Nano-material freeze-drying preparation equipment

Abstract

The invention discloses nano-material freeze-drying preparation equipment. The nano-material freeze-drying preparation equipment comprises a freeze-drying equipment body; a supporting plate is arranged in the freeze-drying equipment body; a freezing box, a pipeline and a vacuum waste gas collecting box are arranged at the top of the supporting plate; the vacuum waste gas collecting box is connected with the freezing box through the pipeline; a refrigerating rotating device, a thermometer and a railway are arranged in the freezing box; the refrigerating rotating device comprises a refrigeratingrod, a supporting base, a motor, a liquid storage barrel, an atomizing spraying head, rollers and a liquid storage barrel top cover; the rollers are mounted at the bottom of the supporting base; therefrigerating rod is mounted on the side of the supporting base; the motor is mounted at the central position of the supporting base; the liquid storage barrel is mounted on an output shaft of the motor; the atomizing spraying head is mounted on the outer surface of the liquid storage barrel; a vacuum air sucking pump is arranged at the top of the vacuum waste gas collecting box; and the nano-material freeze-drying preparation equipment is novel in design, simple in structure, easy to implement and good in using effect.

Description

technical field [0001] The invention relates to the technical field of nanometer preparation equipment, in particular to nanometer freeze-drying preparation equipment. Background technique [0002] Nanomaterials refer to materials that have at least one dimension in nanometer size in three-dimensional space or are composed of them as basic units. With the continuous development of science and technology, nanomaterials have also entered our lives. Nanomaterials are widely used due to their excellent performance. It is loved by everyone, so the society's demand for nanomaterials is also increasing. During the preparation of nanomaterials, it is often necessary to freeze-dry the raw materials of nanomaterials. Therefore, each nanoscale preparation and processing plant needs to be equipped with corresponding freeze-drying equipment. However, on the one hand, when the sublimation solution is frozen, due to the large amount of the solution, the cold distribution is uneven, which a...
