Technical Field

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

[0002] Sludge treatment is the process of reducing, stabilizing and harmlessly treating sludge. The higher the degree of sewage treatment, the more sludge residue will be produced and need to be treated. When treating sludge, it is often necessary to use a drying device to dehydrate the sludge in order to reduce the water content of the sludge, thereby facilitating subsequent treatment.

During the heating and drying process, since the water content of the sludge is generally high, it takes a long time to completely dry the sludge, resulting in low processing efficiency, which needs further improvement. Therefore, in order to solve the above problems, the present application proposes a sludge drying device. Utility Model Content

During this process, the operation of the double-shaft extension motor 11 will also drive the connecting moving rod 6 to move up and down reciprocally through the reciprocating driving assembly, and then can drive the suction piston 5 to move up and down reciprocally together. Under the combined action of the air extraction pipe, the air outlet pipe and the one-way valve 7, the air below the filter screen plate 2 can be extracted to generate negative pressure. At this time, with the combined cooperation of the filter screen plate 2 and the filter cloth 3, most of the water in the sludge can be sucked out under negative pressure, so that the time required to completely dry the sludge can be greatly reduced, and the drying efficiency of the device for sludge can be effectively improved, and the practicability is good.
