Description

Technical Field

[0001] The present invention relates to the technical field of water pollution detection, in particular to a solute detection instrument for water pollutants. Background Art

[0002] With the acceleration of industrialization and urbanization, a large number of chemical substances have entered rivers, lakes and groundwater in the form of ions, molecules or colloids, forming so-called "solute pollutants", that is, they exist in a dissolved state in the water body, such as nitrates, heavy metal ions, and active pharmaceutical ingredients. Since these substances are colorless and odorless and diffuse rapidly, traditional visual or sensory means are difficult to identify their existence and concentration changes. Once the accumulation exceeds the prescribed range limit, it will pose a potential risk to the ecosystem and human health. Therefore, it is necessary to use a water quality detector to measure the concentration level of these dissolved substances. Generally, the water body to be tested is tested by the probe of the water quality detector to obtain the concentration value of the solute pollutants in the water body; In natural water environments, in addition to solute pollutants, a large number of suspended pollutants are also widely distributed. Among them, cyanobacteria, as an important component of suspended matter, are widely present in water bodies. When the content of solute pollutants in water bodies increases, it will provide sufficient nutrients for the growth and reproduction of cyanobacteria, thereby promoting the proliferation of cyanobacteria. In the process of massive reproduction of cyanobacteria, oil film-like floating objects often form and cover the surface of the water body. In natural waters, areas with more oil films indicate that there are more solute pollutants in the water body of this area. Generally, water pumps are used to concentrate the water in this area, and then the solute pollutants therein are tested by water quality detectors. When conducting water quality testing on water bodies covered with oil films, such oil films will interfere with the optical detection probes of the water quality testing instruments. Specifically, the oil film will directly block the detection light path of the probe, causing the light to be unable to be transmitted along the expected path. For the optical detection probe, the oil film will also absorb, reflect or scatter the detection light, thereby changing the light intensity reaching the target solute in the water body, thereby affecting the accurate acquisition of the detection signal. In addition, long-term contact with the oil film will cause a deposit layer to gradually form on the surface of the probe. Even if the oil film is temporarily removed, the residual pollutants will continue to interfere with the subsequent measurement process. However, existing water quality testing instruments lack effective processing methods when dealing with the above problems, resulting in the test results being difficult to accurately reflect the concentration of solute pollutants in the water body.

[0003] In order to solve the above problems, this application proposes a solute detection instrument for water pollutants. Summary of the Invention

[0004] The present invention proposes a solute detection instrument for water pollutants, which solves the problem in related technologies that when detecting water bodies, the oil film in the water body blocks the optical probe light path of the water quality detection instrument, absorbs, reflects, and scatters light, changes the signal intensity, and easily forms a sediment layer that causes continuous interference.

[0015] The above technical solution of the present invention has the following beneficial technical effects: 1.

After the water floats up to contact the felt oil film, the pumping component stops pumping water, and the separation component drives the internal component to rotate, driving the oil removal component and the filtration and aeration component to operate. The stirring aeration component stirs and aerates the water, preventing component blockage, destroying the agglomeration of oily substances, and causing them to suspend on the surface of the water to avoid clogging of the filter cartridge. This process further optimizes water quality, facilitates the subsequent cleaning of oily stains by the felt oil film, reduces interference with detection caused by oily substances, ensures that the detection light accurately reaches the target solute, and improves the stability and accuracy of the detection signal. 3. In the present invention, the separation part drives the oil removal component to operate, and the felt oil film circulates on the surface of the water body, adheres to oily substances, and is promptly scraped off by the scraping part, so as to keep the felt oil film continuously cleaning the oily substances, ensuring that the oily substances on the surface of the water body are completely removed to avoid interference with detection. After cleaning, the water body is discharged through the drain pipe. During the discharge process, the water quality detector detects the concentration of solute pollutants in the water body. Since the oily substances have been effectively cleaned, the water quality detector can detect more accurately, thereby improving the accuracy and reliability of water quality detection, and solving the problem that the existing water quality detector lacks an effective treatment method under the interference of oily substances.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0019] like Figures 1-13 As shown, the solute detection instrument for water pollutants proposed by the present invention includes a housing 1, a separator 2, a filter aeration component 3, an oil removal component 4, a water quality detector 5, a scraper 7 and a pumping component 8; The separator 2 is mounted on the housing 1 and connected to a pumping member 8 for preliminary filtration of the water. The filter aeration component 3 is arranged in the box body 1 and is connected to the separator 2, and is used for secondary filtration and aeration of the water body; Openings 101 are provided on both sides of the housing 1. The oil removal assembly 4 is disposed within the housing 1 and above the filter aeration assembly 3. The oil removal assembly 4 is in transmission cooperation with the separator 2 and the filter aeration assembly 3, respectively. The oil removal assembly 4 includes a felt oil film 401 extending out of the two openings 101 and circulating on the surface of the water body. The scraper 7 is installed on the side of the box body 1 and is used to scrape the surface of the felt oil film 401; The bottom of the box body 1 is connected to a drain pipe 6, and a water quality detector 5 is installed on the drain pipe 6 for detecting the discharged water.

[0020] When testing the water body, the water body to be tested is pumped to the separation element 2 through the pumping element 8, and the separation element 2 is then operated to perform a preliminary filtration on the water body to remove larger impurities. The filtered water body enters the filter aeration component 3 for secondary filtration and aeration, so that the oily substances in the water body can float on the surface of the water body, reduce small particle impurities and improve the water body state. When the separation element 2 is in operation, it can drive the felt oil film 401 in the oil removal component 4 to circulate on the surface of the water body, and absorb surface oil through the felt oil film 401. When the felt oil film 401 is in operation, the scraping element 7 can timely scrape off the oil on the felt oil film 401 to ensure its continuous adsorption capacity. The treated water body is discharged through the drain pipe 6, and the water quality detector 5 performs solute detection on the discharged water body. The above design removes different types of impurities and oil in the water body through multi-stage processing, reduces interference with detection, and improves detection accuracy.

[0021] like Figure 2 、 Figure 5 and Figure 6 As shown, in this embodiment, the separation element 2 includes a separation box 21 and a separation cylinder 22. The separation box 21 is installed on the top of the box body 1, and the separation cylinder 22 is installed on the separation box 21. The bottom of the separation cylinder 22 is provided with a first filter hole distributed along its length and connected to the separation box 21. An auger 222 is provided in the separation cylinder 22, and a motor 221 is installed at one end of the separation cylinder 22. The output end of the motor 221 is connected to a shaft 223 that rotates through one end of the separation cylinder 22 and is connected to the auger 222. The other end of the separation cylinder 22 is connected to a drainage pipe 224. The bottom of the separation box 21 is connected to a guide pipe 211 that is connected to the filter aeration assembly 3.

[0022] When the water is sucked into the separation cylinder 22 through the pumping member 8, the motor 221 can drive the shaft 223 to drive the auger 222 to rotate, so that while the auger 222 transports the water, larger blue algae and suspended matter in the water are intercepted and discharged through the drainage pipe 224. The filtered water enters the separation box 21 through the first filter hole, and then enters the filter aeration component 3 through the guide pipe 211. This structure realizes the preliminary filtration of the water, removes larger impurities, and prevents them from entering the subsequent links to clog equipment or interfere with detection, thereby providing a relatively pure water sample for subsequent processing.

[0023] like Figure 2 and Figure 3As shown, in this embodiment, the water pumping component 8 includes a water pump 81 and a water pipe 82, and the two ends of the water pipe 82 are respectively connected to the top of one end of the separation cylinder 22 and the discharge end of the water pump 81; the water inlet end of the water pump 81 is connected to the pipeline extending into the water body, and the water pump 81 is running to pump the external water body to be tested into the separation cylinder 22 through the water pipe 82, providing the separation component 2 with a water sample to be processed.

[0024] like Figure 2 、 Figure 3 and Figure 7 As shown, in this embodiment, the filter aeration assembly 3 includes a filter cartridge 31 and an agitating aeration member 32. The filter cartridge 31 is installed at the bottom of the box body 1, and the guide pipe 211 is connected to the filter cartridge 31. The agitating aeration member 32 is installed inside the filter cartridge 31 and is in transmission cooperation with the oil removal assembly 4. When the separator 2 drives the oil removal assembly 4 to operate, the agitating aeration member 32 is driven to rotate. One end of the filter cartridge 31 is connected to a first drain pipe 311, and a valve body 312 is installed on the first drain pipe 311. A second filter hole is opened on the filter cartridge 31, and the diameter of the second filter hole is smaller than the diameter of the first filter hole; the guide pipe 211 sends the preliminarily filtered water to the filter cartridge 31. The oil enters the filter cartridge 31, and the filter cartridge 31 performs a secondary filtration on the water through the second filter hole to intercept small suspended particles. At the same time, the oil removal component 4 drives the stirring aeration component 32 to rotate, stirring the water in the filter cartridge 31 to prevent impurities from settling. The stirring aeration component 32 can also aerate the water when rotating, generating a large number of bubbles in the water, destroying the agglomeration of oily substances, making the oily substances better suspended on the surface of the water, avoiding the oily substances from adhering to the filter cartridge 31 and causing blockage, and can also be more easily processed by the subsequent oil removal component 4. After the entire water body is tested, the valve body 312 can be opened to discharge the small suspended particles intercepted in the filter cartridge 31.

[0025] like Figure 7 and Figure 8As shown, in this embodiment, the stirring aeration member 32 includes an aeration pipe 321, a stirring plate 322, an aeration hole 323 and a rotary joint 324. The aeration pipe 321 is arranged in the filter cartridge 31 along its length direction and is in transmission cooperation with the oil removal component 4. The aeration pipe 321 is installed with a stirring plate 322 located in the filter cartridge 31. The aeration pipe 321 is provided with a plurality of aeration holes 323 located in the filter cartridge 31. The rotary joint 324 is installed on the front of the box body 1, and one end of the aeration pipe 321 rotates through the front of the box body 1 and is connected to the rotating air outlet end of the rotary joint 324. 4 is connected to an air inlet pipe 325, and the air inlet pipe 325 is connected to an air pump 326; the gas generated by the air pump 326 enters the aeration pipe 321 through the air inlet pipe 325 and the rotary joint 324, and is then discharged into the water body in the filter cartridge 31 through the aeration hole 323 to achieve aeration. At the same time, the aeration pipe 321 rotates under the drive of the oil removal component 4, and the stirring plate 322 thereon stirs the water body. The bubbles generated by the above aeration can destroy the agglomeration of oily substances in the water body, making it easier to be processed by the subsequent oil removal component 4. The stirring enhances the fluidity of the water body, prevents impurities from being deposited in the filter cartridge 31, and ensures the filtration efficiency.

[0026] like Figure 2 、 Figure 3 and Figure 9 As shown, in this embodiment, the oil removal component 4 also includes a fixed block 41, a main rotating rod 42, a secondary rotating rod 43, two synchronous belts 44, a first transmission member 45 and a second transmission member 46. Two symmetrically arranged fixed blocks 41 are installed on both sides of the box body 1, and the opening 101 is located between the two fixed blocks 41. The main rotating rod 42 is rotatably connected between the two fixed blocks 41. The main rotating rod 42 is fixed with a main shaft roller 422 and two main pulleys 421 at both ends thereof. Two secondary rotating rods 43 are symmetrically installed in the box body 1 for rotation. There is a secondary shaft roller 432 and two secondary pulleys 431 at both ends thereof. Two synchronous belts 44 cooperate with the main pulleys 421 at both ends of the main shaft roller 422 and the secondary pulleys 431 at both ends of the secondary shaft roller 432, respectively, to form a circulating conveying structure for the surface layer of the water body in the box body 1. The felt oil film 401 is detachably connected between the two synchronous belts 44 and wound around the main shaft roller 422 and the secondary shaft roller 432. The main rotating rod 42 and the shaft rod 223 are transmitted and cooperated through the first transmission member 45, and the main rotating rod 42 and the aeration pipe 321 are transmitted and cooperated through the second transmission member 46.

[0027] While the motor 221 drives the shaft 223 to rotate, it drives the main rotating rod 42 to rotate through the first transmission member 45. The main pulley 421 on the main rotating rod 42 drives the secondary pulley 431 on the secondary rotating rod 43 to rotate through the synchronous belt 44, so that the main shaft roller 422 and the secondary shaft roller 432 operate synchronously, thereby driving the felt oil film 401 to circulate on the surface of the water body between the two openings 101 to absorb surface oil. At the same time, the main rotating rod 42 drives the aeration tube 321 to rotate through the second transmission member 46. The felt oil film 401 designed above circulates and absorbs oil, effectively removes oil on the surface of the water body, reduces interference with detection, and works in conjunction with other components to save power sources and improve equipment integration.

[0028] like Figure 12 As shown, in this embodiment, a plurality of slots distributed along the path of the synchronous belt 44 are provided on the inner side thereof, and a plurality of blocks 4011 are connected to the felt oil film 401, and the plurality of blocks 4011 are respectively interference fit with the plurality of slots. During installation, it is only necessary to insert the blocks 4011 on the felt oil film 401 into the slots provided on the inner side of the synchronous belt 44. During disassembly, it is only necessary to pull the blocks 4011 out of the slots to complete the disassembly and assembly of the felt oil film 401. In the face of different water qualities, different types of felt oil films 401 can be replaced.

[0029] like Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the first transmission member 45 includes a first driving wheel 451, a first driven wheel 452 and a first belt 453. The first driving wheel 451 is fixed on the shaft 223 and is located between the separation cylinder 22 and the motor 221. The first driven wheel 452 is fixed to one end of one of the main rotating rods 42. A first belt 453 is provided between the first driving wheel 451 and the first driven wheel 452. In the first transmission member 45, while the motor 221 drives the shaft 223 to rotate, the first driving wheel 451 on the shaft 223 drives the first driven wheel 452 on the main rotating rod 42 to rotate through the first belt 453, thereby realizing power transmission from the separation member 2 to the oil removal component 4.

[0030] The second transmission member 46 includes a second driving wheel 461, a second driven wheel 462 and a second belt 463. The second driving wheel 461 is fixed to one end of one of the main rotating rods 42, and the second driven wheel 462 is fixed to one end of the aeration tube 321 and is located between the aeration element 32 and the housing 1. A second belt 463 is provided between the second driving wheel 461 and the second driven wheel 462. When the main rotating rod 42 in the second transmission member 46 rotates, the second driving wheel 461 on the main rotating rod 42 drives the second driven wheel 462 on the aeration tube 321 to rotate through the second belt 463, thereby realizing power transmission from the oil removal assembly 4 to the aeration element 32.

[0031] like Figure 1 、 Figure 3 and Figure 11 As shown, in this embodiment, the scraping member 7 includes a collecting box 71, a scraping plate 72 and a water supply pump 73. The collecting box 71 is installed on the side of the box body 1 and is located below the felt oil film 401. The scraping plate 72 is installed on the collecting box 71 and is in contact with the surface of the felt oil film 401. The water supply pump 73 is installed at the bottom of the collecting box 71. The water inlet end of the water supply pump 73 is used to connect the cleaning liquid. The water outlet end of the water supply pump 73 is connected to a water supply pipe 731. One end of the water supply pipe 731 is connected to a flushing pipe 732 installed on the side of the box body 1. The flushing pipe 732 is connected to a cleaning nozzle 733 facing the contact between the scraping plate 72 and the felt oil film 401. One end of the collecting box 71 is connected to a second sewage pipe 711. When the felt oil film 401 circulates and contacts the scraper plate 72, the scraper plate 72 scrapes off the oil adsorbed on its surface and drops it into the collection box 71. The water supply pump 73 sprays the cleaning liquid from the cleaning nozzle 733 through the water supply pipe 731 and the flushing pipe 732 to flush the contact area between the scraper plate 72 and the felt oil film 401, ensuring that the oil is completely removed. The oil and cleaning waste liquid in the collection box 71 are discharged through the second drain pipe 711. The above design cleans the oil on the felt oil film 401 in time to ensure its continuous adsorption capacity. The cleaning device further improves the cleaning effect and prevents the residual oil from affecting the subsequent oil removal. In actual use, the water inlet end of the water supply pump 73 is connected to a liquid storage tank storing cleaning liquid through a pipeline.

[0032] like Figure 11 and Figure 13 As shown, in this embodiment, roller pressing portions 74 are installed on both sides of the scraping plate 72, and the two roller pressing portions 74 are pressed against the two synchronous belts 44 respectively; The roller pressing part 74 includes a movable rod 741, and movable rods 741 are rotatably installed on both sides of the scraping plate 72. Brackets 742 are fixed on the two movable rods 741. A torsion spring 744 is sleeved on the movable rod 741, and the two ends of the torsion spring 744 are respectively connected to the scraping plate 72 and the bracket 742. Guide wheels 743 are rotatably installed on the two brackets 742. The two guide wheels 743 respectively conflict with the two synchronous belts 44. When the synchronous belt 44 drives the felt oil film 401 to operate, the scraping plate 72 scrapes the oil on the surface of the felt oil film 401, and under the action of the torsion spring 744, the brackets 742 are rotated. The guide wheel 743 on the frame 742 always contacts the synchronous belt 44 and applies a pressing force to the synchronous belt 44. When the synchronous belt 44 rotates, the guide wheel 743 also rotates. When the block 4011 on the felt oil film 401 runs to the position of the scraper plate 72, the guide wheel 743 rolls on it, playing a tightening role. This effectively prevents the block 4011 on the felt oil film 401 from detaching from the slot provided in the synchronous belt 44 when the scraper plate 72 scrapes the oil on the surface of the felt oil film 401, thereby ensuring the stable fit between the felt oil film 401 and the synchronous belt 44. At the same time, the squeezing of the guide wheel 743 can remove the water sample attached to the slot connection, preventing the accuracy of the sample from being affected during the cyclic detection of the felt oil film 401.

[0033] like Figure 10 As shown, in this embodiment, a control valve 61 is installed on the drain pipe 6, and a filter disc 62 is connected to the top of the drain pipe 6. A third filter hole is provided on the filter disc 62, and the diameter of the third filter hole is smaller than the diameter of the second filter hole. The water quality detector 5 is installed with a probe 51 inserted into the drain pipe 6; after the water in the box body 1 is treated, the control valve 61 can be opened, and the treated water is filtered again through the third filter hole on the filter disc 62 and enters the drain pipe 6 to remove smaller particulate impurities and is discharged outward through the drain pipe 6. During the discharge process, the solute pollutants in the water can be detected by the probe 51 of the water quality detector 5.

[0034] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the bottom of the box body 1 is connected to a water outlet pipe 104, and a valve is installed on the water outlet pipe 104. A water level sensor 102 for monitoring the water level is installed in the box body 1. A controller 103 is installed on the back of the box body 1. The water level sensor 102, the motor 221, the air pump 326, the water quality detector 5, the control valve 61, the water supply pump 73, and the valve are all electrically connected to the controller 103. The water level sensor 102 is used to monitor the water level height in the box body 1. When the water level in the box body 1 rises to the position of contact with the felt oil film 401, the signal is transmitted to the controller 103. The controller 103 controls the water pump 81 to stop pumping water according to the water level information and the preset program. In the subsequent work process, the controller 103 can control the start and stop and operating status of components such as the motor 221, the air pump 326, the water quality detector 5, the control valve 61, the water supply pump 73, and the valve of the water outlet pipe 104, thereby realizing automatic control of the equipment, reducing manual operations, and improving detection efficiency and stability. After the water body is tested, clean water can be drawn into the separator 2 through the pumping member 8 to flush it, and the clean water can enter the filter aeration assembly 3 to clean the impurities therein. The cleaned sewage can be discharged through the first sewage pipe 311, and the sewage remaining in the box body 1 can be discharged through the outlet pipe 104.

[0035] In a specific embodiment, the main component of the felt oil film 401 is usually a hydrophobic substance with low surface tension, which can quickly spread on the surface of the water body to form a thin film. The formation of this thin film enables the felt oil film 401 to effectively cover the surface of the water body, thereby more effectively adhering to the oily substances on the surface of the water body.

[0036] In the specific embodiment, it should be specifically noted that in actual use, the present device can be used to extract water from different locations and depths within the water area using a pump 81 (the pumping end of the pump 81 extends into the water at different locations and depths within the water area through a pipe), according to actual needs, to achieve large-scale sampling. A preliminary rapid test is then performed using the probe 51 on the water quality detector 5 to record initial data. To ensure more accurate test data, each time a water sample is taken from different locations and depths within the water area, after the oil film is removed, a sampling container can be placed at the bottom of the drain pipe 6 to collect the water. This water can then be compared with the initial test results of the water quality detector 5 using methods such as chemical analysis to ensure data accuracy. Furthermore, this preliminary test method can quickly and accurately determine where the water quality in an area differs significantly from the standard water quality. Water samples with significant differences can then be promptly stored for further, more refined testing. Targeted sampling reduces the number of samples taken and reduces workload. Furthermore, by sampling the water discharged from the drain pipe 6, detailed testing can be performed directly thereafter, eliminating the need for operations such as impurity removal and filtration of a large number of samples one by one.

[0037] The specific working principle of the present invention is as follows: The water pump 81 pumps the water to be tested into the separation drum 22 through the water conduit 82. The motor 221 drives the shaft 223 to rotate the auger 222. The larger impurities in the water are transported by the auger 222 to the discharge pipe 224 for discharge. The preliminarily filtered water enters the separation box 21 through the first filter hole and then enters the filter drum 31 through the guide pipe 211. The filter cartridge 31 filters the water secondary through the second filter hole to intercept small particles of impurities. At the same time, the shaft 223 drives the main rotating rod 42 to rotate through the first transmission member 45. The main rotating rod 42 drives the aeration pipe 321 to rotate through the second transmission member 46. The air pump 326 supplies air to the aeration pipe 321 through the air inlet pipe 325 and the rotary joint 324. The air is discharged from the aeration holes 323 to achieve aeration. The stirring plate 322 stirs the water to prevent impurities from settling. The bubbles generated during aeration can better suspend the oily substances in the sewage on the surface of the water. When the water level sensor 102 detects that the water has reached a preset height and contacts the felt oil film 401, the controller 103 controls the water pump 81 to stop pumping water. When the main rotating rod 42 rotates, it drives the main pulley 421, which drives the secondary pulley 431 and the secondary rotating rod 43 to rotate through the synchronous belt 44, so that the felt oil film 401 circulates on the surface of the water body to absorb the surface oil. When the felt oil film 401 passes through the scraper 72, the oil is scraped off to the collection box 71. The water supply pump 73 flushes the joint through the water supply pipe 731, the flushing pipe 732 and the cleaning nozzle 733, and the waste liquid is discharged from the second sewage pipe 711. After the water in the box 1 is treated, the control valve 61 is opened, and the water is filtered through the filter disc 62 and enters the drain pipe 6. The probe 51 of the water quality detector 5 detects the concentration of soluble substances in the water. After the detection is completed, the controller 103 controls the valve of the water outlet pipe 104 to open and discharge the remaining water in the box 1. The first sewage pipe 311 can discharge impurities in the filter cartridge 31; The entire process coordinates the operation of various components through the controller 103 to achieve multi-stage filtration, oil removal, aeration and detection of the water body, greatly reducing the interference of impurities and oil pollution on the detection, and improving the accuracy and efficiency of detection.
