Description

Device for conveying carbon black into coal mill Technical Field The utility model relates to the technical field of carbon black conveying equipment, in particular to a device for conveying carbon black into a coal mill. Background Coal grinding is equipment for grinding massive coal into pulverized coal, and is widely used in the industries of electric power, chemical industry and the like. The coal particles are reduced by mechanical forces such as extrusion, grinding and the like, so that the coal can react more efficiently in combustion or other processes. Carbon black is amorphous carbon and is produced by incomplete combustion or thermal cracking of hydrocarbons. It has small particle size, large specific surface area and strong adsorptivity, is an important additive in rubber, plastics and other industries, can greatly improve the product performance, such as enhancing the wear resistance of rubber and enhancing the ultraviolet resistance of plastic products. In the cement industry, carbon black and coal are mixed. For example, when part of fuel is prepared, the addition of a proper amount of carbon black can enable coal to burn more fully, improve the energy utilization rate and reduce pollutant emission. The mixture of coal and carbon black after coal grinding can provide special carbon source and structural characteristics, and chemical products with special performance are synthesized by assistance, so that the conveying of carbon black to the coal grinding is significant for optimizing the process and improving the quality of products. However, the current way of delivering carbon black to the mill is not adequate. The existing equipment cannot effectively dry the carbon black, the carbon black is easy to absorb water, and excessive water enters the coal mill, so that the grinding efficiency is reduced, the energy consumption is increased, the mixture is agglomerated in the subsequent process, and the product quality is affected. In addition, the existing conveying is difficult to break carbon black agglomerates, the agglomerates enter a coal mill, the advantages of carbon black cannot be exerted, equipment is worn, the quality of products fluctuates, and strict industrial standards are difficult to achieve.
