A stacking automatic dust suppression device

Abstract

The invention relates to the field of material dust control, in particular to an automatic dust suppression device for stacking materials. It includes a dust cover, a dust collection device, a spraying device and a lifting mechanism. The dust cover is connected to the discharge port of the stacker, and the dust collection device is hoisted by the lifting mechanism. The material falls into the dust collection device for buffering and falls to the ground to form a material pile. The generated dust rises from the gap between the bell mouth and the shell. The dust concentration sensor system detects the dust concentration at the dust outlet. The control system uses the data fed back by the dust concentration sensor system Control the speed of the frequency conversion booster pump and the opening number of atomizing nozzles. The atomizing nozzles spray upward to form a water mist layer, control the dust inside the water mist layer for adsorption, and carry out dust reduction at the source; at the same time, the lifting mechanism pulls the casing and the speed control device upward. The movement makes the circulation area of ​​the material outlet gradually expand, so as to adapt to the growth rate of the material pile, so that the material is discharged near the top of the material pile, and the generation of dust is controlled from the source.

Description

technical field [0001] The invention relates to the field of material fugitive 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 directly throws the material from a high place. When the crushed material falls 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 fugitive dust of the stacker are to use a fog cannon to spray directly, so that the droplets are combined with the dust and then settle. It is not suitable for some materials with high dryness requirements. There are also some existing technologies that use follow-up nozzles to remove dust from the material pile, but only for dust reduction and lack of means to suppress the generation of dust, and the dust removal eff...

Problems solved by technology

[0004] According to at least one shortcoming of the prior art, the present invention proposes an automatic dust reduction device for stockpiling to solve the problem that the existing dust reduction device easily causes excessive moisture in the material and poor dust reduction effect
