Reliably-connected wear-resistant ore pulp stirrer impeller

The invention discloses a reliably-connected wear-resistant ore pulp stirrer impeller which comprises a hub, a first connecting plate, a second connecting plate, connecting bolts, rib plates and blades. The inner diameter of the hub is matched with the stirrer shaft, and the hub is fixed on the stirrer shaft; the first connecting plates are welded to the hub, and the number of the first connecting plates is four. The second connecting plates and the first connecting plates are fixed through connecting bolts, and the number of the second connecting plates is in one-to-one correspondence with the number of the first connecting plates. One blade is welded on each second connecting plate; rib plates for improving the deformation resistance strength of the blades are arranged on the two sides of each blade. The invention aims to provide the wear-resistant ore pulp stirrer impeller which is reliably connected, and particularly, the service life of the stirrer impeller is prolonged by improving the blade connecting
