Cast iron filter plates are suitable for filtering various high-temperature materials especially for temperature higher than 80-100 degree with high temperature resistance.

Cast Iron Filter Press Introduction

A cast iron filter press is a type of equipment used to separate solid materials from liquids. It is made of thrust plates, cast iron compression plates (manual compression, mechanical compression, or hydraulic compression), oil cylinder bodies, and main beams.

Cast iron filter plates can be used to filter materials that are very hot, at temperatures higher than 80 to 100 degrees. They can handle high temperatures.

Elements of Cast Iron Filter Press

Hydraulic compression: The hydraulic compression mechanism has a hydraulic station, oil cylinder, screw, and locking nut. When hydraulic pressure is applied, the manual valve is pushed to provide high-pressure oil to the hydraulic station through the gear pump. This causes the piston rod and screw rod to be pushed out, and the middle top plate to be pushed in, compressing the plate frame.
The filter part is made up of cast iron filter plates arranged on the main beam in a certain order, with filter cloth sandwiched between the plates. The cast iron filter plates and filter cloth are arranged in a pattern that looks like this: one filter plate, then the next one, then the next one, and so on. This creates several different filtering units.
Pulling part: The automatic pulling part is made up of a hydraulic motor, a robotic arm, a transmission mechanism, and a suspension device.

Cast Iron Filter Press Features

Cast iron filter presses can withstand high temperatures, which is different from regular filter presses. The filter plate is made using a precise casting process from high-quality cast iron or ductile iron. This material can resist high temperatures (up to 200°C), is strong, and can handle high pressure (filter pressure ≤ 0.6MPa). It also has a long lifespan (10 years and more). It is often used to separate solid from liquid in industries like petroleum, chemistry, metallurgy, oil, and ceramics.

Right now, there are two types of cast iron filter presses, depending on the plate type:

A plate and frame type cast iron filter press is used to… It takes up a lot of space and can only be unloaded by hand. This type of filter is better at catching tiny particles than recessed plate filter presses.
A recessed plate cast iron filter press is a type of filter that is used in industrial settings. The Recessed plate cast iron filter press is more practical than the plate and frame type. There are two types of plate pulling methods: manual and automatic. The automatic plate pulling type is more automated, which saves labor and improves production efficiency.

Cast Iron Filter Press Working Principle

All the filter plates are pressed between the movable head plate and the fixed tail plate. This creates a sealed filtering chamber around the adjacent filter plate. After the filter chambers are filled with pulp, the pressure filtration process begins. During this process, the slurry is separated from the pulp by the feed pump. The solid particles are left in the filter chamber because of a barrier made of filter cloth. The filtrate is discharged through the filter cloth along the drainage channel on the filter plate. If the filtrate is not discharged, the dewatering process is complete. At this point, you can stop working on the material and return the head plate to its original position.
