This QGW series of shot blasting machine is used to clean and remove the oxide coating, welding slag on the inner and outer walls of steel pipes,tubes. After the shot blasting,the pipe or tubes can appear the metallic sheen, strengthen the surface. This kind of shot blasting machine applies in the industries of petroleum, chemical, steel, city group heating and group drainage ect.
1. The impeller head is composed of blast wheel.the structure is simple and durable.
2. BE type segregator is very efficient and it can protect blast wheel.
3. The bag dust filter can greatly reduce air pollution and improve the work environment.
4. Abrasion resistant rubber belt can lighten the collision of work pieces, and lower the noise.
5. This machine is controlled by PLC.
The operation is easy and reliable.
The shot blasting machine for inner wall is designed by qingdao friend machinery co.ltd. It is composed of front and back sealed chamber controllled by pneumatic turning, spray gun and gun control device , gun- carrying car, variable frequency speed regulation walking system, steel pipe rotating system, steel pipe tightening system, automatic loading and unloading system, shot recovery system by wind force, sand hopper, sandblasting tank, winnowing separator, dedusting system, pneumatic system, compressed air system and electric control system.
The shot blasting machine can automatically load or unload steel pipe.It can blast shot automatally to the inner surface of steel pipe.
First, open the door of reveral sealed chamber.The automatic loading mechanism can automatically put the steel tube from the storage rack into the working position. The tightening device will hold the steel pipe when it is into the exact position, the sealed chamber is reversed, the steel pipe will start rotating, gun- carrying car will drag the gun and the inner wall of steel pipe will be sprayed.Our dedusting system with large air volume can recycle the shots and collect the dust in the steel pipe by wind force.When the cleaning is finished,the valves of shot supplying and blasting will be closed. The shot blasting system will be out of the pipe cleaned up. The sealed chamber will move outward.The loading system will automatically pull steel tube out. The steel pipe will roll into the discharge platform automatically.This is one operating cycle.
Our shot blasting machine has compact structure and stable operation. This is new type of special shot blasting machine designed and developed by qingdao friend machinery machine co., LTD with accumulating years of experience in small steel pipe spray cleaning machine manufacturing.
