When the transmission motor drives the screening tank to rotate at a high speed, the strain raw material and the nutrient solution can be fully stirred and centrifuged. After centrifugation, the strain liquid and impurities can be allowed to stand and separate by standing. The staff opens the strain discharge port and the material discharge port in turn to separate the strain liquid and impurities and transport them out. The operation is convenient and the efficient screening of the strain can be ensured.

[0004] However, since the separation paddles arranged inside the inner tank in the above-mentioned device are fixed, when the inner tank rotates, the separation paddles will rotate synchronously with the rotation of the inner tank and the bacterial strain raw materials inside the inner tank, resulting in poor separation effect of the bacterial strain raw materials by the separation paddles, and further, the bacterial strain raw materials and the nutrient solution cannot be fully mixed, resulting in poor screening effect of the bacterial strains.

The above-mentioned scheme solves the problem that the separation paddle arranged inside the inner tank in the above-mentioned device is fixed, resulting in that when the inner tank rotates, the separation paddle will rotate synchronously with the rotation of the inner tank and the bacterial raw material inside the inner tank, thereby resulting in poor separation effect of the bacterial raw material by the separation paddle, and further the bacterial raw material and the nutrient solution cannot be fully mixed, resulting in poor screening effect of the bacterial strains. It can be understood that the above-mentioned scheme can be used for the centrifugal separation of bacterial raw materials and bacterial strains in the soil microbial strain continuous screening device, and can also be used to solve the problem that the bacterial liquid is not convenient to be discharged from the screening tank.

[0026] According to this specific embodiment, the separation rod 104 and the screening tank 102 form a differential rotation, so that the separation rod 104 has a better mixing effect on the bacterial strain raw material and the nutrient solution, thereby achieving a better screening effect of the bacterial strain.

When centrifuging is performed, the screening tank 102 is driven to rotate by the driving assembly, and the rotation of the screening tank 102 drives the ring gear 105 to rotate through the hollow shaft 103. The ring gear 105 drives the separation shaft 106 and the separation rod 104 to rotate through the differential transmission assembly, so that the separation rod 104 and the screening tank 102 form a differential rotation, so that the separation rod 104 has a better mixing effect on the bacterial strain raw material and the nutrient solution, thereby making the bacterial strain screening effect better.

[0033] When using a soil microorganism strain continuous screening device of the present embodiment, the nutrient solution and the strain material are respectively placed in the screening tank 102, and the drive motor 108 is then started to drive the drive shaft 109 to rotate, and the drive shaft 109 drives the screening tank 102 to rotate, and the screening tank 102 drives the hollow shaft 103 fixedly connected thereto to rotate, and the rotation of the hollow shaft 103 then drives the ring gear 105 to rotate, and the ring gear 105 drives the transmission gear 111 and the transmission shaft 110 to rotate by meshing with the transmission gear 111, and since the transmission shaft 110 is fixedly connected to the first pulley 112, the rotation of the first pulley 112 then drives the second pulley 113 to rotate through the transmission belt 114, and the second pulley 113 is fixedly connected with the separation shaft 106, thereby driving the separation shaft 106 to rotate in the hollow shaft 103 through the bearing 107, and the separation shaft 106 further drives the separation rod 104 to rotate in the screening tank 102, thereby the separation rod 104 and the screening tank 102 form a differential rotation, and when the screening tank 102 centrifuges the bacterial raw material and the nutrient solution, the separation rod 104 mixes and stirs the bacterial raw material and the nutrient solution. After the centrifugation is completed, the bacterial liquid and the impurities of the bacterial raw material are separated by standing, and then the bacterial liquid is discharged through the bacterial liquid discharge device, thereby forming a differential rotation through the separation rod 104 and the screening tank 102, so that the separation rod 104 has a better mixing effect on the bacterial raw material and the nutrient solution, thereby making the bacterial screening effect better.
