Description

Wheel type lifting feeding machine

Technical Field

The utility model belongs to the field of material conveying, and particularly relates to a wheel type lifting feeding machine.

Background

Oil-based muds are widely used in shale gas drilling processes. Oil-based mud is mainly prepared from diesel oil or low-toxicity mineral oil, is high in cost, generates a large amount of oily drill cuttings in the using process, and seriously affects the ecological environment near a well site. In order to reduce the drilling cost and meet the requirement of environmental protection, an oil-containing drilling cutting processing system is required to be arranged at the drilling site. The oily drilling cuttings are firstly collected to a hopper in the drilling process, the height difference between the hopper and a feeding hole of a processing system is about 2-3 meters, and the oily drilling cuttings need to be lifted and conveyed to the processing system through a feeding device. The oil content of the oil-containing drilling cuttings is about 20%, the water content is about 10%, the solid content and the other content are about 70%, the liquid phase separated by the treatment system is recycled, and the separated solid phase enters the subsequent treatment process.

Because the solid content in the oil-containing drilling cuttings is higher, the traditional feeding device generally adopts a conveying mode of a screw conveyor or a concrete conveying pump and a conveying pipeline. When adopting screw conveyer feed, screw conveyer is very little with ground contained angle usually, will reach about 3 meters conveying height, can only reach the requirement of material lifting through elongated screw conveyer, the screw conveyer who uses has surpassed ten meters now, lead to feedway area too big, and in long distance transportation process, loose material grain organization is smashed into finer granule by helical blade stirring easily, the separation degree of difficulty of follow-up processing system has been increased, lead to solid phase content to increase in the liquid phase of separation, the separation effect variation. When the mode of feeding by adopting the concrete delivery pump and the delivery pipeline is adopted, material particles are also easy to be broken into smaller particles under the high-pressure action of the concrete delivery pump, so that the separation effect of a treatment system is poor, and the concrete delivery pump has a complex structure, high equipment cost and high failure rate in the field use process.
