[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] like Figure 1-3 As shown, the present invention proposes a liquid chromatograph for industrial wastewater detection, which includes a base 1 and a boss 2 installed on the upper part of the base 1.
[0024] The rotating mechanism includes a motor 31 mounted on the boss 2, a rotating shaft 32 mounted on the output end of the motor 31, and a rotating disk 33 sleeved on the outside of the rotating shaft 32;
[0025] The clamping mechanism includes several crossbars 41 installed on the side of the rotating disk 33. The far end of the crossbars 41 is connected to a test tube clamp 42 that opens a clamping range. One end of the test tube clamp 42 is equipped with a sealing plate 43. A self-locking cylinder 44 is provided on one side of the sealing plate 43. A piston rod 45 that penetrates the sealing plate 43 is installed at the output end of the self-locking cylinder 44. The other end of the piston rod 45 is connected to a limiting clamping block 46 that slides along the test tube clamp 42.
[0026] The adjusting mechanism includes an adjusting cylinder 51 located below a test tube clamp 42. The output end of the adjusting cylinder 51 is equipped with a liftable push rod 52, and the other end of the push rod 52 is connected to a test tube holder 53 with a receiving cavity.
[0027] It should be noted that the test tube clamp 42 has a "U-shaped" structure. The limiting clamp 46 slides back and forth along the straight section of the test tube clamp 42. By adjusting the position of the limiting clamp 46 in the test tube clamp 42, the tightness of the test tube clamping can be switched. When the limiting clamp 46 is attached to the test tube, it provides external clamping and limiting for the test tube. When the limiting clamp 46 is away from the test tube, the test tube can move up and down within the test tube clamp 42.
[0028] In this embodiment, multiple test tube clamps 42 are set on the rotating disk 33 to clamp test tubes containing industrial wastewater to be tested in batches. A detection unit is set on one side of the distance adjustment mechanism. The test tube clamp 42 above the test tube support 53 is the detection station. The rotating disk 33 connected to the rotating shaft 32 is driven by the motor 31 to rotate. The test tube clamp 42 and the test tube support 53 are on the same axis, and the detection action is started. At this time, the self-locking cylinder 44 drives the piston rod 45 to reset, which drives the limit clamp 46 away from the test tube. At this time, the distance adjustment mechanism works. The distance adjustment cylinder 51 drives the test tube support 53 connected to the top rod 52 to extend upward, lifting the test tube upward and exposing it. It cooperates with the detection unit to perform liquid chromatography analysis. After completing one detection, each mechanism resets and the detection station is switched. There is no need for manual loading and unloading in the batch detection process, which improves the convenience of detection.
[0029] It is understandable that the concave surface of the limiting clamp 46 is adapted to the test tube specifications, and the end face of the limiting clamp 46 facing the test tube is an elastic element. The purpose of setting the elastic element is to prevent the test tube from being crushed.
[0030] In another embodiment, the auxiliary clamping mechanism includes a support rod 61 disposed below the crossbar 41. An auxiliary tube clamp 62 with the same structure as the top rod 52 is mounted on the support rod 61. The open end of the auxiliary tube clamp 62 is provided with a movable auxiliary clamping plate 65. The auxiliary clamping plate 65 is connected to the limiting clamping block 46 through a connecting rod 64. The test tube clamp 42 and the auxiliary tube clamp 62 clamp the test tube at different positions, thereby improving the stability of the test tube during clamping. At the same time, the test tube clamp 42 and the auxiliary tube clamp 62 can also serve as a guide structure when adjusting the distance of the test tube.
[0031] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
