Repairing device for PVC/PVG whole-core flame-retardant conveyer belt

Abstract

The invention discloses a repairing device for a PVC / PVG whole-core flame-retardant conveyer belt. The repairing device of the invention overcomes the problems that conventional repairing devices arenot economic and unfriendly to environment. The repairing device is characterized in that a heating circulation system and a cooling circulation system are arranged; the lower part of a press vulcanizer is provided with a main oil inlet pipe, and the upper part of the press vulcanizer is provided with a main oil outlet pipe; the main oil inlet pipe is connected with branch oil inlet pipes; and themain oil outlet pipe is connected with branch oil outlet pipes. According to the invention, the independent heating and cooling circulation systems are adopted, so the heating and cooling proceduresof the hot plate of the vulcanizer are flexibly transformed; the working temperature of the vulcanization hot plate is accurately controlled; and due to closed circulation of heating and cooling mediums, leakage and venting do not occur, and heat energy loss is low. The device has the advantages of simple structure, convenient conversion, precise control, no pollutant emission, energy conservationand environmental protection, effectively solves problems in repairing processes for the PVC / PVG whole-core flame-retardant conveyer belt, and improves the surface quality of the conveyer belt.

Description

technical field [0001] The invention relates to a whole-core flame-retardant conveyor belt repairing device, more precisely to a hot oil carrier heating and cooling PVC / PVG whole-core flame-retardant conveyor belt, light and thin PVC / PVG conveyor belt repairing device. Background technique [0002] PVC / PVG whole core flame retardant conveyor belt is widely used in coal mines due to its excellent flame retardant, antistatic properties and comprehensive strength properties. However, the production process of the whole core flame-retardant conveyor belt in my country has gradually matured and stabilized after years of development, and most of them use scraping or coating processes to achieve continuous production. During the production process of the whole core flame-retardant conveyor belt, due to various reasons, there will be defects such as exposed cloth on the belt surface, air bubbles, lack of glue, bright scars, and defects, which seriously affect the surface quality of ...

AI Technical Summary

Problems solved by technology

The traditional process uses steam heating, cooling water cooling, continuous heating and cooling process in the production process, although it can also achieve a good repair effect, but it has a large heat loss, waste of water vapor resources, long production cycle, and easy alkali scaling in the equipment Causes disadvantages such as pipeline blockage, which is neither economical nor environmentally friendly, damages equipment, and has a high failure rate and maintenance rate
