The production system and device of the lead powder disclosed by the invention has the advantages that the production efficiency of the high lead powder and the quality of the lead powder are improved, the time is saved, the cost is reduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of lead storage battery production, in particular to a lead powder production system and device. Background technique [0002] Lead powder is one of the most important raw materials for the production of lead-acid batteries. Drum type lead powder machine is the most commonly used machine for producing lead powder from lead block. The drum-type lead powder machine generally includes an outer casing, a self-propelled roller inside the casing, an air supply device, a cooling spray device, etc., in which the roller is used to make the lead particles roll and rub against each other, and the air supply device is used to provide air and Separation of lead powder and lead particles, the cooling spray device is used to cool down the drum. Generally, the drum is installed on the machine base with the hollow shafts at both ends through bearings, and the hollow shafts at both ends are respectively used as the inlet of...

Problems solved by technology

[0010] Many problems often arise during the production of lead powder, for example, the black powder phenomenon, the black powder is the darker color of the lead powder surface, the black powder is mainly caused by the low degree of oxidation of the lead powder during production or the excessive size of the lead particles, which leads to the generation of black powder. The reason is that the temperature in the drum is too low and the negative wind pressure is too large. Measures should be taken to adjust the temperature and negative wind pressure of the drum in time; or because there are too many lead particles in the drum, which also causes black powder; the black powder produced To analyze the particle size of the lead particles, if there are no larger lead particles, it can be placed for a longer period of time, and a small amount can be added to the normal lead powder, and gradually mixed; Add normal lead powder and mix it; if there are a lot of larger lead particles, re-add lead particles at the feeding port of the lead powder machine to make lead powder again, and the amount of lead particles added each time should not be too much

[0011] Another example is the phenomenon of burning powder. Burning powder is the reddish color of lead powder. Burning powder is mainly caused by the high degree of oxidation of lead powder during production. The main reason for the high degree of oxidation is that the temperature in the drum is high and the oxidation is sufficient. Measures should be taken in time to adjust the temperature of the drum; or the lead powder warehouse is prone to excessive oxidation when it is wet, and the temperature will rise due to heat, resulting in powder burning
