Pneumatic elevator deslagging pipe capable of effectively reducing pipe wall abrasion

The utility model discloses a pneumatic elevator deslagging pipe capable of effectively reducing pipe wall abrasion. The pneumatic elevator deslagging pipe comprises a deslagging pipe, a slag stopping cover and a bolt pair, wherein the deslagging pipe is horizontally arranged, and an abrasion-resistant material lining is arranged on the inner wall of the deslagging pipe; one end of the deslagging pipe is connected with a pneumatic elevator, and the other end of the deslagging pipe is fixedly connected with a large end of the slag stopping cover by virtue of the bolt pair; the slag stopping cover is in a right-angled trapezoid shape, right-angle sides are horizontally placed, and an opening faces downwards; the length of the slag stopping cover is 2-3 times of the diameter of the deslagging pipe; an upper cover plate and a rear end plate of the slag stopping cover are flat panels or arc-shaped plates; and an inclined angle of the upper cover plate of the slag stopping cover is 20-30 degrees in a horizontal direction. According to the pneumatic elevator deslagging pipe disclosed by the utility model, the service life of the slag stopping cover can be prolonged by adopting a method of arranging the slag stopping cover at a deslagging opening of the deslagging pipe; the abrasion-resistant material lining is arranged on the inner wall of the deslagging pipe so as to ensure that the service life of the deslagging pipe can be prolonged; and the pneumatic elevator deslagging pipe is simple in structure, convenient to install and reliable to operate, and ensures that the abrasion of the deslagging pipe and the slag stopping cover can be effectively reduced.
