Analyze the filtration mode and characteristics of vacuum filter

Vacuum filter used in industrial production when the filter medium to separate the container with the upper and lower chamber, so that it can constitute a simple screening program. In the filter when the suspension to participate in the upper chamber, the pressure effect through the filter medium into the lower chamber to become our filtrate, so that the appearance of the filter medium will form a filter residue, that is, we often say that the filter cake. The formation of the filter cake is mainly due to the solid particles in the filtrate trapped in the filter medium appearance. After the formation of filter cake for the development of the filter has a very good help.
Filter by:
Vacuum filter in the earliest industrial production is mainly used for gravity filtration, after the manufacturers of innovative processing, is also used in the vacuum packaging industry. In the twentieth century, the drum vacuum filter was well used in the filtration of the connected operation. Today we are good to tell you about how the vacuum filter is used in industrial production.
In the use of vacuum filter when we used the filter there are three: filter layer filter; deep filter; sieve these three ways in the use of their own advantages, let us to specifically understand it:
Filter residue filter: mainly based on the retention of large solid particles, small particles with the filtrate through the filter medium, and then these small particles to form filter cake, trapped large solid particles, can be a good guarantee of the cleanliness of the filtrate. Common with a frame filter press.
Deep filtration: Filtration in this way when the filter medium is thick, the suspension contains less solid particles, in the filter when our solid particles are adsorbed in the channel, in order to obtain useful filtrate. Common with porous plastic tube screening filter.
Screening: This way with the above two kinds of no special, industrial production is the most common is the drum filter filter, can be a good way to remove impurities in the sewage.
The above is the use of vacuum filter on the use of knowledge, followed by the introduction of the three filter methods may feel no difference, in fact, only really skilled use of filter products before they can guess the difference.
