Device for pulverizing and distribution transferring for coal

Abstract

The present invention relates to a device for pulverizing and distribution transferring for coal. More specifically, in the process of manufacturing pulverized coal by pulverizing coal, moisture contained in the coal is dried and foreign substances contained in the coal is removed simultaneously with sucking nitrogen gas supplied during operations such as the drying or the like so as to discharge the nitrogen gas. Therefore, the device for pulverizing and distribution transferring for coal may manufacture high quality pulverized coal. In order to achieve the object, the present invention is characterized by comprising: a first crushing section for crushing coal, which is supplied from the outside; a conveying section for conveying the coal, which is crushed in the first crushing section; a second crushing section for crushing the coal, which is conveyed via the conveying section; a drying section for drying the coal, which is crushed in the second crushing section; a pulverizing section for pulverizing the coal, which is dried in the drying section; and a discharge section for discharging the pulverized coal, which is pulverized in the pulverizing section.

Description

technical field [0001] The present invention relates to a coal pulverizing, distributing and transferring device, and more particularly, to a method for drying the moisture contained in the coal during the process of pulverizing coal and making it into micropowder, removing the impurities contained in the coal, and simultaneously sucking the coal into the fine powder. A coal crushing, distribution and transfer device that produces high-quality micro-powdered coal by removing the gas generated during operations such as drying and discharging it to the outside. Background technique [0002] Generally, the micronized carbon manufacturing and taking-in operation process in the micronized carbon equipment are as follows: figure 1 shown, the following will refer to figure 1 Give a brief description. [0003] That is, the coal conveyed from the coal yard by the conveyor belt is stored in the raw coal hopper (Raw Coal Hopper) 1 . The coal stored in the coal stocker 1 is supplied ...

AI Technical Summary

Problems solved by technology

[0010] However, in the conventional micro-powdered carbon manufacturing process, the exhaust gas used for transporting the micro-powdered carbon is released into the atmosphere, which causes environmental problems. In addition, the coal containing a large amount of moisture is directly transferred to the crusher 3, and the temperature in the crusher 3 Changes with the moisture content of the coal, resulting in unstable hot air control
