Description

A kind of calandria for vapour iron

Art

This utility model relates to a kind of calandria for vapour iron

Background technology

For vapour iron calandria due to work time need to bear pressure, Structural strength calls is higher, there are three kinds of modes in the market, the first is the mode using aluminum die casting, by good for upper and lower pot die casting, then being assembled by upper and lower boiler with screw, this mode has, along with the aging of sealing ring, the risk leaked, and seldom uses；The second way is that upper and lower pot uses rustless steel pot to weld together, heating part uses aluminium diecasting, is assembled into bottom lower pot body by aluminium diecasting by screw, and this mode the most still uses a large amount of, subject matter is relatively costly, and heating part is the highest with lower pot body pyroconductivity；The third mode is the lower pot body soldering aluminium sheet and aluminum electrothermal tube occurred in recent years, and this mode has been increasingly becoming the market mainstream.But in practice, the second the most easily tears with the third rustless steel pot weld and blows, the third mode also has the risk of aluminium sheet cracking when pressure-bearing.

Utility model content

In place of this utility model is according to above-mentioned the deficiencies in the prior art, based on the third mode, a kind of new calandria for vapour iron is proposed so that welding aluminum sheets is difficult to disengagement, upper and lower pot Welding Structure can bear higher pressure；

The technical solution adopted in the utility model is:

A kind of calandria for vapour iron, mainly includes upper pan body, lower pot body, aluminium sheet, aluminum electrothermal tube and joint.

In the above-mentioned calandria for vapour iron, upper pan body inserts lower pot body in an interference fit, then uses argon arc welding upper and lower pot to be welded together in lower pot body edge.

In the above-mentioned calandria for vapour iron, the thickness of one lower pot body pot wall of outwardly convex at lower pot body edge 5mm, and be still that straight flange is without flange, upper pan body edge chamfering 1 × 45 °, the external diameter bigger than the internal diameter of lower pot body high spot 0 of upper pan body to 0.2mm.

In the above-mentioned calandria for vapour iron, on lower pot body, soldering has aluminium sheet and aluminum electrothermal tube.

In the above-mentioned calandria for vapour iron, aluminium sheet diameter 5-10mm less than lower pot body diameter.

In the above-mentioned calandria for vapour iron, upper pan body is welded with the joint for steam of intaking, go out.

Beneficial effect: upper and lower pot is isodiametric disc, material thickness is 1-1.5mm, aluminium sheet 5-10mm less than lower pot body diameter, upper and lower pot R angle is 2-5mm, so aluminium sheet edge just at the starting the arc of R angle attached closely, rigidity herein is relatively strong, and during bottom of pot body bearing strain, aluminium sheet is the most easy to crack.

The thickness of the outwardly lower pot body pot wall of lower pot body edge 5mm, and be still that straight flange is without flange, upper pan body is straight flange chamfering, upper pan body is pressed into lower pot body in an interference fit, then weld in lower pot body edge, such structure makes weld only to bear pulling force, and bearing strength can reach several times of original structure.

Detailed description of the invention

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.It should be noted that in the case of not conflicting, the embodiment in the application and the feature in embodiment can mutual combination in any

As Figure 1-Figure 5, a kind of calandria for vapour iron, mainly include upper pan body 1, lower pot body 2, aluminium sheet 3, aluminum electrothermal tube 4 and joint 5.The joint 5 for steam of intaking, go out it is welded with on upper pan body.Upper and lower pot 1,2 uses the mode of hardware stamping to shape, smooth bottom lower pot body, for soldering aluminium sheet 3 and aluminum heat-generating pipe 4, the effect of aluminium sheet be the even heat by aluminum heat-generating pipe be delivered in pot, the diameter 5-10mm less than the diameter of lower pot body of aluminium sheet, even if being deformed by strong pressure bottom such design lower pot body, aluminium sheet is as well as bottom of pot body deformation do not ftracture (Fig. 5).

As shown in Figures 2 and 3, the thickness of 2 pots of walls of one lower pot body of outwardly convex at lower pot body 2 edge 5mm, upper pan body 1 edge chamfering 1 × 45 °, the external diameter of upper pan body 1 arrives 0.2mm than the internal diameter big 0 of lower pot body 2 high spot, upper pan body inserts lower pot body in an interference fit, by hydraulic test, upper pan body is pressed into lower pot body, so go up lower pot body fully to fit, then the edge at lower pot body uses argon arc welding welding, so lower pot body wrap pot design can with eliminate original butt welding mode weld suffered by shear stress, relatively become tension, it is greatly improved the overall bearing capacity of calandria, commissure is difficult to hydrops corrosion simultaneously, such as Fig. 4, on aluminium sheet, riveting has the screw for installing temperature control, such as Fig. 1.

Although below having made to elaborate to design and the example according to this utility model purpose referring to the drawings; but those of ordinary skill in the art will be consequently realised that; under the precondition limiting scope without departing from claim; still this utility model can be made various modifications and variations, and this modifications and variations still should belong to protection domain of the present utility model.
