Description
Technical field
The invention belongs to high temperature silo design technical field, and in particular to a kind of high temperature feed bin expansion joint.
Background technology
Universal expansion joint is traditionally also being compensator, or telescopic joint, by the bellows for forming its operative body（It is a kind of
Flexible member）Formed with annexes such as end pipe, stent, flange, conduits.Expansion joint is to compensate for because temperature difference and mechanical oscillation are drawn
The additional stress risen, and a kind of flexible structure being arranged on container casing or pipeline.Utilize having for its operative body bellows
Dilatation is imitated, with absorption line, conduit, container etc. by the change in size reason such as expanding with heat and contract with cold and produce, or compensation pipes,
The axial of conduit, container etc., transverse direction and angular displacement；It can also be used on noise-and-vibration-reduction and heat supply, in order to prevent heat supply pipeline liter
Wen Shi, pipe deforming or destruction is caused due to thermal stretching or temperature stress, it is necessary to set compensator on pipeline, to compensate pipe
The thermal stretching in road, so as to reduce the stress of tube wall and act on the active force on valve member or supporting structure.
Feed bin is the container for storing material, is usually steel construction or reinforced concrete structure.The geometry of feed bin：Top
It is cylindrical or prismatic mostly, lower part is punctured into the conical hopper for being provided with discharge port.Material is by conducting oneself with dignity from bottom discharge in storehouse
Mouth draws off transhipment.High temperature feed bin is on the basis of normal steel structure feed bin, and high-temperature-resistant layer or guarantor are added in or beyond bin wall
Warm layer, allows feed bin to bear high temperature and can store the container of high-temperature material.
High temperature feed bin bulkhead structure is divided into inside holding or external thermal insulation structure.It is insulating layer in the general bulkhead steel plate of thermal structure
And flame retardant coating, to bear the high temperature of high-temperature material and abrasion, also there is the situation that heat-resisting steel liner plate is laid with fire resisting layer surface.In it is low
Warm structure directly contacts high-temperature material for bulkhead steel construction, bears the abrasion of material, the certain thickness thermal insulating material of bulkhead outer cladding
Material, to ensure temperature of charge, reduces feed bin heat and scatters and disappears, ensure perimeter security.Internal insulation structure is to prevent furnace wall heat expansion repeatedly
Shrinkage is cracked, and usual every meter of length should stay 5-6mm dilatation joints, and dilatation joint should stagger between each layer, and fire resisting fibre is inserted in seam
Dimension or the mortar mixed with 25-30% asbestos.But most of feed bin while high temperature is born, adds all just for high-temperature process
High-temperature-resistant layer and insulating layer can bring the flexible inconsistent of feed bin steel construction and high-temperature-resistant layer because of expanding with heat and contract with cold for feed bin so that
Stress is produced, the situation for causing feed bin to destroy, high temperature feed bin is asynchronous because expanding, and can influence the leakproofness of equipment, feed bin occurs
The leakage of middle fuel gas, there are security risk.
