[0020] like Figure 1 , Figure 2 As shown, a preferred embodiment of the present invention provides an activated carbon precise metering and dosing device, including a frame 5, a storage bin 1, a metering tank 2, a conveying tank 3 and a control cabinet 4 installed on the frame 5, wherein the storage bin 1, the metering tank 2 and the conveying tank 3 are arranged sequentially from top to bottom.

[0021] Storage chamber 1 is used to store activated carbon. Its capacity is designed to meet water treatment needs for a certain period of time. Storage chamber 1 also has good sealing performance to prevent the activated carbon from becoming damp and affecting its adsorption effect. The bottom of storage chamber 1 is funnel-shaped and positioned directly above metering tank 2. A pneumatic solenoid valve 11 is installed at the bottom of storage chamber 1. Control cabinet 4 is electrically connected to an external power supply and contains a PLC controller. The PLC controller automates the addition of activated carbon. The pneumatic solenoid valve 11 is electrically connected to the PLC controller, which controls its opening and closing. When the pneumatic solenoid valve 11 is open, the activated carbon in storage chamber 1 falls into metering tank 2.

[0022] The metering tank 2 is positioned directly above the conveying tank 3 and is used to weigh the activated carbon and monitor its weight in real time. Multiple weighing sensors 21 are installed at the bottom of the metering tank 2 to weigh the activated carbon. The weighing sensors 21 are communicatively connected to the PLC controller, sending measurement signals to the PLC. The selection of the weighing sensors 21 considers factors such as range, accuracy, and stability; high-precision weighing sensors 21 are used in the metering tank 2 to ensure accurate measurement of the activated carbon weight. The installation position and method of the weighing sensors 21 affect the measurement accuracy and require proper design and installation. The weighing sensors 21 are calibrated periodically to ensure the accuracy of the measurement data.

[0023] A first pneumatic door 25 is provided at the bottom opening of the metering tank 2, and a second pneumatic door 30 is provided at the top opening of the conveying tank 3. By opening the first pneumatic door 25 and the second pneumatic door 30, activated carbon weighed to the preset weight in the metering tank 2 falls into the conveying tank 3. The first pneumatic door 25 and the second pneumatic door 30 are electrically connected to a PLC controller via valves, and the PLC controller controls the opening and closing of the first pneumatic door 25 and the second pneumatic door 30.

[0024] A circular rotating guide disk 22 is provided inside the measuring tank 2. The rotating guide disk 22 is rotatably connected to the measuring tank 2 via a rotating shaft 24. The measuring tank 2 has a cylindrical body, and the outer edge of the rotating guide disk 22 abuts against the inner wall of the measuring tank 2. A drive mechanism is provided on the outside of the measuring tank, and the drive mechanism is connected to the rotating shaft 24. Specifically, the drive mechanism is a drive motor 23 installed on the outer wall of the measuring tank 2. The drive shaft of the drive motor 23 is connected to the rotating shaft 24. The drive motor 23 drives the rotating shaft 24 to rotate, thereby driving the rotating guide disk 22 to rotate. The rotating guide disk 22 flips and tilts at a certain angle, causing the activated carbon on the rotating guide disk 22 to slowly slide down to the bottom of the measuring tank 2, facilitating accurate measurement of the weight of the activated carbon. The drive motor 23 is electrically connected to a PLC controller, which controls the drive motor 23 to drive the rotating shaft 24 to rotate.

[0025] The conveying tank 3 is used to transport and add activated carbon to wastewater for purification. The bottom of the conveying tank 3 has a conical structure, wider at the top and narrower at the bottom, and is connected to a conveying pipe 32. One end of the conveying pipe 32 is connected to the discharge end at the bottom of the conveying tank 3, and the other end is positioned directly above the wastewater tank 6. The conveying tank 3 must have good sealing and wear resistance. Multiple compressed air solenoid valves 31 are installed on the inclined surface of the conical structure at the bottom of the conveying tank 3. These valves are connected to a compressed air source via air pipes and are electrically connected to a PLC controller. The PLC controller controls the opening and closing of the compressed air solenoid valves 31. When the compressed air solenoid valve 31 is open, compressed air enters the conveying tank 3, providing power. Under the action of the compressed air, the activated carbon in the conveying tank 3 is transported to the wastewater tank 6 through the conveying pipe 32.

[0026] Preferably, the second pneumatic solenoid valve 33 is located at the connection between the conveying tank 3 and the conveying pipeline 32. The second pneumatic solenoid valve 33 is electrically connected to the PLC controller. The PLC controller controls the opening and closing of the second pneumatic solenoid valve 33. When the second pneumatic solenoid valve 33 is open, the activated carbon in the conveying tank 3 can slide down the conveying pipeline 32 to the sewage tank 6 for sewage purification.

[0027] In use, the PLC controller sets the dosage of activated carbon according to the water quality. After the weight is set, the pneumatic solenoid valve 11 opens, and the activated carbon in the storage chamber 1 falls into the metering tank 2. Multiple weighing sensors 21 are installed at the bottom of the metering tank 2 to weigh the activated carbon. The rotating guide plate 22 inside the metering tank 2 is driven by the drive motor 23 to rotate, causing the activated carbon on the rotating guide plate 22 to slowly slide down to the bottom of the metering tank 2, allowing for fine-tuning of the activated carbon weighing. After the activated carbon slowly accumulates to the set weight, the weighing sensor 21 sends a signal to the PLC controller. The PLC controller then controls the opening of the first pneumatic door 25 and the second pneumatic door 30, allowing the activated carbon in the metering tank 2 to fall into the conveying tank 3. Next, the PLC controller controls the opening of the compressed air solenoid valve 31 at the bottom of the conveying tank 3, allowing compressed air to enter the tank. This compressed air provides power, and the activated carbon in the conveying tank 3 is transported to the sewage tank 6 through the conveying pipe 32 under the action of the compressed air, achieving quantitative addition of activated carbon. The entire process is automated, ensuring precise addition of activated carbon.

[0028] Compared with the prior art, the activated carbon precise metering and dosing device of this utility model stores activated carbon in a storage chamber 1, and a metering tank 2 is equipped with multiple weighing sensors 21 at the bottom. The weighing sensors 21 weigh the activated carbon in the metering tank 2. After the activated carbon in the metering tank 2 reaches the set weight, the activated carbon in the metering tank 2 falls into the conveying tank 3. The compressed air solenoid valve 31 at the bottom of the conveying tank 3 is opened, and compressed air enters the conveying tank 3. The compressed air provides power, and the activated carbon in the conveying tank 3 is transported to the sewage tank 6 through the conveying pipe 32 under the action of the compressed air. This realizes the automated control of quantitative dosing of activated carbon, avoids the situation of inaccurate dosing of activated carbon, stabilizes the water treatment effect, and reduces the waste of activated carbon.

[0029] Any descriptions not covered in the above specific embodiments of this utility model belong to the well-known technology in the field, and can be implemented by referring to the well-known technology.

[0030] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
