Chemical raw material treatment device

In order to solve the technical problems, a chemical raw material treatment device comprises a separation sieve plate mounted in a treatment box and is characterized in that the separation sieve plate is mounted and fixed to a rotating shaft, the rotating shaft is rotationally mounted on the treatment box, a feeding opening and a coarse material discharging opening are formed in the treatment box, a mounting seat is mounted and fixed to the treatment box, a pushing plate is mounted and fixed to the rotating shaft, a first arc spring is mounted and fixed to the pushing plate, the pushing plate is rotationally mounted in the mounting seat, and an extrusion plate is glidingly mounted in the treatment box. To-be-discharged raw materials are received firstly, then the extrusion plate is driven by a moving device to extrude the materials, in the extrusion process, the sieve plate cannot rotate, the extrusion effect is improved, the limitation on the sieve plate is removed when the extrusion plate moves back, the si
