Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] During specific implementation: As Figures 1-7As shown in the figure, a negative pressure fractionation device for cutting slurry oil includes: a negative pressure fractionation barrel 1, a feed inlet 3 and a discharge outlet 4. A heating mechanism 2 is arranged on the side of the negative pressure fractionation barrel 1. The feed inlet 3 is arranged at the upper end of the negative pressure fractionation barrel 1, and the discharge outlet 4 is arranged at the lower end of the negative pressure fractionation barrel 1. A temperature monitoring mechanism 5 is arranged at the upper end inside the negative pressure fractionation barrel 1, and a stirring mechanism 6 is arranged at the lower end inside the negative pressure fractionation barrel 1. A collection mechanism 7 is arranged inside the negative pressure fractionation barrel 1. When the device is in use, first inject the slurry oil into the negative pressure fractionation barrel 1 through the feed inlet 3, and then start the heating mechanism 2 to heat the slurry oil. During the heating process, monitor it through the temperature monitoring mechanism 5. When the temperature reaches the requirement, introduce the slurry oil to the stirring mechanism 6. At this time, stir the slurry oil through the stirring mechanism 6, and continuously heat the slurry oil through the heating mechanism 2 during the stirring process. At this time, the lighter components evaporate and rise at a lower temperature, and are collected through the collection mechanism 7. The slurry oil after evaporation is taken out through the discharge outlet 4.

[0027] The heating mechanism 2 includes a first heat conducting plate 21, a first connecting block 22, a first bolt 23 and a first heater 24. Two first heat conducting plates 21 are symmetrically arranged on the side of the negative pressure fractionation barrel 1. First connecting blocks 22 are symmetrically arranged on the side of the first heat conducting plate 21. The first connecting block 22 is threadedly connected with a first bolt 23. A first heater 24 is arranged on the side of the first heat conducting plate 21. When the device is in use, start the first heater 24 to heat the first heat conducting plate 21, and transfer the heat to the side of the negative pressure fractionation barrel 1 through the first heat conducting plate 21 to heat the slurry oil inside the negative pressure fractionation barrel 1.

[0028] Two second heat conducting plates 25 are symmetrically arranged on the side of the negative pressure fractionation barrel 1. Second connecting blocks 26 are symmetrically arranged on the side of the second heat conducting plate 25. The second connecting block 26 is threadedly connected with a second bolt 27. A second heater 28 is arranged on the side of the second heat conducting plate 25. When the device is in use, start the second heater 28 to heat the second heat conducting plate 25, and transfer the heat to the side of the negative pressure fractionation barrel 1 through the second heat conducting plate 25 to heat the slurry oil inside the negative pressure fractionation barrel 1.

[0029] A material guiding plate 51 is arranged inside the negative pressure fractionation barrel 1, and an electric telescopic column 52 is arranged at the upper end inside the negative pressure fractionation barrel 1. The output shaft of the electric telescopic column 52 is connected with a soft rubber ball 53. When the device is in use, introduce the slurry oil to the upper end of the material guiding plate 51, and block the connecting pipe 72 through the soft rubber ball 53 connected to the output shaft of the electric telescopic column 52 to prevent the slurry oil from leaking out.

[0030] The temperature monitoring mechanism 5 includes a housing 54, a sliding rod 55, a third heat conducting plate 56, a soft rubber block 57, a spring column 58 and a switch 59. The upper end of the negative pressure fractionating barrel 1 is embedded with the housing 54. The upper end of the housing 54 is slidably connected with the sliding rod 55. The lower end of the housing 54 is connected with the third heat conducting plate 56. A soft rubber block 57 is arranged between the third heat conducting plate 56 and the sliding rod 55. Spring columns 58 are arranged equiangularly inside the housing 54, and switches 59 are arranged equiangularly inside the housing 54. When the device is in use, during the heating process, heat is transmitted to the soft rubber block 57 through the third heat conducting plate 56. At this time, the soft rubber block 57 expands due to heat. At this time, the soft rubber block 57 pushes the sliding rod 55 to slide inside the housing 54. When the switch 59 is triggered during the sliding process of the sliding rod 55, it indicates that the temperature has reached the required value at this time. At this time, the electric telescopic column 52 is triggered by the switch 59 to contract, so that the soft rubber ball 53 loses the blockage of the connecting pipe 72. At this time, the slurry falls to the side of the stirring mechanism 6.

[0031] The stirring mechanism 6 includes a driving motor 61, a first connecting rod 62, stirring plates 63 and ventilation holes 64. The lower end of the negative pressure fractionating barrel 1 is connected with the driving motor 61. The output shaft of the driving motor 61 is connected with the first connecting rod 62. The first connecting rod 62 is rotatably arranged inside the negative pressure fractionating barrel 1. Stirring plates 63 are arranged equiangularly on the side of the first connecting rod 62. Ventilation holes 64 are arranged equiangularly on the side of the stirring plates 63. When the device is in use, when the slurry reaches the inner bottom end of the negative pressure fractionating barrel 1, the driving motor 61 is started at this time. The first connecting rod 62 is driven by the driving motor 61 to rotate. During the rotation of the first connecting rod 62, the stirring plates 63 are driven to stir the slurry, so that the slurry is heated faster. At the same time, the resistance is reduced through the ventilation holes 64, and the bubbles are eliminated at the same time.

[0032] A baffle 71 is arranged inside the negative pressure fractionating barrel 1. The upper end of the baffle 71 is connected with the guide plate 51 through a connecting pipe 72. Air outlet holes 73 are arranged equiangularly at the upper end of the baffle 71.

[0033] Water guide holes 74 are arranged equiangularly on the side of the negative pressure fractionating barrel 1. A second connecting rod 75 is arranged inside the water guide holes 74. The second connecting rod 75 is rotatably connected with a rotating plate 76.

[0034] The collection mechanism 7 includes a water storage frame 77 and a water outlet 78. The side of the negative pressure fractionating barrel 1 is connected with the water storage frame 77. The lower end of the water storage frame 77 is provided with the water outlet 78. When the device is in use, during the heating process, the lighter components evaporate and rise at a lower temperature, and reach the upper surface of the baffle 71 through the air outlet holes 73. When the steam condenses into water droplets, at this time, the water droplets are guided to the water guide holes 74 through the conical surface at the upper end of the baffle 71. When there are more water droplets, the rotating plate 76 is pushed to rotate. At this time, the water droplets pass through the water guide holes 74 and fall into the water storage frame 77. At the same time, the water droplets can be discharged through the water outlet 78 during the use process.

[0035] When the utility model is in use, first, slurry is injected into the internal part of the negative pressure fractionation barrel 1 through the feed inlet 3. At this time, the slurry reaches the upper end of the material guiding plate 51, and the soft rubber ball 53 connected to the output shaft of the electric telescopic column 52 blocks the connecting pipe 72 to prevent the slurry from leaking. Subsequently, the first heater 24 is started to heat the first heat conducting plate 21, and the heat is transmitted to the side of the negative pressure fractionation barrel 1 through the first heat conducting plate 21 to heat the slurry inside the negative pressure fractionation barrel 1;

[0036] During the heating process, the heat is transmitted to the soft rubber block 57 through the third heat conducting plate 56. At this time, the soft rubber block 57 expands due to heat. At this time, the soft rubber block 57 pushes the sliding rod 55 to slide inside the housing 54. When the switch 59 is triggered during the sliding process of the sliding rod 55, it indicates that the temperature has reached the requirement at this time. At this time, the electric telescopic column 52 is triggered to contract through the switch 59, so that the soft rubber ball 53 loses the blockage of the connecting pipe 72, and at this time, the slurry falls to the side of the stirring mechanism 6;

[0037] When the slurry reaches the bottom end inside the negative pressure fractionation barrel 1, the driving motor 61 is started at this time. The driving motor 61 drives the first connecting rod 62 to rotate. During the rotation of the first connecting rod 62, the stirring plate 63 is driven to stir the slurry. At the same time, the second heater 28 is started to heat the second heat conducting plate 25, and the heat is transmitted to the side of the negative pressure fractionation barrel 1 through the second heat conducting plate 25 to heat the slurry inside the negative pressure fractionation barrel 1, so that the slurry is heated faster. At the same time, the resistance is reduced through the ventilation holes 64, and the bubbles are eliminated at the same time;

[0038] During the heating process, the lighter components evaporate and rise at a lower temperature, reach the upper surface of the baffle 71 through the air outlet hole 73. When the steam condenses into water droplets, at this time, the water droplets are guided to the water guiding hole 74 through the conical surface at the upper end of the baffle 71. When there are more water droplets, the rotating plate 76 is pushed to rotate. At this time, the water droplets pass through the water guiding hole 74 and fall into the water storage frame 77, and at the same time, the water droplets can be discharged through the water outlet 78 during the use process;

[0039] The evaporated slurry is taken out through the discharge port 4.

[0040] In addition, it should be understood that although this specification is described according to the embodiments, not each embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
