The working principle of the ultrasonic-based pipeline anti-settling system is as follows: when lithium cell coating slurry stops production, lithium cell slurry in the communicating pipe 40 is in quiescent condition, can produce the phenomenon of subsiding, opens ultrasonic transducer 30 is in through the ultrasonic wave cavitation, acceleration action and direct current effect etc. in the lithium cell slurry simulate lithium cell slurry is at the torrent of flow in-process and phenomenon such as indiscriminate flow, indirect messenger the lithium cell slurry of subsiding in the communicating pipe 40 is dispersed, emulsified, is peeled off, thereby reaches and prevents the lithium cell slurry is in because of the emergence of the produced settlement problem of stewing in the communicating pipe 40.
The ultrasonic-based pipeline anti-settling system is used for simulating phenomena of turbulence, turbulent flow and the like of the lithium battery slurry in a flowing process through cavitation, acceleration, direct current and the like of ultrasonic waves, and preventing the lithium battery slurry from settling in the communicating pipeline; the embodiment avoids the problems of time and labor waste caused by disassembling the pipeline 40 for cleaning; ultrasonic equipment is used in this embodiment, and equipment cost is low, easily builds the system, the popularization of this embodiment of being convenient for.
As shown in fig. 1, the ultrasonic-based pipe anti-settling system further includes an ultrasonic generator 50 and a Programmable Logic Controller (PLC), wherein the PLC controls the switching and frequency of the ultrasonic generator 50 for the operation of the ultrasonic transducer 30.
The ultrasonic transducer 30 is externally connected with the ultrasonic generator 50 and the PLC, and the PLC controls the on/off and the frequency of the ultrasonic generator 50, where it should be noted that the ultrasonic transducer 30 is electrically connected with the ultrasonic generator 50, in this embodiment, the ultrasonic transducer 30 and the ultrasonic generator 50 are electrically connected in a manner of an electric wire, and may be connected in parallel or in series, and may be set according to actual situations, which is not limited herein.
As an example, it is preferable that the ultrasonic transducer 30 is turned on and off alternately by the ultrasonic generator 50 when the production is stopped, and is turned on or off at preset time intervals, so that the sedimentation problem of the lithium battery slurry can be further reduced in a normal production state. When the ultrasonic generator is not in production, that is, in a production stop state, the time interval between the on and off states or the on time of the ultrasonic generator 50 is shortened to improve the anti-settling function of the ultrasonic wave, and the change of the frequency is matched to cope with various different operation conditions, so that the adaptability of the ultrasonic generator is high.
As an example, the ultrasonic generator 50 is turned on for 5s to 30s each time, and turned off for 5min to 30min each time, and the turning on and the turning off are alternately performed. The time for turning on and off the ultrasonic generator 50 can be set according to different lithium battery slurries, and is not limited herein; in addition, when the ultrasonic generator 50 is turned on, the operation of the ultrasonic transducer 30 is frequent, and the frequency can be set according to different lithium battery pastes, which is not limited herein.
