Description

Technical Field

[0001] The present invention relates to the field of water-based drilling, and particularly to a recycling type water-based drilling waste treatment device. Background Art

[0002] Recycling type water-based drilling plays an important role in oil and gas exploitation. Compared with oil-based drilling fluids, water-based drilling fluids have obvious advantages in terms of environmental protection. However, if the waste generated after the exploitation of recycling type water-based drilling is directly discharged without treatment, it will cause pollution to the environment. Therefore, it is necessary to treat these wastes. These wastes generally contain oily components such as cuttings, clay, lubricants, and asphalt-like organic substances. Therefore, when treating the wastes, a solid-liquid separation device is generally used for solid-liquid separation first. However, the separated liquid still contains oily components after solid-liquid separation. Therefore, it is also necessary to perform oil-water separation treatment on the separated waste liquid, which increases the waste treatment process and reduces the waste treatment efficiency. Therefore, a recycling type water-based drilling waste treatment device is needed to solve the problem that the existing recycling type water-based drilling waste treatment device cannot treat the oily components in the waste liquid during solid-liquid separation. Summary of the Invention

A transmission mechanism is fixedly connected to the top of the ring. The transmission mechanism is connected to the driving mechanism. The transmission mechanism is used to control the ring to drive the oil-water separation mechanism and the closing mechanism to rotate respectively when rotating around the treatment cylinder.

[0005] Further, the driving mechanism includes a driving motor and a bevel gear ring. The driving motor is fixedly connected to the top of the treatment cylinder. The output end of the driving motor is fixedly connected to a driving bevel gear. The bevel gear ring is rotatably connected to the radial surface of the feed pipe. The driving bevel gear meshes with the bevel gear ring. A plurality of connecting rods are fixedly connected to the bottom of the bevel gear ring. The bottom ends of the plurality of connecting rods are respectively fixedly connected to the upper surface of the support plate.

[0006] Further, the oil-water separation mechanism includes a connecting plate.

[0007] Further, the closing mechanism includes a plurality of sealing plates. The plurality of sealing plates correspond to the drain ports respectively. The plurality of sealing plates are respectively connected to the inner side chute of the outlet groove. A connecting shaft is longitudinally fixedly connected to the outside of the plurality of sealing plates. The connecting shafts are respectively fixedly connected to the lower surface of the ring.

[0008] Further, the transmission mechanism includes a first transmission shaft and a second transmission shaft.

[0013] The working principle and usage principle of the present invention are as follows: The device inputs the water-based drilling waste that needs solid-liquid separation into the separation cylinder through the feed pipe. The water-based drilling waste input into the separation cylinder generates centrifugal force through the rotation of the support plate controlled by the driving mechanism. The waste is solid-liquid separated by the centrifugal force. The separated waste liquid flows into the water storage tank through the separation chamber. After being controlled by the closing mechanism, a certain amount of waste liquid is stored in the water storage tank. Subsequently, the oil-water separation mechanism is driven to rotate circumferentially in the water storage tank by the control of the driving mechanism and the transmission mechanism. The circumferentially rotating oil-water separation mechanism can separate and filter the oil components floating on the upper layer of the waste liquid. The waste liquid after oil-water separation flows into the water outlet groove through the drain port, and then the treated waste liquid is discharged through the water outlet at the front end of the water outlet groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Compared with the prior art, the present invention conveniently separates solid and liquid in the water-based drilling waste through the centrifugal force generated by controlling the rotation of the support plate by the driving mechanism, improves the treatment effect and efficiency of the water-based drilling waste, and facilitates the subsequent treatment of the water-based drilling waste.

[0015] 2. Compared with the prior art, the present invention facilitates the control of the rotation of the ring by connecting the transmission mechanism and the driving mechanism, which in turn facilitates the control of the rotation of the closing mechanism and the oil-water separation mechanism. As a result, it is convenient to separate the oil floating on the upper surface of the waste liquid after solid-liquid separation, improving the effect and efficiency of the treatment of the separated waste liquid. This avoids the need to increase the waste liquid treatment process due to the presence of oil in the waste liquid, thereby enhancing the waste liquid treatment efficiency.

[0016] 3. Compared with the prior art, the present invention can synchronously control the rotation of the support plate, the closing mechanism, and the oil-water separation mechanism through the driving mechanism, improving the energy utilization rate of the driving motor and reducing the costs of enterprises.

DETAILED DESCRIPTION OF THE INVENTION

[0023] To make the technical means, creative features, achieved purposes and effects realized by the embodiments of the present application easy to understand, the embodiments of the present application will be further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0024] According to Figures 1 to 5 As shown, a recycling type water-based drilling waste treatment device includes a treatment cylinder 1. A separation cavity 3 is provided in the treatment cylinder 1. A feed pipe 81 is fixedly connected to the top of the separation cavity 3. A support mechanism 2 is fixedly connected to the bottom of the treatment cylinder 1. A support plate 9 is rotatably connected to the bottom of the separation cavity 3. A plurality of annularly distributed water leakage holes 92 are formed through the surface of the support plate 9. A separation cylinder 8 with an opening at the top is fixedly connected to the top inside the separation cavity 3. The bottom of the separation cylinder 8 is rotatably connected to the upper surface of the support plate 9. A discharge pipe 91 embedded in the bottom of the treatment cylinder 1 is rotatably connected to the bottom of the support plate 9. A driving mechanism 14 for driving the support plate 9 to rotate is fixedly connected to the top of the treatment cylinder 1. The driving mechanism 14 is fixedly connected to the upper surface of the support plate 9. A water diversion groove 4 and a water storage tank 5 that communicate with each other are provided around the bottom of the separation cavity 3. The water diversion groove 4 is used to divert the separated liquid waste into the water storage tank 5. The water storage tank 5 is used to temporarily store the liquid waste. A plurality of oil-water separation mechanisms are rotatably arranged in the water storage tank 5. A water outlet groove 7 is provided in the treatment cylinder 1 outside the water storage tank 5. A water outlet 71 is provided at the front end of the water outlet groove 7. A plurality of drain ports 6 for communicating with the water storage tank 5 are provided inside the water outlet groove 7. A plurality of closing mechanisms for closing the drain ports 6 are respectively slidably connected to the outside of the drain ports 6. The upper ends of the closing mechanisms and the oil-water separation mechanisms respectively pass through the treatment cylinder 1 and are fixedly connected to a ring 10. A transmission mechanism 11 is fixedly connected to the top of the ring 10. The transmission mechanism 11 is connected to the driving mechanism 14. The transmission mechanism 11 is used to control the ring 10 to drive the oil-water separation mechanism and the closing mechanism to rotate around the treatment cylinder 1 when rotating.

[0025] In specific implementation, a separation chamber 3 and a water storage tank 5 are arranged in the treatment cylinder 1. The separation chamber 3 is used for solid-liquid separation of waste, and the water storage tank 5 is used to temporarily store the waste liquid after separation. The height of the stored waste liquid is matched with the height of the oil-water separation mechanism, which is convenient for the oil-water separation mechanism to perform oil-water separation on the upper waste. A circular water outlet tank 7 is fixedly connected to the outer periphery of the treatment cylinder 1. The water outlet tank 7 is communicated with the water storage tank 5 through a drain port 6. During use, first, the driving mechanism 14 is used to control the axial rotation of the support plate 9. The rotating support plate 9 causes the waste put into the separation cylinder 8 to generate a centrifugal force and rotate and move towards the inner wall of the separation cylinder 8. When the waste rotates and moves in the separation cylinder 8, the centrifugal force generated can cause the waste liquid to flow through the separation groove of the separation cylinder 8 towards the inner wall of the separation chamber 3, and then flow downward through the water leakage holes 92 formed on the surface of the support plate 9 and be stored in the water storage tank 5. At the same time, the solid waste is temporarily retained inside the separation cylinder 8. When the separated waste liquid is stored in the water storage tank 5, the driving mechanism 14 is used to control the operation of the transmission mechanism 11 to realize the rotation of the control ring 10. The rotating ring 10 drives the bottom closing mechanism and the oil-water separation mechanism to rotate respectively. The rotation of the closing mechanism can realize the reciprocating opening and closing of multiple drain ports 6. The reciprocating opening and closing of the drain ports 6 can cause the waste liquid to be discharged outward while being stored in the water storage tank 5. Because when the closing component closes the drain port 6, part of the waste liquid will be temporarily stored in the water storage tank 5. At the same time, due to the different densities of the water and oil components in the waste liquid, the waste liquid with oil components will float above the waste liquid. At this time, the oil-water separation mechanism rotating in the water storage tank 5 is used to filter the waste liquid with oil components floating on the surface of the upper waste liquid. The drain port 6 can discharge the waste liquid without oil components located in the lower layer through the drain port 6 into the water outlet tank 7. A slope can be arranged on the ground of the water outlet tank 7, and the water outlet 71 is located at the lowest point of the slope. The treated waste liquid can be discharged through the slope and the water outlet 71 of the water outlet tank 7.

[0026] Further, the driving mechanism 14 includes a driving motor 141 and a bevel gear ring 143. The driving motor 141 is fixedly connected to the top of the treatment cylinder 1. The output end of the driving motor 141 is fixedly connected with a driving bevel gear 142. The bevel gear ring 143 is rotatably connected to the radial surface of the feed pipe 81. The driving bevel gear 142 is meshed with the bevel gear ring 143. The bottom of the bevel gear ring 143 is fixedly connected with a plurality of connecting rods 144, and the bottom ends of the plurality of connecting rods 144 are respectively fixedly connected to the upper surface of the support plate 9.

[0027] In specific implementation, the conical gear ring 143 is fixedly connected to the radial surface of the feed pipe 81, and the driving motor 141 is fixedly installed on the upper surface of the processing cylinder 1. By the meshing of the driving bevel gear 142 at the output end of the driving motor 141 with the conical gear ring 143, the rotation of the conical gear ring 143 is controlled. The rotating conical gear ring 143 drives the four connecting rods 144 fixedly connected to the lower end surface to rotate synchronously in a circular motion. The four connecting rods 144 rotating in a circular motion drive the support plate 9 to rotate by being fixedly connected to the upper surface of the support plate 9. The rotating support plate 9 drives the waste to rotate to generate a centrifugal effect, which is beneficial for separating the solid and liquid of the waste by centrifugal force. The separated waste liquid flows through the separation groove on the surface of the separation cylinder 8 to the inner wall of the separation chamber 3, and then flows downward through the water leakage holes 92 opened on the surface of the support plate 9 into the water storage tank 5 for collection. The upper end of the discharge pipe 91 is rotatably connected to the lower surface of the support plate 9, and at the same time, the discharge pipe 91 is fixedly embedded in the bottom of the processing cylinder 1. The upper end of the discharge pipe 91 is communicated with the separation chamber 3, and the lower end of the discharge pipe 91 extends to the outside of the processing cylinder 1. The solid waste remaining in the separation cylinder 8 and the support plate 9 is discharged outward through the discharge pipe 91.

[0028] Further, the oil-water separation mechanism includes a connecting plate 13. The top of the connecting plate 13 passes through the processing cylinder 1 and is fixedly connected to the lower surface of the ring 10. The bottom of the connecting plate 13 is fixedly connected with an oil filtering box 17. The oil filtering box 17 is located in the water storage tank 5, and a plurality of oil filtering plates 18 are fixedly connected in the oil filtering box 17.

[0029] In specific implementation, a first annular groove is formed on the surface of the processing cylinder 1. The connecting plate 13 passes through the first annular groove and is fixedly connected to the oil filtering box 17 located in the water storage tank 5. The top of the connecting plate 13 is fixedly connected to the bottom of the ring 10. When the transmission mechanism 11 controls the ring 10 to rotate, the rotation of the ring 10 drives the connecting plate 13 to rotate in a circular motion. The connecting plate 13 rotating in a circular motion drives the oil filtering box 17 at its bottom to rotate in a circular motion in the water storage tank 5. The rotating oil filtering box 17 can filter the oil floating above the waste liquid, which is convenient for filtering the oil in the waste liquid.

[0030] Further, the closing mechanism includes a plurality of sealing plates 16. The plurality of sealing plates 16 correspond to the drain openings 6 respectively. The plurality of sealing plates 16 are respectively connected to the inner side sliding grooves of the water outlet tank 7. Longitudinal connecting shafts 12 are fixedly connected to the outer sides of the plurality of sealing plates 16, and the connecting shafts 12 are respectively fixedly connected to the lower surface of the ring 10.

[0031] In specific implementation, the number of the sealing plates 16 is the same as that of the drain ports 6. During use, the rotation of the ring 10 drives the connecting shaft 12 to perform a circular motion. The plurality of connecting shafts 12 performing circular rotation respectively drive the sealing plates 16 at their bottom ends to rotate circumferentially inside the water outlet tank 7. The rotating sealing plates 16 can continuously open and close the plurality of drain ports 6. Due to the circular motion of the sealing plates 16, the drain ports 6 can intermittently discharge the water in the water storage tank 5 into the water outlet tank 7. Therefore, a certain amount of waste liquid can be stored in the water storage tank 5. By storing a certain amount of waste liquid, it is convenient for the oil filter box 17 to filter and collect the oil on the upper part of the waste liquid stored in the water storage tank 5, realizing the separation of oil and water in the waste liquid and improving the treatment efficiency of the waste liquid.

[0032] Further, the transmission mechanism 11 includes a first transmission shaft 111 and a second transmission shaft 114. The first transmission shaft 111 is horizontally rotatably connected to the top of the treatment cylinder 1, and the second transmission shaft 114 is longitudinally rotatably connected to one side of the treatment cylinder 1. Two ends of the first transmission shaft 111 are respectively fixedly connected with a driven bevel gear 112 and a first driving bevel gear 113. The driven bevel gear 112 meshes with the conical surface gear ring 143. The top and bottom of the second transmission shaft 114 are respectively fixedly connected with a second driving bevel gear 115 and a spur gear 116. The second driving bevel gear 115 meshes with the first driving bevel gear 113. The upper surface of the ring 10 is fixedly connected with an internal gear ring 117, and the internal gear ring 117 meshes with the spur gear 116.

[0033] In specific implementation, since the driving motor 141 controls the rotation of the driving bevel gear 142 to drive the conical surface gear ring 143 to rotate, the rotation of the conical surface gear ring 143 can drive the driven bevel gear 112 on the right side of the first transmission shaft 111 to rotate. When the rotating driven bevel gear 112 rotates axially, it drives the first transmission shaft 111 and the first driving bevel gear 113 located on the left side of the first transmission shaft 111 to rotate axially synchronously. The rotating first driving bevel gear 113 then drives the second driving bevel gear 115 at the top of the second transmission shaft 114 to rotate. Further, the axial rotation of the second driving bevel gear 115 and the second transmission shaft 114 drives the spur gear 116 at the bottom of the second transmission shaft 114 to rotate axially. At the same time, since the spur gear 116 meshes with the internal gear ring 117 fixedly connected to the upper surface of the ring 10, the rotation of the spur gear 116 can drive the internal gear ring 117 and the ring 10 to rotate. The rotating ring 10 then drives the connecting shaft 12 and the connecting plate 13 at its bottom end to perform a circular motion, thereby realizing the control of the circular rotation of the sealing plate 16 and the oil filter box 17.

[0034] Further, sliders are fixedly connected to the top and bottom of the plurality of sealing plates 16. Annular sliding grooves 15 which are slidably matched with the sliders are formed on the inner surface of the water outlet tank 7. The plurality of sealing plates 16 are respectively slidably connected through the sliders and the annular sliding grooves 15.

[0035] In specific implementation, through the cooperation of the annular chute 15 and the slider, the sealing plate 16 can rotate circumferentially inside the water outlet tank 7. At the same time, by using the chute, the sealing plate 16 and the connecting shaft 12, the support for the ring 10 can be realized, thereby facilitating the hoisting of the oil filter box 17 at the bottom of the ring 10 and improving the installation stability of the ring 10.

[0036] Furthermore, two first mounting seats 118 are fixedly connected to the top of the treatment cylinder 1, and the first transmission shaft 111 is respectively rotationally connected to the two first mounting seats 118.

[0037] In specific implementation, bearings are respectively embedded in the two first mounting seats 118, and the inner rings of the bearings are fixedly connected to the radial surfaces of the first transmission shaft 111. Through the two first mounting seats 118 and the bearings, it is convenient to horizontally fixedly install the first transmission shaft 111 at the upper end of the treatment cylinder 1. At the same time, the two first mounting seats 118 can improve the stability of the first transmission shaft 111 and increase the transmission effect of the first transmission shaft 111.

[0038] Furthermore, two second mounting seats 119 are longitudinally fixedly connected to one side of the treatment cylinder 1, and the second transmission shaft 114 is respectively rotationally connected to the two second mounting seats 119.

[0039] In specific implementation, bearings are respectively embedded in the two second mounting seats 119, and the inner rings of the bearings are fixedly connected to the radial surfaces of the second transmission shaft 114. Through the two second mounting seats 119 and the bearings, it is convenient to longitudinally fixedly install the second transmission shaft 114 on the side of the treatment cylinder 1. At the same time, the two second mounting seats 119 can improve the stability of the second transmission shaft 114 and increase the transmission effect of the second transmission shaft 114.

[0040] Furthermore, a material guiding rod 82 for facilitating material discharge is fixedly connected inside the separation cylinder 8.

[0041] In specific implementation, the material guiding rod 82 is obliquely fixedly connected inside the separation cylinder 8, and at the same time, the lower surface of the material guiding rod 82 contacts the upper surface of the support plate 9. When the support plate 9 rotates, the arrangement of the material guiding rod 82 facilitates the movement of the waste to the center position of the support plate 9, which is convenient for discharging the waste remaining on the support plate 9.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that; they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
