Description

Technical Field

[0001] This utility model relates to the field of oil drilling technology, and in particular to an integrated drilling fluid circulation, purification and separation machine. Background Technology

[0002] An integrated drilling fluid circulation, purification, and separation machine is an integrated solids control equipment designed for the needs of oil drilling operations. It integrates drilling fluid circulation, purification, and solid-liquid separation functions into a single system platform.

[0003] Currently, when sieving particles in drilling fluid, the screens are usually static, causing particles to accumulate during the sieving process and making it difficult to sieve them quickly. At the same time, when drilling fluid is used for gas-liquid separation at high temperatures, the gas cannot be agitated and purified multiple times, resulting in incomplete gas purification and environmental pollution.

[0004] Therefore, a new type of integrated drilling fluid circulation, purification, and separation machine is needed. Utility Model Content

[0005] The purpose of this invention is to solve the problems of low particle filtration efficiency and incomplete gas purification in drilling fluid, and to propose an integrated drilling fluid circulation purification and separation machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a drilling fluid circulation purification and separation integrated machine, including a support, a spring mechanism and a stirring mechanism, wherein the spring mechanism includes a contact block and a moving plate, the upper surface of the moving plate is fixedly connected to the lower surface of the contact block, and the moving plate and the contact block are used to provide spring force so as to increase the drilling fluid filtration efficiency;

[0007] The agitation mechanism includes an activated carbon plate and cotton strips. The side surface of the cotton strips is connected to the side surface of the activated carbon plate. The activated carbon plate and cotton strips are used to agitate and beat the gas in the drilling fluid, thereby improving the gas purification quality of the drilling fluid. By utilizing the contact block's contact with the second sieve plate, the contact block can be moved by the impact, and the contact block can bounce back according to the movement of the first and second sieve plates, increasing the bounce frequency of the first and second sieve plates. At the same time, the activated carbon plate and cotton strips can simultaneously adsorb, filter, and beat the high-temperature heated drilling fluid, allowing for multiple purifications of the heated drilling fluid, thereby improving the gas purification effect in the drilling fluid.

[0008] Preferably, the spring mechanism further includes a support column, the outer surface of which is slidably connected to the side surface of the moving plate, and a first spring is fixedly connected to the lower surface of the moving plate, with the bottom end of the first spring fixedly connected to the support column. When the moving plate rapidly squeezes the first spring, the first spring is affected by the compression and can push the moving plate upward, thereby increasing the sliding range between the first sieve plate and the second sieve plate and improving the sieving efficiency of the drilling fluid.

[0009] Preferably, the stirring mechanism further includes a movable rod, both sides of which are fixedly connected to the side surface of the activated carbon plate. By rotating the movable rod, the activated carbon plate can be driven to rotate. During the rotation, the cotton strip can beat the gas, and together with the activated carbon plate, the gas can be stirred, allowing the gas to be purified multiple times, thereby improving the gas purification effect.

[0010] Preferably, a filter box is fixedly connected to the inner wall of the support, and the inner bottom wall of the filter box is fixedly connected to the bottom end of the support column. A water inlet pipe is fixedly connected to the side surface of the filter box, and a first connecting pipe is fixedly connected to the side surface of the filter box. A box cover is bolted to the upper surface of the filter box. A first sieve plate is slidably connected inside the filter box. A connecting plate is fixedly connected to the lower surface of the first sieve plate. A second sieve plate is fixedly connected to the lower surface of the connecting plate, and the second sieve plate is located above the support column. A tensioning mechanism is provided on the upper surface of the first sieve plate. The tensioning mechanism includes a tension plate, the lower surface of which is fixedly connected to the upper surface of the first sieve plate, and the upper surface of the tension plate extends out of the inner surface of the box cover. The first and second sieve plates are fixedly connected to a horizontal plate on their side surface. A second spring is fixedly connected to the lower surface of the horizontal plate, and the bottom end of the second spring is fixedly connected to the upper surface of the cover. Because the mesh diameters of the first and second sieve plates are different, they can sieve particles of different diameters in the drilling fluid. The lower part of the second sieve plate can fit against the contact block to compress the first spring, so that the stretching plate and the contact block can increase the elastic force of the first and second sieve plates to move up and down. The first and second sieve plates can slide up and down inside the box. By utilizing the elasticity of the first and second springs, the sliding height of the first and second sieve plates can be increased, thereby sieving particles in the drilling fluid.

[0011] Preferably, a sedimentation tank is fixedly connected to the inner wall of the support, and the sedimentation tank is located to the right of the filter box. The interior of the sedimentation tank is connected to the first connecting pipe. A drain pipe is fixedly connected to the front surface of the sedimentation tank. A separation mechanism is provided inside the sedimentation tank. The separation mechanism includes a first perforated plate, which is slidably connected to the interior of the sedimentation tank. A rotating rod is movably connected to the upper surface of the first perforated plate via a bearing. A second perforated plate is fixedly connected to the upper surface of the rotating rod. A fixed rod is fixedly connected to the upper surface of the second perforated plate, and the top end of the fixed rod extends out of the interior of the sedimentation tank. A threaded plate is fixedly connected to the top end of the fixed rod. A threaded rod is threadedly connected to the interior of the threaded plate, and the bottom end of the threaded rod is threadedly connected to the interior of the sedimentation tank. Rotating the fixed rod allows the second perforated plate to rotate on the surface of the first perforated plate, so that the mesh holes inside the first and second perforated plates are staggered, separating the sediment of the drilling fluid from the separated drilling fluid, thereby improving the sedimentation and separation effect of the drilling fluid.

[0012] Preferably, a gas purification box is fixedly connected to the side surface of the bracket, and the interior of the gas purification box is movably connected to the bottom end of the rotating rod via a bearing. A second connecting pipe is fixedly connected to the side surface of the gas purification box, and the left end of the second connecting pipe communicates with the sedimentation tank. A water outlet pipe is fixedly connected to the front surface of the gas purification box. A motor is installed on the upper surface of the gas purification box, and the output end of the motor is fixedly connected to the top end of the rotating rod. A purification mechanism is installed on the upper surface of the gas purification box, and the purification mechanism includes a purification pipe located behind the motor. The purification pipe contains absorbent cotton. A heating box is fixedly connected to the side surface of the gas purification box, and an electric heating tube is installed on the side surface of the heating box. After the gas is purified, it can be discharged through the purification pipe. Because the purification pipe contains absorbent cotton, it can absorb and discharge the gas that is about to be discharged again. The water outlet pipe can discharge the drilling fluid remaining in the gas purification box.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first and second sieve plates can slide inside the filter box and come into contact with the surface of the contact block due to the impact of the drilling fluid entering and being discharged. The contact block can drive the moving plate to slide inside the support column and squeeze the first spring due to the downward impact of the second sieve plate. Utilizing the elasticity of the first spring, when the moving plate squeezes the first spring quickly, the first spring can be pushed upward by the squeeze. Combined with the movement of the tension plate and the compression of the second spring by the horizontal plate, the sliding range of the first and second sieve plates can be increased, thereby improving the sieving efficiency of the drilling fluid.

[0015] 2. In this utility model, the rotation of the movable rod drives the activated carbon plate to rotate. Since the cotton strip is a textile material, when the activated carbon plate rotates, the cotton strip, due to inertia, can form tension and rotate parallel to the activated carbon plate. The activated carbon plate can adsorb and filter the high-temperature heated drilling fluid, allowing it to adsorb and remove harmful substances and odors from the drilling fluid gas. The cotton strip allows the gas to be adsorbed into its interior, and during the rotation of the cotton strip, it can beat the gas, which, together with the activated carbon plate, can agitate the gas, allowing the gas to be purified multiple times, thereby improving the gas purification effect.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Please see Figure 1-3 The present invention provides a technical solution including a support 1, a spring mechanism 20 and a stirring mechanism 13. The spring mechanism 20 includes a contact block 203 and a moving plate 204. The upper surface of the moving plate 204 is fixedly connected to the lower surface of the contact block 203. The moving plate 204 and the contact block 203 are used to provide spring force, so that it can increase the drilling fluid filtration efficiency.

[0024] The stirring mechanism 13 includes an activated carbon plate 132 and a cotton strip 133. The side surface of the cotton strip 133 is connected to the side surface of the activated carbon plate 132. The activated carbon plate 132 and the cotton strip 133 are used to beat and stir the gas in the drilling fluid, so as to improve the gas purification quality of the drilling fluid.

[0025] By utilizing the contact block 203's contact with the second sieve plate 19, the moving plate 204 can be moved by the impact. It can bounce back according to the movement of the first sieve plate 18 and the second sieve plate 19, increasing the bounce frequency of the first sieve plate 18 and the second sieve plate 19. At the same time, the activated carbon plate 132 and cotton strips 133 can simultaneously adsorb, filter, and beat the high-temperature heated drilling fluid, allowing for multiple purifications of the high-temperature heated drilling fluid, thereby improving the purification effect of the drilling fluid gas.

[0026] like Figure 1 and Figure 3 As shown, the spring mechanism 20 also includes a support column 202. The outer surface of the support column 202 is slidably connected to the side surface of the movable plate 204. A first spring 201 is fixedly connected to the lower surface of the movable plate 204, and the bottom end of the first spring 201 is fixedly connected to the support column 202.

[0027] When drilling fluid enters the filter box 2, the first screen plate 18 and the second screen plate 19 can slide inside the filter box 2 and come into contact with the surface of the contact block 203 due to the impact of the drilling fluid entering and discharging. The contact block 203 can drive the moving plate 204 to slide inside the support column 202 and squeeze the first spring 201 due to the downward impact of the second screen plate. Utilizing the elasticity of the first spring 201, when the moving plate 204 squeezes the first spring 201 quickly, the first spring 201 can push the moving plate 204 upward due to the squeezing effect, which can increase the sliding range of the first screen plate 18 and the second screen plate 19 and improve the sieving efficiency of the drilling fluid.

[0028] like Figure 2As shown, the stirring mechanism 13 also includes a movable rod 131, both sides of which are fixedly connected to the side surface of the activated carbon plate 132.

[0029] When drilling fluid enters the gas purification box 8, the rotation of the movable rod 131 causes the activated carbon plate 132 to rotate. Since the cotton strip 133 is made of textile material, when the activated carbon plate 132 rotates, the cotton strip 133, due to inertia, can form tension and rotate parallel to the activated carbon plate 132. The activated carbon plate 132 can adsorb and filter the high-temperature heated drilling fluid, allowing it to adsorb and remove harmful substances and odors in the drilling fluid gas. The cotton strip 133 allows the gas to be adsorbed into its interior, and during the rotation of the cotton strip 133, it can beat the gas, which, together with the activated carbon plate 132, can agitate the gas, allowing the gas to be purified multiple times, thereby improving the gas purification effect.

[0030] like Figure 1 and Figure 3 As shown, a filter box 2 is fixedly connected to the inner wall of the support 1, and the inner bottom wall of the filter box 2 is fixedly connected to the bottom end of the support column 202. A water inlet pipe 17 is fixedly connected to the side surface of the filter box 2, and a first connecting pipe 10 is fixedly connected to the side surface of the filter box 2. A box cover 3 is bolted to the upper surface of the filter box 2. A first sieve plate 18 is slidably connected inside the filter box 2. A connecting plate 21 is fixedly connected to the lower surface of the first sieve plate 18, and a second sieve plate 19 is fixedly connected to the lower surface of the connecting plate 21. The second sieve plate 19 is located above the support column 202. The upper surface of the first sieve plate 18 is provided with a tensioning mechanism 4. The tensioning mechanism 4 includes a tensioning plate 401. The lower surface of the tensioning plate 401 is fixedly connected to the upper surface of the first sieve plate 18. The upper surface of the tensioning plate 401 extends out of the interior of the box cover 3. A horizontal plate 402 is fixedly connected to the side surface of the tensioning plate 401. A second spring 403 is fixedly connected to the lower surface of the horizontal plate 402. The bottom end of the second spring 403 is fixedly connected to the upper surface of the box cover 3.

[0031] Drilling fluid can be discharged into the interior of the first sieve plate 18 and the second sieve plate 19 through the inlet pipe 17. Because the mesh diameters of the first sieve plate 18 and the second sieve plate 19 are different, they can screen particles of different diameters in the drilling fluid. After the drilling fluid enters the interior of the first sieve plate 18 and the second sieve plate 19, the sliding connection between the first sieve plate 18, the second sieve plate 19, and the filter box 2 allows the first sieve plate 18 and the second sieve plate 19 to be driven by the force of the drilling fluid discharge, causing the tension plate 401 to slide inside the box cover 3. According to the tension plate... The sliding of 401 allows the horizontal plate 402 to compress the second spring 403, while the lower part of the second screening plate 19 can fit against the contact block 203 to compress the first spring 201. This allows the tension plate 401 and the contact block 203 to increase the elasticity of the first screening plate 18 and the second screening plate 19 as they move up and down. The first screening plate 18 and the second screening plate 19 can slide up and down inside the housing. By utilizing the elasticity of the first spring 201 and the second spring 403, the sliding height of the first screening plate 18 and the second screening plate 19 can be increased, thereby enabling the screening of particles in the drilling fluid.

[0032] like Figure 1 and Figure 4 As shown, a sedimentation tank 5 is fixedly connected to the inner wall of the support 1, and the sedimentation tank 5 is located on the right side of the filter box 2. The interior of the sedimentation tank 5 is connected to the first connecting pipe 10. A drain pipe 12 is fixedly connected to the front surface of the sedimentation tank 5. A separation mechanism 16 is provided inside the sedimentation tank 5. The separation mechanism 16 includes a first hollow plate 163. The first hollow plate 163 is slidably connected to the interior of the sedimentation tank 5. A rotating rod 164 is movably connected to the upper surface of the first hollow plate 163 through a bearing. A second hollow plate 165 is fixedly connected to the upper surface of the rotating rod 164. A fixing rod 166 is fixedly connected to the upper surface of the second hollow plate 165. The top end of the fixing rod 166 extends out of the interior of the sedimentation tank 5. A threaded plate 161 is fixedly connected to the top end of the fixing rod 166. A threaded rod 162 is threadedly connected to the interior of the threaded plate 161. The bottom end of the threaded rod 162 is threadedly connected to the interior of the sedimentation tank 5.

[0033] After the drilling fluid is sieved, it can be discharged into the sedimentation tank 5 through the first connecting pipe 10 for sedimentation. After the drilling fluid has settled, the first perforated plate 163 and the second perforated plate 165 can be pushed downward together by the sliding of the fixed rod 166 and the sedimentation tank 5, depending on the sedimentation of the drilling fluid. The rotating rod 164 can make the first perforated plate 163 and the second perforated plate 165 rotate. The fixed rod 166 can be rotated on the surface of the first perforated plate 163, so that the mesh inside the first perforated plate 163 and the second perforated plate 165 are staggered, so that the sediment of the drilling fluid is separated from the separated drilling fluid. The threaded rod 162 can be twisted to extend into the sedimentation tank 5 to fix the fixed rod 166. The sediment can be discharged through the drain pipe 12, and the separated drilling fluid can be discharged into the gas purification tank 8 through the second connecting pipe 14 for high-temperature adsorption purification.

[0034] like Figure 1-2 As shown, a gas purification box 8 is fixedly connected to the side surface of the bracket 1, and the interior of the gas purification box 8 is movably connected to the bottom end of the movable rod 131 through a bearing. A second connecting pipe 14 is fixedly connected to the side surface of the gas purification box 8, and the left end of the second connecting pipe 14 is connected to the sedimentation box 5. A water outlet pipe 11 is fixedly connected to the front surface of the gas purification box 8. A motor 7 is provided on the upper surface of the gas purification box 8, and the output end of the motor 7 is fixedly connected to the top end of the movable rod 131. A purification mechanism 6 is provided on the upper surface of the gas purification box 8. The purification mechanism 6 includes a purification pipe 601, which is located behind the motor 7. An adsorption cotton 602 is provided inside the purification pipe 601. A heating box 15 is fixedly connected to the side surface of the gas purification box 8, and an electric heating tube 9 is provided on the side surface of the heating box 15.

[0035] After the drilling fluid has settled, it can be discharged into the gas purification box 8 through the second connecting pipe 14. The electric heating tube 9 is connected to an external power source to heat the drilling fluid in the gas purification box 8 at a high temperature. The motor 7 is connected to an external power source, and starting the motor 7 will drive the movable rod 131 to rotate. When the movable rod 131 rotates, it will drive the activated carbon plate 132 to rotate. The rotation of the activated carbon plate 132 and the cotton strip 133 will adsorb and beat the heated drilling fluid. The gas can be purified multiple times through the activated carbon plate 132 and the cotton strip 133, thereby improving the gas purification effect. After the gas is purified, it can be discharged through the purification pipe 601. Since the purification pipe 601 is equipped with adsorption cotton 602, it can adsorb and discharge the gas to be discharged again. The water outlet pipe 11 can discharge the drilling fluid remaining in the gas purification box 8.

[0036] The method of use and working principle of this device: Drilling fluid can be discharged into the interior of the first sieve plate 18 and the second sieve plate 19 through the water inlet pipe 17. Since the mesh diameters of the first sieve plate 18 and the second sieve plate 19 are different, the first sieve plate 18 and the second sieve plate 19 can screen particles of different diameters in the drilling fluid. The drilling fluid is discharged into the interior of the sedimentation tank 5 through the first connecting pipe 10 for sedimentation. The first hollow plate 163 and the second hollow plate 165 can be rotated by the rotating rod 164. The rotating fixed rod 166 can make the second hollow plate 165 rotate on the surface of the first hollow plate 163, so that the meshes inside the first hollow plate 163 and the second hollow plate 165 are staggered, so that the sediment of the drilling fluid is separated from the separated drilling fluid. The sediment can be discharged through the drain pipe 12, and the separated drilling fluid can be discharged into the interior of the gas purification tank 8 through the second connecting pipe 14 for high-temperature adsorption purification.

[0037] The drilling fluid in the gas purification box 8 can be heated to a high temperature using the electric heating tube 9. Starting the motor 7 can drive the movable rod 131 to rotate. When the movable rod 131 rotates, it can drive the activated carbon plate 132 to rotate. The rotation of the activated carbon plate 132 and the cotton strip 133 can adsorb and beat the heated drilling fluid. The gas can be purified multiple times through the activated carbon plate 132 and the cotton strip 133, thereby improving the gas purification effect. After the gas is purified, it can be discharged through the purification pipe 601. Since the purification pipe 601 is equipped with adsorption cotton 602, it can adsorb and discharge the gas that is about to be discharged again. The water outlet pipe 11 can discharge the drilling fluid remaining in the gas purification box 8.
