Description
Technical field
The utility model relates to the making of zirconium equipment stiffening ring bearing, especially removable stiffening ring ear seat on the zirconium equipment.
Background technology
When container diameter larger, housing is thinner, and external load (comprise quality, wind carry, earthquake load etc.) is larger, when perhaps being in negative-pressure operation in the housing, the local stress that adopts common hanging support often to make housing is large, distortion is larger, even can cause unstability.In the case, should adopt with two the circle stiffening rings ear seat (hanging support).The backing plate of common stiffening ring ear seat is identical with the shell material of equipment with two circle stiffening ring materials.If the apparatus casing material is the non-metals zirconium, the material of the backing plate of bearing and two circle stiffening rings also is zirconium, and zirconium material price is more expensive, and the manufacturing cost of equipment will increase greatly like this.So stiffening ring ear seat is designed to removablely on zirconium equipment, the material of the backing plate of bearing and two circle stiffening rings does not just need identical with shell material, above the ear seat back-up ring is set, and so neither impact is used, and can reduce cost again.
The utility model content
The utility model purpose is: propose removable stiffening ring ear seat on a kind of zirconium equipment, can reduce the zirconium material use quantity, save cost.
Technical solutions of the utility model are: removable stiffening ring ear seat on the zirconium equipment comprises backing plate, ear seat base plate, ear seat gusset, stiffening ring cover plate, zirconium back-up ring, back-up ring gusset, stiffening ring base plate, PTFE dielectric film, bolt, nut, packing ring and connecting panel; At zirconium equipment periphery welding two circle zirconium back-up rings, fixing some zirconium gussets in the middle of two circle zirconium back-up rings, back-up ring and gusset and the welding of zirconium apparatus casing, the bottom of two circle zirconium back-up rings is provided with stiffening ring cover plate and the stiffening ring base plate of hoop letter zirconium equipment periphery; Stiffening ring cover plate and stiffening ring base plate all are to be made of two rigidity semi-ring cover plates and two rigidity semi-ring base plates, two rigidity semi-ring cover plates and two rigidity semi-ring back plate connections are fixed with connecting panel, two connecting panels are connected by the bolt and nut packing ring, are lined with the PTFE dielectric film between stiffening ring cover plate and stiffening ring base plate and the zirconium apparatus casing; Be provided with ear seat base plate and ear seat gusset between stiffening ring cover plate and the stiffening ring base plate.
Back-up ring and gusset size can be calculated to determine according to the weld strength in " chemical plant mechanical design handbook ".Why in the middle of two circle back-up rings, increase gusset; although be because zirconium has good welding performance; but zirconium is very active metal; zirconium and zircaloy have very strong affinity to the hydrogen in the environment, oxygen, nitrogen; particularly at high temperature; zirconium easily with above-mentioned gas generation chemical reaction, and then cause the fragility of zirconium weld seam, rupture than being easier to.Just there is not this problem in the titanium weld seam on the titanium equipment, gets final product so the removable stiffening ring ear seat top on the titanium equipment only needs to increase some locatings plate.And on the zirconium equipment, because the defective of weld seam, when making removable stiffening ring, two circle back-up ring intermediate demands of its top increase some gussets, guarantee weld strength.Stiffening ring ear seat is made into removable,
Stiffening ring ear seat material design is carbon steel, and circle back-up ring of two on it and gusset are designed to the zirconium plate, and one deck PTFE is set between backing plate and housing, avoid carbon steel directly to contact with the zirconium plate, prevent iron contamination.Such structure can reduce the zirconium material use quantity, and then reduces manufacturing cost.
The beneficial effects of the utility model are: in the middle of the two circle back-up rings above removable stiffening ring gusset is set, overcomes the defective of weld seam fragility on the zirconium equipment, guarantee weld strength.This removable stiffening ring uses on zirconium equipment, and is easy to use, cost is low.Hanging support is applicable to device diameters and is not more than 4m, and device height is not more than the vertical vessel of 10m, and the stiffening ring bearing is a kind of structure that forms on the basis of hanging support, but can not be subjected to the restriction of this condition.Be the equipment of non-ferrous metal material for apparatus casing, such as zirconium equipment, stiffening ring ear seat made removable, increase above it the structure of back-up ring and gusset.So neither affect its use, can greatly reduce manufacturing cost again, realize economy.
Description of drawings
Fig. 1 is the making structural representation of removable stiffening ring ear seat on the zirconium equipment.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the block construction scheme drawing of pin.
The specific embodiment
Below in conjunction with accompanying drawing the utility model specific embodiment is described.
Among the figure, 1 backing plate; 2 ear seat base plates; 3 ear seat gussets; 4 stiffening ring cover plates; 5 back-up rings; 6 back-up ring gussets; 7 stiffening ring base plates; 8PTFE; 9 bolts; 10 nuts; 11 packing rings; 12 connecting panels; 13 pins.
At first determine the specification of stiffening ring ear seat, and the size of back-up ring and gusset.The backing plate of this stiffening ring is comprised of two parts, and these two parts have connecting panel, bolt, nut and pin to be connected.Stiffening ring ear seat material design is carbon steel, and circle back-up ring of two on it and gusset are designed to the zirconium plate, and one deck PTFE is set between backing plate and housing, avoid carbon steel directly to contact with zirconium.Prevent iron contamination.
Above removable stiffening ring ear seat, increase by two circle back-up ring structures, in the middle of two circle back-up rings, increase some gussets, back-up ring and gusset and housing welding.Back-up ring welds mutually with housing, because the fragility of zirconium weld seam than being easier to fracture, so increase some gussets in the middle of back-up ring, overcoming the fragility of weld seam, the defective of easy fracture, and then guarantees weld strength.
Removable stiffening ring ear seat comprises backing plate on the zirconium equipment; Ear seat base plate; Ear seat gusset; The stiffening ring cover plate; The zirconium back-up ring; The back-up ring gusset; The stiffening ring base plate; The PTFE dielectric film; Bolt; Nut; Packing ring; Connecting panel; Pin.At zirconium equipment periphery welding two circle zirconium back-up rings, fixing some zirconium gussets in the middle of two circle zirconium back-up rings, back-up ring and gusset and the welding of zirconium apparatus casing, the bottom of two circle zirconium back-up rings is provided with stiffening ring cover plate and stiffening ring base plate; Stiffening ring cover plate and stiffening ring base plate all are to be made of two rigidity semi-ring cover plates and two rigidity semi-ring base plates, two rigidity semi-ring cover plates and two rigidity semi-ring back plate connections are fixed with connecting panel, two connecting panels are connected by the bolt and nut packing ring, are lined with the PTFE dielectric film between stiffening ring cover plate and stiffening ring base plate and the zirconium apparatus casing; Be provided with ear seat base plate and ear seat gusset between stiffening ring cover plate and the stiffening ring base plate.
