Embodiment 1

[0029] Embodiment 1. Lysozyme solution crystal growth device in the state of weightless suspension without container in superconducting magnet

[0030] The embodiment of the present invention is a solution to the shortcomings of the prior art, such as inability to handle liquid samples, easy evaporation of solution, difficult volume control, unavoidable pollution, poor observation effect, inability to heat, and difficulty in stably and accurately controlling temperature.

[0031] In the superconducting magnet 19 (as shown in FIG. 2 ), there is a cylindrical cavity with a space of Ф50 mm×1210 mm available for experiments, which is called the magnet experiment cavity 1 . The force of the diamagnetic material in the cavity is related to the position, and the magnetization force on the material in the suspended position (0g position) 14 in the simulated weightlessness state is upward, which is balanced with its gravity.

Embodiment 2

[0045] Embodiment 2. Paraffin wax melting and solidification treatment device in the state of weightless suspension without container in the superconducting magnet

[0046] The device structure of this embodiment is basically the same as that of Embodiment 1, and the differences mainly include: (1) adopt reflected light to observe the processing process of the suspended material, that is, the light source is on the same side of the ultra-small CCD; (2) adopt thermoelectric cooling mode The temperature of the processed material is controlled, and (3) the sample feeding method of lifting the suspension chamber is adopted.

[0047] This embodiment uses reflected light to observe the treatment process of the opaque suspension material 4, which consists of a cold light source and an optical fiber. The cold light source is placed outside the superconducting magnet 19 to provide a cold light source with adjustable brightness. The light source is exported through the optical fiber. En...

Abstract

The present invention discloses a device that can suspend objects in intense magnetic field with large grade and is used for suspending fluid or solid state diamagnetic material and for making the diamagnetic material be sealed in an environment that is sealed and can be heated or cooled and whose temperature is controllable and is observable at any time so as to realize processing of the diamagnetic material in the states of zero gravity no-container and suspension, the present invention comprises a suspension cavity 5, a sample feeding controller 8, a temperature controller 6 and a video pick-up device 2, etc. The suspension cavity is a sealed cavity and can prevent outside environment from polluting the suspension material and prevent the volatilization of fluid sample. Besides, the suspension of the solid diamagnetic sample that is arranged in the suspension cavity can be realized through changing the position of the suspension cavity 5 in the magnet test cavity; the sample feeding controller 8 can realize precisely control the suspension of the fluid diamagnetic sample; the temperature controller 6 can realize heating or cooling of the sample and precision control of the processing temperature of the sample; the video pick-up collector 2 can realize real-time observation and recording of the process of the sample processing.

Description

technical field [0001] The invention relates to a suspension processing device for materials, in particular to a container-less processing device for solid and liquid diamagnetic materials in a weightless state under a strong magnetic environment. Background technique [0002] Material processing technology in space environment is one of the most important research directions in space science research. The material processing in the space environment mainly utilizes the weightlessness condition of the space environment. The condition of weightlessness can eliminate or greatly weaken the phenomenon of convection and sedimentation under the condition of gravity field, which brings new means for material processing and is conducive to obtaining new or materials with special properties. In addition, in the space environment, it is also easy to achieve long-term container-free material handling. The non-container material processing technology mainly utilizes the characteristic...
