Detailed Description
The present utility model will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present utility model and not limited to the following examples.
The embodiment of the utility model comprises a preparation and water supplementing DI integrated machine 1, a control system 2, a conveying system 3 and an outlet pipeline 11.
The preparation and supplement DI water all-in-one machine 1 comprises a tap water cavity 4, a water making cavity 5, a water supplementing cavity 6, a filtering device 7, a reverse osmosis membrane device 8, a booster pump 9, a fan 10, a water outlet pipeline 11, a first regulating valve 12 and a second regulating valve 13.
The conveying system 3, the booster pump 9, the fan 10, the first regulating valve 12 and the second regulating valve 13 are all connected with the control system 2.
The water making cavity 5 is divided into an upper cavity 51, a middle cavity 52 and a lower cavity 53 from top to bottom; the filter device 7 is arranged in the water making cavity 5 and is positioned between the upper cavity 51 and the middle cavity 52 to separate the upper cavity 51 and the middle cavity 52; the water making cavity 5 is internally and fixedly provided with a baffle plate 54, and the baffle plate 54 is positioned between the middle cavity 52 and the lower cavity 53 to separate the middle cavity 52 from the lower cavity 53.
The water inlet of the tap water cavity 4 is directly connected with a tap water pipe of a workshop, and tap water is filled in the tap water cavity. The water outlet of the tap water cavity 4 is connected with the upper cavity 51 of the water making cavity 5 through a first regulating valve 12. When receiving the control signal from the control system 2, the first regulating valve 12 is opened, and tap water flows into the upper cavity 51 of the water making cavity 5.
The water outlet of the middle cavity 52 is connected with the water inlet of the reverse osmosis membrane device 8 through the booster pump 9, and the water outlet of the reverse osmosis membrane device 8 is connected with the lower cavity 53. Tap water in the upper chamber 51 flows through the filtering device 7 by gravity into the middle chamber 52, then flows through the reverse osmosis membrane device 8 by the action of the pressurizing pump 9 to prepare DI water which meets the requirements, and flows into the lower chamber 53.
The water outlet of the lower cavity 53 is connected with the water inlet of the water supplementing cavity 6 through the second regulating valve 13. After receiving the control signal sent by the control system 2, the second regulating valve 13 between the water making cavity 5 and the water compensating cavity 6 is opened, and the prepared DI water flows into the water compensating cavity 6. A fan 10 is arranged above the water supplementing cavity 6.
