Description

Technical Field

[0001] This utility model relates to the technical field of range hood accessories, and in particular to a high-efficiency vortex-type oil fume separator. Background Technology

[0002] Traditional range hoods generally use physical filtration to separate oil fumes, primarily relying on multi-layered metal filters or polymer adsorption materials to intercept the fumes. While this technology can achieve basic oil separation, it has significant drawbacks in practical applications: with increased use, grease condenses on the filter surface, forming a dense layer of dirt that gradually clogs the airflow channels. Recent advancements in vortex separation technology utilize centrifugal force generated by high-speed rotating components to separate oil mist, such as the three-dimensional dynamic interceptor described in patent CN201810128305.9, which employs synchronously rotating separation wheels and radial separation ribs. However, the cylindrical air-breaking bar in the center of existing designs has significant technical limitations: its smooth surface and symmetrical structure result in only linear airflow splitting, failing to create an effective turbulent adsorption effect and thus hindering effective oil adsorption, requiring further improvement. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a high-efficiency vortex-type oil fume separator.

[0004] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a high-efficiency vortex-type oil fume separator, including at least two separating wheels; several separating wheels rotate coaxially; separating ribs are arranged radially between the inner and outer rings of the separating wheels; air-breaking zones are formed by vertical and horizontal spacing between two adjacent separating wheels; air-breaking structures are arranged along the air-breaking zones;

[0005] The air-breaking structure includes connecting columns and air-breaking rod assemblies; the connecting columns are disposed on the inner and outer rings of the separating wheel; and the air-breaking rod assembly is disposed between the two connecting columns.

[0006] The wind-breaking rod assembly includes two adjacent wind-breaking inclined plates; the wind-breaking rod assembly is arranged vertically or horizontally in the wind-breaking zone; the two wind-breaking inclined plates form a V-shaped air passage.

[0007] Optionally, the wind-breaking rod assembly is arranged laterally in the wind-breaking zone; the two ends of the two wind-breaking inclined plates are respectively connected to the inner and outer connecting posts of the separating wheel.

[0008] Optionally, the air passage forms an air inlet on the side with a smaller spacing and an air outlet on the side with a larger spacing; when multiple separating wheels rotate coaxially, the inclined surfaces of the two air-breaking inclined plates form an air-blowing surface and create negative pressure at the air outlet.

[0009] Optionally, multiple sets of the windbreak rod assembly are provided at intervals along the vertical or horizontal direction.

[0010] Optionally, multiple air-breaking structures are evenly arranged along the circumference of the separating wheel.

[0011] Optionally, eight air-breaking structures are evenly arranged along the circumference of the separating wheel.

[0012] Optionally, the wind-breaking inclined plate has a flat plate, an arc-shaped plate, or a wavy plate structure.

[0014] Optionally, another separation wheel may be attached to the separation wheel; the separation ribs of the two adjacent separation wheels are correspondingly arranged to form a V-shaped air passage gap.

[0015] The beneficial effects of this invention are as follows: Through the synergistic design of the V-shaped air-breaking inclined plate and the multi-layer separation wheel, the oil fume separation efficiency and system stability are significantly improved. The V-shaped air passage, through its asymmetric guiding effect, creates a strong turbulent flow field in the air-breaking zone, promoting efficient collision and adsorption of oil mist particles with the surface of the separation ribs. The inclined plate air-breaking component forms a stepped oil film peeling path, effectively suppressing the secondary entrainment of oil by high-speed airflow, thus improving the oil collection rate.

[0028] Example

[0029] Reference Figures 1 to 4 The present invention proposes a high-efficiency vortex-type oil fume separator, comprising at least two separating wheels 10; several separating wheels 10 rotating coaxially; separating ribs 11 arranged radially between the inner and outer rings of the separating wheels 10; air-breaking zones formed by vertical spacing between two adjacent separating wheels 10; and air-breaking structures 20 arranged along the air-breaking zones.

[0030] The wind-breaking structure 20 includes a connecting column 21 and a wind-breaking rod assembly 22; the connecting column 21 is disposed on the inner and outer rings of the separating wheel 10; the wind-breaking rod assembly 22 is disposed between the two connecting columns 21;

[0031] The wind-breaking rod assembly 22 includes two adjacent wind-breaking inclined plates 221; the wind-breaking rod assembly 22 is arranged vertically or horizontally in the wind-breaking zone; the two wind-breaking inclined plates 221 form a V-shaped air passage 222.

[0032] In this invention, the synergistic design of the V-shaped wind-breaking inclined plate 221 and the multi-layer separation wheel 10 significantly improves the oil fume separation efficiency and system stability. The V-shaped air passage 222, through its asymmetric guiding effect, creates a strong turbulent flow field in the wind-breaking zone, promoting efficient collision and adsorption of oil mist particles with the surface of the separation ribs 11. The inclined plate wind-breaking component forms a stepped oil film peeling path, effectively suppressing the secondary entrainment of oil by high-speed airflow and improving the oil collection rate.

[0033] In some embodiments, the wind-breaking rod assembly 22 is arranged laterally in the wind-breaking zone; the two ends of the two wind-breaking inclined plates 221 are respectively connected to the two connecting columns 21 of the inner and outer rings of the separating wheel 10.

[0034] In this embodiment, the air passage 222 forms an air inlet on the side with a smaller spacing and an air outlet on the side with a larger spacing. When the multiple separating wheels 10 rotate coaxially, the inclined surfaces of the two air-breaking inclined plates 221 form air-blasting surfaces, creating negative pressure at the air outlet. By designing the air inlet of the V-shaped passage with a narrow spacing and the air outlet with a wide spacing, and by optimizing the inclination angle of the air-blasting surfaces, a local negative pressure zone is formed at the air outlet. This negative pressure effect accelerates the airflow through the gaps between the air-breaking ribs, enhancing the centrifugal oil-throwing effect; on the other hand, it causes the separated oil film to migrate directionally along the surface of the inclined plates to the oil collection tank through pressure difference adsorption.

[0035] In this embodiment, multiple sets of air-breaking rod assemblies 22 are arranged at intervals along the vertical or horizontal direction. The vertical arrangement of multiple sets of air-breaking rod assemblies 22 forms a layered turbulent flow field, with each layer corresponding to an oil mist concentration gradient in the airflow at different heights. This design can differentiate the capture of large particles sinking and small particles rising in rising oil fumes due to temperature stratification.

[0036] In this embodiment, multiple air-breaking structures 20 are evenly arranged around the circumference of the separator wheel 10. The even circumferential arrangement of the air-breaking structures 20 enables the separator to form a turbulent field of equal intensity in the 360° direction, eliminating the airflow imbalance phenomenon caused by traditional unilateral flow guidance.

[0037] Preferably, there are 8 wind-breaking structures 20 evenly arranged along the circumference of the separation wheel 10.

[0038] In this embodiment, the wind-breaking inclined plate 221 has a flat plate, an arc-shaped plate, or a wavy plate structure. In addition to the flat plate arrangement of the wind-breaking inclined plate 221, the wind-breaking inclined plate 221 can also be set in an arc-shaped plate or a wavy plate structure. The wavy or arc-shaped plate design of the wind-breaking inclined plate 221 can generate a periodic vortex street effect, causing the oil mist particles to undergo multiple directional changes near the plate surface, increasing the contact time with the separation rib 11.

[0039] In some embodiments, in addition to arranging the wind-breaking rod assembly 22 laterally, the wind-breaking rod assembly 22 can also be arranged vertically. The wind-breaking rod assembly 22 is arranged vertically in the wind-breaking zone; the upper and lower ends of the two connecting columns 21 are provided with crossbeam columns, and the two connecting columns 21 and the two crossbeam columns form a rectangular frame structure, with the wind-breaking rod assembly 22 vertically connected to the two crossbeam columns.

[0040] In this embodiment, another separation wheel 10 may be attached to the separation wheel 10; the separation ribs 11 of the two adjacent separation wheels 10 are correspondingly arranged to form a V-shaped air passage gap 12. The air passage gap 12 of the separation wheel 10 has the same function as the passage of the air-breaking component. Through the asymmetric guiding effect, the airflow forms a strong turbulent field, which promotes the efficient collision and adsorption of oil mist particles with the surface of the separation rib 11.

[0041] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
