Automatic dispensing stations for chemicals and
dyestuffs are getting increasingly popular in dye houses. They can
reduce cost as well as increasing the reproducibility. With the chemical
dispensing systems, there is a facility for liquid dyestuffs and
chemicals to be exactly dosed in quantities that can be from 50 ml to
several hundred liters, along with the provision of transportation from
chemical room to each single apparatus. Compact design and the usage of
pumps, ensures freedom from space restrictions. This way a very simple
and cheap installation system is achieved. Two flowmeters are used to
measure the liquids volumetrically. The liquids are then carried to the
apparatus via pipe systems. The use of compressed air as a transporting
medium ensures minimal water consumption. Also, the feature of dosing
accuracy enables an overall reduction in the quantity of chemicals along
with gaining of additional quantities. Another significant role it plays
is to save workers from getting in touch with chemicals that are
injurious to health. It is on the stainless steel frames, that the
dispenser module is generally mounted. It includes a series of
accessories like a collector module for connecting the chemical tanks to
the pipeline system, a transport pump, a PLC controller, water
connection for rinsing etc.
The system can work as a standalone unit or can be fully integrated
with an existing network of EDP-system through interfaces to all control
systems and common recipe formulation.
The
Chemical dispensing system that is shown here in the diagram is that of
a fully automatic volumentric Dispense Unit. The machine works on the
principle of electro-magnetic flow measuring. This particular model has
a capacity to dispense all chemicals and dyestuff with a viscosity of
max 1000 mpas.
