Lower cone body of cerement bin and manufacturing process of lower cone body

Abstract

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

Description

technical field [0001] The invention relates to the field of machinery, in particular to a lower 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 directl...

[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
