Abstract
Description
Technical Field
[0001] This utility model relates to the field of air intake distributor technology, and more specifically, to an adjustable air intake distributor for plasma devices. Background Technology
[0002] An air distributor is a key component in fluid (gas or gas-containing mixture) transport systems. Its main function is to evenly and stably distribute the input fluid to multiple branch channels or areas, ensuring that each part receives consistent flow rate, pressure, or velocity. It is widely used in pipeline systems, reactors, combustion devices, and ventilation equipment in fields such as chemical engineering, energy, environmental protection, and aerospace.
[0003] Currently, some existing gas inlet distributors used in plasma devices have an overall structure in which multiple gas distribution pipes are symmetrically distributed on the gas inlet pipe, and multiple gas outlet holes are opened on the gas distribution pipes. Gas enters from the gas inlet pipe and finally exits from the gas outlet holes. However, since the size of the gas outlet holes opened on the gas distribution pipe is fixed, the size of the gas outlet holes cannot be adjusted, and the gas output intensity cannot be controlled. Therefore, it cannot flexibly adapt to different operating conditions. Therefore, we provide an adjustable gas inlet distributor for plasma devices. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable air inlet distributor for plasma devices to solve the problems mentioned in the background art.
[0005] Currently, some existing gas distributors used in plasma devices have an overall structure in which multiple gas distribution pipes are symmetrically distributed on the gas inlet pipe, and multiple gas outlet holes are opened on the gas distribution pipes. Gas enters from the gas inlet pipe and finally sprays out from the gas outlet holes. However, since the size of the gas outlet holes opened on the gas distribution pipe is fixed, the size of the gas outlet holes cannot be adjusted, and the gas output intensity cannot be controlled, thus making it impossible to flexibly adapt to different working conditions.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An adjustable gas inlet distributor for a plasma device includes an inlet pipe, inside which six gas distribution pipes are fixedly connected. The six gas distribution pipes are symmetrically distributed. A first groove is formed inside the gas distribution pipe, and a sliding plate is slidably connected inside the first groove. A first outlet is formed inside the gas distribution pipe, and a second outlet is formed inside the sliding plate. The second outlet cooperates with the first outlet. A rotating rod is rotatably connected inside the inlet pipe. A circular plate is fitted outside the rotating rod and below the sliding plate. The circular plate is fixedly connected to the rotating rod. A second groove is formed inside the circular plate, and a sliding rod is slidably connected inside the second groove. The sliding rod is fixedly connected to the sliding plate.
[0008] Preferably, the outer wall of the slide plate is fitted with the inner wall of the first groove.
[0009] Preferably, a first limiting groove is provided inside the air distribution pipe and on both sides of the corresponding sliding plate, and a limiting plate is slidably connected inside the first limiting groove, and the limiting plate is fixedly connected to the sliding plate.
[0010] Preferably, the circular plate has a second limiting groove inside, there are three second limiting grooves, the three second limiting grooves are symmetrically distributed, and a limiting rod is slidably connected inside the second limiting groove, the limiting rod is fixedly connected to the air intake pipe.
[0011] Preferably, a worm gear is sleeved on the outside of the rotating rod, the worm gear is fixedly connected to the rotating rod, a worm is provided inside the air intake pipe, the worm is meshed with the worm gear, the worm passes through the air intake pipe and extends to the outside of the air intake pipe, the worm is rotatably connected to the air intake pipe, and rotating plates are fixedly connected to both ends of the worm.
[0012] Preferably, a support plate is rotatably connected to the top of the rotating rod, and the support plate is fixedly connected to the air intake pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The rotating plate rotates the worm gear, which in turn drives the rotating rod to rotate via the worm wheel. The rotating rod then drives the circular plate to rotate, and the circular plate presses against the sliding rod through the inner wall of the second sliding groove. This causes the sliding rod to move the slide plate. As the slide plate moves, it can adjust the degree of misalignment between the second and first air outlets, thereby adjusting the size of the air outlet and thus the air output intensity. This allows for adjustment of the air output intensity, making it suitable for different working conditions. The rotating plate and the rotating rod are driven by the worm gear and worm wheel. The worm gear and worm wheel have a self-locking capability, preventing the rotating rod from rotating on its own. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1 to 6 The adjustable air inlet distributor of the plasma device includes an air inlet pipe 1. Six air distribution pipes 2 are fixedly connected inside the air inlet pipe 1, arranged symmetrically. A first sliding groove 3 is formed inside the air distribution pipe 2, and a sliding plate 4 is slidably connected inside the first sliding groove 3. A first air outlet 5 is formed inside the air distribution pipe 2, and a second air outlet 6 is formed inside the sliding plate 4. The second air outlet 6 cooperates with the first air outlet 5, forming an air outlet between the first air outlet 5 and the second air outlet 6. The opening is directly... The air inlet pipe 1 is rotatably connected to a rotating rod 7. A circular plate 8 is fitted outside the rotating rod 7 and below the slide plate 4. The circular plate 8 is fixedly connected to the rotating rod 7. A second sliding groove 9 is opened inside the circular plate 8. A sliding rod 10 is slidably connected inside the second sliding groove 9. The sliding rod 10 is fixedly connected to the slide plate 4. When the circular plate 8 rotates, it can drive the slide plate 4 to move through the second sliding groove 9 and the sliding rod 10, thereby adjusting the position of the second air outlet 6 and the first air outlet 5. The air output intensity is controlled by adjusting the size of the air outlet.
[0024] Furthermore, the outer wall of the slide plate 4 is fitted to the inner wall of the first slide groove 3, and the slide plate 4 and the first slide groove 3 are tightly fitted to ensure sealing.
[0025] Furthermore, a first limiting groove 11 is provided inside the air distribution pipe 2 and on the corresponding two sides of the slide plate 4. A limiting plate 12 is slidably connected inside the first limiting groove 11. The limiting plate 12 is fixedly connected to the slide plate 4. The first limiting groove 11 and the limiting plate 12 limit the slide plate 4 and the first sliding groove 3, so that the slide plate 4 can only slide back and forth in the first sliding groove 3 and will not detach from the first sliding groove 3. At the same time, the first limiting groove 11 and the limiting plate 12 can also further improve the sealing between the slide plate 4 and the first sliding groove 3.
[0026] Furthermore, the circular plate 8 has three second limiting grooves 13 inside, which are symmetrically distributed. A limiting rod 14 is slidably connected inside the second limiting groove 13. The limiting rod 14 is fixedly connected to the air intake pipe 1. The second limiting groove 13 has an arc-shaped structure. The three second limiting grooves 13 are symmetrically distributed about the center of the circular plate 8. The limiting rod 14 has a T-shaped cross-section. The second limiting grooves 13 and the limiting rod 14 can limit the circular plate 8, allowing the circular plate 8 to rotate more smoothly.
[0027] Furthermore, a worm gear 15 is sleeved on the outside of the rotating rod 7, and the worm gear 15 is fixedly connected to the rotating rod 7. A worm 16 is provided inside the intake pipe 1, and the worm 16 is meshed with the worm gear 15. The worm 16 passes through the intake pipe 1 and extends to the outside of the intake pipe 1. The worm 16 is rotatably connected to the intake pipe 1. Rotating plates 17 are fixedly connected to both ends of the worm 16. The worm 16 and the worm gear 15 have a self-locking capability, so that the worm gear 15 cannot rotate on its own when the worm 16 does not rotate, thereby limiting the rotation rod 7 through the worm 16 and the worm gear 15.
[0028] Furthermore, a support plate 18 is rotatably connected to the top of the rotating rod 7. The support plate 18 is fixedly connected to the air intake pipe 1. Since the rotating rod 7 needs to rotate inside the air intake pipe 1, and the rotating rod 7 has a certain length, the support plate 18 is used to support the rotating rod 7 to ensure that the rotating rod 7 can rotate more stably.
[0029] The steps of using this utility model are as follows: When the adjustable air inlet distributor of this plasma device is in use, the worm gear 16 is rotated by the rotating plate 17. The worm gear 16 drives the rotating rod 7 to rotate through the worm wheel 15. The rotating rod 7 drives the circular plate 8 to rotate. The circular plate 8 presses the slide rod 10 through the inner wall of the second slide groove 9, so that the slide rod 10 drives the slide plate 4 to move. When the slide plate 4 moves, it can adjust the degree of misalignment between the second air outlet 6 and the first air outlet 5, thereby adjusting the size of the air outlet and realizing the adjustment of the air outlet intensity. This is beneficial for adapting to different working conditions. Since the rotating plate 17 and the rotating rod 7 are transmitted through the worm gear 16 and the worm wheel 15, and the worm gear 16 and the worm wheel 15 can be self-locked, the stability of the rotating rod 7 is ensured, so that the rotating rod 7 will not rotate on its own.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
