Description

Technical Field

[0001] The utility model relates to the technical field of white corundum preparation, in particular to a calcining furnace for preparing surface-plated white corundum abrasive. Background Art

[0002] White corundum is made from industrial alumina powder using modern, new, and unique process technology. The calcining furnace is a type of equipment used for high-temperature processing, powered by natural gas, oil, and electricity, and is used for ironmaking, rare metal recovery, catalyst production, environmental improvement, and the production of specialty chemicals.

[0003] A search of the patent publication number CN217856523U discloses a calcining furnace for preparing surface-coated white corundum abrasive, comprising a mounting tube, a mounting frame provided at the upper end of the mounting tube, and a drive motor fixedly provided on the mounting frame. The drive motor drives the mounting shaft to rotate, so that the mounting shaft synchronously drives the second bevel gear, the threaded rod, and the stirring member to rotate, so that the second bevel gear drives the rotating shaft and the rotating cam to rotate through the first bevel gear, so that the push rod drives the crushing knife up and down under the action of the push spring. Since the crushing knife and the threaded rod are threadedly connected, the crushing knife rotates while moving up and down under the action of the push rod, thereby crushing the attachments on the surface of the falling white corundum. While the stirring member rotates, the grinding disc is driven by the connecting shaft, so that the grinding disc can rotate, thereby rotating between the grinding disc and the stirring member, grinding the falling white corundum, and separating the attachments from the white corundum.

[0004] When the existing equipment is driven, the threaded rod is exposed inside the calcining furnace and will be repeatedly hit by the white corundum abrasive, causing damage and easily jamming the stirring parts, causing the equipment to stop. Therefore, we proposed a calcining furnace for preparing white corundum abrasive with a surface coating to solve the above problems. Utility Model Content

[0007] Preferably, the driving component includes a driven gear ring connected to the outside of the equipment box through a connecting key, the bottom end of the driven gear ring is meshed with a driving gear, and one end of the driving gear is connected to the motor through a driving shaft.

[0008] Preferably, the two supporting components each include a sleeve ring, the bottom ends of the two sleeve rings are symmetrically welded with supporting legs, and a connecting rod is installed between the two right supporting legs among the four supporting legs through bolts.

[0009] Preferably, the left sleeve ring of the two sleeve rings is sleeved on the feed pipe opening through a rolling bearing, and the right sleeve ring of the two sleeve rings is sleeved on the equipment box through a rolling bearing.
