Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mud cooling equipment for petroleum drilling engineering, in particular to a mud cooling equipment for petroleum drilling engineering. BACKGROUND

[0002] When the mud is cooled, the high-temperature mud needs to be sent into the device, enter the filler layer, and then be sprayed to make the water film appear on the surface of the high-temperature mud and the high-temperature mud slowly drip from the holes in the filler layer, and then be cooled with the subsequent cold air, and finally be pumped out by the pump body.

[0003] When the mud enters the filler layer, the high-temperature mud has already begun to drip, which will make part of the high-temperature mud drip downward without being sprayed or without the water film appearing on the surface of the high-temperature mud, and be pumped out by the bottom pump body and pass through the inside of the pump body. At this time, the high-temperature mud will contact the sealing element and the outer wall of the impeller, and the high temperature will cause the dissolved gas in the mud to precipitate to form bubbles. When the bubbles burst, the impact force generated will damage the sealing element and the surface of the impeller of the pump, causing leakage, vibration and noise, and even directly causing the pump body to be stuck.

Preferably, the telescopic assembly comprises a spring I fixedly connected at the outer wall of the positioning column, the inner wall of the positioning column being rotatably connected with a rotating block, the inner wall of the rotating block being slidingly connected with a deceleration block, and a tooth groove being fixedly connected at the inner wall of the through hole of the box body.

[0011] Preferably, the motion assembly comprises a plurality of fixed rods fixedly connected at the outer wall of the box body, a push rod fixedly connected at the outer wall of the fixed rod, a plurality of fixed blocks fixedly connected at the outer wall of the slope plate, and the inner wall of the fixed block being slidingly connected with the outer wall of the push rod. Preferably, the motion assembly comprises a plurality of fixed rods fixedly connected at the outer wall of the box body, a push rod fixedly connected at the outer wall of the fixed rod, a plurality of fixed blocks fixedly connected at the outer wall of the slope plate, and the inner wall of the fixed block being slidingly connected with the outer wall of the push rod.

[0012] Preferably, the thrust assembly comprises a rotating rod fixedly connected at the inner wall of the push rod, a rotating block rotatably connected at the inner wall of the fixed block, the end of the rotating rod away from the push rod being rotatably connected with the rotating block, and a connecting rod rotatably connected at the outer wall of the rotating block.

[0013] Preferably, the cleaning assembly comprises a spiral groove formed at the inner wall of the mud dripping hole, a rotating scraper slidingly connected at the outer wall of the spiral groove, an isolation column rotatably connected at the inner wall of the rotating scraper, an isolation plate fixedly connected at the outer wall of the isolation column, and the end of the connecting rod away from the rotating block being rotatably connected with the isolation plate. Preferably, the cleaning assembly comprises a spiral groove formed at the inner wall of the mud dripping hole, a rotating scraper slidingly connected at the outer wall of the spiral groove, an isolation column rotatably connected at the inner wall of the rotating scraper, an isolation plate fixedly connected at the outer wall of the isolation column, and the end of the connecting rod away from the rotating block being rotatably connected with the isolation plate.

[0014] The present application has the following advantages: (1) When the mud is evenly distributed on the surface of the inclined plate, it will reach the critical value of several springs contraction. As the mud continues to enter, it forces several connecting columns and positioning columns to move downward and squeeze the springs. When the deceleration block moving downward contacts the tooth groove, it will flip upward. At this time, the inclined plate will move downward. When the inclined plate is downward, the partition is no longer in contact with the baffle and will open the gap. The cold air inside will be discharged to the outside by the fan above. This will cause the cold air entering to pass through the gap of the partition and flow to the outside. At the same time, several fixed blocks fixed to the bottom of the inclined plate will move downward, which will push the rotating rod. As the rotating block rotates, it pulls the isolation plate downwards, opening the drip holes and allowing the slurry to drip slowly down through the isolation plate. The water film formed by the slurry on the inclined plate comes into full contact with the cold air, transferring heat from the slurry to the air and cooling the slurry. In this way, the slurry is evenly distributed on the surface of the inclined plate, forming a uniform water film, increasing the heat exchange area, and preventing the hot slurry from dripping directly through the holes to the bottom. This would prevent a large amount of slurry from being reused without being cooled, leading to cavitation and pump leakage when it enters the pump body later.

[0015] (2) The present invention seals the drip hole with a partition plate, so that the mud is evenly distributed on the surface of the inclined plate. The pressure of the mud causes the inclined plate to drop, which opens the partition plate at the drip hole and drips the mud. In this way, the mud drips evenly to the bottom, and the mud flows into the pump body in a continuous flow. This will make the subsequent water pump less likely to frequently deal with material shortages and dry running or instantaneous full load, making the subsequent operation more stable and greatly reducing the wear of the motor and pump shaft.

[0016] (3) In this invention, the water in the high-temperature mud that has been piled in the drip hole for a long time will partially evaporate, causing some clay particles to be deposited on the inner wall of the pore. If not treated in time, they will form hard mud cakes or lumps, eventually blocking the pores. This will cause the mud to flow out only from the unblocked pores and form a biased flow, further aggravating the accumulation and forming lumps. When the isolation plate is pulled by the connecting rod, the rotating scraper will rotate along the spiral groove. At this time, the rotating scraper will scrape off the mud and sand adsorbed on the inner wall of the drip hole, preventing the drip hole from becoming blocked later.

[0017] (4) When the mud in the mud pipe no longer enters, as the mud on the inclined plate decreases, the weight of the inclined plate and the baffle is reduced, and the positioning columns on both sides are moved upward by the elastic potential energy of the spring. At this time, the deceleration block at the bottom will contact the tooth groove when it moves upward, causing the deceleration block to contract inward. When it passes through a tooth groove, the deceleration block will pop out again through the spring inside the rotating block and contact the next tooth groove. In this way, the speed of the inclined plate rising is slowed down, so that the mud that is still on the inner wall of the drip hole drips to the bottom, preventing the remaining mud from being left in the drip hole and blocking the drip hole when the isolation plate is closed.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1, please refer to Figure 1 - Figure 4 The present invention is a mud cooling device for oil drilling engineering, including an external mechanism 1, the external mechanism 1 further including a box 16, a mud pipe 12 fixedly connected to the outer wall of the box 16, a cold air pipe 13 fixedly connected to the outer wall of the box 16, a water inlet pipe 14 fixedly connected to the outer wall of the box 16, a fan 17 fixedly connected to the top of the box 16, and a mud suction pipe 15 fixedly connected to the outer wall of the box 16. Fixing mechanism 2 is slidably connected to the inner wall of the box 16 and is used to collect the incoming mud. Telescopic mechanism 3 is fixedly connected to the inner wall of the box 16 to slow down the falling speed of mud. The cleaning mechanism 4 is fixedly connected to the inner wall of the housing 16 to isolate cold air and mud.

[0023] Fixed mechanism 2 includes: Sliding component 21 is slidably connected to the inner wall of housing 16; The deceleration assembly 22 is slidably connected to the inner wall of the housing 16. Before starting work, the operator connects the external gear pump to the mud pipe 12. When starting work, the operator first sends cold air into the device and continues for two to three minutes to make the cold air evenly distributed below the inclined plate 211. Then the gear pump is started to transport the mud from the mud pipe 12 to the surface of the inclined plate 211. At this time, water is transported from the water inlet pipe 14 and sprayed onto the surface of the mud through the nozzle on the outer wall of the water inlet pipe 14, so that the surface of the mud is covered with a layer of water film.

[0024] Example 2, please refer to Figure 2 - Figure 9 This invention relates to a mud cooling device for oil drilling engineering. Based on Example 1, the telescopic mechanism 3 includes: Telescopic component 31 is fixedly connected to the outer wall of deceleration component 22; The motion component 32 is fixedly connected to the inner wall of the box 16. When the mud is evenly distributed on the surface of the inclined plate 211, it will reach the critical value of the contraction of several springs 311. As more mud enters, several connecting columns 221 and positioning columns 222 will move downward and squeeze the springs 311.

[0025] Cleaning mechanism 4 includes: Thrust assembly 41 is rotatably connected to the outer wall of motion assembly 32; The cleaning component 42 is fixedly connected to the outer wall of the thrust component 41. When the inclined plate 211 rises, the fixed block 323 also rises. When the fixed block 323 rises, the rotating rod 411 pushes the rotating block 412 to rotate in the opposite direction again, which will cause the isolation plate 421 to close the gap.

[0026] The sliding assembly 21 includes a baffle 213 slidably connected to the inner wall of the housing 16. An inclined plate 211 is fixedly connected to the inner wall of the baffle 213. Several drip holes 212 are opened on the outer wall of the inclined plate 211. When the inclined plate 211 is downward, the partition 224 is no longer in contact with the baffle 213 and will open a gap. The cold air inside is discharged to the outside by the fan 17 above. This will cause the cold air entering to pass through the gap of the partition 224 and flow to the outside.

[0027] The deceleration assembly 22 includes several connecting posts 221 fixedly connected to the outer wall of the baffle 213, positioning posts 222 fixedly connected to the outer wall of the several connecting posts 221, a fixing frame 223 fixedly connected to the inner wall of the through hole of the housing 16, and positioning posts 222 slidably connected to the inner wall of the fixing frame 223; a partition 224 is fixedly connected to the inner wall of the housing 16. The mud enters the baffle 213 from the mud pipe 12. As the mud gradually spreads on the surface of the inclined plate 211, the connecting column 221 and the positioning column 222 slide on the fixing frame 223 at the inner wall of the through hole of the housing 16. The partition 224 and the baffle 213 are initially in contact with each other. The mud is evenly distributed on the surface of the inclined plate 211. The pressure of the mud causes the inclined plate 211 to drop, which opens the partition plate 421 at the mud dripping hole 212 and drips the mud. In this way, the mud drips evenly to the bottom, and the mud flows into the pump body in a continuous flow. This will make the subsequent water pump less likely to frequently run dry due to material shortage or instantaneous full load, making the subsequent operation more stable and greatly reducing the wear of the motor and pump shaft.

[0028] The telescopic assembly 31 includes a spring 311 fixedly connected to the outer wall of the positioning post 222. The end of the spring 311 away from the positioning post 222 is fixedly connected to the inner wall of the through hole of the housing 16. A rotating block 312 is rotatably connected to the inner wall of the positioning post 222. A deceleration block 313 is slidably connected to the inner wall of the rotating block 312. A toothed groove 314 is fixedly connected to the inner wall of the through hole of the housing 16. The spring inside the rotating block 312 is fixedly connected to the deceleration block 313. The positioning post 222 has a protrusion below the rotating block 312 to fix the rotating block 312 and prevent it from rotating downward. The deceleration assembly 22 and the telescopic assembly 31 are distributed symmetrically on the front and back of 16.

[0029] The motion component 32 includes several fixed rods 321 fixedly connected to the outer wall of the housing 16. A push rod 322 is fixedly connected to the outer wall of the fixed rods 321. Several fixed blocks 323 are fixedly connected to the outer wall of the inclined plate 211. The inner wall of the fixed block 323 is slidably connected to the outer wall of the push rod 322. Each dripping hole 212 has a fixing block 323 and a push rod 322 next to its bottom. The fixing rod 321 is located next to each row of dripping holes 212. A torsion spring is installed at the intersection of the push rod 323 and the rotating block 412.

[0030] The thrust assembly 41 includes a rotating rod 411 fixedly connected to the inner wall of the push rod 322, a rotating block 412 rotatably connected to the inner wall of the fixed block 323, a rotating block 412 rotatably connected to the end of the rotating rod 411 away from the push rod 322, and a connecting rod 413 rotatably connected to the outer wall of the rotating block 412. The rotating rod 411 pushes the rotating block 412 to rotate. When the rotating block 412 rotates, it pulls the isolation plate 421 downward. At this time, the mud dripping hole 212 will open, allowing the mud to drip slowly downward through the isolation plate 421.

[0031] The cleaning component 42 includes a spiral groove 423 formed on the inner wall of the dripping hole 212, a rotating scraper 424 slidably connected to the outer wall of the spiral groove 423, an isolation column 422 rotatably connected to the inner wall of the rotating scraper 424, an isolation plate 421 fixedly connected to the outer wall of the isolation column 422, and an isolation plate 421 rotatably connected to the end of the connecting rod 413 away from the rotating block 412. Each drip hole 212 contains a thrust assembly 41 and a cleaning assembly 42. A rotating scraper 424 is slidably connected to a spiral groove 423 on one side. When the isolation plate 421 is pulled by the connecting rod 413, the rotating scraper 424 will rotate along the spiral groove 423. At this time, the rotating scraper 424 will scrape off the mud and sand adsorbed on the inner wall of the drip hole 212, preventing the drip hole 212 from becoming blocked later.

[0032] One specific application of this embodiment is as follows: Before starting work, the operator connects the external gear pump to the mud pipe 12. When starting work, the operator first sends cold air into the device and continues for two to three minutes to make the cold air evenly distributed below the inclined plate 211. Then, the gear pump is started to transport the mud from the mud pipe 12 to the surface of the inclined plate 211. At this time, water is transported from the water inlet pipe 14 and sprayed onto the surface of the mud through the nozzle on the outer wall of the water inlet pipe 14, so that the surface of the mud is covered with a layer of water film.

[0033] When the mud is evenly distributed on the surface of the inclined plate 211, it will reach the critical value of the contraction of several springs 311. As more mud enters, several connecting posts 221 and positioning posts 222 will move downward and squeeze the springs 311. When the downward-moving deceleration block 313 contacts the tooth groove 314, it will flip upward. At this time, the inclined plate 211 will move downward. When the inclined plate 211 moves downward, the partition 224 will no longer be in contact with the baffle 213 and will open the gap. The cold air inside will be exhausted to the outside by the fan 17 above. This will cause the cold air entering to flow out through the gap of the partition 224. At the same time, several fixed parts at the bottom of the inclined plate 211 will... Block 323 will move downwards, causing the rotating rod 411 to push the rotating block 412 to rotate. When the rotating block 412 rotates, it will pull the isolation plate 421 downwards. At this time, the dripping hole 212 will open, allowing the mud to drip slowly downwards through the isolation plate 421. The water film formed by the mud at the inclined plate 211 will come into full contact with the cold air, allowing heat to be transferred from the mud to the air, thus cooling the mud. In this way, the mud is evenly distributed on the surface of the inclined plate 211, allowing the mud to form a uniform water film, increasing the heat exchange area, and preventing the hot mud that has just entered from dripping directly through the holes to the bottom. This would allow a large amount of mud to be reused directly without being cooled.

[0034] By sealing the drip hole 212 with the isolation plate 421, the mud is evenly distributed on the surface of the inclined plate 211. The pressure of the mud causes the inclined plate 211 to drop, which opens the isolation plate 421 at the drip hole 212, allowing the mud to drip down. In this way, the mud drips evenly to the bottom, allowing the mud to flow into the pump body in a continuous flow. This will prevent the subsequent water pump from frequently dealing with material shortages and dry running or instantaneous full load, making the subsequent operation more stable and significantly reducing the wear and tear on the motor and pump shaft.

[0035] Because some of the moisture in the high-temperature mud that has been piled up in the drip hole 212 for a long time will evaporate, some clay particles will be deposited on the inner wall of the pores. If not treated in time, they will form hard mud cakes or lumps, eventually blocking the pores. This will cause the mud to flow out only from the unblocked pores and form a biased flow, further aggravating the accumulation and forming lumps. When the isolation plate 421 is pulled by the connecting rod 413, the rotating scraper 424 will rotate along the spiral groove 423. At this time, the rotating scraper 424 will scrape off the mud and sand adsorbed on the inner wall of the drip hole 212, preventing the drip hole 212 from becoming blocked later.

[0036] When the mud in the mud pipe 12 stops entering, as the mud on the inclined plate 211 decreases, the weight of the inclined plate 211 and the baffle 213 is reduced, causing the positioning posts 222 on both sides to move upward by the elastic potential energy of the spring 311. At this time, the deceleration block 313 at the bottom will contact the tooth groove 314 when it moves upward, causing the deceleration block 313 to retract inward. When it passes through a tooth groove 314, the deceleration block 313 will be ejected again by the spring inside the rotating block 312 and contact the next tooth groove 314. In this way, the upward speed of the inclined plate 211 is slowed down, so that the mud still on the inner wall of the drip hole 212 drips to the bottom, preventing any remaining mud from remaining in the drip hole 212 when the isolation plate 421 is closed.

[0037] When the inclined plate 211 rises, the fixed block 323 also rises. When the fixed block 323 rises, it will cause the rotating rod 411 to push the rotating block 412 to rotate in the opposite direction again, which will cause the isolation plate 421 to close the gap.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
