Description

Technical Field

[0001] This invention relates to the field of industrial wastewater detection technology, specifically to a sampling and detection device for industrial wastewater treatment. Background Technology

[0002] With the country's high emphasis on environmental protection, the detection of wastewater in industrial wastewater is particularly important to ensure the health and sustainable development of the water environment. Wastewater treatment plants must set up wastewater sampling points and water volume monitoring points at wastewater discharge outlets and the inlet and outlet of wastewater treatment facilities.

[0003] Because industrial wastewater is quite special, pollutants in the wastewater may precipitate, and the concentration of pollutants varies significantly at different depths. To improve the accuracy of water sample testing, it is necessary to sample water at different depths.

[0004] Meanwhile, traditional sampling devices cannot simultaneously record environmental parameters (such as temperature and pH value) during sampling, making it impossible to accurately measure environmental parameters and thus reducing the accuracy of sample detection.

[0005] Traditional devices can only sample raw wastewater, requiring separation and extraction in a laboratory, which reduces detection efficiency.

[0006] Therefore, it is necessary to design a sampling and testing device for industrial wastewater treatment that improves the diversity and efficiency of industrial wastewater sampling and testing. Summary of the Invention

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.

[0030] Please see Figure 1-8 The present invention provides a technical solution: a sampling and detection device for industrial wastewater treatment, including a support 1, the support 1 including a lower plate 2, a middle plate 3 and an upper plate 4, the lower plate 2 and the upper plate 4 are both horizontally arranged and vertically connected to the middle plate 3, wherein the lower plate 2 and the middle plate 3 are connected in an "L" shape, and the upper plate 4 and the middle plate 3 are connected in a "T" shape, and a parking opening 5 is provided on the middle plate 3, and a sampling component 6 is placed in the parking opening 5.

[0031] Lockable casters are provided at the four corners of the lower plate 2 to facilitate the movement and fixation of the entire device; a winch 7 is fixedly connected to the upper side of the lower plate 2. The winch is a conventional technology. An adjustment component is provided on the lower side of the upper plate 4. The cable end of the winch 7 is connected to the sampling component 6 through the adjustment component.

[0032] like Figure 2 The adjustment component includes a rotatable wheel 8, which is a "V" shaped wheel. The cable of the winch 7 first rotates around the wheel 8 before being detachably connected to the sampling component 6.

[0033] A housing 9 is provided on the outside of the rotating wheel 8. The housing 9 is a U-shaped channel steel structure. The rotating wheel 8 is located in the groove of the housing 9 and is rotatably connected to the housing 9.

[0034] The adjustment assembly also includes a lead screw 10, which is located on the lower side of the upper plate 4. The lead screw 10 is horizontally positioned, and one end of the lead screw 10 passes through the parking opening 5. A connecting block 11 is fixedly connected to the side of the housing 9 near the upper plate 4.

[0035] Both ends of the lead screw 10 are rotatably connected to fixed blocks 12. One end of the lead screw 10 that passes through the parking port 5 along the axis is provided with a drive motor 13. The drive motor 13 is fixedly connected to the lower plate 2. The output shaft of the drive motor 13 is coaxially fixedly connected to the lead screw 10, thereby driving the lead screw 10 to rotate through the drive motor 13.

[0036] like Figure 3A guide rail 14 is fixedly connected to the lower side of the upper plate 4. The guide rail 14 and the lead screw 10 are arranged parallel to each other. The cross-section of the guide rail 14 is dovetail-shaped. The connecting block 11 has a groove 15 corresponding to the guide rail 14. The groove 15 cooperates with the guide rail 14. The connecting block 11 is slidably connected to the guide rail 14. The connecting block 11 moves along the guide rail 14 under the drive of the lead screw 10, and finally drives the sampling component 6 to move horizontally.

[0037] The sampling component 6 includes a housing 16, on the top of which a universal lifting ring is detachably mounted. The end of the cable of the winch 7 is connected to the universal lifting ring via a hook.

[0038] like Figure 4 The shell 2 16 includes an upper part and a lower part. The upper part is cylindrical and the lower part is funnel-shaped. The upper and lower parts are integrally formed.

[0039] The shell 16 has a cavity 17, which is a funnel-shaped cavity. The lower end of the cavity 17 has a water inlet 18, which is a cylindrical cavity. A sampling tube 19 is installed inside the cavity 17. The lower end of the sampling tube 19 is fitted inside the water inlet 18 and is sealed to the water inlet 18.

[0040] like Figure 5 A plunger 20 is slidably installed inside the sampling tube 19. The plunger 20 is slidably connected to the inner wall of the sampling tube 19 in a sealed manner. An electric telescopic rod 21 is installed at the upper end of the sampling tube 19. The fixed end of the electric telescopic rod 21 is fixedly connected to the inner wall of the cavity 17. The output end of the electric telescopic rod 21 extends into the sampling tube 19 and is fixedly connected to the plunger 20. The electric telescopic rod 21 drives the plunger 20 to move upward, thereby drawing sewage into the sampling tube 19.

[0041] like Figure 6 The sampling tube 19 is provided with a centrifugation assembly at its lower part. The centrifugation assembly includes a rotating drum 22, which is a funnel-shaped structure. The rotating drum 22 is sleeved on the sampling tube 19 and is coaxially arranged with the sampling tube 19. The lower end of the rotating drum 22 is sealed and rotatably connected to the sampling tube 19. The upper end of the rotating drum 22 is provided with a cover plate 23. The sampling tube 19 passes through the cover plate 23 and is fixedly connected to the cover plate 23. The upper end of the rotating drum 22 is sealed and rotatably connected to the cover plate 23.

[0042] The rotating drum 22 has a second cavity 24, which is a funnel-shaped structure. The sampling tube 19 has an inlet 25 at the upper end of the second cavity 24, and a one-way valve 27 is installed inside the inlet 25. The sampling tube 19 has an outlet 28 at the lower end of the second cavity 24, and a one-way valve 29 is installed inside the outlet 28. An electric control valve 34 is installed at the end of the sampling tube 19 near the water inlet 18.

[0043] like Figure 4A storage component is provided inside the cavity 17. The storage component includes multiple storage groups, which are arranged along the axial direction of the sampling tube 19. Each storage group is provided with three storage cylinders 35, which are evenly distributed around the circumference of the sampling tube 19.

[0044] The storage cylinder 35 is set vertically, and the lower end of the inner cavity of the storage cylinder 35 is connected to the connecting pipe 36.

[0045] The connecting pipe 36 of the storage cylinder 35 passes through the cover plate 23 and communicates with the cavity 24. One-way valve 37 is fixedly connected to one end of the connecting pipe 36 located in the cavity 24.

[0046] One end of the connecting pipe 36 corresponding to the two storage cylinders 35 in the same storage group passes through the cover plate 23 and is located at the upper end of the cavity 24, while the other end of the connecting pipe 36 corresponding to the storage cylinder 35 passes through the cover plate 23 and is located at the bottom end of the cavity 24.

[0047] like Figure 7 The inner cavity of the storage cylinder 35 is slidably connected to a plunger 38, which is slidably and sealingly connected to the inner cavity of the storage cylinder 35. An electric telescopic rod 39 is provided at the end of the storage cylinder 35 away from the connecting pipe 36, and the fixed end of the electric telescopic rod 39 is fixedly connected to the outer wall of the storage cylinder 35.

[0048] The output end of the electric telescopic rod 39 is inserted into the inner cavity of the storage cylinder 35 and fixedly connected to the plunger 38. The electric telescopic rod 39 drives the plunger 38 to move. Under the action of the plunger 38, the sewage in the cavity 24 enters the storage cylinder 35 through the one-way valve 37.

[0049] Each storage group in cavity 17 is fixedly connected to a fixed disk 40. The sampling tube 19 passes through the fixed disk 40 and is fixedly connected to the fixed disk 40. The fixed disk 40 has a mounting hole 41 for the storage tube 35. The storage tube 35 is fitted into the mounting hole 41 and is fixedly connected to the fixed disk 40.

[0050] Multiple thermoelectric cooling pads are attached to the outside of the storage cylinder 35. The multiple thermoelectric cooling pads are evenly distributed around the center of the storage cylinder 35. The thermoelectric cooling pads are used to preserve the sewage sample stored in the storage cylinder 35 at low temperature to avoid water quality deterioration caused by temperature changes.

[0051] The lower end of the housing 16 is detachably connected to a filter assembly 43, which is used to filter impurities in the wastewater when the sampling tube 19 is sampling.

[0052] like Figure 8The filter assembly 43 includes a housing 3 44, which is a cylindrical housing with openings at both ends. The housing 3 44 has a cavity 3 45, which is a cylindrical cavity. An external thread is provided on the outer wall of one end of the housing 3 44, and an internal thread is provided on the inner wall of the end of the water inlet 18 away from the cavity 1 17. The external thread and the internal thread are screwed together, thereby fixing the housing 3 44 to the housing 2 16.

[0053] The cavity 3 45 is equipped with a first filter screen 46 and a second filter screen 47. The first filter screen 46 is located on the side of the second filter screen 47 away from the housing 2 16, and the first filter screen 46 is located at the end of the cavity 3 45.

[0054] The first filter screen 46 is a grid-shaped filter screen used to block large suspended particles from entering, and the second filter screen 47 is a nanoporous filter screen used to prevent large suspended particles from entering.

[0055] like Figure 4 A pulley 30 is fitted on the outer wall of the rotating drum 22 and is fixedly connected to the rotating drum 22. A drive motor 31 is installed in the cavity 45 and is fixedly connected to the upper side of the lowest fixed plate 40. The output end of the drive motor 31 passes through the fixed plate 40 and is fixedly connected to a pulley 32. The pulley 30 and the pulley 32 are connected. The rotating drum 22 is driven to rotate by the drive motor 31, thereby centrifuging the sewage in the rotating drum 22.

[0056] An independent power supply 42 is installed inside the housing 2 16. The independent power supply 42 is fixedly connected to the upper side of the bottommost fixed plate 40. The drive motor 2 31, the electric telescopic rod 2 39 and the electric telescopic rod 1 21 are all powered by the independent power supply 42.

[0057] A pH sensor, a turbidity sensor, a conductivity sensor, and a temperature sensor are embedded on the outer wall of the cylindrical part at the lower end of housing 2 16. The pH sensor, turbidity sensor, conductivity sensor, and temperature sensor are all connected to a processor, which is located inside housing 2 16.

[0058] Specifically, the cylindrical part at the lower end of the shell 16 has multiple standardized interfaces on its outer wall. In addition to embedding pH sensors, turbidity sensors, conductivity sensors and temperature sensors, it can also be expanded to embed detection probes such as dissolved oxygen and heavy metal ions. In this way, the plug-and-play modular design can meet diverse monitoring needs.

[0059] Each storage cylinder 35 is connected to a liquid outlet pipe 33 via a three-way valve at one end near the connecting pipe 36. The end of the liquid outlet pipe 33 away from the storage cylinder 35 is connected to a one-way valve 26. The one-way valve 26 is fixedly connected to the housing 16. The output end of the one-way valve 26 extends out of the housing 16 and is sealed to the housing 16.

[0060] In this embodiment, the device is moved to the side of the sewage tank, the casters are locked, and the drive motor 13 is started. The drive motor 13 drives the lead screw 10 to rotate, which in turn drives the connecting block 11 to move horizontally along the guide rail 14. The winch 7 is started, and the cable is released synchronously with the connecting block 11, so that the sampling component 6 is moved out of the parking port 5 and suspended above the sewage tank.

[0061] The winch 7 continues to release the cable, and the sampling component 6 enters the sewage tank vertically downwards. After the inlet 18 of the sampling component 6 is submerged in sewage, the winch 7 stops operating, and the sampling component 6 samples and tests the sewage on the upper surface of the sewage.

[0062] Wastewater samples collected at the same depth are placed in the same storage group. The bottommost storage group in the sampling component 6 corresponds to the wastewater at the top of the wastewater pool. Similarly, the storage groups in the sampling component 6 from bottom to top correspond to the wastewater at different depths in the wastewater pool, from shallow to deep.

[0063] After the first sampling is completed, and after each subsequent sampling and testing, the winch 7 is controlled by the encoder of the winch 7 to release a fixed length of cable, so that the sampling component 6 descends to a fixed depth, thereby sampling and testing sewage at different depths in the sewage tank.

[0064] During each sampling, the pH sensor, turbidity sensor, conductivity sensor, and temperature sensor can all perform numerical detection on the wastewater at the current depth and transmit the data to the processor for storage.

[0065] Each time a sample is taken, the electric control valve 34 is opened first, and then the output end of the electric telescopic rod 21 is controlled to drive the plunger 20 to move upward. Under the action of negative pressure, the sewage in the sewage tank enters the sampling tube 19 through the filter assembly 43.

[0066] When the plunger 120 moves upward to its limit, the control valve 34 is closed. Then the plunger 120 is moved downward. Under pressure, the sewage in the sampling tube 19 enters the cavity 345 through the one-way valve 127.

[0067] The output end of the electric telescopic rod 39 of the corresponding storage cylinder 35 at the upper end of the cavity 24 of the connecting pipe 36 in the corresponding storage group is retracted, causing the plunger 38 to move upward. Under the action of negative pressure, the sewage in the cavity 45 enters the storage cylinder 35 through the one-way valve 37, thereby extracting and storing the original sewage in the cavity 45. According to the sewage temperature at this depth detected by the temperature sensor, all the semiconductor cooling chips in the corresponding storage group are controlled to maintain the temperature at the corresponding temperature, thereby keeping the temperature of the sewage in the storage group the same as the temperature at the same depth in the sewage pool and preventing the sewage from deteriorating.

[0068] After the storage cylinder 35 has stored the raw wastewater, the drive motor 31 is started to rotate. The drive motor 31 drives the rotating cylinder 22 to rotate at the corresponding speed according to the turbidity of the wastewater detected by the turbidity sensor, as follows:

[0069] The actual turbidity of the wastewater detected by the turbidity sensor is preset by the processor and denoted as D.

[0070] When D < 100 NTU, the rotation speed of the rotating drum 22 is 8000 rpm, and the rotation time is 2 min;

[0071] When 100 NTU < D < 500 NTU, the rotation speed of the rotating drum 22 is 12000 rpm, and the rotation time is 3 minutes;

[0072] When D > 500 NTU, the rotation speed of the drum 22 is 15000 rpm and the rotation time is 5 min.

[0073] Under the centrifugal action of the rotating drum 22, the sewage is separated into supernatant and turbid liquid. The output end of the electric telescopic rod 39 of the corresponding storage cylinder 35 at the upper end of the cavity 24 of the other connecting pipe 36 in the corresponding storage group is retracted, causing the plunger 38 to move upward. Under the action of negative pressure, the supernatant in the cavity 35 enters the storage cylinder 35 through the one-way valve 37, thereby extracting and storing the supernatant after the sewage in the cavity 35 has been centrifuged.

[0074] At the same time, the output end of the electric telescopic rod 39 of the corresponding storage cylinder 35 at the bottom of the cavity 24 of the connecting pipe 36 in the corresponding storage group is retracted, causing the plunger 38 to move upward. Under the action of negative pressure, the lower turbid liquid in the cavity 35 enters the storage cylinder 35 through the one-way valve 37, thereby extracting and storing the lower turbid liquid after the sewage centrifugation in the cavity 345.

[0075] Then, the plunger 20 is moved upward again. At this time, the solenoid valve 34 is still closed. Under the negative pressure of the sampling tube 19, the excess sewage in the cavity 45 enters the sampling tube 19 through the one-way valve 29. Finally, the solenoid valve 34 is opened, and the plunger 20 is moved downward again. Under the action of the plunger 20, the sewage that enters the sampling tube 19 from the cavity 45 is discharged through the filter assembly 43.

[0076] As the plunger 20 moves downward, it can squeeze and discharge the sewage attached to the sampling tube 19, thus avoiding cross-contamination when the sampling tube 19 samples sewage at different depths.

[0077] Meanwhile, the wastewater discharged from the sampling tube 19 can backwash the first filter screen 46 and the second filter screen 47 of the filter assembly 43, preventing the filter assembly 43 from becoming clogged after multiple samplings.

[0078] After the sampling component 6 completes the sampling of the sewage tank, the winch 7 is started to rotate in the reverse direction. The cable drives the sampling component 6 to rise. Then, the drive motor 13 is controlled to rotate in the reverse direction. The connecting block 11 moves and resets along the guide rail 14, so that the sampling component 6 moves back into the parking port 5.

[0079] Staff members place multiple test tubes of different depths and types in sequence at the valve ports of the one-way valve 26 where the corresponding connecting pipe 36 is located. They switch the three-way valve pipeline and control the output end of the corresponding electric telescopic rod 39 to extend. The plunger 38 squeezes the sewage, causing the sewage to be discharged from the valve port of the one-way valve 26 through the connecting pipe 36 and into the test tube, thereby completing the collection and transfer of sewage samples.
