Carbon slag cleaning mechanism and method for hanging chain production line

Abstract

The invention discloses a carbon slag cleaning mechanism for a hanging chain production line. A water return pipe (3) communicates with a cross-linking pipeline (1) of the hanging chain production line; a filter valve (5) and a ball valve (6) are arranged on the water return pipe (3); and the ball valve (6) is arranged at the upstream of the filter valve (5). According to the carbon slag cleaningmechanism and method for the hanging chain production line, the time required in the whole process of carbon slag cleaning is greatly shortened, various losses caused by repeated production are greatly reduced, and the quality of a wire core in a starting process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable production, in particular to a carbon residue cleaning mechanism and a carbon residue cleaning method of a catenary production line. Background technique [0002] The insulated cores of high-voltage cables are mainly produced by cross-linking production lines, and the catenary production line is one of the main production lines. [0003] In the production of wire cores, after the copper conductor passes through a three-layer extruder, the surface will be extruded with three layers of plastic, and then enters a long pipe. The upper half of the pipe is filled with nitrogen, and the lower half is cooling water. The cross-linking reaction occurs in the upper part of the high-temperature, high-pressure and sealed nitrogen, and the by-product cross-linked oil is produced. The impurities in the cross-linked oil will be heated and carbonized by the pipeline to form carbon residue. Carbon slag ...

Problems solved by technology

If the charcoal slag is small, if it flows to the rubber seal at the end, it will easily get stuck in the contact between the gasket and the surface of the core, scratch the core, and cause quality problems; or fall into the return pipe from the water-air balance in the middle , if the charcoal residue is too large, it will block the return pipe, causing unstable control of the water level in the pipe, causing the core to vibrate, causing bamboo knots, and causing quality problems. If the charcoal residue is small, it will flow back into the pipe, threatening the seal at the end

[0004] Usually there is a scratch on the surface of the wire core. If the scratch is not deep, stop it and repair it. If the scratch is too deep, you can only stop it immediately. If the water level is unstable due to carbon slag blockage, you can only stop it immediately.

A stoppage of the catenary production line will waste a lot of production materials and energy, and the time required for re-production will take one day at the fastest
