The air outlet 6 is connected with an air outlet, which is used to discharge the filtered air flow inside the box body 1, thereby reducing the concentration of mineral dust on the working face.

The water tank 2 is located below the box body 1 and is used for storing water. The top of the water tank 2 is provided with an upper partition 7 for separating the tank 1 from the water tank 2. The upper partition 7 is provided with a plurality of backflow holes 701 through which the water in the tank 1 flows into the water tank. middle.

The spray pipe 3 is provided with a water inlet 301 at one end, and the water inlet 301 is arranged in the water tank 2. The main part of the spray pipe 3 is arranged at the bottom of the box body 1 along the length direction of the box body 1, so that the spray pipe 3 runs through the entire box body 1 in the length direction, the other end 302 of the spray pipe 3 extends to one end of the box body 1 in a blocked state. A plurality of vertical branch pipes 8 are arranged on the side wall of the spray pipe 3 , and an upper spray head 9 is arranged on the top of the branch pipes 8 . The water in the water tank 2 enters the branch pipe 8 through the spray pipe 3, and then sprays in the casing 1 through the upper spray nozzle 9 to purify the air in the casing 1.

Preferably, in addition to setting the upper spray head 9 on the branch pipe 8, the lower spray head 10 can also be directly installed on the spray pipe 3, so that the upper spray head 9 and the lower spray head 10 spray water mist upwards and downwards respectively , by spraying small particles of water droplets, the water droplets and the mineral dust particles in the air are bonded or the mineral dust is attached to the surface of the water droplets, so that the mineral dust and the air are separated, and all the air is within the spraying range as much as possible , to ensure the dust removal effect.

The upper spray head 9 and the lower spray head 10 can utilize 3/4 inch single-hole copper spray heads commonly used in the prior art, and the rated water output is 1.2 L/min.

The filter screen 4 is arranged on the side of the branch pipe 8, and the spraying direction of the upper spray head 9 is towards the filter screen 4. Those skilled in the art can understand that there may be multiple branch pipes 8 , and the number of upper spray heads 9 corresponds to the number of branch pipes 8 . Correspondingly, the quantity of filter screen 4 also can be multiple, corresponding to upper spray head 9, the water mist that makes upper spray head 9 spray washes filter screen 4, and the mineral dust on filter screen 4 is brought into water tank 2 to further purify the air. The height of the branch pipe 8 is not specifically limited here, and the height of the branch pipe 8 can be referred to the height of the box body 1.
