A multifunctional nuclear magnetic tube drying oven

Abstract

The invention discloses a multifunctional nuclear magnetic tube drying box, which comprises a box body, a positioning mechanism, a power mechanism, an outer drying mechanism, a recovery box and an inner drying mechanism; the outer drying mechanism includes a top box, a plurality of fixing seats, a plurality of A blower and a first heating mechanism are provided; the inner drying mechanism includes a flow distribution box, a plurality of drying pipes, and a second heating mechanism. The present invention facilitates blowing the nitrogen heated by the second heating mechanism into the inner cavity of the nuclear magnetic tube by setting the inner drying mechanism to dry the inner cavity of the nuclear magnetic tube; by setting the outer drying mechanism, it is convenient for multiple A blower blows the dry air heated by the first heating mechanism to the outer wall of the nuclear magnetic tube, which is beneficial to the drying of the outer wall of the nuclear magnetic tube; by setting the positioning mechanism, it is convenient for the power mechanism to drive the positioning cylinder in the positioning mechanism to move, so that the drying box can be used for NMR tubes of different lengths; by setting a recovery box in the box, it is convenient to recover the nitrogen gas that dries up the inner cavity of the NMR tube, which is beneficial to reduce the consumption of nitrogen.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a multifunctional nuclear magnetic tube drying box. Background technique [0002] If the cleaned NMR tubes are left to dry naturally at room temperature, it will take several days before they can be used, which is too long; the conventional drying method for NMR tubes is to dry them in an oven at high temperature. Although the NMR tubes are made of quartz and can withstand high temperatures, they are When drying, it is not suitable for the temperature to be too high. The NMR tube is easily deformed at high temperature. Long-term drying at high temperature will increase the adverse factors affecting the experiment; the NMR tube that has been dried at high temperature is easy to cause broken tubes; The nuclear magnetic tube drying equipment can only dry one type of nuclear magnetic tube, and its application range is narrow; there are also problems such as low drying effici...

[0002] If the cleaned NMR tubes are left to dry naturally at room temperature, it will take several days before they can be used, which is too long; the conventional drying method for NMR tubes is to dry them in an oven at high temperature. Although the NMR tubes are made of quartz and can withstand high temperatures, they are When drying, it is not suitable for the temperature to be too high. The NMR tube is easily deformed at high temperature. Long-term drying at high temperature will increase the adverse factors affecting the experiment; the NMR tube that has been dried at high temperature is easy to cause broken tubes; The nuclear magnetic tube drying equipment can only dry one type of nuclear magnetic tube, and the scope of application is narrow; there are also problems such as low drying efficiency and poor controllability of drying temperature.
