Description

Technical Field

[0001] The present invention relates to the technical field of water quality detection, and specifically to a metal ion detection device for the production of healthy drinking water. Background Art

[0002] With the acceleration of the industrialization process and the improvement of the urbanization level, the problem of water pollution has become increasingly severe. The detection of metal ions in drinking water has not only become the top priority of environmental protection work, but also a key link to ensure the safety of drinking water and maintain the ecological balance. Through an efficient and accurate metal ion detection device, potential water pollution problems can be discovered and handled in a timely manner to ensure the drinking water safety of the people.

[0003] Currently, the detection of metal ions in drinking water mainly relies on laboratory analysis. Common measurement methods include atomic absorption spectrometry (AAS), inductively coupled plasma mass spectrometry (ICP-MS), atomic fluorescence spectrometry (AFS), etc. These methods have the characteristics of high precision and high sensitivity, and can accurately determine the concentration of heavy metal ions in water samples.

[0004] The existing technology usually requires sampling and sending it to the laboratory for testing. This process takes a long time and is inefficient. In case of an emergency, such as a sudden water pollution incident, the test results cannot be obtained in a timely manner, and corresponding measures cannot be taken quickly.

[0005] The laboratory analysis method usually can only detect a single water sample and cannot achieve continuous monitoring. However, water pollution often occurs suddenly and unpredictably, and real-time monitoring and early warning are required. Therefore, the existing technology is difficult to meet the need for continuous monitoring.

[0006] To avoid cross-contamination and ensure the accuracy of test results, it is usually necessary to frequently replace test tubes or stop the test for cleaning. This process not only increases the operation complexity, but also reduces the detection efficiency. At the same time, frequently replacing test tubes also increases the cost.

[0007] Therefore, it is necessary to provide a metal ion detection device for the production of healthy drinking water to solve the problems raised in the above background art. Summary of the Invention

[0008] To achieve the above object, the present invention provides the following technical solution: A metal ion detection device for the production of healthy drinking water, comprising:

[0009] A sampling tube for sampling from a water source;

[0010] A spiral blade rotatably arranged in the sampling tube for pushing the water sample by rotation;

[0011] The detection tube is connected above the sampling tube and is used to accommodate and guide the water sample conveyed by the spiral blade;

[0012] The photometric detection device is arranged on one side of the detection tube and is used to detect the metal ion content in the water sample;

[0013] The drain pipe is connected above the detection tube and is used to discharge the detected water sample;

[0014] The water outlet hole is opened on one side of the upper part of the drain pipe and serves as the outlet of the water sample;

[0015] The driving motor is arranged above the drain pipe and is used to provide rotational power;

[0016] The rotating shaft is connected to the output end of the driving motor, penetrates through the drain pipe and the detection tube, and is fixedly connected to the spiral blade to transmit the rotational power of the driving motor to the spiral blade.

[0017] Further, an upper turntable and a lower turntable are rotatably arranged up and down in the detection tube. The upper turntable and the lower turntable are fixedly connected to the rotating shaft, and a plurality of capillary tubes are fixedly distributed circumferentially between the upper turntable and the lower turntable.

[0018] Further, a piston disk is slidably arranged in the drain pipe. The piston disk fits with the inner wall of the drain pipe. A plurality of inner rods are rotatably connected below the piston disk, and each inner rod is sequentially inserted into each capillary tube.

[0019] Further, brush hairs are distributed on the outer wall of the inner rod.

[0020] Further, a central gear is rotatably arranged at the center of the piston disk. The central gear is slidably sleeved on the outer wall of the rotating shaft;

[0021] One end of each inner rod close to the piston disk is fixed with a side gear, and each side gear meshes with the central gear.

[0022] Further, two guide rods are fixed in the drain pipe. The guide rods slidably penetrate through the central gear.

[0023] Further, a limiting component is arranged on the side wall of the upper part of the drain pipe. The limiting component includes a wedge block. The lower part of the wedge block is an inclined surface. The wedge block is slidably embedded into the side wall of the drain pipe. An electromagnet is arranged on the outer wall of the drain pipe, and a spring is arranged between the electromagnet and the wedge block.

[0024] Further, a heating pipe and a temperature sensor are arranged in the detection tube.

[0025] Furthermore, sealing rings are provided at the edges of the upper turntable and the lower turntable to ensure that the water sample does not leak from the gap between the turntable and the detection tube during the rotation of the turntable.

[0026] Furthermore, a wear-resistant sealing ring is provided between the piston disk and the inner wall of the drain pipe to reduce the frictional resistance when the piston disk slides and prevent the water sample from leaking at the same time.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] In the present invention, the design of multiple circumferentially rotating capillary tubes enables each capillary tube to have the opportunity to fit with the photometric detection device, so as to receive the irradiation of the light source and detect metal ions, which helps to reduce problems such as wear and pollution caused by the long-term use of a single capillary tube, thereby improving the accuracy of detection. Moreover, the water sample can be continuously transported into the detection tube and continuously detected through multiple capillary tubes, avoiding the problems of frequent replacement of test tubes or stopping detection for cleaning in traditional detection methods, and realizing a continuous and stable detection process.

[0029] In the present invention, the piston disk and multiple inner rods provided in the device can brush the inner wall of the capillary tube up and down while transporting the water sample, effectively preventing impurities in the water from sticking to the inner wall of the capillary tube and avoiding interference with the photometric detection result. Through the meshing design of the side gear and the central gear, when the capillary tube rotates around the rotating shaft, the inner rod and the brush can rotate to circumferentially brush the inner wall of the capillary tube, further improving the cleaning effect. This automatic cleaning function ensures the accuracy and reliability of the detection result.

[0030] In the present invention, the device realizes multiple functions through the same driving motor, including the transportation of the water sample, the commutation of the capillary tube, and the use of water pressure to control the lifting of the piston disk for cleaning. When the water sample is pushed by the spiral blade to the drain pipe, the water pressure increases to push the piston disk to slide upward and leave the detection range of the photometric detection device; when the spiral blade rotates in the reverse direction and the water sample is discharged downward, the water pressure decreases, and the piston disk slides downward under the action of gravity, and the inner rod penetrates into the capillary tube for cleaning. The structure is compact, lightweight, and the driving structure is simple and efficient, so it is convenient to place it at the deep groundwater to draw water and detect.

[0037] Please refer to Figures 1-5 , in an embodiment of the present invention, a metal ion detection device for the production of healthy drinking water, characterized by comprising:

[0038] Sampling tube 1, used for sampling from a water source;

[0039] Spiral blade 5, rotatably arranged in the sampling tube 1, used for pushing the water sample by rotation;

[0040] Detection tube 2, connected above the sampling tube 1, used for accommodating and guiding the water sample conveyed by the spiral blade 5;

[0041] Photometric detection device 4, arranged on one side of the detection tube 2, used for detecting the metal ion content in the water sample;

[0042] Drain pipe 3, connected above the detection tube 2, used for discharging the detected water sample;

[0043] Water outlet hole 8, opened on one side of the upper part of the drain pipe 3, serving as the outlet of the water sample;

[0044] Driving motor 7, arranged above the drain pipe 3, used for providing rotational power;

[0045] Rotating shaft 6, connected to the output end of the driving motor 7, passing through the drain pipe 3 and the detection tube 2, and fixedly connected to the spiral blade 5 to transmit the rotational power of the driving motor 7 to the spiral blade 5.

[0046] Among them, the driving motor 7 can drive the rotating shaft 6 to rotate, thereby driving the spiral blade 5 to rotate in the sampling tube 1 to convey the water sample at the lower end of the sampling tube 1 to the detection tube 2. After the water sample is detected by the photometric detection device 4, it is discharged through the water outlet hole 8 in the drain pipe 3, so as to realize the continuous function of detecting metal ions in the water sample.

[0047] Please refer to Figure 2 , in this embodiment, an upper turntable 22 and a lower turntable 21 are respectively rotatably arranged up and down in the detection tube 2. The upper turntable 22 and the lower turntable 21 are fixedly connected to the rotating shaft 6, and a plurality of capillary tubes 23 are fixedly distributed circumferentially between the upper turntable 22 and the lower turntable 21.

[0048] By rotating the upper turntable 22 and the lower turntable 21, each capillary tube 23 can be sequentially attached to the photometric detection device 4;

[0049] A light source is arranged in the photometric detection device 4 and projects towards one of the capillary tubes 23 close to it. When a beam of infrared light with continuous wavelengths passes through the capillary tube 23, when the vibration frequency or rotation frequency of a certain metal ion in the water sample in the capillary tube 23 is the same as the frequency of the infrared light, the light of this wavelength is absorbed by the metal ion. By measuring the absorbance or luminescence intensity of the light of a specific metal ion at a specific wavelength or within a certain wavelength range, qualitative and quantitative analysis of the metal ion can be carried out.

[0050] In this embodiment, a piston disk 31 is slidably arranged in the drain pipe 3. The piston disk 31 is attached to the inner wall of the drain pipe 3, and a plurality of inner rods 32 are rotatably connected below the piston disk 31. Each inner rod 32 is sequentially inserted into each capillary tube 23;

[0051] Brush hairs are distributed on the outer wall of the inner rod 32.

[0052] When the spiral blade 5 rotates, the water sample pushes the piston disk 31 to slide upward, so that the inner rod 32 leaves the detection range of the photometric detection device 4 to avoid blocking the water sample in the capillary tube 23 until the piston disk 31 slides up to the water outlet hole 8, and the water sample is discharged from the water outlet hole 8;

[0053] When the spiral blade 5 rotates in the reverse direction, the water sample is discharged downward, and the piston disk 31 slides downward under the action of gravity. The inner rod 32 extends into the capillary tube 23. During the process, the brush hairs distributed on the outer wall of the inner rod 32 brush the inner wall of the capillary tube 23 to avoid impurities in the water sticking to the inner wall of the capillary tube 23 and causing errors in the detection results of the photometric detection device 4;

[0054] That is to say, by intermittently rotating the spiral blade 5 in the forward and reverse directions, the inner wall of the capillary tube 23 can be brushed up and down.

[0055] In this embodiment, a central gear 34 is rotatably disposed at the center of the piston disc 31, and the central gear 34 is slidably sleeved on the outer wall of the rotating shaft 6;

[0056] A side gear 33 is fixed to one end of each inner rod 32 close to the piston plate 31 , and each side gear 33 is meshed with the central gear 34 .

[0057] That is, when the side gears 33 rotate around the central gear 34, each side gear 33 and each inner rod 32 can rotate, so that the bristles distributed on the outer wall of the inner rod 32 can rotate circumferentially to brush the inner wall of the capillary 23, thereby further improving the cleaning effect.

[0058] In this embodiment, two guide rods 35 are fixed in the drain pipe 3 , and the guide rods 35 slidably penetrate the central gear 34 .

[0059] When the shaft 6 rotates, each capillary 23 is driven to rotate around the shaft 6 . Since each inner rod 32 is inserted into the capillary 23 , the inner rod 32 and the piston plate 31 also rotate accordingly, so that the side gear 33 rotates around the central gear 34 .

[0060] In this embodiment, a limiting assembly 9 is provided on the side wall of the upper part of the drain pipe 3, and the limiting assembly 9 includes a wedge block 91. The lower part of the wedge block 91 is an inclined surface. The wedge block 91 can be slidably embedded in the side wall of the drain pipe 3. An electromagnet 93 is provided on the outer wall of the drain pipe 3, and a spring 92 is provided between the electromagnet 93 and the wedge block 91.

[0061] When the piston disc 31 slides upward to the position of the stop assembly 9, since the lower side of the wedge block 91 is an inclined surface, the wedge block 91 can compress the spring 92 to make the piston disc 31 pass over the wedge block 91;

[0062] When the piston disc 31 stops sliding upward, it will be pressed against by the upper part of the wedge block 91 and restricted from sliding downward, so that the inner rod 32 is in a position away from the detection range of the photometric detection device 4. At this time, the inner rod 32 will not block the photometric detection device 4 when the shaft 6 rotates at will, so as to perform metal ion detection in the water sample;

[0063] After stopping the detection, the electromagnet 93 is energized to attract the wedge block 91. When the shaft 6 rotates in the opposite direction, the piston plate 31 loses the restriction of the wedge block 91 and slides downward, so that the inner rod 32 is inserted into the capillary 23 for cleaning.

[0064] In this embodiment, a heating tube and a temperature sensor are arranged in the detection tube 2. By controlling the temperature in the detection tube 2, it is ensured that the detected water sample will not be affected by the temperature.

[0065] In this embodiment, sealing rings are provided at the edges of the upper turntable 22 and the lower turntable 21 to ensure that the water sample does not leak from the gap between the turntable and the detection tube 2 during the rotation of the turntable.

[0066] In this embodiment, a wear-resistant sealing ring is provided between the piston disk 31 and the inner wall of the drain pipe 3 to reduce the frictional resistance when the piston disk 31 slides and prevent the water sample from leaking at the same time.

[0067] Specific implementation includes:

[0068] After the device is started, the drive motor 7 starts to work, driving the rotating shaft 6 to rotate. The rotational power of the rotating shaft 6 is transmitted to the spiral blade 5. The spiral blade 5 rotates in the sampling pipe 1, pushing the water sample upward. After the water sample passes through the sampling pipe 1, it is conveyed to the upper detection tube 2. When the water sample enters the detection tube 2, it flows into each capillary tube 23.

[0069] The spiral blade 5 continues to rotate, pushing the water sample upward into the drain pipe 3, and at the same time driving the piston disk 31 to slide upward. When the piston disk 31 slides upward, multiple inner rods 32 leave the detection range of the photometric detection device 4 to avoid blocking the water sample in the capillary tube 23. When the piston disk 31 slides upward to the water outlet hole 8, the water sample is discharged from the water outlet hole 8.

[0070] When the piston disk 31 slides upward to the position of the limit assembly 9, the inclined surface of the wedge block 91 causes the wedge block 91 to compress the spring 92, and the piston disk 31 passes over the wedge block 91. After the piston disk 31 stops sliding upward, the upper part of the wedge block 91 abuts against the piston disk 31, restricting its downward slide and keeping the inner rod 32 in a position where it is out of the detection range of the photometric detection device 4.

[0071] As the upper turntable 22 and the lower turntable 21 rotate, multiple capillary tubes 23 are sequentially attached to the photometric detection device 4. The light source in the photometric detection device 4 projects light onto a capillary tube 23 close to it. Infrared light passes through the water sample in the capillary tube 23, and the photometric detection device 4 qualitatively and quantitatively analyzes the metal ion by measuring the absorbance or luminescence intensity of light at a specific wavelength or within a certain wavelength range of the specific metal ion.

[0072] After the detection is completed, the electromagnet 93 is energized to adsorb the wedge block 91. The piston disk 31 loses the restriction of the wedge block 91. The spiral blade 5 rotates in the reverse direction, and the water sample is discharged downward. The piston disk 31 slides downward under the action of gravity, and the inner rod 32 extends into the capillary tube 23, and the brush bristles brush the inner wall of the capillary tube 23 to prevent impurities in the water from adhering to the inner wall of the capillary tube 23.

[0073] Since the inner rod 32 is inserted into the capillary 23 and the side gear 33 meshes with the central gear 34, when the capillary 23 rotates around the rotating shaft 6, the side gear 33 rotates around the central gear 34, causing each inner rod 32 and the bristles to rotate to circumferentially brush the inner wall of the capillary 23, further improving the cleaning effect.

[0074] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
