[0023] 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.
[0024] Please see Figure 1-6 An energy-saving separation device for acetic acid distillation includes a distillation tank 1, with an insulation box 2 placed on the right side of the distillation tank 1. An inlet pipe 3 and a pressure reducing pipe 6 pass through the outer wall of the distillation tank 1. An igniter 15 is installed at one end of the inlet pipe 3 inside the distillation tank 1. A feed pipe 4 and a reflux pipe 8 pass through the top of the distillation tank 1. A sealing cap 5 is threaded onto the outer wall of the feed pipe 4. A circular pipe 7 passes through the outer wall of the pressure reducing pipe 6. An electromagnetic pressure reducing valve 13 is installed at the connection between the pressure reducing pipe 6 and the distillation tank 1. A discharge pipe 9 is provided between the distillation tank 1 and the insulation box 2. Limited openings are made in the inner wall of the distillation tank 1. The inner wall of the distillation tank 1 is rotatably connected to the hopper 11, and the outer wall of the hopper 11 is fixedly fitted with a limit ring 10. The top of the inner wall of the distillation tank 1 is fixedly mounted with a round rod 16, and the bottom end of the round rod 16 is fixedly mounted with a stirring rod 17. The bottom of the inner wall of the distillation tank 1 is fixedly mounted with a pressure sensor 14. The inner wall of the insulation box 2 is bonded with an insulation jacket 12. The inner wall of the distillation tank 1 is fixedly mounted with a fixing plate 19, and the top of the fixing plate 19 is fixedly mounted with a motor 20. The output shaft of the motor 20 is fixedly mounted with a gear 21, and the outer wall of the gear 21 is meshed with a gear ring 22.
[0025] In the above structure, the setup of the distillation tank 1, insulation box 2, air inlet pipe 3, feeding pipe 4, sealing cover 5, limiting ring 10, hopper 11, igniter 15, limiting groove 18, motor 20, and gear 21 allows the device to operate by using the motor 20 to engage the gear 21 with the gear ring 22. This causes the hopper 11 to rotate around the center point of the distillation tank 1, ensuring that the hopper 11 is evenly heated after the igniter 15 ignites the carbon monoxide. The rotation of the hopper 11, in conjunction with the stirring rod 17, stirs the acetic acid inside the hopper 11, thereby improving the distillation efficiency of the acetic acid.
[0026] In a preferred embodiment, the inner wall of the air intake pipe 3 is filled with carbon monoxide, and both the hopper 11 and the stirring rod 17 are made of tempered glass.
[0027] In the above structure, tempered glass has good hardness characteristics, which can ensure that the stirring rod 17 will not break when stirring the material. At the same time, the glass material cannot react with acetic acid, thus ensuring that neither of them will be corroded by acetic acid, thereby ensuring that the subsequent use of the device will not be affected.
[0028] In a preferred embodiment, the inner wall of the toothed ring 22 is fixedly assembled with the outer wall of the hopper 11, and the inner wall of the limiting groove 18 is rotatably connected with the outer wall of the limiting ring 10.
[0029] In the above structure, the limiting ring 10, hopper 11 and limiting groove 18 are designed so that when the gear 21 meshes with the gear ring 22, the limiting ring 10 will limit the hopper 11, thereby preventing the hopper 11 from tilting or even shifting position during rotation, thus improving the stability of the hopper 11 during rotation.
[0030] In a preferred embodiment, a solenoid valve is provided at the connection between the discharge pipe 9 and the hopper 11, and a controller is fixedly mounted on the outer wall of the distillation tank 1, and the controller is electrically connected to the solenoid valve and the motor 20 respectively.
[0031] In the above structure, the solenoid valve allows acetic acid to accumulate in the hopper 11 after the user removes the sealing cover 5 and pours acetic acid into the hopper 11. This allows the igniter 15 to ignite carbon monoxide to heat the hopper 11, ensuring that all impurities in the acetic acid are removed by the distillation process. This achieves the effect of distillation and purification of acetic acid, ensuring the production quality of acetic acid.
[0032] In a preferred embodiment, there are several stirring rods 17, and all of the stirring rods 17 are evenly distributed along the outer wall of the round rod 16.
[0033] In the above structure, the stirring rod 17 stirs the acetic acid inside the hopper 11 during the rotation of the hopper 11, causing the acetic acid deposited at the bottom to tumble. This increases the contact area between heat and acetic acid, thereby improving the distillation effect of the device on acetic acid. During this process, the rotation of the hopper 11 not only ensures that the acetic acid is heated evenly, but also simultaneously achieves the effect of stirring the acetic acid, improving the energy utilization rate of the device and playing an energy-saving role.
[0034] In a preferred embodiment, the outer wall of the stirring rod 17 overlaps with the inner wall of the hopper 11, and the hopper 11 is connected to the outside through the discharge pipe 9.
[0035] In the above structure, through the discharge pipe 9 and hopper 11, the discharge pipe 9 can discharge the distilled acetic acid, which makes it convenient for users to extract the distilled acetic acid. After extraction, the cleaning water can be discharged directly when cleaning the equipment, which makes it convenient for users to maintain the device and improves the practicality of the device.
[0036] In a preferred embodiment, the distillation tank 1 is connected to the interior of the insulation box 2 via a pressure reducing pipe 6, and the insulation jacket 12 is made of polyethylene foam.
[0037] In the above structure, the polyethylene foam is non-absorbent and does not allow water vapor to pass through. During the distillation process, the hot air expands, and the pressure sensor 14 is used to sense the air pressure, allowing the hot air to enter the insulation box 2 for decompression. This not only ensures the safety of the device during operation, but also allows the hot air to be stored in the insulation box 2. Combined with the insulation effect of the insulation jacket 12, the hot air can be discharged back into the distillation tank 1 for reuse, thereby improving the energy efficiency and safety of the device during operation.
[0038] In a preferred embodiment, the air outlet of the insulation jacket 12 is fixedly assembled with the end of the return pipe 8, and the end of the round pipe 7 is fixedly assembled with the air inlet of the insulation jacket 12.
[0039] In the above structure, the circular tube 7 and the insulation jacket 12 allow high-pressure, high-heat air to enter the insulation jacket 12 through the opening of the electromagnetic pressure reducing valve 13, thereby venting the high-pressure, high-heat air to ensure that the distillation tank 1 will not burst, thus improving the safety of the device during operation. During the heating process, the high-heat air inside the insulation jacket 12 suffers minimal heat loss due to the insulation effect and can be directly discharged back into the distillation tank 1 to reduce the combustion and loss of carbon monoxide, thereby effectively reducing energy consumption.
[0040] Working principle: First, the user rotates the sealing cap 5 to pour acetic acid into the hopper 11. Then, the igniter 15 ignites carbon monoxide to heat the hopper 11. During the heating process, the rotation of the hopper 11 ensures that the acetic acid is heated evenly. This, combined with the stirring rod 17, increases the contact area between the acetic acid and the heat, thereby improving the distillation effect of the device on acetic acid. During the heating process, the air expands due to heat. At this time, the pressure sensor 14, in conjunction with the controller, opens the electromagnetic pressure reducing valve 13 to reduce the pressure, allowing the high-temperature, high-pressure air to enter the insulation jacket 12 for insulation. In subsequent heating processes, the high-pressure, high-temperature air is discharged back into the distillation tank 1 to maintain a high-temperature environment, thereby reducing the combustion and use of carbon monoxide and achieving energy saving.
