Description

Technical Field

[0001] The utility model relates to a uniform and stable automatic water efficiency marking system, belonging to the technical field of marking systems. Background Art

[0002] With the development of society and the improvement of people's living standards, people's health awareness has continued to improve and strengthen, and their requirements for drinking water quality have also increased. In some areas, the tap water quality cannot fully meet the residents' demand for drinking water quality and safety. Water purifiers have become the choice of many families.

[0003] At present, water efficiency tests on water purifiers are carried out in accordance with the national standard GB 34914, but there are problems such as long manual water distribution time, low efficiency, high intensity, and impact on test continuity. There are also relevant reports on water purifier testing. For example, the patent application with application number 202010520050.8 discloses an automatic testing system and method for the water production efficiency of a water purifier. By setting a metering device, the water production efficiency of the water purifier is automatically tested. However, no improvement has been made to the configuration of the water source addition. In actual testing work, the inventors found that if the method of mixing and using at the same time is adopted, the stability is poor and the accuracy is low. To this end, the inventors designed a uniform and stable automatic water efficiency addition system to ensure the high uniformity of the standard solution and ensure the accuracy and stability of the detection. Utility Model Content

[0004] The utility model provides a uniform and stable automatic water efficiency spike system. Different solutions are first prepared in corresponding solution barrels, and then measured by metering tanks and enter the spike barrel. After the standard liquids are evenly mixed, they enter the test. At the same time, different water quality monitoring sensors are set up, which can more accurately control the water quality to meet the standard requirements, thereby improving the accuracy and stability of the detection.

[0005] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] The number of solution barrels is more than four, each of which is provided with a feeding port and a stirring device;

[0008] One end of the first delivery pipe is connected to the pure water source, and the other end is branched into four or more first delivery branches A and two or more first delivery branches B. A solenoid valve is provided on the first delivery pipe before the branch;

[0013] One end of the water outlet pipe is connected to the purified water outlet of the water purifier to be tested, and the other end leads to the purified water collection bucket; the second flow sensor is arranged on the water outlet pipe.

[0014] The pure water source can be a container for storing pure water or a pure water preparation system. One end of the first delivery pipe is connected to the water outlet of the pure water preparation system. Opening the solenoid valve on the first delivery pipe before the branch allows the pure water to enter the solution tank or the spiked tank under the action of water pressure.

[0015] The system also includes a wastewater pipe, one end of which is connected to the wastewater outlet of the water purifier under test and the other end of which is connected to a wastewater treatment device for reuse after treatment. Alternatively, the wastewater can be collected and then directed to the wastewater treatment device for treatment. Existing equipment can be used for the wastewater treatment device, and this application does not specifically improve this equipment, so it will not be described in detail.

[0016] The sequential arrangement mentioned in this application refers to sequential arrangement from upstream to downstream, which is also the direction of liquid flow.

[0017] The above-mentioned four or more solution barrels are provided for preparing different solutions. The two or more spiked barrels are provided for backup and continuous measurement.

[0018] According to the spatial structure of different testing rooms, metering pumps, solenoid valves, etc. can be installed on each pipeline as needed.

[0019] To further improve the uniformity of the standard solution, each spiking barrel is equipped with a circulation system consisting of a circulation tube, a temperature controller, and a circulation pump. One end of the circulation tube is connected to the top of the corresponding spiking barrel, and the other end is connected to the bottom of the barrel. The temperature controller and circulation pump are installed on the circulation tube. This temperature controller ensures that the standard solution meets the standard requirements.

[0020] In order to facilitate the collection of clean water, there are more than two clean water collection barrels. One end of the outlet pipe is connected to the clean water outlet of the water purifier to be tested, and the other end is branched into two clean water branches. The number of clean water branches is equal to the number of clean water collection barrels and corresponds one to one.

[0021] To facilitate monitoring of water volume and quality, the outlet pipe before the branch is equipped with a solenoid valve, a second conductivity sensor, and a second flow sensor. When the conductivity sensors at the inlet and outlet of the water purifier under test (the first conductivity sensor at the inlet and the second conductivity sensor at the outlet) detect a removal rate below 85%, the test is terminated and the water supply is stopped.

[0022] In order to facilitate the reuse of clean water, the above-mentioned uniform and stable automatic water efficiency tagging system also includes a reflux pipe, one end of which is connected to the first delivery pipe before the branch, and the other end is branched into two or more reflux branches. The number of reflux branches is equal to the number of clean water collection barrels and corresponds one to one. Each reflux branch is connected to the bottom of the corresponding clean water collection barrel. Each reflux branch is respectively provided with a solenoid valve, and the reflux pipe before the branch is provided with a solenoid valve and a reflux pump; the connection point between the reflux pipe and the first delivery pipe is located upstream of the solenoid valve on the first delivery pipe before the branch.

[0023] In order to facilitate installation and control, the solenoid valve on the return pipe before the branch and the solenoid valve on the first delivery pipe before the branch are replaced by a three-way valve.

[0024] The delivery pump and reflux pump mentioned in this application are preferably metering pumps, and existing commercial products can be directly purchased.

[0025] To improve the accuracy of water volume monitoring, a weighing plate is installed at the bottom of each purified water collection barrel. This system combines a flow sensor with a weighing plate to measure the water output. This application does not specifically improve the structure and principle of the weighing plate, but directly refers to existing mature technologies and will not be elaborated on here.

[0026] To simultaneously measure wastewater, the uniform and stable automatic water efficiency spike system also includes a wastewater collection bucket and a wastewater pipe. One end of the wastewater pipe is connected to the wastewater outlet of the water purifier under test, and the other end is connected to the wastewater collection bucket. A weighing plate is installed at the bottom of the wastewater collection bucket to measure wastewater. The wastewater in the wastewater collection bucket is finally piped to a wastewater treatment device for treatment.

[0027] The first branch pipe A extends from the top of the solution barrel into the solution barrel. Specifically, the first branch pipe A extends from the top of the corresponding solution barrel into the corresponding solution barrel. The first branch pipe B extends from the top of the spiked barrel into the spiked barrel. Specifically, the first branch pipe B extends from the top of the corresponding spiked barrel into the corresponding spiked barrel.

[0028] When the amount of liquid in the metering tank reaches the required level, the corresponding solenoid valve is closed at the same time.

[0029] To meet general testing needs, four solution tanks and two spike tanks are used. These two spike tanks are connected in parallel, with one for testing and the other on standby. The corresponding solutions in the solution tanks can be prepared in advance, ensuring each solution is prepared independently and does not affect the other.

[0030] The four solution barrels are: 1# solution barrel, 2# solution barrel, 3# solution barrel and 4# solution barrel.

[0031] Solution preparation: Add 7530g of calcium chloride dihydrate and 2500mL of hydrochloric acid (1250ml of concentrated hydrochloric acid (37% by mass) and 1250ml of water) to solution bucket #1; add 6320g of magnesium sulfate heptahydrate to solution bucket #2; add 7960g of sodium bicarbonate to solution bucket #3; and add 240ml of 8% sodium hypochlorite and 2370g of sodium chloride to solution bucket #4. Open the solenoid valve on the first delivery pipe before the branch, close the solenoid valve on the first delivery branch pipe B, and then activate the solenoid valves on each first delivery branch pipe A in sequence. Add 200L of pure water to each solution bucket and stir to dissolve. This recipe consistently produces water that meets the requirements of GB34914.

[0032] Automatic water distribution: Set the addition volume for each solution barrel to 20L. Close the solenoid valves on each first delivery branch pipe A, open the solenoid valves on the first delivery pipe before the branch and the solenoid valves on the first delivery branch pipe B, and add 3000L of pure water to the spiked barrel. Then, close the solenoid valve on the first delivery pipe before the branch, start the solenoid valves and metering pumps on each first delivery branch pipe A in sequence, and add solution barrels 1-4 in order. Each solution barrel is transferred to the metering tank via the metering pump. When the liquid level probe in the metering tank reaches 20L, close the solenoid valve and metering pump on the corresponding solution delivery pipe, and open the solenoid valve on the second delivery pipe corresponding to one of the spiked barrels to allow the liquid in the metering tank to flow into the spiked barrel. Then start the solenoid valve on the first delivery pipe before the branch to fill the metering tank with pure water to rinse the metering tank. Repeat this process to add solutions 2#, 3#, and 4#. Turn on the stirring device and circulation pump on the spiked barrel, as well as the temperature controller, to stir the spiked solution and maintain a constant temperature (25 ± 1°C). Follow the previous steps to complete the configuration of each spiked barrel.

[0033] The solution prepared in each spiked barrel meets the requirements in the following table:

[0034] Water quality parameters Target value Total hardness 230~270mg / L Total alkalinity 130~150mg / L pH 7.0～7.5 Conductivity 900~1100us / cm Turbidity ≤1NTU water temperature 24～26℃

[0035] Spiking: The prepared solution in the spiked solution bucket is delivered to the water purifier to be tested through the delivery pump. The first conductivity sensor, turbidity sensor, pH sensor, temperature sensor, pressure sensor and first flow sensor will collect information such as conductivity, turbidity, pH, temperature, pressure, flow, and water flow of the spiked solution.

[0036] Sampling is performed when the water purification output of the water purifier under test reaches 0%, 25%, 50%, 75%, and 100% of the rated total water purification output, respectively. When the nominal rated total water purification output is reached, the total inlet water volume and the total concentrated water volume are recorded. Of course, not every water purifier under test can reach the rated total water purification output. During the process, if the removal rate detected by the conductivity sensors at the inlet and outlet of the water purifier under test (the first conductivity sensor at the inlet and the second conductivity sensor at the outlet) falls below 85%, the test is terminated and the water supply is stopped.

[0037] The technologies not mentioned in this utility model are all referred to the existing technology.

[0038] The utility model is a uniform and stable automatic water efficiency spike system. After each solution is evenly mixed in the corresponding solution barrel, it is accurately weighed in a metering tank before being added to the spike barrel for mixing. This ensures the high uniformity of the standard solution and improves the accuracy and stability of the test. Multiple solution barrels are used to prepare different solutions, which are weighed in a metering tank before entering the spike barrel. This reduces the mutual influence between different substances and improves the accuracy of solution configuration. After the solution in the spike barrel is prepared, it immediately enters the test. At the same time, different water quality monitoring sensors are set up to more accurately control the water quality to meet the standard requirements. Furthermore, the spike barrel ensures the uniformity of the solution through a combination of mechanical stirring and a circulating pump. At the same time, the temperature of the standard solution is precisely controlled. It can be combined with existing control systems and control methods to achieve fully automated water efficiency testing and improve efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Example 5

[0059] Based on Example 4, the following improvements were made: Metering pumps were also preferably used for both the delivery pump and the return pump. A weighing plate was installed at the bottom of each purified water collection bucket. This allowed for a combination of multiple methods to achieve metering, improving accuracy.

[0060] Example 6

[0061] Based on Example 5, the following improvements were made: To simultaneously measure wastewater, the uniform and stable automatic water efficiency spike system further includes a wastewater collection bucket and a wastewater pipe. One end of the wastewater pipe is connected to the wastewater outlet of the water purifier to be tested, and the other end is connected to the wastewater collection bucket. A weighing plate is provided at the bottom of the wastewater collection bucket to measure wastewater. The wastewater in the wastewater collection bucket is finally piped to a wastewater treatment device for treatment.

[0062] The first delivery branch pipe A extends from the top of the solution tank into the solution tank. The first delivery branch pipe B extends from the top of the spiked tank into the spiked tank. When the liquid level in the metering tank reaches the required level, the corresponding solenoid valve and metering pump are closed simultaneously.

[0063] In this example, there are four solution tanks and two spike tanks. These two spike tanks are connected in parallel, with one for testing and the other on standby. The corresponding solutions in the solution tanks can be prepared in advance, so each solution is prepared separately and does not affect the other.

[0064] The four solution barrels are: 1# solution barrel, 2# solution barrel, 3# solution barrel and 4# solution barrel.

[0065] Solution preparation: Add 7530g of calcium chloride dihydrate and 2500mL of hydrochloric acid (37% mass concentration) to solution bucket #1; add 6320g of magnesium sulfate heptahydrate to solution bucket #2; add 7960g of sodium bicarbonate to solution bucket #3; and add 240ml of 8% sodium hypochlorite and 2370g of sodium chloride to solution bucket #4. Open the solenoid valve on the first delivery pipe before the branch, close the solenoid valve on the first delivery branch B, and then start the solenoid valves and metering pumps on each first delivery branch A in sequence. Add 200L of pure water to each solution bucket and stir to dissolve. This recipe consistently produces water that meets the requirements of GB34914.

[0066] Automatic water distribution: Set the addition volume for each solution barrel to 20L. Close the solenoid valves on each first delivery branch pipe A, open the solenoid valves on the first delivery pipe before the branch and the solenoid valves on the first delivery branch pipe B, and add 3000L of pure water to the spiked barrel. Then, close the solenoid valve on the first delivery pipe before the branch, start the solenoid valves and metering pumps on each first delivery branch pipe A in sequence, and add solution barrels 1-4 in order. Each solution barrel is transferred to the metering tank via the metering pump. When the liquid level probe in the metering tank reaches 20L, close the solenoid valve and metering pump on the corresponding solution delivery pipe, and open the solenoid valve on the second delivery pipe corresponding to one of the spiked barrels to allow the liquid in the metering tank to flow into the spiked barrel. Then start the solenoid valve on the first delivery pipe before the branch to fill the metering tank with pure water to rinse the metering tank. Repeat this process to add solutions 2#, 3#, and 4#. Turn on the stirring device and circulation pump on the spiked barrel, as well as the temperature controller, to stir the spiked solution and maintain a constant temperature (25 ± 1°C). Follow the previous steps to complete the configuration of each spiked barrel.

[0067] The solution prepared in each spiked barrel meets the requirements in the following table:

[0068] Water quality parameters Target value Total hardness 230~270mg / L Total alkalinity 130~150mg / L pH 7.0～7.5 Conductivity 900~1100us / cm Turbidity ≤1NTU water temperature 24～26℃

[0069] Spiking: The prepared solution in the spiked solution bucket is delivered to the water purifier to be tested through the delivery pump. The first conductivity sensor, turbidity sensor, pH sensor, temperature sensor, pressure sensor and first flow sensor will collect information such as conductivity, turbidity, pH, temperature, pressure, flow, and water flow of the spiked solution.

[0070] Sampling is performed when the water purification output of the water purifier under test reaches 0%, 25%, 50%, 75%, and 100% of the rated total water purification output, respectively. When the nominal rated total water purification output is reached, the total inlet water volume and the total concentrated water volume are recorded. Of course, not every water purifier under test can reach the rated total water purification output. During the process, if the removal rate detected by the conductivity sensors at the inlet and outlet of the water purifier under test (the first conductivity sensor at the inlet and the second conductivity sensor at the outlet) falls below 85%, the test is terminated and the water supply is stopped.

[0071] Practical verification has shown that this uniform and stable automatic water efficiency spike system can more accurately control water quality and temperature to meet standard requirements compared to methods such as simultaneous dispensing, with significantly improved accuracy and stability. Using this uniform and stable automatic water efficiency spike system, water quality parameter errors are all within 4%. For example, the conductivity error is between 2% and 4%. Seven water dispensing tests were conducted within this error range, demonstrating good stability. However, using a direct metering pump for simultaneous dispensing can lead to pipe blockages caused by scaling and errors in the metering pump's own pumping of the solution, resulting in conductivity errors of 18% to 24%. Combining this with existing control systems and methods enables fully automated water efficiency testing, improving efficiency.
