Coal pulverizer with dustproof function

Abstract

The invention discloses a coal pulverizer with a dustproof function. The coal pulverizer comprises a pulverizer body, a motor, a crushing roller and a suction ventilator; a feeding port and a discharging port are arranged on the upper end and the lower end of the pulverizer body correspondingly; a discharging through port is reserved in the middle of the pulverizer body; the motor is embedded in the lower end of the interior of the pulverizer body; an extrusion block is arranged in a sliding groove; a rack is installed on one side of the extrusion block; a first gear is installed in the pulverizer body; a second gear is installed at one end of an adjusting column; a guide disc is in shaft connection with the interior of the upper end of the pulverizer body; a rotary disc is installed at one end of a rotary block; a rotary drum is in shaft connection with the interior of the upper end of the pulverizer body; and a movable block is located in a limiting groove. According to the coal pulverizer with the dustproof function provided by the invention, the situation that the pulverizing work efficiency is not high due to blockage caused by excessive coal can be avoided, and powder generated in the coal pulverizing process can be collected, so that the safety and usability of the device are improved.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to a coal pulverizer with dust-proof function. Background technique [0002] With the development of historical civilization and the technological progress of mankind, coal was found to be mined as a fuel, known as black gold, and food for industry. Although the important position of coal has been gradually replaced by oil, coal is still It is one of the irreplaceable energy sources in human production and life. Coal is evolved from ancient plant remains. The main elements in coal are carbon, hydrogen, oxygen, nitrogen and sulfur, accounting for more than 95%. It is the chemical fuel with the most abundant reserves and the widest geographical distribution. During the mining and processing of coal, coal needs to be pulverized. However, the existing coal pulverizers still have the following problems: [0003] 1. When crushing coal, a large amount of dust will inevitably be ge...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a coal pulverizer with a dust-proof function, to solve the existing coal pulverizers on the market proposed by the above-mentioned background technology, because too much coal is easy to cause blockage, so that the crushing work efficiency is not high, and A large amount of dust will inevitably be generated during crushing, and the existing pulverizers are not effective in collecting dust, which endangers the life, health and safety of workers
