Description

Technical Field

[0001] The present application relates to the field of water treatment technology, and in particular to a more accurate method and device for judging floc sedimentation performance. Background Art

[0002] Currently, when using flocculation sedimentation methods for wastewater treatment, large amounts of polyaluminum chloride (PAC) or polyacrylamide (PAM) are typically added as flocculants to cause settleable substances in the wastewater to bind together during the sedimentation process, forming larger flocs that can then be separated from the water through sedimentation or flotation. During this process, it is often necessary to observe the floc settling process to assess its settling performance and facilitate subsequent improvements.

[0003] However, traditional indicators for evaluating settling performance generally include settling velocity, clarification zone height, clarification zone concentration, and sedimentation efficiency. Currently, these methods typically rely solely on real-time camera imaging of flowing water to observe the flocs during the settling process and determine their settling performance. This relatively limited observation and assessment method fails to fully reflect the actual floc settling status, and the accuracy of the assessment results needs to be improved. Therefore, further improvements are needed. Summary of the Invention

[0004] In order to further improve the accuracy of judging the floc settling performance, the present application provides a more accurate method and device for judging the floc settling performance.

[0005] In the first aspect, the present application provides a more accurate device for judging floc settling performance, which adopts the following technical solution: A more accurate device for judging the floc sedimentation performance, comprising a glass plate and a backlight plate arranged vertically opposite to each other, wherein a water trough for water to flow through is formed between the glass plate and the backlight plate; a camera unit is arranged on the outside of the glass plate for observing the flocculation and sedimentation of water flowing through the water trough through the glass plate; a syringe-shaped transparent tube is also arranged vertically downward between the camera unit and the glass plate, and the bottom of the syringe-shaped transparent tube is connected to a water pipe, through which water can be pumped or drained.

[0006] By adopting the above technical solution, when conducting flocculation sedimentation observation and assessment, the entire device is half-submerged in water. On the one hand, the camera unit uses a glass plate to take real-time photos of the water flowing through the water tank. Because the water in the water tank between the glass plate and the backlight panel 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. The camera unit then takes time-lapse photos of the water in the syringe-shaped transparent tube at intervals (for example, 1 minute, 5 minutes, 10 minutes, 15 minutes), observing the delayed floc state and the state of the supernatant. Therefore, the combination of real-time and time-lapse judgments can achieve more accurate results.

[0007] Optionally, a piston head is provided inside the syringe-shaped transparent tube, and a first driving unit is provided on the top of the syringe-shaped transparent tube for controlling the up and down movement of the piston head.

[0008] By adopting the above technical solution, the first driving unit is used to control the piston head to move up and down, and 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.

[0009] Optionally, a first cleaning brush is fixedly mounted on the bottom of the piston head.

[0010] By adopting the above technical solution, during the process of pumping and releasing water, the first cleaning brush moves up and down with the piston head to clean the inner wall of the syringe-shaped transparent tube.

[0011] Optionally, a second cleaning brush is installed between the glass plate and the backlight panel, the second cleaning brush is vertically arranged, and the second cleaning brush is close to the glass plate and the backlight panel; the second cleaning brush can move between the glass plate and the backlight panel, and the second cleaning brush can move out of the water tank from one end of the water tank outlet.

[0012] By adopting the above technical solution, when cleaning is needed, the second cleaning brush is controlled to move back and forth between the glass plate and the backlight panel to clean the two opposing inner surfaces of the glass plate and the backlight panel. 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 at the side of the water tank outlet, thereby avoiding blocking the water flow and saving space.

[0013] Optionally, a guide rail is installed on the back side of the backlight panel, and the guide rail is horizontally arranged. The guide rail includes a horizontal section and an arc section, and the horizontal section extends from one end of the water tank inlet to one end of the water tank outlet, and the arc section smoothly extends in the horizontal section close to the outlet end of the water tank, and the arc section extends away from the glass plate; a slide is slidably installed on the guide rail, and a support is fixedly installed on the top of the slide, and the support extends between the glass plate and the backlight panel, and the top end of the second cleaning brush is installed on the support, and the second cleaning brush moves back and forth along the guide rail through the second driving unit.

[0014] By adopting 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 panel. After cleaning, the second cleaning brush is moved outward along the curved section of the guide rail and is stored at the outlet side of the water tank.

[0015] Optionally, the second driving unit includes a motor; a rack is provided on the back side of the backlight panel near the top, the rack is provided 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 is engaged with the rack, and the motor is used to drive the gear.

[0016] By adopting the above technical solution, the motor drives the gear, and under the transmission of the gear and the rack, the second cleaning brush moves back and forth along the guide rail.

[0017] Optionally, the second cleaning brush is rotatably mounted on the support.

[0018] By adopting the above technical solution, since the second cleaning brush can be rotatably installed on the support, during the cleaning process, when the second cleaning brush moves out of the horizontal section to the arc section, the second cleaning brush can be rotated to adjust its posture when it subsequently enters the horizontal section, so as to switch different parts to a position that fits with the glass plate and the backlight panel, so as to make full use of the different positions of the second cleaning brush to complete the cleaning work.

[0019] Optionally, the inlet end of the water tank formed between the glass plate and the backlight plate is trumpet-shaped.

[0020] By adopting the above technical solution, since the inlet end of the water tank is trumpet-shaped, it is convenient for water to flow into the water tank.

[0021] Secondly, this application provides a more accurate method for judging floc settling performance, which adopts the following technical solution: A more accurate method for judging floc settling performance is based on the above-mentioned more accurate device for judging floc settling performance, and is characterized by comprising the following steps: S1. Half-immerse the entire device in 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; S2. Using a syringe-shaped transparent tube, pump water into the syringe-shaped transparent tube simultaneously; S3. Using a camera unit, take real-time photos of the water flowing through the water tank through the glass plate to observe the real-time floc state; at the same time, using the camera unit, take time-lapse photos of the water in the syringe-shaped transparent tube at intervals to observe the delayed floc sedimentation state; S4. Combine the real-time photographic results of the water tank and the time-lapse photographic results of the syringe-shaped transparent tube by the camera unit to observe and analyze the sedimentation effect, and judge the sedimentation performance based on the sedimentation effect.

[0022] By adopting the above technical solution, when conducting flocculation sedimentation observation and evaluation, on the one hand, the camera unit uses the glass plate to take real-time photos of the water flowing through the water tank. Since the water in the water 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 the syringe-shaped transparent tube through the water pipe, and then the camera unit uses the water in the syringe-shaped transparent tube to observe the delayed floc state and supernatant state at intervals. Therefore, by combining the real-time camera unit's photos of the water tank and the time-lapse photos of the syringe-shaped transparent tube, it is possible to conduct a combined observation and analysis to evaluate the sedimentation effect, thereby judging the sedimentation performance based on the sedimentation effect, and the results are more accurate.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When conducting flocculation sedimentation observation and assessment, the entire device is half-submerged in water. On the one hand, the camera unit is used to take real-time photos of the water flowing through the water tank through the glass plate. Since the water in the water 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. The camera unit then takes time-lapse photos of the water in the syringe-shaped transparent tube at intervals (for example, 1 minute, 5 minutes, 10 minutes, 15 minutes) to observe the delayed floc state. Therefore, the results can be more accurate through both real-time and time-lapse judgments. 2. During the process of pumping and draining water, the first cleaning brush moves up and down with the piston head to clean the inner wall of the syringe-shaped transparent tube; 3. When cleaning is needed, control the second cleaning brush to move back and forth between the glass plate and the backlight panel to clean the two opposing inner surfaces of the glass plate and the backlight panel. After cleaning, move the second cleaning brush out of the water tank from one end of the outlet and store it on the side of the outlet to avoid blocking the water flow and save space.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiments of the present application disclose a more accurate device for determining floc settling performance.

[0031] Reference Figure 1 and Figure 2 A more accurate device for judging the floc sedimentation performance includes a glass plate 1 and a backlight plate 2 arranged vertically opposite to each other, with a water trough 3 for water flowing through formed between the glass plate 1 and the backlight plate 2; a camera unit 4 is arranged on the outside of the glass plate 1, for observing the flocculation and sedimentation of water flowing through the water trough 3 through the glass plate 1; a syringe-shaped transparent tube 5 is also arranged vertically downward 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.

[0032] During flocculation and sedimentation observation and assessment, the entire device is half-submerged in water. Camera unit 4, through glass plate 1, takes real-time photos of water flowing through water tank 3. Because the water in water tank 3 between glass plate 1 and backlight panel 2 is flowing, the real-time state of the flocs can be observed. Furthermore, water is pumped into syringe-shaped transparent tube 5 via water pipe 51. Camera unit 4 then takes time-lapse photos of the water in syringe-shaped transparent tube 5 at intervals (e.g., 1 minute, 5 minutes, 10 minutes, or 15 minutes) to observe the delayed state of the flocs and the state of the supernatant. This allows for both real-time and delayed assessments, resulting in more accurate results.

[0033] In addition, since the entire device is half submerged in water when working, and its top is not submerged in water, the waterproof level of some structures can be greatly reduced, saving costs.

[0034] 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 in a trumpet shape to facilitate water to flow into the water tank 3.

[0035] Reference Figure 3 Specifically, in this embodiment, the top of the syringe-shaped transparent tube 5 is open, and a piston head 52 is disposed inside the syringe-shaped transparent tube 5. A first driving unit 53 is disposed at the top of the syringe-shaped transparent tube 5 for controlling the upward and downward movement of the piston head 52. 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.

[0036] Specifically, in this embodiment, the first drive unit 53 includes a cylinder, which is fixedly mounted vertically downward 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 upward and downward movement of the piston head 52.

[0037] Reference Figure 3 In this embodiment, a first cleaning brush 54 is fixedly mounted on the bottom of the piston head 52. During the water extraction 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.

[0038] Reference Figure 2In this embodiment, a second cleaning brush 6 is installed between the glass plate 1 and the backlight panel 2. The second cleaning brush 6 is arranged vertically and is in close contact with the glass plate 1 and the backlight panel 2. The second cleaning brush 6 can move between the glass plate 1 and the backlight panel 2 and can be moved out of the water tank 3 from one end of the outlet 32 ​​of the water tank 3. When cleaning is required, the second cleaning brush 6 is controlled to move back and forth between the glass plate 1 and the backlight panel 2 to clean the two opposing inner surfaces of the glass plate 1 and the backlight panel 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 ​​of the water tank 3 and stored on the side of the outlet of the water tank 3, thereby avoiding blocking the water flow and saving space.

[0039] 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 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 section smoothly extends to one end of the horizontal section close to the outlet 31 of the water tank 3, and the arc section extends in a direction away from the glass plate 1.

[0040] A slide 62 is slidably mounted on the guide rail 61, and a support 63 is fixedly mounted on the top of the slide 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 driving unit 64.

[0041] Reference Figure 4 Specifically, in this embodiment, the second driving unit 64 includes a motor 641; a rack 642 is provided on the back side of the backlight panel 2 near the top, the rack 642 is provided 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 is engaged with the rack 642, and the motor 641 is used to drive the gear 643.

[0042] During operation, motor 641 drives gear 643, which, in turn, drives rack 642, causing second cleaning brush 6 to move back and forth along guide rail 61. During cleaning, second cleaning brush 6 is controlled to move back and forth along the horizontal section of guide rail 61, cleaning the opposing inner surfaces of glass plate 1 and backlight panel 2. After cleaning, second cleaning brush 6 is guided outward along the curved section of guide rail 61, retracting toward the outlet of water tank 3.

[0043] 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 positions to the position of contact with the glass plate 1 and the backlight panel 2, thereby making full use of the different positions of the second cleaning brush 6 to complete the cleaning work.

[0044] The embodiments of the present application also disclose a more accurate method for determining floc settling performance.

[0045] A more accurate method for judging floc settling performance, based on the above-mentioned more accurate device for judging floc settling performance, comprises the following steps: S1. Half-immerse the entire device 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 channel 3 formed between the glass plate 1 and the backlight plate 2; S2, using the syringe-shaped transparent tube 5, the water is simultaneously pumped into the syringe-shaped transparent tube 5; S3. Using the camera unit 4, take real-time photos of the water flowing through the water tank 3 through the glass plate 1 to observe the real-time floc state; at the same time, using the camera unit 4, take time-delayed photos of the water in the syringe-shaped transparent tube 5 at intervals to observe the delayed floc state; S4. Combine the real-time photographic results of the water tank 3 taken by the camera unit 4 and the time-delay photographic results of the syringe-shaped transparent tube 5 to observe and analyze the sedimentation effect, and judge the sedimentation performance based on the sedimentation effect.

[0046] During the flocculation and sedimentation observation and evaluation, on the one hand, camera unit 4 is used to take 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. Then, camera unit 4 is used to observe the water in syringe-shaped transparent tube 5 at intervals to observe the delayed floc state. Therefore, by combining the real-time photos of water tank 3 taken by camera unit 4 with the delayed photos of syringe-shaped transparent tube 5, the sedimentation effect can be combined and analyzed to evaluate the sedimentation effect, thereby judging the sedimentation performance based on the sedimentation effect, and the results are more accurate.

[0047] In addition, since the entire device is half submerged in water when working, and its top is not submerged in water, the waterproof level of some structures can be greatly reduced, saving costs.
