[0002] Vacuum tanks for pharmaceutical intermediates, as specialized equipment used for vacuum operations (pressure reduction and vacuuming) in pharmaceutical and chemical production, play a crucial role in the synthesis, separation, purification, and drying processes of pharmaceutical intermediates.

[0003] In traditional vacuum tanks, the connecting pipe is a crucial component, primarily responsible for ensuring material input and achieving gas vacuum. In existing technologies, the connection between the pipe and the tank body mainly relies on flange bolts for fixation. However, this fixing method has significant drawbacks. Since multiple bolts need to be tightened when connecting flanges, to prevent the gaskets at the connection points of the two flanges from twisting and deforming, the bolts at opposite corners are usually tightened first. The entire installation process is extremely cumbersome, time-consuming, and labor-intensive. Utility Model Content

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein.

[0023] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0024] A pharmaceutical intermediate vacuum tank includes a tank body 1, a connecting component 2 is installed on the surface of the tank body 1, a flange 3 is slidably connected inside the connecting component 2, and a connecting pipe 4 is fixedly connected to the surface of the flange 3.

[0025] The connecting assembly 2 includes a fixed tube 21 fixedly connected to the surface of the tank 1. The fixed tube 21 is connected to the interior of the tank 1. A fixed seat 22 is fixedly connected to the end of the fixed tube 21 away from the tank 1. A connecting groove 23 and a slot 25 are provided at the center of the interior of the fixed seat 22. The connecting groove 23 and the slot 25 are connected. The diameter of the slot 25 is larger than the diameter of the connecting groove 23. An annular silicone pad 24 is fixedly connected to the inner wall of the slot 25 near the connecting groove 23. A rotating groove 26 is provided at equal intervals inside the fixed seat 22. A gear 28 is rotatably connected inside the rotating groove 26. A stop plate 29 is fixedly connected to the surface of the gear 28. A toothed plate 27 is meshed with the surface of the gear 28. The toothed plate 27 is slidably connected inside the fixed seat 22. A connecting plate 210 is fixedly connected to the end face of the toothed plate 27. A fixed rod 211 is inserted through the interior of the connecting plate 210. A rotating ring 212 is threadedly connected to the outer surface of the fixed seat 22. The rotating ring 212 is hexagonal. Furthermore, an axial guide groove is provided on the inner wall of the fixed base 22, and the toothed plate 27 is slidably disposed in the guide groove.

[0026] In this embodiment, by installing flange 3 and inserting it into slot 25, rotating rotating ring 212 clockwise causes connecting plate 210 and toothed plate 27 to slide via arc block 2101. Through the meshing of toothed plate 27 and gear 28, all abutment plates 29 can be rotated, and pressure is applied to multiple points on the surface of flange 3 simultaneously. This allows flange 3 to be quickly and securely connected to fixed seat 22, with good sealing performance after connection. This method is more efficient than traditional bolt connection and significantly improves assembly efficiency.

[0027] Specifically, a second protective tube 2124 is fixedly connected to the surface of the rotating ring 212 near the fixed tube 21, and a first protective tube 2122 is fixedly connected to the surface of the rotating ring 212 away from the second protective tube 2124. A threaded hole 2121 is formed on the inner wall of the rotating ring 212, and a threaded groove matching the threaded hole 2121 is provided on the outer surface of the fixed seat 22. An arc-shaped block 2101 is fixedly connected to the end face of the connecting plate 210 away from the toothed plate 27. Steel balls 2102 are equidistantly installed inside the arc-shaped block 2101. An annular groove 2123 is formed on the surface of the rotating ring 212, and the outer surface of the arc-shaped block 2101 is slidably connected to the inside of the annular groove 2123. In this embodiment, the cross-section of the annular groove 2123 is "T" shaped.

[0028] In this embodiment, by setting a second protective tube 2124 and a first protective tube 2122, when the rotating ring 212 rotates, the second protective tube 2124 and the first protective tube 2122 can slide, which can protect the threaded connection between the threaded hole 2121 and the outer surface of the fixed seat 22. This can effectively prevent external dust and debris from falling into the threaded connection, avoid aging and corrosion problems caused by the accumulation of dust and debris, thereby extending the service life of the threaded connection, reducing the frequency of equipment maintenance and replacement of parts, and reducing maintenance costs.

[0029] Specifically, the steel ball 2102 protrudes from the arc-shaped block 2101, and the surface of the steel ball 2102 is rolledly connected to the inner wall of the annular groove 2123.

[0030] In this embodiment, by setting steel balls 2102, the friction between the arc block 2101 and the rotating ring 212 can be reduced, the service life of the arc block 2101 and the rotating ring 212 can be extended, and the stability of the sliding of the connecting plate 210 can be guaranteed.

[0031] Specifically, the fixed base 22 has an annular groove inside, and the outer surfaces of the second protective tube 2124 and the first protective tube 2122 are slidably connected inside the annular groove.

[0032] In this embodiment, by setting an annular groove, when the rotating ring 212 is rotated, the outer surfaces of the second protective tube 2124 and the first protective tube 2122 can be slidably connected inside the annular groove, ensuring the normal rotation of the rotating ring 212.

[0033] Specifically, the connecting plate 210 is "L" shaped, the inside of the fixing seat 22 is provided with a sliding groove, both ends of the fixing rod 211 are fixedly connected to the inside of the sliding groove, and the outer surface of the connecting plate 210 is slidably connected to the inside of the sliding groove.

[0034] In this embodiment, by setting a fixing rod 211, the stability of the sliding of the connecting plate 210 can be guaranteed.

[0035] Specifically, the outer surface of the flange 3 is slidably connected to the inside of the slot 25, the surface of the flange 3 is sealed against the surface of the annular silicone pad 24, the surface of the abutment 29 away from the gear 28 is arc-shaped, and the arc-shaped surface of the abutment 29 abuts against the surface of the flange 3.

[0036] In this embodiment, the flange 3 can be sealed and adhered to the surface of the annular silicone gasket 24 by the abutment plate 29 abutting against the flange 3.

[0037] The working principle and usage process of this utility model are as follows: When disassembling the connecting pipe 4, the rotating ring 212 is rotated counterclockwise by a wrench. The rotating ring 212 drives the connecting plate 210 and the toothed plate 27 to slide through the arc block 2101. Through the meshing of the toothed plate 27 and the gear 28, the abutment plate 29 is driven to rotate, so that the surface of the abutment plate 29 is away from the surface of the flange 3. When the abutment plate 29 is completely rotated into the rotating groove 26, the flange 3 can be directly removed from the slot 25 through the connecting pipe 4. At this time, the disassembly of the connecting pipe 4 is completed.

[0038] When assembling the connecting pipe 4, insert the flange 3 into the slot 25, and then rotate the rotating ring 212 clockwise with a wrench. The rotating ring 212 drives the toothed plate 27 to slide in the opposite direction through the arc block 2101 and the connecting plate 210. The toothed plate 27 and the gear 28 mesh with each other, driving the gear 28 and the abutment plate 29 to rotate in the opposite direction until the surface of the abutment plate 29 abuts against the surface of the flange 3. At this time, the flange 3 is sealed and fixedly connected to the slot 25 through the annular silicone gasket 24. At this time, the connecting pipe 4 and the tank 1 are assembled.

[0039] When the rotating ring 212 rotates, it can drive the second protective tube 2124 and the first protective tube 2122 to slide, which can protect the threaded connection between the threaded hole 2121 and the outer surface of the fixed seat 22. It can effectively prevent external dust and debris from falling into the threaded connection, avoid aging and corrosion problems caused by the accumulation of dust and debris, thereby extending the service life of the threaded connection, reducing the frequency of equipment maintenance and replacement of parts, and reducing maintenance costs.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
