Description

Technical Field

[0001] This utility model relates to the field of extraction equipment technology, specifically a polymyxin detection and extraction device. Background Technology

[0002] Polymyxins are a group of polypeptide antibiotics produced by *Bacillus polymyxa*. They are effective against most Gram-negative bacteria. They are soluble in acidic conditions but insoluble in water, methanol, and hexane. They are suitable for infections caused by certain Gram-negative bacteria such as *Escherichia coli*, *Klebsiella pneumoniae*, and *Pseudomonas aeruginosa*. Clinical use is phasing out polymyxins. The production process of polymyxins requires an extraction device to extract the polymyxins produced from the mixture of materials.

[0003] Traditional extraction devices typically involve heating the material for extraction. However, polymyxins are highly sensitive to temperature, and the temperature inside the extraction tank cannot be monitored during extraction, resulting in temperatures that are too high or too low. This affects the extraction efficiency of polymyxins, and the material residue left on the inner wall of the extraction tank after extraction can easily affect the extraction quality of polymyxins over time.

[0004] According to CN210456092U, an abamectin extraction device includes an extraction tank. The upper part of the extraction tank has an extraction liquid inlet, a gas inlet, and a material addition port. A stirring rod is installed inside the extraction tank. The lower part of the extraction tank has a high-temperature resistant, corrosion-resistant, and flexible filter layer. The middle part of the filter layer is fixed to the bottom end of the stirring rod, and the top of the stirring rod is fixed to the power output end of a lifting cylinder. The bottom of the extraction tank has an extraction liquid outlet and a steam inlet, and the upper part of the extraction tank also has a steam outlet connected to an external condenser. This invention effectively agitates the filter layer by stirring it, preventing clogging and greatly improving extraction efficiency and reducing equipment damage rate.

[0005] The extraction device described above cannot detect the temperature inside the extraction tank when extracting polymyxin, resulting in temperatures that are too high or too low, which affects the extraction efficiency of polymyxin. In addition, material residues remain on the inner wall of the extraction tank after extraction, which can easily affect the extraction quality of polymyxin over time. Therefore, we need to propose a polymyxin detection and extraction device. Utility Model Content

[0026] The filter structure 4 includes a filter tube 41, which is located at the bottom of the discharge pipe 3.

The inner cavity of the filter tube 41 is provided with a primary filter screen 44 and a micro filter screen 45. After connecting the filter tube 41 to the discharge pipe 3, the bolts 43 are removed and inserted into the threaded holes 42, so that the bolts 43 fit against the outer surface of the discharge pipe 3, thus fixing the filter tube 41 to the discharge pipe 3. During extraction, the original solution passes through the primary filter screen 44 and the micro filter screen 45, and the impurities contained in the original solution are filtered through the primary filter screen 44 and the micro filter screen 45, thereby improving the quality of the extracted polymyxin.

[0027] A sealing ring 13 is bonded to the inner cavity of the top end of the filter tube 41. The inner cavity of the sealing ring 13 is press-fitted to the outer surface of the discharge tube 3. The sealing ring 13 improves the sealing performance after the filter tube 41 is connected to the discharge tube 3, preventing the original liquid from flowing out from the top end of the filter tube 41.

[0028] The rotating assembly 7 includes a rotating platform 71 located inside the extraction tank 1.

The outer side wall of the support column 72 is fixedly connected to one end of the connecting rod 8. The rotating rod 6 drives the rotating platform 71 to rotate, and the rotating platform 71 drives the support column 72 to rotate, so that the support column 72 drives the scraper 9 to rotate inside the extraction tank 1 via the connecting rod 8, so that the scraper 9 scrapes the material remaining on the inner wall of the extraction tank 1.

[0029] Four sets of support columns 72 are provided, and the four sets of support columns 72 are distributed around the center on the upper surface of the rotary table 71. By setting the four sets of support columns 72, the four sets of support columns 72 can synchronously drive the four sets of scrapers 9 to scrape the inner wall of the extraction tank 1, thereby improving the cleaning efficiency of residual materials.

Several sets of stirring rods 14 are provided, and the sets of stirring rods 14 are evenly distributed on the outer wall of the support column 72. By setting the stirring rods 14, the support column 72 can drive the connecting rod 8 to rotate, and at the same time drive the stirring rods 14 to rotate, so as to stir and mix the internal materials and improve the mixing efficiency of the materials.

[0031] The surface of the extraction tank 1 is provided with a groove, and the inner cavity of the groove of the extraction tank 1 is provided with an observation window 15. The observation window 15 allows the staff to observe the scraping process of the scraper 9 on the inner wall of the extraction tank 1.

[0032] In practical use, the electric heating element 11 is activated to heat the material inside the extraction tank 1.

Subsequently, the temperature sensor 12 is electrically connected to the temperature display 10 to display the detected temperature, which is convenient for the staff to observe and adjust the temperature. At the same time, the servo motor 5 is activated to drive the rotating rod 6 to rotate, which in turn drives the rotating table 71 to rotate. The rotating table 71 drives the four sets of support columns 72 at the top to rotate. The four sets of support columns 72 drive the scraper 9 to rotate through the connecting rod 8, scraping the material inside the extraction tank 1. When the support columns 72 rotate, they can drive the stirring rod 14 to rotate and stir the material inside the extraction tank 1. When discharging, the raw liquid flows into the filter tube 41 through the discharge pipe. The raw liquid passes through the primary filter screen 44 and the micro filter screen 45. The primary filter screen 44 and the micro filter screen 45 filter the impurities contained in the raw liquid, thereby realizing the detection of the temperature inside the extraction tank 1, improving the extraction efficiency of polymyxin, avoiding material residue on the inner wall of the extraction tank 1, and improving the extraction quality of polymyxin.
