The metallic components like scrap, bales, pig iron and foundry retains are stored in the hopper. The hopper shape is specially designed to enable bulky and irregular scrap pieces to be extracted without problem. Vibrating furnace charger is effective solutions to problems such as high labor cost, hazards operators faced in foundries, melting shops etc. Such a kind of automation allows foundry men to work at a safe distance thus preventing injuries arising out of molten metal splash. It also facilitates in rapid and quick charging of the furnace thereby allowing maximum utilization of the furnace, in addition to this, the damage to furnace lining is avoided which normally occurs in manual charging of the furnaces.
Vibratory
Furnace Charger consists of a vibrating feeder mounted on a moving
trolley with a storage hopper mounted above the feeder. Our company make
vibratory furnace chargers basically comprise of the following parts.
Vibrating Feeder suitable for delivering required capacity. Storage
hopper of required capacity. Moving carriage with driving arrangement.
Control panel for operating the system. Cable reeling Drum / Cable Drag
Chain.
The charging car on the vibrating furnace charger
comprises a discharge chute with vibratory feeder for the metallic
components and is hopper all mounted on the traveling framework with
drive gear. The discharge snout is inclined and formed of a rounded
trough to bring about a good charge distribution and enable irregular or
bulky pieces of scrap or returns to be discharged. The feeder is driven
by unbalanced motors. The vibration frequency can be altered by an A.
C. Inverter, thereby regulating the feed velocity and also influencing
the noise emission. The batch hopper as well as the charging feeder is
built in sandwich construction which reduces the noise generated by
contact between the charge materials and the hopper walls or feeder
deck. However, this does not eliminate the noise produced by contact
between the charge pieces themselves.
Vibratory Furnace Charger Operating Principle
The required amount of
scrap metal is loaded into the storage hopper at the loading point. The
trolley then carries the vibrating feeder along with the storage hopper
to the furnace charging point. Here, the vibrating feeder is energized
and the material is effectively discharged into the furnace as per the
required capacity. As the metal is melted down, fresh batch of metal can
be fed into the furnace thereby keeping the furnace full. The capacity
of the vibrating feeder can be varied by varying the amplitude of
variations. The amplitude of vibrations can be varied by adjusting the
position of centrifugal weights or by using a variable frequency drive
(optional). A control panel specially designed to suit individual client
requirement depending on the sequence of operations required is
provided.
Advantages for Using A Vibrating Furnace Charger
- Very fast as compared to manual charging of furnace thereby enabling optimum use of the melting system.
- Extremely controlled charging of material into the furnace.
- Prevents damage to the furnace lining since the material is properly guided into the furnace so as to avoid the material from hitting the furnace walls.
- No direct exposure of manpower to the furnace thereby preventing dangerous accidents due to metal splash (since the operator can carry out the operations at a very safe distance.
- Minimum heat loss of the furnace since the charging process can be maintained continuously at the required rate.
