Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 , figure 2 As shown, the embodiment of the sealing device of the present invention includes a wiper 4, a base 5 and a fixing mechanism. Further, the fixing mechanism includes a connecting rod 1 and a positioning structure for determining the position of the wiper 4 in the fire viewing hole (fire stand) 600 through the connecting rod 1 . Furthermore, the positioning structure includes a positioning part 2 , a sleeve 3 and a supporting part 31 .

[0025] Specifically, the wiper 4 is columnar, preferably cylindrical, and its outer diameter can be flexibly changed according to the inner diameter of the fire viewing hole 600 . The center of the wiper 4 can be a cavity or solid, but its side surface is smooth to smooth the grout on the inner wall of the fire hole 600 . Although the outer diameter of the wiper 4 ...

Abstract

The invention provides a sealing device and method for a fire observation hole of a coke oven. The sealing device comprises a wipe repairing device, a base and a fixed mechanism, wherein the wipe repairing device is of a column shape, the side surface of the wipe repairing device is smooth, the outer diameter of the wipe repairing device is smaller than the inner diameter of the fire observation hole, the wipe repairing device is used for stretching into the fire observation hole, and when the wipe repairing device stretches into the fire observation hole, a gap for being filled with grouting materials is formed between the wipe repairing device and the side wall of the fire observation hole to enable the grouting materials to permeate into a brickwork joint of the fire observation hole; the base is fixed at the lower end of the wipe repairing device, the outer diameter of the base is smaller than the inner diameter of the fire observation hole and is larger than that of the wipe repairing device, and the base is used for obstructing the grouting materials so as to avoid the falling of the grouting materials when the grouting materials are poured into the periphery of the side surface of the wipe repairing device; and the fixed mechanism is connected with the upper end of the wipe repairing device and is used for stably positioning the wipe repairing device into the fire observation hole of the coke oven. According to the sealing device and the sealing method, the grouting materials can be rapidly and conveniently poured into the brickwork joint of the fire observation hole, are firmly positioned and do not fall, and furthermore, the coal feeding operation is not influenced.

Description

technical field [0001] The invention relates to the technical fields of coke oven body maintenance and furnace body sealing, in particular to a coke oven flame viewing hole sealing device and method. Background technique [0002] Coke oven, also known as coke oven, is the main thermal device for coking. A coke oven generally includes a carbonization chamber, a combustion chamber, a regenerator, a chute area, a roof, a foundation, a flue, etc. The coal material in the carbonization chamber is heated and turned into coke under the condition of air isolation. A coke oven has dozens of carbonization chambers and combustion chambers arranged alternately and separated by refractory materials. Each combustion chamber has multiple fire channels. The preheated gas from the regenerator (gas with high calorific value is not preheated) and air meet and burn at the bottom of the flue, and provide heat to the carbonization chamber from the side. The regenerator is located in the lower...
