Large-flow aluminum oxide automatic sand cleaning and separating equipment and separating method thereof

Abstract

The invention discloses large-flow aluminum oxide automatic sand cleaning and separating equipment. The equipment comprises a material distributing box and three sand removing boxes, the three sand removing boxes are evenly distributed on the periphery of the material distributing box and communicate with the material distributing box, and each sand removing box comprises a motor, a steel wire mesh, a material collecting hopper, a filtering device and a stirring device; the steel wire meshes are arranged in the sand removing boxes, and the stirring devices are arranged in the filtering devices. The invention further discloses a separating method of the large-flow aluminum oxide automatic sand cleaning and separating equipment. Aluminum oxide is filtered through the steel wire meshes and then collected into the filtering devices to be filtered again; the stirring devices stir aluminum oxide containing impurities into discharging pipes, then the aluminum oxide is discharged into full-automatic hardened material removing device to be screened, and clean aluminum oxide is obtained finally. According to the equipment and the method, two-stage filtration and two-stage sand removal can be realized, the aluminum oxide treatment capacity can reach 300 tons per hour, the sand removal efficiency is high, sand removal is thorough, and the sand removal effect is good.

Description

technical field [0001] The invention belongs to the technical field of alumina treatment, and in particular relates to a large-flow alumina automatic sand cleaning and separation device and a separation method thereof. Background technique [0002] The production process of alumina is the process of separating aluminum from soil by physical and chemical methods. Due to the two-sided nature of aluminum, aluminum exists in a large amount in the state of oxide minerals in nature, and at the same time it is accompanied by a variety of oxide minerals. And compound minerals, which makes the separation process of alumina complicated and difficult to grasp. [0003] The invention patent with the application publication number of CN107362975A discloses an automatic alumina desanding and impurity removal device, including a material chamber, a winnowing chamber, a gas collection chamber, an air supply system and a PLC automatic control system; And the outlet, the outlet is provided w...

AI Technical Summary

Problems solved by technology

However, this equipment has a limited amount of alumina sand removal, which cannot meet the large demand of industrial enterprises for alumina. During the sand removal process, there are large pieces of compaction, which is prone to clogging, low sand removal efficiency, large residual impurities, and incomplete sand removal.
