Abstract
The utility model discloses a dust catching device for a return air course of a coal mine, which comprises an atomizing device and a double-layer gauze element. The atomizing device is mounted on a top plate on the return air course, the double-layer gauze element is suspended on the top plate of the return air course, meshes of the double-layer gauze element are smaller than 1.5mm, the double-layer gauze element covers the section of the integral tunnel, and the atomizing direction of the atomizing device faces the double-layer gauze element. The dust catching device has the advantages that static dust is adhered onto the wet gauze element and timely flushed by atomized water flow when flowing through the double-layer gauze element, accordingly the dust in the return air course is purified, atomization can be stopped by the aid of infrared control when someone passes, and a pedestrian can pass the gauze element by lifting up the gauze element.
Description
Technical field
The utility model relates to the dust removing down-hole of coal mine device.
Background technology
In the underground mining of colliery, can reduce most of dust by atomization mechanism to measures such as digger spray sprinklers, but still some static dust enters in the return, make the down-hole return have dust, influence workers ' health.
Summary of the invention
The utility model provides a kind of dust arrester that uses in the return aircourse, colliery.
The dust arrester that return aircourse, a kind of colliery is used, it comprises the atomization mechanism that is installed on the top board of return aircourse, it is characterized in that, it also comprises a double-deck gauze that is suspended on the top board of return aircourse, the mesh of double-deck gauze is less than 1.5mm, and covering the whole tunnel section, the spray direction of atomization mechanism is towards double-deck gauze.
Good effect of the present utility model is: when static dust is flowed through double-deck gauze, stick on the moist gauze and in time washed by the spraying current, the dust in the return aircourse is purified.When the people passes through, can end spraying by infrared controlled stop, the pedestrian starts gauze and can pass through.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Marginal data: 1---double-deck gauze; 2---atomization mechanism.
The specific embodiment
With reference to accompanying drawing the utility model is further specified.
As shown in Figure 1, it comprises atomization mechanism 2 that is installed on the top board of return aircourse and the double-deck gauze 1 that is suspended on the top board of return aircourse, and the mesh of double-deck gauze 1 is less than 1.5mm, and covering whole tunnel section, and the spray direction of atomization mechanism 2 is towards double-deck gauze 1.
