Abstract
The utility model provides a cauldron is personally experienced sth. Part of body, and tantalum is taken over and connection structure on layer is answered to cauldron body tantalum in order to stretch in tantalum steel composite sheet equipment, it includes stretch tub (1) in the tantalum, to stretch tub one end of (1) in this tantalum of and fix in flange (2) are taken over to the carbon steel, the carbon steel is taken over flange (2) and is fixed on the carbon steel layer of tantalum composite sheet casing (3) surface characterized by the tantalum in stretch tub (1) stretch into in the tantalum composite sheet casing (3) one end through tantalum flanged plate (5) that have circular -arc -transition structure (4) realize with the tantalum layer sealing connection of tantalum composite sheet casing (3) internal surface, stretching tub skin weld of (1) in the turn -ups of tantalum flanged plate (5) part and the tantalum and linking to each other, the plate part of tantalum flanged plate (5) links to each other with the welding of the tantalum layer of tantalum composite sheet casing (3) internal surface. The utility model discloses simple structure, it is convenient to make.
Description
Technical field
This utility model relates to a kind of chemical device, the joint pipe structure of the tantalum steel composite material reactor of especially a kind of good corrosion resistance, and specifically a kind of kettle is the attachment structure stretching tantalum adapter in tantalum steel composite board equipment with kettle tantalum cladding.
Background technology
It is known that, tantalum metal is that a kind of resistance to strong acid corrodes extraordinary rare metallic material, but expensive, to the only adaptable splendid attire strong corrosive media of tantalum material equipment, as adopted pure tantalum material manufacture, the cost of equipment is by much more expensive, therefore, tantalum material uses only as the anti-corrosion lining of equipment, and thickness generally ratio is relatively thin, only 1 millimeter, uses carbon steel to ensure the intensity of equipment as basic unit. owing to tantalum material directly cannot weld with carbon steel, the sheet material therefore manufacturing equipment kettle must adopt the method for Explosion composite to be formed, but the import and export of kettle adapter must adopt welding just can carry out, and this is necessary for carrying out the welding of same material. owing to the reaction mass in tantalum steel composite material reactor is strong corrosive medium, therefore it is required that the position that its inlet/outlet pipe contacts with medium also must adopt tantalum pipe, require that connecting tube stretches into the part within kettle and is necessary for tantalum pipe, the sealing that tantalum pipe must be fixed after stretching into kettle, that is need to be welded with inner wall of kettle by tantalum pipe with tantalum plate, way conventional at present is to realize the connection of tantalum pipe and kettle with direct right-angle transition plate, that is it is directly perforate on tantalum plate, by Kong Bianyu tantalum, this is weldingly connected again, not only soldering angle is big, and require height, simultaneously because tantalum plate is very thin, easily cause damage during welding and not easily find, and this right-angle structure easily causes stress and concentrates, during equipment uses, weld seam is easily generated fatigue crack, affect service life.
Utility model content
The purpose of this utility model is to adopt directly adapter welding to easily cause the problem that stress is concentrated and damaged for existing tantalum inside extending tube, designs a kind of attachment structure with in-flanges.
The technical solution of the utility model is:
A kind of kettle is the attachment structure stretching tantalum adapter in tantalum steel composite board equipment with kettle tantalum cladding, it includes tantalum inside extending tube 1, one end of this tantalum inside extending tube 1 is fixed in carbon steel pipe connecting flange 2, carbon steel pipe connecting flange 2 is fixed in the carbon steel layer of tantalum composite plate housing 3 outer surface, it is characterized in that one end that described tantalum inside extending tube 1 stretches in tantalum composite plate housing 3 is tightly connected by the tantalum layer realized with tantalum composite plate housing 3 inner surface with the tantalum flanged plate 5 of arc transition structure 4, the flange part of described tantalum flanged plate 5 is connected with the surface soldered of tantalum inside extending tube 1, the tantalum layer of the plate part of tantalum flanged plate 5 and tantalum composite plate housing 3 inner surface is weldingly connected.
Packing ring 6 is added between the plate part and the carbon steel part of tantalum composite plate housing 3 of tantalum flanged plate 5.
The optimum height of the flange boss of tantalum flanged plate 5 is 10-30 millimeter.
The beneficial effects of the utility model:
This utility model is by changing by right-angle side as the turnup structure of arc transition into, and the stress decreasing welding position is concentrated, and substantially prolongs the service life of flanged plate.
This utility model simple in construction, easily manufactured.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 7 is leak detection mouth, and 8 is silver brazing weld seam, and 9 is tantalum lining pad.
Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figure 1.
A kind of kettle is the attachment structure stretching tantalum adapter in tantalum steel composite board equipment with kettle tantalum cladding, it includes tantalum inside extending tube 1, one end of this tantalum inside extending tube 1 is fixed in carbon steel pipe connecting flange 2, carbon steel pipe connecting flange 2 is fixed in the carbon steel layer of tantalum composite plate housing 3 outer surface, one end that described tantalum inside extending tube 1 stretches in tantalum composite plate housing 3 is tightly connected by the tantalum layer realized with tantalum composite plate housing 3 inner surface with the tantalum flanged plate 5 of arc transition structure 4, the flange part of described tantalum flanged plate 5 is connected with the surface soldered of tantalum inside extending tube 1, the tantalum layer of the plate part of tantalum flanged plate 5 and tantalum composite plate housing 3 inner surface is weldingly connected, the optimum height of the flange boss of tantalum flanged plate 5 is 10-30 millimeter, packing ring 6 is added between the plate part and the carbon steel part of tantalum composite plate housing 3 of tantalum flanged plate 5. as it is shown in figure 1, be also associated with leak detection mouth 7 between tantalum inside extending tube and carbon steel pipe connecting flange, if damaging occurs in tantalum inside extending tube 1, then first leakage fluid can ooze out from leak detection mouth 7.
This utility model is not directed to part and all same as the prior art prior art maybe can be adopted to be realized.
