Description

Technical Field

[0001] This utility model relates to the technical field of titration devices for environmental protection testing, and in particular to a titration device for environmental protection testing. Background Technology

[0002] Titration is a quantitative analytical method that determines the content of a solute by the quantitative reaction between two solutions. In chemical experiments, titration typically involves slowly adding a standard solution of known concentration to a solution of unknown concentration until a specific stoichiometric point or titration endpoint is reached. This process can be indicated by the color change of an indicator or other physicochemical methods.

[0003] Existing environmental testing methods require titrating the test sample tubes, typically by titrating each test sample tube in the same batch individually. Furthermore, the test sample tubes must be aligned with the burette during titration, and the process of handling the test tubes also wastes time. Therefore, the titration process is time-consuming and inefficient. To address this, we provide a titration device for environmental testing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies in environmental protection testing, such as low titration efficiency of test sample tubes, and to provide a titration device for environmental protection testing.

[0006] In a preferred embodiment, the I-shaped base has a guide groove inside that matches the guide block. A bearing is sleeved on the outer surface of one end of the rotating rod inside the I-shaped base. The bearing is placed in a groove inside the I-shaped base. The bearing is fixedly connected to the inner wall of the I-shaped base and the outer surface of the rotating rod.

[0007] In a preferred embodiment, the two ends of the spring are respectively fixedly connected to the outer surface of the limiting plate and the inner wall of the I-shaped base.

[0008] In a preferred embodiment, a connecting frame is fixedly connected to the outer surface of the I-shaped base, and an adjustable burette is sleeved inside the connecting frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a titration device for environmental protection testing, comprising: a main body 1, the main body 1 including an I-shaped base 11, a positioning mechanism 2 provided on the top of the I-shaped base 11, the positioning mechanism 2 including a positioning disk 21, a rotating rod 22 passing through the interior of the positioning disk 21, the rotating rod 22 being fixedly connected to the positioning disk 21, one end of the rotating rod 22 passing through the interior of the I-shaped base 11, a slot 23 provided on the positioning disk 21, an arc-shaped surface 24 provided on the positioning disk 21, a semi-circular block 25 provided on one side of the positioning disk 21, a connecting block 26 fixedly connected to one end of the semi-circular block 25, the connecting block 26 passing through the interior of the I-shaped base 11, and the connecting block 25... 6 is slidably connected to the I-shaped base 11. One end of the connecting block 26 is fixedly connected to a limiting piece 27. A spring 28 is provided on one side of the limiting piece 27. A guide block 29 is fixedly connected to the outer surface of the limiting piece 27. There are two guide blocks 29. A guide groove that fits with the guide block 29 is opened inside the I-shaped base 11. A bearing 201 is sleeved on the outer surface of one end of the rotating rod 22 inside the I-shaped base 11. The bearing 201 is placed in a groove opened inside the I-shaped base 11. The bearing 201 is fixedly connected to the inner wall of the I-shaped base 11 and the outer surface of the rotating rod 22. The two ends of the spring 28 are fixedly connected to the outer surface of the limiting piece 27 and the inner wall of the I-shaped base 11, respectively.

[0026] In this embodiment, a positioning mechanism 2 is provided to enable the test tubes of the same batch of samples to rotate in a positioning manner. A slot 23 is provided on the positioning disk 21, which can be used in conjunction with a semi-circular block 25. The engagement of the semi-circular block 25 with the slot 23 is used to maintain the stability of the positioning disk 21. An arc-shaped surface 24 is provided on the positioning disk 21, which can squeeze the semi-circular block 25 when the positioning disk 21 is rotated and adjusted, so that the semi-circular block 25 can slide into the interior of the I-shaped base 11. In addition, a spring 28 is provided, which not only makes the semi-circular block 25 engage more tightly with the slot 23, but also allows the semi-circular block 25 and other components to be reset in time after sliding, and maintains the stability of the position of the positioning disk 21, thereby achieving the purpose of positioning and adjusting the position of the test tubes of the samples. A guide block 29 is provided, which can work with the limiting piece 27 to spring back and reset, so that the limiting piece 27 will not have an uneven springback due to contact with the inner wall of the I-shaped base 11.

[0027] Example 2

[0028] like Figures 1-4 As shown, a connecting frame 12 is fixedly connected to the outer surface of the I-shaped base 11. An adjustable burette 13 is sleeved inside the connecting frame 12. The adjustable burette 13 is fixedly connected to the connecting frame 12. A turntable 14 is provided on one side of the adjustable burette 13. The turntable 14 is fixedly connected to the rotating rod 22. A placement tube 15 is sleeved inside the turntable 14. The placement tube 15 is fixedly connected to the turntable 14. A rotating groove 16 is provided on the turntable 14.

[0029] In this embodiment, by setting an adjustable burette 13, and the position of the adjustable burette 13 is fixed, when the untited test sample tube is adjusted to the bottom of the adjustable burette 13, titration can be completed without alignment. The turntable 14 and the placement tube 15 can be set to place a certain number of test sample tubes, and the position of the test sample tubes can be adjusted by rotating the turntable 14, making the titration more efficient.

[0030] Working principle:

[0031] like Figures 1-4As shown, in use, the test tubes containing the samples to be tested can be placed one by one in the placement tube 15 without any gaps between them. Then, titrant is added to the adjustable burette 13, and titrant is added to one of the sample test tubes placed at the bottom of the adjustable burette 13. After titration, the position of an adjacent sample test tube can be adjusted so that it is placed at the bottom of the adjustable burette 13. At this time, the rotating groove 16 drives the turntable 14 to rotate, and the turntable 14, under the action of the rotating rod 22, drives the positioning plate 21 to rotate. Simultaneously, the positioning plate 21, under the action of the arc surface 24, will press the semi-circular block 25 into the I-shaped base 11, and the semi-circular block 25 will simultaneously drive... The connecting block 26 and the limiting piece 27 slide together, and the limiting piece 27 can compress the spring 28, so that the spring 28 generates elastic force. When the positioning plate 21 rotates another test tube to the bottom of the adjustable burette 13, the restriction of the positioning plate 21 on the semi-circular block 25 will disappear. At this time, the elastic force of the spring 28 will reset the limiting piece 27 and the semi-circular block 25. Since the limiting piece 27 can rebound under the action of the guide block 29, the semi-circular block 25 can just rebound to its original position and engage with the slot 23 opened on the positioning plate 21, so that the positioning plate 21 remains stable again, and then the titration operation can be performed on another test sample test tube until the titration of all test sample test tubes in the same batch is completed.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
