Description

Technical Field

[0001] This application relates to the field of titration testing, and in particular to an automatic potentiometric titration testing device for halogenated products. Background Technology

[0002] Titration testing of braised products typically involves multiple aspects, including the detection of chemical components, microorganisms, residues, and additives. The main focus is on detecting the content of chemical components such as protein, fat, sugar, salt, and moisture in braised products. Potentiometric titration is a method for measuring the potential change during a titration reaction. When the titration reaction reaches the isoelectric point, the concentration of the analyte changes abruptly, causing a sudden jump in the potential of the indicator electrode, thus allowing the endpoint to be determined.

[0003] Potentiometric titration testing equipment determines the titration endpoint by measuring the change in potential. During the titration process, as the titrant is added, the concentration of the analyte changes continuously, causing the potential of the indicator electrode to change accordingly. The structure of a potentiometric titration testing equipment generally consists of a main unit, a burette holder, an operating surface, a lower stirrer, and an electrode telescopic support.

[0004] While existing automatic potentiometric titrators allow for adjustment of electrode height, the electrode telescopic frame is adjusted by sliding a slide bar up and down on a support rod and then securing it with locking bolts. Although this method enables rapid adjustment of electrode height, it becomes cumbersome when fine adjustments are needed. Even a slight slide can cause a large vertical movement, requiring repeated adjustments by the operator to achieve the appropriate height, which is time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art that fine-tuning the height is cumbersome, and even a slight slide can cause a large vertical movement, requiring repeated adjustments by staff to achieve the appropriate height, which is time-consuming and labor-intensive. This application provides an automatic potentiometric titration testing device for braised products.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] An automatic potentiometric titration testing device for braised products includes a main unit, an operating surface mounted on the main unit, a burette holder mounted on the main unit, a lower stirrer mounted on the main unit, an electrode telescopic bracket provided on one side of the lower stirrer, a fine-tuning mechanism provided on the electrode telescopic bracket, and a quick-fixing mechanism provided between the electrode telescopic bracket and the main unit.

[0008] By adopting the above technical solution, the electrode is brought into the test solution by using an electrode telescopic support. Then, the height is finely adjusted to an accurate height using a fine-tuning mechanism before titration begins. During the titration process, the reading of the solution measured by the electrode is read on the operating surface in real time. This reduces the possibility of workers having to repeatedly adjust the electrode telescopic support to achieve the appropriate height, which is time-consuming and laborious. At the same time, it makes the height of the electrode in the test solution more accurate.

[0009] Furthermore, the fine-tuning mechanism includes an adjustment seat 1 mounted on the host, an adjustment seat 2 mounted on the adjustment seat 1, the adjustment seat 2 being fixedly connected to the electrode telescopic bracket, and an adjustment component being provided between the adjustment seat 1 and the adjustment seat 2.

[0010] By adopting the above technical solution, the adjustment component drives the adjustment seat one and the adjustment seat two, allowing the adjustment seat one and the adjustment seat two to move away from or closer to each other. This makes it convenient to make fine adjustments to the electrode height on the electrode telescopic bracket, reducing the possibility of needing to repeatedly adjust to achieve the appropriate height, which is time-consuming and laborious.

[0011] Furthermore, the adjustment assembly includes an adjustment threaded rod disposed between adjustment seat one and adjustment seat two. One end of the adjustment threaded rod passes through adjustment seat one and is threadedly connected to adjustment seat one. The end of the adjustment threaded rod away from adjustment seat one passes through adjustment seat two and is rotatably connected to adjustment seat two. An adjustment knob is fixed to the end of the adjustment threaded rod away from adjustment seat one.

[0012] By adopting the above technical solution, rotating the adjustment knob causes the adjustment screw rod to move the adjustment seat one closer to or further away from the adjustment seat two, thereby making it convenient for the adjustment seat one and the adjustment seat two to move closer to or further away from each other.

[0013] Furthermore, a sliding rod is fixed on the second adjusting seat, the sliding rod passing through the first adjusting seat and being slidably connected to the first adjusting seat.

[0014] By adopting the above technical solution, when adjusting seat 1 and adjusting seat 2 move, adjusting seat 2 drives the sliding rod, allowing the sliding rod to slide on adjusting seat 1. This enables adjusting seat 1 and adjusting seat 2 to move along the direction of the sliding rod, reducing the possibility of misalignment between adjusting seat 1 and adjusting seat 2.

[0015] Furthermore, a limiting block is fixed at the end of the slide rod away from the second adjusting seat, and the limiting block corresponds to the first adjusting seat.

[0016] By adopting the above technical solution, when the adjusting block 1 slides on the slide rod, the limiting block blocks one end of the slide rod, thereby reducing the possibility of the adjusting block 1 falling off the slide rod and the adjusting threaded rod.

[0017] Furthermore, the quick-fixing mechanism includes a support base fixed on the adjustment seat, a fixing block fixed on the support base, a fixing groove corresponding to the fixing block on the main unit, and a snap-fit ​​component provided in the fixing groove.

[0018] By adopting the above technical solution, the support base is fastened to the main unit, the fixing block is inserted into the fixing groove, and then fixed using the snap-fit ​​assembly. This facilitates the fixation of the support base and the electrode telescopic bracket on the support base to the main unit, reducing the possibility of repeatedly loosening bolts to disassemble the electrode telescopic bracket.

[0019] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​block disposed on the host, the host having a movable groove that communicates with a fixed groove, the snap-fit ​​block being located within the movable groove and slidably connected to the host, a retaining spring being disposed within the movable groove, both ends of the retaining spring being fixedly connected to the snap-fit ​​block and the host, and snap-fit ​​teeth being disposed on both the snap-fit ​​block and the fixed block, with opposite orientations.

[0020] By adopting the above technical solution, the fixing block is inserted into the fixing groove, and then, under the push of the resisting spring, the locking teeth on the locking block and the locking teeth on the fixing block are engaged together, so that the fixing block can be easily fixed in the fixing groove.

[0021] Furthermore, a sliding block is fixed on the snap-fit ​​block, and a sliding groove is provided on the host. The sliding groove is connected to the moving groove, and the sliding block is located in the sliding groove and is slidably connected to the host.

[0022] By adopting the above technical solution, the sliding block is moved in the sliding groove, which in turn drives the locking block away from the fixed block, thereby making it easy for the support base to pull the fixed block out of the fixed groove on the host.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when the electrode needs to be inserted into the solution to be tested, the electrode is first adjusted to the approximate height by utilizing the telescopic extension of the electrode support itself. Then, the adjustment knob is turned, which drives the adjustment threaded rod. The adjustment threaded rod drives the adjustment seat one, allowing adjustment seat one and adjustment seat two to move closer or further apart under the restriction of the slide rod. Adjustment seat two drives the electrode on the electrode telescopic support to move. At the same time, the limiting block restricts adjustment seat one, reducing the possibility of adjustment seat one falling off the slide rod and the adjustment threaded rod. This achieves the purpose of conveniently fine-tuning the height of the electrode on the electrode telescopic support, reducing the possibility of repeated adjustments to achieve the appropriate height, which is time-consuming and laborious.

[0025] 2. In this application, when installing the electrode telescopic bracket on the main unit, the support base is first fastened to the main unit, and the fixing block on the support base is inserted into the fixing groove. At the same time, the inclined surface of the locking teeth on the fixing block abuts against the inclined surface of the locking teeth on the locking block, allowing the locking block to move in the moving groove. When the fixing block is fully inserted into the fixing groove, under the push of the abutment spring, the locking teeth on the locking block and the locking teeth on the fixing block are locked together, so that the fixing block is firmly inserted into the fixing groove, completing the fixation between the support base and the main unit. The support base supports the electrode telescopic rod, which achieves the purpose of making it easy to fix the support base and the electrode telescopic bracket on the support base to the main unit, reducing the possibility of repeatedly turning the bolts to disassemble the electrode telescopic bracket.

[0033] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0034] This application discloses an automatic potentiometric titration testing device for braised products.

[0035] Reference Figure 1 and Figure 2 An automatic potentiometric titration testing device for braised products includes a main unit 1, an operating surface 2 mounted on the main unit 1, a burette fixing seat 3 mounted on the main unit 1, a lower stirrer 4 mounted on the main unit 1, an electrode telescopic bracket 5 provided on one side of the lower stirrer 4, a fine adjustment mechanism 6 provided on the electrode telescopic bracket 5, and a quick fixing mechanism 7 provided between the electrode telescopic bracket 5 and the main unit 1.

[0036] When testing braised products, the collected samples are first processed, then a solution is prepared. The prepared solution is then placed on the stirrer 4, and the electrode telescopic bracket 5 is quickly fixed to the main unit 1 using the quick-fixing mechanism 7. The test tube for the titration solution is then placed on the burette holder 3, and the electrode telescopic bracket 5 is used to guide the electrode into the solution to be tested. After fine adjustment to the accurate height using the fine-tuning mechanism 6, titration begins. During the titration process, the reading of the solution measured by the electrode is read on the operating surface 2. By using the electrode telescopic bracket 5 to extend the electrode into the solution to be tested and then using the fine-tuning mechanism 6 to adjust the height of the electrode in the solution, the need for repeated adjustments of the electrode telescopic bracket 5 to achieve the appropriate height can be reduced, which is time-consuming and laborious. At the same time, the height of the electrode in the solution to be tested is made more accurate.

[0037] Reference Figure 2 and Figure 3 The fine-tuning mechanism 6 includes an adjustment seat 61 mounted on the host 1, an adjustment seat 62 mounted on the adjustment seat 61, the adjustment seat 62 being fixedly connected to the electrode telescopic bracket 5, and an adjustment component 63 being provided between the adjustment seat 61 and the adjustment seat 62.

[0038] In addition, the adjustment assembly 63 includes an adjustment threaded rod 632 disposed between the adjustment seat 1 61 and the adjustment seat 2 62. One end of the adjustment threaded rod 632 passes through the adjustment seat 1 61 and is threadedly connected to the adjustment seat 1 61. The end of the adjustment threaded rod 632 away from the adjustment seat 1 61 passes through the adjustment seat 2 62 and is rotatably connected to the adjustment seat 2 62. An adjustment knob 631 is fixed to the end of the adjustment threaded rod 632 away from the adjustment seat 1 61.

[0039] Furthermore, a slide rod 633 is fixed on the second adjusting seat 62, the slide rod 633 passes through the first adjusting seat 61, and is slidably connected to the first adjusting seat 61.

[0040] Furthermore, a limit block 634 is fixed at the end of the slide rod 633 away from the second adjusting seat 62, and the limit block 634 corresponds to the first adjusting seat 61.

[0041] When the electrode is inserted into the solution to be tested, the electrode is first adjusted to the approximate height using the telescopic extension of the electrode support 5. Then, the adjustment knob 631 is rotated, which drives the adjustment threaded rod 632. The adjustment threaded rod 632 drives the adjustment seat 1 61, allowing the adjustment seat 1 61 and the adjustment seat 2 62 to move closer or further apart under the restriction of the slide rod 633. The adjustment seat 2 62 moves the electrode on the electrode telescopic support 5. At the same time, the limiting block 634 restricts the adjustment seat 1 61, reducing the possibility of the adjustment seat 1 61 falling off the slide rod 633 and the adjustment threaded rod 632. By rotating the adjustment threaded rod 632, the adjustment seat 1 61 and the adjustment seat 2 62 can be moved closer or further apart, thus facilitating fine adjustments to the electrode height on the electrode telescopic support 5 and reducing the possibility of repeated adjustments to achieve the appropriate height, which is time-consuming and laborious.

[0042] Reference Figure 2 , Figure 4 and Figure 5 The quick-fixing mechanism 7 includes a support base 74 fixed on the adjustment base 61, a fixing block 71 fixed on the support base 74, and a fixing groove 72 corresponding to the fixing block 71 on the main unit 1. A snap-fit ​​component 73 is provided in the fixing groove 72.

[0043] In addition, the snap-fit ​​assembly 73 includes a snap-fit ​​block 731 disposed on the host 1. The host 1 has a movable groove 733, which is connected to the fixed groove 72. The snap-fit ​​block 731 is located in the movable groove 733 and is slidably connected to the host 1. An abutment spring 734 is disposed in the movable groove 733. Both ends of the abutment spring 734 are fixedly connected to the snap-fit ​​block 731 and the host 1. Snap-fit ​​teeth 732 are disposed on both the snap-fit ​​block 731 and the fixed block 71, and they face opposite directions.

[0044] Furthermore, a sliding block 736 is fixed on the snap-fit ​​block 731, and a sliding groove 735 is provided on the host 1. The sliding groove 735 is connected to the moving groove 733, and the sliding block 736 is located in the sliding groove 735 and is slidably connected to the host 1.

[0045] When installing the electrode telescopic bracket 5 onto the main unit 1, first, fasten the support base 74 onto the main unit 1, allowing the fixing block 71 on the support base 74 to be inserted into the fixing groove 72. Simultaneously, the inclined surface of the locking tooth 732 on the fixing block 71 abuts against the inclined surface of the locking tooth 732 on the locking block 731, allowing the locking block 731 to move within the moving groove 733. Once the fixing block 71 is fully inserted into the fixing groove 72, the locking tooth 732 on the locking block 731 engages with the locking tooth 732 on the fixing block 71 under the push of the abutment spring 734, firmly inserting the fixing block 71 into the fixing groove 72. This completes the fixing between the support base 74 and the main unit 1, allowing the support base 74 to extend and retract the electrode. The rod provides support. When it is necessary to separate the electrode telescopic rod from the main unit 1, the sliding block 736 is directly moved. As the sliding block 736 moves in the sliding groove 735, it drives the locking block 731 away from the fixing block 71. Then, the support base 74 drives the fixing block 71 to be pulled out from the fixing groove 72 on the main unit 1. By inserting the fixing block 71 into the fixing groove 72, the abutment spring 734 pushes the locking block 731, so that the locking block 731 and the fixing block 71 are locked together. This makes it easy to fix the support base 74 and the electrode telescopic bracket 5 on the support base 74 to the main unit 1, reducing the possibility of repeatedly turning the bolts to disassemble the electrode telescopic bracket 5.

[0046] Working principle: When testing braised products, the collected samples are first processed, then a solution is prepared. The support base 74 is then attached to the main unit 1, and the fixing block 71 on the support base 74 is inserted into the fixing groove 72. At the same time, the inclined surface of the locking tooth 732 on the fixing block 71 abuts against the inclined surface of the locking tooth 732 on the locking block 731, allowing the locking block 731 to move in the moving groove 733. When the fixing block 71 is fully inserted into the fixing groove 72, the locking tooth 732 on the locking block 731 is engaged with the locking tooth 732 on the fixing block 71 under the push of the abutment spring 734, so that the fixing block 71 is firmly inserted into the fixing groove 72, completing the fixation between the support base 74 and the main unit 1, and allowing the support base 74 to support the electrode telescopic rod.

[0047] Place the prepared solution onto the lower stirrer 4, and then use the electrode telescopic bracket 5 to extend the electrode into the solution to approximately the desired height. Then, rotate the adjustment knob 631, which drives the adjustment threaded rod 632. The adjustment threaded rod 632 drives the adjustment seat 1 61, allowing the adjustment seat 1 61 and adjustment seat 2 62 to move closer or further apart under the restriction of the slide rod 633. This allows the adjustment seat 2 62 to drive the electrode on the electrode telescopic bracket 5 to make slight movements, so that the electrode is at a suitable height in the solution to be tested, and begin titration. During the titration process, read the reading of the solution measured by the electrode on the operating surface 2 in a timely manner.
