Description

Technical Field

[0001] This invention belongs to the field of heavy oil viscosity reduction technology, and particularly relates to a mixing apparatus and method for processing heavy oil viscosity reducers. Background Technology

[0002] Heavy oil has a high content of gum and asphaltenes, and its viscosity at room temperature can be hundreds to thousands of times that of conventional crude oil, resulting in high extraction costs and low efficiency. Heavy oil viscosity reducers, as the core of chemical viscosity reduction technology, significantly reduce flow resistance by changing the intermolecular forces or emulsification state of crude oil, and have become a key means to improve the recovery rate of heavy oil.

[0003] Existing technologies disclose several invention patents in the field of heavy oil viscosity reduction. Among them, patent CN113244847B discloses a two-stage blending and batching device for producing heavy oil viscosity reducers. This device includes a primary mixing tank, a secondary mixing tank, a spiral feed tank, a premixing tank, and a discharge tank. A dispersing and feeding mechanism is connected through the top wall of the primary mixing tank, and two sets of symmetrical primary stirring components are arranged on the bottom wall. Secondary stirring components are arranged between the inner side walls of the secondary mixing tank. A guide pipe assembly is provided between the primary mixing tank, premixing tank, and discharge tank to evenly pour materials into the primary mixing tank. The materials are dispersed into the primary mixing tank through multiple feeding holes in the feeding cylinder and the dispersing pipe, improving the fluidity of the materials during stirring within the primary mixing tank, thereby improving the primary mixing efficiency. However, this technical solution still has some shortcomings in its application. In the preparation process of heavy oil viscosity reducers, two core issues pose a serious threat to production efficiency and product quality. The first is the adhesion of high-viscosity products. The high-viscosity products generated after the reaction of raw materials are very easy to adhere to the surface of the stirring mechanism, which will destroy the uniformity of the stirring system, resulting in insufficient and uneven stirring, and ultimately causing a significant drop in overall output. The second is the condensation problem caused by uneven temperature distribution in the reactor. When the high-viscosity products come into contact with the low-temperature stirring mechanism during stirring, they will quickly condense on the surface of the stirring mechanism due to the sudden temperature change. These condensates are hard and tightly attached, making them extremely difficult to clean. Long-term accumulation will interfere with the operation of the stirring mechanism, reduce stirring efficiency, form a vicious cycle, and continuously damage the preparation of heavy oil viscosity reducers.

[0004] Based on this, the present invention designs a mixing apparatus and method for processing heavy oil viscosity reducers to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address two core issues in the preparation process of heavy oil viscosity reducers that seriously threaten production efficiency and product quality. First, there is the problem of high-viscosity product adhesion. High-viscosity products generated after the raw material reaction easily adhere to the surface of the stirring mechanism, disrupting the uniformity of the stirring system, leading to insufficient and uneven stirring, ultimately causing a significant drop in overall yield. Second, there is the problem of condensation caused by uneven temperature distribution in the reactor. When high-viscosity products come into contact with the low-temperature stirring mechanism during stirring, they rapidly condense on the surface of the stirring mechanism due to the sudden temperature change. These condensates are hard and tightly adhered, making them extremely difficult to clean. Long-term accumulation interferes with the operation of the stirring mechanism, reduces stirring efficiency, and creates a vicious cycle that continuously damages the preparation of heavy oil viscosity reducers. Therefore, this invention proposes a mixing device and method for processing heavy oil viscosity reducers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A mixing device for processing heavy oil viscosity reducers includes a frame, a control panel mounted on the top of the frame, a mixing mechanism fitted inside the frame, a reaction vessel fitted inside the frame, an inner liner fitted inside the reaction vessel, a combination port at the bottom of the reaction vessel, a discharge pipe fitted inside the combination port, one end of the discharge pipe being snapped into the bottom of the inner liner, a first valve installed at the other end of the discharge pipe, a spiral groove on the outer wall of the inner liner, a water inlet pipe snapped into the bottom end of the outer wall of the reaction vessel corresponding to the spiral groove, a second valve installed at the other end of the water inlet pipe, and a reflux hole on the outer wall of the reaction vessel corresponding to the top end of the spiral groove.

[0008] The top of the reactor is connected to the inner liner via a stirring mechanism, and a water bath heating mechanism is provided between the stirring mechanism and the mixing mechanism.

[0009] As a further description of the above technical solution:

[0010] The stirring mechanism includes a vessel cover connected to the top of the reactor. A first adapter hole is provided on the top of the vessel cover, and a stirring shaft is rotatably connected in the first adapter hole. A second adapter hole is provided at the bottom of the discharge pipe, and the other end of the stirring shaft is rotatably connected in the second adapter hole.

[0011] As a further description of the above technical solution:

[0012] An electric motor is installed on the top of the vessel lid. The output shaft of the electric motor is connected to the top of the stirring shaft. The top of the stirring shaft has a plurality of first water inlets arranged in a ring array, and the bottom of the stirring shaft has a plurality of second water inlets arranged in a ring array.

[0013] As a further description of the above technical solution:

[0014] The water bath heating mechanism includes two second sealed bearings fitted onto the bottom end of the stirring shaft. The two second sealed bearings are located on both sides of the second water inlet. The outer walls of the two second sealed bearings are fitted with the same second adapter sleeve. The outer wall of the second adapter sleeve is clamped with a suction pipe. A water pump is provided on the inner side of the frame. The other end of the suction pipe is connected to the inlet of the water pump. The outlet of the water pump is connected to a pressure relief pipe. The other end of the pressure relief pipe is connected to the other end of the water inlet pipe.

[0015] As a further description of the above technical solution:

[0016] The stirring shaft is fitted with a first sealing bearing on both sides corresponding to the first water inlet hole. The same first adapter sleeve is fitted on the two first sealing bearings. A return pipe is snapped onto the first adapter sleeve, and the other end of the return pipe is snapped into the return hole.

[0017] As a further description of the above technical solution:

[0018] The stirring shaft has multiple sets of rotating interfaces arranged in a ring array. Stirring blades are rotatably connected to the rotating interfaces. A mesh disc is snapped into the port of the stirring blade. A connecting shaft is connected to the end face of the mesh disc. A driven bevel gear is fitted at the other end of the connecting shaft. Multiple driven bevel gears mesh with the same driving bevel gear. The same fixed shaft is fitted inside the multiple driving bevel gears. A shaft hole is opened at the bottom of the stirring shaft. The fixed shaft is rotatably connected to the shaft hole. A bridging shaft is connected to the bottom end of the fixed shaft. The other end of the bridging shaft is connected to the bottom of the discharge pipe.

[0019] As a further description of the above technical solution:

[0020] A partition plate is fitted on the fixed shaft. The partition plate is located between two adjacent active bevel gears. A U-shaped tube connects two adjacent stirring blades. Multiple U-shaped tubes and multiple partition plates are combined to make the water flow in a single circulation along multiple stirring blades and stirring shaft.

[0021] A method of using a mixing apparatus for processing heavy oil viscosity reducers includes the following steps:

[0022] When producing heavy oil viscosity reducer, first add various raw materials into the inner tank according to the predetermined ratio, then start the motor. Its output shaft drives the stirring shaft to rotate at high speed in the inner tank. The stirring shaft then drives multiple stirring blades to rotate, starting the mixing process.

[0023] During mixing, the mixing shaft drives the mixing blades to make circular motion. The fixed shaft remains stationary while the mixing shaft rotates due to the support of the bridging shaft. The driven bevel gear and the driving bevel gear of the same height form a planetary gear set, which drives the mixing blades to rotate longitudinally through the adapter shaft and the mesh disk. This mixing method can mix raw materials in all directions and at multiple levels, and utilizes the high viscosity of the product to accelerate longitudinal flow and exchange, allowing the raw materials and products to rotate horizontally and move up and down at the same time, improving production efficiency and mixing effect.

[0024] At the same time, the water pump is turned on, which draws distilled water from the bottom of the stirring shaft through the suction pipe. After being sucked in through the second water inlet and the second adapter sleeve, it is injected into the spiral groove through the pressure relief pipe. The distilled water is heated by the heating system at the bottom of the reactor, and flows along the spiral groove through the return pipe to the top of the stirring shaft. Under the action of the partition plate, it flows through each layer of stirring blades in sequence, and finally flows back to the bottom of the stirring shaft, forming an integrated internal and external single-circulation water bath heating system.

[0025] This system ensures uniform temperature inside the tank, improves mixing quality, reduces product adhesion viscosity, and allows for more uniform stirring and more thorough reaction, thereby increasing the yield of heavy oil viscosity reducers.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, an integrated internal and external single-circulation water bath heating system was successfully constructed. With its unique design and circulation mechanism, this system can promote uniform and efficient heat transfer, resulting in a highly uniform temperature distribution inside the inner tank. This uniform temperature environment plays a key role in improving the mixing quality of the heavy oil viscosity reducer. By water bath heating the inner tank, stirring shaft, stirring blades, and U-shaped tube in all directions, the adhesion viscosity of the product on the equipment surface is effectively reduced, reducing the stirring resistance and uneven mixing problems caused by excessive viscosity. As a result, the product inside the inner tank can be fully stirred under more suitable conditions, the contact between the components is closer, the reaction is more complete, and the yield of the heavy oil viscosity reducer is significantly improved.

[0028] 2. In this invention, multiple stirring blades can effectively stir various raw materials when they are in circular motion. Since the product of the reaction of various raw materials has a high viscosity, the rotation of multiple stirring blades, along with the high viscosity generated, can accelerate the flow and exchange of the product in the longitudinal direction. This allows the raw materials and products to move up and down while rotating horizontally, which facilitates the thorough mixing of various raw materials for the heavy oil viscosity reducer. This greatly improves the production efficiency and mixing effect of the heavy oil viscosity reducer and has good practicality. Attached Figure Description

Detailed Implementation

[0041] 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.

[0042] Please see the appendix Figure 1 -Appendix Figure 10 This invention provides a technical solution: a mixing device for processing heavy oil viscosity reducers, comprising a frame 1, a control panel 3 installed on the top of the frame 1, a mixing mechanism 2 fitted inside the frame 1, the mixing mechanism 2 including a reaction vessel 201 fitted inside the frame 1, an inner liner 202 fitted inside the reaction vessel 201, a combination port 203 opened at the bottom of the reaction vessel 201, a discharge pipe 204 fitted inside the combination port 203, one end of the discharge pipe 204 being snapped to the bottom of the inner liner 202, a first valve 205 installed at the other end of the discharge pipe 204, a spiral groove 206 opened on the outer wall of the inner liner 202, a water inlet pipe 207 snapped to the bottom end of the outer wall of the reaction vessel 201 corresponding to the spiral groove 206, a second valve 208 installed at the other end of the water inlet pipe 207, and a reflux hole 19 opened on the top end of the outer wall of the reaction vessel 201 corresponding to the spiral groove 206;

[0043] The top of the reactor 201 is connected to the inner liner 202, and a stirring mechanism 4 is provided between the stirring mechanism 4 and the mixing mechanism 2.

[0044] Specifically, the stirring mechanism 4 includes a vessel cover 401 connected to the top of the reactor 201. The top of the vessel cover 401 has a first transfer hole, and a stirring shaft 403 is rotatably connected in the first transfer hole. The bottom of the discharge pipe 204 has a second transfer hole, and the other end of the stirring shaft 403 is rotatably connected in the second transfer hole. A motor 402 is installed on the top of the vessel cover 401. The output shaft of the motor 402 is connected to the top of the stirring shaft 403. The top of the stirring shaft 403 has a plurality of first water inlets 404 arranged in a ring array, and the bottom of the stirring shaft 403 has a plurality of second water inlets 405 arranged in a ring array.

[0045] The specific implementation method is as follows: During the process of stirring multiple raw materials by driving multiple stirring blades 10 in a circular motion, the bottom end of the fixed shaft 15 is fixedly supported by the bridging shaft 16. Therefore, during the rapid rotation of the stirring shaft 403, the fixed shaft 15 is in a relatively stationary state. Multiple driven bevel gears 13 located at the same layer height are combined with the meshing driving bevel gear 18 to form a planetary gear set. Under the transmission action of the planetary gear set, multiple driven bevel gears 13 drive multiple stirring blades 10 to rotate in the longitudinal direction through multiple sets of adapter shafts 12 and mesh disks 11. When the multiple stirring blades 10 are in a circular motion, they can play a good stirring role for multiple raw materials. Since the product after the reaction of multiple raw materials has a high viscosity, the rotation behavior of multiple stirring blades 10, and the high viscosity generated, can accelerate the flow and exchange of the product in the longitudinal direction.

[0046] Specifically, the water bath heating mechanism 6 includes two second sealed bearings 601 fitted onto the bottom end of the stirring shaft 403. The two second sealed bearings 601 are located on both sides of the second water inlet 405. The outer walls of the two second sealed bearings 601 are fitted with the same second adapter sleeve 602. The outer wall of the second adapter sleeve 602 is clamped with a suction pipe 603. A water pump 604 is provided inside the frame 1. The other end of the suction pipe 603 is connected to the inlet of the water pump 604. The outlet of the water pump 604 is connected to a pressure relief pipe 605. The other end of the pressure relief pipe 605 is connected to the other end of the water inlet pipe 207. First sealed bearings 5 ​​are fitted onto both sides of the stirring shaft 403 corresponding to the first water inlet 404. The same first adapter sleeve 7 is fitted onto the two first sealed bearings 5. A return pipe 8 is clamped onto the first adapter sleeve 7. The other end of the return pipe 8 is clamped into the return hole 19. Multiple sets of ring arrays are provided on the stirring shaft 403. Multiple adapters 9 are connected to the series of agitators, and stirring blades 10 are rotatably connected to the adapters 9. A mesh plate 11 is snapped into the port of the stirring blade 10. An adapter shaft 12 is connected to the end face of the mesh plate 11. A driven bevel gear 13 is fitted to the other end of the adapter shaft 12. Multiple driven bevel gears 13 mesh with the same driving bevel gear 18. The same fixed shaft 15 is fitted inside the multiple driving bevel gears 18. A shaft hole is opened at the bottom of the stirring shaft 403. The fixed shaft 15 is rotatably connected to the shaft hole. A bridging shaft 16 is connected to the bottom end of the fixed shaft 15. The other end of the bridging shaft 16 is connected to the bottom of the discharge pipe 204. A partition plate 17 is fitted on the fixed shaft 15. The partition plate 17 is located between two adjacent driving bevel gears 18. A U-shaped pipe 14 is connected between two adjacent stirring blades 10. Multiple U-shaped pipes 14 and multiple partition plates 17 are combined to make the water flow in a single circulation along the multiple stirring blades 10 and the stirring shaft 403.

[0047] The specific implementation method is as follows: The water pump 604 is controlled to operate. During operation, the water pump 604 draws distilled water from the bottom of the stirring shaft 403 through its inlet via a suction pipe 603. Under suction, this distilled water flows through multiple second inlet holes 405 into the second adapter sleeve 602 and is then drawn into the water pump 604 by the suction pipe 603. The distilled water is then injected into the spiral groove 206 through its outlet via a pressure relief pipe 605. After flowing into the lowest point of the spiral groove 206, the distilled water is heated by a heating system installed at the bottom of the reaction vessel 201. The heated distilled water flows along the spiral groove 206 to the return pipe 8, and then through the return pipe 8 to the top of the stirring shaft 403. With the partition plate 17 at the highest point blocking the flow, the distilled water located at the top of the stirring shaft 403 flows into the stirring blades 10 at the highest point, and then flows through the U-shaped pipes 14 to the stirring blades 10 at the next higher level. Since there is no partition plate 17 between the next higher level and the adjacent next lower level, and there is a partition plate 17 between the next lower level and the next lower level, the distilled water flows into the stirring blades 10 at the next lower level, and then flows through the U-shaped pipes 14 to the stirring blades 10 at the bottom level, and finally flows to the bottom of the stirring shaft 403, thus forming an integrated single-circulation water bath heating system, which makes the internal temperature distribution of the inner tank 202 more uniform.

[0048] A method of using a mixing apparatus for processing heavy oil viscosity reducers includes the following steps:

[0049] When producing heavy oil viscosity reducer, first add various raw materials into the inner tank 202 according to the predetermined ratio, then start the motor 402, whose output shaft drives the stirring shaft 403 to rotate at high speed in the inner tank 202, and the stirring shaft 403 drives multiple stirring blades 10 to rotate, thus starting the mixing process.

[0050] During mixing, the mixing shaft 403 drives the mixing blades 10 to make circular motion. The fixed shaft 15 remains stationary when the mixing shaft 403 rotates due to the support of the bridging shaft 16. The driven bevel gear 13 and the driving bevel gear 18 of the same height form a planetary gear set, which drives the mixing blades 10 to rotate longitudinally through the adapter shaft 12 and the mesh disk 11. This mixing method can mix raw materials in all directions and at multiple levels, and utilizes the high viscosity of the product to accelerate longitudinal flow and exchange, allowing the raw materials and products to rotate horizontally and move up and down at the same time, thereby improving production efficiency and mixing effect.

[0051] At the same time, the water pump 604 is turned on, which draws distilled water from the bottom of the stirring shaft 403 through the suction pipe 603. After being sucked in through the second water inlet 405 and the second adapter sleeve 602, it is injected into the spiral groove 206 through the pressure relief pipe 605. The distilled water is heated by the heating system at the bottom of the reaction vessel 201, and flows along the spiral groove 206 through the return pipe 8 to the top of the stirring shaft 403. Under the action of the partition plate 17, it flows through each layer of stirring blades 10 in sequence, and finally flows back to the bottom of the stirring shaft 403, forming an integrated single-circulation water bath heating system.

[0052] This system ensures uniform temperature in the inner tank 202, improves mixing quality, reduces product adhesion viscosity, and allows for more uniform stirring and more thorough reaction, thereby increasing the yield of heavy oil viscosity reducers.

[0053] Working principle and usage:

[0054] First, according to the predetermined ratio, all kinds of raw materials required for the production of heavy oil viscosity reducer are added into the inner tank 202. Then, the motor 402 is started, its output shaft starts to run, and drives the stirring shaft 403 to rotate at high speed inside the inner tank 202. The stirring shaft 403 drives multiple stirring blades 10 to rotate synchronously, and fully stirs the various raw materials, thereby starting the mixing and processing stage of heavy oil viscosity reducer.

[0055] During the stirring process, the stirring shaft 403 drives the stirring blades 10 to make a circular motion. At this time, the fixed shaft 15 remains relatively stationary when the stirring shaft 403 rotates rapidly because its bottom end is stably supported by the bridging shaft 16. Multiple driven bevel gears 13 of the same height and the meshing driving bevel gear 18 together form a planetary gear set. Under the transmission action of this gear set, multiple driven bevel gears 13 drive multiple stirring blades 10 to rotate in the longitudinal direction through multiple sets of adapter shafts 12 and mesh disks 11. This unique stirring method enables the stirring blades 10 to stir multiple raw materials in an all-round and multi-layer manner when making a circular motion. Given that the product after the raw material reaction has a high viscosity, the rotation of the stirring blades 10 can accelerate the flow and exchange of the product in the longitudinal direction with the help of this high viscosity, so that the raw materials and products can move up and down while rotating horizontally, thereby ensuring that the multiple raw materials of the heavy oil viscosity reducer are fully mixed, significantly improving production efficiency and mixing effect, and showing good practicality.

[0056] Simultaneously, water pump 604 is turned on. When water pump 604 is working, its inlet draws distilled water from the bottom of the stirring shaft 403 through the suction pipe 603. Under suction, the distilled water flows into the second adapter sleeve 602 through multiple second water inlets 405, and is then drawn into the water pump 604 by the suction pipe 603. Subsequently, it is injected into the spiral groove 206 through the pressure relief pipe 605 from the outlet. After the distilled water flows into the lowest point of the spiral groove 206, the heating system installed at the bottom of the reactor 201 heats it. The heated distilled water flows along the spiral groove 206 to the return pipe 8, and then... The water flows through the return pipe 8 to the top of the stirring shaft 403. Under the obstruction of the partition plate 17 at the highest point, the distilled water at the top of the stirring shaft 403 flows into the multiple stirring blades 10 at the highest point. Then, it flows through multiple U-shaped pipes 14 to the multiple stirring blades 10 at the second-highest level. Since there is no partition plate 17 between the second-highest level and the next level, but there is a partition plate 17 between the next level and the level below it, the distilled water can flow into the multiple stirring blades 10 at the next level and the bottom level in sequence, and finally flow back to the bottom of the stirring shaft 403, forming a complete internal and external integrated single-circulation water bath heating system.

[0057] This system makes the internal temperature distribution of the inner tank 202 more uniform, effectively improving the mixing quality of the heavy oil viscosity reducer. By water bath heating the inner tank 202, stirring shaft 403, stirring blade 10 and U-shaped tube 14, the adhesion viscosity of the product is reduced, the product inside the inner tank 202 is stirred more uniformly, the chemical reaction is carried out more thoroughly, and thus the yield of the heavy oil viscosity reducer is increased.

[0058] The above are merely preferred embodiments 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.
