Abstract
The invention discloses support structures of an inner tank of a heavy jacketed low-temperature deep cooling storage tank. The inner tank of the storage tank is suspended from the inner wall of an external tank through three hanging strips. One end of the hanging strip is circumferentially and evenly fixed on the external wall of a bottom seal head of the inner tank, and the other end is circumferentially and evenly fixed on the inner wall of the external tank. The upper part and the lower part between the inner tank and the external tank of the storage tank are circumferentially and evenly provided with at least three support structures. Each support structure comprises a pair of clamping plates, a fixed ring and a support post, wherein the clamping plates are fixed on the external wall of the inner tank and are parallel to the axial direction of the storage tank; the fixed ring is fixed on the inner wall of the external tank; and the support post is arranged between the clamping plates and the fixed ring, is perpendicular to the external wall of the inner tank and the inner wall of the external tank, and is arranged between the external wall of the inner tank and the inner wall of the external tank. The support structures are applicable to the heavy jacketed low-temperature deep cooling storage tank.
Description
Technical field
The invention belongs to the structure field of tank of heavy jacketed low-temperature deep refrigerant storage, refer more particularly to the interior jar of tank of heavy jacketed low-temperature deep refrigerant storage and the supporting construction between the outer jar.
Background technology
Conventional low-temperature deep basin, as shown in Figure 7, jar 2 fixedly is to adopt the bottom steel pipe to support to add top drawstring structure in it, as shown in Figure 9, jar 1 bottom (head) is interior along the circumferentially even some steel pipes 3 of vertical position welding outside, and then, interior jar 2 is supported on outer jar 1 bottom (head) by steel pipe 3 with interior jar 2 and the welding of steel pipe 3 other ends; Transportation safety when droping to the ground for interior jar 2 for assurance simultaneously as shown in Figure 8, circumferentially welds some band steel drawstrings 4 at interior jar of 2 top cylindrical shells, and interior jar 2 upper ends are hung on outer jar 1 upper end.In this structure between jar 2 and the outer jar 1 fixedly is rigid constraint, under service conditions, interior jar 2 operating temperatures are subzero about 196 ℃ ultralow temperature, outer jar 1 operating temperature is a normal temperature, temperature deformation is inharmonious between the inside and outside jar of existence, produce local temperature difference stress at the inside and outside jar of position that is rigidly connected, all of interior jar 2 are stressed all to be to be delivered to outer jar 1 by point of connection, thereby there is great stress concentration in the point of connection place at inside and outside jar, when this stress surpasses the strength limit of material, will cause device damage, because the vacuum interlayer space in support fixed structure is between jar 2 and the outer jar 1, usual at all can't monitor stress concentrate and cause the situation of material deformation, only remain to be found after device damage lost efficacy, so it is very huge to the basin potential hazard.
Summary of the invention
Technical matters to be solved by this invention is: will provide a kind of and can guarantee outer jar of internally effective support of jar, and avoid the supporting construction of the interior jar of inside and outside jar of tank of heavy jacketed low-temperature deep refrigerant storage that supports to produce thermal (temperature difference) stress again.
For addressing the above problem, the technical solution used in the present invention is: interior jar supporting construction of tank of heavy jacketed low-temperature deep refrigerant storage, basin interior jar by at least three strip suspension inwall outside jar, one end of described suspender belt is along circumferentially evenly being fixed on the bottom bulkhead outer wall of interior jar, the other end is along circumferentially evenly being fixed on the inwall of outer jar, upper and lower between the interior jar of basin and outer jar, respectively along circumferentially evenly being provided with at least three place's supporting constructions, every place supporting construction comprises: a pair of clamping plate in being fixed on the tank wall, be fixed in outer jar on the inwall set collar and be positioned over pillar stiffener between a pair of clamping plate and the set collar, the axially parallel of described clamping plate and basin, described pillar stiffener is perpendicular to interior tank wall and outer jar inwall, and pillar stiffener is arranged between interior tank wall and the outer jar inwall.
Described suspender belt is the heavy band steel suspender belt of corrosion-resistant steel.
Described pillar stiffener is an epoxy glass steel pipe pillar stiffener, and described set collar is fixing with outer jar of inwall welding, and described clamping plate and the welding of interior tank wall are fixing.
The junction of described outer jar inwall and suspender belt also is welded with heavier-duty suspender belt seat, and described heavier-duty suspender belt seat one side is fixing with outer jar of inwall welding, and another side and suspender belt welding are fixing.
The invention has the beneficial effects as follows: the present invention adopts advanced " suspender belt+glass-felt plastic supports " mode, under the equipment normal upright station, the gravity loading of interior jar and medium for storing thereof is delivered on outer jar by suspender belt, finally be delivered on outer jar supporting leg and the Equipment Foundations, avoid producing extra eccentric moment load; Equipment is in when droping to the ground transportation, and is fixing with interior jar by the fiber glass epoxy pillar stiffener, guarantees transportation safety; The needs of the interior down jar free shrink of worst cold case had been avoided conventional fixed support structure because the inconsistent generation that causes stress raisers, device damage situation of temperature deformation when this structure had ensured equipment work simultaneously; The coefficient of thermal conductivity of the epoxy glass steel pipe pillar stiffener that adopts in this structure is about stainless 1/30, suspender belt length is the twice that conventional steel pipe supports, the overall leaking heat of COMPREHENSIVE CALCULATING compare facilities adds drawstring structure low about 15% than conventional steel pipe supporting leg, guaranteed the reliability of equipment intensity and the minimum leaking heat of equipment, equipment has higher reliability and advance.
