Coal slurry-drying production line

Abstract

The invention relates to a coal slurry-drying production line. The coal slurry-drying production line is characterized in that the coal slurry-drying production line comprises a coal slurry storage silo, a scraper conveyer, a preparatory bin, a coal slurry dryer, a coal dust gas deduster, a gas-recycling unit and a finished product storage silo. Because a retractable discharge hopper unit in the production line adopts a retractable hopper design, flying dust in discharge can be effectively reduced; as retractable shells are extended or retracted, a retractable sleeve is extended or retracted, and thereby flying dust can be further prevented from leaking out; and a guiding track can control the moving track of the retractable shells to prevent the deflection of the retractable shells, thus further guaranteeing the accuracy of the discharge position. The coal slurry-drying production line has the advantages of low energy consumption, little noise, high structural stability, high processing efficiency, low equipment cost, high equipment adaptability, no blockage, less production failure, low production cost and resource saving.

Description

technical field [0001] The invention relates to a material processing production line, in particular to a coal slime drying treatment production line. Background technique [0002] The drying treatment of coal slime is mainly to process the wet coal slime with a moisture content of about 40% into dry coal slime with a moisture content of less than 10% through hot air drying. The existing coal slime drying treatment production lines generally have high energy consumption, high noise, poor structural stability, low processing efficiency, high equipment cost, poor equipment adaptability, serious material blocking, many production failures, high manufacturing costs, and serious waste of resources, etc. Disadvantages, these problems have greatly restricted the healthy and rapid development of the slime drying industry, which is not in line with the current national strategy of green energy and sustainable development, nor in line with the goal of a conservation-oriented society. ...

AI Technical Summary

Problems solved by technology

The existing coal slime drying treatment production lines generally have high energy consumption, high noise, poor structural stability, low processing efficiency, high equipment cost, poor equipment adaptability, serious material blocking, many production failures, high manufacturing costs, and serious waste of resources, etc. Disadvantages, these problems greatly limit the healthy and rapid development of the coal slime drying industry, which does not conform to the current strategy of green energy and sustainable development advocated by the state, nor does it conform to the goal of a conservation-oriented society
