Description

Technical Field

[0001] This application relates to the technical field of spectral torches, and in particular to an ICP spectral torch with an integrated syringe. Background Art

[0002] In the field of modern analytical testing, ICP (Inductively Coupled Plasma) spectrometers have become an important means of elemental analysis due to their advantages such as high sensitivity, wide dynamic linear range, and simultaneous multi-element analysis. To optimize the sample introduction method, an ICP spectral torch with a syringe has emerged. Based on the traditional ICP spectrometer, it realizes precise control of the sample injection volume through the syringe, can achieve micro and stable sample delivery, and is particularly suitable for precious samples or analytical scenarios with extremely high requirements for the injection volume. For example, when detecting the tungsten dissolution amount in a glass pre-filled syringe, the processed sample solution can be accurately injected, greatly improving the accuracy and reliability of the analysis.

[0003] However, the currently widely used ICP spectral torches with syringes have significant defects. In existing designs, many syringes and spectral torches adopt an integrated structure rather than a split installation. This design makes the cleaning of internal residues extremely cumbersome and time-consuming after each liquid suction and injection by the syringe. Since the syringe cannot be conveniently removed from the spectral torch, the cleaning operation needs to be carried out on the overall structure of the spectral torch, making it difficult to comprehensively and efficiently remove the residual substances. More importantly, during the cleaning of the syringe, the entire ICP spectral torch cannot be put into use at the same time, seriously affecting the continuity and efficiency of the detection work. In laboratories or industrial production environments with heavy actual detection tasks, this problem leads to an increase in the idle time of the detection equipment, an increase in the detection cost, and an inability to meet the requirements of fast and high-throughput detection. Therefore, there is an urgent need to innovate and improve the existing ICP spectral torch with an integrated syringe to solve the problems of inconvenient syringe cleaning and inability to detect during cleaning, and to improve the overall performance and practicality of the ICP spectrometer.

Detailed implementation mode

[0018] The following is a further detailed description of this application in conjunction with the attached Figures 1-8 drawings.

[0019] The embodiment of this application discloses an ICP spectral torch with an integrated syringe. As Figures 1-8 shown, it includes a mounting disc 1. The middle of the mounting disc 1 is fixedly installed with a spectral torch body 2. The front of the mounting disc 1 is fixedly installed with a displacement mechanism 3. Both ends of the front of the displacement mechanism 3 are fixedly installed with an adjustment mechanism 4. The front end of the adjustment mechanism 4 is fixedly installed with a syringe mechanism 5. One syringe mechanism 5 is inserted into the inside of the spectral torch body 2; The displacement mechanism 3 includes an annular rail 31 and a first motor 32. The annular rail 31 is fixedly installed on the front of the mounting plate 1. A slip ring 33 is slidably connected inside the annular rail 31. A toothed ring 34 is fixedly installed on the inner side of the slip ring 33. The first motor 32 is fixedly installed in the middle of the upper end of the front of the mounting plate 1. The output end of the first motor 32 is fixedly connected with a gear 35. The gear 35 is meshed with the toothed ring 34. The adjusting mechanism 4 is fixedly installed at the upper and lower ends of the front of the slip ring 33. During use, when it is necessary to adjust the position of the syringe mechanism 5, the first motor 32 in the displacement mechanism 3 is started. The gear 35 at the output end of the first motor 32 rotates accordingly. Since the gear 35 is meshed with the toothed ring 34 fixed to the inner side of the slip ring 33, the rotation of the gear 35 drives the toothed ring 34, and then the slip ring 33 makes a circular slide in the annular rail 31 fixed to the front of the mounting plate 1. The adjusting mechanisms 4 fixed to the upper and lower ends of the front of the slip ring 33 will rotate synchronously with the slip ring 33. The syringe mechanism 5 installed at the front end of the adjusting mechanism 4 also rotates accordingly. In this way, a syringe mechanism 5 can be rotated to be inserted inside the spectral torch body 2 for sample injection detection; the syringe mechanism 5 that has completed injection or needs to be cleaned can also be rotated to a suitable position and further adjusted in cooperation with the adjusting mechanism 4 to achieve flexible control of the device and meet different working requirements.

[0020] Please refer to Figures 1-6 , the adjusting mechanism 4 includes a fixing plate 41. The fixing plate 41 is fixedly installed at the top and bottom of the slip ring 33. A longitudinal adjusting component 43 is fixedly installed at the outer end of the fixing plate 41. A transverse adjusting component 42 is fixedly connected to one side of the longitudinal adjusting component 43. The syringe mechanism 5 is fixedly installed on the front of the transverse adjusting component 42. The longitudinal adjusting component 43 includes a vertical rail 431. The vertical rail 431 is fixedly installed at the outer end of the fixing plate 41. A first lead screw 432 is rotatably connected inside the vertical rail 431. A slider 433 is threadedly connected to the outer surface of the first lead screw 432. A second motor 434 is fixedly installed at the outer end of the vertical rail 431. The output end of the second motor 434 is connected to the outer end of the lead screw. One side of the slider 433 is connected to the transverse adjusting component 42. When it is necessary to adjust the position of the syringe mechanism 5, the second motor 434 at the outer end of the vertical rail 431 in the longitudinal adjusting component 43 is started. The output end of the second motor 434 drives the first lead screw 432 to rotate inside the vertical rail 431. Since the first lead screw 432 is threadedly connected to the slider 433, the rotation of the lead screw will drive the slider 433 to move up and down linearly along the vertical rail 431. The up and down displacement of the slider 433 drives the connected transverse adjusting component 42 to move up and down synchronously. And the syringe mechanism 5 is fixedly installed on the front of the transverse adjusting component 42, so the syringe mechanism 5 will also move up and down accordingly, thereby realizing precise adjustment of the syringe mechanism 5 in the longitudinal position and meeting the requirement of adjusting the syringe mechanism 5 to a suitable height under different working conditions. For example, when installing the syringe mechanism 5, it can reach the entrance of the spectral torch body 2, or when cleaning, it can be moved to a specified height to cooperate with other operations.

[0021] Please refer to Figures 5-8 , the lateral adjustment assembly 42 includes a mounting plate 421, the mounting plate 421 is fixedly connected to one side of the slider 433, an electric push rod 422 is fixedly installed on the mounting plate 421, the output end of the electric push rod 422 penetrates through the mounting plate 421 and is fixedly installed with a base plate 423, the front surface of the base plate 423 is fixedly connected with a mounting sleeve 424, the inner side of the mounting sleeve 424 is fixedly connected with a third motor 425, the output end of the third motor 425 is connected to the syringe mechanism 5, the syringe mechanism 5 includes a fixing frame 51, the fixing frame 51 is fixedly installed at the output end of the third motor 425, a guide rail 52 is fixedly installed inside the fixing frame 51, a second lead screw 53 is rotatably connected inside the guide rail 52, a movable block 54 is threadedly connected to the outer surface of the second lead screw 53, the bottom of the movable block 54 is fixedly installed with a movable frame 55, the rear end of the guide rail 52 is fixedly installed with a fourth motor 57, the output end of the fourth motor 57 is connected to the rear end of the second lead screw 53, the bottom of the fixing frame 51 is fixedly installed with a piston injection assembly 56, the piston injection assembly 56 includes a bottom frame 561, the bottom frame 561 is fixedly installed at the bottom of the fixing frame 51, a base plate 562 is fixedly installed at the inner end of the bottom frame 561, a syringe piston cylinder 563 is fixedly installed inside the base plate 562, the rear end of the syringe piston cylinder 563 is fixedly connected with an injection needle 564, the injection needle 564 is inserted into the spectrochemical torch body 2, a piston body 565 is slidably installed inside the syringe piston cylinder 563, a piston connecting rod 566 is fixedly installed at the outer end of the piston body 565, the outer end of the piston connecting rod 566 is fixedly connected with a connecting frame 567, the top of the connecting frame 567 is fixedly connected with the bottom of the movable frame 55. Through the mutual cooperation of the lateral adjustment assembly 42 and the syringe mechanism 5, the position adjustment and sample injection of the syringe mechanism 5 are realized. When the electric push rod 422 on the mounting plate 421 is started, its output end pushes the base plate 423, and the mounting sleeve 424 connected to the base plate 423 moves accordingly. Since the output end of the third motor 425 inside the mounting sleeve 424 is connected to the fixing frame 51 of the syringe mechanism 5, the syringe mechanism 5 is driven to move back and forth to complete the lateral position adjustment. Starting the third motor 425 can drive the fixing frame 51 to rotate and adjust the angle of the injection needle 564. When performing sample operation, start the fourth motor 57 at the rear end of the guide rail 52, its output end drives the second lead screw 53 to rotate, so that the movable block 54 threadedly connected to the lead screw moves along the guide rail 52, and the movable frame 55 at the bottom of the movable block 54 moves synchronously. The movable frame 55 drives the piston connecting rod 566 through the connecting frame 567, so that the piston body 565 slides inside the syringe piston cylinder 563. When the piston body 565 moves backward, a negative pressure is formed in the cylinder, and the sample can be inhaled from the injection needle 564; when the piston body 565 moves forward, the sample is squeezed from the injection needle 564 into the inserted spectrochemical torch body 2 to realize automatic sample injection.

[0022] Please refer toFigures 1-4 , an installation frame 6 is fixedly installed on the back surface of the installation disc 1. Installation holes 7 are provided at the outer ends of the installation frame 6. The installation holes 7 are countersunk holes. A support fixing ring 8 is fixedly installed at the rear side of the installation frame 6. The overall cross-sectional shapes of the slider 433 and the vertical rail 431 are both in a convex shape. The cross-sectional shapes of the inner part of the guide rail 52 and the movable block 54 are also in a convex shape. A connecting rod 9 is fixedly installed at the bottom of the support fixing ring 8. The front end of the connecting rod 9 is fixedly installed with a cleaning water guiding frame 10. A drain valve 11 is fixedly installed at the front end of the cleaning water guiding frame 10. The input end of the drain valve 11 is communicated with the inside of the cleaning water guiding frame 10. The output end of the drain valve 11 is fixedly connected with a drain pipe 12. The installation frame 6 on the back surface of the installation disc 1 of this device can stably install the ICP spectroscope torch on other devices or structures by using connecting parts such as screws through the countersunk holes at its outer ends. The design of the countersunk holes can make the screw heads sink into the holes, ensuring a flat installation surface and improving the safety and stability of the installation. The support fixing ring 8 at the rear side of the installation frame 6 further enhances the support and stability of the instrument. The connecting rod 9 at its bottom is connected to the cleaning water guiding frame 10, providing a fixed support for the cleaning water guiding frame 10. The slider 433 and the vertical rail 431, as well as the guide rail 52 and the movable block 54, all adopt a convex cross-sectional design. This unique shape can effectively prevent the slider 433 from shifting or disengaging when sliding in the vertical rail 431, and the movable block 54 from shifting or disengaging when sliding in the guide rail 52, ensuring the accuracy and stability of the movement of the components in the adjustment mechanism 4, thereby guaranteeing the reliable operation of the position adjustment of the syringe mechanism 5. When the syringe mechanism 5 needs to be cleaned, the syringe mechanism 5 is moved into the cleaning water guiding frame 10 through the adjustment mechanism 4 for cleaning operations. The sewage generated during the cleaning process will accumulate in the cleaning water guiding frame 10. At this time, the drain valve 11 at the front end of the cleaning water guiding frame 10 is opened. Since the input end of the drain valve 11 is communicated with the inside of the cleaning water guiding frame 10 and the output end is connected to the drain pipe 12, the sewage will flow into the drain pipe 12 through the drain valve 11 under the action of gravity and be discharged, realizing the effective treatment of the cleaning wastewater and keeping the inside of the cleaning water guiding frame 10 clean for the next use.

[0023] The implementation principle of an ICP spectral torch with an integrated syringe in an embodiment of the present application is as follows: In the design of this ICP spectral torch, by setting the displacement mechanism 3 and the adjustment mechanism 4, the overall performance and usability of the device are significantly improved. During the operation of the device, the first motor 32 is started, and the rotation of the motor drives the gear 35 to rotate. Since the gear 35 is in a meshing connection with the toothed ring 34, the slip ring 33 is driven to perform circular sliding inside the annular track 31. The rotation of the slip ring 33 can synchronously drive the two adjustment mechanisms 4 to perform circular motion. When it is necessary to clean the syringe mechanism 5, the syringe mechanism 5 to be cleaned can be moved to the bottom position through the displacement mechanism 3. At this time, with the help of the adjustment mechanism 4, the syringe mechanism 5 can be moved downward to the cleaning water guide frame 10 to carry out the cleaning work. At the same time, the syringe mechanism 5 located at the top can be adjusted accordingly through the adjustment mechanism 4 so that it can be smoothly inserted into the spectral torch body 2 to meet the detection requirements. This device adopts a working mode in which two syringe mechanisms 5 cooperate with each other to achieve continuous and uninterrupted injection operations. During the operation of the instrument, this period of time can be used to clean the syringe mechanism 5 that has been loaded. Through the alternating conversion design of the two syringe mechanisms 5, the overall usability of this device and the use efficiency of the equipment are further improved; The adjustment mechanism 4 of this device plays a crucial role during operation. In actual use, the second motor 434 is started, and the motor operation drives the first lead screw 432 to slide up and down inside the vertical rail 431, thereby driving the slider 433 to move up and down inside the vertical rail 431. Through the displacement of the slider 433, the up and down position adjustment of the lateral adjustment mechanism 4 can be achieved. This function is particularly important when installing the syringe mechanism 5, and it can accurately move the syringe mechanism 5 to the entrance of the spectral torch body 2. Similarly, when it is necessary to clean the syringe mechanism 5, the spectral torch body 2 can be displaced downward through the adjustment mechanism 4 and cooperate with the rotational movement of the displacement mechanism 3 to move it to the bottom for cleaning. In addition, a lateral adjustment component 42 is provided in this device. Before use, the electric push rod 422 is started, and the operation of the electric push rod 422 drives the syringe mechanism 5 to move back and forth, thereby realizing the operation of withdrawing the syringe mechanism 5 from inside the spectral torch body 2 or accurately inserting it into the spectral torch body 2. When the third motor 425 is started, the motor operation drives the fixing frame 51 of the syringe mechanism 5 to rotate. During the process of aspirating the sample solution, the rotation angle of the fixing frame 51 can be adjusted to flexibly adjust the position of the syringe needle, so as to more conveniently aspirate the solution to be fed. It can be seen that the lateral adjustment component 42 and the longitudinal adjustment component 43 cooperate with each other to flexibly adjust the displacement of the syringe mechanism 5 in the front-back, left-right, and up-down directions, realizing the operation of quickly and automatically inserting the syringe mechanism 5 into the spectral torch body 2 or withdrawing it from the spectral torch body 2. Its coordination with the rotational design of the displacement mechanism 3 can flexibly aspirate the sample solution to be detected, and at the same time, the syringe mechanism 5 can also be moved to the bottom for cleaning, realizing the cleaning of the previously used syringe mechanism 5 during the normal operation of the spectral torch body 2, which greatly facilitates the use of this device; The piston injection assembly 56 of the device further optimizes the function of the device. When the device is in use, the fourth motor 57 at the rear end of the guide rail 52 is started, and the motor drives the screw rod to rotate, and the rotation of the screw rod drives the movable frame 55 to move. During the movement of the movable frame 55, the connecting frame 567 is pulled, and then the piston connecting rod 566 is driven, so that the piston body 565 reciprocates inside the syringe piston cylinder 563. When the piston body 565 moves backward, negative pressure can be formed inside the syringe piston cylinder 563. When in use, the injection needle 564 is first moved to the outside through the adjustment mechanism 4, and then the fourth motor 57 is started. The motor drives the third screw rod to drive the piston body 565 to suck the sample solution. When performing the injection operation, the adjustment mechanism 4 is started again to drive the injection needle 564 to be inserted into the interior of the spectral torch body 2. At this time, the fourth motor 57 is started to rotate in the opposite direction, and the motor drives the second screw rod 53 to drive the movable block 54, and the movable block 54 drives the movable The movable frame 55 moves forward, and the movable frame 55 pushes the piston connecting rod 566, thereby driving the piston body 565 to move into the syringe piston barrel 563, prompting the piston body 565 to squeeze the sample solution from the injection needle 564 into the interior of the spectrum torch body 2, thereby realizing the automatic injection function. In addition, during use, when the adjustment mechanism 4 moves the syringe mechanism 5 to the inside of the cleaning water guide frame 10 at the bottom, the fourth motor 57 is started to drive the second screw rod 53 to drive the movable block 54 to move outward. At this time, the movable frame 55 can be driven to pull the piston connecting rod 566 at its bottom to pull the piston body 565 out of the syringe piston barrel 563, so as to facilitate opening the piston body 565 and the syringe piston barrel 563, and to thoroughly clean the piston body 565 and the inside of the syringe piston barrel 563. This automatic injection design is not only convenient and fast for automatic injection, but also can realize fast cleaning and maintenance, greatly improving the convenience of the overall use of the device.
