Split type disc sludge drying machine

Abstract

The invention provides a split type disc sludge drying machine, which comprises a split type shell, a split type hollow shaft system, a driving device system and a discharging device, wherein the split type shell and a foundation are fixedly installed, the split type hollow shaft system is mounted in the split type shell, the driving device system is arranged on the driving side of the split type shell and connected with the hollow main shaft of the split type hollow shaft system to drive the hollow main shaft to rotate, the other side of the split type shell is a steam inlet side, the discharging device is installed on the split type shell and is close to the steam inlet side, the split type hollow shaft system comprises the hollow main shaft, a plurality of detachable discs, a siphon elbow and a rotary joint, the interior of the hollow main shaft is of a cavity structure, guide pipes for steam and condensate water to flow in and out of the disc cavity are distributed on the hollow main shaft, the discs are detachably mounted on the hollow main shaft at equal intervals, the cavities of the discs are communicated with the hollow main shaft, the siphon elbow is mounted on the steam inlet side, the siphon elbow is connected with the rotary joint, and the other end of the rotary joint extends into the hollow main shaft.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment and environmental protection equipment, and in particular relates to a split disc sludge dryer. Background technique [0002] With the continuous and rapid development of my country's economy, the urban process and industrialization process continue to increase, the types of sludge produced by human beings in life and production activities are increasing, and the amount of sludge produced is increasing. The main sludge output includes domestic sewage sludge, industrial sewage sludge, water supply sludge, river dredging sludge, water supply and drainage pipe network sludge, etc. Among them, the output is the largest, the degree of pollution is the highest, the most harmful and the most difficult to dispose of The most important is domestic and industrial sewage sludge. The country is paying more and more attention to environmental protection, and environmental protection policies are beco...

AI Technical Summary

Problems solved by technology

The hollow paddle sludge dryer adopts a double-shaft screw system. Compared with the disc sludge dryer, it has the same sludge processing capacity. The hollow paddle sludge dryer occupies a large area and has a complex structure. Low conversion efficiency, easy to stick to the wall, relatively troublesome operation and maintenance

For the disc sludge dryers currently on the market, since the disc and the hollow shaft are welded as a whole, when the disc is worn out and steam leaks, it will take time and effort to repair and maintain, and one or several of the discs will be damaged. The entire hollow shaft system will be scrapped, resulting in waste of materials and increased equipment costs of the sludge treatment factory; during installation and maintenance of the integrated hollow shaft system, due to the weight of more than ten tons, the disassembly and installation of the entire shaft is also very troublesome, which is harmful to the plant. The requirements and maintenance of auxiliary facilities are very demanding
