Description

Technical Field

[0001] The utility model relates to the technical field of medicine production, in particular to a concentration device. Background Art

[0002] Concentrators play a vital role in the pharmaceutical process, especially in the solvent removal step. Through evaporation technology, the concentrator can evaporate the solvent in the drug solution to obtain a concentrated drug solution or solid drug, which can help improve the purity and stability of the drug and ensure that the final product meets pharmaceutical standards and is safe and effective.

[0003] Traditional concentration devices usually use a single-chip microcomputer to control the operation of the motor, which drives the motor to rotate the stirring paddle or blade to mix the drug ingredients and solvent evenly;

[0004] The traditional concentration device has the following problems: since the temperature in the evaporation barrel needs to be increased during the evaporation process, the traditional concentration device does not have a self-cleaning function, which may cause caking and residue on the inner wall of the evaporation barrel, resulting in uneven distribution of drug components during the evaporation process, resulting in unstable or inconsistent components of the final product. For this reason, we propose a concentration device. Utility Model Content

[0011] Furthermore, a feed pipe is fixedly connected to the feed port at the left end of the upper surface of the evaporation barrel, and a discharge pipe is fixedly connected to the discharge port in the middle of the lower surface of the evaporation barrel. A valve is connected in series in the middle of the discharge pipe to facilitate pouring of medicine and discharging of evaporated medicine.

[0012] Furthermore, a liquid collecting hopper is fixedly connected to the bottom end of the cooling barrel, and a drain pipe is fixedly connected to the middle of the lower surface of the liquid collecting hopper, thereby providing efficient collection.

[0013] Furthermore, it also includes a temperature sensor, which is arranged at the left end of the upper surface of the evaporating barrel. The detection probe of the temperature sensor extends to the inside of the evaporating barrel. The temperature sensor is bidirectionally electrically connected to the single-chip microcomputer to facilitate real-time detection of the internal temperature.

[0014] Furthermore, the self-cleaning stirring mechanism includes a rotating shaft, a stirring rod, a scraper, a sliding hole, a sliding column, a sliding groove and a spring. The rotating shaft is rotatably connected to the top wall of the evaporating barrel, and four stirring rods are fixedly connected to the bottom end of the rotating shaft. The four stirring rods are each provided with a sliding groove inside. The upper end of the inner wall of the sliding groove is slidably connected to a scraper, and one side of the scraper close to the center of the rotating shaft is fixedly connected to a uniformly distributed sliding column. The sliding hole is provided in the inner wall of the sliding groove, and the inner wall of the sliding hole is slidably connected to the outer surface of the sliding column at the adjacent end. A uniformly distributed spring is fixedly connected between the inner side surface of the scraper and the inner wall of the adjacent sliding groove. The spring is sleeved on the outer surface of the sliding column and can adaptively fit the shape of the inner wall.

[0015] Furthermore, the self-cleaning stirring mechanism also includes two sliding holes, two springs, two sliding columns and two scrapers.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the concentrating device has the following advantages:

[0019] 1. During the mixing process, a part of the drug components and solvents may remain on the inner wall of the evaporation barrel, resulting in agglomeration or legacy problems. Scrapers 1 and 2 can scrape the inner wall and bottom wall of the evaporation barrel. They scrape off the residue by contacting the inner wall and bottom wall of the evaporation barrel to ensure the smooth progress of the evaporation process. However, during the scraping process, when scrapers 1 and 2 contact the inner wall and bottom wall of the evaporation barrel, an extrusion force is generated. This is because the friction and pressure between the residue and the scraper push the movement of the scraper. Slide posts 1 and 2 are respectively provided on scrapers 1 and 2, which cooperate with slide holes 1 and 2. When the scraper is pushed by the extrusion force, the slide posts move along the slide holes, thereby compressing springs 1 and 2. The function of the compression spring is to provide a reaction force, so that the scraper can automatically rebound after being subjected to external force and maintain close contact with the inner wall of the evaporation barrel, so that it can adaptively fit the shape of the inner wall, and can more effectively scrape off drug residues, which helps to improve the efficiency of drug evaporation and reduce drug waste.

[0020] 2. During evaporation, the temperature inside the evaporation barrel is monitored in real time through the temperature sensor. Once the temperature reaches the preset threshold, the temperature sensor will send a signal to the single-chip microcomputer. After receiving the signal, the single-chip microcomputer will make corresponding judgments and control the operation of the motor. At the same time, the speed of the motor is adjusted according to the temperature. When the temperature is high, the speed of the motor can be accelerated to increase the movement frequency of the scraper, thereby increasing the number of contacts between the scraper and the inner wall of the evaporation barrel. Conversely, when the temperature is low, the speed of the motor can be slowed down to appropriately reduce the movement frequency of the scraper, which helps to accelerate the evaporation and dispersion of the drug components, thereby improving the uniformity of the evaporation process and ensuring the full release of the drug components.
