Description

Technical Field

[0002] Raman spectroscopy is a scattering spectrum that analyzes scattered spectra with frequencies different from the incident light to obtain information on molecular vibration and rotation, and is applied to the study of molecular structure. Raman spectroscopy can be used to detect the composition of substances.

[0003] For example, the utility model: "Fully automatic surface enhanced Raman spectroscopy detection device", with the announcement number: "CN212083231U", can automatically extract the solution to be reacted into the stirring unit by setting a feeding unit. The stirring unit can ensure that all the extracted solutions can be fully mixed. The mixed solution is extracted into a U-shaped capillary quartz tube through a first peristaltic pump and reacts in the quartz tube to emit a Raman spectrum. The detection can be completed by only receiving and analyzing the Raman spectrum. However, in the implementation of this patent, the mixed solution is only detected by an electric stirrer, and the mixing effect is poor. It is not easy to mix the solution evenly, making it difficult to keep the solution components uniform, thereby affecting the detection results.

A sliding component 3 is installed on the end of the fixed plate 4 close to the support plate 22, and a sliding plate 6 is slidably installed on the end of the sliding component 3 away from the fixed plate 4. A liquid pump 14 is installed on the end of the top of the support plate 22 close to the fixed plate 4, where the model of the liquid pump 14 can be ISGD. A Raman spectrometer 18 is installed on the end of the top of the support plate 22 away from the fixed plate 4, and a control panel 2 is installed on the bottom of the fixed plate 4 away from the support plate 22. The output end of the control panel 2 is electrically connected to the input ends of the first motor 12, the liquid pump 14 and the second motor 28 through wires.

[0025] In this implementation:

[0026] Furthermore, an L-shaped plate 16 is installed at one end of the top of the support plate 22 close to the fixed plate 4, and a placement hole 29 is provided at the top of the L-shaped plate 16. A capillary quartz tube 17 is installed inside the placement hole 29. By placing the capillary quartz tube 17 inside the placement hole 29, the capillary quartz tube 17 can be placed on the device.

[0027] Furthermore, a first hose 13 extending into the interior of the mixing liquid box 10 is installed at the input end of the liquid pump 14, and a second hose 15 is installed at the output end of the liquid pump 14. The liquid pump 14 extracts the solution from the mixing liquid box 10 through the first hose 13, and extracts the solution into the capillary quartz tube 17 through the second hose 15.

[0028] Furthermore, a stirring shaft 20 extending into the mixing box 10 is installed at the output end of the first motor 12, and stirring rods 19 are evenly installed on the outside of the stirring shaft 20. The first motor 12 drives the stirring rods 19 and the stirring shaft 20 to rotate, thereby stirring the solution.

[0029] Furthermore, one end of the sliding plate 6 away from the sliding assembly 3 is hinged with a connecting rod 5, and one end of the connecting rod 5 away from the sliding plate 6 is hinged to the mixing box 10. The sliding plate 6 drives the connecting rod 5 to move together, so that the connecting rod 5 is subjected to force and drives the mixing box 10 to rotate.

[0030] Furthermore, a rotating shaft 27 is installed at the output end of the second motor 28, and a turntable 8 is installed at the end of the rotating shaft 27 away from the second motor 28, a fixing rod 26 is installed at the edge position of the turntable 8 away from the rotating shaft 27, and a second bearing 25 is installed on the outer side of the fixing rod 26, and a hinged rod 7 is hinged on the outer side of the second bearing 25, and the end of the hinged rod 7 away from the second bearing 25 is hinged to the sliding plate 6.

The device has a high degree of automation and is relatively convenient to use.

[0031] Furthermore, a liquid inlet pipe 11 is installed at one end of the top of the mixing liquid box 10 away from the support plate 22 , and a sealing cover is installed on the top of the liquid inlet pipe 11 to facilitate adding solution into the mixing liquid box 10 .

[0032] Furthermore, a group of reinforcing plates are symmetrically installed on the outer side of the rotating rod 24, and the ends of the reinforcing plates away from the rotating rod 24 are connected to the mixing box 10, so that the rotating rod 24 and the mixing box 10 can be firmly installed.

[0033] Working principle:

[0034] When in use, the device is powered on, and then a proper amount of solution is added into the mixing liquid box 10 through the liquid inlet pipe 11, and then the sealing cover on the liquid inlet pipe 11 is closed;

[0035] During mixing, the staff can start the first motor 12 through the control panel 2, so that the first motor 12 drives the stirring rod 19 and the stirring shaft 20 to rotate, thereby stirring the solution;

[0036] At the same time, the staff can start the second motor 28 through the control panel 2, so that the second motor 28 drives the turntable 8 to rotate at a constant speed through the rotating shaft 27, and the turntable 8 drives the fixed rod 26 to rotate. Since the fixed rod 26 is installed on the inner ring of the second bearing 25, and the hinged rod 7 is installed on the outer ring of the second bearing 25, the hinged rod 7 can rotate independently on the outer side of the fixed rod 26 through the second bearing 25, so that the hinged rod 7 can always face downward;

[0037] When the fixed rod 26 rotates upward, the fixed rod 26 drives the hinged rod 7 to move through the second bearing 25, so that the hinged rod 7 is stressed and pulls the sliding plate 6 to move upward, and the sliding plate 6 drives the connecting rod 5 to move together, so that the connecting rod 5 is stressed and pulls the mixing box 10 to rotate;

[0038] When the fixed rod 26 rotates downward, the fixed rod 26 drives the hinged rod 7 to move through the second bearing 25, so that the hinged rod 7 is stressed and pushes the sliding plate 6 to move downward, and the sliding plate 6 drives the connecting rod 5 to move together, so that the connecting rod 5 is stressed and pushes the mixing box 10 to rotate;

[0039] Since the second motor 28 drives the turntable 8 to rotate at a constant speed through the rotating shaft 27, the hinged rod 7 can repeatedly push and pull the sliding plate 6 to move, and the connecting rod 5 can repeatedly push and pull the mixing box 10 to shake, which can achieve the effect of automatically shaking the mixing box 10, and the precipitated materials deposited at the bottom can be shaken up, so that the solution composition remains uniform, which is conducive to ensuring the accuracy of the detection result;

[0040] After the mixing is completed, the staff can place the capillary quartz tube 17 inside the placement hole 29, and then insert the second hose 15 into the capillary quartz tube 17, and start the liquid pump 14 through the control panel 2, so that the liquid pump 14 draws the solution inside the mixing box 10 into the capillary quartz tube 17, and the solution inside the capillary quartz tube 17 can be detected by the Raman spectrometer 18.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
