Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning device for oil drilling bits. Background Technology

[0002] With the rapid development of the petroleum industry, drilling operations in oil extraction have become increasingly complex and sophisticated. As the core tool in oil extraction, the drill bit operates in a harsh environment, typically becoming contaminated with large amounts of mud, rock debris, and other impurities. These contaminants not only affect the cutting efficiency and lifespan of the drill bit but also adversely impact subsequent oil extraction operations. Therefore, drill bit cleaning is a crucial step in the oil extraction process.

[0003] However, existing drill bit cleaning devices still have certain shortcomings. For example, oil drill bits usually have complex geometries, which leads to many blind spots during the cleaning process. Traditional cleaning methods involve surface rinsing, but it is difficult to reach these complex blind spots, which causes dirt to accumulate in these areas and affects the cleaning effect. Manual brushing can clean specific areas, but it is inefficient and cannot guarantee thorough cleaning. Secondly, drill bit cleaning requires a lot of water resources and lacks practicality. Utility Model Content

[0004] The purpose of this utility model is to provide an oil drilling bit cleaning device that can continuously shake the drill bit inside the cleaning tank during cleaning, thereby constantly contacting the brush plates on both sides, thus avoiding cleaning dead corners and improving the comprehensiveness of cleaning.

[0028] The inner surface of the cleaning tank 8 is provided with a slot 22, and an activated carbon filter 23 is slidably connected to the inner surface of the slot 22. A limit plate 24 is fixedly connected to the right surface of the activated carbon filter 23, and a bolt 25 is threadedly connected to the inner surface of the limit plate 24. A first rigid pipe 26 is fixedly connected to the inner surface of the wastewater tank 1. A circulation pump 27 is fixedly connected to the end of the first rigid pipe 26 away from the wastewater tank 1. A second rigid pipe 28 is fixedly connected to the output end of the circulation pump 27. The second rigid pipe 28 is located away from the circulation pump 27.

[0029] Working principle: During operation, the drill bit to be cleaned is placed in the cleaning tank 8. Then, the waterproof dual-axis motor 11 is started, driving the lead screw 12 to move the two brush plates 14 towards each other under the action of the connecting frame 13. This allows the bristles on the brush plates 14 to contact the drill bit inside the cleaning tank 8. Subsequently, the circulation pump 27 and motor 20 are started. Under the action of the circulation pump 27, water from the wastewater tank 1 is absorbed through the first rigid pipe 26 and then sprayed out through the second rigid pipe 28, the cavity plate 29, and the nozzle 30, thereby flushing and cleaning the dirt on the surface of the drill bit inside the cleaning tank 8. Under the action of the motor 20, the rotating shaft 21 drives the turntable 18 to rotate. Then, under the action of the connecting column 17, the long plate 16, and the fixed column 15, the entire cleaning tank 8 moves along the slide bar under the action of the slider 7. 6. The drill bit moves back and forth. Due to inertia, the drill bit inside the cleaning tank 8 will shake and continuously contact the bristles on the brush plate 14 during rinsing and cleaning, thereby effectively removing dirt from the dead corners of the drill bit and improving the cleaning effect. The wastewater after cleaning is filtered through the activated carbon filter 23 and falls into the wastewater tank 1 for storage. It is then circulated by the circulation pump 27 to reduce water waste. When the activated carbon filter 23 needs to be replaced, simply loosen and remove the bolt 25 to release the restriction on the activated carbon filter 23. Then, pull the activated carbon filter 23 out along the slot 22 to complete the disassembly. Then, insert the new activated carbon filter 23 into the slot 22 and tighten the bolt 25 to complete the installation of the new activated carbon filter 23.
