Problems solved by technology

[0002] The existing metal double-wall detachable heat preservation cover has a wide application range, simple structure, very convenient installation and disassembly, is not easy to deform, and can be reused. However, the insulation layer used in the current metal double-wall detachable heat preservation cover is basically made of glass wool and Aluminum silicate fiber and glass wool are not suitable for direct use in actual use. If they are forced to be used directly, they will have a certain impact on the surrounding environment, and may easily cause skin itching or respiratory allergies; while choosing aluminum silicate fiber, there is a cost. High cost, relatively poor compressive and flexural strength, easy to generate dust, poor waterproof performance and other defects

Abstract

The invention provides a metal double-wall dismountable thermal insulation cover and a manufacturing method. The metal double-wall dismountable thermal insulation cover mainly comprises a metal outer shell and an inner thermal insulation layer, wherein the metal outer shell is a block-shaped box body formed by four side wall boards, an outer wall board and an inner wall board, fireproof bricks are arranged inside the block-shaped box body in an overlaying mode, fill the inner cavity of the block-shaped box body and form at least two parallel layers between the outer wall board and the inner wall board which are opposite, the outer wall board and the inner wall board correspondingly form an arc-shaped board, and an inner supporting frame is arranged inside the block-shaped box body and connect the four side wall boards, the outer wall board and the inner wall board. The manufacturing method comprises the following steps of selecting materials, cutting components, blanking, presetting the fireproof bricks, fixedly arranging the inner supporting frame through spot welding, respectively and fixedly arranging the four side wall boards and the outer wall board on the inner supporting frame through group spot welding, fill the inner supporting frame with the fireproof bricks and fixing, and group-riveting the inner wall board and the supporting frame to form the block-shaped box body.
