INSTALLATION FOR PREPARATION OF THE ARSENIC-CONTAINING SULFIDE WASTES FOR THE STORAGE Russian patent published in 2007 - IPC C01G28/00 B09B3/00 

FIELD: chemical industry; devices for preparation of the arsenic-containing sulfide wastes for the storage.

SUBSTANCE: the invention may be used at preparation of the industrial arsenic-containing sulfide wastes for the storage. The installation for preparation of the arsenic-containing sulfide wastes for storage includes: the waste bin (1), the fitting pipe (3) used for the wastes feeding from the bin, is connected to the feeder (4) with the loading device (5) of the press (2) used for forming the cakes from the wastes. The unloading device (6) of the press through the system of the pushers (7), (8) is connected to the conveyor (9) of the device used for deposition of the protecting coating on the cakes. The device for deposition of the protecting coating on the cakes also includes the unpowered roller conveyor (10), which rollers (11) are dipped in the liquid bitumen, and the spattering device (14) located above the unpowered roller conveyor is connected by the heated pipeline with the liquid bitumen heated tank (17). The ventilation roof hood (7) is installed over the conveyer and the system of the pushers and is linked by the ventilation duct through the filter (28) to the loading device of the press. Over the unpowered roller conveyor (10) there is the ventilation roof hood connected with open air by the ventilation duct through the additional filter (32). The block of cooling of the bituminized cakes includes: the transporter (21) connected to the unpowered roller conveyor (10), the sprinkler (22) located over the transporter(21) connected to the water cooling device (24). The invention allows to reduce the danger of the arsenic-containing cakes.

EFFECT: the invention ensures reduction of the danger of the arsenic-containing cakes.
