Embodiment 1

[0042] An oil fume separation component for eddy current separation of oil fume, such as Figures 1 to 4 As shown, a device main body, a vortex generating device group 14 and a plurality of eaves structures 13 are provided, and the vortex generating device group 14 and a plurality of eaves structures 13 are respectively fixedly installed on the device main body. The side facing the ground when the oil fume separation assembly 1 is installed is defined as the bottom, and the vortex generating device group 14 is fixedly mounted on the main body of the device and located on the upper surface of the eaves structure 13 .

[0043] The main body of the device is provided with a plurality of concentric tubes 11 with coincident central axes and connecting shafts 12, and the connecting shafts 12 are fixedly connected to one ends of the plurality of concentric tubes 11 respectively. The eaves structure 13 is arranged around and fixedly mounted on the other end of the concentric tube 11 ....

Embodiment 2

[0060] An oil fume separation assembly for eddy current separation of oil fume, other features are the same as in embodiment 1, the difference is that n=4 in this embodiment, that is, there are four concentric tubes 11 in this embodiment. In this embodiment, m=2, that is, two sets of vortex generators 14 are provided, one is provided in the fourth concentric tube, and the other is provided in the third concentric tube. At the same time, the concentric tubes 11 in this embodiment correspond to the eaves structures 13 one by one.

[0061] Compared with Example 1, the oil fume separation assembly for eddy current separation oil fume has an additional concentric tube 11, that is, the space volume of the oil fume separation assembly 1 is increased, thereby reducing the area of ​​the lower part of the concentric pipe 11, increasing the gas entering speed, and increasing The pressure difference between the interior of the concentric tube 11 and the exterior space can increase the sep...

Embodiment 3

[0063] A range hood, such as Figure 5 and Figure 6 As shown, the range hood has the oil fume separation assembly 1 described in Embodiment 1 above. The range hood is also provided with an oil collecting device 3 , a casing 2 and an exhaust assembly 4 , the oil fume separation assembly 1 is assembled inside the casing 2 , the oil collecting device 3 is assembled at the bottom of the casing 2 , and the exhaust assembly 4 is fixedly assembled inside the casing 2 And it is located directly above the oil fume separation assembly 1 .

[0064] The casing 2 is provided with a plurality of casing air inlets 21 and an annular sheet 22 matching the plurality of casing air inlets 21. The annular sheet 22 is integrally connected to the corresponding inner surface of the casing 2 and is located on the edge of the casing air inlet 21, The annular piece 22 is in one-to-one correspondence with the air inlet 21 of the housing. The annular piece 22 of the present invention can also be fixedl...

Abstract

The invention discloses a lampblack separation assembly for vortex separation of lampblack. The lampblack separation assembly is provided with a device main body, a vortex generation device group anda plurality of entablature structures, wherein the vortex generation device group and the plurality of entablature structures are respectively and fixedly arranged on the device main body; when the lampblack separation assembly is mounted, one side, facing the ground, is defined as the lower part; the vortex generation device group is fixedly assembled on the device main body and is positioned onthe upper surfaces of the entablature structures. According to the lampblack separation assembly, vortex of lampblack gas can be generated inside the vortex generation device group, the entablature structures and a concentric tube, and thereby lampblack particles are separated. According to the range hood, firstly, the lampblack gas generates vortex inside, most lampblack particles are separated,gas with small amount of lampblack particles is left, the rest lampblack particles are centrifugally separated by an exhaust component, and eventually clean gas is exhausted to the outside. By use ofthe range hood, the contact between high-concentration lampblack gas and the exhaust component can be avoided and the cleanness of the exhaust component is effectively ensured.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to an oil fume separation assembly for eddy current separation of oil fume and a range hood with the oil fume separation assembly. Background technique [0002] In the prior art, the separation of soot particles in the range hood is mainly carried out by the wind wheel. The principle of action is that the rotation of the wind wheel drives the soot gas to generate centrifugal force during the rotation of the soot particles, so that the soot particles are thrown to the inner wall of the volute and flow to the range hood. The oil collecting device of the machine. However, the oil fume separation ability of the wind wheel is low and the effect is low, only a small part of the oil fume particles can be removed, and a large number of oil fume particles remain in the discharged gas, which is easy to cause air pollution. [0003] Therefore, aiming at the deficiencies of the prior art, it is very...
