Description

Whole hot air energy saving burning nozzle

The utility model relates to a kind of full hot blast Energy saving burning nozzle, belongs to industrial oil oven combustion tool.

The present invention is to be a kind of improvement of 92217374.5 a kind of energy-conservation shouting mouth to the patent No..The advantage of the energy-conservation shouting mouth of former L type is: for the low-temp low-pressure igniting easily, adopt insulation in the mouth, make burning heavy oil, residual oil be difficult for stopping up noncoking, the adjusting ratio is big, the even advantage of temperature in the stove, but also have certain defective, can not use high-temperature hot-air, make when little oil mass flameholding very high to air pressure and steam pressure conditional request, bad control during operation, little oil mass ignition difficulties of while, and also maintenance is very inconvenient.

The purpose of this utility model provides the energy-conservation shouting mouth of a kind of newly-designed full hot blast, makes it supply under 600 ℃ of hot blast state status operate as normal and noncoking; It is very convenient to keep in repair.Little oil mass burning is very stable.

This full hot blast Energy saving burning nozzle is by housing 1, air nozzle 2, steam jet 3, oil nozzle 4, spinning disk 5, trundle 6 is transferred steam casing 7, piston ring 8, air regulating sleeve 9, oil pipe 10, guider screw 11, roll sleeve 12, collet 13, handlebar 14, rotary axle box 16, bracket 17, valve seat 18, spool 19, ratio adjusting rod 20, handwheel 22, seal receptacle 24, power transmission shaft 26, spring 28, screw 29 constitutes, and its concrete structure is:

An end that is provided with fuel feed hole on bracket 17 valve seat 18 that is being spirally connected, an accent steam casing 7 that has piston ring groove on external cylindrical surface in the loose joint of other end screw thread, overlaps 7 affixed 6 of trundles with this regulating the qi flowing in the channels and is placed in the microscler pin-and-hole of air nozzle 2.

An end of described valve seat 18 affixed one with the affixed oil pipe 10 that is one of oil nozzle 4 screw threads, the valve seat other end is provided with seal receptacle 24, is provided with spool 19 in both cavitys, and is provided with handwheel 22 through the afterbody with the power transmission shaft 26 of spool 19 interlocking.

With the upper end of air nozzle 2 affixed all-in-one-piece air regulating sleeves 9, rabbet a rotary axle box 16, be provided with the collet affixed 13 in the outside at these rotary axle box 6 interlocking positions with it, on rotary axle box 16, be provided with control stick 14 simultaneously.

On the cone wall of housing 1 air nozzle one end, have several oblique through holes 30.

According to the full hot blast Energy saving burning nozzle of LR type of above conceptual design, to compare with L type burner, its advantage is: can be for operate as normal under the situation of 600 ℃ of hot blasts, noncoking.

Very stable ignition is rapid not needing the generally speaking little oil mass that air pressure and steam pressure carry out special adjustment burnt; Simultaneously also make maintenance and repair very convenient.

Accompanying drawing 1 is full hot blast Energy saving burning nozzle structural representation.

Each part member title is as follows among the figure:

1-housing 2-air nozzle 3-steam jet 4-oil nozzle 5-spinning disk 6-trundle 7-regulating the qi flowing in the channels cover 8-piston ring 9-air regulating sleeve 10-oil pipe 11-guider screw 12-roll sleeve 13-collet 14-handlebar 16-rotary axle box 17-bracket 18-valve seat 19-spool 20-ratio adjusting rod 21-nut 22-handwheel 23-ratio dog screw 24-sealing shroud 25-sealing ring 26-power transmission shaft 27-asbestos seal filler 28-spring 29-screw.

This burner is that L type burner is further improved and a kind of novel burner of formation.It is characterized in that having on bracket 17 end of the fuel feed hole valve seat 18 that is spirally connected, the regulating the qi flowing in the channels cover 7 that the other end is spirally connected and has piston ring groove on external cylindrical surface overlaps 7 affixed trundles with this regulating the qi flowing in the channels and then is placed in the microscler pin-and-hole of air nozzle 2.An end of valve seat 18 affixed one with the affixed all-in-one-piece oil pipe 10 of oil nozzle 4 screw threads, the valve seat other end is provided with seal receptacle 24, is provided with spool 19 in both cavitys, and is provided with handwheel 22 through the afterbody with the power transmission shaft 26 of spool 19 interlocking; With the upper end of air nozzle 2 affixed all-in-one-piece air regulating sleeves 9, rabbet a rotary axle box 16, its outside is provided with the collet affixed with it 13, is provided with control stick 14 simultaneously on rotary axle box 16.On the cone wall of housing 1 air nozzle one end, have several oblique through holes.

Now its operation principle is expressed as follows:

The operation principle of this burner is the same with L type Energy saving burning nozzle, when this pouring mouth its operation principle under the not high situation of steam pressure identical with R type burner, oil by low-pressure air carry out three times the atomizing.When this burner uses under the vapour pressure ratio condition with higher, its operation principle is identical with CW type exterior mixing high pressure burner operation principle, it be utilize the high speed rotation steam flow that sprays in the steam passage between vapour shower nozzle and the oil nozzle to fuel oil impact with rubbing action with oil atomization.

Under the combustion case of little oil mass, L type burner in the past is in order to effectively utilize the atomizing energy of blast and vapour pressure, what adopted all is to change spray volume by the projected area that changes spout, but the shortcoming that it has is: weakened its revolving force greatly under the situation of little air quantity and little vapour amount, make when little oil mass is burnt and be difficult to form recirculating zone (flame-stabilizing area) and very difficult the stablizing of burning, ignition difficulties.Make it wind in a small amount ejection in the inclined hole and form eddy flow and have several inclined holes on the cone wall of housing air nozzle one end of this LR type Energy saving burning nozzle, form the recirculating zone so effectively when little oil mass burning, make it flameholding, igniting rapidly.

At oil pipe with outside adopt totally-enclosed double thermal insulation, make the steam passage wall that cold wind can not blow to the inside and protected steam not to be condensed into oil thermal insulating effectively on the structure of this burner, make hot blast can not blow the people, protected the oily noncoking in the oil pipe owing to be provided with collet.In addition, all sealings of this burner all are to adopt temperature resistant encapsulation, thus it can be under the situation of high temperature wind operate as normal.

This burner is because the valve seat that is fixed together with oil pipe and oil nozzle that is spirally connected on bracket, so when maintenance, as long as with spanner valve seat being back-outed just can extract oil nozzle, oil pipe together out very easily lead to slag, cleaning etc. to oil duct, steam passage, has solved former burner and easily blocked up difficulty and the maintenance difficult shortcoming such as lead to.

This burner greatly improves manufacturing process because of being provided with the accent steam casing 7 that has piston ring groove on the external cylindrical surface, and is simple in structure, and manufacturing cost reduces, and because of resistant to elevated temperatures piston ring packing is housed, has improved service life effectively, has reduced maintenance frequency.

It is simple to operate to use this burner to have, easy to maintenance, can be operate as normal under 600 ℃ the condition in the air feed temperature, atomization quality is good, little oil mass flameholding, flame is even, regulates than big, igniting rapidly, to heavy oil, not condensation of residual oil, noncoking, adaptability is strong, extensively be adapted to some temperature requirements such as heat-treatment furnace, Beijing enamel kiln and change greatly the frequent middle low-temperature industrial stove of lighting a fire.
