Crucible stirring device

Abstract

The invention discloses a crucible stirring device which comprises a barrel. The barrel is rotatably installed on a V-shaped support through a rotation shaft, a graphite crucible is installed in the barrel, an electric heater is surrounded on the outer wall of the graphite crucible, an insulation thermal-protective coating is filled between the inner wall of the barrel and the outer wall of the graphite crucible, a gear case is arranged above the graphite crucible, an agitator blade is rotatably installed on the gear case through a bearing, the agitator blade is connected with a rotation transmission device, a material conveying hole is arranged on the middle portion of the agitator blade, an air inflation rapid connector is in crest clearance with the top portion of the agitator blade, the gear case is connected with a vertical movement device, a thermocouple extending in the graphite crucible is installed on the gear case, and the thermocouple is connected with a thermocouple. The crucible stirring device adopts a hollow oil-free graphite stirring shaft and can evenly convey powder or gas to stirring materials through a stirring shaft. A graphite material is adopted so that bearing temperature can be as high as 400-800 DEG C.

Description

technical field [0001] The invention relates to a stirring device, in particular to a crucible stirring device for a laboratory. Background technique [0002] At present, the crucible stirring device used in the laboratory does not have a powder feeding and gas feeding device. It is all based on experience and hand feeling. First, the uneven feeding and high temperature are likely to cause safety hazards. In the existing technology, although the stirring device already has the function of automatic stirring, it still adopts a manual operation mode or needs to install an additional set of devices in the powder feeding and air feeding links. Manual mixing is not uniform enough, and the quality of test samples cannot be guaranteed. Using another set of devices, the space is sometimes not allowed, and the stirring speed of the original stirring material cannot be unified, and the best effect cannot be achieved.
