Coal particle drying device

Abstract

The invention provides a coal particle drying device. The coal particle drying device comprises a drying cylinder for drying coal, a supporting base for supporting the drying cylinder, an inclined surface material turning mechanism for turning the coal and a uniform material screening mechanism, wherein the bottom of the drying cylinder is fixedly connected with the supporting base, the inclined surface material turning mechanism is arranged on the drying cylinder, and the uniform material screening mechanism is arranged on the drying cylinder and the inclined surface material turning mechanism. The invention relates to the field of coal processing. According to the coal particle drying device, a special structure which can facilitate uniform dispersion, improve the lift and turn the coal at various angles is designed according to the problems that in an existing coal drying process, the coal is prone to bonding, low in lift and not prone to turning, and thus, the problems that a common drying device difficultly uniformly turn the coal, the coal rolling amplitude is small, the coal is prone to accumulation, the lift in the cylinder is low, the coal drying is not uniform, and the drying efficiency of the coal is influenced to a certain extent are effectively solved.

Description

technical field [0001] The invention relates to the technical field of coal processing, in particular to a coal particle drying device. Background technique [0002] When drying coal, it is necessary to use a drying device to dry it. The current drying method is mainly heating and drying. Through the transfer of heat, the hot air will take away the evaporated moisture in the coal. Instead, the common dry carrier used is the drum. During the rotation of the drum, the heat is transferred to the coal through the inner wall of the drum. At the same time, the rolling drum can turn the coal, and then can contact the coal as evenly as possible. However, at present During the rolling process of the coal by the drum, the coal is still piled up at the bottom under the influence of gravity, the height of the coal turning process is limited, and the turning range is small, especially when the humidity is high, the coal is lumped together, and the coal The lifting height affects the dry...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a coal particle drying device, which solves the problem that the general drying device is difficult to evenly turn the coal, the rolling range of the coal is small, it is easy to pile up, the head in the cylinder is low, and the coal drying is difficult. Uneven drying affects the drying efficiency of coal to a certain extent
