[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 5As shown, a titration apparatus for producing aluminum hydroxide adjuvant according to an embodiment of the present invention includes a base 1; a rotating seat 11 is rotatably connected to the top of the base 1; a placement groove 16 is provided in the middle of the rotating seat 11; a titration cup 17 is installed in the middle of the placement groove 16; a support rod 12 is rotatably connected to the middle of the base 1; the support rod 12 passes through the middle of the rotating seat 11; a fixing ring 13 is fixedly connected to the middle of the support rod 12; the fixing ring 13 is fixedly connected to the top of the support rod 12; an elastic clamping plate 14 is fixedly connected to the middle of the fixing ring 13; a burette 15 is installed in the middle of the elastic clamping plate 14; a quantitative component 4 is provided in the middle of the burette 15; a stirring component 3 is installed in the middle of the support rod 12; a stirring rod 18 is installed in the middle of the stirring component 3; and a fixed component 17 is installed in the middle of the rotating seat 11. Fixed component 2; titration cup 17 is located in the middle of fixed component 2; a fastening screw 19 is installed in the middle of base 1; fixed component 2 includes a fixed rod 21; fixed rod 21 is fixedly connected to the middle of rotating seat 11; two positioning plates 22 are fixedly connected to the side wall of fixed rod 21; the two positioning plates 22 are arranged opposite each other; multiple sets of support plates 23 are hinged to the inner side wall of positioning plate 22; each set consists of two support plates 23; torsion springs 24 are installed at the ends of the two support plates 23; flexible plates 25 are rotatably connected to the ends of support plates 23; during operation, a certain amount of aluminum hydroxide sample is placed in titration cup 17, an excess of hydrochloric acid standard solution of known concentration is added to titration cup 17, titration cup 17 is placed in the placement slot 16, and fixed component 2 is used to... The stirring assembly 3 is fixed in place to completely dissolve the aluminum hydroxide. After stirring, the fastening screw 19 is rotated to rotate the rotating seat 11, moving the placement slot 16 to the corresponding position of the burette 15. The rotating seat 11 is then fixed, and the solution is titrated through the burette 15. When titrating with different sized titration cups 17, the titration cup 17 is placed between two positioning plates 22, and the positioning plates 22 are squeezed. Through elastic setting, the ends of the positioning plates 22 are continuously opened, and multiple sets of flexible plates 25 are in contact with the surface of the titration cup 17. The flexible plates 25 are pressed according to the shape of the titration cup 17. At this time, the two support plates 23 rotate when squeezed. The torsion spring 24 absorbs the rotational energy of the two support plates 23. The flexible plate 25 clamps and fixes the titration cup 17. When the titration cup 17 is removed, it is reset by the torsion spring 24, so that the titration cup 17 remains stable during stirring and titration.

It is compatible with titration cups 17 of various sizes and can automatically adjust the clamping force according to the outer diameter of the beaker. Even if the beaker size is different, it can be tightly fixed. The fixed position of the titration cup 17 is relatively stable, which facilitates the precise positioning of the burette 15, reduces the displacement of the titration cup 17 during stirring and titration, reduces titration error, and reduces the risk of solution spillage or the tip of the titration cup 17 colliding with the inner wall of the titration cup 17 due to movement, thus increasing the safety of operation.

[0020] like Figure 1 and Figure 3As shown, the stirring assembly 3 includes a threaded cylinder 31; the threaded cylinder 31 is fixedly connected to the middle of the support rod 12; the threaded cylinder 31 is fixedly connected to the bottom of the fixing ring 13; a rotating handle 33 is fixedly connected to the end of the threaded cylinder 31; the rotating handle 33 is rotatably connected to the middle of the support rod 12; a nut 32 is installed in the middle of the threaded cylinder 31; a fixing plate 34 is fixedly connected to the middle of the nut 32; a driver 35 is installed on the top of the fixing plate 34; the output end of the driver 35 passes through the middle of the fixing plate 34; the output end of the driver 35... A fixing block 36 is fixedly connected; the bottom of the fixing block 36 has an installation groove 37 and a first sliding groove 39; an installation block 38 is installed in the middle of the installation groove 37; the end of the stirring rod 18 is fixedly connected to the middle of the installation block 38; two first sliding rods 301 are slidably connected in the middle of the first sliding groove 39; a retaining plate 302 is fixedly connected to the ends of the two first sliding rods 301; a through groove 303 is opened in the middle of the retaining plate 302; when the stirring rod 18 is installed, the through groove 303 coincides with the installation groove 37, and the stirring rod 18 is then installed. The mounting block 38 enters the mounting groove 37 through the through groove 303. Then, the clamping plate 302 is rotated to make the first sliding rod 301 slide in the middle of the first sliding groove 39. At this time, the through groove 303 and the mounting groove 37 are perpendicular. When the titration cup 17 is placed in the placement groove 16, the rotating handle 33 is rotated to make the threaded cylinder 31 rotate in the middle of the support rod 12. At this time, the nut 32 moves downward. The nut 32 has a limit rod in the middle. At the same time, the driver 35 is turned on, and the driver 35 drives the fixing block 36 to rotate. As the fixing block 36 rotates, the stirring rod 18 quickly stirs the liquid inside the titration cup 17. Through the above structure, the stirring rod 18 can be adjusted up and down to adjust the depth of insertion into the liquid, flexibly adjust the stirring position, so that different liquid levels can be fully mixed, reduce uneven stirring that leads to incomplete reaction or uneven concentration, and can quickly disassemble the stirring rod 18 for timely disassembly and cleaning to reduce cross-contamination and improve the accuracy of subsequent experiments.

[0021] like Figure 1 and Figure 4As shown, the quantitative assembly 4 includes a rotating ring 41; the rotating ring 41 is rotatably connected to the middle of the burette 15; a first quantitative plate 42 is fixedly connected to the middle of the rotating ring 41; multiple plugs 43 are fixedly connected to the middle of the first quantitative plate 42; a second quantitative plate 44 is fixedly connected to the middle of the burette 15; multiple through holes 47 are opened in the middle of the second quantitative plate 44; a second groove 45 is opened at the bottom of the second quantitative plate 44; a second slide rod 46 is slidably connected to the middle of the second groove 45; the end of the second slide rod 46 is fixedly connected to the top of the first quantitative plate 42; during operation, during the titration process through the burette 15, rotating the rotating ring 41 causes the bottom of the burette 15 to move with the burette 15. As the rotating ring 41 rotates, the second sliding rod 46 rotates from one end of the second sliding groove 45 to the other end. When multiple blocking blocks 43 coincide with multiple through holes 47, the liquid discharge speed decreases. When the first metering plate 42 is rotated again, the blocking block 43 moves between two through holes 47, thereby exposing all the through holes 47 and increasing the liquid discharge speed. The liquid outflow speed can be controlled according to actual needs. With the above structure, in the initial stage of titration, the flow rate can be increased to quickly add the titrant and shorten the experimental time. When approaching the endpoint, the flow rate can be reduced to reduce the amount of titrant exceeding the endpoint due to excessively fast titration, thus reducing titration error.

[0022] like Figure 5 As shown, a liquid storage chamber 5 is provided in the middle of the rotating seat 11; the liquid storage chamber 5 is located at the bottom of the placement groove 16; a heat-conducting plate 51 is fixedly connected to the top of the liquid storage chamber 5; an inlet pipe 52 is fixedly connected to the side wall of the liquid storage chamber 5; the inlet pipe 52 passes through the middle of the rotating seat 11; during operation, hot or cold water is injected into the liquid storage chamber 5 through the end of the inlet pipe 52, and the heat in the water is transferred to the bottom of the titration cup 17 through the heat-conducting plate 51, thereby heating the titration cup 17. When cold water is injected into the liquid storage chamber 5, the heat-conducting plate 51 transfers the heat inside the titration cup 17 to the cooling water, thereby controlling the temperature of the liquid inside the titration cup 17. Through the above structure, the reaction temperature can be adjusted according to the actual needs of the experiment, the dissolution rate of aluminum hydroxide can be increased, and the low measurement results caused by incomplete dissolution can be reduced.

[0023] like Figure 5 As shown, multiple suction cups 6 are fixed to the bottom of the base 1; the multiple suction cups 6 are set at the edge of the base 1; during operation, when titrating, the base 1 is placed in the designated position, the suction cups 6 adhere to the table and the base 1 is adsorbed onto the table. Through the above structure, the base 1 can be stably placed on the plane, reducing movement and shaking during titration and improving the accuracy of titration.

[0024] like Figure 1 As shown, an anti-slip pad 7 is fixedly attached to the middle of the rotating handle 33; the anti-slip pad 7 is fixedly attached to the outer wall of the rotating handle 33; when working, when rotating the rotating handle 33, the soft material of the anti-slip pad 7 will fit against the hand, and the above structure increases the friction between the hand and the rotating handle 33, thereby increasing the comfort of the hand.

[0025] During operation, a certain amount of aluminum hydroxide sample is placed in the titration cup 17. An excess of hydrochloric acid standard solution of known concentration is added to the titration cup 17. The titration cup 17 is placed in the placement tank 16 and fixed in place by the fixing component 2. The stirring component 3 is controlled to stir until the aluminum hydroxide is completely dissolved. After stirring, the fastening screw 19 is rotated to rotate the rotating seat 11, moving the placement tank 16 to the corresponding position of the burette 15. The rotating seat 11 is then fixed, and the solution is titrated through the burette 15. When titrating with titration cups 17 of different sizes, the titration cup 17 is placed between two positioning plates 22, and the positioning plates 22 are pressed. The elastic setting keeps the ends of the positioning plates 22 continuously open. Multiple sets of flexible plates 25 are in contact with the surface of the titration cup 17. Pressure is applied to the flexible plates 25 according to the shape of the titration cup 17. When the two support plates 23 are compressed, they rotate. The torsion spring 24 absorbs the rotational energy of the two support plates 23. The multiple sets of flexible plates 25 clamp and fix the titration cup 17 in place. When the titration cup 17 is removed, it is reset by the torsion spring 24, ensuring the titration cup 17 remains stable during stirring and titration. When installing the stirring rod 18, the through groove 303 coincides with the mounting groove 37. The mounting block 38 is inserted into the mounting groove 37 through the through groove 303. Then, the clamping plate 302 is rotated to make the first sliding rod 301 slide in the middle of the first sliding groove 39. At this time, the through groove 303 and the mounting groove 37 are perpendicular. When the titration cup 17 is placed in the placement slot 16, the rotating handle 33 is turned to rotate the threaded cylinder 31 in the middle of the support rod 12. At this time, the nut 32 moves downward. The nut 32 has a limit rod in the middle. At the same time, the driver 35 is turned on, and the driver 35 drives the fixed block 36 to rotate. As the fixed block 36 rotates, the stirring rod 18 quickly stirs the liquid inside the titration cup 17. During the titration process through the burette 15, the rotating ring 41 is rotated to make the bottom of the burette 15 rotate with the rotating ring 41. The second slide rod 46 rotates from one end of the second slide groove 45 to the other end. When multiple block blocks 43 coincide with multiple through holes 47, the liquid discharge speed decreases. When the first metering plate 42 is rotated again, the block blocks 43... 3. Move between the two through holes 47, so that all the through holes 47 are exposed, and the liquid discharge speed increases. Control the liquid flow rate according to actual needs. Inject hot or cold water into the liquid storage chamber 5 through the end of the liquid inlet pipe 52. The heat in the water is transferred to the bottom of the titration cup 17 through the heat conduction plate 51, thereby heating the titration cup 17. When cold water is injected into the liquid storage chamber 5, the heat conduction plate 51 transfers the heat inside the titration cup 17 to the cooling water, thereby controlling the temperature of the liquid inside the titration cup 17. When titrating, place the base 1 in the designated position, and the suction cup 6 attaches to the table and adsorbs the base 1 onto the table. When rotating the handle 33, the soft material of the anti-slip pad 7 will make it fit against the hand.
