DOCKSOLID Bulk Port Equipment offers clients effective methods of handling a variety of bulk commodities, including grain, coal, minerals, cement, biomass and many others. The brand includes extremely robust and reliable ship unloading systems, with a focus on flexibility of use and highly manoeuvrable mobile equipment. As part of this Buttimer Engineering offers a range of Standard, Heavy Duty and customised Environmental Port Unloading Hoppers that include state-of-the-art modernizations to minimise the potential of noise and air pollution.
Hoppers are designed to the customers specification, resulting in optimal results and increased profits.
The DOCKSOLID Eco hopper has a number of dust and environmental control techniques:
- Dust Thimble. The dust thimble is an extension of the hopper walls above the grid area, in order to create a sheltered space in which the loading grab can be opened. The dust thimble prevents exposure of the product to the wind or external influences while it is being dropped into the hopper and then dropped through the trash grid.
- Non-Return Valve (‘Flex-Flap’ System). The flex-flap mechanism is a one-way non-return valve system positioned beneath the trash grid. Made from steel and flexible rubber the flex-flap allows the product that has passed through the trash grid to fall freely into the hopper, but prevents dust rising upon impact with the hopper wall or other product.
- Extraction Filters. Dust extraction filters suck air out of the hopper and thimble at a rate required to create significant negative air pressure, keeping the product and dust subdued inside the hopper structure, while removing the dust from the air being extracted. The reverse-jet filter system collects dust from the extracted air in reusable filter bags, then periodically pulses compressed air through the filters to release the collected dust and return it to the product. When the grab is correctly positioned and opened by the operator, the loading process can be carried out with almost no dust and product loss.
- ATEX & Deluge Systems. Where there is a build-up of dust, there is an explosion risk. The DOCKSOLID hopper range can be customised with explosion panels, spark resistant mechanisms and gas deluge systems as required. The level of ATEX (Anti-Explosion) precautions necessary will depend on the products being handled, the surrounding environment and operations being carried out in the hopper’s vicinity.
