Three-stage cyclone separation dust collector

Abstract

The invention discloses a three-stage cyclone separation dust collector, which comprises an outer dust bucket, wherein the outer dust bucket is provided with an outer tangential air inlet; an inner dust bucket is arranged in the outer dust bucket; a screen barrel which corresponds to the outer tangential air inlet is arranged above the inner dust bucket; the inner dust bucket, the screen barrel and the outer dust bucket are enclosed into a first-stage cyclone cavity; a rotary barrel and a group of rotary conical barrels are sleeved in the screen barrel; an air inducing barrel is further arranged in a circle enclosed by the rotary conical barrels; the air inducting barrel is inserted into the rotary barrel; the upper end of the rotary barrel is provided with a second-stage tangential air inlet; the upper end of the rotary conical barrel is provided with a third-stage tangential air inlet; an air outlet cover covers the rotary conical barrel; the back face of the air outlet cover is provided with air outlet barrels which correspond to the rotary conical barrels; the air outlet barrels extend into the rotary conical barrels; a screen cover plate further covers the air outlet cover; the screen cover plate is filled with filter cotton. According to the three-stage cyclone separation dust collector, three-stage cyclone separation is adopted, so that dust is separated more completely, and separation and coarse dust and fine dust is realized; the first stage of a cyclone system adopts the screen barrel while the second stage adopts a single cone structure, so that the structure is simple, the cost is low, and a good effect is achieved.

Description

technical field [0001] The invention relates to a cyclone separation vacuum cleaner. Background technique [0002] The dust separation effect of the existing cyclone separation vacuum cleaner still needs to be improved, and the existing cyclone separation vacuum cleaner cannot realize the separation of coarse ash and fine ash. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing cyclone-separated vacuum cleaner, the present invention provides a three-stage cyclone-separated vacuum cleaner with better dust separation effect and the separation of coarse ash and fine ash. [0004] The technical solution of the present invention to solve the technical problem is: a three-stage cyclone-separated vacuum cleaner, including an outer dust bucket, the outer dust bucket has an outer tangential air inlet, and an inner dust bucket is also provided in the outer dust bucket , the lower end of the inner dust bucket is close to the bott...
