Description

Technical Field

[0001] This invention relates to the field of chemical testing technology, and in particular to an impurity analysis instrument for chemical testing. Background Technology

[0002] Chemical impurities refer to foreign substances that are unintentionally added but unavoidable during the production, processing, storage and transportation of chemical products, and that affect the quality or performance of the products.

[0003] A search of Chinese patent publication number CN113138112A reveals a chemical impurity analyzer, relating to the field of chemical testing technology. Specifically, the analyzer includes an analyzer housing with supporting feet fixed to its lower part; a display screen embedded in the outer wall of the housing; a feed pipe positioned above the housing, with a quantitative tank connected above the feed pipe, the feed pipe and the quantitative tank communicating with each other; a metal detector fixed to the outer wall of the feed pipe; and the analyzer itself. This chemical impurity analyzer features a quantitative tank. By opening the protective cover, industrial impurities are added to the quantitative tank. The scale allows for convenient observation of the impurities within the tank. After adding an appropriate amount, the protective cover is closed, thus achieving quantitative measurement and preventing the addition of excessive industrial impurities that could hinder accurate data acquisition. This method is highly practical.

[0004] However, the above invention has the following shortcomings:

[0005] Although the above-mentioned device can achieve the effect of quantitative detection of chemical impurities, during the detection process, since impurities are generally located inside the solution, some impurities are insoluble and some are soluble. This results in impurities not being evenly distributed inside the solution. In addition, in the above-mentioned technology, the analytical probe is only set on one side inside the analytical chamber, which means that the analytical probe cannot make even contact with the impurities during the analysis, thus leading to inaccurate detection results. Summary of the Invention

[0006] The purpose of this invention is to provide an impurity analysis instrument for chemical testing, so as to solve the problems mentioned in the background art.

[0009] Preferably, a mounting base is fixedly installed inside the machine body at the position corresponding to the metal collection box, the metal collection box is movably mounted on the mounting base, and a sieve plate is obliquely arranged inside the metal collection box.

[0010] Preferably, a solution collection tank is movably installed inside the lower part of the machine body, and a solution collection pipe is fixedly installed inside the machine body at the positions corresponding to the metal collection tank and the solution collection tank, respectively communicating with the interior of the metal collection tank and the solution collection tank.

[0011] Preferably, a feeding valve is fixedly installed on the feeding pipe, a check valve is installed on the feeding pipe, and an air pump is fixedly installed inside the machine body at the position corresponding to the feeding pipe. Air pipes are fixedly installed on both the output and input ends of the air pump, and one of the air pipes is connected to the feeding pipe.

[0012] Preferably, a movable chamber is movably installed at the bottom of the feed pipe, a drain pipe is fixedly installed on one side of the bottom of the movable chamber, and an opening is provided at the top of the solution collection tank corresponding to the position of the drain pipe.

[0013] Preferably, a water storage tank is fixedly installed on the machine body, a water pump is installed inside the water storage tank, a water delivery pipe is fixedly installed on the output end of the water pump, and the other end of the water delivery pipe is connected to the feed pipe.

[0014] Preferably, a wastewater tank is provided inside the lower part of the machine body, and an opening is also provided on the wastewater tank. A drain pipe is fixedly installed on the lower side wall of the wastewater tank, and a steering mechanism is provided inside the machine body.

[0015] Preferably, the steering mechanism includes a transmission gear ring, a second motor, a rotating shaft, a drive gear, and a limiting seat. The transmission gear ring is fixedly sleeved on the side wall of the movable compartment. The second motor is fixedly installed on the top of the wastewater tank. The rotating shaft is fixedly installed on the output end of the second motor. The drive gear is fixedly installed on the top of the rotating shaft, and the drive gear meshes with the transmission gear ring. The limiting seat is fixedly installed inside the machine body, and the drain pipe is located inside the limiting seat.

[0016] Preferably, the top of the feeding box is provided with a cover plate, and a fixed seat is fixedly installed on the upper side wall of the feeding box. A third torsion spring shaft is movably installed inside the fixed seat. An installation block is fixedly sleeved on the third torsion spring shaft. The installation block is fixedly connected to the cover plate. The cover plate is movably installed on the top of the feeding box through the fixed seat, the third torsion spring shaft and the installation block.

[0017] This invention provides an improved impurity analysis instrument for chemical testing, which has the following improvements and advantages compared with the prior art:

[0018] Firstly, in this invention, once the solution falls into the mixing chamber, the first motor is activated. The first motor drives the stirring blades to rotate via the stirring rod. The rotation of the stirring blades stirs the solution, allowing impurities in the solution to be evenly distributed within the solution. Once the solution inside the mixing chamber is evenly mixed, it is fed into the feed pipe. As the solution flows through the feed pipe, the detector analyzes the impurities in the solution flowing through the feed pipe using its detection head. The analysis results are then displayed on the screen, achieving the effect of evenly distributing impurities within the solution and thus ensuring the accuracy of the detection results.

[0019] Secondly, this invention, through the setting of the collection mechanism, ensures that after all the solution inside the mixing chamber flows into the discharge pipe, the metal product remains inside the mixing chamber. Since the first motor is a forward and reverse motor, when the first motor drives the stirring rod to rotate clockwise inside the mixing chamber, the stirring blade can squeeze the clamping block, causing the clamping block to retract into the movable groove. At this time, the sealing plate will not move. When it is necessary to collect the metal product, the first motor can be made to rotate the stirring blade counterclockwise inside the mixing chamber. When the stirring blade rotates counterclockwise, the contact between the stirring blade and the clamping block will prevent the clamping block from retracting into the movable groove. At this time, the sealing plate will be subjected to the squeezing force and flip inside the discharge port. The metal product inside the mixing chamber can then fall into the metal collection box through the discharge port and be collected, thereby achieving the effect of automatically collecting the metal product.

[0020] Thirdly, in this invention, after the solution is fed and tested, the air pump can be started. The air pump can inject air into the inside of the feed pipe through the air pipe. After the air enters the inside of the mixing chamber, it will increase the pressure inside the mixing chamber, thereby allowing the solution to completely enter or leave the inside of the feed pipe, achieving the effect of complete feeding.

[0021] Fourthly, this invention incorporates a steering mechanism. When the solution is discharged, the drain pipe is positioned at the opening of the solution collection tank. During cleaning, a second motor is activated. The second motor drives the drive gear to rotate via a rotating shaft. The two drive gears mesh with the transmission gear ring, causing the movable chamber to move the drain pipe. After the drain pipe moves to the other end inside the limiting seat, it is positioned at the opening of the wastewater tank. At this point, the cleaned wastewater discharged from the discharge pipe can be collected by the wastewater tank. This achieves the effect of facilitating the cleaning of the mixing chamber and the discharge pipe while also facilitating the collection of wastewater. Attached Figure Description

[0030] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides an improved impurity analysis instrument for chemical testing. The technical solution of this invention is as follows:

[0032] like Figures 1 to 5As shown in the figure, this embodiment of the invention provides a chemical impurity analysis instrument, including a body 1, which is a hollow structure. A feed box 2 is fixedly installed on the top of the body 1. The feed box 2 is used to add chemical impurities into the interior of the body 1. The chemical impurities mainly include: inorganic impurities, including various metal ions (such as iron, copper, lead, etc.), non-metallic elements (such as sulfur, phosphorus, etc.), and inorganic salts; organic impurities, including unreacted raw materials, by-products, intermediates, and degradation products, which often have similar chemical structures to the target product; solvent residues, solvents used in the synthesis or separation process, such as methanol, ethanol, dichloromethane, etc., which, if not completely removed, will become impurities in the product; catalyst residues, catalysts used to promote the reaction and their by-products, such as acid-base catalysts, metal catalysts, etc.; and microbial contamination, which may exist in some chemical products, especially biological agents. Microorganisms such as bacteria and fungi; residual monomers, monomer molecules that have not been fully polymerized in polymer production; residual additives, including stabilizers, plasticizers, antioxidants, etc., which, although they help improve product performance, can also become impurities if excessive or inappropriate; degradation products, new substances produced by chemical changes caused by factors such as light, heat, and moisture during product storage or handling. Among these, chemical impurities that are soluble in solution include unreacted raw materials, by-products, solvent residues (such as methanol, ethanol, dichloromethane, etc.), and possible biological metabolites and degradation products, while chemical impurities that are insoluble in solution include inorganic insoluble substances such as sand, dust, rust, certain inorganic salt precipitates (such as barium sulfate BaSO4, calcium carbonate CaCO3, etc.), metal oxides, and organic insoluble substances such as some high molecular weight polymers, biomass residues, undissolved cellulose, resin particles, etc.

[0033] The machine body 1 houses a mixing chamber 3, which is a hollow cylindrical structure. A feed pipe 4 is fixedly connected between the discharge box 2 and the mixing chamber 3, connecting the interior of the discharge box 2 and the mixing chamber 3. The solution containing impurities to be tested is added through the discharge box 2, and the solution flows into the mixing chamber 3 through the feed pipe 4. A first motor 5 is fixedly mounted on the machine body 1. The first motor 5 is a forward and reverse motor, and a stirring rod 6 is fixedly mounted on the output end of the first motor 5. The stirring rod 6 is a cylindrical structure located inside the mixing chamber 3. A stirring blade 7 is fixedly mounted on the stirring rod 6. The stirring blade 7 is a rectangular plate with numerous small holes. After the solution falls into the mixing chamber 3, the first motor 5 is activated. The first motor 5 drives the stirring blade 7 to rotate via the stirring rod 6. The rotation of the stirring blade 7 stirs the solution, ensuring that the impurities in the solution are evenly distributed. Inside the solution, a feed pipe 8 is fixedly installed below the mixing chamber 3, and the feed pipe 8 is connected to the interior of the mixing chamber 3. Multiple detectors 9 are fixedly installed inside the machine body 1 at the position corresponding to the feed pipe 8. A detection head 10 is fixedly installed on the input end of the detector 9, and the detection head 10 is located inside the feed pipe 8. A display screen 40 is fixedly installed on the outer wall of the machine body 1, and the display screen 40 is electrically connected to the detectors 9. When the solution inside the mixing chamber 3 is mixed evenly, the solution can be sent into the interior of the feed pipe 8. When the solution flows inside the feed pipe 8, the detectors 9 can perform impurity analysis on the solution flowing inside the feed pipe 8 through the detection head 10, and the analysis results can be displayed on the display screen 40. A filter screen 18 is fixedly installed above the interior of the feed pipe 8. The filter screen 18 can filter out the metal products inside the solution to avoid the metal products affecting the detection. A collection mechanism is provided on the machine body 1 and the mixing chamber 3.

[0034] The collection mechanism includes a metal collection box 11, a sealing plate 13, a first torsion spring shaft 14, a second torsion spring shaft 16, and a locking block 17. The metal collection box 11 is a hollow rectangular structure and is movably installed inside the machine body 1. A discharge port 12 is provided on one side of the mixing chamber 3. The discharge port 12 is an arc-shaped groove. The sealing plate 13 is an arc-shaped plate with the same size as the inside of the discharge port 12 and is movably installed inside the discharge port 12. The first torsion spring shaft 14 is movably installed above the inside of the discharge port 12. The sealing plate 13 is fixedly sleeved on the first torsion spring shaft 14. The sealing plate 13 is movably installed inside the discharge port 12 through the first torsion spring shaft 14 and seals the discharge port 12. A movable groove 15 is provided on the sealing plate 13. The movable groove 15 is a triangular groove. The second torsion spring shaft 16 is movably installed inside the movable groove 15. The locking block 17 is a triangular block and is fixedly sleeved on the second torsion spring shaft 16. The mechanism is designed so that after all the solution inside the mixing chamber 3 flows into the discharge pipe 8, the metal product will remain inside the mixing chamber 3. Since the first motor 5 is a forward and reverse motor, when the first motor 5 drives the stirring rod 6 to rotate the stirring blade 7 clockwise inside the mixing chamber 3, the stirring blade 7 can squeeze the clamping block 17, and the clamping block 17 can retract into the movable groove 15. At this time, the sealing plate 13 will not move. When it is necessary to collect the metal product, the first motor 5 can drive the stirring blade 7 to rotate counterclockwise inside the mixing chamber 3. When the stirring blade 7 rotates counterclockwise, the contact between the stirring blade 7 and the clamping block 17 will prevent the clamping block 17 from retracting into the movable groove 15. At this time, the sealing plate 13 will be squeezed and flipped inside the discharge port 12. The metal product inside the mixing chamber 3 can then fall into the metal collection box 11 through the discharge port 12 and be collected, thereby achieving the effect of automatically collecting the metal product.

[0035] A discharge valve 19 is fixedly installed on the discharge pipe 8, and a check valve 20 is installed on the feed pipe 4. The discharge valve 19 can quantitatively limit the solution passing through the discharge pipe 8. An air pump 21 is fixedly installed inside the machine body 1 at the position corresponding to the feed pipe 4. Air pipes 22 are fixedly installed on both the output and input ends of the air pump 21. One of the air pipes 22 is connected to the feed pipe 4. After the solution is discharged and detected, the air pump 21 can be started. The air pump 21 can inject air into the feed pipe 4 through the air pipe 22. After the air enters the mixing chamber 3, it will increase the pressure inside the mixing chamber 3, thereby allowing the solution to completely enter or leave the discharge pipe 8, achieving the effect of complete discharge.

[0036] An mounting base 23 is fixedly installed inside the machine body 1 at the position corresponding to the metal collection box 11. The mounting base 23 has an "L" shaped structure. The metal collection box 11 is movably installed on the mounting base 23. A sieve plate 24 is obliquely arranged inside the metal collection box 11. The sieve plate 24 can filter the metal products entering the metal collection box 11. A solution collection box 25 is movably installed at the bottom inside the machine body 1. The solution collection box 25 has a hollow rectangular structure. A solution collection pipe 26 is fixedly installed inside the machine body 1 at the positions corresponding to the metal collection box 11 and the solution collection box 25. The solution remaining inside the metal collection box 11 after filtering the metal products can flow through the solution collection pipe 26 into the solution collection box 25 and be collected.

[0037] A movable chamber 27 is movably installed at the bottom of the feed pipe 8. The movable chamber 27 is a hollow cylindrical structure. A drain pipe 28 is fixedly installed on one side of the bottom of the movable chamber 27. The drain pipe 28 is a cylindrical pipe. An opening 29 is opened at the top of the solution collection tank 25 corresponding to the position of the drain pipe 28. The tested solution can flow through the movable chamber 27, the drain pipe 28 and the opening 29 into the interior of the solution collection tank 25 for collection.

[0038] A water storage tank 30 is fixedly installed on the machine body 1. The water storage tank 30 has a hollow rectangular structure and is filled with cleaning water. A water pump 31 is installed inside the water storage tank 30. A water delivery pipe 32 is fixedly installed on the output end of the water pump 31. The water delivery pipe 32 is an "L" shaped pipe. The other end of the water delivery pipe 32 is connected to the feed pipe 4. When the solution detection is completed, the water pump 31 can be started. The water pump 31 can draw water from the water storage tank 30 and send it into the feed pipe 4 through the water delivery pipe 32. Then it flows into the mixing chamber 3, which can clean the interior of the mixing chamber 3 and the discharge pipe 8. A wastewater tank 33 is installed at the bottom of the machine body 1. The wastewater tank 33 has a hollow rectangular structure and an opening 29. A drain pipe 39 is fixedly installed on the lower side wall of the wastewater tank 33. A steering mechanism is installed inside the machine body 1.

[0039] The steering mechanism includes a transmission gear ring 34, a second motor 35, a rotating shaft 36, a drive gear 37, and a limiting seat 38. The transmission gear ring 34 is an annular structure and is fixedly sleeved on the side wall of the movable chamber 27. The second motor 35 is fixedly installed on the top of the wastewater tank 33, and the rotating shaft 36 is fixedly installed on the output end of the second motor 35. The drive gear 37 is fixedly installed on the top of the rotating shaft 36, and the drive gear 37 meshes with the transmission gear ring 34. The limiting seat 38 is a hollow arc-shaped structure and is fixedly installed inside the machine body 1. The drain pipe 28 is located inside the limiting seat 38. By providing the steering mechanism, when the solution is... During discharge, the drain pipe 28 is located at the opening 29 on the solution collection tank 25. When cleaning, the second motor 35 can be started. The second motor 35 drives the drive gear 37 to rotate through the rotating shaft 36. The second drive gear 37 meshes with the transmission gear ring 34, which causes the movable chamber 27 to move the drain pipe 28. After the drain pipe 28 moves to the other end inside the limiting seat 38, it is located at the opening 29 on the wastewater tank 33. At this time, the cleaned wastewater discharged from the discharge pipe 8 can be collected by the wastewater tank 33. Thus, it is convenient to clean the mixing chamber 3 and the discharge pipe 8, and also convenient to collect the wastewater.

[0040] The top of the feeding box 2 is provided with a cover plate 41, which is a circular plate. A fixing seat 42 is fixedly installed on the upper side wall of the feeding box 2. A third torsion spring shaft 43 is movably installed inside the fixing seat 42. The third torsion spring shaft 43 is a cylindrical structure. An mounting block 44 is fixedly sleeved on the third torsion spring shaft 43. The mounting block 44 is fixedly connected to the cover plate 41. The cover plate 41 is movably installed on the top of the feeding box 2 through the fixing seat 42, the third torsion spring shaft 43 and the mounting block 44. When adding solution, the cover plate 41 can be flipped. After adding solution, the cover plate 41 can be reset to seal the inside of the feeding box 2.

[0041] Specific implementation steps: Add the solution containing impurities to be tested through the feeding box 2. The solution flows into the mixing chamber 3 through the feed pipe 4. After the solution falls into the mixing chamber 3, the first motor 5 is started. The first motor 5 drives the stirring blade 7 to rotate through the stirring rod 6. The rotation of the stirring blade 7 can stir the solution, so that the impurities in the solution can be evenly distributed inside the solution. When the solution inside the mixing chamber 3 is evenly mixed, the solution can be sent into the feeding pipe 8. When the solution flows inside the feeding pipe 8, the detector 9 can analyze the impurities in the solution flowing inside the feeding pipe 8 through the detection head 10. The analysis results can be displayed on the display screen 40, which achieves the effect of even distribution of impurities inside the solution, thereby ensuring the accuracy of the test results.

[0042] Simultaneously, through the setting of the collection mechanism, after all the solution inside the mixing chamber 3 flows into the discharge pipe 8, the metal product will remain inside the mixing chamber 3. Since the first motor 5 is a forward and reverse motor, when the first motor 5 drives the stirring rod 6 to rotate the stirring blade 7 clockwise inside the mixing chamber 3, the stirring blade 7 can squeeze the clamping block 17, and the clamping block 17 can retract into the movable groove 15. At this time, the sealing plate 13 will not move. When it is necessary to collect the metal product, the first motor 5 can drive the stirring blade 7 to rotate counterclockwise inside the mixing chamber 3. When the stirring blade 7 rotates counterclockwise, the contact between the stirring blade 7 and the clamping block 17 will prevent the clamping block 17 from retracting into the movable groove 15. At this time, the sealing plate 13 will be subjected to the squeezing force and flip inside the discharge port 12. The metal product inside the mixing chamber 3 can then fall into the metal collection box 11 through the discharge port 12 and be collected, thereby achieving the effect of automatically collecting the metal product.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
