Factory-made at a lower price, new design automatic hydraulic plate-and-frame filter press
The automatic hydraulic system is the hallmark feature of this machine, and its operation process is precise and reliable:
Automatic compression
Start-up: The operator presses the "Compression" button, the motor starts, and the hydraulic pump begins to operate.
Action: Under the action of the pump, the hydraulic oil enters the hydraulic cylinder and pushes the piston rod to extend forward.
Closing: The piston rod drives the movable pressing plate, pressing all the filter plates and filter frames towards the fixed end, thus forming a sealed filter chamber.
Achieving the set pressure: When the system pressure reaches the upper limit set value of the electrical contact pressure gauge, the hydraulic pump automatically stops working, the pressing process is completed, and the equipment enters the waiting for filtration state.
Automatic Pressure Maintenance
Pressure maintenance: During the feed filtration process, due to the resistance of the material, there is a tendency for the filter chamber to expand. The relief valves and hydraulic control check valves inside the hydraulic system will automatically compensate and lock, ensuring that the clamping force remains stable within the required range throughout the filtration cycle, preventing material spraying and pressure leakage, and guaranteeing the filtration effect and safety.
Automatic release
Release pressure: After the filtration process is completed, the operator presses the "Release" button.
Return: The hydraulic system switches direction. Hydraulic oil enters from the other side of the hydraulic cylinder, causing the piston rod to retract.
Stop: The pressing plate of the activity automatically stops when it retreats to the position set by the limit switch, preparing for subsequent manual or mechanical auxiliary discharging.
1. Frame part: includes thrust plate, base, main beam, and movable pressing plate.
2. Filtration section: Composed of multiple orderly arranged filter plates and filter boxes.
3. Automatic Hydraulic System:
Hydraulic Station: Composed of a motor, an oil pump, an overflow valve (for pressure regulation and safety), a directional control valve, a hydraulic check valve (for pressure retention), and an oil tank, it is the power core of the system.
Hydraulic cylinder: An actuator that converts hydraulic energy into mechanical energy for linear motion.
4. Electrical Control Box: Integrates PLC or relay control circuits, as well as electric contact pressure gauges, for controlling the start and stop of the motor, as well as the automatic clamping and holding pressure logic.
5. Others: Feed pipes, collection tanks, etc.
This model is applicable to all industrial fields that require solid-liquid separation. Especially in those scenarios where there are high requirements for the sealing pressure of the filter chamber, but there is no need for or no plans for fully automatic discharge, such as:
Fine chemicals in the chemical and metallurgical industries or filtration of metal mine slimes.
Refining of clay, pigment and dye products.
Liquid filtration in the food industry.
Environmental protection sludge dewatering (for municipal sewage and industrial wastewater).
1. What is the liquid that needs filtering?
2. What is the flow rate?
3. Temperature/PH value?
4. What are the main solid impurities that need to be filtered from the liquid? What is their content?
