Description

TECHNICAL FIELD

[0002] Sludge is solid precipitate produced in water and sewage treatment process, and in the treatment of sludge, drying equipment is needed to reduce the moisture content, so as to achieve the purpose of solid-liquid separation. Sludge drying, also known as sludge dewatering, is a process of removing most of the water content from sludge through filtration or evaporation. It generally refers to the use of self-evaporation facilities such as sludge drying fields (beds). After sludge is concentrated, physical methods are used to further reduce the moisture content of the sludge, making it easier to transport, store, use, or further process.

[0003] For example, patent No. CN216890592U discloses a sludge drying treatment equipment.

[0028] In the embodiment, a drainage interval is formed between the sludge drying filter cylinder 2 and the water collecting cylinder 3, and a drain pipe 17 is fixedly penetrated through the outer surface of the water collecting cylinder 3 and is in communication with the drainage interval.

[0030] In the embodiment, a pair of sludge discharging baffles 4 are movably connected in the base 1, and the pair of sludge discharging baffles 4 are used to control the discharge of the sludge in the sludge drying filter cylinder 2.

[0031] In the present application, the sludge drying filter cylinder 2 is provided with openings at both ends, and the sludge discharging baffles 4 can flexibly block the bottom of the sludge drying filter cylinder 2, so as to control the discharge of the dewatered sludge.

[0032] A discharging groove 12 is formed in the side of the base 1, a guide groove 13 is formed in the top of the base 1, the discharging groove 12 is in communication with the guide groove 13, and the sludge drying filter cylinder 2 fixedly connected to the base 1 is in communication with the guide groove 13.

[0036] In this embodiment, the sludge drying filter cartridge 2 and the water collecting cylinder 3 are fixedly penetrated with a feeding cover 5, the feeding cover 5 is provided with a sludge conveying structure 6, the sludge conveying structure 6 comprises a rotating column 61, the rotating column 61 is rotatably connected in the feeding cover 5, and the outer surface of the rotating column 61 is fixedly connected with a plurality of mud pushing plates 62.

[0037] The feeding cover 5 is the inlet of the sludge into the sludge drying filter cartridge 2, and the feeding cover 5 is inclined in the application. By controlling the rotating column 61 to drive the plurality of mud pushing plates 62 to rotate, the sludge in the sludge drying filter cartridge 2 can smoothly enter the sludge drying filter cartridge 2 through the feeding cover 5.
