a vacuum oven

Abstract

The invention discloses a vacuum drying box which comprises a box body, heating devices, a shooting device and a control device, wherein the heating devices are arranged in the box body; the shooting device is arranged at the top of the box body; and the control device is arranged at the bottom of the box body. According to the vacuum drying box disclosed by the invention, since the shooting device is arranged at the top of the box body, and is used for recording running conditions in the box and transmitting the shot information to a computer in time, a worker can conveniently monitor the whole working process at any time and handle problems immediately once finding any problem, thus, the large failure of the equipment is avoided, meanwhile, the running conditions in the drying box can be observed and abnormal conditions in the drying oven can be found in time, therefore, a good monitoring effect on running of the whole drying box is realized, the drying effect of the drying box is guaranteed effectively and further production demands are met better.

Description

technical field [0001] The invention relates to a vacuum oven, in particular to a vacuum oven. Background technique [0002] Vacuum oven is a box-type drying equipment that dries dry materials under negative pressure conditions. It uses a vacuum pump to pump air and dehumidify, so that a vacuum state is formed in the working room, the boiling point of water is lowered, and the drying speed is accelerated. [0003] Most of the existing vacuum ovens include a cylindrical or cubic box with an air inlet and an air inlet. The air outlet is directly connected to the vacuum pump, or connected to the suction tower or drying tower and then connected onto the vacuum pump. Heating elements are installed on the outer periphery of the circular box or on the upper and lower side walls of the square box. The box is divided into several layers by a horizontal grid. The material tray containing the material is placed on the grid, the door is closed, the vacuum pump is used to evacuate, an...

Problems solved by technology

[0004] During its use, some failures often occur. However, once a failure occurs, the maintenance personnel will check all parts of the entire equipment. Not only will a lot of time be wasted during the entire inspection process, but also in the entire production process. During the process, the staff can't observe the working conditions in the oven, and can't know whether the temperature in the oven needs to be guaranteed, and the drying effect cannot be guaranteed, so it can't really meet the needs of production.
