An Innovative Invention - Automatic Filter Presses

The first and foremost type of filter press that is the Automatic filter press, differs widely from an old filter press machine. The basic structure, working principles, and process technology are similar to conventional press machines. In 1853 the British patent used the first form of filter press for procuring seed oil through various pressure cells.

The major advantages of a filter press are high-end filtration fleetness and a low amount of moisture content in filter cakes. There was a vast requirement for mass production in industries in mid of 20th century, and as a result, increasing recognition was given to the automation of filter press applications. Therefore new types of press filters were invented in Japan.

To meet the demands of growing industrial needs, researchers began working on developing an automatic filter press. After several failures in automatic cake discharge methods from a recessed plate filter press, they developed the world’s fully automatic type filter press machine. Also, over the last few years, there have been numerous advancements in types of filter press owing to automation needs.

The automatic filter press can expand high-end automation, enhancing the uninterrupted and smooth operation every time. Moreover, the high-speed automatic press filter machine yields empowered production in all the filter units. Undoubtedly, automatic press machines have been the most advanced product in all of their counterparts. Due to the unique requirements and needs of different organizations being in the hands of different industries, a tailor made filter press has been made, especially according to their respective application and purpose. Let’s discover the advantages and processes of an automatic press machine over conventional filter press machines in-depth to have a clear understanding of the working of an automatic filter press machine.

Understanding Automatic Filter Press

Filter presses are the charging house of the solid-liquid filtration world. They account for a significant segment of dewatering slurry. Two very crucial considerations when deciding on a filtration apparatus for a specific operation are the concept force for filtration and whether the filter will discharge filter cake consistently. There are two important components to a filter press:

  • A set of filter plates or components: Filter plates, over the years, have been made from metals and wood. But in today's world, a configured polymer is used to make filter plates. The core concept is that these plates are composed of a series of contained filter components when pushed together. Pressure is then delivered by a slurry pump where slurry passes into each of the chambers; retained filter cake accumulates in the chamber, and filtrate passes through a filtrate medium. The filter medium is generally a nonwoven cloth or a paper that is designed to withstand the motive force, which is trying to force the plate when extremely pressurized.
  • Plate Opening and closing (automated part): They are responsible for process control, moving from simple mechanisms to systems that analyze process conditions and respond. There are possibly many designs and combinations of filter press plates.

Various industries have made numerous advancements considering the future of automatic filter press machines. During a filtration process, the filter press chambers cannot be parallelly the same about the degree of cake formation. Advanced automatic press machines equipped with a diaphragm compression device have increased their fields of application and also comprise a sewage sludge treatment. Installing a fully automatic filter press can increase productivity while reducing the cost of the personnel because the operating time of an automatic press is 24 hours. Although a daily supervision check of the filter press is advisable as it involves personnel cost of about 2-3 hours per day which is definitely below the value of a manually handled filter press.

Automatic Filter Press Machines – Their Advantages

The automatic filter press not only provides high throughputs and efficient solid capture but must also operate continuously and smoothly in the hard environment, efficiently handling abrasive materials with minimal personnel requirement. The major benefits of an automatic filter press are as follows:

  • The automatic filter press is a fully advanced, programmed system that requires an individual start button to start the process.
  • It has a high level of automation and increased filtration time. Automatic filters can be rapidly cycled compared to their conventional types.
  • It reduces the person-hours to focus on other projects by eliminating the time spent scraping plates as it has an inbuilt automatic belt wash.
  • It has simple and economical filtration due to the high-end degree of dewatering, thereby shortening the cycle time.
  • The fully automatic execution of the dewatering equipment leads to a low personnel cost compared to the conventional filter presses.
  • The automatic filter press comes with a high level of security and protection as it is developed using the latest security technology and advancements.
  • The use of an automatic press produces more precise and accurate outcomes. Installing it, however, will reduce the potential of the occurrence of any type of error in the entire execution to a greater extent.
  • It utilizes few materials and reduces the overall operation cost, resulting in a highly efficient procedure.
  • As the dewatering equipment is completely automatic, which in turn reduces the chances of error, as well as less requirement of the labor resources, it will automatically lead to less energy requirement.

The benefits of an automatic filter press surpass conventional press machines. The superior design, high-end efficiency, and security result in a greater demand for the automatic press. NMP has a wide range of filter presses providing maximum flexibility between simple manual to fully automated filter press designs and can also be customized to your specific needs and requirements.

How Filter Presses Are Used In Various Industries?

In the mid 19th century in the United Kingdom, one used a rudimentary form of filter presses to extract vegetable oil from seeds. However, when in the 20th-century, major developments took place everywhere; scientists developed an automatic horizontal-type filter press. Since then, filter presses have gone through a lot of technological advancements and changes.
