Coating raw material processing device for plastic-coated steel pipe

Abstract

The invention discloses a paint raw material processing device for plastic-coated steel pipes, which comprises two corresponding vertical plates, each vertical plate is provided with a plurality of fan holes, each fan hole is equipped with a heater, two The two vertical plates are rotated and connected to the pretreatment device. The pretreatment device includes a round tube. A group of blanking openings are uniformly arranged on the tube wall of the round tube, and an arc-shaped plate is slidably connected to the outer wall of the round tube. The arc-shaped plate can move along the circle. The axial direction of the tube slides back and forth, and a group of relief openings are evenly arranged on the arc-shaped plate. By sliding the arc-shaped plate, the relief opening and the blanking opening can be overlapped or dislocated. The advantages of the present invention: the coating raw material processing device for plastic-coated steel pipes provided by the present invention can dry the materials twice, the drying effect is good, and the amount of material falling can be controlled during the drying process, which is convenient for the heater Drying can also effectively prevent the material from sticking to the tube wall during the pre-drying process.

Description

technical field [0001] The invention relates to the technical field of production equipment for plastic-coated steel pipes, in particular to a coating raw material processing device for plastic-coated steel pipes. Background technique [0002] Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, use steel pipes as the substrate, and weld a layer of plastic anti-corrosion layer or Steel-plastic composite steel pipe with plastic anti-corrosion layer welded on the inner and outer surfaces. Plastic-coated steel pipe has excellent corrosion resistance and relatively small frictional resistance. Epoxy resin coated steel pipe is suitable for the transportation of water supply and drainage, sea water, warm water, oil, gas and other media, and PVC coated steel pipe is suitable for the transportation of drainage, sea water, oil, gas and other media. [0003] The quality and performance of plastic-coa...

AI Technical Summary

Problems solved by technology

The plastic-coated steel pipe raw material processing device in the prior art is to directly place the raw material in the oven for drying, and then take it out for use, but this type of oven generally adopts continuous high-temperature drying, which will have a certain impact on the performance of the plastic powder
