Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel apparatus for the synthesis of piperazine ferulic acid. Background Technology

[0002] Piperazine ferulate is an organic compound, belonging to the piperazine derivatives, which is synthesized by chemical reaction of ferulic acid and piperazine. Piperazine ferulate has certain pharmacological activities and can be used as a drug or drug intermediate in the pharmaceutical field. The preparation of piperazine ferulate requires a reaction vessel.

[0003] When preparing piperazine ferulate via a reaction vessel, it is necessary to prepare the raw materials for piperazine ferulate, as well as other catalysts, solvents, and other auxiliary chemicals. During preparation, the raw materials and catalysts are added to the reaction vessel according to the specified steps. The mixture is stirred by the stirring device inside the reaction vessel, and the reaction vessel is heated to a suitable temperature to complete the reaction under the specified temperature and pressure. After the reaction is completed, cooling, filtration, and washing steps are required to separate the target product and by-products. Finally, the product is purified by crystallization or other methods to obtain the specified piperazine ferulate.

[0004] In existing reactors for preparing piperazine ferulate, the blade angle of the stirring device inside the reactor is fixed. However, the preparation of piperazine ferulate requires the addition of different raw materials and catalysts in batches. This means that the viscosity of the material inside the reactor is not fixed, and the non-adjustable blades have different stirring effects for materials of different viscosities, which requires extending the stirring time and makes it inconvenient to use.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This is the first embodiment of the present invention. This embodiment provides a reactor device for the synthesis of piperazine ferulic acid, including a tank 1, a stirring assembly 4 and a feeding assembly 5 inside the tank 1.

[0034] The stirring assembly 4 includes a rotating shaft 401 that is inserted inside the tank 1. Several stirring blades 402 are provided on the outer surface of the rotating shaft 401. A clamping block 405 is fixedly connected to one end of the stirring blades 402 near the rotating shaft 401. A transmission block 407 is fixedly connected to one end of the clamping block 405 near the rotating shaft 401. A driven bevel gear 406 is fixedly connected to the outer surface of the transmission block 407. A transmission shaft 403 is provided inside the rotating shaft 401. A transmission bevel gear 408 is provided on the outer surface of the transmission shaft 403.

[0035] Specifically, a motor 2 is installed on the top of the tank 1, and the output end of the motor 2 is fixedly connected to the outer surface of the rotating shaft 401. A feed inlet 3 is installed on the outer surface of the top of the tank 1, and a discharge outlet 6 is installed at the bottom of the tank 1.

[0036] Specifically, the outer surface of the rotating shaft 401 is provided with a circular hole that mates with the clamping block 405. The inside of the circular hole is provided with an insertion hole that mates with the transmission block 407. One end of the transmission block 407 is inserted into the interior of the rotating shaft 401 through the insertion hole and is fixedly connected to the driven bevel gear 406. The clamping block 405 is movably connected inside the circular hole. The circular hole on the outer surface of the rotating shaft 401 allows the clamping block 405 to be movably installed inside the circular hole, so that when the transmission block 407 and the driven bevel gear 406 rotate with the transmission bevel gear 408, the transmission block 407 can drive the stirring blade 402 to rotate through the clamping block 405.

[0037] Specifically, a filling block 404 is fixedly connected to the outer surface of the drive shaft 403, and a cavity is provided inside the rotating shaft 401. The filling block 404 fits against the inner wall of the cavity. Through the cooperation between the filling block 404 and the inner wall of the rotating shaft 401, the stability of the drive shaft 403 is maintained, and the drive shaft 403 itself is prevented from shaking during the stirring process.

[0038] Specifically, a mating block 411 is fixedly connected to the top of the drive shaft 403, and a telescopic cylinder 410 is slidably connected to the top outer surface of the rotating shaft 401. A flat key is provided on the inner side of the telescopic cylinder 410 and the outer surface of the mating block 411. Several keyways are provided on the inner side of the telescopic cylinder 410 that mate with the flat key on the outer surface of the mating block 411. A keyway is provided on the top outer surface of the rotating shaft 401 that mates with the flat key on the inner side of the telescopic cylinder 410. The flat key on the inner side of the telescopic cylinder 410 mates with the keyway on the top of the rotating shaft 401. Thus, the relative rotation of the drive shaft 403 and the rotating shaft 401 is achieved through the engagement of the keyway on the inner side of the telescopic cylinder 410 with the flat key on the outer surface of the mating block 411.

[0039] Specifically, nuts are fixedly connected to the top outer surface of the rotating shaft 401 and the top of the mating block 411. A spring 409 is fixedly connected between the nut on the outer surface of the rotating shaft 401 and the telescopic tube 410. When adjusting, the nut on the outer surface of the rotating shaft 401 needs to be held to prevent the rotating shaft 401 from rotating during the adjustment process. The spring 409 allows the telescopic tube to return to its original position after the telescopic block is released, thus engaging with the mating block 411.

[0040] Furthermore, pressing down on the telescopic cylinder 410 compresses the spring 409, causing the keyway on the inner side of the telescopic cylinder 410 to disengage from the flat key on the outer surface of the mating block 411, thus unlocking the mating block 411. Then, rotating the nut on the top of the mating block 411 causes the transmission shaft 403 to rotate, which in turn drives the active bevel gear on the outer surface to rotate. The active bevel gear then drives the driven bevel gear 406 to rotate, which in turn drives the stirring blade 402 to tilt via the transmission block 407 and the clamping block 405. This adjusts the angle of the stirring blade 402, allowing it to stir a wider area for materials with higher viscosity and a narrower area for materials with lower viscosity, thus improving the stirring effect.

[0041] Example 2

[0042] Reference Figure 1 , Figure 2 and Figure 7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The feeding assembly 5 includes a material tray 501 that is movably disposed inside the tank body 1. A first guide plate 503 is fixedly connected to the lower surface of the material tray 501. A plurality of connecting plates 506 are fixedly connected to the lower surface of the first guide plate 503. A second guide plate 505 is fixedly connected to the lower surface of the connecting plate 506. A connecting disk 504 is fixedly connected to the upper surface of the second guide plate 505. The connecting disk 504 is fixedly installed on the outer surface of the rotating shaft 401.

[0043] Specifically, the upper surface of the material tray 501 is provided with several raised strips, which are spirally distributed on the inner side of the material tray 501. The cross-sections of the first guide plate 503 and the second guide plate 505 are both conical. By setting the raised strips, the speed at which the material falls into the tank 1 is slowed down. There are gaps between adjacent raised strips, so that as the material tray 501 rotates, the material can gradually fall through the spirally distributed raised blocks to the first guide plate 503 and the second guide plate 505 below, thereby achieving uniform feeding and avoiding local high concentration caused by fixed material addition position.

[0044] Specifically, a fixing ring 502 is fixedly connected to the top of the inner cavity of the tank body 1. The outer surface of the fixing ring 502 is provided with an inclined surface that matches the outer surface of the material tray 501. The outer surface of the material tray 501 abuts against the fixing ring 502. The fixing ring 502 helps to support the material tray 501, so that the material tray 501 remains stable when it rotates with the rotating shaft 401.

[0045] Furthermore, the rotating shaft 401, through the connection plate 504, the second guide plate 505, the connecting plate 506, and the first guide plate 503, drives the material tray 501 to rotate. When the material tray 501 rotates, it drives the raised strips on the upper surface to rotate, so that the material can be evenly distributed on the material tray 501 as the material tray 501 rotates. Then, it gradually falls onto the first guide plate 503 through the inclined surface of the material tray 501, and then onto the second guide plate 505. Thus, it falls into the tank 1 through the gap between the adjacent connecting plates 506. The setting of the feeding component 5 improves the problem of material accumulation in one place when the material is fed through a single fixed feeding port 3, which causes excessive local concentration and increases the stirring burden, thereby improving the dispersion uniformity.

[0046] Working principle: During the preparation of piperazine ferulate, the stirring component 4 is adjusted according to the required stirring force and the viscosity of the material. This adjustment requires two workers. One worker uses a wrench or other tool to hold the lower nut, stopping the rotating shaft 401. The other worker presses down on the telescopic cylinder 410, compressing the spring 409. This disengages the keyway on the inner side of the telescopic cylinder 410 from the flat key on the outer surface of the mating block 411, unlocking the mating block 411. Then, the nut on top of the mating block 411 is rotated, causing the drive shaft 403 to rotate. The drive shaft 403 then rotates the active bevel gear on its outer surface. The drive shaft 403 rotates via the active bevel gear 406, which in turn drives the driven bevel gear 406 to rotate. This, in turn, drives the stirring blades 402 to tilt via the transmission block 407 and the clamping block 405, thereby adjusting the angle of the stirring blades 402. This allows the stirring blades 402 to stir over a wider area when dealing with materials of higher viscosity, and over a narrower area when dealing with materials of lower viscosity, thus improving the stirring effect. After rotating the drive shaft 403 to the appropriate angle, the telescopic cylinder 410 is released. Under the reset action of the spring 409, the telescopic cylinder 410 moves upward, causing it to engage with the keyway on its inner side and the flat key on the outer surface of the mating block 411, thereby locking the drive shaft 403. To prevent the transmission shaft 403 from rotating when the rotating shaft 401 drives the stirring blades 402 to rotate under the action of the motor 2, the stirring blades 402 are adjusted. Then, the raw materials and the required catalyst are added to the tank 1 in batches through the feed inlet 3. After the materials are added to the tank 1, they fall into the material tray 501. Then, the motor 2 is started synchronously, and the motor 2 drives the rotating shaft 401 to rotate. The rotating shaft 401, through the setting of the connecting plate 504, the second guide plate 505, the connecting plate 506 and the first guide plate 503, drives the material tray 501 to rotate. When the material tray 501 rotates, it drives the raised strips on the upper surface to rotate, so that the materials can move with the material tray 501. The material is rotated and evenly distributed on the tray 501, then gradually falls onto the first guide plate 503 through the inclined surface of the tray 501, and then onto the second guide plate 505. It then falls into the tank 1 through the gap between the adjacent connecting plates 506. The feeding component 5 improves the problem of material accumulation in one place when the material is added through a single fixed feed port 3, which would cause excessive local concentration and increase the stirring burden. It also improves the uniformity of dispersion. After the material is added, catalysts or other chemical agents need to be added in batches. When adding them, the motor 2 needs to be stopped, and the stirring component 4 needs to be adjusted again according to the viscosity of the material inside the tank 1. Finally, the preparation of piperazine ferulate is completed.
