Description

Technical Field

[0001] The utility model relates to the technical field of sludge dewatering machines, in particular to a corrosion-resistant spiral stacking sludge dewatering machine. Background Art

[0002] Since the sludge is still in a liquid flow state and has a large volume after concentration or digestion, it cannot be transported and disposed of. In order to further reduce the moisture content and make the sludge moisture content as low as possible, the sludge must be dehydrated to reduce the sludge volume and facilitate transportation. The sludge dewatering machine is a continuously running sludge treatment equipment. It is popular among the public because of its low moisture content in the sludge, stable operation, low energy consumption, relatively simple control and management, and easy maintenance.

[0003] When the existing sludge dewatering machine dehydrates the soil, since some of the soil contains a large amount of acidic substances, during dehydration, the acidic water is in full contact with the working area of ​​the sludge dewatering machine. The longer the contact time, the easier it is for the working area of ​​the sludge dewatering machine to be corroded, resulting in internal failure of the sludge dewatering machine. Therefore, it is very necessary to design a sludge dewatering machine that is corrosion-resistant and practical. Utility Model Content

The spiral propulsion rod 11 rotates to transport and dehydrate the soil, and the water source flows into the dehydration box 1 through the water filter hole. The pH detector 12 detects the water source in real time to determine whether the water inside the soil is acidic or alkaline.
