Description

Technical Field

[0001] This utility model relates to the field of purification reaction vessels, specifically an aromatic hydrocarbon purification reaction vessel. Background Technology

[0002] Aromatic hydrocarbon extraction is a process that uses a solvent to separate aromatic components from other components in petroleum. The extracted solvent is distilled to recover it. The recovered solvent is regenerated for reuse. The regenerated solvent is stored for later use. The extracted aromatic hydrocarbons are then separated from other components. Further purification of the aromatic hydrocarbon product is achieved through methods such as distillation.

[0003] When it is necessary to clean and repair the inside of the reactor, the lid usually needs to be removed. Since traditional distillation reactors are usually one-piece structures, it is inconvenient to open the reactor lid, and disassembly and assembly are time-consuming and laborious.

[0004] Therefore, an aromatic hydrocarbon purification reactor is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an aromatic hydrocarbon purification reactor.

[0008] Preferably, a scraper is fixedly connected to the side of the heat-conducting plate, the side of the scraper is in contact with the inner wall of the reactor, and a spiral blade is fixedly connected to the surface of the heat-conducting plate; this step can increase the stirring efficiency of the stirring rod on the raw materials through the spiral blade, and can scrape the inner wall of the reactor through the scraper to reduce the raw materials accumulated on the inner wall of the reactor.

[0009] Preferably, a sealing groove is provided on the top of the reactor, and a sealing ring is fixedly connected to the bottom of the top cover. The sealing groove and the sealing ring are slidably connected. This step can increase the sealing performance when the top cover is connected to the reactor when the sealing ring is connected to the sealing groove.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, an aromatic hydrocarbon purification reactor includes a base 1; a reactor 12 is fixedly connected inside the base 1, a top cover 13 is slidably connected to the top of the reactor 12, an electric actuator 14 is fixedly connected to the side of the base 1, the top of the electric actuator 14 is fixedly connected to the top cover 13, a motor 15 is fixedly connected to the top of the top cover 13, a cross-shaped limiting block 16 is fixedly connected to the output end of the motor 15, a heat-conducting plate 17 is fixedly connected to the inner side of the base 1, and a mounting ring 18 is fixedly connected to the inner side of the heat-conducting plate 17. The mounting ring 18 rotates internally. A stirring rod 19 is dynamically connected, and a cross-shaped limiting groove 110 is opened on the top of the stirring rod 19. The cross-shaped limiting block 16 is slidably connected to the cross-shaped limiting groove 110. During operation, the motor 15 drives the cross-shaped limiting block 16 to rotate, which in turn drives the stirring rod 19 to rotate. The rotation of the stirring rod 19 stirs the raw materials inside the reactor 12. When it is necessary to separate the top cover 13 from the reactor 12 for cleaning, the electric push rod 14 drives the top cover 13 to move. 4. Move the motor 15 and the cross-shaped limiting block 16 to separate them from the cross-shaped limiting groove 110 on the top of the stirring rod 19. When the top cover 13 moves to a certain height, the stirring rod 19 can be removed from the reactor 12, separating the bottom of the stirring rod 19 from the mounting ring 18. When it is necessary to connect the top cover 13 to the reactor 12, first insert the bottom of the stirring rod 19 into the interior of the mounting ring 18, then adjust the angle of the stirring rod 19 so that the cross-shaped limiting groove 110 on its top aligns with the cross-shaped limiting block 16, and then the electric actuator 14 drives the stirring rod 19 to move. The top cover 13 moves down, causing the cross-shaped limiting block 16 to insert into the cross-shaped limiting groove 110. At this time, the motor 15 can drive the cross-shaped limiting groove 110 to rotate through the cross-shaped limiting block 16. This step can separate the top cover 13 from the reactor 12 by moving the top cover 13 up and down, which is convenient for the internal maintenance of the reactor 12. At the same time, it can be separated from the stirring rod 19 and the stirring rod 19 can be taken out of the internal part of the reactor 12. The stirring rod 19 can also be disassembled and replaced, which is convenient for cleaning and inspection of the internal part of the reactor 12.

[0024] like Figures 1 to 3As shown, a heating plate 21 is fixedly connected to the surface of the reactor 12, and a heating groove 22 is opened on the surface of the reactor 12. The heating groove 22 is connected to the heat-conducting plate 17, and a heating pipe 23 is connected to the side of the heat-conducting plate 17. During operation, hot water or hot air is sent to the interior of the heating plate 21 through the connecting pipe on the surface of the heating plate 21, so that it comes into contact with the heating groove 22, enters the interior of the heat-conducting plate 17 through the reactor 12, and then enters the interior of the heating pipe 23 to heat the interior and inner wall of the reactor 12. This step can heat the inner wall of the reactor 12 through the heating plate 21. The heating groove 22 can shorten the thickness of the inner wall of the reactor 12 and increase the heating speed of the interior of the reactor 12. Hot water can enter the interior of the heat-conducting plate 17 and the heating pipe 23 to heat the raw materials from the interior of the reactor 12, thereby increasing the efficiency of heating the raw materials.

[0025] like Figure 2 and Figure 4 As shown, a scraper 31 is fixedly connected to the side of the heat-conducting plate 17. The side of the scraper 31 is in contact with the inner wall of the reactor 12. A spiral blade 32 is fixedly connected to the surface of the heat-conducting plate 17. During operation, when the stirring rod 19 rotates, it drives the scraper 31 and the spiral blade 32 to rotate. The scraper 31 scrapes the inner wall of the reactor 12, and the spiral blade 32 drives the movement of the raw materials inside. This step can increase the stirring efficiency of the stirring rod 19 on the raw materials through the spiral blade 32, and the scraper 31 can scrape the inner wall of the reactor 12 to reduce the raw materials accumulated on the inner wall of the reactor 12.

[0026] like Figure 3 and Figure 4 As shown, a sealing groove 41 is provided on the top of the reactor 12, and a sealing ring 42 is fixedly connected to the bottom of the top cover 13. The sealing groove 41 and the sealing ring 42 are slidably connected. During operation, when the top cover 13 moves, it drives the sealing ring 42 to move, causing it to separate from the sealing groove 41. This step, when the sealing ring 42 is connected to the sealing groove 41, can increase the sealing performance when the top cover 13 is connected to the reactor 12.

[0027] like Figure 1 As shown, the top of the top cover 13 is connected to a filter plate 51, and the top of the filter plate 51 is connected to an exhaust valve. During operation, the waste gas generated inside the reactor 12 can be discharged through the filter plate 51 and the exhaust valve. The waste gas is filtered by the filter plate 51. In this step, the exhaust valve can discharge the waste gas inside the reactor 12, and the filter plate 51 can filter the waste gas, reducing the pollution of the waste gas.

[0028] like Figure 2 and Figure 4As shown, a limiting ring 61 is fixedly connected to the bottom of the top cover 13, and the limiting ring 61 is slidably connected to the stirring rod 19. During operation, when the top cover 13 moves, it drives the limiting ring 61 to move, so that the limiting ring 61 is connected to the stirring rod 19. This step can increase the stability of the top of the stirring rod 19 when it rotates when the stirring rod 19 is connected to the limiting ring 61.

[0029] Working principle: The motor 15 drives the cross-shaped limiting block 16 to rotate, which in turn drives the stirring rod 19 to rotate. The rotation of the stirring rod 19 drives the scraper 31 and the spiral blade 32 to rotate. The scraper 31 scrapes the inner wall of the reactor 12, while the spiral blade 32 moves the internal raw materials, thus stirring. When it is necessary to separate the top cover 13 from the reactor 12 for cleaning, the electric push rod 14 moves the top cover 13, which in turn moves the sealing ring 42 and the limiting ring 61, separating the sealing ring 42 from the sealing groove 41 and the limiting ring 61 from the stirring rod 19. The electric push rod 14 then drives the motor 15 and the cross-shaped limiting block 16 to move, separating them from the cross-shaped limiting groove 110 at the top of the stirring rod 19, thus opening the top cover 13. When a certain height is reached, the stirring rod 19 can be removed from the reactor 12, separating the bottom of the stirring rod 19 from the mounting ring 18. When it is necessary to connect the top cover 13 to the reactor 12, first insert the bottom of the stirring rod 19 into the interior of the mounting ring 18, and then adjust the angle of the stirring rod 19 so that the cross-shaped limiting groove 110 at its top aligns with the cross-shaped limiting block 16. Then, the electric push rod 14 drives the top cover 13 to move down, causing the cross-shaped limiting block 16 to be inserted into the interior of the cross-shaped limiting groove 110. At this time, the motor 15 can drive the cross-shaped limiting groove 110 to rotate through the cross-shaped limiting block 16, sending hot water or hot air through the connecting pipe on the surface of the heating plate 21 into the interior of the heating plate 21, so that it contacts the heating tank 22, enters the interior of the heat-conducting plate 17 through the reactor 12, and then enters the interior of the heating tube 23 to heat the interior and inner wall of the reactor 12.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
