Spraying equipment for socket type large-diameter plastic-coated steel pipe

Abstract

The invention discloses spraying equipment for a socket type large-diameter plastic-coated steel pipe, and relates to the field of plastic-coated steel pipes. The spraying equipment comprises a fixed bottom plate, wherein a supporting vertical rod is vertically and downwards welded on the bottom surface of the fixed bottom plate; the top surface of the fixed bottom plate is in bolted connection with a spraying main box, and the top surface of the fixed bottom plate is in bolted connection with a baking main box; a control panel is embedded in one side edge of the baking main box; a dust suction pipe is inserted into the top surface of the spraying main box, and a feeding pipe is inserted into the top surface of the spraying main box; the end, away from the spraying main box, of the top surface of the fixed bottom plate is in bolted connection with an end conveying box, and discharging holes are symmetrically formed in the two side edges of the end conveying box; and sealing rubber blocks are fixedly clamped to the inner side edges of the discharging holes. The equipment is designed to be integrated, the structure is simple, and operation is easy and convenient. Spraying is faster and more efficient by adopting the structure that the inner wall and the outer wall of a pipe body are sprayed at the same time, and meanwhile the machining and production efficiency is greatly improved through the spraying and baking integrated design.

Description

technical field [0001] The invention relates to the technical field of plastic-coated steel pipes, in particular to a spraying equipment for socket-type large-diameter 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] For the current plastic-coated steel pipes, it is necessary ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a spraying equipment for socket-type large-diameter plastic-coated steel pipes, so as to solve the traditional problem in the above-mentioned background technology, which is to spray the outer side first, and transport it to a designated location for drying after the spraying is completed. Dry processing, and then spraying the inner side, makes the operation steps cumbersome and time-consuming, and cannot improve the efficiency of spraying. At the same time, it is time-consuming and laborious to carry back and forth, resulting in a waste of personnel, which is not conducive to the current production. the need for
