The filtration chambers of the filter presses with frames consist of two types of filter plates: frame and filtrating. The frame defines a filtration chamber and it is closed on both sides by the adjacent filtration plates with drainage draining filtrate. The thickness of the frame plate determines the thickness of the filtration cake it usually ranges between 10 50 mm. After passing clothes installed on the filtration plates, the filtrate is drained by drainage to channels drilled inside the plate and it is discharged out of the filter press. The working pressure usually ranges between 6 15 bars.
Filter press cloth Selection is one of the important elements in filtration using filter press. Based on our years of experience and lab testing, we can make an expert recommendation to you. NMP offers a wide ranges of Woven, Non woven and felted synthetic cloth. Woven construction of multi and monofilament fabrics having different air permeability or pore sizes. Thermal treatment (calendaring) results in unique surface properties that enhance filtration performance and cake release characteristics. The range of synthetic materials used comprises PP, PA, PET, PE and other polymers. We also offer antistatic cloth. Fabrication and assembly of filter cloth plays an important role to the fabric design in achieving optimum performance. A precise fit assures highest performance. NMP filter fabrics have been designed to meet with all and specific conditions in the filter press. The choice of correct fabrics, their assembly and fabrication techniques are tuned to the requirements of different sludge, products and industries. Easy Cake release, ease-of cleaning, extended life-time, particle retention and service costs are basic requirements to be taken into consideration.
Pumps suitable for high flow rates. Ideal for high-speed filtration and for slurry pumping.
Air operated diapharm pump. It is the best pump for small filter press. It is work by pressurized air. Main advantage of this pump is no over feeding happened in filter press.
Displacement pumps suitable for pumping of non-abrasive substances, they can be regulated by a frequency converter.
The system shifts the individual plates, opens the filtration chambers and allows the emptying of the filter press. Automatic shifting replaces manual handling of the plates.
Benefits and fields of use:
Automatic plates shifting options:
Individually plate by plate gradual shifting of single plates until all the set is shifted. The process can be interrupted any time and the operator can remove possible impurities from the cloth.
Simultaneous shifting of several plates shifting is carried out by a stroke of the hydraulic cylinder during the filter press opening. The single plates are fixed to the steel plate connected with hydraulic cylinder at certain distances and when the steel plate moves, the particular groups of plates are shifted at once. The process is fully automatic.
The drip trays catch spills off the cloth, or washing water during the cloth washing and drain it to the collection trough. They are installed under the set of filtration plates.
Materials
The most frequent material is PP, the plates can also be made of stainless steel or other materials as requested.
Benefits and fields of use:
The dropping cake can be conveyed via the hopper to a conveyor, which usually transports the cake to a container.
Benefits and fields of use:
These hydraulic power units (HPUs) consist of a base power unit, low-pressure manifold, and a high-pressure manifold. The base power unit includes a hydraulic oil reservoir, an electric motor, and a low-pressure hydraulic pump. High-speed models also include a high-pressure pump driven by the same motor. The low-pressure pump supplies hydraulic fluid to the low pressure manifold for the operation of automatic hydraulicplateshifters, drip trays, cloth washers, and the main cylinder.
Electric hydraulics are controlled by the NMP Electric Hydraulic Control System (EHCS), which monitors the status of the system and provides an emergency stop push button, disconnect switch and touch screen control of the filter press hydraulics.
Our hydraulic filter press is equipped with all of the protections required by safety regulations, and the electrical system is built according to the strictest current standards. High pressure filtration produces a filter cake of low moisture content. The powerful and effective filter cloth washing system prevents clogging of the filter cloth. Unique plates shifting and shaking device provides convenient and safe cake discharge from the filter press. Heavy duty steel construction with twice epoxy coated for maximum chemical resistance. Filter plates are corrosion resistant 100% polypropylene. Complete manifold including air blow down feature to assure driest possible cake. Hydraulic oil system for automatic press opening and closure. Fully automatic filter press with variable volume plates chamber plates and membrane plate. Power saving, free trouble, low operation and maintenance cost.
The feed pump drives the suspension into the filter press and overcomes the filtration resistance of the filtration cloth and the forming cake in the filter press chambers.
The feed pump usually increases up to 6 15 bar, the flow is controlled by a pressure switch, or a frequency (FM). The type of pump and the material used depend on the character and properties of the pumped suspension.
