Secondary cyclone separation assembly capable of flowing from multiple cones to single cone and dust collector

Abstract

The invention discloses a secondary cyclone separation assembly for flowing from multiple cones to a single cone and a dust collector, and relates to the technical field of purification and dust removal. Comprising a second-stage cone and a plurality of first-stage cones; a secondary cone air outlet pipe is arranged at the top of the secondary cone; a plurality of secondary cone air inlet pipes are uniformly arranged on the side wall of the secondary cone; the number of the secondary cone air inlet pipes is the same as that of the primary cones; a first-stage cone air outlet pipe is arranged at the top of the first-stage cone; a first-stage cone air inlet pipe is arranged on the side wall of the first-stage cone; the first-stage cone air inlet pipe is tangent to the first-stage cone side wall; the first-stage conical air outlet pipe is connected with the second-stage conical air inlet pipe through a connecting pipe; and dust collection boxes are arranged at the bottoms of the first-stage cone and the second-stage cone. By adopting the scheme that multiple cones move to a single cone, the structure is simple, the pressure drop loss is low, the noise is low, the efficiency durability is high, and the maintenance cost is low.

Description

technical field [0001] The invention relates to the technical field of purification and dust removal, in particular to a secondary cyclone separation assembly and a vacuum cleaner that flow from a multi-cone to a single-cone. Background technique [0002] In the existing secondary separation components based on the principle of cyclone separation, the primary structure is usually composed of one or more cones, and the secondary structure is usually a cone or a plurality of cones with a similar size attached to the primary structure. Small cones (for example, the first stage consists of one cone and the second stage consists of multiple cones around the first stage cone); the dust-laden airflow is purified from the cone and flows to the second stage cyclone cone, after purification by the second stage cyclone cone The clean air flows together from the air outlet; take the first-stage cone as one second-stage cone as an example, the air flow out of the first-stage cone air out...

[0002] In the existing secondary separation components based on the principle of cyclone separation, the primary structure is usually composed of one or more cones, and its secondary structure is usually a cone or multiple cones of the same size attached to the primary structure. Small cones (for example, the first stage consists of one cone, and the second stage consists of multiple cones surrounding the first cone); the dusty air flow is purified from the cone and then flows to the second cyclone cone, after being purified by the second cyclone cone The clean air flows together and flows out from the air outlet; taking the first-stage cone as one second-stage cone as an example, the airflow flowing out of the first-stage cone air outlet is divided into multiple branches and flows to each second-stage cone air inlet respectively; To make the secondary cone achieve higher separation efficiency, the wind speed flowing into the secondary cone is required to be extremely high to obtain sufficient centrifugal force, so the size of the secondary cone is usually much smaller than that of the primary cone (if the secondary cone has only one cone, the size is the same as The first-stage cone is equivalent), which leads to more severe friction between the airflow and the inner wall of the cone during the movement of the second-stage cone, and a large loss of resistance along the way and local resistance, resulting in a huge pressure drop loss in the current second-stage cone structure, and high noise
