Abstract

The invention discloses a combined water treatment impeller. The combined water treatment impeller comprises an impeller body, wherein the impeller body is a ring body, an inner cavity of the ring body is hollow, the ring body is formed by splicing an upper ring body and a lower ring body in the vertical direction, at least four blade bodies are uniformly distributed on the edge of the impeller body at intervals, and an inner cavity of each blade body is hollow. By adopting a split-type assembled structure, the combined water treatment impeller is ingenious in concept, the splicing process is advanced, the assembled structure is accurate in positioning, and the inner cavity of the assembled large-sized water treatment impeller is hollow, so that a sufficient floating force can be provided, and the overall design of the product is reasonable; compared with the prior art, the combined water treatment impeller is more suitable for a large-sized water treatment device.
