Hydraulic filter press

Hydraulic filter presses Hydraulic presses are the type of filter press equipment currently available on the market in accordance with the pressure source of the filter plate, which of course belongs to the filter press. The pressure source of the hydraulic filter press is provided by the hydraulic pump of the device, so this is the source of its name. The liquid filter press is now used in all filter presses and it is the most widely used one.

Hydraulic Filter Press Principle The pressure system of a liquid filter press consists of a hydraulic station, a hydraulic chamber, and a controller. First of all, the hydraulic station of the hydraulic filter pressurizes the hydraulic oil in the station and presses into the tubing connected to the hydraulic chamber. The high-pressure hydraulic oil enters the forward chamber of the hydraulic chamber, so that the oil in the forward chamber is continuously increased, the piston is pushed, and the piston is pushed again. It is connected with the screw rod of the filter press filter plate and pushes the piston forward. It pushes the filter plate, which provides pressure for the filter chamber. When the pressure reaches the design upper limit, the control pressure gauge will automatically control the supply of the fuel station. jobs. In the filtration process of the filter press, when the pressure in the filter chamber is less than the pressure needed for the work, the control pressure gauge will automatically open the oil station, continue to provide oil for the hydraulic chamber, and continue to increase the pressure of the filter press. When the filter press needs to be retracted, the oil station injects oil into the receding chamber and moves the piston in the opposite direction, thereby pulling back the filter plate, and at the same time, the oil pressure in the forward chamber is returned to the oil station for recycling.

Advantages of Hydraulic Filter Presses The biggest advantage of hydraulic filter presses is that they can automatically maintain pressure, and the pressure is much greater than the manual and mechanical pressures. This ensures that the filter press can run better and is used more in each line. industry. In short, the hydraulic filter press has several advantages: the pressure of the hydraulic filter press can reach 1 MPa when filtering, and 25 MPa when pressing. This increases the filtration efficiency of the filter press and reduces the water content of the filter cake. The control pressure gauge automatically controls the opening and closing of the hydraulic oil, so that the hydraulic filter press can automatically maintain the pressure operation, ensuring a good start-up filtration function of the filter press, and making the performance of the filter press more stable. The hydraulic filter press can work normally in the environment between -5°C and 120°C, making the filter press more use in various complex and harsh environments, increasing the applicability of the filter press. In terms of energy conservation, hydraulic filter presses are more energy-efficient and reduce the use of filter presses.

The scope of use of the liquid filter press The hydraulic filter press is widely used in all walks of life. It is widely used in industries such as pharmaceutical manufacturing, chemical industry, bio-production, metallurgy, smelting, domestic industrial wastewater, and river governance. In particular, the use of sewage in the future will account for more than 40% of the filter press.
