[0021] According to the instruction manual Figures 1-4It can be known that the utility model discloses a valve is closed on the discharge port 17 during working, and the valve is designed as prior art. Water is injected into the box 2 through the water inlet pipe, and the total amount of water injection is according to the proportion of the firebrick raw material. Here, continuous water supply can be selected, or water can be injected at one time. The motor 18 is started, the output end of the motor 18 drives the rotating shaft 16 to rotate, thereby driving the stirring blade 3 and the scraper 13 to rotate. Personnel put the firebrick dry raw material into the feeding hopper 9 through external feeding equipment or manually. The raw material enters the box 2 from the feeding port 10 and falls on the deflector 6. The rotation of the rotating shaft 16 also drives the scraper 13 to rotate. Since the bottom surface of the scraper 13 is in sliding contact with the upper surface of the deflector 6, and the outer end is in sliding contact with the inner wall of the box 2, the scraper 13 drives the raw material on the deflector 6 to rotate. Since a plurality of material holes 14 are uniformly arranged on the deflector 6, under the action of the scraper 13, the raw material falls from different material holes 14 into the water at the bottom of the box 2, so that the raw material falls from different positions and is uniformly scattered.
