Upper cone body of cerement bin and manufacturing process of upper cone body

Abstract

The invention provides an upper cone body of a cerement bin and a manufacturing process of the upper cone body. The upper cone body comprises a plurality of upper cone body splicing modules which are the same in size. The upper cone body splicing modules are assembled into the upper cone body. Each upper cone body splicing module comprises an upper cone body splicing module body, wherein upper cone body strip-shaped flanges are arranged on the left side and the right side of the upper cone body splicing module body respectively, and the upper cone body strip-shaped flanges are integrally formed through a hydraulic machine. The upper cone body strip-shaped flanges of every two adjacent upper cone body splicing modules are installed together through fastening pieces. An upper cone body arc-shaped flange is welded to the lower end of each upper cone body splicing module body. Each upper cone body arc-shaped flange is fixedly connected with the upper end of a middle cylinder. By means of the upper cone body and the manufacturing process, the production cycle is greatly shortened, cost is greatly reduced, all bin bodies are the same in size, the upper cone bodies can be produced in batches, standardization is achieved, transportation is convenient, and the upper cone body can be rapidly assembled on site.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an upper cone of a cement silo and a manufacturing process thereof. Background technique [0002] At present, the cement silos commonly used in the market generally have a capacity of several hundred tons, are relatively large, and need to be welded in sections. They are roughly divided into an upper cone, a middle cylinder, and a lower cone, all of which are assembled by pieces. In the prior art, the flanges are generally welded directly around the silo pieces. This connection method requires a large number of welding workers and solder. Pollution and waste of solder resources. In addition, due to manual welding, there will inevitably be deviations between the silo pieces. After the overall assembly, the gaps are too large and water seepage is easy, there are many welds, and the entire silo is skewed. The production cycle of the silo in this way is long and the cost is high. If direct...

[0002] At present, the cement silos commonly used in the market generally have a capacity of several hundred tons, are relatively large, and need to be welded in sections. They are roughly divided into an upper cone, a middle cylinder, and a lower cone, all of which are assembled by pieces. In the prior art, the flanges are generally welded directly around the silo pieces. This connection method requires a large number of welding workers and solder. Pollution and waste of solder resources. In addition, due to manual welding, there will inevitably be deviations between the silo pieces. After the overall assembly, the gaps are too large and water seepage is easy, there are many welds, and the entire silo is skewed. The silo production cycle of the method is long and the cost is high

If the silo pieces of the upper cone, the middle cylinder and the lower cone are directly welded, the above-mentioned shortcomings will be more prominent
