Description

Technical Field

[0001] The present invention relates to the technical field of catalysts, and in particular to a catalyst preparation device. Background Art

[0002] A catalyst is a substance that can change the reaction rate during a chemical reaction, while maintaining its mass and chemical properties before and after the reaction. It accelerates the reaction rate by lowering the activation energy, making the reaction more likely to proceed, without affecting the equilibrium position. Currently, catalysts are widely used in industrial production, environmental protection, energy development, and biomedicine. After being pressed into tablets, catalysts achieve uniform size and shape, high density, and strength, thereby improving their wear resistance and fracture resistance during use, ensuring their full catalytic effect. Furthermore, the formed catalyst particles exhibit good fluidity and stability, facilitating storage and transportation while also reducing wear and contamination during storage and transportation.

[0003] The Chinese patent with the announcement number CN110077027B discloses a powder catalyst tabletting device, which includes a base, a support plate, a first connecting rod, a charging hopper, a discharge pipe, a first bearing seat, a first rotating shaft, a turntable, a handle, a baffle plate, a limit block, a rolling ball, a first spring, a disc, a contact ring and a tabletting mechanism. The left side of the top of the base is fixedly connected to a support plate, and the upper right side of the support plate is fixedly connected to two first connecting rods for supporting. A charging hopper for placing the catalyst is fixedly connected between the right ends of the two first connecting rods. A discharge pipe for discharging the catalyst is connected to the middle of the bottom of the charging hopper. The discharge pipe is connected to the inside of the charging hopper. A first opening for guiding is opened at the lower right side of the discharge pipe. The first opening is provided with a The baffle plate blocked by the chemical agent, the right end of the baffle plate is fixedly connected to the limit block, and a first spring is connected between the upper and lower sides of the left side surface of the limit block and the lower part of the right side surface outside the discharge pipe, and a ball is rotatably provided on the right side of the limit block, and the upper parts of the left and right sides of the discharge pipe are embedded and fixedly connected with the first bearing seats, and a first rotating shaft is provided between the first bearing seats on the left and right sides. The right end of the first rotating shaft is fixedly connected to a disc, and a contact ring matching the ball is fixedly connected to the middle of the left side surface of the disc, and the contact ring contacts the ball. A notch is provided in the middle of the lower part of the left side surface of the contact ring, and a first guide hole is provided on the upper part of the support plate, and the left end of the first rotating shaft is fixedly connected to the turntable through the first guide hole, and a handle is fixedly connected to the eccentric position of the left side of the turntable, and a pressing mechanism is provided between the right side of the disc and the lower right side surface of the support plate.

[0004] During the implementation of the above technical solution, the staff manually turns the handle, and the catalyst in the hopper can fall into the collection hopper through the discharge pipe. As the staff continues to manually turn the handle, the guide sleeve moves downward and drives the second guide rod to move downward, the second guide rod moves downward and drives the first sliding sleeve to move downward, the first sliding sleeve moves downward and drives the pressure plate to move downward. When the pressure plate moves downward, it can squeeze the catalyst in the collection hopper, thereby achieving the tableting of the catalyst. Then, by turning the handle to move the pressure plate upward and reset it, the tableted catalyst can be taken out of the collection hopper. This process requires manual pressing of the catalysts one by one and taking the pressed catalyst tablets out of the collection hopper one by one, which is inconvenient to operate and not conducive to the efficient preparation of catalyst tablets.

[0036] refer to Figure 2-Figure 5 as well as Figure 8, a push rod 40 corresponding to the upper pressure piece 30 is provided on the turntable 20 for sliding in the vertical direction, and the push rod 40 is located below the upper pressure piece 30, and an extrusion cavity 21 cooperating with the upper pressure piece 30 and the push rod 40 is provided on the turntable 20, and a lower sliding block 402 cooperating with the lower sliding hole 202 is provided on the turntable 20 for the push rod 40 to slide. The outer periphery of the push rod 40 has a lower sliding block 402 cooperating with the lower sliding hole 202, and the lower sliding hole 202 is coaxially arranged with the extrusion cavity 21 and the upper sliding hole 201. A lower guide member 12 for driving the push rod 40 to move up and down is fixed on the base 10, and the lower guide member 12 is coaxially arranged with the turntable 20. A guide groove three 121 and a guide groove four 122 are provided on the outer periphery of the lower guide 12. The guide groove three 121 and the guide groove four 122 are connected by a transition groove 123. 121, the lower guide wheel 401 cooperates with the guide groove four 122 and the transition groove 123, the guide groove three 121 and the guide groove four 122 are respectively arranged horizontally, the guide groove three 121 is located above the guide groove four 122, the guide groove two 112 is located above the guide groove four 122, the guide groove three 121 and the transition groove 123 are located below the guide groove one 111, when the lower guide wheel 401 moves in the guide groove four 122, the push rod 40 always remains at the same height, when the lower guide wheel 401 moves in the guide groove three 121, the push rod 40 always remains at the same height, when the lower guide wheel 401 moves from the guide groove four 122 to the guide groove three 121 via the transition groove 123, the push rod 40 will move upward relative to the turntable 20 and push the finished product in the extrusion cavity 21 to the upper end surface of the extrusion cavity 21.

[0037] A rod 2 42 is provided in the push rod 40 through an elastic member 41 that slides. The elastic member 41 is a spring. A sliding groove 403 is provided in the push rod 40 along its axial direction. The outer periphery of the rod 2 42 has a matching block 421 that matches the sliding groove 403. When the matching block 421 stops at the bottom of the sliding groove 403, the upper end surface of the rod 2 42 is flush with the upper end surface of the push rod 40. When the rod 2 42 moves upward relative to the push rod 40, the elastic member 41 will be compressed.

[0038] refer to Figure 2-Figure 5 as well as Figure 9 In this embodiment, the maximum height difference between the guide groove 111 and the guide groove 2 112 is greater than the height difference between the guide groove 3 121 and the guide groove 4 122. An upper top ring 13 and a lower top ring 14 are provided on the base frame 10 for sliding in the vertical direction. The upper top ring 13 and the lower top ring 14 are respectively coaxially arranged with the turntable 20. A driving member 15 for driving the upper top ring 13 to move is provided on the base frame 10. The driving member 15 can be an electric push rod. The upper top ring 13 has an upper rack 131, and the lower top ring 14 has a lower rack 141. A gear 17 meshing with the upper rack 131 is rotatably provided on the base frame 10, and a gear 2 18 meshing with the lower rack 141 is coaxially fixed to one end of the gear 17. Therefore, when the driving member 15 drives the upper top ring 13 to move downward, the lower top ring 14 can move upward at the same time.

[0039] Since the maximum height difference between guide groove one 111 and guide groove two 112 is greater than the height difference between guide groove three 121 and guide groove four 122, in order to ensure that the annular catalyst product is pressed when the lower guide wheel 401 moves in guide groove four 122 and the upper guide wheel 301 moves in guide groove two 112, the upper top ring 13 needs to always keep abutting against the unlocking rod 33 on the upper pressure piece 30 moved into guide groove two 112, and the lower top ring 14 needs to always keep abutting against the rod two 42 on the top rod 40 moved to the upper and lower corresponding positions of guide groove two 112. Therefore, the module of gear one 17 needs to be greater than that of gear two 18, so that when the upper top ring 13 moves downward a larger distance, the lower top ring 14 can only move upward a smaller distance.

[0040] The lower end of the upper top ring 13 has a guide surface 132 that cooperates with the unlocking rod 33, so that when the upper top ring 13 moves downward, the unlocking rod 33 on the upper pressure piece 30 can be smoothly pushed toward the direction close to the limit rod 32; the upper top ring 13 has a guide surface 133 at both ends along its length extension direction that cooperates with the unlocking rod 33, so that when the upper top ring 13 moves downward, the upper pressure piece 30 located on the outer side of the upper top ring 13 enters the inner ring side of the upper top ring 13, the upper top ring 13 can smoothly push the unlocking rod 33 on the upper pressure piece 30 toward the direction close to the limit rod 32; the lower top ring 14 has a guide surface 3 142 at one end along its length extension direction, so that when the rod 2 42 rotates with the push rod 40, the rod 2 42 can smoothly move to the upper end surface of the lower top ring 14 through the guide surface 3 142, so that the rod 2 42 and the lower top ring 14 keep abutting, so that the rod 2 42 extends upward from the upper end surface of the push rod 40.

[0041] In the initial state, the lower end surface of the upper top ring 13 is higher than the highest position of the unlocking rod 33 during the movement of the upper pressure piece 30, and the upper end surface of the lower top ring 14 is lower than the lowest position of the rod 2 42 during the movement of the push rod 40.

[0042] refer to Figure 1-Figure 3 、 Figure 10 as well as Figure 11, a feeding assembly for adding catalyst particles into the extrusion chamber 21 is installed on the base frame 10, and the feeding assembly includes a loading barrel 50 installed on the base frame 10, and a storage barrel 51 for adding catalyst particles into the loading barrel 50 through a pipeline is installed on the base frame 10, and the lower end surface of the loading barrel 50 is in contact with the top surface of the extrusion chamber 21, and the bottom of the loading barrel 50 has a feeding hole 501 for feeding into the extrusion chamber 21, and a plurality of push plates 52 are provided for rotating in the loading barrel 50, and a motor 54 for driving the push plate 52 to rotate is installed on the base frame 10, and the lower end of the push plate 52 has a feeding piece 53 for feeding the catalyst particles in the loading barrel 50 into the extrusion chamber 21. Part 53 is elastic, the direction of rotation of the turntable 20 is the same as the direction of rotation of the push plate 52, and the rotation speed of the push plate 52 is greater than that of the turntable 20. The feeding part 53 has an inclined lower pressure surface 531 on the front side along the rotation direction of the push plate 52. Therefore, during the rotation of the push plate 52, the push plate 52 can push the catalyst particles in the loading barrel 50 into the discharge hole 501. When the extrusion cavity 21 on the turntable 20 moves to below the discharge hole 501, the catalyst particles can fall into the extrusion cavity 21, and the feeding part 53 can force the catalyst particles into the extrusion cavity 21 through the lower pressure surface 531 to ensure that the amount of catalyst particles in each extrusion cavity 21 is relatively uniform.

[0043] A feed pipe 19 is fixedly mounted on the base frame 10 , and a guide plate 191 is provided on the feed pipe 19 for guiding the material ejected from the extrusion chamber 21 by the ejector rod 40 into the feed pipe 19 . The guide plate 191 is located above the top surface of the extrusion chamber 21 .

[0044] Specific working principle: Reference Figures 1-11 When producing the finished columnar catalyst product, in the initial state: the lower end surface of the upper top ring 13 is higher than the highest position of the unlocking rod 33 during the movement of the upper pressure piece 30, and the upper end surface of the lower top ring 14 is lower than the lowest position of the rod 2 42 during the movement of the push rod 40, and the push rod 40 is located in the extrusion chamber 21, and when the lower guide wheel 401 moves in the guide groove four 122, the upper end surface of the push rod 40 is lower than the upper end surface of the extrusion chamber 21, and when the lower guide wheel 401 moves in the guide groove three 121, the upper end surface of the push rod 40 is flush with the upper end surface of the extrusion chamber 21, and when the upper guide wheel 301 moves in the guide groove one 111, the upper pressure piece 30 always remains at the same height, and the lower end of the upper pressure piece 30 is higher than the top of the extrusion chamber 21, and the lower end of the upper pressure piece 30 is higher than the loading barrel 50. In the process of the feeding assembly adding catalyst particles into the extrusion chamber 21, the lower guide wheel 401 is always in the guide groove four 122, and the upper guide wheel 301 is always in the guide groove one 111.

[0045] Control motor 16 and motor 2 54 to operate so that the turntable 20 rotates clockwise (looking from top to bottom along the axis of the turntable 20) and the push plate 52 rotates clockwise. During this process, taking one of the upper pressure pieces 30 and its corresponding upper pressure piece 30 as an example, after the feeding assembly adds the catalyst particles to the extrusion chamber 21, as the turntable 20 rotates, the upper guide wheel 301 will enter the guide groove 2 112, and the upper pressure piece 30 will slide downward and then upward relative to the turntable 20 to achieve the extrusion of the particles in the extrusion chamber 21. When the upper guide wheel 301 leaves the guide groove 2 112 and enters the guide groove 1 111, the lower guide wheel 401 enters the guide groove 3 121 from the guide groove 4 122, thereby ejecting the finished catalyst product pressed in the extrusion chamber 21, and then the guide plate 191 can guide the finished catalyst product into the discharge pipe 19 and discharge it.

[0046] When producing the finished annular catalyst, the driving part 15 is first controlled to move the upper top ring 13 downward and the lower top ring 14 upward, so that the upper top ring 13 can always keep abutting against the unlocking rod 33 on the upper pressure part 30 moved into the guide groove 112, and the lower top ring 14 can always keep abutting against the rod 2 42 on the top rod 40 moved to the upper and lower corresponding guide groove 112. At this time, the unlocking rod 33 entering the inner ring side of the upper top ring 13 can be pushed by the upper top ring 13 toward the direction close to the limit rod 32 so that the end of the limit rod 32 is flush with the side of the matching part 312. When rod 2 42 stops with the upper end face of the lower top ring 14, rod 2 42 can extend upward from the upper end face of the top rod 40 and be flush with the upper end of the extrusion chamber 21. It should be noted that since the lower top ring 14 has a certain length, when the top rod 40 moves to below the discharge hole 501, rod 2 42 in the top rod 40 has already extended upward from the upper end face of the top rod 40.

[0047] Control motor 16 and motor 2 54 to operate so that the turntable 20 rotates clockwise (looking from top to bottom along the axial direction of the turntable 20) and the push plate 52 rotates clockwise. In this process, taking one of the upper pressing pieces 30 and the corresponding upper pressing piece 30 as an example, after the feeding assembly adds catalyst particles to the extrusion chamber 21, as the turntable 20 rotates, the upper guide wheel 301 will enter the guide groove 2 112, and the upper pressing piece 30 will slide downward and then upward relative to the turntable 20. In this process, since the rod 1 31 in the upper pressing piece 30 is unlocked by the unlocking rod 33, the upper pressing piece 30 moves downward and is in contact with the inner surface of the extrusion chamber 21. When the catalyst particles stop, rod 2 42 can push rod 1 31 so that rod 1 31 can move upward relative to the upper pressure piece 30, thereby realizing the extrusion of the catalyst particles. Then, when the upper guide wheel 301 leaves the guide groove 2 112 and enters the guide groove 1 111, the lower guide wheel 401 enters the guide groove 3 121 from the guide groove 4 122, and rod 2 42 and the lower top ring 14 are disengaged from the stop and restored to a state flush with the upper end surface of the push rod 40. The push rod 40 can move upward to eject the finished catalyst product pressed in the extrusion chamber 21, and then the guide plate 191 can guide the finished catalyst product into the discharge pipe 19 and discharge it.
