Description

Technical Field

[0001] The utility model relates to a novel submersible agitator installation device, which belongs to the technical field of sewage treatment equipment. Background Art

[0002] Submersible agitators play a crucial role in the production process of sewage treatment plants. Their primary function is to prevent sludge sedimentation and maintain sludge activity in the biological tank, thereby ensuring the proper functioning of the biochemical system. While the current method of fixing the guide rod to the tank bottom is widely used, it does present some issues, such as loosening of the guide rod fixing bolts and breakage. These issues are not only difficult to detect but also complex to address, requiring significant engineering effort. Furthermore, when the agitator's guide rod is damaged, it often requires drainage and maintenance. However, due to the need for continuous production at water plants, drainage and maintenance often fall short of actual production requirements, resulting in equipment failure to be repaired and put back into operation in a timely manner. This not only impacts the proper functioning of the biochemical system but can also result in significant economic losses. Furthermore, system drainage and maintenance can negatively impact sludge activity in the biological tank. During drainage and maintenance, environmental conditions in the biological tank may change, leading to reduced sludge activity and even the death of activated sludge. This not only increases the difficulty and cost of sludge treatment but also impacts the stability and efficiency of the entire sewage treatment system. Utility Model Content
