[0042] The support column 5 is arranged at one end of the top of the bottom plate 1, and a hopper 6 is fixedly connected thereto, and the hopper 6 is used to carry phosphate rock powder;

[0043] The material pipe 7 is fixedly arranged on the outer side wall of the hopper 6 near the bottom of the hopper 6, and the phosphate rock powder in the hopper 6 enters the stirring mechanism through the material pipe 7;

[0044] The stirring mechanism 2 is fixedly arranged at one end of the top of the base plate 1 away from the support column 5, and mainly includes an operating pool, a first stirring component and a second stirring component, wherein the first stirring component and the second stirring component are fixedly arranged in the operating pool, and the first stirring component is arranged in the second stirring component, and the slurry is fully stirred under the cooperation of the first stirring component and the second stirring component.

A slurry discharge pipe 11 is fixedly arranged at the free end of the slurry pump 10 . The finished slurry is discharged from the slurry discharge pipe 11 through the slurry pump 10 .

[0046] First, the phosphate rock powder in the hopper 6 is diluted with water and enters the second stirring component set in the working pool through the material pipe 7. At the same time, the first stirring component and the second stirring component are started, and the first stirring component and the second stirring component rotate in opposite directions. The slurry is mixed and stirred by the relative rotation of the first stirring component and the second stirring component. After the slurry is fully mixed, the more delicate slurry leaves the second stirring component and enters the working pool. The slurry in the working pool is fully stirred again under the action of the second stirring component, and then the finished slurry is discharged from the slurry discharge pipe 11 through the slurry pump 10. The stirring structure of the present application can realize the function of fully stirring the slurry, which makes up for the defects of insufficient stirring of the slurry and poor stirring effect in the prior art.

[0047] Specifically, the four corners of the top of the bottom plate 1 are penetrated with pins 12, and the bottom ends of the pins 12 extend to the ground and are inserted into the ground, so that the bottom plate 1 is fixed to the ground, which effectively increases the stability of the repulping device during use and effectively prevents the repulping device from shaking due to external forces. A support column 5 is provided at one end of the top of the bottom plate 1, and a hopper 6 is fixedly provided on the top of the support column 5.

A material pipe 7 is fixedly arranged on the circumference of the hopper 6 at one end adjacent to the bottom of the hopper 6. The material pipe 7 is cylindrical and L-shaped. The free end of the material pipe 7 extends to the inside of the stirring mechanism. A connecting plate 8 is arranged on the circumferential surface of the material pipe 7. One end of the connecting plate 8 is fixedly connected to the material pipe 7, and the other end is fixedly connected to the support column 5.
