It is a batch filter press. It uses pressure as the filtration driving force. It achieves efficient solid-liquid separation for various industrial applications.

Structural Composition

The equipment consists of key components. The main parts are thrust plate, main girders, pressure plate, manual plate pulling system, machine base and electric control cabinet. Filter plates and filter frames are arranged in an alternating way. Filter cloth is clamped between each plate and frame. All these parts form closed filter chambers together. The filter chambers are the core for solid-liquid separation.

Working Principle

It follows a clear and simple working cycle. First, the compaction device presses the filter plates and frames tightly. It forms sealed filter chambers in this way. Second, the feed pump injects the suspension into the filter chambers with pressure. The liquid part passes through the filter cloth. It becomes filtrate after passing the cloth. The filtrate flows along the grooves on the filter plates. It then moves to the corner channels of the plates and frames and is discharged out. Solid particles in the suspension are blocked by the filter cloth. They accumulate on the cloth and form filter cakes. After the filtration step, workers can do washing and air drying operations if needed. Finally, the filter press is opened. The filter cakes are removed. The filter cloth is cleaned thoroughly. Then the equipment starts the next working cycle.

Technical Features

It has outstanding performance advantages for industrial use. It supports high-pressure filtration. Its filtration pressure can reach 0.6-2.0MPa normally. It can even reach a higher pressure for special demands. It has high filtration precision. The precision can be as low as several microns. The filter cakes it produces have low moisture content. It makes the subsequent treatment and transportation of filter cakes easier. The whole equipment has a sturdy and durable structure. It can adapt to long-term continuous operation in industrial sites.

Compaction Modes

It has three compaction modes to choose from. It meets different application needs and site conditions. Manual compaction: It uses a screw jack to push the pressure plate. It is suitable for small-scale and low-frequency use scenarios. Mechanical compaction: An electric motor with a reduction gearbox drives the pressure plate. It provides stable and moderate compaction force. Hydraulic compaction: A hydraulic station drives the pressure plate through hydraulic cylinder components. It has large compaction force and high automation level.

Application Fields

It is widely used in many industrial sectors. It is a necessary solid-liquid separation equipment for various industries. Chemical industry: It is used for the separation of reaction products. It also recovers catalysts in chemical production. Food industry: It is applied in starch production processes. It is also used for wine filtration and other food processing links. Pharmaceutical industry: It is used for the purification and separation of pharmaceutical raw materials and finished products. Coal, mining and metallurgy industries: It realizes the solid-liquid separation of tailings slurry and coal slime. It reduces environmental pollution and recycles useful resources.
