Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an automatic dosing system for wastewater treatment. Background Technology

[0002] In the wastewater treatment process, chemicals need to be added frequently to the wastewater treatment tanks to improve the treatment effect and efficiency. Automatic dosing systems play a crucial role, automatically adding appropriate chemicals based on the wastewater quality to achieve the goal of purifying the wastewater.

[0003] Existing automatic dosing systems for wastewater treatment are inconvenient to mix chemicals evenly in the wastewater tank and to dispense chemicals evenly. They also make it difficult to mix chemicals evenly in the storage tank, which can easily lead to sedimentation and stratification, affecting the efficacy of the chemicals. Furthermore, it is not easy to monitor the remaining amount of chemicals in the storage tank, which means that the chemicals cannot be replenished in time when they are depleted. In addition, the motor and water pump continue to operate, consuming energy and wasting resources. Therefore, the device has certain shortcomings. Utility Model Content

[0031] The mixing assembly includes a support base 2, which is fixedly connected to the side of the sewage tank 1. A drive motor 3 is fixedly connected to the top of the support base 2 by bolts. The output end of the drive motor 3 passes through the side wall of the sewage tank 1 and is fixedly connected to a threaded rod 4. The output shaft of the drive motor 3 rotates inside the outer wall of the sewage tank 1. An electromagnetic brake is installed on the output shaft of the drive motor 3. A movable plate 5 is threadedly connected to the outer wall of the threaded rod 4. One side of the movable plate 5 slides on the inner wall of the sewage tank 1. A top plate 6 is fixedly connected to the other side of the movable plate 5. A stirring blade 7 is fixedly connected to the bottom of the top plate 6. Multiple sets of stirring blades 7 are provided. A water pump 15 is bolted to the outer wall of the medicine storage tank 8. An inlet pipe is connected to the inlet of the water pump 15 and extends into the medicine storage tank 8. A hose 16 is connected to the outlet of the water pump 15. One end of the hose 16 passes through the top plate 6 and is threadedly connected to a nozzle 19 for easy spraying of medicine.

[0032] The stirring assembly includes a stirring rod 9, one end of which is rotatably connected to the side wall of the storage tank 8. Another end of the stirring rod 9 passes through the storage tank 8 and is fixedly connected to a first pulley 10. One end of a threaded rod 4 passes through the sewage tank 1 and is fixedly connected to a connecting rod 11. One end of the connecting rod 11 is fixedly connected to a second pulley 12. A belt body 13 is installed on the outside of the second pulley 12 and the first pulley 10. A stirring plate 14 is fixedly connected to the outer wall of the stirring rod 9, and multiple sets of stirring plates 14 are provided. An alarm 17 and a controller 18 are both fixedly connected to the outside of the storage tank 8 by bolts. The liquid level... Sensor 20 is fixedly connected to the bottom of the medicine storage tank 8. The drive motor 3, water pump 15, alarm 17 and liquid level sensor 20 are all electrically connected to the controller 18. Support legs 26 are fixedly connected to the bottom of the sewage tank 1, and two sets of support legs 26 are symmetrically arranged. A drain outlet 21 is opened at the bottom of the sewage tank 1.

The top plate 6 is parallel to the bottom of the sewage tank 1 and can be used for uniform stirring.

[0033] Working principle: In the automatic dosing system for wastewater treatment, starting the drive motor 3 drives the threaded rod 4 to rotate, which in turn drives the moving plate 5 to reciprocate horizontally, thereby driving the top plate 6 to move horizontally and causing multiple sets of stirring blades 7 to reciprocate, facilitating more uniform mixing of wastewater and chemicals in the wastewater tank 1. Furthermore, after starting the water pump 15, the nozzle 19 moves with the moving plate 5 to spray, increasing the dosing area and aiding mixing. Simultaneously, starting the drive motor 3 and driving the threaded rod 4 to rotate also drives the connecting rod 11 to rotate. The connecting rod 11 drives the second pulley 12 to rotate, which in turn drives the belt body 13 to rotate. 3 drives the first pulley 10 to rotate, thereby causing the stirring rod 9 to drive the stirring plate 14 to rotate, which facilitates continuous stirring of the medicine in the medicine storage tank 8 and avoids long-term static sedimentation or stratification, which would affect the efficacy of the medicine. The drive motor 3, water pump 15, alarm 17 and liquid level sensor 20 are all electrically connected to the controller 18, so that the liquid level sensor 20 monitors the remaining medicine in the medicine storage tank 8. When it detects that it is about to run out, it sends a signal to the controller 18. The controller 18 controls the alarm 17 to sound an alarm to remind the staff to add medicine in time. At the same time, the controller 18 controls the drive motor 3 and water pump 15 to stop running, saving resources.
