Technical Field

The invention relates to the technical field of production of lead-acid storage batteries, in particular to a device for reducing acid leaching lead slime.

Background

With the increasingly saturated market of lead-acid storage batteries, each large lead-acid storage battery manufacturer can fight against the price of the battery in order to expand the market share of the manufacturer, and a batch of small enterprises break the production due to the fact that the quality or the cost of the battery has no advantage in the process, so that the control of the manufacturing cost of the battery becomes an urgent task in the lead-acid storage battery industry under the condition of ensuring that the quality of the battery is not changed.

The lead plaster is coated on the grid in the production process of the polar plate, the strength is poor, the subsequent operation is inconvenient, a compact lead sulfate protective layer is generated by uniformly spraying sulfuric acid on the surface of the polar plate, on one hand, the lead sulfate has no viscosity, and after the polar plate is quickly dried, the plate is not stuck when the green polar plate is rolled up and put on a curing frame; on the other hand, the lead sulfate can well keep the moisture in the polar plate, so that the polar plate is well solidified, the strength of the polar plate is enhanced, and the subsequent processing is convenient. However, in the process of spraying sulfuric acid on the surface of the polar plate, 2% -3% of lead mud can be generated due to the fact that acid spraying liquid directly impacts the surface of the polar plate, and the lead mud and waste acid in the acid spraying process are collected in a sedimentation tank, so that the lead mud is high in lead sulfate content and cannot be directly recycled. In general, a small part of enterprises choose to directly sell the lead slime as waste, but the manufacturing cost of the battery is greatly increased.

Therefore, the method for reducing the lead slime amount generated in the plate coating process of the polar plate is a feasible scheme for controlling the battery manufacturing, but no device capable of reducing the lead slime amount generated in the plate coating process of the polar plate exists in the existing market.

For example, Chinese patent publication numbers are: CN207126194U, a filtering and recycling device for coated plate acid and lead slime announced in 2018, 3, 23 and relates to the field of storage batteries; the recycling device comprises a recycling bin, a water pump and a filter press, wherein a plurality of acid discharge pipes are sequentially arranged on the left side edge of the recycling bin from top to bottom, acid discharge valves are respectively arranged on the acid discharge pipes, the acid discharge pipes are connected to a waste acid pipeline, and the water pump is connected to the waste acid pipeline; a lead slime pipeline is arranged at the bottom of the right side edge of the recovery barrel, a lead discharging valve is arranged on the lead slime pipeline, and the lead slime pipeline is connected to a lead slime collecting pool through a filter press; although the utility model provides a scribble filtration recovery unit that board drenched sour and lead slime through setting up the row's of co-altitude sour pipe, falls the spent acid as far as, and separation spent acid and lead slime can effectively solve lead-containing suspension acidizing fluid polluted environment, the problem that recovery cost is high, area is big, have simple structure, and recovery cost is low, and resource recovery rate is high, the effectual advantage of energy-concerving and environment-protective, but can not reduce the lead slime volume that the polar plate scribbles the board in-process and produce.
