Abstract
The invention relates to the technical field of air purifying devices for removing dust and oil, and in particular relates to an oil slinging blade for an oily fume purifier and a manufacturing method thereof. The oil slinging blade comprises a center disc and a plurality of rectangular flat vanes, wherein the vanes takes the center disc as a center to be radially distributed. One end of each vane is fixedly connected to the center disc, the end of each vane, fixedly connected to the center disc, is defined as a fixed end, and the other end is defined as a free end. The oil slinging blade adopts the rectangular vanes with a sheet structure to replace the current steel wire rod structure. When the oil slinging blade of the oily fume purifier rotates, the vanes form an air guiding form in the rotating process. As the contact area of the vane with the sheet structure is large, an intercept surface to oily fume passing through the oil slinging blade is increased, and the intercept rate to airflow such as oily fume is also increased. Therefore, the purifying efficiency of the oil slinging blade to the airflow such as oily fume is increased, and the purifying effect is good.
Description
Technical field
The present invention relates to dedusting, except wet goods cleaner air package technical field, more specifically, relate to and get rid of alopecia areata leaf and manufacture method thereof for cooking fume remover.
Background technology
In recent years, people's living standard improves constantly, and healthy and environmental consciousness strengthens day by day, and people thirst for having a health, clean, the family kitchen environment of environmental protection.Simultaneously, catering industry is also flourish, and it has brought into play positive effect bringing about a prosperous economy, improve aspect living standard.But the cooking fume in family kitchen and food and drink hotel increasingly sharpens to the pollution of peripheral resident living environment.In prior art, as the interception clarifier on dedusting air cleaning device, mainly contain two kinds of structures at present.
The first structure is the dynamic oil smoke clarifier, it comprises wheel skeleton and wire, described wire generally adopts steel wire or the B alloy wire that diameter is 0.1 ~ 0.2mm, be wrapped in described the wheel on skeleton by certain requirement, the concrete structure of this dynamic physical shielding purifier and winding method can be referring to the preparation methods of the disclosed dynamic physical shielding purifier of Chinese patent literature CN200984483Y and the disclosed air dust centrifugal purifier of Chinese patent literature CNl01028575A and rotary filter net disk thereof.The defect of the dynamic physical shielding purifier of this structure is apparent.First, because this dynamic physical shielding purifier comprises wheel skeleton and wire, and the wheel skeleton is to make of aluminum alloy materials, its cost is higher, in addition, each is taken turns skeleton and at least comprises the spoke more than 6, and spoke itself can produce windage to the air intake of air assembly, affects the purifying rate of air assembly; In addition, the wire of this clarifier is wrapped on the wheel skeleton, and because needs are wrapped in wire on the wheel skeleton, described diameter wiry can not be too thick, generally is 0.1 ~ 0.2mm, otherwise wire diameter too slightly just can't be wound around; The second, because wire is thinner, so the wire that there will be the clarifier easy loose and problem that disconnects at high temperature causes the service life of clarifier short; The 3rd, when being wound around, on the cylindrical of its center at clarifier and wheel skeleton, can form cross-like due to wire, oil smoke very easily forms obstruction, not easy cleaning at this two place; The 4th, because wire is thinner, its probability of interception to the particle in waste gas is less, therefore purifying rate is low, weak effect and adaptive surface are narrow.
The structure of the second clarifier,, by the method for punching press, one circular plate object is radially had to groove along it, make the part between two grooves become spoke, a plurality of spokes distribute and form successively on the periphery of plate object, and particular content can be referring to Chinese patent literature CN2901109Y.The subject matter of the dynamic physical shielding purifier of this structure is that purifying rate is very low, and windage is large, and the practical application function is very micro-.This is that when front is plane, its windage is large, has reduced the purifying rate of clarifier because the front of the spoke of the dynamic physical shielding purifier of this structure and two side are plane; And its side is plane, when the clarifier High Rotation Speed, side can produce pressure to the waste gas of coming in from frontal, under the effect of side, make waste gas along with the clarifier direction of rotation flows, and the contacted chance of the particle in waste gas and spoke is less, so purifying rate is low.
