Description

Technical Field

[0001] The utility model relates to the technical field of food and medicine packaging, in particular to an isolator cleaning system. Background Art

[0002] The existing isolator cleaning includes two parts: cleaning the cavity with a cleaning gun and cleaning the air duct. The cavity cleaning can be used in sequence, with inactivation liquid, injection water, and inactivation liquid for cleaning the cavity. The air duct cleaning is to use inactivation liquid, injection water, and compressed air to clean the isolator vertical air duct and the isolator horizontal air duct.

[0003] However, the following three problems are prone to occur in the entire process:

[0004] 1) After production, some isolators only use a cleaning gun to clean the inside of the cavity, and the air duct is cleaned once every half a month. When the cleaning gun cleans the cavity, the entire pipeline (including the pipeline cleaned by the air duct) will be filled with residual liquid, which will lead to bacterial growth in the long run and seriously cause the pipeline to rust.

[0005] 2) Since the cleaning time of a single pipeline is about 30 seconds, if the entire cleaning pipeline is long and the pipeline is empty at the beginning of cleaning, it is unreasonable to arbitrarily inactivate and clean multiple groups of pipelines. Only when the pipeline is filled with liquid can the spray cleaning pressure flow achieve the cleaning effect.

[0006] 3) Air purging of the pipeline may result in incomplete purging of the pipeline and the breeding of bacteria.

[0007] 4) After gas purge, the surface humidity inside the cavity, the air duct and the cleaning pipeline is high and cannot meet the drying requirements. Utility Model Content

[0008] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an isolator cleaning system in which an isolator cavity and an air duct assembly can be cleaned separately, thereby reducing the residual cleaning liquid in the air duct when cleaning the isolator cavity and reducing the growth of bacteria.

The isolator cleaning system of this embodiment includes a first cleaning medium input pipe 1 and a second cleaning medium input pipe 2. The first cleaning medium input pipe 1 is connected to a plurality of first cleaning pipes 11.

[0031] The isolator cleaning system is separately provided with a first cleaning medium input pipe 1 and a second cleaning medium input pipe 2, wherein the first cleaning medium input pipe 1 extends into each corresponding isolator cavity 3 through each first cleaning pipe 11 to clean the isolator cavity 3, and the second cleaning medium input pipe 2 is connected to the corresponding air duct assembly 4 through each second cleaning pipe 21 to clean the air duct assembly 4, and the first cleaning medium input pipe 1 is provided with a first switch valve 12, and the second cleaning medium input pipe 2 is provided with a second switch valve, so no matter whether the inlets of the first cleaning medium input pipe 1 and the second cleaning medium input pipe 2 are connected to the same set of cleaning media, the isolator cavity 3 and the air duct assembly 4 can be cleaned separately, and when cleaning the isolator cavity 3, the residual cleaning liquid will not enter the air duct assembly 4 and the second cleaning pipe 21, thereby reducing the growth of bacteria in the air duct assembly 4 and the second cleaning pipe 21.

[0032] In the present embodiment, the entrances of the first cleaning medium input pipe 1 and the second cleaning medium input pipe 2 are all connected with the inactivation liquid input pipe 5, the injection water input pipe 6 and the compressed air input pipe 7. The same inactivation liquid input pipe 5, the injection water input pipe 6 and the compressed air input pipe 7 are shared to carry out the input of each cleaning medium, and the equipment cost is low. Certainly, in other embodiments, the first cleaning medium input pipe 1 and the second cleaning medium input pipe 2 also can be connected with an inactivation liquid input pipe 5, the injection water input pipe 6 and the compressed air input pipe 7 respectively.

[0033] In this embodiment, the first switch valve 12 is arranged near the inlet of the first cleaning medium input pipe 1, and the second switch valve 22 is arranged near the inlet of the second cleaning medium input pipe 2. When the cleaning medium is input through the first cleaning medium input pipe 1 to clean the isolator cavity 3, the residual cleaning medium in the second cleaning medium input pipe 2 is reduced, and when the cleaning medium is input through the second cleaning medium input pipe 2 to clean the air duct assembly 4, the residual cleaning medium in the first cleaning medium input pipe 1 is reduced.

[0034] In this embodiment, the third switch valve 51, the fourth switch valve 61 and the fifth switch valve 71 are respectively provided on the inactivation liquid input pipe 5, the injection water input pipe 6 and the compressed air input pipe 7. The fire extinguishing liquid, the injection water and the compressed air are respectively controlled to enter the first cleaning medium input pipe 1 and / or the second cleaning medium input pipe 2 through the third switch valve 51, the fourth switch valve 61 and the fifth switch valve 71.

[0036] In this embodiment, the air duct assembly 4 includes a horizontal air duct 41 and a vertical air duct 42, and the second cleaning pipe 21 includes a horizontal air duct cleaning pipe 211 and a vertical air duct cleaning pipe 212. The horizontal air duct 41 and the vertical air duct 42 are respectively connected to the second cleaning medium input pipe 2 through the horizontal air duct cleaning pipe 211 and the vertical air duct cleaning pipe 212. The cleaning medium is input from the second cleaning medium input pipe 2, and then the horizontal air duct 41 is cleaned through the horizontal air duct cleaning pipe 211, and the vertical air duct 42 is cleaned through the vertical air duct cleaning pipe 212.

[0037] In this embodiment, a sixth switch valve 213 is provided on the horizontal air duct cleaning pipe 211, and a seventh switch valve 214 is provided on the vertical air duct cleaning pipe 212.

[0038] In this embodiment, the sixth switch valve 213 is disposed near the inlet of the horizontal air duct cleaning pipe 211, and the seventh switch valve 214 is disposed near the inlet of the vertical air duct cleaning pipe 212.
