Shot blasting machine manufacturer:how to prevent corrosion inside the steel pipe shot blasting machine

technological process

Workpiece cleaning sequence:

The steel pipe is lifted by the crank arm and landed on the rotating idler of the rotating mobile vehicle (during the internal shot blasting) → the rotating mobile vehicle sends the steel pipe into the fixed shot blasting chamber and seals the front end of the steel pipe → the moving shot blasting chamber, seals the rear end of the steel pipe → the hydraulic shot blasting vehicle pushes the internal shot head into the steel pipe for shot blasting. After rust removal, all moving parts shall be reset.

Bullet circulation sequence:

Shot storage → flow control → belt shot feeding → shot cleaning → shot delivery to a fixed shot blasting room → back to shot delivery → screw conveyor → bucket elevator → shot slag separator → shot storage hopper (recycling).

Dust treatment sequence:

1. Shot blasting chamber dust → air volume control → inertia dust collector → bag dust collector → fan → discharge into the atmosphere.

2. Shot slag separator dust → air volume control → filter cartridge dust collector → fan → discharge into the atmosphere.

The steel pipe inner wall corrosion prevention production line selects the steel pipe inner wall shot blasting cleaning machine to remove the rust on the steel pipe inner wall, and uses the high-pressure airless liquid coating process to carry out the liquid coating corrosion prevention on the steel pipe inner wall, which is applicable to the liquid epoxy drag reduction coating and solvent-free coating of the steel pipe.

Shot blasting room

The shot blasting chamber is divided into mobile shot blasting chamber and fixed shot blasting chamber.

The sealing chamber is welded with profile steel frame and steel plate to ensure sufficient rigidity and strength.

In order to ensure the abrasion-resistant life of the shot blasting chamber, the fabric of the shot blasting chamber has the abrasion-resistant life of the shot blasting chamber SPMn13 rolled high manganese steel lining plate, with the lining plate life>25000 hours.

The shaft-mounted reducer drives the movable seal chamber, and the speed can be adjusted by frequency conversion. It can walk forward and backward, and the top of the steel pipe can be sealed.

The quick-change polyurethane sealing plate is set at the opening of the shot blasting chamber to seal both sides of the steel pipe to prevent shot splashing.

The steel pipe is positioned in the fixed shot blasting room and dust removal equipment to recover and purify the dust after shot blasting.

Shot blasting mobile trolley

Hydraulic inner wall shot blaster, strip equipment, ball thrower supporting roller, hydraulic pump station are installed on the mobile car, and the traveling speed of the mobile car is variable frequency speed regulation.

High-pressure closed hydraulic system of shot blasting machine

Shot blaster driven by hydraulic system such as hydraulic pump station and hydraulic motor.

The hydraulic pump station is installed on the shot blasting locomotive and connected with the hydraulic motor through the high-pressure oil pipe. The hydraulic motor drives the shot blasting machine to clean the shot blasting machine. German imported hydraulic plunger electromagnetic ratio high pressure pump REXROTH products. The pump station motor is 110kw, and the working pressure of 21 system is. 0Mpa.

Equipment with shot

Because the shot blaster moves the shot along the length of the steel pipe, the skill of moving the belt is used. The belt shot feeding equipment is installed on the hydraulic mobile truck, and the extension arm processed with special skills is selected as the support of the belt shot feeding equipment to continue the shot feeding.

Belt projectile retraction

The shot shot from the inner wall shot blaster enters the fixed shot blasting chamber through the tail of the steel pipe. The projectile is collected through the funnel and dropped on the recovery belt, and then transported to the elevator, separator and hopper for recycling through the belt.
