The input end of the first pump body 201 is fixedly connected to the first input pipe 202, and the first input pipe The other end of 202 extends to the interior of the outer tank body 101 and is connected to the first inlet 204.

The input end of the second pump body 301 is fixedly connected to the second input pipe 302, and the other end of the second input pipe 302 extends To the inside of the inner tube 102 and connected to the second inlet 304, the second inlet 304 is located at the middle and upper liquid level of the outer tank body 101, the second inlet 304 is set at the middle end of the outer tank body 101, the output end of the second pump body 301 is fixedly connected to the second output pipe 303, the other end of the second output pipe 303 also extends to the inside of the outer tank body 101 and is connected to the second outlet 305, the second outlet 305 is set at the lower end of the outer tank body 101, to achieve the effect of coordinated and uniform mixing of the outer tank body 101 and the second circulation pump 300.

[0027] Among them Figure 2 and Figure 5 As shown, the outer tank body 101 is made of high-strength and corrosion-resistant stainless steel material to ensure the stability and durability of the outer tank body 101, the diameter of the inner cylinder 102 is set to a, a ≥ 600 mm, and the height of the inner cylinder 102 is set to h, which is 7 m. The size of the inner cylinder 102 is limited so that an appropriate distance can be maintained between the inner cylinder 102 and the outer tank body 101 to ensure that the liquid can flow smoothly between the two. The shapes of the outer tank body 101 and the inner cylinder 102 are both set to be cylindrical, which can minimize the resistance to liquid flow.

[0028] Among them Figure 1 and Figure 2 As shown, a bypass port is provided at the lower end of the outer tank body 101, and a mixing tube 306 is provided between the bypass port and the second input pipe 302. A regulating valve is provided on the outside of the mixing tube 306, so that the lower layer liquid in the outer tank body 101 can also enter the second pump body 301 through the second input pipe 302, so as to achieve the effect of mixing the upper layer liquid and the lower layer liquid in the second pump body 301 and then discharging from the second outlet 305, and utilizing the internal space of the second pump body 301 for strong mixing.

The middle and upper layer liquid enters the second input pipe 302 through the second inlet 304, and is then discharged upwardly through the second outlet 305. The lower layer liquid enters the mixing pipe 306 through the bypass port, mixes with the middle and upper layer liquid in the second input pipe 302, and is then discharged through the second outlet 305. The first circulation pump 200 pushes the liquid downward, and the second circulation pump 300 pushes the liquid upward, so that the liquid inside the outer tank body 101 can form a complex flow pattern, including spiral rise, diffusion all around, etc., which has a good liquid mixing effect.
