Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration, in particular to sludge dehydration equipment. Background Art

[0002] Sludge dewatering is a sludge treatment method that removes water from flowing primary, concentrated or digested sludge and converts it into semi-solid or solid mud blocks. After dewatering, the moisture content of the sludge can be reduced to 55% to 80%, depending on the properties of the sludge and sediment and the efficiency of the dewatering equipment. Further dehydration of sludge is called sludge drying, and the moisture content of dried sludge is less than 10%. The main methods of dehydration are natural drying, mechanical dehydration and granulation. Natural drying and mechanical dehydration are suitable for sewage sludge. Granulation is suitable for coagulated and precipitated sludge.

[0003] At present, the sludge dewatering equipment using mechanical dewatering method is provided with a detachable dewatering barrel inside. After dewatering is completed, the dewatering barrel and the inside of the equipment can be cleaned by disassembling the dewatering barrel. However, since the dewatering barrel inside the sludge dewatering equipment is troublesome to disassemble and assemble, it is inconvenient for users to clean the sludge dewatering equipment.
