Big Bag Discharge and Loading System

Big Bag Discharge and Loading System

Description

Mobile big bag discharge bulk truck loading systems are used for efficient discharging of big bags and dust-free loading of bulk trucks. The system consists of a mobile platform, big bag discharger, loading screw, telescopic loading chute, and dust collector. The system can be towed by a forklift and a screw conveyor can be brought to a horizontal position for easier and safe transport.

Operation

Mobile system is placed near the desired bulk truck to be loaded. The screw conveyor is lifted to 45 º angle with the help of automatic screw jacks.

Big bags brought by forklift are placed on big bag discharging hopper. Big bag outlet spout is untied by the operator or cut by a built-in cutting knife instantly and the big bag is emptied.

An important component here is the cutting knife that is optionally available that cuts the big bags very quickly so that the solid material is quickly discharged into the hopper.

Optionally also available are the air jets to aid product flow inside the hopper and vibrator to ensure complete and quick flow of the material. Material inside the hopper is then transferred by inclined screw conveyor to the top of the truck and discharged into the bulk truck through the loading bellow.

Dust emission is prevented by a dust collector which is connected to the loading bellow and big bag discharging hopper. 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.

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 filling is started, a built-in dust collector evacuates the air trapped in the vessel to increase the product flow rate.

The level sensor placed at the bottom monitors the product level in the tanker truck and stops loading when the truck is full. Loading bellow retracts to the top position automatically.

When loading is over, the screw jack lowers the screw conveyor automatically to the horizontal position. Loading bellow is used for safe and dust-free loading of the bulk truck.

Components of the system

Big Bag Discharge Hopper

This is used for discharging big bags and transfers the material to the screw conveyor. It has a capacity of 1 m3 and is made of Stainless steel. It has steel grating for simpler handling of big bags.

Following options are available:

  • Cutting knife to cut the big bags instantly when put.
  • Fluidizing air jets to aid product flow inside the hopper.
  • Vibrating engine to ensure a good flow of the product.

Screw Conveyor

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.

Screw Jack

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 45º 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.

Loading Bellow

The loading bellow is 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.

Air Compressor

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. One cabled remote control and one wireless remote control are used in parallel. All the components can be controlled from the electrical panel.

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 towbar, forklift, or vehicle. It is made of carbon steel. It has 4 wheels and has swivel jacks to provide rigidity during truck loading.
