Aluminum oxide warehousing system and conveying and storing method thereof

Abstract

The invention relates to an aluminum oxide warehousing system and a conveying and storing method of the aluminum oxide warehousing system, and belongs to the technical field of aluminum oxide warehousing. The aluminum oxide warehousing system comprises a material warehousing part and a material conveying part. A radial structure is adopted for a warehouse top feeding pipe of the material warehousing part, the warehouse bottom is in a funnel shape, a vertical feeding pipe in a warehouse is added in the warehouse, so that aluminum oxide in the warehouse diffuses to the periphery after falling off, the dissociation phenomenon caused by uneven feeding is effectively reduced, the phenomenon of uneven stress on a warehouse body caused by uneven stack of the aluminum oxide is eliminated, and stability of the warehouse body is improved; an air supply channel is added in the warehouse bottom and can provide disturbing force for the static aluminum oxide at the bottom in the air supplying process, so that the aluminum oxide flows out of the warehouse rapidly and the problem of dead mass areas is solved. According to the material conveying part, the material conveying distance is shortened, and conveying flexibility is increased; the diameter of the warehouse body is larger, the warehousing capacity reaches 3-5 million tons, overall occupied area of the warehouse system is small, warehouse manufacturing cost is reduced substantially, and therefore the requirement of the aluminum oxide production capacity can be met completely.

Description

technical field [0001] The invention belongs to the technical field of alumina storage, and in particular relates to an alumina storage system and a transportation and storage method thereof. Background technique [0002] With the advancement of alumina production technology, the single-line production capacity of alumina is getting higher and higher, and the requirements for alumina storage bins are also getting higher and higher. [0003] At this stage, traditional alumina storage silos are roughly divided into two categories, one is ordinary flat-bottomed silos, which are floor-to-ceiling silos, and the other is small-diameter silos. For ordinary flat-bottomed warehouses, due to the flat-bottomed structure of the warehouse bottom, a large area of ​​dead materials will be formed at the bottom of the warehouse after unloading. Aluminum will increase the pressure of the silo, which will directly affect the service life of the silo and cause potential safety hazards. Since t...

AI Technical Summary

Problems solved by technology

For ordinary flat-bottomed warehouses, due to the flat-bottomed structure of the warehouse bottom, a large area of ​​dead materials will be formed at the bottom of the warehouse after unloading. Aluminum will increase the pressure of the silo, which will directly affect the service life of the silo and cause potential safety hazards. Since the accumulated alumina cannot be unloaded, it will directly cause waste of alumina and increase production costs; for small-diameter silos , in order to solve the problem of the dead material area of ​​the ordinary flat bottom warehouse, the bottom of the warehouse is set as a large cone angle structure, but the overall height of the warehouse body is inevitably raised, which in turn causes the stability of the warehouse body to deteriorate

[0004] Traditional alumina storage silos still face a common problem. They cannot be built with a large diameter, and the storage capacity is mostly 10,000 to 20,000 tons. For a single silo, it can meet the increasing alumina production capacity requirements, and often An alumina project needs to build multiple alumina storage bins to meet the production capacity requirements, which increases the floor area and storage cost, and the transportation distance of alumina is too long and the flexibility is poor, which virtually restricts the development of alumina projects
