Abstract

The utility model relates to a device for realizing wash free of cooking-fume exhauster using centrifugal net of absorption materials. A centrifugal frame is arranged on the shaft of a motor and equipped with a centrifugal net of absorption materials such as non woven; the centrifugal net rotates along with the same directions of the motor and a wind wheel in order to make the oil(solid or liquid) separate fully from smoke(gas) and finally achieve the object of the wash free of cooking-fume exhauster.

Description

Realize the device that smoke exhaust ventilator exempts to clean with the sorptive material centrifugal network

The utility model belongs to a kind of and realizes the oil smoke separating purifying device that smoke exhaust ventilator exempts to clean with the sorptive material centrifugal network.

The cleaning problem of smoke exhaust ventilator is the headache problem that troubles manufacturer and user always.The way that a few days ago addresses this problem is summed up to be had: (1), install automatic scavenging pump additional, because of DeGrain does not have to popularize; (2), widely used be to add the static wire netting of one to multiple layer, plastic wire, non-woven fabric net, filter paper etc. at air inlet, certain effect is arranged, but still need regularly to clean, and screen pack itself is very easily dirty, has increased new cleaning worry again; Sticking oil is too much inflammable; (3), be that the metal of representative revolves the net purifier with patent No. ZL97249022, ZL97251560, ZL98202073.2, ZL99203855, ZL99237006 etc., although have the practical effect that tangible oil smoke separates and realization smoke exhaust ventilator long-time (2-3 years) need not clean, but still need clean behind the 2-3, illustrate that the effect of filtration, purification is still not thorough; Screen pack itself more need regularly be scrubbed.And can decay intake more than 10% during actual the use, smoke discharging effect also is a greater impact.

The purpose of this utility model is: design a kind of can not influence intake disposable, basically, to oil smoke isolation of purified oil smoke separating purifying device more completely, and realize the ideal effect that smoke exhaust ventilator only needs operational maintenance, need not clean all the life.

For achieving the above object, the technical solution of the utility model is: install one centrifugal on motor shaft, the centrifugal filtration net is housed on centrifugal, it is characterized in that: the centrifugal filtration net is to make with sorptive materials such as the above non-weaving cloth of one deck (also being nonwoven), filter paper.Centrifugal is to make with metal or plastics, and its diameter is less than the diameter of wind cabinet (inner bag) 1, is fixed on the motor shaft with button oppositely is installed, or itself makees reverse installation button and motor shaft is installed with centrifugal; Screen pack adopts the most practical most economical way---and do the closing in of screen pack with elastic cord or fine rule rope, again filtration net cover (also can directly be enclosed within on the centrifugal impeller existing smoke exhaust ventilator) on centrifugal; Also can adopt other methods more attractive in appearance that screen pack and centrifugal are made up installation.In order to increase the intensity of screen pack, can be on sorptive material screen packs such as nonwoven, the filter paper surface longitudinal and transverse several diatoms (promptly handling) that roll with pin felt method.Driven by motor wind wheel, centrifugal, the equidirectional rotation of screen pack, make liquid greasy dirt be filtered the centrifugal filtration of net height speed, drain, solid-state greasy dirt is that carbon distribution is delayed on the screen pack basically, and gas is discharged to outdoor, and oil (solid, liquid) cigarette (gas) is real to be separated, purify thereby make.Use this to install visualized result to be: fuel-displaced many---show that smoke discharging effect is good; Oil is rare---not sticking substantially greasy dirt in impeller and the inner bag; The disposable filtering net can regularly replace, and also can wash the back and continue to use; Finally make smoke exhaust ventilator realize to unpick and wash all the life, only needing the purpose of operational maintenance!

The utility model has the advantages that 1. simple in structure, can be applied directly on the existing various smoke exhaust ventilator! 2. screen pack can disposablely use, and promptly dirtyly promptly abandons; Also can wash the back continues to use; 3. oil smoke isolation of purified effect is than the screen pack of no adsorptivity more thorough (use metal mesh filter when cooking bean curd and use weaving cloth or nonwoven filtration to have identical reason), and has air permeability and good, do not influence intake and smoke discharging effect; 4. finally make smoke exhaust ventilator realize to unpick and wash all the life, only need operational maintenance!

So realistic meaning of the utlity model has.

Below in conjunction with the drawings and specific embodiments the utility model is described further.The utility model is applicable to axial-flow type and centrifugal smoke exhaust ventilator, this only a centrifugal smoke exhaust ventilator be described for embodiment.

The embedded adsorptivity centrifugal network of Fig. 1 oil smoke separating purifying device

Fig. 2 cover type adsorptivity centrifugal network oil smoke separating purifying device

Fig. 3 is a centrifugal schematic diagram: 10 are annulus, and 11 is the nut that button oppositely is installed.

Embodiment one (referring to Fig. 1): embedded adsorptivity centrifugal network oil smoke separating purifying device

On the motor shaft 4 of the motor 3 of smoke exhaust ventilator, be equipped with centrifugal 5, centrifugal 5 itself is served as reverse installation button again, makes centrifugal 5 and motor shaft 4 is installed together.Centrifugal 5 is the capable or polygon annular of annulus, and its diameter is not more than the air inlet diameter of wind cabinet (inner bag) 1.Put the centrifugal filtration net 6 of sorptive material on centrifugal 5 annulus or polygon ring 10, centrifugal filtration net 6 is that nonwoven, filter paper of flame treatment etc. made, and rolls several diatoms in length and breadth to gain in strength on wire side.Centrifugal filtration net 6 usefulness elastic cords or fine rule rope are done and are closed up 7, are beneficial to periodic replacement.Motor 3 drives wind wheels 2, centrifugal 5 and centrifugal filtration net 6 is made centrifugal motion, and liquid greasy dirt is intercepted by centrifugal filtration net 6 and centrifugally flows away at wind cabinet (inner bag) 1; Solid-state carbon distribution, dust etc. all are delayed on the centrifugal filtration net 6; Gaseous state is discharged to outdoor.Centrifugal filtration net 6 needed 2-3 month to change (or cleaning) once, with the result of use of assurance exhaust air rate and screen pack, thereby guaranteed the result of use that smoke exhaust ventilator only need maintain, need not clean.

Embodiment two (referring to Fig. 2) cover type adsorptivity centrifugal network oil smoke separating purifying device

4 is the motor extension shaft, 5 for centrifugal, oppositely button is installed, 6 for annulus overlaps screen pack, 8 is oil drain pan.Other positions and work situation are with Fig. 1 and embodiment one.Require: the rack diameter of centrifugal filtration net 6 conveniently is advisable to change the centrifugal filtration net less than the diameter 1-2 centimetre of oil drain pan 8.

Claims

A kind of device of exempting to clean with sorptive material centrifugal network realization smoke exhaust ventilator, on motor shaft, install one centrifugal, the centrifugal filtration net is housed on centrifugal, it is characterized in that: the centrifugal filtration net is also to have the material that makes nonwoven, filter paper etc. have adsorptivity to make with the above non-weaving cloth of one deck.
