Treatment system for removing iron-aluminum-chromium reaction products in leaching solution of laterite nickel ore

A treatment system for removing iron-aluminum-chromium reaction products in a leaching solution of laterite nickel ore, comprising a reaction tank, a lifting assembly, a flushing assembly, and a receiving box, wherein:

• the lifting assembly comprises a rotating shaft, a net pouch, and a connecting rod;
• the rotating shaft is rotatably connected to the reaction tank;
• the rotating shaft is connected to the net pouch via the connecting rod;
• a lifting chamber is formed within the net pouch for salvaging slag phase;
• a rotational path of the net pouch covers and adheres to an inner bottom wall of the reaction tank, and the net pouch can rotate to a first position and a second position above a liquid level inside the reaction tank;
• when the net pouch rotates to the first position, an opening of the net pouch is inclined upwards;
• when the net pouch rotates to the second position, the opening of the net pouch is inclined downwards;
• the flushing assembly is connected to the reaction tank, with a flushing end of the flushing assembly directed at the opening of the net pouch in the first position, to wash off liquid phase adhered to the net pouch and the slag phase;
• the receiving box is slidably connected to the reaction tank and can slide to a position directly below the net pouch in the second position, to receive washed slag phase that gravitationally falls into the receiving box from the net pouch.
