Description

Technical Field

[0001] The invention relates to the technical field of automobile battery recycling devices, in particular to an automobile power battery waste liquid recycling device. Background Art

[0002] With the booming development of the automobile industry, the use of automobile batteries is becoming more and more widespread. Automobile batteries produce waste liquid during use, which contains a variety of complex impurities, resulting in many difficulties in the recycling and treatment of automobile battery waste liquid.

[0003] At present, the impurities in automobile battery waste liquid are mainly divided into the following categories: 1. Magnetic metal particle impurities: their sources are mainly the wear and corrosion of the metal parts inside the battery during use, and the metal particles that may be mixed in during the battery manufacturing process. If these magnetic metal particles are not removed in time, it will not only affect the subsequent treatment of the waste liquid, but also may cause heavy metal pollution to the environment; 2. Ordinary particle impurities: including wear particles of the battery shell, sediments generated during the use of the battery, etc. For example, during the battery charging and discharging process, some insoluble compound precipitation may be generated, and these sediments will become part of the ordinary particle impurities. In addition, dust, impurities, etc. in the external environment may also be mixed into the waste liquid during the use of the battery.

[0004] At present, the existing recycling devices lack effective classification and treatment of magnetic metal particle impurities and ordinary particle impurities, and all of them are filtered and removed uniformly. Due to the different properties of the impurities, if they cannot be classified, it will bring great difficulties to the subsequent treatment and resource recovery. On the other hand, these impurities are prone to blockage problems during the recycling process. Impurities of different sizes and shapes are easy to accumulate in filters, filter screens and other parts when flowing through various links of the recycling device, thereby affecting the normal operation of the recycling device, reducing processing efficiency, and may even cause equipment damage and increase maintenance costs.
