7. Engineering plastic cyclone spraying room
1) Working principle:
Under the suction action of the fan, negative pressure is formed in the powder spraying room to prevent the powder from overflowing outside the powder spraying room. After the powder is filtered by the filter element, the clean air is discharged, and the powder falls in the powder spraying room. Most of the powder enters the large cyclone tube, and then is pumped by the powder pumping system to the large powder bucket and circulated to the spray gun. The recovery system is equipped with pulses. The back-blowing automatic cleaning function, through the pulse controller, opens the pulse valve regularly, opens the compressed air in the air bag, and blows off the powder on the filter element to ensure that the filter element has sufficient ventilation at any time. The large cyclone recovery system enters the filter element with very little powder , It can ensure the continuous good recovery effect. The indoor exhaust system is adopted, and there is no secondary pollution at the air outlet of the fan.
2) Features of Cyclone Recovery Structure
The recovery cabinet is mainly divided into six parts, namely: spray booth exhaust pipe, primary cyclone cabinet, secondary pulse filter cabinet, fan exhaust/exhaust pipe, fan system, and electric control cabinet.
A. The exhaust pipe of the spraying chamber is the exhaust pipe connecting the powder spraying chamber and the recovery equipment. The powder-containing gas enters the recovery equipment from the spraying chamber through the pipeline for recovery processing. It adopts flange connection structure, sealed and welded by δ1.5mm steel plate, and the exterior is sprayed with plastic or paint.
B. The first-level cyclone cabinet is a large cyclone powder recovery processing system, with an all-steel structure design and an overall plastic spray treatment. The middle part is equipped with a cyclone tube; the upper part is a cyclone box with multiple inspection and cleaning windows, equipped with an internal powder self-cleaning device; the lower part is a first-level powder recovery box, which is connected by a lock, which is convenient for disassembly and assembly. The materials used are: 80×80 square pass, angle steel, δ1~1.5mm steel plate, etc.
C. The secondary pulse filter cabinet is a pulse back-blowing filter element powder recovery processing system, all-steel structure design, and overall spray treatment. The upper part is a pulse box, equipped with a pulse gas tank, 12 sets of pulse valves and a solenoid valve, as well as related circuits and gas circuit structures; the middle part is a filter box with 24 sets of rotary wing filter elements built in, with excellent filtering performance and long service life; The bottom is a secondary powder recovery box with a side-opening door structure design, which is easy to use. The materials used are: 40×40 square pass, angle steel, δ1~2mm steel plate and related accessories, etc.
D. The fan suction pipe is the suction pipe connecting the secondary pulse filter cabinet and the fan system. The clean air filtered by the filter element enters the fan system through the pipe. It adopts flange connection structure, sealed and welded with δ1.5mm steel plate, and the surface is sprayed with plastic or paint.
E. The fan system is composed of a 4-72 large centrifugal fan with a power of 37.0KW and an air volume of 23,000 cubic meters per hour. It is equipped with a fan silencer system, and the fan is controlled in a star to triangle shape.
F. The electric control cabinet is the control center of the Cyclone II powder recovery cabinet. The Cyclone II powder recovery controller uses a microcomputer chip for automatic control, program flow instructions, and uses famous brand electronic control components to automatically control fans and pulses and cleanup. And other functions.
