Arch breaking device for raw coal cabin

Abstract

The invention relates to an arch breaking device for a raw coal cabin, which comprises thea raw coal cabin, wherein the lower end of the raw coal cabin is provided with a two-way electric insertion door and an insertion type expansion joint, the lower end of the raw coal cabin is connected with a coal feeding machine, the raw coal cabin is a in double-curve type funnel shape, both sides of athe funnel neck are provided with transverse arch breaking devices, and a vertical arch breaking device is arranged inside the raw coal cabin along the cabin wall. The arch breaking deice has the advantages that the structure is simple, the manufacturing cost is low, the installation and the maintenance are convenient, the work time of an electromagnetic reversing valve can be set through a control box for realizing the dredge at the fixed time, the combination of the vertical arch breaking and the transverse arch breaking is adopted, the optimum dredge effect can be reached, the labor power is greatly saved, and in addition, the work efficiency is improved by several times.

Description

Technical field: [0001] The invention relates to a dredging device in the process of conveying solid materials, in particular to an arch breaking device for a raw coal bunker. Background technique: [0002] In the process of conveying powdery, granular, blocky or mixed solid materials, due to the humidity, high viscosity or large conveying volume of the materials, the materials will adhere to the silo wall or be blocked in the silo or cone. In containers such as buckets, the flow is cut off, which affects the normal and continuous production, especially in the process of transporting raw coal in thermal power plants. Because the raw coal has small particles, high ash content, high water content, and many sundries, the pressure of the upper coal can easily cause the raw coal to be squeezed into blocks to form tent coal, resulting in potential safety hazards. [0003] At present, the more commonly used method is to manually use a sledgehammer to beat the bucket wall vigorousl...

AI Technical Summary

Problems solved by technology

[0002] During the process of conveying powdery, granular, massive or mixed solid materials, due to the humidity, high viscosity of the materials or the large conveying volume, the materials will adhere to the silo wall or be blocked in the silo or cone. buckets and other containers, resulting in cut-off, which affects the normal and continuous production, especially in the process of transporting raw coal in thermal power plants.

Due to the small particles of raw coal, high ash content, large water content, and many sundries, the pressure of the upper coal can easily make the raw coal squeeze into blocks to form tent coal, resulting in safety hazards

[0003] At present, the more commonly used method is to manually use a sledgehammer to beat the bucket wall vigorously, which is effective for short-term awning coal, but not helpful for long-term awning coal, and must be thoroughly cleaned inside the coal hopper

The workload is heavy and seriously affects normal production
