Description

Technical Field

[0001] This utility model relates to the field of hydrogenation experimental technology, and in particular to an eight-channel continuous hydrogenation parallel screening experimental device. Background Technology

[0002] The eight-channel continuous hydrogenation parallel screening experimental device is an experimental instrument used in the field of chemical synthesis. Its core feature is that it integrates eight independent micro-reaction channels, which can simultaneously carry out eight different hydrogenation reaction experiments.

[0003] In traditional hydrogenation experimental equipment, after hydrogenation is completed, manual shaking or magnetic stirring is commonly used to mix hydrogen with reactants to initiate the reaction. However, the drawbacks of this manual mixing mode are particularly evident when applied to an eight-channel device. Because the samples in the eight channels cannot be mixed synchronously and uniformly, significant differences arise in the reaction initiation points and reaction progress of each reaction. This causes the eight experiments to lose their "parallel" comparison benchmark, compromising the fairness and accuracy of the eight-channel screening and making it impossible to achieve synchronous parallel screening.

[0004] To address this issue, an eight-channel continuous hydrogenation parallel screening experimental setup is proposed. Utility Model Content

An opening is provided on the inner wall of the slide plate. A motor is fixedly connected to the top of the test bench, and a rotating rod is fixedly connected to the output end of the motor. An eccentric wheel is fixedly connected to the outer wall of the rotating rod.

[0007] As a further description of the above technical solution: The shaking mechanism includes a drive shaft, which is rotatably connected to the inner wall of the test bench. The inner wall of the test bench is rotatably connected to a driven shaft, and both the driven shaft and the drive shaft are fixedly connected to a rotating shaft at their top ends.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 3 The present invention provides an embodiment of an eight-channel continuous hydrogenation parallel screening experimental device, comprising a test bench 1, a mounting frame 2, and a flow equalization mechanism 3; A Y-shaped tube 4 is fixedly connected through and fixed to the top of the test bench 1. A threaded joint 5 is fixedly connected to the top of the Y-shaped tube 4. The two threaded joints 5 at the top of the Y-shaped tube 4 are connected to the reactant delivery pipe and the hydrogen delivery pipe respectively. The reactant and hydrogen can be delivered to the inner wall of the sleeve 31 through the Y-shaped tube 4. The inner wall of the mounting frame 2 is provided with a slot 6, and a test cup 7 is placed inside the slot 6. The inner wall of the test bench 1 is provided with a shaking mechanism 8. The mounting frame 2 is driven to shake back and forth by the shaking mechanism 8, which can make the test cup 7 placed inside the slot 6 shake synchronously, so that the reactants inside the test cup 7 are evenly mixed and the reaction speed is improved. Reference Figure 2 , Figure 5 and Figure 6The flow equalization mechanism 3 includes a sleeve 31, which is rotatably connected to the outer wall of the Y-shaped tube 4. A guide plate 32 is fixedly connected to the inner wall of the sleeve 31, and a driven gear 33 is fixedly connected to the outer wall of the sleeve 31. When the driven gear 33 reciprocates, it drives the sleeve 31 to reciprocate synchronously on the outer wall of the Y-shaped tube 4. A slide plate 34 is slidably connected to the inner wall of the test bench 1. A rack 35 that meshes with the driven gear 33 is fixedly connected to the side wall of the slide plate 34. When the slide plate 34 reciprocates, it drives the rack 35 to reciprocate synchronously. At this time, the rack 35 drives the driven gear 33 that meshes with it to reciprocate. An opening 36 is opened on the inner wall of the slide plate 34. Under the radial restriction of the opening 36, the eccentric wheel 39 can push and pull the slide plate 34 back and forth while rotating, so that the slide plate 34 reciprocates on the inner wall of the test bench 1.

[0020] Reference Figure 2 and Figure 4 A motor 37 is fixedly connected to the top of the test bench 1. A rotating rod 38 is fixedly connected to the output end of the motor 37. An eccentric wheel 39 is fixedly connected to the outer wall of the rotating rod 38. When the motor 37 is started, it drives the rotating rod 38 to rotate. When the rotating rod 38 rotates, it will drive the eccentric wheel 39 to move back and forth against the inner wall of the opening 36.

[0021] Reference Figure 5 At least three sets of guide plates 32 are equidistantly arranged along the axial direction of the sleeve 31, and adjacent sets of guide plates 32 are staggered. Through multiple staggered and equidistant guide plates 32, the gas and liquid can flow in a zigzag pattern inside the sleeve 31, which is beneficial to enhance the turbulence effect of gas and liquid and thus improve the gas-liquid mixing efficiency.

[0022] Reference Figure 6 The axis of the eccentric wheel 39 is offset from the axis of the rotating rod 38. The outer wall of the eccentric wheel 39 is attached to the inner wall of the opening 36. When the rotating rod 38 rotates, it will drive the eccentric wheel 39 to move back and forth against the inner wall of the opening 36. At this time, under the restriction of the opening 36, the eccentric wheel 39 will push and pull the slide plate 34 back and forth while rotating, so that the slide plate 34 slides back and forth on the inner wall of the test bench 1.

[0023] Reference Figure 2 - Figure 4The shaking mechanism 8 includes a drive shaft 81, which is rotatably connected to the inner wall of the test bench 1. A driven shaft 84 is rotatably connected to the inner wall of the test bench 1. The drive shaft 81 and the driven shaft 84 are connected by a transmission belt 85. When the drive shaft 81 rotates, it can drive the driven shaft 84 to rotate synchronously on the inner wall of the test bench 1 in conjunction with the transmission belt 85. A rotating shaft 86 is fixedly connected to the top of both the driven shaft 84 and the drive shaft 81. A rotating rod 38 passes through and is rotatably connected to the inner wall of the test bench 1. A drive gear 83 is fixedly connected to the bottom of the rotating rod 38. When the rotating rod 38 rotates, it will drive the drive gear 83 to rotate synchronously. A gear disk 82 is fixedly connected to the outer wall of the drive shaft 81. The gear disk 82 meshes with the drive gear 83. When the drive gear 83 rotates, it will drive the gear disk 82 to rotate. When the gear disk 82 rotates, it will drive the drive shaft 81 to rotate on the inner wall of the test bench 1.

[0024] Reference Figure 3 The drive shaft 81 and its top rotating shaft 86 are eccentric. When the drive shaft 81 rotates, it drives the top rotating shaft 86 to make a circular motion around the axis of the drive shaft 81. The driven shaft 84 and its top rotating shaft 86 are eccentric. When the driven shaft 84 rotates, it drives the top rotating shaft 86 to make a circular motion around the driven shaft 84. The rotating shaft 86 is rotatably connected to the inner wall of the mounting frame 2. The two sets of rotating shafts 86 making circular motion can drive the mounting frame 2 to shake back and forth inside the test bench 1, so that the reactants inside the test cup 7 are evenly mixed and the reaction speed is improved.

[0025] Working principle: The two threaded connectors 5 at the top of the Y-shaped tube 4 are connected to the reactant delivery tube and the hydrogen delivery tube, respectively. The reactant and hydrogen can be delivered to the inner wall of the sleeve 31 through the Y-shaped tube 4. At this time, the reactant and hydrogen flowing downward inside the sleeve 31 will form a zigzag flow path under the action of multiple sets of staggered guide plates 32. The multiple sets of staggered guide plates 32 can increase the turbulence effect inside the sleeve 31. By increasing the turbulence effect, the gas-liquid boundary layer can be destroyed, thereby improving the gas-liquid mixing efficiency. After mixing, the reactant and hydrogen will finally enter the interior of the test cup 7.

[0026] While the Y-tube 4 is conveying reactants and hydrogen, the motor 37 is activated, driving the rotating rod 38 to rotate. As the rotating rod 38 rotates, it causes the eccentric wheel 39 to reciprocate against the inner wall of the opening 36. Under the constraint of the opening 36, the eccentric wheel 39, while rotating, reciprocates by pushing and pulling the slide plate 34, causing the slide plate 34 to slide back and forth against the inner wall of the test bench 1. Simultaneously, the slide plate 34 drives the rack 35 to reciprocate. The rack 35 then drives the driven gear 33, which meshes with it, to rotate reciprocally. The driven gear 33 then drives the sleeve... The tube 31 reciprocates on the outer wall of the Y-shaped tube 4. When the gas and liquid flow along the axial direction of the sleeve 31, the multiple sets of baffles arranged in a staggered manner on the inner wall of the sleeve 31 will continuously change the direction of gas and liquid flow during the reciprocating rotation of the sleeve 31, causing the gas and liquid to collide with each other, thereby further improving the gas-liquid mixing efficiency. This ensures that the reactants and hydrogen are fully mixed together before entering the test cup 7, eliminating the need to manually stir the reactants on the hydrogenation shaft. This ensures that the test samples inside the eight test cups 7 react synchronously, allowing staff to observe the eight test cups 7 and perform parallel screening.

[0027] While rotating, the rotating rod 38 drives the drive gear 83 to rotate synchronously. At this time, the drive gear 83 drives the meshing gear disk 82 to rotate. While rotating, the gear disk 82 drives the drive shaft 81 to rotate on the inner wall of the test bench 1. While rotating, the drive shaft 81, in conjunction with the transmission belt 85, drives the driven shaft 84 to rotate synchronously on the inner wall of the test bench 1. While rotating, the drive shaft 81 drives the rotating shaft 86 at its top to rotate around the axis of the drive shaft 81. At the same time, while rotating, the driven shaft 84 drives the rotating shaft 86 at its top to rotate around the driven shaft 84. At this time, the two sets of rotating shafts 86 can reciprocate to push the mounting frame 2, causing the mounting frame 2 to swing back and forth horizontally inside the test bench 1. The reciprocating swing of the mounting frame 2 can drive the test cup 7 placed inside the slot 6 to swing synchronously, so that the reactants inside the test cup 7 are evenly mixed, improving the reaction speed and thus improving the experimental efficiency.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
