Problems solved by technology

[0005] The present invention has the following beneficial effects: due to the adoption of the above scheme, the stress system of the bottom plate is improved through the inverted conical tank bottom plate, and the vertical positive pressure is decomposed, so that the positive pressure causing the settlement deformation is reduced, and at the same time, the existing problems are solved. The problem of difficult emptying and venting of storage tanks; by using the bottom plate structure of anti-static composite rubber plate, the problems of large amount of steel plates on the bottom plate of the tank, heavy welding workload, and serious corrosion are solved, the construction process of the storage tank is simplified, and the labor intensity of workers is reduced. , and can prolong the service life of the storage tank and improve the economic benefits

Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing:

[0010] Depend on figure 1 As shown, a conical bottom plate of a composite rubber vertical storage tank includes a steel plate edge plate 2, and the steel plate edge plate 2 is a steel plate, which ensures the structural rigidity of the vertical storage tank and is also beneficial to the lift-off effect of the floating tank. It is not easy to damage the elephant feet caused by earthquakes; the composite rubber bottom plate has strong corrosion resistance, the material cost and construction cost are greatly reduced compared with the steel bottom plate, and the construction process is simplified at the same time. The medium plate 3 is in an inverted conical shape, and the slope i=a / b=0.03~0.05, which solves the existing problems of difficult emptying and venting of storage tanks; improves the stress system of the bottom plate, and the vertical positive pressure Decomposition ...

Abstract

The invention provides a composite rubber vertical storage tank conical bottom plate and a manufacturing method thereof. It mainly solves the problems that the existing vertical storage tank bottom plate steel plate consumption is large, the welding workload is large, complex anti-corrosion procedures are required before and after production, and the storage tank is difficult to empty and vent. It is characterized in that: the bottom plate is composed of a steel plate edge plate (2), an antistatic composite rubber edge plate (9), a middle plate (3), and a center plate (10). The middle plate (3) is in an inverted conical shape, surrounded by The slope toward the center is i=a / b=0.03-0.05. The invention has the characteristics of simple construction process of the storage tank, easy emptying and emptying of the storage tank, and long service life of the storage tank.

Description

Technical field: [0001] The invention relates to a vertical storage tank for oil field surface engineering, which belongs to a conical bottom plate of a composite rubber vertical storage tank and a manufacturing method thereof. Background technique: [0002] In oilfield surface engineering, storage tanks are essential equipment for liquid storage, among which vertical storage tanks are the most common form. The bottom plates of vertical storage tanks currently used are all steel plates, which are welded with a flat plate structure. The amount of steel plates is large, and the welding workload is heavy. The measures taken to prevent welding deformation are expensive, and the bottom of the tank must be checked before and after production. The steel plate undergoes complex anti-corrosion treatment, the construction process is complex, the labor intensity of the workers is high, and it is difficult to empty and vent the storage tank. The analysis and research data of the failur...
