Environmentally friendly and pollution-free coal crusher

Abstract

The invention relates to an environment-friendly pollution-free coal briquette crushing machine which comprises a crushing machine main body, wherein a buffer device is arranged at the lower end of a first-level crushing device; the buffer device comprises a loading plate; a fixing rod is arranged at the lower end of an inner chamber of the loading plate; a second buffer plate is arranged on an extending outer wall; a sliding rod is in sliding connection with a sliding groove; and the sliding rod is connected with an electric stretching rod through a connector. According to the environment-friendly pollution-free coal briquette crushing machine, the falling speed of the materials can be reduced through a first buffer plate; the damage to the first-level crushing device caused by the fast falling of the coal briquette can be effectively avoided; and the sliding rod can slide in the sliding groove under the pulling of the electric stretching rod, so as to control the stretching of the stretching part, control the height of the second buffer plate, more effectively reduce the falling speed of the coal briquette, ensure the protection for the crushing device, prolong the service life of the crushing device, ensure more uniform coal grains after being crushed to obtain higher quality, and avoid the environmental pollution caused by harmful gases generated from insufficient combustion in a combustion process.

Description

technical field [0001] The invention relates to the technical field of crushers, in particular to an environmentally friendly and pollution-free coal block crusher. Background technique [0002] At present, the main fuel for thermal power generation is coal. However, in order to ensure the full combustion of coal, the coal is generally broken into coal powder, and then a flame retardant is added to ensure the full combustion of the coal and reduce the emission of harmful gases. However, the crushing process The falling speed of the medium coal block is fast, the crushing effect is poor, the crushed particles are uneven, and it cannot meet the full combustion requirements. For example, the patent application number 201520003443.6 includes the left platform and the right platform. The upper opening of the feeding hopper is the feeding port, and the lower opening of the feeding port is the discharging port. Although the adjustment device can prevent the vibration frequency of t...

[0002] At present, the main fuel for thermal power generation is coal. However, in order to ensure the full combustion of coal, the coal is generally broken into coal powder, and then a flame retardant is added to ensure the full combustion of the coal and reduce the emission of harmful gases. However, the crushing process The falling speed of the medium coal block is fast, the crushing effect is poor, the crushed particles are uneven, and it cannot meet the full combustion requirements. For example, the patent application number 201520003443.6 includes the left platform and the right platform. The upper opening of the feeding hopper is the feeding port, and the lower opening of the feeding port is the discharging port. Although the adjustment device can prevent the vibration frequency of the crushing cylinder from being too high, the coal block falls faster during the crushing process, and the crushing effect is not good. Well, it does not meet the requirements of full combustion, and it will pollute the environment after burning, and because the coal block falls faster, it will cause damage to the crushing device, which will affect the service life of the crusher
