Description

Technical Field

[0002] Inductively coupled plasma spectrometry (ICP) is a widely used and advanced detection method due to its advantages such as low detection limit, small matrix effect, high precision, high sensitivity, wide linear range and simultaneous analysis of multiple elements. It has high requirements for various operations and test solution injection during detection. The test solution for ICP analysis is acid-dissolved with mixed acid or other solutions, and diluted with ultrapure water to a certain volume for testing. The test solution must be in a transparent and pure liquid state. During analysis, the sample is inhaled by the injection capillary and atomized by the atomization system to form a plasma, which is excited in a high temperature and inert argon atmosphere, and the chemical elements in the test solution are determined after passing through the detector.

[0003] In the prior art, a peristaltic pump is used in conjunction with a silicone tube to draw liquid into a filter, and the liquid is then led out through the silicone tube after filtration. The filter is provided with filter paper for filtration. The above method and device are used to achieve the cleanliness of the sample solution for plasma emission spectrometer.

[0028] A stainless steel cylinder 1 and a peristaltic pump 4, wherein a top cover 2 is disposed at the upper end of the stainless steel cylinder 1, and the top cover 2 is connected to the stainless steel cylinder 1 through threaded fitting;

[0029] The metal ring 9 is arranged outside the lower end of the stainless steel cylinder 1, and the metal ring 9 is made of metal iron;

[0030] A fixing platform 11 is arranged at the lower end of the metal ring 9, and an electromagnet ring 10 is arranged outside the upper end of the fixing platform 11;

[0032] Four support springs 13 are provided, and the four support springs 13 are equidistantly distributed along a ring at the lower end of the fixing platform 11 , and a bottom plate 14 is provided at the lower end of the support springs 13 .

[0033] When in use, the vibrator 12 is started, and the vibration generated by the vibrator 12 is transmitted to the stainless steel cylinder 1, so that the stainless steel cylinder 1 and the liquid inside vibrate accordingly, and the filtration efficiency of the liquid is improved under the action of vibration, thereby improving the cleaning efficiency. It should be noted that in order to save space and highlight the innovative elements of this patent, this solution is based on the existing plasma emission spectrometer sample liquid cleaning device, and improves its related structures, such as peristaltic pump 4, silicone tube, filter paper 8, vibrator 12 and other conventional equipment, which will not be repeated in this patent.

[0034] See also Figure 1 , Figure 2 and Figure 3 Four L-shaped side frames 15 evenly distributed along a ring are installed on one side of the upper end of the chassis 14, and the L-shaped side frames 15 are fixedly connected to the chassis 14, and the chassis 14 is used to be placed on a table or other flat surface.

[0035] See also Figure 1 , Figure 2 and Figure 3 A fixing rod 16 is installed inside the L-shaped side frame 15, and a suction cup 17 is installed at the lower end of the fixing rod 16. The suction cup 17 is fixedly connected to the fixing rod 16, and the suction cup 17 adsorbs the table surface so that the fixing rod 16 is fixed.

[0036] See also Figure 2 An inner ring 6 is arranged at the upper end of the stainless steel cylinder 1, and the inner ring 6 is fixedly connected to the stainless steel cylinder 1. A clamping ring 7 is arranged at the upper end of the inner ring 6, and a filter paper 8 is arranged on one side of the lower end of the clamping ring 7. The filter paper 8 is in a bucket shape and is used to filter the liquid.

[0037] See also Figure 1 The output end of the peristaltic pump 4 is provided with an inlet silicone tube 3, and the inlet silicone tube 3 is sealed and fixed to the output end of the peristaltic pump 4, and the other end of the inlet silicone tube 3 is sealed and fixed to the top cover 2, and the inlet silicone tube 3 is used to introduce the liquid into the stainless steel cylinder 1.

[0039] The working principle of this device is as follows: the liquid is pumped into the inlet silicone tube 3 through the peristaltic pump 4. After the liquid enters the stainless steel cylinder 1 from the inlet silicone tube 3, it is filtered by the filter paper 8 and discharged from the outlet silicone tube 5, and then enters the sampling device. In this way, the cleaning process is carried out. When the liquid is filtered, the vibrator 12 is started, and the vibration generated by the vibrator 12 is transmitted to the stainless steel cylinder 1, so that the stainless steel cylinder 1 and the liquid inside vibrate accordingly. Under the action of the vibration, the filtration efficiency of the liquid is improved, thereby improving the cleaning efficiency. When the power is turned off, the electromagnet ring 10 cancels the magnetic adsorption, thereby canceling the adsorption and fixation of the metal ring 9, and the stainless steel cylinder 1 is easy to disassemble and separate. When the chassis 14 is placed on the table, the fixing rod 16 is pressed downward so that the suction cup 17 is squeezed, and the stability of the placement of the chassis 14 is improved by the suction cup 17.
