Acid adding funnel for lead-acid storage battery

Abstract

The invention discloses an acid adding funnel for a lead-acid storage battery. The acid adding funnel for the lead-acid storage battery comprises a funnel body, insertion plates, a rubber nozzle, an acid adding opening and supporting frames. Grooves are formed in the inner side of the funnel body. The insertion plates are fixed in the funnel body through the grooves. The bottom of the funnel body is provided with the acid adding opening and the supporting frames. The rubber nozzle is arranged on the acid adding opening. According to the acid adding funnel for the lead-acid storage battery, the insertion plates are arranged in the funnel body so that the situation that the funnel body deforms due to the large size during vacuumization can be avoided; the supporting frames are additionally arranged at the bottom of the funnel body so that the phenomena of deflection, collapse and the like of the funnel body can be avoided, and the effect that the product quality is stable is guaranteed; and the acid adding opening in the bottom of the funnel body and an acid injection nozzle of an upper cover of the storage battery are connected through the rubber nozzle, so that flexible connection is achieved, and the acid injection nozzle is prevented from being damaged.

Description

technical field [0001] The invention belongs to the field of lead-acid batteries, and in particular relates to an acid-adding funnel for lead-acid batteries. Background technique [0002] In order to reduce the pollution to the environment in the production of lead-acid batteries, manufacturers adopt the process of internal formation for production, and the batteries need to be filled with acid before formation. The volume of the traditional acid-feeding funnel is small. In order to ensure the amount of acid, it is necessary to increase the number of times of acid-feeding and vacuuming, which affects the production efficiency; there is no support at the bottom of the funnel, and the funnel is prone to collapse during the battery turnover process, resulting in inaccurate acid volume. , affecting the service life of the battery; the acid inlet at the bottom of the funnel is directly connected to the acid injection nozzle on the upper cover of the battery case, causing a qualit...
