The invention discloses a wear-resistant foam pump for conveying thick slurry, and relates to the technical field of foam pumps. According to the wear-resistant foam pump for conveying the thick slurry, through cooperation of the protective filter frame and the collecting assembly, large particle impurities can be blocked when the pump body runs, the phenomenon that an impeller running at a high speed makes contact with the particle impurities, and the phenomenon of excessive wear or collision occurs is avoided, the protective effect of the pump body is improved, and the service life of the pump body is prolonged; and meanwhile, blocked particle impurities can be precipitated and discharged into a collecting box, the maintenance convenience of the pump body is further improved, through cooperation of a plurality of arc-shaped pieces fixed to the outer side of an impeller and conical columns, in the running process of the pump body, the arc-shaped pieces run along with the impeller, and the conical columns run
