Device and method for detecting residual chlorine in water for heat treatment of tire bead wire

Abstract

A residual chlorine detection device for tire bead wire heat treatment water comprises a tank, a heating wire is wound on the periphery of the tank, a drain hole and a water inlet are formed in the tank, a valve is arranged at the drain hole, a residual chlorine probe is fixedly installed in an exhaust hole, and an upper box and a lower box are arranged in the tank in a sliding mode. And the periphery of the upper box body and the periphery of the lower box body are respectively in airtight sliding contact fit with the inner periphery of the tank body. The device is simple in structure and ingenious in conception, scales on the side wall of the tank body are scraped and the inner wall of the tank body is cleaned through the upper box body and the lower box body which continuously move up and down, and in the up-down moving process of the upper box body, the space between the upper box body and the lower box body can be increased, so that negative pressure is formed, tap water can be boiled conveniently, residual chlorine in the tap water can overflow conveniently, and the service life of the tank body is prolonged. And meanwhile, the scraped scaling slag can be collected between the upper box body and the lower box body, the market requirement can be met, and the device is suitable for popularization.

Description

technical field [0001] The invention belongs to the field of residual chlorine elimination devices, in particular to a residual chlorine detection device and method for bead steel wire heat treatment water. Background technique [0002] In the production process of steel wire hardening, water treatment is widely used as a cooling and flushing process, but it is well known that chloride ions in water are harmful to oil tempered steel wires. Tap water is generally used in water treatment, but tap water contains more Chloride ions usually need to be heated to quickly remove chloride ions in tap water, but during the heating process of tap water, it is easy to scale, which affects subsequent heating, and when a large amount of tap water is heated, it is not conducive to the overflow of chloride ions in tap water, which cannot be satisfied. Therefore, we invented a residual chlorine detection device and method for bead steel wire heat treatment water. SUMMARY OF THE INVENTION ...
