Description

Technical Field

[0001] This invention relates to the field of impurity separation in lubricating oil, specifically to an impurity filtration and separation device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering.

[0003] In the lubricating oil production process, the oil undergoes a series of steps: acid-base neutralization, flocculation and sedimentation, screening and impurity removal, and hydrorefining. The acid-base neutralization and screening processes remove excess impurities from the lubricating oil. Hydrorefining involves introducing hydrogen gas into the lubricating oil, causing unsaturated hydrocarbons, alkenes, dienes, and aromatics to become saturated hydrocarbons, thus improving oil quality. During hydrorefining, sulfur, oxygen, and nitrogen in the lubricating oil are converted into hydrogen sulfide, water, and ammonia. Ammonia is recovered after being treated in an ammonia scrubbing tower, while hydrogen sulfide is initially treated as waste and discarded. However, hydrogen sulfide has excellent potential for waste utilization, as shown by the following chemical equation:

[0004] 2H₂S + 3O₂ = 2H₂O + 2SO₂ (when completely burned) - Equation 1

[0005] 2H₂S + O₂ = 2H₂O + 2S (incomplete combustion) - Equation 2

[0006] SO2 + H2O = H2SO3 (sulfate ion solution) - Equation 3

[0007] 2H2SO3+O2=H2SO4 (sulfuric acid solution)-Formula 4

[0008] According to Formulas 1 and 2, hydrogen sulfide reacts with oxygen to produce sulfur dioxide and sulfur. Sulfur, as a monomer, can be used to manufacture products with high economic efficiency, such as rubber, gunpowder, and sugar. Sulfur dioxide reacts with water and oxygen to produce sulfuric acid, which is a commonly used chemical with high efficiency. However, comparing Formulas 1 and 2, it can be seen that the environment required for the production of sulfuric acid or sulfur from hydrogen sulfide is different, namely, the degree of combustion and the amount of oxygen input are different. Therefore, sulfur dioxide gas and elemental sulfur will coexist in the reactor. Since water is produced when hydrogen sulfide burns, the water, elemental sulfur, and other impurities will mix and settle at the bottom of the reactor. When the reactor heats up, the water will evaporate, causing elemental sulfur and other impurities to mix and clump together at the bottom of the reactor, affecting the heat transfer efficiency of the reactor, thus affecting the production of sulfur dioxide, and even causing the reactor to explode due to uneven heat transfer. Summary of the Invention

[0009] The purpose of this invention is to solve the problem of separating the sulfur that has hardened on the bottom of the reactor from the bottom of the reactor, thereby avoiding the problems of affecting the heat transfer efficiency of the reactor, thus affecting the production of sulfur dioxide, or even causing the reactor to explode due to uneven heat transfer.

[0010] To achieve the above objectives, the present invention provides the following technical solution: an impurity filtration and separation device for lubricating oil production, comprising:

[0011] The reactor has an oxygen inlet, a hydrogen sulfide inlet, and a sulfur dioxide outlet on its outer side, and a vibration groove for accommodating a vibration mechanism is provided inside the reactor.

[0012] The vibration mechanism includes a motor, a rotating shaft, a vibration groove sealing gasket, a rack, and a striking mechanism. The motor is fixedly connected to the reactor, the rotating shaft is fixedly connected to the striking mechanism, the output end of the motor passes through the reactor and is fixedly connected to the rotating shaft, the rack is fixedly connected to the vibration groove, and the striking mechanism includes a striking box fixedly connected to the rotating shaft. A lead screw is rotated inside the striking box, and the lead screw is movably connected to the striking assembly through a lead screw nut. One end of the lead screw passes through the striking box and is fixedly connected to a bevel gear, which meshes with the rack.

[0013] As a further embodiment of the present invention: the striking assembly is provided with a striking plate, a striking post is bolted to one side of the striking plate, a sleeve is fixed to the side of the striking plate away from the striking post, a connecting rod is slidably connected inside the sleeve, a guide rod and a clamping mechanism are fixed to the connecting rod through an end seat, a replacement rail and a replacement seat are both movably connected to the guide rod, a replacement mechanism is provided on one side of the end seat, and replacement seats are provided on both sides of the replacement rail, and the replacement rail is movably connected to the replacement seat through a spring.

[0014] As a further embodiment of the present invention: both the replacement rail and the replacement seat have spring-loaded cavities for accommodating springs inside. The inner sidewall of the spring-loaded cavity has guide rod holes. The guide rod holes are connected to both ends of the replacement rail and the replacement seat. The guide rod holes are adapted to the guide rods, and the guide rods are engaged with the springs.

[0015] As a further embodiment of the present invention: the clamping mechanism includes a clamping bar, the clamping bar having a locking pin hole inside, and a locking pin being fixedly connected inside the striking pin, the locking pin being adapted to the locking pin hole.

[0016] As a further embodiment of the present invention: a connecting seat is fixedly connected inside the replacement seat.

[0017] As a further embodiment of the present invention: the vibration groove is slidably connected to the furnace seal, and a slanted cut is provided on one side of the clamping bar.

[0018] As a further embodiment of the present invention: the clamping bar is made of elastic metal, and the connecting seat is made of rubber.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The drive motor rotates forward and backward to drive the rotating shaft to swing, and the rotating shaft in turn drives the striking mechanism to swing. Since the striking mechanism is equipped with striking components, the striking components can be used to strike the bottom of the reactor during the swinging process of the striking mechanism, so as to remove the sulfur and impurities that have accumulated on the bottom of the reactor from the reactor, thereby avoiding affecting the heat transfer efficiency of the reactor, thus affecting the production of sulfur dioxide, or even causing the reactor to explode due to uneven heat transfer.

[0021] 2. The internal mechanism of the striking box is equipped with a lead screw, which is movably connected to the striking assembly via a lead screw nut. One end of the lead screw is fixed with a bevel gear, which meshes with a rack. The meshing of the bevel gear and rack causes the bevel gear to drive the lead screw to rotate, which in turn drives the lead screw nut and the striking assembly to move along the lead screw axis. This strengthens the striking force of the striking assembly on the bottom wall of the reactor and improves the striking effect on the bottom wall of the reactor.

[0022] 3. Since the striking components will inevitably be damaged during the striking process due to the absorption of striking energy, and replacing the striking post separately requires unscrewing the bolts from inside the striking plate, it is inconvenient. Therefore, by holding the connecting rod, one end of the connecting rod can be disengaged from the insert. As the connecting rod disengages from the insert, it will simultaneously disengage from the replacement mechanism, leaving the replacement rail, replacement seat, and spring in a relaxed state. After removing and replacing the spring from inside the spring clip cavity, the guide rod is inserted into the replacement rail and replacement seat to clamp the replacement rail, replacement seat, and spring together, and at the same time, the clamping mechanism is clamped together with the locking post. Then, the connecting rod is inserted into the insert, thus completing the repair and replacement of the striking components. All springs can be replaced in one go, making replacement convenient.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0036] Please refer to this carefully. Figure 10 In the production process of lubricating oil, it is necessary to go through a series of steps: acid-base neutralization, flocculation and sedimentation, screening and impurity removal, and hydrorefining. The acid-base neutralization and screening processes are all steps to remove excess impurities from the lubricating oil. Hydrorefining involves introducing hydrogen gas into the lubricating oil, causing unsaturated hydrocarbons, alkenes, dienes, and aromatics to become saturated hydrocarbons, thereby improving oil quality. Furthermore, during hydrorefining, sulfur, oxygen, and nitrogen in the lubricating oil are converted into hydrogen sulfide, water, and ammonia. Ammonia is recovered after being treated in an ammonia scrubbing tower, while hydrogen sulfide is initially treated as waste and discarded. However, hydrogen sulfide has excellent potential for waste utilization, as shown by the following chemical equation:

[0037] 2H₂S + 3O₂ = 2H₂O + 2SO₂ (when completely burned) - Equation 1

[0038] 2H₂S + O₂ = 2H₂O + 2S (incomplete combustion) - Equation 2

[0039] SO2 + H2O = H2SO3 (sulfate ion solution) - Equation 3

[0040] 2H2SO3+O2=H2SO4 (sulfuric acid solution)-Formula 4

[0041] According to Formulas 1 and 2, hydrogen sulfide reacts with oxygen to produce sulfur dioxide and sulfur. Sulfur, as a monomer, can be used to manufacture products with high economic efficiency, such as rubber, gunpowder, and sugar. Sulfur dioxide reacts with water and oxygen to produce sulfuric acid, which is a commonly used chemical with high efficiency. However, comparing Formulas 1 and 2, it can be seen that the environment required for hydrogen sulfide to produce sulfuric acid or sulfur is different, namely, the degree of combustion and the amount of oxygen input are different. Therefore, sulfur dioxide gas and elemental sulfur will coexist in the reactor. Since water is produced when hydrogen sulfide burns, the water, elemental sulfur, and other impurities will mix and settle at the bottom of reactor 1. When reactor 1 is heated, the water will evaporate, causing elemental sulfur and other impurities to mix and clump together at the bottom of reactor 1, affecting the heat transfer efficiency of reactor 1, thus affecting the production of sulfur dioxide, and even causing the reactor to explode due to uneven heat transfer.

[0042] Please see Figures 1-8 In this embodiment of the invention, the impurity filtration and separation device for lubricating oil production includes:

[0043] The reactor 1 has an oxygen inlet 12, a hydrogen sulfide inlet 13, and a sulfur dioxide outlet 14 on its outer side. The hydrogen sulfide solution can be connected to the hydrogen sulfide inlet 13 after the hydrogen sulfide gas is produced, and the oxygen inlet 12 and the sulfur dioxide outlet 14 can be connected to the external pipeline at the same time, so that the oxygen inlet 12 can be filled with oxygen, the hydrogen sulfide inlet 13 can be filled with hydrogen sulfide solution, and the sulfur dioxide outlet 14 can output sulfur dioxide. The reactor 1 has a vibration tank 15 that houses the vibration mechanism 2. Because water is produced when hydrogen sulfide is burned, the water, elemental sulfur, and other impurities will settle to the bottom of the reactor 1 after mixing. When the reactor 1 is heated up, the water will evaporate, causing the elemental sulfur and other impurities to mix and clump together at the bottom of the reactor 1. The bottom of the reactor 1 can be vibrated by the vibration mechanism 2.

[0044] The vibration mechanism 2 includes a motor 21, a rotating shaft 22, a vibration groove sealing gasket 23, a rack 24, and a striking mechanism 3. The motor 21 is fixedly connected to the reactor 1, the rotating shaft 22 is fixedly connected to the striking mechanism 3, and the output end of the motor 21 passes through the reactor 1 and is fixedly connected to the rotating shaft 22. The rack 24 is fixedly connected to the vibration groove 15. The striking mechanism 3 includes a striking box 31 fixedly connected to the rotating shaft 22. The motor 21 drives the rotating shaft 22 to swing by rotating forward and backward, and the rotating shaft 22 in turn drives the striking mechanism 3 to swing. Since the striking mechanism 3 contains a striking component 5, and the striking box 31 contains a lead screw 32, which is movably connected to the striking component 5 through a lead screw nut 34, and one end of the lead screw 32 is fixedly connected to a bevel gear 33, which meshes with the rack 24, the striking mechanism 3 swings... During the process, the striking component 5 can be used to strike the bottom of the reactor 1 to remove the sulfur and impurities that have hardened on the bottom of the reactor 1 from the reactor 1. One end of the lead screw 32 passes through the striking box 31 and is fixedly connected to a bevel gear 33. The bevel gear 33 meshes with the rack 24, and the bevel gear 33 also meshes with the rack 24. Therefore, during the swinging process of the striking mechanism 3, the striking component 5 can be used to strike the bottom of the reactor 1 to remove the sulfur and impurities that have hardened on the bottom of the reactor 1 from the reactor 1. At the same time, the meshing connection between the bevel gear 33 and the rack 24 causes the bevel gear 33 to drive the lead screw 32 to rotate. The lead screw 32 then drives the lead screw nut 34 and the striking component 5 to move along the axial direction of the lead screw 32, thereby increasing the force of the striking component 5 striking the bottom wall of the reactor 1 and improving the striking effect of the bottom wall of the reactor 1.

[0045] As a further embodiment of the present invention: the striking assembly 5 is provided with a striking plate 51, a striking post 55 is bolted to one side of the striking plate 51, and a sleeve 52 is fixed to the side of the striking plate 51 away from the striking post 55. A connecting rod 53 is slidably connected inside the sleeve 52. The connecting rod 53 is fixed to a guide rod 6 and a clamping mechanism 9 through an end seat 54. The replacement rail 81 and the replacement seat 82 are both movably connected to the guide rod 6. A replacement mechanism 8 is provided on one side of the end seat 54. Replacement seats 82 are provided on both sides of the replacement rail 81. The replacement rail 81 is movably connected to the replacement seat 82 through a spring 7. Since the striking assembly 5 will always be damaged when absorbing the striking energy during the striking process, and it is inconvenient to unscrew the bolt from the striking plate 51 to replace the striking post 55 alone, one end of the connecting rod 53 can be dislodged from the sleeve 52 by holding the connecting rod 53. In the process of dislodging the connecting rod 53 from the sleeve 52, it will also dislodge from the inside of the replacement mechanism 8.

[0046] As a further embodiment of the present invention: both the replacement rail 81 and the replacement seat 82 have spring clip cavities 84 for accommodating the spring 7 inside. The inner sidewall of the spring clip cavity 84 has a guide rod hole 61. The guide rod hole 61 is connected to both ends of the replacement rail 81 and the replacement seat 82. The guide rod hole 61 is adapted to the guide rod 6. The guide rod 6 is engaged with the spring 7. Since the connecting rod 53 is fixed to the guide rod 6 through the end seat 54 and fixed to the clamping mechanism 9 through the end seat 54, the guide rod 6 will gradually disengage from the guide rod hole 61 inside the replacement rail 81 and the replacement seat 82 during the disengagement process. When the guide rod 6 moves into the spring clip cavity 84, it will disengage from the spring 7 until the guide rod 6 is completely disengaged from the guide rod hole 61.

[0047] As a further embodiment of the present invention: the clamping mechanism 9 includes a clamping bar 91, the clamping bar 91 has a locking post hole 92 inside, and a locking post 56 is fixedly connected inside the striking post 55. The locking post 56 is adapted to the locking post hole 92. During the process of the guide rod 6 disengaging from the guide rod hole 61, the clamping mechanism 9 will also disengage from the locking post 56. Furthermore, the clamping mechanism 9 will also disengage from the locking post 56 after the guide rod 6 has completely disengaged from the guide rod hole 61.

[0048] As a further aspect of the present invention: a connecting seat 83 is fixedly connected inside the replacement seat 82. The connecting seat 83 is made of rubber and can improve the striking effect of the replacement mechanism 8.

[0049] As a further embodiment of the present invention: the vibration groove is slidably connected to the furnace seal, and a beveled cut 93 is provided on one side of the clamping bar 91. The clamping bar 91 is made of elastic metal, and the beveled cut 93 facilitates the movement of the clamping bar 91 and facilitates the connection between the clamping bar 91 and the locking post 56.

[0050] The working principle of this invention is: based on Figure 10As shown, the lubricating oil first undergoes a series of processes including acid-base neutralization, flocculation sedimentation, and sieving to remove impurities. The acid-base neutralization and sieving processes remove excess impurities from the lubricating oil, resulting in a pH value that is weakly acidic or neutral and impurities that are no longer visible to the naked eye. The lubricating oil is then fed into a hydrorefining process. By introducing hydrogen gas into the lubricating oil, unsaturated hydrocarbons, olefins, dienes, and aromatics are hydrogenated to saturate hydrocarbons, thus improving the quality of the lubricating oil. During hydrorefining, sulfur, oxygen, and nitrogen in the lubricating oil are converted into hydrogen sulfide, water, and ammonia. Hydrogen sulfide and water dissolve in water to form a mixture of hydrogen sulfide solution and ammonia solution, while the ammonia is treated in an ammonia scrubbing tower. After treatment, the hydrogen sulfide solution is recovered. The hydrogen sulfide gas is then connected to the hydrogen sulfide interface 13, and simultaneously the oxygen interface 12 and sulfur dioxide outlet 14 are connected to external pipelines. This allows oxygen to be introduced into the oxygen interface 12, hydrogen sulfide solution to be introduced into the hydrogen sulfide interface 13, and sulfur dioxide to be output from the sulfur dioxide outlet 14. The mixture is then ignited inside the reactor 1, causing the hydrogen sulfide to react and produce sulfur dioxide and elemental sulfur. Because water is produced during the combustion of hydrogen sulfide, the water, elemental sulfur, and other impurities mix and settle at the bottom of the reactor 1. As the reactor 1 heats up, the water evaporates, causing the elemental sulfur and other impurities to mix and solidify at the bottom of the reactor 1. At this point, the drive motor 21 rotates in both directions, causing the rotating shaft 22 to swing. This causes the striking mechanism 3 to swing. Since the striking mechanism 3 contains a striking component 5, and one end of the lead screw 32 is fixedly connected to a bevel gear 33, which in turn meshes with the rack 24, the striking mechanism 3 can, during its swing, strike the bottom of the reactor 1 using the striking component 5 to remove the sulfur and impurities deposited on the bottom of the reactor 1. Simultaneously, the meshing of the bevel gear 33 and rack 24 causes the lead screw 32 to rotate, which in turn drives the lead screw nut 34 and the striking component 5 to move axially along the lead screw 32, increasing the force of the striking component 5 striking the bottom wall of the reactor 1. However, since the striking component 5 will inevitably be damaged during the striking process, and replacing the striking column 55 alone requires… It is inconvenient to unscrew the bolt from the striking plate 51. Therefore, one end of the connecting rod 53 can be disengaged from the insert 52 by holding the connecting rod 53. During the disengagement of the connecting rod 53 from the insert 52, it will simultaneously disengage from the replacement mechanism 8. The specific disengagement process is as follows: Since the connecting rod 53 is fixed to the guide rod 6 through the end seat 54 and to the clamping mechanism 9 through the end seat 54, the guide rod 6 will gradually disengage from the guide rod hole 61 inside the replacement rail 81 and the replacement seat 82 during the disengagement process. When the guide rod 6 moves into the spring clip cavity 84, it will disengage from the spring 7 until the guide rod 6 is completely disengaged from the guide rod hole 61. At the same time, during the disengagement of the guide rod 6 from the guide rod hole 61, the clamping mechanism 9 will also disengage from the locking post 56.Furthermore, the clamping mechanism 9 will also disengage from the locking post 56 after the guide rod 6 has completely disengaged from the guide rod hole 61. At this time, the replacement rail 81, replacement seat 82, and spring 7 are in a relaxed state. After replacing the spring 7 inside the spring retaining cavity 84, the guide rod 6 is inserted into the replacement rail 81 and replacement seat 82 to lock the replacement rail 81, replacement seat 82, and spring 7 together, and simultaneously the clamping mechanism 9 is locked together with the locking post 56. Then, the connecting rod 53 is inserted into the insert 52, thus completing the repair and replacement of the striking assembly 5.

[0051] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
