Description

Technical Field

[0001] The utility model belongs to the technical field of micro detection, and particularly relates to a portable device for detecting impurity ions in high-purity lithium carbonate. Background Art

[0002] Lithium carbonate is the most important product in the lithium ore industry. Due to its electrochemical reactivity and other unique properties, it is widely used in the synthesis of lithium-ion batteries. With the in-depth research on lithium batteries in the fields of power and energy storage, as an important raw material, Li2CO3 electrodes are facing an increasing market demand.

[0003] When detecting impurity ions in high-purity lithium carbonate, it is usually necessary to transfer the sample to be measured from the field to a fixed position indoors for measurement, which is not conducive to direct measurement on site. Therefore, a portable device for detecting impurity ions in high-purity lithium carbonate is used. The existing portable device for detecting impurity ions in high-purity lithium carbonate has a relatively small overall volume and complete internal parts, which is convenient for direct measurement on site. When detecting impurity ions in high-purity lithium carbonate on site, first place the sample in a colorimetric dish, then place the colorimetric dish containing the sample on the base, and finally push the push-pull frame into the box body, so that the push-pull frame moving inward drives the colorimetric dish on the base to move into the box body for detection. However, during the process of manually pushing the push-pull frame to send the colorimetric dish placed on the base into the box body, the colorimetric dish is likely to shake, resulting in low stability of the placement of the colorimetric dish. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for a portable impurity ion detection device for high - purity lithium carbonate: a portable impurity ion detection device for high - purity lithium carbonate, including a box body 1 and a colorimetric cuvette 6. An L - shaped push - pull frame 4 extending outward is slidably installed inside the box body 1. A base 5 for placing the colorimetric cuvette 6 is fixedly installed at the top of the horizontal and vertical part of the push - pull frame 4. A clamping mechanism 7 is arranged on the base 5, and the clamping mechanism 7 is used for limiting and clamping the colorimetric cuvette 6.

[0022] The clamping mechanism 7 includes a limiting frame assembly and a buckle assembly;

[0023] The buckle assembly is used for locking and fixing the position of the limiting frame assembly;

[0024] And the limiting frame assembly in the fixed state is used for limiting and clamping the colorimetric cuvette 6.

[0025] Please pay special attention to refer to Figure 1 , a display screen 2 for observing detection data is arranged on the outer wall of the box body 1, and a handle 3 for holding by hand is fixedly connected to the top of the box body 1.

[0026] In this embodiment: by moving the push - pull frame 4 in the inward - moving state to drive the colorimetric cuvette 6 limited and clamped on the base 5 to move into the box body 1 for detection, the data of the sample detection completed inside the colorimetric cuvette 6 will be displayed on the display screen 2, which is convenient for the operator to observe the detection data through the display screen 2, and the handle 3 of the operator's hand is convenient for moving and carrying the box body 1.

[0027] Please pay special attention to refer to Figure 3 , the limiting frame assembly includes a T - shaped sliding groove 701, a T - shaped sliding block 702, a pull rod 707, a through groove 708, a spring 709 and two brackets 703, a limiting frame 704; the bracket 703 is L - shaped;

[0028] The T-shaped sliding groove 701 is opened at one end of the top of the base 5 and extends into its interior. The T-shaped slider 702 is slidably connected to the interior of the T-shaped sliding groove 701. A bracket 703 is fixedly connected to the top of the T-shaped slider 702, and another bracket 703 is fixedly connected to the other end of the top of the base 5. The limiting frame 704 is fixedly connected to the bent part of the bracket 703. The through groove 708 is opened on the outer wall of the base 5 and penetrates into the interior of the T-shaped sliding groove 701. The pull rod 707 is slidably connected to the interior of the through groove 708 and extends to its outside. The pull rod 707 is fixedly connected to the T-shaped slider 702. The spring 709 is sleeved on the outer wall of the pull rod 707, and both ends of the spring 709 are fixedly connected to the T-shaped sliding groove 701 and the T-shaped slider 702 respectively.

[0029] In this embodiment: By pulling the pull rod 707 to the outside of the through groove 708 with the hand, the pull rod 707 in the outward movement state drives the T-shaped slider 702 to move outward along the track of the T-shaped sliding groove 701. Then, the T-shaped slider 702 in the outward movement state drives one limiting frame 704 to move away from the other limiting frame 704 through a bracket 703. At the same time, the moving T-shaped slider 702 squeezes the spring 709, and the spring 709 is compressed under force. At this time, the colorimetric cuvette 6 containing the sample is placed in the groove of the base 5. After the colorimetric cuvette 6 is placed, the hand loosens the pull rod 707, so that the pressure of the spring 709 disappears. Then, the spring 709 in the reset state drives the T-shaped slider 702 to move inward along the track of the T-shaped sliding groove 701, and the T-shaped slider 702 in the inward movement state drives one limiting frame 704 to move closer to the other limiting frame 704.

[0030] Please refer specifically to Figure 3 , the two limiting frames 704 in the close state are used to limit and clamp the colorimetric cuvette 6, and the two limiting frames 704 in the separated state are used to release the clamping limit on the colorimetric cuvette 6.

[0031] In this embodiment: The T-shaped slider 702 in the outward movement state drives one limiting frame 704 to move away from the other limiting frame 704 through a bracket 703, and the T-shaped slider 702 in the inward movement state drives one limiting frame 704 to move closer to the other limiting frame 704.

[0032] Please refer specifically to Figure 3 , the buckle assembly includes a clamping groove 705 and a clamping block 706;

[0033] The clamping groove 705 is opened at the docking part of one limiting frame 704, and the clamping block 706 is fixedly connected to the docking part of the other limiting frame 704.

[0034] In this embodiment: The T-shaped slider 702 in the inward movement state drives a limiting frame 704 to approach another limiting frame 704. Then, one limiting frame 704 in the inward movement state drives the clamping block 706 to align and contact the clamping groove 705 on the other limiting frame 704. Since the clamping block 706 has a hemispherical elastic structure, the clamping block 706 is deformed by the force and clamped into the interior of the clamping groove 705. Then, the clamping groove 705 and the clamping block 706 in the clamped state dock and install the two limiting frames 704. Furthermore, the position of one limiting frame 704 is fixed and cannot move.

[0035] Please refer specifically to Figure 3 , the clamping block 706 has a hemispherical elastic structure, and the clamping groove 705 and the clamping block 706 in the clamped state are used to dock and install the two limiting frames 704.

[0036] In this embodiment: Since the clamping block 706 has a hemispherical elastic structure, the clamping block 706 is deformed by the force and clamped into the interior of the clamping groove 705. Then, the clamping groove 705 and the clamping block 706 in the clamped state dock and install the two limiting frames 704.

[0037] Working principle: When it is necessary to detect impurity ions in high-purity lithium carbonate, first place the sample in the colorimetric cuvette 6. At this time, the hand pulls the pull rod 707 outside the through groove 708, so that the pull rod 707 in the outward movement state drives the T-shaped slider 702 to move outward along the track of the T-shaped chute 701. Then, the T-shaped slider 702 in the outward movement state drives a limiting frame 704 to move away from another limiting frame 704 through a bracket 703. At the same time, the moving T-shaped slider 702 compresses the spring 709, and the spring 709 is compressed by the force. At this time, place the colorimetric cuvette 6 containing the sample in the groove of the base 5. After the colorimetric cuvette 6 is placed, the hand loosens the pull rod 707, so that the pressure of the spring 709 disappears. Then, the reset spring 709 drives the T-shaped slider 702 to move inward along the track of the T-shaped chute 701. The T-shaped slider 702 in the inward movement state drives a limiting frame 704 to approach another limiting frame 704. Then, one limiting frame 704 in the inward movement state drives the clamping block 706 to align and contact the clamping groove 705 on the other limiting frame 704. Since the clamping block 706 has a hemispherical elastic structure, the clamping block 706 is deformed by the force and clamped into the interior of the clamping groove 705. Then, the clamping groove 705 and the clamping block 706 in the clamped state dock and install the two limiting frames 704. Furthermore, the position of one limiting frame 704 is fixed and cannot move. Thus, the two limiting frames 704 in the docked and installed state limit and clamp the colorimetric cuvette 6. Finally, push the push-pull frame 4 into the box body 1, so that the push-pull frame 4 in the inward movement state drives the colorimetric cuvette 6 limited and clamped on the base 5 to move into the box body 1 for detection.
