[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] Refer to Figure 1 and Figure 4, an embodiment provided by the present utility model: an evaporation mechanism for processing ethylene glycol, including a storage barrel 1 and an evaporation barrel 7. The left end of the storage barrel 1 is fixedly connected with a pump body 2, and the left end of the pump body 2 is fixedly connected with a first connecting pipe 3 for preheating the ethylene glycol liquid. The left end of the preheating cylinder 17 is fixedly connected with a steam inlet pipe 16. The left end of the first connecting pipe 3 is fixed with an annular pipe 4. The left end of the annular pipe 4 is fixedly connected with a second connecting pipe 5. The outer wall of the second connecting pipe 5 is fixedly connected to the inner wall of the left end of the preheating cylinder 17. The top end of the preheating cylinder 17 is fixedly connected with a steam outlet pipe 18. The annular pipe 4 is located inside the preheating cylinder 17. The bottom end of the steam inlet pipe 16 is fixedly connected to the top end of the evaporation barrel 7. The bottom end of the second connecting pipe 5 is rotatably connected to the top end of the rotating pipe 6.
[0024] Specifically, the ethylene glycol to be evaporated and purified is stored in the storage barrel 1. The pump body 2 is started, and the ethylene glycol in the storage barrel 1 enters the annular pipe 4 through the first connecting pipe 3. At this time, evaporation has not occurred yet, and there is no steam in the preheating cylinder 17, so preheating cannot be carried out. The ethylene glycol in the annular pipe 4 will enter the rotating pipe 6 through the second connecting pipe 5. Then, the ethylene glycol will be evaporated in the evaporation barrel 7, and the evaporated steam will enter the preheating cylinder 17 through the steam inlet pipe 16. The preheating cylinder 17 will preheat the ethylene glycol that will pass through the annular pipe 4 next, making it easier for the ethylene glycol to be heated during the subsequent evaporation process. Due to its annular shape, the contact area between the ethylene glycol and the steam in the annular pipe 4 becomes larger, making it easier to be preheated. Finally, the steam in the preheating cylinder 17 will go out through the steam outlet pipe 18, making reasonable use of the heat of the steam.
[0025] Refer to Figure 2 and Figure 3 , the top end of the evaporation barrel 7 is fixedly connected with a motor 9 for driving the rotating pipe 6 to rotate to atomize the ethylene glycol liquid. The inner wall of the evaporation barrel 7 is provided with a heating wire 8. The top end of the outer wall of the rotating shaft 10 is rotatably connected to the inner wall of the top end of the evaporation barrel 7. The bottom end of the outer wall of the rotating shaft 10 is fixedly connected with a main gear 11. The outer diameter of the main gear 11 is meshed with a driven gear 12. The outer wall of the rotating pipe 6 is fixedly connected to the inner wall of the driven gear 12. The bottom end of the spray body 13 is fixedly connected with a plurality of small spray nozzles. The outside of the spray body 13 is fixedly connected with a connecting ring 14. The inner wall of the evaporation barrel 7 is fixedly connected with an annular block 15. The outer wall of the connecting ring 14 is rotatably connected to the inner wall of the annular block 15. The front end of the evaporation barrel 7 is fixedly connected with an ethylene glycol discharge pipe 19, and a control valve is installed on the outer wall of the ethylene glycol discharge pipe 19.
[0026] Specifically, start the motor 9 and the heating wire 8. When current passes through the heating wire 8, since the heating wire 8 has a certain resistance, the electrons moving in it will collide with atoms and the lattice, causing electrical energy to be converted into heat energy, thereby increasing the temperature of the heating wire 8 and heating the inside of the evaporation barrel 7. The motor 9 will drive the rotating shaft 10 to rotate, and the rotating shaft 10 will drive the main gear 11 to rotate, thereby driving the driven gear 12 to rotate. The driven gear 12 will drive the rotating tube 6 to rotate. The ethylene glycol in the rotating tube 6 will enter the spray body 13 and be sprayed out in a mist form through multiple small nozzles at the bottom of the spray body 13. When the rotating tube 6 rotates, it drives the spray body 13 to rotate, and the spray body 13 drives the connecting ring 14 to rotate inside the annular block 15. The mist-like ethylene glycol sprayed out during the rotation of the spray body 13 is evenly distributed inside the evaporation barrel 7, making it easier to heat and evaporate the excess water inside. Since the boiling point of ethylene glycol is higher than that of water, when the evaporation operation is carried out and the temperature is controlled near the boiling point of water, the water will first evaporate into water vapor and escape, while the ethylene glycol remains in a liquid state in the evaporation barrel 7. When the evaporation is completed, open the control valve on the ethylene glycol discharge pipe 19 to let out the purified ethylene glycol.
[0027] Working principle: When in use, the ethylene glycol to be purified is stored in the storage barrel 1. Start the pump body 2, and the ethylene glycol in the storage barrel 1 will enter the annular tube 4 through the first connecting pipe 3. At this time, evaporation has not been carried out and there is no vapor in the preheating cylinder 17, so preheating cannot be carried out. The ethylene glycol in the annular tube 4 will enter the rotating tube 6 through the second connecting pipe 5. At this time, start the motor 9 and the heating wire 8 to heat the inside of the evaporation barrel 7. The motor 9 will drive the rotating shaft 10 to rotate, and the rotating shaft 10 will drive the main gear 11 to rotate, thereby driving the driven gear 12 to rotate. The driven gear 12 will drive the rotating tube 6 to rotate. The ethylene glycol in the rotating tube 6 will enter the spray body 13 and be sprayed out in a mist form through multiple small nozzles at the bottom of the spray body 13. When the rotating tube 6 rotates, it drives the spray body 13 to rotate, and the spray body 13 drives the connecting ring 14 to rotate inside the annular block 15. The rotation of the spray body 13 makes the mist-like ethylene glycol sprayed out evenly distributed inside the evaporation barrel 7, making it easier to heat and evaporate the excess water inside. The evaporated vapor will enter the preheating cylinder 17 through the vapor inlet pipe 16. The preheating cylinder 17 will preheat the ethylene glycol passing through the annular tube 4 next, making it easier to be heated during the subsequent evaporation process. Finally, the vapor in the preheating cylinder 17 will go out through the vapor outlet pipe 18. When the evaporation is completed, open the control valve on the ethylene glycol discharge pipe 19 to let out the purified ethylene glycol.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
