate can be achieved, then through cooperative arrangement of the first pressing plate and the second pressing plate, the flocculate can be extruded and dewatered, and the dewatering effect is further improved; flocculate is influenced by gravity, more flocculate is accumulate
