Description

Technical Field

[0002] Utilizing powdered materials to treat sludge is an effective method of sludge treatment. For example, lime powder can neutralize acidic substances in sludge through its alkaline properties, adjust the pH value of sludge, and thus improve the physicochemical properties of sludge, making it easier to handle and dispose of. These powders can not only promote the degradation and precipitation of organic matter in sludge, accelerate the solidification process of sludge, and reduce sludge volume, but also play a bactericidal and disinfecting role, effectively removing pathogens and odors from sludge.

[0003] When using powder to treat sludge, the powder may clump due to moisture during storage. Clumped powder is difficult to mix fully with sludge, thus affecting the reaction effect. To address this problem, a mixing device for sludge treatment is proposed. Utility Model Content

Finally, they separate from the bottom of the feeding pipe 103 and fall to the side of the extension rod 207.

[0034] Secondly, when the motor 202 starts, it also drives the ring rack 203 to rotate continuously. The ring rack pushes the meshing gears 206 on both sides. The gears 206 drive the lower extension rod 207 to rotate continuously, and then the stirring rod 208 stirs and mixes the sludge and the falling powder.
