Lead-acid storage battery recovery wastewater treatment device

Abstract

The invention discloses a lead-acid storage battery recovery wastewater treatment device which can improve the filtering effect of impurities in wastewater through the cooperative use of a first filtering grid, a second filtering grid, a first fixing seat, a second fixing seat and a spraying seat. Through cooperative use of a storage net, a storage ring, a first adsorption block and a second adsorption block, filtered impurities can be conveniently and rapidly treated. A first treatment tank is opened through a first upper top plate, and the first filtering grid and the second filtering grid are sequentially separated from the inner wall of the first treatment tank and cleaned. A second fixing plate is moved towards the side away from the second fixing seat. The second fixing plate is lifted upwards, and the storage net and sediment are moved upwards to the outside of the first treatment tank together for treatment, so that the impurity treatment efficiency can be effectively improved.The problems that the filtering efficiency of impurities in wastewater is poor and the filtered impurities are inconvenient to treat can be solved in all aspects disclosed by the invention.

Description

technical field [0001] The invention relates to the technical field of lead-acid battery recycling, in particular to a wastewater treatment device for recycling lead-acid battery. Background technique [0002] A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main component of the positive and negative electrodes is lead sulfate; the nominal voltage of a single cell lead-acid battery is 2.0V, It can be discharged to 1.5V and charged to 2.4V; in applications, six single-cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery, and the waste water generated during the recycling of lead-acid batteries needs to be treated to avoid polluted environment.

Problems solved by technology

[0005] The problem solved in one aspect of the disclosure of the present invention is: how to solve the problem of poor filtration efficiency of impurities in waste water; The combined use of the spray seat can improve the effect of filtering impurities in the wastewater; the wastewater is transported to the first treatment tank through the first upper conduit, and the wastewater is coarsely filtered through the coarse filter mesh in the first filter grid in turn, so that the wastewater in the wastewater Larger flocs are filtered through the coarse mesh for primary filtration, and secondly filtered through the filter mesh in the second filter grid, so that smaller flocs and particles in the wastewater are filtered for the second time, and the filtered wastewater continues to Flow downwards; through several nozzles, evenly spray chemicals into the first treatment tank, chemical reactions between the chemicals and waste water will form insoluble sediments, which will sink and accumulate on the storage net, through the physical filtration of waste water and The combination of chemical filtration can effectively improve the filtration effect of impurities in wastewater, and solve the problem of poor filtration efficiency of impurities in wastewater in existing solutions;

[0006] The problem solved by another aspect of the present invention is: how to solve the problem that the filtered impurities are inconvenient to handle; through the cooperative use of the set storage net, storage ring, first adsorption block, and second adsorption block, it can be conveniently and quickly The filtered impurities are processed; the first treatment tank is opened through the first upper top plate, the first filter grid and the second filter grid are separated and cleaned from the inner wall of the first treatment tank in turn, and the second fixed plate is Move away from the side of the second fixed seat, through the rotation of the first clamping column and the second clamping column, the top column is separated from the card slot; by pulling the second fixing plate upward, several second adsorption blocks are connected to the first The first adsorption block is separated, and the storage net and sediment are moved up to the outside of the first treatment tank for treatment, which can effectively improve the treatment efficiency of impurities and solve the problem of inconvenient treatment of filtered impurities in the existing scheme
