Description

Lead plaster collecting equipment and spraying circulating system of waste lead-acid storage battery Technical Field The utility model relates to the technical field of recovery treatment of waste lead-acid storage batteries, in particular to lead plaster collecting equipment and a spraying circulation system of waste lead-acid storage batteries. Background Lead plaster in lead-acid batteries is the most important component, and accounts for about 50% of the total weight of the battery. Therefore, the recovery rate of the lead plaster directly influences the economic benefit of the production enterprises. In the lead-acid storage battery recovery process, the collection of the lead plaster is realized by disassembling the broken spraying system. And cleaning the lead plaster in the materials by high-pressure liquid, and then collecting and drying the lead plaster by a lead plaster collecting system. In the production process, the cleaning degree of spray water in the spray system directly influences the cleaning effect of the blocky materials. The traditional water purification and circulation system adopts a two-stage water tank with a bidirectional spiral at the bottom to collect suspended matters in the spraying water. This system collects the sediment in the middle of the tank, and then the sediment is extracted by a vertical pump and conveyed to a tank for collection. In this way, the spray water is purified, becomes clear and clean, and can be reused in the spray system. However, there are some problems in practical application of this circulation system: first, since the precipitate in the circulating water is a dilute material having a certain concentration, the spiral collection efficiency is low. In the case where the amount of the circulating spray water is large, the amount of the precipitate increases drastically, causing the water to become cloudy. This directly affects the cleaning effect, making it difficult for the lead plaster to be effectively cleaned. Secondly, in this process, the precipitated thick material needs to be extracted from the bottom of the tank by a vertical pump. When the sediment amount is more, the conveying capacity of the pump is often not kept up, and the liquid of the spraying system becomes turbid, so that the effect of cleaning the lead plaster cannot be achieved. These factors can severely affect the proper operation of the dismantling system. Practice shows that after the dismantling system works continuously for about half a month, sediment in the circulating water tank is piled up, so that the whole system has to be stopped. This not only reduces production efficiency but also increases the cost of equipment maintenance and cleaning. In addition, lead plaster collection device among the prior art often structure complicacy, clearance maintenance difficulty, and collection efficiency is not high. This further exacerbates the technical difficulties in the recovery process of lead-acid batteries. In view of the above, there is a need in the art for improvements.
