Hydraulic filter presses are widely used in industries that require separation of solids and liquids. This equipment uses a hydraulic system to apply pressure on the filter plates to separate the liquid from the solid. The hydraulic filter press operation involves several steps, including filling, filtration, and cake discharge. In this post, we will discuss the different parts of the hydraulic filter press and the operating principles involved.
The Parts of the Hydraulic Filter Press
The hydraulic filter press consists of several parts, including the filter plates, hydraulic system, and control panel. The filter plates are made of high-quality materials such as polypropylene, stainless steel, or cast iron. These plates are arranged in a stack and are held together by a hydraulic cylinder. The hydraulic system applies pressure to the cylinder, which then applies pressure on the filter plates. The control panel is used to control the hydraulic system and adjust the pressure, time, and other parameters involved in the hydraulic filter press operation.
Hydraulic Filter Press Operation
The hydraulic filter press operation involves the following steps:
1. Filling
The first step in the hydraulic filter press operation is filling the filter press with the slurry. The slurry is a mixture of solids and liquids that need to be separated. The slurry is poured into the filter press, and the hydraulic system applies pressure to the filter plates to hold the slurry in place.
2. Filtration
Once the slurry is in place, the filtration process begins. The hydraulic system applies pressure to the filter plates, which pushes the slurry through the filter media. The filter media is a mesh or cloth that separates the solid from the liquid. As the slurry is pushed through the filter media, the solid particles are trapped, and the liquid passes through to the other side.
3. Cake Discharge
After the filtration process is complete, the solid particles are left on the filter media, forming a cake. The hydraulic system then applies pressure to the filter plates to remove the cake from the filter press. The cake is discharged from the press, and the process is ready to start again.
Advantages of Hydraulic Filter Press
Hydraulic filter presses offer several advantages over other types of filtration equipment. One of the significant benefits is that they can handle a wide range of slurry types and concentrations. They are also highly efficient, and the filtration process can be completed in a short amount of time. Hydraulic filter presses are also easy to operate, and the control panel allows for precise control of the process parameters.
