The upper and lower ends of the four bent steel plates 1 are provided with a first high-temperature resistant canvas 2, and the upper end of the first high-temperature resistant canvas 2 is provided with a second high-temperature resistant canvas 3.

[0017] In this embodiment, the first high-temperature resistant canvas 2 and the second high-temperature resistant canvas 3 are respectively the inner lining high-temperature silicone canvas and the outer lining high-temperature silicone canvas.

[0018] Four bent steel plates 1 are 4mm thick and 100mm long, and are bent at 90° to form an integral flange.

[0019] The first high-temperature resistant canvas 2 has a width of 50mm and a thickness of 5mm and is located at one end of the integral flange. The second high-temperature resistant canvas 3 has a width of 180mm and a thickness of 5mm and is located at both ends of the integral flange.

[0020] The first high-temperature resistant canvas 2 and the second high-temperature resistant canvas 3 are both fixedly connected to the overall flange by thin flat strips 4 and wing bolts 5. The first high-temperature resistant canvas 2 is 50mm wide and 5mm thick, and is fitted on the overall flange formed by four bent steel plates 1. The second high-temperature resistant canvas 3 is fitted on the upper end of the first high-temperature resistant canvas 2.

[0021] First, use 4mm thick, 100mm long high-temperature resistant stainless steel plates to be bent into 90° unequal angle steel to form an integral flange. Then, wrap one end of the flange with a 5mm thick, 50mm wide inner lining of high-temperature silicone canvas. Next, wrap the entire flange with a 5mm thick, 180mm wide outer lining of high-temperature silicone canvas. Finally, tighten the flange, high-temperature silicone canvas, and other wing bolts with thin flat strips.

[0022] The fan can bear the heat generated by the friction in the pipeline during operation, does not appear rupture and deformation, and can make the fan inlet and outlet and the furnace pipeline connection play a damping role, can greatly prolong the service life, and achieve the requirements of customers.
