[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First embodiment: See also Figure 1-Figure 7 The present suspended burner comprises a base 1 and a flame distributor seat 2. A fierce fire nozzle 3 is provided at the center of the flame distributor seat 2. A fierce fire channel 31 is provided on the inner side of the fierce fire nozzle 3. The bottom of the fierce fire nozzle 3 is connected to a central gas pipe 4. The central gas pipe 4 is extended in the horizontal direction. A central air inlet 11 is provided on the base 1. The outlet end of the central air inlet 11 is aligned with the inlet end of the central gas pipe 4 in the horizontal direction and form a distance. When the gas is ejected from the outlet end of the central air inlet 11, it can drive the surrounding air into the central gas pipe 4 at the same time. Moreover, the liquid in the central gas pipe 4 will not come into contact with the outlet end of the central air inlet 11.

[0027] The outlet end of the central gas pipe 4 is located vertically below the fierce fire channel 31. A central gas cavity 41 is provided in the central gas pipe 4. The central gas cavity 41 is in the shape of a trumpet whose width increases gradually as it approaches the central air inlet 11. The shape of the central gas cavity 41 can increase the flow speed of the gas and air mixture, so that the mixed gas is discharged from the outlet end of the fierce fire nozzle 3 as soon as possible. The central gas cavity 41 can not only increase the speed of the airflow entering the fierce fire nozzle 3, but also discharge the liquid under the fierce fire nozzle 3 through the air inlet end of the central air inlet 11, thereby reducing the chance of liquid accumulation in the fierce fire nozzle 3 or the central air inlet 11 causing blockage, thereby improving the reliability of the product.

[0028] Furthermore, a fire cover is connected to the upper side of the fire distribution seat 2.

[0029] Furthermore, the fire-distributing seat 2 is provided with an outer ring fire-distributing cavity 21 and an inner ring fire-distributing cavity 22 which are concentrically arranged with each other. The outer ring fire-distributing cavity 21, the inner ring fire-distributing cavity 22 and the fierce fire nozzle 3 are distributed in sequence from the outside to the inside, so that the suspended burner can have the effect of three-ring fire operation.

[0030] Corresponding air inlet holes 23 are provided on the fire base 2 at positions corresponding to the outer ring fire chamber 21 and the inner ring fire chamber 22, and at positions corresponding to the inner ring fire chamber 22 and the fierce fire nozzle 3. The air inlet holes 23 vertically penetrate the fire base 2. When the gas is ejected outward from the outer ring fire chamber 21 and the inner ring fire chamber 22 and burns, a negative pressure can be generated, so that the gas below the fire base 2 can flow upward to the combustion position through the air inlet holes 23, thereby adding more air to the combustion, achieving the effect of upper air intake to add air, and increasing the thermal efficiency of the product. More air entering the fierce fire nozzle 3 can increase the internal pressure of the fierce fire nozzle 3, thereby increasing the heat load of the fierce fire nozzle 3 when it is working.

[0031] The base 1 is provided with an outer ring air inlet portion 12 and an inner ring air inlet portion 13 corresponding to the outer ring fire dividing cavity 21 and the inner ring fire dividing cavity 22 respectively. The air outlet ends of the outer ring air inlet portion 12 and the inner ring air inlet portion 13 are aligned with the outer ring fire dividing cavity 21 and the inner ring fire dividing cavity 22 in the horizontal direction and form a distance therebetween. The three-ring fire can be controlled independently, and the use of the suspended burner is more flexible and convenient.

[0032] Furthermore, the fire-dividing seat 2 includes an upper seat plate 24 and a lower seat plate 25, and the outer ring fire-dividing cavity 21 and the inner ring fire-dividing cavity 22 respectively include corresponding outer ring air intake channel 211 and inner ring air intake channel 221. The upper seat plate 24 and the lower seat plate 25 are fixed by riveting to form the outer ring air intake channel 211 and the inner ring air intake channel 221. The shapes of the outer ring air intake channel 211 and the inner ring air intake channel 221 are relatively complex. The processing difficulty of the outer ring air intake channel 211 and the inner ring air intake channel 221 can be simplified by riveting the upper seat plate 24 and the lower seat plate 25.

[0033] The central gas pipe 4 is integrally formed with the lower seat plate 25 or the upper seat plate 24. Since the airflow output by the central gas pipe 4 is concentrated in the fierce fire nozzle 3, the shape and structure of the central gas pipe 4 are relatively simple. Through the one-piece molding method, the overall width of the central gas pipe 4 can be relatively reduced, which is beneficial to the area of ​​the air inlet holes 23 at the peripheral position of the central gas pipe 4 on the fire seat 2 corresponding to the fire seat 2. It can be relatively increased, thereby facilitating an increase in the amount of air supply during combustion of the fierce fire nozzle 3, and further improving the combustion efficiency of the fierce fire nozzle 3 during combustion.

[0034] Furthermore, corresponding bosses 14 are provided on the base 1 below the outlet ends of the outer ring air inlet 12, inner ring air inlet 13, and central air inlet 11. Bosses 14 are integrally formed with the base 1. The vertical projection of the boss 14 corresponding to the central air inlet 11 is staggered and horizontally spaced from the vertical projection of the central air pipe 4. Bosses 14 enhance the overall structural strength of the base 1. Furthermore, when liquid drips from the central air pipe 4 onto the base 1, the bosses 14 block the accumulated water, reducing the chance of it flowing toward the outlet ends of the outer ring air inlet 12, inner ring air inlet 13, and central air inlet 11.

[0035] Furthermore, the upper ends of the outer ring air inlet portion 12, the inner ring air inlet portion 13 and the central air inlet portion 11 are respectively arranged at the lower front position corresponding to the ignition seat 2 on the base 1, and they are respectively abutted against the bottom of the ignition seat 2. The base 1 is provided with a rear support portion at the lower rear position corresponding to the ignition seat 2, and the rear support portion abuts and cooperates with the ignition seat 2. The outer ring air inlet portion 12, the inner ring air inlet portion 13 and the central air inlet portion 11 cooperate with the support portion to enable the base 1 to support the ignition seat 2.

[0036] Furthermore, a positioning recess 111 is provided at the upper end of the central air inlet portion 11, and a positioning rib 26 corresponding to the positioning recess 111 is provided on the fire distributor seat 2. The positioning rib 26 is engaged with the positioning recess 111 to improve the installation accuracy between the base 1 and the fire distributor seat 2, so that the air outlet end of the central air inlet portion 11 is easier to align with the air inlet end of the central gas pipe 4.

[0037] Furthermore, the rear support portion includes a plurality of support columns 15, each of which is provided with an upwardly protruding portion 151, and a supporting step 152 is formed between the support column 15 and the protruding portion 151. The ignition seat 2 is in contact with the supporting step 152, and a positioning socket 27 corresponding to the protruding portion 151 is provided on the ignition seat 2. The protruding portion 151 is plugged into the positioning socket 27, which can not only ensure the overall supporting effect of the base 1 on the ignition seat 2, but also further improve the installation accuracy of the base 1 and the ignition seat 2.

[0038] Furthermore, a hollow cavity 153 capable of installing an ignition needle or a thermocouple is provided on the inner side of the support column 15. The hollow cavity 153 extends from the upper end of the protrusion 151 to the lower end of the support column 15. The positioning socket 27 is provided at a position corresponding to the outer ring ignition cavity 21 and the inner ring ignition cavity 22 on the ignition seat 2. There is no need to open additional mounting holes corresponding to the ignition needle or thermocouple at other positions on the ignition seat 2, which simplifies the structure of the ignition seat 2. Workers can also first install the ignition needle or thermocouple on the hollow cavity 153 and then install and fix the base 1 and the ignition seat 2, thereby achieving the effect of improving assembly efficiency.

[0039] Second embodiment: See also Figure 8 、 Figure 9 The difference between this embodiment and the first embodiment is that the head end of the central gas supply cavity 41 of this suspension burner corresponds to the gas inlet end of the central gas inlet portion 11, and the terminal end of the central gas supply cavity 41 extends vertically below the fierce fire channel 31. The terminal end of the central gas supply cavity 41 forms a guide slope 411 at a position corresponding to the position below the fierce fire channel 31. The guide slope 411 is arranged to be inclined downward in the direction close to the central gas inlet portion 11. After entering the bottom of the fierce fire channel 31, the liquid can flow more quickly through the guide slope 411 to the central gas supply cavity 41, and then be discharged outward through the gas inlet end of the central gas supply pipe 4, which can prevent the accumulation of liquid below the fierce fire channel 31 and further reduce the chance of liquid accumulation and blockage in the fierce fire channel 31.

[0040] The remaining undescribed parts are the same as those in the first embodiment and will not be repeated here.

[0041] The above embodiments are only preferred embodiments of the present invention, and other embodiments of the present invention are also possible. Those skilled in the art may make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope set by the claims of this application.
