Steel Plate Roller Conveyor Type Shot Blasting Machine/H beam blasting equipment
|Steel Plate Roller Conveyor Type Shot Blasting Machine/H beam blasting equipment|
The main difference of this shot blasting machine to others offered in the marketplace is the angled arrangement of the shot blast wheels on the top of the machine. This arrangement reduces the build up of abrasive on the sections of longer profiles.
By using this method a significantly larger percentage of the blasting energy is used on the main task, i.e. de-rusting and scale removal from sheet metal and profiles, and avoids creating mass piles of abrasive.
In practice, the HD roller conveyor machine with angled wheels blasts between 5 and 20% quicker than a roller conveyor with shot blast wheels that are installed straight. ANTAI roller conveyors are used where high throughfeed speeds and longer maintenance intervals are necessary.
With these features, this machine is particularly useful for integration into fully automatic production lines. The HD roller conveyor range can be delivered with widths from 1,500 4,000mm. All of the machines in this range are suitable for shot blasting sheet metal as well as profiles.
main features of the wheel sand blasting machine
As for your strict requirements of thesteel structure sand blasting machine, the main features of our company’s design are stated as following:
1. At the front part of the shot-blast cabinet there is a photoelectric height-and-width-finding device (photoelectric switch is brought in from Japan), which provide basis for opening amount and time of blasting wheel gate and up-down height of rolling and sweeping device.
2. The placement of shot-blast chamber and blasting wheel is defined according to computer 3D dynamic shot-blast simulation. By blots the blasting wheel is linked to the connecting base fixed to the chamber ( do not regard the chamber as the installation base), which helps installation and disassembly of blasting wheel,meanwhile,asbestos cushion is placed to reduce shock.
3. Sand blasting machine adopts high efficiency blasting wheel (with curve plates) of America DISA technology, which can form double casting belts. This broadens striking area of shots and avoids to over-concentrative phenomenon of shots when blasting wheel with great casting capacity works, which can increase productivity and achieve the most satisfied results. The equipment can not work when the upper gate of blasting wheel is opened. 4, Shot-blast chamber is a box structure welded with 10mm thick steel sheet. The high strength can avoid vibration. The inner is protected by wear-resisting Mn13 rolling guard boards which adopts spigot connection that can extend service life of the chamber and take full use of shots’ rebounding to form second cleaning.
5, Roller table in chamber is made by process and heat treatment of high Cr and Mo special iron protective shell, which extends service life and reduces repair rate. Bearing of two sides use maze-type guard to stop aggression of dust and broken shots and enhance working life of the bearing.
6, The upper and lower part of entry and exit of workpeices is sealed up by special wear-resisting (each has 6 layers), which reduced splashing and overflowing of shots effectively.
7,Reverse-proof of elevator is designed with double safety:one is that the upper transmission wheel is made with ratchet wheel catch pawl; the other is transmission motor uses braked motor. At the same time, a warning device is placed near the passive wheel.
8, Full and flowing curtain design of separator: Separator is controlled by double cylinders and impeding level probe. They can adjust flowing curtains automatically according to the shots’ situation so as to achieve effect of full and flowing curtain.
9, Automatic shot-replenishing device: At the top of chamber there are the upper and lower feed level recorders in the store for automatic detection of shot capacity. Shot-replenishing hopper and pneumatic valve at the lower part of elevator accompany with the upper feed level recorders to control shot-replenishing together. The feed level recorder in shot-replenishing hopper is to warn shot-feeding.
10, High recycle rate of residual shots: at the rear part of shot blasting machine there is a recycling bolt, rolling brush (stiff brush) and high-pressure fan to remove the remain shot on the surface of workpieces.
11, Dedusting system uses whirlwind and filter cylinder type dust collector that can reach dedusting efficiency beyond 99.9%, which surely meet requirement of integrated emission standard of air pollutants. Two sets of dollies with recycling bag are put there at the lower part of dust collector so as to discharge dust. The height of dust-releasing pipe is more than or equal to 16m.
12,The overall noise of the equipment is less than or equal to 90 dB.
13,The whole line uses simulation screens and PLC which means working state and malfunction are simulated to show, each operating state are displayed in multiple pages and program switch is set up according to the type of workpieces. Main elements such as PLC, inverter and so on introduce OMORON products.
14,All steel structures in the line are blasting-cleaned and rust-removed before welded,and then be painted with primer.
