Description

Technical Field

[0001] This utility model relates to the field of drying device technology, specifically a hydrogen drying device for a hydrogen generator. Background Technology

[0002] A hydrogen generator is a hydrogen production device. A typical hydrogen generator uses the principle of water electrolysis to produce hydrogen. This type of hydrogen generator includes a pure water tank, an electrolytic cell, and a water-gas separator. Its working principle is that the pure water tank located at the top transports water to the electrolytic cell for electrolysis to produce hydrogen. The hydrogen is then collected and used after being dehydrated by the water-gas separator. After long-term use, the internal electrode plates of the hydrogen generator need to be maintained and repaired, and the electrode plates need to be dried after the repair is completed.

[0003] When drying electrode plates in a hydrogen generator's hydrogen drying unit, the electrode plates are often not held securely enough, causing them to wobble during the drying process and negatively impacting the drying effect. Simultaneously, the electrode plates are usually in a fixed position, resulting in uneven contact between the drying airflow and the electrode plates, leading to inconsistent drying levels across different areas. Furthermore, the airflow direction generated by the dryer is relatively fixed, often a continuous direct current jet. This can cause some areas of the electrode plates to be exposed to direct airflow for extended periods, while other areas may receive insufficient airflow, resulting in either localized over-drying or under-drying, making it difficult to guarantee the quality of electrode plate drying. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hydrogen drying device for hydrogen generators. This device solves the problem of uneven contact between the drying airflow and the electrode sheet, which can easily lead to differences in the degree of drying of different parts of the electrode sheet. The airflow jet direction generated by the dryer is relatively fixed, mostly a continuous direct current jet. This can cause local areas of the electrode sheet to be directly exposed to the airflow for a long time, while other areas may not have sufficient contact with the airflow, resulting in local over-drying or insufficient drying, making it difficult to ensure the drying quality of the electrode sheet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen drying device for a hydrogen generator, comprising: a frame and a clamping mechanism, wherein the clamping mechanism is connected to the frame, the clamping mechanism includes a frame, a nut is embedded inside the frame, a threaded rod is threadedly connected inside the nut, and a clamping plate is connected to the outside of the threaded rod through a bearing with a seat.

[0006] When the threaded rod is rotated, the threaded rod will move along the axial direction of the nut because the nut is fixed inside the frame. This will then drive the clamping plate to move closer to or away from the clamped workpiece through the seated bearing, thereby achieving clamping adjustment for workpieces of different sizes. The seated bearing can reduce the radial force on the clamping plate when the threaded rod rotates, ensuring that the clamping plate moves smoothly.

[0007] The frame is externally connected to a rotating component, and the rotating component is externally connected to a cam. When the rotating component rotates, it drives the cam to rotate synchronously. The eccentric structure of the cam can cooperate with other components during rotation to assist the clamping plate in achieving more precise clamping action and enhance clamping stability. A drying device is provided at the upper end of the frame, and the drying device includes a dryer.

[0008] The dryer is slidably connected to the frame, and a linkage is rotatably connected to the upper end of the dryer. A transmission component is rotatably connected to the other end of the linkage, and a guide component is connected to the outside of the transmission component. The guide component is slidably connected to the frame.

[0009] A return component is connected between the guide component and the frame. When the guide component slides along the frame, it drives the linkage component to rotate through the transmission component, thereby driving the dryer to slide along the frame and adjust the position of the dryer to meet different drying needs. The return component pulls the guide component back to its original position when it is not subjected to external force, thereby driving the dryer back to its initial position. A drive mechanism is provided on the left side of the clamping mechanism.

[0010] Preferably, the drive mechanism includes gears connected to rotating components. Three sets of gears mesh with each other. A drive component is connected to the left side of the frame. The output end of the drive component is connected to the central gear. When the drive component is working, it drives the central gear to rotate. Since the three sets of gears mesh with each other, it can synchronously drive the other two sets of gears to rotate, thereby driving the rotating component connected to them to move synchronously, ensuring that the clamping rhythm of multiple clamping mechanisms is consistent, and improving the synchronicity and stability of clamping.

[0011] Preferably, the frame is externally connected to a platform, and a reinforcing rib is provided between the platform and the frame. The platform is connected to the drive component. The platform provides a stable mounting base for the drive component, and the reinforcing rib enhances the structural strength of the connection between the platform and the frame. This can effectively disperse the vibration and stress generated when the drive component is working, prevent the platform from deforming, and ensure the long-term stable operation of the drive component.

[0012] Preferably, the top of the frame is evenly provided with track grooves, and track blocks are slidably connected inside the track grooves. The track blocks are slidably connected to the track grooves, and the cooperation between the track blocks and the track grooves provides guidance for the sliding of the dryer, ensuring that the dryer moves along a fixed trajectory, avoiding deviation, and improving the accuracy of the dryer's position adjustment. The inner cavity of the frame is evenly provided with sliding grooves, which are slidably connected to guide members and return members. The sliding grooves limit and guide the sliding of the guide members, ensuring that the guide members move smoothly, while providing installation space for the return members, ensuring that the return members can stably perform their reset function.

[0013] Preferably, the inner cavity of the frame is provided with a rubber pad. The rubber pad can increase the friction between the clamping plate and the clamped part, preventing the clamped part from slipping during drying or clamping. At the same time, the elastic properties of the rubber can buffer the clamping force and avoid damage to the surface of the clamped part. A spherical bearing is connected between the rotating part and the frame. The spherical bearing can adapt to the small angular displacement that may occur during the rotation of the rotating part, reduce the friction and wear between the rotating part and the frame, and ensure that the rotating part rotates flexibly and smoothly.

[0014] Preferably, the dryer is equipped with a heater and a fan in its inner cavity, and a nozzle is connected to the top of the dryer. The heater can heat the air to a suitable temperature, and the fan blows the heated dry air through the nozzle to the hydrogen-related components being dried, thereby accelerating the evaporation of moisture on the surface or inside of the components and improving the drying efficiency. The nozzle can concentrate the airflow and enhance the targeted drying effect.

[0015] Compared with the prior art, this utility model provides a hydrogen drying device for a hydrogen generator, which has the following beneficial effects:

[0016] This hydrogen generator uses a hydrogen drying device. Through the cooperation of a threaded rod and a clamping plate, it stably holds the electrode sheet, ensuring its stable position during drying and preventing vibration from affecting the drying effect. The drive mechanism rotates the rotating component and frame, allowing the electrode sheet to rotate during drying. Combined with the drying airflow generated by the dryer, this ensures more even contact between all parts of the electrode sheet and the airflow, improving drying uniformity. Simultaneously, the rotation of the rotating component drives the cam to move the guide component. Through the cooperation of the transmission and linkage components, this causes the dryer to move, changing the direction of the airflow injection. This prevents continuous direct airflow onto the electrode sheet, reducing localized over-drying or under-drying, further optimizing the drying effect and ensuring the quality of the dried electrode sheet.

[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] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A hydrogen drying device for a hydrogen generator includes: a frame 1 and a clamping mechanism 3. The clamping mechanism 3 is connected to the frame 1. The clamping mechanism 3 includes a frame 31. A nut 38 is embedded inside the frame 31. A threaded rod 37 is threadedly connected inside the nut 38. A clamping plate 36 is connected to the outside of the threaded rod 37 through a bearing seat.

[0024] When the threaded rod 37 is rotated, since the nut 38 is fixed inside the frame 31, the threaded rod 37 will move along the axial direction of the nut 38, and then drive the clamping plate 36 to move closer to or away from the clamped workpiece through the seated bearing, so as to realize the clamping adjustment of workpieces of different sizes. The seated bearing can reduce the radial force on the clamping plate 36 when the threaded rod 37 rotates, ensuring that the clamping plate 36 moves smoothly.

[0025] Please see Figure 3 and Figure 4 The frame 31 is externally connected to a rotating component 32, and the rotating component 32 is externally connected to a cam 33. When the rotating component 32 rotates, it drives the cam 33 to rotate synchronously. The eccentric structure of the cam 33 can cooperate with other components during rotation to assist the clamping plate 36 in achieving more precise clamping action and enhancing clamping stability. A drying device 2 is provided at the upper end of the frame 1. The drying device 2 includes a dryer 21.

[0026] The dryer 21 is slidably connected to the frame 1. The upper end of the dryer 21 is rotatably connected to the linkage 22, and the other end of the linkage 22 is rotatably connected to the transmission component 23. The transmission component 23 is externally connected to the guide component 24, and the guide component 24 is slidably connected to the frame 1.

[0027] A return member 25 is connected between the guide member 24 and the frame 1. When the guide member 24 slides along the frame 1, it drives the linkage member 22 to rotate through the transmission member 23, thereby driving the dryer 21 to slide along the frame 1, so as to adjust the position of the dryer 21 to adapt to different drying needs. The return member 25 pulls the guide member 24 to reset when it is not subjected to external force, thereby driving the dryer 21 back to the initial position. A drive mechanism 4 is provided on the left side of the clamping mechanism 3.

[0028] The drive mechanism 4 includes a gear 41, which is connected to the rotating component 32. The three sets of gears 41 mesh with each other. The left side of the frame 1 is connected to the drive component 42. The output end of the drive component 42 is connected to the gear 41 in the middle. When the drive component 42 is working, it drives the gear 41 in the middle to rotate. Since the three sets of gears 41 mesh with each other, it can drive the other two sets of gears 41 to rotate synchronously, thereby driving the rotating component 32 connected to it to move synchronously, ensuring that the clamping rhythm of the multiple clamping mechanisms 3 is consistent, and improving the synchronicity and stability of clamping.

[0029] The frame 1 is externally connected to a platform 43, and a reinforcing rib is provided between the platform 43 and the frame 1. The platform 43 is connected to the drive component 42. The platform 43 provides a stable mounting base for the drive component 42, and the reinforcing rib enhances the structural strength of the connection between the platform 43 and the frame 1. It can effectively disperse the vibration and stress generated when the drive component 42 is working, prevent the platform 43 from deforming, and ensure the long-term stable operation of the drive component 42.

[0030] The top of the frame 1 is evenly provided with track grooves 11. Track blocks 26 are slidably connected inside the track grooves 11. The cooperation between the track blocks 26 and the track grooves 11 provides guidance for the sliding of the dryer 21, ensuring that the dryer 21 moves along a fixed trajectory, avoiding deviation, and improving the accuracy of the position adjustment of the dryer 21. The inner cavity of the frame 1 is evenly provided with sliding grooves. The sliding grooves are slidably connected to the guide members 24 and the return members 25. The sliding grooves limit and guide the sliding of the guide members 24, ensuring that the guide members 24 move smoothly. At the same time, they provide installation space for the return members 25, ensuring that the return members 25 can stably perform the reset function.

[0031] The inner cavity of the frame 31 is provided with a rubber pad 35. The rubber pad 35 can increase the friction between the clamping plate 36 and the clamped part, preventing the clamped part from slipping during drying or clamping. At the same time, the elastic properties of the rubber can buffer the clamping force and avoid damage to the surface of the clamped part. A spherical bearing 34 is connected between the rotating part 32 and the frame 1. The spherical bearing 34 can adapt to the small angular displacement that the rotating part 32 may produce during rotation, reduce the friction and wear between the rotating part 32 and the frame 1, and ensure that the rotating part 32 rotates flexibly and smoothly.

[0032] The dryer 21 has a heater and a fan inside, and a nozzle is connected to the top of the dryer 21. The heater can heat the air to a suitable temperature, and the fan blows the heated dry air through the nozzle to the hydrogen-related components being dried, accelerating the evaporation of moisture on the surface or inside of the components and improving the drying efficiency. The nozzle setting can concentrate the airflow and enhance the targeted drying effect.

[0033] In this design, the electrode sheet is placed inside the frame 31. The rotating threaded rod 37 drives the clamping plate 36 to fix the electrode sheet. The starting drive component 42 drives the gear 41 to rotate, which in turn drives the rotating component 32 to rotate, thereby driving the frame 31 to rotate. The dryer 21 is started to generate a drying airflow to dry the electrode sheet. At the same time, the rotation of the rotating component 32 drives the cam 33 to drive the guide component 24 to move, which in turn drives the transmission component 23 and the linkage component 22 to drive the dryer 21 to move. This avoids the airflow generated by the dryer 21 continuously spraying the electrode sheet with direct current for drying.
