Preparation method of bamboo winding composite vertical storage tank

Abstract

The invention relates to a preparation method for a bamboo coiled composite vertical type storage tank. The preparation method is characterized by comprising the following steps: preparing an end socket lining layer, an end socket enhancement layer and an outer protection layer in sequence so as to prepare a top end socket, then directly forming a tank bottom plane on the basis of a plane, manufacturing a storage tank main body, fixing the top end socket of the storage tank at the upper end of a matched storage tank main body die, preparing a storage tank main body lining layer, enabling the storage tank main body die to rotate around the axial line, enabling a coiling trolley to do up-and-down reciprocating motion in a rail, tidily arraying and coiling bamboo split rolls outside the storage tank main body lining layer and a combination part of the storage tank main body and the top end socket of the storage tank by virtue of relative motion between the storage tank main body lining layer and the top end socket of the storage tank, adding a resin mixture during coiling, performing solidification to form the storage tank main body enhancement layer, and finally coating the outer protection layer; sealing the inner side and outer side of the combination part of the tank bottom and the main body by virtue of resin and bamboo fiber non-woven cloth, pasting an arc transition region, and coating another outer protection layer after solidification is finished. The method is low in cost, environment-friendly in process and high in product quality.

Description

technical field [0001] The invention relates to a preparation method of a bamboo winding composite vertical storage tank, which belongs to the application field of large-diameter pressure vessels. Background technique [0002] In recent years, my country's economy has continued to grow rapidly, bringing good opportunities for the application of large-diameter containers in the market. Especially in petrochemical, light industry, energy, aerospace and other fields are widely used. Large vessels can be divided into four categories in terms of structure: the first category is all-metal vessels; the second category is metal-lined hoop-wound composite-reinforced composite pressure vessels; the third category is fully-wound composite vertical storage vessels. Tanks are the main manifestation of large containers; the fourth category is plastic-lined fully wound composite reinforced composite pressure vessels. [0003] Because the composite container not only takes into account th...
