[0001] This application relates to the field of hydrogen-oxygen flame cutting technology, and in particular to a hydrogen-oxygen flame cutting energy medium flow device. Background Technology

[0002] Currently, hydrogen-oxygen flame cutting technology is widely used in the cutting of conventional steel billets due to its advantages such as narrow kerf, smooth and clean cut, and low metal consumption.

[0003] However, existing hydrogen-oxygen flame cutting technology still has some problems. For example, when cutting thicker or more complex steel billets, the flame of hydrogen-oxygen combustion is cone-shaped and its diameter is relatively smaller than that of alkane fuels. In addition, the preheating hot spot of complex steel billets is not unique, which leads to the problem of interruption of the preheating opening during cutting. As a result, the quality of the lower half of the section of the thick billet is poor. Utility Model Content

[0005] To achieve the above objectives, this application provides an oxyhydrogen flame cutting energy medium flow device, which is connected to a cutting torch via a pipeline. The oxyhydrogen flame cutting energy medium flow device includes a manifold, and the manifold has multiple channels inside. The multiple channels include an oxyhydrogen channel, an auxiliary gas channel, and a combustion-supporting oxygen channel.

[0009] Optionally, when cutting thinner steel billets, the diameter ratio of the auxiliary gas passage to the hydrogen-oxygen passage is b, and 0.09≤b≤0.13.

[0010] Optionally, the hydrogen-oxygen flame cutting energy medium flow device further includes two second valves, which are respectively located at the inlet end of the hydrogen-oxygen channel and the inlet end of the auxiliary gas channel.

[0011] Optionally, the multiple channels may also include a cutting oxygen channel, wherein the inlet end of the cutting oxygen channel is connected to the cutting gun and the outlet end is connected to the cutting gun.

[0013] Optionally, in the second direction, the distance between the second combustion-supporting vertical section and the hydrogen-oxygen channel is less than the distance between the first combustion-supporting vertical section and the hydrogen-oxygen channel.

[0014] Optionally, the multiple channels further include two processing channels, which are coaxial with the diversion section and the combustion-supporting section, respectively.

[0025] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Figure 1 This is a schematic diagram of the overall structure of an oxyhydrogen flame cutting energy medium flow device proposed in an embodiment of this application; Figure 2 for Figure 1 A cross-sectional structural diagram of the Chinese embodiment.

[0027] It should be noted that for steel billets of conventional steel grades and thicknesses, the thickness is mostly between 100 and 300 mm. For steel billets with a thickness greater than 400 mm or complex steel grades currently appearing on the market, traditional oxyhydrogen flame cutting technology will cause the preheating opening to be interrupted, resulting in poor cutting quality.

[0028] For ease of explanation, steel billets with a thickness of less than 400 mm can be referred to as thinner steel billets, and steel billets with a thickness of ≥400 mm can be referred to as thicker steel billets.

[0029] refer to Figure 1 and Figure 2This application provides a hydrogen-oxygen flame cutting energy medium flow device, which is connected to the cutting gun through a pipeline. The hydrogen-oxygen flame cutting energy medium flow device may include a manifold 1, and the manifold 1 has multiple channels inside. The multiple channels may include a hydrogen-oxygen channel 11, an auxiliary gas channel 12, and a combustion-supporting oxygen channel 13. The outlet end of the hydrogen-oxygen channel 11 is connected to the cutting gun, and the inlet end is supplied with hydrogen and oxygen. The outlet end of the auxiliary gas channel 12 is connected to the hydrogen-oxygen channel 11, and the inlet end is supplied with auxiliary gas. The outlet end of the combustion-supporting oxygen channel 13 is connected to the cutting gun, and the inlet end is supplied with combustion-supporting oxygen.

[0030] The hydrogen-oxygen flame cutting energy medium flow device proposed in this application embodiment, in use, hydrogen and oxygen are introduced into hydrogen-oxygen channel 11, auxiliary gas is introduced into auxiliary gas channel 12, and combustion-supporting oxygen is introduced into combustion-supporting oxygen channel 13. Hydrogen, oxygen, and auxiliary gas are mixed in hydrogen-oxygen channel 11 and delivered to the cutting torch. At the same time, combustion-supporting oxygen is synchronously delivered to the cutting torch. Then, the workpiece is preheated by ignition. After preheating, cutting is performed. Combustion-supporting oxygen can further increase the flame temperature, diameter, and length of the cutting torch during cutting, ensuring the success rate of cutting the opening on the first attempt when cutting thick steel billets, preventing the problem of preheating opening interruption, and resulting in good cutting end face quality.

[0031] It should be noted that before cutting, cutting oxygen needs to be supplied to the cutting gun. The cutting oxygen pipeline and the flow device should be connected to the cutting gun independently.

[0032] Furthermore, the multiple channels can also include a cutting oxygen channel, with its inlet and outlet connected to the cutting gun. In this way, the flow device can be equipped with a separate cutting oxygen channel to supply cutting oxygen to the cutting gun. The cutting gun and external pipelines can be completely connected using the flow device. The integrated design of the flow device is compact, and during installation, it is only necessary to connect each pipeline to the channel port on the flow device, which is convenient and quick. Of course, a cutting oxygen valve can also be installed on the cutting oxygen channel.

[0033] refer to Figure 2 In an exemplary embodiment, the hydrogen-oxygen flame cutting energy medium flow device may further include a diversion valve 2, which is disposed on the manifold 1; the multiple channels may further include a diversion channel 14, one end of which is connected to the hydrogen-oxygen channel 11 and the other end of which is connected to the combustion-supporting oxygen channel 13; wherein, in the extending direction of the hydrogen-oxygen channel 11, the diversion channel 14 is located between the auxiliary gas channel 12 and the outlet end of the hydrogen-oxygen channel 11; the diversion valve 2 blocks or opens the diversion channel 14.

[0034] Specifically, when cutting thinner steel billets, there is no need to introduce combustion oxygen. The diversion valve 2 can be opened, and combustion oxygen is no longer introduced into the combustion oxygen channel 13. After the hydrogen and oxygen are mixed with the auxiliary fuel in the hydrogen and oxygen channel 11, part of it flows into the diversion channel 14 and is delivered to the cutting torch from the outlet end of the combustion oxygen channel 13. In this way, the mixed gas of hydrogen and oxygen and the auxiliary fuel is delivered to the cutting torch through two channels, which greatly increases the gas flow rate, thereby extending the flame length during cutting and resulting in better cutting effect. At the same time, delivering the mixed gas to the cutting torch through two channels can further reduce the combustion speed of hydrogen and oxygen, thereby reducing the probability of backfire and the damage caused by backfire, making it safer to use.

[0035] In an exemplary embodiment, the hydrogen-oxygen flame cutting energy medium flow device may further include a first valve 3, which is disposed at the inlet end of the combustion-supporting oxygen channel 13.

[0036] Specifically, with the addition of the first valve 3, the flow of combustion-supporting oxygen into the circulation device can be controlled through the first valve 3, making it more convenient and faster.

[0037] Furthermore, by adjusting the opening of the first valve 3, the gas pressure and flow rate of the combustion oxygen can be adjusted, thereby adjusting the flame state. For example, during preheating, the combustion oxygen pressure can be adjusted to adjust the flame to a neutral flame state; during cutting, the combustion oxygen pressure can be adjusted to increase the flame temperature and rigidity.

[0038] In an exemplary embodiment, when cutting a thicker steel billet, the diameter ratio of the auxiliary gas passage 12 to the hydrogen-oxygen passage 11 is a, and 0.14≤a≤0.29.

[0039] Specifically, the traditional auxiliary gas to hydrogen-oxygen ratio is about 0.13, which is only suitable for cutting thinner steel billets. When cutting thicker steel billets, 'a' needs to be increased. For example, 'a' can be 0.14, 0.18, 0.21, 0.24, and 0.29, etc. This can increase the auxiliary gas flow rate, extend the flame airflow length, and improve the cutting quality of thick billets. The increased flame diameter will also increase, which can further reduce the tempering rate and increase the cutting success rate when preheating the opening for cutting complex billet shapes.

[0040] In an exemplary embodiment, when cutting a thinner steel billet, the diameter ratio of the auxiliary gas passage 12 to the hydrogen-oxygen passage 11 is b, and 0.09≤b≤0.13.

[0041] Specifically, when cutting thinner steel billets, the initial value of the traditional auxiliary gas to hydrogen-oxygen ratio needs to be reduced by decreasing b. For example, b can be 0.09, 0.10, 0.11, 0.12, and 0.13, etc. This can reduce the flow rate of the auxiliary gas, thereby reducing the amount of auxiliary gas used, reducing the carbon emission index in the flame, and reducing energy consumption.

[0042] It should be noted that a and b are the diameter ratios of the auxiliary gas passage 12 and the hydrogen-oxygen passage 11 under different usage conditions in this application.

[0043] In an exemplary embodiment, the hydrogen-oxygen flame cutting energy medium flow device may further include two second valves, which are respectively disposed at the inlet end of the hydrogen-oxygen channel 11 and the inlet end of the auxiliary gas channel 12.

[0044] This allows for further adjustment of the diameter ratio between the auxiliary gas passage 12 and the hydrogen-oxygen passage 11 by adjusting the opening of the second valve, making it more convenient to use.

[0045] Both the first valve 3 and the second valve can be common needle valves, gate valves, or ball valves.

[0046] refer to Figure 2 In an exemplary embodiment, the hydrogen-oxygen channel 11 extends along a first direction; the diversion channel 14 may include a diversion horizontal section 141 and a diversion vertical section 142 connected in sequence, the diversion horizontal section 141 extending along a second direction and communicating with the hydrogen-oxygen channel 11, the second direction being perpendicular to the first direction, and the diversion vertical section 142 extending along the first direction; the combustion-supporting oxygen channel 13 may include a first combustion-supporting vertical section 131, a combustion-supporting horizontal section 132, and a second combustion-supporting vertical section 133 connected in sequence, the first combustion-supporting vertical section 131 and the second combustion-supporting vertical section 133 both extending along the first direction, the combustion-supporting horizontal section 132 extending along the second direction, and the inlet end of the combustion-supporting oxygen channel 13 located on the first combustion-supporting vertical section 131; wherein, the diversion vertical section 142 and the second combustion-supporting vertical section 133 are coaxial and connected.

[0047] In an exemplary embodiment, in the second direction, the distance between the second combustion-supporting vertical section 133 and the hydrogen-oxygen channel 11 is less than the distance between the first combustion-supporting vertical section 131 and the hydrogen-oxygen channel 11.

[0048] It should be noted that, as Figure 2 As shown, the first direction is the X direction, and the second direction is the Y direction. For ease of explanation, the first direction is denoted as vertical and the second direction as horizontal.

[0049] Specifically, the outlet end of the combustion-supporting oxygen channel 13 arranged in the above manner is close to the outlet end of the hydrogen-oxygen channel 11, which facilitates the connection of the cutting torch to the combustion-supporting oxygen channel 13 and the hydrogen-oxygen channel 11 through a relatively compact pipeline.

[0050] refer to Figure 2 In an exemplary embodiment, the multiple channels may further include two processing channels 15, which are coaxial with the diversion section 141 and the combustion-supporting section 132, respectively. The first end of the processing channel 15 is connected to the corresponding diversion section 141 or the corresponding combustion-supporting section 132, and the second end is connected to the outside of the manifold 1. The hydrogen-oxygen flame cutting energy medium flow device may further include two pipe plugs 4, which are respectively disposed at the second end of the two processing channels 15.

[0051] Specifically, such as Figure 2 As shown, the diversion section 141 and the combustion-supporting section 132 are located inside the manifold 1 and have no ports connecting to the outside of the manifold 1, which is inconvenient for processing. Therefore, two processing channels 15 can be added to the manifold 1. The two processing channels 15 are coaxial with the diversion section 141 and the combustion-supporting section 132 respectively. The first end of the processing channel 15 is connected to the corresponding diversion section 141 or the corresponding combustion-supporting section 132, and the second end is connected to the outside of the manifold 1. In this way, the diversion section 141 and the combustion-supporting section 132 can be processed from the processing channel 15.

[0052] Furthermore, two pipe plugs 4 are respectively installed at the second end of the two processing channels 15 to seal the second end of the processing channels 15 and prevent internal gas from leaking out of the manifold 1 from the processing channels 15.

[0053] The specific working principle of this solution is as follows: Preheating process: Open the first valve 3 and the second valve; check the sealing of each valve to ensure that the system is well sealed; adjust the opening of the two second valves to make the ratio of the auxiliary gas flow path to the hydrogen-oxygen flow path meet the requirements; adjust the opening of the first valve 3 to change the oxygen pressure for combustion, thereby adjusting the flame to a neutral flame state; ignite to generate a stable flame and preheat the workpiece.

[0054] Cutting process: After preheating, open the cutting oxygen valve to cut the workpiece. Adjust the opening of the second valve to control the auxiliary gas flow, thereby reducing the combustion rate of hydrogen and oxygen and the probability of backfire. Adjust the opening of the first valve 3 to change the combustion oxygen pressure, thereby increasing the flame temperature and flame rigidity. Monitor the flame temperature and rigidity in real time to ensure that the flame temperature reaches the target temperature and the rigidity meets the requirements. An infrared thermometer can be used to measure the flame temperature, and the flame rigidity can be judged by observing the flame shape and sound. Then, proceed with the cutting. After cutting, close the cutting oxygen valve, the second valve on the hydrogen-oxygen channel, and the first valve 3 in sequence. Finally, close the second valve on the auxiliary gas to achieve hydrogen-oxygen flameout. Reignite the flame for the next cutting operation and shut off the flame after the cutting operation. Repeat the ignition and flameout process until processing stops.

[0055] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
