[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figure 1-3As shown, a movable positioning mechanism for adjusting the height of the agitator shaft comprises a compression flange base 7, the bottom surface of the groove of which is connected to a compression flange sealing ring 6. A two-petal compression flange 4 is connected to the groove of the compression flange base 7. The inner groove of the compression flange base 7 is tapered; the lower end of the two-petal compression flange 4 is tapered. The outer wall of the shear shaft 2 is connected to a shaft sealing ring 3, which extends through the two-petal compression flange 4. The shaft sealing ring 3 is connected to the inner wall of the two-petal compression flange 4. The upper end of the shear shaft 2 is connected to the motor 1. The two-petal compression flange 4 is connected to the groove of the compression flange base 7 via screws 5.
[0019] Specifically, the lower end of the shear shaft 2 is connected to the shear stirring stator 9, and the shear stirring stator 9 is matched with the shear stirring rotor 10. The output end of the motor 1 is connected to the shear shaft 2 through a connecting pin 8.
[0020] Specifically, the lower end surface of the compression flange base 7 is connected to the lower flange 11 at the upper end of the outer wall of the barrel body and is fixed by a movable bolt group 12. A flange sealing ring 13 is provided between the compression flange base 7 and the lower flange 11.
[0021] During installation, the shaft sealing ring 3 is inserted into the shear shaft 2, and the shear stirring stator 9 is used to install it on the shear shaft 2. Then the shear stirring rotor 10 is matched with the shear stirring stator 9 and installed. The clamping flange sealing ring 6 is placed in the clamping flange base 7 groove, and the shear shaft 2 is inserted into the clamping flange base 7 groove for temporary support. Next, the two-petal clamping flange 4 is clamped to the shaft sealing ring 6, and the two-petal clamping flange 4 and the clamping flange base 7 conical surface matching design structure are used for installation. Then the screw fastening assembly 5 is used to lock the two-petal clamping flange 4. Tightening the screw fastening assembly 5 will move the two-petal clamping flange 4 along the conical surface. This can achieve a high sealing function for the shear shaft 2 and the shaft sealing ring 3, and the sealing performance of the sealing ring is very good; it is completely guaranteed to be leak-free, and is isolated from other external environments, will not contaminate materials, ensure sterility, and the height of the stirring shaft 2 is adjustable. When adjusting the height of the agitator shaft 2, remove the screws 5 securing the two-piece clamping flange 4 to loosen the agitator shaft 2, then raise or lower the height of the shearing machine. Once the desired height is reached, tighten the screws 5 of the two-piece clamping flange 4 to secure and seal the agitator shaft 2. Next, install the flange sealing ring 13 into the sealing groove of the clamping flange base 7, then align the assembled clamping flange base 7 and other components with the lower flange 11. After adjusting the orientation, use the flexible bolt assembly 12 to compress and seal the clamping flange base 7 and the lower flange 11 together. Then, connect the motor 1 to the shear shaft 2 using the shear shaft and shear motor connecting pin 8.
[0022] The movable positioning mechanism with adjustable stirring shaft height has a reasonable overall structural distribution. The stirring shaft 2 is height-adjustable, and can perform high-shear homogenization on materials in different working conditions and different tank sizes and depths. The quality rate of material products is greatly improved, and the overall strength meets a wider range of working conditions. The sealing performance is excellent, and the rubber sealing ring is tightly pressed against the shear shaft to ensure no leakage and isolation from other cavities. The sterility meets the use requirements, ensuring that there is no risk of contamination of the material.
