This process includes multiple reaction steps, such as addition reactions, substitution reactions, elimination reactions and rearrangement reactions.

[0003] During chemical experiments, when using filtering and distillation equipment, you first need to place the filter paper tightly in the funnel, and then pour the liquid to be filtered into the filter paper by manual pouring.

However, in the prior art, due to the funnel shape of the filter paper, concentrated pouring of the liquid may not fully and effectively utilize the surface area of ​​the entire filter paper, thereby affecting the filtration effect. This practice not only leads to low filtration efficiency, but also may increase experimental costs, because the underutilized filter paper needs to be replaced more frequently, thereby consuming more materials and time.

[0036] Reference Figure 1-11 A filtering and distilling device for fine chemical organic synthesis and a method of using the same include a stage 1, a vertical plate 9, a sinking platform 3, a distillation flask 61, a condenser 31, and a recovery cylinder 13. The condenser 31 of the distillation flask 61 is a device for cooling and condensing steam into a liquid. The specific structure includes an outer shell, an inner tube, a cooling water inlet and outlet, and a cooling water interlayer. Cooling water flows in the interlayer between the outer shell and the inner tube to condense the steam in the inner tube. The steam enters the inner tube through the steam inlet, condenses into a liquid after cooling, and is discharged through the condensate outlet. The distillation flask 61 and the condenser 31 are both common glass experimental instruments in laboratories, so the specific structure of the condenser 31 is not disclosed in detail in this application document.

[0037] A vertical plate 9 is vertically fixed on the top of the stage 1, a sinking platform 3 is provided at the top edge of the stage 1, a triangular plate 15 is fixed on the top edge of the vertical plate 9, a liquid guide bucket 14 is vertically fixed on the top of the triangular plate 15, a first connecting plate 10 and a second connecting plate 12 are fixed on the vertical plate 9 in sequence below the triangular plate 15, the first connecting plate 10 and the second connecting plate 12 are staggered in the vertical direction, a circular groove 11 is provided on the top of the first connecting plate 10 and the second connecting plate 12, a supporting assembly for stably supporting the filter bucket is provided inside the circular groove 11,

[0038] The support assembly includes a support ring 46, a driven pulley 45, and a bottom limit ring 47. The support ring 46 is movably inserted into the circular groove 11. The driven pulley 45 is fixedly provided at the top edge of the support ring 46. The support ring 46 is fixedly provided with a bottom limit ring 47 at the bottom of the second connecting plate 12 by a vertical bolt 48. The diameter of the bottom limit ring 47 is larger than the diameter of the circular groove 11. The bottom limit ring 47 and the driven pulley 45 limit the support ring 46 in the circular groove 11. In order to reduce the wear of the filter bucket placed on the support ring 46, a rubber ring can be additionally inlaid on the top of the support ring 46.

[0039] Therefore, when the two supporting components are placed in the glass filter funnel, the bottom of the filter funnel on the first connecting plate 10 is suspended on the top edge of the filter funnel on the second connecting plate 12. The liquid guide funnel 14 is a common separatory funnel in the laboratory, which can temporarily store the test solution to be filtered and distilled.

[0040] At this time, the bottom of the liquid guiding funnel 14 is at the top edge of the filter funnel on the first connecting plate 10. When the circular grooves 11 opened on the tops of the first connecting plate 10 and the second connecting plate 12 are both placed in the filter funnel, funnel-shaped filter papers are placed in the filter funnels, and the pore size of the filter paper on the first connecting plate 10 is larger than that on the second connecting plate 12. The two filter funnels form a multi-stage step-by-step filtration of the test solution, and particles of a specific size are removed step by step, and finally a higher purity filtrate is obtained, and finally the life of the filter material is extended. By removing larger particles first, the subsequent filter material is not easy to be blocked, thereby reducing the replacement frequency.

The drive motor 43 is fixedly arranged at the bottom of the second connecting plate 12. The drive motor 43 will only very slowly drive the filter buckets on the two supporting assemblies to rotate slowly, so that the test solution is slowly and evenly introduced into various places on the surface of the bucket-shaped filter paper, thereby making full use of the filter paper.

[0046] The closed avoidance component includes a servo motor 29, a closed cylinder 23, an extension rod 24, a closed head 25, a top support plate 22, a mounting plate 28, a micro switch 27, and a trigger rod 26. The mounting plate 28 is fixedly arranged on the rear side of the vertical plate 9, and a micro switch 27 is fixedly arranged on the top of the mounting plate 28. The servo motor 29 is vertically fixedly arranged on the top of the stage 1. The output end of the servo motor 29 is fixedly arranged with a top support plate 22, and the top of the top support plate 22 is fixedly arranged with a closed cylinder 23.

The closed head 25 is a stepped head, and the material is selected to be rubber material. The diameter of the narrow section of the closed head 25 is slightly larger than the top opening diameter of the distillation flask 61.

[0047] A trigger rod 26 is fixedly provided on the outer wall of the output end of the servo motor 29, and the end of the trigger rod 26 contacts the side of the micro switch 27.

The closed cylinder 23, the drive motor 43, and the servo motor 29 are all connected to the controller 8.

[0048] The specific implementation steps and principles of the present invention are:

[0049] In the initial state, the extension rod 24 rotates to a position parallel to the vertical plate 9, and the closing head 25 is not directly above the top opening of the distillation flask 61. The worker introduces the liquid to be filtered and distilled into the liquid guide bucket 14, puts the filter bucket into the circular grooves 11 on the staggered first connecting plate 10 and the second connecting plate 12, puts the filter paper into the filter bucket, starts the common drive component, and opens the valve at the bottom of the liquid guide bucket 14. The drive motor 43 in the common drive component drives the two filter buckets placed on the support ring 46 to rotate through the top pulley 39, the short belt 40, the bottom pulley 42, and the long belt 44. The liquid to be processed is evenly poured on various places on the filter paper and filtered by the multi-stage filter buckets. The filtered liquid falls into the distillation flask 61.

[0050] The worker controls the closing avoidance assembly to close the opening of the distillation flask 61 through the controller 8. Specifically, the controller 8 first controls the servo motor 29 to rotate until the trigger rod 26 of the vertical section of the servo motor 29 presses the micro switch 27. At this time, the closing head 25 at the bottom of the extension rod 24 moves to the top of the distillation flask 61. At this time, the closing cylinder 23 can move, driving the closing head 25 to press into the top opening of the distillation flask 61, and then start the water bath 18. The water bath 18 distills the distillation flask 61. The gas distilled from the distillation flask 61 is cooled by the condenser 31 and finally flows back to the inside of the recovery cylinder 13.
