[0002] Coal chemical wastewater refers to the wastewater generated during the processing and utilization of coal. The characteristics of coal chemical wastewater include: high concentration of suspended solids, high concentration of organic matter, high concentration of nutrients containing nitrogen, phosphorus and other elements, and usually also contains heavy metals, arsenic, cyanide and other toxic substances. Therefore, coal chemical wastewater needs to be treated and processed by special wastewater treatment equipment before it can be subsequently treated or discharged.

[0003] After searching, the existing Chinese patent announcement number is: CN212559745U, which provides a coal chemical wastewater treatment device, which drives the fixed shaft to rotate by starting the motor to drive the stirring plate to rotate, thereby accelerating the fusion of the drug and the coal chemical wastewater, and a scraper is provided on the stirring plate to prevent some of the reacted substances from adhering to the inner wall of the reactor. However, although the coal chemical wastewater treatment device can well achieve the treatment of coal chemical wastewater, due to its integrated reactor design and the large amount of dirt in the coal chemical wastewater, it is easy to adhere to the components inside the reactor. Therefore, there are still problems such as the difficulty in disassembly, inspection and cleaning of the device, and inconvenience in repair and maintenance.

[0004] In view of this, how to provide a coal chemical wastewater treatment device that is easy to disassemble, overhaul, clean and maintain has become one of the technical problems that need to be solved urgently in this field. Utility Model Content
