Steel wire rust cleaning device

Abstract

The present invention relates to a steel wire rust-removing method and its equipment. Said method mainly includes the following two steps: firstly, mechanically-loosening rusty steel wire by utilizing a group of stripping rollers to make the rust on the steel wire surface be loosened; then brushing the rusty steel wire surface by adopting a steel wire rust-removing device. Said steel wire rust-removing equipment includes the following several portions: a supporting frame, a hollow main shaft, a rotary disk, a rust-removing roller, a pair of front guide sleeves and a pair of rear guide sleevesand a group of stripping rollers.

Description

Steel wire derusting device technical field The invention relates to a method and device for removing rust on the surface of a mechanical steel wire material before cold drawing and stretching. Background technique The traditional derusting of steel wire is realized by the chemical reaction of hydrochloric acid. The specific process is firstly heated with hydrochloric acid, put into the steel wire material to etch, and then rinse and neutralize. During the neutralization process, the hydrochloric acid and the neutralization liquid need to be heated, and they need to be washed in between, which consumes a lot of energy such as fuel and water. At the same time, using this chemical method to treat steel wire will produce a large amount of waste acid, which has strong corrosion Untreated discharge will seriously pollute the water body, soil and air, so the discharge is strictly restricted by the state, and it needs to be treated before it can be discharged. However, the cost o...

During the neutralization process, the hydrochloric acid and the neutralization liquid need to be heated, and they need to be washed in between, which consumes a lot of energy such as fuel and water. At the same time, using this chemical method to treat steel wire will produce a large amount of waste acid, which has strong corrosion Untreated discharge will seriously pollute the water body, soil and air, so the discharge is strictly restricted by the state, and it needs to be treated before it can be discharged. However, the cost of waste acid treatment is extremely high, so there is a phenomenon of incomplete treatment and discharge, causing environmental pollution. Not conducive to environmental protection
