Mobile Truck Loading System with Vacuum System
In this system the product that is to be loaded is pumped in by a vacuum system. The product inlet is the beginning of the pipeline, and then there is a mini vacuum silo / cyclone that pull in the product. Once the product is in the hopper then it is conveyed up by screw conveyor and finally loaded to by the bellow on to the truck.
Mobile bulk material vacuum and truck loading systems are used for efficient conveying of materials to trucks. The system consists of a mobile platform, flexible suction hose, vacuum receiver, pump, motor, loading screw, telescopic loading chute, and dust collector. The screw conveyor can be brought to a horizontal position for easier and safe transport.
Mobile system is placed near the bulk truck to be loaded and the screw conveyor is lifted to 45 º angle with the help of automatic screw jacks.
Materials vacuumed by vacuum blower with a flexible suction hose are conveyed to the cyclone (vacuum receiver) of the system. Material inside the cyclone is then transferred by inclined screw conveyor to the top of the truck and discharged into the bulk truck through the telescopic chute. Dust emission is prevented by a dust collector which is connected to the telescopic chute.
Material coming from the screw conveyor is discharged through the telescopic chute. At the beginning of truck loading, the chute is lowered and stops automatically when it reaches to tanker inlet. Polyurethane coated discharge cone fits vessel inlet to prevent any dust emission during truck loading. Material falls freely through the inner side of the bellow. After bulk tanker truck filling is started, a built-in dust collector evacuates the air trapped in the vessel to increase the product flow rate. Dust content in the air is trapped by filter units and sent back to the hopper with the help of automatically operated pulse jet valves. The level sensor placed at the bottom monitors the product level in the tanker truck and stops loading when the truck is full. Telescopic chute retracts to the top position automatically.
Telescopic chute is used for safe and dust-free loading of the bulk truck. The dust collection system captures the dust created during the emptying of big bags and the loading of the tanker truck. Once the dusty air is filtered, the clean air is thrown out and the dust collected inside the filter is transferred to the loader hopper. The whole system is connected to this wheeled mobile chassis that allows the transportation of the system to the desired location by tow-bar, forklift, or vehicle.
When loading is finished, the screw jack lowers the screw conveyor automatically to the horizontal position when the system is to be moved to another location.
Various Parts of the System
Vacuum Receiver/ Cyclone
The material vacuumed by the flexible suction hose is conveyed to the vacuum receiver. Then the material is transferred from the cyclone to the screw conveyor. Its volume is 1 m3 and is made of ST-37 Carbon Steel.
Flexible Suction Hose
The flexible suction hose is used for vacuuming materials from any desired point or medium to the screw feeder. Its length is 12 meters and is made of Rubber (Antistatic rubber is available upon request). It has a suction/nozzle.
The screw conveyor enables the transfer of the material conveyed from cyclone to tanker loading bellow. It can be brought to a horizontal position when the system is to be moved to another location. It is made of ST-37 Carbon Steel. It is driven by an electrical motor with a gearbox. The inclination Control is by screw jacks.
It enables the movement of the screw conveyor and telescopic chute upwards and downwards. When the system is installed in the area, the screw conveyor is lifted to 45 º angle with the help of automatic screw jacks. When loading is over, the screw jack lowers the screw conveyor automatically to the horizontal position. 2 units work in parallel.
The telescopic chute used for safe and dust-free loading of the bulk truck. It has a capacity of 250 m³/h. It is made of carbon steel and driven by an electrical motor with a gearbox.
Dust Collection System
The dust collection system captures the dust created during the loading of the tanker truck. Once the dusty air is filtered, the clean air is thrown out and the dust collected inside the filter is transferred to the screw feeder. It is a cartridge type jet pulse filter with a fan made of carbon steel. It has 8 cartridges. The operating pressure is 4-6 bars.
It is used to supply pressurized air needed to operate a dust collector. It has a maximum pressure of 6 bars.
Electrical Control Panel
There is an electrical panel to control the equipment in the system. It has both cabled and wireless remote controls and is based on Siemens S7 1200 PLCs.
The Mobile Chassis
The whole system is connected to this wheeled mobile chassis that allows the transportation of the system to the desired location by tow-bar, forklift, or vehicle. It is made of carbon steel. It has 4 wheels and has swivel jacks to provide rigidity during truck loading.
Advantages of Using a Vacuum System
- Quick loading
- Less manpower is used.
- Environment friendly as there is less dust in the environment
- No loss of material
