Description

Technical Field

[0001] The invention relates to the technical field of water quality detection, in particular to a metal ion detection device for producing healthy drinking water. Background Art

[0002] With the acceleration of industrialization and the improvement of urbanization, water pollution is becoming increasingly serious. Drinking water metal ion detection has not only become a top priority in environmental protection, but also a key link in ensuring drinking water safety and maintaining ecological balance. Through efficient and accurate metal ion detection devices, potential water pollution problems can be discovered and dealt with in a timely manner to ensure the safety of drinking water for the people.

[0003] At present, the detection of metal ions in drinking water mainly relies on laboratory analysis, and the commonly used determination 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] Existing technologies usually require sampling and sending it to a laboratory for testing, which is a time-consuming and inefficient process. In emergency situations, such as sudden water pollution incidents, it is impossible to obtain test results in time and take countermeasures quickly.

[0005] Laboratory analysis methods can usually only detect a single water sample and cannot achieve continuous monitoring. However, water pollution is often sudden and uncertain, requiring real-time monitoring and early warning. Therefore, existing technologies are difficult to meet the needs of continuous monitoring.

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

[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 technology. Summary of the invention

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

[0009] Sampling tube, used to take samples from water sources;

[0010] A spiral blade is rotatably disposed in the sampling tube and is used to push the water sample by rotation;

[0011] A detection tube, connected above the sampling tube, for containing and guiding the water sample transported by the spiral blade;

[0012] A photometric detection device, arranged on one side of the detection tube, for detecting the metal ion content in the water sample;

[0013] A drain pipe, connected above the detection pipe, for discharging the detected water sample;

[0014] A drainage hole is provided on one side of the upper portion of the drainage pipe and serves as an outlet for the water sample;

[0015] A driving motor, arranged above the drain pipe, for providing rotational power;

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

[0017] Furthermore, an upper turntable and a lower turntable are respectively rotatably arranged in the detection tube, the upper turntable and the lower turntable are fixedly connected to the rotating shaft, and a plurality of capillaries are fixedly distributed circumferentially between the upper turntable and the lower turntable.

[0018] Furthermore, a piston disc is slidably arranged in the drain pipe, the piston disc is in contact with the inner wall of the drain pipe, and a plurality of inner rods are fixed below the piston disc, and each inner rod is inserted into each capillary tube in turn.

[0019] Furthermore, bristles are distributed on the outer wall of the inner rod.

[0020] Furthermore, a central gear is rotatably arranged at the center of the piston disc, and the central gear is slidably sleeved on the outer wall of the rotating shaft;

[0021] A side gear is fixed to one end of each inner rod close to the piston plate, and each of the side gears is meshed with the central gear.

[0022] Furthermore, two guide rods are fixed in the drainage pipe, and the guide rods can slidably penetrate the central gear.

[0023] Furthermore, a limiting assembly is provided on the side wall of the upper part of the drain pipe, and the limiting assembly includes a wedge block, and the bottom of the wedge block is an inclined surface. The wedge block can be slidably embedded in the side wall of the drain pipe. An electromagnet is provided on the outer wall of the drain pipe, and a spring is provided between the electromagnet and the wedge block.

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

[0025] Furthermore, sealing rings are provided on the edges of the upper turntable and the lower turntable to ensure that the water sample will 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 disc and the inner wall of the drain pipe to reduce the friction resistance when the piston disc slides and prevent water sample leakage.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, the design of multiple circularly rotating capillaries allows each capillary to have a chance to fit with the photometric detection device, thereby receiving irradiation from the light source and detecting metal ions, which helps to reduce the problems of wear and contamination caused by long-term use of a single capillary, thereby improving the accuracy of detection. In addition, the water sample can be continuously transported to the detection tube and continuously detected through multiple capillaries, avoiding the problem 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 disc and multiple inner rods arranged in the device can brush the inner wall of the capillary tube up and down while the water sample is being transported, effectively preventing impurities in the water from adhering to the inner wall of the capillary tube and avoiding interference with the photometric detection results. 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 bristles can rotate circumferentially to 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 results.

[0030] In the present invention, the device realizes multiple functions through the same driving motor, including the transportation of water samples, the reversal of capillary tubes, and the use of water pressure to control the lifting and lowering of the piston disc for cleaning. When the water sample is pushed to the drain pipe by the spiral blade, the water pressure increases and pushes the piston disc to slide up and leave the detection range of the photometric detection device; when the spiral blade rotates in the opposite direction and the water sample is discharged downward, the water pressure decreases, the piston disc slides down under the action of gravity, and the inner rod goes deep into the capillary tube for cleaning. The structure is compact and light, and the driving structure is simple and efficient, so it is easy to place in deep groundwater for water extraction and detection.

DETAILED DESCRIPTION

[0037] See also Figure 1-Figure 5 In an embodiment of the present invention, a metal ion detection device for producing healthy drinking water is characterized by comprising:

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

[0039] A spiral blade 5 is rotatably disposed in the sampling tube 1 and is used to push the water sample by rotation;

[0040] A detection tube 2, connected above the sampling tube 1, for containing and guiding the water sample transported by the spiral blade 5;

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

[0042] A drain pipe 3, connected above the detection pipe 2, for discharging the detected water sample;

[0043] A drainage hole 8 is provided on one side of the upper portion of the drainage pipe 3 and serves as an outlet for the water sample;

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

[0045] The rotating shaft 6 is connected to the output end of the driving motor 7 , passes through the drainage pipe 3 and the detection pipe 2 , and is 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, and then drive the spiral blade 5 to rotate in the sampling tube 1, so as to transport 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 drainage hole 8 in the drainage pipe 3, thereby realizing the continuous water sample metal ion detection function.

[0047] See also Figure 2 In this embodiment, an upper turntable 22 and a lower turntable 21 are respectively rotatably arranged in the detection tube 2, and the upper turntable 22 and the lower turntable 21 are fixedly connected to the rotating shaft 6, and a plurality of capillaries 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 23 can be attached to the photometric detection device 4 in sequence;

[0049] The photometric detection device 4 is provided with a light source projected toward a capillary 23 near it. When a beam of infrared light with a continuous wavelength passes through the capillary 23, and the vibration frequency or rotation frequency of a metal ion in the water sample in the capillary 23 is the same as the frequency of the infrared light, the light of the wavelength is absorbed by the metal ion. By measuring the absorbance or luminescence intensity of light of a specific metal ion at a specific wavelength or within a certain wavelength range, the metal ion can be qualitatively and quantitatively analyzed.

[0050] In this embodiment, a piston disc 31 is slidably disposed in the drain pipe 3, and the piston disc 31 is in contact with the inner wall of the drain pipe 31. A plurality of inner rods 32 are fixed below the piston disc 31, and each inner rod 32 is sequentially inserted into each capillary tube 23;

[0051] The outer wall of the inner rod 32 is provided with bristles.

[0052] When the spiral blade 5 rotates, the water sample pushes the piston disc 31 upward to slide, 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 23, until the piston disc 31 slides up to the water outlet 8, and the water sample is discharged from the water outlet 8;

[0053] When the spiral blade 5 rotates in the opposite direction, the water sample is discharged downward, the piston plate 31 slides down under the action of gravity, and the inner rod 32 penetrates into the capillary 23. During the process, the bristles distributed on the outer wall of the inner rod 32 scrub the inner wall of the capillary 23 to prevent impurities in the water from adhering to the inner wall of the capillary 23 and causing errors in the detection results of the photometric detection device 4.

[0054] That is, by intermittently rotating the spiral blade 5 forward and reversely, the inner wall of the capillary 23 can be scrubbed 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 on the edges of the upper turntable 22 and the lower turntable 21 to ensure that the water sample will 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 disc 31 and the inner wall of the drain pipe 3 to reduce the friction resistance when the piston disc 31 slides and prevent water sample leakage.

[0067] The specific implementation includes:

[0068] After the device is started, the driving motor 7 starts to work, driving the rotating shaft 6 to rotate, and the rotating power of the rotating shaft 6 is transmitted to the spiral blade 5. The spiral blade 5 rotates in the sampling tube 1, pushing the water sample to move upward. After the water sample passes through the sampling tube 1, it is transported to the detection tube 2 above. When the water sample enters the detection tube 2, it flows into each capillary 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 plate 31 to slide upward. When the piston plate 31 slides upward, the multiple inner rods 32 leave the detection range of the photometric detection device 4 to avoid blocking the water sample in the capillary 23. When the piston plate 31 slides upward to the water outlet 8, the water sample is discharged from the water outlet 8;

[0070] When the piston disc 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 disc 31 passes over the wedge block 91. When the piston disc 31 stops sliding upward, the upper part of the wedge block 91 abuts against the piston disc 31 to limit its downward movement, so that the inner rod 32 is at a position away from the detection range of the photometric detection device 4.

[0071] As the upper turntable 22 and the lower turntable 23 rotate, the plurality of capillaries 23 are sequentially attached to the photometric detection device 4, and the light source in the photometric detection device 4 is directed to a capillary 23 close to it, and the infrared light passes through the water sample in the capillary 23. The photometric detection device 4 performs qualitative and quantitative analysis of the metal ion by measuring the absorbance or luminescence intensity of the light at a specific wavelength or within a certain wavelength range.

[0072] After the detection is completed, the electromagnet 93 is energized to attract the wedge block 91, the piston disc 31 loses the restriction of the wedge block 91, the spiral blade 5 rotates in the opposite direction, the water sample is discharged downward, the piston disc 31 slides down under the action of gravity, the inner rod 32 penetrates into the capillary 23, and the bristles scrub the inner wall of the capillary 23 to prevent impurities in the water from adhering to the inner wall of the capillary 23;

[0073] Since the inner rod 32 is inserted into the capillary 23 and the side gear 33 is meshed with the center gear 43, when the capillary 23 rotates around the rotating shaft 6, the side gear 33 rotates around the center gear 43, so that each inner rod 32 and the bristles can rotate circumferentially to brush the inner wall of the capillary 23, further improving the cleaning effect.

[0074] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
