Novel PCD drill bit cleaning device

Abstract

The invention relates to a novel PCD drill bit cleaning device, which comprises a base, a rotating shaft, and a disc, and the rotating shaft is fixedly connected to the base and the disc respectively; the upper surface of the disc is provided with three cleaning boxes with openings on the upper surface, and each cleaning box The bottom surface and the side are provided with drain holes and water inlet holes, and the drain holes are connected with drain pipes, and the drain holes are provided with filter screens, which include a coarse filter layer, an initial effect layer, and a medium filter layer arranged in sequence from the water inlet to the water outlet. effect layer, high-efficiency layer and purification layer; a support frame is symmetrically hinged on both sides of the upper end and the lower end of the rotating shaft, the other end of the upper end support frame is fixedly connected with the bottom surface of the disc through a lock pin, and the other end of the lower end support frame is fixed through a lock pin. The pin is fixedly connected with the upper surface of the base. The advantages of the present invention are: the present invention can reduce the occupied space, facilitate transportation and increase the stability between the disk and the rotating shaft and between the base and the rotating shaft, and can effectively supply water during the cleaning process to ensure continuous cleaning. Thereby improving cleaning efficiency.

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
