Abstract

The invention relates to a large polar plate production process, which comprises the following steps of: S1, carrying out continuous copper removal on crude lead liquid to obtain impurity-removed lead liquid; S2, further conducting copper removal on the impurity-removed lead liquid obtained in the step S1, so that copper-removed lead liquid meeting a standard is obtained; and S3, starting a casting device to cast the copper-removed lead liquid obtained in the step S2 under the constant temperature condition by a control unit, and acquiring a large polar plate after cooling and demolding, wherein the control unit adjusts an opening degree of an electromagnetic valve according to a comparison result of an actual bubble production speed and a preset bubble generation speed, and when the opening degree of the electromagnetic valve needs to be adjusted, the control unit calculates a bubble generation speed difference value so as to select a corresponding adjusting coefficient to adjust the opening degree of the electromagnetic valve. According to the large polar plate production process, the generation of foamed lead can be effectively reduced, so that the quality of the anode plate is improved, the vertical mold pouring speed is further effectively improved, the working efficiency is improved, and the labor intensity of personnel is reduced.

Description

technical field [0001] The invention relates to the technical field of large pole plate production, in particular to a large pole plate production process. Background technique [0002] After the electrolysis of the large plate was put into production, about 3-5 cm of foamy solid lead appeared at the bottom of the anode plate during the pouring process of the positive plate vertical mold. In the electrolyte, after being bonded to the cathode, lead ions are discharged and precipitated on it, causing a large number of electrical short circuits, reducing the yield and quality of precipitated lead, and the current efficiency is about 88%. Ag, Cu, and Bi exceed the standard, which seriously restricts production. Contents of the invention [0003] Therefore, the present invention provides a large plate production process to overcome the problem of low production efficiency of the large plate caused by foamy solid lead at the bottom of the anode plate in the prior art. [0004] ...
