Description

Technical Field

[0001] The present invention relates to the technical field of extraction, and particularly to a small and efficient extraction device. Background Art

[0002] An extraction device is a type of mass transfer equipment used for extraction operations, capable of achieving perfect separation of the components contained in the feed liquid. It utilizes the principle of liquid-liquid extraction to extract one or several compound components in the mixture solution with another solvent, so as to achieve separation, enrichment, and purification.

[0003] Bisphenol A, also known as BPA, is used in industry to synthesize materials such as polycarbonate (PC) and epoxy resin. BPA is everywhere, from mineral water bottles, medical devices to the inner lining of instant food packaging. Trace amounts of BPA can have an adverse impact on the physiological conditions, reproductive systems, and fetal development of animals. Obesity caused by cancer and metabolic disorders is also considered to be related to it; a newer method is to use magnetic beads to extract bisphenol A from biological samples. Magnetic beads have the advantages of high reaction efficiency, high stability, and greater flexibility. The principle is that various chemical groups can be modified on the surface of magnetic beads. Utilizing the principle that bisphenol A can reversibly bind to carboxyl-labeled magnetic beads, the biological molecules in the sample can be selected and separated. At the same time, due to its superparamagnetism, it can be manipulated by an external magnetic field. Therefore, the operation is more convenient, and this technology is also called solid-phase reversible immobilization method.

[0004] However, the method of magnetic bead operation has not yet achieved miniaturization and portability, requires relatively large equipment, and also consumes more reagents. Traditional methods consume more reagents, rely heavily on equipment, and have relatively high detection costs; due to the existence of some dangerous pathogenic bacteria and viruses, disposable detection has become necessary, but the costs of conventional methods are all relatively high, and the equipment cannot be used disposable, increasing the chances of contamination and infection.

[0005] Therefore, how to provide a small and efficient bisphenol A extraction device is an urgent problem to be solved by those skilled in the art. Summary of the Invention

A hatch 14 is detachably connected to one side of the sample chamber for convenient loading and unloading of samples. The sample chamber 13 is detachably connected to the circulation pipe 11 for convenient replacement of drugs.

[0032] In some other embodiments, the outer peripheral side of the base 1 is fixedly connected with a cover box 16. A filter bucket installation opening is provided at the top of the cover box 16, and the outer side wall of the filter bucket 8 is fixedly connected to the filter bucket installation opening, which is convenient for carrying.

[0033] In some other specific embodiments, an outer discharge pipe 17 is connected to the circulation pipe 11, and a valve 18 is connected to the outer discharge pipe 17. After the extraction is completed, the solution can be discharged through the outer discharge pipe.

[0034] In some other embodiments, both the extraction bucket 3 and the circulation pipe are formed of polyethylene.

[0035] In some other specific embodiments, quick connectors 15 are respectively connected between both ends of the sample chamber 13 and the circulation pipe 11, which is convenient for the quick installation of the sample chamber.

[0036] Specifically, the filter bucket 8 is located above the magnetic rotor 5.

[0037] In some other specific embodiments, the control buttons 2 include a power switch 201, a temperature adjustment knob 202, an ultrasonic adjustment button 203, a rotor adjustment knob 204 and a circulation pump switch 205.

[0038] Specific implementation process:

[0039] Put the solution into the extraction barrel 3, then put the plastic sample into the filtration barrel 8, and then cover the sealing cover 9 on the filtration barrel 8 with the clamp 10 to form a sealed space. Turn on the power switch 201, and start heating the heater 6 by adjusting the temperature control knob 202 to regulate the appropriate temperature.

The sample chamber is equipped with a very fine filter screen to hold the sample so that it is not washed away by the solution, and any material above the nano level can be placed. For example, when extracting bisphenol A, magnetic beads can be placed in the sample chamber. By using the characteristics that various chemical groups can be modified on the surface of the magnetic beads, bisphenol A is adsorbed on the surface of the magnetic beads, and finally the magnetic beads are taken out. The filtration barrel can directly leave the substance residue in the filtration barrel, which is convenient for cleaning. The extraction barrel and its pipelines are all made of polyethylene plastic, making it corrosion-resistant and highly durable, and can be used for a long time. It adopts a closed mode to prevent the random volatilization of harmful substances, ensuring the use safety and environmental safety while achieving high-efficiency extraction.

[0042] This device is used to extract the components in plastics in order to test the qualification of plastic components. In addition, this new type is an environment-friendly device, and the materials in it can be reused, with excellent sealing performance, which can save resources and protect the environment very well.
