The filter press is a steady and versatile “universal assistant” in the industrial world. From sewage treatment to chemical production, it can easily handle solid-liquid separation. It is simply an indispensable work partner! Today, let us unveil the mystery of the filter press and see how many “brothers and sisters” they have and what their “specialties” are.
Plate and frame filter press – the most traditional “big brother”If the filter press is a big family, then the plate and frame filter press is undoubtedly the “big brother” that has gone through wind and rain. It has been the “leader” in the field of solid-liquid separation since the origin of the filter press family. Its appearance is like a stacked “brick wall”, with filter plates and filter frames arranged alternately to form small “warehouses” specifically for loading those liquids that “need to be squeezed”.
Specialties: traditional, durable, and strong processing capacity. It is especially suitable for handling large volumes of sludge and suspensions with high solid content. In other words, it is particularly good at “heavy work” and can handle complex and difficult separation tasks single-handedly.
Disadvantages: It is a bit troublesome to operate, and it is not convenient to disassemble and clean. After all, when you are old, there are always some inflexible places.
Diaphragm filter press – the “modern” upstartAs the “younger generation” of the plate and frame filter press, the diaphragm filter press is a “modern talent” that should not be underestimated. Its structure is similar to that of the traditional filter press, but each filter plate is equipped with a “diaphragm”, which can be pressurized by the hydraulic system to further squeeze the already formed mud cake, so that the water can be discharged more cleanly.
Special skills: strong water removal ability and high mud cake degree. It is like a “high-efficiency pressure cooker” that can completely squeeze out the remaining water, and its efficiency is comparable to that of some high-pressure instant coffee machines!
Disadvantages: The price is more expensive than the traditional plate and frame filter press, and it may be a bit “overwhelmed” when handling large volumes of liquid.
Automated filter press – the gospel of “lazy people”For those “lazy people” who hate manual operation, the automated filter press is a magic weapon! Its core feature is “automatic control”, which can not only automatically adjust the filtration pressure and feed volume, but also automatically discharge the mud cake after the filtration is completed. You can sit in the office, drink coffee, press a button, and let it do the rest.
Special skills: Fully automatic operation, saving time and effort. It is like a “vending machine in the industrial world”. You just need to put in money (of course not literally), and it will do the rest in one go.
Disadvantages: Although it is convenient, it also means that once a fault occurs, you have to ask professional technicians to repair it, don’t think it can be solved as easily as adjusting the TV.
Chamber filter press-the practical school of “striving for strength”The frame filter press is a bit like the plate and frame filter press, but its filter frame is deeper and has a larger volume than the plate and frame. It can process more materials in a longer time and can operate stably in some harsh environments.
Special skills: When dealing with filtration tasks that require a large volume, the frame filter press is particularly powerful. It is the “powerful school” that “is not impatient and steady”.
Disadvantages: Slightly slower processing speed, not suitable for those high-pressure tasks with tight time limits.
