DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1 to 5As shown, a toluene production stirring device described in an embodiment of the utility model comprises a stirring barrel 1; a lifting assembly 12 is installed near the outside of the stirring barrel 1; a hollow shaft 13 is rotatably connected to the middle of the lifting assembly 12; a motor 14 is fixedly connected to the bottom of the lifting assembly 12; a first gear 15 is fixedly connected to the middle of the output end of the motor 14; a second gear 16 is fixedly connected to the middle of the hollow shaft 13; the first gear 15 and the second gear 16 are meshingly arranged; a feeding hopper 17 is fixedly connected to the top of the hollow shaft 13; the feeding hopper 17 is connected to the hollow shaft 13; the bottom end of the hollow shaft 13 is connected to a hollow rod 18; when working, the motor 14 is started to drive the hollow shaft 13 to rotate, and then the hollow rod 18 is driven to rotate, so that the hollow rod 18 stirs the reaction material inside the stirring barrel 1, and when it is needed to add When a new solvent is added, the solvent is added to the inside of the hopper 17, and then the solvent will enter the inside of the hollow rod 18 along the hollow shaft 13, and then flow out from both ends of the hollow rod 18 to mix with the reaction material being stirred. At the same time, as the hollow rod 18 rotates, the solvent will be thrown into the reaction material inside the stirring barrel 1 more evenly. At the same time, as the solvent inside the hollow rod 18 is thrown out, a negative pressure will be formed inside the hollow rod 18, thereby quickly sucking the solvent inside the hopper 17 into the inside of the hollow shaft 13, so that the solvent inside the hopper 17 can be quickly drawn into the inside of the stirring barrel 1, thereby increasing the feeding speed of the solvent. Through the above structure, when the reaction material is stirred, the new reaction solvent can be injected into the bottom of the reaction material through the hollow rod 18, thereby reducing the occurrence of solution splashing, and further reducing the pollution to the environment around the device.

[0026] like Figures 1 to 4 As shown, the side wall of the hollow shaft 13 is fixedly connected with a plurality of pairs of fixing rods 2; the middle part of the fixing rod 2 is slidably connected with a slide cylinder 21; the inner side wall of the fixing rod 2 is fixedly connected with a spring 22; the other end of the spring 22 is fixedly connected to the inner side wall of the slide cylinder 21; each pair of the side walls of the slide cylinder 21 is fixedly connected with a fixing plate 23; the fixing plate 23 is fixedly connected with a plurality of bristles 24 on the side away from the hollow shaft 13; the plurality of bristles 24 are densely distributed on the side wall of the fixing plate 23; during operation, after the reaction materials inside the mixing barrel 1 complete the reaction, the output is taken out, and then the inside of the mixing barrel 1 needs to be cleaned. During cleaning, the motor 14 is started to drive the hollow shaft 13 to rotate. At this time, the slide 21 will slide toward the side wall of the mixing barrel 1 in the middle of the fixed rod 2 due to the centrifugal force, so that the bristles 24 are in contact with the inner wall of the mixing barrel 1. As the bristles 24 rotate, the inner wall of the mixing barrel 1 can be scrubbed to remove the residual solution on the inner wall of the mixing barrel 1. Through the above structure, after the device is used, the residual solution on the inner wall of the mixing barrel 1 can be reduced, thereby reducing the impact of the residual solution on the next reaction.

[0027] like Figures 1 to 5 As shown, both ends of the hollow rod 18 are hinged with a cover 3; a fixing block 31 is fixedly connected to the middle of the inner side of the hollow rod 18 near the end; an elastic rope 32 is fixedly connected to the middle of the fixing block 31; the other end of the elastic rope 32 is fixedly connected to the side wall of the cover 3; when working, when the solvent is added to the inside of the mixing barrel 1 through the feeding hopper 17, the solvent will fall into the inside of the hollow rod 18, and as the hollow rod 18 rotates, the solvent inside the hollow rod 18 will squeeze the cover 3 under the action of centrifugal force, so that the cover 3 is separated from the end of the hollow rod 18, so that the solvent can leave The interior of the hollow rod 18 is opened. After the new solvent is added, the solution in the hollow rod 18 is completely thrown out. At this time, the cover 3 is no longer impacted by the water flow from the inside of the hollow rod 18, so that the cover 3 will seal the end of the hollow rod 18 under the tension of the elastic rope 32, making it difficult for the stirred reaction material in the mixing barrel 1 to flow into the interior of the hollow rod 18, and after the device stops stirring, there will be almost no solution residue in the hollow rod 18. Through the above structure, after stirring is completed, the solution residue in the hollow rod 18 can be reduced, thereby reducing the impact on the next use.

[0028] like Figures 1 to 3 As shown, a connecting rod 4 is fixedly connected to the middle part of each pair of fixed rods 2; a plurality of spoilers 41 are rotatably connected to the side walls of the connecting rods 4; during operation, as the hollow shaft 13 rotates, the plurality of spoilers 41 will rotate synchronously, thereby stirring the reactants inside the mixing barrel 1, and at the same time, the spoilers 41 will rotate due to the impact of the water flow, disrupting the passing water flow, so that the reactants inside the mixing barrel 1 can be fully mixed, thereby increasing the reaction speed.

[0029] like Figures 1 to 3 As shown, a bearing 5 is fixedly connected to the middle of the hollow shaft 13; a dust cover 51 is fixedly connected to the outer ring of the bearing 5; during operation, when the lower end of the hollow shaft 13 is extended into the interior of the mixing barrel 1 through the operation of the lifting component 12, the dust cover 51 will enter the interior of the mixing barrel 1, thereby sealing the top of the mixing barrel 1, making it difficult for external impurities to enter the interior of the mixing barrel 1 and cause pollution to the reaction materials.

[0030] like Figures 1 to 3 As shown, a fixing ring 6 is fixedly connected to the middle part of the inner side of the mixing barrel 1; a capsule 61 is fixedly connected to the bottom of the dust cover 51; during operation, as the dust cover 51 descends, the bottom of the capsule 61 will fit tightly with the top of the fixing ring 6, further preventing external impurities from entering the interior of the mixing barrel 1 and contaminating the reaction materials. At the same time, the setting of the capsule 61 can slightly reduce the diameter of the dust cover 51, thereby reducing the occurrence of collision between the dust cover 51 and the top of the mixing barrel 1.

[0031] like Figure 1 to Figure 2As shown, the top of the feeding hopper 17 is rotatably connected to a cover plate 7; magnets 71 are fixedly connected to the middle of the cover plate 7 and the feeding hopper 17; a pair of magnets 71 are arranged to attract each other; when working, after the solution is filled through the feeding hopper 17, the cover plate 7 is rotated to close the top of the feeding hopper 17, and at the same time, the pair of magnets 71 will attract each other, making it difficult for the cover plate 7 to be deflected due to the vibration of the equipment. Through the above structure, the occurrence of external impurities entering the interior of the mixing barrel 1 through the feeding hopper 17 and causing contamination to the reaction materials can be reduced.

[0032] like Figure 4 As shown, a through groove 8 is provided in the middle of the spring 22 and the slide cylinder 21; the through groove 8 is set to penetrate the spring 22 and the slide cylinder 21; during operation, when the slide cylinder 21 slides along the middle of the fixed rod 2, the existence of the through groove 8 can enable the solution or air inside the stirring barrel 1 to easily enter the interior of the fixed rod 2, thereby reducing the difficulty in sliding the slide cylinder 21 due to the pressure inside the fixed rod 2.

[0033] During operation, the start motor 14 drives the hollow shaft 13 to rotate, and then drives the hollow rod 18 to rotate, so that the hollow rod 18 stirs the reaction material inside the mixing barrel 1. When new solvent needs to be added, the solvent is added to the inside of the hopper 17, and then these solvents will enter the inside of the hollow rod 18 along the hollow shaft 13, and then flow out from both ends of the hollow rod 18 to mix with the reaction material being stirred. At the same time, as the hollow rod 18 rotates, the solvent will be thrown into the reaction material inside the mixing barrel 1 more evenly. At the same time, as the solvent inside the hollow rod 18 is thrown out, a negative pressure will be formed inside the hollow rod 18, so that the solvent inside the hopper 17 is quickly sucked into the hollow shaft 13, so that the solvent inside the hopper 17 can be quickly drawn out. The mixing barrel 1 is filled with solvent and the feeding speed of the solvent is increased. After the reaction materials in the mixing barrel 1 complete the reaction, the output is taken out, and then the inside of the mixing barrel 1 needs to be cleaned to reduce the influence of the residual output on the next reaction. When cleaning, the motor 14 is started to drive the hollow shaft 13 to rotate. At this time, the slide cylinder 21 will slide toward the side wall of the mixing barrel 1 in the middle of the fixed rod 2 due to the centrifugal force, so that the bristles 24 contact the inner wall of the mixing barrel 1. As the bristles 24 rotate, the inner wall of the mixing barrel 1 can be brushed to brush off the residual solution on the inner wall of the mixing barrel 1. When the solvent is added to the inside of the mixing barrel 1 through the feeding hopper 17, the solvent will fall into the inside of the hollow rod 18. As the hollow rod 18 rotates, the solvent will fall into the inside of the hollow rod 18. , the solvent in the hollow rod 18 will squeeze the cover 3 under the action of centrifugal force, so that the cover 3 is separated from the end of the hollow rod 18, so that the solvent can leave the hollow rod 18. After the new solvent is added, the solution in the hollow rod 18 is completely thrown out. At this time, the cover 3 is no longer impacted by the water flow from the inside of the hollow rod 18, so that the cover 3 will block the end of the hollow rod 18 under the tension of the elastic rope 32, making it difficult for the stirred reaction material in the mixing barrel 1 to flow into the inside of the hollow rod 18, and after the device stops stirring, there will be almost no solution residue in the hollow rod 18. As the hollow shaft 13 rotates, the multiple spoilers 41 will rotate synchronously, thereby stirring the reactants in the mixing barrel 1 and disturbing the reaction. The flow plate 41 will rotate due to the impact of the water flow, disrupting the passing water flow, so that the reactants in the mixing barrel 1 can be fully mixed. When the lower end of the hollow shaft 13 is extended into the mixing barrel 1 through the operation of the lifting component 12, the dust cover 51 will enter the mixing barrel 1, thereby blocking the top of the mixing barrel 1. As the dust cover 51 descends, the bottom of the capsule 61 will fit tightly with the top of the fixing ring 6. After the solution is filled through the feeding hopper 17, the cover plate 7 is rotated to close the top of the feeding hopper 17. At the same time, a pair of magnets 71 will attract each other. When the slide 21 slides along the middle of the fixed rod 2, the presence of the through groove 8 allows the solution or air in the mixing barrel 1 to easily enter the inside of the fixed rod 2.Reduce the occurrence of the sliding difficulty of the slide tube 21 caused by the pressure inside the fixed rod 2.
