Description

Technical Field

[0001] The utility model relates to the technical field of fly ash sorting, in particular to a fly ash sorting host machine. Background Art

[0002] Fly ash is a coal combustion product, composed of fine particles of the driven burning fuel, which are discharged from the coal-fired boiler together with the flue gas. The ash that falls to the bottom of the boiler combustion chamber is called bottom ash. In modern coal-fired power plants, fly ash is usually captured by an electrostatic precipitator before the flue gas reaches the chimney or other particle filtering equipment. Together with the bottom ash discharged from the bottom of the boiler, it is called coal ash. In the fly ash processing process, it needs to be sorted and processed by a sorting host to sort out fly ash of different coarseness and fineness. Among them, the "an improved fly ash sorting host" disclosed in the application number "CN214289270U" has solved the problem that the existing fly ash sorting host is easy to be blown away during the sorting. The fly ash separation machine has the following technical disadvantages: it does not have the function of adjusting the coarseness and fineness of fly ash separation, and cannot adjust the screening aperture according to the different coarseness and fineness of fly ash, so that the coarseness and fineness of fly ash screening cannot be adjusted, making it impossible for the device to sort and collect fly ash of different coarseness and fineness; it does not have the function of dust removal and environmental protection, resulting in the inability to remove the raised dust when collecting the sorted fly ash, causing the dust to spread in the working environment, reducing the environmental protection performance of the device, so it is necessary to design a fly ash separation machine.
