Description

Technical Field

[0001] This utility model relates to the field of chemical detection technology, specifically a detection device for the production of polyisoprene emulsion. Background Technology

[0002] Polyisoprene is a polymer of isoprene. It is primarily used in tire manufacturing; however, it has a wide range of other applications, including footwear, machinery, pharmaceuticals, sporting goods, latex (such as condoms), latex (such as latex mattresses and pillows), and other industrial products.

[0003] During production, to ensure the purity of polyisoprene, it is necessary to test it. The existing testing method involves placing polyisoprene into a flask and heating the flask to 34 degrees Celsius (the boiling point of polyisoprene) to evaporate it. The residue in the flask is then observed. However, because polyisoprene is toxic, testing too much at once can lead to a large amount of toxic gas in the surrounding environment, which can harm people's health. As a result, the existing testing equipment can only detect a small amount of polyisoprene at a time, which increases the number of tests required and reduces its efficiency. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] See Figures 1-3 In this embodiment of the present invention, a testing device for the production of polyisoprene emulsion includes a housing 1, a testing box 2 fixedly connected to the housing 1, a filling port 18 provided on the front of the testing box 2, a hot air box 7 fixedly connected to the bottom of the testing box 2, heat-conducting fins 8 fixedly connected to the outer wall of the hot air box 7, a detachable heating plate 10 installed on the hot air box 7, an air outlet 11 provided on the outer wall of the testing box 2, and an exhaust pipe 9 fixedly connected between the air outlet 11 and the hot air box 7.

[0021] A partition 21 is fixedly connected inside the housing 1. One side of the partition 21 is a heat chamber, and the other side is a condensation chamber. A main pipe 22 is installed in the condensation chamber. Multiple sets of condensing pipes 23 are fixedly connected to the main pipe 22. A heat-conducting block 24 is fixedly connected to the outer wall of the condensing pipe 23. A collection trough 25 is fixedly connected to the bottom of the condensing pipe 23 and is fixedly connected to the condensation chamber. One end of the collection trough 25 passes through the housing 1 and is fixedly connected to a recovery port 26. An air suction pump 27 is fixedly connected to the outer wall of the housing 1. The air outlet of the air suction pump 27 passes through the housing 1 and is fixedly connected to the main pipe 22. A connecting pipe 28 is fixedly connected to the air inlet of the air suction pump 27. The connecting pipe 28 is connected to the detection box 2.

[0022] A sealing box cover 19 is rotatably connected inside the filling port 18, and a locking pin 20 is installed between the sealing box cover 19 and the detection box 2.

[0023] The heat exchange chamber is equipped with a vortex tube assembly for compressing air and forming hot and cold airflows.

[0024] This invention first injects a polyisoprene emulsion sample into a heating plate 10, then places the heating plate 10 onto a hot air chamber 7. The filling port 18 is then sealed with a sealing cover 19, and the sealing cover 19 is fixed to the filling port 18 using a locking pin 20. Air is then compressed through a vortex tube assembly, forming a hot air stream and a cold air stream. The hot air stream enters the hot air chamber 7 through the hot air outlet 4, and the cold air stream enters the condensation chamber through the cold air outlet 5. At this point, heat is drawn from the air inside the hot air chamber 7 through the heat-conducting fins 8, and then... Gas is used to heat the polyisoprene emulsion on the heating plate 10. Then, the suction pump 27 draws the evaporated isoprene and air from the test chamber 2 through the connecting pipe 28 and pumps them into the main pipe 22. The air is then evenly discharged into the condenser pipe 23. During this process, the isoprene gas in the condenser pipe 23 is condensed by the heat-conducting block 24. The condensed isoprene liquid is discharged into the collection tank 25 along the condenser pipe 23 and then discharged through the recovery port 26. After the test is completed, the quality of the polyisoprene emulsion can be tested by observing the residue on the heating plate 10.

[0025] In one instance of this embodiment, please refer to Figures 1-3 The vortex tube assembly includes a heat distribution tube 3 disposed in the heat distribution chamber. One end of the heat distribution tube 3 is a hot gas outlet 4, and the other end is a cold gas outlet 5. The diameter of the cold gas outlet 5 is smaller than that of the hot gas outlet 4. A heat distribution block 6 is fixedly connected inside the hot gas outlet 4. An outer sleeve 12 is fixedly connected to the outer wall of the heat distribution tube 3. A pressurization chamber 14 is disposed between the outer sleeve 12 and the heat distribution tube 3. An inclined hole 13 is disposed inside the pressurization chamber 14, which connects the pressurization chamber 14 and the inner wall of the heat distribution tube 3. The hot gas outlet 4 passes through the box 1 and is connected to the hot gas box 7. The cold gas outlet 5 passes through the partition 21 and is connected to the condensation chamber. An air inlet hopper 16 is fixedly connected inside the box 1. A compressor 15 is fixedly connected to the air inlet hopper 16. The outlet end of the compressor 15 is connected to the outer sleeve 12, and the inlet end of the compressor 15 is connected to the air inlet hopper 16. A filter screen 17 is installed inside the air inlet end of the air inlet hopper 16.

[0026] The vortex tube assembly first draws in and compresses the air in the intake hopper 16 through the compressor 15. At this time, the filter screen 17 filters the impurities in the air entering the intake hopper 16. Then, the compressed air from the compressor 15 enters the pressurization chamber 14. The high-pressure air then passes through the oblique hole 13 and is injected tangentially into the heat distribution tube 3, thereby forming a vortex in the heat distribution tube 3. At this time, the air temperature at the center of the heat distribution tube 3 is lower, while the air temperature near the inner wall of the heat distribution tube 3 is higher. The hot air with higher temperature enters the hot air box 7 through the hot air outlet 4. Then, the heat in the air in the hot air box 7 is discharged through the heat-conducting fins 8, and the hot air heats the polyisoprene emulsion on the heating plate 10. At the same time, the cold air with lower temperature enters the condensation chamber through the cold air outlet 5.
