Description
Technical Field
The utility model relates to a copper foil processing technology, concretely relates to lithium electricity copper foil additive automatic control system.
Background
The additive required by the copper foil of the lithium battery is a very important process for producing the electrolytic copper foil, and the control of the content of the additive is a key in the production process of producing the electrolytic copper foil. The control of the content of the additives in the raw foil directly influences the performance of the produced copper foil, and in the additive adding process of the traditional electrolytic copper foil, a metering pump is adopted for adding, the instantaneous flow of the metering pump is pulsating, the precision is not high, the addition is inaccurate, the metering pump reciprocates for a long time, a diaphragm is easy to damage and the like, the process parameters are unstable, and the quality of the copper foil is directly influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an automatic control system for lithium electrolytic copper foil additives is provided, the stability of additive addition is guaranteed.
In order to solve the technical problem, the utility model adopts the following technical scheme: lithium electricity copper foil additive automatic control system, including additive storage bucket, be connected the additive pipeline that is used for carrying the additive with the discharge gate of additive storage bucket, connect the flowmeter that is used for the pump sending the additive on the additive pipeline and is used for metering additive delivery capacity, additive pipeline still is connected with pressure transmitter, additive pipeline is equipped with the return line between pressure transmitter downstream side and additive storage bucket, additive pipeline is equipped with first flow control valve and second flow control valve respectively in the access position upstream side and the downstream side of return line, pressure transmitter, first flow control valve and second flow control valve and PLC communication, pressure transmitter detect pipeline pressure, and when pressure is higher than the setting value, the first flow control valve aperture grow of PLC control, and some additives flow back to the additive storage bucket through the return line, thereby realizing the constant pressure of the additive conveying pipeline.
Optionally, the return pipe is connected to a third flow regulating valve. The pump is a centrifugal pump.
The above technical scheme is adopted in the utility model, at first the aperture through pressure transmitter through PID control governing valve keeps the pipeline constant voltage, has just so guaranteed the stability of additive addition, and the accuracy nature that just more guarantees the flow and add is recorded in the rethread flowmeter.
The specific technical solution and the advantages of the present invention will be described in detail in the following detailed description with reference to the accompanying drawings.
Drawings
The invention will be further described with reference to the accompanying drawings and specific embodiments:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
Referring to fig. 1, lithium electricity copper foil additive automatic control system, including the additive storage bucket, be connected the additive pipeline that is used for carrying the additive with the discharge gate of additive storage bucket, connect the flowmeter that is used for the pump sending the additive on the additive pipeline and is used for the metering agent delivery capacity, the additive pipeline still is connected with pressure transmitter, the additive pipeline is equipped with the return line between pressure transmitter downstream side and additive storage bucket, the additive pipeline is equipped with first flow control valve and second flow control valve respectively at the access position upstream side and the downstream side of return line, pressure transmitter, first flow control valve and second flow control valve and PLC communication, pressure transmitter detection pipeline pressure, when pressure is higher than the setting value, PLC control first flow control valve aperture grow, and partial additive flows back to the additive storage bucket through the return line, thereby realizing the constant pressure of the additive conveying pipeline.
The utility model discloses a principle is at pipeline outlet pipeline installs a pressure transmitter additional, will return the PLC of control room at pressure transmitter, through PLC's PID operation, the aperture of comparison output signal control drive governing valve, and then the flow of control additive, when pressure transmitter pressure is higher than the setting value, PLC control flap aperture grow backward flow to the bucket groove to realize the pipeline constant voltage, keep additive content's closed-loop control, thereby guarantee that the additive flow is invariable. And (4) detecting the additive on line, and feeding back in real time by using a flowmeter.
The backflow pipeline is connected with a third flow regulating valve, and the pump is a centrifugal pump.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
