The utility model discloses a
coal slime
water treatment and cyclic utilization
system of a kilometer drilling
machine, which comprises a
coal water screening and collecting all-in-one
machine, a
coal slime water
centrifugal separation device and a precision filter, the
coal water screening and collecting all-in-one
machine is arranged at the front end of the kilometer drilling machine, and a gas-liquid separator of the kilometer drilling machine is used for separating a
gas phase from the coal slime water; separated slime water is introduced into a
coal water screening and collecting all-in-one machine to be subjected to rough
filtration treatment, and rough separation and
temporary storage of
solid and liquid are achieved; coal slime treated by the
coal water screening and collecting all-in-one machine is pumped to a centrifugal
solid-liquid separator of the coal slime water
centrifugal separation device for secondary
solid-liquid separation, liquid obtained after secondary solid-liquid separation is treated by a precision filter, and treated clear water is introduced into a clear water tank to be reused by a kilometer drilling machine. Backwash
wastewater of the precision filter flows back to the coal water screening and collecting all-in-one machine for retreatment. In-situ efficient treatment of slime water and cyclic utilization of clear water can be achieved, the problems of underground water shortage, large drainage pressure and water
sump desilting are solved, the production cost is reduced, and the
working environment is improved.
