The layout of the shot blasting chamber and the shot blasting device of the steel structure shot blasting machine is determined by computer three-dimensional dynamic shot simulation.
The steel structure shot blasting machine adopts QX30DS direct-connected cantilever centrifugal shot blaster with high projecting speed.
The shot blasting chamber body is welded with 8mm thick steel plates to form a box-shaped structure, which has high strength and does not generate vibration.
The interior is protected by cast steel Mn13 guard plate (single-shift production life is 2-3 years), and the guard plate is connected by seams, which effectively prolongs the service life of the chamber and can make full use of the rebound of projectiles to form secondary cleaning.
The front and rear sealing chambers adopt 8 loose-leaf springs to seal the V-shaped device, which can effectively prevent projectiles from splashing, and reduce the wear and scratch of the components on the seal. The remaining sealing layers are sealed with high wear-resistant rubber plates.
In order to reduce the friction on the bottom hopper during the falling of the shot, there are buffer angle steels on the hopper. In order to prevent the deviation of the workpiece when the material is not running, there are stoppers at both ends of the roller table. According to the size of the workpiece, the opening number of the blasting machine can be determined, which can reduce unnecessary energy waste and reduce unnecessary damage to the equipment.
The shot feeding system adopts a special air-controlled shot feeding gate valve and workpiece photoelectric detection to prevent empty throwing of projectiles. The cylinder gate valve used by our company is a small and light cylinder without base and ear seat, which is more stable, reliable and easy to maintain than the traditional cylinder with seat. The dust removal system adopts three-stage pulse filter cartridge dust collector + cyclone body + settling chamber with excellent dust removal effect. Since the workpiece is conveyed by the tooling roller conveyor, the drive system adopts two-way transmission.
The anti-reversal of the hoist adopts double insurance design: one is that the transmission head wheel adopts a ratchet pawl mechanism to prevent reverse, and the other is that the transmission motor adopts a brake motor to prevent reverse. At the same time, a lost-rotation detection and alarm device is provided at the passive wheel.
Separator full curtain flow curtain design: the variable pitch separator is controlled by double cylinders plus resistance rotary material level gauge, and the flow curtain is automatically adjusted according to the projectile situation to achieve the effect of full curtain flow curtain.
Projectile automatic replenishment device: The upper and lower material level gauges are installed in the silo on the top of the cleaning room to automatically detect the quantity of projectiles. The lower part of the hoist is equipped with a pill replenishment hopper and a pneumatic gate and the material level gauge in the upper silo to jointly control the pill replenishment.
The dust removal system adopts OL pulse back-blowing vertical filter cartridge dust collector, which is more effective than the traditional bag type and traditional oblique insert filter cartridges. The vertical arrangement is more convenient and quick to replace the filter cartridge (just open the maintenance door), overcome It eliminates the disadvantages of difficult maintenance of inclined insertion arrangement and unsatisfactory dust removal effect caused by dust falling from the upper filter cartridge to the lower filter cartridge.
