Abstract
The utility model discloses a filter plate installed on the lampblack presser, which comprises a front filter plate and a back filter plate fixed and connected with each other. The front filter plate is provided with multi-row air intakes, and the back filter plate is provided with multi-row air outlets, and the air intakes and the air outlets have a staggered interval arrangement. The edges of the air intakes and the air outlets of the front filter plate inwards extend to air intake flanging respectively. A filter screen is arranged between the front filter plate and the back filter plate; the design makes the air intake flanging of the air intake and the air outlet form a turned inlet channel, when the air carrying the oil smoke passes through the inlet channel, the heat can be absorbed by the flanging and the filter screen, and so the oil smoke can change from minimal oil drops to the liquid, and can be separated from the air. The tail gas can be discharge from the air outlet of the back filter plate to reach the purpose of separating the oil smoke. The product has simple structure, low manufacture cost, good oil smoke separating effect and small air resistance, which is favor of cleaning, and can be widely used for the installation of the lampblack presser.
Description
Technical field
The utility model relates to a kind of filter, particularly a kind of filter that is installed on the smoke exhaust ventilator.
Background technology
The cooking fume filter that uses on the smoke exhaust ventilator generally is network structure at present, the screen pack that promptly adopts wire netting or other material to make is placed on the passage of soot gas circulation, when soot gas passes through, oil smoke in the gas contacts with screen pack, its heat is filtered net and absorbs, oil smoke promptly condenses into liquid oil droplet attached on the screen pack, reaches the purpose of separating oil smoke.But because screen pack is made up of many apertures, most of oil smoke does not contact promptly with screen pack and directly passes through, thereby oil smoke separating effect and efficient are all relatively poor; Because separated oil droplet attached on the screen pack, has promptly blocked the aperture of screen pack in the course of time, make air drag become big, oil smoke separating effect reduction simultaneously, thereby cause the power consumption height, problems such as noise is big also are unfavorable for cleaning simultaneously, also are unfavorable for further improving the separating effect of oil smoke.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, the filter of oil smoke good separating effect.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of filter that is installed on the smoke exhaust ventilator, it comprises front filter plate and the rear filter plate that is mutually permanently connected, described front filter plate is provided with many row's air inlets, rear filter plate is provided with the gas ports of discharging more, air inlet and gas outlet are staggered to be spaced, the air inlet of front filter plate and the gas outlet edge air inlet crimping that extended internally respectively is provided with filter screen between described front filter plate and the rear filter plate;
As a modification of the embodiment above, described filter is camber; Described air inlet crimping is circular arc type;
As the further improvement to above-mentioned embodiment, the extension of the front end of described rear filter plate is provided with the fixedly coupler body of front filter plate, and described front filter plate and rear filter plate rear end are respectively arranged with screw mounting hole.
The beneficial effects of the utility model are: this product is spaced air inlet and gas outlet are staggered, thereby make the air inlet crimping on air inlet and the gas outlet form the inlet channel of transferring, when the air that carries oil smoke is crossed this inlet channel through this, heat is crimped and filter screen absorbs, oil smoke promptly becomes liquid by tiny oil droplets, from air, separate, tail gas is discharged from the gas outlet on the rear filter plate, reach the purpose of separating oil smoke, this product has simple in structure, and cost of manufacture is low, the oil smoke good separating effect, air drag is little, be beneficial to cleaning, thereby be widely used in installing of smoke exhaust ventilator.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cut-away view of Fig. 1;
Fig. 3 is a structure broken away view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of filter that is installed on the smoke exhaust ventilator, it comprises front filter plate 1 and the rear filter plate 2 that is mutually permanently connected, described front filter plate 1 is provided with many row's air inlets 11, rear filter plate 2 is provided with the gas ports 21 of discharging more, air inlet 11 and gas outlet 21 staggered being spaced, the air inlet 11 of front filter plate 1 and the gas outlet 21 edges air inlet crimping 4 that extended internally respectively, described air inlet crimping 4 is circular arc type, can also be set to other shape certainly; Between front filter plate 1 and the rear filter plate 2 filter screen 5 is set, filter screen 5 can use nut or be weldingly fixed in the filter, and in order to cater to the airintake direction of oil smoke, described filter is the camber design.
This product is for the ease of installing and fixing, and the front end extension of described rear filter plate 2 is provided with the fixedly coupler body 22 of front filter plate 1, and described front filter plate 1 and rear filter plate 2 rear ends are respectively arranged with screw mounting hole 12,23.
The operation principle of this product is: when oil smoke when many rows air inlet 11 of front filter plate 1 enters filter, because air inlet 11 and gas outlet 21 staggered being spaced, thereby make the air inlet crimping 4 on air inlet 11 and the gas outlet 21 form the inlet channel of transferring, when the air that carries oil smoke is crossed this inlet channel through this, heat be crimped 4 and filter screen 5 absorb, oil smoke promptly becomes liquid by tiny oil droplets, from air, separate, tail gas is discharged from the gas outlet 21 on the rear filter plate 2, reach the purpose of separating oil smoke, this product has simple in structure, cost of manufacture is low, the oil smoke good separating effect, air drag is little, be beneficial to cleaning, thereby be widely used in installing of smoke exhaust ventilator.
