Description

Technical Field

[0001] This utility model relates to the field of antibiotic extraction technology, specifically to a device for separating, enriching, and extracting antibiotics in water. Background Technology

[0002] Since their discovery in the 20th century, antibiotics have been widely used in animal disease prevention and control, animal husbandry and aquaculture, and human medicine. Because antibiotics degrade slowly, they remain in the environment for a long time. Through the food chain, they accumulate in plants, animals, and humans, reaching high concentrations. This long-term accumulation in plants, animals, and humans poses a great threat to human health. Therefore, it is necessary to extract and test antibiotics in water bodies.

[0003] In existing technologies, extraction technology utilizes the principle of solubility difference between two immiscible solvents to transfer the solute from one solvent to another, thereby achieving purification. For example, CN216785770U is an extraction device for separating and enriching antibiotics in aquaculture water. It includes a workbench and an extraction chamber. The extraction chamber is fixedly connected to the top outer wall of the workbench, and support legs are fixedly connected to the four corners of the bottom outer wall of the workbench. A rotating motor is fixedly connected to the bottom outer wall of the workbench via a first motor frame. The output end of the rotating motor is fixedly connected to the bottom outer wall of the rotating shaft via a coupling. The temperature inside the extraction chamber is kept stable through a set air valve pipe, a heating motor, and a cooling motor, which is conducive to extraction. However, different water bodies have different pH values, and impurities in the water may affect the extraction efficiency. Furthermore, the extracted antibiotics and solvents need to be separated. This technology cannot solve all the technical problems. Summary of the Invention

[0025] The filter device 3 includes, from top to bottom, a pebble layer 301, a ceramic granule layer 302, and a quartz sand layer 303.

[0026] The extraction device 5 includes: an extraction main tank 501, a nitrogen inlet 502 on the top left side of the extraction main tank 501, a second rotary motor 503 in the middle of the top, an output end of the second rotary motor 503 connected to a second stirring rod 504, the other end of the second stirring rod 504 passing through the extraction main tank 501 and fixed to the bottom of the extraction main tank 501 by a second bearing seat 505, an extraction liquid tank 506 on the top right side of the extraction main tank 501, a temperature regulating device 507 in the middle of the right side of the extraction main tank 501, and a drain outlet 508 at the bottom.

[0027] The temperature regulating device 507 includes a temperature sensor 509, a heater 510, and a cooler 511.

[0028] The evaporation device 7 includes, from top to bottom, a gas-liquid separation chamber 701, an evaporation chamber 702, and a liquid settling chamber 703. The top of the gas-liquid separation chamber 701 has a gas outlet 704 connected to a condensation device 9 via a fourth pipe 8. The evaporation chamber 702 has a heat exchange tube 705 and a liquid settling tube 706 inside, and a heat medium inlet 707 and a heat medium outlet 708 on the outside. The heat exchange tube 705 and the liquid settling tube 706 pass through the evaporation chamber 702, with one end extending into the gas-liquid separation chamber 701 and the other end connected to the liquid settling chamber 703. The left side of the liquid settling chamber 703 has an antibiotic outlet 709.

[0029] The condensation device 9 includes a condensation chamber 901 and a liquid collection chamber 902. The condensation chamber 901 is provided with a condensation pipe 903 inside and a coolant inlet 904 and a coolant outlet 905 on the outside. One end of the condensation pipe 903 is connected to the fourth pipe 8, and the other end extends into the liquid collection chamber 902. The bottom of the liquid collection chamber 902 is provided with a solvent outlet 906.

[0030] When using this invention, the water from which antibiotics are to be extracted is added to the pH adjusting device 1 through the water inlet 104. The pH value of the water is detected by the pH detection probe 108 to see if it is within the set range. If it is not within the preset range, the pH value of the water is adjusted by the acid tank 102 and the alkali tank 103. Preferably, a first stirring rod 106 is provided in the pH adjusting device 1 to stir the water, so that the water is better mixed with the acid and alkali solutions. The first stirring rod 106 is powered by a first rotary motor 105 and is fixed in the pH adjusting tank 101 by a first bearing seat 107. After adjustment by the pH adjusting device 1, the pH value is adjusted to a higher value. Water with a set H value enters the filtration device 3 through the first pipe 2. After passing through three layers of filtration—pebble layer 301, ceramsite layer 302, and quartz sand layer 303—the water enters the extraction device 5 through the second pipe 4. Impurities are filtered out by the filtration device 3 to prevent them from affecting the extraction efficiency. After entering the main extraction tank 501, the extraction liquid is added to the main extraction tank 501 by the extraction liquid tank 506, and the second rotary motor 503 is turned on. The second stirring rod 504 stirs the water, mixing it with the extraction liquid. Antibiotics are transferred from the water into the extraction liquid. After extraction, the mixture is allowed to stand for a period of time. The extract phase is separated from the water. Preferably, during the extraction process, the temperature inside the extraction tank 501 is adjusted by the temperature regulating device 507. After separation, since the extract phase is a light phase, it remains above the water. Then, nitrogen is added into the extraction tank 501 through the nitrogen inlet 502 to blow the extract phase into the third pipe 6. The extract phase enters the evaporation device 7 through the third pipe 6. The evaporation device 7 achieves continuous heating through the hot medium circulation via the hot medium inlet 707 and the hot medium outlet 708. The extract phase passes through the liquid settling pipe 706 and undergoes a heat exchange reaction with the hot medium. Because the solvent of the extract phase has a low boiling point and the antibiotic has a high boiling point, some of the solvent vapors... The solvent is discharged from the gas outlet 704 and enters the condenser 9 through the fourth pipe 8. Some of the unvaporized liquid enters the liquid settling chamber 703 through the liquid settling pipe 706. Due to the vaporization of the solvent in the evaporator 7, the pressure inside the tank changes, resulting in a siphon effect. The unvaporized liquid passes through the heat exchange pipe 705 and circulates for heat exchange until the solvent and antibiotic are separated. The antibiotic settles into the liquid settling chamber and is discharged through the antibiotic outlet 709. The gaseous solvent enters the condenser 903, reacts with the coolant, liquefies, and enters the liquid collection chamber 902 through the condenser 903. After the solvent is cooled, it is discharged through the solvent outlet 906.

Based on the embodiments of the present invention, it will be understood by those skilled in the art that all other embodiments obtained by making various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention and without creative effort are within the scope of protection of the present invention.
