Description

Technical Field

[0001] The utility model relates to the technical field of sludge dryers, and more specifically, to a cleaning device for a sludge dryer. Background Technique

[0002] The disk dryer can be applied to the drying and reduction of various municipal sludge and industrial sludge. It consists of a double-layer outer shell and a rotor with hollow disks. Adjustable-angle pusher devices are installed on the disks. During operation, it can not only heat the materials but also push the materials forward. However, sludge has a certain viscosity. After the dryer is used, its interior needs to be cleaned to improve the service life of the dryer.

[0003] After retrieval, the utility model patent with the publication number CN208471873U discloses a cleaning device for a disk-type sludge dryer, including a machine base and a drying box. A first support frame is fixedly connected to the bottom end of the machine base. Motors are fixedly connected to both ends of the upper surface of the machine base. One side of each motor is rotationally connected to a rotating shaft. The end of the rotating shaft far from the motor is fixedly connected to a driving wheel. A drying box is provided between the two motors. The drying box is fixedly connected to the upper surface of the machine base. A driving shaft is rotationally connected inside the drying box. This patent can not only quickly dry the sludge, but also the waste gas generated inside can be micro-treated through a filter and then purified and released. The cleaning device and the discharge device provided inside the drying box can quickly clean the roller and the inner wall of the drying box. Its working efficiency is greatly improved, and the time spent on cleaning is also greatly shortened. The mechanical integrated operation can save manpower, provide more guarantees for subsequent other work, and is more environmentally friendly, achieving sustainable development. However, the above patent still has the following deficiencies: The water sprayers and nozzles for cleaning the dryer are always located in the drying box. Dried sludge is likely to be lifted inside the drying box, thus blocking the nozzles and affecting the effect of water spray cleaning. In addition, the positions of the nozzles are fixed, and the cleaning effect on the drying box is not good. For this reason, we propose a cleaning device for a sludge dryer.
