Sintered filter is a kind of filter which is sintered at high temperature by granular glass, quartz, ceramic, metal or plastic, and has micropores. Among them, the most commonly used is the glass filter. Its bottom is a porous sheet sintered with glass sand at about 873K, so it is also called a glass sand filter. There are two types: crucible type and funnel type.

Sintered filter washing and use

The glass filter is used with the suction filter bottle. For example, the crucible filter can be connected to the suction filter bottle through a special rubber seat, and the operation is the same as the vacuum filtration. The new filter should be pickled, suction filtered, washed with water, suction filtered, air-dried or dried before use. After the filter is used, it should be cleaned in time, and the precipitate should be poured out as much as possible, and then soaked with an appropriate detergent (which can dissolve or decompose the precipitate). Do not wash with decontamination powder, and do not scratch the filter with hard objects.

This type of filter is not suitable for filtering relatively concentrated alkaline solutions, hot concentrated phosphoric acid and hydrofluoric acid solutions (which will corrode glass), and it is also not suitable for filtering slurry precipitates (which will block the pores of the sand core), and insoluble precipitates (due to the precipitation cannot be cleaned. , such as silica). In order to prevent cracking and filter shedding, heating and cooling should be carried out slowly. After drying, it should be cooled down to warm in the oven before taking it out.

Sintered filter features

1. High filtration accuracy, stable chemical properties and corrosion resistance;

2. Good compressive strength, back-flushing regeneration, and long service life;

3. It is non-toxic to human body and does not pollute the filter medium;

4. Filtration precision: 3---5um;

5. Maximum working temperature: ≤80℃;

7. The surface area of the sintered filter is large, that is, the effective filtering area is large.

Categories are divided into: water filter, precision filter, air filter, oil filter element, diesel filter element, oil filter machine, oil filter truck, mobile oil filter truck, plate filter, filter disc, stainless steel filter, dust filter bag Wait

Used in petroleum, chemical, textile, metallurgy, electronics and atomic energy industries, it has the functions of filtration, dust collection, gas diffusion, flow evaporation, catalytic reaction, electrolysis, noise reduction, damping, fire resistance and sweat cooling.
