Description

Technical Field

[0001] The invention relates to the field of lead-acid battery recycling, and in particular to a high-speed sorting device suitable for recycling waste lead-acid batteries. Background Art

[0002] Lead-acid batteries are widely used as energy storage devices. If they are not properly recycled after a certain number of years of use, they will cause serious harm to the environment. Lead-acid batteries contain a large amount of harmful substances such as lead and sulfuric acid. Lead will seep into the soil and groundwater, causing soil and water pollution. Sulfuric acid is highly corrosive and will corrode surrounding objects and cause safety accidents. In addition, if materials such as the plastic shell in the lead-acid battery are not recycled, it will also cause a waste of resources.

[0003] A Chinese patent discloses a sorting device for recycling waste lead-acid batteries (application number: 2022108261165), which uses water flow to wash the battery shell fragments to improve the efficiency of washing the battery shell fragments. After washing, due to the water jump phenomenon, the battery shell fragments are gathered together, and then the battery shell fragments are taken out and transported out by a robotic arm, thereby improving the sorting efficiency of the battery shell fragments;

[0004] However, the above patent only washes and sorts the shell fragments of lead-acid batteries, and it is difficult to separate the plastic and metal in the crushed lead-acid battery fragments.

[0042] The working process and principle of the present invention are as follows:

[0043] The lead-acid battery waste after the acid is discharged and crushed is continuously conveyed to the inside of the sorting barrel 1 through a belt conveyor or a screw elevator. The internal components of the lead-acid battery waste are metal plates and plastic shells. At this time, water is added to the inside of the sorting barrel 1 through a water pipe. The metal plate fragments inside the sorting barrel 1 sink to the bottom of the sorting barrel 1, and the plastic fragments float on the water surface. Water is continued to be added until the water overflows the sorting barrel 1. The plastic fragments floating on the water surface and the water overflow the sorting barrel 1 at the same time and fall into the inside of the annular inclined trough 12, and then flow to the inside of the plastic separation barrel 19 through the annular inclined trough 12 until the water level inside the plastic separation barrel 19 rises to the midline of the extended discharge nozzle 20, and then the solenoid valve 25 is opened to discharge the water in the plastic separation barrel 19 to the residual water pool 53, and at the same time, the plastic fragments floating above the extended discharge nozzle 20 are fished out;

[0044] When the metal scraps sink downward in the sorting barrel 1, they are guided by the annular inclined plate 15 and fall into the interior of the scroll gathering plate 18. At this time, the stepper motor is started to drive the first transmission member 16 to rotate, the first transmission member 16 drives the second transmission member 17 to rotate, and the second transmission member 17 drives the scroll gathering plate 18 below it to rotate, so that the metal scraps inside the scroll gathering plate 18 are gathered to the center for easy unloading. Then the first drive motor 23 is started, and the first drive motor 23 drives the slurry pump 22 to transport the metal scraps at the bottom center of the sorting barrel 1 together with water to the Above the filter cloth 40, the second drive motor 34 is started to drive the roller 37 to rotate, and the roller 37 drives the transmission belt 39 and the filter cloth 40 on the outside thereof to rotate, so that the filter cloth 40 transports the water-containing metal fragments thereon to the other end, and at the same time, the water in the metal fragments is filtered through the filter cloth 40 and flows into the water collecting plate 35, and then flows out through the water outlet square pipes 36 at both ends of the water collecting plate 35, and the metal fragments are transported to the top of the belt conveyor 6 through the filter cloth 40 to complete dehydration, and at the same time, the scraper block 41 scrapes off the metal fragments on the outside of the filter cloth 40;

[0045] The water filtered by the scraper 41 flows into the interior of the sedimentation box 51 through the water outlet square pipe 36. At this time, a small amount of fine metal fragments contained in the water continue to be deposited at the bottom of the sedimentation box 51, and the water flow above the water baffle 52 flows into the interior of the residual water pool 53. Then, the water pump 54 is started to transport the water in the residual water pool 53 to the interior of the sorting bucket 1 through the water inlet pipe 55, thereby completing the cyclic sorting operation of the waste after the lead-acid battery is crushed.
