Description

Technical Field

[0001] The present invention relates to the petrochemical field, and specifically to a petrochemical electrical automatic control stirring device. Background Art

[0002] The petrochemical industry, namely petrochemical, refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. Petroleum products include various fuel oils (such as gasoline, kerosene, diesel, etc.), lubricating oils, as well as paraffin wax, asphalt, etc.; Petrochemical products are a variety of organic chemicals produced through a series of chemical reactions using light hydrocarbons, olefins, aromatics, etc. in petroleum and natural gas as raw materials, such as plastics, synthetic rubbers, synthetic fibers, chemical fertilizers, and many fine chemical products. Hydrogenation reaction plays a crucial role in the petrochemical industry and is closely related to all aspects of petrochemical. In the midstream refining link of the petrochemical industrial chain, the hydrogenation reaction is one of the core processes to improve the quality of oil products. Crude oil usually contains impurities such as sulfur, nitrogen, oxygen, and a large amount of unsaturated hydrocarbons. Through hydrogenation desulfurization, hydrogenation denitrification, hydrogenation deoxidation and other reactions, these impurities can be effectively removed to avoid the generation of harmful gas emissions during the combustion of oil products and pollute the environment. At the same time, hydrogenating the unsaturated hydrocarbons can improve the stability and combustion performance of the oil products. For example, in diesel production, hydrogenation treatment can reduce the sulfur content of diesel, increase the cetane number, make the diesel burn more fully, reduce particulate matter and nitrogen oxides emissions in the tail gas, and meet the increasingly strict environmental protection standards. In the petrochemical production process, the hydrogenation reaction is indispensable. And during the hydrogenation reaction process, mixing and promoting chemical reactions are often required. The structure of traditional stirring equipment is often relatively complex, with numerous internal components, which not only increases the manufacturing cost of the equipment but also greatly improves the maintenance difficulty of the equipment. In terms of the stirring function, conventional stirring equipment only relies on simple stirring blades and is difficult to achieve full mixing of the liquid in the reaction tank, resulting in uneven mixing of materials and seriously affecting product quality. Moreover, due to the lack of effective auxiliary components, the reaction efficiency is low. In order to achieve the desired reaction effect, it is necessary to extend the reaction time or increase the input amount of reactants, which undoubtedly increases the production cost. At the same time, during the operation of existing stirring equipment, the equipment is severely damaged. The frequent friction between the stirring components and the materials not only shortens the service life of the equipment but also increases the maintenance frequency of the equipment. In addition, due to incomplete reactions, a large amount of unreacted substances will be generated, and these substances are discharged into the environment, causing serious pollution, which does not conform to the current environmental protection development trend. Therefore, it is extremely urgent to develop a stirring equipment with a simple structure, which can achieve full mixing, improve the reaction efficiency, reduce equipment loss, and reduce pollution emissions.

[0019] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0020] Embodiment 1: Please refer to Figure 1 、 Figure 2 and Figure 3, A petrochemical electrical automatic control stirring device, including an equipment support 1, on which a reaction tank body 2 is installed. At the inner top of the reaction tank body 2, there is an installation base plate 3, which can be directly welded to the inner wall of the reaction tank body 2 or can be detachably connected to the reaction tank body 2 through bolts. A motor 4 is fixedly connected to the installation base plate 3, and a protective cover can be set outside the motor 4 as required to reduce corrosion and improve durability. A central shaft 5 is fixedly connected to the rotor of the motor 4. A stirring vertical plate 6 is fixedly connected to the outside of the central shaft 5. A spiral blade 7 located below the stirring vertical plate 6 is connected below the central shaft 5. A stirring auxiliary component 8 driven by the central shaft 5 is fixedly connected to the side wall of the reaction tank body 2, and the stirring auxiliary component 8 reciprocates longitudinally along the axis of the central shaft 5; An air inlet pipe 9 is connected to the side of the reaction tank body 2, and a gas distributor 10 is connected inside the air inlet pipe 9. The gas distributor 10 changes the exhaust position through the central shaft 5. A feed pipe 11 is connected to the bottom of the reaction tank body 2, a discharge pipe 12 is connected above the side of the reaction tank body 2, an exhaust pipe 13 is connected to the top of the reaction tank body 2, and a partition net 14 is connected below the inner wall of the reaction tank body 2. The partition net 14 is used to isolate the catalyst and form a catalyst bed above the partition net 14 to facilitate the efficient progress of the reaction.

[0021] First, install and debug the equipment. Hydrogen is introduced into the air inlet pipe 9 and petrochemical raw materials are introduced into the feed pipe 11. In addition, a catalyst needs to be added to the equipment and other reaction conditions for the hydrogenation reaction need to be met. At this time, the hydrogenation reaction can be carried out. According to the requirements of the reaction, the motor 4 is started. The rotation of the motor 4 drives the rotation of the central shaft 5, and the rotation of the central shaft 5 drives the rotation of the stirring vertical plate 6, so that the contact sufficiency between the petrochemical raw materials and hydrogen can be improved. While the stirring vertical plate 6 rotates for mixing, the stirring auxiliary component 8 moves under the drive of the central shaft 5 to assist the stirring vertical plate 6 in mixing the materials. After hydrogen enters the interior of the reaction tank body 2, it enters the gas distributor 10, and after being discharged through the gas distributor 10, it can be more evenly distributed in the reaction tank body 2, thereby improving the mixing sufficiency.

[0022] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , The stirring auxiliary component 8 includes a rotating shaft connecting plate 15 rotatably connected to the central shaft 5. A side rotating shaft 16 is rotatably connected below the rotating shaft connecting plate 15. A displacement driving block 17 is threadedly connected to the outside of the side rotating shaft 16. A stirring unit 18 is connected to the side of the displacement driving block 17 facing the stirring vertical plate 6. The stirring unit 18 is longitudinally slidably connected to the stirring vertical plate 6, and the side rotating shaft 16 is driven to rotate by a driving unit 19. A tilted stirring plate 26 is connected to the side of the displacement driving block 17 away from the stirring vertical plate 6.

[0023] During the rotation of the side rotating shaft 16, the displacement driving block 17 is driven to move up and down to adjust the stirring position, and during the rotation of the central shaft 5, the side rotating shaft 16 and the displacement driving block 17 can be driven to rotate synchronously through the stirring unit 18. An inclined stirring plate 26 is also provided on the outer side of the displacement driving block 17. The inclined stirring plate 26 can also improve the mixing adequacy during the synchronous rotation process.

[0024] The stirring unit 18 includes a transverse shaft 20 rotatably connected to the displacement driving block 17, an inclination adjustment plate 21 is fixedly connected to the outer side of the transverse shaft 20, a slide groove 22 is provided on the stirring vertical plate 6, a connecting frame 23 is slidably connected inside the slide groove 22, the transverse shaft 20 is rotatably connected to the connecting frame 23, a direction-changing gear 24 is fixedly connected to the end of the transverse shaft 20, a rack 25 is fixedly connected to the outer side of the stirring vertical plate 6, and the rack 25 cooperates with the direction-changing gear 24.

[0025] Since the transverse shaft 20 is rotatably connected with the displacement drive block 17, the direction-changing gear 24 can be driven to move up and down during the up and down movement. During the up and down movement of the direction-changing gear 24, due to the meshing with the rack 25, it will rotate along its own axis when moving up and down, and drive the tilt adjustment plate 21 to change the inclination angle. Since the tilt adjustment plate 21 rotates along the central axis 5, the changing inclination angle can continuously change the mixing effect, making the reaction more sufficient. The direction-changing gear 24 meshes with the rack 25 during the up and down movement, and the rack 25 can also be provided with gaps at intervals, so that the direction-changing gear 24 will not rotate under the action of the rack 25 at this position, thereby realizing the complex and variable stirring of the stirring unit 18.

[0026] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 A petrochemical electrical automatic control stirring device comprises an equipment support 1, a reaction tank body 2 is mounted on the equipment support 1, a mounting base plate 3 is connected to the top of the inner side of the reaction tank body 2, a motor 4 is fixedly connected to the mounting base plate 3, a central shaft 5 is fixedly connected to the rotor of the motor 4, a stirring plate 6 is fixedly connected to the outer side of the central shaft 5, a spiral blade 7 located below the stirring plate 6 is connected below the central shaft 5, a stirring auxiliary component 8 driven by the central shaft 5 is fixedly connected to the side wall of the reaction tank body 2, and the stirring auxiliary component 8 reciprocates longitudinally along the axis of the central shaft 5; an air inlet pipe 9 is connected to the side of the reaction tank body 2, a gas distributor 10 is connected inside the air inlet pipe 9, and the gas distributor 10 changes the exhaust position through the central shaft 5. A feed pipe 11 is connected to the bottom of the reaction tank body 2, a discharge pipe 12 is connected to the top of the side of the reaction tank body 2, an exhaust pipe 13 is connected to the top of the reaction tank body 2, and a partition net 14 is connected to the bottom of the inner wall of the reaction tank body 2.

[0027] First, install and debug the equipment. Introduce hydrogen into the intake pipe 9 and introduce petrochemical raw materials into the feed pipe 11. In addition, a catalyst needs to be added to the equipment and other reaction conditions for the hydrogenation reaction need to be met. At this time, the hydrogenation reaction can be carried out. Start the motor 4 according to the reaction requirements. The rotation of the motor 4 drives the central shaft 5 to rotate. The rotation of the central shaft 5 drives the stirring vertical plate 6 to rotate, so that the contact sufficiency between the petrochemical raw materials and hydrogen can be improved. While the stirring vertical plate 6 rotates for mixing, the stirring auxiliary assembly 8 moves driven by the central shaft 5 to assist the stirring vertical plate 6 in mixing the materials. After the hydrogen enters the inside of the reaction tank body 2, it enters the gas distributor 10 and can be more evenly distributed inside the reaction tank body 2 after being discharged through the gas distributor 10, thereby improving the mixing sufficiency.

[0028] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 , the stirring auxiliary assembly 8 includes a rotating shaft connecting plate 15 rotatably connected to the central shaft 5. A side rotating shaft 16 is rotatably connected below the rotating shaft connecting plate 15. A displacement driving block 17 is threadedly connected to the outside of the side rotating shaft 16. A stirring unit 18 is connected to the side of the displacement driving block 17 facing the stirring vertical plate 6. The stirring unit 18 is longitudinally slidably connected to the stirring vertical plate 6. The side rotating shaft 16 is driven to rotate by a driving unit 19. An inclined stirring plate 26 is connected to the side of the displacement driving block 17 away from the stirring vertical plate 6.

[0029] During the rotation of the side rotating shaft 16, the displacement driving block 17 moves up and down to adjust the stirring position. During the rotation of the central shaft 5, the side rotating shaft 16 and the displacement driving block 17 can be driven to rotate synchronously through the stirring unit 18. An inclined stirring plate 26 is also provided on the outside of the displacement driving block 17. During the synchronous rotation of the inclined stirring plate 26, the mixing sufficiency can also be improved.

[0030] The stirring unit 18 includes a transverse shaft 20 rotatably connected to the displacement driving block 17. An inclined adjusting plate 21 is fixedly connected to the outside of the transverse shaft 20. A chute 22 is opened on the stirring vertical plate 6. A connecting frame 23 is slidably connected inside the chute 22. The transverse shaft 20 is rotatably connected to the connecting frame 23. A direction-changing gear 24 is fixedly connected to the end of the transverse shaft 20. A rack 25 is fixedly connected to the outside of the stirring vertical plate 6. The rack 25 is matched with the direction-changing gear 24. Two racks 25 are provided, respectively located on both sides of the direction-changing gear 24. The direction-changing gear 24 only meshes with one side rack 25 during the up and down movement.

[0031] Since the horizontal axis 20 is rotatably connected to the displacement driving block 17, it can drive the direction-changing gear 24 to move up and down during the up-and-down movement. During the up-and-down movement of the direction-changing gear 24, due to meshing with the rack 25, it will rotate around its own axis during the up-and-down movement and drive the tilt adjustment plate 21 to change the tilt angle. Since the tilt adjustment plate 21 rotates along the central axis 5, changing the tilt angle can continuously change the mixing effect, making the reaction more sufficient. The rack 25 can be provided only on one side or, as shown in Figure 7 , there can be two symmetrically arranged ones. During the up-and-down movement of the direction-changing gear 24, it can only mesh with the rack 25 on one side, and notches can also be arranged at intervals on the rack 25, so that the direction-changing gear 24 will not rotate under the action of the rack 25 at this position, thus realizing the complexity and variability of the stirring of the stirring unit 18.

[0032] Please refer to Figure 6 . The driving unit 19 includes a driving gear 27 fixedly connected to the outside of the side rotating shaft 16. An electric telescopic rod 28 is connected below the mounting substrate 3, and a toothed ring 29 is fixedly connected to the bottom of the electric telescopic rod 28. During the up-and-down movement of the toothed ring 29, it meshes with the driving gear 27. The structural setting of the driving unit 19 is one of the core improvements of the present invention. It forms an integral whole with the above structure. During the telescopic movement of the electric telescopic rod 28, the toothed ring 29 moves up and down. The up-and-down movement of the toothed ring 29 can synchronously drive the side rotating shaft 16 to rotate, realizing the position adjustment of the stirring unit 18. When the electric telescopic rod 28 drives the toothed ring 29 to disengage from the driving gear 27, the side rotating shaft 16 will synchronously rotate along with the central axis 5 and will not rotate itself to drive the stirring unit 18 to move up and down. Both cooperation states can achieve different mixing effects. And a toothless part can be provided on the toothed ring 26. When the driving gear 27 moves to this toothless part, it will also stop rotating, thereby changing the stirring state. The driving unit can also directly set an additional motor on the rotating shaft connecting plate 15 to realize the rotational drive of the side rotating shaft 16. Although the adjustment of the side rotating shaft 16 can also be realized, the cost of the motor is significantly higher than that of the electric telescopic rod 28, and this motor needs to rotate synchronously with the turnover of the side rotating shaft 16, and a more complex power supply structure is required to avoid the entanglement of wires.

[0033] Please refer to Figure 8 and Figure 9, the gas distributor 10 includes a main pipeline 30. The inner end of the intake pipe 9 is connected with a sleeve 31, and the sleeve 31 communicates with the main pipeline 30. The central shaft 5 passes through the sleeve 31 to drive the main pipeline 30 to rotate. The side of the main pipeline 30 is communicated with exhaust branch pipes 32, and air holes 33 are evenly distributed on the side walls of the exhaust branch pipes 32. The structural setting of the gas distributor 10 can also further increase the sufficiency of the reaction on the premise of sufficient stirring. The central shaft 5 passes through the sleeve 31 to drive the main pipeline 30 and the exhaust branch pipes 32 to rotate, and the exhaust position will continuously change during rotation. The central shaft 5 passing through the sleeve 31 can drive the main pipeline 30 to rotate. At this time, the technical means for the gas inside the intake pipe 9 to enter the main pipeline 30 is the prior art. Only a sealing structure needs to be set between the two ends of the sleeve 31 and the central shaft 5, and then the end of the central shaft 5 is hollow and communicates with the intake pipe 9 and the main pipeline 30 at the same time. The technical means for achieving sealing during rotation is the prior art, and the sealing requirement of this application is not high. Even if there is gas leakage, it does not affect the normal progress of the reaction.

[0034] A plurality of arc-shaped protrusions 34 are fixedly connected to the inner wall of the reaction tank body 2. A transverse moving rod 35 is slidably connected to the inner side of the exhaust branch pipe 32. The transverse moving rod 35 abuts against the arc-shaped protrusion 34 under the action of a spring 36. A blocking block 37 for blocking the air hole 33 is fixedly connected to the outer side of the transverse moving rod 35. Since the exhaust branch pipe 32 rotates continuously, the transverse moving rod 35 abuts against the arc-shaped protrusion 34 under the elastic force of the spring 36, and the relative position thereof continuously changes relative to the exhaust branch pipe 32, thereby driving the blocking block 37 to continuously change its position. When cooperating with different air holes 33, the exhaust becomes more disorderly, further ensuring the effect of the hydrogenation reaction. The arc-shaped protrusions 34 can be set as required, as long as they can drive the transverse moving rod 35 to generate a relative position change without hindering the rotation of the transverse moving rod 35.

[0035] A plurality of mounting rings 38 are fixedly connected to the outer side of the reaction tank body 2, and the reaction tank body 2 is fixed through the mounting rings 38 between devices.

[0036] Working principle: First, install and debug the equipment. Hydrogen is introduced into the intake pipe 9 and petrochemical raw materials are introduced into the feed pipe 11. In addition, a catalyst needs to be added to the equipment and other reaction conditions for the hydrogenation reaction are met. At this time, the hydrogenation reaction can be carried out. The motor 4 is started according to the reaction requirements. The motor 4 rotates to drive the central shaft 5 to rotate, and the central shaft 5 rotates to drive the stirring vertical plate 6 to rotate, so that the contact sufficiency between the petrochemical raw materials and hydrogen can be improved. While the stirring vertical plate 6 rotates for mixing, the stirring auxiliary assembly 8 moves under the drive of the central shaft 5 to assist the stirring vertical plate 6 in mixing the materials. After the hydrogen enters the reaction tank body 2, it enters the gas distributor 10, and after being discharged through the gas distributor 10, it can be more evenly distributed inside the reaction tank body 2, thereby improving the sufficiency of mixing.

[0037] During the rotation of the side rotating shaft 16, it drives the displacement driving block 17 to move up and down to adjust the position of stirring. During the rotation of the central shaft 5, it can drive the side rotating shaft 16 and the displacement driving block 17 to rotate synchronously through the stirring unit 18. An inclined stirring plate 26 is also arranged outside the displacement driving block 17, and the sufficiency of mixing can also be improved during the synchronous rotation of the inclined stirring plate 26.

[0038] Since the transverse shaft 20 is rotationally connected to the displacement driving block 17, it can drive the direction-changing gear 24 to move up and down during the up-and-down movement. During the up-and-down movement of the direction-changing gear 24, due to meshing with the rack 25, it will rotate around its own axis during the up-and-down movement and drive the inclined adjusting plate 21 to change the inclination angle. Since the inclined adjusting plate 21 rotates along the central shaft 5, changing the inclination angle can continuously change the mixing effect and make the reaction more sufficient. The rack 25 can be arranged on only one side or, as Figure 7 shown, there can be two symmetrically arranged ones. During the up-and-down movement of the direction-changing gear 24, it can only mesh with the rack 25 on one side, and notches can also be arranged at intervals on the rack 25, so that the direction-changing gear 24 will not rotate under the action of the rack 25 at this position, thus realizing the complexity and variability of the stirring of the stirring unit 18.

[0039] The structural setting of the gas distributor 10 can also further increase the sufficiency of the reaction on the premise of sufficient stirring. The central shaft 5 penetrates through the sleeve 31 to drive the main pipe 30 and the exhaust branch pipe 32 to rotate. When rotating, the exhaust position will continuously change. At the same time, due to the continuous rotation of the exhaust branch pipe 32, the transverse moving rod 35 abuts against the arc-shaped protrusion 34 under the elastic force of the spring 36, and its relative position with respect to the exhaust branch pipe 32 continuously changes, thus driving the blocking block 37 to continuously displace. When cooperating with different air holes 33, the exhaust also becomes more disordered, further ensuring the effect of the hydrogenation reaction. The arc-shaped protrusion 34 can be set as required, as long as it can drive the transverse moving rod 35 to generate a relative position change without hindering the rotation of the transverse moving rod 35.
