Intelligent epoxy powder anti-corrosion spiral steel pipe production equipment

Abstract

The invention discloses intelligent epoxy powder anti-corrosion spiral steel pipe production equipment which comprises a track, pipe rotating trolleys, an inner recycling assembly, a medium-frequency support, an upper powder spraying chamber, a powder spraying cooling box, a lower recycling chamber and a gun barrel support. The two pipe rotating trolleys are relatively movably installed on the track, the pipe rotating trolleys drive the inner recycling assembly to synchronously move on the track, the intermediate-frequency support, an outer powder spraying chamber and the gun barrel support are sequentially and fixedly arranged above the track, an inner powder spraying cooling box is installed on the upper powder spraying chamber and connected with the gun barrel support through a cantilever, and the pipe rotating trolleys can sequentially penetrate through the intermediate-frequency support and the outer powder spraying chamber back and forth till the pipe rotating trolleys are close to the gun barrel support. According to the intelligent epoxy powder anti-corrosion spiral steel pipe production equipment, modularized installation is used as a whole, a module can be directly replaced when working parts are replaced, the working efficiency is high, and a pipeline is heated in a balanced mode in the powder spraying process and has no color difference.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion equipment for steel pipes, in particular to an intelligent epoxy powder anti-corrosion spiral steel pipe production equipment. Background technique [0002] Steel pipe is an important element used to transport fluids, powdery solids, and exchange heat energy, and plays an important role in hydraulic engineering, oil and natural gas transportation. The steel pipe is easy to form a rust layer on its surface during placement, so it is necessary to spray a layer of protective coating on the surface of the steel pipe. The inner surface of the steel pipe is in direct contact with the material, so the treatment of the inner surface of the steel pipe is very important. [0003] Existing epoxy powder coating technology includes external epoxy powder coating and internal epoxy powder coating; in terms of process, it can be divided into electrostatic spraying, thermal adsorption, shower coating and d...

AI Technical Summary

Problems solved by technology

The existing technology mostly adopts the spraying method of "inside first, then outside" or "outside first, then inside". Feasible; but this will cause the disadvantages of repeated equipment configuration, large energy consumption and low production efficiency; and the secondary heating process will cause certain structural damage to the existing coating

[0004] In the prior art, the general equipment of the whole epoxy powder spraying technology is a combination of multiple parts in bulk, and the assembly is relatively cumbersome; it is also difficult to recycle the scattered powder in the whole process of powder spraying, and there is no need for the powder produced in the work. Recycling and reuse will cause waste of resources and make the working environment worse. Staff inhaling excess dust or powder may easily cause health problems, which is not in line with the concept of environmental protection
