Description

Technical Field

[0001] The utility model relates to the technical field of fly ash and slag treatment equipment, and particularly relates to a fly ash and slag salt washing device. Background Art

[0002] The fly ash and slag salt washing device is a device specifically used for treating fly ash and slag. Its core function is to wash fly ash and slag through a specific process to remove salts and other harmful substances therein. This device has a wide range of applications in the fields of environmental protection and resource recycling. For example, a fly ash and slag salt washing device with the application number CN202122084117.0 specifically discloses a drum screen, a mounting rack for placing the drum screen, a driving structure arranged outside the drum screen, a water tank arranged below the drum screen, a feeding hopper arranged at the front end of the drum screen, a rack for erecting the feeding hopper, a discharging hopper arranged at the rear end of the drum screen, and a conveyor belt connected to the discharging hopper. The driving structure includes a motor arranged outside the drum screen, a driving wheel arranged at the front end of the motor, a rotating shaft penetrating through the inside of the drum screen, a driven wheel arranged at one end of the rotating shaft, and a belt connecting the driving wheel and the driven wheel. When the existing fly ash and slag salt washing device feeds materials, the materials fall into a certain fixed position inside the device, and the material distribution is uneven. The uneven material distribution will cause the contact area between the washing medium (such as water) and the materials to decrease, thereby reducing the washing effect. The materials in some areas may be too concentrated and cannot be fully washed; while in other areas, there may be too few materials, resulting in waste of washing resources. Therefore, we propose a fly ash and slag salt washing device. Content of the Utility Model
