How It Works - Patent - Drum Decanting Unit - BJVP
Overview:
A typical BJVP DDU uses roller conveyors to feed and discharge the
drums or totes – one at a time – onto the drum-weighing platform.
The proper drum is selected and fed in sequence onto the platform
by the operator. The platform is mounted on compression load cells
that weigh the amount of each material and a tilting device is
included to ensure maximum product recovery and removal. In
addition, a suction lance and swivel arm are inserted into the drum
to withdraw liquid. The operator initiates production using the
Supervisory Control System which pulls and verifies the component
recipe and line up. The controller ensures the continuous addition
of the required recipe amount of each component through the lance.
When the set amount of material has been withdrawn from each drum,
the lance is removed, cleaned in a rinse tube and restored for the
next drum in sequence. A rinse tank equipped with a heating system
is included. It flushes the lance to remove any remaining material
for maximum product recovery and minimum waste or
cross-contamination. Additionally, each empty drum is rinsed with a
low viscosity component to minimize any residual material in the
drum or tote.
*BJVP has the patent of VP Drum Decanting Unit.

F&Q:
Q1: What can DDU do in process transporation?
A: BJVP Drum Decanting Unit (DDU) System can deant, rinse, weigh at
the end of the decating, lance can trace the liquid level.
Q2: What is VP Drum Decanting Unit?
A: VP Drum Decanting Units are a mechanized and automated tools to add
small volume additives into a blender. They are equipped with
conveyor belts, a drum weighing platform scale, a concentric lance
to both withdraw additive and rinse empty drums and a weighed,
heated, rinse tank to provide rinsing stock for the drums to the
blending kettles. By automating dosing, rinsing, and transferring
you can increase efficiency and safety with our Drum Decanting
Units.
Q3: Where can this pigging system be used?
A: BJVP pigging equipment can be widely used in petrochemical,
lubricant oil, additives, pharmaceutical industry and other
industry applications.
