Abstract
The utility model discloses a kind of buried horizontal tank top opening protective devices, are mainly made of sleeve, corrugated plating cone cylinder and adapter tube；Sleeve is set in adapter tube outside, and the two coaxial arrangement is connected by corrugated plating cone cylinder between sleeve upper end and adapter tube outer wall, forms annular space between sleeve lining and adapter tube outer wall；Sleeve bottom is equipped with annular resilient bottom plate.The additional force acted on adapter tube and moment of flexure can be effectively reduced in the utility model, avoid adapter tube itself and adapter tube that strength failure or fatigue rupture occurs with cylinder junction.
Description
Technical field
The utility model relates to the protection facilities of tank top opening, relate in particular to a kind of buried horizontal tank top
Opening protection device.
Background technique
Chinese patent CN201520554527.9 discloses a kind of liquid hydrocarbon storage device using buried horizontal tank, storage
On the basis of tank places pile foundation or casting bed, tank body is covered by overburden layer, and the top of tank body is equipped with manhole, and technique interface tube is opened
Opening, the mouthpieces such as mouth well stretch out overburden layer.Above-mentioned buried horizontal tank exists following insufficient: (1) when charging, blowdown or
Person's low-temperature storage, tank body heating, cooling will cause storage tank and axial elongation or contraction occur in length direction；(2) storage tank it is long when
Between be on active service, basis certain nonuniform settlement can occur, to cause tank body bending deformation；(3) when earthquake occurs, the movement on ground
It will cause earthing to act on mouthpiece random shock.Under above-mentioned factor effect, tank body earthing can be produced tank body upper opening
Raw biggish additional force and moment of flexure easily cause mouthpiece itself or mouthpiece and storage tank junction generation strength failure or tired
Labor is destroyed, to cause the leakage of tank inside medium, and due to storage tank earthing, mouthpiece is not easy to examine with storage tank junction
It surveys, more aggravates the presence of risk.Conventional design method by being uniformly arranged diagonal brace in adapter tube surrounding, and increase adapter tube wall thickness with
To improve the bearing capacity of opening, the above method has the following problems local cylinder wall thickness: (1) by setting diagonal brace, increasing
The rigidity of adapter tube, but when receiving earthing additional load, diagonal brace is excessive with cylinder junction and with adapter tube junction local stress,
The effect of tank body hot and cold alternation or the variation of foundation uneven settlement, easily cause diagonal brace and cylinder junction and with adapter tube junction
Strength failure or fatigue rupture occurs；(2) diagonal brace supports, and earthing butt tube random shock acts on when not resisting earthquake；(3) by
It is equipped with diagonal brace in mouthpiece, adapter tube outer wall is not easy that protective layer is arranged, if there is sharp hard object in earthing, easily causes adapter tube outer
Wall erosion resistant coating is pierced through by sharp hard object, corrosion failure occurs, to weaken its bearing capacity；(4) diagonal brace and adapter tube welding connect
It connects, replacement not easy to disassemble, contacts friction with earthing for a long time, easily corrode, bearing capacity is difficult to ensure.
Utility model content
Strength failure or fatigue rupture easily occurs in order to solve adapter tube receiving earthing additional load of the existing technology, connects
The pipe outer wall technical problem inconvenient there are corrosion risk and maintenance, the utility model provide a kind of buried horizontal tank top
Opening protection device.
Buried horizontal tank top opening protective device provided by the utility model mainly by sleeve, corrugated plating cone cylinder and connects
Pipe composition；Sleeve is set in adapter tube outside, and the two coaxial arrangement is connected between sleeve upper end and adapter tube outer wall by corrugated plating cone cylinder
It connects, forms annular space between sleeve lining and adapter tube outer wall；Sleeve bottom is equipped with annular resilient bottom plate.
The annular resilient bottom plate can be made of rubber sheet gasket or corrugated plating or high density polyethylene (HDPE).
The sleeve is spliced by two semicircular cylinders, easy to disassemble.The optional various wear-and corrosion-resistant materials of sleeve material, packet
Metal and nonmetallic materials are included, metal material outer surface need to apply anticorrosive paint or using corrosion resistant alloy, the optional pottery of nonmetallic materials
Porcelain, plastics or polyester, such as glass reinforced plastic or reinforced epoxy material, certainly it is also an option that other suitable materials.
The corrugated plating cone cylinder can be rolled using stainless steel or the carbon steel corrugated plating with erosion resistant coating.
Using the utility model, have it is following the utility model has the advantages that
(1) when horizontal tank due to expanding with heat and contract with cold, when foundation settlement, with earthing relative displacement, earthing load occur for adapter tube
Effect moves horizontally sleeve or lateral bending, due to being along the circumferential direction uniformly provided with corrugated plating cone cylinder, ripple between sleeve and adapter tube
Plate cone cylinder can absorb all directions and largely deform, and effectively reduce the additional force acted on adapter tube and moment of flexure, avoid adapter tube originally
Body and adapter tube and cylinder junction generation strength failure or fatigue rupture；
(2) when an earthquake occurs, corrugated plating cone cylinder has vibration damping and energy-absorbing effect, and earthing is effectively reduced and rushes to storage tank adapter tube
The effect of hitting；
(3) casing uses wear-and corrosion-resistant material, has excellent resistance to corrosion, makes mouthpiece is not direct to connect with earthing
Touching can effectively avoid overburden layer to hard object docking tube outer surface damage sharp in its corrosiveness and earthing；
(4) casing is detachable part, in maintenance, can be replaced according to practical corrosion or damaged condition；
(5) casing top is equipped with corrugated plating cone cylinder, can prevent rainwater from entering in sleeve, avoid adapter tube outer wall corrosion.
The utility model can be used for storing liquid hydrocarbon large-scale earthing formula tank top opening, as manhole, technique opening with
And the protection structure of open well, it is equally applicable to buried horizontal vessel top opening protection in petroleum refining, chemical industry or gas station.
