Automatic dust falling device for stockpiling

Abstract

The invention relates to the field of material flying dust treatment, in particular to an automatic dust falling device for stockpiling. The device comprises a dust cover, a raised dust collecting device, a spraying device and a lifting mechanism. The dust cover is connected to a discharging opening of a stacker, and the raised dust collecting device is hoisted through the lifting mechanism. Materials fall into the raised dust collecting device to be buffered and then fall to the ground to form a material pile, generated raised dust rises from a gap between a horn mouth and a shell, a dust concentration sensor system detects the dust concentration at a raised dust outlet, a control system controls the rotating speed of a variable-frequency booster pump and the number of atomizing nozzles opened according to data fed back by the dust concentration sensor system, the atomizing nozzles spray upwards to form a water mist layer, raised dust is controlled in the water mist layer and adsorbed, and dust falling is carried out from the source; and meanwhile, the lifting mechanism pulls the shell and a speed adjusting device to move upwards, so that the flow area of the material outlet is gradually enlarged to adapt to the increasing speed of the material pile, the materials are discharged from the position close to the top of the material pile, and dust raising is controlled from the source.

Description

technical field [0001] The invention relates to the field of material dust control, in particular to an automatic dust suppression device for stacking materials. Background technique [0002] In the process of stacking, the circular stacker generally throws the materials directly from a high place. When the crushed materials fall from a high place, a large amount of dust will be formed, which will cause serious pollution to the environment. Therefore, it is necessary to deal with the dust. [0003] In the prior art, most of the methods to deal with the dust generated by the stacker are direct spraying by using the fog cannon to combine the droplets with the dust and then settle down. However, the spraying range of this method is too large, which wastes water resources and directly sprays the materials. It is not suitable for some materials with high dryness requirements. There are also some existing technologies that use follower nozzles to remove dust from material piles, ...
