The push block 35 is arranged inside the injection groove 34. The reset assembly is arranged on the injection groove 34. When the follower rod 28 rotates, the push block 35 will move repeatedly inside the injection groove 34 through the reset assembly. When the push block 35 moves, it can press the liquid entering the injection groove 34, so that the liquid is injected and mixed to one side, thereby improving the mixing efficiency.

[0043] As Figure 6 and Figure 7 shown, the reset assembly includes a connecting shaft 36 and a reset spring 37. One end of the connecting shaft 36 is fixedly connected with the central position of the push block 35, and one end of the connecting shaft 36 penetrates through the injection groove 34.

The movement of the connecting shaft 36 will drive the push block 35 to move. The reset of the reset spring 37 will drive the connecting shaft 36 to move, and the movement of the connecting shaft 36 will drive the push block 35 to reset, thereby repeatedly driving the push block 35 to move and repeatedly ejecting and mixing the liquid entering the injection groove 34 outward.

[0044] As Figure 7 and Figure 8 shown, a convex block 38 is fixedly installed on the follower rod 28, and the convex block 38 is located on one side of the connecting shaft 36. When the follower rod 28 rotates, it will drive the convex block 38 to move. When the convex block 38 moves, it can drive the connecting shaft 36 to move.

[0045] As Figure 8 、 Figure 9 and Figure 10As shown in the figure, diversion grooves 39 are symmetrically arranged on the driving rod 8. Spray holes 40 are arranged in an array on the diversion grooves 39, and the spray holes 40 are designed to prevent backflow. An air box 41 is fixedly installed on the inner wall of the reaction tank 1. A filter plate 42 is arranged on the top of the air box 41. A blower 43 is fixedly installed inside the air box 41. A shaft body 44 is fixedly connected to the center position of the impeller inside the blower 43, and the shaft body 44 is in transmission connection with the driving wheel 10 through a belt. A stopper 45 is fixedly installed inside the movable groove 22. A groove body 46 is arranged inside the driven rod 28. Driven shafts 47 are arranged in an array inside the groove body 46.

A limiting block 50 is fixedly installed inside the groove body 46, and the limiting block 50 is located on one side of the collision plate 48. The rotation of the driving rod 8 drives the blower 43 to move through the driving wheel 10 and the shaft body 44, and then wind flow will be generated. A rotary joint is connected to the bottom end of the driving rod 8. The output end of the blower 43 is connected to the rotary joint, and the rotary joint is communicated with the diversion groove 39. Thus, the wind can flow into the mixed liquid for catalytic reaction. If an oxidation reaction or a reaction that requires the participation of oxygen is needed, the above structure can be driven to add air to improve the reaction effect. If air intervention in the reaction is not required, the belt between the shaft body 44 and the driving wheel 10 can be removed. Thus, when the driving rod 8 rotates, the shaft body 44 will not rotate, that is, air will not flow into the diversion groove 39 to participate in the reaction. The rotation of the driven rod 28 drives the circumferential rotation of the driven shafts 47. One end of the driven shaft 47 is arc-shaped. When the driven shaft 47 moves and contacts the stopper 45, the driven shaft 47 will slide into the groove body 46. When the driven shaft 47 is no longer in contact with the stopper 45, the driving spring 49 will reset and push the collision plate 48 to reset. When the collision plate 48 resets and contacts the limiting block 50, the movable groove 22 will be slightly vibrated through the driven rod 28. When the movable groove 22 vibrates, the cleaning ring 16 will be slightly vibrated. When the cleaning ring 16 vibrates, the impurities adsorbed on the cleaning ring 16 can be removed. Thus, the cleanliness of the cleaning ring 16 can be improved, and it can be avoided that the adsorbed substances are adsorbed on the cleaning ring 16 and are not easy to be removed later. Moreover, the slight vibration of the cleaning ring 16 can improve the mixing efficiency of the mixed liquid.

[0046] A method for using an L-tartaric acid catalytic reaction device, comprising: (1) Synthesis reaction Maleic anhydride is added to water and stirred until dissolved, then calcium carbonate and hydrogen peroxide are added, and calcium epoxy succinate is synthesized under the catalysis of tungstic acid. (2) Biocatalysis The above reaction solution is adjusted to pH 7.5 - 8.0 with disodium epoxy succinate, and a Nocardia biocatalyst is added for biotransformation reaction to generate calcium L-tartrate and sodium tartrate. After filtration, calcium L-tartrate crystals are obtained. (4) Acidolysis reaction Calcium L-tartrate is stirred with water, concentrated sulfuric acid is added to generate L-tartaric acid and calcium sulfate, and L-tartaric acid is obtained by filtration and decolorized with activated carbon; (5) Product refinement The decolorized L-tartaric acid contains certain anionic and cationic impurity ions. The impurity ions are exchanged through anion and cation columns, and the exchanged mixed solution is vacuum concentrated to precipitate solid L-tartaric acid.

[0047] Working principle: When using the L-tartaric acid catalytic reaction device, after adding the raw materials (calcium epoxy succinate reaction solution, disodium epoxy succinate, Nocardia biocatalyst) into the interior of the reaction tank 1 through the feeding pipe 5, control the driving motor 7 to work to drive the driving rod 8 to rotate. When the driving rod 8 rotates, it drives the stirring blade 9 to rotate, and then the raw materials will be stirred and mixed. When the driving rod 8 rotates, it drives the driving wheel 10 to rotate. The rotation of the driving wheel 10 drives the reciprocating screw rod 13 to rotate through the cooperation of the belt and the driven wheel 15. When the reciprocating screw rod 13 rotates, the threaded ring 19 moves, and then drives the cleaning ring 16 to move through the connecting block 18. At the same time, it drives the guiding block 20 to slide on the guide rod 14, so that the cleaning ring 16 can move smoothly. When the cleaning ring 16 moves, it can scrape and mix the materials adsorbed on the inner wall of the reaction tank 1, improving the mixing efficiency and the cleanliness of the inner wall of the reaction tank 1, and preventing the mixed raw materials from adsorbing on the inner wall of the reaction tank 1 and affecting the mixing reaction efficiency. The rack 21 is fixedly installed inside the reaction tank 1. When the cleaning ring 16 moves, it drives the transmission gear 23 to move through the movable groove 22, causing the transmission gear 23 to rotate. When the transmission gear 23 rotates, it drives the driving shaft 25 to rotate inside the support ring 24. Then, through the driving shaft 25, the first belt pulley 26 is driven to rotate. Through the cooperation of the driving belt 27 and the second belt pulley 29, the driven rod 28 is driven to rotate. The rotation of the driven rod 28 drives the driving gear 30 to rotate. Through the cooperation of the driven gear 32, the rotating shaft 31 is driven to rotate. When the rotating shaft 31 rotates, it drives the spoiler blade 33 to rotate. When the spoiler blade 33 rotates, the liquid in contact with the spoiler blade 33 flows longitudinally, thereby improving the mixing efficiency of the liquid. When the driven rod 28 rotates, it drives the convex block 38 to move. One side of the convex block 38 contacts the connecting shaft 36, pushing the connecting shaft 36 to move. The movement of the connecting shaft 36 drives the push block 35 to move. The reset spring 37 resets to drive the connecting shaft 36 to move, and the movement of the connecting shaft 36 drives the push block 35 to reset, thereby repeatedly driving the push block 35 to move and repeatedly ejecting the liquid entering the injection groove 34 outward for mixing, further improving the mixing efficiency of the mixed liquid. When the driving rod 8 rotates, it drives the blower 43 to move through the driving wheel 10 and the shaft body 44, generating wind flow. A rotary joint is connected to the bottom end of the driving rod 8. The output end of the blower 43 is connected to the rotary joint, and the rotary joint is connected to the diversion groove 39. Then, the wind can flow into the mixed liquid for catalytic reaction. If an oxidation reaction or a reaction that requires oxygen participation is needed, the above structure can be driven to move to introduce air to improve the reaction effect. If air intervention in the reaction is not required, the belt between the shaft body 44 and the driving wheel 10 can be removed. Then, when the driving rod 8 rotates, the shaft body 44 will not rotate, that is, air will not flow into the diversion groove 39 to participate in the reaction. The rotation of the driven rod 28 drives the driven shaft 47 to rotate circumferentially. One end of the driven shaft 47 is arc-shaped. When the driven shaft 47 moves, it contacts the stop block 45, causing the driven shaft 47 to slide into the groove body 46. When the driven shaft 47 no longer contacts the stop block 45,When the driving spring 49 resets, it will push the collision plate 48 to reset. When the collision plate 48 resets and contacts the limit block 50, the movable groove 22 will vibrate slightly through the driven rod 28. When the movable groove 22 vibrates, the cleaning ring 16 will vibrate slightly. When the cleaning ring 16 vibrates, the impurities adsorbed on the cleaning ring 16 can be removed, thereby improving the cleanliness of the cleaning ring 16, avoiding the adsorption of adsorbates on the cleaning ring 16, which is not easy to remove later, and the slight vibration of the cleaning ring 16 can improve the mixing efficiency of the mixed liquid.
