Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage equipment technology, and in particular to a device for filling hydrogen storage material inside a petal tube. Background Technology

[0002] Currently, the application of hydrogen energy is becoming increasingly widespread, but there are certain difficulties in storage and transportation. Hydrogen storage alloys can absorb or release hydrogen under certain conditions, and their hydrogen storage density is much higher than that of gaseous hydrogen storage. Therefore, solid-state hydrogen storage using hydrogen storage alloys has attracted much attention. When hydrogen storage alloys absorb hydrogen, they release it, absorbing a large amount of heat, reaching about 30 kJ / mol. The heat transfer efficiency of the device becomes the most important factor affecting the rate of hydrogen absorption (release) reaction. However, the thermal conductivity of hydrogen storage alloys is very low, about 0.5 W / (mK), which limits the heat transfer capacity of hydrogen storage devices. Traditional hydrogen storage tubes are usually hollow cylindrical structures. This structure has a small contact area with the external cooling water, and the heat exchange capacity with the external cooling water is also weak.

[0003] Based on the above problems, this utility model proposes a device for filling hydrogen storage material inside a petal tube. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hydrogen storage material filling device inside a petal tube. The hydrogen storage tube has a spiral structure with a petal-shaped cross-section, which can increase the contact area with the external cooling water under the same cross-sectional area and improve the flow heat exchange capacity of the external cooling water.

[0005] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows:

[0006] This utility model discloses a hydrogen storage material filling device for a petal-shaped tube, comprising a hydrogen storage tube, a filling mechanism, and a conveying mechanism. The cross-section of the hydrogen storage tube is a cross-shaped structure composed of four petal-shaped parts connected in sequence. The hydrogen storage tube is a hollow spiral structure with an open top that rotates clockwise around its cross-sectional center. The filling mechanism includes a storage hopper and a filling head. The storage hopper has a funnel-shaped structure, and its bottom is connected to the top of the filling head used for filling the hydrogen storage tube. The hydrogen storage tube is conveyed to the bottom of the filling mechanism by the conveying mechanism.

[0007] The petal portion includes two parallel longitudinal segments and a semi-circular ring segment. The outer ends of the two longitudinal segments are respectively connected to the end of the semi-circular ring segment, and the inner ends of the two longitudinal segments are respectively connected to the inner ends of the longitudinal segments of the adjacent petal portion through arc segments.

[0009] The conveying mechanism includes a first conveyor belt, a turntable, a second conveyor belt, a drive motor, a base plate, and guard plates. The turntable is circular with several fixed grooves arranged in a ring around its edge. Each fixed groove is semi-circular, with a radius equal to the maximum cross-sectional radius of the hydrogen storage tube. The drive motor is located below the turntable, and its output shaft is axially fixedly connected to the turntable. The inner end of the first conveyor belt contacts the left outer wall of the turntable. First conveyor belt guard plates are located on both sides of the first conveyor belt, with the distance between the two guard plates equal to the maximum outer diameter of the hydrogen storage tube. The first conveyor belt guard plate on one side... The inner end of the first conveyor belt has an inlet, the width of which is half the maximum outer diameter of the hydrogen storage tube. The outer end of the inlet is connected to one end of a semi-circular protective plate. The gap between the inner wall of the protective plate and the outer wall of the turntable is equal to half the maximum outer diameter of the hydrogen storage tube. The bottom of the protective plate is connected to a semi-circular base plate for supporting the hydrogen storage tube. The inner end of the second conveyor belt contacts the right outer wall of the turntable. The top two sides of the second conveyor belt are provided with second conveyor belt protective plates. The inner end of the right second conveyor belt protective plate is tangent to the right end of the protective plate. The distance between the two second conveyor belt protective plates is equal to the maximum outer diameter of the hydrogen storage tube.

[0010] Above the turntable, there is also a compaction mechanism and a secondary filling mechanism. The outer wall of the turntable is provided with a first fixing groove, a second fixing groove and a third fixing groove in sequence. The first fixing groove is located on the right side of the inlet. The filling mechanism is located directly above the first fixing groove. The compaction mechanism and the secondary filling mechanism are respectively located directly above the second fixing groove and the third fixing groove. The secondary filling mechanism has the same structure as the filling mechanism.

[0011] The compaction mechanism includes a compaction rod and a cylinder. The outer diameter of the compaction rod is equal to the inner diameter of the hydrogen storage tube, and the bottom end of the compaction rod has a hemispherical structure. The top end of the compaction rod is connected to the output end of the cylinder, driving it to move in the vertical direction.

Detailed Implementation

[0020] The present invention will be further described below:

[0021] Please see Figure 1-4 ,

[0022] This utility model discloses a hydrogen storage material filling device for a petal-shaped tube, including a hydrogen storage tube 1, a filling mechanism 2, and a conveying mechanism 3. The cross-section of the hydrogen storage tube 1 is a cross-shaped structure composed of four petal-shaped parts 11 connected in sequence. The hydrogen storage tube 1 is a hollow spiral structure with an open top that rotates clockwise around its cross-sectional center. The spiral structure with a petal-shaped cross-section of the hydrogen storage tube 1 can increase the contact area with the external cooling water under the same cross-sectional area and improve the flow heat exchange capacity of the external cooling water.

[0023] Furthermore, the petal portion 11 includes two parallel longitudinal segments 111 and a semi-circular ring segment 112. The outer ends of the two longitudinal segments 111 are respectively connected to the end of the semi-circular ring segment 112. The inner ends of the two longitudinal segments 111 are respectively connected to the inner ends of the longitudinal segments 111 of the adjacent petal portion 11 through arc segments 113. Adjacent petal portions 11 are connected by arc segments 113. The outer ends of the two longitudinal segments 111 are connected by semi-circular ring segments 112. This allows the hydrogen storage material to move smoothly downward along the inner cavity of the hydrogen storage tube 1 during filling.

[0024] Furthermore, the filling mechanism 2 includes a storage bin 21 and a filling head 22. The storage bin 21 has a funnel-shaped structure, and its bottom is connected to the top of the filling head 22 used for filling the hydrogen storage tube 1. The hydrogen storage tube 1 is conveyed to the bottom of the filling mechanism 2 through the conveying mechanism 3.

[0025] Furthermore, the outer diameter of the filling head 22 is equal to the inner diameter of the hydrogen storage tube 1; the top center of the storage bin 21 is connected to the piston rod end of a cylinder that can move vertically, and the piston rod of the cylinder can drive the storage bin 21 to move vertically, and the filling head 22 can be inserted into the top of the inner cavity of the hydrogen storage tube 1 to avoid waste of hydrogen storage material during the filling process.

[0026] Furthermore, the conveying mechanism 3 includes a first conveyor belt 31, a turntable 32, a second conveyor belt 33, a drive motor 34, a base plate 35, and a guard plate 36. The turntable 32 has a circular structure, and its edge has a plurality of fixed grooves 37 arranged in a ring. The fixed grooves 37 have a semi-circular structure, and their radii are equal to the maximum cross-sectional radius of the hydrogen storage tube 1. The drive motor 34 is located below the turntable 32, and the output shaft of the drive motor 34 is fixedly connected to the axial direction of the turntable 32. The inner end of the first conveyor belt 31 contacts the left outer wall of the turntable 32. First conveyor belt guard plates 38 are provided on both sides of the first conveyor belt 31. The distance between the two first conveyor belt guard plates 38 is equal to the maximum outer diameter of the hydrogen storage tube 1. The inner end of one of the first conveyor belt guard plates 38 is provided with an inlet 39. The width of the inlet 39 is half the maximum outer diameter of the hydrogen storage tube 1. The outer end of the inlet 39 is connected to one end of the semi-circular protective plate 36. The gap between the inner wall of the protective plate 36 and the outer wall of the turntable 32 is equal to half the maximum outer diameter of the hydrogen storage tube 1. The bottom of the protective plate 36 is connected to a semi-circular bottom plate 35 for supporting the hydrogen storage tube 1. The inner end of the second conveyor belt 33 contacts the right outer wall of the turntable 32. The top two sides of the second conveyor belt 33 are provided with second conveyor belt protective plates 40. The inner end of the right second conveyor belt protective plate 40 is tangent to the right end of the protective plate 36. The distance between the two second conveyor belt protective plates 40 is equal to the maximum outer diameter of the hydrogen storage tube 1. The conveying mechanism 3 makes the hydrogen storage process of the hydrogen storage tube 1 simpler and more convenient, improves production efficiency, and reduces labor intensity.

[0027] Furthermore, a compaction mechanism 4 and a secondary filling mechanism 5 are provided above the turntable 32. The outer wall of the turntable 32 is provided with a first fixing groove 371, a second fixing groove 372, and a third fixing groove 373 in sequence. The first fixing groove 371 is located to the right of the inlet 39. The filling mechanism 2 is located directly above the first fixing groove 371. The compaction mechanism 4 and the secondary filling mechanism 5 are respectively located directly above the second fixing groove 372 and the third fixing groove 373. The secondary filling mechanism 5 has the same structure as the filling mechanism 2. After the hydrogen storage tube 1 is filled with hydrogen storage alloy in the first fixing groove 371 by the filling mechanism 2, it is rotated by the turntable 3 to the position of the second fixing groove 372 and compacted by the compaction mechanism 4. After compaction, a space for filling is created inside. At this time, the turntable 3 rotates it to the position of the third fixing groove 373 and performs secondary filling by the secondary filling mechanism 5, which can improve the utilization rate of the storage space of the hydrogen storage tube 1.

[0028] Furthermore, the compaction mechanism 4 includes a compaction rod 41 and a cylinder. The outer diameter of the compaction rod 41 is equal to the inner diameter of the hydrogen storage tube 1, which facilitates the compaction rod 41 to be inserted into the inner ring of the hydrogen storage tube 1 for compaction. The bottom end of the compaction rod 41 has a hemispherical structure, which makes it easier for the compaction rod 41 to be inserted into the hydrogen storage tube 1. The top end of the compaction rod 41 is connected to the output end of the cylinder, driving it to move in the vertical direction.

[0029] Working process: An empty hydrogen storage tube 1 is conveyed to the inner end of the first conveyor belt 31, waiting for the previous hydrogen storage tube 1 to be filled. After the previous hydrogen storage tube 1 is filled, the turntable 32 rotates, causing the fixed groove 37 to connect with the end of the first conveyor belt 31. The first conveyor belt 31 moves the hydrogen storage tube 1 to the fixed groove 37. At this time, half of the hydrogen storage tube 1 is inside the fixed groove 37 and half is outside the fixed groove 37, just enough to pass through the inlet 39, which has a width equal to half the outer diameter of the hydrogen storage tube 1. It can also rotate clockwise with the turntable 37 through the fixed groove 37. During the rotation, the guard plate 36 can limit its outer side, and the bottom plate 35 can support its bottom. When it rotates to the first fixed groove 371, the cylinder above the filling mechanism 2 drives it to descend. The filling head 22 of the filling mechanism 2 is inserted into the hydrogen storage tube 1 to fill the hydrogen storage material. After filling, the turntable 32 rotates clockwise to the position of the second fixed groove 372. The compaction rod 41 of the compaction mechanism 4 is driven by the cylinder to descend and insert into the hydrogen storage tube 1 to compact the hydrogen storage material inside. After compaction, the turntable 32 continues to rotate clockwise to the position of the third fixed groove 373. The cylinder above the secondary filling mechanism 5 drives it to descend, so that the filling head of the secondary filling mechanism 5 is inserted into the hydrogen storage tube 1 to fill the hydrogen storage material. After filling, the turntable 32 continues to rotate clockwise. When it rotates to the second conveyor belt 33, due to the guiding effect of the second conveyor belt guard plate 40 on the left, the hydrogen storage tube 1 can be transported to the next process through the second conveyor belt 33.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
