[0036] Working principle:

[0037] When the automatic quantitative refractory material feeding device is actually used, the operator pulls out the sealing cover 31, and adds refractory material to the inside of the feed hopper 2 through the penetration of the sealing cover 31. When the amount of refractory material added reaches the preset value of the weight sensor 3, a signal is sent to the controller, and the controller can open and close the electric gate valve 5, and at the same time, the fan 10, the air pump 18 and the drive motor 19 are activated. The refractory material can enter the inside of the feed pipe 7 through the electric gate valve 5, the telescopic hose 9 and the feed pipe 8. The fan 10 works to draw air into the inside of the feed pipe 7, and this part of the air can push the refractory material inside the feed pipe 7. The driving motor 19 works, and its output end can drive the main gear 20 to rotate. Since the main gear 20 and the driven gear 21 are meshed with each other, the rotating main gear 20 can drive the driven gear 21 to rotate, and the rotating driven gear 21 can drive the shaft tube 16 to rotate, and the shaft tube 16 can drive the air storage plate 12 to rotate. The air pump 18 works and can draw air into the interior of the air storage plate 12 through the connecting pipe 22 and the shaft tube 16. The air inside the air storage plate 12 can be ejected through the multiple groups of injection pipes 14. The multiple groups of second one-way valves 15 can prevent the refractory materials inside the feed hopper 2 from entering the air storage plate 12 through the multiple groups of injection pipes 14. 2, the first one-way valve 11 can prevent the refractory material in the feeding pipe 7 from entering the inside of the fan 10, and the refractory material contaminated on the surface of the gas storage plate 12, the multiple groups of jet pipes 14 and the multiple groups of second one-way valves 15 will be separated by centrifugal force. The gas storage plate 12 can be used to conveniently remove the adsorbed refractory material inside the hopper structure, which is convenient for cleaning the automatic quantitative refractory material feeding device. At the same time, according to the above operation, it can be known that the fan 10 can draw air into the inside of the feeding pipe 7. When there is foreign matter contacting the filter screen 13, the foreign matter will prevent the air from passing through the fan 10 into the feeding pipe. Inside the material pipe 7, foreign objects will drive the fixed pipe 26 and the movable orifice plate 25 to move through the filter screen 13. During this process, the movable orifice plate 25 and the mounting orifice plate 24 can squeeze multiple sets of telescopic springs 27. When the movable orifice plate 25 presses the push switch 28, the buzzer alarm 29 starts to work. The operator can know whether there is foreign object moving toward the fan 10 through the sound emitted by the buzzer alarm 29. The filter screen 13 is provided with a prompt structure, and the operator can know in time whether the feeding work is terminated, which brings a guarantee for the continuous use of the automatic quantitative refractory material feeding device.
