Abstract
Description
Technical Field
[0001] This utility model relates to the field of instrument sample introduction technology, specifically to an ultrasonic structure for solution volume adjustment in instrument sample introduction. Background Technology
[0002] Before injection into an ICP spectrometer, the raw material must be scientifically prepared to meet the detection requirements. First, determine the dilution ratio of ethanol to pure water based on the raw material concentration and the instrument's detection range. These two are often used together to balance solubility and stability. During the procedure, first measure a fixed amount of pure water into a clean volumetric flask, then add the corresponding volume of the raw material sample. Mix thoroughly, then slowly add ethanol while gently shaking to ensure the solution is homogeneous and does not separate into layers. Finally, bring the volume to the mark. The prepared sample must be immediately transferred to a dedicated injection bottle to avoid contamination or compositional changes, ensuring the accuracy of subsequent detection data.
[0003] However, the existing method of adding liquid involves manual addition and shaking to mix it, resulting in poor accuracy in the addition ratio and poor uniformity of liquid mixing. Utility Model Content
[0004] The purpose of this invention is to provide an ultrasonic structure for solution volume adjustment in an instrument for sample introduction, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic structure for volumetric solution adjustment for instrument sample introduction, comprising an ultrasonic instrument and a support assembly. The ultrasonic instrument has a sample preparation tank inside, and a tank cover is installed on the top of the sample preparation tank. A filling feed pipe is installed on the upper end of the tank cover, and a discharge pipe is provided on the front and rear sides of the filling feed pipe. The support assembly for easy adjustment is located outside the filling feed pipe, and the support assembly includes a fixing frame, a mounting groove, a crossbar, a connecting frame, and a vertical rod. The fixing frame has a mounting groove on its side at the end, and a crossbar is installed inside the mounting groove. The end of the crossbar is connected to the vertical rod through the connecting frame.
[0006] Furthermore, the fixing frame and the mounting slot are an integrated structure, and the fixing frame is connected to the mounting slot and the crossbar by a snap-fit connection.
[0007] Furthermore, a base bracket is installed at the lower end of the vertical rod, and a mounting base plate is connected to the lower end of the base bracket.
[0008] Furthermore, the mounting base plate has edge fixing holes on its side surface, and the mounting base plate and the edge fixing holes are an integrated structure.
[0009] Furthermore, a connecting plate is installed on the upper surface of the mounting base plate, and the number of connecting plates is set to two.
[0010] Furthermore, the upper end of the connecting plate is bolted to a base support, and the lower end of the connecting plate is provided with an auxiliary buffer assembly.
[0011] Furthermore, the buffer assembly includes a rubber pad and a side guard strip, and the side guard strip is installed on the side of the rubber pad.
[0012] Furthermore, the rubber pad is I-shaped, and the rubber pad and the edge strip are an integrated structure.
[0013] This invention provides an ultrasonic structure for solution volume adjustment in an instrument, which has the following advantages: 1. This utility model uses two filling and feeding pipes for ethanol and pure water feeding respectively, allowing for precise addition of a certain proportion of ethanol and pure water to the sample tank. After the ultrasonic instrument is turned on, ultrasonic fusion is achieved, which greatly improves the degree of liquid fusion. The supporting components form a filling platform, and the integrated installation facilitates maintenance. The fixing frame is used for the installation support of the filling and feeding pipes. According to the liquid feeding requirements, the required number of fixing frames can be installed on the crossbar, and the required number of filling and feeding pipes can be added, providing redundancy and scalability for subsequent equipment upgrades. The position of the filling and feeding pipes on the crossbar can also be moved as needed. The mounting groove is used to fix the filling and feeding pipes and also for the installation of the fixing frame on the crossbar. The connecting frame is used for the assembly of the crossbar and the vertical bar. The height of the crossbar on the vertical bar can be adjusted by loosening the bolts.
[0014] 2. This utility model uses a connecting plate to fix the ultrasonic instrument to the mounting base plate. The connecting plate and the base plate absorb a certain amount of vibration when the ultrasonic instrument is working, reducing the vibration transmission during equipment operation. The rubber pad on the connecting plate increases its vibration buffering effect, and the edge strip limits the position from the side bottom connecting plate. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0018] like Figure 1 and Figure 2 As shown, an ultrasonic structure for volumetric solution injection in an instrument includes an ultrasonic instrument 1 and a support assembly 6. The ultrasonic instrument 1 houses a sample preparation tank 2, with a lid 3 on top. A filling feed pipe 4 is installed on the upper end of the lid 3. Two filling feed pipes 4 are used for ethanol and pure water injection, respectively, allowing the sample preparation tank 2 to automatically add a specific ratio of ethanol and pure water with precise addition. When the ultrasonic instrument 1 is activated, ultrasonic fusion significantly improves the liquid mixing degree. The filling feed pipe 4 has outlet pipes 5 on its front and rear sides. The support assembly 6, for easy adjustment, is located outside the filling feed pipe 4, forming a filling platform. The integrated installation facilitates maintenance. The support assembly 6 includes a fixing frame 601, a mounting groove 602, a crossbar 603, a connecting frame 604, and a vertical rod 605. The fixing frame 601 has a mounting groove 602 on its side at one end, used for mounting the filling feed pipe 4. The system is equipped with supports. Depending on the liquid inlet requirements, a number of mounting brackets 601 can be installed on the crossbar 603, and a number of filling feed pipes 4 can be added as needed. This provides redundancy and scalability for future equipment upgrades. The filling feed pipes 4 can also be moved on the crossbar 603 as required. The mounting brackets 601 and the mounting groove 602 are an integrated structure. The mounting groove 602 is used to fix the filling feed pipes 4 and also to install the mounting brackets 601 on the crossbar 603. The crossbar 603 is installed inside the mounting groove 602. The mounting brackets 601 and the crossbar 603 are interlocked through the mounting groove 602. The end of the crossbar 603 is connected to a vertical bar 605 via a connecting bracket 604. The connecting bracket 604 is used for assembling the crossbar 603 and the vertical bar 605. The height of the crossbar 603 on the vertical bar 605 can be adjusted by loosening the bolts. A bottom support 7 is installed at the lower end of the vertical bar 605, and a mounting base plate 8 is connected to the lower end of the bottom support 7.
[0019] like Figure 3As shown, the mounting base plate 8 has side fixing holes 9 on its side surface, and the mounting base plate 8 and the side fixing holes 9 are an integrated structure. A connecting plate 10 is installed on the upper surface of the mounting base plate 8. The connecting plate 10 fixes the ultrasonic instrument 1 to the mounting base plate 8. The connecting plate 10 and the base support 11 absorb a certain amount of vibration when the ultrasonic instrument 1 is working, reducing the vibration transmission during equipment operation. There are two connecting plates 10. The upper end of the connecting plate 10 is connected to the base support 11 by bolts, and the lower end of the connecting plate 10 is provided with an auxiliary buffer assembly 12. The buffer assembly 12 includes a rubber pad 1201 and a side guard strip 1202. The side guard strip 1202 is installed on the side of the rubber pad 1201. The rubber pad 1201 plays a role in increasing the vibration buffering effect of the connecting plate 10. The rubber pad 1201 is I-shaped, and the rubber pad 1201 and the side guard strip 1202 are an integrated structure. The side guard strip 1202 is limited from the side bottom connecting plate 10.
[0020] In summary, the ultrasonic structure for sample introduction and volume determination is based on... Figures 1-3 The structure shown uses bolts to assemble the bottom support 11 and connecting plate 10 of the ultrasonic instrument 1. The connecting plate 10 and bottom support 11 absorb some vibration during operation of the ultrasonic instrument 1, reducing vibration transmission. A rubber pad 1201 is then inserted under the connecting plate 10, allowing the side guard strip 1202 to limit the movement of the connecting plate 10 from the side, thus increasing its vibration damping effect. The vertical rod 605 is then inserted into the bottom bracket 7 and secured with bolts. A connecting bracket 604 is then used to install the horizontal rod 603 on the side of the vertical rod 605. The height of the horizontal rod 603 on the vertical rod 605 can be adjusted by loosening the bolts. Finally, the fixing bracket 601 is installed on the outside of the horizontal rod 603 through the mounting groove 602 on one side, while the mounting groove 602 on the other side is used to fix the filling feed pipe. 4. According to the liquid inlet requirements, the required number of fixing brackets 601 can be installed on the crossbar 603, and the required number of filling feed pipes 4 can be added to provide redundancy and scalability for subsequent equipment upgrades. The position of the filling feed pipes 4 on the crossbar 603 can also be moved as needed. At this time, the entire support assembly 6 forms a filling platform. The integrated installation is convenient for maintenance. During sample preparation, the two filling feed pipes 4, under the action of the metering pump, allow ethanol and pure water to be added to the sample preparation tank 2 respectively, so that the sample preparation tank 2 automatically adds a certain proportion of ethanol and pure water with accurate addition. After the ultrasonic instrument 1 is turned on, the ethanol and pure water inside the sample preparation tank 2 are ultrasonically mixed, which greatly improves the liquid mixing degree. The fixing brackets 601 are used for the installation support of the filling feed pipes 4. After the sample preparation is completed, the mixture is extracted through the discharge pipe port 5.
