CN201951900U - Shuck structure of large heat-preservation storage container - Google Patents

Abstract

The utility model provides a shuck structure of a large heat-preservation storage container, which comprises at least two cylindrical sheet metal, and is characterized in that the top end of the first cylindrical sheet metal forms a minor diameter port after going through a spinning process; the minor diameter port is inserted into the bottom of the second cylindrical sheet metal adjacent to the first cylindrical sheet metal. According to the utility model, the sheet metal needing to be welded is spun, so the diameter of the upper end of the sheet metal is reduced and the insertion and the connection of the next sheet metal with the previous sheet metal are facilitated; an interface of the spun sheet metal is smooth, the rigidity is simultaneously increased, and the insertion position is not welded and is flexible, so expansion caused by heat and contraction caused by cold are avoided.

Description

A kind of large insulation reservoir vessel skin construction

Technical field

The utility model relates to a kind of double-deck large insulation reservoir vessel skin construction that has.

Background technology

Making to large insulation reservoir vessel crust at present is generally continuous welding process or pipe reducer grafting technology.The large insulation reservoir vessel because diameter is big, highly high, be placed on usually outdoor, four seasons temperature inequality, tank body can expand with heat and contract with cold, crust can be out of shape usually.So common crust adopts continuous welding process and pipe reducer grafting technology, and the slab full weld has not only increased cost, but also is can produce to expand with heat and contract with cold, and causes the equipment distortion.Though pipe reducer grafting technology has solved the phenomenon of expanding with heat and contract with cold, can increased making intensity, in making engineering, very easily scratch crust, the interface unfairness influences outward appearance.

Summary of the invention

The purpose of this utility model provide a kind of manufacture difficulty low and can generation equipment the skin construction of distortion.

In order to achieve the above object, the technical solution of the utility model has provided a kind of large insulation reservoir vessel skin construction, comprise at least two cylindrical plates, it is characterized in that, the top of the first cylindrical plate forms small diameter ports through behind the spinning process, and this small diameter ports is inserted the bottom of the second cylindrical plate adjacent with the first cylindrical plate.

The plate that the utility model will weld carries out spinning, and its upper end diameter is dwindled, and in order to next piece plate and its grafting, the interface of the plate of process spinning is smooth, and rigidity has also obtained increase simultaneously, and splicing position does not weld, and is scalable, avoids expanding with heat and contract with cold.

Fig. 2 is the partial schematic diagram of Fig. 1 part i.

The specific embodiment

Specify the utility model below in conjunction with embodiment.

As shown in Figures 1 and 2, a kind of large insulation reservoir vessel skin construction that provides for the utility model, comprise at least two cylindrical plates, the top of the first cylindrical plate 1 is through forming small diameter ports 2 behind the spinning process, this small diameter ports 2 is inserted the bottom of the second cylindrical plate 3 adjacent with the first cylindrical plate 1.

Claims (1)

1. large insulation reservoir vessel skin construction, comprise at least two cylindrical plates, it is characterized in that, the top of the first cylindrical plate (1) forms small diameter ports (2) through behind the spinning process, and this small diameter ports (2) is inserted the bottom of the second cylindrical plate (3) adjacent with the first cylindrical plate (1).
