Specific embodiment

It is practical new to this below in conjunction with attached drawing to keep the purpose of this utility model, technical solution and advantage clearer Type embodiment is further described.

Fig. 1 and Fig. 2 are please referred to, the embodiments of the present invention disclose a kind of based on the effective burning of heated by natural gas radiation Mouth, including a burner shell 1 and a combustion barrel 2, the burner shell 1 includes an arrival end 101 and an outlet end 102, described Arrival end 101 by the fixed sealing plate 3 of bolt, close to 1 outer wall of the burner shell of the arrival end 101 be equipped with one into Air port 4, the outlet end 102 are fixedly installed with the combustion barrel 2 by several support columns 5, and the support column 5 is angularly set In 2 outer wall of combustion barrel, the support column 5 can with 2 integrated setting of the burner shell 1 and the combustion barrel, it is described 1 outlet end of burner shell threaded connection, one protection shell 15, the outer diameter for protecting shell 15 and the burner shell 1 Outer diameter is identical, therefore the appearance globality after the installation of the two screw thread is preferable, 15 end of protection shell and the combustion A fixed secondary air ring 6 between 2 outer wall of cylinder is burnt, several vents 2, the combustion barrel 2 are angularly equipped on the secondary air ring 6 One end is extended to receive the air entered from the air inlet 4 in the burner shell 1, and the other end passes through the protection shell It is extended to after 15 outside the protection shell 15, thus the protection shell 15 can carry out exterior protection to the combustion barrel 2, described A fixed air-distributing disc 7 in 2 radial section of combustion barrel, the air-distributing disc 7 are successively arranged first air holes of circle 701, one except interior The second air holes 702 and a circle third air holes 703 are enclosed, first air holes 701 is straight hole, second air holes 702 and third wind Hole 703 is the inclined inclined hole of same direction, and the shape of second air holes 702 and third air holes 703 is oblique circular cylinder shape, thus empty Gas after first air holes 701, the second air holes 702 and third air holes 703 gas rotating mix speed faster, flowing Apart from longer.

Several air holes 8 are uniformly provided on 2 barrel of combustion barrel, 2 side wall of the combustion barrel outside the air holes 8 On be slidably installed an adjusting ring 9, the adjusting ring 9 is equipped with and the one-to-one circular hole 901 of the air holes 8, the circular hole 901 Diameter is identical as 8 diameter of air holes, the adjusting ring 9 can the combustion barrel 2 sliding or fixed relatively, and then it is adjustable described Air holes 8 and the circular hole 901 it is interlaced formed aperture size, thus adjust from the mixed gas in the combustion barrel 2 into Enter to the scale of construction in the protection shell 15, in the present embodiment, 2 outer wall of combustion barrel is in axial direction equipped at least two Item limits road, and several limiting slots 12 are equally spacedly equipped in each limit road, and 9 inner wall of adjusting ring is equipped with and the limit The one-to-one flexible fastening piece 13 in position road, the flexible fastening piece 13 can be moved along the limit road, and the elasticity is solid Determining part 13 can fix with any cooperation of limiting slot 12, and the flexible fastening piece 13 includes at least two positioned at same axis side Upward blind hole slot 131, each blind hole slot 131 is interior to be equipped with a limit hoodle 132 and a pressure spring 133, the limit hoodle 132 diameter is open greater than the blind hole slot 131, and the pressure spring 133 pushes the limit hoodle 132 to the blind hole slot 131 Opening and form a protrusion, the shape of the shape of the limiting slot 12 and protrusion matches, in this way when the limiting slot 12 and described Protrusion be combined with each other, and the adjusting ring 9 can be fixed, while push the adjusting ring 9, can compress the limit Steel ball 132 is retracted in the blind hole slot 131, until being moved in the corresponding limiting slot 12 in target position, the limit steel ball 132 The blind hole slot 131 is stretched out again enters the fixation realized in limiting slot 12 and adjust ring.

Distance between adjacent two limiting slot 12 is equal with the limit diameter of hoodle 132, the limit bullet The diameter of pearl 132 is less than the diameter of the air holes 8, for example, when the diameter of the limit hoodle 132 is 8 diameter of air holes A quarter, in this way when air holes 8 and the circular hole 901 are completely coincident, the aperture on the combustion barrel 2 is maximum at this time, when pushing away Move the adjusting ring 9 limit moved forward in road once to next limiting slot 12 when, air holes 8 and the mutually friendship of circular hole 9 at this time The sectional area of mistake, aperture becomes smaller, and so on, push the adjustings ring 9 forward movement twice and three times when, the sectional area of aperture Also further can constantly it become smaller, when pushing the adjusting ring 9 to move forward 4 times, the air holes 8 and the circular hole 901 are just It can be staggered completely, any aperture is just not present in 2 side wall of combustion barrel, therefore the movement for adjusting ring 9 in limit road Four gears that aperture size can be achieved are adjusted.

One gas-jet tube 10 is fixed after sequentially passing through at 7 center of air-distributing disc and at 3 center of the sealing plate, the coal Gas blowout pipe 10 is located at 3 lateral ends of sealing plate equipped with a fuel gas inlet 1001, and the other end is equipped with a spray head 1002, the combustion Gas import 1001 connect gas pipeline, natural gas can directly from the fuel gas inlet 1001 enter and from spray head 1002 spray and Air mixing in the combustion barrel 2.

It is respectively mounted switch hand valve, electronic stop valve and balanced valve on air pipeline and gas pipeline, switch hand valve can be It is used when burner failure or repair and replacement valve, electronic stop valve can be electrically connected controller, and be controlled by computer Controller controls the closing and opening of electronic stop valve, and balanced valve can be used to control the air and gas flow of each burner, So that the air and gas flow of each burner reach balance.

10 upper and lower of gas-jet tube is equipped with two ignitors 11 for lighting a fire for the spray head 1002 respectively, often One ignitor 11 is lighted a fire after one end passes through the air-distributing disc 7 and is fixed, and the other end is located on the outside of sealing plate 3 outer for connecting Power supply is connect, the electric spark that the ignitor 11 generates after being powered can light mixed air and combustion gas.

Further, a peep hole is additionally provided on the sealing plate, operator can be directly by peep hole to observe The combustion case in burner shell 1 is stated, and then adjusts the proportion of air, combustion gas, guarantee achievees the effect that burning.

Specific embodiment described in the utility model is only to give an example to the spirit of the present invention.This is practical Novel person of ordinary skill in the field can make various modifications or additions to the described embodiments or adopt It is substituted with similar mode, but without departing from the spirit of the present application or surmounts model defined in the appended claims It encloses.
