Learn In Detail About 3 Types Of Filter Press Technology
Types Of Filter Press Machine Available For Use
Let Us Learn About Its Mechanism-
Industries use a filter press machine to separate solids from liquids. The pressure filtration method separates the solids from liquids by pumping a slurry into the equipment that is dehydrated under pressure. The type and the volume of the slurry that needs to be dehydrated influence the design of the filter press machine. NMP manufactures a range of filter machines to suit your capacity and application needs for more economical and trouble-free dewatering.
When the slurry is put inside, the solids in the filter machine are equally distributed during the filling cycle. Solids form the ‘filter cake’ by building upon the filter cloth. Once the chambers of the filter machine are full, the filling cycle is completed. Also, the ‘filter cake’ formed on the filter cloth is ready to be released. Filter press machines that are higher in capacity use fast-action automatic plate shifters. The automatic plate shifters speed up the fill cycle time. Some filter machines are specifically designed to operate for 24 hours in a harsh environment continuously. Such specifically designed machines are used in chemical manufacturing plants or mining industries.
A filter press machine can be built as per any industry’s needs and wants. It can be built in small, lab-scale 150mm presses to those with higher capacities. Higher capacity filter plates can go up to 1500-2000mm. It is used in various industries such as municipal plants, steel mills, mining, and power generation. One can also use filter press machine in food and beverage processing, chemical manufacturing, and cement and asphalt production. The configuration of a filter press machine is dependent on various factors, such as the longevity of the filter cloth material and the requirement of cake dryness. It also depends on the cycle time of filtration. Industries use filter machines to produce better quality goods.
Let Us Discuss Three Types Of Filter Press
Semi-Auto Filter Press Machine –
The operator activates each main control panel sequence step in a semi-auto filter machine. All the valves of the semi-auto machine are opened and closed with the help of manual help. However, some of the processes of the machine are done by the machine. The electro-mechanical plate shifting device is used in a semi-automatic filter machine configuration. The design of the filter machine provides us with the following advantages –
Dispensation of assemblies and complex designs makes it a more economical alternative.
The intelligent working principle of two-hand operation provides a more simplified machine operation. The semi-auto machine also comes with an emergency stop button.
The design of the machine is done in a way that will help any industry save space.
NMP will help you customize your semi-auto filter machine so that any industry can adapt to its different process requirements and their specific needs.
The semi-auto filter machine provides maximum flexibility and a high degree of configuration.
It comes with a compact and robust design to provide a more reliable and flawless filtration operation.
A semi-auto filter press machine comprises a plate shifter, drip tray, hydraulic cylinder, electric panel without PLC, and hydraulic power pack. It has applications in dewaxing, marble, ceramic, granite, pigments, dry precipitates, bentonite, and gypsum. The semi-auto filter machine is also used in sludge produced from galvanizing plants composed of aluminium, copper, chromium, nickel, cadmium, etc.
Manual Filter Press
A manual filter machine, an intermittent pressure filter, is utilized to separate solids and liquids of various suspending liquids. Industries that are small-scale and require low filter pressure can effectively utilize a manual filter machine. In this machine, the closing of filter plates and discharging cakes are done manually. This filter machine is very easy to operate, has a low operational cost, and has high filtration efficiency. When used in a laboratory, it is used as a testing machine with a small input quantity. Industries such as chemical, pharmacy, coal washing, metallurgy, and coal washing use manual filter machines when they need excellent filtration results.
When the process of filtration begins in the manual filter machine, each filter chamber of the machine is filled with slurry. The slurry is pushed inside by using the thrust plate's feeding port present under the feeding pump's impetus. The filter cloth, also known as the filter medium, holds on to the particles present in the filter chamber. The particles form into filter cake while the filtrate is drained out using the fluid channel or the water nozzle. If filter cake washing is needed, inject wash liquid using the washing port of the thrust plate. A manual filter machine has the following features –
It has a less filtration area.
It provides high functionality.
It gives excellent performance.Drip Tray
It is very efficient and economical.
It is very easy to operate.
It also has a rustproof body.
Membrane Filter Press
The membrane technology used in the membrane filter machine has a great effect on the dryness of the solid. The carrier body is attached to a flexible, impermeable membrane that compresses the cake in the chamber after completing the feeding process. The benefit of the extremely high degree of dewatering is provided by membrane technology. In addition, the cycle time of the filtration is reduced by an average of fifty per cent. The reduction in the filtration cycle time is dependent on the suspension through the membrane filtration.
A membrane filter machine gives a firm the following advantages –
It gives high productivity by reducing the washing and filtration cycle.
It provides less moisture in the filter cake.
Provides high elasticity of membrane.
It consumes less power.
It also requires minimal maintenance requirements.
It can squeeze pressure up to 16 bars.
A firm chooses filter press machines according to its needs and capacity. Every Membrane filter plate comes with its benefits. NMP will not only customize your filter machine as per your industry but will also help in installation and other assistance required.
The filter press machine is the equipment used for the separation method to separate solid and liquid. Filter press machine working consumes low energy, low to no human resources required, and high separation effectiveness of liquid filtering out, making it extensively used dewatering technology. Filter press is a widely used dewatering technology in papermaking, pharmaceuticals, food and beverage industries, mining operations, chemical industries, mills, marble, and stone cutting.
The separation of solids and liquids is done using a filter press machine. The pressure filtration process is done to divide solids/liquids. A slurry is pushed inside a filter press machine and is dehydrated when subjected to extreme pressure. Filter press machines are manufactured based on the volume and the slurry that needs to be dehydrated.
A filter press machine (also known as a Plate-and-Frame Filter press) illustrates the type of filters that evolved in the 1800s. Generally, the type of filter press used today is commonly known as "Chamber filter press," "Membrane filter press," or "Membrane plate filter." Many industries, such as the food, chemical, or pharmaceutical industries, make goods from liquid-solid suspensions or slurries. Solids and liquids are separated in a Filter Press Machine so that the good part of the mixture can be processed, packaged, or delivered.
