Description

Technical Field

[0001] The utility model relates to the technical field of carbon quantum dot preparation, in particular to a high-efficiency preparation device for carbon quantum dots. Background Art

[0002] Carbon quantum dots are a new type of carbon nanomaterial, which has similar luminescence performance and small size characteristics as traditional quantum dots. It also has the advantages of good water solubility, low biological toxicity and good conductivity, making it widely used in biological imaging and cell labeling, sensors, new energy batteries, ion detection, determination of enzymes in organisms, small molecule analysis and other fields. Selenium-enriched materials promote the growth of microalgae. The introduction of trace element selenium will further enhance the nutritional and medicinal value of microalgae, achieving a superposition effect of one plus one greater than two. It can also be used as raw materials to derive a series of high value-added selenium-enriched products, which have broad market prospects in functional foods, health products, medicines and animal feeds.

[0003] A Chinese patent publication (publication number: CN221062678U) discloses a device for preparing selenium-rich microalgae carbon quantum dot materials, which includes a box body. Through the coordinated use of the box body, reactor, through slot, mounting shell, fan and heating rod, the interior of the box body can be heated and cooled, so that the high temperature environment and the reactor are integrated, which is convenient for industrial production. At the same time, the alternating use of cold and hot air can quickly cool down and heat up, thereby shortening the reaction time, which is beneficial to improving the efficiency of carbon quantum dot preparation. By setting a dustproof net, it plays a role in filtering dust and other impurities in the outside air, and by setting a slot, it plays a role in filtering dust and other impurities in the outside air. In order to facilitate the disassembly and assembly of the dust-proof net, the dust-proof net can be disassembled and replaced. By setting a first filter screen, larger particles of impurities in the carbon quantum dot material can be removed. By setting a first installation groove, the first filter screen can be disassembled and replaced. By setting a second filter screen, smaller particles of algae residue in the carbon quantum dot material can be filtered. However, in actual use, the material in the reactor is stationary, the collision between the reactants is reduced, and a rapid reaction cannot be performed, which reduces the preparation efficiency of the carbon quantum dots and is not convenient for the preparation and use of the carbon quantum dots. For this reason, an efficient preparation device for carbon quantum dots is proposed. Utility Model Content
