[0038] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0039] like Figure 1 and Figure 2As shown, this embodiment provides an automatic chemical concentration adjustment system for supplying RO chemical solutions of a predetermined concentration to a disinfection device. The automatic chemical concentration adjustment system includes a tank 1, a piping assembly 4, and a concentration sensor 2, which work together to achieve automatic adjustment of the RO chemical concentration. The tank 1 has an RO pure water inlet 11, a chemical inlet 12, an RO chemical mixture outlet 13, and a recovery port. The RO pure water inlet 11 is used to replenish RO pure water into the tank 1, and the chemical inlet 12 is used to replenish chemical solutions into the tank 1. The RO (Reverse Osmosis) pure water and the chemical solutions mix within the tank 1 to form the RO chemical solution, while the RO chemical mixture outlet 13 is used to discharge the RO chemical solution from the tank 1. The piping assembly 4 includes an outlet pipe 45, a return pipe 41, and a drain pipe 42. The RO chemical solution mixing outlet 13 is connected to the inlet of the disinfection device via the outlet pipe 45, meaning that the RO chemical solution mixed in the tank 1 can be supplied to the disinfection device through the outlet pipe 45. The recovery port is connected to the drain port of the disinfection device via the return pipe 41. A filter 3 is installed on the return pipe 41, meaning that the RO chemical solution used by the disinfection device can be returned to the tank 1 through the return pipe 41 after being filtered by the filter 3, thus realizing the recycling of the RO chemical solution. The concentration sensor 2 has a first sampling point 21, a second sampling point 22, and a third sampling point 23. The first sampling point 21 is located inside the tank 1 to detect the concentration of the RO chemical solution mixed in the tank 1, ensuring that the RO chemical solution is discharged from the tank 1 to the disinfection device only when the concentration meets the predetermined concentration through the RO chemical solution mixing outlet 13. The second sampling point 22 is located on the outlet pipe 45, allowing for concentration detection of the RO solution flowing a certain distance within the outlet pipe 45. The RO solution is further mixed and homogenized during flow. A sampling point for the concentration sensor 2 is also located here to ensure the accuracy of concentration detection of the RO solution flowing towards the disinfection device. The third sampling point 23 is located on the return pipe 41, between the filter 3 and the drain pipe 42, to detect the concentration of the RO solution after filtration by the filter 3, ensuring that the concentration of the recovered RO solution meets the standard before recycling. The automatic solution concentration mixing system provided in this embodiment can achieve continuous automatic mixing of RO solution without the need for a large tank 1 or manual mixing, saving space and manpower.
[0040] Optionally, the automatic drug concentration mixing system also includes a water pump 8, which is installed on the drain pipe 42 and located upstream of the second sampling point 22. The water pump 8 is used to draw RO drug solution from the tank 1 so that it can quickly flow out of the tank 1 through the RO drug solution mixing outlet 13. While accelerating the flow of RO drug solution, the water pump 8 can also further promote the mixing of RO drug solution, thereby promoting uniform mixing of RO drug solution and improving the concentration detection accuracy at the second sampling point 22.
[0041] Furthermore, the tank 1 has an overflow port 14, and the overflow port 14 is equipped with an overflow pipe 46, which is used to discharge liquid in the tank 1 that exceeds the predetermined liquid level. The overflow port 14 is located at the warning water level line of the tank 1. When the water level of the RO chemical solution in the tank 1 rises to the warning water level line, the RO chemical solution will flow out from the overflow port 14 to ensure the safe use of the tank 1.
[0042] Optionally, a first liquid level sensor 5 is installed inside the tank 1, and an overflow valve is installed on the overflow pipe 46. The overflow valve is signal-connected to the first liquid level sensor 5. The first liquid level sensor 5 is used to detect whether the water level of the RO chemical solution in the tank 1 has reached the first water level line, which is also the warning water level line. When the water level of the RO chemical solution has reached the first water level line, the overflow valve is controlled to open to ensure that the RO pure water exceeding the first water level line flows out of the tank 1. When the RO chemical solution drops below the first water level line, the overflow valve can be closed to ensure the isolation of the internal and external environments of the tank 1.
[0043] Optionally, the pipe assembly 4 also includes a first replenishment pipe 43. The RO pure water inlet 11 is connected to the RO pure water storage tank through the first replenishment pipe 43. A first replenishment valve is installed on the first replenishment pipe 43. The first replenishment valve is used to open when it is necessary to replenish RO pure water into the tank 1, and to close when it is not necessary to replenish RO pure water into the tank 1. The pipe assembly 4 also includes a second replenishment pipe 44. The chemical inlet 12 is connected to the chemical storage tank through the second replenishment pipe 44. A second replenishment valve is installed on the second replenishment pipe 44. The second replenishment valve is used to open when it is necessary to replenish chemical solution into the tank 1, and to close when it is not necessary to replenish chemical solution into the tank 1. To further improve the automation of chemical solution concentration preparation, a second liquid level sensor 7 is also installed in the tank 1. The second liquid level sensor 7 is located vertically below the first liquid level sensor 5. Both the first replenishment valve and the second replenishment valve are signal-connected to the second liquid level sensor 7. The second liquid level sensor 7 is used to detect whether the water level of the RO chemical solution in the tank 1 is at the low water level line, which is the second water level line. The second water level line is located below the first water level line. When the water level of the RO chemical solution has reached the second water level line, both the first replenishment valve and the second replenishment valve need to be opened to ensure that RO pure water and chemical solution are replenished into the tank 1 in a timely manner so as to adjust the RO chemical solution in a timely manner.
[0044] Optionally, a third liquid level sensor 6 is also installed inside the tank 1. The third liquid level sensor 6 is located vertically between the first liquid level sensor 5 and the second liquid level sensor 7. A liquid outlet valve is installed on the liquid outlet pipe 45, and the liquid outlet valve is connected to the third liquid level sensor 6 for signal transmission. The third liquid level sensor 6 is used to detect whether the water level of the RO chemical solution in the tank 1 has reached the third water level line, which is the middle water level line and is located between the warning water level line and the low water level line. The liquid outlet valve can only be opened when the water level of the RO chemical solution has reached the third water level line to supply RO chemical solution to the disinfection device, so as to ensure that the RO pure water and the chemical solution have sufficient time and space to mix evenly in the tank 1 each time they are prepared.
[0045] Furthermore, the tank 1 also has a drain port 15, with a drain pipe 47 installed on the drain port 15. A drain valve is installed on the drain pipe 47, which is used to discharge the liquid inside the tank 1. The drain port 15 is used to promptly discharge any remaining medicine inside the tank 1 after use, in order to empty the tank 1.
[0046] In this embodiment, one end of the overflow pipe 46 is connected to the overflow port 14, and the other end of the overflow pipe 46 is connected to the drain pipe 42. One end of the drain pipe 42 is connected to the return pipe 41, and the other end of the drain pipe 42 is connected to the sewage pipe 47. That is, the RO chemical solution that fails to meet the standards after being filtered by the filter 3, as well as the RO chemical solution discharged when emptying the tank 1, ultimately flow to the outlet of the sewage pipe 47 to flow into the sewage treatment tank. In other embodiments, the other end of the drain pipe 42 and the end of the sewage pipe 47 not connected to the sewage port 15 can also be connected to the sewage treatment tank respectively.
[0047] In this embodiment, the chemical inlet 12 and the recovery port are the same opening. One end of the second replenishment pipe 44 is connected to the chemical storage tank, and the other end of the second replenishment pipe 44 is connected to the first port of the return pipe 41. The drain pipe 42 is connected to the second port of the return pipe 41, with the first port located downstream of the second port. That is, the RO chemical solution that meets the standards after filtration by the filter 3, as well as the chemical solution replenished to the tank 1 through the chemical storage tank, can all enter the tank 1 through the chemical inlet 12, which is also the recovery port. This arrangement can reduce the number of openings on the tank 1. In other embodiments, the chemical inlet 12 and the recovery port can also be set separately, and the other end of the second replenishment pipe 44 can be directly connected to the chemical inlet 12, the first port of the return pipe 41 can be connected to the recovery port, and the second port located upstream of the first port can still be connected to the drain pipe 42. In practice, a return valve is installed on the return pipe 41 and a drain valve is installed on the drain pipe 42. When the third sampling point 23 detects that the recovered RO chemical solution is qualified, the return valve is opened and the recovered RO chemical solution enters the tank 1 through the return valve. When the third sampling point 23 detects that the recovered RO chemical solution is unqualified, the drain valve is opened and the recovered RO chemical solution is discharged to the sewage treatment pond through the drain valve.
[0048] Optionally, the automatic drug concentration mixing system also includes a base 9, with the tank 1 mounted on the base 9. In practice, the drain outlet 15 is located at the bottom of the tank 1, and the drain pipe 47 can pass through the base 9 from below and connect to the drain outlet 15.
[0049] Combination such as Figure 3 The control flow of the automatic drug concentration mixing system provided in this embodiment is as follows: At the start of mixing, the first replenishment valve and the second replenishment valve are opened to replenish RO pure water and drug solution into the tank 1, respectively. The concentration sensor 2 uses the first sampling point 21 to detect the concentration of the RO drug solution mixed in the tank 1. When the concentration of the RO drug solution meets the predetermined concentration and the water level reaches the third water level line, the outlet valve is opened to provide RO drug solution to the inlet of the disinfection device. The disinfection device uses RO drug solution to clean the bottle caps, and the drug solution used to clean the bottle caps can also be recovered through the outlet of the disinfection device. The recovered RO drug solution passes through the filter 3 via the return pipe 41 and flows through the third sampling point 23 located on the return pipe 41 after filtration. Concentration sensor 2 detects the concentration of the RO solution at the third sampling point 23. When the concentration of the recovered RO solution meets the predetermined concentration, it can enter the tank 1 through the recovery inlet. When the concentration of the recovered RO solution does not meet the predetermined concentration, it flows to the drain pipe 42 and is discharged through the sewage pipe 47 connected to the drain pipe 42. This automatic RO solution concentration mixing system can realize continuous automatic mixing of RO solution without the need for a large tank 1 or manual mixing, thus saving space and manpower.
[0050] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
