Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an activated carbon dosing device. Background Technology

[0002] In the field of wastewater treatment, the biological activated carbon method refers to adding powdered activated carbon to the return sludge of an aerobic system. Through the interaction between the powdered activated carbon (PAC) in the carbon-containing sludge and the microorganisms in the activated sludge, the removal efficiency of pollutants in wastewater is improved.

[0003] A search revealed that patent CN219334081U discloses a powdered activated carbon dosing device with good dust prevention effect. This device fixes the position of the dust collection box by installing it inside the mounting frame. Additionally, after the ash pump is started, it draws dust from the feeding hopper into the suction ring, and then into the dust collection box. The dust is filtered through filter plates A and B, and the drawn-in gas is discharged, thus achieving a dust prevention function and improving the safety of powdered activated carbon dosing. The filter plates A and B allow for separate filtration and collection of dust.

[0004] Although the above solution can remove the dust from the feeding hopper by using a dust pump to achieve a certain dust prevention effect, the device does not have dust prevention capabilities at the feeding hopper. When the bagged powdered activated carbon is broken and poured into the feeding hopper, a lot of dust will still be generated, which needs to be improved. Utility Model Content

[0020] Please see Figures 1-3 In this embodiment of the present invention, an activated carbon dosing device includes a feeding box 1 fixedly installed on a support 2. A feeding port 3 is provided on the outer wall of one end of the feeding box 1. The bottom of the feeding box 1 is tapered and has a discharge port 4. A guide pipe 5 is fixedly connected to the discharge port 4. The discharge end of the guide pipe 5 extends into the wastewater to be treated. A slider 12 is connected to the feeding box 1 through a linear drive mechanism. A plurality of hooks 13 are fixedly installed on the bottom of the slider 12. A rotating shaft 7 is rotatably installed in the feeding box 1. A blade 8 is fixedly sleeved on the outer wall of the rotating shaft 7. A bag breaking mechanism is installed in the feeding box 1. A fan mechanism is installed on the top of the feeding box 1.

[0021] This utility model, by adopting the above-mentioned scheme, fixes the feeding box 1 to one side of the sewage treatment tank through the bracket 2, and extends the bottom end of the guide pipe 5 into the sewage. Then, the woven bag containing powdered activated carbon is placed in the feeding port 3 and hooked on the hook 13. Then, the linear drive mechanism drives the slider 12 to move, so as to move the woven bag to the bag breaking mechanism, which can break the woven bag and spill out the powdered activated carbon, so that the powdered activated carbon is discharged into the sewage through the guide pipe 5. Through the setting of the wind-facing mechanism, the air in the feeding box 1 can be drawn out to create a negative pressure in the feeding box 1, so that the outside air enters the feeding box 1 through the feeding port 3, effectively preventing the dust in the feeding box 1 from drifting outward. The effect is good. After the feeding is completed, the linear drive mechanism is activated to move the slider 12 back to the feeding port 3, so that the woven bag can be removed from the hook 13.

[0022] Specific combination Figure 1 and Figure 2 In one embodiment of the present invention, the bag breaking mechanism includes a rotating shaft 7 rotatably installed in the feeding box 1.
