[0001] The invention relates to the technical field of building material metallurgy, in particular to a kiln head feeding device capable of accurately controlling the feeding amount. Background Art

[0002] In the high-end production lines of factories in the building materials, metallurgy and other industries, the kiln has high requirements on the accuracy of the batch material delivery. When the batch material is difficult to melt, the kiln has very high accuracy requirements on the amount of batch material entering the kiln. If there is too much batch material entering the kiln, the kiln cannot melt it, and the finished glass is prone to defects. In addition, too high a liquid level will affect the safety of the kiln and the kiln load will be too large, which will have a great impact on the life of the melting furnace. If there is too little batch material entering the kiln, the kiln will burn dry and waste energy, and the melting will easily fluctuate. The refractory materials of the kiln will be overheated, which will have a great impact on the life of the melting furnace. Therefore, it is necessary to control the amount of batch material entering the kiln according to the liquid level of the kiln in real time and accurately measure the amount of batch material entering the kiln.
