Description

Technical Field

[0001] This utility model relates to the field of ignition device technology, and in particular to a high-efficiency continuous flame device. Background Technology

[0002] Open flame devices are heat energy conversion equipment with an open flame as the core. They achieve functions such as heating, melting, welding, and cutting by burning gaseous, liquid, or solid fuels. They are widely used in industrial manufacturing (metallurgy, chemical industry, ceramics), domestic life (cooking, heating) and special scenarios (flares, experimental equipment).

[0003] Existing open flame devices connect to a gas source via a gas supply component to provide combustion gases, which are then ignited by an ignition component located on the side, thus completing the combustion process.

[0004] However, existing open flame devices do not have other protective mechanisms. As a result, the flame spreads to the surrounding area when it is burning, causing different temperatures to be received by the ion sensing electrodes, which affects the stability of the subsequent ion current and makes it impossible to accurately detect the flame combustion. At the same time, heat may flow to the side ignition components, causing the ignition components to overheat and affecting their service life. Utility Model Content

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

[0006] This application discloses a high-efficiency continuous flame device, comprising:

[0007] Connection components;

[0008] A flamethrower assembly, wherein the connecting component is provided with an assembly groove;

[0009] An open flame assembly is installed in the assembly slot, and the open flame assembly and the flame-spraying assembly are spaced apart.

[0010] A flame guide assembly is disposed on the flame jet assembly, and the free end of the flame guide assembly extends upward above the top of the flame jet assembly to form a flame-blocking zone.

[0011] This application adds a flame guiding component to control the direction of the flame, allowing it to spread upwards as much as possible, ensuring a stable temperature at the top, and thus ensuring the stable operation of the entire open flame device.

[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0013] Furthermore, the flamethrower assembly includes:

[0014] An ejector tube, the bottom of which is connected to a gas source to provide gas;

[0015] A flame nozzle is installed on the top of the ejector tube. The top of the flame nozzle has a first flame port, and the side of the flame nozzle has a second flame port. Both the first and second flame ports are located inside the flame-blocking zone. The beneficial effect of this step is that the flame can be fully combusted through multiple flame ports.

[0016] Furthermore, the nozzle is cylindrical, and the top of the nozzle is provided with a chamfered section, and the first nozzle is opened on the chamfered section;

[0017] The nozzle has a fuel chamber inside, which is connected to the outlet of the ejector tube. The top of the fuel chamber is frustoconical and is connected to the first nozzle. The advantage of this step is that the nozzle and the fuel chamber work together to ensure complete combustion of the fuel.

[0018] Furthermore, the first flame nozzle is perforated;

[0019] The second flame nozzle includes:

[0020] The ignition section is orifice-shaped and mates with the end of the open flame assembly.

[0021] The flame-spraying section has one end connected to the ignition section and the other end extending downward in a spiral;

[0022] The stabilizing section is located at the other end of the flame-spraying section, and the stabilizing section is perforated. The advantage of this step is that multiple flame-spraying ports work together, one for main combustion and the other for auxiliary combustion, which can ensure the stability of combustion.

[0023] Furthermore, the horizontal plane at the center of the ignition segment is lower than the horizontal plane at the center of the first flame nozzle.

[0024] The number of spirals n in the flame-spraying section is less than or equal to 1. The beneficial effect of this step is that it can ensure the completeness of combustion.

[0025] Furthermore, the flame guiding assembly includes:

[0026] An isolation shield is installed on the flamethrower assembly;

[0027] Fins are mounted on the isolation cover, and the fins extend outward at an angle from their connection with the isolation cover;

[0028] A flame-blocking unit is installed on the isolation cover, and the flame-blocking unit and the fins cooperate to form the flame-blocking zone. The beneficial effect of this step is that the flame-blocking component can achieve the effect of flame blocking, that is, reduce the heat from approaching the open flame component.

[0029] Furthermore, the fins are located on the side of the flame-throwing assembly away from the open flame assembly;

[0030] The angle between the fin and the centerline of the flame-spraying assembly is an acute angle. The beneficial effect of 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.

[0031] Furthermore, the fins are at least two in number, with one fin corresponding to the flame stabilizing section and the remaining fin corresponding to the first flame nozzle. The advantage of this step is that the flame direction during gas combustion can be better controlled by using two fins.

[0032] Furthermore, the flame deflector unit includes:

[0033] A support plate is connected at its bottom to the isolation cover, and the support plate is located between the flame-spraying assembly and the open flame assembly;

[0034] A flame deflector is installed on the top of the support plate, and the flame deflector is L-shaped;

[0035] The horizontal section of the flame deflector extends above the flame-spraying assembly to form a flame-deflecting end, and there is a gap between the horizontal section of the flame deflector and the flame nozzle. The vertical section of the flame deflector is located inside the open flame assembly. The beneficial effect of this step is that the flame-deflecting effect can be improved by using an L-shaped flame deflector.

[0036] Furthermore, the open flame assembly includes:

[0037] An ignition electrode is disposed within the connecting assembly;

[0038] The first electrode needle is installed on the top of the ignition electrode;

[0039] A sensing electrode is disposed within the connecting assembly, and the sensing electrode is arranged parallel to the ignition electrode;

[0040] The second electrode needle is installed on top of the sensing electrode;

[0041] The angle between the vertical section of the second electrode needle and the center line of the sensing electrode is no greater than 30 degrees, and the horizontal section of the second electrode needle is located above the top of the nozzle. The beneficial effect of this step is that the working state of this application can be accurately controlled through the corresponding ignition electrode and sensing electrode.

[0058] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0059] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0060] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0061] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0062] Example:

[0063] like Figure 1-5 As shown, this application discloses a high-efficiency continuous flame device, which improves upon existing open flame devices by adding a flame guiding component inside. The fins within the flame guiding component adjust the flame direction of the nozzle, making it point upwards. Combined with the electrode needles of the open flame component, this generates a stable and efficient ion current, ensuring the burner operates normally and stably. Furthermore, to better adjust the heat transfer direction, the flame guiding component also includes a flame baffle plate. The flame baffle plate adjusts the heat direction, directing the heat towards the fins. Figure 2See, it is adjusted to the left to avoid the open flame components from affecting it, thereby better ensuring that the entire device can work stably; this application also designs the nozzle to ensure that the fuel and air are mixed more evenly and the combustion is more complete through different nozzles.

[0064] like Figure 1 , 2 As shown, the specific structure of this application is as follows, including:

[0065] Connection component 1; This connection component 1 is used to install other subsequent components and must be installed inside the heating device. Therefore, this connection component 1 can be a single mounting plate or a combination of multiple components.

[0066] The flame-spraying assembly 2 is installed on the connecting assembly 1. The flame-spraying assembly 2 is a conventional component used to connect to the gas source and provide stable fuel.

[0067] An open flame assembly 3 is installed on the connecting assembly 1, and the open flame assembly 3 and the flame-spraying assembly 2 are spaced apart. The open flame assembly 3 is used for ignition and cooperates with the nozzle of the flame-spraying 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-spraying assembly 2 in this application are parallel to each other, which facilitates installation and can also better control the combustion direction.

[0068] A flame guide assembly 4 is disposed on the flame-spraying assembly 2, and the free end of the flame guide assembly 4 extends upward above the top of the flame-spraying assembly 2 to form a flame-blocking zone 5. The purpose of the flame guide assembly 4 is to control the direction of flame spread, making it as upward as possible. Therefore, the flame guide assembly 4 is positioned opposite the open flame assembly 3, from the attached... Figure 2 From the perspective of the direction of the burner, we should try to avoid it spreading to the right; at the same time, in order to stabilize the ion current and the stable operation of the burner, its height should not be too high.

[0069] The flame guide assembly 4 can be a single plate or a combination of multiple components.

[0070] To ensure the stability of open flame combustion and the completeness of fuel combustion, this application designs the flame-throwing assembly 2, specifically the flame-throwing nozzle 202, with the following structure:

[0071] The ejector tube 201 is connected to a gas source at its bottom to provide gas. Specifically, a gas nozzle, gasket, and other components are installed at its bottom.

[0072] The nozzle 202 is installed on the top of the ejector tube 201. The top of the nozzle 202 has a first nozzle 203, and the side of the nozzle 202 has a second nozzle 204. The first nozzle 203 and the second nozzle 204 are both located inside the flame deflector zone 5. As mentioned above, the heat of combustion is concentrated in the flame deflector zone 5 to ensure the stability of combustion.

[0073] Further explanation is given regarding the first flame nozzle 203 and the second flame nozzle 204. In this application, the first flame nozzle 203 serves as a flame outlet, and the resulting flame direction is upward. Meanwhile, the second flame nozzle 204 is arc-shaped to ensure complete and stable combustion.

[0074] In order to better ensure the completeness of fuel combustion and the stability of combustion, the nozzle 202 in this application is cylindrical, and the top of the nozzle 202 is provided with a chamfered section 205, and the first nozzle 203 is opened on the chamfered section 205.

[0075] The nozzle 202 has a fuel chamber 206 inside, which is connected to the outlet of the ejector tube 201. The top of the fuel chamber 206 is frustoconical and is connected to the first nozzle 203. The fuel chamber 206 is designed with a small top diameter to concentrate the fuel, which is then ejected from the first nozzle 203 and ignited to form stable combustion.

[0076] In one embodiment, the first and second flame nozzles can be conventional flame nozzles.

[0077] In yet another embodiment, such as Figure 3-5 As shown, the design can be applied to the first flame nozzle 203 and the second flame nozzle 204. Specifically, the first flame nozzle 203 is orifice-shaped and serves as the main combustion port, while the subsequent second flame nozzle 204 is arc-shaped and serves as the secondary combustion port.

[0078] The second flame nozzle 204 includes:

[0079] Ignition section 207, which is orifice-shaped and engages with the end of the open flame assembly 3;

[0080] The flame-spraying section 208 has one end connected to the ignition section 207 and the other end extending downward spirally.

[0081] The flame stabilizing section 209 is disposed at the other end of the flame-spraying section 208, and the flame stabilizing section 209 is perforated.

[0082] This application designs the second flame nozzle 204 to form a spiral structure, which provides spiral fuel to facilitate combustion and make combustion more complete. At the same time, this application provides a perforated ignition section 207 and a flame stabilizing section 209, which can stabilize the flame and ensure the stability of the flame combustion.

[0083] In order to ensure stable combustion in the second flame nozzle 204, the horizontal plane at the center of the ignition section 207 in this application is lower than the horizontal plane at the center of the first flame nozzle 203. At the same time, the number of spiral lines n of the flame section 208 is n≤1, which can further ensure the uniformity of combustion.

[0084] To better ensure that the combustion zone, i.e., the heat is kept within a certain area, the flame guiding assembly 4 includes:

[0085] An isolation cover 401 is installed on the flame-spraying assembly 2. The isolation cover 401 is an annular part, which facilitates the subsequent connection of fins, thereby enabling the flame guiding function of the fins to be better realized.

[0086] Fins 402 are mounted on the isolation cover 401, and the fins 402 extend outward at an angle from the connection point with the isolation cover 401; the purpose of the fins 402 is to better control the direction of flame spread, making it as upward as possible, thereby ensuring the stable operation of the burner.

[0087] The flame deflector unit 403 is installed on the isolation cover 401, and the flame deflector unit 403 and the fins 402 cooperate to form the flame deflector zone 5. In this application, the fins 402 are used to reduce the spread of the flame to the surrounding area and guide the flame upward to ensure that the flame concentrates on burning the ion sensing electrode, thereby generating a stable and efficient ion current and ensuring the normal and stable operation of the burner. The flame deflector unit 403 controls the heat and directs it to the left as much as possible to avoid affecting the stable operation of the entire device.

[0088] In order to better achieve flame guidance and control, this application also designs the specific installation position of the fins. Specifically, the fins 402 are located on the side of the flame-spraying assembly 2 away from the open flame assembly 3, while the flame-blocking unit 403 is located on the side of the flame-spraying assembly 2 close to the open flame assembly 3. In this way, 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 complete combustion.

[0089] Meanwhile, the angle between the fin 402 and the center line of the flame-spraying 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 make it extend upward as much as possible.

[0090] like Figure 2As shown, the number of fins 402 in this application is at least two, preferably two, that is, corresponding one-to-one with the first flame nozzle 203 and the second flame nozzle 204. Preferably, there are two fins 402, one of which corresponds to the flame stabilizing section 209 and the remaining fin corresponds to the first flame nozzle 203. By cooperating with the two flame nozzles, the flame guiding operation can be better completed.

[0091] In one embodiment, the flame deflector unit 403 includes:

[0092] The support plate 404 is connected to the isolation cover 401 at its bottom, and the support plate 404 is located between the flame-spraying assembly 2 and the open flame assembly 3;

[0093] A flame deflector 405 is installed on the top of the support plate 404, and the flame deflector 405 is L-shaped;

[0094] The horizontal section of the flame deflector 405 extends above the flame-spraying assembly 2 to form a flame-deflecting end, and there is a gap between the horizontal section of the flame deflector 405 and the flame-spraying nozzle 202. The vertical section of the flame deflector 405 is located inside the open flame assembly 3.

[0095] Regarding the support plate 404 and the flame deflector 405, the two can be integrally formed as a flame deflector unit 403, or they can be welded or bolted together to form a flame deflector unit 403. The flame deflector 405 is L-shaped, and its vertical section is located between the subsequent induction electrode and ignition electrode to prevent flame spread and further ensure the stability during operation.

[0096] To better control the direction of flame spread, the L-shaped flame deflector 405 is further designed. Specifically, the horizontal section of the flame deflector 502 extends above the nozzle of the flame-spraying assembly 2 to form the flame-deflecting end, and a gap is left between the horizontal section of the flame deflector 405 and the fin 402. This avoids affecting combustion and also keeps the heat as far away from the open flame assembly 3 as possible, ensuring the stable operation of the device. Specifically, the flame deflector 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.

[0097] To ensure stable assembly of this application, the specific structure of the connecting component 1 is as follows:

[0098] Mounting base 101;

[0099] A pressure plate 102 is disposed on one side of the mounting base 101, and an assembly groove 103 that mates with the open flame assembly 3 is provided on the inner side of the pressure plate 102.

[0100] The bracket 104 is disposed on the other side of the mounting base 101.

[0101] In this application, the bracket 104 is a plate with a groove, on which screws can be installed to ensure the stability of the connection. Meanwhile, the pressure plate 102 in this application is for the subsequent installation of the open flame assembly 3. Therefore, it is preferred that two pressure plates 102 are arranged at intervals. At the same time, the opposite sides of the two pressure plates 102 are provided with assembly grooves 103, and then screws are tightened to ensure the stability of the structure.

[0102] To provide a stable ion current, this application designs an open flame assembly 3, wherein the open flame assembly 3 includes:

[0103] The ignition electrode 301 is disposed within the connecting assembly 1, specifically within the assembly slot 103;

[0104] The first electrode needle 302 is installed on the top of the ignition electrode 301;

[0105] The sensing electrode 303 is disposed within the connecting assembly 1, and the sensing electrode 303 is arranged parallel to the ignition electrode 301. The sensing electrode and the ignition electrode can be existing structures, used to realize the functions of ignition and flame detection.

[0106] The second electrode needle 304 is installed on the top of the sensing electrode 303;

[0107] The 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.

[0108] Specifically, the first electrode needle 302 and the second electrode needle 304 cooperate with each other to achieve a stable ion current. The sensing electrode and the ignition electrode can be existing structures used to achieve the functions of ignition and flame detection.

[0109] The working process of this application:

[0110] In use, the flame-spraying assembly is connected to the combustion gas source, which can be done through a conduit. Then, the open flame assembly is energized, meaning the first and second electrode needles work together to form a stable ion flow, igniting the combustion gas. At this time, the first and second flame-spraying nozzles emit flames, which are guided by fins to minimize the flame's spread to the surrounding area and guide it upwards, ensuring that the flame concentrates on burning the electrodes, thereby generating a stable and efficient ion current and ensuring the burner operates normally and stably. 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.
