[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a reagent dispensing device. Background Technology

[0002] Wastewater treatment chemical dosing systems are automated devices used to add chemical agents to wastewater, primarily for adjusting water quality, removing pollutants, or improving treatment effectiveness. They consist of a chemical storage system, pumps, a mixing system, and a control system, enabling precise control of the agent dosage to ensure efficient and stable treatment. These devices are widely used in industrial wastewater and municipal sewage treatment, and can treat suspended solids, heavy metals, phosphorus, nitrogen, and other pollutants, while also adjusting pH levels or inhibiting bacterial growth.

[0003] However, existing chemical dosing devices have the following drawbacks: Firstly, current devices are generally monolithic structures, requiring installation on top of the wastewater tank. Adding chemicals to the tank necessitates manual climbing to the top, which is inconvenient. Secondly, the dosing range is limited to the vicinity of the chemical discharge outlet, restricting the application area and hindering rapid and thorough mixing of chemicals and wastewater. Therefore, further improvements are needed. To address this, we propose a new chemical dosing device. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a drug dispensing device is disclosed, comprising a mounting plate 1 and a drug tank 2. A rotary spraying assembly 3 is mounted on the bottom of the mounting plate 1, and a geared motor 4 for driving the rotary spraying assembly 3 to rotate is mounted on the upper surface of the mounting plate 1. A pump body 6 is mounted on the outer wall of the drug tank 2, and the discharge port of the pump body 6 is connected to the rotary spraying assembly 3. An air pump 7 is mounted on the top of the drug tank 2 and is connected to the rotary spraying assembly 3. A stirring assembly is mounted in the middle of the drug tank 2, and a drug addition port 11 is provided on the top wall of the drug tank 2.

[0023] In this embodiment, an electrical control cabinet is also installed above the medicine box 2. The electrical control cabinet contains a PLC controller, specifically a Siemens SIMATIC KP1200 series (HMI+PLC integrated machine) KP1212 Basic PN controller with screen. This controller controls the operation of the geared motor 4, the pump body 6, and the air pump 7.

The inlet of the pump body 6 is connected to the inside of the medicine tank 2 through a pipe, and the outlet of the pump body 6 is fixedly connected to the inlet pipe 33 through a hose.

[0025] After the pump body 6 is started, the pump body 6 draws out the medicine in the medicine tank 2, and then sends it into the inlet pipe 33 through the pipeline, and then into the bottom of the U-shaped tube 31 through the inlet pipe 33.

[0026] An L-shaped connecting rod 5 is fixedly connected between the outer wall of the inlet pipe 33 and the lower surface of the mounting plate 1.

[0027] After being connected by the connecting rod 5, the liquid inlet pipe 33 can be kept stationary.

[0028] The end of the U-shaped tube 31 away from the first tube sleeve 32 is bent upward and fixedly connected to the second tube sleeve 34. The second tube sleeve 34 is rotatably connected to the air inlet pipe 35 through a sealed bearing.
