Embodiment Construction
[0035] The application will be described in further detail below in conjunction with the accompanying drawings.
[0036] Such as Figure 1-3 As shown, the embodiment of the present application provides an automatic feeding and discharging system for fly ash high-temperature melting treatment.
[0037] Such as figure 1 The application shown here provides an automatic feeding and discharging system for fly ash high-temperature melting treatment, including:
[0038] Fly ash molding unit 1 is used to press the fly ash after the completion of compatibility into regular or irregular three-dimensional blocks, such as: cuboid, cube, other irregular tetrahedron, cylinder, ellipsoid, sphere, hemisphere Wait. During the pressing process, the pressure is controlled at 500~1500T, and the pressing time is 3~200s, so that the moisture content of the fly ash after pressing is controlled at 10Wt.%-30Wt.%, and the density is 1.6~1.8g / cm 3 , and the quality of each molded fly ash is controll...

The invention relates to the technical field of solid waste resource utilization, and discloses an automatic feeding and discharging system for high-temperature melting treatment of fly ash. The automatic feeding and discharging system for high-temperature melting treatment of the fly ash comprises a fly ash forming unit, a three-dimensional warehouse unit, a high-temperature melting furnace and a carbon concentrate feeding unit, wherein a first conveying unit is arranged between the fly ash forming unit and the three-dimensional warehouse unit; a second conveying unit is arranged between the three-dimensional warehouse unit and the high-temperature melting furnace; a third conveying unit is arranged between the carbon concentrate feeding unit and the high-temperature melting furnace; a fourth conveying unit is arranged between the high-temperature melting furnace and the fly ash forming unit; the three-dimensional warehouse unit comprises an automatic warehouse entering and exiting unit and a three-dimensional warehouse; the automatic warehouse entering and exiting unit outputs warehouse goods to the three-dimensional warehouse unit according to the warehouse goods storage duration in sequence; and the warehouse goods with the long warehouse goods storage duration are output preferentially. Automatic forming and melting feeding of the fly ash subjected to high-temperature melting treatment and automatic feeding of carbon concentrates are achieved, continuous circulating operation of the system is achieved, and the working efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of resource utilization of solid waste, in particular to an automatic feeding and discharging system for fly ash high-temperature melting treatment. Background technique [0002] Fly ash refers to the tiny ash particles discharged during the combustion process of fuel (such as coal, domestic garbage, hazardous waste, etc.), and its particle size is generally 1-100 μm, also known as fly ash or soot. Accounting for about 20% of the total amount of waste incineration ash, it is the material collected by the flue gas dust collector after waste incineration. [0003] Fly ash cannot be directly landfilled because it contains a large amount of soluble heavy metals and dioxins, and it is a hazardous waste. Dioxins, heavy metals and a large amount of soluble salts in fly ash can easily seep into soil and groundwater, and then enter the food chain, posing a huge threat to the environment and human health. ...
