Novel PCD drill bit cleaning device

Abstract

The invention relates to a novel PCD drill bit cleaning device which comprises a base, a rotary shaft and a disc. The rotary shaft is fixedly connected with the base and the disc. Three cleaning boxeswith openings in the upper surfaces are arranged on the upper surface of the disc, a water drainage hole and a water inlet hole are formed in the bottom face and the side face of each cleaning box, awater drainage pipe is connected to each water drainage hole, and a filter screen is arranged at each water drainage hole. Each filter screen comprises a rough filtering 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 side to the water outlet side. Supporting frames are symmetrically hinged to the two sides of each of the upper end and the lower end of the rotary shaft correspondingly. The other ends of the supporting frames at the upper end are fixedly connected with the bottomface of the disc through lock pins. The other ends of the supporting frames at the lower end are fixedly connected with the upper surface of the base through lock pins. The novel PCD drill bit cleaning device has the beneficial effects that the occupied space can be reduced, transportation can be facilitated, and stability between the disc and the rotary shaft and stability between the base and the rotary shaft can be increased; and water can be effectively supplied in the cleaning process, cleaning continuity can be guaranteed, and then the cleaning efficiency can be improved.

Description

technical field [0001] The invention relates to the field of petroleum mechanical equipment research, in particular to a novel PCD 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 ...

Problems solved by technology

[0009] In response to the above phenomenon, someone proposed to connect the rotating shaft and the base flexibly, but in the specific use process, there are still certain defects: 1. Since the disc and the rotating shaft and the base and the rotating shaft are flexibly connected, the disc and the rotating shaft There is a lack of stability between the shafts and between the base and the rotating shaft, so the disk cannot be guaranteed to be in a horizontal state, and the cleaning of each drill bit cannot be guaranteed; 2. During the cleaning process, the water in each cleaning tank will pass through the drain hole and then through the drain The pipe is continuously drained outward, so the water in the cleaning tank will continue to decrease. After the water volume decreases to a certain extent, the cleaning effect will be affected; 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 cleaning requirements. Continuous, which in turn affects the cleaning efficiency
