Detailed Implementation

[0020] As a core piece of equipment for material mixing and preparation, pharmaceutical solution preparation tanks often require multiple tanks with different functions to meet diverse needs such as raw material mixing, reaction, and storage, depending on the complex production process. The connections between these tanks and to material conveying pipelines typically rely on independent pipes, valves, and other components. However, this current connection method necessitates the laying of numerous independent pipelines, increasing costs and hindering subsequent maintenance.

[0021] To address the aforementioned issues, existing technologies have proposed pipeline conversion devices that integrate all tank and pipeline interfaces onto a conversion plate. During use, the interfaces that need to be connected are linked one-to-one via adapter pipes, and the adapter pipes are removed when not in use.

[0022] However, the above technical solutions still have problems such as the lack of a fixed place for the transfer pipe after dismantling. Operators usually place it on the ground or on the equipment pipeline, which can easily lead to contamination of the connecting pipe and other technical issues such as difficulty in finding it.

[0023] To address the aforementioned problems, this invention provides a pipeline conversion device and a liquid preparation tank system, which simplifies pipeline connections, thereby reducing costs and facilitating maintenance. Most importantly, by installing a fixing bracket, the connecting pipe can be fixed to the bracket after removal, facilitating pipe management and reducing the risk of contamination.

[0034] This embodiment includes a frame 110, a conversion plate 120, a fixing bracket 130, multiple first connectors 140, multiple second connectors 150, multiple third connectors 160, and multiple connecting pipes 170. The conversion plate 120 has multiple mounting holes 121, into which the first connectors 140, second connectors 150, and third connectors 160 are installed one-to-one. In use, one end of the first connector 140 is connected to the delivery pipe 230, one end of the second connector 150 is connected to a preparation tank via a pipe, and one end of the third connector 160 is connected to another preparation tank via a pipe.

[0040] Please refer to Figures 1 to 4 Furthermore, the connecting beam 131 includes a horizontal section 133 and a vertical section 134 that connect vertically. The vertical section 134 is connected to the conversion plate 120, and the snap-fit ​​seat 132 is connected to the horizontal section 133.

[0041] In this embodiment, the connecting beam 131 is configured to vertically connect the horizontal section 133 and the vertical section 134, which can improve the load-bearing capacity.

[0042] Furthermore, the connecting beam 131 can be a "T" shape rotated 90° clockwise or an "L" shape rotated 90° counterclockwise. The horizontal section 133 can be connected to the conversion plate 120 by welding. The snap-fit ​​seat 132 can be fixed to the upper surface of the horizontal section 133 by screws.

[0043] Furthermore, the snap-fit ​​seat 132 includes a seat body 135, the seat body 135 is provided with a snap-fit ​​groove 136 corresponding to the size of the connecting tube 170, the snap-fit ​​groove 136 has a notch 137, and the connecting tube 170 can be snapped into the snap-fit ​​groove 136 through the notch 137.

[0044] In this embodiment, by setting the snap-fit ​​socket 132 to the above structure, the snap-fit ​​fixing of the connecting pipe 170 can be made more convenient.

[0045] Furthermore, the first joint 140, the second joint 150, and the third joint 160 are all flange joints. Flange clamps 171 are connected to both ends of the connecting pipe 170, and both ends of the connecting pipe 170 can be connected to two of the first joint 140, the second joint 150, and the third joint 160 via the flange clamps 171.

[0046] In this embodiment, the first connector 140, the second connector 150, and the third connector 160 are all set as flange connectors, and flange clamps 171 are connected to both ends of the connecting pipe 170. Thus, the connecting pipe 170 can be easily connected to any two of the first connector 140, the second connector 150, and the third connector 160 through the flange clamps 171.

[0047] Please refer to Figures 1 to 4 In this embodiment, the first connector 140, the second connector 150 and the third connector 160 are arranged in a row, and the first connector 140 is located between the second connector 150 and the third connector 160.
