Description

TECHNICAL FIELD

[0002] The ash in coal is one of the coal pricing indicators, and the ash can be removed by washing coal to improve the combustion efficiency. The external ash is from the rock fragments in the top and bottom plate and the dirt band, which is greatly related to the rationality of the coal mining method. Most of the external ash can be removed by sorting. The internal ash is the inorganic matter contained in the original plant itself that forms coal. The higher the internal ash, the worse the coal selectivity. The ash is a harmful substance. Ash determination can understand the content of inorganic matter in the substance, help judge the purity and quality of the substance, remove organic matter by high-temperature calcination, and the residual inorganic matter is the ash. The content and composition of the ash can reflect the chemical properties and mineral composition of the substance.

[0003] The existing coal ash detection usually uses a Muffle furnace to heat the coal sample. The sample placed in the Muffle furnace needs to be dried and crushed in advance. The sample needs to be collected manually before detection. Since the collected coal sample is too large to be directly detected, the coal sample needs to be ground after preliminary crushing to achieve the required sample particle size. The operation steps are cumbersome. Therefore, we propose a coal ash detection device. UTILITY MODEL CONTENT
