Cleaning device special for PDC drill bits

Abstract

The invention relates to a special cleaning device for PDC drill bits, comprising a base, a rotating shaft, and a disc. The base is provided with casters with brakes. One end of the rotating shaft is connected to the middle part of the upper surface of the base, and the other end is fixedly connected to the middle part of the disc; The upper surface of the disc is provided with the first cleaning box, the second cleaning box and the third cleaning box with openings on the upper surface, and the bottom surface of each cleaning box is provided with drainage holes, and the sides of each cleaning box are also provided with water inlet holes and drainage holes. The drain pipe is connected to the water collection tank, the water inlet is connected to the water inlet pipe, the water inlet pipe is connected to the water supply tank, and the water inlet pump is connected in series on each water inlet pipe; the first cleaning tank is equipped with a water gun and an electric For cleaning brushes, an ultrasonic cleaning machine is arranged in the second cleaning box, and cleaning liquid is installed in the third cleaning box. The advantage of the present invention is that: the present invention can effectively supply water during the cleaning process, ensure continuous cleaning, and further improve cleaning efficiency.

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
