Description

Technical Field

[0002] The inside of the charge oven is always kept at high temperature for drying, and to improve the utilization rate of heat, it is often sealed. However, if the sealed charge oven is kept at high temperature for a long time, the internal air pressure will be too high, which will cause an explosion and cause a safety accident. Therefore, the exhaust device is very important. However, the exhaust device of most charge ovens is a simple outlet and cannot adjust the gas output by itself. For some old masters, they will adjust the exhaust volume by themselves according to the different materials in the oven and the different environments. Obviously, it is not possible to achieve this with the existing exhaust device.

The utility model uses a fixed plate, a first motor, a screw and a first bearing, so that the first motor can drive the fixed plate to move through the screw, and then the fixed plate can adaptively fix the oven, and the two ends of the oven can be sleeved inside the first bearing to cooperate with the rotating mechanism to keep rotating, thereby improving the practicality of the device. The shortcoming of this utility model is that the exhaust volume cannot be adjusted manually. Utility Model Content
