[0002] Titration is a means of quantitative analysis and also a chemical experimental operation. It determines the content of a certain solute through the quantitative reaction of two solutions.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Refer to the attached specification Figure 1-4 The utility model is a liquid dispensing titrator for water detection, comprising a titrator body 1, see Figure 3 A motor 2 is fixedly installed inside the titrator body 1, and a rotating member 3 is fixedly connected to the output shaft of the motor 2. The rotating member 3 is rotatably connected to the inside of the titrator body 1. A threaded rod 4 is rotatably connected to the inside of the rotating member 3. A sliding member 5 is threadedly connected to the outer wall of the threaded rod 4. The sliding member 5 is slidably connected to the inside of the rotating member 3. A connecting member 6 is inserted into the inside of the sliding member 5. A card slot 7 is provided inside the sliding member 5 and the connecting member 6. A spring 8 is fixedly installed inside the sliding member 5. An insert rod 9 is fixedly installed at one end of the spring 8. The insert rod 9 is inserted into the inside of the sliding member 5 and the connecting member 6;

[0023] The outer wall of the insertion rod 9 is fixedly mounted with a clamping strip 10 (the spring 8, the insertion rod 9, and the clamping strip 10 are arranged on the outer wall of the insertion rod 9). Figure 3The card slot 7 is shown after being disassembled and pulled, and the card strip 10 is inserted into the card slot 7, the top of the connector 6 is fixedly connected to the mounting plate 11, the inside of the mounting plate 11 is rotatably connected to a bidirectional threaded rod 12, the outer wall of the bidirectional threaded rod 12 is threadedly connected to a slider 13, the slider 13 is slidably connected to the inside of the mounting plate 11, the top of the slider 13 is fixedly connected to a clamping sheet 14, and a rubber anti-skid pad 15 is fixedly installed on one side of the clamping sheet 14, see Figure 1 A burette 16 is fixedly installed inside the titrator body 1 (the burette 16 is coaxial with the center line of the rotating member 3), and a control panel 17 is fixedly installed on one side of the titrator body 1, see Figure 4 The outer wall of the titrator body 1 is provided with a titration liquid bottle 18, see Figure 3 The number of rotating members 3 is set to be multiple, and the outer walls of the multiple rotating members 3 are sleeved with synchronous belts 19.

[0024] It should be noted that, when it is necessary to test the water, first pour the water test sample into the sample bottle and add the indicator, then place the sample bottle into the mounting plate 11 and rotate the bidirectional threaded rod 12, so that the bidirectional threaded rod 12 drives the clamping piece 14 and the rubber anti-skid pad 15 to clamp and fix the sample bottle, so as to achieve the effect of clamping and fixing sample bottles of different sizes to prevent the sample bottles from falling off and being damaged. Then the staff can rotate the threaded rod 4, so that the threaded rod 4 drives the sliding member 5 to slide along the inside of the rotating member 3, and then the sliding member 5 drives the mounting plate 11 and the fixed sample bottle to move through the connecting member 6, so that the bottle mouth of the sample bottle is removed from the burette 16, and finally the staff can pull the insertion rod 9, so that the insertion rod 9 pulls the spring 8 to extend and pull the card strip 10 is disengaged from the card slot 7 provided inside the connecting piece 6. At this time, the staff can rotate the connecting piece 6, the mounting plate 11 and the sample bottle to tilt the sample bottle and align the bottle mouth with the bottom of the burette 16 and then stop. At this time, the staff can reinsert the insertion rod 9 into the interior of the connecting piece 6 for resetting, and reinsert the card strip 10 on the insertion rod 9 into the card slot 7 on the connecting piece 6, so that the card strip 10 passes through the card slot 7 on the sliding piece 5 and the connecting piece 6 to limit and fix the rotation between the sliding piece 5 and the connecting piece 6, so that the connecting piece 6 can no longer rotate, which is convenient for the staff to install the sample bottle in an inclined state according to the shape and size of the sample bottle and align the bottle mouth with the top of the burette 16, so as to facilitate the subsequent shaking and mixing of the sample bottle without the staff manually shaking and mixing the sample bottle;

[0025] Furthermore, at this time, the staff can control the titration speed of the burette 16 and the rotation speed of the motor 2 through the control panel 17, so that the burette 16 titrates the titration liquid into the interior of the sample bottle, and the motor 2 drives the rotating member 3 to rotate through the output shaft, and then the rotating member 3 drives the sample bottle installed in an inclined state to rotate through the sliding member 5, the connecting member 6, and the mounting plate 11, so that the sample bottle mixes the internal liquid and the titration liquid, so as to achieve the effect of automatically shaking and mixing the liquid inside the sample bottle;

[0026] Furthermore, by setting up multiple burettes 16, rotating parts 3 and synchronous belts 19, the staff can titrate and shake multiple sample bottles at one time to improve the processing and detection efficiency of water samples, and can make a comparison directly at one time without the staff having to titrate one by one. The errors of manual titration by the staff can be eliminated, and errors in manual titration can be prevented, which will affect the titration results and improve the titration stability of water detection. At the same time, a flow meter is provided inside the titrator, which will detect the amount of titration liquid titrated by each burette 16 and transmit the result to the control panel 1 for the staff to watch, so that the staff can know the amount of titration liquid required for titration.
