Description

Technical Field

[0001] The utility model relates to the technical field of bauxite processing, in particular to a filtering structure for cleaning bauxite. Background Art

[0002] Bauxite, also known as bauxite or bauxite, is primarily composed of aluminum oxide, a hydrated aluminum oxide containing impurities. It is an earthy mineral, white or off-white, with a brownish-yellow or light red hue due to its iron content. It is opaque and brittle. It is extremely difficult to melt and insoluble in water, though soluble in sulfuric acid and sodium hydroxide solutions. It is primarily used in aluminum smelting and the manufacture of refractory materials. Because bauxite is often contaminated by dirt during mining and transportation, it is typically cleaned before processing to remove any dirt adhering to its surface.

[0003] At present, when bauxite is cleaned, the bauxite raw materials are directly rinsed. Since the bauxite raw materials may stick together into lumps, direct rinsing cannot quickly separate the impurities and dirt adhering to the lumps of bauxite. Moreover, during cleaning, most of the operations require manual labor, which is inefficient. Utility Model Content

[0007] Preferably, a large torque motor is provided at the rear end center position of the first main pulley, and the large torque motor is installed on the top end of the fixed inclined cylinder through a bracket. The large torque motor drives the rotating inclined cylinder to rotate through the first main pulley, the driving belt and the first secondary pulley.

[0012] 1. This filtering structure for cleaning bauxite uses a forklift to load bauxite to the position of the clamping ring, pours the bauxite into the rotating inclined cylinder, and then starts the high-torque motor. The high-torque motor drives the rotating inclined cylinder to rotate through the first main pulley, the drive belt and the first secondary pulley. The coarse materials collide with each other in the rotating inclined cylinder, and the fine materials fall into the fixed inclined cylinder. The bauxite moves to the rear end of the rotating inclined cylinder due to gravity, and the fine materials pass through the holes and fall into the fixed inclined cylinder.
