Advantages of Steel Structure Shot Blasting Machine
The steel is hoisted into the feeding roller table and sent to the closing shot blasting cleaning room by the roller table conveyor system. The impeller rotating at high speed is used to accelerate the steel wire shot (Abrasive) to the surface of the workpiece and impact the surface of the workpiece, scraping to remove the rust and dirt on the surface of the workpiece, and then use the roller brush, the collecting screw and the high-pressure blowpipe to clean the accumulated particles and floating dust on the surface of the workpiece, and then it is sent out of the purge chamber by the roller conveyor system to the delivery roller. Then transport it to the designated unloading rack via forklift or crane.
Features of Steel Structure Shot Blasting Machine
Workpiece detection device, effectively control the opening and stopping time of the shot blasting machine, avoid the emptying of the steel shot blaster, save energy, and improve the lives of the wearing parts such as the room guard plate and the shot blasting machine.
This machine is equipped with functions such as automatic fault detection and alarm, and automatic stop after the delay.
Dust removal system adopts high-efficiency filter drum dust collector, the dust emission is within 100mg / m3, and the workshop dust emission is within 10mg / m3, which greatly improves the worker’s operating environment.
The bearing protection at both ends of the elevator, separator, and screw conveyor adopts a labyrinth sealing device and a U-shaped boss structure. The separation screw and screw conveyor discharge ports are arranged at a distance from the end, and at the end of the screw Add reverse conveying blades.
The hoist adopts special polyester wire core hoist transmission belt, and the upper and lower reels of the hoist adopt chambered squirrel cage structure, which not only increases friction to avoid slipping, but also prevents scratching of the belt. Each power point of the Abrasive circulation system is provided with a fault alarm function.
The large nut fixed by our company adopts cast special iron nut, its structure and the contact surface of the protective plate are larger, and it is more effective to prevent the broken ring caused by the Abrasive entering the shell due to the loosening of the nut.
Abrasive cleaning: in order to meet the requirements of higher production efficiency, we use abrasive cleaning.
First-level cleaning: high-strength nylon roller brush + pill collecting screw; cleaning brush life ≥5400h
Secondary air blowing: high-pressure fan blows shots and blows dust inside and outside the cleaning chamber to ensure that there are no shots on the surface when the steel plate is cleaned out of the cleaning room.
The abrasive circulation purification system is composed of a circulation system and a separation and purification system. These two parts are further divided into a pill silo, a sliding tube, an abrasive controller, (shot blaster,) screw conveyor, a bucket elevator, a separator, etc. The system’s abrasive controller, screw conveyor, bucket elevator and pellet separator are interlocked in the electronic control system: the post-process does not work, and the pre-process cannot run, thus avoiding equipment failure due to abrasive blockage.
Roller drive adopts step-less frequency conversion speed regulation (using a frequency converter, the manufacturer is generally Mitsubishi, can also be specified), instead of speed regulation motor, the entire workpiece conveying system frequency conversion step-less speed regulation. (Speed range 0.5-4m / min)
Input, output and segmented transmission of the chamber roller table, step-less speed regulation, that is, it can run synchronously with the entire line, and can also run quickly, so that the steel can quickly travel to the work position or quickly exit to the discharge station purpose.
Adopt full line PLC programmable controller power, automatic detection and automatic search for fault point, sound and light alarm.
The equipment has a compact structure, a reasonable layout, and is very convenient for maintenance.
Roller cleaning
The roller brush cleaning system is equipped with a high-elastic nylon roller brush, a pill screw conveyor and its lifting mechanism. The high-strength nylon roller brush sweeps the projectiles during the rotation and sweeps them into the pill-receiving screw conveyor, and then the pill-receiving screw conveyors discharge the projectiles into the chamber and are taken away by the bottom of the shot blasting machine. Among them, the key component nylon roller brush has the following advantages: The composite nylon material with high elasticity Φ3mm is used, the hardness is moderate, the elasticity is large, the wear resistance is good, the bristles are firmly clamped, and the special tooling is used to stamp the bristles into blocks, and the bristles are not lost in the work. After the entire nylon roller brush is installed, the precision axle head guarantees the coaxiality. Good dynamic balance and stable work.
