    Abstract: A grit removal system for tanks with a need to remove settled solids (e.g., anaerobic digester tank) is described. The system is especially suitable for a large tank, preferably having a flat floor, and it works well while submerged under a liquid. Specifically, a periphery-driven rack & pinion mechanism drives a shaft to rotate about a center pivot, and scrapes settled solids towards tank periphery, where the solids fall into a pit on the tank floor. A drainage opening inside the pit, when opened by a valve, is used to flush out the solids through a standpipe into a settlement tank for final dewatering and solid disposal. The system is compatible for continuous tank operation, and is useful for stirring tanks requiring periodic sediment removal.

The separating bars traverse a track formed within the body of the separating device and through respective tank, cleaning, free roll, and compression regions in a controlled cleaning system. The separating bars are detached from one another and allowed to move through the separating device independently of one another. The device removes the use of chains to connect cleaning bars traversing through a cleaning system.

  • Publication number: 20120012540
    Abstract: A grit removal system for tanks with a need to remove settled solids (e.g., anaerobic digester tank) is described. The system is especially suitable for a large tank, preferably having a flat floor, and it works well while submerged under a liquid. Specifically, a periphery-driven rack & pinion mechanism drives a shaft to rotate about a center pivot, and scrapes settled solids towards tank periphery, where the solids fall into a pit on the tank floor. A drainage opening inside the pit, when opened by a valve, is used to flush out the solids through a standpipe into a settlement tank for final dewatering and solid disposal. The system is compatible for continuous tank operation, and is useful for stirring tanks requiring periodic sediment removal.

  • Patent number: 7918994
    Abstract: A system for removing contaminant from sulfur to a level that allows re-processed sulfur to reenter a supply chain. The system melts contaminated sulfur, filters the molten sulfur, and then dispenses the less contaminated sulfur after filtering it. More specifically, solid contaminated sulfur enters a settling tank, while heated molten sulfur circulates through the system and the settling tank. The circulation of the molten sulfur assists in the melting process of the solid sulfur, allowing the solid sulfur to melt efficiently. In preferred embodiments of the system, the system uses steam jacked sulfur lines and steam tracing to maintain temperatures for melting the solid sulfur and maintaining the molten state of the sulfur circulating through the system. Furthermore, the system comprises a programmable logic controller, which controls motors, pumps, valves, and environment monitoring instruments.
