A spring 37 is fixedly arranged between the square plate 34 and the bottom of the square blind hole 36, and the spring 37 always tends to make the positioning sleeve 35 contact with the rotating shaft 17. As shown in fig. 7, the positioning pin 38 is installed on the side surface of the positioning sleeve 35 close to the rotating shaft 17, positioning holes 39 matched with the positioning pin 38 are circumferentially distributed on the end surface of the rotating shaft 17, and when the positioning pin 38 is matched with the positioning holes 39 at different positions, the inclination angle of the driven impeller 18 can be changed, so that the wind resistance of the driven impeller 18 to the whole device is changed, the air output of the motor 6 is adjusted, and the effects of energy conservation and emission reduction are achieved.
As shown in fig. 5 and 8, at this time, the fan blade 41 is located at a position perpendicular to the cross section of the second housing 13, the air flow passing capacity is the largest, the corresponding wind resistance is the smallest, and the device is suitable for dust removal operation which can be completed by devices such as the front-mounted impeller 3 and the like with less dust in the air, the wind resistance of the driven impeller 18 in the ultrafine atomized dust filtering device is reduced to the lowest, and the power consumption of the motor 6 in the whole device can be reduced.
Due to the arrangement of the positioning pin 38 and the positioning hole 39, under the elastic force of the spring 37, the rotating shaft 17 and the positioning sleeve 35 keep rotating synchronously, the square blind hole 36 formed in the positioning sleeve 35 is matched with the square plate 34 on the second rotating shaft 33, i.e. the second rotating shaft 33 does not rotate relative to the positioning sleeve 35 and the rotating shaft 17, and because the mounting box 29 is fixedly connected with the rotating shaft 17, the second bevel gear 32 is stationary relative to the mounting box 29, even if the airflow in the second housing 13 has a tendency of blowing the fan blade 41 to rotate relative to the mounting box 29, the first bevel gear 31 and the second bevel gear 32 which are meshed with each other still enable the first rotating shaft 30 not to rotate, i.e. after the positions of the positioning pin 38 and the positioning hole 39 are determined, the driven impeller 18 does not deflect angularly any more.
When the dust content in the air is increased or the dust removal precision needs to be improved, when the driven impeller 18 in the superfine atomized dust filtering device needs to further play a dust removal role, the rotation angle of the driven impeller 18 needs to be adjusted, so that the dust-containing liquid drops passing through the second shell 13 are attached to the driven impeller 18, the driven impeller 18 rotates along with the axial airflow and throws the attached liquid drops onto the inner wall of the shell under the action of centrifugal force to further complete the gas-water separation of the second stage, and the operation steps of adjusting the rotation angle of the driven impeller 18 are as follows: firstly, the rotating handle 40 is pulled to drive the positioning sleeve 35 to compress the spring 37, so that the positioning sleeve 35 is separated from the end surface of the rotating shaft 17, the positioning pin 38 is separated from the positioning hole 39, then the positioning sleeve 35 is rotated to make the positioning pin 38 match with the positioning hole 39 at different positions, in the rotating process, the positioning sleeve 35 drives the second rotating shaft 33 to rotate, so that the second bevel gear 32 and the first bevel gear 31 which are meshed with each other rotate together, the angles of all the driven impellers 18 change accordingly, as shown in fig. 9, which is a schematic diagram of the state when the driven impellers 18 adsorb dust-containing liquid drops to the maximum extent, a positioning hole 39 for positioning the driven impeller 18 in different states between the figures 8 and 9 is also formed on the end surface of the rotating shaft 17, the angle of the driven impeller 18 can be adjusted according to the actual dust removal requirement, so that the power consumption of the motor 6 can be reduced to the greatest extent on the premise of effective dust removal.
Technical scheme of the utility model not be restricted to the utility model the within range of embodiment. The technical contents not described in detail in the present invention are all known techniques.
