Description

Cooking fume filtering plate

Technical field

The utility model relates to a kind of filter, particularly the cooking fume filtering plate that the oil smoke in the gas can be separated.

Background technology

The cooking fume filter that uses generally all is a 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, also be unfavorable for simultaneously cleaning, also be unfavorable for further improving the separating effect of oil smoke.

The utility model content

Have cooking fume filter oil smoke inferior separating effect now in order to overcome, the deficiency that air drag is big, the utility model provides a kind of good separating effect, the cooking fume filtering plate that air drag is little

The technical scheme that its technical problem that solves the utility model adopts is: a kind of cooking fume filtering plate, it is characterized in that: it comprises header board and back plate, header board and back plate are separated with distance between being oppositely arranged also, header board is provided with air inlet, back plate is provided with the gas outlet, and air inlet and gas outlet are staggered to be spaced.

The beneficial effects of the utility model are, simple in structure, cost of manufacture is low, the oil smoke good separating effect, air drag is little, be beneficial to cleaning, and can be according to different use occasions, and the methods of stacked many group cooking fume filtering plates further improve the oil smoke separating effect before and after adopting, experiment showed, that purifying rate to the oil smoke that passes through is greater than 80%.

Fig. 2 is the local amplification view of Fig. 1 along the A-A direction.

Fig. 3 is the front view of the another kind of embodiment of the utility model cooking fume filtering plate.

Fig. 4 is the front view of another embodiment of the utility model cooking fume filtering plate.

The specific embodiment

As shown in Figure 1 and Figure 2, cooking fume filtering plate of the present utility model comprises header board 1 and back plate 2, and header board 1 and back plate 2 are separated with distance between being oppositely arranged also, and header board 1 is provided with air inlet 3, and back plate 2 is provided with gas outlet 4, air inlet 3 and gas outlet 4 staggered being spaced.Header board 1 and back plate 2 adopt metallic plate to make, and make better effects if with aluminium sheet.Air streams the air that contains oil smoke and whirlpool owing to the factors such as variation of volume space form when entering air inlet 3, because the flow velocity of air and stream double action with whirlpool, make airborne oil smoke under inertia force and action of centrifugal force, thrown to cooking fume filtering plate, the heat of oil smoke is absorbed by cooking fume filtering plate, oil smoke condenses into promptly that tiny oil droplet is separated and attached on the cooking fume filtering plate, finishing for the first time, oil smoke separates; Simultaneously, because air inlet 3 and gas outlet 4 are adopted and are spaced, the variation that flows to takes place and turns back in air in by the process of cooking fume filtering plate, the air of formation is streamed with whirlpool to be strengthened, under the double action of inertia force and centrifugal force, airborne oil smoke is thrown to cooking fume filtering plate once more, and finishing for the second time, oil smoke separates.

Embodiment: as shown in Figure 1 and Figure 2, cooking fume filtering plate of the present utility model comprises header board 1 and back plate 2, and header board 1 and back plate 2 are separated with distance between being oppositely arranged also, and header board 1 is provided with air inlet 3, back plate 2 is provided with gas outlet 4, air inlet 3 and gas outlet 4 staggered being spaced.The edge of air inlet 3 also is provided with front wing panel 5, the edge of the gas outlet 4 of back plate 2 also is provided with rear fender 6, air inlet 3, front wing panel 5, form the air inlet channel 7 of turnover suddenly between rear fender 6 and the gas outlet 4, adopt the structure of above inlet channel 7 can guarantee and strengthen the angle of air flow turnover, it is more abundant that air is streamed with the formation of whirlpool, also can regulate the flow velocity of air simultaneously, make that oil smoke is easier when air flow changes, to be thrown to cooking fume filtering plate by inertia force and centrifugal force by changing distance between front wing panel 5 and the rear fender 6.The top 8 of front wing panel 5 and the top of rear fender 69 are sharp keen seamed edge, make that air is that streaming with whirlpool intensity of formation is bigger by this place, thereby have increased the probability that oil smoke contacts with cooking fume filtering plate greatly, have improved the separative efficiency of oil smoke greatly.Angle α between front wing panel 5 and the header board 1 is 30～150 °, and the angle β between rear fender and the back plate is 30～150 °, and preferably angle α equates with angle β and is 60～120 °.

The air inlet 3 of above-mentioned cooking fume filtering plate and gas outlet 4 are strip, and front wing panel 5 is arranged on the edge on the long limit of strip air inlet 3, and rear fender is arranged on the edge on the long limit of strip gas outlet 4.Air inlet 3 and gas outlet 4 also can be shape size adaptive circular hole, slotted eye or square holes mutually, and as shown in Figure 3, this moment, then front wing panel 5 was arranged on the periphery edge place of air inlet 3, and rear fender 6 is arranged on the periphery edge place of gas outlet 4.As shown in Figure 1 and Figure 4, the outline of the air intake surface formed of each bar strip air inlet 3 can be rectangle, square, circle or ellipse etc.In like manner, the outline of the air intake surface formed of the air inlet 3 of each circular hole, slotted eye or square hole shape also can be rectangle, square, circle or ellipse etc.

In order further to improve the separating effect of oil smoke, can will organize the cooking fume filtering plate stacked use in front and back or the use that is combined into one according to different use occasions or environmental requirement employing more, make its structure compact more, thereby making the process filtered air contain the oil smoke amount reduces greatly, to satisfy different use occasions or environmental requirement, experiment showed, the fume purifying rate by air greater than 80%, can be applicable to the occasion of various fume purifyings, as family kitchen, restaurant, restaurant etc.
