Q69 Roller Conveyor Shot Blasting Machine For Steel Plate and Steel Structures
Q6922 shot blasting machine is a specially designed machine used in the surface cleaning for various jobs. It can realize the shot blasting automatically.
2 Components and function
Q6922 shot blasting machine consists of roller conveyor system, blasting system, abrasive circulation system (separator, bucket elevator, screw conveyor), dust collection system, and electric control system. The surface finish level is Sa2.5.
2.1 Conveyor system
It consists of loading and unloading rollers, chamber rollers, connecting rollers.
● Rollers in the blasting cabinet are protected by special alloy jacket with lifetime over 4,000 hours.
● Conveyor system is driven by motors with inverter. Rollers can be controlled manually and automatically.
● Step-less speed is available. Roller conveyor could move in step with the whole machine or move faster.
2.2 Shot blasting system
Shot blasting system consists of auxiliary chambers, blasting chamber and shot blasting machine assembly. The abrasive media like the steel shots, grits are applied on the metal surface driven by the centrifugal force from the blades. Workpieces will be de-rusted, cleaned and roughened in blasting system to reach customer’s finishing level.
2.2.1 Auxiliary chamber
There are 5-7 layers of wear-resisting rubber curtain in it. The suspension type makes the exchange and access easier. The seal ability is excellent. No dust would be leaked out because of the negative pressure formed by the dust collector fan.
2.2.2 Blasting chamber
In the blasting chamber, the wall is protected by SPMn13 material liner and 65Mn protective liner, which has high wear resistant performance. Chamber inside protection plate all adopt the high strength nut fixed and pressure on the inner of blasting chamber, easy tear open outfit replacement. Prolong service life, reduce the cost and reduce maintenance frequency. The steel abrasive fall down freely and collected by screw conveyor.
2.2.3 Shot blasting machine assembly
This machine has 10 sets of high speed & performance blast wheels. Material of blades, control cage and distributor is Cr20S high-chromium, which has long service life. The lifetime of blade is over 500 hours, and lifetime of impeller and control cage is over 2000 hours. All wear parts are the market most universal national standard parts.
2.3 Abrasive circulation system
The system includes following parts: hopper, abrasive control valves, screw conveyors, bucket elevator, separator.
2.3.1 Screw conveyor
Screw conveyor consists of cycloid needle wheel decelerator, screw axis, conveyor shell, bearing, etc. It is a
standard conveying device and an important part of abrasive circulating system. The screw blade is made of 16 Mn.
This unit is responsible for conveying the abrasive to the elevator. Screw conveyor located at the bottom of shot blasting chamber, the spiral blade welding in the drive shaft. Conveyor motor drives screw conveyor to send abrasive to discharge outlet, then the mixed abrasive will be conveyed to elevator bottom.
On both ends of the screw conveyor adopt triple seal protection. the abrasive and dust will drop to the clearance between end plate and bearing once leak out, will not enter the bearing. Screw conveyor shaft with sensors detecting unit can detect the working state.
