The invention discloses a fully-sealed
wind power slagging gas-drainage deep
well drilling system and method. The fully-sealed
wind power slagging gas-drainage deep
well drilling system comprises a drilling rod with inner holes, an inverted-
spinning smashing dust-collection
drill is arranged at the front end of the drilling rod, and the rear portion of the drilling rod is connected to a drilling
machine. An orifice-sealed
pipe, sealing fillers and a sealed pressing cover are arranged on the drilling rod. An air inlet portion with annular section is formed between the orifice-sealed
pipe and the outer wall of the drilling rod, and the air inlet portion is connected with a
movable type air compressor through a first connecting
pipe. The rear end of the drilling rod is connected with a second connecting pipe through a pneumatic rotary connector, the second connecting pipe is connected with a drainage conveying pipeline slagging device, and the slagging port of the slagging device is connected with a slagging cylinder. The air outlet of the slagging cylinder is connected with a gas drainage pump through a third connecting pipe, and the gas drainage pump is connected with a gas drainage pipe. According to the fully-sealed
wind power slagging gas-drainage deep
well drilling system and method, pressing feeding type
wind force in the outer annular space of the drilling rod and the drainage type
wind force of the inner holes of the drilling rod can be utilized to
discharge the
coal scraps smoothly to carry out
solid-
gas separation, fully-sealed type wind power
scrap discharge is achieved, the fact that hole-drilling operation is conducted continuously and safely is ensured, and working efficiency is improved.
