Summary of the invention: can not really eliminate fume pollution and exempt to clean the high shortcoming that lacks practicality, civilian property of the big cost of existing air cleaning facility volume in order to overcome existing fan lampblack absorber.The utility model provides a kind of oil smoke fan lampblack absorber that removes, should remove oil smoke fan lampblack absorber airborne oil smoke of pollution abatement and various harmful substance almost completely up hill and dale, thoroughly exempt to clean, and waste oil can reclaim, overall cost is low, volume is little, efficient is high, can popularize civilianly, can solve the problem of civilian and restaurant's fume pollution harm admirably, other air cleanings detoxifcation humidifications add problem such as perfume (or spice) and also all can solve in the lump.

The technical scheme that its technical problem that solves the utility model adopts is:

The blade shaft pipe box of centrifugal blower is put silk screen sponge cover, and preferably change double-deck hollow sleeve axle sleeve into, make the front and rear water inlet pipe plug together appropriate with it and rinse water is flow to into mesh-structured fan blade axle sleeve position, utilize the high speed rotating of fan blade to make axle center water liquid fully be refined into centrifugal the flying out of the great fine drop of quantity, produce and to advance flue gas with institute to clash into stirring and washing first mixed, fly to blade and mixed subsequently jointly, produce for the second time and clean by the stirring of fan blade bump.And the suitable position of blade establish the frivolous filter screen filter cloth of single or multiple lift (forward and backward facade and in outer rim etc. all can), carry out diafiltration subsequently and the centrifugal gas flow drop that throws away, constitutes more powerful for the third time effectively thorough cleaning link.Particularly this type of lightweight filter screen filter cloth is made specially the continuous folding corresponding and bent lenticular structure with fan blade, so just can the utmost point easily plug-in card be installed between the former fan blade, with maximum filtering area, the loss of minimum running resistance wind-force, optimal adhesion side angle, preferably centrifugation self-cleaning mode is efficiently taken off smoke evacuation dirt greasy dirt.After this still bump pulverizing repeatedly in machine lumen road of air-flow and drop continues continuous wash to self and blower fan inner chamber parts.Airduct inwall and facade also can be established same filter screen backing member and aqueduct carries out further diafiltration, so overall cleaning performance is excellent.Used current can directly draw from running water, give and put the inertia reflux tank or the various pump formula circulatory system, and can add liquid detergent, essence and extraordinary detoxicating liquid or the like easily and reach ventilation, humidification, add perfume (or spice), beneficial effect such as detoxifcation.Also further water-oil separating, waste oil reclaim.

The beneficial effects of the utility model are only to pass through the minor alteration and the annex of a centrifugal fan, just constitute a thoroughly efficient ventilation cleaning equipment that cleans the scrubbing dedusting automatically, not only can almost use up oil smoke in the deacration, and can lower the temperature to the air automatic humidification, body forever exempts to clean, waste oil is recyclable, also can reach special-effects such as air detoxifcation perfuming by additive, becomes effective conventional equipment of reply terrorist poison gas harm.Volume is little, cost is low, efficient is high, and reliable durable is simple in structure.Because can produce air clean and cooling immediately, the restaurant realizes in line on the spot with saving a large amount of ventilation ducts and energy consumption, and can permanent releasing oil smoke harm.

Description of drawings: the utility model is further specified below in conjunction with drawings and Examples.

Fig. 1 is kind of a centrifugal blower lampblack absorber example structure sketch, schemes last 1 motor, 2 motor shafts, the double-deck concentric locking collar tubular axis of 3 fan blades, 4 silk screen sponge covers (tubular taper etc.), 5 centrifugation blades, 6 filter screen filter clothes, 7 former long-pending oily outlets, 8 miniature immersible pumps, 9 cleaning fluids, 10 water tanks, 11 water inlet pipes, 12 drainpipes, 13 water pumping pipes, the double-deck concentric locking collar tubular axis of 14 fan blades apopore, 15 discharge pipes, 16 rivets.

Fig. 2 is double-deck concentric locking collar tubular axis embodiment enlarged drawing.It is similar and omit and draw that other Two Piece Set closes frame mode.

Fig. 3 is kind of a centrifugation blade and many warpages filter structure assembling legend, and the most advanced and sophisticated corresponding blade space that inserts of the filter screen of warpage continuously not only makes self fixing mounting or dismounting utmost point just, also make flue gas with it contact area heighten the diafiltration better effects if.As for from the place ahead air inlet nanubrium drip washing mode (figure is slightly), often must clean because of managing the outer greasy dirt that is subject to, not preferred plan.Air outlet is established with reversal valve, and purification promptly capable of reversing disappears and washes humidification and add fragrant room air, also can save oneself by smoke abatement when fire, (figure slightly) also with practical value.

Fig. 4 cuts open figure for the minimum gravity flow mode office of cost, spacious water tank 10 places oil smoke cabinet top, connect discharge pipe, fan blade water inlet pipe, water tank water storage respectively with a three-way pipe, make it float on the water surface with a foam floating block 17, air draft after the start, exhausting form low pressure, make water tank water from entering the fan blade axocoel communicating pipe, automatic cut out (can establish flow switch in addition) then when shutdown or weak wind.Drainpipe also can directly feed sewer pipe (figure slightly).

Fig. 5 is kind of a centrifugal aerofoil fan embodiment side view.Fig. 6 is that it is overlooked and partly cuts open figure.Scheme last 18 blast pipes, 19 drip rings, 20 water pouring mouths, 21 magnetic valves, 22 drainpipes, 23 oil exit pipes, 24 communicating pipes, 25 bearings.

The specific embodiment: in Fig. 1 embodiment, water tank is that water inlet pipe and water outlet pipe is still used former lampblack absorber outage, this case is the simple modifications scheme of former lampblack absorber in fact, better scheme is that water tank is fixed with two side bayonet slots and constitutes one (shown in the dotted line) at the casing bottom surface, moves stretching behind the water inlet pipe and water outlet pipe and removes crooked waste from.

Fig. 2 is one of concentric locking collar tubular axis compound mode, preferably makes with light strong rush-resisting material (alloy aluminum etc.), smart casting turning all can, two-piece type is combined into one in the tight fit mode, guarantees firmly and with one heart.

Fig. 3 mode is the simplest honest and clean, but its pipeline must be the shortest and more slightly to reduce windage, and the envelope shelves of bottom must be tight, could constitute enough pressure reduction and effective.

The warpage formula filter screen of Fig. 4 obviously is to be made as suitablely with the stainless steel fine-structure mesh, gets final product roll forming with one group of involutory gear.

Fig. 5,6 embodiment also are the optimised form of present restaurant with the elimination oil smoke, can be in line because of producing that clean air of lowering the temperature is several, reduce expenses so can significantly shorten pipeline, use two water tanks can strengthen moisture storage capacity and make the appearance looks elegant balance, but the main water box that contains the intake-outlet water pipe must be positioned at the side that current inertia rises, like this when start water inlet drip washing to managing prodelta clay water when reaching q.s, rapidly the fan blade that rotates just can contact and drive its inertia rising, under protecting, drip ring (semi-ring gets final product) retaining enters water tank from the water pouring mouth, fluid is then automatically floating on it, accumulate and can fluid be taken away, reach fluid and reclaim by flowline on the floating block 19 of the floating water surface.That water tank is preferably is transparent (one side at least) and lid is arranged, and is convenient to observe with supplementing water liquid, covers completely closely, and it is fair just can to go into the gas supercharging in entry, makes entry (liquid) and does not go into gas.But oral siphon magnetic valve and switch serial or parallel connection get final product one or control its use respectively in the motor lead.

Certainly, only with axle center drip washing or only join the warpage filter screen with centrifugation blade, the former effect can reach more than 70%, latter Ke Da 50%, and the two is in conjunction with effect optimum then.Add big yield, even the superposition use, all can reach almost 100% effect.

Obviously, the leakproof of blower fan inner chamber is antirust to be strictly to solve, and electroplates and make lacquer all to reach firmly permanent practical function.
