2. Airlock / Rotary Valve
•
The airlock is a Walinga 1210 drop thru airlock, built as a single assembly.
•
27 1/2” long X 23” wide.
•
The airlock will be placed under the primary separator and above the customer's
discharge option, which will be indicated on the piping layout / system design
drawings.
•
Discharge piping is 6” and
should be installed vertically with
a maximum of 20deg slope. This
ensures that dust will flow
through spouting using only
gravity.
•
The airlock operates off of an
electric motor and chain drive
and has to be placed in an easily
accessible location for service.
3. Secondary Receiver / Separator
•
Placed after the primary separator, the secondary separator operates the same
way as the primary. It's purpose is to further separate product from the air
stream.
•
It typically ships as two pieces that need to be assembled.
•
On the bottom of the secondary separator is a 6” outlet with a mounting plate
built into it. Below this will be a slide gate or a flap seal.
•
When equipped with a slide gate 6” discharge spouting will be required.
•
When equipped with a flap seal ensure there is enough room below to empty
the cone into an appropriate container
•
70” high X 19” diameter.
