Abstract

The invention relates to a vacuum-environment operation box for preparing nanometer fluid. The upper part of a circular-slot-shape box body is provided with an open slot; a sealing washer is bonded in the open slot on the upper part of the box body; a toughened glass cover plate is placed on the open slot on the upper part of the box body and compresses the sealing washer; the middle part of the box body is provided with a vacuum gauge interface, a pumping hole and an air inlet, and is connected with a vacuum pressure gauge and a vacuum valve respectively; the box body is provided with two operation ports; joints of the operation ports and the box body are provided with protrusions for placing a rubber glove; the outer end of each protrusion is welded with a flange; the rubber glove clings to the flange; the sealing washer covers the rubber glove and the flange; a steel ring clings to the sealing washer; the steel ring is compressed onto the flange through a bolt; the outer side of the steel ring is pasted onto the sealing washer; and operation port sealing cover plates are compressed and sealed on the operation ports through four hold-down bolts. The operation box has the advantages of simple structure, large effective operation space, good sealing effect, comfortable operation observation and capability of playing a great role in ensuring the good properties of the prepared nanometer fluid.

Description

technical field [0001] The invention relates to a vacuum environment operation box, in particular to a vacuum environment operation box used for nano fluid preparation. Background technique [0002] At present, with the development of nanotechnology, the application range of nanomaterials is becoming wider and wider. Especially after the concept of nanofluid was proposed, its research in the field of heat transfer and mass transfer has gradually risen. However, the premise of the study of nanofluid enhanced heat and mass transfer is to prepare uniformly dispersed and stable nanofluid. Among the preparation methods of nanofluids, the dispersion method is the easiest and most commonly used method. The basic process of its preparation is to place the nanopowders in a base liquid such as water or ethylene glycol, and then stir them by magnetic force. Or ultrasonic vibration and other external forces to make it evenly dispersed in the base liquid. Due to the extremely small siz...
