Technical Field

The utility model belongs to the technical field of waste gas treatment in the casting industry, and particularly relates to an adjustable cyclone dust collector.

Background

In the dust-containing waste gas treatment process, when the dust-containing waste gas is pumped into the cyclone dust collector by the centrifugal fan, the dust-containing waste gas can rotate from top to bottom along the wall. The dust particles are thus separated from the gas flow by centrifugal force and fall by gravity along the wall into the hopper, while the gas is discharged from the discharge pipe in an upward direction by rotation along the discharge pipe.

The cyclone dust collector is a dry type filtering dust collector, each part has a certain size proportion, and the efficiency and the pressure loss of the cyclone dust collector can be influenced by the change of each proportion relation, wherein the diameter of the dust collector, the size of an air inlet, the diameter of an exhaust pipe and the insertion depth of the exhaust pipe are main influencing factors. With the increasing requirement of dust removal, the cyclone dust collector with the prior structure is composed of an exhaust pipe interface 1, a fixed exhaust pipe 2, an air inlet pipe 3, a cylinder 4, a cone 5 and an ash bucket 6 as shown in figure 1.
