Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of PH value measurement and adjustment, and particularly relates to an automatic PH value measurement and adjustment instrument for processing batch sample extraction solution. BACKGROUND

[0002] PH value measurement and adjustment is a common operation in chemical experiments and many industrial processes, environmental monitoring and other fields. The following is the detailed content about PH value measurement and adjustment: I. Basic concept of PH value, PH value is an index for measuring the acidity and alkalinity of a solution, and its definition is the negative logarithm of the concentration of hydrogen ions (H+) in the solution. At 25 DEG C, a solution with a PH value of 7 is neutral, at which time the concentration of hydrogen ions and the concentration of hydroxyl ions (OH-) are equal, both being 1 x 10-7 mol / L. A solution with a PH value less than 7 is acidic, and the concentration of hydrogen ions is greater than that of hydroxyl ions. A solution with a PH value greater than 7 is alkaline, and the concentration of hydroxyl ions is greater than that of hydrogen ions. For example, a solution with a PH value of 1 has a hydrogen ion concentration of 0.1 mol / L, which is a strongly acidic solution. A solution with a PH value of 13 has a hydroxyl ion concentration of 0.1 mol / L, which is a strongly alkaline solution. PH value needs to be tested by a measurement and adjustment instrument.

[0003] In view of the above problems, the existing measurement and adjustment instrument does not have a good height adjustment function, and cannot adjust the use according to the height of the test tube, so as to affect the test effect, and does not have a good one-by-one detection work, so as to affect the use experience.

The fixing frame 21 is fixedly installed on the top of the base plate 1, and the motor 22 is fixedly installed on one side of the fixing frame 21. A bidirectional threaded rod 23 is fixedly connected to the output end of the motor 22. A movable plate 24 is threadedly connected to the side wall of 23. A trapezoidal block 25 is fixedly installed on one side of the movable plate 24. A second fixed frame 26 is fixedly installed on the top of the base plate 1. A slide rod 27 is slidably connected to the bottom of the second fixed frame 26. A first connecting frame 28 is fixedly connected to the bottom of the slide rod 27. A wheel 29 is connected to the bottom of the first connecting frame 28 through a bearing. A spring 210 is sleeved on the side wall of the slide rod 27. A top plate 211 is fixedly connected to the top of the slide rod 27. Stabilizing plates are fixedly installed on both sides of the movable plate 24. The stabilizing plates are slidably connected to the first fixed frame 21.

[0032] In this embodiment, the motor 22 is first started to drive the bidirectional threaded rod 23 to move, so that the bidirectional threaded rod 23 can drive the movable plate 24 to slide through the fixed frame 21. The movable plate 24 can squeeze the wheel 29 through the trapezoidal block 25. Then the wheel 29 will compress the spring 210 through the connecting frame 28 to retract. At the same time, the slide rod 27 will slide at the bottom of the fixed frame 26, so that the slide rod 27 can drive the top plate 211 to adjust the height, and the adjustment is simple and convenient.

[0034] In this embodiment, the stepper motor 42 is then started to drive the connecting rod 43 to rotate. Then, the electric push rod 44 is turned on to drive the test probe 45 to extend into the test tube 32 to test the sample inside. At the same time, the test probe 45 uses the connecting bracket 46 to drive the marker pen 47 to mark the test tube 32 to prevent repeated testing.

[0035] Working principle: First, starting the motor 22 can drive the bidirectional threaded rod 23 to move, so that the bidirectional threaded rod 23 can drive the moving plate 24 to slide through the fixed frame 21. The moving plate 24 can squeeze the wheel 29 through the trapezoidal block 25. Then the wheel 29 will compress the spring 210 through the connecting frame 28 to retract. At the same time, the slide rod 27 will slide at the bottom of the fixed frame 26, so that the slide rod 27 can drive the top plate 211 to adjust the height.

[0036] Then, starting the stepper motor 42 can drive the connecting rod 43 to rotate. After that, turning on the electric push rod 44 can drive the test probe 45 to extend into the interior of the test tube 32 to perform testing on the sample inside.
