Lead powder recovery equipment

Abstract

The invention discloses lead powder recovery equipment. The lead powder recovery equipment is used for removing iron impurity in lead powder recycled by an environmental-friendly dust remover effectively, so that iron impurity quality of the recycled lead powder is consistent with standards. The lead powder recovery equipment comprises an iron impurity primary filtration device and an iron impurity refined filtration device; the iron impurity primary filtration device comprises a belt transmission mechanism and a lead powder feeding device; one of the two belt wheels of the belt transmission mechanism is a magnetic belt wheel; the iron impurity refined filtration device comprises a dust raising type fine filter, a pulverizer, and a vibrating screen; the lead powder feeding device is extended along a feeding direction of the belt transmission mechanism, one end of the lead powder feeding device is extended right below the magnetic belt wheel, and the other end is extended toward a direction far from the belt transmission mechanism, and is arranged above a feed inlet of the pulverizer; the dust raising type fine filter comprises a sealed dust raising chamber and a plurality of magnetic rolls which are arranged in the sealed dust raising chamber from the upper part to the lower part successively; the top surface of the dust raising chamber is provided with a feed inlet, and the bottom surface of the dust raising chamber is provided with a feed outlet.

Description

technical field

[0001] The invention relates to a recycling device, in particular to a lead powder recycling device which can effectively remove iron impurities in the lead powder. Background technique

[0002] At present, lead-acid battery manufacturers usually treat the lead powder recovered by the environmental dust collector as scrap lead powder, which not only wastes resources, but also easily pollutes the environment. In order to avoid waste of resources, some manufacturers currently add the lead powder collected by the environmental protection dust collector directly to the lead powder used for compounding paste in proportion, but the defect of this is: because there will be iron impurities in the lead powder collected by the environmental protection dust collector, Iron impurities are mixed into the lead paste; and iron impurities will cause excessive self-discharge of the battery, which will not be durable for storage, and will aggravate the water loss of the batter...

Embodiment 1

[0039] Embodiment 1: as figure 1 As shown, a lead powder recovery equipment includes a primary filter device 2 for iron impurities and a fine filter device 3 for iron impurities. The primary filter device for iron impurities includes a first screw elevator 1, a first sealed chamber 21, a belt transmission mechanism 22 for conveying lead powder and a lead powder feeder 24 located below the belt transmission mechanism. The belt transmission mechanism is arranged in the first sealed chamber. The belt transmission mechanism comprises two pulleys and a conveyor belt tensioned on the two pulleys. There is a pulley in the two pulleys in the belt transmission mechanism to be the magnetic pulley 23. Magnetic pulley refers to a pulley with magnetism. In the first sealed chamber, an iron impurity recovery frame 25 with an upper end opening is located below the belt transmission mechanism. The iron impurity recovery frame is located between the two pulleys, and the iron impurity recov...

Embodiment 2

[0054] Embodiment 2, the remaining structure of this embodiment is with reference to embodiment 1, and its difference is:

[0055] Such as Figure 4 , Figure 5 As shown, the side walls of the dust raising chamber 3 a are composed of an outer wall 341 and an inner wall 342 . The inner and outer walls are parallel to each other, and there is a gap between the inner and outer walls. On the inner side wall, the positions opposite to the two ends of each magnetic force roller are respectively provided with roller passing holes. The through hole of the roller is a round hole. Spacer sleeves 9 are respectively provided at the through holes of the rollers between the inner and outer walls. The spacer sleeve is arranged coaxially with the through hole of the roller, and the inner diameter of the spacer sleeve communicates with the inner diameter of the through hole of the roller. One end of the spacer is fixed on the inner wall, and the other end is fixed on the outer wall. Each...
