The raw material polyether of polyurethane and isophorone diisocyanate are evenly mixed and then react with a proper amount of hydrophilic chain extender, chain extender diethylene glycol, a proper amount of acetone and catalyst in a reaction kettle, after the reaction is finished, a small amount of polyurethane resin products and some organic impurities can be remained in the synthesis kettle, if the impurities attached to the wall of the synthesis kettle cannot be cleaned in time, the quality of subsequent synthesis products can be influenced, the macromolecular waterborne polyurethane polymer attached to the inner wall of the reaction kettle needs to be cleaned, and the cleaned raw material polyether is conveyed to a wastewater treatment device for treatment. Meanwhile, the waste water after washing of packaging barrels, pulling cylinders and the like for turnover; the waste water generated by ground washing also needs to be sent to a sewage treatment device for treatment.
SUMMERY OF THE UTILITY MODEL
The utility model provides a waterborne polyurethane sewage treatment recovery unit to the synthetic cauldron of polyurethane that solves the prior art existence washs the problem that produces waste water treatment and retrieve.
The utility model provides a technical scheme that its technical problem adopted is:
a water-based polyurethane sewage treatment and recovery device comprises a sewage collecting tank, a sewage pump, a stirring tank, a stirrer, a speed reducer, a stirring motor, a collecting pit, a feeding pump, a filter press, a pressure filtration pump, a water storage tank and a clean water tank.
