Description

Technical Field

[0001] The utility model belongs to the technical field of burners, and in particular relates to a post-premix surface burner. Background Art

[0002] Burner is a general term for a device that sprays fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application areas. They are mostly made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium.

[0003] The gas and air are premixed into a uniform mixture. This combustible mixture is called premixed gas. The process of ignition and combustion of the premixed gas in the burner is called premixed combustion. The existing post-premixed surface burner cannot adjust the amount of gas supply during use. When the gas supply is too large, it will lead to incomplete combustion of the mixed gas, resulting in waste. When the gas supply is small, it may not meet the combustion requirements, which is inconvenient for people to use. Utility Model Content

[0007] As a further optimization scheme of the utility model, the first rotating mechanism includes a rotating rod rotatably connected to one side of the sealing plate, a plurality of rotating blades installed at one end of the rotating rod, and a mixing mechanism installed between the plurality of rotating blades and the sealing plate.

[0008] As a further optimization solution of the present invention, the mixing mechanism includes a plurality of mixing components, and the mixing components include a plurality of mixing rods installed outside the rotating rod.

[0009] As a further optimization scheme of the utility model, the adjustment mechanism includes a baffle rotatably connected to the inside of the mixing tube and affixed to one side of the sealing plate, a plurality of second air holes opened on the baffle and corresponding to the plurality of first air holes, and a second rotating mechanism installed on one side of the baffle to drive the baffle to rotate.

[0010] As a further optimization scheme of the utility model, the second rotating mechanism includes a connecting rod fixedly connected to one side of the sealing plate, a rotating rod rotatably connected to the inside of the mixing tube, a first bevel gear installed at one end of the rotating rod, and a second bevel gear installed at one end of the connecting rod and meshing with the first bevel gear.

[0011] As a further optimization solution of the utility model, one end of the rotating rod extends to the outside of the mixing tube and is equipped with a rotating handle.

[0012] The beneficial effect of the utility model is that the gas supply volume can be adjusted according to specific usage conditions during use, thereby reducing the problem of insufficient gas supply or excessive gas supply, thereby making it more convenient for people to use.

DETAILED DESCRIPTION

[0018] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1 - Figure 4As shown, a post-premix surface burner comprises a burner body 1, a mixing tube 2 arranged at one side of the burner body 1, and a flame-spraying tube 4 installed at one end of the mixing tube 2 through a connecting flange 3, a sealing plate 6 is installed inside the mixing tube 2, a plurality of first vent holes 11 are opened on the sealing plate 6, a first rotating mechanism is installed on one side of the sealing plate 6 close to the burner body 1, and an adjusting mechanism for adjusting the ventilation size of the plurality of first vent holes 11 is installed on the other side of the sealing plate 6, the adjusting mechanism comprises a rotating mechanism connected inside the mixing tube 2 and in contact with one side of the sealing plate 6 A baffle 5, a plurality of second air holes 14 opened on the baffle 5 and corresponding to the plurality of first air holes 11, and a second rotating mechanism installed on one side of the baffle 5 to drive the baffle 5 to rotate, the second rotating mechanism includes a connecting rod 15 fixedly connected to one side of the sealing plate 6, a rotating rod 10 rotatably connected to the inside of the mixing tube 2, a first bevel gear 12 installed at one end of the rotating rod 10, and a second bevel gear 13 installed at one end of the connecting rod 15 and meshing with the first bevel gear 12, one end of the rotating rod 10 extends to the outside of the mixing tube 2 and is equipped with a rotating handle 16.

[0021] It should be noted that when the amount of air supply needs to be adjusted during use of this type of post-premix surface burner, the rotating handle 16 is turned, and the rotating rod 10 will drive the first bevel gear 12 to rotate. With the cooperation of the first bevel gear 12 and the second bevel gear 13, the connecting rod 15 will be driven to rotate, and the baffle 5 will rotate under the drive of the connecting rod 15. Under the action of the baffle 5, the multiple second air holes 14 will be displaced, so that the multiple second air holes 14 and the multiple first air holes 11 are in a misaligned state, so that the baffle 5 will block the multiple first air holes 11, thereby reducing the size of the ventilation openings of the multiple first air holes 11, and then reducing the amount of air supply. When the positions of the multiple first air holes 11 correspond to the multiple second air holes 14, the air supply is at its maximum.

[0022] Example 2

[0023] like Figure 1 - Figure 4 As shown, a post-premix surface burner, the first rotating mechanism includes a rotating rod 7 rotatably connected to one side of a sealing plate 6, a plurality of rotating blades 9 installed at one end of the rotating rod 7, and a mixing mechanism installed between the plurality of rotating blades 9 and the sealing plate 6, the mixing mechanism includes a plurality of mixing components, and the mixing components include a plurality of mixing rods 8 installed outside the rotating rod 7.

[0024] It should be noted that when using this type of post-premixed surface burner, the flowing mixed gas will push the multiple rotating blades 9 to rotate, and the rotating rod 7 will rotate under the drive of the multiple rotating blades 9. At this time, the multiple mixing rods 8 will rotate under the drive of the rotating rod 7, so that the internal gas can be fully mixed, which is more convenient for people to use.

[0025] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
