Description

Technical Field

[0001] This utility model relates to the field of water quality detection and treatment technology, specifically to an automatic dosing device for water quality sensors. Background Technology

[0002] Water quality sensors are key devices for monitoring water quality, capable of real-time detection of multiple critical indicators. They can accurately measure parameters such as dissolved oxygen, pH, conductivity, turbidity, and heavy metal ion concentration, providing data support for drinking water safety, industrial wastewater treatment, aquaculture, and river and lake ecological monitoring. Their working principles are diverse, including electrochemical, optical, or ion-selective electrode methods, ensuring high sensitivity and stability in various scenarios. Modern water quality sensors often possess intelligent functions, supporting wireless transmission and remote monitoring. Combined with data analysis systems, they can achieve pollution early warning and trend prediction, featuring small size, fast response, and strong anti-interference capabilities.

[0003] Utility model patent CN222524222U discloses an automatic dosing device for water quality monitoring, including a medicine tank, a discharge port, and a feeding port. The bottom of the medicine tank is equipped with a dispersion component to assist in drug diffusion. The dispersion component includes a feeding box, a drive platform, a motor, a first pulley, a connecting belt, a second pulley, a rotating shaft, and a dispensing plate. This utility model, by incorporating a dispensing plate located below the discharge port, allows the motor to drive the first pulley, which in turn drives the connecting belt. When the connecting belt further drives the second pulley, it in turn drives the dispensing plate on the outside of the rotating shaft. The rotating dispensing plate contacts the drug falling from the discharge port, and with the aid of the dispensing plate, the drug is dissipated outwards along the dispersion channel, increasing the drug projection range and enhancing the overall drug projection range of the dosing device.

[0004] However, in common automatic dosing devices, the water quality sensor used to detect water quality needs to be cleaned every day, which consumes a lot of time. Therefore, an automatic dosing device with a water quality sensor is proposed to solve the problems mentioned above. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4This embodiment of an automatic dosing device for a water quality sensor includes a vertical pipe 1, a bend 2, and a horizontal pipe 3. A water quality sensor 4 is installed inside the vertical pipe 1. A mounting plate 5 is fixedly installed on the top of the horizontal pipe 3, and a dosing pump 6 is fixedly installed on one side of the mounting plate 5. A dosing pipe 7 is fixedly installed at the output end of the dosing pump 6, and the bottom of the dosing pipe 7 is connected to the horizontal pipe 3. The vertical pipe 1, the bend 2, and the horizontal pipe 3 are connected in sequence.

[0025] The water quality sensor 4 includes a mounting tube 41 fixedly installed on the surface of a vertical pipe 1. An inner sensor tube 42 passes through the mounting tube 41. A detection head 43 is fixedly installed at one end of the inner sensor tube 42. An inner sleeve 44 is fixedly installed on the inner wall of the vertical pipe 1. A mounting rod 45 passes through the top of the inner sleeve 44. An ultrasonic vibrator 46 is fixedly installed at the bottom of the mounting rod 45. A limiting end plate 47 is fixedly installed at the top of the mounting rod 45. A mounting spring 48 is fixedly installed at the bottom of the limiting end plate 47. The bottom end of the mounting spring 48 is fixedly connected to the top of the inner sleeve 44. The mounting spring 48 pulls down the limiting end plate 47, causing the ultrasonic vibrator 46 to adhere to the surface of the inner sensor tube 42.

[0026] Specifically, the sensor inner tube 42 is inserted into the installation tube 41, so that the detection head 43 is placed inside the vertical tube 1 to detect the water quality. When it is necessary to clean the detection head 43, the ultrasonic vibrator 46 is activated, which drives the sensor inner tube 42 to vibrate, which in turn drives the detection head 43 to vibrate, shaking off the impurities on the surface of the detection head 43 and washing them away with the water flow.

[0027] Please see Figure 1 and Figure 2 In this embodiment, a dosing tank 8 is fixedly installed at the input end of the dosing pump 6, a dosing valve 9 is fixedly installed on the surface of the output pipe of the dosing tank 8, a flow meter 10 is fixedly installed inside the dosing pipe 7, and a controller 11 is fixedly installed on one side of the mounting plate 5. The detection head 43 detects the water quality and transmits the water quality data to the controller 11. The calculation program in the controller 11 calculates the amount of medicine to be added, opens the dosing valve 9, and the flow meter 10 detects the amount of medicine to be added. When the required amount of medicine is reached, the controller 11 controls the dosing valve 9 to close, completing the precise dosing.

[0028] Among them, an installation block 12 is fixedly installed on one side of the bend 2, a mixing shaft 13 is passed through one side of the installation block 12, and a mixing screw rod 14 is fixedly installed at one end of the mixing shaft 13. The mixing screw rod 14 is located below the dosing pipe 7.

[0029] Secondly, a mixing motor 15 is fixedly installed on one side of the mounting block 12, and the output shaft of the mixing motor 15 is fixedly connected to one end of the mixing shaft 13. When adding chemicals, the mixing motor 15 drives the mixing shaft 13 to vibrate, which in turn drives the mixing screw 14 to vibrate, mixing the water and chemicals in the horizontal pipe 3 and increasing the mixing efficiency.

[0030] Please see Figure 1 In this embodiment, the top flange of the dosing tank 8 is connected to a top cover 16, and an anti-condensation shaft 17 is rotatably installed at the bottom of the top cover 16. Anti-condensation blades 18 are fixedly installed on the surface of the anti-condensation shaft 17.

[0031] An anti-condensation motor 19 is fixedly installed on the top of the top cover 16. The output shaft of the anti-condensation motor 19 is fixedly connected to the top end of the anti-condensation shaft 17. A feed pipe 20 is fixedly installed on the top of the top cover 16. The anti-condensation motor 19 drives the anti-condensation shaft 17 to rotate, which in turn drives the anti-condensation blades 18 to rotate, stirring the chemicals in the dosing tank 8 and preventing the chemicals from condensing.

[0032] Please see Figure 1 and Figure 3 In this embodiment, a threaded connector 21 is fixedly installed at one end of the sensor inner tube 42. The threaded connector 21 is threadedly connected to the mounting tube 41. A mounting end plate 22 is fixedly installed on one side of the threaded connector 21, and a mounting ring 23 is fixedly installed on one side of the mounting end plate 22. A sealing ring 24 is fitted onto the surface of the sensor inner tube 42. The sealing ring 24 seals the sensor inner tube 42 to prevent leakage.

[0033] Please see Figure 2 In this embodiment, an observation window 25 is fixedly installed on one side of the dosing tank 8, and a liquid level scale line 26 adapted to the observation window 25 is engraved on one side of the dosing tank 8.

[0034] It should be noted that the sensor inner tube 42 and the detection head 43 in the water quality sensor 4 are common sensor structures used for water quality detection and are existing technologies. Their specific structures will not be described in detail in this article.

[0035] The working principle of the above embodiment is as follows: The sensor inner tube 42 is inserted into the installation tube 41, so that the detection head 43 is placed inside the vertical tube 1 to detect the water quality. When the detection head 43 needs to be cleaned, the ultrasonic vibrator 46 is started, which drives the sensor inner tube 42 to vibrate, which in turn drives the detection head 43 to vibrate, shaking off the impurities on the surface of the detection head 43 and washing them away with the water flow. The detection head 43 detects the water quality and transmits the water quality data to the controller 11. The calculation program in the controller 11 calculates the amount of chemical to be added, opens the chemical dosing valve 9, and the flow meter 10 detects the amount of chemical to be added. When the required amount of chemical is reached, the controller 11 controls the chemical dosing valve 9 to close.
