Wastewater recovery device for chemical nickel production

The utility model discloses a waste water recovery device for chemical nickel production, which comprises a bottom plate, a stirring rod is arranged in a filter box component, so that nickel-containing waste water accelerated by the stirring rod reacts with caustic soda flakes to generate nickel hydroxide which is precipitated in the filter box component, and the nickel hydroxide is separated from the filter box component. Piston rods of two sets of electric hydraulic rods stretch out and draw back to drive a box cover to ascend, a filter box assembly arranged at the bottom of the box cover is separated from the treatment box along with ascending of the box cover, and by rotating a net-shaped filter box, an annular inner thread section at the upper end of the net-shaped filter box is matched with an annular outer thread section at the bottom of an annular connecting plate, so that the net-shaped filter box is separated from the annular connecting plate; furthermore, the nickel material precipitated in the net
