III.Structural adjustment and adjustment
This machine is a high-performance V-belt conveyor sandblasting
cleaning equipment, in the process of
cleaning by motor drive worm gear and worm reducer, Towing V-belt
conveyor system to the work piece to clean room, and spraying by a all-around of 12 guns, making their
oxidation scales and dust’s away quickly, obtaining with certain roughness of
the bright surface, at the same time work piece is suffered from strong impact,
eliminated the stress of work piece, to avoid deformation. During the cleaning
process, falling mixture of dust scattered is collected directly by the set of
sand bucket, by the dust removal fan suck in suction separator, after the dust
separator was separated，abrasive sand goes to the storage tank，dust
is driven by fans, through the air duct pipe system, and with filters
precipitator dust, efficiency can reach 99%, after purification, the air
emissions into the air.
has the following several parts: Sandblasting main engine, Belt conveyor system,
Segregator, Dust removal system, Electrical Control System.
The master consists of three parts cleaning room, inlet room, and
A、Clean room is installed 12 spray guns, this space structure is
passed CAD test and actual verification, can achieve best to clean up the work
B、Cleaning room is semi-enclosed, equipped with steel and rubber
curtain shield to prevent abrasive flying, while room has some negative
pressure to prevent the escape of dust.
C、Cleaning room is equipped with rubber inside body, protect the
chamber wall plate from wear and tear, extending the service life; In the
cleaning of cone set sand bucket is equipped with the network, to block
sundries, protect the nozzle, easy to repair.
the application and maintenance
A、Cleaning room protection room and package cast nuts are wearing
parts. Must check the degree of wear and change in time, pay attention to install
guard plates lap joint, to prevent damage to the wall and endanger safety.
B、Cleaning room rubber curtain are wearing parts should be replaced
C、Must cut off the power for maintenance, listing alerts, non-powered
operation, and offenders will be could endanger life safety.
conveying system consists of v belt, master-slave shaft, cycloid reducer and
three-phase asynchronous motor, the system is stable and running speed can be
controlled by the frequency converter.
to the work piece cleaning efficiency, adjust the speed of the conveyor system;
from low speed to high speed slowly adjust, in order to achieve high quality
cleaning efficiency and good economic performance.
separator is a cyclone dust mixture was inhaled by back sand tube to the sand
separator, by sharing in formation of the cyclone, the walls of the abrasive to
jilt to the separator after free fall into the recycling in the store sandbox,
dust is inhalation of dust removal system, pure gases into the air after
purification treatment, become trapped particles of dust collection.
A、The above screw on regulator separator to change the starting
position within the cyclone separator to obtain optimum separation.
B、Separator outlet pipe connection with dust removal system,
guarantee the dust into the dust collection box.
