Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of zinc oxide purity detection, and specifically to a zinc oxide purity detection device. Background Technology
[0002] When zinc oxide comes into contact with dilute sulfuric acid, the solid zinc oxide gradually decreases and eventually dissolves in the dilute sulfuric acid solution. At the beginning of the reaction, the solution may be colorless and transparent. As the reaction proceeds, the solution may turn pale blue because zinc ions enter the solution. Zinc ions in solution will exhibit a specific color. Heat is released during the reaction, and this heat change can be measured with instruments.
[0003] However, traditional zinc oxide purity testing relies on laboratory chemical analysis (such as titration and X-ray diffraction), which suffers from problems such as expensive equipment, complex operation, and long processing time. Therefore, those skilled in the art have provided a zinc oxide purity testing device to solve the problems mentioned in the background art. Utility Model Content

[0005] A zinc oxide purity testing device includes a testing chamber. A feed pipe with a sealing cap is connected to one side of the top of the testing chamber and connected to the chamber. A discharge pipe with a solenoid valve is connected to the bottom of the testing chamber. A heat-absorbing mechanism is installed on the inner wall of the testing chamber to absorb the heat generated by the reaction between the zinc oxide sample and the reaction acid solution inside the testing chamber. A mounting frame is installed at the top of the testing chamber, and a testing mechanism for observation is installed on the mounting frame. A stirring mechanism for accelerating the reaction is installed inside the testing chamber.
[0006] Preferably, the heat absorption mechanism includes a heat-conducting shell, and mounting grooves are provided around the inside of the heat-conducting shell. Heat-absorbing tubes are fixedly installed in each of the four mounting grooves. A first connecting pipe is installed between the tops of the four heat-absorbing tubes, and the four heat-absorbing tubes are respectively connected to the periphery of the first connecting pipe.
[0007] Preferably, the detection mechanism includes a second connecting tube, the bottom end of which is connected to the top end of the first connecting tube, a limiting tube is fixedly installed at the bottom inside the second connecting tube, and a corrugated tube is fixedly installed at the top end of the limiting tube.
[0008] Preferably, an air column is installed at the top of the second connecting pipe, and a limiting groove is formed around the top of the second connecting pipe. A limiting block matching the limiting groove is fixedly installed around the air column. The four limiting blocks are movably installed in the four limiting grooves respectively, and the bottom end of the air column is connected to the corrugated pipe.
[0009] Preferably, an observation tube is connected to the top end of the second connecting tube. The observation tube is U-shaped, and a third connecting tube with a solenoid valve is connected to both the top and bottom ends of the middle part of the observation tube.
[0010] Preferably, one end of the observation tube is connected to a dustproof tube, and several through holes are opened around the bottom of the dustproof tube.
[0011] Preferably, the stirring mechanism includes a connecting block, the top of which is fixedly connected to the middle of the bottom of the first connecting pipe, a stirring rod is rotatably mounted on the bottom of the connecting block, a fixing plate is rotatably mounted on the bottom of the stirring rod, the two sides of the fixing plate are respectively fixedly mounted on the two sides of the heat-conducting shell, and a plurality of stirring blades are fixedly mounted on the stirring rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The heat-absorbing and detection mechanisms facilitate the transfer of heat generated by the reaction to the heat-absorbing tube via the heat-conducting shell. This heat causes the gas pressure in the heat-absorbing tube to rise, resulting in gas expansion within the bellows. This gas expansion pushes the gas column towards the observation tube, increasing the gas pressure in the sealed space of the observation tube. This pressure causes the liquid on one side of the observation tube to drop, while the liquid on the other side rises. The height of the rising liquid level can be used to reflect the purity of zinc oxide. The process of detecting zinc oxide is convenient and quick, thus improving the efficiency of zinc oxide purity detection. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described in detail below with reference to embodiments:
[0021] This utility model discloses a zinc oxide purity testing device. (Refer to...) Figure 1-4 The test chamber includes a test chamber 1, a feed pipe 2 with a sealing cap connected to one side of the top of the test chamber 1, a discharge pipe 3 with a solenoid valve connected to the bottom of the test chamber 1, a heat absorption mechanism for absorbing the heat generated by the reaction between the zinc oxide sample and the reaction acid inside the test chamber 1 installed on the inner wall of the test chamber 1, a mounting frame 4 installed at the top of the test chamber 1, a test mechanism for observation installed on the mounting frame 4, and a stirring mechanism for accelerating the reaction installed inside the test chamber 1.
[0022] By adopting the above technical solution, this utility model, through the set heat absorption mechanism and detection mechanism, adds zinc oxide and reaction acid to the detection box 1 through the feed pipe 2. The zinc oxide and reaction acid can react to generate heat. Subsequently, the motor 23 drives the first gear 24 to rotate, which in turn drives the second gear 25 to rotate, thereby driving the stirring rod 20 to rotate. This causes the stirring blade 22 to stir the zinc oxide and reaction acid, improving the reaction efficiency and increasing the heat generated by the reaction. Then, the heat generated by the reaction is transferred to the heat absorption tube 7 through the heat-conducting shell 5. The heat causes the air pressure in the heat absorption tube 7 to rise, which causes the gas in the bellows 11 to expand. The expansion of the gas pushes the gas column 12 towards the observation tube 15, causing the air pressure in the sealed space of the observation tube 15 to rise. This causes the liquid on one side of the observation tube 15 to fall and the liquid on the other side of the observation tube 15 to rise, thus conveniently reflecting the purity of zinc oxide by observing the height of the liquid rise. The process of detecting zinc oxide is convenient and quick, thereby improving the efficiency of detecting the purity of zinc oxide.
[0023] Reference Figure 1-4 The heat absorption mechanism includes a heat-conducting shell 5. The heat-conducting shell 5 has mounting grooves 6 on all four sides. Heat-absorbing tubes 7 are fixedly installed in each of the four mounting grooves 6. A first connecting pipe 8 is installed between the tops of the four heat-absorbing tubes 7, and the four heat-absorbing tubes 7 are respectively connected to the four sides of the first connecting pipe 8.
[0024] By adopting the above technical solution, the four heat absorption tubes 7 can quickly absorb the heat generated by the reaction, thereby improving the heat absorption efficiency and increasing the rising height of the liquid on one side of the observation tube 15, thus facilitating observation.
[0025] Reference Figure 1-4 The testing mechanism includes a second connecting pipe 9, the bottom end of which is connected to the top end of the first connecting pipe 8. A limiting pipe 10 is fixedly installed at the bottom inside the second connecting pipe 9, and a corrugated pipe 11 is fixedly installed at the top end of the limiting pipe 10.
[0026] By adopting the above technical solution, the bellows 11 is provided to store and transfer gas. The expansion and movement of the bellows 11 pushes the gas column 12, thereby increasing the gas pressure between the gas column 12 and the liquid.
[0027] Reference Figure 1-4 An air column 12 is installed at the top of the second connecting pipe 9, and a limiting groove 13 is opened around the top of the second connecting pipe 9. A limiting block 14 matching the limiting groove 13 is fixedly installed around the air column 12. The four limiting blocks 14 are movably installed in the four limiting grooves 13 respectively, and the bottom end of the air column 12 is connected to the corrugated pipe 11.
[0028] By adopting the above technical solution, the stability and accuracy of the air column 12 during movement can be easily ensured by setting the limiting groove 13 and the limiting block 14.
[0029] Reference Figure 1-4 The top end of the second connecting pipe 9 is connected to an observation pipe 15, which is U-shaped. The top and bottom ends of the middle part of the observation pipe 15 are connected to a third connecting pipe 16 with a solenoid valve.
[0030] By adopting the above technical solution, the third connecting pipe 16 facilitates the addition of liquid to the observation tube 15 through the top third connecting pipe 16, and also facilitates the removal of liquid from the observation tube 15 through the bottom third connecting pipe 16, thereby enabling the liquid in the observation tube 15 to be replaced periodically.
[0031] Reference Figure 1-4 One end of the observation tube 15 is connected to a dustproof tube 17, and several through holes 18 are opened around the bottom of the dustproof tube 17.
[0032] By adopting the above technical solution, when testing is performed through the dustproof tube 17 and the through hole 18, the liquid on one side of the observation tube 15 rises, thereby squeezing the gas in the observation tube 15 on that side, allowing the gas to be discharged through the through hole 18. The through hole 18 is located at the bottom of the dustproof tube 17, thereby preventing dust and debris in the air from entering the observation tube 15, thus improving the service life of the liquid in the observation tube 15.
[0033] Reference Figure 1-4 The stirring mechanism includes a connecting block 19. The top of the connecting block 19 is fixedly connected to the middle of the bottom of the first connecting pipe 8. A stirring rod 20 is rotatably installed at the bottom of the connecting block 19. A fixing plate 21 is rotatably installed at the bottom of the stirring rod 20. The two sides of the fixing plate 21 are respectively fixedly installed on the two sides of the heat-conducting shell 5. Several stirring blades 22 are fixedly installed on the stirring rod 20.
[0034] By adopting the above technical solution, the stirring blades 22 can be conveniently driven by the stirring rod 20 to stir the zinc oxide and the reaction acid solution, thereby improving the reaction efficiency and increasing the heat generated by the reaction.
[0035] Reference Figure 1-4 The stirring mechanism also includes a motor 23, which is fixedly installed on the top of the detection box 1. The output shaft of the motor 23 passes through the top of the detection box 1 and is fixedly installed with a first gear 24. The top of the stirring rod 20 is fixedly installed with a second gear 25, and the first gear 24 and the second gear 25 are meshed together.
[0036] By adopting the above technical solution, the first gear 24 and the second gear 25 are set so that the first gear 24 can be driven to rotate by the motor 23, thereby driving the second gear 25 to rotate and thus driving the stirring rod 20 to rotate.
[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
