Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of sodium acetate recovery technology, and more specifically, to an apparatus for drying and recovering sodium acetate. Background Technology

[0002] Sodium acetate, as an important organic chemical raw material, has demonstrated wide application value in many fields. During the production of sodium acetate, a large amount of mother liquor containing sodium acetate is generated. Directly discharging this mother liquor into the environment will not only cause serious environmental pollution but also lead to a huge waste of resources. Therefore, the recycling and reuse of sodium acetate has significant economic and environmental implications. By recycling sodium acetate, production costs can be reduced, resource utilization can be improved, and negative environmental impacts can be minimized, thus meeting the requirements of sustainable development.

[0003] Current methods for recovering sodium acetate typically employ evaporation crystallization. This involves heating a sodium acetate solution to evaporate the water, causing the solution to become supersaturated, at which point sodium acetate crystals precipitate out. The crystallized sodium acetate is then separated from the mother liquor using a solid-liquid separation device, such as a filter or centrifuge. Finally, the separated sodium acetate crystals are dried to remove surface moisture, yielding a dried sodium acetate product.

[0004] However, in existing technologies, solutions containing sodium acetate are generally dried by heating in ovens or box dryers. However, during the evaporation and crystallization process, sodium acetate solutions tend to form scale on the inner wall surface of the equipment. Scale formation reduces the heat transfer efficiency of the equipment, increases the operating resistance of the equipment, and leads to increased energy consumption and decreased production efficiency.

The fixing post 10 extends into the fixing groove and is slidably connected to the sidewall of the fixing groove. The fixing ring 5 and the recycling bin 3 can be limited by the cooperation of the fixing post 10 and the fixing groove, thereby facilitating the improvement of the fixing stability of the recycling bin 3 in the drying cylinder 2.

[0051] Reference Figures 2-6The positioning mechanism includes a positioning ring 11, a positioning housing 12, positioning ports 13, positioning blocks 14, and a relative moving mechanism. The positioning ring 11 is fixedly mounted on the side wall of the drying cylinder 2. A first cavity is formed inside the mounting plate 7, and the positioning housing 12 is slidably mounted inside the first cavity. The exhaust pipe 9 passes through the positioning housing 12. Multiple positioning ports 13 are formed in a ring shape on the inner bottom wall of the positioning housing 12, and the positioning ports 13 penetrate the inner bottom wall of the first cavity. Multiple L-shaped positioning blocks 14 are slidably mounted on the inner top wall of the positioning housing 12 on one side of the positioning ports 13. The positioning blocks 14 extend out of the mounting plate 7 through the positioning ports 13. The relative moving mechanism is set inside the positioning housing 12 and is used to drive the multiple positioning blocks 14 to move synchronously. The relative moving mechanism includes an adjusting ring 15 and an adjusting... The rod 16 and the rotating mechanism are arranged in a way that the adjusting ring 15 is rotatably mounted on the inner top wall of the positioning housing 12. Multiple rotating shafts are rotatably mounted on the bottom side wall of the adjusting ring 15. An adjusting rod 16 is fixedly mounted on the side wall of the rotating shaft. The end of the adjusting rod 16 away from the rotating shaft is hinged to the adjacent positioning block 14. The rotating mechanism is mounted on the positioning housing 12 and is used to drive the adjusting ring 15 to rotate. A rubber pad is fixedly mounted on the positioning block 14. Specifically, the operation of the rotating mechanism can drive the adjusting ring 15 to rotate at a small angle. At the same time, during the rotation of the adjusting ring 15, the rotating shaft and the adjusting rod 16 can pull the positioning block 14 to move within the positioning port 13. Thus, the positioning block 14 and the positioning ring 11 are used to fix the drying cylinder 2 and the mounting plate 7.

[0052] Reference Figure 5 and Figure 6 The rotating mechanism includes a first gear ring, a first gear 17, and a driving mechanism. The first gear ring is fixedly mounted on the adjusting ring 15, and the first gear 17 is rotatably mounted on the inner top wall of the positioning housing 12. The first gear 17 meshes with the first gear ring. The driving mechanism is mounted on the mounting plate 7 and is used to drive the first gear 17 to rotate. The driving mechanism includes a driving prism 18 and a first motor 19. The positioning housing 12 has a driving port, and the driving prism 18 is rotatably mounted in the first cavity. The driving prism 18 passes through the driving port and the first gear 17. The driving prism 18 is slidably connected to the first gear 17. The first motor 19 is mounted on the mounting plate 7, and the output end of the first motor 19 is fixedly connected to the driving prism 18. Specifically, the operation of the first motor 19 can drive the driving prism 18 to rotate, and at the same time, through the sliding engagement between the driving prism 18 and the first gear 17, the first gear 17 is driven to rotate. Thus, through the meshing of the first gear 17 and the first gear ring, the adjusting ring 15 can be driven to rotate at a small angle.

[0053] Reference Figure 2 and Figure 4Multiple electric push rods 20 are installed on the inner top wall of the mounting plate 7. The output end of the electric push rod 20 is fixedly connected to the positioning housing 12. Specifically, the operation of the electric push rod 20 can drive the positioning housing 12 and the positioning block 14 to move. At the same time, the positioning block 14 squeezes the positioning ring 11, thereby improving the fixed stability between the mounting plate 7 and the drying cylinder 2.

[0054] Reference Figures 2-5 The descaling mechanism includes a stirring column 21 and a second motor 22. The stirring column 21 is installed through the mounting plate 7 and extends into the recovery tank 3. The stirring column 21 passes through the positioning housing 12 and the adjusting ring 15. A U-shaped scraper 23 is provided around the stirring column 21 and contacts the inner wall of the recovery tank 3. A stirring rod is fixed between the scraper 23 and the stirring column 21. The second motor 22 is installed on the mounting plate 7 and its output end is fixedly connected to the stirring column 21. The scraper 23, the stirring rod, and the stirring column 21 are coated with polytetrafluoroethylene. Specifically, the operation of the second motor 22 can drive the stirring column 21 to rotate, and at the same time, the stirring rod drives the scraper 23 to move around the stirring column 21, thereby cleaning the scale attached to the inner wall of the recovery tank 3.

[0055] In this embodiment, the operator inserts the recycling bin 3 into the drying cylinder 2 and adds sodium acetate solution to the recycling bin 3. Then, the operator inserts the sealing disc 8 into the sealing groove 4, making the mounting disc 7 contact the drying cylinder 2. The operator then controls the first motor 19 to operate, which drives the drive prism 18 to rotate. Simultaneously, the sliding engagement between the drive prism 18 and the first gear 17 drives the first gear 17 to rotate. This, in turn, allows the adjusting ring 15 to rotate at a small angle through the meshing of the first gear 17 and the first gear ring. During the rotation of the adjusting ring 15, the positioning block 14 can be moved within the positioning port 13 via the rotating shaft and adjusting rod 16. This, in turn, fixes the drying cylinder 2 and the mounting disc 7 through the engagement of the positioning block 14 and the positioning ring 11. Finally, the operator controls the electric push rod 20 to operate. The operation can move the positioning housing 12 and positioning block 14, and at the same time, the positioning block 14 squeezes the positioning ring 11, thereby improving the fixed stability between the mounting plate 7 and the drying cylinder 2. Then, the operator connects the exhaust pipe 9 to the condensation equipment and controls the heating wire 6 to work, so as to heat and evaporate the sodium acetate solution. After the sodium acetate solution crystallizes, it can continue to be heated and dried. During the heating process, the operator controls the second motor 22 to work, which drives the stirring column 21 to rotate. At the same time, the stirring rod drives the scraper 23 to move around the stirring column 21, thereby cleaning the scale attached to the inner wall of the recovery tank 3. After evaporation and crystallization are completed, the operator can control the electric push rod 20 and the first motor 19 to disassemble the mounting plate 7, so as to facilitate the recovery of the crystallized sodium acetate in the recovery tank 3.
