Description

Technical Field

[0001] The present invention belongs to the technical field of machinery, and specifically relates to a reaction device for the production of pinacolone. Background Technique

[0002] Pinacolone is stored in a cool and ventilated warehouse, away from fire sources and heat sources. The warehouse temperature should not exceed 37°C. Pinacolone is used as a solvent and extractant, can be used in organic synthesis, and can also be used to produce agricultural fungicides such as benzylchlorotriazole alcohol, triadimefon, triadimenol, bitertanol, diniconazole, and octhilinone; as well as plant growth regulators such as paclobutrazol, uniconazole, flumetralin, chlormequat chloride, and methylchloroisothiazolinone. Sometimes it can also be used to produce herbicides and pharmaceutical products, and is used as a solvent and laboratory reagent.

[0003] Currently, when people produce pinacolone, they often need to add various solvents and make the solvents react with each other to obtain pinacolone. When adding the required solvents for mixing in the existing device, the feed port often needs to be opened, and the solvents and other raw materials are poured into the reaction cylinder through the feed port to complete the feeding operation. However, since pinacolone is a toxic solvent, when the feed port is opened, a small amount of gas will escape from the feed port, causing people to inhale these toxic gases, thereby threatening people's safety.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] Through the cooperation among structures such as the feed pipe, fixed block, bent hose, and roller, etc., the device has the function of preventing toxic gases inside the reaction cylinder from escaping during feeding. By pulling one end at the top of the feed pipe, the end of the hydrogenation pipe located outside the fixed block is elongated. Subsequently, the solvent bottle is rotated so that the top of the inner cavity of the feed pipe is threadedly connected to the solvent bottle. Then, the operator releases the feed pipe and the feed pipe returns to its original position. At this time, due to the rotation of the central shaft, the roller will also drive the branched block to rotate, so that the end of the roller close to the bent hose rotates counterclockwise. When the two rollers come into contact with and squeeze the bent hose, the solvent between the two rollers in the bent hose will be transported into the inner cavity of the reaction cylinder. At the same time, since the roller squeezes the bent hose, it prevents the gas inside the reaction cylinder from leaking when people replace the solvent bottle, thereby improving the safety of people during use;

[0018] Through the cooperation among structures such as the first gear, second gear, stirring block, and circular plate, etc., the device has the function of stirring the mixed solvent inside the device well. By operating the power motor, the first gear rotates, so that the second gear drives the central shaft to rotate. At this time, the stirring block will rotate along with the central shaft. At the same time, hydrogen is introduced into the hydrogenation pipe. At this time, the hydrogen will enter the inner cavity of the reaction cylinder through the small holes on the central shaft and the stirring block. At the same time, through the limitation of the limiting rod and the cooperation between the circular plate and the central shaft, the circular plate makes a reciprocating motion in the up and down direction, so that the device plays a role in stirring and tumbling the raw materials;

[0019] Through the cooperation among structures such as the piston block, first elastic spring, I-shaped cylinder, and cylinder rod, etc., the device has the function of facilitating people to detect the mixing situation of pinacolone. Through the reciprocating motion of the circular plate in the up and down direction, when the circular plate moves downward, it will squeeze the top of the sealing ring block so that the sealing ring block moves downward. At this time, the second elastic spring is in a compressed state. At the same time, the pinacolone in the inner cavity of the reaction cylinder will enter the inner cavity of the round hole. When the circular plate moves upward, at this time, due to the elastic force of the second elastic spring, the sealing ring block resets and closes the round hole. When people need to observe the mixing situation of pinacolone, at this time, people use the bottom of the inner cavity of the measuring cup to squeeze the bottom of the cylinder rod, so that the cylinder rod squeezes the I-shaped cylinder and the piston block to move upward. At this time, the inside of the round hole is opened, and the pinacolone in the round hole will enter the measuring cup through the inner cavity at the bottom of the central shaft, which is convenient for people to observe.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Such as Figures 1 to 9As shown in the figure, the present invention provides a reaction device for the production of pinacolone, which includes a reaction cylinder 1. A fixed block 2 and a support rod 7 are fixedly connected to the top of the reaction cylinder 1. A winding cylinder 3 is movably connected to the inner cavity of the fixed block 2. An annular spring piece 6 is fixedly connected to the inner cavity of the winding cylinder 3. A feed pipe 4 is wound around the middle part of the outer surface of the winding cylinder 3. A discharge port 5 is fixedly connected to one side of the bottom of the inner cavity of the reaction cylinder 1. A bent hose 8 is fixedly connected to one side of the bottom of the inner cavity of the fixed block 2. A hydrogenation pipe 14 is fixedly connected to the top of the reaction cylinder 1. A central shaft 15 is connected to the bottom of the inner cavity of the hydrogenation pipe 14 through a bearing. A branched block 9 is fixedly connected to the top of the outer surface of the central shaft 15. Rollers 10 are movably connected to the inner cavity of the branched block 9 in an annular and equiangular manner; Pull one end of the top of the feed pipe 4 to extend the end of the hydrogenation pipe 14 located outside the fixed block 2. Then rotate the solvent bottle so that the top of the inner cavity of the feed pipe 4 is threadedly connected to the solvent bottle. Then the operator releases the feed pipe 4 so that the feed pipe 4 returns to its original position. At this time, due to the rotation of the central shaft 15, the rollers 10 will also drive the branched block 9 to rotate, so that the end of the roller 10 close to the bent hose 8 rotates counterclockwise. When the two rollers 10 come into contact with and squeeze the bent hose 8, the solvent in the bent hose 8 between the two rollers 10 will be transported into the inner cavity of the reaction cylinder 1. At the same time, since the rollers 10 squeeze the bent hose 8, it prevents the leakage of the gas inside the reaction cylinder 1 when people replace the solvent bottle, thereby improving the safety of people during use.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown in the figure, a power motor 11 is fixedly connected to one side of the top of the reaction cylinder 1 away from the fixed block 2. A first gear 12 is fixedly connected to the output shaft end of the power motor 11. A second gear 13 is fixedly connected to the top of the outer surface of the central shaft 15. A stirring block 16 is fixedly connected to the middle upper part of the outer surface of the central shaft 15. A circular plate 17 is threadedly connected to the middle part of the outer surface of the central shaft 15. Limit rods 24 are movably connected to the inner cavity of the circular plate 17 in an annular and equiangular manner; By operating the power motor 11, the first gear 12 rotates, so that the second gear 13 drives the central shaft 15 to rotate. At this time, the stirring block 16 will rotate with the central shaft 15. At the same time, hydrogen is introduced into the hydrogenation pipe 14. At this time, the hydrogen will enter the inner cavity of the reaction cylinder 1 through the small holes on the central shaft 15 and the stirring block 16. At the same time, through the limitation of the limit rods 24 and the cooperation between the circular plate 17 and the central shaft 15, the circular plate 17 makes a reciprocating motion in the up and down direction, so that the device plays a role in stirring and tumbling the raw materials.

[0033] As Figure 2 , Figure 4As shown, at the top of the inner cavity at the lower end of the central shaft 15, a first elastic spring 19 is fixedly connected. One end at the bottom of the first elastic spring 19 is fixedly connected with a piston block 18. The inner cavity at the bottom of the piston block 18 is connected to an I-shaped cylinder 20 by a bearing. The inner cavity at the bottom of the central shaft 15 is movably connected with a cylindrical rod 21. The bottom of the outer surface of the central shaft 15 is movably connected with a sealing ring block 22. The bottom of the sealing ring block 22 is fixedly connected with a second elastic spring 23. Through the reciprocating movement of the circular plate 17, when the circular plate 17 moves downward, it will squeeze the top of the sealing ring block 22, causing the sealing ring block 22 to move downward. At this time, the second elastic spring 23 is in a compressed state. At the same time, the pinacolone in the inner cavity of the reaction cylinder 1 will enter the inner cavity of the circular hole. When the circular plate 17 moves upward, due to the elastic force of the second elastic spring 23, the sealing ring block 22 will reset and close the circular hole. When people need to observe the mixing situation of pinacolone, at this time, people use the bottom of the measuring cup inner cavity to squeeze the bottom of the cylindrical rod 21, causing the cylindrical rod 21 to squeeze the I-shaped cylinder 20 and the piston block 18 to move upward. At this time, the inside of the circular hole is opened, and the pinacolone in the circular hole will enter the measuring cup through the inner cavity at the bottom of the central shaft 15, facilitating people's observation.

[0034] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the support rod 7 is located on the side of the fixed block 2 away from the power motor 11. One end at the top of the feed pipe 4 is located outside the fixed block 2. The feed pipe 4 is movably connected with the support rod 7. A threaded groove is opened at the top of the inner cavity of the feed pipe 4. Through the stretchable design of the feed pipe 4, it prevents the situation where the solvent bottle needs to be inverted, resulting in the scattering of the solvent. At the same time, the design of the support rod 7 plays a role in supporting the feed pipe 4 and the solvent bottle.

[0035] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown in the figure, one end at the bottom of the feed pipe 4 is connected to the bent hose 8 through the inner cavity at the bottom of the fixed block 2. The branched block 9 is located in the inner cavity at the top of the reaction cylinder 1, and the roller 10 presses against the bent hose 8. Through the cooperation among the feed pipe 4, the fixed block 2, and the bent hose 8, when people pull the feed pipe 4, the winding cylinder 3 rotates, enabling the bent hose 8 and the feed pipe 4 to remain connected. At the same time, when the roller 10 presses the bent hose 8, the bent hose 8 will be sealed, preventing the toxic gas inside the reaction cylinder 1 from escaping through the bent hose 8.

[0036] As Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown in the figure, the first gear 12 and the second gear 13 are located in the inner cavity at the top of the reaction cylinder 1, and the first gear 12 and the second gear 13 are meshed and connected. The inner cavity of the stirring block 16 is connected to the inner cavity at one end of the top of the central shaft 15. The outer surface of the end of the stirring block 16 away from the central shaft 15 is provided with air holes at equal distances. The top and bottom of the outer surface of the central shaft 15 are respectively connected to the top and bottom of the inner cavity of the reaction cylinder 1 through bearings. Through the cooperation between the first gear 12 and the second gear 13, and at the same time through the design of the air holes, when the stirring block 16 rotates, hydrogen can be injected into the inner cavity of the reaction cylinder 1 through the hydrogenation pipe 14, the central shaft 15, and the stirring block 16, making the pinacolone mix more fully.

[0037] As Figure 2 , Figure 4 As shown in the figure, the piston block 18 is movably connected to the inner cavity of the central shaft 15. Two sides at the bottom of the central shaft 15 are provided with round holes located at the bottom of both sides of the outer surface of the central shaft 15. One end at the top of the cylindrical rod 21 is matched with the I-shaped cylinder 20. The sealing ring block 22 is located outside the round hole. The bottom of the second elastic spring 23 is fixedly connected to the bottom of the inner cavity of the reaction cylinder 1. One end at the top of the sealing ring block 22 is matched with the bottom of the round plate 17. Through the design of the I-shaped cylinder 20, when one end at the top of the cylindrical rod 21 contacts the I-shaped cylinder 20, since the central shaft 15 drives the piston block 18 to rotate at this time, it prevents the situation that the piston block 18 drives the I-shaped cylinder 20 to rotate when people use the measuring cup to receive pinacolone.

[0038] The working principle and usage process of the present invention:

[0039] First, the operator runs the power motor 11. The operation of the power motor 11 will cause the first gear 12 to rotate, which will cause the second gear 13 to drive the central shaft 15 to rotate. At this time, the stirring block 16 will rotate with the central shaft 15. Meanwhile, hydrogen is introduced into the hydrogenation pipe 14. At this time, the hydrogen will enter the inner cavity of the reaction cylinder 1 through the small holes on the central shaft 15 and the stirring block 16. Meanwhile, through the limitation of the limiting rod 24 and the cooperation between the circular plate 17 and the central shaft 15, the circular plate 17 makes a reciprocating motion in the up and down direction, so that the device plays a role in stirring and tumbling the raw materials;

[0040] When the operator needs to add solvent to the reaction cylinder 1, the operator opens the solvent bottle at this time, and at the same time pulls one end at the top of the feed pipe 4 to make the end of the hydrogenation pipe 14 outside the fixed block 2 extend. Then the solvent bottle is rotated so that the top of the inner cavity of the feed pipe 4 is threadedly connected to the solvent bottle. Then the operator loosens the feed pipe 4 to make the feed pipe 4 return to its original position. At this time, due to the rotation of the central shaft 15, the roller 10 will also drive the branched block 9 to rotate, so that the end of the roller 10 close to the bent hose 8 rotates counterclockwise. When the two rollers 10 come into contact with and squeeze the bent hose 8, the solvent in the bent hose 8 between the two rollers 10 will be transported into the inner cavity of the reaction cylinder 1. At the same time, because the roller 10 squeezes the bent hose 8, it prevents the leakage of the gas inside the reaction cylinder 1 when people replace the solvent bottle;

[0041] With the up and down reciprocating motion of the circular plate 17, when the circular plate 17 moves downward, it will squeeze the top of the sealing ring block 22, so that the sealing ring block 22 moves downward. At this time, the second elastic spring 23 is in a compressed state. Meanwhile, the pinacolone in the inner cavity of the reaction cylinder 1 will enter the inner cavity of the round hole. When the circular plate 17 moves upward, at this time, due to the elastic force of the second elastic spring 23, the sealing ring block 22 returns to its original position and closes the round hole. When people need to observe the mixing situation of pinacolone, at this time, people use the bottom of the inner cavity of the measuring cup to squeeze the bottom of the cylindrical rod 21, so that the cylindrical rod 21 squeezes the I-shaped cylinder 20 and the piston block 18 to move upward. At this time, the inside of the round hole is opened, and the pinacolone in the round hole will enter the measuring cup through the inner cavity at the bottom of the central shaft 15, which is convenient for people to observe.
