The present invention relates to a moisture mixing device for preventing the scattering dust generated when discharging dust collected in the dust collector device for collecting dust and scattering dust generated during transport of the transport in the belt conveyor equipment, in more detail The present invention relates to a water mixing device mounted on the lower part of the dust collecting hopper and discharging dust and water to the lower part through the upper and lower fuselage parts and screws mounted therein.

In general, a dust collector installed in a raw material processing facility is a device for collecting and treating dust generated in the process of transporting iron ore and secondary raw materials, and is installed separately for each process. Due to the characteristics of the raw materials, the raw materials themselves contain a large amount of fine powder, and dust and scattering dust are generated in a large amount during the transportation operations from the unloading operation to the transportation process and the crushing process and the related process.

Particularly, in the raw material processing crushing process, since 20 to 30 belt conveyors are connected to one dust collector, the collection capacity of the dust collecting dust increases, which causes a large amount of dust and scattering dust during discharge. Referring to the structure and operation of the dust collector which is installed to effectively collect the dust generated during such work as follows.

As shown in FIG. 1, a suction dust collecting pipe 102 is installed at a main part of a facility where dust and scattering dust are generated and sucked into the dust collecting hopper 100. The sucked dust is attached to the bag filter 101 installed inside the dust collecting hopper 100 when the air is discharged to the discharge pipe 103 by the discharge force of the air discharge device of the dust collector. At this time, the air passes through the bag filter 101 and is discharged to the discharge pipe.

When the dust attached to the bag filter 103 hits the bag filter 101 by the blowing force of the compressed air, the compressed air injector installed above the bag filter 101 is blown through the air pipe 104 installed outside the dust collector. Dust attached to the bag filter falls to the bottom of the dust collecting hopper 100. Dust, which is accumulated at the bottom of the dust collection hopper, is transported by the screw conveyor 105 which is operated at the bottom of the dust collection hopper, and is transferred back to the integrated screw conveyor 106 of the lower portion and the lower process pipe 108 is passed through the rotary valve. Fall).

In the discharge operation of the dust collector, in the related art, the water adding device installed in the lower portion of the processing pipe 108 to remove dust and scattering dust generated during the discharge operation does not control the amount of moisture, so that a large amount of moisture is added. In this case, a large amount of moisture is contained in the dust to be discharged to make bamboo light, which causes a problem of falling light in the lower belt conveyor. In addition, when less moisture is added compared to the amount of dust, there is a problem in that the dust is not evenly contained in the discharged dust and thus the effect of preventing dust and scattering dust is lost.

Moreover, the dust collecting dust 201 collected in the dust collector as described above is discharged to the lower belt conveyor 200 in a very fine and dry state, thereby recurring a large amount of dust and scattering dust at the upper portion of the belt conveyor 200. There is a problem, the dust is recurred at the connection portion of the belt conveyor during the transport operation, and the dust is collected again in the dust collector, the dust collection and discharge operation is repeated, the dust collection efficiency is reduced, which is the main cause of environmental pollution.

The present invention is to solve the above problems, by detecting the amount of dust discharged when the discharge of the fine and dry dust collected in the dust collection hopper of the dust collector and control the amount of water to be controlled, the predetermined amount to the dust collected It is an object of the present invention to provide a device for preventing the generation of scattering dust during dust discharge and effectively removing dust by adding, mixing and discharging moisture.

As a constituent means for achieving the above object, the present invention is a device for mixing moisture from the dust collector, the spraying nozzle for spraying water inside the induction pipe and water supply pipe connected to the dust collector It is connected, the lower portion is formed in a cylindrical shape that is larger in diameter, the upper body portion formed in the lower surface opening; It is formed in a cylindrical shape that becomes smaller in diameter toward the bottom, the discharge pipe for discharging dust is connected, the upper surface is engaged with the upper fuselage portion is formed as an opening, the outer peripheral portion of the upper surface is elastically supported on the outer support Fuselage; A mixing screw part fixed to the lower body part so as to be rotatable through a bearing and inserted into the upper body part and the lower body part, wherein a spiral screw blade is formed along a central axis; And when dust is transferred from the dust collector and a predetermined amount is laminated on the screw blades of the mixing screw part, the lower fuselage part is moved downward by the load, and the position is detected at this time to reversely rotate the central axis of the mixing screw part and to spray water. And a control unit for mixing the dust with water and controlling the discharge of dust mixed with water by rotating the central axis forward again.
