Oscillation cross section adjustable oscillator

Abstract

The invention provides an oscillation cross section adjustable oscillator. An up-down sliding mechanism comprising a guide slide rail and a guide slide block is adopted between an oscillation support and a fixed mount; and in a process of sliding up and down, the guide rail is free from external force, so that the running abrasion and the sliding friction resistance can be greatly reduced, defects of stress deformation and the like of a guide rod in the prior art can be eliminated, the operation is stable and reliable and the service life is long. A mounting column in a separating funnel positioning device can slide in an adjustment arc chute of an oscillation box along a lower rotary pin shaft, so that the mounting column is in an inclined state; an adjustment range of an angle of inclination is determined by an arc angle of the adjustment arc chute, so that to-be-oscillated bottle body liquid is properly tilted according to requirements of a tester, the surface area of the liquid stored in an actually oscillated bottle is increased, the oscillation uniformity of the to-be-oscillated liquid is improved, and the oscillation homogenization time is also reduced. A motor is controlled by avariable frequency electric actuator to ensure that the oscillation frequency can be changed, and the oscillator has a variable frequency and is efficient, energy-saving and reliable.

AI Technical Summary

Problems solved by technology

Since the separatory funnel is fixedly installed on the separatory funnel positioning device during the oscillation homogenization process, the bottom of the separatory funnel is parallel to the bottom of the chassis, and the oscillation area of ​​the liquid to be oscillated is the cross-sectional area of ​​the diameter of the filling bottle, which actually participates in the oscillation The area is small and cannot be adjusted, which will inevitably lead to longer oscillation time

The main cause of high failure rate, short service life and poor reliability is that the structure of the guiding mechanism between the vibrating frame and the fixed frame is inconsistent. , a guide rod usually cooperates with three guide wheels, and the three guide wheels are respectively arranged on both sides of the guide rod, forming a three-point contact between the guide wheel and the guide rod. During the oscillation process, the guide rod is subjected to alternating pressure, The guide rod is deformed, which will increase the sliding resistance of the vibration frame up and down, and the vibration frame will not vibrate smoothly. If it is light, it will cause the vibration frequency to be unstable.
