Currently, it is commonly used for the monitoring of flowing solids and liquids. A probe is installed on the near-infrared spectrometer, and the probe detects the passing materials. When using the near-infrared spectrometer to detect liquid materials, it is necessary to make the liquid to be detected flow through the detection probe position of the near-infrared spectrometer. Therefore, the installation structure of the near-infrared spectrometer determines whether the liquid can be effectively detected by the probe, and at the same time, the installation of the near-infrared spectrometer is realized so as to detect the liquid by the near-infrared spectrometer.

[0023] To clearly illustrate the technical features of this solution, the following is an elaboration of this solution through specific embodiments.

[0024] As Figures 1 - 8 shown, a liquid flow cell installation and adjustment structure of the present utility model includes a near-infrared spectrometer 1 and a liquid pipe 9. The bottom surface of the near-infrared spectrometer 1 is provided with a protruding probe. The probe is a protruding cylindrical structure, and the detection module is located inside the probe for detecting materials.

[0025] It further includes a liquid cell 7 provided on the liquid pipe 9 and a mounting plate 2 attached to the bottom surface of the near-infrared spectrometer 1. The mounting plate 2 is a metal plate, and its shape and size are the same as those of the near-infrared spectrometer 1. The near-infrared spectrometer 1 is detachably fixed to the mounting plate 2.

[0026] The liquid cell 7 is a rectangular block and has a sealed inner cavity inside. The liquid pipe 9 is horizontally arranged and connected to both ends of the liquid cell, so that the liquid material in the liquid pipe 9 flows through the liquid cell 7.

[0027] A detection port is opened at the upper end of the liquid cell 7. The detection port is a circular opening, and a sapphire glass plate 8 is installed on the detection port. The sapphire glass plate 8 is a circular plate and its size is larger than the detection port. An annular sealing gasket is installed between the sapphire glass plate 8 and the detection port to prevent the liquid from flowing out at the detection port position.

[0028] The mounting plate 2 is located above the sapphire glass plate 8. The mounting plate 2 is connected to the liquid cell 7 by bolts and presses the sapphire glass plate 8 against the detection port. Specifically, an annular protrusion 10 is provided on the upper end surface of the liquid cell 7. The annular protrusion 10 is concentric with the sapphire glass plate 8. The sapphire glass plate 8 is located inside the inner circle of the annular protrusion 10. An annular groove adapted to the annular protrusion 10 is provided on the bottom surface of the mounting plate 2, and the annular protrusion is inserted into the annular groove. A circle of threaded holes is opened on the upper end surface of the annular protrusion 10, and bolt holes adapted to the threaded holes are opened on the mounting plate 2. Bolt head counterbores are opened at the upper ends of the bolt holes.

[0029] An exhaust port 12 communicating with the side of the detection port is formed on the side of the liquid pool 7. A plug is installed on the exhaust port 12. The exhaust port 12 is horizontally arranged, with its inner end communicating with the upper end position on the side of the exhaust port 12, and a plug is installed at the outer end. The plug can be connected to the end of the exhaust port 12 by threads.

[0030] A flow-blocking protrusion 11 is provided on the bottom surface of the inner cavity of the liquid pool 7. The flow-blocking protrusion 11 is a smooth protrusion structure and is located directly below the sapphire glass plate 8. Since the cross-section of the inner cavity of the liquid pool is larger than that of the liquid pipe, the provided flow-blocking protrusion guides the liquid upward so that it flows through the position of the probe.

[0031] In order to achieve the detachable fixation of the near-infrared spectrometer 1, connecting screws 4 are hinged at both ends of the mounting plate 2. Specifically, protruding connecting parts are provided at both ends of the mounting plate 2, and one end of the connecting screw 4 is hinged to the connecting part, and the hinge axis is parallel to the mounting plate 2, enabling the connecting screw 4 to swing up and down.

[0032] The ear plate 3 is a horizontal plate and its lower end is flush with the lower end of the near-infrared spectrometer 1. A screw groove adapted to the connecting screw 4 is formed at the end of the ear plate 3. Here, the end refers to the end of the ear plate 3 away from the near-infrared spectrometer 1. The width of the screw groove is slightly larger than the diameter of the connecting screw 4, and the depth of the screw groove is 2-4 times the diameter of the connecting screw 4.

[0033] A connecting nut 5 for pressing the ear plate 3 against the mounting plate 2 is installed on the connecting screw 4. The connecting nut 5 is a wing nut.

[0034] A probe hole through which the probe passes is formed on the mounting plate 2 and the probe hole is located above the sapphire glass plate 8. The probe hole is a circular hole and its diameter is equal to the diameter of the probe. The thickness of the mounting plate 2 is equal to the length of the probe, so that the lower end surface of the probe fits against the upper end surface of the sapphire glass plate 8.

[0035] The usage method of the present utility model:

[0036] During installation, first place an annular sealing gasket on the detection port, place the sapphire glass plate 8 on the annular sealing gasket within the inner ring of the annular protrusion 10, place the mounting plate 2 on the liquid pool 7, and insert the annular protrusion 10 on the liquid pool 7 into the annular groove at the bottom surface of the mounting plate 2. Connect and fix the mounting plate 2 and the liquid pool 7 through bolts, thereby realizing the fixation of the sapphire glass plate 8.

[0037] Place the near-infrared spectrometer 1 on the top surface of the mounting plate 2, insert the probe of the near-infrared spectrometer 1 into the probe hole of the mounting plate 2, then swing the connecting screw 4 so that the connecting screw 4 swings into the screw groove at the end of the ear plate 3, and tighten the connecting nut 5 to fix the near-infrared spectrometer 1. The liquid material flows under the sapphire glass plate 8, and the material is detected through the probe. When there is gas in the liquid cell 7, open the plug of the exhaust port 12 to release the gas.
