Description

Technical Field

[0001] The utility model relates to the technical field of feeding mechanisms, in particular to an alumina feeding and slag removing device. Background Art

[0002] The traditional fresh alumina feeding system is a system in which the fresh alumina is fed from the manual feeding platform of the alumina warehouse via a belt conveyor to the fresh alumina bin. During this transportation process, debris from alumina woven bags, broom debris, friction materials from belt conveyors, medium plate materials, fine sand, etc. are mixed into the fresh alumina, resulting in unstable feeding amount from the fresh alumina bin to the dust collector, and even blockage, which seriously affects the normal operation of the feeding system and the dust collection efficiency.

[0003] At present, the cleaning method is simply manual, and the cleaning process causes a lot of short-term system shutdown phenomena. It is difficult to control the balanced feeding amount. The unstable feeding amount increases the difficulty of environmental protection management and emission compliance. After searching, it was found that the application number is CN201521069278.0, and the name is Alumina Desanding, Deslagging and Metering Device. The application uses an upper box for deslagging. However, during the vibration screening process, the dust generated is difficult to absorb and remove, which easily causes pollution to the working environment. Further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0038] Working principle:

[0039] When alumina is being fed, it is fed from the feeding pipe 1 into the metering pipe 2 for metering and loading. Subsequently, the alumina is conveyed to the square swing vibrating screen 4 through the first chute 3. The swing vibrating screen has two stages of screening. The first stage is an 8-mesh screen that separates the debris in the alumina woven bag, broom debris, belt conveyor friction, and medium-plate materials. The separated waste is discharged along the first row of waste outlets 14. The second stage is a 20-mesh screen that separates the alumina fine sand. The fine sand is discharged through the second row of waste outlets 15. The qualified alumina enters the second chute 12 through the discharge port 13 to complete the screening. For feeding and slag removal, the vibration system adds frequency conversion regulation to control its balanced feeding amount. The device removes impurities generated during the alumina feeding process through screening by the square swing vibrating screen 4, thereby improving the cleanliness of the feeding and the production efficiency. At the same time, when screening and slag removal of alumina is carried out, the vacuum pump 11 is started to extract the air inside the cyclone dust collector 8, so that the dust collecting hopper 7 is under negative pressure. The dust generated during the screening process passes through the dust collecting hopper 7 and enters the cyclone dust collector 8 for cyclone dust removal, thereby avoiding the problem of dust escape, improving the cleanliness of production, and facilitating clean production.
