Centrifugal-type oil smoke purifying air blower

Abstract

The invention discloses a centrifugal-type oil smoke purifying air blower. The centrifugal-type oil smoke purifying air blower comprises an enclosure, a biaxial stretching motor, a left impeller, a right impeller, a left volute tongue, a right volute tongue, an oil collecting box and a non-return plate, wherein the bottom of the enclosure is a V-shaped bottom; left and right oil outlets are formed in the V-shaped bottom; a middle partition plate is arranged in the enclosure for separating the enclosure into symmetrical left and right chambers; volute tongues, volute shells and a flue are arranged in the left and the right chambers; radial sections of the volute shells and the flue are shaped like a great V; the left and the right volute tongues are detachable volute tongues; front and rear trapezoidal notches are respectively formed in front and rear bottom parts of the volute tongues; a bump is arranged above the front trapezoidal notch. Compared with the prior art, the centrifugal-type oil smoke purifying air blower has the advantages of being good in oil smoke purifying effect and oil collecting effect, simple to maintain, and convenient to clean.

Description

technical field [0001] The invention relates to a centrifugal fan, in particular to a centrifugal fan for purifying oil fume. Background technique [0002] The patent publication number is CN201850C discloses a kitchen oil fume purification technology, which comprehensively filters the oil fume through three means of chemical solvent cleaning, high-voltage electrostatic purification and activated carbon filtration, and finally obtains clean air without peculiar smell. , the structure is too complex. The publication number is CN101327400 B, which discloses a three-layer filtration through ultraviolet photochemical oxidation, wet water spray and honeycomb activated carbon adsorption to achieve the effect of purifying oil fumes. Although the structure is simplified, both patents have the ability to replace chemical solvents and waste water To deal with new problems, the actual use and maintenance costs are high, which is not conducive to promotion. [0003] Therefore, it is a...
