Lead-acid storage battery polar plate dewatering device

Abstract

The invention discloses a lead-acid storage battery polar plate dewatering device, which belongs to the technical field of storage battery preparation. The lead-acid storage battery polar plate dewatering device comprises a conveyor belt used for conveying a polar plate, wherein a plate pressing belt which is provided with a hole and can circularly move is arranged above the conveyor belt; the plate pressing belt is provided with a water adsorption section which simultaneously advances to the same direction along with the conveyor belt; when the polar plate is conveyed, a water adsorption section of the plate pressing belt and the conveyor belt are respectively abutted against two surfaces of the polar plate; a water adsorption cover which is tightly against the plate pressing belt and isconnected with a vacuum suction device through a pipeline is arranged above the water adsorption section; the plate pressing belt is divided into the water adsorption section and a dewatering section;under the function of a driving roller, the plate pressing belt is circularly driven, the water adsorption cover adsorbs parts of water in the polar plate to the plate pressing belt in a polar plateconveying process, the water is removed in the dewatering section along with the transmission of the plate pressing belt, a purpose of the partial dewatering of the polar plate is realized, and the drying temperature of a dryer of a next working procedure is effectively lowered.

Description

technical field [0001] The invention relates to the technical field of battery preparation, in particular to a lead-acid battery plate dehydration device. Background technique [0002] In the production process of the lead-acid battery plate, it is necessary to roll the plate after coating, which can increase the amount of lead paste water on the plate, improve the strength of the lead paste on the surface of the plate, lower the content of lead sulfate on the surface of the plate, and inhibit the discharge of the battery In the process, lead sulfate is generated, and the conductivity of the lead paste on the surface of the plate is improved, thereby improving the overall performance of the battery. [0003] The patent literature with the application publication number of CN 105470472A discloses a method for acid leaching of lead-acid battery pole plates. The process is as follows: the coated lead-acid battery pole plates are placed on the conveyor belt, and the acid leachin...

AI Technical Summary

Problems solved by technology

[0005] 1. The production environment is poor, sulfuric acid drips from the production site, pollutes the site environment, increases the load of the sewage station, and increases the cost of environmental treatment;

[0006] 2. Increase the cost of sulfuric acid for leaching acid;

[0007] 3. The lead sulfate content in the lead plaster washed out during acid washing is too high to be recycled;

[0008] 4. Dilute sulfuric acid for leaching acid requires equipment configuration and manual inspection, which increases kinetic energy consumption and labor costs;

[0009] 5. Fluctuations in the specific gravity of leached acid will cause fluctuations in the quality of the green plates

[0010] In the prior art, storage battery manufacturers improve the production process and cancel the acid leaching process. Studies have shown that the elimination of leaching acid has no adverse effects on product performance
