Description

Technical Field

[0001] This application relates to the technical field of oxidation diffusion furnace devices, and in particular to an automatically adjustable hydrogen-oxygen combustion chamber. Background Technology

[0002] Diffusion technology refers to the methods of processing and treating various materials by utilizing the principle of diffusion to achieve certain objectives.

[0003] Regarding the aforementioned technologies, the diffusion process requires the use of hydrogen-oxygen combustion for wet oxygen oxidation. Hydrogen and oxygen need to be introduced into the ignition chamber. Generally, oxygen and hydrogen are regulated and controlled separately and need to be mixed in a certain ratio. During use, the oxygen flow rate and hydrogen flow rate need to be adjusted sequentially. Furthermore, when the oxygen flow rate changes, the hydrogen flow rate also needs to be adjusted. This makes the adjustment process cumbersome and the adjustment of hydrogen has a certain lag, which may affect the hydrogen-oxygen balance in the chamber and lead to incomplete hydrogen-oxygen combustion. Summary of the Invention

[0004] In order to achieve hydrogen-oxygen balance in the ignition chamber and ensure complete combustion of hydrogen and oxygen within the chamber, the purpose of this application is to provide an automatically adjustable hydrogen-oxygen combustion chamber.

[0005] The automatic adjustable hydrogen-oxygen combustion chamber provided in this application adopts the following technical solution:

[0006] An automatically adjustable hydrogen-oxygen combustion chamber includes a chamber with an outlet at one end and a hydrogen input pipe and an oxygen input pipe connected to the other end of the chamber. A fan is rotatably connected to the inner wall of the oxygen input pipe. A flow-limiting component for limiting the flow of hydrogen is provided in the hydrogen input pipe. A transmission mechanism for controlling the flow-limiting effect of the flow-limiting component according to the flow speed of the fan is provided between the hydrogen input pipe and the oxygen input pipe.

[0007] By adopting the above technical solution, oxygen can be delivered into the cavity through the oxygen input pipe, and the flow limiting component can control the flow rate of hydrogen in the hydrogen input pipe. When oxygen flows through the impeller, the impeller can control the flow limiting component's restriction effect on hydrogen through the transmission mechanism. Thus, not only can the hydrogen flow rate be adjusted according to the oxygen flow rate, but the automatic adjustment of the hydrogen flow rate can also be achieved.

[0008] Optionally, the flow-limiting component includes a sealing plate fixed to the inner wall of the hydrogen input pipe, the sealing plate having an opening for the hydrogen to flow through, a baffle plate inside the hydrogen input pipe for changing the size of the opening, an adjusting gear ring rotatably connected to the hydrogen input pipe and arranged around the hydrogen input pipe, the baffle plate being placed inside the hydrogen input pipe and fixed to the inner arc surface of the adjusting gear ring, a reset component on the adjusting gear ring for keeping the baffle plate blocking the opening, and a drive component for driving the adjusting gear ring to rotate.

[0009] By adopting the above technical solution, when oxygen is introduced into the oxygen inlet pipe, the transmission mechanism can control the adjusting gear ring through the drive component, causing the adjusting gear ring to rotate around the hydrogen inlet pipe. This causes the baffle plate to remove its obstruction of the gas hole, allowing hydrogen to enter the cavity through the gas hole. The higher the oxygen flow rate, the greater the force exerted by the drive component on the adjusting gear ring, thus increasing the exposed area of ​​the gas hole and increasing the hydrogen flow rate. When oxygen supply stops, the reset component can quickly reset the baffle plate and block the gas hole, thereby quickly stopping the hydrogen supply into the cavity.

[0010] Optionally, the drive assembly includes a transmission tube, which is coaxially arranged with and fixedly connected to the wind turbine. The transmission mechanism further includes a gear set for transmitting power from the transmission tube to the adjusting gear ring.

[0011] By adopting the above technical solution, the force on the wind turbine can be quickly transmitted to the adjusting gear ring through the transmission effect of the transmission pipe and gear set.

[0012] Optionally, the reset assembly includes a reset block fixed to the end face of the adjusting gear ring, and a spring for connecting the reset block and the hydrogen input pipe is fixedly connected between the two.

[0013] By adopting the above technical solution, the adjusting toothed ring and the hydrogen input pipe can be kept relatively stationary under the action of the spring. When the adjusting toothed ring is subjected to force, the spring can be stretched quickly, and the spring has good extensibility and can be used multiple times.

[0014] Optionally, the gear set includes a first bevel gear fixedly connected to the end of the transmission tube, a second bevel gear meshing with one side of the first bevel gear, and a transmission roller coaxially and fixedly connected to the second bevel gear. A pipe clamp is installed on the side wall of the transmission roller, coaxially with the transmission roller. A rack is fixedly connected to the upper part of the pipe clamp along the outer side wall of the pipe clamp, and the rack meshes with the adjusting toothed ring. An adjusting component for adjusting and fixing the distance between the transmission roller and the hydrogen input pipe is provided between the transmission roller and the hydrogen input pipe.

[0015] By adopting the above technical solution, the power on the transmission tube can be transmitted to the transmission roller through the transmission effect of the first bevel gear and the second bevel gear, causing the transmission roller to rotate. This causes the pipe clamp on the transmission roller to rotate together with the transmission roller, which in turn causes the rack on the pipe clamp to drive the adjusting gear ring to start rotating. Furthermore, the speed of the adjusting gear ring can be changed by replacing pipe clamps of different diameters, thereby changing the flow rate ratio of hydrogen and oxygen.

[0016] Optionally, the transmission tube includes a first column and a second column, the second column being slidably connected within the first column, and a fixing member for fixing the two columns is provided between the first column and the second column.

[0017] By adopting the above technical solution, the length of the transmission tube can be quickly adjusted by sliding the second column within the first column.

[0018] Optionally, the fixing member is configured as a fixing bolt, and the side wall of the second column is provided with multiple threaded holes arranged along the axis of the transmission tube, and the shank of the fixing bolt is threaded into one of the threaded holes.

[0019] By adopting the above technical solution, the length of the transmission tube can be quickly fixed by rotating the fixing bolt, and the length of the transmission tube can be changed by screwing the fixing bolt into the threaded hole at different positions.

[0020] Optionally, the adjusting assembly includes a connecting post located at the end of the transmission tube. The connecting post is coaxially arranged with the transmission roller, and one end of the connecting post is rotatably connected to the transmission roller. A rotating rod is fixedly connected to the other end of the connecting post. The connecting post is arranged perpendicular to the connecting post. A threaded cylinder is rotatably connected to the end of the rotating rod away from the connecting post. The threaded cylinder is coaxially arranged with the rotating rod. A stud is threadedly connected to the end of the threaded cylinder away from the rotating rod. The stud is coaxially arranged with the threaded cylinder and is fixedly connected to the hydrogen input pipe.

[0021] By adopting the above technical solution, when the pipe clamp of other diameters needs to be replaced and the distance between the drive roller and the hydrogen input pipe needs to be adjusted, the two threaded cylinders at the end of the drive roller can be rotated at the same time to move the threaded cylinders along the studs toward the side closer to or away from the hydrogen input pipe. This causes the two connecting columns to simultaneously drive the rotating roller to move toward the side closer to or away from the hydrogen input pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The flow limiting component can control the flow rate of hydrogen in the hydrogen input pipe. When oxygen flows through the impeller, the impeller can control the flow limiting component to limit the hydrogen flow through the transmission mechanism. This not only achieves the effect of adjusting the hydrogen flow rate according to the oxygen flow rate, but also realizes the automatic adjustment of the hydrogen flow rate.

[0024] 2. The speed of the regulating gear ring can be changed by replacing the pipe clamps of different diameters, thereby changing the flow rate ratio of hydrogen and oxygen.

[0025] 3. The length of the transmission tube can be quickly fixed by rotating the fixing bolt, and the length of the transmission tube can be changed by screwing the fixing bolt into the threaded hole at different positions. By simultaneously rotating the two threaded cylinders at the end of the transmission roller, the two connecting columns can simultaneously drive the rotating roller to move towards or away from the hydrogen input pipe.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8 This application will be described in further detail below.

[0036] An embodiment of this application is: an automatically adjustable hydrogen-oxygen combustion chamber, as described above. Figure 1 , Figure 2 and Figure 3 It includes a cylindrical cavity 1, with an outlet 11 at one end and a hydrogen input pipe 2 fixed and connected to the other end of the cavity 1. An oxygen input pipe 3 is fixed and connected to the hydrogen input pipe 2. (Refer to...) Figure 3 and Figure 4 The oxygen input pipe 3 is equipped with a fan 21 for receiving the power generated by the oxygen in the oxygen input pipe 3. The axis of the fan 21 is set perpendicular to the axis of the oxygen input pipe 3.

[0037] Reference Figure 3 and Figure 5 A transmission mechanism 4 is provided between the hydrogen input pipe 2 and the oxygen input pipe 3 to transmit the force acting on the impeller 21. The transmission mechanism 4 includes a drive assembly 41, which includes a transmission pipe 411. The transmission pipe 411 is coaxially arranged with the impeller 21, and one end of the transmission pipe 411 passes through the side wall of the oxygen input pipe 3 and is fixedly connected to the impeller 21. The other end of the transmission pipe 411 is provided with a gear set 412 for transmitting the power of the transmission pipe 411. The gear set 412 includes a first bevel gear 4121 fixedly connected to the end of the transmission pipe 411. The first bevel gear 4121 is sleeved on the transmission pipe 411 and is coaxially arranged with the transmission pipe 411. A second bevel gear 4122 meshes with one side of the first bevel gear 4121.

[0038] When the wind turbine 21 rotates, it can drive the transmission tube 411 to rotate together, thereby causing the first bevel gear 4121 fixed at the end of the transmission tube 411 to rotate, and finally causing the second bevel gear 4122 meshing with the first bevel gear 4121 to rotate.

[0039] The transmission mechanism 4 also includes a transmission roller 42, which is fixedly connected to and coaxially arranged with the second bevel gear 4122. A pipe clamp 7 is installed on the arc-shaped side wall of the transmission roller 42, and a rack 71 arranged around the outer peripheral wall of the pipe clamp 7 is fixedly connected to the outer peripheral wall of the pipe clamp 7.

[0040] Reference Figure 3 , Figure 4 and Figure 5 A flow-limiting assembly 5 for regulating the flow rate within the hydrogen input pipe 2 is installed on the hydrogen input pipe 2. The flow-limiting assembly 5 includes an adjusting toothed ring 52 rotatably connected to the outer peripheral wall of the hydrogen input pipe 2, and the adjusting toothed ring 52 is arranged around the outer side wall of the hydrogen input pipe 2. A rack 71 meshes with the adjusting toothed ring 52.

[0041] When the second bevel gear 4122 rotates, the transmission roller 42 will rotate simultaneously with the second bevel gear 4122, which in turn causes the pipe clamp 7 installed on the transmission roller 42 to rotate simultaneously with the transmission roller 42, which in turn causes the adjusting gear ring 52 meshed with the rack 71 to rotate.

[0042] The flow limiting component 5 also includes a sealing plate 51 fixedly connected inside the hydrogen input pipe 2, as shown in the figure. Figure 6 Figure 7 and Figure 8 The sealing plate 51 is cylindrical and has an opening 511 for hydrogen flow. A groove 512 is formed on the arc surface of the sealing plate 51. A baffle plate 53 is fixedly connected to the inner arc surface of the adjusting gear ring 52. The curvature of the baffle plate 53 is the same as that of the sealing plate 51. The baffle plate 53 is located inside the hydrogen input pipe 2, and is slidably connected within the groove 512, blocking the opening 511.

[0043] When the adjusting gear ring 52 rotates, the baffle plate 53 rotates along with it, causing the baffle plate 53 to slide within the groove 512, thereby changing the size of the vent 511. To facilitate the reset of the adjusting gear ring 52, a reset assembly 6 is provided. The reset assembly 6 includes a reset block 61 fixed to the end face of the adjusting gear ring 52. A spring 62 is fixedly connected between the reset block 61 and the outer wall of the hydrogen input pipe 2. Thus, when the rack 71 stops applying force to the adjusting gear ring 52, the spring 62 allows the adjusting gear ring 52 to return to its original position, i.e., the position where the baffle plate 53 completely blocks the vent 511.

[0044] Reference Figure 3 and Figure 5The transmission tube 411 includes a first column 4111 and a second column 4112. The second column 4112 is slidably connected inside the first column 4111. A fixing member is provided between the first column 4111 and the second column 4112 to fix the two together. In the figure, the fixing member is a fixing bolt 4113. The fixing bolt 4113 is threadedly connected to the first column 4111. Multiple threaded holes 41121 are provided on the arc-shaped sidewall of the second column 4112, which are equidistant from each other along the axis of the second column 4112. The shank of the fixing bolt 4113 is threadedly connected to one of the threaded holes 41121.

[0045] An adjusting assembly 8 is provided between the drive roller 42 and the hydrogen input pipe 2 to adjust the distance between them. The adjusting assembly 8 includes a connecting post 81 rotatably connected to the end of the drive roller 42, and the connecting post 81 is coaxially arranged with the drive roller 42. A rotating rod 82 is provided at the end of the connecting post 81 away from the drive roller 42. The rotating rod 82 is perpendicular to the connecting post 81, and one end of the rotating rod 82 is fixedly connected to the connecting post 81. A threaded cylinder 83 is rotatably connected to the end of the rotating rod 82 away from the connecting post 81. The threaded cylinder 83 is coaxially arranged with the rotating rod 82. A stud 84 is threadedly connected to the end of the threaded cylinder 83 away from the rotating rod 82. The stud 84 is coaxially arranged with the threaded cylinder 83, and the end of the stud 84 away from the threaded cylinder 83 is fixedly connected to the outer wall of the hydrogen input pipe 2.

[0046] Therefore, when it is necessary to adjust the rate ratio between hydrogen and oxygen, the fixing bolt 4113 can be rotated to remove the fixing state of the fixing bolt 4113 on the first column 4111 and the second column 4112. Then, according to the diameter of the pipe clamp 7, the fixing bolt 4113 is threaded into the appropriate threaded hole 41121. Then, the two threaded cylinders 83 are rotated at the same time to make the threaded cylinders 83 slide along the axial direction of the stud 84, thereby adjusting the position of the transmission roller 42. After replacement, the rack 71 on the pipe clamp 7 meshes with the adjusting gear ring 52.

[0047] The implementation principle of this application embodiment is as follows: Oxygen is introduced into the oxygen inlet pipe 3. When the oxygen flows through the impeller 21, it will drive the impeller 21 to rotate. As a result, the transmission pipe 411, which is coaxially set and fixedly connected to the impeller 21, will rotate together with the impeller 21. Then, under the transmission action of the gear set 412, the force on the impeller 21 is transmitted to the transmission roller 42. This causes the transmission roller 42 to drive the pipe clamp 7 installed on itself to rotate. The rack 71 on the pipe clamp 7 drives the adjusting gear ring 52 to rotate over the force of the spring 62 on the adjusting gear ring 52. Finally, the baffle plate 53 on the adjusting gear ring 52 changes the blocking range of the gas hole 511, thereby making the hydrogen flow rate change in real time with the oxygen flow rate per unit time.

[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
