Description

Technical Field

[0001] This utility model relates to the field of titration technology, and in particular to the reaction disk structure of a laboratory rotary multi-station titrator. Background Technology

[0002] A titrator is an analytical instrument based on the principle of titration analysis, also known as volumetric analysis. It is widely used in the fields of chemistry, medicine, food, and environment to accurately determine the content of specific components in a sample. Its core logic is to slowly add a standard solution titrant of known concentration to the sample to be tested until a quantitative chemical reaction occurs between the two, and then calculate the concentration and content of the analyte based on the amount of titrant consumed.

[0003] Traditional reaction disks mainly rely on stepper motors for direct drive, lacking a real-time position compensation mechanism, which easily leads to problems such as missed steps and overshoot. Even with a simple rotating structure, the manual sample stage of an automatic titrator still requires manual fine-tuning of the sample cup position to complete the titration, which greatly limits the automation efficiency. Existing reaction disks use a three-in-one solution of motor, encoder, and closed-loop control to solve the positioning accuracy problem, but the equipment has poor adaptability, the sample cup size is fixed, and it cannot adapt to the analysis needs of samples of different volumes, making it difficult to meet the analysis of complex samples and failing to meet the user's needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a reaction disk structure for a laboratory rotary multi-station titrator, aiming to improve the poor adaptability of the existing technology and the inability to fix it according to different size specifications.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a laboratory rotary multi-station titrator reaction disk structure, including a base, a clamping mechanism rotatably connected to the top left side of the base, a support column fixedly connected to the top center of the base, a titration mechanism fixedly connected to the top of the support column, the titration mechanism being used for position adjustment, the clamping mechanism including a large rotating disk, the bottom of the large rotating disk rotatably connected to the top left side of the base, multiple fixed frames fixedly connected to the top of the large rotating disk, a top plate fixedly connected to the top of the fixed frames, a motor fixedly connected to the top center of the top of the top plate, a rotating shaft fixedly connected to the output end of the motor, a rotating assembly fixedly connected to the outer wall of the rotating shaft, a rotating column fixedly connected to the middle of the rotating assembly, a grooved plate fixedly connected to the top of the rotating column, a propulsion assembly slidably connected to the top of the grooved plate, a sliding assembly slidably connected to the lower middle part of the outer wall of the propulsion assembly, and a fixed plate fixedly connected to the bottom of the sliding assembly.

The middle of each small gear is fixedly connected to the middle of the rotating column, and the bottom of the rotating column is rotatably connected to the top of the large rotating disk.

[0008] Preferably, the propulsion assembly includes a sliding column, the outer wall of which is slidably connected to the middle of the grooved plate, and a clamp is fixedly connected to the top of the sliding column.

[0012] Preferably, a round cover is fixedly connected to the top of the large rotating disk, and a bearing is fixedly connected to the middle of the top of the fixing plate.

[0013] This utility model has the following beneficial effects: 1. This utility model has flexible adaptability and stable fixing capability.

Specifically, the rotating assembly 206 mainly consists of a large gear 2061, which is connected to the outer wall of the rotating shaft 205 through a central hole. Machined teeth are evenly distributed around the outer circumference of the large gear 2061, and these teeth mesh with the teeth of multiple small gears 2062 arranged around it. This gear meshing transmission mechanism achieves efficient power transmission. The core component of the propulsion assembly 209 is the sliding column 2091. The outer surface of the sliding column 2091 is machined to form a sliding fit with the guide groove in the center of the grooved plate 208. A fixed mounting is installed at the top of the sliding column 2091. The special fixture 2092 is used for clamping and positioning the workpiece. The key component of the sliding assembly 210 is the arc-shaped groove turntable 2101. The turntable is connected and fixed to the outer wall of the rotating column 207 through the mounting hole in its middle. When the arc-shaped groove turntable 2101 rotates, the groove on its surface can guide the top sliding column 2091 to achieve centering movement, thereby completing the automatic clamping and positioning of the workpiece. To ensure rotational stability, a slidingly connected limiting column 2102 is also provided on the outer circumference of the arc-shaped groove turntable 2101.

[0021] Please see the appendix Figure 3 - Appendix Figure 5 The telescopic component 302 includes a cylinder 3021, the outer wall of which is fixedly connected to the bottom of the support plate 301. A flow box 3022 is fixedly connected to the bottom of the cylinder 3021. Pushing the cylinder 3021 allows the dropper head 303 to be adjusted up and down, facilitating titration of the titration cup. The transmission component 307 includes a second motor 3071, the bottom of which is fixedly connected to the bottom of the inner wall of the protective frame 306. A small rotating disk 3072 is fixedly connected to the output end of the second motor 3071. A transmission belt 3073 is connected to the outer wall of the small rotating disk 3072. A round cover 5 is fixedly connected to the top of the large rotating disk 201 to prevent dust from falling inside. A bearing 6 is fixedly connected to the middle of the top of the fixed plate 211 to make the top rotation smoother. Specifically, the telescopic component 302 is mainly composed of a cylinder 3021. The outer wall of the cylinder 3021 is fixed to the bottom of the support plate 301. The bottom of the piston rod of the cylinder 3021 is rigidly connected to the flow box 3022. This structure allows the dropper 303 to be precisely adjusted vertically, thereby realizing the titration operation of the liquid in the titration cup. The core component of the transmission component 307 is the second motor 3071. The motor is firmly installed at the bottom of the inner wall of the protective frame 306 through the base. The output shaft of the second motor 3071 is connected to the small rotating disk 3072 to ensure the reliability of power transmission. The small rotating disk 3072 forms a belt transmission system with the large rotating disk 201 through a specially made transmission belt 3073. A round cover 5 is installed on the top of the large rotating disk 201. This protective cover can effectively prevent dust and impurities from entering the transmission system. A bearing 6 is installed at the center of the top of the fixed plate 211 to ensure that the top rotating component can rotate smoothly and significantly reduce the movement resistance.

[0022] Working principle: The titration cup is placed inside the round cover 5. The motor 204 is controlled to make the large gear 2061 at the output end drive multiple small gears 2062 on the outer wall to rotate. The rotating column 207 in the middle drives the grooved plate 208 and the arc-shaped grooved turntable 2101 at the top to rotate. This causes the sliding column 2091 to converge towards the center along the trajectory inside the arc-shaped grooved turntable 2101, thereby clamping and fixing the titration cup. The edge of the arc-shaped grooved turntable 2101 slides inside the limiting column 2102 to ensure stable rotation. This structure can clamp and fix titration cups of different sizes and specifications, which is convenient for subsequent titration work. The small rotating disk 3072 at the output end is rotated by controlling motor 3071, and the large rotating disk 201 is rotated by transmission belt 3073. The top is pushed by cylinder 3021 to move the flow box 3022 at the bottom up and down. The solution in the volumetric cup 304 flows through the tube 305 and falls into the titration cup through dropper 303. The rotation and alternation titration of multiple stations improves efficiency.
