Description

Technical Field

[0001] This utility model relates to the technical field of purified water, and in particular to a purified water storage tank that is easy to sample. Background Technology

[0002] A purified water storage tank is a large container specifically designed for storing and distributing "purified water." It is not an ordinary water tank, but a core component of process water systems in high-end industries such as pharmaceuticals, bioengineering, electronics, and cosmetics. Here, "purified water" specifically refers to high-purity water that has undergone a series of precise treatments (such as reverse osmosis, electro-deionization, and distillation) to remove impurities such as electrolytes, organic matter, microorganisms, and endotoxins. Its water quality indicators must strictly comply with relevant standards (such as the Chinese Pharmacopoeia).

[0003] Referring to patent CN223162304U, a purified water storage tank for easy sampling is disclosed, including a storage tank body, a mounting base, and a faucet. The mounting base is located on the side of the storage tank body, and the faucet is mounted on the side of the mounting base. A fixing rod is located on the outside of the storage tank body, with a turntable base connected to the top of the fixing rod. A connecting rod is connected to the outside of the turntable base, and a ring is connected to the other side of the connecting rod. This purified water storage tank for easy sampling, by installing a fixing rod, turntable, ring, metal sheet, and magnetic attractant on the outside of the storage tank body, facilitates sampling from multiple test tubes. Opening the faucet allows purified water to flow into the sampling tube. Rotating the turntable base causes the magnetic attractant at the bottom of the next sampling tube to attract the metal sheet, thus fixing the position and facilitating purified water sampling. Therefore, it is convenient to perform multiple purified water sampling operations, and the operation is relatively simple.

[0004] When sampling purified water, the sampling port may not be at the optimal condition point of the circulation pipeline, which may result in a false negative test result. This may prevent the detection of actual microbial contamination risks and make it easy for microorganisms and particles in the environment to enter the water sample during operation, leading to false negative test results as well. This makes it impossible to determine whether the contamination comes from the system or from the sampling process itself. Utility Model Content

[0005] Given that existing purified water storage tanks may cause false negatives when sampling purified water because the sampling port is not at the optimal condition point of the circulation pipeline, and microorganisms and particles in the environment can easily enter the water sample during operation, making it impossible to determine whether the contamination comes from the system or the problem itself during the sampling process, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a purified water storage tank that facilitates sampling, including a purification tank, a first control valve fixedly installed at the middle position of the right end of the purification tank, a filter fixedly installed at the right end of the purification tank, and a water intake component provided on the side wall of the purification tank. A sampling tank is fixedly installed at the lower end of the right end of the purification tank, and a diversion component is provided in the body of the sampling tank, and a protective component is provided on the outside of the sampling tank.

[0007] In this example, a first connecting pipe is fixedly installed on the top of the filter, and the left end of the first connecting pipe is connected to the right end of the first control valve. A filter element is fixedly installed inside the filter.

[0008] In this example, the water intake assembly includes a delivery pipe. The delivery pipe is fixedly installed on the side wall of the purification tank. A second connecting pipe is fixedly installed at the middle position of the top of the delivery pipe body. The right end of the second connecting pipe body is fixedly connected to the lower end of the left end of the filter. A third connecting pipe is fixedly installed in an array at the bottom of the delivery pipe body. The body of the third connecting pipe is connected to the left end of the top of the sampling tank.

[0009] In this example, the diversion component includes a partition plate. The front and rear ends of the inner cavity at the right end of the sampling tank are fixedly installed with partition plates. The left end of the sampling tank is arranged in an array with through holes. The bottom of the sampling tank is fixedly installed with a second control valve in an array.

[0010] In this example, the inner cavity at the left end of the sampling tank is set in an inclined state, and a filter plate is fixedly installed in the inner cavity at the left end of the sampling tank.

[0011] In this example, the protective component includes a sliding groove. The front and rear ends of the sampling slot box are fixedly installed with sliding grooves, and a transparent cover plate is slidably connected inside the sliding groove. The length of the transparent cover plate is greater than the exposed length of the sampling slot box.

[0012] In this example, the sliding groove has an array of screws inside, and both the front and rear ends of the left end of the transparent cover are connected to screws by threads, and the shank of the screw is connected to the positioning hole by threads.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model allows purified water to enter the filter through the first connecting pipe by turning the first control valve. Impurities are filtered out by the filter element inside the filter. Then, the filtered purified water is discharged into the delivery pipe through the second connecting pipe. At the same time, the purified water is discharged into the sampling tank through the third connecting pipe installed in an array at the bottom of the delivery pipe. The combination of filtration and multiple pipelines greatly reduces the risk of introducing environmental microorganisms or particulate contamination during the sampling process, and makes the sampling process more convenient and faster. This ensures that the water sample that best represents the true state of the system is obtained, thereby guaranteeing the accuracy and reliability of the test results.

[0014] 2. This utility model allows for secondary filtration of purified water through a filter plate inside the sampling tank. Because partition plates are fixedly installed at both ends of the right-side inner cavity of the sampling tank, the inner cavity is divided into three independent areas. Through-holes are arrayed on the left side of the sampling tank, allowing purified water to be discharged into individual tanks. Multiple sampling chambers ensure that all test samples come from the same water source at the same time, achieving data synchronization and comparability, thus ensuring the comprehensive accuracy of water quality test results.

[0015] 3. This utility model uses a transparent cover plate that slides within the sliding trough. The length of the transparent cover plate is greater than the exposed area at the right end of the sampling tank, thus protecting the purified water sampled from the right end of the sampling tank. Because the sliding trough has arrayed positioning holes, screws at both ends of the transparent cover plate can be screwed in, and the screw shafts are threaded into the positioning holes, fixing the transparent cover plate to the sliding trough and shielding the purified water within the sampling tank. The cooperation between the transparent cover plate and the sampling tank reduces the contact area and time between the water sample and air, ensuring that the extracted water sample accurately reflects the original quality of the purified water in the storage tank, providing effective data for water quality assessment.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a purified water storage tank that is easy to sample. This purified water storage tank includes a purification tank 1, a first control valve 2 fixedly installed at the middle position of the right end of the purification tank 1, a filter 3 fixedly installed at the right end of the purification tank 1, a water intake component provided on the side wall of the purification tank 1, a sampling tank 9 fixedly installed at the lower end of the right end of the purification tank 1, a diversion component provided in the body of the sampling tank 9, and a protective component provided on the outside of the sampling tank 9.

[0020] In this example, a first connecting pipe 4 is fixedly installed on the top of the filter 3, and the left end of the first connecting pipe 4 is connected to the right end of the first control valve 2, which reduces the number of pipe interfaces, reduces the risk of leakage, and makes the filtration path smoother, reduces water flow resistance, and ensures the efficiency of purified water delivery. A filter element 6 is fixedly installed inside the filter 3, which can continuously intercept impurities and microorganisms in the water, ensuring that the quality of the output water is uniform and meets the standards.

[0021] In this example, the water intake assembly includes a delivery pipe 7. The delivery pipe 7 is fixedly installed on the side wall of the purification tank 1, and a second connecting pipe 5 is fixedly installed at the middle position of the top of the delivery pipe 7. The right end of the second connecting pipe 5 is fixedly connected to the lower end of the left end of the filter 3. The bottom of the delivery pipe 7 is fixedly installed with a third connecting pipe 8 in an array, and the body of the third connecting pipe 8 is connected to the left end of the top of the sampling tank 9. This reduces the risk of external air and impurities seeping in, while avoiding stagnant water residue in the pipeline, ensuring that the filtered purified water remains clean during the transportation process.

[0022] In this example, the diversion component includes a partition plate 10. The partition plates 10 are fixedly installed at both the front and rear ends of the inner cavity of the right end of the sampling tank 9. The left end of the sampling tank 9 is provided with through holes 16 in an array state, so that the water samples flowing in from different through holes do not interfere with each other, completely eliminating cross-contamination of samples and ensuring the independence and accuracy of each set of test data. The bottom of the sampling tank 9 is fixedly installed with a second control valve 17 in an array.

[0023] In this example, the inner cavity at the left end of the sampling tank 9 is set in an inclined state. The inclined surface can guide the water flow to flow gently along the slope, avoiding the water flow from hitting the inner wall of the tank vertically and causing water sample splashing. In addition, a filter plate 11 is fixedly installed in the inner cavity at the left end of the sampling tank 9, which can intercept tiny impurities that may be mixed in during pipeline transportation.

[0024] In this example, the protective component includes a sliding groove 12. The front and rear ends of the sampling tank 9 are fixedly installed with sliding grooves 12, and a transparent cover plate 13 is slidably connected inside the sliding groove 12, so that the liquid level of the water sample in the sampling tank can be directly observed. Furthermore, the length of the transparent cover plate 13 is greater than the exposed length of the sampling tank 9, which can prevent the water sample odor from escaping and take into account both water quality cleanliness and a clean operating environment.

[0025] In this example, the sliding groove 12 has an array of screws 15 inside. The front and rear ends of the left end of the transparent cover 13 are both connected to screws 15 by threads. The rod of the screw 15 is connected to the positioning hole 14 by threads to prevent the cover from shifting or loosening due to equipment vibration or collision, and to prevent the water sample in the sampling tank from being contaminated by the outside due to the loose cover.

[0026] During use, when sampling the purified water inside the purification tank 1, the first control valve 2 can be turned to obtain water from the purification tank 1 at its optimal state. Since the first control valve 2 is fixedly installed at the middle position on the right side of the purification tank 1, this allows sampling of the purified water. When the first control valve 2 is opened, the purified water inside the purification tank 1 can be discharged into the filter 3 through the first connecting pipe 4. Because the filter 3 has a filter element 6 fixedly installed inside, the water entering the filter 3 is filtered through the filter element 6. Simultaneously, the water is filtered through the right side wall of the purification tank 1. A delivery pipe 7 is fixedly installed, and the second connecting pipe 5 at the top of the delivery pipe 7 is connected to the lower end of the left side of the filter 3. This allows the sampled water source filtered in the filter 3 to be discharged into the delivery pipe 7 through the second connecting pipe 5, and then connected to the left side of the top of the sampling tank 9 through the lower end of the third connecting pipe 8. This allows the water source to be discharged again into the left side of the sampling tank 9 through the third connecting pipe 8. The combination of filtration and multiple pipelines greatly reduces the risk of introducing environmental microorganisms or particulate contamination during the sampling process, and makes the sampling process more convenient and faster. When water enters the inner cavity at the left end of the sampling tank 9, a filter plate 11 is fixedly installed there. This filter plate 11 can further filter the water entering the sampling tank 9. The inner cavity at the left end of the sampling tank 9 is set in an inclined state, and through holes 16 are arrayed at the left end of the sampling tank 9. At the same time, partition plates 10 are fixedly installed at both the front and rear ends of the inner cavity at the right end of the sampling tank 9. This partition plate 10 can divide the inner cavity at the right end of the sampling tank 9 into three independent areas. The water filtered by the filter plate 11 can be discharged into the independent cavity at the right end of the sampling tank 9 through the aperture of the through holes 16. Because the transparent cover plate 13 is initially placed on the outside of the sampling tank 9, the capacity of the water discharged into the cavity of the sampling tank 9 can be observed through the transparent cover plate 13. Multiple sampling cavities ensure that all test samples come from water samples from the same source at the same time, thereby achieving data synchronization and comparability. After a certain amount of water is discharged into the independent cavity on the right side of the sampling tank 9, the first control valve 2 can be turned again to close the connection between the purification tank 1 and the first control valve 2. Since the transparent cover 13 is initially attached to the outside of the sampling tank 9 by screws 15, the screws 15 can be turned to unscrew the screw rods from the positioning hole 14, thereby releasing the fixation between the sliding groove 12 and the transparent cover 13. Then, the transparent cover 13 is pulled to slide within the sliding groove 12, exposing the purified water in the independent cavity of the sampling tank 9. This allows for sampling of the purified water in multiple independent cavities of the sampling tank 9. After one round of sampling is completed, the transparent cover 13 can be pushed to slide within the sliding groove 12. Because the length of the transparent cover 13... The exposed dimension of the sampling tank 9 is larger than the right end of the sampling tank 9, so that the transparent cover plate 13 covers the outside of the sampling tank 9, thereby protecting the purified water in the cavity of the sampling tank 9. The screw 15 can be tightened again so that the shank of the screw 15 is connected to the diameter of the positioning hole 14 through the thread, and the sliding groove 12 is fixed together with the transparent cover plate 13, thereby protecting the sampling tank 9. At the same time, when the purified water in the sampling tank 9 is not used, the second control valve 17 installed in an array at the bottom of the sampling tank 9 can be tightened to drain the unused purified water in the cavity of the sampling tank 9. The cooperation between the transparent cover plate 13 and the sampling tank 9 can reduce the contact area and contact time between the water sample and the air, ensuring that the water sample taken out can truly reflect the original quality of the purified water in the storage tank.
