Description

Technical Field

[0001] The utility model relates to the field of environmental protection engineering, and more specifically, to a sludge dewatering device for environmental protection engineering. Background Art

[0002] Environmental protection projects refer to projects specifically designed for environmental protection. The contents of environmental protection projects mainly include air pollution prevention and control projects, water pollution prevention and control projects, solid waste treatment and utilization projects, and noise control projects. Among them, sludge dewatering devices are indispensable devices in water pollution prevention and control projects. Generally, granulation dewatering method is used for sludge dewatering. However, in the existing sludge dewatering devices, during the separation process of sludge balls and water, there is a situation where the sludge balls block the drainage holes, resulting in untimely separation of sludge balls and water, thus affecting the sludge dewatering efficiency.

[0003] Chinese patent application number: CN202221187558.1, provides a sludge dewatering device for environmental protection engineering. This solution first enters the granulation chamber after adding a high molecular weight coagulant into the sludge. Under the action of the sludge's own gravity, it flocculates and compresses, and forms sludge balls in layers. Then the sludge balls and water enter the dewatering chamber, which is used to complete the separation of sludge balls and water.

[0004] However, relying on the sludge's own gravity to flocculate and form sludge balls is slow, time-consuming, and inefficient, which is not conducive to high-intensity sludge dewatering operations. Therefore, a sludge dewatering device for environmental protection engineering is proposed to address the above problems. Utility Model Content
