Product Overview


Description of vacuum rotary drum filter

Rotary vacuum filter drum consists of a drum rotating in a tub of liquid to be filtered.

The technique is well suited to liquid, and liquids with a high solid content, which could clog other forms of filter. The drum is pre-coated with a filter aid, After pre-coat has been applied, the liquid to be filtered is sent to the tub below the drum. The drum rotates through the liquid and the vacuum sucks liquid and solids onto the drum pre-coat surface, the liquid portion is "sucked" by the vacuum through the filter media to the internal portion of the drum, and the filtrate pumped away. The solids adhere to the outside of the drum, which then passes a knife, cutting off the solids and a small portion of the filter media to reveal a fresh media surface that will enter the liquid as the drum rotates. The knife advances automatically as the surface is removed.



 Working principle of vacuum rotary drum filter

The filtering surface vacuum drum filter through a continuous rotation of the drum, and connected to the drum room, the distribution of the rotating drum filter surface partition, when filtering surface operation to an area (suction), filtering operation can be performed.When it is transferred to another area (dry), can be carried out on the filter cake drying.Again to other area (washing, drying and discharging, filter cloth blanket), can be corresponding to the filter cake washing, secondary drying, and through the discharging device of filter cake to discharge.Such as filtering slurry viscosity big, need to washing of filter cloth, after discharge, by installing the filter on both sides of the nozzle to washing of filter cloth, filter and then on to the next cycle.Drum rotation time, the cycle again.Complete the filtration, drying, washing, drying, unloading and regeneration of filter cloth and so on.In different regions at the same time, mechanical operation of the work, and form a continuous filtration.

Areas of application

chemical products, minerals, fertilizers, pharmaceuticals, food and other fields

Using the features

1. Applied materials
2. High filtering efficiency
3. Easy control, strong adaptability
4. It can realize automatic continuous operation
5. Good corrosion resistance

The advantages and disadvantages

Rotary drum vacuum filter function automatic continuous operation, saving human;Filtering, good adaptability, can deal with viscosity and compressibility of filter cake and easy clogging of the filter cloth material;But by vacuum hot liquid or vapor pressure of volatile liquid limit, driving force is small, equipment cost is more expensive.
