Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to an automatic crushing feeder for solid fuels. Background Art

[0002] A solid fuel feeder is a device that is mainly used to transport solid fuel to where it is needed. Its form and working principle may vary depending on the specific application scenario and needs. During the boiler heating process, coal, coal gangue, etc. need to be fed in as fuel through a feeder for combustion and heating. However, existing feeders do not have the function of crushing the fuel when feeding it, which is not conducive to the full combustion of the solid fuel.

[0003] In order to address the above problems, a Chinese patent with an existing announcement number of CN213630500U proposes a high-efficiency feeding mechanism for a boiler. The device feeds solid fuel along a feed hopper so that the solid fuel slides along the feed slope to between the crushing roller and the thickening ring, and then drives the rotating shaft to rotate through a motor, so that the rotating shaft drives the crushing roller to rotate. The crushing roller cooperates with the inner wall of the thickening ring to crush the fuel, thereby ensuring the crushing effect and facilitating subsequent full combustion.

[0004] However, although the above-mentioned efficient feeding mechanism of the boiler can drive the rotating shaft to rotate through the motor, so that the crushing roller and the inner wall of the thickened ring cooperate to crush the fuel, thereby ensuring the crushing effect and facilitating the subsequent sufficient combustion, but when the efficient feeding mechanism of the boiler feeds the solid fuel between the crushing roller and the thickened ring for crushing, the impurities in the solid fuel will also be crushed together, thereby affecting the subsequent combustion of the solid fuel after crushing. Therefore, the utility model provides an automatic crushing and feeding machine for solid fuel to meet the needs. Utility Model Content

The overall structure is simple, which is convenient for screening impurities in the solid fuel and improves the later combustion use of the solid fuel. It solves the problem that when the existing feeder crushes the solid fuel, the impurities in the solid fuel will also be crushed together, thereby affecting the later combustion of the crushed solid fuel.
