Abstract

The utility model relates to a fume purifying box. A main body is a purifying box, two ends of the fume purifying box are in a conical shape, and the middle part of the fume purifying box is in a cylindrical shape. A right end air inlet (6) is connected with a fume collecting cover, and a left end air outlet (15) is connected with an exhaust pipe. The inner structure of the purifying box is divided into a front and a back chambers by a front, a middle and a back brackets (9), and two impellers (8) having three vanes are arranged between the front and the middle brackets. The purifying box is connected and fixed by a bearing (10) and a rotating shaft (11) and driven by a left side motor (12) of the middle bracket, and the purifying box is taken as a stirring and centrifugal movement mechanism. The back bracket is provided with exhaust fans (13, 14) used for exhausting purified thermal gas. The bottom of the box is attached with a device used for conveying purifying agent and reclaiming and circulating mixed liquid purified in the box.

Description

The fume purifying case

The utility model relates to the kitchen oil fume purifying technology.

The method of domestic households kitchen fume processing at present mainly contains three kinds: 1, exhaust fan mist extractor; 2, smoke exhaust ventilator mist extractor; 3, build Smoke-less range table, the exhaust fan mist extractor.The catering trade kitchen mainly utilizes high-power exhaust fan mist extractor.More than handle the method for oil smoke, common shortcoming is to cause air pollution, and in lampblack-pumped process, oil smoke stain again take out that (row) gas fan is gone up, on the smoke exhaust ventilator, window is inside and outside and wall on, the contaminated environment of accumulating over a long period is difficult to cleaning.

The purpose of this design provides a kind of fume purifying case that reduces air and environmental pollution.

Technical solutions of the utility model are, design a kind of oil fume-purifying box body, take out (row) device of air in, the case outer by case, form low-voltage space in case, and kitchen fume flows in the case by the collecting hood that is connected the case mouth automatically; Spray a kind of fume purifying agent simultaneously in case, through motion stirring, centrifugal action in the case, oil smoke is cleaned agent and absorbs, and becomes at the bottom of the liquid flow tank, and outside the outlet, remaining hot gas is discharged the kitchen by taking out (row) gas fan side by side.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1, fume purifying case are formed schematic diagram.

One of Fig. 2, fume purifying case scheme cutaway view.

Two cutaway views of Fig. 3, fume purifying case scheme.

Fig. 4, fume purifying agent transport conveyor constructions schematic diagram.

Referring to Fig. 1, the fume purifying case is made up of three parts: 1, cooking fume-collecting cover (1) and elbow (2), and 2, purifying box (3), 3, discharge duct (4) and exhaust fan (5), integral installation is above the kitchen range top; Collecting hood (1) is funnel-form, makes double-decker by stainless steel and engineering plastics, purifying box (3) middle part cylindrical shape, it is conical that two ends are, lid is arranged at top, and right-hand member is connected with collecting hood (1) by elbow (2), and left end connects discharge duct (4) and exhaust fan (5).

Referring to Fig. 2, one of fume purifying case scheme, internal structure is: the case right-hand member is air inlet (6), left end is gas outlet (15); Before, during and after in the case grid type support (9) is housed, and is connected and fixed with tank wall; Case after-poppet (9) dress motor (14) and impeller (13) constitute exhaust fan; Middle bracket (9) dress motor (12), its axle is connected and fixed with rotating shaft (11) left end, rotating shaft (11) right-hand member is fixed in the bearing (10) of fore-stock (9), two triplicate blade impellers (8) are contained in respectively in the rotating shaft (11) on middle part, front carriage (9) right side, drive by motor (12), as stirring, centrifugal mechanism; Two cleanser nozzles (7) are adorned in the inwall both sides before the case, and bottom porose (22) is as the liquid outlet behind the fume purifying behind the case.Fume purifying agent conveying device has been set up in the purifying box bottom, is represented by dotted lines (seeing Fig. 4 for details), and circuit control button (19) is installed in the purifying box side.

Referring to Fig. 3, fume purifying case scheme two big than one of scheme power is suitable for catering trade.Its architectural feature is: casing is for circular partially, and two ends are inclined to one side taper shape, are equipped with two in the case and rafting actuation mechanism, with case axis symmetry; Before, during and after in the case grid type support (9) is housed, after-poppet is equipped with two exhaust fans (13,14), on the bearing of middle part, front carriage two rotating shafts (11) are housed, the left end of two rotating shafts (11) directly is connected respectively with the axle of after-poppet two motors (14), and is fixing with nut (23); Four triplicate blade impellers are contained in respectively in the rotating shaft (11) on middle part, front carriage (9) right side.Two rafting actuation mechanism is driven by two motors (14) of after-poppet (9) respectively, and remainder is identical with one of scheme.

Referring to Fig. 4, fume purifying agent conveying device is fixed on the purifying box bottom by a vinyl disc (17) with screw (30); Cleanser jar (20) is contained in the left part in the vinyl disc (17), and micro pump (18) is contained in upper right quarter in the dish, dish right lower quadrant (29) permanent circuit element (capacitor, speed governing with inductor etc.); Cleanser jar mouth (27) up so that add cleanser, a right hole, middle part (25) is connected with micro pump (20) water inlet above jar, left hole (26) are communicated with pipeline (21), the waste liquid of a jar bottom outlet (28) after by the beneath drainage purification of vinyl disc (17).Micro pump (20) delivery port is installed three joints (24) and is communicated with twin flue (16); Filter mantle (32) is housed in the case bottom outlet lid (31) and communicates with lid bottom outlet (33), bottom outlet (28,33) is sealed by screw lid.

2, the preparation of cleanser.Cleanser is a liquid, form source analysis research according to oil smoke, it comprises the flue gas (obviously containing many harmful substances in them) that fossil fuel such as oil liquefied gas, kerosene, diesel oil, coal gas, coal form, oil gas part during by the cooking fried frying in shallow oil fry the animal and plant fat gas that produces, also have burnt flue gas and the steam of sticking with paste.Therefore the preparation of cleanser selects for use kinds of surface activating agent and relevant auxiliary agent to form, and produces special-purpose safe, nontoxic, no corrosive liquid cleanser.
