As initial data, we take the customer’s requirements, European regulatory documents, inspect all sources of dust formation and make a preliminary calculation.
For calculation, the following data are taken: volume mass and product speed, number of dust collection points, length of horizontal pipe sections, height of vertical sections, number of bends, adapters and turns, resistance of the cyclone or filter.
In old aspiration systems, one system maintains 3-4 dust collection points, then a dust fan, which, passing dust through it, drives it to the cyclone. For large elevators, where it is necessary to dust more than 20 points, there are 5-6 such systems with cyclones. This is not convenient due to the large number of occupied space, maintenance, difficulties in collecting dust from different places. Dust fans require constant maintenance and cleaning to reduce the risk of explosion.
Offered by AGRO PROFF aspiration systems allow to assemble up to 20 or more dust collection points into one filter, which reduces further maintenance costs, reduces dust emissions to the atmosphere, and allows the return of cleaned warm air back to the workshop. The fan is placed after the filter and creates a vacuum in the entire system, including the filter, passing through itself purified air. Such a system is much more convenient and safer.
In our system the dust boxes, the diameters of pipes, rotations are precisely calculated, so that the product itself is not carried away with dust. We select the right filter, the fan of the desired pressure, taking into account the resistance of the entire line. In each section, control hatches are provided. Upon completion of the installation work, the flow rate in each section is measured and adjusted.
