[0002] Catalytic materials are the foundation and core of modern chemical processes. As a functional material, the performance of catalysts is influenced by the interaction of many factors, such as process conditions, preparation methods, and multi-component formulations. The discovery and application of catalytic materials, from the laboratory stage to practical use, usually takes a long time, generally 10 to 20 years. The high-throughput concept originated from combinatorial chemistry and has been widely applied in many fields, such as pharmaceuticals, materials, and catalysis. In the field of catalysis, the application of combinatorial technology, that is, to achieve the batch synthesis of catalysts, and then to conduct high-throughput screening of candidate catalysts, and gradually optimize the composition and synthesis conditions of catalysts through cyclic experiments, can greatly accelerate the catalyst development process.
[0003] Existing catalysts are not suitable for handling the carrier during multi-channel screening when performing activity screening. Since the carrier needs to be completely placed inside the container, another set of catalysts needs to be screened after screening. Therefore, the handling process is cumbersome and does not improve efficiency. At the same time, it is not possible to change the carrier for different channels, which means that only catalysts within a specified number of channels can be screened. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. The present invention, through the setting of the picking and placing mechanism, can realize the lifting operation of the carrier holding the catalyst, so as to improve the operation efficiency when changing the same number of carriers or different numbers of carriers. It is not only simple and convenient to operate, but also improves the required adaptability and screening efficiency. The motor works to make the first gear and the second gear rotate.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] This invention provides a parallel high-throughput catalyst activity characterization screening device. The parallel high-throughput catalyst activity characterization screening device includes a base 1 and a temperature detection sensor 6. The inner cavity of the base 1 is provided with a picking and placing mechanism 2 for easy picking and placing of materials. The top of the base 1 is provided with a sealing mechanism 3 for easy sealing. The top of the base 1 is provided with a support mechanism 4. The inside of the support mechanism 4 is provided with a heating mechanism 5. The temperature detection sensor 6 is located inside the support mechanism 4. The picking and placing mechanism 2 includes a horizontal plate 21, which is fixedly installed on the upper part of the inner wall of the base 1.
[0036] A motor 22 is fixedly installed at one end of the bottom of the horizontal plate 21. The output shaft of the motor 22 is keyed to a first gear 23. A second gear 24 meshes with one side of the first gear 23. A threaded sleeve 25 is fixedly installed on the inner wall of the second gear 24. A threaded rod 26 is threadedly connected to the inner wall of the threaded sleeve 25. The threaded sleeve 25 is rotatably connected to the horizontal plate 21. A connecting plate 27 is rotatably connected to the top of the threaded rod 26. A top plate 28 is fixedly installed on both sides of the top of the connecting plate 27. A support rod 29 is fixedly installed on both sides of the bottom of the top plate 28. The bottom end of the support rod 29 slides through to the bottom of the horizontal plate 21.
[0037] The motor 22 provides power output, while the first gear 23, the second gear 24, and the threaded rod 26 provide transmission and lifting. The horizontal plate 21 and the threaded sleeve 25 provide support. The connecting plate 27 and the top plate 28 directly perform the lifting operation. The support rod 29 can limit the connecting plate 27 to assist its stable up and down movement.
[0038] Temperature sensor 6 can be used to detect the internal temperature during screening and can be used to adjust the temperature. Picking and placing mechanism 2 facilitates the picking and placing or replacing of multi-channel carriers. Support mechanism 4 can be used in conjunction with sealing mechanism 3 to improve the sealing performance after closure. Heating mechanism 5 facilitates the use of heating to perform thermal screening of catalysts.
[0039] When lifting and replacing materials:
[0040] First, the motor 22 is started, and then the motor 22 drives the first gear 23 to rotate. When the first gear 23 rotates, it drives the second gear 24 to rotate through the meshing connection. The second gear 24 drives the threaded sleeve 25 to rotate together. The threaded sleeve 25 and the horizontal plate 21 are rotated together, so the position of the horizontal plate 21 will not move upward. The threaded connection will cause the threaded rod 26 to move upward on the inner wall of the threaded sleeve 25. When the threaded rod 26 moves upward, it will lift the connecting plate 27. At this time, the connecting plate 27 drives the two sets of top plates 28 to move upward together until they contact the ceramic substrate 54, which is the carrier mentioned above. The top plates 28 can directly lift the ceramic substrate 54 upward until it is higher than or level with the connecting seat 41, so that it can be picked up or replaced.
[0041] As the top plate 28 moves upward, it will drive the two sets of support rods 29 at the bottom to move upward together. At this time, the two sets of support rods 29 will pass through the horizontal plate 21, and the top of the horizontal plate 21 is provided with a matching sliding hole, which will slide on the inner wall of the sliding hole.
[0042] After removing the screened catalyst sample, replace it with a new sample in the ceramic substrate 54 and place it in the original position. After placement, rotate the motor 22 counterclockwise and clockwise during lifting. Pull the lifting mechanism downwards again according to the threaded connection until it returns to its original position to complete the material discharge operation. This simultaneously achieves sealing and allows for hot screening.
[0043] Preferably, the sealing mechanism 3 includes a transmission component, a cover component, and a sealing component. The transmission component is located on the outside of the base 1, the cover component is located on top of the transmission component, and the sealing component is located on the bottom of the cover component. The cooperation of the transmission component, the cover component, and the sealing component enables the sealing and tightening operation after the top material is discharged.
[0044] like Figure 4 , 5 As shown in Figure 6, the transmission assembly includes a transmission plate 31, a vertical rod 32, and a sleeve plate 34. The transmission plate 31 is fixedly installed at the bottom end of the support rod 29, the vertical rod 32 is fixedly installed on the transmission plate 31, and the sleeve plate 34 is slidably sleeved on the outside of the vertical rod 32. One end of the sleeve plate 34 is fixed on the outer wall of the base 1. A limiting hole 7 is opened at the lower part of the base 1, and the transmission plate 31 passes through the limiting hole 7 to the outside of the base 1. The transmission plate 31 and the vertical rod 32 play the roles of transmission and support, while the sleeve plate 34 can assist the vertical rod 32 to move up and down stably.
[0045] like Figure 4 , 5As shown in Figure 6, the cover assembly includes a fixing plate 33, a top cover 35, and a pressure relief valve pipe 36. The fixing plate 33 is fixedly installed on the top of the vertical rod 32, and the top cover 35 is fixedly installed on the inner end of the fixing plate 33. The pressure relief valve pipe 36 passes through and connects to the top of the top cover 35. The fixing plate 33 plays a secondary transmission role, and the top cover 35 can realize the closing function. The pressure relief valve pipe 36 is composed of a pressure relief pipe and a control valve. When it is necessary to release pressure, the control valve will open to allow hot air to be discharged from the pressure relief pipe in advance. It should be noted that when the pressure relief valve pipe 36 is releasing pressure and venting air, its outlet position must be kept open and there should be no person or object above it.
[0046] like Figure 5 As shown, the sealing assembly includes a sealing seat 37 and a sealing ring 38. Both the sealing seat 37 and the sealing ring 38 are fixedly installed on the bottom of the top cover 35. The sealing seat 37 is located inside the sealing ring 38. The bottom of the pressure relief valve pipe 36 passes through the sealing seat 37. When the sealing seat 37 and the sealing ring 38 move downward, they cooperate with the ring groove 43 and the closing of the top cover 35 to improve the sealing effect.
[0047] When opened:
[0048] When the support rod 29 moves upward, it will drive the transmission plate 31 to move upward together. At this time, the transmission plate 31 drives the vertical rod 32 to move synchronously. The sleeve plate 34 has a slot that matches the vertical rod 32. Therefore, the vertical rod 32 will slide on the inner wall of the slot when it moves up and down. At the same time, the sleeve plate 34 is passed through the slot. The sleeve plate 34 is fixedly installed on the upper part of both sides of the base 1. Then the vertical rod 32 pushes the fixing plate 33. The fixing plate 33 pushes the top cover 35 and the pressure relief valve pipe 36 to move upward together. When the top cover 35 moves upward, it will drive the sealing seat 37 and the sealing ring 38 to move together.
[0049] At this time, the sealing seat 37 will detach from the inner wall of the connecting seat 41, and the sealing ring 38 will detach from the inside of the ring groove 43. Then the top of the connecting seat 41 will be in the open state, and the ceramic substrate 54 that is synchronously lifted below can be moved to the top of the connecting seat 41.
[0050] When sealing:
[0051] As described above, when the support rod 29 moves downward, it pushes the transmission plate 31. The transmission plate 31 drives the top cover 35 to move downward through the vertical rod 32 and the fixed plate 33. At this time, the top cover 35 will drive the pressure relief valve pipe 36 and the sealing seat 37 and the sealing ring 38 to move downward together until the bottom of the top cover 35 contacts the top of the connecting seat 41 and makes the two fit tightly together. At the same time, the sealing seat 37 will be inserted from top to bottom into the upper part of the inner wall of the connecting seat 41, and the sealing ring 38 will be directly inserted into the inside of the ring groove 43 to form a sealing operation.
[0052] Furthermore, the support mechanism 4 includes a connecting seat 41, which is placed on top of the base 1. A flange 44 is fixedly installed on the lower part of the outer side of the connecting seat 41 and the upper part of the outer side of the base 1. The connecting seat 41 and the base 1 are connected by the flange 44.
[0053] Both ends of the bottom of the inner cavity of the connector 41 are fixedly provided with through openings 42, and the top of the connector 41 is provided with a ring groove 43. The sealing ring 38 is located inside the ring groove 43. A temperature detection sensor 6 is fixedly installed at the bottom of the inner cavity of the connector 41, and a spring-loaded take-up device is installed on one side of the connector.
[0054] The connecting seat 41, in conjunction with the ring groove 43, enables auxiliary sealing, while the through port 42 facilitates the through extension of the top plate 28. As mentioned above, there are two sets of flanges 44, one set on the outside of the base 1 and the other set on the outside of the connecting seat 41. The flanges 44, in conjunction with bolts, facilitate a tight connection between the connecting seat 41 and the base 1, and also facilitate the installation of the connecting seat 41 on the top of the base 1. This also makes it convenient for subsequent disassembly and transportation, and also facilitates assembly.
[0055] When using:
[0056] First, the connecting seat 41 needs to be installed on the top of the base 1. Place the connecting seat 41 on the top of the base 1, and then the two sets of flanges 44 contact and fit together. At this time, ensure that the bolt holes of the two sets of flanges 44 are aligned vertically. Then, use bolts to connect the two sets of flanges 44, and then complete the fixed installation of the connecting seat 41.
[0057] During disassembly:
[0058] Simply reverse the above placement. Remove the bolts from the flange 44. Note that when installing and removing, the top cover 35 should be pushed to the top position. Finally, move the connecting seat 41 upwards, making it higher than the top plate 28. Then move the connecting seat 41 horizontally. When installing, do the opposite of the above. First, move it horizontally to the preset position, which is the top of the top plate 28, and then move it downwards.
[0059] Furthermore, the heating mechanism 5 includes a support component, a discharge component, and a heating component. The support component is located on top of the top material plate 28, the heating component is located inside the support component, and the discharge component is located on top of the support component. The support component is used to support the heating component, the heating component can realize heating control, and the discharge component can be used to place multiple groups of catalysts and realize parallel high-throughput screening of catalyst performance characterization.
[0060] like Figure 7 and 9As shown, the support assembly includes a mounting base 51 and an adapter groove 52. The support assembly is fixedly installed on the top of the top plate 28. The adapter groove 52 is opened on the top of the mounting base 51. The mounting base 51 is used to support the ceramic substrate 54, while the adapter groove 52 facilitates the insertion of the adapter block 53, thereby assisting in the formation of auxiliary limiting and support for the ceramic substrate 54.
[0061] like Figure 7 , 8 As shown in Figure 9, the feeding assembly includes an adapter block 53, a ceramic substrate 54, and a placement channel 55. The adapter block 53 is inserted into the inside of the adapter groove 52. The ceramic substrate 54 is fixedly installed on the top of the adapter block 53. The placement channel 55 is opened on the top of the ceramic substrate 54. A thermocouple 8 is installed at the bottom of the inner cavity of the placement channel 55. The arrangement of the ceramic substrate 54 and the placement channel 55 facilitates the placement of several sample crucibles with catalysts in a high-throughput and multi-channel manner, thereby enabling the screening of different catalysts or the same catalyst. Several sets of thermocouples 8 connected in series will form a thermopile and form several sets of single detection points. The detection points formed by the thermocouples 8 connected in series can be used to detect the crucibles in several sets of placement channels 55, thus forming a temperature difference sensor and outputting a heat flow signal.
[0062] The bottom of each of the other thermocouples 8 is provided with two sets of connecting wires. The end of the connecting wire away from the thermocouple 8 extends through to the outside, and the connecting wire is not fixed so that it has an extension effect when it is moved.
[0063] Among them, the spring-type take-up coil 9 is mainly used to take up and unwind the wire connected to the thermocouple 8. When needed, the wire inside the spring-type take-up coil 9 is pulled according to the upward movement of the thermocouple 8. When the thermocouple 8 descends, the released wire is taken up by the spring-type take-up coil 9 to avoid the wire from becoming tangled.
[0064] like Figure 7 and 9As shown, the heating assembly includes a mounting rod 56, a heating tube 57, a silicon controlled rectifier (SCR) temperature controller 58, and a connecting conduit 59. The mounting rod 56 is fixedly installed at the bottom of the inner cavity of the mounting base 51. The heating tube 57 is fixedly installed at the top of the mounting rod 56. The bottom end of the heating tube 57 is inserted into the connecting conduit 59. The SCR temperature controller 58 is fixedly installed on the outside of the connecting conduit 59 away from the heating tube 57. The mounting rod 56 is used to support the heating tube 57, and the heating tube 57 can be directly connected to an external circuit to achieve heating operation. The SCR temperature controller 58 is used to control the temperature of the heating tube 57 and, together with the temperature detection sensor 6, can detect the temperature of the heating environment so that operation control can be achieved through a position computer. At the same time, the SCR temperature controller 58 can be controlled to adjust the heating tube 57 up or down. The connecting conduit 59 is used to connect the heating tube 57 and the SCR temperature controller 58, and the connecting conduit 59 can also be connected to an external power supply and control equipment.
[0065] During filtering:
[0066] As described above, place the catalyst to be tested first, and place several crucibles with catalysts assembled inside the placement channel 55. Then move the ceramic substrate 54, which will move the catalyst together and move it above the connecting seat 41. Then place it in the preset position and angle. As described above, the ceramic substrate 54 will move downward. When the ceramic substrate 54 moves downward, the adapter block 53 will move downward together until the adapter block 53 is inserted into the adapter groove 52. The bottom of the ceramic substrate 54 will contact the top of the top plate 28. After it is in the preset position, the sealing operation is achieved.
[0067] During operation, the heating element 57 can be pre-activated, and the silicon controlled rectifier temperature controller 58 and the temperature sensor 6 can work simultaneously. First, the silicon controlled rectifier temperature controller 58 is used to control the heating element 57 to rise to the required temperature. Then, the internal temperature is constantly monitored by the temperature sensor 6 so that the temperature can be adjusted down by the silicon controlled rectifier temperature controller 58 when the temperature is too low or too high.
[0068] After the above steps, you can begin heating up to conduct the experiment;
[0069] The ceramic substrate 54 is a silicon nitride ceramic substrate with high thermal conductivity, high electrical insulation, high mechanical strength and low expansion. It adopts a multi-channel high-throughput method to achieve single characterization of multiple samples, which improves the catalyst screening efficiency in Fischer-Tropsch synthesis and shortens the development cycle.
[0070] The temperature control settings ensure the uniformity of sample heating within the internal temperature field.
[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
