The invention discloses three-proofing complete equipment for drilling and
punching. The three-proofing complete equipment is characterized by comprising an orifice sealing device, a
coal-water collecting box, a
coal-water separation vehicle and a
centrifugal separator, wherein the orifice sealing device is used as an inlet end for collecting
coal-water
slag and gas in a
drill hole to seal the periphery of the
drill hole, and the orifice sealing device is of a cylindrical
barrel structure; the coal-water collecting box comprises an upper box body and a lower box body; one side of the upper box body is hinged to one side of the lower box body; the upper box body and the lower box body are rotationally closed to form a box body which is buckled up and down, and a sealing opening which is in
butt joint with the orifice sealing device is formed in the side wall of the box body; the coal-water separation vehicle comprises a gas-liquid separation device, a lifting device and a drainage tank, and a liquid inlet of the gas-liquid separation device communicates with a lower connector of the coal-
water collection tank; and the
centrifugal separator comprises a horizontal spiral centrifugal
machine and is used for carrying out secondary separation on the separated
sewage of the drainage tank. According to the equipment, orifices can be effectively protected in the coal mine underground drilling and
punching process, meanwhile, coal-water
slag generated in the construction process can be subjected to multi-stage
filtration, and filtered
sewage is recycled.
