Chemical sewage treatment equipment

The invention relates to the field of sewage treatment, in particular to chemical sewage treatment equipment. The blow-off pipe is horizontally arranged, and a discharge hole is formed in the blow-off pipe. And a cavity between the material collecting shell and the pipeline is a material collecting cavity, so that garbage in the blow-off pipe enters the material collecting cavity through the discharge hole. When the material blocking plate is pushed outwards by the garbage in the blow-off pipe, the garbage pushes the material blocking plate to be opened. The fixing shaft is horizontally arranged in the blow-off pipe and is coaxial with the blow-off pipe, one end of the fixing shaft is fixedly connected with the fixing frame, and the other end of the fixing shaft extends towards the water inlet end in the axial direction; the filter screen is in a conical shape and is slidably arranged on the fixing shaft in a sleeving mode, and the flaring end is located at one end of the water outlet so that garbage can be a
