Description

TECHNICAL FIELD

[0002] The liquid used in experiments and production often contains bubbles, especially in high viscosity fluids, which are more difficult to handle.

In order to reduce the bubbles contained in the material, the market has appeared defoaming equipment, which separates the bubbles from the material by rotating centrifugation, thereby realizing the function of defoaming.

[0003] The Chinese patent application file with publication number CN110076009A discloses a contact type friction stirring centrifuge, which comprises a centrifuge main body, and further comprises a main shaft, a bearing seat flange, a friction guide rail, a rotating arm, a clamp, and a self-rotating rubber wheel. The main shaft drives the rotating arm and the clamp to revolve, and then the self-rotating rubber wheel is self-rotated through the contact type extrusion friction between the self-rotating rubber wheel and the friction guide rail, and the self-rotating rubber wheel drives the clamp and the material tank arranged on the clamp to self-rotate. In actual use, in order to generate sufficient friction force between the self-rotating rubber wheel and the friction guide rail, a large pre-tightening force is often applied between the self-rotating rubber wheel and the friction guide rail, so that the self-rotating rubber wheel abuts against the friction guide rail. When the pressure between the self-rotating rubber wheel and the friction guide rail is large, a large internal stress is generated on the overall structure of the centrifuge, which not only affects the service life of the centrifuge, but also easily causes vibration during the rotation of the self-rotating rubber wheel, and further accelerates the wear of the self-rotating rubber wheel and the friction guide rail, thereby further reducing the service life of the centrifuge. Therefore, the centrifuge in the prior art has the problem of poor service life. SUMMARY

[0029] The support seat 22 is fixedly connected with a sliding block 24, and the rotating seat 23 is provided with a sliding groove 25 matched with the sliding block 24. The support seat 22 is provided with a positioning hole 26, and the rotating seat 23 is provided with a positioning member clamped with the support seat 22, the positioning member being a positioning pin 27 slidably connected with the rotating seat 23 and inserted into the positioning hole 26. A locking member is arranged between the rotating seat 23 and the support seat 22, and the locking member is a screw 28 threadedly connected with the support seat 22 and penetrating through the rotating seat 23.

[0030] The rotating seat 23 and the clamp mounting frame 13 are both provided with two, and the two rotating seats 23 are symmetrically arranged with the main shaft 12 as the center. The support seat 22 is fixedly connected with a support plate 29 located between the two rotating seats 23, and the support plate 29 is abutted with two different rotating seats 23 at two ends respectively.

[0031] The driving assembly is installed on the frame 11 and connected with the main shaft 12, and comprises a driving member 14, a driving pulley 15, a driven pulley 16 and a transmission belt 17.

[0035] The rotating axis of the fixture mounting frame 13 is not parallel to the main shaft 12, so that the rotating axis of the fixture mounting frame 13 is not parallel to the rotating axis of the rotating frame, thereby making the rotating directions of the revolution and rotation of the fixture mounting frame 13 different, and further being able to shake the liquid in different directions by the revolution and rotation in different directions, thereby improving the stirring effect of the liquid.

[0036] The main shaft 12 drives the rotating seat 23 to rotate by the rotating arm 21 and the support seat 22 when rotating, and then drives the fixture mounting frame 13 to rotate by the rotating seat 23, thereby realizing the function of driving the revolution of the fixture mounting frame 13.

[0040] The supporting plate 29 provides supporting force for the two rotating seats 23 respectively, can improve the stability of the rotating seat 23, and can improve the service life.
