Description

Technical Field

[0001] This invention relates to the field of wastewater testing technology, specifically to an industrial wastewater testing device for environmental monitoring. Background Technology

[0002] Currently, industrial wastewater testing is mainly divided into two categories: laboratory offline testing and online real-time testing. Among them, detection technology based on optical detection principles has become the mainstream development direction in the field of online industrial wastewater testing due to its advantages such as fast detection speed, no secondary pollution, and non-contact detection. Its core is to use the optical properties of substances to absorb, scatter, and reflect light of specific wavelengths to achieve qualitative and quantitative analysis of pollutant components and concentrations in wastewater, which can cover a variety of key detection indicators such as COD (chemical oxygen demand), turbidity, heavy metal ions, and organic matter.

[0003] However, existing industrial wastewater detection devices still have many technical drawbacks. These mainly manifest in two ways: firstly, detection accuracy is easily affected by interference. Industrial wastewater often contains a large amount of suspended particulate matter and colloidal impurities, which can scatter and block the detection light, leading to optical signal distortion and affecting the accuracy of pollutant concentration detection; secondly, calibration convenience is insufficient. Existing devices often require manual calibration after shutdown, which is cumbersome, time-consuming, and dependent on professional personnel, making calibration deviations prone to occur and affecting the consistency of detection results. Therefore, this invention proposes an industrial wastewater detection device for environmental monitoring. Summary of the Invention

[0015] In summary, the technical effects and advantages of this invention are as follows: In this invention, an inlet chamber and a measuring chamber are assembled along the length of the central part of the detection housing. An inlet filter screen is embedded on one side of the inlet chamber, and a throttling pump is installed between the inlet chamber and the measuring chamber. The inlet filter screen, with its funnel-shaped structure, can pre-treat floating objects in the wastewater, facilitating water flow and restricting floating objects. Combined with the throttling pump's control of the inlet flow rate, it can alleviate the cleanliness of the wastewater entering the measuring chamber, effectively intercept suspended impurities in the wastewater, reduce interference from impurities entering the detection area with optical detection accuracy, reduce wear on detection components, and extend the service life of the device.

Clamping plates are set at the bottom of the limiting cover plate corresponding to the positions of the light source emitting module and the light source receiving module, respectively, to fix the original positions of the light source emitting module and the light source receiving module. This reduces manual adjustment, lowers the difficulty of operation, avoids positioning deviations caused by manual adjustment, ensures accurate alignment of the detection optical path, and improves detection efficiency. The combination of the fixing cover plate and the limiting cover plate not only seals and waterproofs the inside of the detection housing, but also facilitates disassembly and maintenance of the device. The sealed structure can effectively prevent wastewater leakage from damaging internal electrical components and reduce the failure rate. The detachable design facilitates the later inspection and replacement of various components, reduces maintenance costs, and improves the practicality and ease of operation and maintenance of the device.

[0017] In this invention, viewing windows are provided on both sides of the water measuring chamber at positions corresponding to the light source emitting module and the light source receiving module. A sliding scraper is configured on one side of the viewing window. Prolonged use can affect the clarity of the viewing window. By using the sliding scraper structure to laterally move and scrape the viewing window to remove impurities, contaminants attached to the surface of the viewing window can be removed in a timely manner, avoiding light distortion caused by impurities, ensuring smooth optical detection, maintaining the stability of detection accuracy, eliminating the need for manual disassembly and cleaning, reducing manual maintenance workload, and lowering maintenance costs. At the same time, the scraping and cleaning process is smooth and gentle, without damaging the surface of the viewing window, extending the service life of the viewing window, further ensuring the long-term stable operation of the device, and improving the reliability and detection efficiency of the device.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] refer to Figures 1-8 The industrial wastewater testing device for environmental monitoring shown below has the following specific embodiment: Example 1 This embodiment is used to achieve precise optical detection of industrial wastewater, relying on the positional coordination of each component to ensure the stability of the optical path and the accuracy of detection. An inlet cavity 2 is fixedly installed inside the detection housing 1. A water measuring cavity 3 is integrally formed on one side of the inlet cavity 2. Transparent windows 301 are embedded on the inner walls of both sides of the water measuring cavity 3 to ensure that the detection light can pass through smoothly and fully interact with the wastewater sample. A limiting cover 5 is located on the side of the water measuring cavity 3 away from the detection housing 1. Two sets of symmetrical clamping plates 501 are integrally formed parallel to each other at the bottom of the limiting cover 5. The two sets of clamping plates 501 respectively embed and fix the light source emitting module 12 and the light source receiving module 14, so that the emitting end of the light source emitting module 12 corresponds to the receiving end of the light source receiving module 14, and respectively fits against the two side walls of the water measuring cavity 3, achieving precise alignment of the optical path without manual adjustment. A detachable fixing cover 4 is fitted onto the outside of the limiting cover 5. The fixing cover 4 is embedded and fixed to the inner wall of the detection housing 1, providing a sealing and protective function for the internal optical path components, preventing external impurities or moisture from affecting the stability of the optical path. During testing, the main control mechanism 10 controls the transmitter controller 1201 to start the light source emission module 12. The detection light emitted by the light source emission module 12 penetrates the viewing window 301 on one side of the water measuring chamber 3 and illuminates the wastewater sample inside the water measuring chamber 3. After being absorbed and scattered by the wastewater, the light penetrates the viewing window 301 on the other side and is captured by the light source receiving module 14. The receiver 1401 transmits the collected optical signal to the data coordination mechanism 9 to complete the optical detection of wastewater pollutants and ensure the accuracy of the detection data.

[0022] Example 2 In this embodiment, the coordinated positioning of each component ensures sample introduction stability and efficient drainage, adapting to the conventional process of industrial wastewater testing. The inlet chamber 2 is fixedly located in the middle of the detection housing 1. An inlet filter 6 is embedded in the side of the inlet chamber 2 opposite to the measuring chamber 3. The inlet filter 6 has a funnel-shaped structure, facilitating smooth wastewater entry while effectively intercepting floating impurities, achieving preliminary pretreatment of the wastewater. A fixing member 601 is fixedly embedded in the side of the inlet filter 6 opposite to the inlet chamber 2. The fixing member 601 is detachably embedded in the detection housing 1. A water-blocking plate 602 is integrally formed on the side of the fixing member 601 facing the inlet chamber 2. The water-blocking plate 602 extends into the interior of the inlet chamber 2 and fits tightly against the inner wall of the inlet chamber 2, achieving a sealed water-blocking effect and preventing wastewater leakage. A buffer groove 201 is formed at the top of the inner wall of the inlet chamber 2 facing the inlet filter 6 to buffer the impact force when wastewater enters, preventing water flow fluctuations from affecting subsequent testing. A throttling pump 202 is installed between the inlet chamber 2 and the measuring chamber 3, with one end extending into the measuring chamber 3 to precisely control the inlet flow rate and ensure the stability of the testing process. A drainage chamber 7 is integrally formed on the inner wall of the testing housing 1 facing the measuring chamber 3. A sealing block 702 is integrally formed on the side of the drainage chamber 7 facing the measuring chamber 3, and the sealing block 702 is tightly fitted into the measuring chamber 3 to ensure a tight seal. A drainage pump 701 is installed through the drainage chamber 7, and a drain outlet 104 is provided on the testing housing 1 corresponding to the position of the drainage pump 701. After testing, wastewater is pumped by the drainage pump 701 into the drainage chamber 7 and then discharged through the drain outlet 104, achieving efficient wastewater discharge.

[0023] Example 3 This embodiment is used to achieve automatic cleaning of the viewing window 301, avoiding the adhesion of impurities that affect the detection effect. Automated cleaning and maintenance are achieved through the positional coordination of the sliding scraper 13 and related components. The viewing window 301 is embedded in the inner walls of both sides of the water measuring chamber 3, corresponding to the positions of the light source emitting module 12 and the light source receiving module 14. The sliding scraper 13 is slidably mounted on the side of the viewing window 301 away from the water measuring chamber 3. A flexible scraper blade 1301 is embedded in the side of the sliding scraper 13 facing the viewing window 301. The flexible scraper blade 1301 is in close contact with the surface of the viewing window 301, ensuring cleaning effectiveness while avoiding damage to the viewing window 301. A moving block 1302 is fixedly installed on the side of the sliding scraper 13 away from the detection housing 1. A moving groove 502 is formed along the length of the limiting cover plate 5 corresponding to the position of the moving block 1302. A rotating shaft 1303 is rotatably installed on the inner wall of the moving groove 502. The rotating shaft 1303 passes through the moving block 1302 and is threadedly connected to the moving block 1302, used to drive the moving block 1302 to move the sliding scraper 13. A motor component 1304 is embedded on the side of the limiting cover plate 5 away from the rotating shaft 1303. The rotating end of the motor component 1304 extends into the moving groove 502 and is fixedly connected to the rotating shaft 1303, providing power for the movement of the sliding scraper 13. The side of the sliding scraper 13 away from the moving groove 502 is integrally formed with a folded plate. The water measuring chamber 3 has an auxiliary groove 302 at the position corresponding to the folded plate, which guides and limits the folded plate to ensure smooth movement of the sliding scraper 13. When the device is used for a long time and impurities adhere to the surface of the viewing window 301, the main control mechanism 10 controls the motor component 1304 to start. The motor component 1304 drives the rotating shaft 1303 to rotate, and the moving block 1302 moves laterally along the rotating shaft 1303, driving the sliding scraper 13 to move synchronously. The flexible scraper 1301 scrapes and cleans the surface of the viewing window 301, ensuring the transparency of the viewing window 301 and ensuring a smooth detection optical path.

[0024] Example 4 This embodiment utilizes a detachable connection design for each component to facilitate convenient inspection, cleaning, and replacement of internal parts, adapting to the routine maintenance needs of industrial equipment. The fixing cover 4 is detachably fitted onto the outside of the limiting cover 5. The outer wall of the fixing cover 4 is detachably embedded and fixed to the inner wall of the detection housing 1. A limiting plate 402 is integrally formed on the side of the fixing cover 4 facing the water inlet chamber 2. The limiting plate 402 fits tightly against the outer wall of the water inlet chamber 2, limiting and fixing the water inlet chamber 2 while ensuring a tight seal. The limiting cover 5 is detachably fitted to the water measuring chamber 3 and the detection housing 1. A sealing plate 503 is integrally formed on the side of the limiting cover 5 facing the water measuring chamber 3. The sealing plate 503 extends into the water measuring chamber 3 and is fixedly fitted to the inner wall of the water measuring chamber 3, achieving sealing protection while facilitating the removal of the limiting cover 5. The water inlet filter 6 is detachably embedded in the detection housing 1 via a fixing member 601, facilitating periodic disassembly, cleaning, or replacement to ensure the pretreatment effect. The transmission mechanism 8, data coordination mechanism 9, and main control mechanism 10 are all mounted on the bottom of the limiting cover plate 5 and are detachably connected to the limiting cover plate 5, facilitating the inspection and maintenance of each control mechanism. When the device requires maintenance, the fixing cover plate 4 can be removed first, and then the limiting cover plate 5 can be removed to inspect internal components such as the light source emitting module 12, the light source receiving module 14, and the sliding scraper 13; the fixing part 601 can be removed to remove the water inlet filter 6 for cleaning or replacement. The entire detection housing 1 does not need to be disassembled, making the operation convenient and reducing the difficulty and cost of maintenance.

[0025] Working principle of this invention: After the device is started, the energy storage mechanism 11 provides stable power support for each component, and the main control mechanism 10 starts to control the operation of the entire device. Industrial wastewater first enters the inlet chamber 2 through the inlet filter 6. The inlet filter 6 adopts a funnel-shaped structure, which can effectively intercept floating impurities in the wastewater, realize the preliminary pretreatment of wastewater, and avoid impurities entering the detection area and affecting the detection accuracy. The buffer tank 201 at the top of the inner wall of the inlet chamber 2 buffers the impact force when the wastewater enters, reducing the impact of water flow fluctuations on subsequent detection.

[0026] Under the control of the main control mechanism 10, the pretreated wastewater is precisely pumped from the inlet chamber 2 to the measuring chamber 3 by the throttling pump 202, ensuring uniform filling of the measuring chamber 3 and providing a stable sample environment for optical detection. The viewing windows 301 on both sides of the measuring chamber 3 ensure smooth penetration of the detection light, and the clamping plate 501 at the bottom of the limiting cover 5 fixes the light source emitting module 12 and the light source receiving module 14, so that the emitting and receiving ends of the two are precisely aligned to form a stable detection optical path.

[0027] During the optical path detection stage, the main control mechanism 10 activates the light source emission module 12 via the emission controller 1201. The detection light emitted by the light source emission module 12 penetrates through one side of the viewing window 301 and illuminates the wastewater sample in the water measurement chamber 3. After being absorbed and scattered by pollutants in the wastewater, the light penetrates through the other side of the viewing window 301 and is captured by the light source receiving module 14. The receiver-transmitter 1401 transmits the collected optical signal to the data coordination mechanism 9. After data processing, the detection data is transmitted to an external terminal via the transmission mechanism 8 and the transmission signal terminal 801, completing the wastewater pollutant detection.

[0028] During the inspection, if impurities adhere to the surface of the viewing window 301 due to long-term use, the main control mechanism 10 starts the motor component 1304. The motor component 1304 drives the rotating shaft 1303 to rotate. The moving block 1302, which is threadedly connected to the rotating shaft 1303, moves laterally along the moving groove 502, causing the sliding scraper 13 to move synchronously. The flexible scraper 1301 scrapes and cleans the surface of the viewing window 301, and the auxiliary groove 302 guides and limits the folding plate of the sliding scraper 13.

[0029] After the test is completed, the main control mechanism 10 starts the drainage pump 701 to pump the wastewater in the water measuring chamber 3 to the drainage chamber 7. The sealing block 702 ensures that the drainage chamber 7 and the water measuring chamber 3 are sealed together, and the wastewater is finally discharged through the drain outlet 104.

[0030] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
