Description

Technical Field

[0001] The invention relates to the technical field of antioxidant production equipment, in particular to a phosphite antioxidant deodorizing distillation kettle structure. Background Art

[0002] Phosphite antioxidants are a type of additive widely used in plastics, rubber and other materials. They can effectively inhibit oxidation reactions, extend the service life of materials and maintain stable performance. However, odors are generated during the production process of phosphite antioxidants. The odors can seriously affect the user experience of products using such antioxidants. For example, in plastic or rubber products, obvious odors can make users feel uncomfortable and reduce the market acceptance of products. In addition, odors may mean that there are impurities or unstable components in the antioxidants. Deodorization helps remove these factors that may affect their performance and stability, thereby improving product quality and reliability. At the same time, strong odors do not meet environmental protection requirements, especially in some environments with strict odor control.

[0003] However, when using molecular distillation to separate antioxidants from odorous components by controlling temperature and pressure, a large amount of gas will be generated during the distillation process, which will cause the air pressure inside the distillation kettle to be in an unstable state. When the air pressure increases, the boiling point of the antioxidant will also increase, requiring more heat to reach the boiling point, which will slow down the distillation speed, thereby extending the time required for distillation, increasing energy consumption, and affecting production efficiency and costs. However, when the air pressure decreases, excessive evaporation may occur, which will destroy the originally intended separation effect, making it impossible to effectively separate the antioxidant from the odorous components, resulting in a large amount of odorous components remaining in the antioxidant, affecting product quality, and failing to achieve the intended goal of deodorization.

[0004] Therefore, a phosphite antioxidant deodorizing distillation kettle structure is proposed. Summary of the invention

[0012] Preferably, the interior of the bubble cover is fixedly connected to the limiting rod via a connecting rod, and the interior of the through tube is provided with a movable groove matching the limiting rod, so that the bubble cover will not fall off the through tube.

The condenser 23 is serpentinely wrapped around the inside of the top cover 22, and both ends of the condenser 23 for inlet and outlet of cooling liquid pass through the top cover 22 and extend outward to connect to an external cooling liquid transmission device.

[0040] The liquid accumulation component 24 includes a liquid accumulation bottom plate 241 and a water storage plate 242 slidably connected to the liquid accumulation bottom plate 241. A water storage tank 243 for storing water is provided inside the water storage plate 242. A plurality of bubble caps 245 are provided on the liquid accumulation bottom plate 241, and the bubble caps 245 are evenly distributed on the liquid accumulation bottom plate 241. The bubble caps 245 include a through pipe 2451 fixedly connected to the liquid accumulation bottom plate 241, and a bubble cap cover 2452 is movably connected to the through pipe 2451. A plurality of holes 2453 are provided on the bubble cap cover 2452, and the hole grooves 2453 are lower than the height of the through pipe 2451, so that the condensed liquid will not flow back to the bottom of the distillation shell 21. , sliding rods 244 are fixedly connected to both ends of the water storage plate 242, and a matching card slot 246 is opened at the corresponding position of the liquid accumulation bottom plate 241, and a limiting component is arranged inside the card slot 246, and a cover plate for preventing the water storage plate 242 from falling off downward is fixedly connected to the two sliding rods 244, so that the water storage plate 242 will slide downward only when the water storage tank 243 is full of water, and the interior of the bubble cover 2452 is fixedly connected to the limiting rod 2455 through the connecting rod 2454, and a movable groove 2456 matching the limiting rod 2455 is opened inside the through pipe 2451, so that the bubble cover 2452 will not fall off from the through pipe 2451;

[0041] The pressure assembly 25 includes a pressure bottom plate 251, both ends of the pressure bottom plate 251 are fixedly connected to the limit plate 253, and the interior of the distillation shell 21 is provided with a matching groove, and the pressure bottom plate 251 is also provided with equidistantly arranged air holes 252 to evenly generate the mixed gas, and the pressure bottom plate 251 is also provided with a plurality of discharge members 254, and the discharge member 254 includes a movable tube 2541 movably connected to the inside of the movable tube 2541 through a limit block 2543, and the movable tube 2541 is provided with a through hole 2542, and the movable tube 2541 is provided with a material slot for placing the desiccant, and the through hole 2542 matches the material slot. The pressure bottom plate 251 is also fixedly connected to a transmission member 255 at the bottom, and the transmission member 255 includes an annular rack 2551 and a half gear 2552 meshed with the inside of the annular rack 2551, so that the half gear 2552 is driven to rotate when the pressure bottom plate 251 rises. A connecting plug 2554 is fixedly connected to the half gear 2552, and the connecting plug 2554 is movably connected to the inside of the connecting valve 2553, so that when the half gear 2552 rotates, the connecting plug 2554 is driven to rotate inside the connecting valve 2553, and the upper end of the connecting valve 2553 is connected to the surrounding pipe 9.

[0042] During operation, the antioxidant enters the distillation shell 21 of the distillation mechanism 2 from the feed port 7. During the distillation process, the generated gas rises and encounters the condenser 23 in the top cover 22. The coolant flows in the condenser 23 to condense the gas into liquid. The condensed liquid drips onto the liquid accumulation component 24. The liquid flows into the through pipe 2451 through the hole groove 2453 on the bubble cover 2452, and then drips into the water storage tank 243 of the water storage plate 242. As the liquid continues to accumulate, when the water storage tank 243 is full of water, the water storage plate 242 overcomes the resistance of the limit assembly under the action of gravity and flows along the liquid accumulation component 24. As the card slot 246 slides downward, the discharge port 8 discharges liquid, so that the generated odorous gas will not overflow from the discharge port 8, and the bubble cover 2452 moves in the movable slot 2456 in the through pipe 2451 through the limiting rod 2455 to ensure that the bubble cover 2452 will not fall off the through pipe 2451. At the same time, the hole slot 2453 is lower than the height of the through pipe 2451 to ensure that the condensed liquid will not flow back to the bottom of the distillation shell 21. The gas generated during the distillation process is evenly generated through the pores 252. Mixed gas, as the distillation proceeds, when a large amount of gas is generated, the bottom The pressure increases, so that the movable tube 2541 rises along the pressure bottom plate 251. When it rises to a certain height, the desiccant inside the movable tube 2541 is aligned with the material slot through the through hole 2542, so that the desiccant is discharged from the pressure bottom plate 251 to absorb the moisture in the remaining solution, thereby reducing the amount of water in the remaining solution, thereby gradually balancing the pressure and reducing the boiling point of the solution, thereby accelerating the evaporation rate. When the pressure decreases, the pressure bottom plate 251 drops and drives the annular rack 2551 to move, so that the half gear 255 meshed with the annular rack 2551 is 2 rotates, and when the half gear 2552 rotates, it drives the connecting plug 2554 to rotate inside the connecting valve 2553. The upper end of the connecting valve 2553 is connected with the surrounding pipe 9, so that the water condensed by the condensing mechanism 3 enters the inside of the distillation mechanism 2 to increase the water content of the solution, thereby adjusting the evaporation rate of the solution, thereby avoiding the phenomenon of excessive evaporation. Excessive evaporation will destroy the originally expected separation effect, making it impossible to effectively separate the antioxidant and the odor components, resulting in a large amount of odor components remaining in the antioxidant, affecting the product quality, and failing to achieve the expected goal of deodorization.

[0043] As an embodiment of the present invention, Figure 1 and 3 As shown, the condensing mechanism 3 includes a condensing base 31, to which a heat exchange tube 36 for heat exchange is fixedly connected via a support base 32, and a water outlet pipe 34 and an air inlet 35 are fixedly connected at the upper and lower ends of the heat exchange tube 36, and a partition 33 for isolating gas and liquid is arranged inside the support base 32, and the air inlet 35 is interconnected with the incineration mechanism 5 to absorb the water vapor generated by the incineration mechanism 5, and the water outlet pipe 34 is connected with the surrounding pipe 9 via a connecting pipe 6 to supply water to the interior of the distillation mechanism 2.

[0044] During operation, the water vapor generated by the incineration mechanism 5 enters the heat exchange tube 36 from the air inlet 35, and the partition 33 inside the support seat 32 plays a role in isolating the gas and liquid. The water vapor exchanges heat with the outside in the heat exchange tube 36, and the condensed water flows out from the water outlet pipe 34, and is connected with the surrounding pipe 9 through the connecting pipe 6 to supply water to the interior of the distillation mechanism 2, thereby reducing the waste of water resources and reducing the demand for external fresh water sources.

[0045] As an embodiment of the present invention, Figure 1 and Figure 4 As shown, the incineration mechanism 5 includes an equipment shell 51 and an incineration chamber 53 opened inside the equipment shell 51, and the equipment shell 51 is fixed on the incinerator base 4, and an air inlet pipe 52 and an air outlet pipe 54 are opened at the upper and lower ends of the equipment shell 51, and two exhaust pipes 55 for air intake are fixedly connected to the bottom of the equipment shell 51, and the two exhaust pipes 55 are connected to the interior of the distillation shell 21 for transmitting exhaust gas, and the exhaust pipe 54 is connected to the condensation mechanism 3 to condense the generated water vapor, and the air inlet pipe 52 is connected to the external oxygen supplier to promote incineration.

[0046] During operation, the exhaust gas in the distillation shell 21 enters the incineration chamber 53 inside the equipment shell 51 through the exhaust pipe 55, and the external oxygen supplier supplies oxygen to the incineration chamber 53 through the air inlet pipe 52 to promote the incineration of the exhaust gas. The water vapor generated by the incineration is discharged from the air outlet pipe 54 and enters the condensation mechanism 3 for condensation, thereby processing the separated odorous gas to avoid environmental pollution, and at the same time recycling the generated water resources.

[0047] Working principle: When working, the antioxidant enters the distillation shell 21 of the distillation mechanism 2 from the feed port 7. During the distillation process, when a large amount of gas is generated, the pressure at the bottom increases, thereby raising the movable tube 2541 along the pressure bottom plate 251. When it rises to a certain height, the desiccant inside the movable tube 2541 is aligned with the material tank through the through hole 2542, so that the desiccant is discharged from the pressure bottom plate 251 to absorb the moisture in the remaining solution, thereby reducing the amount of water in the remaining solution, thereby gradually balancing the pressure and reducing the boiling point of the solution, thereby accelerating the evaporation rate. When the pressure decreases, the pressure bottom plate 251 drops to drive the annular rack 2551 to move, thereby causing the half gear 2552 meshed with the inside of the annular rack 2551 to rotate, and the half gear 2552 meshed with the inside of the annular rack 2551 rotates. When the gear 2552 rotates, the connecting plug 2554 is driven to rotate inside the connecting valve 2553. The upper end of the connecting valve 2553 is connected to the surrounding pipe 9, so that the water condensed by the condensing mechanism 3 enters the interior of the distillation mechanism 2 to increase the water content of the solution, thereby adjusting the evaporation rate of the solution, thereby avoiding the phenomenon of excessive evaporation. Excessive evaporation will destroy the originally expected separation effect, making it impossible to effectively separate the antioxidant and the odor components, resulting in a large amount of odor components remaining in the antioxidant, affecting the product quality, and failing to achieve the expected goal of deodorization. At the same time, when the gas rises, the bubble cover 2452 moves in the movable groove 2456 in the through pipe 2451 through the limiting rod 2455 to ensure that the bubble cover 2452 will not be separated from the through pipe 2451. The bubble cap 2452 is disengaged from the top, and the hole groove 2453 is lower than the height of the through pipe 2451, ensuring that the condensed liquid will not flow back to the bottom of the distillation shell 21. The gas generated during the distillation process is uniformly generated as a mixed gas through the air holes 252 until the antioxidant gas encounters the condenser tube 23 in the top cover 22. The coolant flows in the condenser tube 23 to condense the gas into liquid. The condensed liquid drips on the liquid accumulation component 24. The liquid flows into the through pipe 2451 through the hole groove 2453 on the bubble cap cover 2452, and then drips into the water storage tank 243 of the water storage plate 242. As the liquid continues to accumulate, when the water storage tank 243 is full of water, the water storage plate 242 overcomes the resistance of the limit assembly under the action of gravity and slides downward along the card groove 246. At this time, the discharge port 8 discharges the liquid. , so that the generated odorous gas will not overflow from the discharge port 8, and at the same time, the odorous gas is transported to the incineration mechanism 5, and the exhaust gas in the distillation shell 21 enters the incineration chamber 53 inside the equipment shell 51 through the exhaust pipe 55, and the external oxygen supplier supplies oxygen to the incineration chamber 53 through the air inlet pipe 52 to promote the incineration of the exhaust gas. The water vapor generated by the incineration is discharged from the air outlet pipe 54 and enters the condensation mechanism 3 for condensation, so as to treat the separated odorous gas to avoid environmental pollution. At the same time, the generated water resources are recycled. The water vapor generated by the incineration mechanism 5 enters the heat exchange tube 36 from the air inlet 35, and the partition 33 inside the support seat 32 plays a role in isolating gas and liquid. The water vapor exchanges heat with the outside world in the heat exchange tube 36, and the condensed water flows out from the water outlet pipe 34.The connecting pipe 6 is connected to the surrounding pipe 9 to supply water to the interior of the distillation mechanism 2, thereby reducing the waste of water resources and the demand for external fresh water sources.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
