(B). Electrostatic spray equipment:
Dusting system is the core equipment for powder coating.
(1) duplex powder room size: <L> 5000mm × <W> 1400mm ×
<H> 2000mm, 1 units
(2) Recovery System: 6 Cartridge Recycling (upper and lower body,
Whirlpool production), a set of
(3) Manual spraying machine: 2 sets (ordered separately)
(4) the closed loop system: 1 set (whale births)
Structure: the upright plate of the powder room, the roof, using
δ1.2mm cold plate production. Chassis, legs Q235 material, overall
flat, smooth, beautiful, recycling clean up powder convenience, has
a lighting device, easy to observe the spray effect. The powder
room, the screws can be a whole demolition.
Principle: Dusting chamber is the spraying workpiece studio, powder
spray booth and powder recovery unit is turned on, dusting interior
causing a negative pressure region, so that part of the powder can
not be deposited onto the surface of the workpiece does not exo
negative in the dusting chamber under pressure into the powder
recovery device and recycled.
Recovery unit principle: the powder was not adsorbed by the
workpiece, recycling to reduce production costs. Also prevent
powder linen in pollution of the environment.
Completion of powder recovery filter device. The qualified
recycling powder to collect powder barrel, and then through the
sieve into the barrels with new powder for the powder mixed re-use.
The closed-loop system:
The the powder closed-loop system meets the need of the coating
equipment recycling powder recycling, recovery powder automatically
supply the re-use of automatic guns. Improve the recovered powder
utilization, reduce labor intensity. Venturi powder pump imitation
imports designed to make the closed loop system to smooth air
passage, the powder is not blocked, the recovery performance.
(C) Suspension conveyor:

The machine has less power consumption, low noise, smooth running,
easy to operate, safe to use and advantages.
Chains: conveyor chain to complete the run within the horizontal
and vertical planes.
Drive and tensioner: using a single drive, single hammer tensioner
Emergency stop switch: across the board a total of three emergency
stop switches were installed in the upper and lower parts, dusting
Curved track: all curved track 16 manganese steel making.
Temperature expansion joints: When the orbit through baking drying
tunnel, a set of temperature expansion joints. Maintain the proper
gap between the two rail track portion is heated to compensate for
VVVF: "Huifeng" conversion, 1 set
