[0007] 2) Although it has undergone orthopedic treatment, during the single-chamber hydrostatic test, the cylinder also has a large deformation
It can be foreseen that in the later stage of production and use, there are single chambers on both sides, which directly bear high pressure, the weld seam is unevenly stressed, and the weld seam is easy to tear and cause cracks, which will cause the media on both sides to mix and affect the use function of the storage tank. , and affect production, there is a risk of environmental pollution

The invention discloses a multi-cavity storage tank cavity separation plate reinforcement structure. The multi-cavity storage tank cavity separation plate reinforcement structure comprises a steel vertical storage tank barrel body, a stand column, a cavity separation plate, arc-shaped rib plates and a reinforcement device, wherein the stand column is vertically arranged in the steel vertical storage tank barrel body, the S-shaped cavity separation plate is arranged on the side wall of the stand column, a plurality of the arc-shaped rib plates are arranged on two side walls of the S-shaped cavity separation plate, the reinforcement device comprises a base plate and a support plate, the base plate is arranged on the inner wall of the steel vertical storage tank barrel body, tail ends of thecavity separation plate and the arc-shaped rib plates are welded on the base plate, one end of the support plate is vertically welded onto the S-shaped cavity separation plate, the other end of the support plate is welded onto the base plate, the support plate, the S-shaped cavity separation plate and the steel vertical storage tank barrel body form a triangular structure, and therefore loading capacity is strengthened, welding joints are protected, the normal use of a multi-cavity storage tank is guaranteed, and the service life of the multi-cavity storage tank is prolonged.
Description
technical field [0001] The invention belongs to the technical field of chemical storage tanks, and in particular relates to a multi-chamber storage tank sub-chamber reinforcement structure and a construction process. Background technique [0002] As an important equipment in chemical, coating and pharmaceutical production, steel storage tanks have been widely used in chemical, coating and pharmaceutical industries. The main types are vertical storage tanks, horizontal storage tanks, spherical storage tanks, etc. Commonly used steel storage tanks are generally single-cavity storage tanks. When storing two or more materials, multiple storage tanks are required, supplemented by related pipelines for piping connections, which will lead to high engineering manufacturing costs and occupy Disadvantages of large venue area. [0003] Multi-chamber storage tank is a new type of storage tank that has emerged in recent years. The tank body is divided into two or more independent cavit...
