Description

Technical Field

[0001] The utility model relates to a dewatering device, in particular to a multi-layer integrated belt-type deep dewatering device, belonging to the technical field of sludge dewatering. Background Art

[0002] Sludge dehydration refers to the process of removing part of the moisture from sludge containing a large amount of water and reducing its humidity, thereby reducing its volume and weight for subsequent processing and disposal. Existing sludge is usually dehydrated using a high-pressure belt machine, which can evenly distribute the pre-treated sludge on the filter belt, and then apply high pressure to the filter belt to squeeze the water out of the sludge to achieve the dehydration effect.

[0003] While the existing sludge dewatering equipment can perform extrusion dehydration treatment on the sludge during use, the dehydration effect of the sludge is not very good, resulting in a high water content in the sludge. Multiple dehydration operations are required to obtain sludge with a low water content, which is troublesome to operate and reduces the practicality of the equipment. Utility Model Content
