Description

Technical Field

[0001] This invention relates to the technical field of a hydrogen storage tank filling equipment, specifically a filling device for hydrogen storage materials in a physical hydrogen storage tank. Background Technology

[0002] Hydrogen storage is of great significance for the safe application of hydrogen, and high-density hydrogen storage plays a vital role in the development of hydrogen energy. Currently, there are many ways to store hydrogen, including high-pressure gaseous hydrogen storage, cryogenic hydrogen storage, metal hydride hydrogen storage, and physical adsorption hydrogen storage. Among them, physical adsorption hydrogen storage technology has the advantages of high safety and good reversibility, making it an important research direction for the large-scale and commercial efficient utilization of hydrogen, and thus has a very good application prospect.

[0003] Physical adsorption hydrogen storage primarily involves storing hydrogen in molecular form within a storage material through physical adsorption. Therefore, the packing density of the storage material within the physical adsorption hydrogen storage tank significantly impacts the hydrogen storage capacity. It is essential to fill the tank with as much storage material as possible. However, this method suffers from several drawbacks: uneven packing, low density, and slow packing speed. Furthermore, physical adsorption hydrogen storage materials are often porous, resulting in significant gaps between them. Additionally, the pressure generated during hydrogen storage causes the material itself to be subjected to pressure, leading to fine friction. If the packing is not tight, the large gaps between the materials can easily cause damage and reduce the storage capacity. To address this issue, it is crucial to ensure uniform packing and minimize excessively large gaps between the hydrogen storage materials.

[0004] Therefore, in order to avoid the above-mentioned technical problems, it is indeed necessary to provide a filling device for hydrogen storage materials in a physical hydrogen storage tank. Summary of the Invention

[0005] (I) Technical problem to be solved by the present invention The purpose of this invention is to provide a method that can automatically and accurately fill hydrogen storage materials while reducing the breakage rate of the hydrogen storage materials and increasing the filling amount, so as to solve the problems of uncontrollable breakage of hydrogen storage materials, slow filling speed, and low filling amount in the filling of hydrogen storage tanks.

[0006] (II) Technical Solution of the Invention This invention provides a filling device for hydrogen storage material in a physical hydrogen storage tank. The filling device comprises a shell, a hopper, and a funnel. The hopper contains a baffle, a support plate, and a horizontal plate. A rotating shaft is located in the middle of the baffle and controlled by a drive motor mounted on the outer wall of the shell. The support plate is installed below the baffle, and a partition is provided between the support plates. A pressure sensor is installed below the support plate. A slide rail is provided on the inner wall of the shell. The horizontal plate is fixed to a rotating mechanism and fixed to the shell. The rotating mechanism contains a first telescopic rod and a second telescopic rod, with an openable cover plate installed at the end of the second telescopic rod.

[0007] Preferably, the baffle has four rotation axes and three parallel plates.

[0008] Preferably, the width of the parallel plate is greater than the width of the spacer between the support plates, and the parallel plate does not rotate with the rotation axis.

[0009] Preferably, a sliding rod is provided on the partition between the support plates.

[0010] Preferably, the outer surface of the slide bar is triangularly inclined.

[0011] Preferably, the rotating mechanism is controlled by a drive motor on the outer wall of the housing and is fixedly connected to the first telescopic rod.

[0012] Preferably, metal arcs are fixed on both sides of the end of the first telescopic rod.

[0013] Preferably, the metal arc is tangent to the outer side of the second telescopic rod, and when the second telescopic rod is extended, the outer wall of the openable cover plate is tangent to the inner side of the metal arc.

[0014] Preferably, the width of the hinged cover is slightly smaller than the inner diameter of the funnel opening.

[0015] The present invention has the following beneficial effects: 1. This invention uses a baffle and a parallel plate on the baffle. A drive motor drives each rotating shaft to rotate, causing the baffle to rotate and tilt. This allows the hydrogen storage material to slowly enter the support plate below the baffle. A pressure sensor on the lower side of the support plate feeds back an electrical signal. When the set amount is reached, the baffle resets. This method accurately measures the quality of the hydrogen storage material while ensuring safety and stability during the filling process.

[0016] 2. This invention utilizes a rotating mechanism mounted on a horizontal plate to drive the first and second telescopic rods to rotate. Simultaneously, the first telescopic rod controls the position of the opening / closing cover. When open, the tangential action of the metal arc at the end of the first telescopic rod on the opening / closing cover allows for multi-angle opening and closing. When the second telescopic rod is not extended, the opening / closing cover is fully closed, and the hydrogen storage material is directly discharged through the outlet. As the angle of the opening / closing cover changes, the rotation of the rotating mechanism causes the hydrogen storage material to be evenly dispersed throughout the tank by the centrifugal force generated by the rotation, resulting in a uniform lateral distribution. When the opening / closing cover is fully open, the first telescopic rod can be used to gently press the hydrogen storage material, ensuring a uniform longitudinal distribution. This significantly increases the amount of hydrogen storage material filling the tank and makes the filling more compact, reducing gaps between the hydrogen storage materials and preventing breakage caused by compression when hydrogen enters the tank under pressure.

[0017] 3. The present invention is equipped with multiple funnels. When the device is running, the rotation shaft can be adjusted by the drive motor and multiple hydrogen storage tanks can be filled with hydrogen storage material simultaneously through the support plate, so as to achieve automated and efficient filling.

Detailed Implementation

[0020] The following will be combined with the appendix Figures 1 to 6This invention will be described in detail, and the technical solutions in the embodiments of this invention will be fully and clearly described. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the specific embodiments shown in the accompanying drawings.

[0022] See appendix Figure 1-6 This invention discloses a filling device for hydrogen storage materials in a physical hydrogen storage tank. The filling device comprises a housing 1, a hopper 2, and a funnel. The hopper contains a baffle 3, a support plate 8, and a horizontal plate 13. A rotating shaft 4 is located in the middle of the baffle 3 and is controlled by a drive motor 9 mounted on the outer wall of the housing 1. The support plate 8 is installed below the baffle 3, and a partition 6 is provided between the support plates 8. A pressure sensor 10 is installed below the support plate 8. The housing 1 is provided with a slide rail 11. The horizontal plate 13 is fixedly connected to and fixed to the housing 1 by a rotating mechanism 12. A first... A telescopic rod 14 and a second telescopic rod 15 are provided. The end of the second telescopic rod 15 is equipped with an openable cover plate 16. The baffle 3 is driven by the drive motor 9, which drives the rotating shaft 4 to rotate and tilt the baffle. The hydrogen storage material will fall onto the support plate 8, which can accurately measure the mass of the hydrogen storage material. The support plate 8 can tilt along the slide rail 11 on the shell 1 to pour the hydrogen storage material into the outlet. The horizontal plate 13 provides a way for the installation of the rotating mechanism 12 and the support plate 8. The rotating mechanism 12 is also driven by the drive motor 9 to rotate, so that the centrifugal force generated by the rotation of the hydrogen storage material is evenly distributed in the hydrogen storage tank.

[0023] The rotating shaft 4 of the baffle 3 is divided into four parts, and three parallel plates 5 are provided on the baffle 3. The rotation of the rotating shaft is controlled by the drive motor, so that the hydrogen storage material in the hopper falls onto the support plate, and the pressure sensor at the bottom of the support plate provides feedback on the weight information of the hydrogen storage material.

[0024] The width of the parallel plate 5 is greater than the width of the spacer 6 between the support plate 8, and the parallel plate 5 does not rotate with the rotating shaft 4; when the baffle is tilted, the hydrogen storage material begins to fall on the support plate 8, so that the hydrogen storage material falls on the corresponding support plate 8, which can accurately measure the discharge amount of each funnel, and at the same time facilitates the discharge of some funnels while the other funnels stop discharging.

[0025] A sliding rod 7 is provided on the partition 6 between the support plates 8; the hydrogen storage material falling on the support plate 8 is pushed back and forth by the sliding rod, so that the hydrogen storage material is evenly distributed on the support plate, so that the pressure sensor 10 below the support plate 8 can more accurately control the weight information, so as to correctly feedback the weight information of the hydrogen storage material and accurately control the filling amount of the hydrogen storage material.

[0026] The outer surface of the slide bar 7 is triangularly inclined; it smoothly pushes the hydrogen storage material without damaging it, and at the same time makes the hydrogen storage material evenly spread on the support plate.

[0027] The rotating mechanism 12 is controlled by the drive motor 9 on the outer wall of the housing 1 and is fixedly connected to the first telescopic rod 14; so that the rotating mechanism can drive the first telescopic rod to rotate while rotating, thereby realizing the extension and retraction of the first telescopic rod while rotating.

[0028] Metal arcs 17 are fixed on both sides of the end of the first telescopic rod 14; these are used to control the angle of the opening and closing cover plate 16 when the second telescopic rod is extended or retracted.

[0029] The metal arc 17 is tangent to the outer side of the second telescopic rod 15. When the second telescopic rod 15 is extended, the outer side of the opening and closing cover 16 is tangent to the inner side of the metal arc 17. The extension and retraction of the second telescopic rod 15 can drive the opening and closing of the opening and closing cover 16. The opening and closing cover 16 can be controlled at multiple angles, so that when the hydrogen storage material is filled from the funnel outlet, the opening and closing of the cover at multiple angles can achieve uniform filling of the hydrogen storage tank.

[0030] The width of the hinged cover 16 is slightly smaller than the inner diameter of the funnel opening; the hinged cover 16 can be installed inside the funnel and will not damage the device when it is opened or closed.

[0031] The hinged cover plate 16 has multiple pores with a diameter of 20mm-100mm. This prevents the hydrogen storage material from cracking due to compression when it is pressed, keeps the hydrogen storage material uniform in the longitudinal direction, and reduces the gaps between the hydrogen storage materials, thus ensuring the uniformity and high density of the hydrogen storage material during filling.

[0032] Working principle: First, hydrogen storage material is added from the top of the silo, allowing it to be stored inside. Simultaneously, the opening of the hydrogen storage tank is connected to the opening of the funnel. After the support plate is installed, the drive motor rotates the shaft, causing the baffle to tilt. The hydrogen storage material falls onto the support plate through the gap between the baffle and the inner wall of the shell. At this time, a sliding rod pushes the hydrogen storage material back and forth, ensuring it is evenly spread on the support plate. A pressure sensor below the support plate feeds a signal back to the control console. When the set value is reached, the sliding rod and baffle reset. The support plate is then tilted by an external traction device along the slide rail inside the shell, causing the hydrogen storage material to fall into the funnel opening.

[0033] Simultaneously, the first telescopic rod brings the opening and closing cover to the bottom of the hydrogen storage tank. At the same time, the second telescopic rod extends, allowing the opening and closing cover to open at multiple angles because its back is tangent to the inner side of the metal arc. At this time, the drive motor drives the rotating mechanism to rotate, and the opening and closing cover also rotates accordingly. The hydrogen storage material falls into the hydrogen storage tank from above. The hydrogen storage material will be evenly dispersed in the tank due to the centrifugal force generated by the rotation of the rotating mechanism. When the opening and closing cover is fully open, the hydrogen storage material can be gently pressed by the first telescopic rod, so that the hydrogen storage material is evenly distributed in the longitudinal direction, which can greatly improve the filling amount of hydrogen storage material inside the hydrogen storage tank. After the hydrogen storage material has descended, the hinged cover is fully opened to 0 degrees. The first telescopic rod then gently presses down on the hydrogen storage material while the rotating mechanism continues to rotate slowly. This ensures that the hydrogen storage material is evenly pressed down by the hinged cover and distributed longitudinally, which greatly improves the filling amount of hydrogen storage material inside the hydrogen storage tank. The above steps are then repeated until the hydrogen storage tank is completely filled. The first and second telescopic rods then retract, with the second telescopic rod retracting first and the first telescopic rod extending and retracting last.
