Referring to fig. 1 to 3, according to the embodiment of the present invention, a cyclone separator includes a tank 100 and a dust collection funnel 200, the tank 100 includes a dust removal chamber 150 and a dust collection chamber 160, a partition plate 110, an air inlet 120, an air outlet 130 and a dust discharge port 140 are provided on the tank 100, the air inlet 120 and the air outlet 130 communicate with the dust removal chamber 150, the air inlet 120 is provided along a downward direction of a tangent line of an outer wall of the tank 100, the air outlet 130 is provided at an upper end of the tank 100, the dust discharge port 140 communicates with the dust collection chamber 160, the partition plate 110 is used for separating the dust removal chamber 150 and the dust collection chamber 160, the dust collection funnel 200 is provided with a plurality of dust collection funnels 200, the dust collection funnel 200 is installed on the partition plate 110, and the dust collection funnel 200 communicates with the dust removal chamber 150 and the dust collection chamber 160.

The dust-laden air enters the tank 100 from the air inlet 120, the air flow changes from linear motion to circular motion and moves along the inner wall of the tank wall 100 of the tank 100, and most of the rotating air flow spirally flows downwards from the cylinder along the wall and towards the cone. The particles are thrown by centrifugal force towards the wall, and once they contact the wall, they lose their inertial force and fall down the wall by the momentum of the downward axial velocity near the wall, sliding into the collection funnel 200, and falling from the collection funnel 200 into the collection chamber 160. And a plurality of complicated small vortexes can be formed, so that ascending air flow cannot naturally form upward cyclone and only can ascend to the air outlet in a straight line, the condition of secondary dust entrainment is reduced, and the gas-solid separation rate is greatly increased. The gas can form a plurality of complicated small vortexes through the integrated funnel, so that the ascending gas flow can not form an inner rotational flow which rotates upwards like a common cyclone separator, and the gas flow can only rise to the gas outlet in a straight line, thereby reducing the secondary entrainment of dust and greatly improving the gas-solid separation rate.

In some embodiments of the present invention, partition 110 is a tapered structure that protrudes toward dirt collection chamber 160. The path of the dust-carrying air entering the tank 100 is firstly spirally descending along the inner wall of the tank 100, the partition plate 110 is downwards convex, so that the spiral air flow is converged towards the center of the tank 100, the dust collection funnel 200 is arranged on the partition plate 110, and the air is more easily cut into the dust collection funnel 200.

In some embodiments of the present invention, the dust collecting funnel 200 includes a funnel body 210, a connecting rod 220 and a backflow baffle 230, the funnel body 210 is installed on the partition board 110, the backflow baffle 230 is connected to the funnel body 210 through the connecting rod 220, the backflow baffle 230 is used for shielding the lower end opening of the funnel body 210, and a flow guiding gap is formed between the backflow baffle 230 and the funnel body 210. The spiral airflow is converged along the central direction of the partition board 110, cut into the dust collecting funnel 200 along the partition board 110 and spirally descend along the inner wall of the funnel body 210, so that the flowing mode of the airflow is changed, the ascending airflow is greatly weakened, the secondary entrainment of dust is reduced, and the gas-solid separation rate is greatly improved; the dust slides down along the inner wall of the tank 100, and then enters the dust collecting chamber 160 through the guiding gap after entering the dust collecting funnel 200.

In some embodiments of the present invention, the funnel body 210 narrows from top to bottom. The gradual narrowing of the funnel body 210 enables the helical path of the air flow to be continuously constricted, and the ascending air flow to be continuously weakened.

In some embodiments of the present invention, the funnel body 210 is provided with a mounting plate 240, and the mounting plate 240 is connected to the partition 110 by screws. The dust collecting funnel 200 is convenient to disassemble and assemble and is convenient to clean.

In some embodiments of the present invention, there is a smooth transition between the mounting plate 240 and the funnel body 210. The impact of the spiral air flow entering the dust collecting funnel 200 is reduced, so that the air flow enters dust collecting holes along the smooth surface.

In some embodiments of the present invention, the backflow barrier 230 is convex toward the upper side of the funnel body 210. The two ends of the backflow baffle 230 are low and the middle is high, and dust moves towards the two ends due to the action of gravity until entering the dust collection chamber 160 through the diversion gap; meanwhile, the arrangement of the backflow baffle 230 can prevent the dust from being brought back to the dust collecting funnel 200 by the airflow in the dust collecting chamber 160, thereby improving the dust removal rate.

In some embodiments of the present invention, the dust collection funnels 200 are evenly distributed around the axis of the tank 100. The spiral air flow passes through the dust collecting hoppers 200 uniformly distributed, and the wind force is uniformly weakened.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
