Description

Technical Field

[0001] The present invention relates to the technical field of oil-based rock cuttings transportation, and in particular to an oil-based rock cuttings transportation vehicle. Background Art

[0002] The large amount of waste oil-based mud cuttings generated in the exploitation of unconventional oil and gas reservoirs or complex formations generally contain benzene series, phenols, anthracenes, as well as heavy metals (including Ni, Cr, Ba, etc.), radioactive elements and other difficult-to-degrade toxic and harmful substances, and are accompanied by odor and toxicity. If not properly handled, they will cause great damage to the soil, water bodies and vegetation, bring huge pressure to the environment, and also lead to a waste of oil resources.

[0003] After the oil-based rock cuttings are produced, they need to be canned and transported to a designated factory for corresponding processing. However, especially in the winter when transporting oil-based rock cuttings, the temperature in some areas is relatively low, which increases the interaction force between the oil, water and solid particles in the oil-based rock cuttings, thereby increasing the viscosity of the oil-based rock cuttings and greatly reducing their fluidity. In this way, the oil-based rock cuttings stick to the inner wall of the tank and are not easy to fall off, and are not easy to flow out from the material port during unloading, resulting in congestion at the discharge port during unloading, greatly reducing the unloading efficiency. At the same time, after the oil-based rock cuttings solidify after being stuck to the inner wall of the tank for a long time, the internal volume of the tank is reduced. Summary of the Invention

[0004] The purpose of the present invention is to provide an oil-based rock cuttings transport vehicle, which is used to reduce the viscosity of oil-based rock cuttings during transportation in winter. The inner wall of the tank is not easy to stick to the oil-based rock cuttings, the internal volume of the tank is maintained, the discharge port will not be congested during unloading, and the unloading efficiency is improved.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] An oil-based rock cuttings transport vehicle comprises a transport vehicle, which is provided with a tank body for containing oil-based rock cuttings, the tank body being a cylindrical structure with a cavity inside, a rotary joint being provided on the top of the tank body, a pressure plate being provided slidingly provided in the cavity, the pressure plate dividing the cavity into a pressure chamber and a receiving chamber distributed up and down, one end of the rotary joint being connected to the exhaust pipe of the transport vehicle through a pipeline, and the other end being connected to a Y-shaped joint, one port of the Y-shaped joint being connected to the pressure chamber, a plurality of heat exchange air pipes being provided in the receiving chamber, the upper ends of the plurality of heat exchange air pipes passing through the pressure plate and then being connected to the other port of the Y-shaped joint, the lower ends of the plurality of heat exchange air pipes being connected to the exhaust port on the tank body, a feed port and a discharge port located below the feed port being provided on the side wall of the tank body, and a first valve being installed on both the feed port and the discharge port.

[0007] Due to the adoption of the above technical solution, on the basis of the existing transport vehicle for transporting oil-based rock cuttings, the tank body is designed into a cylindrical structure, and the cavity inside the tank body is divided into a pressure chamber and a receiving chamber by a pressure plate. The receiving chamber is used to store oil-based rock cuttings, and the oil-based rock cuttings are transported to the receiving chamber through the feed port and then discharged through the discharge port. The discharge port is located at the lower end of the tank body. In winter, the outside temperature drops. At this time, the high-temperature exhaust gas is transported to the Y-shaped joint through a pipeline. The Y-shaped joint transports the exhaust gas through one of the ports to each heat exchange pipe. Each heat exchange pipe conducts the heat of the exhaust gas to the oil-based rock cuttings on the outside, so that the temperature inside the oil-based rock cuttings increases, and the exhaust gas after heat exchange is discharged by the exhaust pipe. The exhaust gas is discharged from the air port, and the exhaust gas is continuously generated as the transport vehicle runs. Therefore, during the transportation process, the oil-based rock cuttings will always maintain a suitable temperature, so that the interaction force between the oil, water and solid particles inside it will be reduced, and the viscosity of the oil-based rock cuttings will be greatly reduced, and its fluidity will be better, so that the oil-based rock cuttings are not easy to stick to the inner wall of the tank, and thus during long-term transportation, the oil-based rock cuttings are not easy to stick, dry and clump on the inner wall of the tank, ensuring the effective volume of the tank. When unloading, there will be no congestion at the discharge port, and the oil-based rock cuttings will be easier to flow out, which improves the unloading efficiency and also recycles the automobile exhaust.

[0008] Furthermore, a second valve and a third valve are respectively installed on the two ports of the Y-shaped connector. The second valve is used to control the exhaust gas to enter the pressure chamber, and the third valve is used to control the exhaust gas to enter the heat exchange pipe.

[0009] Furthermore, the heat exchange air pipe is made of aluminum alloy, and the wall thickness of the heat exchange air pipe is 1-5 mm.

[0010] Furthermore, the upper portion of the heat exchange air pipe is a straight pipe, and the lower portion is a spiral pipe, and the height of the spiral pipe is 0.5-1m.

[0011] Furthermore, a rotating body is fixed at the bottom of the tank body, and a base fixed on the transport vehicle is provided below the rotating body. The bottom surface of the rotating body is a convex spherical surface, and the top surface of the base is provided with a concave spherical surface adapted to the convex spherical surface, and the rotating body is located in the concave spherical surface.

[0012] Furthermore, a rotating shaft is provided on the bottom surface of the rotating body, and a rotating groove is provided on the top surface of the base in the middle of the concave spherical surface, and the rotating shaft is located in the rotating groove.

[0013] Furthermore, a ring gear is provided on the circumference of the rotating body, a driving motor is fixed on the side wall of the base, and a driving gear meshing with the ring gear is provided on the output shaft of the driving motor.

[0014] Furthermore, the bottom surface of the tank body is a support block inclined toward the discharge port.

[0015] Furthermore, an air passage communicating with the lower end of the heat exchange air pipe is provided inside the support block, and an outlet of the air passage is communicated with the exhaust port.

[0016] Furthermore, an air duct is provided on the outside of the tank body, one end of the air duct is connected to the pressure chamber, and the other end is connected to the exhaust port. A fourth valve for controlling gas circulation is provided on the air duct, and an exhaust gas purifier is provided on the exhaust port.

[0017] The present invention has the beneficial effects:

[0018] 1. In the present invention, in winter, the outside temperature drops. At this time, the high-temperature exhaust gas is transported to the Y-shaped joint through a pipeline. The Y-shaped joint transports the exhaust gas through one of the ports to each heat exchange pipe. Each heat exchange pipe transfers the heat of the exhaust gas to the oil-based rock chips on the outside, so that the temperature inside the oil-based rock chips increases, and the exhaust gas after heat exchange is discharged from the exhaust port. The exhaust gas is continuously generated as the transport vehicle runs. Therefore, during the transportation process, the oil-based rock chips will always maintain a suitable temperature, so that the interaction force between the oil, water and solid particles inside the oil-based rock chips is reduced, and the viscosity of the oil-based rock chips will be greatly reduced, and its fluidity will be better, so that the oil-based rock chips are not easy to stick to the inner wall of the tank, and thus the oil-based rock chips are not easy to stick, dry and agglomerate on the inner wall of the tank during long-term transportation, thereby ensuring the effective volume of the tank. During unloading, the discharge port will not be congested, and the oil-based rock chips are easier to flow out, thereby improving the unloading efficiency and recycling the automobile exhaust gas.

[0019] 2. Since the heat of the exhaust gas has been partially utilized when it reaches the lower part of the accommodation chamber, the oil-based rock cuttings in the lower part of the accommodation chamber can exchange less heat and its viscosity is likely to increase. Therefore, the lower part of the heat exchange air pipe is divided into a spiral tube. This can slow down the exhaust gas discharge speed, allowing the oil-based rock cuttings in the lower part of the accommodation chamber to fully utilize the heat energy of the exhaust gas, ensuring that the viscosity of the oil-based rock cuttings in the lower part of the accommodation chamber can also be reduced.

[0020] 3. When unloading, the exhaust gas is injected into the pressure chamber to increase the air pressure in the pressure chamber. When the air pressure reaches a certain value, the air pressure in the pressure chamber will push the pressure plate downward, thereby squeezing the oil-based rock cuttings to a certain extent, and the oil-based rock cuttings can be discharged from the discharge port faster, making full use of the exhaust gas to improve the efficiency of unloading.

[0021] 4. A rotating body is provided at the bottom of the tank body, and the rotating body is rotatably arranged on the base. The driving motor drives the driving gear to rotate, and then the ring gear drives the rotating body to rotate. The upper tank body will also rotate with the rotating body, thereby driving the oil-based rock cuttings inside to rotate, so that the oil-based rock cuttings in the accommodating chamber can be evenly heated. The spiral tube at the lower part of the heat exchange air pipe on the rack forms a certain stirring effect, and the viscosity of the oil-based rock cuttings will be further reduced.

[0029] Example 1

[0030] An oil-based rock cuttings transport vehicle comprises a transport vehicle 16, which is provided with a tank body 1 for oil-based rock cuttings. The tank body 1 is a cylindrical structure with a cavity inside. A rotary joint 3 is provided on the top of the tank body 1, and a pressure plate 27 is provided slidingly in the cavity. The pressure plate 27 divides the cavity into a pressure chamber 6 and a receiving chamber 12 distributed upper and lower. One end of the rotary joint 3 is connected to the exhaust pipe of the transport vehicle 16 through a pipeline, and the other end is connected to a Y-shaped joint 4. One port of the Y-shaped joint 4 is connected to the pressure chamber 6. A plurality of heat exchange air pipes 11 are provided in the receiving chamber 12. The upper ends of the plurality of heat exchange air pipes 11 pass through the pressure plate 27 and are connected to the other port of the Y-shaped joint 4 after being collected. The lower ends of the plurality of heat exchange air pipes 11 are connected to the exhaust port 23 on the tank body 1. A feed port 9 and a discharge port 13 located below the feed port 9 are provided on the side wall of the tank body 1. A first valve 10 is installed on both the feed port 9 and the discharge port 13.

[0031] In this embodiment, based on the existing transport vehicle 16 for transporting oil-based cuttings, Figure 1 As shown, the tank body 1 is designed to be a cylindrical structure, and the cavity inside the tank body 1 is divided into a pressure chamber 6 and a receiving chamber 12 by a pressure plate 27. The receiving chamber 12 is used to store oil-based rock cuttings. After the first valve 10 of the feed port 9 is opened, the oil-based rock cuttings enter the feed port 9 and are transported to the receiving chamber 12. Finally, when unloading, the first valve 10 on the discharge port 13 is opened, and the oil-based rock cuttings are discharged through the discharge port 13. The pressure plate 27 is slidably connected to the heat exchange gas pipe 11, which facilitates the pressure plate 27 to slide up and down, and a sealing ring is embedded in the position where the pressure plate 27 contacts the heat exchange gas pipe 11 to prevent the oil-based rock cuttings from entering the pressure chamber 6. The installation of the rotary joint 3 is convenient for the subsequent rotation of the tank body 1. The port above the Y-shaped joint 4 is connected to the rotary joint 3, and the two ports below convey exhaust gas to the pressure chamber 6 and the heat exchange gas pipe 11 respectively. The multiple heat exchange gas pipes 11 can be distributed in a ring shape, or in a polygonal or triangular shape. Figure 3 As shown, the embodiment adopts a triangular distribution, which is as dispersed as possible to increase the contact area with the oil-based rock chips. In winter, the outside temperature drops. At this time, the high-temperature exhaust gas is transported to the Y-shaped joint 4 through a pipeline. The Y-shaped joint 4 transports the exhaust gas through one of its ports to each heat exchange pipe 11. Each heat exchange pipe 11 transfers the heat of the exhaust gas to the oil-based rock chips on the outside, so that the temperature inside the oil-based rock chips increases. The exhaust gas after heat exchange is discharged from the exhaust port 23. The exhaust gas is continuously generated as the transport vehicle 16 runs. Therefore, during transportation, the oil-based rock chips will always maintain a suitable temperature, so that the interaction force between the oil, water and solid particles inside the oil-based rock chips is reduced, and the viscosity of the oil-based rock chips will also be greatly reduced, and its fluidity will be better, so that the oil-based rock chips are not easy to stick to the inner wall of the tank body 1. Therefore, during long-term transportation, the oil-based rock chips are not easy to stick, dry and agglomerate on the inner wall of the tank body 1, ensuring the effective volume of the tank body 1 and not causing congestion at the discharge port 13. Figure 2 As shown, during unloading, high-temperature exhaust gas is transported into the pressure chamber 6 to increase the air pressure in the pressure chamber 6. When the air pressure reaches a certain value, the air pressure in the pressure chamber 6 will push the pressure plate 27 to move downward, thereby exerting a certain amount of pressure on the oil-based rock chips, and the oil-based rock chips can be discharged from the discharge port 13 more quickly, making full use of the exhaust gas to improve the efficiency of unloading, making it easier for the oil-based rock chips to flow out, and at the same time, the automobile exhaust gas can be recycled again.

[0032] Optionally, a second valve 2 and a third valve 5 are respectively installed on the two ports of the Y-shaped connector 4. The second valve 2 is used to control the exhaust gas from entering the pressure chamber 6, and the third valve 5 is used to control the exhaust gas from entering the heat exchange pipe 11.

[0033] Optionally, the heat exchange pipe 11 is made of aluminum alloy, and the wall thickness of the heat exchange pipe is 1-5 mm. Specifically, the aluminum alloy has good thermal conductivity and is more likely to transfer heat to the oil-based rock chips outside. A thickness of about 2 mm is more suitable, has a certain compressive resistance, and can also meet good thermal conductivity.

[0034] Example 2

[0035] Optionally, the upper portion of the heat exchange pipe 11 is a straight pipe, and the lower portion is a spiral pipe 25, and the height of the spiral pipe 25 is 0.5-1m. Figure 1 As shown, the upper portion of the heat exchange gas pipe 11 is a straight pipe, which facilitates the downward movement of the pressure plate 27 under the action of the air pressure in the pressure chamber 6, thereby quickly squeezing the oil-based rock cuttings to the outside and improving the oil-based rock cuttings unloading efficiency. At the same time, in order to allow the pressure plate 27 to reset automatically, a ring 8 can be welded on the straight pipe part of one of the heat exchange gas pipes 11 located in the middle of the pressure plate 27. A spring 7 is provided between the ring 8 and the pressure plate 27. In this way, when the pressure plate 27 squeezes the oil-based rock cuttings downward, it also squeezes the spring 7. After unloading is completed, the exhaust gas in the pressure chamber 6 is released, and the pressure plate 27 moves upward to its original position under the action of the spring 7. The spiral tube 25 at the lower part can first limit the pressure plate 27. Secondly, since the heat of the exhaust gas has been partially utilized when it reaches the lower part of the accommodating chamber 12, the heat that can be exchanged by the oil-based rock cuttings at the lower part of the accommodating chamber 12 is less, and its viscosity is easy to increase. Therefore, the lower part of the heat exchange gas pipe 11 is divided into a spiral tube 25, which can slow down the exhaust speed of the exhaust gas, allowing the oil-based rock cuttings at the lower part of the accommodating chamber 12 to fully utilize the heat energy of the exhaust gas, thereby ensuring that the viscosity of the oil-based rock cuttings at the lower part of the accommodating chamber 12 can also be reduced.

[0036] Example 3

[0037] Optionally, a rotating body 18 is fixed to the bottom of the tank body 1, and a base 30 fixed to the transport vehicle 16 is provided below the rotating body 18. The bottom surface of the rotating body 18 is a convex spherical surface, and the top surface of the base 30 is provided with a concave spherical surface adapted to the convex spherical surface, and the rotating body 18 is located in the concave spherical surface.

[0038] Optionally, a rotating shaft 19 is provided on the bottom surface of the rotating body 18, and a rotating groove 20 is provided on the top surface of the base 30 in the middle of the concave spherical surface, with the rotating shaft 19 located in the rotating groove 20. The cooperation between the rotating shaft 19 and the rotating groove 20 makes the rotating body 18 less likely to deviate. At the same time, in order to improve the flexibility of rotation, a bearing can be provided on the rotating shaft 19.

[0039] Optionally, a ring gear 17 is provided on the circumference of the rotating body 18 , a driving motor 15 is fixed on the side wall of the base 30 , and a driving gear 14 meshing with the ring gear 17 is provided on the output shaft of the driving motor 15 .

[0040] In this embodiment, Figure 1 As shown, the driving motor 15 drives the driving gear 14 to rotate, and then drives the rotating body 18 to rotate through the ring gear 17. The upper tank body 1 will also rotate along with the rotating body 18, thereby driving the oil-based rock cuttings inside to rotate, so that the oil-based rock cuttings in the accommodating chamber 12 can be evenly heated. The spiral tube 25 at the lower part of the heat exchange air pipe 11 on the rack forms a certain stirring effect, and the viscosity of the oil-based rock cuttings will be further reduced.

[0041] Example 4

[0042] Optionally, the bottom surface of the tank body 1 is a support block 28 inclined toward the discharge port 13. Specifically, Figure 1 As shown, the bottom surface of the tank body 1 is integrally formed or welded with a support block 28, and the top view structure of the support block 28 is still circular, and the top surface of the support block 28 is an inclined surface inclined toward the discharge port 13, which improves the efficiency of unloading. At the same time, when there are fewer oil-based rock chips inside, the oil-based rock chips can be collected to the discharge port 13, so that the oil-based rock chips in the tank body 1 can be basically completely discharged.

[0043] Example 5

[0044] Optionally, an air passage 22 communicating with the lower end of the heat exchange air pipe 11 is provided inside the support block 28 , and an outlet of the air passage 22 is communicated with the exhaust port 23 .

[0045] Optionally, an air duct 29 is provided on the outside of the tank body 1, one end of the air duct 29 is connected to the pressure chamber 6, and the other end is connected to the exhaust port 23. A fourth valve 26 for controlling gas circulation is provided on the air duct 29, and an exhaust gas purifier 24 is provided on the exhaust port 23.

[0046] In this embodiment, a flow passage 22 for exhaust gas discharge is provided inside the support block 28, and the outlets of each heat exchange air pipe 11 are all converged into a connecting pipe 21, and the connecting pipe 21 is connected to the flow passage 22. The connecting pipe 21 and the support block 28 are welded to prevent oil-based rock cuttings from entering the flow passage 22. The air guide pipe 29 can transport the exhaust gas in the pressure chamber 6 to the exhaust port 23 to discharge the exhaust gas after work, so as to facilitate the pressure plate 27 to return to its original position. An exhaust purifier 24 is installed at the exhaust port 23 to purify the exhaust gas and reduce environmental pollution.

[0047] The working principle of the present invention is as follows: during the transportation of oil-based rock chips, when the outside temperature is low, the third valve 5 can be opened to allow the high-temperature exhaust gas to enter each heat exchange air pipe 11. Each heat exchange air pipe 11 transfers the heat of the exhaust gas to the oil-based rock chips on the outside, so that the temperature inside the oil-based rock chips increases, and the exhaust gas after heat exchange is discharged from the exhaust port 23. The exhaust gas is continuously generated as the transport vehicle 16 runs. Therefore, during the transportation process, the oil-based rock chips will always maintain a suitable temperature, so that the interaction force between the oil, water and solid particles inside it is reduced, and the viscosity of the oil-based rock chips will also be greatly reduced, and its fluidity will also be better, so that the oil-based rock chips are not easy to stick to the inner wall of the tank body 1, and thus during long-term transportation, the oil-based rock chips are not easy to stick, dry and agglomerate on the inner wall of the tank body 1, ensuring the effective volume of the tank body 1 and not causing congestion at the discharge port 13. At the same time, the driving motor 15 drives the rotating body 18 to rotate, and the upper tank body 1 will also rotate along with the rotating body 18, thereby driving the oil-based rock chips inside to rotate, so that the oil-based rock chips in the accommodating chamber 12 can be evenly heated, and the spiral tube 25 at the lower part of the heat exchange air pipe 11 on the rack forms a certain stirring effect, which will further reduce the viscosity of the oil-based rock chips. During unloading, the third valve 5 can be closed, the second valve 2 can be opened, and the driving motor 15 can be stopped to transport high-temperature exhaust gas into the pressure chamber 6 to increase the air pressure in the pressure chamber 6. When the air pressure reaches a certain value, the air pressure in the pressure chamber 6 will push the pressure plate 27 to move downward, thereby exerting a certain amount of pressure on the oil-based rock cuttings, and the oil-based rock cuttings can be discharged from the discharge port 13 faster. When the pressure plate 27 reaches above the spiral tube 25, the second valve 2 is closed, and the fourth valve 26 is opened to discharge the exhaust gas in the pressure chamber 6. The pressure plate 27 moves upward under the action of the spring 7. In this way, the pressure plate 27 can repeatedly exert an extrusion force on the oil-based rock cuttings, which can greatly improve the unloading efficiency and make full use of the exhaust gas to improve the unloading efficiency. The oil-based rock cuttings are more likely to flow out, and the automobile exhaust gas can also be further recycled.

[0048] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Based on the technical essence of the present invention and within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present invention.
