Background

Lignite, also known as lignite (coal; brown coal; wood coal), is a mineral coal with the lowest degree of coalification. A low-grade coal with dark brown color and no luster is between peat and bituminous coal. The chemical reactivity is strong, the air is easy to be weathered in the air, the storage and the transportation are not easy, and the air is seriously polluted during the combustion. However, because high-quality coal is almost mined out, lignite becomes the coal mainly used in China, but because the coalification degree of lignite is too low, a large amount of black ash floats in the air during combustion, and if the high-quality coal is not subjected to coal washing treatment and extraction, the haze problem in China is increasingly serious due to the large use of poor-quality lignite.

Lignite enters the heating rotary drum through the double-helix feeding device to be dried in the drying process, hot air is introduced into the existing drying drum to be used for drying lignite entering the drying drum, but airflow flows backwards into the spiral feeding machine in the drying process, so that parts inside the spiral feeding machine are easily corroded and damaged in a high-temperature and high-humidity environment, and the service life of the spiral device is shortened.

Accordingly, the present invention provides a double helix feeding device to solve this problem.
