Problems solved by technology

[0005] In order to overcome the fact that briquette is made of coal powder mixed with water to make coal slime, and then demolded, its thickness is relatively large, and there are many through holes. After the coal slime is mixed with water, it is dried to make its texture relatively hard. After burning, the hardness of the burnt honeycomb is still not low, and it is not easy to break. People often pile it up for disposal, and the fly ash in it cannot be extracted, which leads to the soft texture of the outer part of the burnt honeycomb during the extraction process. , easy to shatter and fragment, the inner part of the center is relatively hard, and it is not easy to crush it under the same force. At the same time, there are more fly ash in the burnt briquette, but at the same time, there is also some Some combustion impurities lead to low purity of fly ash, and it is difficult to extract fly ash using honeycomb coal. The technical problem is to provide a fly ash extraction device

Abstract

The invention relates to a fly ash, in particular to a fly ash extraction device. The technical problem is: to provide a fly ash extraction device. The technical solution is: a fly ash extraction device, including a breaking and separating processing mechanism and a peripheral block crushing mechanism; The top of the foot is welded with the first machine tool plate. The invention realizes the breaking up and crushing treatment of the burnt honeycomb briquettes one by one, separates the peripheral part and the inner layer part of the burnt honeycomb briquette and performs crushing and crushing treatment respectively to obtain powder with the same particle size, which is rotated through a screen The fly ash is separated from the mixture by means of the method, so that the smaller and lighter fly ash floats out and separates from the mixture, and floats into the air to collect gas and fly ash at the same time to obtain pure fly ash Effect.

Description

technical field [0001] The invention relates to a fly ash, in particular to a fly ash extraction device. Background technique [0002] Fly ash is tiny ash particles emitted during the combustion of fuels, mainly coal. Its particle size is generally between 1 and 100 μm. Also known as fly ash or soot. Fine solid particles in the flue gas ash produced by fuel combustion. Such as fine ash collected from flue gases in coal-fired power plants. Fly ash is formed when coal powder enters the furnace at 1300-1500°C, undergoes heat absorption by the hot surface under suspension combustion conditions, and then cools down. Due to the effect of surface tension, most of the fly ash is spherical, with smooth surface and small micropores. Part of them are cohered due to collision with each other in the molten state, and become honeycomb composite particles with rough surface and many corners. The chemical composition of fly ash is related to coal composition, coal particle size, boile...
