Description

Technical Field

[0001] This utility model belongs to the field of environmental monitoring technology, specifically relating to a cleaning device for an automatic ion chromatography sample vial. Background Technology

[0002] With rapid industrialization and urbanization, environmental pollution problems have become increasingly serious, especially water pollution, which has become a global concern. Water quality testing is an important component of environmental protection and pollution control. Traditional water quality testing methods, such as gravimetric and titration methods, while highly accurate, are complex, time-consuming, costly, and difficult to implement rapidly. Therefore, developing a rapid, accurate, and low-cost water quality testing technology is of significant practical importance.

[0003] In recent years, ion chromatography (IC) has been widely used in water quality testing due to its advantages such as high efficiency, sensitivity, and ease of operation. Ion chromatography separates different ions through the interaction between ions and the exchange groups on the surface of the chromatographic packing material, enabling the simultaneous detection of multiple ions, and its pretreatment is simple. However, existing automated sample bottle cleaning devices for ion chromatography only have one tool to assist in removing the bottle cap. The cleaning of sample bottles and caps must be done manually one by one, which is time-consuming, labor-intensive, and inefficient. Furthermore, manual cleaning makes it difficult to guarantee the consistency and thoroughness of each cleaning. In addition, human sweat contains a large amount of sodium... + Cl - There is also the possibility of cross-contamination between sweat and sample bottles and caps during manual cleaning.

[0004] In summary, existing automated sample vial cleaning devices for ion chromatography suffer from low cleaning efficiency and poor cleaning quality. Utility Model Content

[0034] Example of a cleaning device for automated sample vials in ion chromatography:

[0035] like Figures 1-3 As shown, the cleaning device for the automated sample vial of ion chromatography includes a robotic arm 1, a tilting mechanism 2, a rinsing mechanism 3 for rinsing the vial body and cap, a lifting mechanism 4, and a waste liquid recovery pipeline 5.

[0036] To facilitate bottle cap removal, the robotic arm 1 includes a base 11, a robotic arm assembly 12, and a cap-removing post 13. One end of the robotic arm assembly 12 is connected to the base 11, and the other end is connected to the cap-removing post 13. The cap-removing post 13 has an external thread on its outer side, which is used to engage with the internal thread of the bottle cap to separate the bottle body and the cap. The robotic arm assembly 12 includes a first sub-arm 121, a second sub-arm 122, a third sub-arm 123, and a fourth sub-arm 124. One end of the first sub-arm 121 is vertically rotatably connected to the base 11, and the other end of the first sub-arm 121 is horizontally rotatably connected to one end of the second sub-arm 122. The other end of the second sub-arm 122 is horizontally rotatably connected to one end of the third sub-arm 123, and the other end of the third sub-arm 123 is vertically rotatably connected to the fourth sub-arm 124. The other end of the fourth sub-arm 124 is fixedly connected to the cap-removing post 13. The robotic arm assembly 12 moves in the circumferential direction by rotating between the first sub-arm and the base 11. The robotic arm 1 moves in the length and height directions by cooperating with the first sub-arm 121, the second sub-arm 122, and the third sub-arm 123. The connection between the bottle cap and the bottle cap 13 is achieved by cooperating with the third sub-arm 123, the fourth sub-arm 124, and the cap-removing post 13, thereby enabling the robotic arm 1 to remove the bottle cap.

[0037] To facilitate the pouring of solution from the sample bottle, the pouring mechanism 2 includes at least one row of fixing frames 21 and a driving mechanism 22. The fixing frames 21 have multiple fixing rings for securing the bottle body, and the driving mechanism 22 drives the fixing frames 21 to rotate, thereby pouring out the waste liquid from the bottle body. Preferably, the fixing frames 21 are arranged in two rows.

[0038] To ensure effective rinsing, the rinsing mechanism 3 includes at least one row of nozzles 31, a supply pipe 32 connected to the nozzles 31, a rinsing container 33 located below the nozzles 31, and a filter container 35 for holding bottle caps. Generally, the cleaning solution sprayed from the nozzles 31 is deionized water. To differentiate the cleaning of the bottle body and bottle cap, a partition 36 is provided in the middle of the rinsing container 33, dividing it into a bottle body area and a bottle cap area. The tilting mechanism 2 is located in the bottle body area, and the filter container 35 is located in the bottle cap area. Because the liquid in the bottle body must be tilted to pour, while the bottle cap does not; and because the bottles must be arranged horizontally to tilt, the bottles occupy a large amount of space, while the bottle caps do not need to be tilted and can be stacked in the filter container 35, utilizing vertical space and reducing the space occupied by the sample bottles. The main function of the partition 36 is to facilitate the fixing of the bracket 21. In this embodiment, the partition 36 does not completely separate the solutions in the bottle body area and the bottle cap area, facilitating the balance of the rinsing solution.

[0039] In order to better control water flow from the filter container 35 to the bottle cap, the lifting mechanism 4 is used to lift the filter container 35.

[0040] To facilitate waste liquid collection, the waste liquid recovery pipe 5 is located below the rinsing mechanism 3, and the rinsing container 33 is connected to the waste liquid recovery pipe via a flexible hose 6.

[0041] Since the bottle caps are stacked together, an ultrasonic cleaning generator is also installed in the bottle cap area to generate ultrasonic waves to clean the bottle caps in order to ensure the cleaning effect of the sample bottles.

[0042] exist Figure 1 and Figure 2 The solution cap is not shown. The rinsing mechanism 3 also includes a container cap 34 and a retractable support frame 37. The container cap 34 is located above the nozzle 31. The support frame 37 passes through the container cap 34 and is connected to the nozzle 31. The support frame 37 drives the container cap 34 to move up and down by extending and retracting, so as to realize the opening and closing of the rinsing container 33.

[0043] To facilitate faster rinsing of sample vials, a valve is installed at the connection between the rinsing container 33 and the hose 6. This valve is used to control the discharge of waste liquid. By simply controlling the valve, the solution inside the rinsing container 33 can be discharged in a controlled manner.

[0044] To ensure the sealing and corrosion resistance of the pipeline, hose 6 is made of polytetrafluoroethylene (PTFE).

[0045] To facilitate the increase in the number of fixtures 21, the drive mechanism 22 includes a motor, a belt, a drive wheel, and a driven wheel. The drive wheel is connected to the drive end of the motor, and the driven wheel is connected to one end of the fixture 21. The belt passes over the drive wheel and the driven wheel. Thus, when adding or removing fixtures 21, only the size and position of the belt need to be adjusted.

[0046] To ensure the automation and precise control of the cleaning process, a controller is also included, which is connected to the robotic arm 1, the tilting mechanism 2, the rinsing mechanism 3, and the lifting mechanism 4.

[0047] To facilitate assembly, the cleaning device also includes a mounting platform 7, on which the robotic arm 1, tilting mechanism 2, and rinsing mechanism 3 are all mounted.

[0048] In practical use, firstly, the sample bottle is placed in the fixing ring of the cleaning device; the cap-removing column 13 of the control robotic arm 1 is connected to the internal thread of the bottle cap to separate the bottle body and the bottle cap, remove the bottle cap from the bottle body and place it in the filter container 35; the telescopic support frame 37 retracts downward so that the solution cap covers the rinsing container 33 to prevent the rinsing liquid from splashing and causing waste; at this time, the bottle body is on the fixing frame 21, and the fixing frame 21 is driven to flip by the drive mechanism 22 to pour out the waste liquid in the bottle body; next, the sample bottle is rinsed by the nozzle 31 in the rinsing mechanism 3; the sample bottle is rinsed and soaked according to the set rinsing process, and the liquid can be changed multiple times by opening and closing the valve during the process; after rinsing, the support member extends and drives the container cap 34 to move upward, the fixing frame 21 flips the bottle body so that the bottle mouth faces downward, the lifting mechanism 4 lifts the filter container 35, the valve opens, and the rinsing liquid flows out from the rinsing container 33; the entire cleaning process is controlled by the program, or the machine can be started manually one by one by setting the buttons.

[0049] The cleaning device for the automatic sample vial of ion chromatography of this invention can achieve efficient and automated cleaning of sample vials and caps, avoiding the shortcomings of manual cleaning and improving the efficiency and accuracy of water quality testing.

[0050] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
