SU16120A1 - Meidinger type galvanic cell - Google Patents

Description

The proposed invention relates to a already known galvanic cell of the Meidin-type type with an inner vessel containing an electrolysis reserve and a device regulating the level of electrolyte in an outer vessel in which electrodes are located one above the other. The invention consists in that a lifting stopper is used to open and close the inlet opening arranged in the bottom of the inner vessel, and the body placed in the inner vessel is intended to change the level of electro in it; lit. /

In FIG. 1 depicts a vertical section of a galvanic cell; FIG. 2- its horizontal section; FIG. 3 is a section of a modification of the body, nome1, a small inner vessel, and FIG. 4-section of the modified element.

The element (Fig. I and 2) - consists of two vessels: external A and internal nodvizhny B. Internal has a hole in the bottom, narrowed in its lower part and closed with a stopper (7 (Fig. 1). Inside the vessel B there is a massive cylindrical body D, which can be raised and lowered. Two outer tube electrodes are placed in the outer vessel: copper Cn and zinc Z ,,, connected to the terminals fixed on the lid of the E. - element. It passes through a hole in body D and can be fastened with a screw N to the lid of vessel B.

Before filling the element with solutions; the lower opening of the inner vessel is fixed with stopper C, body J) rises to a high level, after which a solution of sulfuric acid is poured into the outer vessel, and into the inner vessel is a solution of copper vitriol. The latter solution is infused slightly below the M level, since its density is greater than the density of the sulfuric acid solution. As long as the solutions are disconnected, the element cannot give a current. To put it into action, the body should be lowered.) At the bottom of the inner vessel B, thanks to which the level of the copper solution rises above level G, and then open the lower opening. Since the lumen of the lower opening of the inner vessel is small, the solution of copper sulphate will begin to overflow into the outer vessel slowly and without mixing with the sulfuric acid solution, cutting will be arranged, delimited by a layer in the lower part of the outer vessel, covering the copper electrode. and a solution of sulfuric acid, podnn11 above ;; urodn, will cover the copy electrode If 1 now connect the terminals with a conductor, the element will give an electric current. When the need for current passes, body D rises, the difference in levels is again obtained, and the solution of copper sulfate slowly flows into the inner vessel. Thereafter, the lower opening is sealed with a plug, which will act as an obstacle to the necking of the solutions. When the solution of the honeydew is worked out, the body D, at the closed lower opening, is lowered, the solution is forced out into the upper part of the vessel, taken with a pipette or other method and replaced fresh.

The massive cylindrical body D, displacing the solution of copper sulfate, occupies a significant place in the element. It can be replaced with a hollow annular vessel (Fig. 3) of the same size with a hole closed with plug C, and filled with crystals of copper sulphate and water. After lowering it during charging, both the holes and the gap open up before passing into the outer vessel, pass through the copper sulphate and thus will be saturated. When dKing, first lock the opening of the moving vessel and then lift it up.

It is possible to modify the element in which a siph jR (Fig. 4) is used in an annular vessel D instead of a hole closed by a stopper, equipped with an opening F in the upper knee. Part of the liquid passes as; It is indicated: by arrows, through vessel D with copper: vitriol and siphon R. When discharging, when MOBILE, the vessel will be lifted, liquid,: - it was in it, you could be. the same siphon. To prevent this from happening,;. Bending the siphon, in the upper part, is done

small hole jF. As long as this hole is inside the LIQUID, the siphon will work almost normally, i.e., visibility, passing through. it will be fed through the lower wide opening of the siphon, and only undetected, the amount of solution will pass through the upper opening. When, as it is raised, the bend of the siphon decreases, out of the liquid, its work will stop as a result of air passing into it.

  I Subject of the patent.

 , i

1. A galvanic cell of the Meidil-Tfpa type with an internal vessel; containing, an electrical stock of electrical equipment and a device regulating the electrolyte level in the vessel bridge, in which other electrodes are located above the other, characterized by lifting, stopper C serving — for opening and closing the outlet of the hole in the bottom of the inner vessel L, in which The body Z is placed; it is assigned to raise the electrolysis level of the inner vessel when raising and lowering it (Fig. 1 and 2). ;; ,

2. Eid inoculation described in c. 1 electroplating element, characterized in that the body D is made in the form of a hollow annular vessel, provided with an opening, closing 1 (with a lifting plug C and serving as a core for copper sulphate (Fig: 3).

3. Od / modified alteration. In item 2 of the galvanic element is the same because, in order to keep the solution of the copper KyHOpoc i solution in the annular vessel while lifting, the siphon jR provided in the upper knee with a hole F (Fig. 4) was used instead of the stopper. , .. / - / to the patent A.
