Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical concentration devices, and in particular to a pharmaceutical concentration device. Background Technology

[0002] Drugs refer to substances used to prevent, treat, or diagnose human diseases, or to purposefully regulate human physiological functions, and which have specified indications or functions, usage, and dosage. This includes traditional Chinese medicine, chemical drugs, and biological products. Concentration refers to increasing the concentration of a solution by evaporating the solvent through methods such as heating; more broadly, it refers to reducing the unwanted components of an object through certain methods, thereby increasing the relative content of the desired components.

[0003] Chinese Patent Publication No. CN222195920U discloses a concentration device for pharmaceutical production, including a concentration tank. A gear ring is rotatably connected to the upper inside of the concentration tank, and a rotating ring is rotatably connected to the lower inside of the concentration tank. A second scraper is fixedly connected to the bottom of the rotating ring. A first scraper is provided inside the concentration tank, and a stirring rod is fixedly connected to the side of the first scraper. An electric motor is installed on the top of the concentration tank, and a gear is installed at the bottom of the electric motor.

[0004] In this existing design, although the motor can rotate the gears and the gear ring, and the gear ring, the first scraper, the rotating ring, the second scraper and the first scraper are a whole and rotate together, the stirring rod also rotates when the first scraper rotates, stirring the medicine. The concentrated medicine flows out from the outlet. When the first scraper rotates, it scrapes off the medicine remaining on the inner wall side, and when the second scraper rotates, it scrapes off the medicine remaining on the inner wall bottom, avoiding the residue inside the concentration tank. However, the heater directly heats the concentration tank, and the heat generated is only used for the concentration process, which does not make full use of the residual heat, resulting in energy waste. In addition, the medicine enters the concentration tank directly from the feed inlet without preheating treatment, which can easily lead to a long concentration time and low efficiency.

[0005] Therefore, a drug concentration device is designed to solve the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a pharmaceutical concentration device that features preheating of pharmaceuticals, improved energy utilization efficiency, and shortened concentration time.

[0010] In a preferred embodiment of the pharmaceutical concentration device of this utility model, the surface of the double-layer heat exchange tube is connected to a connecting pipe, one end of which is connected to the preheating chamber, and the other end of which is connected to the gas guide pipe.

[0011] As a preferred embodiment of the pharmaceutical concentration device of this utility model, the inner wall of the preheating chamber is equipped with fins, and the number of fins is several, with the several fins evenly distributed on the inner wall of the preheating chamber.

[0012] As a preferred embodiment of the pharmaceutical concentration device of this utility model, the guide plate is spiral in shape.

[0013] As a preferred embodiment of the pharmaceutical concentration device of this utility model, the top surface of the base is provided with a groove, a positioning block is fixedly installed inside the groove, the bottom surface of the receiving hopper is provided with a positioning groove, and a clamping plate is fixedly installed on the top surface of the receiving hopper.
