Description

Technical Field

[0001] The utility model relates to the technical field of food and drug packaging, and particularly relates to a multi-distribution branch pipe cleaning system. Background Art

[0002] In the production process of vaccine bulk solution, a large number of bioreactors are often involved. The distribution and supply of materials and the design of the pipeline system for harvest liquid / waste liquid are very complex, and multiple distribution pipelines need to be cleaned simultaneously. For this reason, the common cleaning scheme for the distribution pipeline is that the cleaning branch pipes of all distribution pipelines in a room are directly connected to the same discharge main pipe, and a detection component is arranged at the end of each branch pipe to judge whether the cleaning end point is reached. The disadvantage of this scheme is that there are generally dozens to hundreds of distribution pipelines for vaccine bulk solution. If a set of detection components is equipped for each distribution pipeline separately, the equipment cost is very high, and there is easily residual cleaning lye in the main pipe between the distribution pipelines, which will affect subsequent detection and requires additional separate cleaning, increasing the cleaning water consumption and cleaning time. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a multi-distribution branch pipe cleaning system with fast flushing speed, less residual flushing liquid and low cost.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme:

[0005] A multi-distribution branch pipe cleaning system includes a second drainage main pipe. Multiple distribution branch pipes are respectively communicated with the second drainage main pipe through sterilization pipelines. A first isolation valve is arranged on the sterilization pipeline. The system also includes a first drainage main pipe. One end of the first drainage main pipe is provided with a first valve, and the other end is provided with a second valve. The water outlets of multiple distribution branch pipes are all communicated with the first drainage main pipe and are all located between the first valve and the second valve. A conductivity detection piece for detecting whether each distribution branch pipe is cleaned is arranged on the side of the first valve far away from the distribution branch pipes. One end of the first drainage main pipe is communicated with the second drainage main pipe.

[0006] As a further improvement of the above technical scheme:

[0007] The second drainage main pipe is communicated with one end of the first drainage main pipe close to the second valve.

[0008] The second drainage main pipe and the first drainage main pipe are arranged in parallel.

[0009] The first isolation valve is arranged close to the second drainage main pipe.

[0010] A second isolation valve is arranged on each distribution branch pipe. The second isolation valve is used to control the on-off with the first drainage main pipe, and the second isolation valve and the first isolation valve are arranged in parallel.

[0011] The second isolation valve is arranged close to the first main drainage pipe.

[0012] Each of the distribution branch pipes is arranged perpendicular to the first main drainage pipe.

[0013] The first valve is arranged close to the distribution branch pipe.

[0014] The second valve is arranged close to the distribution branch pipe.

[0015] A cleaning method for the above multi-distribution branch pipe cleaning system

[0016] The first isolation valve remains closed, and it is judged whether the water outlet of the distribution branch pipe is closer to the first valve or the second valve;

[0017] If it is closer to the first valve, open the first valve, close the second valve, and rinse the distribution branch pipe with purified water and cleaning alkaline water in sequence. The rinsing water flows out from the direction of the first valve; then close the first valve, open the second valve, purge the distribution branch pipe, and blow the residual alkaline cleaning solution between the first valve and the second valve out in the direction of the second valve; finally, open the first valve, close the second valve, and rinse the distribution branch pipe with purified water and injection water until the conductivity detector shows qualified.

[0018] If it is closer to the second valve, close the first valve, open the second valve, and rinse the distribution branch pipe with purified water and cleaning alkaline water in sequence. The rinsing water flows out from the direction of the second valve; then open the first valve, close the second valve, purge the distribution branch pipe, and blow the residual alkaline cleaning solution between the first valve and the second valve out in the direction of the first valve; finally, rinse the distribution branch pipe with purified water and injection water until the conductivity detector shows qualified.

[0019] Clean all the distribution branch pipes according to the above method.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] The multi-distribution branch pipe cleaning system disclosed by the present utility model has the water outlets of each distribution branch pipe communicated with the same first drainage main pipe. A first valve and a second valve are arranged at both ends of the first drainage main pipe. During cleaning, it is judged which valve is closer to the water outlet of the distribution branch pipe. The closer valve is opened and the farther valve is closed for flushing with purified water and cleaning alkaline water. The path for the flushing water to flow out is shorter, which can accelerate the flushing speed. However, after the flushing is completed, there will be residual flushing liquid between the two valves. At this time, the closer valve is closed and the farther valve is opened to blow out the residual flushing liquid between the two valves in the reverse direction, saving the consumption of subsequent purified water and injection water and the cleaning time. Finally, the second valve is closed and the first valve is opened to flush the distribution branch pipe with purified water and injection water until the conductivity detection component shows qualified. There is no need to drain according to the distance, so that all distribution branch pipes can be detected whether they are cleaned cleanly with a set of conductivity detection components, saving the equipment cost required for detection. In addition, the first drainage main pipe is communicated with the second drainage main pipe 6 for draining water in the subsequent sterilization step of the distribution branch pipe, and one drainage end can be set less, and the structure is more compact.

[0022] The cleaning method of the multi-distribution branch pipe cleaning system disclosed by the present utility model has a shorter path for the flushing water to flow out, a fast flushing speed, and at the same time blows the flushing liquid in the reverse direction to reduce the residue of the flushing liquid between the two valves, saving the consumption of subsequent purified water and injection water and the cleaning time. Finally, all distribution branch pipes can be detected with a set of conductivity detection components, and the cost is low. Description of the Drawings

[0029] Embodiment 1

[0030] Figure 1 An embodiment of the present utility model is shown. The multi-distribution branch pipe cleaning system of this embodiment includes a second drainage main pipe 6. A plurality of distribution branch pipes 4 are respectively communicated with the second drainage main pipe 6 through sterilization pipelines 7. A first isolation valve 42 is provided on the sterilization pipeline 7. It further includes a first drainage main pipe 1. One end of the first drainage main pipe 1 is provided with a first valve 2, and the other end is provided with a second valve 3. The water outlets of the plurality of distribution branch pipes 4 are all communicated with the first drainage main pipe 1 and are all located between the first valve 2 and the second valve 3. A conductivity detection member 5 for detecting whether each distribution branch pipe 4 is cleaned is provided on the side of the first valve 2 away from the distribution branch pipe 4. One end of the first drainage main pipe 1 is communicated with the second drainage main pipe 6.

[0031] The specific cleaning method of this multi-distribution branch pipe cleaning system is as follows: 1) Keep the first isolation valve 42 closed, and determine whether the water outlet of the distribution branch pipe 4 is closer to the first valve 2 or the second valve 3; 2) If it is closer to the first valve 2, open the first valve 2, close the second valve 3, and rinse the distribution branch pipe 4 with purified water and cleaning alkaline water in sequence. The rinsing water flows out from the direction of the first valve 2; then close the first valve 2, open the second valve 3, purge the distribution branch pipe 4, and blow the residual alkaline cleaning solution between the first valve 2 and the second valve 3 out in the direction of the second valve 3; finally, open the first valve 2, close the second valve 3, and rinse the distribution branch pipe 4 with purified water and injection water until the conductivity detector 5 shows qualified; if it is closer to the second valve 3, close the first valve 2, open the second valve 3, and rinse the distribution branch pipe 4 with purified water and cleaning alkaline water in sequence. The rinsing water flows out from the direction of the second valve 3; then open the first valve 2, close the second valve 3, purge the distribution branch pipe 4, and blow the residual alkaline cleaning solution between the first valve 2 and the second valve 3 out in the direction of the first valve 2; finally, rinse the distribution branch pipe 4 with purified water and injection water until the conductivity detector 5 shows qualified; 3) Repeat the above method until all distribution branch pipes 4 are cleaned.

[0032] For this multi-distribution branch pipe cleaning system, the water outlets of all distribution branch pipes 4 are connected to the same first drainage main pipe 1. A first valve 2 and a second valve 3 are arranged at both ends of the first drainage main pipe 1. During cleaning, determine which valve is closer to the water outlet of the distribution branch pipe 4, open the closer valve, close the farther valve, and conduct rinsing with purified water and cleaning alkaline water. The path of the rinsing water flowing out is shorter, which can accelerate the rinsing speed. However, after rinsing, there will be residual rinsing liquid between the two valves. At this time, close the closer valve, open the farther valve, and blow the residual rinsing liquid between the two valves out in the reverse direction, saving the usage amount of subsequent purified water and injection water and the cleaning time. Finally, close the second valve 3, open the first valve 2, and rinse the distribution branch pipe 4 with purified water and injection water until the conductivity detector 5 shows qualified. There is no need to drain according to the distance, so that a set of conductivity detector 5 can be used to detect whether all distribution branch pipes 4 are cleaned, saving the equipment cost required for detection. In addition, the first drainage main pipe 1 is connected to the second drainage main pipe 6 for draining in the subsequent sterilization step of the distribution branch pipe 4, so that one less drainage end can be set, and the structure is more compact.

[0033] In this embodiment, the second drainage main pipe 6 is connected to one end of the first drainage main pipe 1 close to the second valve 3. The outflow paths of purified water and injection water are shorter and the efficiency is higher.

[0034] In this embodiment, the second drainage main pipe 6 is arranged in parallel with the first drainage main pipe 1. The structure is compact and beautiful.

[0035] In this embodiment, the first isolation valve 42 is arranged close to the second drainage main pipe 6, reducing the residual distance of the caustic cleaning solution between the first isolation valve 42 and the second drainage main pipe 6.

[0036] In this embodiment, a second isolation valve 41 is provided on each distribution branch pipe 4. The second isolation valve 41 is used to control the on-off with the first drainage main pipe 1, and the second isolation valve 41 and the first isolation valve 42 are arranged in parallel. The second isolation valve 41 is used to control the cleaning of the distribution branch pipe 4, and the first isolation valve 42 controls the sterilization of the distribution branch pipe 4. Further preferably, a master control valve 8 is provided at the front end of the first isolation valve 42 and the second isolation valve 41 on the distribution branch pipe 4 to control the on-off of the distribution branch pipe 4.

[0037] In this embodiment, the second isolation valve 41 is arranged close to the first drainage main pipe 1, reducing the residual distance of the caustic cleaning solution between the second isolation valve 41 and the first drainage main pipe 1.

[0038] In this embodiment, each distribution branch pipe 4 is arranged perpendicular to the first drainage main pipe 1, with good flow effect and high speed.

[0039] In this embodiment, the first valve 2 is arranged close to the distribution branch pipe 4, reducing the residual distance of the caustic cleaning solution between the distribution branch pipe 4 and the first valve 2.

[0040] In this embodiment, the second valve 3 is arranged close to the distribution branch pipe 4, reducing the residual distance of the caustic cleaning solution between the distribution branch pipe 4 and the second valve 3.

[0044] If it is closer to the first valve 2, open the first valve 2 and close the second valve 3, and rinse the distribution branch pipe 4 with purified water and cleaning caustic water in sequence. The rinsing water flows out from the direction of the first valve 2; then close the first valve 2, open the second valve 3, and purge the distribution branch pipe 4 to blow the residual caustic cleaning solution between the first valve 2 and the second valve 3 out in the direction of the second valve 3; finally, open the first valve 2, close the second valve 3, and rinse the distribution branch pipe 4 with purified water and injection water until the conductivity detection component 5 shows qualified.

[0045] If it is closer to the second valve 3, close the first valve 2, open the second valve 3, and rinse the distribution branch pipe 4 with purified water and cleaning alkaline water in sequence.
