The invention relates to the technical field of purification and dust removal, in particular to a multi-cone flow-to-single-cone secondary cyclone separation assembly and a dust collector.
Background
The prior secondary separation assembly based on the cyclone separation principle has a primary structure which is generally composed of one or more cones, and the secondary structure is generally a cone or a plurality of cones with smaller sizes which are attached to the primary structure (for example, the primary structure is composed of one cone, and the secondary structure is composed of a plurality of cones which surround the primary cone); the dust-containing air flow flows to the secondary cyclone cone after being purified in the cone, and the clean air flow after being purified by the secondary cyclone cone is collected together and flows out of the air outlet; taking a primary cone as a secondary cone as a plurality of secondary cones as an example, dividing airflow flowing out of an air outlet of the primary cone into a plurality of branches and respectively flowing to an air inlet of each secondary cone; in order to achieve higher separation efficiency, the wind speed flowing into the secondary cone is required to be extremely high to obtain enough centrifugal force, so that the size of the secondary cone is usually much smaller than that of the primary cone (if only one secondary cone is provided, the size of the secondary cone is equivalent to that of the primary cone), the airflow is more severely rubbed with the inner wall surface of the cone in the motion process of the secondary cone, the on-way resistance and the local resistance loss are great, the pressure drop loss of the current secondary cone structure is extremely great, and the noise is high.

In order to achieve the above purpose, the invention provides a secondary cyclone separation assembly flowing from multiple cones to single cones, comprising a secondary cone and a plurality of primary cones; the top of the secondary cone is provided with a secondary cone air outlet pipe; 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 primary cone air outlet pipe is arranged at the top of the primary cone; the side wall of the primary cone is provided with a primary cone air inlet pipe; the primary cone air inlet pipe is tangent to the side wall of the primary cone; the primary cone air outlet pipe is connected with the secondary cone air inlet pipe through a connecting pipe; dust collection boxes are arranged at the bottoms of the primary cone and the secondary cone.
Further, a branch pipeline is connected to the primary cone air inlet pipe; the tail ends of the branch pipelines are connected with the branch pipelines; an air inlet is arranged on the shunt pipeline.
Further, the number of the primary cones is n, and the length, width and height dimensions of the secondary cones are 1-n/2 times of those of the primary cones.
Further, the number of the primary cones is 2-20.

1. based on the scheme that multiple cones move towards a single cone, the air flow design flowing out of the multiple cones respectively flows into the single cone uniformly in the circumferential direction, so that the entering air of the secondary cone is uniform, the strength of turbulent flow is reduced, and the separation efficiency of the secondary cone is improved;
2. because the primary cone is used as the primary dust removal, the excessive high dust removal efficiency is not required, so that the excessive high wind speed is not required, the primary multi-cone flows to the secondary single cone, and even under the condition of properly enlarging the size of the secondary cone, the wind speed in the secondary cone is larger than that of the primary cone, thereby being beneficial to generating the higher centrifugal force and improving the separation efficiency of the secondary cone; the secondary cone has larger size, so that excessive resistance loss is avoided;
3. the secondary cone has only one, so that even if one or a plurality of efficiency of the primary cone is reduced, the gas flowing out after the purification of the secondary cone can keep extremely high dust removal efficiency; if the total dust removal efficiency is reduced, except for the extreme case that the generation efficiency of a certain primary cone is greatly reduced, only the secondary cone is needed to be checked in a targeted manner, so that the maintenance is convenient;
4. simple structure, low pressure drop loss, low noise, strong efficiency durability and low maintenance cost.
