Description

Filter wire tilting cooking fume filter
Technical field
The present invention relates to a kind of filter wire tilting cooking fume filter, specifically a kind of filter wire tilting cooking fume filter, category In family expenses and the field of air filtration of industry.
Background technology
One of the important source of Cooking Oil Fume as atmosphere pollution, the enough attention of people is not obtained but for a long time.Oil Cigarette is decomposed and the caused mist of oil based on liquid oil droplet and solid particle at high temperature by food and edible oil.It is oily in oil smoke Drop and particle diameter are about between 0.010~10 μm;Existing lampblack absorber uses screen pack and filter mode more, have individual layer or Multilayer, work principle of filter are to stop oil smoke by filter screen, but because filter sky is typically at 0.01 square centimeter, many drops in oil smoke Filter screen can be passed through not filter with particle, the pollutant that 1/3rd are there are about in oil smoke enters air, fails oil smoke sufficiently In pollutant be filtered dry completely.Therefore, the improvement of lampblack absorber is administered extremely urgent with fume pollution.
The content of the invention
In view of the above-mentioned problems of the prior art, in order to solve the shortcomings that above-mentioned prior art, the present invention provides a kind of Filter wire tilting cooking fume filter;The filter wire of winding is inclined design, realizes that drum has larger filter area, improves oil smoke Machine pumps filter, reduces greasy dirt to the pollution inside lampblack absorber.
To achieve these goals, the technical solution adopted by the present invention is:A kind of filter wire tilting cooking fume filter, including Drum inner ring, outer ring, filter wire and the spoke for connecting drum inner ring and outer ring, described outer ring groove, which has, is used for fixed put The groove of filter wire is put, described filter wire is wrapped in the annular region between disk inner ring and outer ring, direction and the outer ring axis of groove With angle of inclination, angle wound of the filter wire along groove slant.
Further optimization, described angle of inclination is 0-35 degree.
Further optimization, described angle of inclination is 9-13 degree.
It is further to optimize, there is the identical boss being arranged in order of several structures on described outer ring,
Further optimization, described boss is arranged on outer ring top, and radian is identical with the radian of outer ring, and the one of boss End is higher than its other end.
Further optimization, the peak of described boss and the difference in height of minimum point are 3-25mm.
Further optimization, the identical boss being arranged in order of described structure have head and afterbody, and height of head is more than Tail height, the head of each boss are connected with the afterbody of adjacent lands, and a closed bulge-structure is formed on outer ring.
Further optimization, described spoke sum are 3 to 9.
Further optimization, a diameter of 0.45mm of described filter wire.
Further optimization, the internal diameter of described inner ring is 45mm, and outer ring internal diameter is 280mm.
The filter of the present invention is arranged on rear side of filter screen of range hood and on front side of steam vent, when lampblack absorber works, drum Now also begin to high-speed rotation.Due to being wound with the preferable filter wire of lipophile, direction and outer ring of the filter wire along groove on drum Axis has an angle of inclination, and angle of inclination can be 2 degree, 3 degree, 10 degree, even bigger angle, such as 15 degree, 20 degree, this The design at kind angle of inclination causes filter wire to interweave closer, and filter wire is wrapped in drum both sides and mutually staggered, so as to realize drum There are larger filter area, good filtration effect, and drum one side is designed with rugged boss, it is only necessary to winding work together Filter wire on drum is divided into the filtering surface that multiple height differ by sequence can, can form a cylindrical filter space during filtering, Drum another side is filter wire height identical filter wire plane, can form almost closed filtration plane (in another side during filtering The number that filter wire occurs in a certain position 1s is about 10000 times), oil smoke is finally filtered, can will be small in oil smoke Oil droplet and particle filtering fall, and greatly improve lampblack absorber pumps filter.The beneficial effects of the invention are as follows:It can cross in filtering fume Molecule and oil droplet, improve the pumping-clean rate of filtering oil smoke, pollution of the oil smoke to environment can be substantially reduced.
