Pressure bulk tanks are mostly used in conventional systems onboard marine and offshore vessels. Lion’s pressure bulk tank, combined with our unique fluidisation floor, ensures quick and clean discharge. This allows the tank to be emptied completely by the perfect mixture of air and material. This Lion Bulk Handling solution is, without doubt, the most cost-effective way to fluidise cargo.
The cyclone dust collector is a traditional de-dusting unit designed to ensure that less material dust is released into the environment. Since the cyclone has a centrifugal effect, a dual vortex is required to separate air from material/fine dust. The main vortex spirals downward and carries most of the dust particles. The inner vortex, created near the bottom of the cyclone, spirals upward. This upward stream is cleaner air, which nonetheless still carries a small amount of dust particles. All the material/dust that has been separated by the cyclone is received and stored in the dust collector underneath. The dust collector is a small pressure tank that is pressurised when full and can be discharged to another destination.
A flap valve is a valve which opens by flipping a round or rectangular gate/wedge out of the path of the dry cargo. The distinct feature of a flap valve is the sealing surfaces between the flap and seats are planar, so flap valves are often used when a straight-line flow of dry cargo and minimum restriction is desired.
Loading bellows or loading chutes are used for efficient, dust-controlled discharging of dry, dusty bulk solids/materials into ships, barges, trucks or stockpiles. These loading spouts are provided with tapered inner cones to contain the flow of material and an outer bellow to provide for dust removal.
The key factor for good handling of dry material is flow. Obstructions must be avoided so as to achieve the required loading and discharge capacities. Loading filters (also known as lump catchers or rock catchers) will ensure that these obstructions can be collected when loading by this screen. The Lion Bulk Handling loading filter (single or double acting) will prevent any foreign object from being loaded into the dry material handling system. If any obstruction is located, it can easily be removed by hand.
The mucking ejector works based on the principle of convergent/divergent nozzle, as this provides the Venturi effect – creating a vacuum in the diffuser throat where the suction line is provided. At the suction line, the ejector is connected to a suction hose or to a piping system for vacuum cleaning of the inner side of the tanks. The outlet of the ejector is connected to a piping system, which brings the material back to the storage facility or to the de-dusting Unit. The ejector is supplied with air from the compressor (inlet).
Screw conveyors are among the oldest methods for handling dry bulk materials such as cement, barite, bentonite, fly ash and drill cuttings. The screw conveyor loading system consists of a family of stock components designed for assembly into custom configurations that meet specific material handling requirements. Our drive sections feature a rugged motor and gearing suited to handling the weight and density of your material. All troughs are constructed of heavy-duty steel plate coated with industrial-strength epoxy paint. Sealed hanger and end bearings support the long-wearing steel auger. Super-duty coupling shafts connect the auger between sections. Options include electric pushbutton start and speed control, safety gates and an emergency stop device.
Surge tanks are mostly used in mud mixing systems on offshore drilling rigs and supply vessels. The Lion-designed surge tank, combined with our mass flow fluidiser and backflow prevention unit, ensure a quick and efficient mixing of barite and bentonite. The Lion backflow prevention unit eliminates the backflow of drilling mud into the mass flow fluidiser and into the surge tank if the suction valve on the shearing mixer is accidentally left open when mixing stops. The backflow prevention unit utilises a vacuum transducer that senses when vacuum has been compromised and closes the automated valve on the shearing mixer suction side. Designed by Lion Bulk Handling, this solution is by far the most cost-effective way to discharge the material in
