Description

Technical Field

[0001] The utility model relates to the technical field of rotary evaporators, in particular to a rotary evaporator used for the production of alanyl-glutamine. Background Art

[0002] Alanyl-glutamine is an organic compound and an important component of parenteral nutrition. It is mainly used to supplement glutamine and is suitable for patients with catabolism and hypermetabolic conditions. It can promote protein synthesis, maintain the intestinal mucosal barrier, regulate immune response and protect the liver. Alanyl-glutamine requires the use of a rotary evaporator during the production process.

[0003] In the prior art, a Chinese patent with publication number CN217041350U provides a rotary evaporator, the purpose of which is to solve the problem in the prior art that the collecting bottle is easily damaged during use and the condensate flows back. A rotary evaporator is provided, including a rotary evaporator body and a collecting bottle installed on the rotary evaporator body, and the rotary evaporator further includes: a first connecting tube, one end of which is connected to the bottle mouth of the collecting bottle; a second connecting tube, which is sleeved on the outside of the liquid outlet of the condenser tube of the rotary evaporator body and is threadedly connected to the first connecting tube; a plurality of one-way valves, one end of which is annularly distributed on the second connecting tube close to the end of the first connecting tube, and the other end is radially retracted toward the first connecting tube; a tray, the top of which has a lifting groove for lifting the collecting bottle; and a lifting bracket, which is connected to the bottom of the tray. The utility model prevents the coolant from flowing back by setting a one-way valve, uses a threaded connection to increase the firmness of the connection between the collecting bottle and the cooling tube, and sets a tray and a lifting bracket for further support.

[0004] However, in actual use, the above solution still has some shortcomings. The size of the evaporating flask needs to be changed according to actual conditions. When the evaporating flask enters the water level inside the water bath, due to the angle problem, the operator needs to observe the position of the evaporating flask entering the water bath and then stop lifting. During this process, the bottle mouth of the evaporating flask is likely to collide with the edge of the water bath, resulting in loosening of the connection position of the evaporating flask and damage to the evaporating flask. In addition, the distillation area has no corresponding protection, which will affect the evaporation efficiency in the case of air convection. In addition, the motor will vibrate when driving the evaporating flask to rotate, thereby affecting the connection between the transmission tube, the condenser and the evaporating flask, which is easy to loosen and cause unnecessary losses.

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1, as Figures 1 to 6As shown, a rotary evaporator for the production of alanyl-glutamine comprises a base 1, a water bath 2 is fixedly mounted on the top of the base 1, a protective cover 3 is hinged on the right side of the water bath 2, a support base 4 is fixedly mounted on the top of the base 1 and is located on the left side of the water bath 2, a lifting assembly is fixedly mounted inside the support base 4, a rotator 5 is fixedly mounted on the front side of the lifting assembly, a transfer pipe 6 is fixedly mounted inside the rotator 5, an evaporating flask 7 located inside the water bath 2 is fixedly connected to the right side of the transfer pipe 6, a condenser 8 is fixedly connected to the left side of the transfer pipe 6, a support plate 9 is fixedly mounted on the top of the support base 4, and a first A damping spring telescopic rod 10, a second damping spring telescopic rod 11 located on the right side of the first damping spring telescopic rod 10 is fixedly installed on the top of the support plate 9, and a connecting block 12 is fixedly installed on the top of the telescopic end of the first damping spring telescopic rod 10 and the second damping spring telescopic rod 11. The inside of the two connecting blocks 12 are both rotatably installed with a buffer plate 13 whose support surface is in contact with the outside of the transmission tube 6. An auxiliary sleeve 14 is provided on the outside of the connection between the transmission tube 6 and the evaporating flask 7, and a sensing block 15 is fixedly installed on the bottom of the auxiliary sleeve 14. A U-shaped seat 16 is fixedly installed on the top of the water bath 2, and an induction sensor 17 is fixedly installed inside the U-shaped seat 16.

[0023] During the use of the rotary evaporator, the evaporating flask 7 on the right side of the transmission tube 6 is driven to rotate by the rotator 5. During the rotation, the buffer plate 13 on the top of the first damping spring telescopic rod 10 and the second damping spring telescopic rod 11 supports the bottom of the transmission tube 6 to reduce the impact of vibration. When the height is adjusted by the lifting assembly, when the sensing block 15 at the bottom of the auxiliary sleeve 14 drops to the sensing sensor 17, the lifting assembly stops running to prevent the bottle mouth of the evaporating flask 7 from colliding with the edge of the water bath 2 during the descending process.

[0024] Example 2: This example is a further improvement based on Example 1. The details are as follows: the protective cover 3 is U-shaped and transparent.

[0025] The U-shaped protective cover 3 can better protect the outside of the water bath 2, not only reducing air convection, but also preventing the operator from accidentally affecting the evaporating flask 7 in the water bath 2 during the operation of the water bath 2. The transparent protective cover 3 makes it easier for the operator to observe the working status of the water bath 2.

[0026] Example 3: This example is a further improvement on Example 1, and its details are as follows: a mounting groove 18 is provided inside the support seat 4 .

[0027] The installation of the lifting assembly is facilitated by providing the installation slot 18 .

[0028] Example 4. This example is a further improvement based on Example 3, and is specifically as follows: the lifting assembly includes a motor 19, a transmission rod 20 and a lifting cover 21. The motor 19 is fixedly mounted on the top of the base 1. The front side of the output shaft of the motor 19 is fixedly connected to a worm 22 rotatably mounted on the inner wall of the mounting groove 18. A support block 23 is fixedly mounted inside the mounting groove 18. The bottom of the transmission rod 20 is rotatably mounted on the bottom of the mounting groove 18. The top of the transmission rod 20 is fixedly mounted with a threaded rod 24 rotatably mounted on the top of the inner wall of the support block 23. A worm wheel 25 meshing with the worm 22 is fixedly mounted on the outer side of the transmission rod 20. The outer side of the threaded rod 24 is threadedly connected to a moving block 26. The left and right sides of the moving block 26 are fixedly mounted with connecting plates 27 fixedly connected to the left and right sides of the inner wall of the lifting cover 21.

[0029] The motor 19 drives the worm 22 to rotate, thereby driving the worm wheel 25 to rotate, and the threaded rod 24 to rotate through the transmission rod 20, so that the moving block 26 moves up and down under the action of the threaded transmission connection, thereby driving the lifting cover 21 to move up and down through two connecting plates 27 of different lengths, thereby driving the rotator 5 to move up and down, causing the transfer tube 6, evaporating flask 7 and condenser 8 to move up and down.

[0030] Example 5: This example is a further improvement based on Example 4, and its details are as follows: the lifting cover 21 is slidably connected to the inside of the installation groove 18, and the inside of the lifting cover 21 is slidably connected to the outside of the support block 23.

[0031] The lifting cover 21 is made more stable during the process of moving up and down.

[0032] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
