Description

Two sections blending high-voltage arc igniting diesel oil kitchen ranges

The utility model relates to a kind of fuel combustion device, specifically two of a kind of burning diesel oil sections blending high-tension electricity acnode fire kitchen ranges.

Most widely used gravity flow vaporation-type diesel range all is manual firing's mode at present.Need preheating 1-2 minute at the black furnace state with the cotton balls igniting, treat that food tray fires showing tremendous enthusiasm burning when prosperous, splash into the oil of food tray could be naturally evaporation constantly and the air blending of coming on every side to keep burning, starting slowly and also can over-emitting black exhaust like this, improper between elementary period as if air inlet and fuel-flow control, also can splash oily ball and emit Mars has a strong impact on surrounding environment." the diesel range igniter " of Chinese patent CN2177899Y bulletin is to adopt carbon rod energising heating igniting, the easy scaling loss of carbon rod; " the diesel oil atomization high-voltage ignition device " of Chinese patent CN2221165Y bulletin uses the high-head discharge igniting, and igniter head is in the easy carbon deposit influence of side, combustion chamber intermediate position points duration and degree of heating igniting effect.Above-mentioned two patents all are that the spray atomized diesel fuel advances kitchen range, spray into the combustion chamber through diesel oil employing level, the side of atomizing, and fuel oil is inhomogeneous in indoor meeting, and irregular phenomenon just appears in flame, be prone to the fiery heart and depart from when regulating little oil mass.What existing in addition Oil-burning range used all is one section combustion chamber, and the oil that sprays into is not easy to be fully burned, and oil loss is some more relatively.

The purpose of this utility model is for overcoming the deficiency of existing technology, provide a kind of igniting rapid, combustion stablized two sections blending high-voltage arcs igniting kitchen range.

The purpose of this utility model be achieved in that kitchen range by shaft inner cone, shaft Outer Taper, burner inner liner, go up cover and transfer the wind section to form.Between shaft inner cone and the Outer Taper and between burner inner liner and the last cover air duct is arranged.Two ducts are to be communicated with air to be pressed into from bottom to top, in the middle of the shaft inner cone is first section combustion chamber, the diesel oil atomization nozzle is housed on the inner bottom surface, in the middle of the burner inner liner is second burning zone, diesel oil is from the upwards ejection of nozzle-70 ° of mist cones at 45, with the air blending that aperture on the shaft inner cone wall enters, electrifying electrodes produces strong electric arc (electric spark) some fuel spray simultaneously.Burning is at first carried out in inner cone, and flame is hung in to be shown in the inner cone on the aperture, and because of near the of each aperture all is a little vortex, flame refluxes temperature is raise rapidly.The flame of pressure combustion and atomizing deep fat rise in second section combustion chamber flame drum, and fierce burning is carried out in the air blending that continuation and burner inner liner wall aperture are come in whole combustion chamber.Diesel oil just can be fully burned like this.The blending of cooking stove oil mass and air capacity is controlled by ratio adjusting valve, transfers wind section mouth to be provided with air door.Ignitor is provided with anti-carbon deposit protective sleeve, makes ignition arc can stablize dispensing.

Advantage of the present utility model: (1) governor motion is simple, the control easily of firepower size.(2) adopt upwards oil spray, flameholding, the ingle flame is evenly distributed.(3) adopt the two stage combustion chamber, oil plant can fully burn, and obtains high combustion heat, and flame temperature can reach 800-1100 ℃.(4) use the electrode protective jacket, prevent the electrode carbon deposit, electrode is long service time.

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

Fig. 1 and Fig. 2 show the utility model kitchen range inner body structure.Kitchen range mainly is made up of last cover (1), burner inner liner (2), inner cone (3) and Outer Taper (4).Inner cone (3) is put into Outer Taper (4) and is formed annular duct; Processing porose (9) on inner cone (3) and Outer Taper (4) the joint annulus, air can enter between burner inner liner (2) and the last cover (1) by hole (9) between inner cone (3) and the Outer Taper (4).Inner cone (3) bottom center is processed with a through hole, and the bottom outlet internal orifice is equipped with centrifugal atomizing nozzle (5), and oil inlet pipe (16) and nozzle (5) are connected.Inner cone (3) bottom surface porose (14) and oil return pipe (15) are connected, and be too much for preventing the unignited oil spout of stove fire, passes back into fuel tank.Be processed with 3-5 row air admission hole (10) on inner cone (3) wall, pore (10) successively increases from bottom to top, and the aperture is 3mm-6mm.Be added with air admission hole (8) on burner inner liner (2) wall, suitable for reading the joining of burner inner liner (2) and inner cone (3).Last cover (1) end face opening (kitchen range mouth) flame is from emerging, and end mouth and Outer Taper (4) upper end joins.A pair of anti-carbon deposit protective sleeve (12) penetrates Outer Taper (4) and inner cone (3); electrode (11) back segment has porcelain tube (13) to insert in the protective sleeve (12); the top mist awl edge that is positioned over; during two electrodes (11) energising; produce strong electric arc between top, the mist of oil of nozzle (5) ejection is lighted at once.Transfer the suitable for reading and Outer Taper (4) of wind section (6) to be connected, transfer in the wind section (6) air door (7) is housed.

Fig. 3 shows the operation principle of two sections blending high-voltage arc igniting of the utility model diesel oil kitchen range.Ratio adjusting valve (18) works to cut-off fuel oil and regulates oil pressure, oil mass, and control air valve door (7) is regulated air blast (17) in proportion and sent the air quantity of transferring wind section (6) to simultaneously.Oil pump is driven by the axle of air blast (17), and fuel oil passing ratio control valve (18) enters oil pipe (16).Excess oil return duct (15) inserts in the fuel tank (19).Electric-controlled box (20) connects the 220VAC power supply by TB output high pressure A terminals, and A terminals two lines are connected with two electrodes of igniting (11) respectively, and the B line is connected with air blast (17).Power switch (21) and button ignition switch (22) can from electric-controlled box (20) move be contained in cooking stove panel be convenient to the operation.When using cooking stove, turn on the power switch (21), air blast (17) is just started working, and control button (22) is pressed in wind and fuel oil passing ratio control valve (18) control, and stove fire just can be lighted at once.
