Overview

Plate frame laminated filter is a classic and efficient pressurized filtration device, widely used for its sturdy structure, large filtration area, and high solid content of filter cake. It consists of multiple hollow filter plates and solid filter frames that are alternately compressed under strong force, forming a series of independent filter units. This device is particularly suitable for filtering suspensions with high solid content and uneven particle size, and can form a dry filter cake for effective washing. With its reliable performance and wide adaptability, it is a fundamental and important solid-liquid separation choice in fields such as chemical, mining, metallurgy, and environmental sludge treatment.

Product Details

Plate frame stacked filterIt is a pressure filtration equipment with mature technology and strong processing capability. Its name comes directly from its core structure and working method: by alternately stacking multiple filter plates and filter frames, and applying huge pressure through hydraulic or mechanical clamping devices located on both sides of the crossbeam, they are tightly combined to form a series of sealed filter chambers inside the equipment.

The main components of the equipment include the tail plate, filter plate, filter frame, head plate, clamping device, and frame. The surface of the filter plate is designed with complex channel grooves and covered with filter cloth, which plays a role in supporting the filter cloth and guiding the filtrate to flow out; The filter frame is located between two filter plates, and its cavity constitutes the space for accommodating the filter cake. The corners above the filter plate and filter frame are both provided with through holes, which together form a complete feeding, washing, and exhaust channel when stacked.

Its working cycle usually includes four stages: compression, filtration, washing (if necessary), and unloading. The suspension to be filtered is pumped into the closed filtration chamber formed by high-pressure pumping through the feed pump. Under pressure, the liquid passes through the filter cloth, collects along the grooves on the filter plate, and is discharged from the outlet valve to become a clear filtrate; The solid particles are intercepted by the filter cloth and gradually accumulate in the cavity of the filter frame to form a filter cake. When the filter cake fills the filter frame or the pressure reaches the set value, the filtering stage ends. If the process requires, washing solution can be introduced to replace and wash the filter cake. Afterwards, compressed air can be introduced for cross flow drying to further reduce the moisture content of the filter cake.

After completing one cycle, release the clamping device and move each filter plate and frame in sequence. The filter cake falls off from the filter cloth due to its own weight, achieving unloading.

The main advantage of this type of equipment is its sturdy structure, which can withstand high filtration pressure; The filtering area can be flexibly increased or decreased according to the processing capacity; The formed filter cake has a high solid content and ideal washing effect. Therefore,Plate frame stacked filterIn situations with large processing capacity, high solid particle content, or requirements for filter cake dryness, such as chemical synthesis post-treatment, mineral concentrate dewatering, metal hydroxide sludge treatment, etc., it is always a practical and reliable choice.
