Description

Technical Field

[0001] This invention relates to a mixer having a rotary stirring device in a fixed container, and more particularly to an intelligent sealed preparation tank for oilfield chemicals. Background Technology

[0002] With heads held high and heads bowed low, the oil pumps work tirelessly day and night, extracting crude oil from thousands of meters underground, continuously supplying the nation's industrial lifeblood. However, the produced fluid extracted by the pumps contains not only crude oil, but also a large amount of water, a small amount of natural gas, and a certain amount of formation sand, mud, and other sediments. Existing mature technologies can separate and collect the water and natural gas from the produced fluid, but during the collection and transportation of produced fluid from the oil field, the sediments mostly settle at the bottom of the large tanks, requiring regular cleaning.

[0003] Sediment removal typically involves incineration or washing, which are energy-intensive and costly. To address these issues, engineers have intensified their research on the reuse of produced fluid sediment resources, following the principle of "from the formation, back to the formation," and have made breakthroughs in areas such as crude oil recovery from produced fluid sediments, particle size reduction of produced fluid sediments, formation sand control, and borehole sealing.

[0004] Hydraulic transport is the most convenient method for transferring sediments, thus requiring the addition of chemical treatment agents to prepare an emulsion suspension. Existing preparation equipment cannot automatically adjust the stirring speed according to the mass of the mixture in the container. Too slow a stirring speed can cause solids in the suspension to settle, while too fast a stirring speed results in excessive energy consumption and waste, leading to poor performance.

[0005] For example, Chinese utility model patent application number 201821771788.6 discloses "an automatic pharmaceutical preparation device," which includes a feeding box with a lid movably connected to its top. A motor is installed on the outside of the feeding box, and the output end of the motor is connected to a rotating shaft. A guide plate penetrating the feeding box is connected to the outside of the rotating shaft, and a first support plate is provided on the outside of the feeding box. This technical solution adds a one-way duckbill assembly and a duckbill opening to prevent water vapor from rising and causing pharmaceutical condensation during periods when pharmaceutical preparation is stopped. By setting up a vibration motor, some pharmaceuticals adhering to the inner wall of the feeding box can be shaken off, reducing raw material waste. By setting up a motor, rotating shaft, and guide plate, the time it takes for the pharmaceuticals to fall into the mixing chamber can be controlled, achieving a better dissolution effect.

[0006] Chinese invention patent application No. 202110070061.5 discloses an "automatic quantitative drug preparation device," which includes a solid drug dissolver, a preparation tank, a metering pump, and a water pipe. The solid drug dissolver stores a saturated solution of dissolved solid drug. The solid drug dissolver is connected to the preparation tank via a preparation pipeline. The metering pump is installed on the preparation pipeline, and the water pipe is connected to the preparation tank. The water pipe is equipped with an electric valve and an electronic water meter. This technical solution, during drug preparation, determines the required ratio of saturated solid drug solution to tap water based on the desired drug concentration in the preparation tank. The metering pump pumps a predetermined amount of saturated solid drug solution from the solid drug dissolver into the preparation tank. Once a predetermined amount of tap water is added to the preparation tank, the electric valve controls the water supply to be cut off, achieving long-term automatic drug dosing.

[0007] Chinese invention patent application No. 201810060980.2 discloses a "multi-stage stirring device for water treatment agents", which includes a mixing tank and a treatment tank. The mixing tank has two inlets, namely a sewage inlet pipe and a agent inlet pipe. The treatment tank is arranged in sequence according to the flow direction of the sewage, including a premixing component, a stirring and pushing component, and a stirring component. The sewage and agent are first mixed in the mixing tank. Then, the mixture is mixed a second and third time in the treatment tank according to the flow direction of the sewage, so as to achieve a more complete reaction.

The above-disclosed technical documents do not provide any technical inspiration for the more technical features, technical problems to be solved, and beneficial effects of the present invention.

[0027] 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.

[0028] Example 1

[0029] like Figure 1 , Figure 2 As shown, an intelligent sealed preparation tank for oilfield chemicals includes a tank body 1 with a hollow tank cavity 11 and several stirring devices 2. It should be noted that the number of stirring devices 2 should be determined based on the volume of the tank cavity 11. Figure 1 Three sets of stirring devices are given in the paper.

[0030] See Figure 1 , Figure 2 A feed pipe 12 communicating with the tank cavity 11 is provided at the top of one end of the tank body 1, and a discharge port 13 communicating with the tank cavity 11 is provided at the end of the tank body 1 away from the feed pipe 12. Liquids containing sediments and chemical treatment agents can be fed into the tank cavity 11 through the feed pipe 12 and discharged through the discharge port 13 after preparation. For ease of maintenance, a manhole 14 communicating with the tank cavity 11 is provided at the top of the tank body 1, and a breather valve 15 communicating with the tank cavity 11 is provided at the top of the tank body 1 to maintain the pressure balance inside the tank cavity 11 and reduce the volatilization of substances.

[0031] like Figure 2 As shown, the stirring device 2 includes a servo motor 21, a stirring rod 22, and a stirring column 23. The servo motor 21 is mounted on the top outer side of the tank body 1, and its output shaft extends into the tank cavity 11. The stirring rod 22 is vertically rotatably supported inside the tank cavity 11. The fixed ends of the stirring column 23 are evenly distributed radially along the outer circumference of the stirring rod 22 and arranged in multiple layers along the axial direction of the stirring rod 22. The servo motor 21 drives the stirring rod 22 to rotate, thereby causing the stirring column 23 to stir the mixture inside the tank cavity 11.

[0032] The present invention also includes a speed regulating device 3, such as Figures 2-4As shown, the speed regulating device 3 includes a guide rod 31, a float 32, a support rod 33, a sliding rod 34, a sliding block 35, a sliding plate 36, a rheostat 37, and a controller 38. The guide rod 31 is vertically arranged inside the tank cavity 11 on one side of the stirring rod 22. The float 32 is fitted onto the guide rod 31 and slides vertically along the guide rod 31. The sliding rod 34 is vertically arranged on the top of the outer side of the tank body 1. The sliding block 35 slides along the sliding rod 34. One end of the support rod 33 is connected to the float 32, and the other end passes through the tank body 1 and is connected to the sliding block 35. The rheostat 37 is arranged parallel to the sliding rod 34. One end of the sliding plate 36 is fitted onto the sliding block 35, and the other end is pressed against the rheostat 37. The sliding plate 36 is electrically connected to the controller 38 via a first wire 391. The servo motor 21 is electrically connected to the rheostat 37 and the controller 38 via a second wire 392 and a third wire 393, respectively.

[0033] Under the action of buoyancy, the float 32 rises and falls with the liquid level of the mixture in the tank cavity 11, thereby driving the swivel plate 36 to move on the rheostat 37 via the support rod 33 and the sliding block 35. This changes the resistance value in the circuit connected to the controller 38 and the servo motor 21, thereby realizing the speed control of the servo motor 21 and achieving the purpose of energy saving and consumption reduction. Specifically, when the liquid level of the mixture in the tank cavity 11 is high, the resistance value of the rheostat 37 connected to the circuit is small, and the speed of the servo motor 21 is fast; conversely, when the liquid level of the mixture in the tank cavity 11 is low, the resistance value of the rheostat 37 connected to the circuit is large, and the speed of the servo motor 21 is slow.

[0034] The present invention also includes a linkage heat dissipation device 4, such as Figure 2 , Figure 3 and Figure 5 As shown, the linkage heat dissipation device 4 includes a cover 41, a linkage rod 42, a fan blade 43, and a linkage assembly 44. The cover 41 is located on the top of the outer side of the tank body 1, covering the servo motor 21, the rheostat 37, the sliding rod 34, and the sliding block 35. A heat dissipation window 45 is opened on the cover 41, and a heat dissipation filter 46 is provided on the heat dissipation window 45. The controller 38 is mounted on the top of the outer side of the cover 41. The linkage rod 42 is vertically rotatably positioned between the cover 41 and the tank body 1. A limiting sleeve 47 is rotatably fitted on the linkage rod 42. A shaft 48 is horizontally rotatably positioned between the limiting sleeve 47 and the cover 41. The fan blade 43 is coaxially mounted on the shaft 48. The linkage assembly 44 includes a first gear 441, a second gear 442, and a third gear 443 that mesh sequentially. The first gear 441 is coaxially mounted on the output shaft of the servo motor 21, the second gear 442 is coaxially mounted on the linkage rod 42, and the third gear 443 is coaxially mounted on the shaft 48.

[0035] The torque output by the servo motor 21 drives the shaft 48 to rotate via the first gear 441, the second gear 442, and the third gear 443. This, in turn, drives the fan blades 43 on the shaft 48 to rotate, which in turn blows the air around the servo motor 21 out of the housing 41 through the heat dissipation filter 46 on the heat dissipation window 45, thus extending the service life of the servo motor 21. Clearly, the rotation speed of the fan blades 43 varies with the rotation speed of the servo motor 21, ensuring that the speed is neither too slow, reducing heat dissipation efficiency, nor too high, consuming excessive energy, further enhancing the energy-saving and consumption-reducing effect of this invention.

[0036] To enhance airflow within the hood 41, such as Figure 5 As shown, the linkage heat dissipation device 4 of the present invention further includes a plunger air intake assembly 49, wherein the plunger air intake assembly 49 includes a cam 491, a pressing plate 492, a sleeve 493, a piston rod 494, and a piston head 495. The cam 491 is coaxially mounted on the linkage rod 42. The sleeve 493 is horizontally mounted on the outside of the housing 41. An air intake hole 411 communicating with the sleeve 493 is opened on the housing 41. A one-way air intake valve 496 is provided at the end of the sleeve 493 away from the housing 41. The piston head 495 is slidably mounted inside the sleeve 493. One end of the piston rod 494 is connected to the piston head 495, and the other end extends into the housing 41 and is connected to the pressing plate 492. A support spring 497 is provided between the pressing plate 492 and the housing 41. The pressing plate 492 is pressed against the contour of the cam 491.

[0037] The torque output by the servo motor 21 drives the linkage rod 42 to rotate via the first gear 441 and the second gear 442. This, in turn, drives the cam 491 on the linkage rod 42 to rotate. The cam 491 and the support spring 497 work together to act on the extrusion plate 492, causing the extrusion plate 492 to drive the piston rod 494 to push the piston head 495 to reciprocate within the sleeve 493, blowing air from outside the casing 41 toward the servo motor 21. Unlike natural static cooling, the airflow from the plunger air intake assembly 49 toward the servo motor 21 is fast, resulting in high heat dissipation efficiency.

[0038] Example 2

[0039] The difference from Embodiment 1 is that this embodiment also includes a crushing and filtering assembly 5, which includes a first crushing rod 51, a slider 52, a travel block 53, and an elastic filter screen 54, as shown below. Figure 6 , Figure 7As shown, a connecting groove 231 and a through groove 232 are axially formed on the free end of the stirring column 23. The slider 52 is slidably disposed within the groove 231, with one end connected to the stirring column 23 by a tension spring 55, and the other end connected to the fixed end of the stroke block 53. The stroke block 53 is a cone whose diameter gradually decreases from the fixed end to the free end. Its free end extends out of the stirring column 23 through the through groove 232. Several rod holes 233 are radially formed on the stirring column 23 corresponding to the through groove 232. One end of the first crushing rod 51 is pressed against the circumference of the stroke block 53 by a push plate 56, and the other end extends out of the stirring column 23 through the rod hole 233. A return spring 57 is fitted onto the first crushing rod 51 between the push plate 56 and the stirring column 23. Figure 2 , Figure 8 As shown, the elastic filter screen 54 is assembled in the tank cavity 11 on one side of the stirring rod 22 via the filter frame 58. The elastic filter screen 54 is provided with a first permanent magnet 59 at intervals, and the free end of the stroke block 53 is provided with a second permanent magnet 60.

[0040] When the stirring rod 22 rotates at a high speed, centrifugal force causes the slider 52 and the stroke block 53 to move away from the stirring rod 22 along the slide groove 231 against the tension spring 55. The stroke block 53 pushes the first crushing rod 51 to extend out of the rod hole 233, crushing large particles of sediment in the mixture in the tank cavity 11. The extension length of the first crushing rod 51 changes in real time with the rotation speed of the stirring rod 22 to maintain the stirring efficiency of the mixture in the tank cavity 11.

[0041] When the free end of the stirring column 23 periodically approaches and moves away from the elastic filter 54, the second permanent magnet 60 located at the end of the stroke block 53 generates a periodic attraction effect on the first permanent magnet 59. The first permanent magnet 59 drives the elastic filter 54 to vibrate at a certain frequency, which can shake off the deposits adhering to the elastic filter 54, avoid clogging of the elastic filter 54, and improve the throughput efficiency of the elastic filter 54.

[0042] Example 3

[0043] The difference from embodiments 1 and 2 is that, in this embodiment, the crushing and filtering assembly 5 further includes a second crushing rod 61, a connecting rod 62, and a guide plate 63, as shown below. Figure 6 , Figure 9 As shown, several guide grooves 234 are opened along the axial direction on the stirring column 23 corresponding to the chute 231. The fixed end of the connecting rod 62 is connected to the slider 52. The connecting end extends out of the stirring column 23 through the guide grooves 234. The guide plate 63 is fixed horizontally on the connecting end of the connecting rod 62. The second crushing rod 61 is arranged radially along the stirring column 23 on the side of the guide plate 63 away from the connecting rod 62. Baffles 64 are provided on the stirring columns 23 on both sides of the guide plate 63. The height of the baffles 64 gradually decreases from the side closer to the stirring rod 22 to the side away from the stirring rod 22.

[0044] When the stirring rod 22 rotates at a high speed, centrifugal force causes the slider 52 and the stroke block 53 to move away from the stirring rod 22 along the slide groove 231 against the tension spring 55. The end of the second crushing rod 61 extends out between the baffles 64. The extension length of the second crushing rod 61 changes in real time with the rotation speed of the stirring rod 22, which further improves the crushing efficiency of the sediment in the tank cavity 11 and accelerates the mixing of the chemical treatment agent and the sediment.

[0045] This invention uses a speed adjustment device 3 to control the speed of the servo motor 21, increasing its speed when the liquid level in the mixture inside the tank 11 is high and decreasing it when the liquid level is low, thus achieving energy saving and consumption reduction. A linked heat dissipation device 4 matches the heat dissipation rate according to the rotation speed of the servo motor 21, further enhancing the energy saving and consumption reduction effect. A plunger air intake assembly 49 blows air from outside the casing 41 towards the servo motor 21, resulting in fast airflow and high heat dissipation efficiency. A crushing and filtering assembly 5 not only crushes large particles of sediment in the mixture inside the tank 11, accelerating the mixing of the chemical treatment agent and sediment, but also causes the elastic filter screen 54 to vibrate at a certain frequency, shaking off sediment from the elastic filter screen 54 and improving its throughput.
