Description

Technical Field

[0001] This utility model relates to the field of battery plate drying technology, specifically a lead-acid battery plate drying device. Background Technology

[0002] Lead-acid batteries are a type of storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. The plates are the core components of the battery. The plates of a lead-acid battery consist of a base electrode and active material, and are the core components for storing electrical energy. In the production process of lead-acid batteries, drying the plates is one of the key processes. The drying quality directly affects the electrochemical performance, mechanical strength and service life of the plates.

[0003] Chinese Patent Publication No. CN218722666U, authorized on March 24, 2023, discloses a plate drying device for lead-acid battery production. The device includes a mounting frame, a transmission assembly, and a limiting frame. The transmission assembly is rotatably connected to the mounting frame, and consists of two electric pulleys and two flat belts. Electric pulleys are rotatably connected to both sides of the mounting frame, and two flat belts are wound around the two electric pulleys. A limiting frame is symmetrically connected to the left side of the mounting frame, positioned above the transmission assembly. Gas is blown out by a cylinder to agitate water stains on the surface of the plates. The plates are then dried by the action of a drying chamber, achieving rapid and uniform drying of the plates.

[0004] Existing drying devices mostly use a one-way hot air direct blowing method, which results in uneven heating on both sides of the electrode plate. This can easily lead to localized over-drying and cracking or localized under-drying. Before drying, dust and impurities adhering to the electrode plate surface solidify on the electrode plate surface during the drying process, reducing battery performance and failing to meet usage requirements. Utility Model Content
