Description

Technical Field

[0001] The utility model relates to the technical field of industrial furnaces, in particular to an industrial gas burner with a quick-disassembly structure. Background Technique

[0002] A gas burner is an industrial device mainly used for mixing and igniting gas (such as natural gas, liquefied petroleum gas, etc.) with air or oxygen to generate a high-temperature flame. The gas burner is usually divided into various models such as injection burners and premixed burners, and they are widely used in various industrial heating and treatment processes such as industrial furnaces, boilers, heating furnaces, and melting furnaces.

[0003] For some existing gas burners, during use, gas is usually introduced at one end first, and then air is introduced at the other end, so that the two are automatically mixed in a flowing state. Through flowing mixing, the situation of uneven mixing is likely to occur. And for such gas nozzles, multiple bolts are usually used to fix the gas burner to the industrial furnace. When disassembling the burner, it is necessary to rotate multiple bolts, which is rather troublesome.

[0004] Therefore, the technical personnel in this field provide an industrial gas burner with a quick-disassembly structure to solve the problems put forward in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose an industrial gas burner with a quick-disassembly structure. By driving the front-side rotating blades to rotate through the gas flow, the three rear-side rotating blades can be driven to rotate together, thereby accelerating the mixing of gas and air. By setting a fixing mechanism, it is divided into two fixing methods. When removing the burner body, it is not necessary to rotate multiple bolts, which is more convenient.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An industrial gas burner with a quick-disassembly structure includes a ventilation mechanism and a fixing mechanism. The ventilation mechanism includes a burner body, a gas pipe, an air pipe, two rotating rods, and four rotating blades. A storage ring is fixedly sleeved on the front side of the outer end face of the burner body. A plurality of ventilation holes are opened on the inner wall of the storage ring and the outer end face of the burner body. U-shaped plates are fixedly arranged on both sides of the outer end face of the burner body.

[0007] Pulley wheels are rotatably arranged through the front and rear sides of the opposite sides of the two U-shaped plates. Belts are arranged between every two of the four pulley wheels. The fixing mechanism includes a fixing plate, a fixing ring, two sliding grooves, two limiting rods, two pressing plates, two circular rings, and two arc-shaped blocks. Reset springs are fixedly arranged between the two pressing plates and the two sliding grooves.

[0008] Through the above technical solution, by introducing gas into the gas pipe, the gas flow impacts a rotating blade at the front side at this time, thereby driving the rotating blade and the rotating rod at the front side to rotate. During the rotation process, by setting a belt, the rotating rod at the rear side can be driven to rotate together, thereby driving the three rotating blades at the rear side to rotate together. At this time, air enters the inside of the storage ring from the air pipe, and then enters the inside of the burner body through a plurality of ventilation holes, enabling the air and the gas to be preliminarily mixed. When the two reach the position of the three rotating blades, they can be further stirred and mixed together. When it is necessary to remove the burner body, by squeezing two pressing plates towards the middle position while holding the two pressing plates and rotating counterclockwise, when the rotation can no longer continue, the burner body can be removed.

[0009] Further, the gas pipe is fixedly arranged at the middle position of the front end face of the burner body, and the air pipe is embedded at the middle position of the upper side of the outer end face of the storage ring;

[0010] Through the above technical solution, by introducing gas in the horizontal position and through the storage ring and a plurality of ventilation holes, air is introduced at multiple angles, so that the gas and the air can be preliminarily mixed together.

[0011] Further, the two rotating rods are respectively fixedly arranged between two of the four belt pulleys. One of the four rotating blades is fixedly sleeved at the middle position of one outer end face of the front side of the two rotating rods, and the remaining three of the four rotating blades are all fixedly sleeved at the middle position of one outer end face of the rear side of the two rotating rods;

[0012] Through the above technical solution, when the rotating blade at the front side rotates, by setting the belt pulley and the belt, the three rotating blades at the rear side can be driven to rotate together.

[0013] Further, threaded holes are respectively opened at the four corners of the front end face of the fixing plate, and a limiting hole is opened at the middle position of the front end face of the fixing plate;

[0014] Through the above technical solution, the fixing plate is clamped with the fixing ring through the limiting hole. After bolts are inserted into the four threaded holes, the burner body can be connected to the industrial furnace.

[0015] Further, the fixing ring is fixedly sleeved on the outer end face of the burner body away from the storage ring, and the fixing plate is clamped on the outer end face of the fixing ring;

[0016] Through the above technical solution, by clamping the fixing ring and the fixing plate and connecting the burner body to the fixing ring, when removing the burner body, it is not necessary to rotate a plurality of bolts.

[0017] Furthermore, the two sliding grooves are respectively opened at the upper and lower positions of the front end surface of the fixing ring, the two limiting rods are respectively fixedly arranged inside the two sliding grooves, and the two pressing plates are respectively slidably sleeved on the opposite sides of the outer end surfaces of the two limiting rods;

[0018] Through the above technical solution, the pressing plate is limited by the sliding groove and the limiting rod, so that the pressing plate can only move in the vertical direction and its movement range is limited.

[0019] Furthermore, the two circular rings are respectively fixedly arranged at the rear side of the end surfaces on the opposite sides of the two pressing plates, and the two arc blocks are respectively fixedly arranged at the upper side and the lower side of the outer end surface of the fixing ring;

[0020] Through the above technical solution, when the pressing plate is moved, the ring passes through the limiting rod, and its upper end enters the interior of the arc block. At this time, the pressing plate can be held to drive the burner body to rotate.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes an industrial gas burner with a quick-disassembly structure, which introduces gas horizontally and air at multiple angles through a storage ring and multiple air holes, so that when the gas passes through the lower end of the air hole, the gas and the air are preliminarily mixed together, and when the gas is introduced, its airflow impacts the front rotating blade, thereby driving the rotating blade to rotate. By arranging a pulley and a belt, when the front rotating blade rotates, it can drive the three rear rotating blades to rotate together, thereby further mixing the gas and the air, accelerating the mixing efficiency of the two, and making the combustion more complete.

[0023] 2. The utility model proposes an industrial gas burner with a quick-release structure, in which the burner body is fixed to the industrial furnace by a fixing plate and a fixing ring. When the burner body needs to be disassembled, the two pressing plates are squeezed in the middle while the two pressing plates are held and rotated counterclockwise. When the rotation cannot continue, the fixing ring and the burner body can be removed, so that when removing the burner body, there is no need to rotate multiple bolts, which is more convenient.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0033] Refer to Figure 1-6 , an embodiment provided by the present utility model: An industrial gas burner with a quick-release structure, including a ventilation mechanism 1 and a fixing mechanism 2. The ventilation mechanism 1 includes a burner body 101, a gas pipe 102, an air pipe 104, two rotating rods 109, and four rotating blades 110. A storage ring 103 is fixedly sleeved on the front side of the outer end face of the burner body 101. A plurality of ventilation holes 105 are provided on the inner wall of the storage ring 103 and the outer end face of the burner body 101. U-shaped plates 106 are fixedly arranged on both sides of the outer end face of the burner body 101. Pulley 107 is rotatably arranged through the front and rear sides of the opposite sides of the two U-shaped plates 106. A belt 108 is arranged between every two of the four pulleys 107. The gas pipe 102 is fixedly arranged at the middle position of the front side end face of the burner body 101. The air pipe 104 is embedded at the middle position of the upper side of the outer end face of the storage ring 103. The two rotating rods 109 are respectively fixedly arranged between every two of the four pulleys 107. One of the four rotating blades 110 is fixedly sleeved on the middle position of the outer end face of one of the front sides of the two rotating rods 109, and the remaining three of the four rotating blades 110 are fixedly sleeved on the middle position of the outer end face of one of the rear sides of the two rotating rods 109.

[0034] By first introducing fuel gas into the fuel gas pipe 102 and then introducing air into the air pipe 104, at this time the fuel gas enters the inside of the burner body 101 from the horizontal position, and the air enters the inside of the storage ring 103 through the fuel gas pipe 102. By providing a plurality of ventilation holes 105, the air will not all come out from one ventilation hole 105. At this time, under the action of pressure, the air diffuses to other positions of the storage ring 103, and then through the plurality of ventilation holes 105, the air leads to the inside of the burner body 101 in multiple directions, so that the fuel gas and the air can be preliminarily mixed together. And when introducing the fuel gas, the air flow of the fuel gas impacts a front rotating blade 110, thereby driving the rotating blade 110 and the front rotating rod 109 to rotate. During the rotation process, by providing a belt 108, the rear rotating rod 109 can be driven to rotate together, thereby driving the three rear rotating blades 110 to rotate together. When the gas preliminarily mixed together reaches the position of the three rotating blades 110, the three rotating blades 110 stir the gas, so that the fuel gas and the air are further mixed together.

[0035] The fixing mechanism 2 includes a fixing plate 201, a fixing ring 204, two sliding grooves 205, two limiting rods 206, two pressing plates 207, two circular rings 209 and two arc-shaped blocks 210. A return spring 208 is fixedly arranged between each of the two pressing plates 207 and the two sliding grooves 205. Threaded holes 202 are respectively opened at the four corners of the front end face of the fixing plate 201, and a limiting hole 203 is opened at the middle position of the front end face of the fixing plate 201. The fixing ring 204 is fixedly sleeved on the outer end face of the burner body 101 on the side far from the storage ring 103. The fixing plate 201 is snap-fitted on the outer end face of the fixing ring 204. The two sliding grooves 205 are respectively opened at the upper and lower positions on the front end face of the fixing ring 204. The two limiting rods 206 are respectively fixedly arranged inside the two sliding grooves 205. The two pressing plates 207 are respectively slidably sleeved on the opposite sides of the outer end faces of the two limiting rods 206. The two circular rings 209 are respectively fixedly arranged at the positions close to the rear sides of the opposite end faces of the two pressing plates 207. The two arc-shaped blocks 210 are respectively fixedly arranged at the upper and lower positions on the outer end face of the fixing ring 204.

[0036] When initially using the burner body 101, the burner body 101 can be fixed to the industrial furnace by screwing bolts into the threaded holes 202 provided in the fixing plate 201. When it is necessary to remove the burner body 101, while squeezing the two pressing plates 207 towards the middle position, hold the two pressing plates 207 and rotate counterclockwise. When rotation is no longer possible, the burner body 101 can be removed. When squeezing the pressing plates 207, the pressing plates 207 drive the ring 209 to move together. One end of the ring 209 passes through the limiting rod 206 and enters the sliding groove 205, and the other end of the ring 209 enters the inside of the arc-shaped block 210 and leaves the circular groove provided in the limiting hole 203. When the ring 209 leaves this circular groove, the fixing ring 204 still cannot slide out, which can enhance the stability of the connection between the fixing ring 204 and the fixing plate 201 and prevent foreign objects from touching the two pressing plates 207 and causing the fixing ring 204 to slide out. When it is no longer possible to squeeze the two pressing plates 207 towards the middle, hold the two pressing plates 207 and rotate counterclockwise. When rotation is no longer possible, the front end of the arc-shaped block 210 is not blocked by the inner wall of the limiting hole 203, and at this time, the fixing ring 204 can be slid out.

[0037] Working principle: Screw bolts into the threaded holes 202 to connect the fixing plate 201 with the industrial furnace. At this time, first introduce gas into the gas pipe 102, and then introduce air into the air pipe 104. The introduced gas and air are initially mixed together under the action of the ventilation holes 105, and then further mixed together by the three rear rotors 110. At this time, turn on the igniter (not shown in this figure), and the mixed gas can be ignited. The flame sprays out from one end of the burner body 101. When it is necessary to remove the burner body 101, first disconnect the connections with the gas pipe 102 and the air pipe 104. At this time, while squeezing the two pressing plates 207 towards the middle, hold the two pressing plates 207 and rotate counterclockwise. When rotation is no longer possible, the burner body 101 can be slid out.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
