AI Technical Summary
The wear-resistant bending pipe of the dust collector in the sintering operation area of the sintering plant is short in service life, which is prone to damage to the pipe wall due to the wear of wind pressure and ash materials, and the misalignment of the bolt holes at the flange connection leads to ash spray, resulting in air pollution and high maintenance costs. .
The wear-resistant bent pipe design is adopted with a movable flange and a silicon carbide wear-resistant layer to increase connection stability and wear resistance. By setting up a wear-resistant cavity on the outside of the bent pipe and a 12mm thickness silicon carbide wear-resistant layer is built to reduce wear. And use sealing rubber at the flange connection to prevent air and dust leakage.
The service life of wear-resistant bend pipes has been extended from 2 months to 10 months, reducing maintenance costs and spare parts costs, reducing environmental pollution, and improving operating rates and labor intensity for workers.

[0012] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0013] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.
[0014] like Figure 1 As shown, the wear-resistant elbow of the utility model comprises an elbow 3 connected to the axial diameter of the discharge port of the silo type pump body, and is characterized in that the elbow is connected to the axial diameter of the discharge port through a movable flange 1, a wear-resistant cavity 2 is provided on the outer stress-bearing surface of the elbow 3, and a wear-resistant layer 4 is provided on the inner side of the wear-resistant cavity 2.

[0017] A sealing rubber 5 is provided at the connection of the movable flange 1 .
[0018] The angle of the elbow 3 is 100°.
[0019] The wear-resistant elbow of the utility model changes the fixed flange connection of the wear-resistant elbow into a movable flange 1 connection, thereby increasing the stability and sealing of the connection and avoiding air leakage and dust leakage caused by the misalignment of the flange hole.

The end face of the movable flange 1 is provided with a baffle, and a sealing rubber 5 is provided at the connection of the movable flange 1.
[0020] On the outside of the elbow 3, the main force-bearing side is equipped with a wear-resistant cavity 2, and a wear-resistant layer 4 is installed in the wear-resistant cavity 2 to increase the rigidity and strength of the elbow 3. The wear-resistant material installed in the elbow 3 is improved, and the thickness of the wear-resistant layer 4 is appropriately increased to increase the wear resistance. The 90° angle of the wear-resistant elbow is too impact-resistant, and the angle is improved to 100° to reduce the impact.
[0021] The wear-resistant elbow of the utility model has a service life of 2 months before improvement, and its service life is increased to 10 months after improvement. The wear-resistant elbow can save a large amount of money every year, greatly improves the operation rate of the wear-resistant elbow, reduces the labor intensity of workers, reduces environmental pollution, and greatly reduces the maintenance cost and spare parts cost of the wear-resistant elbow.
