Wherein, through vapor can pass through the top fixed mounting of stroke sleeve 7 and have last eduction gear 8, the structure of going up eduction gear 3 and going up eduction gear 8 is identical and the structure that goes up eduction gear 8 top and link to each other is identical with the structure that goes up eduction gear 3 bottom and link to each other for the drive rod 41 can go out twice dust suppression operation once carrying out the reciprocating cycle, has improved dust suppression efficiency greatly.
The using method of the invention is as follows:
in the first operation, the driving rod 41 is driven by the expansion machine 9 to move downwards to the discharge device 3 and make the sliding rod 453 contact with the top of the trigger device 32, when the stroke limit is reached, the sliding rod 453 contacts with the trigger device 32 and the arc fixing piece 452 is matched with the arc fixing hole 43 at one side after the compression device 4 reaches the stroke limit, so that the two-way switch device 45 is fixed by the matching action of the arc fixing piece 452 and the arc fixing hole 43, when the driving rod 41 reaches the stroke limit, the driving rod starts to move away from the lower discharge device 3, the water vapor enters the inside of the stroke sleeve 7 through the water vapor input pipe 6, meanwhile, the outside air enters the inside of the stroke sleeve 7 through the adsorber 5, and gradually approaches the upper discharge device 8 while the driving rod 41 moves away from the lower discharge device 3, the sliding rod 453 contacts with the bottom of the trigger device 32 so that the arc fixing piece 452 is matched with the arc fixing hole 43 at the other side, and the compression device 4 will gradually come closer to the lower ejector 3 again in the subsequent stroke, the air pressure in the cavity of the stroke sleeve 7 between the drive rod 41 and the lower ejector 3 will increase, causing the water vapour inside to condense and form small droplets and combine with dust particles.
In the subsequent stroke, when the driving rod 41 approaches the downward discharging device 3, the blocking ball 36 is matched with the blocking piece ii 39 under the action of air pressure, the air in the stroke sleeve 7 cannot leak out through the air inlet pipe 34 and the water vapor inlet pipe 35, so that the inside of the stroke sleeve 7 can stably form a high pressure zone and the water vapor can generate small droplets under the movement of the driving rod 41, in the process that the driving rod 41 leaves the downward discharging device 3, the water vapor enters the water vapor inlet pipe 35 through the water vapor input pipe 6 and enters the inside of the stroke sleeve 7, meanwhile, the air flow generated by the water vapor drives the blocking ball 36 in the inside of the water vapor inlet pipe 35 to move, i.e. apply work to the blocking ball 36, so that the blocking ball 36 is moved to the blocking piece ii 39 at the other end and is matched therewith, and the process can limit the amount of the water vapor entering the inside of the stroke sleeve 7, when steam enters the inside of the stroke sleeve 7 through the steam inlet pipe 35, outside air enters the inside of the stroke sleeve 7 through the air inlet pipe 34 according to the same principle, at the moment, one end of the air inlet pipe 34 is subjected to diameter expansion treatment, the diameter expansion part is fixedly sleeved with the vent plate 37, and a plurality of vent holes are distributed in the surface of the vent plate 37, so that the vent plate 37 cannot be blocked by the blocking balls 36 in the air inlet pipe 34.
When the active rod 41 is compressed during approaching the lower discharging device 3 during discharging, when the bottom of the two-way switching device 45 contacts the trigger device 32, the trigger device 32 moves downward under pressure, and when the axis of the discharge hole ii 326 and the axis of the discharge hole i 33 are located on the same center line after the trigger ring 321 reaches the limit of travel in the annular groove at the top of the discharging body 31, so that the discharge hole i 33 and the discharge hole ii 326 form a complete passage, and thus the internal high-pressure gas can enter the arc-shaped discharge pipe 311 and be discharged from the centralized discharge pipe 312 through the passage formed by the discharge hole i 33 and the discharge hole ii 326, the two-way switching device 45 is disengaged from one side of the inside of the pressing disk 42 during contacting with the trigger device 32 and is engaged with the other side of the inside of the pressing disk 42 under pressing, at this time, high-pressure gas can enter the inside of the pressing disk 42 through the arc-shaped fixing hole 43 and enter the cavity inside the active rod 41 to be discharged through the auxiliary discharge pipe 46.
