Problems solved by technology

At present, the electrolyte is absorbed by normal pressure in the battery storage tray, which may easily cause insufficient electrolyte retention in the battery, the air in the positive electrode ring is not easy to discharge, and the absorption time is long. The alkaline electrolyte is exposed to The longer the time in the air, the easier it is to cause carbonation of the electrolyte and evaporation of water, all of which will lead to the increase of the internal resistance of the battery, the deterioration of the large-load discharge characteristics and the poorer performance after storage.

Embodiment Construction

[0016] Embodiments of the present invention will be specifically described below in conjunction with the above-mentioned drawings.

[0017] Such as figure 1 As shown in ~4, the vacuum absorption device for alkaline dry battery electrolyte is a technical solution for how to quickly absorb the electrolyte into the positive electrode ring and separator paper of the battery 41 injected with electrolyte by means of vacuum absorption. This scheme forms the support of the whole device with the base 22, four columns 10, and the top plate 9 at the top of the columns fixed to each other. Base and top plate are provided with vertically installed main shaft 19, the main shaft bottom is supported in the bearing in the bearing seat 21 fixed with the base, the top extends upwards through the top plate, and the main shaft is input rotational power through gear 23 by frequency conversion motor.

[0018] The main shaft between the top plate and the chassis is provided with a cup rotating mecha...

Abstract

The disclosed vacuum absorption device for electrolyte in alkali dry cell comprises: a base, a column, a top plate, a main shaft set on the base and plate to drive the rotation by frequency- changing motor and gear, multilayer synchronous rotating support-cup rotative mechanisms every with multiple support-cup positions for assembling cell roundly and transferring the cups, a cell set in the room sealed by the cover cup and support cup, a gas-pipe member connected with a vacuum pump and controlled by a vacuum valve. this invention is smart and simple, fit to fast complete the absorption process, avoids liquid splashing, and overcomes defects in prior art.

Description

technical field [0001] The invention relates to a battery vacuum absorbing device, in particular to an alkaline dry battery electrolyte vacuum absorbing device. Background technique [0002] With the development of modern electrical appliances and the gradual popularization of digital products, the high-current and high-power electrical products powered by dry batteries are gradually increasing, and the requirements for battery performance are also getting higher and higher. The outstanding performance is to maintain excellent and durable products under heavy load. performance. After research, the performance of alkaline dry batteries decreases after discharge or battery storage under heavy load. The biggest reason is that the electrolyte in the battery is reduced or dried up. Therefore, how to increase the content of electrolyte in the battery has always been a problem for battery manufacturers. One of the difficulties that need to be solved. At present, the electrolyte i...
