Description

A kind of hot axis of sludge drier disk and sludge drier

Technical field

The utility model relates to a kind of hot axis of disk, in particular to the hot axis of a kind of sludge drier disk and drying sludge Machine belongs to drying sludge technical field.

Background technique

Sludge is the by-product after sewage treatment plant's sewage treatment, is one kind by organic debris, microorganism, inorganic particulate The extremely complex heterogeneous body of the compositions such as grain, colloid；Sewage treatment capacity and handling rate rapid development, while also bringing dirt Mud yield increases sharply.Pollution caused by sludge is arbitrarily stacked has been highlighted with recontamination problem, causes society The concern of all circles, has also pushed the formation in sludge treatment market, and the demand of specific resistance to filtration is just increasingly urgent to.At Treatment of Sludge The target set is to realize the minimizing of sludge, stabilisation and innoxious；It encourages recycling and using the energy and resource in sludge, reaches To energy-saving and emission-reduction and the purpose developed a circular economy.Burning after sludge machinery heat drying has the excellent of minimizing and high stability Point.

One most important component of sludge drier is exactly the hot axis of disk, as shown in fig. 6, including main shaft and being placed equidistant with Hollow disc on the main shaft achievees the purpose that heat sludge, hollow disc one by being passed through hot steam into hollow disc As be to be welded by two disk bodies, since the size of disk is larger, it is serious to be passed through hot air holes deformation, therefore, disk also Equipped with support nail, guarantee that two disk bodies will not crack because of deformation, the both ends of support nail are generally welded to two disk bodies On outer wall；When due to disk body work, can not stall, biggish friction is generated between sludge, it is easy to by support nail and disk body Between weld seam grind away, cause hot steam to escape, be a very big security risk, it is necessary to stop production maintenance.

At gating location, material enters in hothouse, between first disk and equipment end cap, material because not to The thrust of end movement, material are difficult autorotation movement, and hardness is got higher after desiccation, and accumulative meeting is to disk surface and branch for a long time The abrasion of damaging property of nail weld seam, will also result in gas leakage.

As long as accumulative meeting is to deep bid for a long time in addition, material of entering at terminal discharge mouth position is difficult autorotation and comes out The destructive abrasion of precocity also wears support nail weld seam, causes gas leakage；And sludge also has combustibility, and long term wear is also The phenomenon that meeting sounding produces fire by friction.

In addition, the material scraping plate of feed end can wipe the sludge fed on end disc off, avoid accumulating to disk for a long time The abrasion of damaging property of face.

Further, the top of the disk is in blunt knife tooth shape.

Further, the top of the disk is equipped with mud guiding plate.

Further, the radial direction of the mud guiding plate and the disk is in 45 °.

Beneficial effect using above-mentioned further technical solution is: can play the role of more preferably leading mud, and can stir dirt The effect of mud.

Further, the mud guiding plate on multiple disks is helically arranged on the whole.

The invention further relates to a kind of sludge driers using the hot axis of above-mentioned disk.
