Description

Technical Field

[0003] After retrieval, the Chinese utility model application number is 202210702129.1, and the patent document name is a rapid cooling device for pharmaceutical intermediates, including a U-shaped frame. Support legs are fixedly connected to the four corners of the bottom of the U-shaped frame. L-shaped plates are fixedly connected to the front and rear side walls of the U-shaped frame, and a top plate is fixedly connected to the tops of the two L-shaped plates. A fixed frame is slidably connected inside the U-shaped frame. A push plate is fixedly connected to the left side of the bottom of the fixed frame, and the bottom of the push plate is slidably connected to the bottom cavity of the U-shaped frame;

[0004] When the above patent document cools down the pharmaceutical intermediate, the first motor drives the first rotating rod and the stirring rod to rotate to stir the pharmaceutical intermediate in the reaction tank, and at the same time, the cold air blower is turned on to cool down the pharmaceutical intermediate in the reaction tank.

[0030] Embodiment 1

[0031] To solve the technical problems in the background art, the following is a rapid cooling device for pharmaceutical intermediates:

[0032] Combined with Figures 1-6As shown in the figure, a rapid cooling device for a pharmaceutical intermediate provided by the present invention includes a tank body 1. A conical cylinder 4 is fixedly connected and communicated at the bottom end of the tank body 1. A feed pipe 8 is fixedly arranged through the top surface of the tank body 1. A feed outer expansion pipe 7 is fixedly connected and communicated at the top end of the feed pipe 8. A discharge pipe 5 is fixedly arranged through the bottom end of the conical cylinder 4. An installation valve 16 is installed on the discharge pipe 5. A plurality of support legs 3 are uniformly and fixedly arranged on the conical cylinder 4. The arrangement of the plurality of support legs 3 increases the practicability of the overall device. A protective housing 2 is fixedly sleeved on the tank body 1. A circulating cooling assembly 9 is arranged between the protective housing 2 and the tank body 1;

[0033] A three - head connecting plate 12 is arranged inside the tank body 1. A plurality of U - shaped outer expansion stirring rods 11 are arranged between the tank body 1 and the conical cylinder 4. The top end of each U - shaped outer expansion stirring rod 11 is fixedly connected to the corresponding end of the three - head connecting plate 12. And a plurality of first stirring blades 10 are uniformly and fixedly arranged on each U - shaped outer expansion stirring rod 11. A stirring connecting shaft 15 is arranged between the plurality of U - shaped outer expansion stirring rods 11. A synchronous reverse stirring assembly 6 is arranged between the stirring connecting shaft 15 and the tank body 1. The synchronous reverse stirring assembly 6 is connected to the three - head connecting plate 12.

[0034] A plurality of installation collar rings 14 are uniformly and fixedly sleeved on the part of the stirring connecting shaft 15 located inside the tank body 1. A plurality of second stirring blades 13 are uniformly and fixedly arranged on each installation collar ring 14.

[0035] The circulating cooling assembly 9 includes a hollow installation plate 91. One side of the hollow installation plate 91 is open. One side of the hollow installation plate 91 penetrates through the protective housing 2 and is fixedly connected to the tank body 1. A plurality of annular water - cooling pipes 93 are uniformly installed between the protective housing 2 and the tank body 1. Both ends of each annular water - cooling pipe 93 penetrate through the hollow installation plate 91 and extend into the hollow installation plate 91. A water - cooling circulating pump 94 is fixedly arranged through the hollow installation plate 91. A water - cooling inlet pipe 95 is fixedly connected and communicated at the end of the water - cooling circulating pump 94 at the water - inlet end. The end of the water - cooling inlet pipe 95 far from the water - cooling circulating pump 94 is fixedly arranged through the hollow installation plate 91. A water - cooling drain pipe 92 is fixedly connected and communicated at the end of the water - cooling circulating pump 94 at the water - outlet end. A shunt is fixedly connected and communicated at the end of the water - cooling drain pipe 92 far from the water - cooling circulating pump 94. The shunt is installed inside the hollow installation plate 91. And the water - inlet end of each annular water - cooling pipe 93 is fixedly connected and communicated with the shunt.

[0036] A partition plate 911 is fixedly arranged inside the hollow installation plate 91. The partition plate 911 divides the hollow installation plate 91 into a first water - cooling chamber 912 and a second water - cooling chamber 913. The shunt, the water - cooling drain pipe 92 and one end of the annular water - cooling pipe 93 are all located in the first water - cooling chamber 912. The water - cooling inlet pipe 95 and the other end of the annular water - cooling pipe 93 are all located in the second water - cooling chamber 913.

[0037] In specific use, by adjusting the installation valve 16, the discharge pipe 5 forms a closed pipeline, and then the pharmaceutical intermediate to be cooled is put into the tank body 1 and the conical cylinder 4 through the feed outer expansion pipe 7 and the feed pipe 8. When it is necessary to cool the pharmaceutical intermediate in the tank body 1, the water-cooled circulation pump 94 is started simultaneously. (Cooling liquid is provided in the second water-cooled chamber 913, the diverter, and each annular water-cooled pipe 93.) Driven by the power output of the water-cooled circulation pump 94, the water-cooled inlet pipe 95 drives the cooling liquid in the second water-cooled chamber 913 to be transported into the water-cooled circulation pump 94 and then transported to the diverter through the water-cooled drain pipe 92. Then, the cooling liquid is transported to each annular water-cooled pipe 93 through the diverter, enabling the cooling liquid in several annular water-cooled pipes 93 to circulate. Since each annular water-cooled pipe 93 is arranged between the tank body 1 and the protective housing 2, see Figure 2 , when the cooling liquid in several annular water-cooled pipes 93 circulates, the cooling liquid enters from one end of the annular water-cooled pipe 93 and is discharged from the other end of the annular water-cooled pipe 93 (the cooling liquid is discharged into the second water-cooled chamber 913), and so on. In this way, it is convenient to cool the pharmaceutical intermediate in the tank body 1 through the circulating cooling assembly 9. Compared with the prior art method of using a cold air blower to blow downward to cool the pharmaceutical intermediate in the reaction box, the heat dissipation and cooling efficiency of the circulating cooling assembly 9 is better, which is beneficial to increasing the cooling speed of the overall device and improving the practicality of the overall device.

[0042] In specific use, based on Example 1, when it is necessary to further increase the cooling efficiency and practicality of the overall device, the operation is as follows:

[0043] Start the drive motor 61. Under the power output of the drive motor 61, drive the rotating shaft 62 and the adjusting gear 66 to rotate synchronously. At the same time, under the meshing operation, drive the two end face gear discs 65 to rotate synchronously in the opposite direction. When the two end face gear discs 65 rotate, at the same time, drive each synchronizing gear 67 to rotate synchronously along the two end face gear discs 65 (the synchronizing gear 67 and the adjusting gear 66 rotate in the same direction).

In this way, the pharmaceutical intermediate in the tank body 1 can be mixed and stirred by the stirring coupling shaft 15 and the plurality of second stirring blades 13. At the same time, the lower end face gear disc 65 rotates synchronously. When the lower end face gear disc 65 rotates synchronously, drive the rotating cylinder 63 to rotate synchronously along the tank body 1 and the stirring coupling shaft 15, and then drive the three - headed connecting plate 12, a plurality of U - shaped outward - expanding stirring rods 11 on the three - headed connecting plate 12, and a plurality of first stirring blades 10 on each U - shaped outward - expanding stirring rod 11 to rotate synchronously. (The first stirring blades 10 and the second stirring blades 13 rotate synchronously in the opposite direction, see Figure 2 、 Figure 3 ). At the same time, with the cooperative setting of the circulating cooling component 9, it is convenient to further increase the efficiency of quickly cooling the pharmaceutical intermediate. To sum up, through the cooperative setting of the synchronous reverse stirring component 6 and the driving component, it not only effectively solves the problem in the prior art that when stirring and mixing the pharmaceutical intermediate, only the first motor is used to drive the first rotating rod and the stirring rod to rotate to stir the pharmaceutical intermediate in the reaction tank for subsequent cooling, but also in the design of cooling and cooperating with stirring the pharmaceutical intermediate, through this design, the pharmaceutical intermediate can be stirred by synchronous reverse rotation, which is beneficial to improving the cooling efficiency of the overall device, and thus effectively increases the practicality of the overall device and is convenient for popularization.
