Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 - 4. An embodiment of this utility model: An environmentally friendly sulfuric acid colorimetric analyzer includes a support platform 4. A compressor 3 and a condenser 1 are fixedly installed at the bottom of the support platform 4, and the condenser 1 is located behind the compressor 3. A control terminal 12 is fixedly installed on the top left side of the support platform 4. A heating bath 6 and a condensing bath 8 are arranged on the top right side of the support platform 4, and the heating bath 6 is located in front of the condensing bath 8. A hot bath stirring paddle 5 and a hot bath heating rod 7 are installed at the bottom of the heating bath 6, and the hot bath heating rod 7 is located at the side end of the hot bath stirring paddle 5. A cold bath stirring paddle 9 and a cold bath heating rod 10 are installed at the bottom of the condensing bath 8, and the cold bath heating rod 10 is located at the side end of the cold bath stirring paddle 9. A movable bracket 11 is fixedly installed on the top of the support platform 4 near the condensing bath 8. A compressor coil 2 is installed between the compressor 3 and the condenser 1.
[0020] A titration pump 16 is installed inside the control terminal 12. PTFE tubing 15 is fixedly installed on both sides of the titration pump 16. A guide tube 13 is fixedly installed at the end of the PTFE tubing 15 away from the titration pump 16. A glass bottle 14 is slidably fitted onto the outer ring of the guide tube 13. First, the first retaining ring 19 is pulled towards the end away from the second retaining ring 21 until the gap between the first retaining ring 19 and the second retaining ring 21 is greater than the gap at the mouth of the conical flask 17. Then, the neck of the conical flask 17 is suspended between the first retaining ring 19 and the second retaining ring 21. Then, the first retaining ring 19 is released. The elasticity of the positioning spring 18 will cause the first... The rapid reset of the retaining ring 19 allows the first retaining ring 19 to press and secure the conical flask 17 to the second retaining ring 21. Simultaneously, the positioning guide rod 20 slides on both sides inside the second retaining ring 21, supporting the first retaining ring 19 to move linearly, improving the alignment accuracy between the first retaining ring 19 and the second retaining ring 21. Furthermore, plastic gaskets are fixedly installed on the opposing inner surfaces of the first retaining ring 19 and the second retaining ring 21, preventing slippage of the conical flask 17 and avoiding damage to the conical flask 17 by the second retaining ring 21 and the first retaining ring 19. Afterwards, the titration pump 16 can be moved away from the glass bottle 14. The PTFE tube 15 at one end is inserted into the conical flask 17. Then, the PTFE tube 15 at the end of the titration pump 16 furthest from the conical flask 17 is aligned with the guide tube 13 at the center of the top of the glass bottle 14. Subsequently, the bottom end of the movable bracket 11 is rotated and mounted on the support platform 4, allowing the support platform 4 to rotate and adjust the conical flask 17 until it is vertically aligned with the hot bath stirring paddle 5 inside the condensing bath 8 or the heating bath 6. An iron rotor is placed inside the conical flask 17, and magnetic plates are installed on both the hot bath stirring paddle 5 and the cold bath stirring paddle 9. The conical flask 17 is then placed in the heating bath 6 or... When the conical flask 17 is inside the condensing bath 8, its bottom end can contact the magnetic plate on the hot bath stirring paddle 5 or the cold bath stirring paddle 9. This allows the iron rotor inside the conical flask 17 to rotate when the cold bath stirring paddle 9 or the hot bath stirring paddle 5 rotates. At the same time, the titration pump 16 can be started, allowing the sulfuric acid liquid inside the absorbable glass bottle 14 to be discharged into the conical flask 17 through the PTFE tube 15. Furthermore, the titration pump 16 can be adjusted to control the titration speed of the sulfuric acid. Also, because the conical flask 17 is located inside the condensing bath 8 or the heating bath 6, it is convenient to conduct titration experiments within the specified temperature range.
[0021] An extension vertical frame 22 is fixedly installed on the top of the movable support 11. A second retaining ring 21 is fixedly installed at the bottom of the extension vertical frame 22. Positioning guide rods 20 are slidably inserted into both sides of the second retaining ring 21. A first retaining ring 19 is fixedly installed at the front end of the positioning guide rod 20. Positioning springs 18 are symmetrically fixed between the first retaining ring 19 and the second retaining ring 21. A conical bottle 17 is snapped between the first retaining ring 19 and the second retaining ring 21.
[0022] Plastic gaskets are fixedly installed on the inner surfaces of the second retaining ring 21 and the first retaining ring 19 to prevent damage to the conical flask 17.
[0023] The second retaining ring 21 has insertion holes on both sides near the positioning spring 18, which support the first retaining ring 19 to move in a straight line.
[0024] An iron rotor is placed inside the conical flask 17, and magnetic plates are installed on the hot bath stirring paddle 5 and the cold bath stirring paddle 9. When the hot bath stirring paddle 5 or the cold bath stirring paddle 9 rotates, the iron rotor inside the conical flask 17 can be driven to rotate by magnetic attraction, thereby stirring the liquid inside the conical flask 17.
[0025] Working principle: In use, first pull the first retaining ring 19 away from the second retaining ring 21 until the gap between the first retaining ring 19 and the second retaining ring 21 is greater than the gap at the mouth of the conical flask 17. Then, suspend the neck of the conical flask 17 between the first retaining ring 19 and the second retaining ring 21. Then release the first retaining ring 19. The elasticity of the positioning spring 18 will cause the first retaining ring 19 to quickly return to its original position, so that the first retaining ring 19 can press the conical flask 17 and the second retaining ring 21 to secure it. At the same time, the positioning guide rod 20 inside the second retaining ring 21... Lateral sliding allows the first retaining ring 19 to move linearly, improving the accuracy of the engagement between the first retaining ring 19 and the second retaining ring 21. Furthermore, plastic gaskets are fixedly installed on the opposing inner surfaces of the first retaining ring 19 and the second retaining ring 21 to prevent slippage of the conical flask 17 and to avoid damage to the conical flask 17 caused by the second retaining ring 21 and the first retaining ring 19. Subsequently, the PTFE tube 15 at the end of the titration pump 16 away from the glass bottle 14 can be inserted into the conical flask 17, and then the PTFE tube 15 at the end of the titration pump 16 away from the conical flask 17 can be... The conical flask 17 is matched and connected to the guide tube 13 at the center of the top of the glass bottle 14. Then, it is rotatably mounted on the support platform 4 via the bottom end of the movable bracket 11, allowing the support platform 4 to rotate and adjust the conical flask 17 until it is vertically aligned with the hot bath stirring paddle 5 inside the condensing bath 8 or the heating bath 6. Because an iron rotor is placed inside the conical flask 17, and magnetic plates are installed on both the hot bath stirring paddle 5 and the cold bath stirring paddle 9, when the conical flask 17 is placed inside the heating bath 6 or the condensing bath 8, the bottom end of the conical flask 17 can align with the hot bath stirring paddle 5. The magnetic plates on the stirring paddle 5 or the cold bath stirring paddle 9 contact each other, so that when the cold bath stirring paddle 9 or the hot bath stirring paddle 5 rotates, it can drive the iron rotor inside the conical flask 17 to rotate. At the same time, the titration pump 16 can be started, so that the sulfuric acid liquid inside the absorbable glass bottle 14 is discharged into the conical flask 17 through the PTFE tube 15. Furthermore, the titration pump 16 can be adjusted to control the titration speed of sulfuric acid. Meanwhile, because the conical flask 17 is located inside the condensing bath 8 or the heating bath 6, it is convenient to carry out titration experiments in the conical flask 17 within the specified temperature range to complete the work.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
