MOBILE PLANT FOR DRILLING WASTE PROCESSING Russian patent published in 2017 - IPC B09B3/00 

FIELD: mining engineering.

SUBSTANCE: mobile drilling waste processing plant contains functional modules, including a set of devices connected in a process sequence by pumps and conveyors, and is characterized in that the plant comprises a loading and preparation module, a filtration module, a mixing and pressing module, a pre-hardening and unloading module for briquettes, while the loading and preparation module contains a receiving and buffer tank with a mixer, receiving hoppers for natural sand, sorbent and plasticiser, and connected by augers dispensers with the receiving and buffer tank. The filtering module contains a slurry pump, by means of which the receiving and buffer tank is connected to filter press. The filter press is connected to filtrate drainage tank, the pumps and the filtrate cleaning filter, and the belt conveyors is connected to the two-shaft mixer. The mixing and pressing module contains a cement hopper and a hardening accelerator hopper connected by the auger dipensers with ther two-shaft mixer in which a hopper for discharging a mixture of dehydrated drilling waste, cement and hardening accelerator is connected to briquetting press hopper. The module for preliminary hardening and unloading of briquettes contains a loading/unloading belt conveyor and a belt stacking conveyor to transfer briquettes for hardening, and connected to the briquetting press from the mixing and pressing module. The receiving and buffer tank from the waste loading and preparation module is connected to the filter press from the filtration module by the slurry pump.

EFFECT: increasing mobility of the plant and reducing transportation costs of the drilling waste processing plant into a ready-made, solid, free-flowing moulded construction material - an artificial stone.
