The working principle of the waste lead storage battery crushing and separating system is that the storage battery is crushed by a crusher, the crushed fragments are cleaned by a vibrating screen, lead mud is washed away, the cleaned fragments enter a hydraulic separator and are separated by utilizing the characteristics of different specific gravity of materials, and the separated battery plastic fragments and a lead grid pass through screw conveyor output systems from different outlets of the hydraulic separator.

The specific process is to break the waste lead-acid battery to pieces less than 100mm through the knife edge on the hammer head of the crusher and then enter the vibrating screen, in which a plurality of water spray nozzles are arranged, and the materials are fully cleaned under the double action of water power and vibration.

Lead mud in the battery debris is flushed into the lead mud precipitator through the mesh of the sieve plate, and flocculating agent in an appropriate proportion is added into the lead mud precipitator to promote flocculation and sedimentation of the lead mud, so that a scraper in the lead mud precipitator is convenient to convey to a lead mud stirring tank, then lead mud in the tank is conveyed to a filter press through a lead mud conveying pump, and lead paste is formed after pressure filtration, and the lead paste can be conveyed to a pre-desulfurization system for continuous treatment.

At the same time, polypropylene, heavy plastic and lead grid separated after vibration cleaning are sent to the hydraulic separator by the vibrating screen. Due to the different specific gravity of the materials, the above three materials are sent out from the upper, middle and lower outlets respectively after being separated by the hydraulic separator. In order to ensure the thorough cleaning and separation of various materials, the system carries out secondary cleaning and separation of materials, thus ensuring the cleaning and separation effects of various materials.

The system adopts full-screen monitoring, automatic control and high degree of automation. The main equipment adopts 316L stainless steel with good corrosion resistance. Acid liquor in the whole equipment forms an integral internal circulation system. In addition, acid mist dust removalpipelines are connected to the top of each main equipment in a toxic way, acid mist generated in the production process is pumped to an acid mist cleaning filter for cleaning and filtering, and is discharged into the atmosphere after reaching the standard through detection, thereby preventing air pollution and meeting environmental protection requirements.
