Description

Technical Field

[0001] The present invention relates to the field of titrators, and particularly to an intelligent electrochemical fully automatic titrator. Background Art

[0002] Titration is a classic and widely used method in chemical analysis. Its core principle is to gradually add a titrant with a known concentration to the solution to be tested until the equivalence point of the chemical reaction occurs, so as to accurately determine the concentration of a certain component in the solution to be tested. With the development of science and technology, titrators, as devices to improve the automation and accuracy of titration, have been widely used in laboratories, industrial quality control, environmental monitoring and other fields.

[0003] Although traditional titrators have made significant progress in measurement, existing devices still face some technical challenges in practical applications. The most prominent one is the fusion speed problem of the titrant and the solution to be tested. During the titration process, the release speed of the titrant and the mixing efficiency of the solution to be tested directly affect the progress of the reaction and the titration speed. Specifically, when the titrant enters the solution to be tested, if its diffusion and mixing speed are slow, it will cause a delay in the reaction, thereby prolonging the time of the entire test process. This problem is particularly obvious in solutions with high concentration or high viscosity, because the internal molecular movement of such solutions is slow, further slowing down the reaction rate.

[0034] The following description is essentially exemplary only and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner.

[0035] As Figures 1-12As shown in the figure: This embodiment provides a technical solution: an intelligent electrochemical fully automatic titrator, including a main unit 1. Above the main unit 1, a solution container 3 is detachably assembled through a container stabilizer 2. Above the main unit 1, on one side of the solution container 3, a titration container 7 is detachably installed through a mounting bracket 6. Above the inside of the solution container 3, a burette 330 and a detection electrode 331 are installed. The bottom of the titration container 7 is connected to the burette 330 through a titrant conduit 31. The detection electrode 331 is electrically connected to the main unit 1 through a data transmission line 30;

[0036] The container stabilizer 2 wraps the solution container 3 and is fixed by a pin 23. An assembly groove 13 is opened on the upper surface of the main unit 1 below the solution container 3. Inside the main unit 1, a transmission mechanism 12 is arranged at the central position of the bottom of the container stabilizer 2. A stirring mechanism is arranged below the inside of the solution container 3. The transmission mechanism 12 is detachably docked with the stirring mechanism. Working principle: First, place the test solution in the solution container 3, and then fit the solution container 3 into the container stabilizer 2 from top to bottom, and lock the solution container 3 through the pin 23 on the side, so that the container stabilizer 2 and the solution container 3 form an integral body. Then, snap the container stabilizer 2 into the innermost part of the assembly groove 13 from the edge of the assembly groove 13. At this time, the transmission mechanism 12 inside the main unit 1 is in transmission connection with the stirring mechanism at the bottom of the solution container 3. After the assembly is completed, turn on the main unit. By setting the titration speed of the titrant through the main unit, the titration container 7 gradually drops the titrant into the solution container 3 through the titrant conduit 31 and the burette 330 according to the setting, and mixes and reacts with the test solution in the solution container 3. The transmission mechanism 12 drives the stirring mechanism to stir the solution to accelerate the reaction. During this process, the detection electrode 331 transmits the data signal of the test solution to the main unit 1 through the data transmission line 30, and the main unit 1 analyzes and detects the test solution according to this data signal;

[0037] In summary, this device is equipped with a stirring mechanism at the bottom of the solution container 3. Through the stirring mechanism, the solution inside the solution container 3 can be fully stirred during the titration reaction of the test solution, so that the mixing speed of the titrant and the test solution is faster, thereby improving the reaction efficiency and the test speed. And the transmission mechanism 12 used to control the stirring mechanism is installed inside the main unit 1 and is detachably docked with the stirring mechanism. Therefore, the overall structure of the transmission mechanism 12 will not affect the solution container 3, which is convenient for subsequent processing of the solution container 3. And this split-type transmission structure setting can make the solution container 3 easy to take and place. At the same time, through the setting of the container stabilizer 2, the overall stability of the solution container 3 after assembly can be higher.

[0038] Specifically, as Figures 7-8As shown in the figure, in order to stir the reaction solution inside the solution container 3, in this embodiment, the stirring mechanism includes a main shaft 35 rotatably installed at the bottom of the solution container 3 through a sealed bearing. The top of the main shaft 35 extends into the interior of the solution container 3. A stirring blade 352 is installed on the part of the main shaft 35 extending into the solution container 3 through a stirring rod 351. Based on this, when the main shaft 35 rotates, the stirring blade 352 can be driven to rotate through the stirring rod 351, thereby realizing the stirring of the reaction solution inside the solution container 3 and improving the reaction speed and efficiency.

[0039] Specifically, as Figures 10-12 shown in the figure, in order to realize the rotation control of the main shaft 35, in this embodiment, a cross-shaped groove 350 is opened at the bottom of the main shaft 35. The transmission mechanism 12 includes a transmission shaft 120 rotatably installed inside the main machine 1 through a bearing. A cross-shaped core hole 1200 is opened inside the transmission shaft 120 in the vertical direction. A cross-shaped docking member 121 is movably assembled inside the cross-shaped core hole 1200. The cross-shaped docking member 121 can move up and down in the cross-shaped core hole 1200 so that the cross-shaped docking member 121 can be inserted into the cross-shaped groove 350 when moving upward, realizing the docking of the transmission shaft 120 and the main shaft 35. When the cross-shaped docking member 121 moves downward, the transmission shaft 120 and the main shaft 35 can be separated. Based on this, when it is necessary to disassemble the solution container 3, the cross-shaped docking member 121 can be controlled to move downward to separate the transmission shaft 120 and the main shaft 35, and then the container stable support 2 can be pulled out and removed from the assembly groove 13, and the operation is convenient and fast.

[0040] Specifically, as Figures 11-12As shown, in order to realize that the cross-joint piece 121 can move up and down and transmit the main shaft 35 at the same time, in this embodiment, a movable plate 126 is provided below the transmission shaft 120, and a pull rod 125 is installed at the bottom of the movable plate 126. The upper part of the movable plate 126 is connected to the cross-joint piece 121 through a connecting rod 129. A ring plate 123 is sleeved on the outer bottom of the transmission shaft 120, and a sleeve spring 124 is provided between the ring plate 123 and the movable plate 126. The elastic force of the sleeve spring 124 can keep the cross-joint piece 121 in an upward pop-up state without other external forces. A driven gear 122 is also sleeved on the transmission shaft 120. A cavity 10 is opened at the lower part of the interior of the main machine 1. A motor 127 is fixedly installed in the cavity 10, and a driving gear 128 is connected to the output shaft of the motor 127. The driving gear 128 is meshed with the driven gear 122 for transmission connection. Based on this, when the motor 127 is running, the driving gear 128 and the driven gear 122 drive the transmission shaft 120 and the cross-joint piece 121 to rotate, and the top of the cross-joint piece 121 is inserted into the cross groove 350, thereby realizing the transmission of the main shaft 35 and achieving the effect of split installation. The movable plate 126 can be pulled down by the pull rod 125, so that it drives the cross-joint piece 121 to move down, thereby realizing the separation of the transmission mechanism 12 and the main shaft 35, which facilitates the disassembly of the solution container 3.

[0041] Specifically, such as Figures 1-5 As shown, in order to further realize the detachable installation of the solution container 3 and ensure the stability of the solution container 3 after installation, in this embodiment, a bottom hole 22 for the cross-jointing piece 121 to pass through is opened at the bottom center position of the container stabilizing frame 2, and an edge ring plate 20 and a positioning plate 21 are provided at the lower outer edge of the container stabilizing frame 2. The inner edge of the assembly groove 13 is provided with a flat buckle groove 130 adapted to the edge ring plate 20. When the container stabilizing frame 2 is installed in the assembly groove 13, the edge ring plate 20 is engaged in the flat buckle groove 130, and the positioning plate 21 is pinned from top to bottom in the pin hole 131, so that the horizontal position of the container stabilizing frame 2 is fixed. Based on this, the solution container 3 is fixed in the vertical and horizontal directions, thereby ensuring the stability and safety of the equipment during use.

[0042] Specifically, such as Figure 8 As shown, in order to facilitate the cleaning of the interior of the solution container 3, in this embodiment, a top cover 33 is installed on the top of the solution container 3. The top cover 33 is installed in a detachable snap-fit manner. A sealing ring 333 is provided on the edge of the top cover 33. An annular groove that can adapt to the sealing ring 333 is provided above the solution container 3 at the position for snap-fitting the top cover 33, so that the top cover 33 can be assembled from top to bottom. When the sealing ring 333 is snap-fitted into the inside of the annular groove, it stops, and the assembly of the top cover 33 is completed. It should also be noted that the sealing ring 333 is elastic and the cross-section of the sealing ring 333 is semicircular.

[0043] Specifically, as Figure 1 and 4 - Figure 5 shown, to achieve titration, in this embodiment, a base 4 is installed above the main body 1, the mounting bracket 6 is fixed to the base 4 by bolts, the titration container 7 is clamped within the mounting bracket 6, a piston and a piston rod 70 for controlling the movement of the piston are movably installed above the interior of the titration container 7, a support 8 is installed above the main body 1, a cylinder 9 is fixedly installed at the top of the support 8, and the piston rod of the cylinder 9 is detachably connected to the piston rod 70 through a joint 90.

[0044] Specifically, as Figures 4-5 shown, to achieve the detachable connection between the piston rod of the cylinder 9 and the piston rod 70, in this embodiment, the joint 90 adopts a cylindrical structure with one side open, guiding edges 900 are arranged along the installation direction of the titration container 7 on the inner side of the joint 90, guiding grooves 700 adapted to the guiding edges 900 are formed at the top edge of the piston rod 70, the piston rod 70 can be inserted into the interior of the joint 90 from the open side of the joint 90, and the guiding edges 900 can be clamped within the guiding grooves 700.

[0045] Specifically, as Figures 4-5 shown, to achieve the disassembly of the titration container 7, in this embodiment, a horizontally supported inner groove 60 with an annular structure with one side open is provided inside the mounting bracket 6, at least one limiting annular groove 61 is formed along the horizontal direction on the inner wall of the horizontally supported inner groove 60, a snap ring 72 adapted to the limiting annular groove 61 is installed on the outer wall of the titration container 7, such that when the titration container 7 is clamped within the horizontally supported inner groove 60, the snap ring 72 is clamped within the limiting annular groove 61, at least one threaded locking rod 71 is further provided outside the titration container 7, and a locking hole 62 is formed at the corresponding position on the mounting bracket 6, such that when the titration container 7 is clamped within the horizontally supported inner groove 60, the threaded locking rod 71 is inserted into the locking hole 62, and then the mounting bracket 6 is fixed by installing a nut, thereby achieving the installation of the mounting bracket 6, which is convenient and fast to operate. Additionally, it should be noted that: a bottom tube 73 is installed at the bottom of the titration container 7, a first joint 730 and a second joint 731 are respectively installed on the bottom tube 73, wherein, the second joint 731 is used for connecting the titrant conduit 31, and the first joint 730 is used for connecting with an external titrant container, facilitating the filling of the titrant into the titration container 7.

[0046] Specifically, as Figure 1 、 Figure 2 and Figure 9As shown, in order to balance the air pressure, the inside of the solution container 3 needs to be connected to the outside. To prevent harmful gas pollution, in this embodiment, a filter 34 is installed above the solution container 3. There is an air hole 332 between the filter 34 and the inside of the solution container 3. A gas purifier 5 is also installed above the main body 1. The gas purifier 5 is connected to the filter 34 through a gas conduit 32. Based on this, when the burette 330 is titrating into the solution container 3, the gas generated by the reaction and the gas inside the solution container 3 enter the filter 34 through the air hole 332, and then enter the gas purifier 5 through the gas conduit 32 and are discharged after being purified by the gas purifier 5. It should be noted that: the above-mentioned filter 34 and gas purifier 5 are both commonly used gas treatment devices in the prior art, so their structures are not described in detail.
