Description
Technical field
Just detection type of coke drum is put on a suit of armour the formula insulation construction, belongs to chemical tower, tower wall heat-preserving equipment field, is specifically related to just detection type of a kind of coke drum and puts on a suit of armour the formula insulation construction.
Background technology
Coke drum is as a kind of thermal fatigue container, the shrinkage variation of expanding because its service temperature effect is often generated heat, cause its tower wall infringements such as drum, fatigue cracking often to occur, the therefore annual year that all needs STRENGTH ON COKE Tata wall weld seam to carry out the heat preservation pressure container is detected.For making the tower body surface temperature even, reduce temperature stress simultaneously, prevent that crackle from appearring in coke drum, need install insulation construction additional in the tower wall outside.At present the insulation construction that adopted of prior art is two braces structures, by the fixing lagging material of inside and outside two cover braces, corrugated panel is fixed on the outer braces protective effect again.This insulation construction complex structure needs first overall pulling down corrugated panel, outer braces and thermal insulation layer just can detect when detecting the tower wall, and complex steps detects inconvenience, and the not reproducible use of insulation construction after removing, cost height, the expense of taking a lot of work material.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, can expose weld seam fast, dismantle just detection type of coke drum easy to detect and put on a suit of armour the formula insulation construction.
The technical scheme that its technical problem that solves the utility model adopts is: this comprises interior braces, thermal insulation layer and corrugated panel, interior braces vertically evenly is layed in the tower wall outside, thermal insulation layer is fixed on the interior braces, it is characterized in that: on the weld seam of tower wall, following both sides are respectively equipped with, the lower support circle, on, lower support circle inboard is fixed on the interior braces, lateral external irradiation shape is evenly equipped with many support bars, on, many support bars on the lower support circle are symmetrical arranged, the outer end is provided with retaining plate, be fixed with extension spring on each bar support bar of lower support circle, the extension spring outside is with sleeve, the extension spring upper end is fixed with the sleeve top, sleeve lateral wall is connected with retaining plate, on, be fixed with a corrugated panel on two retaining plates that are oppositely arranged down.
Described upper and lower supporting cup is separately positioned on 100～200mm place, upper and lower both sides of weld seam.
Described each support bar bottom is equipped with supporting part.
Arrange with the fish scale shape between described corrugated panel, the right folded left side of the stupefied plate of adjacent left and right sides Habenaria dipionema Sohltr laminates installation, laminates installation under folding on the adjacent stupefied plate of Habenaria dipionema Sohltr up and down.
Described corrugated panel is connected by holding bolt with retaining plate.
It is all applicable to tower wall circumferential welded seam, longitudinal weld and skirt commissure that just detection type of this coke drum is put on a suit of armour the formula insulation construction.
Compared with prior art, the beneficial effect that the utility model had is: just detection type of this coke drum is put on a suit of armour the formula insulation construction does not have outer braces, simple in structure, and the corrugated panel of dismantling just can be seen thermal insulation layer; The corrugated panel burst is installed, and is for convenience detach, need not stop work and remove the integral heat insulation layer, only needs dismounting commissure corrugated panel and thermal insulation layer to detect; The corrugated panel of dismounting also can be reused economical with materials; The employing trip bolt is fixed, without electrosgas welding, unjointed steel braces structure decrease braces quantity, alleviated the load-bearing of equipment, and the detection at any time of the situation equipment that guaranteed to go into operation, can satisfy tower body heat expansion amount and require for convenience detachly to detect again.

Fig. 1～3rd, most preferred embodiment of the present utility model is described further below in conjunction with 1～3 pair of the utility model of accompanying drawing:
Embodiment
With reference to accompanying drawing 1～3:
Just detection type of this coke drum is put on a suit of armour the formula insulation construction and is made up of interior braces 1, thermal insulation layer 2, upper and lower supporting cup 6,8, support bar 7, retaining plate 5 and corrugated panel 12, and interior braces 1 vertically evenly is layed on tower wall 4 outsides, and the upper end is fixed by steel ring.Thermal insulation layer 2 is fixed on the interior braces 1 by bar for line.Coke Tata wall 4 is welded by the polylith doughnut-shaped steel plate, the 200mm place, weld seam 3 upper and lower both sides of tower wall 4 installs respectively, lower support circle 6,8, upper and lower supporting cup 6,8 inboards are fixed on the interior braces 1, lateral external irradiation shape is evenly equipped with many support bars 7, and support bar 7 bottoms are provided with the supporting part 11 of oblique support.Support bar 7 on the upper and lower supporting cup 6,8 is symmetrical arranged, and each support bar 7 passes thermal insulation layer 2, and mounting plate 5 on external part, fixes a corrugated panel 12 by holding bolt on upper and lower two retaining plates 5 that are oppositely arranged.12 of multi-disc corrugated panels that lay in the tower wall outside are arranged with the fish scale shape, and laterally adjacent stupefied plate 12 right-hand members of Habenaria dipionema Sohltr in the left and right sides is fixing at last overlap joint, the fixing at last overlap joint of the vertical neighbouring stupefied plate of Habenaria dipionema Sohltr 12 upper ends.Be fixed with extension spring 9 on the lower support bar, extension spring 9 outsides are with sleeve 10, and extension spring 9 upper ends and sleeve 10 top upper end covers are fixed, and sleeve 10 sidewalls are connected with retaining plate 5.When tower wall expanded by heating, extension spring 9 is drawn back, and reduces a part of swelling pressure of corrugated panel 12, satisfies the requirement of tower body heat expansion amount, increases insulation construction work-ing life.
Principle of work and working process are as follows:
When needs detect the tower body commissure, need not stop work, directly dismantling needs the outer field corrugated panel 12 of detection place, just can see thermal insulation layer 2, can detect behind the dismounting thermal insulation layer 2.Corrugated panel 12 adopts laminated structure, directly is fixed on the retaining plate with bolt, and replacing for convenience detach is than the large-scale chromemolybdenum steel suspender type thermal insulation structure of tradition excellence.Simultaneously, there is not whole outer braces restriction, needn't complete removal tower wall integral heat insulation layer, can overhaul, and dismounting corrugated panel 12 down still can utilize once more, dismantle, easy for installation flexible.This structure can be widely used in the welding line joint places such as circumferential welded seam, longitudinal weld and skirt weld seam of tower wall.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
