Technical Field

[0001] The utility model relates to the field of alumina production equipment, in particular to microwave calcining equipment for alumina production. Background Art

[0002] Alumina is an important ceramic material with a wide range of applications in the industrial field. Alumina exhibits excellent performance in the fields of optics, electricity and thermodynamics. In the process of alumina processing, its synthesis methods include solid phase method and gas phase method. The solid phase method is to grind and calcine aluminum or aluminum salt, and directly obtain nano alumina after solid phase reaction. A calcining furnace is used for calcination. The calcining furnaces currently used are divided into traditional calcining furnaces and microwave calcining furnaces according to different heating methods.

[0003] Traditional heating furnaces heat by transferring energy, resulting in a large amount of energy loss in the environment. Microwave calcining furnaces heat internally by energy conversion, with less energy loss. After microwave calcination, alumina has a high temperature, and manual removal of alumina is dangerous. Therefore, it is particularly necessary to develop a microwave calcining equipment that has autonomous input and output of alumina to reduce danger. Summary of the invention

[0012] Preferably, there are multiple pusher shafts.

[0013] Compared with the prior art, the beneficial effects are:

[0014] 1. The utility model utilizes a horizontal slider to push the lifting frame and the pushing shaft to move horizontally in the box body. The lifting frame controls the pushing shaft to move vertically in the box body. Alumina products are input into the box body from a feeder. The horizontal slider and the lifting frame are used to push the alumina products on the feeder onto a supporting plate. After microwave calcination, the horizontal slider and the lifting frame are used to push the alumina products on the supporting plate onto a discharging machine, which reduces the risk compared to manual removal.
