[0002] As a compound widely used in the fields of chemical industry, medicine, fuel, etc., a large amount of waste ethanol will be generated during the production process of ethanol. If the waste ethanol is directly discharged into the environment without treatment, it will pollute the soil, water source and air. Recycling waste ethanol can realize the reuse of resources, reduce the demand for new resource exploitation, and contribute to saving natural resources.

[0003] The presence of impurities will seriously affect the quality and performance of ethanol. Therefore, in order to obtain high-purity ethanol, an impurity removal device needs to be used for purification treatment. That is, through a series of physical or chemical methods, the impurities in ethanol are separated to obtain ethanol with higher purity. There are many specific purification methods, and distillation is one of the most commonly used methods. Distillation utilizes the difference in boiling points between ethanol and impurities. By heating, ethanol is vaporized, and then the vaporized ethanol is condensed and collected to achieve the purpose of purification.

[0004] However, the existing impurity removal devices usually have a relatively simple structure. Although the static distillation method is easy to operate, during the static process, the contact area between ethanol and the heat source is limited, resulting in low heat transfer efficiency, uneven heating, thereby prolonging the impurity removal efficiency and increasing energy consumption and production costs.

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] Refer to Figure 1 - Figure 2, An impurity removal device for ethanol processing, including a base 1, on which a distillation tank 2 is fixedly installed. The distillation tank 2 is in a ring structure, and jacket 3s are fixedly arranged on both the inner and outer sides of the distillation tank 2. Electric heating tubes 4 are fixedly installed between the jacket 3s and the distillation tank 2. A number of stirring rods 5 are distributed in an annular array inside the distillation tank 2. Stirring parts 6 are fixedly arranged on a number of the stirring rods 5. A support 7 is fixedly arranged on the base 1 inside the distillation tank 2. A driving assembly is arranged at the top of the support 7 and is used to drive the stirring rods 5 to move inside the distillation tank 2. Feeding pipes 8 and exhaust pipes 9 are respectively communicated and arranged on both sides of the top of the distillation tank 2. A slag discharge pipe for discharging impurities is also arranged at the bottom of the distillation tank 2, and a valve for controlling opening and closing is arranged on the slag discharge pipe.

[0024] The driving assembly includes a motor fixedly arranged on the support 7. A connecting frame 10 is fixedly arranged on the output shaft of the motor. A gear ring 11 is fixedly arranged on the connecting frame 10. A number of first gears 12 are meshed and driven on the outer side of the gear ring 11, and the number of a number of the first gears 12 is the same as the number of a number of the stirring rods 5. A transmission assembly is arranged between the first gear 12 and the corresponding stirring rod 5.

[0025] The transmission assembly includes a second gear 13 meshed and driven with the first gear 12. The upper end of the stirring rod 5 penetrates through the distillation tank 2 and is rotationally matched with the top of the distillation tank 2, and the second gear 13 is fixedly sleeved on the end of the stirring rod 5.

[0026] A protective shell 17 is fixedly arranged on the top of the distillation tank 2. The driving assembly is arranged inside the protective shell 17. By protecting components such as the driving assembly inside the protective shell 17, it prevents damage caused by dust, impurities, etc. to it, extends the service life of key components such as the driving assembly, and reduces the maintenance cost.

[0027] The stirring part 6 includes a number of sheet-shaped stirring blades 601 located at the upper end of the stirring rod 5 and spiral stirring blades 602 located at the lower end of the stirring rod 5. The sheet-shaped stirring blades 601 and the spiral stirring blades 602 are combined and used on the stirring rod 5, which can give full play to the advantages of both and achieve comprehensive and uniform stirring of ethanol.

[0028] Working principle: When the device is in use, waste ethanol is added into the inside of the distillation tank 2 from the feeding pipe 8. The electric heating tubes 4 on both the inner and outer sides of the distillation tank 2 work, causing the inside of the distillation tank 2 to heat up. After the ethanol is heated and vaporized, it is discharged from the exhaust pipe 9. The exhaust pipe 9 is connected to a condenser to re-condense the vaporized ethanol into a liquid state for collection. The electric heating tubes 4 are distributed on both the inner and outer sides of the distillation tank 2, greatly increasing the contact area between the heat source and ethanol, improving the heat transfer efficiency. At the same time, the driving assembly drives the stirring rods 5 to move inside the distillation tank 2, causing the stirring part 6 to stir the waste ethanol, enhancing the convection, being conducive to the uniform heating of ethanol, further promoting the separation of ethanol and impurities, and improving the efficiency of impurity removal.

[0029] The specific implementation manner of the driving component is as follows: Start the motor, the motor drives the connecting frame 10 and the gear ring 11 to rotate, the gear ring 11 pushes a plurality of first gears 12 to rotate, and the first gears 12 drive the stirring rod 5 to move through the transmission component. The structure is compact and the transmission is stable, and the simultaneous driving of a plurality of stirring rods 5 can be realized. In this embodiment, the transmission component adopts a second gear 13, and the second gear 13 is driven to rotate synchronously by the first gear 12, and then drives the stirring rod 5 to rotate around its axis.

[0030] Embodiment 2: The difference from Embodiment 1 is that the transmission component no longer includes the second gear 13, but as Figure 2 - Figure 3 shown, it includes a mounting seat arranged on the top of the distillation tank 2, a universal ball 14 is arranged in the mounting seat, a plurality of mounting brackets for mounting the first gear 12 are arranged on the top of the distillation tank 2, and a driving rod 15 is concentrically fixed on the first gear 12. The upper end of the stirring rod 5 penetrates through the center of the universal ball 14 and is provided with a connecting rod 16, and the connecting rod 16 is rotationally matched with the end of the driving rod 15.

[0031] Working principle: Through the flexible rotation of the universal ball 14, when the first gear 12 drives the driving rod 15 to rotate, the connecting rod 16 is driven by the driving rod 15 to drive the stirring rod 5 to perform a circumferential rotation at a certain inclination angle in the distillation tank 2, which makes the stirring rod 5 generate stronger shear force and impact force during the stirring process, and has a more excellent stirring effect.

[0032] The above are only the preferred implementation manners of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
