Hook Shot Blasting Machine for Gas Cylinder

Hook type shot blasting machine is hook type cleaning equipment, composed of shot blasting room, elevator, separator, screw conveyor, two shot blasting assembly, shot control system, hook walking track, hook system, rotation device, foundation, dust removal system and electrical control part.

Shot blasting cleaning room

Shot blasting cleaning room is composed of chamber shell and guard plate.The dust removal port is arranged on the rear side wall.The shell of shot blasting room is welded steel plate and section steel, which is a sealed and spacious operation space for shot blasting.Two sets of shot blasting assembly are installed on one side wall of the shot blasting room to ensure the complete shot blasting of the cleaned workpiece.The area directly ejected by the shot blasting device in the compartment is lined with ZGMn13 of thickness 12, and the other areas are protected with 65Mn plate.The guard plate is compressed with protective nut to facilitate disassembly and replacement when necessary.The lower part of the chamber is beveled with steel plates to form a funnel so that the projectile flows into a spiral conveyor at the bottom.

The steel plate is also covered with a guard plate for protection.Above the screw conveyor, there is a steel leakage board, the top of the leakage board and wear resistant rubber board.When in use, wear-resisting rubber plate should be spread in front of the shot blasting device to protect the steel leakage plate below and extend its service life.The standard configuration of this machine is manual opening and closing mode.The machine is designed to open the door, and the inner side of the door is covered with wear-resistant rubber guard plate, which is pressed with steel platen and hexagonal special nut.Foam rubber strips are pasted all around to seal the door effectively.The lower part is provided with a slot for receiving the pellets, which will bring a small part of the pellets out when opening the door into the body of the chamber, to prevent the pellets from falling to the ground and causing people to slip and get injured.

An oil cup is arranged on the door shaft of the gate to lubricate the bearings in the loose leaf of the gate regularly.

Shot blasting machine

Shot blasting device is mainly composed of impeller, blade, shot separating wheel, directional sleeve, housing, guard plate, spindle, shot feeding tube and other parts.

The cantilever centrifugal shot blasting apparatus used in this machine has the advantages of high efficiency, easy installation and maintenance, small space occupation and rotation.In the process of rapid rotation, the blade is fixed by centrifugal force without any fixed fixture.To remove the blades, just tap the outer end of the blades to remove them. It only takes 10-20 minutes to remove the eight blades.

In addition, this series of shot blasting machine can also be removed at the same time to check the abrasion of the shot parting wheel and directional sleeve.In addition, the main shaft of the shot blasting device is mounted on the housing, and the holes of the fixed spindle and the directional sleeve are processed in one time, thus reducing the friction of the parting wheel and squeezing the directional sleeve, and greatly improving the shot blasting efficiency.Directional set in use process, often should check the wear condition of the rectangle window, when the window after about 5 mm wear, after must turn around 5 mm (by impeller direction of rotation), when the window loss more than 15 mm, should be changed or radial scattering Angle of the projectile will increase in proportion, so that to speed up the guard plate wear and reduce the cleaning efficiency.

Room hoist

The bucket elevator is composed of cycloidal needle wheel reducer and machine base, upper and lower rollers, conveyor belt, hopper, closed barrel and tensioning device.

The lower feed port of the bucket elevator is connected with the spiral conveyor, and the upper discharge port is connected with the pellet sand separator.Hoist housing adopts welding structure, beautiful appearance, good rigidity.The access door is provided on the hoist housing to repair and replace the hopper.Open the door cover on the lower housing to repair the lower transmission and eliminate the blockage of the bottom projectile.During operation, the hopper fixed on the conveyor belt will pick up the pellets at the bottom of the elevator, then, driven by the elevator mechanical and electrical machine, the pellets will be lifted to the top of the elevator, and finally, by centrifugal gravity, the pellets will be fed into the pellets for sand separation. At the same time, the elevator is equipped with a set of tensioning device.

When the belt is slack for a period of time, the belt can be tightened by adjusting the adjustment bolts on both sides of the lifting machine.The adjustment range is 100mm, and the adjustment amount at both ends should be consistent.

Shot sand separator

The machine adopts advanced curtain sand separator.The separator consists of separator screw, roller screen, shot bin and so on.A feeding port is provided at the funnel of the pellet sand separator to supplement the equipment with new pellets.The pellet sand mixture flowing from the bucket elevator is spiraled from the separator to the roller screen.The drum screen is provided with internal and external screw plates.When working, the inner screw plate moves the large particles such as sand blocks to the slag discharge outlet.After sieving, the pellets, sand and dust mixture is pushed by the spiral sheet outside the roller sieve and evenly distributed along the full length of the separator. Then the pellets flow uniformly to the bottom of the separator in the state of flow curtain through the adjustment of the separator's heavy hammer.At this point, the separator fan through the separator exhaust holes.According to the principle of gravity air separation, the pellets and metal oxide scale fragments, broken pellets and dust are separated effectively. The large particle waste flows out from the overflow port of the separator pellets, while the small pellets and dust flow out from the waste outlet, and the pellets enter the pellet bin for circulation.

Hook system

By hook, reducer, friction wheel, electric hoist components and so on.This system completes the functions of hanging workpiece, lifting the workpiece, transporting the workpiece into the chamber, and making the workpiece rotate in the cleaning room under the drive of the rotation device.

Screw conveyor

The screw conveyor is located at the bottom of the shot blasting chamber, and is composed of the screw shaft, blade, and both ends of the shaft head.The blades are welded to the spiral shaft.The lower drum of the hoist is mounted on one end of the screw shaft near the hoist.The screw conveyor is driven by the cycloid needle wheel reducer at the lower part of the hoist.During operation, the screw conveyor transports the pellet sand mixture to the bottom of the hoist, and then the hoist lifts the upper part and disloads it into the separator for pellet sand separation.Spiral conveyor and elevator together constitute the collection and recovery system of the projectile.
