Abstract

The invention provides a coal slime indirect drying system. The coal slime indirect drying system comprises a first conveyor, a blender mixer, a feeding machine, a dryer and a second conveyor. The output end of the first conveyor is connected with the first input end of the blender mixer. The output end of the blender mixer is connected with the feeding end of the dryer through the feeding machine. The discharging end of the dryer is connected with the input end of the second conveyor. The first output end of the second conveyor is connected with the second input end of the blender mixer. Thesecond output end of the blender mixer is used for outputting dried coal slime. The blender mixer is used for mixing the coal slime provided by the first conveyor and the second conveyor and conveyingthe coal slime to the dryer through the feeding machine. The dryer can make the coal slime slowly overturn, and meanwhile, the coal slime is heated and dried indirectly by using steam. By means of the coal slime indirect drying system, the environmental pollution in the drying process can be reduced, the drying efficiency is improved, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the field of drying and upgrading coal materials, and in particular relates to an indirect drying system for coal slime. Background technique [0002] Viscous by-products such as coal slime are often produced during the coal washing process. At present, the annual output of coal slime in my country exceeds 250 million tons, which is a huge output. Coal slime contains a large amount of combustible components, has a high calorific value, and is worthy of comprehensive utilization. In addition, if the coal slime is not utilized and allowed to be stacked in the open air, it will cause extremely serious pollution to the environment. However, coal slime has the characteristics of high water content, high viscosity, easy agglomeration, easy bonding, and discontinuous discharge. As a result, it often brings many problems to the production system during transportation and storage, and the utilization rate of heat energy is low. Affec...
