Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic liquid phase analyzers, in particular to a high-precision ultrasonic liquid phase analyzer. Background Art

[0002] The core technology of high-precision ultrasonic liquid phase analyzer is to use the propagation characteristics of ultrasonic waves in liquids for analysis. When ultrasonic waves propagate in liquids, their speed, attenuation, scattering and other characteristics will be affected by the properties of the liquid. By measuring the propagation time and intensity changes of ultrasonic waves in liquids, the physical properties and internal structure information of the liquid can be obtained. Compared with traditional analysis methods, ultrasonic liquid phase analyzers have the advantages of non-invasiveness, high precision, fast and convenient. Traditional acoustic liquid phase analyzers require operators to prepare the mobile phase manually, but the preparation process of the mobile phase is complicated, and the degree of mixing of each solvent in the mobile phase affects the data of subsequent experiments. If the solvents in the mobile phase are not mixed evenly, more water phase will be absorbed, resulting in inaccurate experimental data. The high-precision ultrasonic liquid phase analyzer provided by the present invention can fully mix the mobile phase and provide cleaning of the mobile phase bottle while mixing.

[0012] As a preferred technical solution of the present invention, the cleaning brush includes a cleaning brush strip A and a cleaning brush strip B, and the cleaning brush strip A and the cleaning brush strip B are both provided with long rubber products. The long rubber products on the cleaning brush strip A and the long rubber products on the cleaning brush strip B are staggered, and the shapes formed by rotating the cleaning brush strip A and the cleaning brush strip B are consistent with the inner wall of the solvent bottle.

[0013] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0014] 1. This high-precision ultrasonic liquid phase analyzer is configured to lose the support force of the sliding bar by setting the contact roller, and to fix an oscillation column above the contact roller. A spring is sleeved on the outside of the oscillation column, and the two ends of the oscillation column are movably connected to the spring assembly. When the contact roller loses the upward support force, it will produce a downward movement in the vertical direction under the action of gravity. The spring assembly is movably sleeved at both ends of the oscillation column, so that the oscillation assembly is pulled up by the tension of the spring assembly at both ends when it moves downward. A spring A is arranged inside the spring assembly, so that under the action of the spring assembly and gravity, the entire oscillation assembly performs reciprocating oscillations up and down in the vertical direction. A placement bottle sleeve is fixedly connected to the oscillation assembly, and the placement bottle sleeve also performs reciprocating oscillations up and down under the action of the oscillation assembly. A solvent bottle is sleeved in the placement bottle sleeve, and the solvent bottle contains a prepared mobile phase. Driven by the placement bottle sleeve, the solvent bottle oscillates up and down, and the liquid in the solvent bottle also oscillates accordingly. The oscillation drives the three solvents in the solvent bottle to be fully mixed and shaken, thereby avoiding the experimental structure deviation caused by uneven mixing of solvents in the mobile phase, and improving the accuracy of the experimental data.

[0015] 2. This high-precision ultrasonic liquid phase analyzer is fixedly connected to a cleaning column through the bottom of the cylinder, and a cleaning brush strip A and a cleaning brush strip B are fixedly connected to the cleaning column. Both the cleaning brush strip A and the cleaning brush strip B are provided with brush strips, and the brush strips on the cleaning brush strip A and the cleaning brush strip B are staggered. When the cylinder rotates, the cleaning column fixedly connected to the cylinder also rotates, and the cleaning brush strips A and the cleaning brush strip B on the cleaning column rotate along with the rotation of the cleaning column. When the cleaning brush strips A and the cleaning brush strip B rotate, the brush strips thereon will further mix the solvent in the solvent bottle, and because the overall shape of the cleaning brush strips A and the cleaning brush strip B fits the inner wall of the solvent bottle, the inner wall of the solvent bottle can be scraped when they rotate. If solid precipitation occurs and adheres to the inner wall of the solvent bottle during the solvent mixing process, the cleaning brush strips A and the cleaning brush strip B can scrape it in time. When the mobile phase is not being prepared, crystals may also be attached to the inner wall of the solvent bottle. In this case, the inner wall of the solvent bottle can be cleaned separately using cleaning brush A and cleaning brush B to ensure the cleanliness of the solvent bottle and avoid the impact of unclean solvent bottle on experimental data.

[0016] 3. This high-precision ultrasonic liquid phase analyzer can slide on a sliding track by setting a sliding bar, and the shape of the sliding bar is set to be an arc-shaped plate with high sides and low middle. When the sliding bar slides, it intermittently contacts the contact roller arranged above the sliding bar. When the highest point of the sliding bar slides to the bottom of the contact roller, the contact roller contacts the sliding bar, the contact roller is lifted up, and the oscillation component fixedly connected to the contact roller is also lifted up. When the sliding bar continues to slide, the lifted contact roller descends along the arc of the sliding bar. By utilizing the limited length of the sliding bar, the lowest point of the sliding bar does not contact the contact roller. When the sliding bar continues to slide to its lowest point and is aligned with the contact roller, the contact roller does not contact the sliding bar, and the contact roller loses the upward supporting force of the sliding bar, thereby generating vibration in the vertical direction, replacing the manual mixing and shaking of the mobile phase in the solvent bottle, providing convenience for the experimental operators.

[0017] 4. This high-precision ultrasonic liquid analyzer, by movably connecting the two ends of the oscillation component to the spring component, arranging a connector B inside the spring component, respectively sleeved on the two connectors B on the connector A and the connector C, and fixedly connecting a connecting column between the connectors B, by sleeved spring A on the connecting column, it is ensured that the oscillation component can also be subjected to two pulling forces in the horizontal direction under the action of gravity, by arranging spring A and spring B, the oscillation component can realize up and down oscillation, and the mobile phase is mixed by the up and down oscillation of the oscillation component.

[0018] 5. This high-precision ultrasonic liquid analyzer is provided with a fixed plate and a movable hole is opened in the fixed plate to ensure that the oscillation column can smoothly pass through the partition and oscillate up and down in the movable hole. The brush strips on the cleaning brush strips A and the cleaning brush strips B are staggered and distributed at intervals to ensure that the mobile phases on both sides of the cleaning brush strips A and the cleaning brush strips B can mix and flow with each other. The cleaning brush strips A and the cleaning brush strips B are made of rubber material to ensure that the friction between them and the inner wall of the solvent bottle is appropriate and does not damage the solvent bottle.

The long rubber products on the cleaning brush bar A13141 and the long rubber products on the cleaning brush bar B13142 are staggered. The shapes formed by rotating the cleaning brush bar A13141 and the cleaning brush bar B13142 are consistent with the inner wall of the solvent bottle 132.

[0045] Working principle:

[0046] The first step is to flush the ultrasonic liquid analyzer as a whole to ensure the accuracy of subsequent experiments and prepare the mobile phase in advance. When preparing the mobile phase, the mobile phase needs to be thoroughly mixed. It is difficult to achieve a fully mixed state by simply relying on the miscibility of the solvents. Uneven mixing of the mobile phase will cause the retention time of the experimental results to be increasingly advanced, and the solvent filter head generally sinks to the bottom of the bottle, resulting in more water phase being absorbed. The ultrasonic liquid analyzer provided by the present invention requires the operator to prepare the solvent required for preparing the mobile phase and then load the solvent into the solvent bottle 132.

[0047] In the second step, assuming that the preparation of the mobile phase in the previous step requires the use of solvent A, solvent B and solvent C, the order in which they are loaded into the solvent bottle 132 is solvent A, solvent B and solvent C. First, the operator opens the cap of the solvent bottle 132, pours in solvent A, then pours in solvent B, and finally pours in solvent C. When all the solvents are poured in, the cap of the solvent bottle 132 is closed, and the solvent bottle 132 is placed in the bottle holder 133. The material of the bottle holder 133 is retractable soft silicone. As long as it is expanded, the solvent can be placed in the bottle holder 133. The bottom of the bottle 132 is inserted into the bottle sleeve 133, and since the solvent bottle 132 is made of high borosilicate, a certain friction force can be generated between the solvent bottle 132 and the bottle sleeve 133, so that the solvent bottle 132 can be placed in the bottle sleeve 133 more firmly. After placement, the rotating wheel 131 is inserted into the solvent bottle 132 through the hole plug reserved on the solvent bottle 132. Since 1341 and 1342 are both made of rubber products and are relatively thin, it is ensured that they can smoothly pass through the hole plug reserved on the cap of the solvent bottle 132.

[0048] The third step is to turn on the motor connected to the cylinder 1311, and the cylinder 1311 starts to rotate. The rotation of the cylinder 1311 drives the rotation of the protruding pin 1312 fixedly connected to the cylinder 1311. The protruding pin 1312 is sleeved in the annular groove 11141. When the protruding pin 1312 rotates, the annular groove 11141 performs a linear reciprocating motion under the rotation of the protruding pin 1312. When the annular groove 11141 performs a linear reciprocating motion, since the connecting block 11142 is fixedly connected to the annular groove 11141, the connecting block 11142 is fixedly connected to the annular groove 11141. At both ends of the connecting block 11142, the connecting block 11142 also makes a linear reciprocating motion. The two ends of the connecting block 11142 are respectively fixedly connected with the movable rod 1113. The movable rod 1113 makes a linear reciprocating motion along with the movement of the connecting block 11142. The sliding bar 1112 fixedly connected to the movable rod 1113 makes a linear reciprocating motion under the drive of the movable rod 1113. A sliding track 1111 adapted to the sliding bar 1112 is arranged below the sliding bar 1112. When the sliding bar 1112 makes a linear reciprocating motion When the sliding bar 1112 is in the shape of an arc-shaped plate with high sides and low middle, the sliding bar 1112 will intermittently contact with the contact roller 1223 arranged above the sliding bar 1112. When the highest point of the sliding bar 1112 slides to the bottom of the contact roller 1223, the contact roller 1223 contacts the sliding bar 1112, the contact roller 1223 is lifted up, and the oscillating component 1223 fixedly connected to the contact roller 1223 is rotated. 22 is also lifted up, and when the sliding bar 1112 continues to slide, the lifted contact roller 1223 descends along the curvature of the sliding bar 1112. Since the length of the sliding bar 1112 is limited, the lowest point of the sliding bar 1112 is not in contact with the contact roller 1223. Therefore, when the sliding bar 1112 continues to slide to its lowest point and is aligned with the contact roller 1223, the contact roller 1223 is not in contact with the sliding bar 1112, and the contact roller 1223 loses the upward support force of the sliding bar 1112.

[0049] In the fourth step, when the contact roller 1223 in the third step loses the support force of the sliding bar 1112, since the contact roller 1223 is fixedly connected to the oscillation column 12221 above, the oscillation column 12221 is sleeved with a spring outside, and the two ends of the oscillation column 12221 are movably connected to the spring assembly 1221, when the contact roller 1223 loses the upward support force, it will produce a downward movement in the vertical direction under the action of gravity. Since the two ends of the oscillation column 12221 are movably sleeved with the spring assembly 1221, the oscillation assembly 1222 is pulled up by the tension of the spring assembly 1221 at both ends when it moves downward. A spring A12215 is arranged inside 21, so the whole oscillation assembly 1222 oscillates back and forth in the vertical direction under the action of the spring assembly 1221 and gravity. A bottle holder 133 is fixedly connected to the oscillation assembly 1222. The bottle holder 133 also oscillates back and forth under the action of the oscillation assembly 1222. A solvent bottle 132 is sleeved inside the bottle holder 133. The solvent bottle 132 contains the prepared mobile phase. Driven by the bottle holder 133, the solvent bottle 132 oscillates up and down, and the liquid in the solvent bottle 132 also oscillates accordingly. The oscillation drives the three solvents in the solvent bottle 132 to be fully mixed and shaken.

[0050] The fifth step, in the third step, the cylinder 1311 is driven by the external motor to rotate, and a cleaning column 1313 is fixedly connected to the bottom of the cylinder 1311, and a cleaning brush bar A13141 and a cleaning brush bar B13142 are fixedly connected to the cleaning column 1313. The cleaning brush bar A13141 and the cleaning brush bar B13142 are both provided with brush bars, and the brush bars on the cleaning brush bar A13141 and the cleaning brush bar B13142 are staggered. When the cylinder 1311 rotates, the cleaning column 1313 fixedly connected to the cylinder 1311 also rotates, and the cleaning brush bars A13141 and the cleaning brush bar B13142 on the cleaning column 1313 are Brush bar B13142 rotates along with the rotation of cleaning column 1313. When cleaning brush bar A13141 and cleaning brush bar B13142 rotate, the brush bar on them will further mix the solvent in solvent bottle 132. Since the overall shape of cleaning brush bar A13141 and cleaning brush bar B13142 fits the inner wall of solvent bottle 132, they can scrape the inner wall of solvent bottle 132 when they rotate. If solid precipitates and adheres to the inner wall of solvent bottle 132 during the solvent mixing process, cleaning brush bar A13141 and cleaning brush bar B13142 can scrape it in time. When the mobile phase is not prepared, crystals may also be attached to the inner wall of solvent bottle 132. At this time, cleaning brush bar A13141 and cleaning brush bar B13142 can be used to clean the inner wall of solvent bottle 132 separately to ensure the cleanliness of solvent bottle 132.

[0051] Step 6. After the mobile phase is mixed, turn off the motor connected to the cylinder 1311. After the solvent bottle 132 is stable, the mobile phase in the solvent bottle 132 enters the chromatographic component 2, and finally enters the sample bottle component 3 and the waste liquid collection box 4 to complete the analysis and processing of the experimental results.

[0052] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
