Description

Technical Field

[0001] This invention relates to the field of oil-water separation detection technology, specifically to a device for detecting oil-water separation in a magnetic reactor. Background Technology

[0002] Magnetic drive reactors, also known as magnetically stirred reactors, are reaction equipment widely used in many fields such as chemical, pharmaceutical, and food industries. They primarily utilize magnetic couplers to achieve contactless power transfer, thereby driving the stirrer to achieve material mixing and reaction. Detection of oil-water stratification in magnetic drive reactors is a crucial step in ensuring production quality and safe equipment operation.

[0003] Existing methods for detecting oil-water stratification in magnetic reactors mainly include direct observation, hydrometer detection, capacitive sensor detection, and ultrasonic detection. These methods are easily constrained by various external conditions. For example, direct observation requires a large observation window on the reactor body, making it unsuitable for high-temperature, high-pressure magnetic reactors. Methods using hydrometers or sensors require precision calibration, which can easily introduce measurement errors. Therefore, there is an urgent need for a detection device that can accurately reflect the oil-water stratification within the reactor. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The liquid structure above and below the liquid surface is sampled by the detection tube and sampling ball set on the detection frame. First, the sliding ball sleeve gradually slides down along the detection rod assembly. Due to the rotational engagement between the center of the mating disc and the sliding ball sleeve, the mating disc remains horizontal during the descent, allowing the detection tube and sampling ball to gradually insert into the liquid at an angle perpendicular to the water surface. When the sampling ball contacts the liquid surface, the liquid passes through the sampling port at the bottom of the sampling ball, pushes open the sealing plate and connecting membrane, and enters the sampling ball. As the sampling ball gradually inserts into the liquid, it samples the oil-water stratification structure in the liquid. Finally, the sampling detection tube is raised to the observation window of the detection port, and the specific situation of oil-water stratification on the liquid surface inside the vessel is determined by observation with the help of an observation camera or manual observation.

[0018] (2) To ensure the stability of the floating detection mechanism during the descent sampling process and the balance during the recovery and ascent process, the sliding ball sleeve is firstly designed to cooperate with the first protrusion and the second receiving groove. This ensures that the sliding ball sleeve will not rotate relative to the detection rod assembly during the lifting and lowering process. At the same time, an arc-shaped limiting groove is set on the outside of the sliding ball sleeve. The cooperating disc automatically adjusts to a horizontal balance state along with the sliding ball sleeve during the lifting and lowering process. Due to the effect of the arc-shaped limiting groove, the cooperating disc will not rotate relative to the sliding ball sleeve, thereby avoiding relative rotation of the detection frame and detection tube set on the edge of the cooperating disc. This further improves the sampling stability of the floating detection mechanism and avoids interference and damage to the oil-water stratification structure of the liquid surface, thus further ensuring the sampling stability of the oil-water stratification structure.

[0019] (3) The tilting control cable drives the deceleration rod to rotate around the vertical rod, causing the deceleration rod to tilt and reducing the downward speed of the floating detection mechanism along the deceleration rod. The control cable is then used to drive the floating detection mechanism back to the detection port, allowing observation of the sampling tube in the floating detection mechanism through the observation window, thus obtaining the specific situation of oil-water stratification in the vessel. To facilitate the tilting control cable driving the deceleration rod to tilt, opening slot 1 and opening slot 2 are respectively set on the sliding ball sleeve and the mating disc. When the vertical rod and the deceleration rod are in a straight line, the tilting control cable is stored in the receiving slot 1 of the vertical rod and the deceleration rod. When the tilting control cable is shortened, it gradually moves outward from the receiving slot 1 along opening slot 1 and opening slot 2, thereby driving the deceleration rod to tilt and controlling the floating detection mechanism to decelerate and fall along the deceleration rod, ensuring the accuracy of sampling the oil-water stratification structure of the liquid surface.

[0033] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 8 , Figure 9As shown, a device for detecting oil-water stratification in a magnetic reactor includes a reactor body 1. A detection port 10 is provided on the reactor body 1. A detection control mechanism 4 is sealed and installed on the detection port 10. The detection control mechanism 4 is connected to a detection rod assembly 2. A floating detection mechanism 3 is slidably installed on the detection rod assembly 2. The detection control mechanism 4 controls the floating detection mechanism 3 to move on the detection rod assembly 2 and reach the liquid surface inside the reactor body 1 to sample the oil-water stratification state below the liquid surface. The floating detection mechanism 3 includes a sliding ball sleeve 30 slidably mounted on the detection rod assembly 2. A mating disc 31 is rotatably mounted on the outer side of the sliding ball sleeve 30. A detection frame 33 is provided on the edge of the mating disc 31. A detection tube 34 is mounted on the detection frame 33. The upper end of the detection tube 34 is open. A sampling ball 35 is connected to the bottom of the detection tube 34. The sampling ball 35 and the detection tube 34 are connected. A sampling port 352 is provided at the bottom of the sampling ball 35. A sealing plate 350 is provided on the sampling port 352. A connecting film 351 is provided on the side of the sealing plate 350 that is in contact with the sampling port 352. The edge of the connecting film 351 is fixedly connected to the edge of the sampling port 352. An observation window 11 is provided on the detection port 10.

[0035] Specifically, as the floating detection mechanism 3 slides along the detection rod assembly 2 to the surface of the liquid inside the vessel 1, it samples the liquid surface and the liquid structure below the liquid surface through the detection tube 34 and sampling ball 35 set on the detection frame 33. First, the sliding ball sleeve 30 gradually slides down along the detection rod assembly 2. Due to the rotational engagement between the center of the mating disc 31 and the sliding ball sleeve 30, the mating disc 31 remains horizontal during the descent, allowing the detection tube 34 and sampling ball 35 to gradually insert into the liquid at an angle perpendicular to the water surface. When the sampling ball 35 contacts the liquid surface, the liquid passes through the sampling port 352 at the bottom of the sampling ball 35, pushes open the sealing plate 350 and the connecting membrane 351, and enters the sampling ball 35. As the sampling ball 35 gradually inserts into the liquid, it samples the oil-water stratification structure in the liquid. Finally, the sampling detection tube 34 is raised to the observation window 11 of the detection port 10, and the specific situation of oil-water stratification on the liquid surface inside the vessel 1 is determined by using a camera or manual observation.

[0036] It is important to note that the detection tube 34 is transparent. When the liquid sampling is completed and the detection tube 34 is raised, the internal liquid pressure causes the sealing plate 350 and the connecting membrane 351 to block the sampling port 352, preventing leakage of the sampled liquid. Simultaneously, the sliding ball sleeve 30 and the mating disc 31 have cavities that generate buoyancy when in contact with the liquid surface, thus preventing the floating detection mechanism 3 from being completely submerged in the liquid and affecting the sample sampling.

[0037] Furthermore, such as Figures 2-6 , Figure 10 As shown, the detection rod assembly 2 includes a vertical rod 20 and a deceleration rod 21. The vertical rod 20 and the deceleration rod 21 are hinged together. The edges of the vertical rod 20 and the deceleration rod 21 are provided with a second receiving groove 211. The inner side of the sliding ball sleeve 30 is provided with a first mating protrusion 301 corresponding to the second receiving groove 211. The sliding ball sleeve 30 slides up and down along the second receiving groove 211 through the first mating protrusion 301. The outer side of the sliding ball sleeve 30 is provided with an arc-shaped limiting groove 302. The mating disc 31 is provided with a second mating protrusion 311 corresponding to the arc-shaped limiting groove 302. The mating disc 31 is slidably installed along the arc-shaped limiting groove 302 through the second mating protrusion 311.

[0038] Specifically, the detection rod assembly 2 includes a vertical rod 20 and a deceleration rod 21, and the vertical rod 20 and the deceleration rod 21 are hinged together. When the floating detection mechanism 3 moves from the vertical rod 20 to the deceleration rod 21, the deceleration rod 21 can be tilted by the detection control mechanism 4, thereby reducing the speed at which the floating detection mechanism 3 falls along the deceleration rod 21, and thus reducing the speed at which the detection tube 34 and the sampling ball 35 reach the liquid surface and the sampling speed during the sampling process, avoiding liquid surface oscillation during the sampling process and ensuring sampling accuracy.

[0039] More specifically, to ensure the stability of the floating detection mechanism 3 during the descent sampling process and the balance during the recovery and ascent process, the sliding ball sleeve 30 firstly cooperates with the first protrusion 301 and the second receiving groove 211. This prevents the sliding ball sleeve 30 from rotating relative to the detection rod assembly 2 during the lifting and lowering process. Simultaneously, an arc-shaped limiting groove 302 is provided on the outer side of the sliding ball sleeve 30. The cooperating disc 31 automatically adjusts to a horizontal equilibrium state along with the sliding ball sleeve 30 during the lifting and lowering process. Due to the effect of the arc-shaped limiting groove 302, the cooperating disc 31 will not rotate relative to the sliding ball sleeve 30, thereby preventing relative rotation of the detection frame 33 and detection tube 34 set at the edge of the cooperating disc 31. This further improves the sampling stability of the floating detection mechanism 3, avoids interference with or damage to the oil-water stratification structure of the liquid surface, and thus further ensures the sampling stability of the oil-water stratification structure.

[0040] Furthermore, such as Figures 2-7As shown, the detection control mechanism 4 includes a tilt control cable 40 and a retraction control cable 41. The vertical rod 20 and the deceleration rod 21 are provided with a receiving groove 1 210 and a receiving groove 211. The tilt control cable 40 and the receiving groove 1 210 cooperate with each other. The end of the tilt control cable 40 is fixedly connected to the end of the deceleration rod 21. The sliding ball sleeve 30 is provided with an opening groove 1 300 corresponding to the receiving groove 1 210. The mating disc 31 is provided with an opening groove 2 310 corresponding to the opening groove 1 300. The end of the retraction control cable 41 is fixedly connected to the mating protrusion 1 301.

[0041] Specifically, the tilting control cable 40 drives the deceleration rod 21 to rotate around the vertical rod 20, causing the deceleration rod 21 to tilt and reduce the downward speed of the floating detection mechanism 3 along the deceleration rod 21; the retraction control cable 41 drives the floating detection mechanism 3 back to the detection port 10, thereby allowing the observation window 11 to observe the sampling detection tube 34 in the floating detection mechanism 3 and obtain the specific situation of oil-water stratification in the vessel body 1. To facilitate the tilting of the deceleration rod 21 by the tilting control cable 40, an opening groove 300 and an opening groove 310 are respectively provided on the sliding ball sleeve 30 and the mating disc 31. When the vertical rod 20 and the deceleration rod 21 are in a straight line, the tilting control cable 40 is stored in the receiving groove 210 of the vertical rod 20 and the deceleration rod 21. When the tilting control cable 40 is shortened, it moves outward from the receiving groove 210 along the opening groove 300 and the opening groove 310, thereby tilting the deceleration rod 21 and controlling the floating detection mechanism 3 to decelerate and fall along the deceleration rod 21, ensuring the accuracy of sampling the oil-water stratification structure of the liquid surface.

[0042] In particular, due to the setting of the second opening slot 310, a counterweight needs to be set at the bottom of the mating disc 31 to ensure that the mating disc 31 automatically adjusts to a horizontal balance state when it rises and falls with the sliding ball sleeve 30.

[0043] Furthermore, such as Figure 11 , Figure 12 As shown, a cover 401 is provided on the detection port 10, and a plug-in cylinder 400 is fixedly installed on the cover 401. A control frame 45 is provided at the end of the plug-in cylinder 400, and a mounting plate 46 is placed on the control frame 45. The vertical rod 20 is fixedly connected to the bottom of the mounting plate 46, and the mounting plate 46 is plugged into the top of the control frame 45 through the vertical rod 20. A winding drum 48 is rotatably installed on the mounting plate 46, and the tilting control cable 40 and the winding drum 48 are wound around each other. A motor frame 470 is provided on the mounting plate 46, and a motor 47 is provided on the motor frame 470. The motor 47 is connected to the winding drum 48.

[0044] Specifically, when the tilt control cable 40 needs to be tilted by winding the drum 48, the tilt control cable 40 is wound up by the motor 47, which shortens the tilt control cable 40 and pulls the end of the deceleration rod 21 to deflect relative to the vertical rod 20. After completing the liquid oil-water stratification sampling, the tilt control cable 40 is released again so that the deceleration rod 21 returns to the vertical position with the vertical rod 20, which facilitates the recovery of the control cable 41 to drive the floating detection mechanism 3 back to the detection port 10, and the liquid oil-water stratification is observed in conjunction with the observation window 11.

[0045] Furthermore, such as Figure 4 , Figure 6 As shown, the first receiving groove 210 and the second receiving groove 211 are symmetrically arranged on both sides of the vertical rod 20 and the deceleration rod 21. The axis of the detection frame 33 is perpendicular to the plane between the first receiving groove 210 and the second receiving groove 211.

[0046] Specifically, the first receiving groove 210 and the second receiving groove 211 are symmetrically arranged on both sides of the vertical rod 20 and the deceleration rod 21, thereby separating the tilt control cable 40 and the recovery control cable 41, avoiding interference between the two, and ensuring that the tilt control of the deceleration rod 21 and the recovery control of the floating detection mechanism 3 do not interfere with each other.

[0047] Furthermore, such as Figure 12 As shown, a second winding drum 490 is rotatably mounted on the mounting plate 46. A second motor 49 is connected to the end of the second winding drum 490. The end of the recovery control cable 41 is wound around the second winding drum 490.

[0048] Furthermore, such as Figure 12 As shown, a guide cylinder 480 is provided at the connection between the tilt control cable 40 and the mounting plate 46, a guide cylinder 491 is provided at the connection between the retrieval control cable 41 and the mounting plate 46, a positioning frame 450 is provided on the control frame 45, and the edge of the mounting plate 46 and the positioning frame 450 cooperate with each other.

[0049] Specifically, guide cylinder 1 480 and guide cylinder 2 491 are respectively installed on the mounting plate 46 to ensure the smooth release and retraction control of the tilt control cable 40 and the retrieval control cable 41, and to avoid excessive wear or knots during the release and retraction of the tilt control cable 40 and the retrieval control cable 41.

[0050] Furthermore, such as Figure 7 , Figure 11As shown, the mating disc 31 has multiple mating posts 32 on its upper side, and each mating post 32 has a snap-fit ​​groove 320. The insertion tube 400 has a mating flange 43 at one end located inside the detection port 10. The mating flange 43 has a mating hole 44 corresponding to the mating post 32. A snap-fit ​​ring 42 is fixedly installed on the outer wall of the insertion tube 400. After the mating post 32 passes through the mating hole 44, the snap-fit ​​groove 320 and the snap-fit ​​ring 42 cooperate with each other. A rubber ring is provided on the outer side of the snap-fit ​​ring 42. A push ring 200 is provided on the vertical rod 20.

[0051] Specifically, after the floating detection mechanism 3 is retracted to the detection port 10, it connects with the mating post 32 on the mating disc 31 and the mating hole 44 of the mating flange 43. When the snap-fit ​​groove 320 on the mating post 32 engages with the outer ring of the snap-fit ​​ring 42, it forms a snap-fit ​​limit on the mating disc 31, preventing the floating detection mechanism 3 from sliding down the detection rod assembly 2. At the same time, a push ring 200 is set on the vertical rod 20. When the cover 401 is inserted into the insertion tube 400 along with the detection rod assembly 2, the push ring 200 on the vertical rod 20 contacts the upper end of the sliding ball sleeve 30. Pressing the sliding ball sleeve 30 will cause the floating detection mechanism 3 to fall down along the detection rod assembly 2 for sampling and detection.

[0052] Furthermore, such as Figure 5 As shown, an opening frame 212 is symmetrically and rotatably mounted on the end of the deceleration rod 21, and a hidden groove for accommodating the opening frame 212 is provided inside the deceleration rod 21.

[0053] Specifically, the recovery control cable 41 also has a function of adjusting its length according to the change in the liquid level in the vessel 1, thereby adjusting the falling height of the floating detection mechanism 3. In order to prevent the floating detection mechanism 3 from detaching from the end of the deceleration rod 21 due to excessive release of the recovery control cable 41, an opening frame 212 is set at the end of the deceleration rod 21. When the floating detection mechanism 3 is installed, the opening frame 212 is retracted into the hidden groove, and then the opening frame 212 opens outward to prevent the floating detection mechanism 3 from detaching from the deceleration rod 21.

[0054] Furthermore, such as Figure 11 As shown, a positioning post 410 is provided at the bottom edge of the plug-in tube 400, and an installation hole is provided on the cover 401 that mates with the positioning post 410. The plug-in tube 400 is positioned and installed between the positioning post 410 and the cover 401.

[0055] The working principle of this invention embodiment is as follows:

[0056] like Figures 1-12As shown, during the process of the floating detection mechanism 3 sliding along the detection rod assembly 2 to the surface of the liquid inside the vessel 1, the detection tube 34 and sampling ball 35 set on the detection frame 33 are used to sample the liquid structure on and below the liquid surface. First, the sliding ball sleeve 30 gradually slides down along the detection rod assembly 2. Due to the rotational engagement between the center of the mating disc 31 and the sliding ball sleeve 30, the mating disc 31 remains horizontal during the descent, allowing the detection tube 34 and sampling ball 35 to gradually insert into the liquid at an angle perpendicular to the water surface. When the sampling ball 35 contacts the liquid surface, the liquid passes through the sampling port 352 at the bottom of the sampling ball 35, pushes open the sealing plate 350 and the connecting membrane 351 and enters the sampling ball 35. During the process of gradually inserting into the liquid, the sampling ball 35 samples the oil-water stratification structure in the liquid. Finally, the sampling detection tube 34 is raised to the observation window 11 of the detection port 10. With the help of an observation camera or manual observation, the specific situation of oil-water stratification on the liquid surface inside the vessel 1 is determined. The detection rod assembly 2 includes a vertical rod 20 and a deceleration rod 21, with the vertical rod 20 and the deceleration rod 21 hinged together. During the transfer of the floating detection mechanism 3 from the vertical rod 20 to the deceleration rod 21, the deceleration rod 21 can be tilted by the detection control mechanism 4, thereby reducing the speed at which the floating detection mechanism 3 falls along the deceleration rod 21. This, in turn, reduces the speed at which the detection tube 34 and the sampling ball 35 reach the liquid surface, as well as the sampling speed during the sampling process, preventing liquid surface oscillation and ensuring sampling accuracy. To ensure the stability of the floating detection mechanism 3 during the descent sampling process and the balance during the recovery and ascent process, the sliding ball sleeve 30, in conjunction with the first protrusion 301 and the second receiving groove 211, cooperates with each other. This ensures that the sliding ball sleeve 30 does not rotate relative to the detection rod assembly 2 during the lifting and lowering process. Meanwhile, an arc-shaped limiting groove 302 is provided on the outer side of the sliding ball sleeve 30. The cooperating disc 31 automatically adjusts to a horizontal equilibrium state during the lifting and lowering process of the sliding ball sleeve 30. Due to the arc-shaped limiting groove 302, the cooperating disc 31 will not rotate relative to the sliding ball sleeve 30, thus preventing relative rotation of the detection frame 33 and detection tube 34 set at the edge of the cooperating disc 31. This further improves the sampling stability of the floating detection mechanism 3 and avoids interference with the oil-water stratification structure of the liquid surface, thereby further ensuring the sampling stability of the oil-water stratification structure. The tilting control cable 40 drives the deceleration rod 21 to rotate around the vertical rod 20, causing the deceleration rod 21 to tilt and reduce the downward speed of the floating detection mechanism 3 along the deceleration rod 21. The retraction control cable 41 drives the floating detection mechanism 3 back to the detection port 10, allowing observation of the sampling detection tube 34 in the floating detection mechanism 3 through the observation window 11, thus obtaining the specific situation of oil-water stratification within the vessel body 1.To facilitate the tilting of the deceleration rod 21 by the tilting control cable 40, an opening groove 300 and an opening groove 310 are respectively provided on the sliding ball sleeve 30 and the mating disc 31. When the vertical rod 20 and the deceleration rod 21 are in a straight line, the tilting control cable 40 is stored in the receiving groove 210 of the vertical rod 20 and the deceleration rod 21. When the tilting control cable 40 is shortened, it moves outward from the receiving groove 210 along the opening groove 300 and the opening groove 310, thereby tilting the deceleration rod 21 and controlling the floating detection mechanism 3 to decelerate and fall along the deceleration rod 21, ensuring the accuracy of sampling the oil-water stratification structure of the liquid surface. When the tilt control cable 40 is wound around the drum 48, and the deceleration lever 21 needs to be tilted, the tilt control cable 40 is wound up by the motor 47, which shortens the tilt control cable 40 and pulls the end of the deceleration lever 21 to deflect relative to the vertical rod 20. After the liquid oil-water stratification sampling is completed, the tilt control cable 40 is released again so that the deceleration lever 21 returns to the vertical position with the vertical rod 20, which facilitates the recovery of the control cable 41 to drive the floating detection mechanism 3 back to the detection port 10, and the liquid oil-water stratification is observed in conjunction with the observation window 11. After the floating detection mechanism 3 is retracted to the detection port 10, it connects with the mating post 32 on the mating disc 31 and the mating hole 44 of the mating flange 43. When the snap-fit ​​groove 320 on the mating post 32 engages with the outer ring of the snap-fit ​​ring 42, it forms a snap-fit ​​limit on the mating disc 31, preventing the floating detection mechanism 3 from sliding down the detection rod assembly 2. At the same time, a push ring 200 is set on the vertical rod 20. When the cover 401 is inserted into the insertion tube 400 along with the detection rod assembly 2, the push ring 200 on the vertical rod 20 contacts the upper end of the sliding ball sleeve 30. Pressing the sliding ball sleeve 30 will cause the floating detection mechanism 3 to fall down along the detection rod assembly 2 for sampling and detection.
