Description

Technical Field

[0001] The present invention relates to the technical field of ignition and combustion stabilization equipment, and in particular to a flexibly switchable plasma ignition and combustion stabilization equipment and a control method thereof. Background Art

[0002] Plasma ignition and combustion stabilization equipment is a device that uses plasma technology to achieve fuel ignition and stable combustion. It is widely used in high temperature and high pressure environments such as industrial boilers, gas turbines, internal combustion engines, and combustion furnaces. High-frequency power supplies excite gas through electric fields to generate plasma, thereby providing sufficient energy to ignite the fuel. Existing ignition and combustion stabilization equipment still has some shortcomings.

[0003] For example, the invention patent with the publication number CN114935147A discloses an automatic electric ignition device and a flame combustion device for injection molding products, including a frame; a photoelectric switch, which is arranged on the frame, including a laser emitter and a laser receiver; a shielding rod, which is arranged between the laser emitter and the laser receiver, and an ignition head, which is arranged on the shielding rod and is connected to the laser receiver electrical signal; the flame combustion device includes the above-mentioned automatic electric ignition device, an energy storage tank arranged on the frame, a combustion head, a pipe connecting the energy storage tank and the combustion head, and a valve arranged on the pipe, and the ignition head and the combustion head are together. The signal of the photoelectric switch is controlled by lifting and lowering the shielding rod, thereby controlling the ignition and closing of the ignition head.

[0015] A control method for a flexible switching plasma ignition and stabilization combustion device comprises the following steps:

[0016] S1: The chassis and the bracket are used to support the whole device. The fuel is transported to the solenoid valve through the connecting pipe. When the solenoid valve is opened, the gas fuel is ignited by the igniter to perform combustion. When the second connecting shaft and the second supporting plate are not installed on the outside of the pipe sleeve, the flame can be gathered to improve the combustion efficiency. The electric push rod is extended to move the round table pressing block upward. The side of the round table pressing block will abut the solenoid valve. The solenoid valve drives the pipe sleeve to rotate on the first supporting plate through the first connecting shaft. The top of the pipe sleeve gathers toward the central axis of the device, thereby gathering the flame for centralized combustion.

[0017] S2: When it is necessary to disperse the flame for burning in a wider range, shorten the electric push rod to move the round table pressing block downward. When the round table pressing block moves downward, the leaf spring in the original bent state will be reset, so that the first connecting shafts at various locations on the first support plate are restored to the initial state;

[0018] S3: When the electric push rod is extended to the top, the pressing component can cooperate with the trigger component to automatically close the solenoid valve, thereby limiting the degree of flame accumulation;

[0019] S4: When the second connecting shaft and the second supporting plate are installed on the outside of the pipe sleeve, the second supporting plate is moved so that the second supporting plate moves while maintaining parallelism with the first supporting plate, thereby changing the angle of the pipe sleeve. After the angle of the pipe sleeve changes, the second connecting shaft rotates in the second supporting plate, and the first connecting shaft rotates in the first supporting plate, thereby changing the flame angle.

[0020] The working principle and beneficial effects of the present invention are:

[0021] 1. The device is provided with an electric push rod, a truncated cone pressure block, a first connecting shaft and a first connecting plate. When the second connecting shaft and the second supporting plate are not installed, the truncated cone pressure block moves upward and presses the solenoid valves at various locations by extending the electric push rod, so that the solenoid valves expand outward. During the outward expansion of the solenoid valves, the pipe sleeve can drive the first connecting shaft to rotate on the first connecting plate, so that the tops of the pipe sleeves gather toward the middle at the same time, thereby realizing the function of gathering flames. The leaf spring can subsequently automatically reset the solenoid valve and the igniter, so that the device can change the degree of flame gathering by adjusting the height of the truncated cone pressure block, thereby solving the problem that the existing ignition and stabilization device cannot adjust the degree of flame gathering.

[0022] 2. The device is provided with a detachable second connecting shaft and a second supporting plate. When the second connecting shaft and the second supporting plate are not installed, the frustum pressing block on the device can change the degree of flame concentration. When the second connecting shaft and the second supporting plate are installed on the outside of the pipe sleeve, the position of the second supporting plate can be adjusted to synchronously adjust the angles of multiple pipe sleeves, so that the device can change the flame angle. The device can change the adjustment mode of the device by removing or installing the second connecting shaft and the second supporting plate, which solves the problem that the existing ignition and stabilization device cannot flexibly switch between adjusting the flame angle and adjusting the flame concentration. The device has the advantage of greater adaptability.

[0023] 3. By setting up the first support assembly and the second support assembly, the device can conveniently adjust the flame angle. By adjusting the front and rear position and left and right position of the second support plate, during the adjustment process, the first connecting block slides on the first connecting rod, and the second connecting block slides on the second connecting rod to adapt to the height change of the second support plate during the movement. The first motor on the driving assembly drives the first screw to rotate to change the front and rear position of the second support plate. The second motor drives the second screw to rotate to change the left and right position of the second support plate, so that the device can remain fixed after the angle of the pipe sleeve is adjusted, thereby ensuring that the flame angle remains stable after adjustment.

[0024] 4. Through the set trigger assembly and pressing assembly, when the device adjusts the degree of flame concentration, after the truncated table pressure block moves to the top, the switch button can be pressed through the second connecting rod to automatically close the solenoid valve, thereby automatically shutting off the flame after the flame gathers to the middle position, avoiding high-temperature burn-through and ensuring the safety of the device when in use.

DETAILED DESCRIPTION

[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1-Figure 12As shown, this embodiment proposes a flexibly switchable plasma ignition and stabilization combustion device, including a chassis 1, a bracket 2 is welded on the chassis 1, a first support plate 3 is fixedly connected to the bracket 2, an electric push rod 4 is installed in the middle of the chassis 1, a round table pressure block 5 is fixedly connected to the top of the electric push rod 4, a trigger component 6 is installed on the round table pressure block 5, a pressing component 7 is installed on the first support plate 3, a leaf spring 9 is installed on the chassis 1, a connecting pipe 8 is fixedly arranged on the leaf spring 9, an electromagnetic valve 10 is connected to the top of the connecting pipe 8 and the leaf spring 9, and an ignition The igniter 11 is provided with a tube sleeve 12 fixedly disposed above the igniter 11. When adjusting the degree of flame concentration, the device can extend the electric push rod 4 to move the truncated cone pressing block 5 upward. The truncated cone pressing block 5 will resist the solenoid valve 10, so that the solenoid valve 10 can expand outward and the top of the tube sleeve 12 can be gathered toward the middle to adjust the degree of flame concentration. The tube sleeve 12 is sequentially installed with a first connecting shaft 13 and a second connecting shaft 14 from bottom to top. The second supporting plate 15 is fitted on the outside of the second connecting shaft 14. The first connecting shaft 13 and the first supporting plate 3 are rotatably connected. When the second supporting plate 15 and the second connecting shaft 14 are not installed, the degree of flame concentration can be changed. When the second connecting shaft 14 and the second supporting plate 15 are installed on the outside of the tube sleeve 12, the angles of multiple tube sleeves 12 can be changed at the same time by adjusting the front and rear positions and the left and right positions of the second supporting plate 15, thereby changing the flame angle. The device can prevent excessive flame accumulation. Since the more the cone pressing block 5 moves upward, the higher the flame accumulation degree is, when the cone pressing block 5 moves up to a certain position, the pressing component 7 can act on the trigger component 6 to realize the function of automatically closing the solenoid valve 10, thereby automatically shutting down the combustion function when the flame is excessively accumulated, thereby ensuring the safety of the device when in use.

[0042] Example 2

[0043] like Figure 1-Figure 12 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a flexibly switchable plasma ignition and stabilization combustion device.

[0044] In this embodiment, the trigger component 6 includes a groove 603 opened in the middle of the truncated cone pressing block 5, and a switch button 601 is fixedly arranged in the groove 603. The bottom of the switch button 601 is connected to a wire 602, and the wire 602 is connected to the solenoid valve 10. After pressing the switch button 601, the open or closed state of the solenoid valve 10 can be changed. If the flame of the device is subsequently over-concentrated, the switch button 601 can be automatically pressed to stop the flame combustion.

[0045] In this embodiment, the pressing assembly 7 includes a ball shaft 701 rotatably installed in the middle of the first support plate 3, a through hole 702 is opened in the ball shaft 701, and a first connecting rod 703 and a second connecting rod 706 are slidably installed on the upper and lower sides of the through hole 702 respectively, a sliding groove 704 is opened on the first connecting rod 703, a guide rod 705 is slidably installed in the sliding groove 704, and the bottom of the guide rod 705 is connected to the second connecting rod 706, and a spring 707 is installed between the first connecting rod 703 and the second connecting rod 706. When the angle of the first connecting rod 703 changes, the ball shaft 701 will rotate on the first support plate 3. When the second connecting rod 706 abuts against the contact object, the guide rod 705 can slide inside the sliding groove 704, the spring 707 is gradually compressed, and the pressure of the spring 707 gradually increases, so as to automatically shut down the fire later.

[0046] In this embodiment, a third connecting shaft 16 is fixedly provided on the top of the first connecting rod 703, and a rotating groove 17 for the third connecting shaft 16 to rotate is opened in the second support plate 15. The second support plate 15 and the first support plate 3 are parallel to each other. The third connecting shaft 16 can resist the inner wall of the rotating groove 17 on the second support plate 15, so that the second support plate 15 can maintain a suitable height after installation. When the second support plate 15 moves, the third connecting shaft 16 can rotate in the rotating groove 17 to facilitate the subsequent stable adjustment of the flame angle.

[0047] In this embodiment, the first connecting shaft 13 is evenly distributed along the circumference of the first support disk 3, and the pipe sleeve 12 forms a rotating structure between the first connecting shaft 13 and the first support disk 3. The central axes of the pipe sleeve 12, the first connecting shaft 13 and the second connecting shaft 14 are all on the same straight line. The second connecting shaft 14 and the pipe sleeve 12 are slidably connected. Through the rotating structure on the device, the top of the pipe sleeve 12 can diffuse outward at the same time, which is convenient for adjusting the degree of flame concentration. The slidably installed second connecting shaft 14 can be removed from the pipe sleeve 12 to facilitate the subsequent switching of the adjustment mode of the device. After the second connecting shaft 14 is removed, the degree of flame concentration can be adjusted. After the second connecting shaft 14 is installed, the angles of multiple pipe sleeves 12 can be adjusted synchronously, thereby changing the combustion angle.

[0048] In this embodiment, the first support assembly 18 and the second support assembly 19 are respectively installed on both sides of the second support plate 15, and a slide plate 20 is connected between the first support assembly 18 and the second support assembly 19. A connecting seat 22 is fixedly provided at the bottom of the chassis 1, and the slide plate 20 is slidably installed in the connecting seat 22. A driving assembly 21 is installed on the second support assembly 19 and the slide plate 20. The first support assembly 18 and the second support assembly 19 can support the second support plate 15. The slide plate 20 and the driving assembly 21 are used to adjust the front and rear position or left and right position of the second support plate 15, so as to accurately adjust the flame angle subsequently.

Fig.11 As shown, when the slide plate 20 slides to the right, the second support plate 15 moves to the right, and drives the first connecting plate 1804 and the first sliding rod 1805 to pull the first rotating ring 1803 to the right through the first supporting block 1806. The first rotating ring 1803 can drive the first connecting block 1801 to move through the first movable rod 1802. The first connecting block 1801 can pull the second support plate 15 during the movement, so that the second support plate 15 moves. The height of the second support plate 15 will change during the movement, and the first connecting block 1801 will slide on the outside of the first movable rod 1802 to adapt to the height change of the second support plate 15.

[0050] In this embodiment, the second support assembly 19 includes a second connecting block 1901 fixedly connected to the second support plate 15, the second connecting block 1901 and the first connecting block 1801 are symmetrically distributed on both sides of the second support plate 15, a second movable rod 1902 is provided through the first connecting block 1801, a second rotating ring 1903 is rotatably installed on the top of the second movable rod 1902, a second connecting plate 1904 is fixedly provided on the second rotating ring 1903, a second sliding rod 1905 is fixedly connected to the bottom of the second connecting plate 1904, and the slide plate 20 is away from the first A second support block 1906 is fixedly connected to one side of a support block 1806, and a second slide bar 1905 is slidably connected to the second support block 1906. When the second support plate 15 moves to the left, the height of the second support plate 15 will change, and the second connecting block 1901 will slide on the outside of the second movable rod 1902. At the same time, the second connecting plate 1904, the second slide bar 1905 and the second support block 1906 will move synchronously with the second rotating ring 1903, thereby changing the position of the second support plate 15, and then making the flame face the left or right.

[0051] In this embodiment, the driving component 21 includes a first motor 2101 fixedly connected to the second support block 1906, and a first screw 2102 is fixedly arranged on the output shaft of the first motor 2101, and the first screw 2102 and the second slide bar 1905 are threadedly connected. A second motor 2103 is arranged on the left side of the skateboard 20, and a second screw 2104 is installed on the output shaft of the second motor 2103, and the second screw 2104 and the skateboard 20 are threadedly connected. The first motor 2101 drives the first screw 2102 to rotate, and drives the second slide bar 1905 to slide inside the second support block 1906, thereby changing the front and rear position of the second support block 1906, which is convenient for the subsequent adjustment of the front and rear direction of the flame. The second motor 2103 is fixed on the ground, and the second motor 2103 drives the second screw 2104 to rotate, driving the skateboard 20 to slide left and right, so as to facilitate the subsequent fixing work after the flame direction is adjusted.

[0052] Specifically, the present invention is a flexible switching plasma ignition and stabilization device and a control method thereof. First, Figure 1-Figure 7 As shown, the bottom of the connecting pipe 8 needs to be connected to the gas fuel first, the chassis 1 and the bracket 2 are used to support the entire device, and the gas fuel is transported to the solenoid valve 10 through the connecting pipe 8. When the solenoid valve 10 is opened, the gas fuel is ignited by the igniter 11 to perform combustion. Figure 4 and Figure 5 As shown, when the second connecting shaft 14 and the second support plate 15 are not installed on the outside of the pipe sleeve 12, the flame can be gathered to improve the combustion efficiency. The electric push rod 4 is extended to move the truncated cone pressing block 5 upward. The side of the truncated cone pressing block 5 will abut the electromagnetic valve 10. The electromagnetic valve 10 drives the pipe sleeve 12 to rotate on the first support plate 3 through the first connecting shaft 13. The top of the pipe sleeve 12 gathers toward the central axis position of the device, thereby gathering the flame for centralized combustion. When it is necessary to disperse the flame for a wider range of combustion, the electric push rod 4 is shortened to move the truncated cone pressing block 5 downward. When the truncated cone pressing block 5 moves downward, it will reset the leaf spring 9 that was originally in a bent state, so that the first connecting shafts 13 at various locations on the first support plate 3 are restored to Figure 4 The initial state of .

[0053] like Figure 5-Figure 10As shown, when the electric push rod 4 is extended to the top, the pressing assembly 7 can cooperate with the trigger assembly 6 to automatically close the solenoid valve 10, thereby limiting the degree of flame gathering. When the top of the pipe sleeve 12 gathers toward the middle, the angle of the first connecting rod 703 changes, and the ball shaft 701 rotates on the first support plate 3. When the second connecting rod 706 abuts against the switch button 601 in the groove 603, the guide rod 705 can slide inside the slide groove 704, and the spring 707 is gradually compressed. The pressure of the spring 707 gradually increases to facilitate the subsequent pressing of the switch button 601. The wire 602 of the switch button 601 is connected to the solenoid valve 10, so that the device can automatically turn off the fire when the flame is over-concentrated. When the second connecting shaft 14 and the second supporting plate 15 are installed on the outside of the pipe sleeve 12, the third connecting shaft 16 above the first connecting rod 703 is placed in the rotating groove 17, and then the second supporting plate 15 is moved. The second supporting plate 15 moves forward and backward or left and right while maintaining parallelism with the first supporting plate 3, thereby synchronously changing the installation angles of multiple pipe sleeves 12. After the angle of the pipe sleeve 12 changes, the second connecting shaft 14 rotates in the second supporting plate 15, and the first connecting shaft 13 rotates in the first supporting plate 3, thereby changing the flame angle.

[0054] like Fig.11 and Fig.12 As shown, the first support assembly 18, the second support assembly 19 and the driving assembly 21 on the device are used to adjust and fix the left-right position and the front-back position of the second support plate 15. When the slide plate 20 slides to the right, the second support plate 15 moves to the right, and the first connecting plate 1804 and the first slide bar 1805 are driven to pull the first rotating ring 1803 to the right through the first support block 1806. The first rotating ring 1803 can drive the first connecting block 1801 to move through the first movable bar 1802. The first connecting block 1801 can pull the second support plate 15 during the movement, so that the second support plate 15 moves. The second support plate 15 changes its own height when moving, and the first connecting block 1801 slides on the outside of the first movable bar 1802 to adapt to the height change of the second support plate 15. At the same time, the second connecting block 1901 will slide on the outside of the second movable rod 1902, and the second connecting plate 1904, the second sliding rod 1905 and the second supporting block 1906 will move synchronously with the second rotating ring 1903, thereby changing the position of the second supporting plate 15, and then making the flame face left or right. The first motor 2101 drives the first screw rod 2102 to rotate, driving the second sliding rod 1905 to slide inside the second supporting block 1906, thereby changing the front and rear position of the second supporting block 1906, facilitating the subsequent adjustment of the front and rear direction of the flame. The second motor 2103 is fixed on the ground, and the second motor 2103 drives the second screw rod 2104 to rotate, driving the slide plate 20 to slide left and right, so as to fix the flame after the subsequent adjustment.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

10. A control method for a flexibly switchable plasma ignition and stabilization device, using the flexibly switchable plasma ignition and stabilization device according to claim 1, characterized in that: The steps include: S1: The chassis (1) and the bracket (2) are used to support the device as a whole. The fuel is transported to the solenoid valve (10) through the connecting pipe (8). When the solenoid valve (10) is opened, the gas fuel is ignited by the igniter (11) to perform combustion. When the second connecting shaft (14) and the second supporting plate (15) are not installed on the outside of the pipe sleeve (12), the flame can be gathered to improve the combustion efficiency. The electric push rod (4) is extended to move the round table pressing block (5) upward. The side of the round table pressing block (5) will abut against the solenoid valve (10). The solenoid valve (10) drives the pipe sleeve (12) to rotate on the first supporting plate (3) through the first connecting shaft (13). The top of the pipe sleeve (12) gathers toward the central axis of the device, thereby gathering the flame for centralized combustion. S2: When it is necessary to disperse the flame for burning in a wider range, the electric push rod (4) is shortened to move the truncated cone pressing block (5) downward. When the truncated cone pressing block (5) moves downward, the leaf spring (9) in the original bent state is reset, thereby restoring the first connecting shafts (13) at various locations on the first support plate (3) to their initial state; S3: When the electric push rod (4) is extended to the uppermost position, the pressing assembly (7) can cooperate with the trigger assembly (6) to automatically close the solenoid valve (10), thereby limiting the degree of flame accumulation; S4: When the second connecting shaft (14) and the second supporting plate (15) are installed on the outside of the pipe sleeve (12), the second supporting plate (15) is moved so that the second supporting plate (15) moves while being kept parallel to the first supporting plate (3), thereby changing the angle of the pipe sleeve (12). After the angle of the pipe sleeve (12) changes, the second connecting shaft (14) rotates in the second supporting plate (15), and the first connecting shaft (13) rotates in the first supporting plate (3), thereby changing the flame angle.
