Fig. 2 is the structural representation of a kind of detailed description of the invention of sterilizing liquid dispensing device provided by the utility model.
Detailed description of the invention
Core of the present utility model is to provide a kind of sterilizing liquid dispensing device, effectively can get rid of the cold air in Agitation Tank before sterilization.
In order to make those skilled in the art person understand this utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 2, Fig. 2 is the structural representation of a kind of detailed description of the invention of sterilizing liquid dispensing device provided by the utility model.
In this embodiment, sterilizing liquid dispensing device comprises Agitation Tank 1, the pure steam conveying pipe 2 be communicated with Agitation Tank 1 and is arranged on the first pneumatic diaphragm valve 3 pure steam conveying pipe 2 entering Agitation Tank 1 for controlling pure steam, also comprise vacuum pump 4, for connect vacuum pump 4 and Agitation Tank 1 vacuum lead 5, be arranged on vacuum lead 5 for opening or close the second pneumatic diaphragm valve 6 of the evacuation action of Agitation Tank 1 and the pressure transducer 7 for detecting the force value in Agitation Tank 1.
When needs carry out sterilization treatment to Agitation Tank 1, first vacuum pump 4 is opened, then the second pneumatic diaphragm valve 6 is opened, vacuum pump 4 carries out evacuation by vacuum lead 5 pairs of Agitation Tanks 1, then pressure transducer 7 is utilized to detect force value in Agitation Tank 1, and judge that whether force value in Agitation Tank 1 is lower than preset pressure value, if, then close the second pneumatic diaphragm valve 6, open the first pneumatic diaphragm valve 3, in Agitation Tank 1, pass into pure steam, if not, then continue to carry out evacuation to Agitation Tank 1.Pass into pure steam again to after Agitation Tank 1 evacuation, effectively can reduce the residual quantity of the cold air in Agitation Tank 1.
In order to get rid of the cold air in Agitation Tank 1 more thoroughly, after pure steam can being passed into Agitation Tank 1, evacuation again, again pass into pure steam, for diluting the cold air in Agitation Tank 1, the process of evacuation can in triplicate, 99.99% cold air can found time after three evacuation in Agitation Tank 1, and the technology that repetition evacuation carries out sterilizing belongs to vacuum impulse sterilization technology.Here it should be noted that, three evacuation are enough to meet sterilizing demand, and more evacuation can cause waste.
This sterilizing liquid dispensing device is connected to the vacuum pipe network in factory in Agitation Tank 1, adds vacuum pump 4, vacuum lead 5, second pneumatic diaphragm valve 6 and the pressure transducer 7 for detecting the force value in Agitation Tank 1 compared to prior art.This device utilizes vacuum pump 4 to be extracted out by the cold air in Agitation Tank 1, after the force value in Agitation Tank 1 is lower than preset pressure value, namely after reaching certain vacuum in Agitation Tank 1, pure steam is passed in Agitation Tank 1, and then to after Agitation Tank 1 evacuation, again in Agitation Tank 1, pass into pure steam.This device effectively can get rid of the cold air in Agitation Tank 1, and pure steam can be covered on the tank skin of Agitation Tank 1 completely, eliminates sterilizing " dead angle ", meanwhile, in the pipeline be communicated with Agitation Tank 1, serves the effect of sterilizing equally.
Concrete, after the force value that pressure transducer 7 detects in Agitation Tank 1, can be artificial judge that whether force value in Agitation Tank 1 is lower than preset pressure value, and by setting up judgment means, artificial control first pneumatic diaphragm valve 3 and the unlatching of the second pneumatic diaphragm valve 6 or closedown, also can judge that whether force value in Agitation Tank 1 is lower than preset pressure value.In addition, judgment means is also for sending to the first pneumatic diaphragm valve 3 and the second pneumatic diaphragm valve 6, first pneumatic diaphragm valve 3 and the second pneumatic diaphragm valve 6 to open or closedown according to judged result by judged result.By setting up judgment means, without the need to artificially judging that the force value in Agitation Tank 1 reaches preset pressure value, automation mechanized operation can be realized.
On the other hand, for the ease of the installation of pressure transducer 7 and the reading of data, pressure transducer 7 can be arranged on the outer surface of Agitation Tank 1.The number of pressure transducer 7 can be one, can be multiple, draw the actual pressure value in Agitation Tank 1, making testing result more accurate by averaging.
Except above-mentioned setting, the bottom of Agitation Tank 1 is also provided with the magnetic stirring apparatus 8 for stirring medicinal liquid.After Agitation Tank 1 sterilizing, in Agitation Tank 1, add medicinal liquid, magnetic stirring apparatus 8 can accelerate the mixing speed of medicinal liquid, makes the stirring of medicinal liquid more even.In addition, after the medicinal liquid in Agitation Tank 1 machines, need the tank body proceeding to other, therefore the bottom of Agitation Tank 1 is also provided with the bottom valve 9 flowing into other tank bodies for controlling medicinal liquid.Open bottom valve 9, medicinal liquid just can flow out in Agitation Tank 1, after hygiene-type centrifugal pump and sterilizing filter, enters receiving tank and stores.Here it should be noted that, for other tank bodies in medicinal liquid system and pipeline, vacuum impulse sterilization technology can be adopted equally to carry out sterilizing.
Above sterilizing liquid dispensing device provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from this utility model principle, can also carry out some improvement and modification to this utility model, these improve and modify and also fall in the protection domain of this utility model claim.
