Embodiment Construction
[0022] like figure 1 As shown, the rapid synthesis device involved in the method of the present invention includes a reactor and a thickener, and an overflow port is arranged on the reactor, and the overflow port is communicated with the thickener, and the bottom of the thickener is connected with the reactor through a circulating pump, There is a filter rod in the thickener, and the mother liquor collected by the filter rod is connected to a vacuum buffer tank through a flow meter and a pneumatic valve.
[0023] During specific implementation, feed materials into the reactor, and the liquid level in the reactor rises to the overflow port, and then the slurry overflows into the thickener. The nickel-cobalt-manganese ternary solution with a concentration of 70-120g / l, 15-40% NaOH solution, and 5-25% ammonia water are fed into the reactor at a uniform speed through the flowmeter at the same time, and the flow rate of the ternary solution is controlled at 300-1200L / h, Sampling ...
