Steel shot blasting machine is mainly used for steel plate, metal structural parts, machine tool bed, steel (cast iron) products, grids, construction machinery and bridge manufacturing. The product can apply strong shot blasting to the steel surface of the original state. The rust layer and the oxide scale on the rust layer make it obtain a uniform metallic luster, so as to improve the quality of the steel coating and its anti-corrosion effect. With the increase in the country's penalties for environmental pollution, acid cleaning has gradually been eliminated in the market, and steel shot blasting opportunities have been applied in more and more industries.
Features
The shot blasting chamber of the steel shot blasting machine and the layout of the shot blasting device were determined after computer simulation of three-dimensional dynamic ejection.
Uses H400 high throwing speed direct-attached cantilever centrifugal blasting device.
The shot blasting chamber body is welded to a box structure with 8mm thick steel plates. The strength is high without vibration. The internal use of cast steel Mn13 protective plate protection (single shift production life of 2-3 years), the use of blocking plate interface, effectively extending the life of the chamber, and can fully use the rebound of the projectile to form a second cleaning.
The front and rear seal chambers are equipped with 8-leaf spring seal V-shaped device, which can effectively prevent the shot splashing and reduce the wear and scratch of the seals on the components. The rest of the seal layers are sealed with high abrasion resistant rubber sheets.
In order to reduce the friction on the bottom hopper during the dropping of the pellets, there are buffer angles on the hopper.
In order to prevent the workpiece feeding from being misaligned during operation, a stop plate is formed at both ends of the roller table. The number of shot blasters can be determined based on the size of the workpiece, which reduces unnecessary energy waste and at the same time reduces unnecessary damage to the equipment.
The pellet supply system uses a special pneumatic control for the pill gate valve and photoelectric detection of the workpiece to prevent the projectile from throwing. The cylinder gate valve used by our company is a compact and lightweight cylinder without a base or an ear seat, which is more stable and reliable than a conventional seated cylinder, and it is easy and quick to maintain.
The dust removal system adopts three-stage pulse filter cartridge dust collector + cyclone body + settlement chamber, with excellent dust removal effect.
Because the workpiece is conveyed by the tool, the roller conveyor drive system uses bidirectional transmission.
Anti-reversal hoist adopts double insurance design: First, the transmission head wheel adopts a ratchet pawl mechanism to prevent reverse rotation, and second, the transmission motor uses a brake motor to prevent reverse rotation. At the same time, there is a lost rotation detection alarm device at the passive wheel.
Separator full screen curtain flow curtain design: variable pitch separator adopts dual-cylinder plus rotation resistance level meter control, according to the situation of the projectile automatically adjust the flow screen, to achieve the effect of full curtain curtain. This technology is unique to our company.
Projectile automatic replenishment device: There is an up-down material level meter in the silo at the top of the cleaning chamber to automatically detect the amount of projectiles. The lower part of the hoisting machine is equipped with a make-up bucket and a pneumatic gate, and together with the level gauge in the upper bunker, the supplement pill is controlled, and the fill-up bucket is provided with a material level meter to perform the pilling alarm.
The dust removal system adopts pulse reverse blow vertical filter cartridge dust collector, which is more effective than traditional bag-type and traditional oblique insertion filter cartridges. It is more convenient and quick to replace the filter cartridge with vertical arrangement (open the access door), overcome The oblique plug-in arrangement is difficult to maintain and the dust of the upper filter cartridge falls to the lower filter cartridge, resulting in an undesirable effect of dust removal.
