Description

Technical Field

[0001] The utility model belongs to the technical field of hose transfer pumps, and particularly relates to a hose assembly facilitating CIP / SIP (Cleaning in Place / Sterilization in Place). Background Art

[0002] At present, transfer pumps using hoses as carriers are widely used in the pharmaceutical field. In a pharmaceutical production environment with high production requirements, it is often necessary to clean and sterilize the hoses of hose transfer pumps. Since a hose pump mainly conveys fluids by squeezing the hose, if the online cleaning and sterilization effect of squeezing the hose is not good, it is usually necessary to disassemble the squeezing hose from the pump body for cleaning, sterilization and other operations. After sterilization, it is reinstalled into the pump body, which has defects such as troublesome operation, time-consuming and laborious, increasing the enterprise's labor cost and reducing work efficiency.

[0003] The joints connecting both ends of the existing hose transfer pump and the squeezing hose all adopt straight-through joints to ensure unobstructed fluid transmission. When performing online cleaning and sterilization, if the inner diameter of the squeezing hose is much larger than that of the transfer hoses at the filling needle end and the distributor end, due to the difference in the flow rate of the cleaning liquid in each section of the hose, the inner walls of the transfer hoses at the filling needle end and the distributor end can often be cleaned cleanly, but it is very difficult for the cleaning degree of the inner wall of the squeezing hose to reach the expected effect after cleaning. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to solve the problems of troublesome operation, time-consuming and laborious sterilization and cleaning of the existing squeezing hose, and unstable cleaning quality, etc., and provide a hose assembly facilitating CIP / SIP with a compact structure, convenient disassembly and assembly, high reliability, and conducive to improving the CIP / SIP effect of the inner wall of the squeezing hose.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A hose assembly facilitating CIP / SIP includes: a squeezing hose assembly, a three-way valve and a cleaning pipeline. The three-way valve includes at least three interfaces. The liquid inlet of the squeezing hose assembly is connected to a distributor through a liquid outlet pipeline of the distributor. The liquid outlet of the squeezing hose assembly is respectively connected to a filling needle liquid inlet pipeline and a cleaning pipeline through the three-way valve. The cleaning pipeline is connected to a high-temperature steam source, and a control valve is provided in the three-way valve. The control valve is used to control the on-off of the cleaning pipeline and the squeezing hose assembly; when the squeezing hose assembly performs fluid metering and filling, the control valve is in a closed state, and when the squeezing hose assembly performs CIP / SIP, the control valve is in an open state.

[0007] As a further improvement of the present utility model, the three-way valve includes a first interface, a second interface and a third interface. The first interface and the second interface are symmetrically arranged on two sides of the three-way valve. The third interface is perpendicular to the first interface, and the control valve is close to the third interface. The first interface is used to connect the liquid outlet of the extrusion hose assembly. The second interface is used to connect the liquid inlet pipeline of the filling needle. The third interface is used to connect the cleaning pipeline.

[0008] As a further improvement of the present utility model, the control valve is a diaphragm valve or a pneumatic valve.

[0009] As a further improvement of the present utility model, the extrusion hose assembly includes a first reducing joint, a second reducing joint and an extrusion hose. The liquid inlet of the extrusion hose is connected to the liquid outlet pipeline of the liquid distributor through the first reducing joint, and the liquid outlet of the extrusion hose is connected to the first interface through the second reducing joint.

[0010] As a further improvement of the present utility model, the inner diameters of the liquid outlet pipeline of the liquid distributor, the liquid inlet pipeline of the filling needle and the cleaning pipeline are all smaller than the inner diameter of the extrusion hose.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] The hose assembly of the present utility model facilitating CIP / SIP is such that the liquid outlet of the extrusion hose assembly is respectively connected to the liquid inlet pipeline of the filling needle and the cleaning pipeline through a three-way valve. Through the cleaning pipeline, the extrusion hose assembly is connected to a high-temperature steam source, providing conditions for CIP / SIP of the extrusion hose assembly. Meanwhile, a control valve is provided in the three-way valve to control the on-off of the cleaning pipeline and the extrusion hose assembly. When the extrusion hose assembly is performing fluid metering and filling, the control valve is in the closed state, which will not affect the normal fluid filling of the hose transfer pump at all. When the extrusion hose assembly is performing CIP / SIP, the control valve is in the open state, and high-temperature steam enters the inside of the extrusion hose assembly through the cleaning pipeline for cleaning and sterilization. Further, the opening degree of the control valve can be adjusted to reduce the flow rate of the fluid in the liquid inlet pipeline of the filling needle and appropriately extend the CIP / SIP time, which can not only clean the inner wall of the hose at the filling needle end well, but also improve the cleaning effect of the inner wall of the extrusion hose. It is simple and practical. The present utility model well solves the problem that the CIP / SIP of the filling system in the current pharmaceutical industry and even the entire fluid filling industry has a major quality risk due to insufficient flow rate resulting in incomplete cleaning.

[0018] Embodiment

[0019] As Figure 1 shown, the hose assembly facilitating CIP / SIP of the present invention includes: an extrusion hose assembly, a three-way valve 5 and a cleaning pipeline 8. The liquid inlet of the extrusion hose assembly is connected to the liquid distributor 1 through the liquid outlet pipeline 2 of the liquid distributor. The liquid outlet of the extrusion hose assembly is respectively connected to the liquid inlet pipeline 6 of the filling needle and the cleaning pipeline 8 through the three-way valve 5. The liquid inlet pipeline 6 of the filling needle is connected to the filling needle 7, and the cleaning pipeline 8 is connected to a high-temperature steam source (not shown in the figure). And a control valve 9 is provided in the three-way valve 5, and the control valve 9 is used to control the on-off of the cleaning pipeline 8 and the extrusion hose assembly. When the extrusion hose assembly performs fluid metering and filling, the control valve 9 is in the closed state. When the extrusion hose assembly performs CIP / SIP, the control valve 9 is in the open state. Further, the control valve 9 adopts a diaphragm valve, with a simple structure and precise control. In other embodiments, the control valve 9 can also adopt a pneumatic valve.

[0020] In this embodiment, the liquid outlet of the extrusion hose assembly is connected to the filling needle liquid inlet pipeline 6 and the cleaning pipeline 8 respectively through a three-way valve 5. By means of the cleaning pipeline 8, the extrusion hose assembly is connected to a high-temperature steam source, providing conditions for CIP / SIP of the extrusion hose assembly. Meanwhile, a control valve 9 is provided in the three-way valve 5 to control the on-off of the cleaning pipeline 8 and the extrusion hose assembly. When the extrusion hose assembly performs fluid metering and filling, the control valve 9 is in a closed state, which will not affect the normal fluid filling of the hose transfer pump at all. When the extrusion hose assembly performs CIP / SIP, the control valve 9 is in an open state, and high-temperature steam enters the inside of the extrusion hose assembly through the cleaning pipeline 8 for cleaning and sterilization. Further, the opening degree of the control valve 9 can be adjusted to reduce the flow rate of the fluid in the filling needle liquid inlet pipeline 6 and appropriately extend the CIP / SIP time, which can not only clean the inner wall of the filling needle end hose well, but also improve the cleaning effect of the inner wall of the extrusion hose, which is simple and practical.

[0021] As Figure 1 shown, the three-way valve 5 includes a first interface 51, a second interface 52 and a third interface 53. The first interface 51 and the second interface 52 are symmetrically arranged on two sides of the three-way valve 5. The third interface 53 is perpendicular to the first interface 51, and the control valve 9 is close to the third interface 53. The first interface 51 is used to connect the liquid outlet of the extrusion hose assembly. The second interface 52 is used to connect the filling needle liquid inlet pipeline 6 to ensure smooth fluid filling. The third interface 53 is used to connect the cleaning pipeline 8.

[0022] As Figure 1 shown, the extrusion hose assembly includes a first reducing joint 31, a second reducing joint 32 and an extrusion hose 4. The liquid inlet of the extrusion hose 4 is connected to the liquid outlet pipeline 2 of the liquid distributor through the first reducing joint 31, and the liquid outlet of the extrusion hose 4 is connected to the first interface 51 through the second reducing joint 32.

[0023] Further, the liquid outlet pipeline 2 of the liquid distributor, the filling needle liquid inlet pipeline 6 and the cleaning pipeline 8 have the same inner diameter, and the inner diameters of the liquid outlet pipeline 2 of the liquid distributor, the filling needle liquid inlet pipeline 6 and the cleaning pipeline 8 are all smaller than the inner diameter of the extrusion hose 4. It can be understood that when the inner diameter of the extrusion hose 4 is three times or more of the inner diameters of the liquid outlet pipeline 2 of the liquid distributor and the filling needle liquid inlet pipeline 6, the three-way valve 5 can be designed and manufactured as a four-way joint to connect two cleaning hoses 8 to increase the input amount of high-temperature steam and ensure the cleaning quality of the inner walls of the extrusion hose 4 and the filling needle liquid inlet pipeline 6. During actual use, a multi-way joint with a control valve can be designed and manufactured according to the sizes determined by the inner diameters of each hose, which can not only ensure the quality of on-line cleaning and sterilization of the inner walls of the hoses, but also control the economic cost.

[0024] The hose assembly facilitating CIP / SIP of the present utility model replaces the straight-through joint connecting the extrusion hose 4 and the filling needle liquid inlet pipeline 6 in the existing filling system with a three-way valve 5 with a control valve 9. After replacing it with the three-way valve 5 with a control valve 9, it not only does not affect the normal fluid filling of the hose transfer pump, but also can improve the cleaning effect of the inner wall of the extrusion hose during CIP / SIP. It is simple and practical, and well solves the problem of major quality risks existing in the filling system CIP / SIP of the current pharmaceutical industry and even the entire fluid filling industry due to insufficient flow rate resulting in incomplete cleaning.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the methods and technical contents disclosed above, or modify it into equivalent embodiments with equivalent changes. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model still fall within the scope of protection of the technical solution of the present utility model.
