[0031] In order to clearly and completely describe the purpose, technical solution of the present utility model and make its advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0032] Embodiment 1: Please refer to Figures 1 to 7 , the present utility model provides a technical solution: a raw material bottle, including a bottle body 1, a feeding pipe 2 is installed at the top of the bottle body 1, a sealing cover 3 is inserted at the top of the feeding pipe 2, a fixing pipe 5 is installed on the right side of the bottle body 1, a top cover 4 is arranged at the top of the fixing pipe 5, sliding grooves 6 are respectively opened on the left and right sides inside the top cover 4, a moving plate 7 is inserted into the inner wall of the sliding groove 6, and the left and right moving plates 7 are in contact with each other; the left and right moving plates 7 are symmetrically arranged, and the adjacent sides of both penetrate through the inner wall of the top cover 4, so as to conveniently fix the position of the thermocouple and improve the accuracy of temperature detection.

[0033] First, drive the two moving plates 7 to move away from each other. At this time, the thermocouple can penetrate through the top cover 4 and be inserted into the bottle body 1. After completion, the two moving plates 7 move towards each other, thereby clamping the outside of the thermocouple, further increasing the stability of its installation and preventing it from sliding unstably. Subsequently, the raw material oil is poured into the inner wall of the bottle body 1 through the feeding pipe 2, and the temperature is increased by electric heating. At the same time, the temperature is monitored in real time by the thermocouple for subsequent analysis results.

[0034] Embodiment 2: On the basis of Embodiment 1, in order to conveniently drive the two moving plates 7 to clamp the thermocouple, moving grooves 12 are respectively opened on the upper left and right sides of the top cover 4. A limiting plate 8 is installed on the inner wall of the moving groove 12. The limiting plate 8 is conveniently pushed by an elastic member 13 and drives the connecting rope 9 to reset, thereby driving the two moving plates 7 to move towards each other and clamp the thermocouple to improve the accuracy of its temperature monitoring. Elastic members 13 are respectively installed on the separated sides of the left and right limiting plates 8. A knob 10 is inserted into the rear side of the top cover 4. A rotating plate 11 is installed at the front end of the knob 10. Connecting ropes 9 are installed on the upper and lower sides of the knob 10; the rotating plate 11 is rotatably connected to the inner rear side of the top cover 4. The connecting rope 9 penetrates through the moving groove 12, and the adjacent ends of the left and right connecting ropes 9 are respectively installed with the limiting plate 8. The adjacent sides of the left and right limiting plates 8 penetrate through the sliding groove 6 and are installed with the moving plate 7. Thus, by rotating the knob 10, the two connecting ropes 9 are wound around the outside of the knob 10, thereby driving the two moving plates 7 to move away from each other. The separated sides of the left and right elastic members 13 are respectively installed on the inner wall of the moving groove 12, so as to utilize the elastic force of the elastic member 13 to conveniently drive the moving plate 7 to reset.

[0035] First, rotate the knob 10 to drive the rotating plate 11 at its front end to rotate synchronously, thereby driving the two connecting ropes 9 to wind around the outside of the knob 10. Since one end of the connecting rope 9 is installed between the limiting plate 8, the limiting plate 8 is driven to slide along the inner wall of the moving groove 12, and the elastic member 13 is squeezed against the inner wall of the moving groove 12. At the same time, the two moving plates 7 are driven to move away from each other. At this time, the thermocouple can penetrate through the top cover 4 and be inserted into the inside of the bottle body 1. After completion, release the knob 10, so that the elastic force of the elastic member 13 itself drives the limiting plate 8 to reset, and drives the two moving plates 7 to move towards each other, thereby clamping the outside of the thermocouple, and further increasing the stability of its installation to prevent the situation of unstable sliding. Subsequently, the raw material oil is poured into the inner wall of the bottle body 1 through the feeding pipe 2, and the temperature is increased by electric heating. At the same time, the temperature is monitored in real time by the thermocouple for subsequent analysis results.

[0036] Embodiment 3: On the basis of Embodiment 2, in order to increase the sealing performance of the thermocouple installation and facilitate the subsequent disassembly of the top cover 4, a rubber bump 14 is installed at the bottom of the top cover 4. An insertion part 15 is sleeved outside the rubber bump 14, and a rubber ring 16 is installed outside the insertion part 15; the top end of the insertion part 15 is installed at the bottom of the top cover 4, and the outside of the insertion part 15 is attached to the inner wall of the fixed pipe 5. Thus, when the thermocouple is inserted downward, it squeezes the rubber bump 14 to expand outward, thereby increasing the sealing performance of the thermocouple insertion; the outside of the rubber ring 16 is attached to the inner wall of the fixed pipe 5, and the rubber ring 16 is in a state of extrusion deformation, so as to increase the sealing performance between the insertion part 15 and the fixed pipe 5 by using the rubber ring 16, and further improve the monitoring effect.

[0037] When inserting the thermocouple, the outside of it will contact the inner wall of the rubber bump 14 and penetrate through the rubber bump 14. At this time, the rubber bump 14 will be squeezed to expand outward, and at the same time, the insertion part 15 will be pushed to be extruded outward. When the thermocouple is completely inserted into the inside of the bottle body 1, at this time, the insertion part 15 is closely attached to the inner wall of the fixed pipe 5, and the rubber ring 16 is driven to be in a state of extrusion deformation, thereby increasing the sealing performance between the insertion part 15 and the fixed pipe 5, and further improving the sealing performance of the thermocouple during monitoring to increase the accuracy of subsequent analysis results.

[0038] Embodiment 4: Please refer to Figure 8 , on the basis of Embodiment 3, a raw material aromatic hydrocarbon distribution recognition device is proposed, including a raw material bottle.

[0039] Embodiment 5: On the basis of Embodiment 4, in order to be able to well identify the distribution of aromatic hydrocarbons in the raw material, a raw material aromatic hydrocarbon distribution recognition device further includes a distillation column 22, a condensation device 23, a collection device 24 and a pressure regulation system 26; the raw material bottle 21 is sequentially connected to the distillation column 22, the condensation device 23 and the collection device 24;

[0040] Among them, the pressure regulating system 26 is configured to regulate the internal pressure of the system composed of the raw material bottle 21, the distillation column 22, the condensation device 23, the collection device 24, etc.

[0041] Exemplarily, the pressure regulating system 26 includes a variable frequency vacuum pump, and the variable frequency vacuum pump is connected to any one of the raw material bottle 21, the distillation column 22, the condensation device 23, and the collection device 24 to regulate the internal pressure of the raw material bottle 21, the distillation column 22, the condensation device 23, and the collection device 24.

[0042] Exemplarily, the condensation device 23 includes a condensation heat exchanger, and the condensation heat exchanger includes an oil-gas heat exchange part 231 and a cooling part 232, and the cooling part 232 is connected to the chiller 25;

[0043] Or / and, the collection device 24 includes a plurality of collection test tubes 241 (the number of collection test tubes 241 is reasonably set according to the actual situation, please refer to Figure 8 , there are 4 collection test tubes 241 in total) and a collection container 242, the plurality of collection test tubes 241 are arranged in the collection container 242, and the pressure regulating system 26 is connected to the collection container 242.

[0044] Specifically, add the raw material oil to the raw material bottle. The raw material bottle is equipped with a thermocouple and is heated electrically to 300 - 420 °C. By controlling the variable frequency vacuum pump, regulate the internal pressure of the raw material bottle 21, the distillation column 22, the condensation device 23, the collection device 24, etc., and the pressure is controlled at 10 - 50 kPa (absolute pressure). The raw material oil evaporates to form a gas-liquid phase. The gas-liquid phase material passes through the distillation column. There are 2 - 5 trays and packing in the distillation column for separating the material. Then, through the condensation heat exchanger, the temperature of the oil and gas is reduced to 50 °C and collected in the collection test tube. By adjusting the temperature of the raw material oil heating and the pressure of the raw material bottle 21, the distillation column 22, the condensation device 23, the collection device 24, etc., the cutting of materials in different distillation ranges can be realized. By calculating the pressure and temperature under reduced pressure and atmospheric pressure, different distillation ranges can be obtained. Detect the different distillation ranges and analyze the content and existence form of aromatics in each distillation range.

[0045] During actual use, first rotate the knob 10 to drive the rotating plate 11 at its front end to rotate synchronously, thereby driving the two connecting ropes 9 to wind around the outside of the knob 10. Since one end of the connecting rope 9 is installed between the limiting plate 8, the limiting plate 8 is driven to slide along the inner wall of the moving groove 12, and the elastic member 13 is squeezed against the inner wall of the moving groove 12. At the same time, the two moving plates 7 are driven to move away from each other. At this time, the thermocouple can penetrate through the top cover 4 and be inserted into the inside of the bottle body 1. After completion, loosen the knob 10, and then use the elastic force of the elastic member 13 itself to drive the limiting plate 8 to reset, and drive the two moving plates 7 to move towards each other, thereby clamping the outside of the thermocouple, and further increasing the stability of its installation to prevent the situation of unstable sliding. Subsequently, the raw material oil is poured into the inner wall of the bottle body 1 through the feed pipe 2, and the temperature is increased by electric heating. At the same time, the temperature is monitored in real time by the thermocouple for subsequent analysis results;

[0046] When inserting the thermocouple, its outside will contact the inner wall of the rubber bump 14 and penetrate through the rubber bump 14. At this time, the rubber bump 14 will be pushed to expand outwards, and at the same time, the insertion part 15 will be pushed to squeeze outwards. When the thermocouple is completely inserted into the inside of the bottle body 1, at this time, the insertion part 15 is in close fit with the inner wall of the fixed pipe 5, and the rubber ring 16 is driven to be in a squeezed deformation state, thereby increasing the sealing performance between the insertion part 15 and the fixed pipe 5, and further improving the sealing performance of the thermocouple during monitoring to increase the accuracy of subsequent analysis results.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
