[0022] Embodiment

[0023] Please refer to Figures 1-4, the present utility model provides a technical solution: a vacuum fractionating tower for treating tire oil, including a vacuum fractionating tower for treating tire oil, which includes a vacuum reduction assembly 1. The vacuum reduction assembly 1 includes a tower body 11, a connecting pipe 12, a vacuum pump 13, a bracket 14, an electric pressure regulating valve 15, a pressure sensor 16, and a controller 17. One side of the upper surface of the tower body 11 is communicated with a connecting pipe 12. One end of the connecting pipe 12 far from the tower body 11 is communicated with a vacuum pump 13. One side top of the outer side wall of the tower body 11 near the connecting pipe 12 is welded with a bracket 14. The bottom of the vacuum pump 13 is fixedly connected to the top of the bracket 14. An electric pressure regulating valve 15 is installed on the upper part of the outer side wall of the tower body 11 near the bracket 14. A pressure sensor 16 is installed on the front part of the upper surface of the tower body 11. The front part of the outer side wall of the tower body 11 is fixedly connected with a controller 17. The output end of the pressure sensor 16 is electrically connected to the input end of the controller 17. The input ends of the vacuum pump 13 and the electric pressure regulating valve 15 are both electrically connected to the output end of the controller 17. Among them, the vacuum pump 13 mainly creates a relatively stable low-pressure environment by continuously pumping out the gas inside the tower body 11 to reduce the internal pressure, so as to achieve vacuum fractionation. Its function is to continuously discharge the gas inside the tower body 11, so that the internal pressure of the tower body 11 is continuously reduced. It usually pumps air at a relatively fixed rate. The electric pressure regulating valve 15 can finely adjust the internal pressure of the tower body 11. It can adjust the internal pressure of the tower body 11 at any time according to different stages of the fractionation process and actual needs, so that the fractionation process is always carried out under the most suitable pressure conditions. During the fractionation process, due to the influence of various factors, the internal pressure of the tower body 11 may fluctuate. The electric pressure regulating valve 15 can respond to these fluctuations in time, adjust the intake or exhaust volume by adjusting the opening of the valve, so as to maintain the dynamic balance of the internal pressure of the tower body 11. When an unexpected situation occurs, such as the pressure suddenly rises or falls beyond the safe range, the electric pressure regulating valve 15 can act quickly to prevent the internal pressure of the tower body 11 from being too high or too low and damaging the equipment and the fractionation process, playing a role in safety protection.

[0024] In this embodiment, specifically: a heating plate 18 is welded to the lower part of the inner side wall of the tower body 11. A coil heater 19 is fixedly connected to the bottom of the heating plate 18. A temperature sensor 20 is arranged at the center of the upper surface of the heating plate 18. The output end of the temperature sensor 20 is electrically connected to the input end of the controller 17. The input end of the coil heater 19 is electrically connected to the output end of the controller 17. By means of the temperature sensor 20, it is convenient to monitor the temperature inside the tower body 11 in real time. The heating plate 18 is uniformly heated by the coil heater 19, so as to heat the tire oil inside the tower body 11.

[0025] In this embodiment, specifically: a display screen 21 is provided on the upper part of the front surface of the controller 17, and a control panel 22 is provided on the lower part of the front surface of the controller 17 close to the display screen 21. The control panel 22 on the controller 17 facilitates the setting of parameters such as temperature and pressure required for fractional distillation, and the display screen 21 on the controller 17 facilitates the display of parameters such as pressure and temperature inside the tower body 11.

[0026] In this embodiment, specifically: an air outlet pipe 23 is connected to the center of the upper surface of the tower body 11, the air outlet end of the air outlet pipe 23 is connected to a condensation device 24, and a liquid collection pipe 25 is connected to the bottom of the side of the condensation device 24 away from the air outlet pipe 23. The gas is cooled by the condensation device 24, so that the gas is cooled into a liquid and flows out through the liquid collection pipe 25 for collection and subsequent processing.

[0027] In this embodiment, specifically: a support frame 26 is welded to the top of the outer side wall of the tower body 11 away from the connecting pipe 12, and the bottom of the condensation device 24 is fixedly connected to the top of the support frame 26. By supporting and fixing the condensation device 24 through the support frame 26, the stability of the condensation device 24 is increased.

[0028] In this embodiment, specifically: a feed pipe 27 is connected to the lower part of the outer side wall of the tower body 11 close to the support frame 26, and a plurality of discharge pipes 28 are connected to the lower part of the outer side wall of the tower body 11 away from the support frame 26 and close to the electric pressure regulating valve 15. The feed pipe 27 facilitates the input of tire oil into the tower body 11, and the discharge pipes 28 provided at different height positions of the tower body 11 facilitate the collection of products with different fractions.

[0029] In this embodiment, specifically: a plurality of trays 29 are provided inside the tower body 11. By means of the multi-layer trays 29 provided inside the tower body 11, the separation of different components is realized.

[0030] In this embodiment, specifically: a support ring 30 is fixedly connected to the bottom of the outer side wall of the tower body 11, and a plurality of support legs 31 are welded to the bottom of the support ring 30. By the support of the plurality of support legs 31 at the bottom of the support ring 30, the stability of the tower body 11 is increased.

[0031] Working principle or structural principle: When in use, turn on the power supply of the controller 17, and the display screen 21 and the control panel 22 light up. Set parameters such as the temperature and pressure required for fractional distillation through the control panel 22. Introduce the tire oil to be processed into the interior of the tower body 11 through the feed pipe 27. The controller 17 sends a start signal to the coil heater 19 according to the preset temperature parameter, and the coil heater 19 starts to work, heating the heating plate 18 inside the tower body 11, thereby heating the tire oil. The temperature sensor 20 at the center of the upper surface of the heating plate 18 monitors the temperature inside the tower body 11 in real time and transmits the temperature data to the controller 17. The current temperature value is displayed on the display screen 21 of the controller 17. The controller 17 automatically adjusts the power of the coil heater 19 according to the data fed back by the temperature sensor 20 to ensure that the temperature inside the tower body 11 always remains within the preset range. At the same time, the controller 17 sends a start signal to the vacuum pump 13, and the vacuum pump 13 starts to work, pumping out the gas inside the tower body 11 through the connecting pipe 12 to reduce the pressure inside the tower body 11. The pressure sensor 16 at the front part of the upper surface of the tower body 11 monitors the pressure inside the tower body 11 in real time and transmits the pressure data to the controller 17. The current pressure value is displayed on the display screen 21 of the controller 17. The controller 17 automatically adjusts the opening degree of the electric pressure regulating valve 15 according to the data fed back by the pressure sensor 16 and the preset pressure parameter. When the pressure is too high, the controller 17 increases the opening degree of the electric pressure regulating valve 15 to allow more gas to be discharged, reducing the pressure inside the tower body 11; when the pressure is too low, the controller 17 reduces the opening degree of the electric pressure regulating valve 15 to reduce the gas discharge and increase the pressure inside the tower body 11. In this way, it is ensured that the pressure inside the tower body 11 always remains within the appropriate vacuum fractional distillation range. Under the action of heating and vacuum fractional distillation, different components in the tire oil vaporize and rise. The lighter components vaporize first, and the heavier components vaporize at a higher temperature. The vaporized gas enters the condensation device 24 through the gas outlet pipe 23 at the center of the upper surface of the tower body 11. The condensation device 24 uses water cooling or air cooling methods to cool the gas into a liquid, which flows out through the liquid collection pipe 25 for collection and subsequent processing.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
