Technical Field

[0001] The utility model belongs to the technical field of goaf filling, and in particular relates to a demisting device for a sand regulating barrel in a mine filling area. Background Art

[0002] During the filling operation of the mine goaf, the regulating barrel is an important facility for stabilizing the sand release project. Different sand bins are fed into the regulating barrel according to the amount, and the goaf is filled after mixing in the regulating barrel. The liquid level and filling concentration of the regulating barrel are very critical. There are currently two ways to monitor the liquid level of the regulating barrel. The first is to use a radar level meter, and the second is camera monitoring. The data collected by the former fluctuates frequently and is unstable, causing operators to frequently adjust the regulating valve, increasing the workload, and the life is short and the cost is high. Due to the large amount of water vapor that will gather in the regulating barrel to form water mist during the tailings filling process, it affects the visibility of the camera monitoring. For this reason, it is very necessary to develop a demisting device for the sand regulating barrel in the mine filling area to ensure that the camera can monitor the regulating barrel normally.
