[0038] When in use, the device is pushed to the bottom of the concrete mixing station discharge bin, and then the water outlet end of the pump 8 is connected to the concrete mixing station discharge bin through a pipeline. Then, in the process of cleaning the mixing station, waste water and waste materials fall into the feed hopper 3 and enter the inner side of the conveying chamber 4, and are intercepted by the interception plate 1 601 and the interception plate 2 602.
