[0020] Example 1
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, a 1,4-butanediol waste liquid recovery device includes a support frame 1, a base frame 2 fixed to the outer wall of the bottom end of the support frame 1, a waste liquid distillation tank 3 fixed inside the support frame 1, a heating pipe 4 arranged around the bottom end of the waste liquid distillation tank 3, a recovery chamber 5 opened inside the waste liquid distillation tank 3, a boiling chamber 6 arranged on one side of the recovery chamber 5, a sealing plate 7 arranged above the waste liquid distillation tank 3, a water pipe 13 connected through the top of the condenser plate 11, a first motor 14 fixed above the closed cover 8, a first rotating shaft 15 arranged at the rotating end of the first motor 14, a first bearing 16 installed around the outer side of the first rotating shaft 15, a threaded bolt 17 threadedly connected to the inner side of the first rotating shaft 15, a support rod 18 fixedly connected below the threaded bolt 17, mounting holes 19 are opened on the side walls of both the threaded bolt 17 and the first rotating shaft 15, a locking post 20 is arranged inside the mounting hole 19, and a washing plate 21 is fixed on the side wall of the support rod 18.
[0022] The bottom of the waste liquid distillation tank 3 is provided with a first discharge valve 27, and the bottom of the side wall of the waste liquid distillation tank 3 is provided with a second discharge valve 28. The waste after distillation can be discharged through the first discharge valve 27, while the light phase components methanol and water in the distilled waste liquid will be discharged from the first discharge valve 27.
[0023] The first rotating shaft 15 is driven by the first motor 14 to rotate. The first rotating shaft 15 and the support rod 18 form a detachable structure through the threaded bolt 17. The support rod 18 and the washing plate 21 form a fixed structure. The support rod 18 can be installed below the first rotating shaft 15 through the threaded bolt 17. The side wall of the support rod 18 is provided with multiple sets of washing plates 21. Driven by the first motor 14, the first rotating shaft 15 and the support rod 18 can be driven to rotate, which indirectly drives the multiple sets of washing plates 21 to rotate. The rotation of the multiple sets of washing plates 21 can wash the inner wall of the waste liquid distillation tank 3, thereby preventing waste liquid residue inside the waste liquid distillation tank 3. Furthermore, it can be disassembled when waste liquid distillation is required.
[0024] Example 2
[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment further illustrates Example 1. A closed cover 8 is provided above the sealing plate 7. A feed port 9 is provided on the upper surface of the closed cover 8. A connecting plate 10 is fixed to the inner wall of the closed cover 8. A condensing plate 11 is fixed to the other end of the connecting plate 10. A diversion plate 12 is fixed to the lower wall of the condensing plate 11. The condensing plate 11 and the closed cover 8 form a fixed structure through the connecting plate 10. The diversion plate 12 is fixed to the condensing plate 11. Multiple sets of diversion plates 12 are distributed at equal intervals below the condensing plate 11. They are heated by the heating tube 4. When the temperature reaches a certain level, the high-boiling-point substances carried by the gaseous methanol and water are condensed into large particles under the action of the top condensing plate 11 and fall into the recovery chamber 5 through the connecting plate 10.
[0026] Example 3
[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further illustrates Example 1. A second motor 22 is fixed inside the top of the support frame 1. A threaded post 23 is provided at the rotating end of the second motor 22. A threaded plate 24 is threadedly connected to the outer periphery of the threaded post 23. A slider 25 is fixed to the other side wall of the closed cover 8. A slide rail 26 is provided on the outer side of the slider 25. The threaded post 23 rotates under the drive of the second motor 22. The threaded post 23 and the threaded plate 24 form a threaded connection. The threaded plate 24 and the closed cover 8 are fixed to each other. The closed cover 8 forms a sliding structure through the slider 25 and the slide rail 26. Driven by the second motor 22, the threaded post 23 can be rotated. Through the threaded connection between the threaded post 23 and the threaded plate 24, the rotation of the threaded post 23 can cause the threaded plate 24 to rise and fall. The rising and falling of the threaded plate 24 can cause the closed cover 8 to rise and fall, thereby facilitating the clamping and disassembly of the support rod 18 and the washing plate 21 after the closed cover 8 is opened.
[0028] The closed cover 8 forms a closed structure with the waste liquid distillation tank 3 through the sealing plate 7.
[0029] Working principle: First, driven by the second motor 22, the threaded column 23 can be rotated. Through the threaded connection between the threaded column 23 and the threaded plate 24, the rotation of the threaded column 23 can cause the threaded plate 24 to rise and fall. The rising and falling of the threaded plate 24 can cause the closing cover 8 to rise and fall, thus facilitating the opening of the closing cover 8 and the clamping and disassembly of the support rod 18 and the washing plate 21. The support rod 18 can be installed below the first rotating shaft 15 through the threaded bolt 17. The side wall of the support rod 18 is provided with multiple sets of washing plates 21. Driven by the first motor 14, the first rotating shaft 15 and the support rod 18 can be rotated, indirectly causing the multiple sets of washing plates 21 to rotate. The rotation of the multiple sets of washing plates 21 can wash the inner wall of the waste liquid distillation tank 3, thereby preventing waste liquid residue inside the waste liquid distillation tank 3. Secondly, when waste liquid distillation is required, it can be disassembled.
