Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline blockage detection devices, specifically to a pipeline blockage detection device for a blow-fill-seal filling system. Background Technology
[0002] The filling pipeline of the BFS (Blow-Fill-Seal) filling system is quite complex, consisting entirely of stainless steel pipes that are quite long and have very fine inner diameters. Furthermore, the aseptic system cannot be compromised after production preparation, making it impossible to directly open the pipeline system for inspection. If a thorough internal inspection of the pipeline is not performed before production preparation, and foreign objects or other contaminants cause blockages, the production process will be halted, directly impacting drug quality. Therefore, a dedicated internal pipeline inspection device is needed to perform internal and anti-blockage checks on the filling pipeline during the BFS (Blow-Fill-Seal) filling system's production preparation phase, ensuring smooth production execution. Utility Model Content

[0009] In the aforementioned pipe blockage detection device for a blow-fill-seal filling system, the diameter of the guide cable is 1 mm.
[0010] The aforementioned pipe blockage detection device for a blow-fill-seal filling system includes a pressure sensor at the tail end of the pipe, which can detect that the guide cable has reached its farthest point for subsequent processing.
[0011] The aforementioned pipe blockage detection device for a blow-fill-seal filling system includes an object detector at the tail end of the pipe, which can detect when the guide cable has reached its furthest point, allowing for subsequent processing.
[0012] The aforementioned pipe blockage detection device for a blow-fill-seal filling system includes a laser sensor at the tail end of the pipe, which can detect that the guide cable has reached its farthest point for subsequent processing.

[0022] This utility model provides a pipeline blockage detection device for a blow-fill-seal filling system.

[0023] like Figure 1 As shown in the first embodiment, a pipe blockage detection device for a blow-fill-seal filling system includes a handle 100 and a guide cable 200. One end of the guide cable 200 is connected to and wrapped around the handle 100, and the other end of the guide cable 200 is inserted into the pipe 400 of the blow-fill-seal filling system 300. After the guide cable 200 is inserted into the pipe 400, it is gradually released by the handle 100 to extend continuously. If the pipe 400 is not blocked, the guide cable 200 will extend from the other end of the pipe 400. The head of the guide cable 200 can be directly viewed. If the pipe 400 is blocked, the guide cable 200 cannot be pushed any further, indicating that the pipe 400 is blocked.

[0025] The guide cable 200 is made of stainless steel, the same material as the inner wall of the pipe 400, so it will not rub off or fall off. This allows for blockage detection during the production preparation stage, thus avoiding the risk of blockage from being brought into the production process and effectively ensuring the quality of drug production. The diameter of the guide cable 200 is 1mm.
[0026] like Figure 1 As shown in the second embodiment, a pipe blockage detection device for a blow-fill-seal filling system includes a handle 100 and a guide cable 200. One end of the guide cable 200 is connected to and wrapped around the handle 100, and the other end of the guide cable 200 is inserted into the pipe 400 of the blow-fill-seal filling system 300. After the guide cable 200 is inserted into the pipe 400, it is gradually released by the handle 100 to extend continuously. If the pipe 400 is not blocked, the guide cable 200 will extend from the other end of the pipe 400. The head of the guide cable 200 can be directly viewed. If the pipe 400 is blocked, the guide cable 200 cannot be pushed any further, indicating that the pipe 400 is blocked.
[0027] The guide cable 200 is equipped with scale lines. The travel position of the guide cable 200 can be determined by the scale on the guide cable 200. The scale on the guide cable 200 will be used to determine the location of the blockage, which will facilitate further analysis and processing.
[0028] The outer wall of the guide cable 200 is made of stainless steel, the same material as the inner wall of the pipe 400, so there will be no friction or detachment. Thus, by conducting blockage detection in the production preparation stage, the risk of blockage can be avoided and brought into the production process, effectively ensuring the quality of drug production. The diameter of the guide cable 200 is 1mm.
[0029] The third embodiment differs from the first embodiment in that a pressure sensor is provided at the tail end of the pipe 400, which can detect that the guide cable 200 has reached the farthest end, so as to carry out subsequent processing.
[0030] The fourth embodiment differs from the first embodiment in that an object detector is provided at the tail end of the pipe 400, which can detect that the guide cable 200 has reached the farthest end so that subsequent processing can be carried out.
