Description

Technical Field

[0001] This invention relates to the field of catalytic equipment technology, and more specifically, to a device for research on photocatalytic and enzyme-catalyzed combined reactions. Background Technology

[0002] Photocatalysis and enzyme catalysis, as cutting-edge catalytic technologies, have each shone brightly in numerous fields. Photocatalysis, by exciting catalysts with light energy, has shown great potential in wastewater treatment, solar hydrogen production, and other fields. Enzyme catalysis, with its extremely high catalytic efficiency and specificity, plays a crucial role in chemical reactions in organisms and in industries such as biopharmaceuticals and food processing. Theoretically, combining photocatalysis and enzyme catalysis to form a composite reaction system can leverage the advantages of both, opening up new pathways for more efficient and selective catalytic reactions. However, existing photocatalytic-enzyme composite catalytic reaction devices struggle to achieve uniform catalysis of materials. In photocatalysis, the light distribution cannot uniformly cover the reactants, resulting in inconsistent light energy received by different parts of the material. For example, in common photocatalytic reactors, the light source is often unilateral or at a limited angle, creating blind spots within the material, causing only some materials to fully participate in the photocatalytic reaction, reducing overall reaction efficiency and material utilization. For enzyme catalysis, the uniformity of mixing in the reaction system directly affects the contact probability between the enzyme and the substrate. To ensure timely binding of the substrate to the enzyme, existing catalytic equipment often relies on manual stirring of the materials to achieve a mixing effect. However, this method is labor-intensive, inefficient, and produces poor mixing results, thus requiring improvement. Utility Model Content

Detailed Implementation

[0032] 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.

[0033] like Figures 1 to 8 As shown, this utility model provides an apparatus for studying photocatalytic and enzyme-catalyzed combined reactions, comprising:

[0034] The casing 1 has a catalyst chamber 2 fixedly installed inside the casing 1. The catalyst chamber 2 is made of transparent material. The feed pipe 3 is fixedly connected to the top of the casing 1 and the catalyst chamber 2.

[0035] A stirring mechanism is located at the top of the casing 1;

[0036] A rotating mechanism is located at the top inside the housing 1;

[0037] The rotating mechanism includes a ring 4, the top of which is fixedly connected to the top of the inside of the housing 1. A rotating block 5 is movably connected to the bottom of the ring 4. A gear ring 6 is fixedly sleeved on the outer surface of the rotating block 5. A gear 7 is meshed with the outer surface of the gear ring 6. A rotating shaft 8 is fixedly sleeved inside the gear 7. A driven wheel 9 is fixedly sleeved at the top of the outer surface of the rotating shaft 8. A catalytic lamp tube 10 is fixedly sleeved inside the rotating block 5. A rotating ring 11 is fixedly sleeved at the bottom of the outer surface of the catalytic lamp tube 10. A support ring 12 is movably sleeved on the outer surface of the rotating ring 11. The outer surface of the support ring 12 is fixedly sleeved inside the housing 1.

[0038] Due to the design of the feed pipe 3, the material can enter the interior of the catalytic chamber 2 through the feed pipe 3. Since the catalytic chamber 2 is made of transparent material, the light generated by the catalytic lamp tube 10 can catalyze the material. When the driven wheel 9 rotates, it will drive the gear 7 to rotate through the rotating shaft 8. Since the gear 7 meshes with the gear ring 6, the gear 7 will drive the rotating block 5 to rotate along the inside of the ring 4 through the gear ring 6. At this time, the rotating block 5 will drive the catalytic lamp tube 10 to rotate along the inside of the housing 1. During this process, the catalytic lamp tube 10 will irradiate the material inside the catalytic chamber 2 evenly, so that the material can undergo uniform photocatalytic treatment. At the same time, the catalytic lamp tube 10 will drive the rotating ring 11 to rotate along the inside of the support ring 12. Due to the design of the rotating ring 11 and the support ring 12, the catalytic lamp tube 10 will play a good supporting role, making the catalytic lamp tube 10 more stable when rotating.

[0039] The stirring mechanism includes:

[0040] The bottom end of the fixed frame 13 is fixedly connected to the top end of the housing 1, and the interior of the left end of the fixed frame 13 is movably sleeved with the outer surface of the rotating shaft 8.

[0041] The bottom end of the motor 14 is fixedly connected to the top end of the fixed frame 13. The other end of the output shaft of the motor 14 is fixedly sleeved with a long shaft 15. The outer surface of the long shaft 15 is respectively movably sleeved with the inner top of the housing 1 and the catalyst chamber 2. The outer surface of the long shaft 15 is fixedly sleeved with a stirring blade 16.

[0042] When the motor 14 is running, the long shaft 15 will drive the stirring blade 16 to rotate. At this time, the stirring blade 16 will stir and mix the material inside the catalytic chamber 2, so that the enzyme can be organically combined with the material in an efficient and uniform manner.

[0043] Among them, a drive wheel 17 is fixedly sleeved on the outer surface of the long shaft 15, and the drive wheel 17 is connected to the driven wheel 9 through a transmission belt 18.

[0044] When the long shaft 15 rotates, it will drive the drive wheel 17 to rotate. At this time, the drive wheel 17 will drive the driven wheel 9 to rotate through the transmission belt 18.

[0045] Among them, a fixing ring 19 is fixedly sleeved on the outer surface of the housing 1, and a bracket 20 is fixedly installed at the bottom end of the fixing ring 19.

[0046] Due to the design of the fixing ring 19 and the bracket 20, the overall housing 1 will be well supported, and the entire Shudie housing 1 can be placed stably on the ground.

[0047] The casing 1 and the bottom of the catalyst chamber 2 are internally fixedly connected to a discharge pipe 21, and a valve 22 is installed on the discharge pipe 21.

[0048] Due to the design of the discharge pipe 21, the material that has completed catalysis inside the catalytic chamber 2 can move out of the catalytic chamber 2 through the discharge pipe 21. Due to the design of the valve 22, the operator can control the opening and closing of the discharge pipe 21.

[0049] The bottom of the housing 1 is fixedly installed with a fixing rod 23, the outer surface of the fixing rod 23 is fixedly sleeved with a resistance wire 24, the top of the outer surface of the fixing rod 23 is fixedly installed with a power transmission rod 25, the top of the power transmission rod 25 is fixedly installed with a power transmission ring 26, and the power transmission ring 26 is fixedly connected to the inside of the bottom of the housing 1.

[0050] When power is delivered to the inside of the resistance wire 24, the resistance wire 24 will then deliver power to the inside of the transmission pole 25, and the transmission pole 25 will then deliver power to the inside of the transmission ring 26.

[0051] The top of the power transmission ring 26 is internally slidably connected to a power transmission block 27, and the top of the power transmission block 27 is fixedly connected to the bottom of the catalytic lamp tube 10.

[0052] When power enters the power transmission block 27, the power transmission block 27 will supply power to the catalytic lamp tube 10, at which point the catalytic lamp tube 10 will be lit.

[0053] Among them, a threaded rod 28 is fixedly installed on the left side of the bottom end of the housing 1, and a moving block 29 is threadedly sleeved on the outer surface of the threaded rod 28.

[0054] Since the moving block 29 is threadedly connected to the outer surface of the threaded rod 28, it will move upwards simultaneously when it rotates along the outer surface of the threaded rod 28.

[0055] Among them, a motion ring 30 is fixedly installed at the bottom end of the motion block 29, and a conductive rod 31 is movably sleeved at the bottom end of the outer surface of the motion ring 30.

[0056] When the moving block 29 rotates and moves upward, the moving ring 30 will rotate and move upward under the drive of the moving block 29. At this time, the moving ring 30 will pull the conductive rod 31, causing the conductive rod 31 to move upward.

[0057] Among them, a movable block 32 is fixedly installed on the right end of the conductive rod 31. The interior of the movable block 32 is movably connected to the outer surface of the resistance wire 24. A vertical rod 33 is movably sleeved inside the outer surface of the movable block 32. The top and bottom ends of the vertical rod 33 are fixedly connected to the outer surface of the fixed rod 23.

[0058] When the wire on the conductive rod 31 is connected to the power source, it will supply power to the movable block 32. At this time, the movable block 32 will supply power to the resistance wire 24. When the conductive rod 31 drives the movable block 32 to move upward along the outer surface of the vertical rod 33, the resistance in the power transmission system will decrease, thereby increasing the brightness of the catalytic lamp tube 10, so as to achieve the effect of controlling the brightness of the catalytic lamp tube 10. Due to the design of the vertical rod 33, the movable block 32 will be more stable when moving up and down.

[0059] Working principle and usage process of this utility model:

[0060] First, the operator feeds the material into the catalytic chamber 2 through the feed pipe 3. Then, the operator connects the wire on the conductive rod 31 to the power supply. The conductive rod 31 then supplies power to the movable block 32, which in turn supplies power to the transmission rod 25 through the resistance wire 24. The transmission rod 25 then supplies power to the transmission block 27 through the transmission ring 26. The transmission block 27 then supplies power to the catalytic lamp 10, causing it to light up. Since the catalytic chamber 2 is made of transparent material, the catalytic lamp 10 will then perform a photocatalytic reaction on the material inside the catalytic chamber 2. Next, the operator starts the motor 14. The long shaft 15 will simultaneously drive the stirring blade 16 and the drive wheel 17 to rotate. Due to the design of the stirring blade 16, its rotation will stir and mix the material inside the catalytic chamber 2. This allows the enzyme to combine with the material efficiently and uniformly. At the same time, the drive wheel 17 drives the driven wheel 9 to rotate via the transmission belt 18. The driven wheel 9 then drives the gear 7 to rotate via the rotating shaft 8. Since the outer surface of the gear 7 meshes with the outer surface of the gear ring 6, the rotation of the gear 7 will drive the gear ring 6 to rotate. The gear ring 6 will then drive the rotating block 5 to rotate along the inside of the ring 4. The rotating block 5 will then drive the catalytic lamp tube 10 to rotate along the inside of the housing 1. Since the material inside the catalytic chamber 2 is constantly moving under the stirring of the stirring blade 16, the catalytic lamp tube 10 will uniformly irradiate the material inside the catalytic chamber 2 during rotation. This allows the catalytic lamp tube 10 to perform uniform photocatalytic treatment on the material inside the catalytic chamber 2, thereby achieving the function of uniform catalysis of the material.

[0061] When the operator needs to adjust the brightness of the catalytic lamp 10 to study the catalytic effect of materials under different light intensities, the operator rotates the moving block 29. Since the inside of the moving block 29 is threadedly connected to the outer surface of the threaded rod 28, the moving block 29 will rotate upwards along the outer surface of the threaded rod 28. At this time, the moving ring 30 will rotate and move upwards under the influence of the moving block 29. The moving ring 30 will then pull the conductive rod 31, causing it to move upwards. Because the outer surface of the moving ring 30 is threadedly connected to the outer surface of the threaded rod 28, the moving ring 29 will rotate upwards along the outer surface of the threaded rod 28. The internal movable sleeve of 1 ensures that the conductive rod 31 will not be affected by the rotation of the moving ring 30. At the same time, the conductive rod 31 will drive the movable block 32 to move upward along the outer surface of the vertical rod 33. Due to the design of the vertical rod 33, the movable block 32 will be more stable when moving up and down. Due to the design of the movable block 32 and the resistance wire 24, when the movable block 32 moves upward, the resistance in the power transmission line will be reduced, thereby increasing the brightness of the catalytic lamp tube 10. This realizes the function of conveniently adjusting the brightness of the catalytic lamp tube 10 according to experimental needs.
