[0002] In the pharmaceutical production process, it is often necessary to dissolve the active ingredients in the raw materials in liquid solvents before manufacturing. Pharmaceutical separation equipment is an indispensable piece of equipment in the pharmaceutical industry. Its main function is to extract, separate and purify target components from complex mixtures to ensure the quality, safety and efficacy of drugs.

[0003] Current pharmaceutical separation devices often suffer from several drawbacks during operation. Firstly, the temperature control of the separated drugs during the feeding and separation process is difficult, making it challenging to achieve optimal reaction conditions and thus reducing separation efficiency. Secondly, the separation membrane is difficult to replace according to the required separation degree, further diminishing the flexibility and practicality of the equipment. Therefore, those skilled in the art have developed a pharmaceutical separation device to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pharmaceutical separation device. Through the design of a heat exchange feeding device, the feeding rate can be adjusted according to the operator's requirements, and it possesses high heat transfer efficiency, enabling rapid temperature adjustment during the separation process to ensure optimal reaction conditions and thus improve separation efficiency. Furthermore, the fixed sealing device facilitates quick installation and removal of the sealing cap and cleaning of the separation tank, reducing the difficulty of cleaning the tank and effectively compressing the sealing ring, thereby improving ease of installation and removal and sealing performance. Finally, the connecting device allows for detachable connection between the two circular frames and the first and second connecting rods, enabling the replacement of the separation membrane according to the required degree of drug separation, thus improving the flexibility and practicality of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pharmaceutical separation device, comprising a separation tank and a controller, wherein the controller is located at the center of the front end face of the separation tank, three supporting legs are arranged in a triangular pattern at the center of the lower end face of the separation tank, a first circular groove is provided at the center of the upper end face of the separation tank, a sealing cover is fitted at the center of the lower inner wall of the first circular groove, a feed inlet is provided at the center of the upper end face of the sealing cover, a heat exchange feed device is provided at the center of the feed inlet, a fixing sealing device is provided at the center of the lower inner wall of the first circular groove, a circular groove is provided at the center of the inner wall of the separation tank, a circular frame is provided at the center of the inner side of the circular groove and at the lower part of the inner side of the circular groove, a separation membrane is provided at the lower part of the inner side of the inner side of the two circular frames, four first connecting rods are arranged in a circular pattern between the sealing cover and the upper circular frame, four second connecting rods are arranged in a circular pattern at the center of the two circular frames, four connecting devices are arranged in a circular pattern at the centers of the upper and lower end faces of the two circular frames, and a discharge port is provided at the center of the lower inner wall of the separation tank;

[0006] The above technical solution, through the setting of the heat exchange feeding device, enables the feeding rate to be adjusted according to the feeding requirements of the staff, and has high heat transfer efficiency, which can quickly adjust the temperature in the separation process, ensure that the reaction conditions are in the best state, and thus improve the separation efficiency.

[0007] Furthermore, the heat exchange feeding device includes two fixed rods, a rotating rod, a metal spiral plate rotary motor, two heaters, and a temperature sensor. The two fixed rods are respectively located at the upper and lower center of the inside of the feed inlet. The rotating rod is located between the two fixed rods, and its two ends are rotatably connected to the two fixed rods via bearings. The lower end of the rotating rod passes through the upper end face of the lower fixed rod and extends to the lower end face of the lower fixed rod. The metal spiral plate is located at the center of the outer side of the rotating rod. The rotary motor is located at the lower end of the center of one side of the feed inlet, and its output end passes through one side wall of the feed inlet and extends to one inner side wall of the feed inlet. The two heaters are respectively located at the center of the two inner side walls of the feed inlet. The temperature sensor is located at the center of the lower end face of the upper fixed rod.

[0008] The above technical solution uses a fixed rod to support the rotating rod, which in turn drives the metal spiral plate to rotate, allowing the feeding rate to be adjusted according to the worker's feeding requirements. The metal spiral plate is then heated by a heater, which provides efficient heat transfer, enabling rapid temperature regulation during the separation process. Furthermore, the temperature sensor ensures that the reaction conditions are at their optimal state, thereby improving separation efficiency.

[0009] Furthermore, a first transmission wheel is provided at the lower center of the outer side of the rotating rod, and a second transmission wheel is provided at the outer side of the output end of the rotary motor, with the first transmission wheel and the second transmission wheel meshing with each other;

[0010] The above technical solution controls the start of the rotary motor by the controller, which drives the second transmission wheel to rotate. The second transmission wheel meshes with the first transmission wheel, allowing the second transmission wheel to drive the first transmission wheel to rotate. The first transmission wheel then drives the rotating rod to rotate, thus satisfying the requirements for rotating the rod.

[0011] Furthermore, the fixed sealing device includes two air pumps, two connecting pipes, an annular suction cup, and two sealing rings. The two air pumps are respectively located at the upper center of both sides of the separation tank. The two connecting pipes are respectively located at the output ends of the two air pumps.

The output ends of the two connecting pipes pass through the lower end face of the annular suction cup and extend to the lower inner wall of the annular suction cup. The two sealing rings are respectively located at the inner and outer sides of the center of the upper end face of the annular suction cup.

[0012] The above technical solution uses a controller to start the air pump, which in turn generates negative pressure inside the annular suction cup via a connecting pipe. This ensures a tight seal between the suction cup and the sealing cap, facilitating quick installation and removal of the sealing cap and rinsing of the inside of the separation tank. This reduces the difficulty of rinsing the inside of the separation tank. Furthermore, the sealing ring effectively prevents gas leakage and ensures the stability and durability of the seal.

[0013] Furthermore, the plurality of connecting devices include a plurality of second circular grooves, a plurality of bolts, a plurality of slots, and a plurality of threaded holes. The plurality of second circular grooves are arranged in a circular pattern at the upper and lower center of the outer side of the two circular frames. The plurality of bolts are respectively disposed inside the plurality of second circular grooves. The plurality of slots are arranged in a circular pattern at the center of the upper and lower end faces of the two circular frames and are respectively sleeved and connected to the lower ends of the four first connecting rods and the two ends of the four second connecting rods. The plurality of threaded holes are respectively disposed on the inner sidewall of the plurality of slots and are respectively threaded and sleeved between the plurality of second circular grooves. The plurality of bolts pass through the plurality of slots, the lower ends of the four first connecting rods, and the two ends of the four second connecting rods in sequence and extend into the plurality of threaded holes.

[0014] Through the above technical solution, the first and second connecting rods are sleeved inside the slot, and then bolts are used to pass through them. The bolts are then threaded into the threaded holes, which allows for the detachable fixing of the two circular frames to the first and second connecting rods. This enables the separation membrane to be replaced according to the required degree of drug separation, thereby improving the flexibility and practicality of the equipment. Furthermore, the bolts are sleeved inside the second circular groove to prevent protrusions from forming on the outside of the circular frame, which could affect the instability of its sliding between the frame and the circular groove.

[0015] Furthermore, the upper ends of the four first connecting rods are respectively connected to the lower end face of the sealing cover by a threaded rotation;

[0016] The above technical solution achieves a fixed connection between the first connecting rod and the sealing cover by means of a threaded rotational connection, and also ensures that the sealing cover can drive the circular frame to slide out of the separation tank.

[0035] Working Principle: In the pharmaceutical separation device, the medicine to be separated is placed into the separation tank 1 through the feed inlet 5. Then, the controller 2 controls the rotary motor 605 to start, which drives the second transmission wheel 606 to rotate. The second transmission wheel 606 meshes with the first transmission wheel 604, allowing the second transmission wheel 606 to drive the first transmission wheel 604 to rotate.

[0036] Then, the medicine is separated by the separation membrane 10 inside the annular frame 9, and then conveyed out of the separation tank 1 through the discharge port 14. The controller 2 controls the air pump 701 to start, and the connecting pipe 702 can generate negative pressure inside the annular suction cup 703, so that it can fit tightly with the sealing cover 4 inside the first circular groove 15. This makes it convenient for the staff to quickly install and remove the sealing cover 4 and rinse the inside of the separation tank 1, reducing the difficulty of rinsing the inside of the separation tank 1. The sealing ring 704 can effectively prevent gas leakage and ensure the stability and durability of the seal. Then, the first connecting rod 11 and the second connecting rod 12 are sleeved inside the slot 1303, and then bolts 1302 are used to secure the seal. The device is perforated and then threadedly connected to the threaded hole 1304 via bolt 1302, which allows for detachable fixing of the two annular frames 9 to the first connecting rod 11 and the second connecting rod 12. This enables the separation membrane 10 to be replaced according to the required degree of drug separation, thereby improving the flexibility and practicality of the equipment. Bolt 1302 is then fitted inside the second circular groove 1301 to prevent protrusions from forming on the outside of the annular frame 9, which could affect the instability of its sliding with the annular groove 8. Finally, the first connecting rod 11 is threadedly rotated to connect with the sealing cover 4, which ensures a fixed connection between the first connecting rod 11 and the sealing cover 4, and also allows the sealing cover 4 to drive the annular frame 9 to slide out of the separation tank 1 for replacement.
