Product Description

Q69 roller conveyor shot blasting machines for surface cleaning
Product Description

Components and function
PHQ69 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.

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 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.

3 Auxiliary chamber
There are 5 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.

4  Blasting chamber
In the blasting chamber, the wall is protected by SPMn13 material 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 grilling floor of blasting chamber can let abrasive fall through it freely and collected by screw conveyor.

5  Shot blasting machine assembly
This machine has 4 sets of high speed & performance blast wheels. One blast wheel has eight blades. It takes 5 to 10 minutes to replace 8 pieces of blades. Material of blades, control cage and distributor is 18-20% high-chromium cast iron (USA: 5115G51150 Model), which has long service life. Generally speaking, lifetime of blade is over 500 hours, and lifetime of impeller and control cage is over 800 hours. All wear parts are the market most universal national standard parts.

6  Abrasive circulation system
The system includes following parts: hopper, abrasive flow pipe, abrasive control valves, screw conveyors, bucket elevator, separator.

7  Screw conveyor
Screw conveyor consists of cycloid needle wheel decelerator, screw axis, conveyor shell, bearing, etc. It is a standard transverse conveying device, an important part of abrasive circulating system. The screwing blade is made of 16Mn.
This unit is responsible for the abrasive delivered to the elevator. Screw conveyor located at the bottom of shot blasting chamber, the spiral blade welding in the drive shaft. Conveyor motor through cycloid speed reducer drive rotary screw conveyor, send abrasive to discharge outlet, then the mixed abrasive will be collected to elevator bottom.

On both ends of the screw conveyor adopts triple seal protection, plus labyrinth seal cover in the interior of the end plate, middle with oil seal protection, end plate external insulate bearing and end plate. Once the abrasive and dust out, will drop from the end plate and bearing clearance, will not enter the bearing
8  Bucket elevator
Housing of bucket elevator is welded of steel plate.
There is a checking door for maintenance and replacing buckets at the bottom of the housing.
The buckets are screwed to rubber belt which is stretched between two pulleys.
Belt material: Polyester.
Consists of cycloid needle wheel decelerator, upper and bottom barrel, belt, bucket and tensioning device, etc

In operation, the hopper fixed on the conveyor belt sweeps the abrasive on the bottom, and send abrasive to the top, then by way of gravity centrifugation blanking. Using polyester wire core special belt, high strength, high tensile properties. Pulley using squirrel cage structure, middle is slightly raised, each spokes are processed by machining chamfering. Both to improve the promotion of friction between the belt and pulley, avoiding the old-fashioned light
pulley slipping and sliding belt pulley on the injury, also reduces the lifting belt preload, extend the life; while avoiding scattered grit embed between the pulley and belt, affecting transmission.

Lifting capacity leaves 10% margin. Because the elevator blank by way of centrifugal gravity. Each time blanking, there will always be part of the abrasive down to the elevator, and therefore need appropriate to increase the lifting amount.
9  Separator
This machine uses most advanced full screen curtain air selection separator which includes selecting area, rotary screen drum, conveying screw, overfall sensor, abrasive stock bin and abrasive controlling valve. The abrasives mixture is conveyed into the separator screw via the elevator. Then the abrasive/sand mixture is carried out of the separator by the inner screw of the screening drum. The outer screw of the screening drum distributes the mixture along the separating are baffler of separator. Separating efficiency can reach 99.5%.

10  Dust removal system
The dust removal system consists of ducting system and filter cartridge dust collector. The emission standard can be lower 100 g/m³.We provide piping according to different machine type. Material is usually Q235
  Dust collector (Filtering cartridge type)
It is the final dust collecting system. Stable and easy operation, low noise, high efficiency and easy maintenance. This system for GBJ4-73 industrial "three wastes" emissions standards, the main fan power is 11kw, ventilation quantity is 12000m3/h, Pulse blowback dust removing, cartridge can be easily removed for cleaning then re-use.

11  Electric control system

The electrical control system for three-phase AC frequency 50 HZ voltage 380 V power distribution or customize.

The machine electrical system has the following features:
The blasting wheel, maintenance door, abrasive controller and abrasive circulation system are equipped with electric
interlock and self-locking system to ensure the reliable operation of the equipment and the safety of operators.
This system's blast wheel running conditions adopts the ammeter monitoring control, on the one hand, can through
the ammeter to protect blast wheel, on the other hand can monitor the blast of the empty cast, the phenomenon
such as jam, in order to adjust the equipment working state.
Pulse detector:
Pulse detector is installed in the screw spindle nose of abrasive separator, driven pulley spindle nose of elevator and
spindle nose of each screw conveyor.
Composition:  Proximity switches; Sensors semicircular iron.
