Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a propylene glycol drying device. Background Technology

[0002] Propylene glycol has good hygroscopic properties, so in some specific application scenarios, propylene glycol may form solid particles. When the water content of propylene glycol is too high and it is placed in a high temperature and high humidity environment, it will absorb more moisture, causing it to crystallize and form a particle-like structure.

[0003] Propylene glycol absorbs a large amount of water, which leads to a decline in its quality or poor performance. Drying can significantly reduce the water content of propylene glycol, thereby improving its purity and stability, reducing chemical reactions after mixing with other substances, and improving the quality and stability of the product. Currently, the drying effect of propylene glycol crystal particles is relatively poor.

[0004] Therefore, a propylene glycol drying apparatus is provided to improve the drying effect of propylene glycol crystals. Utility Model Content

[0024] Reference Figure 1-6 This invention provides a propylene glycol drying device, which includes an outer tank 1, a drying tank 4 inside the outer tank 1, the outer tank 1 and the drying tank 4 being coaxially arranged, the drying tank 4 having a regular polygonal cross-section, and water films 41 being provided on the edges of the drying tank 4; multiple support seats 11 being provided at the bottom of the outer tank 1, support plates 12 being provided inside the support seats 11, a motor 2 being provided at the top of the support plates 12, a feed pipe 13 being provided on the top surface of the outer tank 1, the other end of the feed pipe 13 being located on the top surface of the drying tank 4, and a discharge pipe 14 being provided on the bottom surface of the outer tank 1, the other end of the discharge pipe 14 being located on the bottom surface of the drying tank 4.

[0025] Specifically, a drying tank 4 is installed inside the outer tank 1. The outer tank 1 and the drying tank 4 are coaxially arranged. The cross-section of the drying tank 4 is a regular polygon. Water outlet films 41 are provided on the edges of the drying tank 4. The outer tank 1 provides support and protection for the drying tank 4. Undried propylene glycol crystals are placed into the drying tank 4. During the movement of the drying tank 4, the propylene glycol and water are separated, and the water enters the interior of the outer tank 1 through the water outlet films 41. Multiple support seats 11 are provided at the bottom of the outer tank 1. Support plates 12 are installed inside the support seats 11. A motor 2 is installed on the top of the support plate 12. The outer tank 1 is supported by the support base 11, and the motor 2 is supported by the support plate 12. A feed pipe 13 is installed on the top surface of the outer tank 1, and the other end of the feed pipe 13 is located on the top surface of the drying tank 4. A discharge pipe 14 is installed on the bottom surface of the outer tank 1, and the other end of the discharge pipe 14 is located on the bottom surface of the drying tank 4. Undried propylene glycol crystals enter the interior of the drying tank 4 through the feed pipe 13, and dried propylene glycol is discharged from the drying tank 4 through the discharge pipe 14.

[0026] The top surface of the motor 2 is provided with a drive shaft 21, which is coaxial with the outer tank 1. The other end of the drive shaft 21 is connected to the top surface of the drying tank 4. A pair of auxiliary plates 22 are provided on the drive shaft 21, which are closely attached to the two ends of the bottom surface of the outer tank 1.

[0027] Specifically, the drive shaft 21 is driven to rotate by the motor 2, which in turn drives the drying tank 4 to rotate. Centrifugal force is generated inside the drying tank 4 to accelerate the separation of propylene glycol and water. The drive shaft 21 can rotate independently from the outer tank 1 through the auxiliary plate 22.

[0028] A balance shaft 23 is provided on the top surface of the drying tank 4. The other end of the balance shaft 23 is located on the outer side of the top surface of the outer tank 1. A pair of auxiliary plates 22 are also provided on the balance shaft 23. The auxiliary plates 22 are closely attached to both ends of the top surface of the outer tank 1.

[0029] Specifically, the rotation of the drying tank 4 is balanced by the balance shaft 23, and the balance shaft 23 can rotate independently of the outer tank 1 by the auxiliary plate 22.

[0030] The top surface of the drying tank 4 is provided with a slide 42, and a feed inlet 43 is provided on one side of the slide 42. A feed hinge 44 is provided inside the feed inlet 43. The size of the slide 42 is the same as the diameter of the feed pipe 13. The bottom of the feed pipe 13 is located inside the slide 42 on the top surface of the drying tank 4. The bottom surface of the drying tank 4 is also provided with a slide 42, and a discharge outlet 45 is provided on one side of the slide 42. The discharge outlet 45 is located on the opposite side of the feed inlet 43. A discharge hinge 46 is provided inside the discharge outlet 45. The size of the discharge outlet 45 is the same as the size of the discharge pipe 14. The top of the discharge pipe 14 is located inside the slide 42 on the bottom surface of the drying tank 4.

[0031] Specifically, the feed pipe 13 and the discharge pipe 14 are fixed on the top and bottom surfaces of the outer tank 1, respectively. When the drying tank 4 rotates, the other ends of the feed pipe 13 and the discharge pipe 14 rotate on the slides 42 at both ends of the drying tank 4. By controlling the lifting and lowering of the feed pipe 13 and the discharge pipe 14, the feed pipe 13 pushes the feed hinge 44 to connect with the feed port 43, and the discharge pipe 14 pushes the discharge hinge 46 to connect with the discharge port 45, thus completing the feeding and discharging.

[0032] An air extraction pipe 31 is provided on the top surface of the outer tank 1. The air extraction pipe 31 is connected to the inside of the outer tank 1, and an air pump 3 is provided at the other end of the air extraction pipe 31.

[0033] Specifically, the water inside the outer tank 1 is extracted from the air extraction pipe 31 by the air extraction pump 3.

[0034] An air inlet 15 is provided at the bottom of the outer tank 1, and a filter layer 16 is provided inside the air inlet 15. The top surface of the filter layer 16 is flush with the top of the bottom of the outer tank 1.

[0035] Specifically, the outer tank 1 is connected to the outside air through the air inlet 15 to replenish the air inside the outer tank 1. The air entering the outer tank 1 is filtered through the filter layer 16 to prevent impurities in the air from entering the drying tank 4 through the water outlet membrane 41 and contaminating the propylene glycol.

[0036] During operation, the feed pipe 13 is raised and lowered to connect it to the drying tank 4, allowing propylene glycol to be added to the drying tank 4 through the feed pipe 13. The motor 2 drives the drying tank 4 to rotate, causing the propylene glycol crystals inside the drying tank 4 to rotate faster, thus accelerating the separation of propylene glycol and water. The separated water is discharged into the interior of the drying tank 4 through the water outlet membrane 41, while the propylene glycol remains isolated inside the drying tank 4. The vacuum pump 3 is then driven to extract the water from the interior of the outer tank 1. The discharge pipe 14 is raised and lowered to connect it to the drying tank 4, allowing the propylene glycol inside the drying tank 4 to be discharged.
