The invention relates to a rapid sludge dewatering and drying device. The rapid sludge dewatering and drying device comprises an upper tank body, a lower tank body, a pressure monitoring device used for monitoring the pressure of an inner cavity of the upper tank body and a vacuum tank; the upper tank body is connected with a pressurizing device communicated with the inner cavity of the upper tank body, the upper tank body is further provided with a sludge inlet, a filtering layer is arranged in the lower tank body, and a first negative pressure pipe opening is formed in the lower tank body under the filtering layer; a second negative pressure pipe opening is formed in the vacuum tank, the first negative pressure pipe opening is communicated with the second negative pressure pipe opening through a negative pressure pipe, and the vacuum tank is connected with a vacuumizing device; a first water drainage opening is formed in the lower tank body and connected to a sewage collecting pool through a first water drainage pipe, and a second water drainage opening is formed in the vacuum tank and communicated to the sewage collecting pool through a second water drainage pipe. According to the scheme, the rapid sludge dewatering and drying device has the advantages that the sewage dewatering rate is high, the dewatering efficiency is higher, and filter residues are convenient to recycle.
Description
technical field [0001] The invention belongs to the field of water treatment sludge dehydration equipment, and in particular relates to a rapid dehydration and drying device for sludge. Background technique [0002] In the process of sewage treatment, some sewage contains a large number of larger particles and suspended solids that are difficult to settle, and some particles and suspended solids are difficult to biochemically degrade. At this time, the sewage is usually dehydrated. After dehydration, the formation The filter residue can be recycled as filler. [0003] For example, in the authorized announcement number CN204434447U, the Chinese invention patent titled "An Improved Vacuum Sludge Dewatering Device" discloses an improved sludge vacuum dewatering device, including closed sewage The buffer tank, the sewage buffer tank is connected with a dehydration pipe, a vacuum pipe and several connecting pipes for inserting into the sludge water, the other end of the vacuum p...
