Drill bit cleaning system

Abstract

The invention relates to a drill bit cleaning system. The drill bit cleaning system comprises a base, a rotary shaft and a disc. The rotary shaft comprises a fixed shaft body and a telescopic shaft body. A pair of hinge pin holes is formed in the upper end of the fixed shaft body. A plurality of pair of positioning holes are formed in the lower end of the telescopic shaft body. Rest pins are inserted into the hinge pin holes and the positioning holes, so that the fixed shaft body and the telescopic shaft body are fixed together. The lower end of the fixed shaft body is connected with the middle of the upper surface of the base, and the upper end of the telescopic shaft body is located in a round groove. Three cleaning tanks with the upper surfaces open are arranged on the upper surface ofthe disc, drain holes are formed in the bottom surfaces of the cleaning tanks, and filter screens are arranged at the drain holes. Each filter screen comprises a rough filtration layer, a primary efficiency layer, a medium efficiency layer, a high efficiency layer and a purification layer which are sequentially arranged from the water inlet position to the water outlet position. Water inlets are further formed in the side faces of the cleaning tanks. The drain holes are connected with a water collection tank through a drain pipe, and the water inlets are connected with a water supply tank through a water inlet pipe. The drill bit cleaning system can be used for cleaning drill bits with different heights, water can be effectively supplied in the cleaning process, continuous cleaning is ensured, and the cleaning efficiency is improved accordingly.

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 drill bit cleaning system, 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 middle part of the upper surface of the base is connected, 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 water collection tank. connection, the first cleaning box is equipped with a water gun and an electric cleaning brush, the second cleaning box is equipped with an ultrasonic cleaning machine, and the third cleaning box is filled with cleaning liquid, which realizes a reasonable design of the drill cleaning system and a good cleaning effect. Better, the technical effect of higher cleaning efficiency; but this cleaning system is only suitable for cleaning drill bits of a specific height, not suitable for cleaning drill bits of different heights, and then for batch cleaning of drill bits, drill bits of different heights need to be equipped with specific Drill bit cleaning system, so the cleaning cost is relatively high; in addition, because the water in each cleaning tank will be continuously drained out through the drain hole and then through the drain pipe during the cleaning process, the water in the cleaning tank will continue to decrease, and the water volume will decrease to After a certain level, it will affect the cleaning effect; and 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, which will affect the cleaning efficiency
