Among the figure

The 1-dram, 2-chain, 3-axle, 4-feed(raw material)inlet, 5-material outlet, 6-flight.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.

As shown in Figure 1, a kind of drier for industrial sludge, the dram 1 and a plurality of flights 6 that are arranged on dram 1 inwall that comprise inner hollow, dram 1 two ends are respectively arranged with feed(raw material)inlet 4 and material outlet 5, in addition, also be provided with clearing device and shredder assembly on dram 1 inwall, clearing device is the chain 2 that a plurality of ends and dram 1 inwall are fixedly connected, and the dram 1 inwall quantity of closing on the chain 2 that feed(raw material)inlet 4 is provided with is closed on the quantity of the chain 2 that described material outlet 5 is provided with greater than dram 1 inwall.Shredder assembly is the axle 3 that runs through dram 1 and parallel setting with dram 1, and axle 3 is arranged on the shaft core position of dram 1, axle 3 is provided with a plurality of projectioies and every adjacent two projectioies are connected to each other, and a plurality of projectioies form screw thread form along axle 3 extension directions.

Principle of work of the present invention below is described in detail in detail.

Material 4 is sent into from the feed(raw material)inlet, material can be attached on the flight 6 and chain 2 of feed(raw material)inlet 4, when dryer is worked, material can depend on flight 6 and chain 2 rolls along with the rotation of dram 1, when material peaks along with dram 1, because action of gravity, material can fall, just in time drop on the axle 3 that is positioned at dram 1 shaft core position, at this moment, 3 pairs of materials of axle carry out fragmentation work, material after the fragmentation can drop on the flight 6 and chain 2 on the dram 1 once more, after the rotation for several times, if the sticking agglomerating phenomenon of wall of material then can appear in traditional dryer, but the design adopts chain 2 this clearing devices can effectively prevent the generation of the sticking agglomerating this phenomenon of wall, when dram 1 rotation, because chain 2 one ends are fixed, the other end is unfixing, fixed one end is along with dram 1 rotation, when chain 2 fixed one end rotates to vertex, the material that is attached on the chain 2 will be along with chain 2 unfixed end motions, because the effect of gravity, chain 2 unfixed ends can just in time drop on the axle 3, at this moment, the material that is attached on the chain 2 also can fall along with chain 2 unfixed ends, and just in time drops on the axle 3 that is positioned at dram 1 central shaft position, reach material grinding, go round and begin again, like this can be effectively broken once more, material is not attached on the inwall of dram 1, reduce the waste of material, and saved cost.
