Production line used for drying coal slime

Abstract

The invention relates to a production line used for drying coal slime. The production line used for drying the coal slime is characterized by comprising a coal slime raw material repository, a scraper conveyor, a preparatory material storage bin, a coal slime drier, a coal dust gas dusting machine, a gas recycling device and a finished product repository, wherein the gas recycling device of the production line is additionally provided with a secondary dust removal device, namely, a cyclone dust collector; and a small number of fine coal dust still existing in an intake airflow is separated from the airflow under the action of an inert centrifugal force through the rotation of a worm wheel, is thrown to the inner wall of the shell of the cyclone dust collector, and finally falls into a recycling hopper of the cyclone dust collector. The secondary dust removal further guarantees the quality of the gas exhausted to the atmosphere and belongs to an extremely environment-friendly gas recycling device. The production line used for drying the coal slime has the advantages of low energy consumption, low noise, strong structure stability, high processing efficiency, low equipment cost, strong equipment adaptability, no material blockage phenomenon, few production faults, low manufacturing cost and resource economization.

Description

Technical field [0001] The invention relates to a material processing production line, in particular to a production line for drying coal slime. Background technique [0002] The drying treatment of coal slime is mainly to process wet coal slime with a moisture content of about 40% through hot air drying treatment into dry coal slime with a moisture content of less than 10%. Existing production lines for coal slime drying generally have high energy consumption, high noise, poor structural stability, low processing efficiency, high equipment costs, poor equipment adaptability, serious blockages, multiple production failures, high manufacturing costs, and waste of resources Serious and other shortcomings, these problems have greatly restricted the healthy and rapid development of the coal slime drying industry. They are not in line with the current green energy and sustainable development strategies advocated by the state, and they do not meet the goals of a conservation-oriented s...
