Hydraulic filter press are all simple designed filter press with reduced dimensions, the action of plate pack open and close is designed to be driven by hydraulic system. And the filter actions, plate pack open as well as the process valves are controlled by manual operation.
Automatic filter press are filter press that designed for a wide range application, allowing customization to suit particular processes and clients’ requirements. All action of the filter as well as the process flow can be controlled by PLC program, and carried out by the corresponding automation mechanical design.
Quick operation filter press are filter press that upgraded on basis of normal automatic filter. It allows the plates to be open group by group which considerably reduce the cake discharge time and increase the production per unit area of the filter. Such kind of filters are special developed for large throughput, high filtration ability products such as mining concentrates and tailings.
Plunger feeding pump is a volumetric pump that can provide a feeding pressure of up to 2Mpa. Its flow rate can automatically decrease with the increase of feeding pressure, making it particularly suitable for high viscosity, fine particle or high organic matter content slurry such as kaolin, ball clay and municipal wastewater.
Centrifugal feeding pump has a large flow rate and stable linear, it can better adapt to the characteristics of the filter press feeding process when used in conjunction with a frequency converter. It is suitable for easily filtered slurry such as concentrate and tailings dewatering, industrial wastewater filtration and hyrometallurgy industries.
AODD feeding Pump is easy to operate and maintain because it is driven by compressed air instead of motor, and it has multiple material options, which makes it suitable for either food and chemical industry or various types of wastewater. It is a good optional choice for feeding small and medium-sized filter press.
When the membrane filter press requires a squeezing pressure of more than 10 bar, using water as the squeezing medium is the most economical method. At this time, a squeezing pump is needed, vertical multi-stage centrifugal pump is compact in structure, stable in performance and easy to maintain, making it the most commonly used squeezing pump choice.
In order to regenerate the filter press cloth, the cloth washing system requires high-pressure water of 4Mpa or even 5Mpa. Mechanical piston pump is very suitable to be used as the cloth washing pump thanks to its simple structure, high efficiency and energy-saving character.
The washing of filter cake does not require high pressure, but requires a continuous and stable flow rate. Centrifugal chemical pumps have good corrosion resistance and high temperature resistance, and can meet the requirements of various cake washing conditions.
Belt conveyor is designed for big loading capacity, can be used for non corrosive filter cake with high specific gravity and relative dryness.
When the filter press cake has high moisture and viscosity, it may slip on rubber belt and reduce the conveying efficiency, while using a screw conveyor can effectively solve this problem which can rely on its spiral structure to forcibly push the filter cake and achieve the conveying purpose.
Double shaft filter cake crusher has a small footprint, high strength, and strong wear resistance. It can quickly cut the filter press cake into 40~50mm to make it convenient for long-distance transportation or suitable for backend equipment such as granulator or dryer.
When the slurry coming into filter press is highly abrasive, we will choose a pinch valve as the feeding valve; When the slurry is highly corrosive, ball valve performs better thanks to its good sealing design; And when the media in the pipeline is filtrate, clean water or compressed air, we prefer to use a butterfly valve to achieve cost reduction.
Pressure transmitter is used to provide feedback on pipeline pressure in order to control it within the setted range; Flowmeters are used to measure and record the flow rate of pipeline media; While load cell is used to measure the weight of the filter cake in order to determine the feeding degree of the filter press.
In order to meet the different requirements of end users, we can also customize various front-end and back-end equipment to cooperate with the operation of the filter press system.
