AI Technical Summary

Technical Problem

When used, the existing coal grinding device is not sufficiently ground, resulting in large coal blocks, affecting the combustion effect of coal and causing energy waste.

Method used

A coal grinding device is designed, including a hammer mechanism, a crushing mechanism and a grinding mechanism. The hammer mechanism initially crushes large pieces of coal through the cooperation of the hydraulic cylinder and the hammer plate; the crushing mechanism further crushes coal with a V-shaped guide plate, a dual-axis motor, a worm and a crushing knife; the grinding mechanism performs deep crushing treatment through a grinding roller and a gear system.

Benefits of technology

This device can effectively improve the grinding efficiency of coal, ensure that the coal block is delicate and uniform, facilitate full combustion, improve combustion efficiency and reduce energy waste.

Abstract

The utility model relates to the technical field of coal processing, and discloses a coal grinding device which comprises a processing box, a feeding port is fixedly formed in the middle of the top end of the processing box, and a hammering mechanism is arranged on the upper portion of the interior of the processing box. Through cooperative use of a hydraulic cylinder, a hammer pressing plate, a sliding block and a sliding groove, conveyed large-block coal can be crushed, preliminarily crushed coal falls off through the two sides of a V-shaped guide plate, through cooperative use of a supporting plate, a double-shaft motor, a worm, a rotating column, a crushing cutter and a worm wheel, the coal can be further crushed, and the coal crushing efficiency is improved. Crushed coal is guided and discharged through the two inclined plates, through cooperative use of the grinding roller, the first gear, the servo motor and the second gear, the coal can be deeply crushed, the device is high in grinding efficiency and good in effect, the combustion efficiency of the coal is improved, and sufficient combustion of the coal is facilitated.
