Abstract

The utility model relates to a winnowing type lead powder machine for producing accumulator lead powder. The existing winnowing type lead powder machine has the defects of low grinding efficiency, low output and large energy consumption. The winnowing type lead powder machine comprises a roller, a blower and a feed funnel which are positioned on one side of the roller, and a powder collector which is positioned on the other side of the roller, wherein the powder collector is connected with a drawing fan. The winnowing type lead powder machine is characterized in that the inner wall of the roller is axially provided with a metal strip. The winnowing type lead powder machine forcibly and nearly drives all lead balls to the optimum height, and then the lead balls fall down. The impact strength of the lead balls on other lead balls in the roller is greatly increased, the grinding efficiency is increased, and thus, the energy consumption is reduced, and the output is increased.

Description

The modified model lead-power machine

Technical field

The utility model relates to a kind of winnowing type lead-power machine of producing storage battery with lead powder.

Background technology

The winnowing type (Tianjin, island formula) of the most of use of the producer of domestic production lead powder at present lead-power machine, promptly the shot (piece) that will be contained in the tube by the cylinder rotation is worn into powder, collect lead powder by wind-force conveying and sedimentation, its operation principle is: during rollers running, shot (piece) rotates with cylinder owing to action of centrifugal force is attached to inner wall of rotary drum, and be brought to optimum height, leave inner wall of rotary drum then and fall along parabolic path, thereby other shot (piece) in the tube is impacted and grinds by self action of gravity.Because the inner wall smooth of cylinder, frictional force between itself and the shot is little, when the outermost layer shot is in best condition of work, all the other each layer shots still are in disadvantageous condition of work, many layer shots all are not brought to optimum height and just leave cylinder wall, the bigger impact dynamics of shot that reduced to other shot in the tube, and grinding efficiency is low, yield poorly, energy consumption is big.In addition, the quill shaft inwall of cylinder causes the internal diameter of quill shaft to diminish owing to lead powder is bonding, influences the powder outlet quantity of cylinder; The lead powder particle diameter that above-mentioned lead-power machine is produced is thicker and inhomogeneous.

The utility model content

Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and the lead-power machine of a kind of low energy consumption, high yield is provided.

The technical scheme that the utility model adopted is: the modified model lead-power machine, and comprise cylinder, be positioned at the air blast of cylinder one side and the powder collector of feed hopper and opposite side, powder collector connects an air exhauster, is characterized in that described inner wall of rotary drum is axially arranged with bonding jumper.Bonding jumper has increased the frictional force of inner wall of rotary drum and shot, pressure is fallen after taking nearly all shot to optimum height, prevent that shot from falling before arriving optimum height, greatly improved the impact dynamics of shot to other shot in the tube, improved grinding efficiency, thereby cut down the consumption of energy and improve output.

Described modified model lead-power machine, cylinder is provided with surge separator near the end cap of powder collector one side, and the lead powder after it will grind separates, and obtains the thin and uniform lead powder of particle diameter.

Described surge separator is made up of front catch member and backup member, front catch member is a circular slab, it has the flanging from the horizontal by acute angle, and flanging is used to cushion the movement velocity of lead powder, and backup member is the pipe fitting of band annular baffle, communicate with quill shaft, annular baffle stretches in the front catch member, and the right side of annular baffle forms a collection meal groove, and backup member is fixed on the end cap, prevent that thicker lead powder from directly not entering in the powder collector through buffering, front catch member is connected with baffle plate.Under the effect of air exhauster, lead powder is brought to surge separator, falling in the collection meal groove than coarse grain footpath lead powder after buffering brought in the powder collector by quill shaft than the lead powder of fine grain, and the lead bullion powder in the collection meal groove grinds under the rotation of cylinder again.

Described modified model lead-power machine, cylinder is provided with scraper near in the quill shaft of powder collector one side, and scraper is L-shaped, and near the inwall of quill shaft, another side is fixed on the inwall of powder collector on one side for it.Along with the rotation of cylinder, and scraper does not rotate, and the lead powder on the quill shaft inwall is wiped off by scraper, solves the bonding problem of lead powder.

The set bonding jumper of the utility model falls after forcing to take nearly all shot to optimum height, has greatly improved the impact dynamics of shot to other shot in the tube, has improved grinding efficiency, thereby cuts down the consumption of energy and improve output.In addition, solved lead powder bonding on the quill shaft inwall, made the lead powder particle diameter of producing thin and evenly.Utilize the utility model, can enable the few 50%-60% of depletion, output can improve 50%-100%.
