Controllable blast or vacuum drying oven

Abstract

The invention discloses a controllable blast or vacuum drying oven comprising a box body, an air inlet pipe, a blast pipe, an air blower, a vacuum tube, and a vacuum pump; the inner layer of the box body is provided with a heating device and a heat preservation wall; the heat preservation wall is distributed on the periphery of the heating device and an internal wall face of the box body; the airinlet pipe and the blast pipe are separately connected with an air inlet and an air outlet; the air inlet pipe is connected with a inert gases pot; the air inlet pipe and the blast pipe are provided with flow control valves; a solenoid valve is arranged on the vacuum tube; the blast pipe is connected with the air blower; the vacuum tube is connected with the vacuum pump; a loading support is arranged on the internal wall face, and the internal wall face is also provided with a temperature control module and a safety monitoring module; and the heating device, the safety monitoring module, the temperature control module and the air blower are both electrically connected with an external controller. Heat condition is fully used to handle the metal with low temperature in an internal stress heat treatment, the drying condition can be switched, vacuum or the dryness of the blast can be switched, and multiple working conditions are applied.

Description

technical field [0001] The invention relates to the field of ovens, in particular to a controllable blast or vacuum drying oven. Background technique [0002] Ovens are frequently used equipment in industry, including blast ovens, vacuum ovens, etc. Most of the existing ovens are equipped with a suction port and an air inlet casing, and heating elements are installed in the casing or on the side walls. 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, and then the heating element is started to heat the inside of the oven through heat radiation, and at the same time, the items in the oven Heating to achieve the purpose of drying. [0003] After forming, the robot joints need grinding, surface coating, drying and other steps. During drying, there is a certain temperature. Although the temperature is relatively low compared with the special anne...

Problems solved by technology

[0003] After forming, the robot joints need grinding, surface coating, drying and other steps. During drying, there is a certain temperature. Although the temperature is relatively low compared with the special annealing process, its impact is not negligible. , since the oven has been running, it will have a certain impact on the metal material, and this impact is difficult to estimate
