A method and a device for acid circulation pole plate formation

Abstract

A method and a device for acid circulation pole plate formation are disclosed. The method comprises the following steps: a high-level acid-storing tank, a flow control valve, a temperature control heater, an acid inlet pipe, an acid-gathering tank, an acid outlet pipe, a low-level acid-storing tank, an acid pump, and an acid return pipe are provided outside a formation tank to constitute an acid circulation pole plate formation device; an acid flow of acid liquor in the high-level acid-storing tank is regulated in a range of 50 to 100 ML / S via a flow control valve through the flow control valve; the acid is heated to 20 to 40 DEG C via a temperature controller and flows automatically into the formation tank; then after the formation tank is fulfilled with the acid, the acid overflows into the acid-storing tank through an overflow hole and then into the low low-level acid-storing tank via the acid outlet pipe; finally the acid is returned to the high-level acid-storing tank for acid storage via the acid pump and the acid return pipe, concluding acid circulation and acid temperature control. The method changes a static state of acid in a formation tank of the prior art, gets rid of polarization effect of the formation process, improves formation efficiency, saves formation time and electric quantity consumed for formation, and directly leads to reduction of area and space taken by the pole plate formation process.

Description

technical field [0001] The invention relates to an external formation process and equipment for battery pole plates, in particular to an acid cycle pole plate formation method and equipment, belonging to the field of battery production. Background technique [0002] The most time-consuming production process in the production process of batteries is the plate formation process, which generally requires 48 hours and a large amount of electric energy. The Chinese invention patent application with the publication number CN1391295 provides a "Plate Formation Process for Lead-acid Battery", including the preparation of the pole plate, the production of the plate group, and the preparation of the electrolyte. The plate group is placed in the electrolyte , and then carry out the plate charging operation, which is characterized in that the charging operation is controlled as positive charging for a period of time, then the reverse charging operation is inserted, and then the positiv...

Problems solved by technology

However, the above-mentioned technical scheme is the same as the prior art. During the formation process, the pole plate is invaded in the formation tank containing static acid liquid, which causes uneven stratification of acid concentration and temperature in the formation tank during the formation process of the pole plate. It takes a long time and consumes a lot of electricity, occupying a huge production space
