The two drain pipes 13 are respectively connected to the chambers on both sides of the partition 16. The connecting flat pipe 14 is fixedly connected to the partition 16. The evacuation plate 12 is fixedly connected to the processing box 10. The exhaust port of the first fan 11 is opposite to the evacuation plate 12. The partition 16 forms a plate with the same height as the chamber of the processing box 10. The top of the partition 16 is provided with a notch adapted to the connecting flat pipe 14. The connecting flat pipe 14 is fixedly installed It is installed in the notch and flush with the top of the partition 16. The chambers on both sides of the partition 16 are connected through the connecting flat tube 14. The adsorption component also includes a second fan 15. The second fan 15 is fixedly installed on the side wall of the processing box 10. The second fan 15 and the connecting flat tube 14 are located on the same side of the partition 16. In this solution, the dust-containing gas is sucked into the processing box 10 by the first fan 11, and the beam airflow ejected from the exhaust port of the first fan 11 hits the evacuation plate 12. The top of the evacuation plate 12 is just submerged in water. The beam airflow hits the top of the evacuation plate 12. A ball valve is provided at the port of the drain pipe 13. Water can be injected into the chamber of the processing box 10 or sewage can be discharged through the drain pipe 13. It has a good dust adsorption effect and is easy to maintain.

[0030] The second fan 15 is used to evacuate the chamber on the other side of the partition 16, and then the gas flushed by water is discharged from the connecting flat tube 14 to the other side of the partition 16 and finally discharged by the second fan 15. The blowing of the first fan 11 is coordinated with the exhaust of the second fan 15, so that the air flow rate is fast and the processing efficiency is high.

[0031] like Figure 3 As shown, the adsorption component also includes a dispersion groove 20. The dispersion groove 20 is opened on the top of the evacuation plate 12. The dispersion groove 20 can evacuate the gas discharged by the first fan 11. The evacuation plate 12 is opposite to the exhaust port of the first fan 11. The dispersion groove 20 includes a main groove diagonally distributed along the evacuation plate 12; a plurality of side grooves connected to the main groove, and the side grooves and the main groove together form a leaf-vein-shaped evacuation channel. The leaf-vein-shaped dispersion groove 20 disperses the gas so that the gas is ejected in multiple directions, thereby increasing the contact area between the gas and water and improving the adsorption effect of water on dust.

[0032] like Figure 4 and Figure 5As shown, the adsorption component also includes an air guide groove 30, a wing plate 31 and a steam pipe 32. The air guide groove 30 is fixedly connected to the partition 16. The top of the air guide groove 30 is fixedly connected to a plurality of wing plates 31. The plurality of wing plates 31 form a slit channel. The slit channel is for the port connected to the flat tube 14. The steam pipe 32 is fixedly connected to the air guide groove 30 and extends into the slit channel. The air guide groove 30 forms a frame with a concave cross-section. A plurality of wing plates 31 are symmetrically distributed on the inner walls on both sides of the opposite sides of the air guide groove 30. The size of the wing plate 31 increases uniformly in the direction away from the connected flat tube 14. The plurality of wing plates 31 together form a slit channel with a gradually narrowing opening. The steam pipe 32 is connected to a steam source as a supplement to the above scheme. It is explained that when the connecting flat tube 14 discharges the gas to the chamber where the second fan 15 is located, the gas is blown into the slit channel formed by each wing plate 31. Due to the gradually narrowing design of the opening, the gas flow rate at the tail of the slit channel near the air guide groove 30 is large, and the steam pipe 32 is arranged at the tail of the slit channel, so that the water vapor in the steam pipe 32 can be sucked into the slit channel and mixed with the airflow discharged from the connecting flat tube 14, thereby realizing secondary dust removal of the gas. The water droplets formed by the condensation of water vapor gather in the chamber on the other side of the partition 16 and can be discharged through the sewage pipe 13. The steam source can be a steam generator or an atomizer. The first fan 11 and the second fan 15 are both duct fans, which will not be described in detail here.

Sand making is achieved by rotating the plate hammer to squeeze the ore, and the air is sucked into the air inlet of the first fan 11 through the bellows. With the help of the adsorption component in the processing box 10, multi-stage purification of the air is achieved, with good adsorption effect and high efficiency, which can reduce dust in the sand making environment.

[0034] The working principle of the utility model is as follows: the first fan 11 sucks the dust-containing gas into the processing box 10, and the beam airflow ejected from the exhaust port of the first fan 11 hits the evacuation plate 12, and the top of the evacuation plate 12 is just immersed in water. The beam airflow hits the top of the evacuation plate 12, and a ball valve is provided at the port of the sewage pipe 13. Water can be injected into the chamber of the processing box 10 or sewage can be discharged through the sewage pipe 13. The second fan 15 exhausts the gas in the chamber on the other side of the partition 16, and the gas flushed by water is discharged from the connecting flat pipe 14 to the other side of the partition 16 and finally discharged by the second fan 15. When the connecting flat pipe 1 When the gas is discharged to the chamber where the second fan 15 is located, the gas is blown into the slit channels formed by each wing plate 31. Due to the gradually narrowing design of the opening, the gas flow rate is high near the tail of the slit channel of the air guide groove 30. The steam pipe 32 is arranged at the tail of the slit channel, so that the water vapor in the steam pipe 32 can be sucked into the slit channel and mixed with the air flow discharged from the connecting flat tube 14, thereby achieving secondary dust removal of the gas. The water droplets formed by the condensation of the water vapor gather in the chamber on the other side of the partition 16 and can be discharged through the sewage pipe 13. The steam source can be a steam generator or an atomizer, which will not be described in detail here.
