Specifically, the overflow pipe 120 extends into the separator body 110 from the top of the separator body 110, one end of the separator body 110, which is far away from the overflow pipe 120, is provided with a dust outlet 181, the side wall of the separator body 110 is provided with an air inlet pipe 170 communicated with the inside of the separator body 110, the air inlet direction of the air inlet pipe 170 is tangent to the separator body 110, the plurality of first rotatable pillars 130 are arranged in the separator body 110 and are close to the inner wall of the separator body 110, the plurality of first rotatable pillars 130 are distributed along the circumferential direction of the inner wall of the separator body 110, the air inlet pipe 170 is communicated with the separator body 110 through the air inlet 171, and the first rotatable pillars 130 are not arranged at the position, corresponding to the air inlet 171, of the inner wall of the separator body.

When the cyclone separator is used, the upper end of the overflow pipe 120 is connected with a fan, dust-containing gas enters the cyclone separator 100 from the gas inlet pipe 170, the gas flows in the separator main body 110 in a rotating manner, the first rotatable small columns 130 are arranged on the side wall of the separator main body 110, the gas can collide with the first rotatable small columns 130 after entering, the first rotatable small columns 130 rotate due to impact force and friction generated by collision, sliding boundary conditions are formed on the rotating gas in the cyclone separator 100, resistance of middle rotating gas is reduced, meanwhile, dust in the dust-containing gas collides with the first rotatable small columns 130 under the action of centrifugal force, and the dust is settled downwards along the side wall of the first rotatable small columns 130 or thrown downwards to the side wall of the separator main body 110 in the rotating process along the first rotatable small columns 130 and finally discharged from the dust outlet 181. Therefore, the first rotatable small column 130 can enable dust in the dust-containing gas to be rapidly settled, the dust removal efficiency is improved, the impact friction area of the gas is increased, the dust removal rate can be improved, and the cleanliness of the gas after dust removal is higher.

Specifically, the lower portion of the separator body 110 is formed in an inverted cone shape, and the dust outlet 181 is disposed at the bottom of the cone.

Further, in order to make the removal efficiency and removal rate higher, the first rotatable pillars 130 are uniformly distributed along the circumferential direction of the inner wall of the separator body 110.

Further, as shown in fig. 3 and 4, the separator body 110 includes a first annular mounting frame 140, the first annular mounting frame 140 is connected to the inner wall of the separator body 110, the first annular mounting frame 140 is provided with first mounting holes 142 matching with the number and size of the first rotatable pillars 130, and one first rotatable pillar 130 is mounted in the first mounting hole 142 through one first bearing 141, that is, the first rotatable pillars 130 are mounted in the first mounting holes 142 in a one-to-one correspondence.

Further, the projection of the first rotatable pillar 130 on the sidewall of the separator body 110 can cover both ends of the air inlet 171. The above arrangement allows dust removal efficiency and dust removal rate to be higher when the dust-laden gas enters from the gas inlet 171 and flows along the side wall of the first rotatable pillar 130 on the side close to the center of the separator while the gas rotates to collide and rub with the first rotatable pillar 130.

Specifically, in the present embodiment, the first annular mount 140 is provided on the upper portion of the separator body 110, and the upper portion of the first rotatable pillar 130 is provided on the first annular mount 140.

The second rotatable pillar 150 provided at the lower end of the overflow pipe 120 also rotates by the rotational friction of the airflow, and the power for the rotation is derived from the central forced vortex of the cyclone 100, so that the rotational speed of the central forced vortex is reduced, thereby reducing the total pressure drop in the overflow pipe 120 due to the dynamic pressure loss. While the rotation of the second rotatable post 150 provided at the lower portion of the overflow pipe 120 blocks a part of the short-circuit flow. The second rotatable pillar 150 reduces the resistance of the side wall and the pressure loss of the central forced vortex, increases the contact chance of the side wall to dust, and can further remarkably improve the dust removal efficiency and the dust removal rate.

In order to further improve the dust removing efficiency and the dust removing rate, the second rotatable pillars 150 are uniformly distributed along the lower circumference of the overflow pipe 120.

Further, as shown in fig. 4 and 5, the lower portion of the overflow pipe 120 is provided with a second annular mounting frame 160, the second annular mounting frame 160 is provided with second mounting holes 162 matching the number and size of the second rotatable posts 150, and one second rotatable post 150 is mounted in the second mounting hole 162 through one second bearing 161.

This arrangement allows the second rotatable post 150 not only to rotate but also to revolve around the overflow pipe 120 under rotational friction of the air flow, and further allows the rotational speed of the central forced vortex to be reduced, thereby reducing the total pressure drop in the overflow pipe 120 due to dynamic pressure loss, and further improving the dust removal rate and dust removal efficiency.

The air inlet pipe 170 is connected to the separator body 110 through the air inlet 171, and an end of the overflow pipe 120 near the dust outlet 181 is an air outlet end 121, and further, the air outlet end 121 is closer to the dust outlet 181 than the air inlet 171.

The gas outlet end 121 is closer to the dust outlet 181 than the gas inlet 171, that is, the gas inlet 171 is higher than the gas outlet end 121 when the cyclone 100 is in use.

Further, a dust discharge pipe 180 is provided at an end of the separator body 110 away from the overflow pipe 120, and the dust discharge pipe 180 communicates with the dust outlet 181.

To sum up, the utility model provides a cyclone, because the position that is close to the lateral wall in the separator main part is provided with a plurality of first rotatable columellas, make behind the dirty gas access device with many first rotatable columellas production collisions, because impact and the friction that the collision produced make first rotatable columella rotate, will form the boundary condition that slides to the rotatory gas in the cyclone, the gaseous resistance of middle rotatory has been reduced, consequently, the dust in the dirty gas can be subsided fast to the concrete setting of first rotatable columella, the efficiency of dust removal is improved, and because gaseous striking friction area increases, the dust removal rate can also be improved, make the gas cleanliness after the dust removal higher. And because the lower part of the overflow pipe is provided with the plurality of second rotatable small columns, the second rotatable small columns also rotate under the rotational friction of airflow, the power for the rotation of the second rotatable small columns comes from the forced vortex at the center of the cyclone separator, so that the rotational speed of the central forced vortex is reduced, and the total pressure drop caused by dynamic pressure loss in the overflow pipe is reduced. And the rotation of the second rotatable column arranged at the lower part of the overflow pipe blocks part of the short-circuit current. Therefore, the resistance of the side wall and the pressure loss of the central forced vortex are reduced by the arrangement of the second rotatable small column, the contact chance of the side wall to dust is increased, and the dust removal efficiency and the dust removal rate can be further remarkably improved.
