Coating raw material treatment device for plastic-coated steel pipe

Abstract

The invention discloses a coating raw material treatment device for a plastic-coated steel pipe. The coating raw material treatment device comprises two vertical plates which are correspondingly arranged, wherein a plurality of fan holes are formed in each vertical plate; a fan heater is arranged in each fan hole; a pretreatment device is connected between the two vertical plates in a running fitmanner; the pretreatment device comprises a circular pipe; a group of blanking openings are uniformly formed in the pipe wall of the circular pipe; an arc-shaped plate is slidably connected to the outer wall of the circular pipe; the arc-shaped plate can slide in a reciprocating manner in the axis direction of the circular pipe; a group of avoiding openings are uniformly formed in the arc-shaped plate; and the avoiding openings and the blanking openings can be overlapped or staggered by sliding the arc-shaped plate. The coating raw material treatment device for the plastic-coated steel pipe has the advantages that materials can be dried twice, the drying effect is excellent, the falling amount of the materials can be controlled in the drying process, the materials are conveniently dried bythe fan heaters, and the materials can be effectively prevented from being adhered to the pipe wall of the circular pipe in 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
