Embodiment 1

[0016] A metal skirt integrally wound with a glass fiber reinforced plastic tank, which includes: a skirt cylinder, a skirt bottom plate, a skirt cone and a supporting rib, and the skirt cylinder, skirt bottom plate and skirt cone The support ribs are welded into one body, the skirt bottom plate has anchor bolt holes, and the skirt cylinder has manholes for inspection.

[0017] The installation method of the above-mentioned metal skirt includes the following steps:

[0018] (1) The head of the FRP base is installed inside the metal skirt, and the head of the FRP base is bonded and fixed to the cone of the skirt;

[0019] (2) The skirt bottom plate is installed with a winding bracket;

[0020] (3) The glass fiber reinforced plastic base head with metal skirt is horizontally docked with the glass fiber reinforced plastic tank;

[0021] (4) The glass fiber reinforced plastic tank body and the metal skirt seat are controlled by a computer and are wound and reinforced as a whole....

Abstract

The invention discloses a metallic skirt capable of being integrally wound with a glass fiber reinforced plastics tank. The metallic skirt is characterized by comprising a skirt cylinder, a skirt baseplate, a skirt cone and supporting rib plates, wherein the skirt cylinder, the skirt base plate and the skirt cone are integrally welded through the supporting rib plates, foundation bolt holes are formed in the skirt base plate, and an inspection manhole is formed in the skirt cylinder. Compared with the prior art, the structural design is reasonable, the fitting degree of the skirt cone and a glass fiber reinforced plastics base end socket is higher, and stress is uniformly borne. The metallic skirt and the glass fiber reinforced plastics tank are integrally wound, and the circumferential strength of a material at the connection position is up to 300 MPa and is two times as high as the strength of a traditional hand lay-up material. The glass fiber reinforced plastics base end socket isin butted connection with the metallic skirt in advance, and compared with the way that the manufactured glass fiber reinforced plastics storage tank is in butted connection with the metallic skirt,because the butted connection body is smaller, the cost of a hoist is saved, and the butted connection accuracy is more easily ensured.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a metal skirt integrally wound with a glass fiber reinforced plastic tank body and an installation method thereof. Background technique [0002] FRP storage tanks with metal skirts are usually hand-laid up vertically with the metal skirt after the FRP storage tank is manufactured. The strength of the hand-laid-up molding material is low, and sufficient butt joint thickness and width are required to ensure the connection strength; several pieces are independent of each other. The matching degree between the pre-embedded plate connected with the skirt seat and the base head is poor, resulting in uneven force on the base head; when the FRP tank is wound, one end of the base head needs to be bonded with a winding bracket, and it needs to be removed after the winding is completed. The process is complicated and produces Unnecessary auxiliary costs; vertical docking requires crane ...
