Thereby preventing the slurry from submerging the nozzle 5 and contaminating or plugging the nozzle 5. The stirring system 6 comprises a stirring shaft, and stirring blades are arranged on the stirring shaft. The material outlet is positioned on the side wall of the lower part of the tank body. Preferably, the height of the material outlet is equal to the height of the stirring blade located at the lowest position. Therefore, under the centrifugal force of the stirring blades, the materials are more easily discharged from the tank body. The preferred connecting cylinder that includes of spray system, the connecting cylinder is including being pipy inner tube, being pipy outer tube, connecting at the top of top end capping, connecting at the bottom end capping of bottom, and inner tube, outer tube, top end capping, bottom end capping enclose into a well cavity, are fixed with nozzle 5 on the end capping of bottom, and the passageway and the well cavity UNICOM of nozzle 5 interior have the inlet on the top end capping, and the inlet passes through the delivery port of third pipe connection pump. The bottom end of the connecting cylinder is fixed on the top of the tank body. The top of the tank body is provided with a nozzle insertion hole, and the nozzle 5 passes through the nozzle insertion hole and extends into the tank body. At least four nozzles 5 are arranged, and the nozzles 5 are arranged at equal intervals. Thereby facilitating the arrangement of the stirring shaft and reducing the mutual influence between the stirring shaft and the nozzle 5. Further preferably, the stirring system 6 further comprises a driving motor, the driving motor is connected with the stirring shaft through a coupler, and the lower part of the driving motor is inserted into the inner pipe. Thereby utilize the spacing driving motor of inner tube, reduce driving motor's noise simultaneously.
