Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic ash conveying, in particular to an anti-clogging silo bottom ash unloading device. Background Art

[0002] A humidifying mixer, also known as a fly ash humidifying mixer, is used for wet mixing and conveying powdered materials in ash hoppers in thermal power plants and other facilities. It is also suitable for humidifying, mixing, and conveying solid particulate materials in chemical and mining industries. The humidifying mixer uses two sets of spiral blades to evenly feed material into the main unit. The dry ash and powdered materials entering the mixing and stirring troughs are forcibly mixed and stirred by water supplied by a water supply system. The material, which meets the humidity requirements, is then conveyed to the discharge port.

It includes a box body, a dust collection bin, a dust removal bin and an air purification bin. A dust collection port connected to the outside of the dust collection bin is provided on one side of the vacuum cleaner, and a dust conveying pipe is connected to the other side of the vacuum cleaner. The upper end of the dust removal bin is connected to a water pipe, and the front end of the water pipe is connected to a spray head. The lower part of the interior of the dust removal bin is connected to a dust filter net, and heaters are provided at the upper and lower ends of the interior of the air purification bin, and an air purifier is provided on the inner wall of the air purification bin.
