Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing, and in particular to a titration device for environmental testing. Background Technology
[0002] A titration apparatus is an experimental device used in chemical analysis to quantitatively determine the content of a component in a solution. It involves gradually adding a reagent of known concentration to the solution until the reaction is complete, thereby calculating the concentration of the analyte.
[0003] During environmental testing, a burette on the stand is used to titrate reagents into the test vials. The samples inside the vials then react to detect harmful substances. The burette is equipped with multiple electrodes to monitor sample changes in real time, helping to determine the reaction endpoint and automatically stop the titration. However, when testing multiple samples, the vials need to be constantly secured and replaced, leading to numerous operational steps and potentially impacting the efficiency of the titration apparatus. Utility Model Content
[0004] The technical problem this invention aims to solve is that when conducting environmental testing on multiple samples inside test bottles, the test bottles need to be constantly fixed and replaced, resulting in numerous operational steps and thus affecting the efficiency of the titration device.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a titration device for environmental protection testing, including a support, a burette is provided on one side of the support, and a limiting adjustment device is provided on one side of the support. The limiting adjustment device limits and adjusts the position of the test bottle by placing a block.
[0006] The aforementioned components achieve the following effects: During environmental testing, the burette on the support drips the reagents into the test bottle, and the sample inside the test bottle reacts to detect harmful substances. The burette is equipped with multiple electrodes to monitor the changes in the sample in real time, helping to determine the reaction endpoint and automatically stop the dripping. When conducting environmental testing on multiple test bottles, a limit adjustment device can be used to limit and fix multiple test bottles at the upper end of the support, and then the multiple test bottles are moved sequentially to the burette for titration testing.
[0007] Preferably, the limiting adjustment device includes a round rod, a fixing block, a first bolt, a placement block, a second bolt, and a limiting plate. The round rod is located at the upper end of the bracket, the fixing block is located at the upper end of the round rod, the first bolt is inserted into one side of the fixing block, the placement block rotates on the surface of the round rod, and a plurality of placement grooves are formed on the circumference of the surface of the placement block. The second bolt is inserted into one side of the placement block and reaches into the placement groove on one side of the placement block. The limiting plate is located inside the placement groove on one side of the placement block and is connected to the second bolt on one side.
[0008] The aforementioned components achieve the following effect: When testing samples from multiple test bottles, the second bolt can be rotated first, causing it to rotate within the threaded part of the placement block. Then, one side of the second bolt rotates on the surface of the limiting plate, moving the limiting plate within the placement slot of the placement block to adjust the size of the slot. This allows the placement slot on one side of the placement block to accommodate test bottles of different sizes. Multiple test bottles are then placed into the placement slot on the surface of the placement block for positioning. The placement block is then rotated, causing it to rotate on the surface of the round rod fixed to one side of the support. The test bottles fixed within the placement slot on one side of the placement block then reach the lower end of the burette. Finally, the first bolt is rotated, fixing it to one side of the round rod. The internal thread of the fixing block rotates to make the first bolt abut against the placement block, thus fixing the position of the placement block. Then, when testing the samples inside the subsequent test bottles, the placement block is continuously rotated, and the first bolt is continuously abutted against and fixed to the placement block. This allows multiple test bottles to be sequentially moved to the lower end of the burette for titration testing. By using a limit adjustment device, multiple test bottles can be limited and fixed at the upper end of the support. Then, multiple test bottles are sequentially moved to the burette for titration testing. This avoids the need to constantly fix and replace the test bottles when conducting environmental protection testing on multiple test bottles, which would lead to a lot of operation steps, thereby improving the efficiency of the titration device.
[0009] Preferably, the two ends of the limiting plate are close to each other, and the limiting plate is U-shaped.
[0010] The effect achieved by the above components is that by bringing the two ends of the limiting plate closer together and forming a U-shape, the limiting plate can make better contact with the detection bottle, thereby improving the effectiveness of the limiting plate.
[0011] Preferably, a stabilizing component is provided on one side of the limiting plate to improve the stability of the moving limit plate.
[0012] Preferably, the stabilizing component includes a stabilizing plate and a sliding groove formed inside a placement groove on one side of the placement block. One side of the stabilizing plate is fixed to a limiting plate, and the other side moves in the sliding groove inside the placement groove on one side of the placement block.
[0013] The effect achieved by the above components is as follows: by fixing one side of the stabilizing plate to the limiting plate, and by sliding the other side of the stabilizing plate in the groove inside the placement slot on one side of the placement block, the movement trajectory of the limiting plate is restricted, so that the limiting plate can move more stably.
[0014] Preferably, an anti-slip block is provided on one side of the second bolt to increase the friction on that side of the second bolt.
[0015] The effect achieved by the above components is that by fixing several anti-slip blocks on one side of the second bolt, the friction on one side of the second bolt is increased, making the second bolt easier to rotate.
[0016] Preferably, an inclined groove is formed at the upper end of the placement groove on one side of the placement block to increase the inlet size of the placement groove on one side of the placement block.
[0017] The effect achieved by the above components is that by opening an inclined groove at the upper end of the placement groove on one side of the placement block, the size of the entrance of the placement groove on one side of the placement block is increased, making it easier for the test bottle to reach the inside of the placement groove on one side of the placement block.
[0018] Preferably, the placement block is provided with a rubber pad on the side near the first bolt to increase the friction between the placement block and the first bolt.
[0019] The effect achieved by the above-mentioned components is to increase the friction between the first bolt and the placement block by fixing the rubber pad on the side of the placement block near the first bolt, thereby making the first bolt better abut and fix to the placement block.
[0020] In summary, the beneficial effects of this utility model are as follows:
[0021] By using a limit adjustment device, multiple test bottles can be fixed at the upper end of the bracket, and then the multiple test bottles can be moved to the burette for titration testing in sequence. This avoids the need to constantly fix and replace the test bottles when conducting environmental protection testing on multiple samples inside the test bottles, which would result in a lot of operation steps, thereby improving the efficiency of the titration device.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0030] Figures 1 to 4 The illustrated titration apparatus for environmental testing includes a support 1, a burette 2 on one side of the support 1, and a limiting adjustment device 3 on another side of the support 1. The limiting adjustment device 3, via a placement block 34, limits and adjusts the position of the test bottles. During environmental testing, the burette 2 on the support 1 titrates the reagent inside into the test bottle. The sample inside the test bottle then reacts to detect harmful substances. The burette 2 is equipped with multiple electrodes to monitor changes in the sample in real time, helping to determine the reaction endpoint and automatically stop the titration. When conducting environmental testing on multiple test bottles, the limiting adjustment device 3 can fix multiple test bottles at the upper end of the support 1, and then the multiple test bottles are moved sequentially to the burette 2 for titration.
[0031] Figures 1 to 4The limit adjustment device 3 shown includes a round rod 31, a fixing block 32, a first bolt 33, a placement block 34, a second bolt 36, and a limit plate 37. The round rod 31 is located at the upper end of the bracket 1, the fixing block 32 is located at the upper end of the round rod 31, the first bolt 33 is inserted into one side of the fixing block 32, the placement block 34 rotates on the surface of the round rod 31, and a plurality of placement grooves 35 are opened on the circumference of the surface of the placement block 34. The second bolt 36 is inserted into one side of the placement block 34 and reaches into the placement groove 35 on one side of the placement block 34. The limit plate 37 is located inside the placement groove 35 on one side of the placement block 34 and is connected to the second bolt 36 on one side.
[0032] Figures 1 to 4 As shown, when testing samples inside multiple test bottles, the second bolt 36 can be rotated first, causing it to rotate within the thread of the placement block 34. Then, one side of the second bolt 36 rotates on the surface of the limiting plate 37, causing the limiting plate 37 to move within the placement groove 35 of the placement block 34. This adjusts the size of the placement groove 35, allowing it to accommodate test bottles of different sizes. Multiple test bottles are then placed into the placement groove 35 on the surface of the placement block 34 for positioning. The placement block 34 is then rotated, causing it to rotate on the surface of the round rod 31 fixed to one side of the support 1. The test bottles fixed within the placement groove 35 on one side of the placement block 34 then reach the lower end of the burette 2. Finally, the first bolt 33 is rotated, causing it to rotate within the thread of the placement block 34. The internal thread of the fixing block 32, which is fixed on one side of the round rod 31, rotates to make the first bolt 33 abut against the placement block 34, thus fixing the position of the placement block 34. Then, when testing the samples inside the subsequent test bottles, the placement block 34 is continuously rotated, and the first bolt 33 is continuously abutted against and fixed to the placement block 34, so that multiple test bottles can be sequentially moved to the lower end of the burette 2 for titration testing. By using the limit adjustment device 3, multiple test bottles can be limited and fixed at the upper end of the bracket 1, and then multiple test bottles can be sequentially moved to the burette 2 for titration testing. This avoids the need to constantly fix and replace the test bottles when conducting environmental protection testing on multiple test bottle samples, which would lead to a lot of operation steps, thereby improving the efficiency of the titration device.
[0033] Figures 1 to 4 The two ends of the limiting plate 37 shown are close to each other, and the limiting plate 37 is U-shaped. By bringing the two ends of the limiting plate 37 close to each other and forming a U-shape, the limiting plate 37 can make better contact with the detection bottle, thereby improving the performance of the limiting plate 37.
[0034] Figures 1 to 4A stabilizing component 38 is provided on one side of the limiting plate 37 to improve the stability of its movement. The stabilizing component 38 includes a stabilizing plate 382 and a sliding groove 381 inside the placement groove 35 on one side of the placement block 34. One side of the stabilizing plate 382 is fixed to the limiting plate 37, and the other side moves within the sliding groove 381 inside the placement groove 35 on one side of the placement block 34. By fixing one side of the stabilizing plate 382 to the limiting plate 37 and sliding the other side of the stabilizing plate 382 within the sliding groove 381 inside the placement groove 35 on one side of the placement block 34, the movement trajectory of the limiting plate 37 is restricted, making the limiting plate 37 move more stably.
[0035] Figures 1 to 4 The second bolt 36 shown has a slider 39 on one side to increase the friction on that side. By fixing several sliders 39 to one side of the second bolt 36, the friction on that side is increased, making the second bolt 36 easier to rotate.
[0036] Figures 1 to 4 A sloping groove 310 is formed at the upper end of the placement groove 35 on one side of the placement block 34 to increase the inlet size of the placement groove 35 on one side of the placement block 34. By forming a sloping groove 310 at the upper end of the placement groove 35 on one side of the placement block 34, the inlet size of the placement groove 35 on one side of the placement block 34 is increased, making it easier for the test bottle to reach the interior of the placement groove 35 on one side of the placement block 34. A rubber pad 311 is provided on the side of the placement block 34 near the first bolt 33 to increase the friction between the placement block 34 and the first bolt 33. By fixing the rubber pad 311 to the side of the placement block 34 near the first bolt 33, the friction between the first bolt 33 and the placement block 34 is increased, thus allowing the first bolt 33 to better abut and fix itself to the placement block 34.
[0037] Working principle: During environmental testing, the burette 2 on the support 1 titrates the reagent inside into the test bottle. The sample inside the test bottle then reacts to detect harmful substances in the sample. The burette 2 is equipped with multiple electrodes to monitor the changes in the sample in real time, help determine the reaction endpoint, and automatically stop the dripping. When conducting environmental testing on multiple test bottles, the limit adjustment device 3 can limit and fix multiple test bottles at the upper end of the support 1, and then move the multiple test bottles to the burette 2 in sequence for titration testing. When testing samples inside multiple test bottles, the second bolt 36 can be rotated first, causing it to rotate within the thread of the placement block 34. Then, one side of the second bolt 36 rotates on the surface of the limiting plate 37, moving the limiting plate 37 within the placement groove 35 of the placement block 34 to adjust the size of the placement groove 35. This allows the placement groove 35 on one side of the placement block 34 to accommodate test bottles of different sizes. Multiple test bottles are then placed into the placement groove 35 on the surface of the placement block 34 for positioning. The placement block 34 is then rotated, causing it to rotate on the surface of the round rod 31 fixed to one side of the support 1. The test bottles fixed within the placement groove 35 on one side of the placement block 34 then reach the lower end of the burette 2. Finally, the first bolt 33 is rotated, causing it to rotate within the circular rod 31 fixed to one side of the support 1. The internal thread of the fixing block 32 fixed on one side of the rod 31 rotates to make the first bolt 33 abut against the placement block 34, thus fixing the position of the placement block 34. Then, when testing the samples inside the subsequent test bottles, the placement block 34 is continuously rotated, and the first bolt 33 is continuously abutted against and fixed to the placement block 34, so that multiple test bottles can be moved to the lower end of the burette 2 for titration testing in sequence. By using the limit adjustment device 3, multiple test bottles can be limited and fixed at the upper end of the bracket 1, and then multiple test bottles can be moved to the burette 2 for titration testing in sequence. This avoids the need to constantly fix and replace the test bottles when conducting environmental protection testing on multiple test bottle samples, which would lead to a lot of operation steps, thereby improving the efficiency of the titration device.
