Embodiment Construction

[0071] Please check figure 1 and figure 2 A metal strip surface cleaning device with zero discharge of sewage, which includes three brushing units 110, 120, 130, five electrolytic cleaning units 210, 220, 230, 240, 250, a spraying unit 300 and a water circulation system. The metal strip passes through the brush cleaning units 110 , 120 , 130 , the electrolytic cleaning units 210 , 220 , 230 , 240 , 250 and the spray cleaning unit 300 in sequence.

[0072] The metal strip 400 is fed by a plurality of rotating rollers 500 arranged in a staggered up and down manner, and forms a wave-like feeding. Wherein: the brushing units 110, 120, 130, the electrolytic cleaning units 210, 220, 230, 240, 250 and the spraying unit 300 are successively arranged on one side of the adjacent upper and lower turning rollers 500, and the arrangement by this method can reduce the occupancy space.

[0073] The brushing units 110 , 120 , 130 all include a scrubbing shell 610 , a scrubbing mechanism 6...

Abstract

The invention discloses a sewage zero-emission metal strip surface cleaning device. The cleaning device comprises a brushing unit, an electrolytic cleaning unit, a spray unit and a water circulating system, wherein the brushing unit comprises a brushing mechanism, a brushing water supply pool and a brushing water holding pool; the electrolytic cleaning unit comprises an electrolytic mechanism, anelectrolytic water supply pool and an electrolytic water holding pool; the spray unit comprises a spray water supply pool and a spray water holding pool; a metal strip passes through the brushing unit, the electrolytic cleaning unit and the spray unit in sequence; the water circulating system comprises a clear water supply part and a water treatment working section; the clear water supply part isused for providing clear water for the spray water supply pool; the brushing water supply pool is used for receiving the liquid of the spray water holding pool for supplementing an alkaline substance; the water treatment working section recycles the liquid of the brushing water holding pool and is used for treating recycled liquid so as to separate sediments and treated liquid; the electrolytic water supply pool receives the treated liquid of the water treatment working section; and the water treatment working section recycles the liquid of the electrolytic water holding pool.

Description

technical field [0001] The invention relates to a metal strip surface cleaning device and a cleaning method thereof, in particular to a metal strip surface cleaning device capable of realizing zero discharge of sewage and a cleaning method thereof. Background technique [0002] On May 13, 2009, the Chinese patent database disclosed an invention patent application titled "Processing method of continuous hot-dip galvanized steel strip and device used in the method", and its publication number is CN101429638A. It comprises the steps of spraying lye, scrubbing with lye, electrolytic degreasing, scrubbing with water, grinding and cleaning, rinsing with water and galvanizing. Wherein, the cleaning step includes: a step of spraying lye, a step of scrubbing with lye, a step of electrolytic degreasing, a step of scrubbing with clean water, a step of grinding and cleaning and a step of rinsing with clean water. Adopting this method to clean has the following disadvantages: 1. There a...
