The invention discloses a
wastewater precipitating and recycling device for building decoration
engineering. The
wastewater precipitating and recycling device comprises a body, a
wastewater inlet, anaeration pump, a deslagging mechanism and a liquid outlet, wherein the top end of the body is provided with the wastewater inlet; the deslagging mechanism is fixedly arranged at the bottom part of thebody; the deslagging mechanism comprises a screw rod, a motor, a sliding block, a
slag scraping plate and a sliding rod; the screw rod is rotationally connected to the bottom end of the body throughbearing seats arranged on two ends; one end of the screw rod stretches to the outer side of the body, and a first belt wheel is fixedly arranged on the stretching end of the screw rod; a second belt wheel is fixedly arranged at the end part of an output shaft of the motor; two sides of the bottom end of the body are provided with
slag outlets; the position above the deslagging mechanism, of the side surface of the body is fixedly provided with the liquid outlet.. The deslagging mechanism is fixedly arranged on the bottom end of the body and the
slag scraping plate is driven to do reciprocatingmotion through the motor, so that a removing process of slag materials on the bottom end of the inner part of the body can be completed, the operation is simple and convenient, the continuous using performance of the wastewater precipitating and recycling device is improved, and economy and practicability are achieved.
