[0002] Sludge dewatering is an important step in the sewage treatment process. Its purpose is to reduce the moisture content in the sludge and reduce its volume to facilitate subsequent transportation, disposal or final treatment (such as landfill, incineration, land use, etc.).

[0003] However, in the prior art, when the conventional sludge dewatering and unloading device is unloading, there will still be excess water mixed with the sludge. Therefore, when the sludge is collected and processed in a centralized manner, sewage is easily leaked, thereby causing pollution to the surrounding area. Cleaning is also relatively time-consuming and labor-intensive. In addition, the sludge is easy to adhere to the filter dewatering plate. If it is not cleaned for a long time, it will affect the dewatering effect, thereby reducing the separation of sludge and water. Utility Model Content
