The invention relates to a lubricating oil stirring tank. The lubricating oil stirring tank comprises a tank body. A feeding opening is formed in the upper portion of the tank body, a discharging opening is formed in the lower portion of the tank body, supporting legs are arranged at the lower portion of the tank body, a motor is arranged at the upper portion of the tank body, and the motor is connected with a shaft; blades for stirring lubricating oil are arranged on the shaft, the blades arranged on the shaft include the blade A and the blade B, the blade A is arranged at the middle end of the shaft, the blade B is arranged at the lower end of the shaft, the blade A is in a paddle type, and the blade B is in a downward anchor type; a clamping sleeve is arranged outside the tank body, and a clamping sleeve inlet and a clamping sleeve outlet are formed in the clamping sleeve; a man hole is formed in the tank body; the motor is connected with the shaft through a coupler. The lubricating oil stirring tank is used for stirring base oil and an additive of the lubricating oil; as the blades on the shaft include the paddle-type blade and the anchor-type blade, stirring is more even, and the stirring effect is better.
