Embodiment 1

[0041] Such as image 3 (A) and image 3 (B) The sintering machine trolley of this embodiment, the area of ​​the trolley is 400m 2 , It includes upper fence 3, lower fence 2 and trolley body 1. The seals between upper fence 3 and lower fence 2 and between lower fence 2 and trolley body 1 are respectively provided with elastic sealing strips 4. The elastic sealing strip 4 is a metal graphite sealing strip, which is a strip structure formed by crimping a layered structure, and the layered structure includes a metal layer 401 and a graphite layer 402. The graphite layer 402 is embedded and pressed on the upper and lower surfaces of the metal layer 402. The seals between the upper fence 3 and the lower fence 2 and between the lower fence 2 and the trolley body 1 are provided with mutually matched bosses and grooves. The elastic sealing strip 4 is pressed into the concave by the bosses. In the slot.

Abstract

The invention discloses a sintering machine trolley provided with an elastic sealing strip, which belongs to the field of sintering equipment. It includes an upper fence, a lower fence and a trolley body. Elastic sealing strips are respectively provided at the seals between the upper fence and the lower fence and between the lower fence and the trolley body. The sealing strip is a metal graphite sealing strip. The elastic sealing strip is a strip structure formed by curling a layered structure, and the layered structure includes a metal layer and a graphite layer, and the graphite layer is respectively inlaid and pressed on the upper and lower surfaces of the metal layer. Under repeated heat alternating environment, the seal between the upper and lower fences and the seal between the lower fence and the trolley body become irregular due to high temperature. The elastic sealing strip of the present invention has certain elasticity, and its elastic deformation It can supplement the irregular space in the sealing place, thereby greatly improving the sealing performance between the upper and lower fences and between the lower fence and the trolley body.

Description

technical field [0001] The invention belongs to the field of sintering equipment, and particularly relates to an elastic sealing strip provided between the upper and lower fences and between the lower fence and the trolley body so as to greatly improve the sealing performance between the fences and between the fence and the trolley body. Improved sintering machine trolley. Background technique [0002] Sintering is a process in the ironmaking process. The process is to roast iron ore powder into sintered ore, which is one of the main raw materials for blast furnace ironmaking. The sintering machine trolley is an important equipment in the sintering process. During the work, many trolleys are connected together and sealed by the end surface contact of the trolley fence. Due to long-term work under heavy load and high temperature, the fence is deformed, and gaps appear on the contact surface of the trolley fence. Cause air leakage and a lot of heat leakage during sintering, ...
