Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot sequentially limit the protection scope of the present invention.

[0021] A suspended steel pipe external plastic coating powder recovery integrated spraying production line, including a base 14, a frame 12, a powder coating mobile box 5, a powder coating mobile box moving device, a steel pipe conduction frame and a steel pipe support frame. The steel pipe coming out of the preheating furnace moves to the steel pipe support frame, which supports the steel pipe from both ends and rotates at the same time. The powder coating moving box moving device passes the powder coating moving box through the outer surface of the steel pipe to spray the outer surface of the steel pipe. The specific structure is as follows:

[0022] The frame is installed on the base,...

Abstract

The invention relates to a suspended steel tube externally sprayed plastic powder recovery integrated spraying production line. The suspended steel tube externally sprayed plastic powder recovery integrated spraying production line comprises a base, a rack, a powder spraying moving box, a powder spraying moving box moving device, a steel tube conducting rack and a steel tube supporting rack, wherein the steel tube conducting rack drives a steel tube from a preheating furnace to move to the steel tube supporting rack; the steel tube supporting rack supports the steel tube from two ends and rotates at the same time; the powder spraying moving box moving device drives the powder spraying moving box to pass from the outer surface of the steel tube to spray the outer surface of the steel tube.The side wall of the spraying box in the production line provided by the invention is of double layers, a through hole is formed in the lower portion of the inner side of the box body, and residual powder after spraying can be recovered to the powder spraying box through a recovery isolating layer, so that powder is fully recycled, and the raw materials are saved.

Description

technical field [0001] The invention belongs to the field of plastic coating of steel pipes, in particular to a suspended steel pipe external plastic coating powder recycling integrated spraying production line. Background technique [0002] At present, plastic-coated steel pipe is a new type of high-efficiency anti-corrosion steel, which has excellent anti-corrosion performance, high compressive strength, long service life, smooth inner surface, good liquid flow performance, etc., making it quickly recognized by the market. Plastic-coated steel pipes are formed by melting a layer of polyethylene resin, ethylene-acrylic acid copolymer, epoxy powder, non-toxic polypropylene or non-toxic polyvinyl chloride and other organic substances with a thickness of 0.5-1.0mm on the inner or outer wall of the steel pipe. The composite pipe makes it have the advantages of high strength, easy connection, water impact resistance and so on. [0003] The existing steel pipe outer plastic coat...
