Abstract

This invention discloses a preparation system and method for catalytic hydrogen production materials, relating to the field of hydrogen production material preparation technology. The system includes a base, and further comprises: a support disk rotatably mounted inside the base; a bending disk fixedly mounted above the support disk; and a rotating column rotatably mounted at the center of the support disk. Several disturbance components are installed on the arc-shaped circumference of the rotating column.

In this invention, during ball milling in a three-dimensional ball mill, the centrifugal force, combined with the support disk and bending disk, allows the material to be thrown towards the center on the bending disk. Then, the rotating column and its disturbance components further refine the material, and qualified material is collected simultaneously during the continuous grinding process.

Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production material preparation, and in particular to a preparation system and method of a catalytic hydrogen production material. Background Art

[0002] The global energy demand is growing rapidly, and renewable energy will play an important role. Among them, hydrogen energy is widely regarded as the clean energy with the greatest development potential in the 21st century. In the process of hydrogen production, the use of catalysts greatly promotes the efficiency of hydrogen production, and ceramic catalysts are commonly used;

[0003] In the manufacture of ceramic catalysts, it is usually necessary to carry out systematic steps such as crushing, ball milling, and sintering of raw materials. The ball milling process requires the use of a ball mill to make the material particles reach the required size. Some existing ball mills usually rotate horizontally, so that the ball mill body moves downward with the rolling of the machine and impacts and crushes the material during the movement. However, simply using its own weight to roll and impact and crush, a large amount of material is piled up during the grinding process. The ball mill body needs to roll many times during the ball milling process before grinding some of the materials gathered in the middle, which makes the grinding efficiency low and the overall grinding time long. In addition, the qualified materials in the grinding process cannot be collected and need to be collected after the entire grinding is completed. Summary of the invention

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1-11 A system for preparing catalytic hydrogen production materials includes a base 1, and further includes: a carrier plate 31, which is rotatably mounted inside the base 1; a bending plate 32, which is fixedly mounted above the carrier plate 31; a rotating column 41, which is rotatably mounted at the center of the carrier plate 31, and a disturbance component 44 is installed on the arc circumference of the rotating column 41;

[0037] When the carrier plate 31 rotates rapidly, the materials and grinding bodies on the surface of the carrier plate 31 are dispersed outwards by centrifugal force, and when they fly out of the carrier plate 31, they fly toward the rotating column 41 through the inwardly inclined bending plate 32. At this time, the rotating rotating column 41 drives the disrupting component 44 to disrupt and strike the materials and the grinding bodies, so that the materials are broken into smaller pieces.

[0038] The overall height of the bending plate 32 can be reduced, and the inclination angle of the bending plate 32 can be tilted upward, so that the materials and ball mills thrown out by the centrifugal force of the supporting plate 31 can pass through the bending plate 32 more easily.

[0039] In another embodiment of the present invention: a servo motor 51 is fixedly mounted on the bottom end of the base 1, a gear 52 is fixedly mounted on the output end of the servo motor 51, a circular ring is fixedly mounted on the bottom end of the carrier plate 31, and tooth grooves are provided on the inner wall of the circular ring and the bottom end of the rotating column 41;

[0040] The servo motor 51 is started, and the servo motor 51 drives the gear 52 to rotate, and then the gear 52 drives the gear ring 53 and the rotating column 41 to rotate. At this time, the rotation of the gear ring 53 drives the carrier plate 31 to rotate. At this time, the material and the ball mill placed on the carrier plate 31 will slide outward due to the centrifugal force generated when the carrier plate 31 rotates. Since the inner wall of the peripheral side of the carrier plate 31 is inclined upward, at this time, the inertia of sliding outward causes it to move onto the bending plate 32, and at this time, the bending plate 32 is inclined toward the direction of the rotating column 41. At this time, the material and the ball mill moved to the bending plate 32 by inertia The ball mill will fly out of the bending disk 32, but at this time the flying direction is toward the rotating column 41. Therefore, the rotating rotating column 41 will also drive the disturbance component 44 thereon to hit the flying material and the ball mill. As the material contacts the disturbance component 44, it will be crushed, making the material smaller. When the ball mill contacts the disturbance component 44, the ball mill will be hit and fly back. At this time, the hit ball mill will collide with the ball mill that just flew out of the bending disk 32, thereby hitting and grinding the material between the two again, making the overall grinding effect better.

[0041] In another embodiment of the present invention: a movable groove 411 is formed on the rotating column 41, and the disrupting component 44 is disposed in the movable groove 411;

[0042] The disrupting assembly 44 includes a fixed plate 442 fixedly installed in the movable groove 411, two long rods 441 are rotatably installed on the fixed plate 442, and a movable plate 444 is rotatably installed on one end of the two long rods 441 away from the fixed plate 442;

[0043] The two long rods 441, the fixed plate 442 and the movable plate 444 form a parallelogram. When the rotating column 41 rotates, the parallelogram-shaped disrupting component 44 will rotate with one end of the fixed plate 442 as the center. As the parallelogram-shaped disrupting component 44 rotates, the gap size between the two long rods 441 will change. Fig. 9 As shown, in the process of rotating from the top to the bottom, the gap size between the two long rods 441 will first increase and then decrease. When the disrupting component 44 rotates with the rotating column 41, when the parallelogram-shaped disrupting component 44 first rotates to a rectangular state, the gap size between the two long rods 441 is the largest. The gap of this size is not enough for the ball mill to enter, but some materials can enter the gap. As the parallelogram-shaped disrupting component 44 continues to move, as the gap decreases, and the two long rods 441 move relative to each other, the materials in the gap will be squeezed and crushed by the two long rods 441, thereby further improving the grinding effect.

[0044] In another embodiment of the present invention: friction blocks 443 are rotatably mounted on the ends of the two long rods 441 that are close to each other;

[0045] The material between the two long rods 441 is squeezed and ground by the long rods 441 themselves, and is also squeezed and crushed by the friction block 443 to be ground;

[0046] Furthermore, a groove is provided on the friction block 443; the size of the groove is set to be consistent with the size required for material grinding. When the material enters the gap between the two long rods 441, as the friction block 443 squeezes and rubs the material, the groove on the friction block 443 will also crush and squeeze the material, so that the material is cut by the groove, and the material of qualified size will enter the groove. At the same time, as the rotating column 41 rotates, the contact between the ball mill and the long rod 441 will vibrate the long rod 441, so that the qualified material in the groove will fall out again.

[0047] In another embodiment of the present invention: a bottom rod 48 is fixedly mounted on the inner wall of the base 1, a vertical rod 47 is fixedly mounted on the bottom rod 48, a disk 46 is fixedly mounted on the top of the vertical rod 47, and a connected arc groove 461 and a flat groove 462 are formed on the arc surface of the disk 46;

[0048] A round frame 45 is vertically slidably mounted on the top of the rotating column 41, a connecting rod 43 is rotatably mounted inside the rotating column 41, a rotating rod 42 is fixedly mounted on the top of the connecting rod 43, a spiral groove 421 is provided on the rotating rod 42, an outer insert 452 is fixedly mounted on the outer wall of the round frame 45, an inner insert 451 matching the spiral groove 421 is fixedly mounted on the inner wall of the round frame 45, and one of the same set of long rods 441 is fixedly mounted on the connecting rod 43;

[0049] The outer insert 452 is inserted into the flat groove 462 and the arc groove 461, and the disc 46 is kept in a fixed and stationary state by the vertical rod 47 and the bottom rod 48. When the rotating column 41 rotates, the rotating column 41 will drive the circular frame 45 to rotate around the circular disc 46. As the circular frame 45 moves, the outer insert 452 thereon will also move in the flat groove 462 and the arc groove 461. The arc groove 461 is arranged in a wave shape. Therefore, when the outer insert 452 moves in the arc groove 461, the circular frame 45 will move up and down. At this time, the inner insert 451 will move up and down in the spiral groove 421. At this time, the spiral groove 421 on the rotating rod 42 will be squeezed by the inner insert 451 to drive the rotating rod 42 to rotate. As the rotating rod 42 rotates, it will drive a long rod 441 in a disturbance component to rotate through the connecting rod 43. As one of the long rods 441 rotates, it will drive the entire disturbance component to rotate through the parallelogram arrangement.

[0050] The flat groove 462 occupies three quarters of the arc surface of the disk 46 , and the arc groove 461 occupies the remaining quarter.

[0051] In another embodiment of the present invention: a fixing bar 61 is fixedly mounted on the bottom end of the disc 46, a friction disc 62 is rotatably mounted on the bottom end of the fixing bar 61, a rotating ring 63 is rotatably mounted on the vertical rod 47, and a fan blade 64 is fixedly mounted on the rotating ring 63;

[0052] The rotating column 41 is provided with a through slot 412 which is connected to the movable slot 411, and a filter plate 49 is fixedly mounted on the inner wall of the through slot 412;

[0053] Among them, the friction disc 62, the rotating ring 63 and the inner wall of the rotating column 41 are in contact with each other, so when the rotating column 41 rotates, the rotating column 41 will drive the friction disc 62 to rotate, and the rotating ring 63 will be driven to rotate through the friction disc 62. As the rotating ring 63 rotates, the fan blades 64 thereon will also rotate accordingly. As the fan blades 64 rotate, a downward wind flow will be generated. At this time, the material entering the interior of the rotating column 41 through the filter plate 49 will be blown to the bottom for collection.

[0054] In another embodiment of the present invention: the filter holes on the filter plate 49 are arranged to be tilted downward toward the inside of the rotating column 41, and a long groove 413 is provided on the rotating column 41;

[0055] The forward and reverse rotation of the carrier plate 31 can cause the material and the ball mill to move outwards due to the centrifugal force. Figure 4 When the carrier plate 31 rotates clockwise, the rotating column 41 will reverse counterclockwise, and when the outer insert 452 is located in the flat groove 462, it will be in the following state: Figure 8 In the state shown, the rotating column 41 rotates counterclockwise, but the long rod 441 forms an acute angle with the rotating column 41 in the counterclockwise rotation direction. When the long rod 441 rotates counterclockwise with the rotating column 41, part of the material will be driven by the acute angle formed by the long rod 441 and move synchronously. At the same time, the long rod 441 and the long groove 413 fit together. At this time, the size of the long groove 413 is consistent with the size of the qualified material. When the rotating column 41 keeps rotating counterclockwise, the fan blades 64 inside it will rotate to blow the airflow downward. At this time, since the filter holes are tilted downward inward, the setting direction of the filter holes is along the flow direction of the airflow, so that the airflow will not directly enter the filter holes. At the same time, the air pressure at the position where the airflow is close to the filter plate 49 is reduced. The air pressure at the movable groove 411 is high, so that the air near the movable groove 411 flows toward the filter plate 49. At this time, the material near the movable groove 411 will enter the inside of the rotating column 41 from the filter hole to be collected. At the same time, due to the counterclockwise rotation of the rotating column 41, the acute angle space formed between the long rod 441 and the rotating column 41 will squeeze the air through the inclination angle of the long rod 441, so that the air enters the movable groove 411 and the through groove 412 through the long groove 413, and enters the rotating column 41 through the filter hole, so that the material of the size at the acute angle of the long rod 441 enters the through groove 412 through the long groove 413 and enters the rotating column 41 through the filter hole to be collected.

[0056] When the rotating column 41 rotates clockwise, the outer insert 452 is located in the flat groove 462, and the long rod 441 still maintains Figure 8 In the state shown, the angle of the long rod 441 along the rotation direction of the rotating column 41 forms an obtuse angle with the rotating column 41. At this time, the material will not be driven by the obtuse angle formed by the long rod 441 and the rotating column 41 to move. At this time, the long rod 441 will face the material and the ball mill in a wider range, and the surface of the long rod 441 will impact the material and the ball mill, so that more ball mills are knocked outward, and more materials are crushed by the ball mills hitting each other, and the grinding effect is better.

[0057] At the same time, when the rotating column 41 rotates clockwise, the fan blades 64 inside it rotate in the opposite direction, and air will be blown upwards. At this time, the filter holes are arranged to face the airflow, and part of the upward airflow will move along the filter holes toward the movable groove 411. At this time, the materials stuck in some filter holes will be blown out, so that the filter holes remain in an effective vacant state to avoid blockage affecting the filtering effect.

[0058] Before ball milling, the rotating column 41 is kept rotating clockwise. In this state, the rotating column 41 drives the disrupting component 44 to collide with the flying ball mill and the material more easily, so that the ball mill can be repeatedly ball milled in the air, and the material can be crushed when directly hitting the material, so that the grinding is more efficient and the grinding effect is improved. When the grinding reaches a certain degree, the rotating column 41 is rotated counterclockwise. At this time, the rotating column 41 rotating counterclockwise will collect the material while grinding, so that the qualified material can be collected while the ball milling is being carried out;

[0059] When the outer insert 452 passes through the arc groove 461, the outer insert 452 is squeezed by the inner wall of the arc groove 461 and moves up and down, thereby driving the circular frame 45 to move up and down, so that the disrupting component 44 rotates. During the counterclockwise rotation of the rotating column 41 and the rotation of the disrupting component 44, the rotation of the long rod 441 will cause the long groove 413 to be covered and opened from time to time. When the long rod 441 just starts to leave the long groove 413, the long rod 441 and the rotating column 41 are still at an acute angle. At this time, the long groove 413 is not covered but airflow still passes through, so that the stuck logistics in the long groove 413 can be blown out and cleared, and when the long rod 441 contacts the long groove 413, a certain vibration effect is generated, which can loosen the stuck state of the material and the long groove 413, thereby facilitating its falling off.

[0060] In another embodiment of the present invention: a plurality of connecting strips 453 are fixedly mounted on the bottom end of the round frame 45;

[0061] The round frame 45 slides vertically with the rotating column 41 via a plurality of connecting bars 453 .

[0062] In another embodiment of the present invention: a top guard plate 2 is fixedly mounted on the top of the base 1;

[0063] The top guard plate 2 is installed on the periphery of the bearing plate 31 and the bending plate 32 and surrounds the bearing plate 31 and the bending plate 32 . The top guard plate 2 is higher than the bending plate 32 . The top guard plate 2 can block some of the ball mills and materials that fly out.
