Vertical type production line of steel-plastic composite pipe

Abstract

The invention relates to a vertical type production line of steel-plastic composite pipe, comprising a pre-heating device, a plastic dipping device, and a curing-flattening and cooling device, wherein the curing-flattening and cooling device comprises a curing-flattening device and a cooling device; the curing-flattening device is integrally connected with the cooling device. The production line is further provided with a front hoisting device and a back hoisting device, wherein the front hoisting device is arranged in front of the pre-heating device and the back hoisting device is arranged behind the cooling device; the pre-heating device, the curing-flattening device and the cooling device are respectively provided with a conveying device; each conveying device comprises a driving device, a transmission device and a steel pipe hanging device; and the driving device is connected with the steel pipe hanging device through the transmission device. By utilizing a vertical type structure, a steel-plastic composite product with the diameter of 50-1000 mm and the length within 10 m can be produced. According to the production line of the steel-plastic composite pipe provided by the invention, the production efficiency is twice as much as that of horizontal type plastic dipping equipment on the market, the safety coefficient is high, the labor intensity is small and the production labor is 1 / 3 of that of horizontal equipment.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a production line for manufacturing steel-plastic composite pipes. Background technique [0002] The steel pipe coating process is the most advanced anti-corrosion technology in China at present. Coating steel pipes and their series of products, according to the use medium and working conditions, use different formulations of polymer anti-corrosion powder coatings, and apply them evenly on the metal through special equipment. After solidification and plasticization, a uniform, dense and smooth coating is formed on the metal surface, becoming a new type of steel-plastic composite pipe, which combines the excellent mechanical properties of steel and the excellent chemical corrosion resistance of polymer materials. In one, it greatly prolongs the service life of the steel pipe. It has unique anti-corrosion, anti-wear, no fouling, lubricating aid, negative pressure resistance and other advantag...

AI Technical Summary

Problems solved by technology

What this patent adopts is a horizontal structure, and the steel pipe is transported forward through the conveying device. The conveying device includes a frame, a transmission wheel arranged on the frame, a driving motor, and a chain. Turn from laying flat to standing state, and then enter the preheating chamber for preheating, which limits the length of the steel pipe to not be too long, not more than 6 meters, and the production efficiency is low; The heat is not uniform. In the process of dipping, although the polymer material can be evenly distributed on the steel pipe wall, the thickness of the polymer material attached to the steel pipe is uneven due to the uneven heat of the steel pipe.
