[0028] As Figure 4As shown in the figure, the utility model provides a technical solution for an all-range on-line analysis device: The clamping assembly 7 includes an arc-shaped clamping plate one 71, an arc-shaped clamping plate two 72 and a screw rod 74. One end of the screw rod 74 is rotatably connected to a bearing 77, the other end of the screw rod 74 is fixedly connected to a knob 75, the outer wall of the screw rod 74 is threadedly connected to a threaded sleeve 76, the front end of the threaded sleeve 76 is fixedly connected to the rear end of a rubber pad 73, and rubber pads 73 are arranged on the opposite surfaces of the arc-shaped clamping plate one 71 and the arc-shaped clamping plate two 72. By operating and rotating the screw rod 74, the arc-shaped clamping plate two 72 is driven to displace through the threaded sleeve 76 on the screw rod 74, so as to adjust the size of the circular opening between the arc-shaped clamping plate one 71 and the arc-shaped clamping plate two 72. A connection groove 601 is opened on the front end of the mounting plate 6 near one side of the arc-shaped clamping plate two 72, one end of the mounting plate 6 is fixedly connected to a connecting pipe 61, and one end of the outer wall of the screw rod 74 passes through the connecting pipe 61 and extends into the interior of the connection groove 601. The other end of the bearing 77 is fixedly connected to the end of the connection groove 601 away from the connecting pipe 61.

[0029] As Figure 5 shown in the figure, the utility model provides a technical solution for an all-range on-line analysis device: Positioning plates 62 are respectively fixedly connected to the left and right sides of the bottom of the mounting plate 6 near the connection groove 601, a sliding rod 63 is fixedly connected to the opposite surfaces of the two positioning plates 62, an L-shaped slider 731 is fixedly connected to the bottom of the arc-shaped clamping plate two 72, the outer wall of the sliding rod 63 passes through the left and right ends of the middle side of the transverse surface of the L-shaped slider 731, and the outer wall of the sliding rod 63 is slidably connected to the middle side of the transverse surface of the L-shaped slider 731. By rotating the screw rod 74, the sliding rod 63 slides along the inside of the L-shaped slider 731, so as to restrict the movement track of the arc-shaped clamping plate two 72.

[0030] Next, the working principle of the all-range on-line analysis device will be specifically described.

[0031] As Figures 1-5As shown in the figure, when distilling the gasoline to be detected, first, pour the gasoline into the distillation cup body 34 through two vaporization tubes 35 respectively. Then, install the connecting ends of the two temperature sensors 36 at the pipe orifices of the two vaporization tubes 35 respectively. Then, place the two heating cylinders 31 in the two clamping assemblies 7 respectively, with the two heating cylinders 31 sleeved between the arc-shaped clamping plate one 71 and the arc-shaped clamping plate two 72. By rotating the knobs 75 on the two screw rods 74, during the rotation of the screw rods 74, the arc-shaped clamping plate two 72 is driven to move through the threaded sleeve 76, so that the L-shaped slider 731 slides along the outer wall of the slide bar 63, thereby contracting the space between the arc-shaped clamping plate one 71 and the arc-shaped clamping plate two 72, clamping the outer wall of the heating cylinder 31, and making the rubber pads 73 on the inner walls of the arc-shaped clamping plate one 71 and the arc-shaped clamping plate two 72 fit on the surface of the heating cylinder 31, increasing the stability of the clamping of the heating cylinder 31 by the arc-shaped clamping plate one 71 and the arc-shaped clamping plate two 72. Then, inject cold water into the condensation tube 5 through the water inlet pipe 52, and screw the threaded cap 55 onto the water inlet pipe 52. Place the two bearing plates 9 on the distillation range detector 8 respectively, so that the bottoms of the two conduits 4 are perpendicular to the two bearing plates 9 respectively. Then, connect the heating rods 32 in the two heating cylinders 31 to an external power source, and connect the distillation range detector 8 to an external power source through the data line 10. By controlling the heating temperature of the heating rods 32, the temperatures in the two heating cylinders 31 are made different. And the temperatures of the vaporized gasoline transported by the vaporization tubes 35 are detected and observed through the temperature sensors 36 respectively, so that the gasoline in the two distillation cup bodies 34 is heated and vaporized and transported to the conduits 4 through the vaporization tubes 35 respectively, and then enters the condensation tube 5 for condensation, so that the distillate drips into the bearing plates 9. Finally, the distillate in the two bearing plates 9 is detected and analyzed by the distillation range detector 8 to determine the amount of distillate distilled within different temperature ranges. The distillation range detector 8, the temperature sensor 36, the solenoid valve 38 and the heating rod 32 are all existing products, and their internal structures and detection methods will not be elaborated here too much.

[0032] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements without departing from the spirit of the present invention are within the protection scope of the present invention.
