Coal scrap auxiliary drying device

Abstract

The invention discloses a coal scrap auxiliary drying device. The coal scrap auxiliary drying device comprises a mounting box, a mounting cavity is formed in the mounting box, a motor is fixedly mounted on the bottom end wall of the mounting cavity, the upper end of the motor is in power connection with a first shaft, a first bevel gear and a second bevel gear are fixedly mounted on the upper partand the lower part on the first shaft correspondingly, a first fixed block is fixedly mounted on the bottom end wall of the mounting cavity, a second shaft is rotatably mounted in the first fixed block, and a third bevel gear engaged with the second bevel gear is fixedly mounted on the second shaft. Screened small-particle coal is collected and prompted to be heated and combusted to provide powerfor a drying cavity, and thus energy supply of drying is reduced; integrated utilization of resources is promoted, and thus waste of the resources is avoided; and then water vapor generated by evaporation is collected to avoid leakage.

Description

technical field [0001] The invention relates to the technical field related to coal, in particular to an auxiliary drying device for coal waste. Background technique [0002] my country is a country with energy resources mostly coal, and its coal output ranks first in the world, and it is increasing year by year. With the increasing demand for energy and the exploitation of coal resources, the development and utilization of coal mines will become more and more important in my country. However, the high water content in coal mines makes transportation costs high, which is not conducive to long-distance transportation and storage. And in the process of screening and drying, a lot of small particles of coal are often left and discarded, which cannot effectively save mineral resources for coal mine resources, resulting in waste of resources, and requires a large amount of supply during drying. Yes, it can't save resources very well. Contents of the invention [0003] Aiming ...
