The invention discloses a pulsed flow-type reaction still. The pulsed flow-type reaction still comprises a still body, an alkaline liquor inlet, a complexing agent inlet, a nickel saline solution inlet, a cobalt saline solution inlet, a manganese saline solution inlet and a material outlet are formed in the still body, and a nickel saline solution feeding pipe, a cobalt saline solution feeding pipe and a manganese saline solution feeding pipe are connected to the nickel saline solution inlet, the cobalt saline solution inlet and the manganese saline solution inlet respectively; electromagneticcontrol valves are arranged on the nickel saline solution feeding pipe, the cobalt saline solution feeding pipe and the manganese saline solution feeding pipe, and a controller is connected to the electromagnetic control valves through control wires. By means of the pulsed flow-type reaction still, quick and frequent switch-on and switch-off of the electromagnetic control valves are controlled bythe controller, and thus a nickel saline solution, a cobalt saline solution and a manganese saline solution form pulsed flow to be injected into the still body, which helps to increase the reaction rate of the metallic saline solutions in the reaction still body with alkaline liquor and a complexing agent, improve the mixing effect, and improve the production efficiency and quality.
