The working principle is that dusty or liquid-containing airflow enters the cyclone separator through the air inlet, airflow rotating around the axis of the cyclone separator is formed in the cyclone separator, under the action of centrifugal force, dust or liquid drops are thrown to the outer wall and downwards collected to the collecting bin through the dust discharging port, and clean gas is discharged through the air outlet pipe in the center. The centrifugal force for the particles is much greater than the gravitational and inertial forces, so that the minimum particle size for a cyclone separator to be able to separate economically can be up to 5-10 μm.

The working principle of cyclone dust removal is that after gas containing dust particles enters the interior of a cyclone dust collector through an air inlet pipe, the dust-containing gas is rotated by a rotating structure through an air inlet to generate rotating airflow, the rotating airflow rotates along the cone from top to bottom to form external rotating airflow, the dust is thrown on the inner side wall of the cone by the rotating airflow under the action of centrifugal force in the movement process, the downward rotating airflow reaches the bottom of the cone and then rotates upwards to spirally enter an exhaust pipe, internal rotating airflow is formed, the internal rotating airflow is finally discharged by the exhaust pipe, the traditional conical flow guide pipe structure is used for being adopted at present, the requirement for use can be met to a certain degree, effective diversion and guiding effects are lacked for the airflow entering the cyclone dust collector, the internal rotating airflow inevitably carries some loose dust at the bottom of the cone in the process of upward movement from the bottom, and the discharged gas is inevitably purified thoroughly.

Therefore, the utility model provides a take cyclone of guiding device solves this problem.

The utility model discloses a through following technical scheme realization, a take cyclone of guiding device, including the cyclone body, set up intake pipe and blast pipe on the cyclone body, fixed setting is used for purifying exhaust's guiding device on the blast pipe inside wall, the last drag reduction structure that sets up of guiding device.

In order to further optimize the utility model discloses, can prefer following technical scheme for use:

preferably, the distance from the bottom end of the flow guide device to the bottom end of the exhaust pipe is not less than the radius of the exhaust pipe.

Preferably, the flow guide device is a plurality of air guide plates which are perpendicular to the inner side wall of the exhaust pipe, the air guide plates are uniformly arranged along the circumferential direction of the exhaust pipe, and two side surfaces of each air guide plate are provided with adhesive layers.

Preferably, the drag reduction structure is an exhaust gap between the air deflector and the exhaust pipe.

Preferably, the resistance reduction structure is an air vent hole between the air deflector and the air exhaust pipe, and the air vent hole is uniformly arranged along the edge of the air deflector.

Preferably, the inner diameter of the air deflector is a conical structure.

The beneficial effects of the utility model reside in that:

through set up guide structure on the blast pipe inside wall, avoid guide structure to lead to the air current to discharge the air current to form too big resistance simultaneously and discharge not smoothly, set up drag reduction structure on guiding device, make inside rotatory air current when the air current strikes guide structure when the in-service use with the inside a small amount of dust adhesion of smuggleing secretly on guide structure, finally make the exhaust air current further obtain purifying.
