Description

Technical Field

[0001] The utility model relates to the technical field of chemical dust removal, in particular to a cyclone dust collector main body structure. Background Art

[0002] Cyclone dust collector is a type of dust removal device. The dust removal mechanism is to make the dust-laden airflow rotate, separate the dust particles from the airflow and capture them on the wall with the help of centrifugal force, and then use gravity to make the dust particles fall into the ash hopper. Each component of the cyclone dust collector has a certain size ratio. Every change in the proportional relationship can affect the efficiency and pressure loss of the cyclone dust collector. Among them, the diameter of the dust collector, the size of the air inlet, and the diameter of the exhaust pipe are the main influencing factors. When using it, it should be noted that when a certain limit is exceeded, favorable factors can also be transformed into unfavorable factors. In addition, some factors are beneficial to improving the dust removal efficiency, but will increase the pressure loss, so the adjustment of each factor must be taken into account.

[0003] Existing cyclone dust collectors usually have a dust collecting area for collecting impurities at their bottom, but the existing dust collecting area is usually box-type. The impurities in the box-type dust collecting area are not easy to be discharged, and the impurities are also easily attached to the inner wall of the dust collecting box, which is not convenient for cleaning, resulting in increased cleaning costs and difficulty in meeting the use needs of modern cyclone dust collectors.

DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0022] When the dust impurities in the dust collecting tank 2 need to be discharged, the stirring component 3 in the dust collecting tank 2 is started to prevent the dust impurities from agglomerating or adhering to the dust collecting tank 2, and the discharging component 4 is started to discharge the dust impurities in the dust collecting tank 2.

[0023] Furthermore, the dust removal tank 1 includes a first cylinder 11, a first conical cylinder 12, an exhaust pipe 13, an air inlet pipe 17 and a guide plate 14. The first cylinder 11 is vertically arranged at the top of the first conical cylinder 12, the exhaust pipe 13 is arranged on the outer wall of the top of the first cylinder 11 and extends into the first cylinder 11, the air inlet pipe 17 is arranged on the outer circumferential surface of the top of the first cylinder 11, and the guide plate 14 is spirally arranged at the top of the first cylinder 11 and connected to the air inlet pipe 17.

The gas containing dust impurities passes through the first cylinder 11 and enters the first cone cylinder 12. As the inner diameter of the first cone cylinder 12 decreases, the airflow generates an internal gas vortex attached to the external gas vortex, and the direction of the internal gas vortex is opposite to that of the external gas vortex, so that the dust impurities in the gas containing dust impurities enter the dust collecting tank 2 through the opening at the bottom end of the first cone cylinder 12, and the clean gas is discharged from the exhaust pipe 13 at the top of the first cylinder along with the internal gas vortex.
