Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides an embodiment of:

a heat-conducting air pipe with a heat insulation mechanism for a rotary kiln comprises:

the device comprises a device main body 01, wherein the device main body 01 comprises an air guide pipe 110, the two sides of the air guide pipe 110 are both connected with connectors 111, four corners of each connector 111 are provided with bolt holes, and the air guide pipe 110 is communicated with the insides of the two connectors 111;

thermal-insulated structure 02, thermal-insulated structure 02 includes aerogel carpet veneer 210, aerogel carpet veneer 210 embedding is installed on the inner wall of guide duct 110, be connected with ceramic layer 211 on aerogel carpet veneer 210's the inner wall, weight promotion is not obvious when having increased the thermal-insulated layer thickness of device main part 01 itself, can carry out effectual thermal-insulated and prolonged the art of device with the life-span like this, device main part 01 loss of use has been reduced, the installation frequency of staff has been alleviateed, let whole practicality higher through simple structure.

Further, the outside of two ceramic layers 211 all is connected with sealed 112, and sealed 112 both sides all are connected with the double faced adhesive tape, can seal the erection joint department of tuber pipe, and the prevention air current flows out through the gap and produces the damage to the device, also can glue the pre-fixation to the erection department when needs install and improve the installation effectiveness of guide duct 110.

Furthermore, the inner walls of the two connectors 111 are connected with filter screens 113, so that a lot of dust and floatable objects can be generated when the rotary kiln operates, the dust and particle floating objects can be filtered through the filter screens 113, and the floating objects are prevented from entering the air to pollute the air.

Further, two filter screens 113 and interface 111's connection be for dismantling the connection, and a lot of dust and granule floater can be attached to the surface of filter screen 113 under long-term work, and the gas permeability that can lead to filter screen 113 like this reduces and leads to wind-force to be obstructed in air guide pipe 110, can dismantle to connect and make things convenient for the staff to dismantle filter screen 113 with trading.
