Description

Technical Field

[0001] This utility model belongs to the field of sludge detection, and specifically relates to a multifunctional sludge concentration settling ratio and concentration detection device. Background Technology

[0002] In the field of wastewater treatment, accurately determining sludge concentration and settling ratio is crucial. Traditional detection methods have many limitations: manual measurement of settling ratio is time-consuming, labor-intensive, and highly subjective, while common concentration detection equipment has limited functionality. To improve detection efficiency and accuracy, achieve integrated detection, and meet the needs of refined control in wastewater treatment processes, there is an urgent need to develop a multifunctional sludge concentration and settling ratio detection device to overcome existing technological bottlenecks and optimize wastewater treatment processes.

[0003] Existing technologies have specifically developed several multifunctional sludge concentration settling ratio and concentration detection devices. For example, Chinese patent publication number "CN221883387U" discloses "an automatic sludge settling ratio detection device," which measures the settling ratio of sludge and water in sewage by using two adjacent photoelectric sensors. After 30 minutes of sedimentation, the measurement data is obtained. Secondly, when it is necessary to clean the sludge inside the glass container, the telescopic motor is controlled to move the cleaning block upward via the telescopic rod. This allows the cleaning block to contact the inside of the glass container, scraping off the sludge inside. The sludge is then discharged by opening the control valve on the drain pipe.

[0004] Although the cleaning block is moved upwards by controlling the telescopic motor to scrape away sludge inside the glass container through contact with the interior of the glass container, and the sludge is discharged by opening the control valve on the drain pipe, the cleaning block cannot rotate effectively during use. As a result, debris will remain on the inner wall of the glass container after prolonged use. If the debris is not scraped and cleaned effectively and in a timely manner, it will become stuck inside and cannot be effectively cleaned and scraped away. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a multifunctional sludge concentration settling ratio and concentration detection device to solve the problem of sludge detection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

Detailed Implementation

[0025] Example

An installation groove 10 is provided inside the housing 7. A drive motor 22 is fixedly installed at the bottom of the installation groove 10. A rotating seat 16 is fixedly installed on the output shaft of the drive motor 22. A cylinder 15 is fixedly installed at the end of the rotating seat 16 away from the output shaft of the drive motor 22. An upper partition 9 is integrally formed at the upper end of the installation groove 10. A leak-proof sealing block 12 is fixedly installed at the upper end of the upper partition 9. A rotating plate 20 is fixedly installed through the output shaft of the cylinder 15, passing through the upper partition 9 and the leak-proof sealing block 12. Multiple inclined scraping pads 23 are provided on the outer ring of the rotating plate 20. The rotating plate 20 rotates inside the leak-proof sealing block 12. An inlet pipe 2 is fixedly connected to the upper end of the housing 7. A vertical flow labyrinth 4 is fixedly installed at the end of the inlet pipe 2 away from the housing 7. A drain pipe 6 is fixedly installed on one side of the housing 7. Multiple photoelectric sensors 25 are fixedly installed on both sides of the leak-proof sealing block 12 inside the housing 7.

[0027] refer to Figures 2 to 4 A lower partition 19 is integrally formed above the drive motor 22 and is located below the mounting groove 10. The output shaft of the drive motor 22 passes through the lower partition 19 and is fixedly connected to the rotating seat 16. A connecting block 18 is integrally formed inside the rotating seat 16 near the output shaft of the drive motor 22. The output shaft of the drive motor 22 is fixedly connected to the rotating seat 16 through the connecting block 18. A limiting seat 21 is fixedly installed on the upper end of the lower partition 19. A limiting groove 24 is opened inside the limiting seat 21. A limiting ring 17 is fixedly installed on the end of the rotating seat 16 near the lower partition 19. The limiting ring 17 is rotatably installed inside the limiting seat 21 through the limiting groove 24. When the limiting ring 17 rotates inside the limiting groove 24, it can effectively improve the stability of the drive motor 22 driving the cylinder 15 to rotate.

[0028] refer to Figure 4 A sealing ring 11 is fixedly installed at the center of the upper partition 9. The output shaft of the cylinder 15 passes through the sealing ring 11 and extends into the interior of the leak-proof sealing block 12. The leak-proof sealing block 12 has a circular groove 13 inside. An isolation pad 14 is fixedly installed at the bottom of the circular groove 13. The rotating plate 20 rotates inside the circular groove 13. The output shaft of the cylinder 15 passes through the isolation pad 14 and is fixedly connected to the rotating plate 20, which can improve the sealing effect of the circular groove 13 and ensure the quality of the test.

[0029] refer to Figures 1 to 4An inlet control valve 1 is fixedly installed on the upper end of the outer ring of the inlet pipe 2. A flow regulating valve 3 is fixedly installed on the side of the upper outer ring of the inlet pipe 2 away from the inlet control valve 1. A drain control valve 5 is fixedly installed on the upper outer ring of the drain pipe 6. The operator puts the sludge mixture to be tested into the device through the inlet pipe 2. The inlet control valve 1 installed on the upper end of the outer ring of the inlet pipe 2 can initially control the flow of liquid, ensuring that the liquid is only opened when the device is ready to receive samples. The flow regulating valve 3 on the side of the upper outer ring of the inlet pipe 2 away from the inlet control valve 1 can precisely regulate the flow rate of the liquid, which can avoid excessive water impact inside the device due to excessive liquid inflow, affecting subsequent testing, and also prevent excessively slow liquid inflow. After cleaning, the drain control valve 5 is opened, and the scraped sludge and the remaining liquid in the tank 7 are discharged from the device through the drain pipe 6. During the drainage process, the lower partition 19 separates the drive motor 22 from the drainage area, avoiding the corrosion of precision components such as the drive motor 22 by sewage, and extending the service life of the equipment.

[0030] refer to Figure 5 Inside the housing 7, there are mounting slots 26 on both sides of the leak-proof sealing block 12. Multiple photoelectric sensors 25 are fixedly installed inside the housing 7 on both sides through the mounting slots 26. An observation window 8 is provided at the upper end of one side of the housing 7. Multiple photoelectric sensors 25 are fixedly installed inside the housing 7 on both sides of the leak-proof sealing block 12. During the sludge settling process, the photoelectric sensors 25 use optical principles to monitor the changes in the mud-water interface in real time. While completing the settling ratio detection, they can also detect the sludge concentration.

[0031] Operating principle and advantages: When testing is required, the sludge mixture to be tested is introduced into the device through the inlet pipe 2. The inlet control valve 1 installed at the upper end of the outer ring of the inlet pipe 2 can initially control the flow of liquid, ensuring that the inlet is only opened when the device is ready to receive samples. The flow regulating valve 3 on the outer ring of the upper end of the inlet pipe 2, away from the inlet control valve 1, can precisely regulate the flow rate of the liquid. This avoids excessive water flow impact inside the device due to excessively fast inlet flow, which would affect subsequent testing, and also prevents excessively slow inlet flow, which would waste testing time. A vertical flow labyrinth 4 is fixedly installed at the end of the inlet pipe 2 away from the housing 7, which is used for inlet flow... Playing a crucial role in the process, the flow velocity of the sludge mixture is further homogenized as it flows through the labyrinth, which is beneficial to the accuracy of subsequent sedimentation and concentration detection. After the sludge mixture enters the tank 7 through the inlet pipe 2, the space enclosed by the leak-proof sealing block 12 located above the mounting groove 10 becomes the sedimentation area. The leak-proof sealing block 12 has a circular groove 13 inside, providing a relatively closed and stable environment for sludge sedimentation. Multiple photoelectric sensors 25 are fixedly installed on both sides of the leak-proof sealing block 12 inside the tank 7. During the sludge sedimentation process, the photoelectric sensors 25 use optical principles to monitor the changes in the mud-water interface in real time. The device can perform sludge concentration testing while simultaneously testing the settling ratio. After each test, the internal components of the device need to be cleaned to ensure the accuracy of the next test. At this time, the drive motor 22 starts, and its output shaft drives the rotating seat 16 to rotate. The rotating seat 16 then drives the cylinder 15 fixed at one end to rotate. The output shaft of the cylinder 15 passes through the upper partition 9 and the leak-proof sealing block 12, causing the rotating plate 20 fixed at the end of the output shaft of the cylinder 15 to rotate in the circular groove 13 inside the leak-proof sealing block 12. During rotation, the multiple inclined scraping pads 23 on the outer ring of the rotating plate 20 can scrape the circular groove. The inner wall of the tank 13 is thoroughly scraped to remove residual sludge adhering to the tank wall. The slanted design allows the scraper pad to generate a downward force when rotating, which helps push the scraped sludge to the bottom for easy subsequent discharge. The drain pipe 6 is located on one side of the tank 7, and a drain control valve 5 is fixedly installed on its upper outer ring. After cleaning, the drain control valve 5 is opened, and the scraped sludge and the remaining liquid in the tank 7 are discharged through the drain pipe 6. During the discharge process, the lower partition 19 separates the drive motor 22 from the discharge area, preventing sewage from corroding the drive motor 22 and other precision components, and extending the service life of the equipment.
