Description

Crushing and inputting device of potassium chloride for producing electroplating solution {APPARATUS FOR CRUSHING AND SUPPLYING POTASSIUN CHLORIDE}

The present invention relates to an electroplating solution for the electroplating process for the surface treatment of the steel sheet (SRTIP) manufactured in the steel mill, that is, a crushing and dosing apparatus of potassium chloride used to prepare the electrolytic solution. After the input tank is installed on the upper side of the mixing tank used for manufacturing, the input of the potassium chloride used in the preparation of the electroplating solution can be performed more smoothly by putting the cured potassium chloride into the mixing tank while automatically crushing it. The present invention relates to a device for crushing and injecting potassium chloride for producing an electroplating solution.

In general, after the steel sheet is manufactured, the surface of the steel sheet is galvanized or galvanized, such as nickel alloy. The reason for performing the surface treatment of the steel sheet is to make the appearance of the steel sheet and at the same time, the steel sheet product. Its purpose is to surface-treat the steel plate according to the specific use such as corrosion resistance.

In addition, zinc plating (ZnCl2) is 75-85g / l, potassium chloride (Kcl) is 260-290g / l, and 0.4-0.6 ml of nickel chloride (NiCl2) is used for the plating of zinc plating or zinc-nickel alloy. 8-12g / l solution is used, and this plating solution has a standard value, and if it is not met, the insufficient portion should be continuously added.

At this time, the potassium chloride in the material used in the preparation of such a plating solution is in a powdered state unlike the following solutions, so that the potassium chloride is easily inadvertently solidified during long-term storage or transport.

That is, Figure 1 shows a conventional crushing and input operation of the potassium chloride for producing an electroplating solution, as shown in Figure 1, in the prior art potassium chloride inlet 110 installed in the upper portion of the mixing tank 100 for solution preparation. After the opening, the worker manually inputs the potassium chloride 120 loaded on the mixing tank 100. At this time, if the potassium chloride 120 is solidified as described above, the worker manually uses a hammer or the like. By smashing the solidified potassium chloride 120 into the inlet 110 of the mixing tank 100, the operation of adding potassium chloride for the preparation of the plating solution of the steel sheet becomes extremely cumbersome, while the delay is considerably delayed, which eventually delays the plating process of the steel sheet. There is a problem.

In addition, it is difficult to adjust the concentration of the plating solution because the operator manually injects potassium chloride manually, and there is a problem in the safety of the operator because the manual treatment of potassium chloride, which is harmful to the human body, is problematic. The environment is also polluted.

The present invention has been made in order to improve the various conventional problems as described above, the object of which is, after installing the input tank to the upper side of the mixing tank used in the production of the electroplating solution, and automatically crushed the cured potassium chloride introduced therein The present invention provides a crushing and feeding device of potassium chloride for preparing an electroplating solution, which is capable of carrying out the addition of potassium chloride used in the preparation of an electroplating solution by allowing the mixing tank to be added.

In addition, another object of the present invention is to add the coagulated potassium chloride into the input tank, and then it can be put in a predetermined amount in the mixing tank for crushing and plating solution production to prevent the scattering of dust generated during the crushing of potassium chloride to prevent contamination of the working environment. It is easy to adjust the concentration of the plating solution, and it is easy to adjust the concentration of the potassium chloride, and the fully crushed potassium chloride is added to provide a uniform concentration of the plating solution so that the plating process of the steel plate can be precisely performed. To provide a shredding and feeding device.
