Specific implementation

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the specification of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] With reference to Figure 1 and Figure 5 An embodiment provided by the utility model: a triethylamine high-concentration waste liquid recycling mechanism, comprising a recycling box 1, the outer wall of the recycling box 1 is fixedly connected with a connecting plate 2, the inner wall of the connecting plate 2 is fixedly connected with a feed inlet 3, the outer wall of the recycling box 1 is fixedly connected with a support 4, the outer wall of the support 4 is fixedly connected with a motor one 5, the output end of the motor one 5 is provided with a rotating column one 6, the outer wall of the motor one 5 is fixedly connected with a sleeve 7, the outer wall of the rotating column one 6 is fixedly connected with a fixed disc 8, both sides in the fixed disc 8 are fixedly connected with a quantitative tube 9, the outer wall of the quantitative tube 9 is provided with a cover plate 10, the outer wall of the cover plate 10 is slidably connected with a curved block 11, the outer wall of the curved block 11 is fixedly connected to the outer wall of the sleeve 7, the inside of the recycling box 1 is provided with a stirring assembly, and the stirring assembly is used for the action of fully mixing triethylamine waste liquid and chemical products.

[0026] Specifically, first, the waste liquid to be recycled is slowly injected into the recycling box 1 through the liquid inlet 26, and then the motor 5 is started to drive the rotating column 6 to rotate, and the rotation of the rotating column 6 in turn promotes the synchronous rotation of the fixed disc 8, and further drives the fixed disc 8 on both sides of the fixed disc 8. The fixed disc 8 starts to move in a circle with the rotating column 6 as the center axis, when the fixed disc 9 rotates to the precise position directly below the feed inlet 3 fixed by the connecting plate 2, the feed inlet 3 will accurately and accurately put the pre-stored specific chemicals into the fixed disc 9, at the same time, with the continuous movement of the fixed disc 9, the cover plate 10 is also driven synchronously, the curved block 11 fixed on the sleeve 7 is designed with a slope structure, when the cover plate 10 slowly slides along the slope, under the guidance of the slope, the cover plate 10 will be turned down, so that the chemicals contained in the fixed disc 9 can be smoothly dropped into the recycling box 1 through the feed pipe 28. Since the volume of the fixed disc 9 is strictly calibrated, the amount of chemicals added to the recycling box 1 each time can be accurately controlled, realizing quantitative feeding, which can effectively improve the purity of the recovered triethylamine, so that each index perfectly meets the strict requirements of being put into production again, and the negative impact on the subsequent production process due to insufficient purity is minimized.

[0027] Referring to Figure 2 , the stirring assembly comprises a motor 12, the outer wall of the motor 12 is fixedly connected to the lower surface of the recycling box 1, the output end of the motor 12 is provided with a rotating column 13, and the outer wall of the rotating column 13 is fixedly connected with stirring rods 14.

[0028] Specifically, the motor 12 is started to drive the rotating column 13 to rotate, and the rotation of the rotating column 13 drives the stirring rods 14 to rotate in the recycling box 1, and under the strong stirring action of the stirring rods 14, the waste liquid and the chemicals just added can be fully and uniformly mixed, laying a solid foundation for the subsequent recycling process.

[0029] Referring to Figure 1 , Figure 3 and Figure 4 , the outer wall of the recycling box 1 is fixedly connected with a connecting frame 15, the inside of the connecting frame 15 is slidably connected with a limiting rod 16, the upper surface of the limiting rod 16 is fixedly connected with an intercepting frame 17, and the outer wall of the intercepting frame 17 is slidably connected to the upper surface of the connecting frame 15. The inside of the connecting frame 15 is fixedly connected with a fixed pipe sleeve 29, and the inside of the fixed pipe sleeve 29 is rotatably connected with a rotating disc 18. The inner wall of the rotating disc 18 is fixedly connected with a connecting column 19, the outer wall bottom of the connecting column 19 is fixedly connected with a limiting column 20, and the outer wall of the limiting column 20 is attached to the inner wall of the fixed pipe sleeve 29. The outer wall of the connecting column 19 is fixedly connected with a pressing disc 21, the outer wall of the pressing disc 21 is fixedly connected with a spring 22, the outer wall of the spring 22 is fixedly connected with an outer shell 24, and the upper surface of the connecting column 19 is fixedly connected with a pressing column 23.

[0030] Specifically, the pressing column 23 is pressed downward, and the pressing column 23 starts to move vertically downward after being stressed, and synchronously drives the connecting column 19 to move downward, and along with the downward movement of the connecting column 19, the rotating disc 18 and the limiting column 20 connected thereto also move, so that the limiting column 20 changes position and no longer closely fits the inner wall of the fixed sleeve 29. In the process of moving the rotating disc 18 driven by the connecting column 19, the pressing disc 21 is also synchronously displaced downward, and the downward movement of the pressing disc 21 exerts pressure on the spring 22, so that the spring 22 is gradually compressed to store elastic potential energy. Then the pressing column 23 is rotated, and the spring 22 is driven to move rapidly by the rebounding force accumulated by the spring 22 being compressed previously, so as to make the limiting column 20 completely escape from the internal space restraint of the fixed sleeve 29. Subsequently, the operator pulls the pressing column 23 outward, and the pressing column 23 drives the shell 24 to slide outward, so that the shell 24 escapes from the internal accommodation area of the intercepting frame 17. Finally, the intercepting frame 17 is continuously pulled outward, and the intercepting frame 17 drives the limiting rod 16 to slowly move out of the inside of the connecting frame 15, so that the intercepting frame 17 is completely disassembled, which greatly facilitates the staff to clean the filter screen in the intercepting frame 17 comprehensively and carefully, and provides strong guarantee for the smooth development of the subsequent recycling process.

[0031] With reference to Figure 1 - Figure 3 The upper surface of the intercepting frame 17 is slidably connected with an upper box 25, and the upper box 25 is internally provided with a liquid inlet 26.

[0032] Specifically, the upper box 25 supports the liquid inlet 26 and prevents the liquid inlet 26 from shaking left and right.

[0033] With reference to Figure 1 The outer wall of the recycling box 1 is provided with a feeding pipe 28, and the inside of the recycling box 1 is provided with a liquid outlet valve 27.

[0034] Specifically, after the chemical substances entering the feeding pipe 28 are fully mixed with the waste liquid, the mixed solution inside is easily discharged through the opening of the liquid outlet valve 27.

[0035] Working principle: when the mechanism needs to be used, first add the high-concentration waste liquid of triethylamine to be recycled from the liquid inlet 26 fixed by the upper box 25 into the inside of the recycling box 1. When the waste liquid falls downward, it will first pass through the filter screen inside the intercepting frame 17 to screen out impurities, preventing adverse effects on subsequent chemical reactions. When a certain amount of waste liquid is added, start the motor one 5 fixed by the support 4. The motor one 5 drives the rotating column one 6 to rotate, which in turn drives the fixed disc 8 to rotate. The fixed disc 8 drives the two side quantitative pipes 9 to rotate around the rotating column one 6 as the axis. When the quantitative pipe 9 rotates to the lower side of the feed inlet 3 fixed by the connecting plate 2, the feed inlet 3 adds the chemical inside to the inside of the quantitative pipe 9. The quantitative pipe 9 moves while driving the cover plate 10 to move. Because the curved block 11 fixed by the sleeve 7 is provided with a slope, when the cover plate 10 passes through the slope of the curved block 11, the cover plate 10 will flip downward, which in turn makes the chemical inside fall into the inside of the feed pipe 28. Through the feed pipe 28, the chemical enters the inside of the recycling box 1. Because the capacity of the quantitative pipe 9 is certain, the chemical added to the inside of the recycling box 1 is also quantitative. Then start the motor two 12. The motor two 12 drives the rotating column two 13 to rotate, which in turn drives the stirring rod 14 to rotate, so that the waste liquid and the chemical are fully mixed. After the reaction is completed, the inside solution is discharged through the open-close liquid outlet valve 27, which improves the purity of the recycled triethylamine and makes it more suitable for reuse, reducing the impact on the subsequent production process. When the waste liquid is mixed, the filter screen inside the intercepting frame 17 needs to be cleaned. At this time, press down the pressing column 23. The pressing column 23 drives the connecting column 19 to move, which in turn drives the rotating disc 18 and the limiting column 20 to move, so that the limiting column 20 no longer fits the inner wall of the fixed pipe sleeve 29. When the connecting column 19 drives the rotating disc 18 to move, it also drives the lower pressing disc 21 to move, which in turn compresses the spring 22. Rotate the pressing column 23. Through the rebound of the spring 22, the connecting column 19 and the limiting column 20 are driven to move, so that the limiting column 20 is separated from the inside of the fixed pipe sleeve 29. Pull the pressing column 23 to drive the shell 24 to separate from the inside of the intercepting frame 17. Pull the intercepting frame 17 outward, which in turn drives the limiting rod 16 to separate from the inside of the connecting frame 15. At this time, the intercepting frame 17 is completely disassembled, which is convenient for cleaning the filter screen inside the intercepting frame 17. That is, the structure not only improves the purity of the recycled triethylamine, makes it more suitable for reuse, and reduces the impact on the subsequent production process, but also facilitates the cleaning of the filter screen inside the intercepting frame 17.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
