Abstract
The invention consists of inner and outer layers. The inner layer is the packing capable of resisting high temperature of 300 deg. and the outer layer is asbestos cloth with copper or stainless steel wire. The packing is wrapped in the asbestos cloth to be in a P-shape.
Description
Affiliated technical field
The present invention relates to a kind of sealing ring of large smoke dustproofing converter for coke oven.
Background technique
The metallurgy industry collecting smoke dust from coke oven adopts rubber material mostly with the seal ring on the large-scale conversion equipment at present, and is easily aging under worst hot case though sealing is reliable, has a strong impact on the sealability of flue gas ash removal conversion equipment, and working life is short.
Summary of the invention
Easily aging with the seal ring on the large-scale conversion equipment in order to overcome existing metallurgy industry collecting smoke dust from coke oven, the deficiency that lack working life the invention provides a kind of collecting smoke dust from coke oven that can use for a long time with large-scale conversion equipment seal ring under worst hot case.
The technical solution adopted for the present invention to solve the technical problems is, a kind of sealing ring of large smoke dustproofing converter for coke oven, form by inside and outside two layers, internal layer be can anti-300 ℃ of high temperature packing, skin is knitted the asbestos cloth of copper wire or Stainless Steel Wire in being, knit in packing is wrapped in the asbestos cloth of copper wire, form the P word shape.
The invention has the beneficial effects as follows adopt in soft outer structure just, make packing favorable elasticity and in knit the asbestos cloth of copper wire corrosion resistance organically combine, can for a long time anti-250 ℃ high temperature, cold-and-heat resistent variation stable performance, long service life.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the tectonic maps of present embodiment;
Among the figure: 1. packing; 2. asbestos cloth.
Embodiment
As shown in Figure 1, the seal ring of the large-scale conversion equipment of a kind of collecting smoke dust from coke oven is formed by inside and outside two layers, and internal layer is a packing 1, outer asbestos cloth 2, knit in packing 1 is wrapped in the asbestos cloth 2 of copper wire or Stainless Steel Wire, form the P word shape, packing 1 can anti-300 ℃ of high temperature, asbestos cloth is woven with copper wire for 2 li, the corrosivity of high temperature resistant flue gas is good, and cold-and-heat resistent changes stable performance, long service life.
Claims (4)
