Description

Technical Field

[0001] This utility model relates to the field of water treatment agent testing, and in particular to a real-world operating condition simulation testing device for corrosion and scale inhibitors. Background Technology

[0002] Corrosion and scale inhibitors can be used in water treatment and have the effect of dissolving scale. Utility model patent CN214334573U discloses a testing device for corrosion and scale inhibitors. A circulating pipe is set between a test tank and a water tank to simulate the scale formation process. After scale formation, the water in the test tank is completely drained to weigh the test tank and the newly formed scale. The corrosion and scale inhibitor is then added for a second circulation, and the above process is repeated for weighing to obtain a more accurate result. However, in this technical solution, the pipe returning from the water tank to the test tank is connected to a flexible hose. The middle of the hose is prone to collapsing, causing water residue to accumulate when it flows through. This residual water affects the weighing result of the load cell. Furthermore, the amount of residual water varies with each circulation and is difficult to determine directly, thus easily leading to errors in the weighing process and affecting the test results. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a real-world operating condition simulation testing device for corrosion and scale inhibitors, which facilitates the drainage of water from the connecting hose, reducing errors and improving the accuracy of test results.

[0004] The technical solution of this utility model is as follows:

[0005] A real-world operating condition simulation testing device for a corrosion and scale inhibitor includes a test chamber, a circulation chamber, a circulation component, and a recovery component. The circulation chamber is located on one side of the test chamber and has an input pipe at its top. A weighing sensor is located at the bottom of the test chamber. The circulation component includes a first water pump, a first suction pipe, a first inlet pipe, an outlet pipe, and a connecting hose. The first water pump is located on the circulation chamber. One end of the first suction pipe is connected to the input end of the first water pump, and the other end extends to the bottom of the test chamber. One end of the first inlet pipe is connected to the output end of the first water pump, and the other end communicates with the interior of the circulation chamber. The outlet pipe is located at the bottom of the circulation chamber. One end of the connecting hose is connected to the outlet pipe, and the other end communicates with the interior of the test chamber.

[0006] The recycling assembly includes a first return pipe, a second return pipe, and a water collection tank. The water collection tank is located between the test chamber and the recycling chamber. The first return pipe is located at the bottom of the test chamber. The second return pipe is connected to the middle of the connecting hose.

[0013] 2. The water in the collection tank can be pumped back to the circulation tank by the second water pump, reducing water loss and facilitating recycling;

[0018] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0019] Example:

[0020] like Figure 1 As shown, a real-world operating condition simulation testing device for a corrosion and scale inhibitor includes a test chamber 10, a circulation chamber 20, a circulation component, and a recovery component. The circulation chamber 20 is located on one side of the test chamber 10, with an input pipe 21 at the top for connecting to a water source or adding the corrosion and scale inhibitor. A weighing sensor 30 is located at the bottom of the test chamber 10 for weighing the total weight of the test chamber 10 and the scale, and displaying the result on an existing display device. The circulation component includes a first water pump 41, a first suction pipe 42, a first inlet pipe 43, an outlet pipe 44, and a connecting hose 45. The first water pump 41 is located on the circulation chamber 20, and one end of the first suction pipe 42 is connected to the input end of the first water pump 41, while the other end extends to the bottom of the test chamber 10. The first inlet pipe 43 is connected at one end to the output end of the first water pump 41, and at the other end to the interior of the circulation tank 20; the outlet pipe 44 is located at the bottom of the circulation tank 20, and one end of the connecting hose 45 is connected to the outlet pipe 44, and the other end is connected to the interior of the test chamber 10; the recovery assembly includes a first return pipe 51, a second return pipe 52 and a water collection tank 53, the water collection tank 53 is located between the test chamber 10 and the recovery tank, the first return pipe 51 is located at the bottom of the test chamber 10, the second return pipe 52 is connected to the middle of the connecting hose 45, and the ends of the first return pipe 51 and the second return pipe 52 are both located at the top of the water collection tank 53; valves are respectively provided on the outlet pipe 44, the first return pipe 51 and the second return pipe 52.

[0021] The working principle of the above technical solution is as follows:

[0022] Before use, the weight of the test chamber 10 is measured using the weighing sensor 30. During use, a specified amount of water is injected into the circulation tank 20 through the input pipe 21, and the valve on the outlet pipe 44 is opened, allowing water to flow into the test chamber 10. The first water pump 41 is then turned on, and the water in the test chamber 10 is pumped back into the circulation tank 20 through the first suction pipe 42, forming a circulation to simulate the process of limescale formation. After limescale has formed, the valve on the outlet pipe 44 is closed, and the first water pump 41 is used to pump out all the water in the test chamber 10. Then, the valves on the first return pipe 51 and the second return pipe 52 are opened to remove the remaining water in the test chamber 10 and the connecting hose 4, respectively. The residual water in chamber 5 is drained into the collection tank 53 for recycling. Draining the residual water helps the weighing sensor 30 to weigh the total weight of the test chamber 10 and the scale, reducing errors. After drainage, the valves of the first return pipe 51 and the second return pipe 52 are closed, and the outlet pipe 44 and the first water pump 41 are opened again. Corrosion and scale inhibitors are added from the input pipe 21 and the circulation tank 20 for a second circulation. After circulation, the above operation of draining the water in the test chamber 10 and the water in the connecting hose 45 is repeated. The total weight of the scale and the test chamber 10 is weighed using the weight sensor, which helps to calculate the weight difference before and after adding the corrosion and scale inhibitors and obtain the test results.

[0023] In another embodiment, such as Figure 1 As shown, the bottom of the test chamber 10 is inclined from high to low along the direction of gradually approaching the first return pipe 51; a support platform 60 with its top surface matching the bottom surface of the test chamber 10 is provided between the bottom of the test chamber 10 and the weighing sensor 30.

[0024] It facilitates the outflow of residual water at the bottom of the test chamber 10 through the first return pipe 51; the support platform 60 provides stable support based on the bottom shape of the test chamber 10.

[0025] In another embodiment, such as Figure 1 As shown, the bottom of the circulation box 20 is provided with a support 22, and the top of the support 22 is higher than the higher side of the bottom of the test box 10.

[0026] This helps ensure that the water in test chamber 10 flows back into test chamber 10 stably.

[0027] In another embodiment, such as Figure 1 As shown, the circulation assembly also includes a second water pump 46, a second water suction pipe 47, and a second water inlet pipe 48. One end of the second water suction pipe 47 is connected to the input end of the second water pump 46, and the other end extends to the bottom of the inner side of the water collection tank 53. One end of the second water inlet pipe 48 is connected to the output end of the second water pump 46, and the other end is connected to the top of the circulation tank 20.

[0028] Water in the collection tank 53 can be pumped back to the circulation tank 20 by the second water pump 46, reducing water loss and facilitating recycling.

[0029] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
