Metal pipe inner wall plastic spraying equipment and method

Abstract

The invention discloses a metal pipe inner wall plastic spraying equipment and method. The metal pipe inner wall plastic spraying equipment comprises a base. A powder absorption and recovery mechanism, a swing arm type material bearing mechanism and a high-pressure powder supply mechanism which are sequentially arranged from one end to the other end in the horizontal direction are on the base. Thehigh-pressure powder supply mechanism is used for providing high-pressure plastic spraying powder from one end of a metal pipe about to be subjected to plastic spraying to the inner wall of the metalpipe about to be subjected to plastic spraying. The powder absorption and recovery mechanism is used for carrying out powder absorption and recovery on the redundant high-pressure plastic spraying powder provided by the high-pressure powder supply mechanism from the other end of the metal pipe about to be subjected to plastic spraying. The swing arm type material bearing mechanism is used for providing the metal pipe about to be subjected to plastic spraying for the high-pressure powder supply mechanism and transferring the metal pipe with plastic spraying completed. By means of the equipment, manual operation is greatly reduced, inner plastic spraying work of metal pipes can be fast completed, time and labor are saved, and the production efficiency is greatly improved; and in addition, redundant plastic powder can be subjected to powder absorption and recovery through the powder absorption and recovery mechanism while inner plastic spraying is carried out on metal pipes, resources are saved, and environment pollution can be avoided.

Description

Technical field [0001] The present disclosure relates to the technical field of metal inner plastic pipe production, in particular to a plastic spraying equipment and method for the inner wall of a metal pipe. Background technique [0002] The metal inner plastic pipe uses seamless metal pipe and welded metal pipe as the base pipe, and the inner wall is coated with high adhesion, anti-corrosion, food-grade sanitary polyethylene powder coating or epoxy resin coating. The metal inner plastic pipe retains the rigidity and strength of the traditional metal pipe, and the metal inner plastic pipe is better than the plastic pipe than the aluminum plastic pipe. The metal inner plastic pipe has the characteristics of smooth inner wall, low friction resistance and no scaling. At the same time, the outer wall of the metal inner plastic pipe is more beautiful and luxurious. The metal inner plastic pipe has light weight, good toughness, impact resistance and high compressive strength, and it...

Problems solved by technology

[0003] However, at present, when the metal inner plastic pipe is processed, it is usually manually controlled, and it needs to be moved and supported manually. Moreover, the powder suction equipment is used in the inner wall spray technology, and the powder is sprayed by a fan, so it is impossible to remove the excess plastic powder. Recycling is time-consuming and labor-intensive, and the production efficiency is very low
