Phenol residue pretreatment equipment

The phenol residue pretreatment equipment comprises a mixing assembly, and the mixing assembly comprises a driving motor, a supporting frame, two electric telescopic rods, a stirring rod, a sliding sleeve, a rotating shaft, two limiting rods, a push disc, four limiting blocks, a tension spring, a limiting ring, a rotating disc, four limiting grooves and an annular groove. And the top end of the rotating shaft is fixedly connected to an output shaft of a driving motor. According to the phenol residual oil and formaldehyde reagent stirring device, the driving motor drives the rotating shaft, the stirring rod stirs phenol residual oil and a formaldehyde reagent, the electric telescopic rod pushes the push disc and the rotating disc to drive the sliding sleeve, the sliding sleeve drives the stirring rod to move downwards, when the electric telescopic rod is reset, the sliding sleeve is reset under pulling of the tension spring, and then the stirring rod can move in a reciprocating mode. And through the up-down re
