Filtration equipment (Nutsch-Filter)

Vacuum filters – suction filters are made of thick-walled polypropylene pipes, the inner part of which is divided by a perforated partition, with a filter cloth fixed on it (“spanbond”, non-woven polypropylene). In the upper part of the suspension is poured, the filtrate is collected at the bottom of the lower part. A vacuum is created under the partition using a vacuum pump connected to the suction filter through a receiver trap. The purpose of the receiver is to “smooth out” the pump pulsations and prevent the ingress of aggressive media into its mechanisms.

Filter presses – devices of periodic action, used to filter the sediment under the action of overpressure. These filters have a large filtering surface. The press filter consists of plates with grooved surfaces between which chambers are formed. The suspension enters the chambers through the channels, the filtrate passes through the filter septum, moves down the grooves of the corrugated surface and is discharged from the filter press along a common channel. The sediment in the chambers, if necessary, washed and dehydrated.

The net filter (other names – vacuum filter, capacitive filter) is used in various industries: mining, chemical, metallurgical, food and others.

• The simplicity and functionality of the design;
• Convenience in work use;
• Ability to work in aggressive environments in the temperature range of 0-100 ^оС.

Capacitive filter can be purchased in the range of modifications: from industrial, having filter area S = 0.7 m2, to laboratory with the same indicator S = 0.006 m2. Polypropylene is used as the main material for the production of filters. Filter cloth is supplied.

In order to prevent the filtrate from entering the vacuum pump, the suction filter is connected to the pump via a receiver.

At the request of the client, our company will manufacture vacuum filters of various modifications:

• equipped with a rotating mechanism (for suction filters with a filtration surface of more than 0.15 m2);
• having a mixing device;
• with a suspension receiver, made in a closed version (with a lid);
• on stand / on wheels;
• with variations of geometric (volume) parameters.
