Hydraulic Cutting Drill Hole Cinder Conveying and Separating Device

Abstract The present invention belongs to the field of gas extraction drill hole cinder cleaning of coal mines, and relates to a hydraulic cutting drill hole cinder conveying and separating device used for separating cinders and gas in a drill hole during processes of drilling with a drill rod and cutting, comprising a drill hole cinder collecting device, a cinder collecting box, a cinder conveying pump and a cinder separator which are connected in sequence through slurry pipes and an automatic control system used for controlling start-stop of the cinder conveying pump and the cinder separator; and the drill hole cinder collecting device is sleeved on the end of a drill hole in the outer side of a drill rod, the drill hole cinder collecting device, the cinder collecting box and the cinder conveying pump are connected to a main extraction pipe through gas extraction pipes, and a mixing impeller is arranged in the cinder collecting box. The device can realize automatic start-stop, is simple to operate, and can effectively reduce the labor input cost of cinder cleaning work and the working strength of on-site staff.
