In the prior art, adopt the method for atomizing spray that tin plate is cleaned, but the method for atomizing spray can not be accomplished large hitting power to tin plate, this be because its application be the rinse water of the counter-flow vat of next stage, if the increasing hitting power, certainly will will add the flow of giant, so just mean enter reclaim the amount that container for storing liquid reclaims rare plating bath of storing must be very large, rare plating bath of hold tank recovery storage will overflow the groove tank at short notice, make the recovery operation be forced to stop.Use simultaneously the rinse water from the next stage counter-flow vat to enter the method that atomizing nozzle enters into upper level again by pump, can produce a control difficult problem.If three stage countercurrent rinsings just have two pumps, it is very difficult that the flow of these two pumps is consistent, if do not add control, may make a lot of that the water of certain one-level trough reduces, and causes product quality problem.
In order to solve this a pair of contradiction between large flow and the recovery, what the utility model adopted is with the tin plate of rinse water spray in corresponding levels motion at the corresponding levels, make rinse water form a closed circuit self-circulation system, namely realize by the second valve 6 and pump 7, if not having the rinse water overflow of next stage comes, rinse water at the corresponding levels is can not increase or reduce, and so just can simplify a problem as overflowing to the amount that reclaims in the container for storing liquid is exactly the amount that the last step overflow is come.
If a groove is only with a cover spray equipment, general design all is to spray the outlet that is installed in counter-flow vat with cleaning, and the tin plate that is about to leave is cleaned.A feature of the present utility model is the entrance that spray equipment is installed in counter-flow vat, and the tin plate that enters this groove is cleaned.The reason of doing like this is that the utility model is that if also be mounted in outlet, the concentration of plating bath almost equates with the plating bath residual concentration that contains by the tin plate sheet surface after the rinsing at the corresponding levels in the rinse water with rinse water spray at the corresponding levels.But to hang down an order of magnitude the plating bath residual concentration that the concentration of plating bath contains for the tin plate sheet surface that enters entrance at the corresponding levels from upper level in the rinse water.Therefore, spray equipment riding position of the present utility model can make between spray water and the residual plating bath of tin plate sheet surface a concentration difference, can improve cleaning performance like this.
Another one feature of the present utility model is, the in the end outlet of one-level counter-flow vat is equipped with spray equipment, its use be pure pure water, because have the spray of powerful hitting power cleans through first three groups, the residual plating bath of tin plate sheet surface comprises that additive has all dropped to extremely low level, the spray that therefore exports at last, and it is so unimportant that hitting power has seemed, so can spray by the minimum water yield, as long as this water yield is not more than the maximum value that reclaims steam output.Because this water yield is exactly step by step forward overflow and finally enter the amount that reclaims container for storing liquid.
