Background
In the long-term maintenance work of equipment such as ironmaking, sintering and dust collectors, the dust collector air duct is found to cause the dust-removing dust particles to scrape and grind a plurality of positions of the air duct due to the angle (such as the elbow air duct shown in fig. 4), so that the phenomena of abrasion and leakage of the air duct often occur around the air duct, especially the bottom of the elbow air duct (part A in fig. 4) and the bottom of the straight air duct (part B in fig. 4) are abraded most seriously, and the phenomena of accumulation and leakage of the dust-removing dust on site and the like are caused. For the situation, the conventional method is to reinforce the steel plate in the wear area, and because the reinforced steel plate only can prolong the service time of the patching area, the steel plate is not easy to weld, and the welded part is easier to wear and break, the service time is still not long enough, and the hidden trouble problem caused by wear cannot be fundamentally solved.
In order to ensure the normal use of the dust remover and not to influence the production, the shape of the elbow of the air duct is changed, the ceramic wear-resistant layer is attached and the wear-resistant part is arranged, and then the air duct is put into use, so that the wear problem is effectively solved, and the service life of the air duct is prolonged.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve provides a wear-resisting wind channel of dust remover, can reduce the wearing and tearing in wind channel, and extension live time guarantees the normal operating of dust remover, guarantee production.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the utility model provides a wear-resisting wind channel of dust remover, includes the wind channel body, the wind channel body includes interconnect's straight wind channel and elbow wind channel, and the tip in straight wind channel and elbow wind channel all is provided with the flange that is used for the connection, the bottom turn in elbow wind channel sets up to quarter turn, top turn sets up to the arc turn, the quarter turn in elbow wind channel is filled and is laid the wearing part that the one deck formed by wear-resisting material for the wearing part of arc turn, the bottom in straight wind channel by the top that wear-resisting material formed, all paste on the lateral wall in straight wind channel and elbow wind channel and mend the ceramic wearing layer.
The utility model discloses technical scheme's further improvement lies in: the air duct body is a rectangular air duct with a rectangular cross section or a circular air duct with a circular cross section.
The utility model discloses technical scheme's further improvement lies in: the ceramic wear-resistant layer is attached to the outer surfaces of the side walls of the straight air duct and the elbow air duct.

Detailed Description
The present invention will be described in further detail with reference to the following examples:
as shown in figures 1-3, a dust collector abrasion-resistant air duct comprises an air duct body, wherein the air duct body is a rectangular air duct with a rectangular cross section or a circular air duct with a circular cross section. The air duct body comprises a straight air duct 1 and an elbow air duct 2 which are connected with each other, flanges 3 used for connection are arranged at the end parts of the straight air duct 1 and the elbow air duct 2, and the air duct can be changed in any length and any angle through connection of the flanges 3.
The bottom turn of elbow wind channel 2 sets up to quarter turn, top turn and sets up to the arc turn, the quarter turn of elbow wind channel 2 is filled the top that is formed by wear-resistant material and is laid the wearing part 4 that the one deck formed by wear-resistant material for the wearing part 4 of arc turn, the bottom in straight wind channel 1, and wearing part 4 upwards extends the take the altitude along preceding, back both sides wall, covers the kneck of preceding, back both sides wall and bottom, plays certain intensive effect to the kneck department, prevents the kneck wearing and tearing. The wear-resistant material of the wear-resistant part 4 is high-chromium wear-resistant alloy. The ceramic wear-resistant layers 5 are attached to the side walls of the straight air duct 1 and the elbow air duct 2, and the alumina content of the ceramic wear-resistant layers 5 is not lower than 95%. The side walls include two side walls and an upper side wall and a lower side wall. The ceramic wear-resistant layer 5 is attached to the outer surfaces, but not the inner surfaces, of the side walls of the straight air duct 1 and the elbow air duct 2, so that the phenomenon that the ceramic wear-resistant layer is worn for a long time and falls into the air inlet duct to block the air duct or even cause safety accidents can be avoided.
