A vacuum feeding device for lead-acid battery and paste

Abstract

The invention relates to a vacuum feeding device used for paste-mixing of lead-acid battery. The vacuum feeding device comprises a paste-mixing machine and a mixing barrel connected with the paste-mixing machine; the paste-mixing machine is connected with the mixing barrel through a material-discharging pipe; one side of the mixing barrel is connected with a raw material barrel through a feeding pipe; the other side of the mixing barrel is provided with a vacuum machine inserting into the mixing barrel; a magnetic filter bar for filtering impurities is disposed at a connecting part of the material-discharging pipe and the mixing barrel; a vibration rod capable of accelerating blanking speed is disposed in the mixing barrel in an insert manner; the feeding pipe is provided with a feeding valve; and the material-discharging pipe is provided with a material-discharging valve. A totally enclosed vacuum feeding manner is adopted in a feeding process of the vacuum feeding device. The feeding process has no pollution and can realize automatic resorption of the raw materials. By arranging the magnetic filter bar in the mixing barrel, a number of impurities in the raw materials can be filtered out; and purity of the raw materials can be increased. A vibrator is disposed in the mixing barrel, so that the blanking speed can be accelerated; and valves are disposed on both the material-discharging pipe and the feeding pipe, so that the valves can be closed when the material is fed completely.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to a vacuum feeding device, in particular to a vacuum feeding device for lead-acid batteries and paste. Background technique [0002] At present, the production process of lead-acid batteries includes the steps of making lead powder, pouring and repairing the plates, mixing paste, point solution, and drying. Among them, neutralizing paste is one of the most critical steps in the entire battery manufacturing process, which directly affects the quality of the battery. And the service life, the feeding process of the cream is usually manually added, and the material is directly poured into the mixing tank, the dust is relatively large, it is easy to be poisoned when inhaled into the human body, and it will harm people's health. The bottom end is relatively wet, and it is easy to stick some auxiliary materials on the inner wall, and yes, the auxiliary materials are not evenly stirred....
