The invention discloses a sealed energy-saving and environmentally friendly pulverizer. The sealed energy-saving and environmentally friendly pulverizer comprises an oxidizing and grinding chamber, wherein a sealing cover is mounted on the top of the oxidizing and grinding chamber; a discharging opening is formed in the bottom of a powder collecting bin; a fixing seat is mounted on the top of the powder collecting bin; liquid oxygen storage tanks are mounted on the fixing seat; a fixing sleeve is mounted on a flow returning tube; an air slowing-down chamber is formed in one end of the powder collecting bin; a negative-pressure fan is mounted on the top of the air slowing-down chamber; a connector is mounted at one end of the negative-pressure fan; a flow returning tube is mounted on the connector; and a control valve is mounted on the flow returning tube. Closed type circulation is adopted, namely a small amount of air is introduced, so that the air circulates in a closed tube; oxygen required for oxidation of lead particles is provided by industrial liquid oxygen; and most of lead powder is still controlled according to the yield of the lead powder and air pressure (maintained at normal pressure) in the closed tube on the basis of the use amount of the liquid oxygen after winnowing.
Description
technical field [0001] The invention relates to the field of pulverizers, in particular to an airtight, energy-saving and environment-friendly pulverizer. Background technique [0002] At present, the lead powder of lead-acid batteries is produced by a special lead powder machine. Because the production of lead powder requires a high-power motor to drive the lead ball to roll and rub, a large amount of heat is generated. A large amount of air is introduced into the mill through a fan to oxidize the small particles of lead. And the small particles of lead powder are sent to the bag filter through winnowing, the small particles of lead powder are collected into the lead powder bin after filtration, the hot air passes through the bag filter, and then passes through the secondary high-efficiency filter to filter out most of the lead powder. After part of the lead powder particles are discharged into the atmosphere through the exhaust pipe, it is inevitable that some tiny particl...
