Centrifugal rotating E-shaped carbon steel piece lining plastic device provided with heat preservation cover

Abstract

The invention relates to a centrifugal rotating E-shaped carbon steel piece lining plastic device provided with a heat preservation cover, and belongs to the technical field of workpiece processing. The device is provided with a supporting device, a driving device, a heating device, a vibrating device and a heat preservation device to plastic-line an E-shaped carbon steel piece so as to increase the corrosion resistance, insulation performance and the like of the E-shaped carbon steel piece. The supporting device is arranged at the bottom of the E-shaped carbon steel piece to support the E-shaped carbon steel piece; the driving device is arranged at one side of the E-shaped carbon steel piece to drive the E-shaped carbon steel piece to rotate centrifugally; the heating device is arranged near the outer side wall of the E-shaped carbon steel piece to heat the E-shaped carbon steel piece so as to melt polyethylene powder adhered and sprayed on the inner wall of the E-shaped carbon steelpiece to plastic-line the E-shaped carbon steel piece; the vibrating device is arranged at the bottom of the supporting device to vibrate the E-shaped carbon steel piece during the rotation of the E-shaped carbon steel piece to adhere polytetrafluoroethylene powder on the inner wall of the E-shaped carbon steel piece more firmly; and the heat preservation device is used for heat preservation of the E-shaped carbon steel piece so as to improve the plastic-lining efficiency.

Description

technical field [0001] The invention belongs to the technical field of workpiece processing, and in particular relates to a centrifugally rotating E-shaped carbon steel piece lining plastic device provided with a heat preservation cover. Background technique [0002] Steel-lined plastic pipe fittings are one of the commonly used pipe fittings in the domestic chemical industry. The outer wall is made of carbon steel, and the inner lining is made of PE and PO materials. PE and PO materials have many characteristics of corrosion resistance, low temperature resistance and electrical insulation, so they are used as metal pipe fittings. Best choice for lined plastic. Steel-lined plastic pipe fittings have excellent temperature resistance and corrosion resistance, and are ideal transportation equipment for strong corrosive media. Steel-lined plastic pipe fittings that can operate stably under high-temperature extreme negative pressure conditions for a long time solve the shortcomi...

AI Technical Summary

Problems solved by technology

[0003] The currently used plastic lining device is to fix the processed plastic pipe on the inner side of the E-shaped carbon steel part under the condition of heating and softening. This has the problem that the plastic pipe is not tightly attached to the inner wall of the E-shaped carbon steel part. Poor plastic effect
