Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to a more accurate method and apparatus for judging the settling performance of flocs. Background Technology

[0002] Currently, when using flocculation sedimentation in wastewater treatment, large amounts of polyaluminum chloride (PAC) or polyacrylamide (PAM) are typically added as flocculants. This causes settleable substances in the wastewater to agglomerate and form larger flocs during sedimentation, which are then separated from the water through sedimentation or flotation. During this process, it is usually necessary to observe the floc sedimentation process to assess its sedimentation performance and allow for subsequent improvements.

[0003] However, traditional indicators for assessing settling effectiveness generally include settling velocity, clarification zone height, clarification zone concentration, and sedimentation efficiency. Currently, these methods typically rely solely on real-time photography of the flowing water using camera units to observe the floc state during the settling process and thus determine settling performance. This observation and judgment method is relatively simplistic and cannot comprehensively reflect the actual settling situation of the flocs; the accuracy of the judgment results needs improvement. Therefore, further improvements are warranted. Summary of the Invention

[0004] In order to further improve the accuracy of floc settling performance assessment, this application provides a more accurate method and apparatus for assessing floc settling performance.

[0005] Firstly, this application provides a more accurate device for judging the settling performance of flocs, employing the following technical solution:

[0006] A more accurate floc settling performance assessment device includes a glass plate and a backlight plate arranged vertically opposite each other, with a water tank formed between the glass plate and the backlight plate for water to flow through; a camera unit is arranged on the outside of the glass plate for observing the flocculation and settling of the water flowing through the water tank through the glass plate; a vertically downward-facing syringe-shaped transparent tube is also arranged between the camera unit and the glass plate, and a water pipe is connected to the bottom of the syringe-shaped transparent tube, which can be used to pump or drain water.

[0007] By adopting the above technical solution, when conducting flocculation and sedimentation observation and evaluation, the entire device is partially submerged in water. On one hand, a camera unit takes real-time photos of the water flowing through the water tank through a glass plate. Since the water in the tank between the glass plate and the backlight plate is flowing, the real-time state of the flocs can be observed. On the other hand, water is pumped into a syringe-shaped transparent tube through a water pipe, and then the camera unit takes time-lapse photos of the water in the syringe-shaped transparent tube at intervals (e.g., 1 minute, 5 minutes, 10 minutes, 15 minutes) to observe the state of the flocs and the state of the supernatant. Therefore, through both real-time and time-lapse judgments, the results are more accurate.

[0008] Optionally, a piston head is provided inside the syringe-shaped transparent tube, and a first driving unit is provided at the top of the syringe-shaped transparent tube for controlling the piston head to move up and down.

[0009] By adopting the above technical solution, the first driving unit controls the piston head to move up and down. When the piston head moves up, water is drawn into the syringe-shaped transparent tube; when the piston head moves down, water is discharged from the syringe-shaped transparent tube.

[0010] Optionally, a first cleaning brush is also fixedly installed at the bottom of the piston head.

[0011] By adopting the above technical solution, during the water pumping process, the first cleaning brush moves up and down with the piston head to clean the inner wall of the syringe-shaped transparent tube.

[0012] Optionally, a second cleaning brush is installed between the glass plate and the backlight plate. The second cleaning brush is vertically arranged and is close to the glass plate and the backlight plate. The second cleaning brush can move along the space between the glass plate and the backlight plate and can move out of the water tank from one end of the water tank outlet.

[0013] By adopting the above technical solution, when cleaning is required, the second cleaning brush is controlled to move back and forth between the glass plate and the backlight plate to clean the two opposing inner surfaces of the glass plate and the backlight plate. After cleaning is completed, the second cleaning brush is moved out of the water tank from one end of the water tank outlet and stored on the outlet side of the water tank, thereby avoiding blocking the water flow and saving space.

[0014] Optionally, a guide rail is mounted on the back side of the backlight panel. The guide rail is horizontally arranged and includes a horizontal section and an arc-shaped section. The horizontal section extends from the inlet end of the water tank to the outlet end of the water tank. The arc-shaped section extends smoothly from the outlet end of the horizontal section near the water tank and extends away from the glass plate. A slide block is slidably mounted on the guide rail. A support is fixedly mounted on the top of the slide block. The support extends between the glass plate and the backlight panel. The top of the second cleaning brush is mounted on the support, and the second cleaning brush moves back and forth along the guide rail via a second drive unit.

[0015] By employing the above technical solution, during cleaning, the second cleaning brush is controlled to move back and forth along the horizontal section of the guide rail to clean the two opposing inner surfaces of the glass plate and the backlight plate. After cleaning is completed, the second cleaning brush is moved outward along the arc section of the guide rail and led back to the outlet side of the water tank.

[0016] Optionally, the second drive unit includes a motor; a rack is provided on the back of the backlight panel near the top position, the rack is arranged parallel to the guide rail, and the rack extends from one end of the guide rail to the other end of the guide rail; a gear is installed on the slide in the guide rail, the gear meshes with the rack, and the motor is used to drive the gear.

[0017] By adopting the above technical solution, the motor drives the gear, and under the transmission of the gear and rack, the second cleaning brush moves back and forth along the guide rail.

[0018] Optionally, the second cleaning brush is rotatably mounted on the support.

[0019] By adopting the above technical solution, since the second cleaning brush is rotatably mounted on the support, during the cleaning process, when the second cleaning brush moves from the horizontal section to the arc section, the second cleaning brush can rotate to adjust its posture when it enters the horizontal section later, so as to switch different parts to the positions that fit with the glass plate and the backlight plate, so as to make full use of the different positions of the second cleaning brush to complete the cleaning work.

[0020] Optionally, the inlet end of the water trough formed between the glass plate and the backlight plate is funnel-shaped.

[0021] By adopting the above technical solution, the inlet end of the water tank is funnel-shaped, which facilitates the flow of water into the water tank.

[0022] Secondly, this application provides a more accurate method for judging the settling performance of flocs, using the following technical solution:

[0023] A more accurate method for judging floc settling performance, based on the aforementioned more accurate floc settling performance judging device, is characterized by the following steps:

[0024] S1. Submerge the entire device halfway in the water. At this time, the glass plate and the backlight plate slice the water flow, and the water flows through the water channel formed between the glass plate and the backlight plate.

[0025] S2. Using a syringe-shaped transparent tube, water is simultaneously drawn into the syringe-shaped transparent tube;

[0026] S3. Using the camera unit, take real-time photos of the water flowing through the water tank through the glass plate to observe the real-time state of the flocs; at the same time, use the camera unit to take time-lapse photos of the water in the syringe-shaped transparent tube at intervals to observe the sedimentation state of the flocs over time.

[0027] S4. Combine the real-time photography results of the water tank and the time-delayed photography results of the syringe-shaped transparent tube by the camera unit to conduct combined observation and analysis to evaluate the settling effect, and judge its settling performance by its settling effect.

[0028] By adopting the above technical solution, during the observation and evaluation of flocculation and sedimentation, on the one hand, a camera unit takes real-time photos of the water flowing through the water tank through a glass plate. Since the water in the tank between the glass plate and the backlight plate is flowing, the real-time state of the flocs can be observed. On the other hand, water is pumped into a syringe-shaped transparent tube through a water pipe, and then the camera unit observes the state of the flocs and the supernatant in the syringe-shaped transparent tube at time intervals. Therefore, by combining the real-time photos of the water tank and the time-delayed photos of the syringe-shaped transparent tube, the sedimentation effect can be evaluated through combined observation and analysis, and the sedimentation performance can be judged based on the sedimentation effect, resulting in more accurate results.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. During flocculation and sedimentation observation and evaluation, the entire device is partially submerged in water. On one hand, a camera unit takes real-time photos of the water flowing through a water tank via a glass plate. Because the water in the tank between the glass plate and the backlight plate is flowing, the real-time floc state can be observed. On the other hand, water is pumped into a syringe-shaped transparent tube through a water pipe, and then the camera unit takes time-lapse photos of the water inside the syringe-shaped transparent tube at intervals (e.g., 1 minute, 5 minutes, 10 minutes, 15 minutes) to observe the floc state over these delays. Therefore, by combining real-time and time-lapse assessments, the results are more accurate.

[0031] 2. During the water pumping process, the first cleaning brush moves up and down with the piston head to clean the inner wall of the syringe-shaped transparent tube;

[0032] 3. When cleaning is required, control the second cleaning brush to move back and forth between the glass plate and the backlight plate to clean the two opposing inner surfaces of the glass plate and the backlight plate. After cleaning is complete, move the second cleaning brush out of the water tank from one end of the outlet and retract it to the outlet side of the water tank to avoid blocking the water flow and to save space.

[0039] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0040] This application discloses a more accurate floc settling performance judgment device.

[0041] Reference Figure 1 and Figure 2A more accurate floc settling performance judgment device includes a glass plate 1 and a backlight plate 2 arranged vertically opposite each other, with a water tank 3 formed between the glass plate 1 and the backlight plate 2 for water to flow through; a camera unit 4 is arranged on the outside of the glass plate 1 to observe the flocculation and settling of the water flowing through the water tank 3 through the glass plate 1; a vertically downward-facing syringe-shaped transparent tube 5 is also arranged between the camera unit 4 and the glass plate 1, and a water pipe 51 is connected to the bottom of the syringe-shaped transparent tube 5. The water pipe 51 is controlled to open and close by a valve (two-way valve) to pump or drain water.

[0042] During the flocculation and sedimentation observation and evaluation, the entire device is partially submerged in water. On one hand, camera unit 4 takes real-time photos of the water flowing through water tank 3 through glass plate 1. Since the water in water tank 3 between glass plate 1 and backlight plate 2 is flowing, the real-time floc state can be observed. On the other hand, water is pumped into a syringe-shaped transparent tube 5 through water pipe 51. Then, camera unit 4 takes time-lapse photos of the water in the syringe-shaped transparent tube 5 at intervals (e.g., 1 minute, 5 minutes, 10 minutes, 15 minutes) to observe the delayed floc state and the state of the supernatant. Therefore, by combining real-time and delayed assessments, the results are more accurate.

[0043] In addition, since the entire device is partially submerged in water during operation, with its top not submerged, the waterproofing level of some structures can be greatly reduced, saving costs.

[0044] Reference Figure 2 In this embodiment, the inlet 31 of the water tank 3 formed between the glass plate 1 and the backlight plate 2 is funnel-shaped, which facilitates the flow of water into the water tank 3.

[0045] Reference Figure 3 Specifically, in this embodiment, the top of the syringe-shaped transparent tube 5 is open, a piston head 52 is provided inside the syringe-shaped transparent tube 5, and a first driving unit 53 is provided at the top of the syringe-shaped transparent tube 5 to control the piston head 52 to move up and down. When the piston head 52 moves upward, water is drawn into the syringe-shaped transparent tube 5; when the piston head 52 moves downward, water is discharged from the syringe-shaped transparent tube 5.

[0046] Specifically, in this embodiment, the first driving unit 53 includes a cylinder, which is vertically and fixedly mounted on the top of the syringe-shaped transparent tube 5, and the top of the piston head 52 is connected to the piston rod end of the cylinder. The cylinder is used to control the piston head 52 to move up and down.

[0047] Reference Figure 3 In this embodiment, a first cleaning brush 54 is also fixedly installed at the bottom of the piston head 52. During the water pumping process, the first cleaning brush 54 moves up and down with the piston head 52 to clean the inner wall of the syringe-shaped transparent tube 5.

[0048] Reference Figure 2 In this embodiment, a second cleaning brush 6 is installed between the glass plate 1 and the backlight plate 2. The second cleaning brush 6 is vertically arranged and closely attached to the glass plate 1 and the backlight plate 2. The second cleaning brush 6 can move along the space between the glass plate 1 and the backlight plate 2, and can also exit the water tank 3 from one end of the outlet 32. When cleaning is required, the second cleaning brush 6 is controlled to move back and forth between the glass plate 1 and the backlight plate 2 to clean the two opposing inner surfaces of the glass plate 1 and the backlight plate 2. After cleaning is completed, the second cleaning brush 6 is moved out of the water tank 3 from one end of the outlet 32, so that it is stored on the outlet side of the water tank 3, thereby avoiding blocking the water flow and saving space.

[0049] Reference Figure 2 Specifically, in this embodiment, a guide rail 61 is installed on the back side of the backlight panel 2. The guide rail 61 is horizontally arranged and includes a horizontal section and an arc-shaped section. The horizontal section extends from one end of the inlet 31 of the water tank 3 to one end of the outlet 32 ​​of the water tank 3. The arc-shaped section extends smoothly in the horizontal section near the outlet 31 of the water tank 3 and extends in a direction away from the glass plate 1.

[0050] A slide block 62 is slidably mounted on the guide rail 61, and a support 63 is fixedly mounted on the top of the slide block 62. The support 63 extends between the glass plate 1 and the backlight plate 2. The top of the second cleaning brush 6 is mounted on the support 63, and the second cleaning brush 6 moves back and forth along the guide rail 61 through the second drive unit 64.

[0051] Reference Figure 4 Specifically, in this embodiment, the second drive unit 64 includes a motor 641; a rack 642 is provided on the back of the backlight panel 2 near the top position, the rack 642 is arranged parallel to the guide rail 61, and the rack 642 extends from one end of the guide rail 61 to the other end of the guide rail 61; a gear 643 is installed on the slide 62 in the guide rail 61, the gear 643 meshes with the rack 642, and the motor 641 is used to drive the gear 643.

[0052] During operation, motor 641 drives gear 643, which, through the transmission between gear 643 and rack 642, causes the second cleaning brush 6 to move back and forth along guide rail 61. During cleaning, the second cleaning brush 6 is controlled to move back and forth along the horizontal section of guide rail 61 to clean the two opposing inner surfaces of glass plate 1 and backlight plate 2. After cleaning, the second cleaning brush 6 is moved outward along the arc-shaped section of guide rail 61 and retracted to the outlet side of water tank 3.

[0053] In this embodiment, the second cleaning brush 6 is rotatably mounted on the support 63. Therefore, during the cleaning process, when the second cleaning brush 6 moves from the horizontal section to the arc section, the second cleaning brush 6 can rotate to adjust its posture when it subsequently enters the horizontal section, so as to switch different parts to the positions that fit with the glass plate 1 and the backlight plate 2, so as to make full use of the different positions of the second cleaning brush 6 to complete the cleaning work.

[0054] This application also discloses a more accurate method for judging the settling performance of flocs.

[0055] A more accurate method for judging floc settling performance, based on the aforementioned more accurate floc settling performance judging device, includes the following steps:

[0056] S1. The entire device is partially submerged in water. At this time, the glass plate 1 and the backlight plate 2 slice the water flow, and the water flows through the water tank 3 formed between the glass plate 1 and the backlight plate 2.

[0057] S2. Using the syringe-shaped transparent tube 5, water is simultaneously drawn into the syringe-shaped transparent tube 5;

[0058] S3. Using camera unit 4, take real-time photos of the water flowing through water tank 3 through glass plate 1 to observe the real-time floc state; at the same time, use camera unit 4 to take time-delayed photos of the water in syringe-shaped transparent tube 5 at intervals to observe the delayed floc state.

[0059] S4. Combining the real-time photography results of the water tank 3 and the delayed photography results of the syringe-shaped transparent tube 5 by the camera unit 4, the sedimentation effect is evaluated by combining observation and analysis, and the sedimentation performance is judged by its sedimentation effect.

[0060] During the flocculation and sedimentation observation and evaluation, on the one hand, camera unit 4 takes real-time photos of the water flowing through water tank 3 through glass plate 1. Since the water in water tank 3 between glass plate 1 and backlight plate 2 is flowing, the real-time floc state can be observed. On the other hand, water is pumped into syringe-shaped transparent tube 5 through water pipe 51, and then camera unit 4 observes the floc state of the water in syringe-shaped transparent tube 5 at time intervals. Therefore, by combining the real-time photo results of water tank 3 and the time-delayed photo results of syringe-shaped transparent tube 5, the sedimentation effect can be evaluated through combined observation and analysis, and the sedimentation performance can be judged based on the sedimentation effect, resulting in more accurate results.
