In the production process of the coke oven, the phenomenon of furnace roof serial leakage caused by the falling of mortar in brick seams is more obvious, so that the temperature of a furnace roof space is directly caused to be higher, raw coke gas generated in the coking process is extremely easy to decompose, the yield of the raw coke gas is directly reduced, and the heat loss of the coke oven is increased. Graphite produced by the decomposition of raw coke oven gas is attached to the parts of the oven wall, the coal charging port, the top of the carbonization chamber and the like, so that the normal production of the coke oven is affected. Therefore, the furnace top blowby phenomenon brings serious hidden trouble to the quality of the coke oven.
As the furnace age increases, the temperature of the furnace body changes, the refractory bricks expand, and the mortar in individual brick joints further falls off due to the occurrence of pressure difference between the inside and the outside of the furnace, so that the phenomenon of serial leakage is particularly obvious. However, in the repairing process, due to factors such as high furnace temperature, deep position of the serial leakage part, small diameter of the temperature measuring eye and the like, a hot repairing operator cannot repair the serial leakage part in a short distance. At present, the conventional repair is to adopt a conical block and weld a long operating rod, put the asbestos rope fastened into a circle into a temperature measuring hole, probe the conical block into the asbestos rope loop, squeeze the asbestos rope through the conical block and then perform grouting, so as to achieve the purpose of plugging the temperature measuring hole, and the effect is also obvious. However, this grouting device has the following disadvantages:
