Technical Field

[0001] This utility model belongs to the field of pharmaceutical production technology, specifically a drying device for the preparation of sitagliptin phosphate. Background Technology

[0002] Sitagliptin phosphate is a drug used to treat diabetes and is widely used in clinical treatment. The drying equipment involved in its preparation process is crucial to the stability and quality of the drug.

[0003] Currently, when drying sitagliptin phosphate, it is necessary to place it in a special drying device. However, after drying sitagliptin phosphate, the existing device often requires manual removal of the drug from the drying device, which is time-consuming and laborious. In addition, the drug may stick together during the drying process, resulting in poor drying effect and affecting the drug's efficacy. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a drying device for the preparation of sitagliptin phosphate, which solves the problem that currently, when drying sitagliptin phosphate, it is necessary to place it in a special drying device. However, after the existing device has dried sitagliptin phosphate, it is often necessary to manually remove the drug from the drying device, which is time-consuming and laborious. At the same time, during the process of placing the drug in the drying device, the drug may stick together, resulting in poor drying effect and thus affecting the efficacy of the drug.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drying device for the preparation of sitagliptin phosphate, comprising a base, a drying chamber mounted on the base, a conveyor belt inside the drying chamber, a plurality of air holes on the conveyor belt, a plurality of rotating rollers mounted inside the conveyor belt, the two ends of the rotating rollers being connected to the interior of the drying chamber, a rotating shaft mounted on one end of the rotating roller inside the conveyor belt, a motor connected to one end of the rotating shaft passing through the drying chamber, a blower box mounted on the base, a plurality of air outlets inside the blower box, and a plurality of heating wires above the blower box.

[0006] As a further embodiment of this utility model: a support block is installed on the drying box, the support block is connected to the lower part of the second motor, and a guide plate is installed on the drying box.

[0007] As a further embodiment of this utility model: a protective cover is installed on the drying oven, and a motor is installed on the protective cover.

[0008] As a further embodiment of this utility model: a grooved wheel is connected to the output shaft of the motor, and a belt is provided on the grooved wheel.

[0009] As a further embodiment of this utility model: a rotating rod is connected to the grooved wheel, and a conveying blade is installed on the rotating rod.

[0010] As a further embodiment of this utility model: the drying oven is provided with a discharge port, and an inclined plate is installed inside the discharge port.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This drying device for the preparation of sitagliptin phosphate comprises a conveyor belt, a second motor, a rotating shaft, and heating wires. During operation, the output shaft of the second motor drives the rotating shaft connected to it to rotate, which in turn drives the rotating rollers to rotate. The rotation of the rotating rollers connected to the rotating shaft drives the other rotating rollers on the conveyor belt to rotate, thereby driving the conveyor belt to rotate. Simultaneously, the bellows installed on the base operates, and the air generated by the bellows moves upward through the air outlet. The air is heated by the heating wire to form hot air, which moves upward and passes through the air holes opened on the conveyor belt to dry the medicine on the conveyor belt. The rotation of the conveyor belt moves the dried medicine to the discharge port, where the medicine slides off the inclined plate, facilitating subsequent collection and saving time and effort for the staff.

[0013] 2. This drying device for the preparation of sitagliptin phosphate consists of a guide plate, a motor, a rotating rod, and conveyor blades. During operation, the motor is turned on, and its output shaft drives a connected pulley to rotate. The pulley drives a belt, which in turn drives a pulley not connected to the motor to rotate, thus rotating the rotating rod. The rotating rod then drives the conveyor blades mounted on it to rotate. The medicine to be dried is then poured into the drying chamber through the guide plate. The medicine is dispersed by the conveyor blades and falls onto the conveyor belt, facilitating subsequent drying and preventing the medicine from sticking together and causing incomplete drying.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a drying device for the preparation of sitagliptin phosphate, including a base 1, a drying chamber 2 installed on the base 1, a discharge port 3 on the drying chamber 2, and an inclined plate 4 installed inside the discharge port 3. Because of the inclined plate 4, the dried medicine can slide down automatically, saving the time and effort of the staff.

[0021] A support block 20 is installed on the drying oven 2. The support block 20 is connected to the bottom of the motor 13. A guide plate 7 is installed on the drying oven 2. The installation of the guide plate 7 can prevent the medicine from scattering when pouring the medicine and prevent the medicine from being wasted.

[0022] The drying oven 2 is equipped with a protective cover 5, and a motor 6 is installed on the protective cover 5. The protective cover 5 prevents impurities from entering and interfering with the belt 8 and pulley 9, thus ensuring normal operation.

[0023] A grooved wheel 9 is connected to the output shaft of motor 6, and a belt 8 is provided on the grooved wheel 9.

[0024] A rotating rod 10 is connected to the grooved wheel 9, and a conveying blade 11 is installed on the rotating rod 10. Because of the installation of the conveying blade 11, the incoming medicine can be dispersed to prevent the medicine from sticking together.

[0025] The drying chamber 2 is equipped with a conveyor belt 15, which has several air holes 16. The presence of air holes 16 allows the medicine to be fully dried, thus improving the drying efficiency of the medicine.

[0026] Several rotating rollers 14 are installed inside the conveyor belt 15. The two ends of the rotating rollers 14 are connected to the inside of the drying chamber 2. A rotating shaft 12 is installed on one end of the rotating roller 14 inside the conveyor belt 15. One end of the rotating shaft 12 passes through the drying chamber 2 and is connected to a motor 13. A blower box 17 is installed on the base 1. Several air outlets 18 are provided inside the blower box 17. Several heating wires 19 are provided above the blower box 17.

[0027] The working principle of this utility model is as follows: During operation, motor 6 is turned on, and the output shaft of motor 6 drives the connected pulley 9 to rotate. The pulley 9 drives the belt 8 to rotate, and the belt 8 drives the pulley 9 not connected to motor 6 to rotate, thereby driving the rotating rod 10 to rotate. The rotation of the rotating rod 10 drives the conveyor blades 11 mounted on it to rotate. Then, the medicine to be dried is poured into the drying chamber 2 through the guide plate 7. The medicine is broken up by the conveyor blades 11 and then falls onto the conveyor belt 15. Then, the output shaft of motor 13 drives the connected rotating shaft 12 to rotate. The rotating shaft 12 drives the rotating roller 14 to rotate. The rotation of the rotating roller 14 connected to the rotating shaft 12 drives the other rotating rollers 14 on the conveyor belt 15 to rotate, thereby driving the conveyor belt 15 to rotate. At the same time, the bellows 17 installed on the base 1 works. The air generated by the bellows 17 moves upward through the air outlet 18. The air is heated by the heating wire 19 to form hot air. The hot air moves upward and passes through the air holes 16 opened on the conveyor belt 15 to dry the medicine on the conveyor belt 15. The rotation of the conveyor belt 15 will move the dried medicine to the discharge port 3, and the medicine will then slide off the inclined plate 4.
