Problems solved by technology

There are dozens or hundreds of heating beam tubes in the vacuum drying chamber. If a certain heating beam tube leaks due to wear and corrosion, the leaking position of the heating beam tube is not easy to check, and it is even more difficult to repair. The entire vacuum drying chamber is scrapped and cannot be used

Abstract

The invention discloses an electric heating vacuum drying bin. The electric heating vacuum drying bin comprises a drying bin, a heat insulating layer, a sealing cover and a conducting ring. The dryingbin comprises a bin body, an exhaust pipe, the sealing cover, electric heating devices, a transmission shaft and a bracket. Power of an external power source is transmitted to the electric heating devices through the conducting ring, the electric heating devices adjust the electric heating power according to the temperature needed in the material drying process, and the accurate temperature control of the electric heating devices can meet the temperature requirement of materials in the material drying processing process. Heat generated by the electric heating devices is directly conducted toheat the materials in the drying bin, the heat conducting speed is increased by 3-10 times, the efficiency of drying the materials in the drying bin is improved, and the purpose of rapidly drying thematerials is achieved. When one electric heating device is damaged and leaks, only the electric heating device does not work, and the use of the whole electric heating vacuum drying bin is not affected. The electric heating vacuum drying bin has a simple structure, and the heating temperature can be accurately controlled.

Description

technical field [0001] The invention relates to a vacuum drying chamber, in particular to an electrically heated vacuum drying chamber. Background technique [0002] Now the vacuum drying chamber of the vacuum dryer is composed of a drying chamber and a heating chamber. Heating and heat exchange is carried out by adding a high-temperature medium into the interlayer between the drying chamber and the heating chamber. The heat is in contact with the wet material through the chamber body of the drying chamber. , The heat dissipation area of ​​the drying bin body is small, and the heating area of ​​the material is small, which affects the heat conduction speed of the heat required for drying the material. [0003] At present, the vacuum drying chamber of some vacuum dryers uses heating beam tubes to increase the heat dissipation area, and the opening end of the heating beam tubes is fixedly welded on the chamber body of the drying chamber. In the same way, the high-temperature ...
