Vacuum drying box for drying ethyltriphenylphosphonium bromide

Abstract

The invention discloses a vacuum drying box for drying ethyltriphenylphosphonium bromide. The vacuum drying box comprises a box body, a box door and a vacuum pump. A drying chamber is arranged in thebox body, the outer end of the box body is connected with the vacuum pump through a gas conveying pipe, apex corners of the drying chamber are arc corners, a bracket, a temperature detector and a sealing tank are arranged in the drying chamber, the top end of the drying chamber is provided with an illumination sterilization lamp and a hot air outlet, the box door is provided with a sight glass, one end of the box door is hinged the box body, the other end of the box door is connected with the box body through an electronic coded lock, and the sight glass is provided with a pair of gloves wornby two hands for operating objects in the box body. The vacuum drying box has the advantages that after ethyltriphenylphosphonium bromide is dried in the drying box, an operator only needs to wear thegloves to put the objects into the sealing tank, then, the dried objects can be effectively prevented from making contact with air, and therefore long-term stable storage of materials is achieved. Meanwhile, the box door is connected with the box body through the electronic coded lock, and safety is effectively improved.

Description

technical field [0001] The invention relates to the field of drying devices, in particular to a vacuum drying oven for drying ethyltriphenylphosphine bromide. Background technique [0002] Vacuum drying has the advantages of low drying temperature, fast drying speed, and the dried items are not easy to be oxidized. It is suitable for drying materials or items. The most commonly used equipment for vacuum drying is a vacuum drying oven, which has been widely used in research and application fields such as biochemistry, chemical pharmaceuticals, medical and health care, agricultural scientific research, and environmental protection. Vacuum drying oven can be used for powder drying, baking and disinfection and sterilization of various glass containers, especially for fast and efficient drying of heat-sensitive, easily decomposed, easily oxidized substances and complex components. [0003] However, the existing vacuum drying oven can only ensure that the material or article is i...

Problems solved by technology

[0003] However, the existing vacuum drying oven can only ensure that the material or article is in an anhydrous and oxygen-free state during drying. When it is removed from the vacuum drying oven after drying, it will still be exposed to the air with water and oxygen.

For chemical materials that need to be stored for a long time later, such as ethyl triphenylphosphine bromide, etc., when they are taken out of the existing drying box, they will still be in contact with the air, which is very unfavorable for long-term storage in the later period

In addition, the opening and closing between the door and the box body of the existing drying box is relatively random, which is not conducive to unified management, and the safety is poor
