Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, specifically to an intelligent dosing control device for wastewater treatment plants. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering.

[0003] In wastewater treatment, the wastewater is typically first filtered through sedimentation, and then the coarsely filtered wastewater is fed into a wastewater treatment tank. To improve the quality of subsequent wastewater treatment, intelligent dosing control devices are usually used to improve the quality of the effluent, such as chlorine dioxide generators. When preparing chlorine dioxide, solutions such as sodium chlorate and hydrochloric acid are required, which are then mixed with water or other solutions.

[0004] Existing intelligent dosing devices typically use a motor-driven stirring rod to mix the raw materials, water, and other solvents in the dosing tank to improve the mixing effect of the chemicals, thereby increasing the mixing speed. However, after stirring, the stirring rod will have a lot of chemical residues, requiring cleaning to extend the service life of the components. Most stirring rods and stirring shafts are fixedly installed, making it inconvenient to clean the stirring rod. Moreover, when the stirring rod is damaged and needs to be replaced, the entire stirring shaft and stirring rod must be replaced together, making maintenance inconvenient. To solve the above problems, an intelligent dosing control device for wastewater treatment plants is proposed to address these issues. Utility Model Content

[0005] In view of this, the present invention provides an intelligent dosing control device for sewage treatment plants. The present invention separates the slot from the insert by pulling out the bolt, and then drives the connecting plate to rise and fall by the electric lifting rod, thereby adjusting the height of the tank cover and the dosing tank. After the dosing tank is separated from the tank cover, the external threaded column is separated from the positioning ring by rotating the stirring rod or the hollow ball, so that the stirring rod can be taken out for cleaning, or the height of the electric lifting rod can be gradually increased and the stirring rod and the hollow ball can be rinsed with a high-pressure water gun. Individual stirring rods can also be replaced, thus facilitating the disassembly and cleaning of the stirring rods in the dosing tank.

[0006] To solve the above-mentioned technical problems, this utility model provides an intelligent dosing control device for sewage treatment plants, including a dosing tank mounted on a support frame.
