In the field of modern industrial solid-liquid separation, Automatic Filter Press With Cloths Discharge has the characteristics of high efficiency and automation, so it has become the preferred equipment in many industries. Behind all this efficiency and automation, it is inseparable from its core control system-PLC control system.

As the brain of the automatic cloth unloading filter press, the PLC control system is responsible for receiving signals from input devices such as sensors and buttons, and processing these signals according to the preset program logic, and finally outputting control signals to the actuator to realize the automatic operation of the equipment. In the automatic cloth unloading filter press, the PLC control system is responsible for controlling the main process such as filtration and pressing, and also undertakes important functions such as automatic cloth unloading, fault alarm, and self-protection.

The PLC control system is mainly composed of hardware and software. The hardware part includes PLC host, input and output module, power module, communication module, etc.; the software part includes control program, human-machine interface (HMI), etc. In the automatic unloading filter press, the PLC is connected to the sensors and actuators on the equipment through the input and output modules, collects the equipment operation data in real time, and processes the data and outputs the decision according to the control program. Through the HMI interface, the operator can intuitively understand the equipment operation status, set parameters and diagnose faults.

The control process of the PLC control system in the automatic unloading filter press is as follows: After the equipment is started, the PLC receives signals from the sensor, such as liquid level signals, pressure signals, etc., to determine whether the equipment is in normal working condition; according to the preset process parameters and control logic, the PLC outputs control signals to the actuator, such as starting the feed pump for filtering, driving the clamping mechanism for pressing, etc.; after the pressing is completed, the PLC will control the automatic unloading device to remove the filter cake on the filter cloth; during the whole process, the PLC will continuously monitor the equipment operation status. Once an abnormal situation is found, such as overload, short circuit, etc., the fault alarm and self-protection mechanism will be immediately activated to ensure the safe and stable operation of the equipment.

The application of the PLC control system in the automatic unloading filter press brings many advantages. It improves the automation and production efficiency of the equipment and reduces the labor intensity. Through precise control and monitoring, it ensures the stability and reliability of the filtering and pressing process. The PLC control system also has good scalability and maintainability, which is convenient for subsequent function upgrades and troubleshooting. In the fields of chemical, pharmaceutical, food, environmental protection, etc., more and more automatic unloading filter presses are beginning to use PLC control systems as their core control units.
