SLEEVE FILTERS

 

WITH CLEANING

 

 

VIA LOW PRESSURE

 

CLEANING SYSTEM

         In the low pressure cleaned filter, we use a centrifugal fan, with automatically limited power, incorporated into the clean room. This fan takes the already filtered air and pushes it, against the flow.

sThis causes the particles to detach. We use a pressure of not more than 35 grs/cm² and exactly the airflow required to reach the desired effect.

         This airflow is different in function of the number of simultaneous sleevelines.

         The flow of cleaning air is distributed via a rotating arm, mechanically driven, attached to the fan and to the sleeves via leastic bands.

 

  

LOCATION OF THE ROOMS

       The low pressure filter consists of 3 rooms which are inter-connected.

First room (entry room)

       This part of the filter is where the airflow comes in, with the highest concentration of dust. In this entry point, we put a fixed separator via impact, to cause the heaviest particles to fall. Only the light particles will reach the sleeve area.

       Underneath this first separator, is the attack cone and corresponding suice, normally with a slope of not less than 70°, to avoid accumulation of materials.

 

Sleeves room

       In this rooms you can find the baskets and sleeves that are the core of the dust filtration system.

      The baskets consist of a galvanized iron mesh and protecting cover, in order to protect the edges of the sleeves.

      The sleeves are of the Snap Band type, made of perforated polyester with a density adapted to the necessity of the aspirated product.

      In this module of the filter we install the explosive releasers, calculated according to NFPA norms.

 

Cleaning room

      This room has the cleaning system that works with inverse airflow. (In this case via a fan).

      In addition, it is possible to enter here and to replace or inspect the sleeves without any tools; this also allows for periodic maintenance.

      This allows the operators to work in total security. The access to this room is via stairs with midway platform and railing.  

 

ADVANTAGES OF THE LOW PRESSURE CLEANING SYSTEM

 

No pressurized air required.

Always works with dry and clean air, which increases the lifespan of the sleeves.

No electronic elements; the complete system is mechanical.

The room in the cleaning room enables you the replaceor inspect the sleeves without the risks and without specific equipment.

It is the most efficient system, allowing to increase the speed of the air while reducing the total cost of the equipment.

For big airflows, the hopper functions as a decantation room for the bigger particles; only the small particles arrive to the sleeves.
