Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration, in particular to a dosing device in a desludge chamber. Background Art

[0002] In the desludging process, the dosing device plays a vital role. The dosing device is mainly used to add specific chemical agents to the desludging system to change the physical and chemical properties of the mud, thereby achieving the purpose of improving the desludging efficiency and optimizing the mud-water separation effect; the existing dosing device lacks the function of stirring the drugs, which easily causes agglomeration when the drugs are added, resulting in incomplete sludge dehydration.

[0003] A Chinese patent discloses a sludge dehydration and dosing stirring device (authorization announcement number CN220618738U). The patented technology uses the cooperation of a feeding pipe and a feeding hopper to facilitate the staff to add drugs and avoid drug spillage. The second drive motor can drive the stirring rod to rotate to stir the drugs to avoid agglomeration when the drugs are added. The first drive motor can drive the spiral blade and the stirring frame to rotate, and the spiral blade and the stirring frame are used to rotate to stir the sludge and the drugs, so that the sludge is quickly dehydrated and the thoroughness of the sludge dehydration is improved. The scraper can be used to scrape the inner wall of the dehydration tank;

[0004] However, it has certain disadvantages: it is impossible to clean the inner wall of the dosing tank, and there will be residual drugs on the inner wall of the dosing tank. These drugs will form dirt that is difficult to clean after a long time without cleaning, and these drugs will lose their efficacy after a long time, resulting in waste. Utility Model Content
