Problems solved by technology

The furnace top coal loading car uses an electromagnet to pick up the coal charging cover. During this process, the small and light cast iron fire viewing hole cover is easily sucked and dropped into the carbonization chamber, resulting in poor sealing of the vertical fire channel and air and sundries entering the vertical furnace. Flue path, leading to temperature disorder, coke oven production disorder

Embodiment Construction

[0016] Such as figure 1 , figure 2 Shown is a kind of in the coal charging process provided by the present invention, can not cause the fire hole cover to be sucked off by the electromagnet, the fire hole cover structure that is used for the vertical fire channel of the coke oven combustion chamber of top-loading. The fire hole cover structure includes a cover base 1 and a cover body 2, and the fire hole cover structure also includes a connection locking mechanism 3, and the cover body 2 is detachably fixed by the connection locking mechanism 3 On the cover base 1, the fire viewing hole 4 on the cover base 1 is closed. Like this, the cover seat 1 and the cover body 2 constituting the firehole cover structure are detachably connected together by setting a connection locking mechanism 3 . In this way, since the cover base 1 and the cover body 2 are no longer connected to the cover base 1 by the self-weight of the cover body 2, the connection locking mechanism 3 is added to co...

Abstract

The invention discloses a fire-watching hole cover structure, particularly discloses the fire-watching hole cover structure for vertical flues of a top-charging coke oven combustion chamber, and belongs to the technical field of design and manufacturing of metallurgical production equipment accessories. Provided is the fire-watching hole cover structure which is used for the vertical flues of the top-charging coke oven combustion chamber and cannot cause a fact that a fire-watching hole cover is absorbed off by an electromagnet during a coal charging process. The fire-watching hole cover structure includes a cover seat and a cover body; the fire-watching hole cover structure also comprises a connection locking mechanism; the cover body is detachably fixed on the cover seat through the connection locking mechanism and seals a coke charging hole on the cover seat.

Description

technical field [0001] The invention relates to a fire viewing hole cover structure, in particular to a fire viewing hole cover structure used for a vertical flue of a top-loaded coke oven combustion chamber, and belongs to the technical field of design and manufacture of metallurgical production equipment accessories. Background technique [0002] In the existing coke oven, each combustion chamber is generally provided with 32 vertical fire passages, and a fire viewing hole is arranged on the top of each vertical fire passage as a temperature measurement point. Since the combustion system is under negative pressure, in order to prevent excess air and sundries from leaking into the combustion chamber, a fire hole cover is provided on the top of each fire hole. The fire hole cover includes a fire hole seat and a fire hole cover. The fire hole seat is embedded in the fire hole block, and the fire hole cover is covered on the fire hole seat by its own weight to realize the seal...
