Embodiment Construction

[0012] The technical process of the present invention and the specific structure of the equipment used are described in detail according to accompanying drawings 1-4.

[0013] The technological process of the invention is crushing→collecting→premixing→homogenizing→storage. Among them, the pulverizing process adopts a pulverizer 1 with multi-stage crushing and optional functions. The collection process adopts a dust collector 2 composed of a cyclone dust collector 14 , a bag dust collector 15 and a feeding device 16 connected to each other. The mixing process adopts a premix mixing tank 3 and a homogeneous mixing colloid mill 4 with an agitator 17 . A dust collector 2 is provided between the pulverizer 1 and the mixing tank 3 . Coal pulverizer 1 (patent applied for separately) comprises the lower body 13 that is assembled with bearing block 6, the upper body 8 that has feeding hopper 7 and parts such as transmission shaft 12, hammer plate, fan 11 that assemble in it. Wherein...

Abstract

The production process of coal water fluid includes decontaminating material, crushing, collecting, mixing and fluid storing. There are one crushing machine with right and left hammer tray and several stages of crushing and selecting unit used during crushing, one pre-mixing tank with stirrer and one mixing colloid mill used in mixing, and one dust collector set between coal crushing machine and mixing tank. The production process has the features of low equipment producing cost, small covered area, short technological path, less noise, and no dust pollution. The present invention results in improved product quality and improved environment.

Description

technical field [0001] The invention relates to a method for preparing coal-water slurry. The crushing equipment used is also suitable for crushing talc, kaolin, graphite and other materials, and is also suitable for crushing various fuels, dyes, Chinese herbal medicines and the like. Background technique [0002] At present, there are many pulping methods for preparing coal-water slurry, but they are generally limited to use in large-scale pulping processes and are not suitable for use in small-scale pulping processes. Especially among the existing fuels, coal-water slurry, as a new type of energy-saving and environment-friendly fuel, has become an ideal substitute product for raw coal, heavy oil and other fuels, and has been widely promoted and applied. Therefore, the country has taken this technology as a key development project. In the existing large-scale pulping process such as crushing, mixing, and slurry storage of coal-water slurry produced at home and abroad, the ...
