A New Type of Vacuum Drying Oven

Abstract

The invention discloses a novel vacuum drying oven. The novel vacuum drying oven comprises an oven body, a drying chamber, a hot air circulation system and a vacuum unit, wherein a vertical partition is arranged in the drying chamber and divides the drying chamber into a storage cavity and an air outlet cavity; heating tubes are distributed at the inner bottom of the storage cavity; heating plates are arranged on two side walls of the storage cavity; the hot air circulation system comprises a magnetic fluid circulating fan mounted on the top wall of the air outlet cavity; the rotating shaft of the fan penetrates the top wall; the air outlet part of the fan is located in the air outlet cavity; an air inlet is formed in the vertical partition and corresponds to the air outlet part; the storage cavity and the air outlet cavity are communicated through the air inlet. Therefore, the interior of the drying chamber is designed into a unique air duct structure, and through cooperation of the magnetic fluid circulating fan, air is uniformly circulated, and the temperature distribution uniformity in the drying chamber is extremely good; a cooling water path for cooling down a magnetic fluid can cool down the magnetic fluid in real time, so that the vacuum leakproofness, the service performance and the safety performance of the drying oven are better.

Description

technical field [0001] The invention relates to the technology in the field of vacuum drying equipment, in particular to a novel vacuum drying oven. Background technique [0002] At present, vacuum drying ovens are widely used in biochemistry, chemical and pharmaceutical, medical and health, agricultural scientific research, environmental protection and other research and application fields, for powder drying, baking, and disinfection and sterilization of various glass containers. It is especially suitable for fast and efficient drying of heat-sensitive, easily decomposed, easily oxidized substances and complex composition items. [0003] Existing vacuum drying ovens generally have air leakage after a long period of use. It is difficult to ensure the high vacuum degree of the drying oven. There are potential safety hazards during use, and frequent replacement of seals costs maintenance, The replacement time is long, which delays the use of the equipment and reduces the util...

Problems solved by technology

[0003] Existing vacuum drying ovens generally have air leakage after a long period of use. It is difficult to ensure the high vacuum degree of the drying oven. There are potential safety hazards during use, and frequent replacement of seals costs maintenance, The replacement time is long, which delays the use of the equipment and reduces the utilization rate of the equipment; in addition, the traditional vacuum drying oven also has problems such as poor temperature uniformity, unstable performance, and poor drying consistency
