The working principle is as follows:
power-on start-up
Selecting a mode
Join in marriage under the liquid mode-input liquid distribution volume (the unit adopts L or people) as 200L, the solenoid valve 6 of inlet channel 4 department is opened automatically to the system, ultrasonic flowmeter 5 begins to calculate the inflow, reverse osmosis water gets into in the bucket through inlet channel 4, when the inflow reaches 1/2 of the liquid distribution volume of settlement, close the solenoid valve 6 of inlet channel 4 department, the suggestion adds the concentrated powder of dialysis of corresponding volume, add the concentrated powder of dialysis from feed inlet 3 and join in marriage liquid bucket 1, temperature sensor 16 and force (forcing) pump 20 carry out next work this moment:
the temperature control system works: the temperature sensor 16 monitors the water temperature and transmits data to the display screen, when the water temperature is lower than the set liquid preparation temperature, such as 30 ℃, the heater 17 is started, the water temperature stops heating after reaching the set temperature, the water level must not exceed the temperature sensor 16 and the heater 17, and the temperature sensor 16 and the heater 17 start to work.
The circulating system works: the pressure pump 20 starts to work, water in the barrel is pressurized from the liquid outlet pipe 19 at the bottom of the barrel and enters the internal circulation pipeline 26 through the four-port conversion head 25 (at the moment, the electromagnetic valve 6 at the position of the internal circulation pipeline 26 is opened, and other electromagnetic valves are closed), the water returns to the barrel from the middle lower part of the liquid distribution barrel 1, the guide pipe 30 is arranged in the barrel, so that the liquid returning to the barrel flows in one direction, and vortex is favorably formed.
The two conductivity sensors 23 monitor in real time and transmit data to the display screen to display the conductivity of the liquid in the barrel.
Adding dialysis concentrated powder into the liquid preparation barrel 1 from the feed inlet 3, pressing the confirmation key of the controller, opening the electromagnetic valve 6 at the liquid inlet pipeline 4 again, closing the electromagnetic valve 6 to close water inlet when the ultrasonic flowmeter 5 detects that the water inlet amount reaches, starting the operation of the temperature sensor 16 and the heater 17 as above, and circulating the operation of the pressure pump 20 as above. The conductivity sensor 23 monitors the conductivity in real time, and when the conductivity reaches the conductivity value after the concentrated powder is completely dissolved, the completion of the solution dissolution preparation is prompted, and whether the next liquid taking and subpackaging are carried out or not is judged.
Taking liquid and subpackaging: entering a liquid taking and subpackaging mode, after a liquid taking key 31 is pressed, a pressure pump 20 pressurizes liquid in a barrel from a liquid outlet pipe 19 at the bottom of the barrel and enters a liquid taking pipeline 27 through a four-port conversion head 25, at the moment, an electromagnetic valve 6 at the position of the liquid taking pipeline 27 is opened, other electromagnetic valves are closed, an ultrasonic flowmeter 5 on the liquid taking pipeline 27 starts to measure, when the liquid taking amount at a single time reaches a set amount, the electromagnetic valve 6 is closed, the pressure pump 20 stops working temporarily, the liquid taking key 31 is pressed again, liquid taking is carried out again, the circulation is carried out, after the liquid taking is finished, a liquid re-dispensing or cleaning dispensing barrel 1 is prompted to enter, the liquid dispensing mode is returned after the liquid re-dispensing, and the cleaning mode is as:
a cleaning mode: cleaning: the system automatically opens the electromagnetic valve 6 at the liquid inlet pipeline 4, the ultrasonic flowmeter 5 starts to calculate the water inlet amount, reverse osmosis water enters the barrel through the liquid inlet pipeline 4, after a certain amount of water enters, the electromagnetic valve 6 is closed, the booster pump 20 starts to work, liquid in the barrel enters the disinfectant circulating pipeline 18 from the liquid outlet pipe 19 to enter the four-port conversion head 25, the electromagnetic valve 6 at the disinfectant circulating pipeline 18 is opened and then is sprayed out through the liquid outlet hole 21 on the annular pipeline 22 to ensure that all parts in the barrel are sprayed, during the period, the electromagnetic valve 6 at the disinfectant circulating pipeline 18 and the electromagnetic valve 6 at the sampling pipeline 27 are alternately opened for a plurality of times to wash out residual liquid in the barrel, so that a disinfection dead cavity is avoided, after the cleaning is finished, the electromagnetic valve 6 at the disinfectant circulating pipeline 18 is closed, the electromagnetic valve 6 at the sampling pipeline 27 is opened to discharge the liquid in the barrel from the sampling pipeline 27, the steps are repeated for, when the conductivity is extremely low and is the same as that of the inlet water, the liquid in the barrel is considered to be drained after the cleaning is finished.
Air drying: after the washing is finished, the air blower 12 is turned on, air is blown into the barrel through the air path pipeline 11, so that residual water on the inner wall of the barrel is taken away by the air, the air in the barrel can be discharged through the one-way exhaust valve 7, and residual moisture in the barrel is dried in the air.
Ultraviolet sterilization: then, an ultraviolet sterilizing lamp on the inner surface of the barrel cover 2 is turned on to sterilize the environment in the barrel, so that the sterile state of the environment in the barrel is ensured.
It should be noted that the description of "first" and "second" in the present invention only distinguishes one operation entity from another operation entity, and does not mean that they have such a sequential relationship;
the above description is only a preferred embodiment of the present invention, and is only for illustrating the technical solutions of the present invention, and not for further limiting the technical solutions of the present invention, and any replacement or change without creative efforts shall be covered within the technical protection of the present invention without departing from the spirit of the present invention, therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
