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 a main pipe body of a hot air conveying pipe of the coal slime drier of the production line is made of a steel plate, so that pressure bearing intensity of the pipe body is guaranteed; a front explosion-proof port and a rear explosion-proof port are arranged at the front and rear ends of the main pipe body, so that equipment damage caused by over-pressure in the pipeline is avoided; and the inner wall of the main pipe body is provided with a spiral groove which extends along an air blowing direction, so that the flow speed of the hot air is speeded up, and drying efficiency is increased. 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 coal slime drying. 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. Existing production lines for coal slime drying 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 waste of resources Serious and other shortcomings, these problems greatly limit the healthy and rapid development of the 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.
