Steel strip oil-removing rust-removing apparatus and method

Abstract

The invention provides a steel strip oil-removal and rust-removal device and a steel strip oil-removal and rust-removal method. The device comprises an enclosed soundproof engine body, and a sand feeding system and a sand grinding system which are arranged in the engine body; the engine body wall is provided with an equipment installation operation door, a vertical steel strip inlet trough and a vertical steel strip outlet trough; the sand grinding system comprises a grinding head mechanism and an installation base; the grinding head mechanism comprises a motor, a steel wire wheel and a couple; the motor is connected with the installation base; the steel wire wheel is respectively tangent to or locally attached to two sides of the steel strip; the sand feeding system comprises a sand hopper, a sand pipe and a sand feeding machine; the sand outlet of the sand pipe is arranged above the steel wire wheel and leads the sand flow to flow through the screw-in contact inlet of the steel wire wheel and the steel strip at least; the method comprises the steps as follows: sand loading, steel strip piercing, adjusting the sand grinding system to lead the steel wire wheel to be tangent to or partly attached to the steel strip, starting the sand feeding machine for sand feeding, starting the sand grinding system to remove the oil and rust, and continuously conveying the steel strips, etc. The device and method of the invention can realize dual types of oil-removal and rust-removal: friction type and impact type, have high efficiency, low noise, no pollution, and comply with the continuous oil-removal and rust-removal disposal to the steel strips.

Description

technical field [0001] The present invention relates to a device for degreasing and derusting at the same time, and also relates to a method for degreasing and derusting using this device, more specifically, relates to a steel strip degreasing and derusting device and a steel strip degreasing and derusting device method. Background technique [0002] In the process of mechanical production and processing, it is often necessary to degrease and derust raw materials or parts. Existing degreasing and rust removal technologies can be divided into two categories: physical methods and chemical methods, and each method can be used alone or in combination in application. [0003] The chemical degreasing method is mainly to saponify or emulsify the oil through chemical reaction, and then wash it off. The chemical derusting method uses the chemical reaction between acid and rust to convert the rust into soluble substances to achieve the purpose of removing rust. [0004] The chemical...
