[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figures 1 to 4 , the utility model provides a technical solution:
[0027] A cooling device for a drill bit for oil exploration comprises a cooling box 1, wherein a transparent glass 2 is inlaid and installed on the left side of the front end of the cooling box 1, a water tank cover 3 is movably installed on the left side of the top of the cooling box 1, a first water pump 4 and a second water pump 5 are fixedly installed on the top of the cooling box 1 on the right side of the water tank cover 3 from the front to the back, a sewage outlet 6 is opened on the right side of the cooling box 1, a coolant storage chamber 11 and a cooling chamber 12 are respectively arranged on the left and right sides of the interior of the cooling box 1, a sewage discharge component 8 is arranged inside the cooling chamber 12, and the sewage discharge component 8 comprises a rotating rod 81, and the rotating rod 81 is movably installed inside the cooling chamber 12. The bottom of the cooling chamber 12 is located below the rotating rod 81 and is fixedly installed with a filter plate 84. The upper end of the inner wall of the cooling chamber 12 is fixedly installed with a high-pressure nozzle 14. The inner wall of the cooling chamber 12 is located below the high-pressure nozzle 14 and is fixedly installed with a drain plate 15. Four groups of fan plates 82 are fixedly installed on the surface of the rotating rod 81. The ends of the fan plates 82 away from the rotating rod 81 are fixedly installed with bristles 83. The fan plate 82 installed on the left side of the rotating rod 81 is directly opposite to the bottom of the drain port of the drain plate 15. The bottom of the cooling chamber 12 is inclined toward the coolant storage chamber 11, and the right side of the filter plate 84 is inclined toward the sewage outlet 6.
[0028] By adopting the above technical solution, when in use, first open the water tank cover 3, inject the coolant into the coolant storage chamber 11, observe the amount of coolant injected through the transparent glass 2, and after the coolant is injected into the coolant storage chamber 11, the coolant will also enter the cooling chamber 12 through the reflux groove 13. When injecting the coolant, it should be noted that the coolant in the cooling chamber 12 cannot exceed the height of the sewage outlet 6. After the preparation work is ready, start the first water pump 4 and the second water pump 5 in turn. The second water pump 5 supplies water to the high-pressure nozzle 14 through the water supply pipe 41. The drill bit is placed in the cooling chamber 12 through the cooling column 71. When the drill bit enters the cooling chamber 12, the high-pressure nozzle 14 cleans the drill bit. While cooling the drill bit, the drill bit can also be rinsed. After rinsing the drill bit, the liquid flows to the drain plate 15 The liquid flows toward the lower end through the water outlet of the drainage plate 15, and the liquid flowing out through the drainage plate 15 just falls on the fan plate 82. The fan plate 82 is impacted by the water and rotates through the rotating rod 81. At this time, the liquid falls on the filter plate 84 after touching the fan plate 82. After being filtered by the filter plate 84, the liquid flows toward the coolant storage chamber 11 due to the inclination of the bottom of the cooling chamber 12, and finally flows back to the coolant storage chamber 11 through the reflux groove 13. When the liquid falls on the filter plate 84, the filter plate 84 will filter the mud, sand and gravel in the liquid for filtering, and the rotating fan plate 82 can clean the mud, sand and gravel filtered on the surface of the filter plate 84 through the bristles 83. At the same time, the filter plate 84 is inclined toward the sewage outlet 6, and the setting of the fan plate 82 facilitates the cleaning of the mud, sand and gravel.
[0029] Specifically, Figures 2 to 3As shown, a cooling component 7 is provided on the right side of the top of the cooling box 1, and the cooling component 7 includes a cooling column 71, and the cooling column 71 is fixedly installed on the top of the cooling box 1 and is located on the right side of the first water pump 4 and the second water pump 5. The cooling column 71 is communicated with the inside of the cooling chamber 12, and an annular water groove 72 is provided inside the inner wall of the cooling column 71. A water supply pipe 41 is fixedly installed on the right side of the first water pump 4, and the right end of the water supply pipe 41 passes through the cooling column 71 and is fixedly connected to the water inlet at the upper end of the annular water groove 72. A water supply pipe 41 is also provided on the right side of the second water pump 5. Tube 41, and the water supply pipe 41 installed on the second water pump 5 is fixedly connected to the high-pressure nozzle 14, the water outlet at the lower end of the annular water tank 72 is communicated with the cooling chamber 12, a fan 75 is fixedly installed at the front end of the cooling column 71, an air inlet hole 73 is opened on the inner wall of the front end of the cooling column 71, and an exhaust hole 74 is opened on the inner wall of the rear end of the cooling column 71, a partition plate is arranged between the cooling chamber 12 and the coolant storage chamber 11, a reflux groove 13 is opened at the corner of the cooling chamber 12 and the partition plate, and the other end of the reflux groove 13 is communicated with the inside of the coolant storage chamber 11.
[0030] By adopting the above technical solution, when the drill bit enters the cooling chamber 12 through the cooling column 71, it will first be cooled to prevent the drill bit from being directly impacted by the coolant when entering the cooling chamber 12, resulting in a large hot and cold deviation and affecting the service life of the drill bit. The first water pump 4 draws the coolant in the coolant storage chamber 11 and supplies it into the annular water tank 72 inside the cooling column 71 through the water supply pipe 41. The coolant flows around the cooling column 71 through the annular water tank 72 and finally flows back into the cooling chamber 12. During this process, the temperature in the cooling column 71 is always maintained. At the same time, the fan 75 blows air into the cooling column 71. The air enters from the air inlet 73 and is discharged through the exhaust hole 74, further enhancing the cooling effect of the cooling component 7 on the drill bit. At the same time, this cooling method is relatively gentle, avoiding direct contact between the drill bit and the coolant when the drill bit is at high temperature. While ensuring the cooling effect of the drill bit, it can also avoid stress on the drill bit that reduces its service life.
[0031] Working principle: When in use, first inject coolant into the coolant storage chamber 11. When ready, start the first water pump 4, the second water pump 5 and the fan 75 at the same time, place the drill bit in the cooling column 71, and the drill bit is first cooled by the cooling component 7 and then placed in the cooling chamber 12. The high-pressure nozzle 14 sprays coolant to the drill bit to cool the drill bit. At the same time, the liquid and the mud, sand and gravel washed away flow to the fan plate 82 through the drainage plate 15. The fan plate 82 is forced to rotate through the rotating rod 81, and the mud, sand and gravel in the liquid are filtered by the filter plate 84, and the liquid refluxes. The mud, sand and gravel retained on the filter plate 84 are cleaned by the rotating fan plate 82 and the bristles 83, and finally discharged through the sewage outlet 6.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
