Connecting device of furnace end smoke collection pipeline

Abstract

The invention discloses a connecting device of a furnace end smoke collection pipeline, relates to a coal charging smoke collection device of a tamping coke furnace, and solves the technical problems of inaccuracy for butting, poor sealing effect and incapability of normally collecting furnace end smoke in a conventional blind sleeve. The connecting device comprises a flap valve switching-on device and a blind sleeve butting device, and is used for communicating an upper pipeline with a lower pipeline; a flap valve drive oil cylinder of the flap valve switching-on device is connected with a push rod; a blind sleeve butting drive oil cylinder of the blind sleeve butting device is hinged to a swing arm, and the other end of the swing arm is connected with a blind sleeve; a vertical limiting block is mounted at the joint between a blind sleeve body and the swing arm, and a ceramic fiber blanket sealing ring is arranged on the edge of a butting hole of the blind sleeve body. The connecting device is used for connecting the upper and lower pipelines of the furnace end smoke collection pipeline and has the advantages of space saving, simple structure, accuracy for alignment, good sealing effect and the like.

Description

technical field [0001] The invention relates to a coal-charging smoke dust collection device for a ramming coke oven, in particular to a connection device for a smoke collection pipeline at the furnace head of a ramming coke oven. Background technique [0002] The tamping coke oven adopts the form of side-loading coal, which has the advantages of low investment cost and high production efficiency, and has become the mainstream furnace type in China. However, the disadvantage of side-loading coal is that a large amount of raw gas will be generated at the furnace mouth when charging coal, and these raw gas will escape into the atmosphere and seriously pollute the environment. People are also making continuous efforts to control the waste gas produced by the side-loading coal furnace mouth. [0003] In the prior art, there is a smoke collection pipeline at the top of the burner, and its structure is as follows: figure 1 , 2 Shown: Furnace head smoke collection pipeline 1 is ...
