The invention provides a comprehensive recycling device for waste lithium batteries. An insulation bin, a discharge bin and a crushing bin are sequentially placed from top to bottom, and the insulation bin, the discharge bin and the crushing bin are communicated in sequence. Discharge valves are arranged between the insulation bin and the discharge bin and between the discharge bin and the crushing bin. The discharge bin is provided with a salt solution injection pipe. The bottom of the crushing bin is closed by a first sieve. A filtering device is placed below the crushing bin. A second sieve, a third sieve and a fourth sieve are sequentially arranged on the filtering device from top to bottom. At least one carbonate-containing aqueous solution spraying pipe is arranged between the thirdsieve and the fourth sieve on the filtering device. The bottom of the filtering device is communicated with a calcium hydroxide adsorption column, an aluminum hydroxide adsorption column and a distillation chamber in order. T
