Abstract
The utility model discloses a filter screen of a smoke exhauster. The filter screen of the smoke exhauster is mounted at a place where an air suction hole of the smoke exhauster is located; the filter screen has a profile like a lug boss and is made of an integral mesh plate which is fully provided with punched holes and molded by drawing; the bottom surface of the filter screen is parallel with the top surface and is greater than the top surface; the bottom surface of the filter screen is provided with an opening which matches the air suction hole of the smoke exhauster; and the outer edge of the bottom surface of the filter screen is provided with an annular skirt plate which is in an integral structure with the filter screen. As the punched holes are directly punched on a metal plate and the filter screen is made of the integral mesh plate which is molded for once by drawing, the surface of the mesh hole of the filter screen is smooth, oil dirt is not easy to block and no oil dripping and leakage phenomenon exists; and due to the design of the lug boss shape, the filter screen of the smoke exhauster, disclosed by the utility model, has the advantages of guaranteeing a supply air rate of the smoke exhauster, great filtering area and low pressure reduction, improving intensity of the filter screen and prolonging the service life of the filter screen.
Description
Technical field
The utility model relates to a kind of lampblack absorber accessory, refers more particularly to the kitchen ventilator filtering net that a kind of intensity is high, filter area is large.
Background technology
In the prior art, the screen pack mesh of lampblack absorber has circle, square, hexagon, long lumbar hole shape etc.The filter screen mesh forms with braided steel wire, filter screen becomes planar shaped, cover the wind inlet place of lampblack absorber, such as China Patent No. CN201020108945.2, name is called the utility model patent of ventilator filtering screen, comprise fixed mount and filter screen, the fixed mount inboard arranges filter core, filter core edge and fixed mount are connected and fixed, and this apparatus structure is simple, and is easy to use, be installed in the place, inlet scoop of smoke exhaust ventilator during use, effectively alleviated the inboard phenomenon of hanging grease of smoke exhaust ventilator, but because screen pack is the plane, filter area is less, the compression strength of screen pack is not high and easy damage also, and range of application is narrower.
The utility model content
The utility model mainly solves the technical problem that common kitchen ventilator filtering net intake is low, filter area is little, mesh is easily stopped up by greasy dirt and intensity is little; A kind of intensity height, large, the smooth kitchen ventilator filtering net that is difficult for water clock oil of screen pack mesh of filter area are provided.
In order to solve the technical problem of above-mentioned existence, the utility model mainly is to adopt following technical proposals:
A kind of kitchen ventilator filtering net of the present utility model, be installed in the wind inlet place of lampblack absorber, described screen pack profile is boss-shaped, made by the whole web plate that is covered with punching and drawing and forming, the bottom surface of screen pack is parallel with end face and greater than end face, the bottom surface opening of screen pack also matches with the wind inlet of described lampblack absorber, the outer of screen pack bottom surface is provided with the annular shirt rim plate with the screen pack integrative-structure, described screen pack is contained on the wind inlet by the shirt rim integrated circuit board, the screen pack of boss-shaped, guaranteed the intake of cigarette machine, the screen pack filter area is large, and pressure drop is little, the separating degree of grease is good, boss structure has strengthened the compression strength of screen pack, and the whole web plate of punching press pore-forming and drawing and forming makes the mesh smooth surface be difficult for being stopped up by greasy dirt, grease separating degree is good and can not produce water clock oil.
As preferably, the mesh of described screen pack is square hole or diamond hole.
As preferably, the central authorities of described screen pack end face are provided with depression, and the direction of described depression is inboard towards boss, adopt the bulb-shaped recess design at end face, have both promoted the attractive in appearance of product, have also strengthened the compression strength of screen pack.
As preferably, described annular shirt rim plate is wide.
As preferably, described screen pack profile is quadrangular frustum pyramid shaped, good looking appearance.
As preferably, the outer of described annular shirt rim plate is provided with the flanging with annular shirt rim plate integrative-structure, and flanging has strengthened the intensity of annular shirt rim plate, has prolonged the service life of product.
As preferably, described annular shirt rim plate is provided with a bound edge, and described bound edge is notch, notch inwardly, the thickness of groove width and annular shirt rim plate matches, bound edge is installed on the annular shirt rim plate, strengthened the intensity of annular shirt rim plate, manufacture craft is simple, and cost is lower.
As preferably, the end face of described screen pack is circular, and the bottom surface of screen pack is square.
As preferably, the surface of described screen pack is provided with one deck non-sticking lining, and grease is not easy to stick on the screen pack, and easy to clean is quick.
The beneficial effects of the utility model are: screen pack adopts on sheet metal the whole web plate of direct punching press diamond hole and one-off drawing moulding to make, screen pack mesh smooth surface, greasy dirt is difficult for stopping up and can not producing the phenomenon of water clock oil, the design of boss-shaped, guaranteed the intake of cigarette machine, filter area is large and pressure drop is little, and the intensity of screen pack also is improved, and has prolonged the service life of screen pack.
