A paper pulp stirring and separating device for waste paper recovery belongs to the technical field of clean papermaking and comprises a stirring tank, a stirring device, an impurity separation conveying belt assembly, an impurity collecting box, a feeding assembly, a paper pulp storage barrel, a multi-stage separation filtering device, a feeding port and a discharging port. The multi-stage separation filtering device comprises a filtering chamber body, a first filtering unit, a second filtering unit, a third filtering unit and a fourth filtering unit, the first filtering unit, the second filtering unit, the third filtering unit and the fourth filtering unit form a zigzag structure which is folded back in a reciprocating mode, and a discharging port of the feeding assembly is arranged right opposite to the first filtering unit. According to the paper pulp stirring and separating device for waste paper recycling, impurities can be separated out on different filtering units in a layeredmode through a multi-stage filtering structure according to the fact that the screens are sequentially assembled from top to bottom and become denser and denser, and meanwhile the paper pulp stirringand separating device is provided with the efficient stirring device and the metal impurity separating device and is reliable in work.
