Description

Technical Field

[0001] The invention relates to the technical field of ignition devices, in particular to a high-efficiency long-burning flame device. Background Art

[0002] The open flame device is a thermal energy conversion device with an open flame as its core. It achieves functions such as heating, smelting, welding, and cutting by burning gaseous, liquid, or solid fuels. It is widely used in industrial manufacturing (metallurgy, chemical industry, ceramics), civil life (cooking, heating), and special scenarios (torches, experimental equipment), etc.

[0003] The existing open flame device is connected to the fuel gas source through a gas supply component to provide combustion gas, and then the ignition component located on the side performs ignition to complete the combustion work.

[0004] However, the existing open flame device is not equipped with other protective mechanisms. When the flame is burning, it will spread to the surroundings, causing the ion sensing electrode to receive different temperatures, affecting the stability of the subsequent ion current, and failing to accurately detect the flame combustion conditions; at the same time, heat may flow to the side ignition component, causing the ignition component to overheat and shorten its service life. Summary of the invention

[0005] The purpose of the present invention is to provide a high-efficiency long-lasting open flame device, which solves the technical problem in the prior art that the flame in the open flame device is easy to spread everywhere, affecting the stable operation of the entire open flame device.

[0007] The present application adds a flame guide assembly to control the direction of the flame so that it spreads upward as much as possible, ensuring the temperature at its top is stable, thereby ensuring the stable operation of the entire open flame device.

[0008] Based on the above technical solution, the embodiment of the present application can also be improved as follows: Furthermore, the flame spraying assembly comprises: An ejector pipe, the bottom of which is connected to a fuel gas source to provide fuel gas; A flamethrower is installed on the top of the ejector tube, a first flamethrower is provided on the top of the flamethrower, and a second flamethrower is provided on the side of the flamethrower, the first flamethrower and the second flamethrower are both located inside the flame blocking area, and the beneficial effect of adopting this step is that the flame can be fully burned by multiple flamethrowers.

The beneficial effect of adopting this step is that multiple flame spraying ports are coordinated, one as the main combustion and the other as the auxiliary combustion, so that the stability during combustion can be ensured.

[0011] Furthermore, the horizontal plane where the center of the ignition section is located is lower than the horizontal plane where the center of the first flame outlet is located; The number of spiral lines of the flame spraying section is n, where n≤1.

The beneficial effect of this step is that the flame blocking effect can be achieved through the flame blocking component, that is, reducing the heat approaching the open flame component.

[0013] Further, the fin is located on a side of the flame spraying assembly away from the open flame assembly; The angle between the fin and the center line of the flame-spraying assembly is an acute angle. The beneficial effect of adopting this step is that the fin forms a structure similar to an inverted figure eight, which can control the flame, reduce its outward spread, and ensure that the flame concentrates on burning the electrode.

[0026] like Figure 1 , 2 As shown, the specific structure of this application is as follows, including: Connecting assembly 1; the connecting assembly 1 is used to install other subsequent components and is installed in the heating device at the same time, so the connecting assembly 1 can be a single mounting plate or an assembly formed by the cooperation of multiple components; The flame spraying assembly 2 is installed on the connecting assembly 1. The flame spraying assembly 2 is a conventional component, which is used to connect the gas source and provide stable fuel; The open flame assembly 3 is installed on the connecting assembly 1, and the open flame assembly 3 is spaced apart from the flame spray assembly 2; the open flame assembly 3 is used for ignition, and cooperates with the flame spray port of the flame spray assembly 2 to complete ignition and combustion, thereby achieving stable heating. In order to ensure the stability of combustion, the open flame assembly 3 and the flame spray assembly 2 in the present application are parallel to each other, which is convenient for installation and can also better control the combustion direction; The flame guide assembly 4 is arranged on the flame spray assembly 2, and the free end of the flame guide assembly 4 extends upward to be higher than the top of the flame spray assembly 2 to form a flame blocking area 5; the purpose of the flame guide assembly 4 is to control the spreading direction of the flame and make it as upward as possible, so the flame guide assembly 4 is opposite to the open flame assembly 3, and the flame guide assembly 4 is arranged on the upper side of the flame spray assembly 2. Figure 2 From the direction of the center, try to avoid it spreading to the right; at the same time, for the stability of the ion current and the stable operation of the burner, its height should not be too high.

[0027] The flame guide assembly 4 can be a single plate or a combination of multiple components.

[0028] In order to ensure the stability of open flame combustion and the sufficiency of fuel combustion, the present application designs a flame spray assembly 2, specifically a flame spray nozzle 202, the structure of which is as follows, including: The ejector tube 201, the bottom of which is connected to the fuel gas source to provide fuel gas, and specifically, a gas nozzle, a gasket and other components are installed at the bottom; The flame nozzle 202 is installed on the top of the ejector tube 201, and a first flame outlet 203 is provided on the top of the flame nozzle 202, and a second flame outlet 204 is provided on the side of the flame nozzle 202. The first flame outlet 203 and the second flame outlet 204 are both located inside the flame barrier zone 5. Combined with the above, the heat of combustion is concentrated in the flame barrier zone 5 through the flame barrier zone 5 to ensure the stability of combustion.

[0029] The first flame vent 203 and the second flame vent 204 are further described. The first flame vent 203 in the present application is used as a flame outlet, and the flame formed is directed upward; meanwhile, the second flame vent 204 is arc-shaped to ensure sufficient and stable combustion.

[0030] In order to better ensure the sufficiency of fuel combustion and the stability during combustion, the flame nozzle 202 in the present application is cylindrical, and a chamfered section 205 is provided on the top of the flame nozzle 202, and the first flame port 203 is opened on the chamfered section 205; A fuel chamber 206 is provided inside the flamethrower 202, and the fuel chamber 206 is connected to the outlet of the ejector tube 201. The top of the fuel chamber 206 is in a frustum shape, and the top of the fuel chamber 206 is connected to the first flamethrower 203. The fuel chamber 206 is designed with a small top diameter so that the fuel is concentrated and then ejected from the first flamethrower 203 and then ignited to form stable combustion.

[0031] In one embodiment, the first flame emitting port and the second flame emitting port may be conventional flame emitting ports.

[0032] In yet another embodiment, Figure 3-5As shown, the first flame ejection port 203 and the second flame ejection port 204 can be designed. Specifically, the first flame ejection port 203 is hole-shaped and serves as a main combustion port, and the subsequent second flame ejection port 204 is arc-shaped and serves as a secondary combustion port. The second flame outlet 204 comprises: An ignition section 207, wherein the ignition section 207 is hole-shaped and cooperates with the end of the open flame assembly 3; A flame spraying section 208, one end of which is connected to the ignition section 207, and the other end of which spirally extends downward; The fire stabilizing section 209 is disposed at the other end of the flame spraying section 208, and the fire stabilizing section 209 is hole-shaped.

[0033] The present application designs the second flame outlet 204 to form a spiral structure, thereby providing spiral fuel to facilitate combustion and make the combustion more complete. At the same time, the present application is provided with a hole-shaped ignition section 207 and a fire stabilization section 209, which can stabilize the flame and ensure the stability of the flame during combustion.

[0034] In order to ensure stable combustion of the second flame emitting port 204, the horizontal plane where the center of the ignition section 207 in the present application is located is lower than the horizontal plane where the center of the first flame emitting port 203 is located. At the same time, the number of spiral lines n of the flame emitting section 208 is n≤1, which can further ensure the uniformity of combustion.

[0035] In order to better ensure the combustion area, that is, the heat is in a certain area, the flame guide assembly 4 includes: An isolation cover 401 is installed on the flame spraying assembly 2. The isolation cover 401 is a ring-shaped part, which is convenient for subsequent fin connection, so as to better realize the flame guide function of the fin; The fin 402 is mounted on the isolation cover 401 and extends outwardly from the connection between the fin 402 and the isolation cover 401. The purpose of the fin 402 is to better control the spreading direction of the flame and make it as upward as possible, thereby ensuring the stable operation of the burner.

[0036] The flame blocking unit 403 is installed on the isolation cover 401, and the flame blocking unit 403 cooperates with the fins 402 to form the flame blocking area 5. The present application uses the fins 402 to reduce the spread of flames to the periphery, guide the flames upward, and ensure that the flames concentrate on burning the ion sensing electrodes, thereby generating a stable and efficient ion current, ensuring the normal and stable operation of the burner, and the flame blocking unit 403 controls the heat to make it as far to the left as possible to avoid affecting the stable operation of the entire device.

[0037] In order to better achieve the guidance control of the flame, the present application also designs the specific installation position of the fin. Specifically, the fin 402 is located on the side of the flame spraying assembly 2 away from the open flame assembly 3, and the flame blocking unit 403 is located on the side of the flame spraying assembly 2 close to the open flame assembly 3, so that one side guides the flame and the other side blocks the flame, so that the flame burns in a certain area, thereby ensuring stable and sufficient combustion; At the same time, the angle between the fin 402 and the center line of the flame spray assembly 2 is an acute angle, that is, the fin 402 is combined to form a structure similar to an inverted figure eight, so as to control the spread of the flame and extend it upward as much as possible.

[0038] like Figure 2 As shown, the number of fins 402 in the present application is at least two, preferably two, that is, one-to-one corresponding to the first flamethrower 203 and the second flamethrower 204. Preferably, the fins 402 are two, one of which is matched with the fire stabilizing section 209, and the remaining fins 402 are matched with the first flamethrower 203. The cooperation with the two flamethrowers can better complete the flame guide operation.

[0039] In one embodiment, the flame blocking unit 403 includes: A support plate 404, the bottom of which is connected to the isolation cover 401, and the support plate 404 is located between the flame spraying assembly 2 and the open flame assembly 3; A flame baffle 405 is installed on the top of the support plate 404, and the flame baffle 405 is L-shaped; The horizontal section of the flame baffle plate 405 extends to above the flame spraying assembly 2 to form a flame baffle end, and a gap is left between the horizontal section of the flame baffle plate 405 and the flame spraying nozzle 202 , and the vertical section of the flame baffle plate 405 is located in the open flame assembly 3 .

[0040] Regarding the support plate 404 and the flame baffle plate 405, the two can be integrally formed into a flame baffle unit 403, or can be welded or bolted to each other to form a flame baffle unit 403; the flame baffle plate 405 is L-shaped, and its vertical section is located between the subsequent induction electrode and the ignition electrode to prevent the flame from spreading and further ensure stability during operation.

[0041] In order to better control the direction of flame spread, the L-shaped flame baffle plate 405 is further designed. Specifically, the horizontal section of the flame baffle plate 502 extends to above the flame outlet of the flame-spraying assembly 2 to form the flame baffle end, and a gap is left between the horizontal section of the flame baffle plate 405 and the fin 402. This can avoid affecting the combustion, while also controlling the heat as far away from the open flame assembly 3 as possible to ensure the stable operation of the device. Specifically, the flame baffle unit 403 can block the flame, that is, control the heat at the open flame assembly 3, and can ensure the stable operation of the open flame assembly 3 as much as possible.

[0042] In order to ensure that the present application can be stably assembled, the specific structure of the connecting component 1 is as follows, including: Mounting seat 101; A pressure plate 102 is disposed on one side of the mounting seat 101, and an assembly groove 103 matching with the open flame assembly 3 is disposed on the inner side of the pressure plate 102; The bracket 104 is disposed on the other side of the mounting base 101 .

[0043] The bracket 104 in the present application is a plate with grooves, on which screws can be installed to ensure the stability of the connection. At the same time, the pressure plate 102 in the present application is for the subsequent installation of the open flame component 3, so it is preferred that the two pressure plates 102 are arranged at intervals, and at the same time, the opposite sides of the two pressure plates 102 are provided with assembly grooves 103, which are then tightened by screws to ensure the stability of the structure.

[0044] In order to provide a stable ion current, the present application is designed for an open flame component 3, wherein the open flame component 3 includes: The ignition electrode 301 is disposed in the connection assembly 1, specifically, in the assembly groove 103; A first electrode needle 302 is installed on the top of the ignition electrode 301; The sensing electrode 303 is disposed in the connection assembly 1, and the sensing electrode 303 is disposed in parallel with the ignition electrode 301. The sensing electrode and the ignition electrode may be existing structures, and are used to realize the functions of ignition and flame detection; The second electrode needle 304 is installed on the top of the sensing electrode 303; The included angle between the vertical section of the second electrode needle 304 and the center line of the sensing electrode 303 is no greater than 30 degrees, and the horizontal section of the second electrode needle 304 is located above the top of the flame nozzle 202 .

[0045] Specifically, the first electrode needle 302 and the second electrode needle 304 cooperate with each other to realize a stable ion current. The sensing electrode and the ignition electrode can be existing structures for realizing the functions of ignition and flame detection.

[0046] Working process of this application: When in use, the flamethrower assembly is connected to the gas source of the combustion gas, which may be connected through a conduit, and then the open flame assembly is energized, that is, the first electrode needle and the second electrode needle cooperate with each other to form a stable ion flow to ignite the combustion gas; at this time, the first flamethrower and the second flamethrower spray flames, and the fins are used to guide the flame to minimize the spread of the flame to the surrounding area and guide it upward to ensure that the flame concentrates on burning the electrode, thereby generating a stable and efficient ion current to ensure the normal and stable operation of the burner; at this time, the flame blocking assembly starts to work to prevent the flame from affecting the open flame assembly and extend the service life of the entire device.
