Steel storage bin top feeding auxiliary structure

Abstract

The invention relates to a feeding auxiliary structure, in particular to a steel storage bin top feeding auxiliary structure, which belongs to the building field of industrial steel structures. The steel storage bin top feeding auxiliary structure comprises bin top supporting truss upper chords, bin top supporting truss lower chords and a bin top plate, and is characterized in that a reducing outer layer steel pipe is welded between the bin top supporting truss upper chords and bin top supporting truss lower chords, and a reducing inner layer steel pipe which can be freely replaced is sheathed in the reducing outer layer steel pipe. The steel storage bin top feeding auxiliary structure has the advantages and the effects that since the reducing steel pipe is used at a large-diameter steel storage bin top as a bin top feeding auxiliary device, not only can stored materials be ensured to smoothly flow into a storage bin, but also the problem that the service life is decreased because a bin top supporting body is washed by the stored materials can be solved; and since a casing is added in the steel pipe, the replacement is facilitated, the structure is simple and convenient to construct and the delivery of process special stored materials is not influenced at all.

Description

technical field [0001] The invention relates to a material-cutting auxiliary structure, in particular to a material-cutting auxiliary structure applied to the roof of a large-diameter steel storage silo, which belongs to the field of industrial steel structure construction. Background technique [0002] In the electrolytic aluminum production process, the alumina powder used for electrolytic aluminum is generally transported to the alumina silo through the alumina delivery pipeline. Powdered alumina in pipes needs to be under sufficient pressure to be easily transported. Therefore, when the alumina powder enters the silo, the powder often has a certain pressure. Process professionals generally send the alumina pipeline to the top of the silo, and drive the material into the silo through the hole reserved on the roof of the silo. When the storage material with pressure passes through the roof support structure, it will often cause the storage material to scour the roof supp...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides an auxiliary structure for top feeding of steel storage silos, the purpose of which is to apply variable-diameter steel pipes to large-diameter steel storage silos The roof of the warehouse is used as an auxiliary device for unloading materials on the roof of the warehouse, which can not only ensure the smooth flow of the stored materials into the warehouse, but also solve the problem that the service life of the roof support structure is reduced due to the erosion of the stored materials, and an inner tube is added to the outer steel pipe. Layer tubes for easy replacement
