Cleaning device special for PDC drill bits

Abstract

The invention relates to a cleaning device special for PDC drill bits. The cleaning device special for the PDV drill bits comprises a base, a rotary shaft and a disk. The base is provided with brake trundles. One end of the rotary shaft is connected with the middle of the upper surface of the base, and the other end of the rotary shaft is fixedly connected with the middle of the disk. A first cleaning tank, a second cleaning tank and a third cleaning tank are arranged on the upper surface of the disk, and the upper surface of the first cleaning tank, the upper surface of the second cleaning tank and the upper surface of the third cleaning tank are open. Drain holes are formed in the bottom surfaces of the cleaning tanks, and water inlets are further formed in the side faces of the cleaningtanks. Drain pipes are connected to the drain holes and connected with a water collection tank. Water inlet pipes are connected to the water inlets and connected with a water supply tank, and water inlet pumps are further connected to the water inlet pipes in series. A water gun and an electric cleaning bush are arranged in the first cleaning tank, an ultrasonic cleaning machine is arranged in the second cleaning tank, and cleaning liquid is contained in the third cleaning tank. The cleaning device special for the PDV drill bits has the advantages that water can be effectively supplied in thecleaning process, continuous cleaning is ensured, and thus the cleaning efficiency is improved.

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 special cleaning device for PDC drill bits, which includes a base, a rotating shaft, and a disc. The base is provided with casters with brakes, and the bottom of the disc is provided with a circular groove. The rotating shaft One end is connected to 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: the first cleaning box, the second cleaning box, and the third cleaning box, the bottom surfaces 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 with the 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 cleaning machine, and the third cleaning tank is filled with cleaning liquid, realizing the design of a special cleaning device for PDC drill bits Reasonable, good cleaning effect and high cleaning efficiency; however, during the cleaning process, the water in each cleaning tank will continue to drain outward through the drain hole and then through the drain pipe, so the water in the cleaning tank will continue to decrease. When the amount of water is reduced to a certain extent, the cleaning effect will be affected; furthermore, in order to ensure the cleaning effect, it is necessary to stop the car and add water to each cleaning tank, but this method cannot meet the continuous cleaning, thereby affecting the cleaning efficiency
