PDC drill head cleaning system

Abstract

The invention relates to a PDC bit cleaning system, comprising a base, a rotating shaft, and a disc. The rotating shaft includes a fixed shaft and a telescopic shaft. A pair of pin holes are provided at the upper end of the fixed shaft, and several pairs of positioning holes are provided at the lower end of the telescopic shaft. The support pin is inserted in the pin shaft hole and the positioning hole; the lower end of the fixed shaft is connected to the middle of the upper surface of the base, and the upper end of the telescopic shaft is located in the circular groove; there is also a support frame hinged symmetrically on both sides of the upper end of the telescopic shaft. The other end of the disc is fixedly connected with the bottom surface of the disc through the lock pin; the upper surface of the disc is provided with three cleaning boxes with openings on the upper surface, and the bottom surface of each cleaning box is provided with drain holes, and the drain holes are connected with drain pipes. The water collection tank is connected; the first cleaning tank is equipped with a water gun and an electric cleaning brush, the second cleaning tank is equipped with an ultrasonic cleaner, and the third cleaning tank is filled with cleaning fluid. The advantages of the present invention are: the present invention can be applied to cleaning drill bits of different heights and can increase the stability of both the disc and the rotating shaft.

Description

technical field [0001] The invention relates to the research field of petroleum machinery and equipment, in particular to a drill bit cleaning device. Background technique [0002] The abbreviation of diamond compact (PDC) drill bit is a drilling tool commonly used in the oil drilling industry. [0003] The performance of PDC products continues to improve. Over the past few years, the quality and type of PDC cutting teeth have changed dramatically. If you compare the teeth of the 1980s with today's teeth, the difference is considerable. Due to the mixing Due to the changes in technology and manufacturing process, the quality and performance of today's cutting teeth are much better, which greatly improves the erosion resistance and impact resistance of the drill bit. [0004] Engineers also optimized the interface between the tungsten carbide substrate and the synthetic diamond to increase the toughness of the cutting teeth. Innovations in layered diamond processing have al...

Problems solved by technology

[0007] In the prior art, because the drill bit has been drilling underground for a long time, there will be a large amount of impurities on the surface after use. If it is not removed, it is easy to accelerate the wear of the drill bit and reduce the service life of the drill bit. Usually, the staff removes the drill bit. Cleaning and then reinstalling is cumbersome and less efficient

[0008] After retrieval, the patent CN204620562U discloses a PDC bit cleaning system, which includes a base, a rotating shaft, and a disk. The base is provided with casters with brakes, and the bottom of the disk is provided with a circular groove. One end of the rotating shaft It is connected with the middle part of the upper surface of the base, the other end of the rotating shaft is located in the circular groove, the disc can rotate around the rotating shaft, and the upper surface of the disc is provided with: a first cleaning box , the second cleaning box, the third cleaning box, the bottom surface of the first cleaning box, the second cleaning box, and the third cleaning box are all provided with drain holes, and the drain holes are connected with drain pipes, and the drain pipes are connected to the collection The water tank is connected, the first cleaning tank is equipped with a water gun and an electric cleaning brush, the second cleaning tank is equipped with an ultrasonic cleaning machine, and the third cleaning tank is filled with cleaning liquid, which realizes a reasonable design of the PDC drill bit cleaning system. The cleaning effect is good and the cleaning efficiency is high; however, this cleaning system is only suitable for cleaning drills of a specific height, not for cleaning drills of different heights, and for batch cleaning of drills, drills of different heights need to be matched A specific bit cleaning system, so the cleaning cost is relatively high; in addition, because the disc and the rotating shaft are movably connected, there is a lack of stability between the two, so it cannot be guaranteed that the disc is in a horizontal state, and the cleaning of each bit cannot be guaranteed
