Abstract

The invention discloses a closed loop control system of an ultrasonic separator. A controller is connected with a piezoelectric driving power source of a piezoelectric driving unit; a piezoelectric driver of the piezoelectric driving unit is mounted on a piezoelectric ceramic upper surface; a strain sheet sensor connected with a filter is arranged on a piezoelectric ceramic lower surface; the filter is connected with an amplifier; the amplifier is connected with a controller; the piezoelectric driving unit comprises the piezoelectric driving and is connected with a phase shifter; and the phase shifter is connected with the piezoelectric driver. With the adoption of the manner, the closed loop control system provided by the invention can be used for effectively detecting a vibration frequency and adjusting the vibration frequency by using feedback, so that the vibration frequency of the system can be kept stable. Therefore, the optimal separation effect can be realized.

Description

technical field [0001] The invention relates to the field of separators, in particular to a closed-loop control system of an ultrasonic separator. Background technique [0002] For the separation of oil-solid mixture, it is necessary to achieve a suitable vibration frequency of the mixture in order to effectively separate the oil-solid mixture. At present, the method of separating the oil-solid mixture by open-loop control is mostly used, which cannot achieve precise control of the vibration frequency to ensure the most effective separation of the oil-solid mixture. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a closed-loop control system of an ultrasonic separator, which can effectively detect the vibration frequency and use feedback to adjust the vibration frequency, so that the system can maintain a stable vibration frequency to achieve optimal separation. Effect. [0004] In order to solve the above tec...
