Abstract

The utility model relates to a cooking stove, in particular to an oil-gas dual-purpose burner with a bucket evaporator and a reinforced pipe. The burner is composed of a shell, an oil pipe at the center of an inner cavity of the shell, an ignition bowl at the upper part, and an air inlet pipe which is positioned at the lower side of the shell and communicated with the inner cavity of the shell, wherein a section of the oil pipe positioned in the ignition bowl is connected with a spray head, a flame stabilizer is connected on the shell, an air inlet pipe connected with the spray head is arranged outside the oil pipe, and oil spray holes and air spray holes which are respectively communicated with the oil pipe and the air inlet pipe are crossly and uniformly distributed on the spray head.

Description

Bucket oil-gas burner

The utility model relates to a kind of cooking kitchen range, specifically a kind of oil, gas dual burner that has bucket type evaporimeter and enhanced tube.

Existing oil, the dual-purpose kitchen range of gas are a kind of with carburation by evaporation oil burner and combustion gas mostly---the structure that air part premix burner is combined, the defective of this structure is that air inlet pipe is not or not the center of housing inner chamber, thereby,, air inlet make the flare in the whole fire bowel inhomogeneous owing to departing from the center when combustion gas during in the fire bowel internal combustion.

The purpose of this utility model is to design a kind of can being used alternatingly by oil gas, can use simultaneously again, and the even and strong burner of burning fire power.

Its main technical schemes is this burner by the fire bowel (2) on the oil pipe (15) of housing (11) and lumen centers thereof and top and is positioned at housing (11) downside, and the blast pipe (19) that is communicated with housing (11) inner chamber constitutes, be positioned at one section last shower nozzle (8) that connects of fire bowel (2) at oil pipe (15), on housing (11), connect steady firearm (1), the air inlet pipe that is connected with shower nozzle (8) is housed in the outside of oil pipe (15), go up uniform nozzle opening (9) that is communicated with oil pipe (15) and air inlet pipe respectively of intersection and fumarole (18) at shower nozzle (8), between oil pipe (15) and nozzle opening (9), cannelure (7) can be set; The enhanced tube of uniform at least two tube wall belt holes (3) on the bottom surface of fire bowel (2), the bottom of enhanced tube (3) is communicated with the inner chamber of housing (11), the evaporimeter (4) that on shower nozzle (8), connects spill, gas-tpe fitting in the air inlet pipe (12) is connected with shower nozzle (8), one end of reducer tee (13) is connected with joint (12), the other end is by pipe plug (16) sealing, and the centre is connected with tracheae (17).

The utility model has the advantages that owing to change the mode of original more monolateral oil-feed gas into center oil-feed gas mode, and set up evaporimeter and enhanced tube, cause fuel behind evaporation, vaporization, premix, burn more fully, even, strong, perfect.

Fig. 1 is a structure chart of the present utility model.

Further describe embodiment of the present utility model below in conjunction with accompanying drawing.

Air door (14) is contained on the blast pipe (19) of housing (11) bottom, the center of housing is provided with oil pipe (15) and reaches by pipe plug (16), reducer tee (13), the air inlet pipe that gas-tpe fitting (12) constitutes, oil pipe stretches out housing (11) bottom, a shower nozzle (8) is adorned at top at oil pipe (15) and gas-tpe fitting (12), and pass the bottom of fire bowel (2), at fire bowel bottom uniform five enhanced tubes (3), fire bowel (2) is contained in the top of housing, adorn an end socket (6) at the top of shower nozzle (8), adorn an evaporimeter (4) at its top, and with screw (5) tightening, steady firearm (1) be contained in housing (11) and fire bowel (2) above, tracheae (17) passes housing (11) and is connected with reducer tee (13), when using fuel gas buring, the lid (10) of will getting angry is contained in the fire bowel (2) and the top of five enhanced tubes (3).

When using oil inflame separately, in fire bowel, put into earlier a small amount of fuel oil or alcohol, again with the fire rod that speckles with kerosene or diesel oil, fuel oil in the fire bowel is lighted the about 15-30 of preheating second, open delivery valve, making fuel oil flow to nozzle opening through oil pipe to the cannelure (7) on shower nozzle top enters in the fire bowel, because of fire bowel preheating, the very fast carburation by evaporation burning of fuel oil, then start air blast, strengthen air quantity, then air enters in the cavity between housing and the fire bowel by air door, passes through from the aperture of fire bowel and enhanced tube at last, enter in the combustion zone, because but fuel oil vapour evaporates on the limit, the limit burning, in the process of Bian Shangsheng, contact with air with evaporimeter under the condition of high temperature, thereby strengthened clean-burning condition from fire bowel top.

When using fuel gas buring separately, start air blast, close air door, with ignition or the igniting of other incendiary source, open steam supply valve, make combustion gas through tracheae, reducer tee, gas-tpe fitting is to the fumarole of shower nozzle, spray into fire bowel and get angry combustion gas---the air pre-mixing chamber that forms between the lid, after air from fire bowel and enhanced tube aperture mixes, from getting angry lid spout all around, enter the combustion zone burning of ignition upper part of the cover with certain flow velocity, then strengthen air quantity, an amount of air is mixed, after flammable mixture enters the combustion zone, because replenishing of twice air and active combustion immediately with combustible gas.

When using oil with combustion gas mixed combustion simultaneously, treat that combustion gas is lighted after, first preheating 10-20 opens fuel tap after second, strengthens air quantity, the quantity delivered of suitably regulating fuel oil and combustion gas is so that after-flame degree and intensity of fire are all good.

Claims

1, a kind of oil burner, by the fire bowel (2) on the oil pipe (15) of housing (11) and lumen centers thereof and top and be positioned at housing (11) downside, and the blast pipe (19) that is communicated with housing (11) inner chamber constitutes, be positioned at one section last shower nozzle (8) that connects of fire bowel (2) at oil pipe (15), on housing (11), connect steady firearm (1), it is characterized in that the air inlet pipe that is connected with shower nozzle (8) being housed, go up uniform nozzle opening (9) that is communicated with oil pipe (15) and air inlet pipe respectively of intersection and fumarole (18) at shower nozzle (8) in the outside of oil pipe (15).
