Description

Technical Field

[0001] The utility model relates to the technical field of sludge dryers, and more specifically, to a novel sludge dryer. Background Art

[0002] A sludge dryer is an indirectly heated low-speed stirring dryer. There are two or four hollow rotating shafts inside the device. The hollow shafts are densely arranged with fan-shaped wedge-shaped hollow blades in parallel. The structure is specially and ingeniously designed. The shafts rotate relative to each other, and by using the principle and structure that the angular velocity is the same while the linear velocity is different, the self-cleaning effect of the sludge on the shafts is achieved ingeniously, and the "shaft sticking" phenomenon during the sludge drying process is prevented to the greatest extent.

[0003] After retrieval, the utility model patent with the publication number of CN220393526U discloses a novel sludge dryer, which includes a housing, a main shaft and a disc. Two main shafts are arranged inside the housing. The main shafts are hollow shafts. Multiple rows of discs are arranged perpendicular to the axis of the main shafts and deflected. The discs are of a fan-shaped ring hollow structure. The disc cavities are communicated with the main shaft cavities. The discs on the two main shafts are arranged in a staggered and crossed manner; the lower half of the housing, the main shafts and the discs are all made of plates formed by at least two alloy layers; in this novel sludge dryer, a baffle plate is arranged in the sludge easy-to-stick area. The baffle plate cooperates with the discs to break the sludge blocks attached between the discs, improve the heat exchange efficiency, and can effectively prevent the "shaft sticking" phenomenon from occurring, without the need for a dry mud backmixing process. However, the above patent still has the following deficiencies: The material inlet is located at the top of the dryer, which is not convenient for feeding the sludge. In addition, after the sludge is dried, it is mostly powdery dust, which is easy to generate dust when discharged, affecting the surrounding environment. Therefore, we propose a novel sludge dryer.
