Description

Technical Field

[0001] The utility model relates to the technical field, in particular to sludge processing equipment for water conservancy projects. Background Art

[0002] The sludge produced in sewage treatment can be roughly divided into three categories: biochemical sludge, physicochemical sludge, and physicochemical-biochemical mixed sludge. At present, most sludge treatments need to be used in conjunction with sludge dewatering equipment. The centrifugal sludge dewatering machine is composed of a transfer and a screw conveyor with a hollow shaft. The sludge is sent into the drum by the hollow shaft and is immediately thrown into the drum cavity under the centrifugal force generated by high-speed rotation. Due to the different specific gravities, solid-liquid separation is formed. The sludge is pushed by the screw conveyor and transported to the conical end of the drum and continuously discharged from the outlet.

[0003] The moisture content of the sludge after dehydration by the sludge centrifugal dehydrator is between 70% and 80%, which is still relatively high and inconvenient for subsequent transportation and treatment. Therefore, in order to further reduce the moisture content of the sludge, the sludge that has been initially centrifugally dehydrated is often dried and dehydrated for the second time. In the secondary drying, the dryer often needs to be equipped with a rotating motor to turn the sludge, so the cost is relatively high. Before drying, the staff needs to load the centrifugally dehydrated sludge into a transfer vehicle and then transport the sludge to the drying site, which is also time-consuming and labor-intensive.
