Description

Technical Field

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

[0002] Sludge is a solid sediment produced by the water and sewage treatment process. Due to the high moisture content of sludge (generally 98%), the moisture content is still greater than 80% after dehydration. In order to properly handle the generated sludge, it is generally necessary to dry the sludge through special drying equipment to prevent sludge from piling up and polluting the surrounding environment.

[0003] When drying sludge, the sludge to be treated is generally sent to a drying device for drying through a conveying mechanism. However, when the existing sludge is sent to a drying device for drying through a conveying mechanism, the sludge transported on the conveying mechanism has uneven thickness and high density, resulting in incomplete drying of the lowest layer of sludge, affecting the drying quality of the sludge. Secondly, when the sludge is put in, since the sludge contains a certain amount of water, the sludge forms lumps when it is put in, causing accumulation inside the feeding pipe, resulting in pipe blockage, affecting the normal feeding of the sludge. In view of the above problems, the inventor proposes a sludge drying device to solve the above problems. Summary of the invention
