Description

Technical Field

[0001] This invention relates to the field of reaction vessels, and more particularly to a reaction vessel. Background Technology

[0002] Coal tar processing typically produces about 50% to 60% bitumen, a major product of coal tar processing. The larger the processing scale, the greater the bitumen production. Bitumen is a complex, dark brown mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives; it is a type of high-viscosity organic liquid.

[0003] In the production process of asphalt, a reaction vessel is needed to heat and react it. Due to the high viscosity of asphalt, the stirring motor experiences significant resistance during operation, and only a portion of the asphalt flows with the stirring motor, making it difficult to fully mix the asphalt and resulting in insufficient asphalt processing efficiency. Summary of the Invention

[0004] To improve the mixing effect of the reaction vessel, the present invention provides a reaction vessel.

[0005] The reaction vessel provided by this invention adopts the following technical solution:

[0006] A reaction vessel includes a shell, an internal stirring shaft with stirring blades, and a stirring assembly for tumbling asphalt between the stirring shaft and the shell.

[0007] By adopting the above technical solution, during the rotation of the mixing shaft, the mixing blades agitate the asphalt inside the shell. At the same time, the mixing component flips the asphalt away from the mixing shaft area to the area near the mixing shaft, thereby enabling the asphalt inside the shell to flow and be fully mixed, improving the mixing efficiency and mixing effect of the asphalt.

[0008] Optionally, the stirring assembly includes a rotating drum disposed inside the housing and coaxial with the stirring shaft. A connecting assembly is provided between the rotating drum and the stirring shaft. The rotating drum has multiple evenly distributed through holes. A driving blade is provided on the side of the rotating drum away from the stirring shaft. The stirring blade and the driving blade rotate in opposite directions.

[0009] By adopting the above technical solution, when the mixing shaft rotates, the asphalt near the mixing shaft moves along the axis of the mixing shaft and diffuses outwards from the bottom of the shell. The asphalt diffused from the bottom of the shell flows into the gap between the rotating drum and the shell. At the same time, under the action of the connecting component, the rotating drum and the mixing shaft rotate in the same direction. The driving blades on the rotating drum cause the asphalt between the rotating drum and the shell to flow upwards. Meanwhile, the asphalt between the shell and the rotating drum reaches the space between the rotating drum and the mixing shaft again through the through hole. This allows the asphalt inside the shell to flow quickly, thereby achieving full mixing of the asphalt.

[0010] Optionally, the connecting assembly includes a connecting cylinder coaxial with the rotating drum, the connecting cylinder abutting against the inner wall of the rotating drum, a slider slidably connected to the rotating drum along the axis of the rotating drum, a connecting hole corresponding to the through hole on the connecting cylinder, a connecting rod connecting the connecting cylinder and the stirring shaft, and a vibrating element between the rotating drum and the stirring shaft.

[0011] By adopting the above technical solution, when the mixing shaft rotates, the mixing shaft drives the connecting cylinder to rotate through the connecting rod. At the same time, the connecting cylinder drives the rotating drum to rotate. During the rotation, the vibrating component drives the rotating drum to vibrate. Thus, the rotating drum slides relative to the connecting cylinder through the slider. By vibrating the rotating drum, the asphalt around the rotating drum can be better stirred, reducing the possibility of asphalt adhesion and blockage.

[0012] Optionally, the vibrating element includes a vibrating rod, one end of which is connected to the rotating drum, and the other end is provided with a vibrating block. A support rod coaxial with the rotating drum is slidably and rotatably connected to the vibrating block. The support rod is fixedly connected to the housing. An annular groove is provided on the vibrating block. Multiple evenly distributed protrusions are provided on one side of the annular groove, and multiple evenly distributed protrusions are also provided on the other side. The protrusions on both sides of the annular groove are staggered. A driving block is provided above the support rod, which is inserted into the annular groove and abuts against the protrusions.

[0013] By adopting the above technical solution, during the rotation of the drum with the stirring shaft, the vibrating block is driven to rotate by the vibrating rod. The vibrating block rotates relative to the support rod, and the driving block on the support rod slides in the annular groove. During the rotation of the vibrating block, the driving block squeezes the protrusion, causing the vibrating block to slide up and down along the support rod, thereby driving the drum to vibrate up and down.

[0014] Optionally, the vibrating block is provided with a unclogging component at one end facing the bottom of the housing. The unclogging component includes a unclogging rod disposed on the vibrating block. A unclogging ring is provided at the discharge port of the housing. A fixing rod is provided between the unclogging ring and the discharge port. Multiple evenly distributed levers are hinged on the unclogging ring. The unclogging rod is rotatably connected to the unclogging ring, and a lever block is provided on the unclogging rod to abut against one of the levers. A spring is provided between the lever and the unclogging ring.

[0015] By adopting the above technical solution, when the vibrating block rotates, the vibrating block drives the unblocking rod to rotate, and the unblocking rod drives the dial block to rotate inside the unblocking ring. The dial block drives the dial rod to rotate relative to the unblocking ring by squeezing, so that the dial rod can agitate the asphalt in the outlet, thereby improving the discharge efficiency of the outlet and reducing the possibility of blockage.

[0016] Optionally, the outer side of the housing is provided with a jacket, the jacket is provided with a coil, and the jacket is also provided with a plurality of waterwheels distributed along the rotation direction of the drive blades and rotatably connected to the outer side of the housing. A rotating rod inserted into the housing is fixedly connected at the axis of the waterwheel, and a clearing blade is provided at one end of the rotating rod located inside the housing. The waterwheel is located inside the coil.

[0017] By adopting the above technical solution, when the heating medium flows inside the coil, the heating medium drives the waterwheel to rotate, the waterwheel drives the rotating rod to rotate, and the rotating rod further drives the asphalt flow between the shell and the rotating drum through the clearing blades, thereby improving the asphalt flow speed and mixing efficiency.

[0018] Optionally, the rotating drum has an arc-shaped hole surrounding the outside of the through hole, and a scraper is slidably connected to the connecting drum. One end of the scraper passes through the arc-shaped hole and abuts against the inner wall of the through hole. The connecting drum has the same arc-shaped hole surrounding the outside of the connecting hole, and a scraper that passes through the arc-shaped hole and abuts against the inner wall of the connecting hole is also slidably connected to the rotating drum.

[0019] By adopting the above technical solution, the relative movement of the rotating drum and the connecting drum causes the scraper to move along the arc-shaped hole, thereby scraping the inner wall of the through hole or connecting hole, reducing the possibility of asphalt adhering and clogging the through hole or connecting hole, and thus improving the flow efficiency of asphalt.

[0020] Optionally, the upper end of the rotating drum is set to be arc-shaped and bent downward toward the side where the stirring shaft is located.

[0021] By adopting the above technical solution, the downward-sloping arc shape at the upper end of the rotating drum can guide the asphalt and protect the connecting cylinder.

[0022] In summary, the present invention has at least one of the following beneficial technical effects:

[0023] The mixing unit flips the asphalt away from the mixing shaft to the area near the mixing shaft, thereby allowing the asphalt inside the shell to flow and be fully mixed, improving the mixing efficiency and effect of the asphalt.

[0024] When the mixing shaft rotates, the mixing shaft drives the connecting cylinder to rotate through the connecting rod. At the same time, the connecting cylinder drives the rotating drum to rotate. During the rotation, the vibrating component drives the rotating drum to vibrate. As a result, the rotating drum slides relative to the connecting cylinder through the slider. By vibrating the rotating drum, the asphalt around the rotating drum can be better agitated, reducing the possibility of asphalt adhesion and blockage.

[0025] When the vibrating block rotates, it drives the unblocking rod to rotate, which in turn drives the dial block to rotate within the unblocking ring. The dial block, through compression, drives the dial rod to rotate relative to the unblocking ring, thereby agitating the asphalt in the outlet and improving the discharge efficiency of the outlet, thus reducing the possibility of blockage.

[0031] The following is in conjunction with the appendix Figures 1-4 The present invention will be described in further detail below.

[0032] This invention discloses a reaction vessel. (Refer to...) Figure 1 A reaction vessel includes a shell 1, an end cap 11 on the upper end of the shell 1, a feed inlet 12 at the upper end of the shell 1, and a discharge outlet 13 at the bottom of the shell 1.

[0033] A protective cover 14 is provided above the end cap 11 of the housing 1. A drive motor is installed inside the protective cover 14. A stirring shaft 2 is rotatably connected at the center of the end cap 11. One end of the stirring shaft 2 is located inside the protective cover 14, and the other end is located inside the housing 1. A stirring blade 21 is fixed on the outer wall of the end of the stirring shaft 2 located inside the housing 1. The drive motor is connected to the stirring shaft 2 through a bevel gear. At the same time, a stirring assembly 3 is also provided between the stirring shaft 2 and the housing 1.

[0034] Asphalt enters the shell 1 through the feed inlet 12, and then the drive motor drives the stirring shaft 2 to rotate. The stirring blades 21 agitate the asphalt inside the shell 1. At the same time, the stirring assembly 3 flips the asphalt away from the stirring shaft 2 to the area near the stirring shaft 2, thereby allowing the asphalt inside the shell 1 to flow and be fully stirred.

[0035] The mixing assembly 3 includes a rotating drum 31 disposed inside the housing 1 and coaxial with the mixing shaft 2. A connecting assembly 4 is provided between the rotating drum 31 and the mixing shaft 2. The rotating drum 31 has a plurality of evenly distributed through holes 311. A driving blade 32 is provided on the side of the rotating drum 31 away from the mixing shaft 2. The mixing blade 21 and the driving blade 32 rotate in opposite directions. The mixing blade 21 drives the asphalt to move toward the discharge port 13, and the driving blade 32 drives the asphalt to move away from the discharge port 13.

[0036] Reference Figure 1 and Figure 2 The connecting assembly 4 includes a connecting cylinder 41 coaxial with the rotating cylinder 31. The outer wall of the connecting cylinder 41 abuts against the inner wall of the rotating cylinder 31. A slider 42 is fixedly connected to the connecting cylinder 41. The slider 42 is slidably connected to the inner wall of the rotating cylinder 31 along the axis of the rotating cylinder 31. A connecting hole 411 corresponding to the through hole 311 is provided on the connecting cylinder 41. A plurality of connecting rods 43 distributed around the axis of the connecting cylinder 41 are provided between the connecting cylinder 41 and the stirring shaft 2. One end of the connecting rod 43 is fixed on the connecting cylinder 41 and the other end is fixed on the stirring shaft 2. A vibrating element 44 is provided between the rotating cylinder 31 and the stirring shaft 2.

[0037] When the stirring shaft 2 rotates, the asphalt near the stirring shaft 2 moves along the axial direction of the stirring shaft 2 and diffuses outwards from the bottom of the housing 1. The asphalt diffused from the bottom of the housing 1 flows into the gap between the rotating drum 31 and the housing 1. The stirring shaft 2 drives the connecting drum 41 to rotate via the connecting rod 43, and at the same time, the connecting drum 41 drives the rotating drum 31 to rotate. The rotating drum 31 and the stirring shaft 2 rotate in the same direction. The driving blades 32 on the rotating drum 31 cause the asphalt between the rotating drum 31 and the housing 1 to flow upwards. At the same time, the asphalt between the housing 1 and the rotating drum 31 returns to the space between the rotating drum 31 and the stirring shaft 2 through the through hole 311 and the connecting hole 411, thereby enabling the asphalt inside the housing 1 to flow quickly and be fully mixed. When the stirring shaft 2 rotates, the vibrator 44 drives the rotating drum 31 to vibrate, thereby causing the rotating drum 31 to slide relative to the connecting drum 41 via the slider 42. By vibrating the rotating drum 31, the possibility of asphalt adhesion is reduced.

[0038] Reference Figure 1 and Figure 3 The rotating cylinder 31 has an arc-shaped hole 312 surrounding the outside of the through hole 311. A scraper 412 is slidably connected to the connecting cylinder 41. One end of the scraper 412 passes through the arc-shaped hole 312 and abuts against the inner wall of the through hole 311. The connecting cylinder 41 has the same arc-shaped hole 312 surrounding the outside of the connecting hole 411. The rotating cylinder 31 also has a scraper 412 that passes through the arc-shaped hole 312 and abuts against the inner wall of the connecting hole 411.

[0039] The relative movement of the rotating drum 31 and the connecting drum 41 causes the scraper 412 to move along the arc-shaped hole 312, thereby scraping the inner wall of the through hole 311 or the connecting hole 411 by the scraper 412, reducing the possibility of asphalt adhering and clogging the through hole 311 or the connecting hole 411, and thus improving the flow efficiency of asphalt.

[0040] The vibrating element 44 includes a plurality of vibrating rods 441 evenly distributed around the axis of the rotating drum 31. One end of the vibrating rod 441 is fixedly connected to the rotating drum 31, and the other end is fixed with a vibrating block 442. The vibrating block 442 is inserted with a support rod 443. The support rod 443 passes through the stirring shaft 2 along the axis of the stirring shaft 2 and is fixedly connected to the protective cover 14. The vibrating block 442 is provided with an annular groove 444. A plurality of evenly distributed protrusions 445 are provided on one side of the annular groove 444, and a plurality of evenly distributed protrusions 445 are also provided on the other side. The protrusions 445 on both sides of the annular groove 444 are staggered. A driving block 446 is fixed on the support rod 443. The driving block 446 is inserted into the annular groove 444 and simultaneously abuts against the protrusions 445 on both sides of the annular groove 444.

[0041] During the rotation of the rotating drum 31 with the stirring shaft 2, the vibrating block 442 is driven to rotate by the vibrating rod 441. The vibrating block 442 rotates relative to the support rod 443. The driving block 446 on the support rod 443 slides in the annular groove 444. During the rotation of the vibrating block 442, the driving block 446 presses the protrusion 445, causing the vibrating block 442 to slide up and down along the support rod 443, thereby driving the rotating drum 31 to vibrate up and down.

[0042] A unclogging component 5 is provided at one end of the vibrating block 442 facing the bottom of the housing 1. The unclogging component 5 includes a unclogging rod 51 fixed on the vibrating block 442. The unclogging rod 51 is coaxially arranged with the stirring shaft 2. A unclogging ring 52 is sleeved at the end of the unclogging rod 51 away from the vibrating block 442. A fixing rod 53 is fixedly connected to the periphery of the unclogging ring 52. The end of the fixing rod 53 away from the unclogging ring 52 is fixed at the discharge port 13 of the housing 1. Multiple levers 54 are hinged on the unclogging ring 52 and evenly distributed around the unclogging rod 51. The unclogging rod 51 is rotatably connected to the unclogging ring 52. A lever block 55 is fixed on the unclogging rod 51. The lever block 55 abuts against one of the levers 54. A spring 56 is fixedly connected to the side of the lever 54 away from the unclogging rod 51. The spring 56 is also fixedly connected to the unclogging ring 52.

[0043] When the vibrating block 442 rotates, it drives the unblocking rod 51 to rotate. The unblocking rod 51 drives the agitator 55 to rotate within the unblocking ring 52. The agitator 55 drives the agitator 54 to rotate relative to the unblocking ring 52 by squeezing, thereby enabling the agitator 54 to agitate the asphalt in the outlet 13, thus improving the discharge efficiency of the outlet 13 and reducing the possibility of blockage.

[0044] Reference Figure 1 and Figure 4 A jacket 6 is fixed to the outside of the housing 1. A coil 61 is installed inside the jacket 6. Multiple waterwheels 62 are also provided inside the jacket 6, distributed along the rotation direction of the drive blades 32 and rotatably connected to the outside of the housing 1. A rotating rod 63 that penetrates into the housing 1 is fixedly connected to the axis of the waterwheel 62. A clearing blade 64 is provided at one end of the rotating rod 63 inside the housing 1. One side of the waterwheel 62 is located inside the coil 61.

[0045] When the heating medium flows inside the coil 61, the heating medium drives the waterwheel 62 to rotate, the waterwheel 62 drives the rotating rod 63 to rotate, and the rotating rod 63 further drives the asphalt flow between the shell 1 and the rotating drum 31 through the unblocking blade 64, thereby improving the asphalt flow speed and mixing efficiency.

[0046] The upper end of the rotating drum 31 can also be set to an arc shape and bend downward toward the side where the mixing shaft 2 is located. This is not shown in this embodiment. The downward-sloping arc shape of the upper end of the rotating drum 31 can provide guidance for the asphalt and at the same time provide protection for the connecting drum 41.

[0047] The implementation principle of a reaction vessel according to an embodiment of the present invention is as follows: After asphalt enters the shell 1 through the feed inlet 12, the drive motor drives the stirring shaft 2 to rotate. The stirring shaft 2, together with the rotating drum 31, drives the asphalt to circulate inside the shell 1, thereby quickly stirring the asphalt. After stirring is completed, the discharge port 13 of the shell 1 is opened, and the stirring shaft 2 drives the asphalt to flow out from the discharge port 13. The lever 54 moves the asphalt at the discharge port 13 to accelerate the discharge of asphalt, thereby improving the asphalt production efficiency.

[0048] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
