Vacuum acid injecting tunnel of storage battery

Abstract

The invention relates to a vacuum acid injecting tunnel of a storage battery. The tunnel comprises a cup body, a cup cover and a liquid injection port. The lower end of the cup body is provided with the liquid injection port, and the liquid injection port and the cup body are combined into an integral structure; the cup cover and the cup body are connected in a detachable and flexible connection mode, the cup cover is provided with a liquid inlet and a vacuum connector, and the cup body is at least provided with a visible structure, wherein a part of the structure is made of a transparent material; from the visible structure, liquid in an inner chamber of the cup body can be seen from the outside part of the cup body, the cup body is made of transparent plastic, and the external surface of the cup body is provided with a reinforcing rib. Compared with the prior art, the cup body is provided with the visible structure which is prepared by the transparent material, and liquid in the cup body can be seen from the outside of the cup body through the visible structure; the product is convenient for operation and usage cost is low. The cup cover is provided with the vacuum-pumping connector, so liquid injection is smooth, and operation is convenient. The vacuum acid injecting tunnel is suitable for various storage batteries of different capacities, and the vacuum acid injecting tunnel has good versatility.

Description

technical field [0001] The invention relates to a storage battery electrolyte injection device, in particular to a vacuum acid injection funnel for lead-acid storage batteries. Background technique [0002] At present, the existing lead-acid battery manufacturing industry usually requires quantitative injection of the product. After the battery is assembled into a semi-finished product, a certain amount of electrolyte is injected into the semi-finished battery quantitatively. After the electrolyte is injected, the battery is charged and discharged many times. , and chemically react with the substances in the battery, so that the battery has a certain charge and discharge capacity. During the operation, the electrolyte must be added quantitatively through the container. If the electrolyte is too little or too much, the normal chemical reaction cannot be guaranteed, or the performance of the battery will be affected. The existing quantitative injection containers for lead-aci...

Problems solved by technology

During the operation, the electrolyte must be added quantitatively through the container. If the electrolyte is too little or too much, the normal chemical reaction cannot be guaranteed, or the performance of the battery will be affected.

The existing quantitative injection containers for lead-acid batteries are generally made of opaque acid-resistant materials, and the change of the liquid level cannot be seen during use. Usually, it is necessary to set up quantitative injection equipment, which is costly, and during the injection process Bubbles will be generated, resulting in poor liquid injection, reducing production efficiency and inconvenient operation
