The present invention relates to a device for attaching an injection device to a charging vehicle to seal a gap with a refractory smoke inside a coke oven carbonization chamber, and more particularly, to a silica lead constituting a carbonization chamber for producing coke. The dry mortar spraying operation, which seals the slip joint portion, which is a contact portion between the and the chamotte smoke, is attached to a charging vehicle, which is a facility to inject coal into a carbonization chamber, to automatically perform All the processes required for the spraying of mortar are automated to facilitate the mortar spraying operation, and such a device is mounted in a charging vehicle for the manufacture of coke and moved with the charging vehicle, thereby making coal Manufacturing efficiency of coke is not necessary because it is not necessary to move the charging vehicle performing the charging operation to the outside of the position where the mortar spraying operation is performed. Powder a mortar can be improved relates to an automatic injection device.

In general, a coke oven facility is provided with a plurality of carbonization chambers, and coke is manufactured by injecting bituminous coal, which is a kind of coal, into the carbonization chambers.

Thus, the coke oven for producing coke is composed of refractory follicles, the lower part is constructed with silica and the upper part is constructed with chamotte.

In order to manufacture the coke, the bituminous coal for production should be introduced to the site where the silica lead is constructed through the coal inlet.

In this way, when coal is injected into the coke oven to the construction site with silica lead, coal at room temperature comes into contact with the silica lead maintained at about 1300 ° C. Since the chamotte is not in contact with the coal at room temperature, the original state is maintained, and the temperature inside the carbonization chamber is increased in the process of manufacturing the coal injected into the carbonization coke. As the temperature rises to a temperature similar to that of the temperature, the expanded and reconstructed state is recovered from the contracted state. Thus, the silica strand, which repeats the contraction and expansion, and the chamotte strand, which always maintains its initial state, maintains an appropriate bond state. In order to be able to, the silica lead and chamotte lead is in contact It makes an artificial sliding on the part of the slip joint.

However, this sliding part is damaged by continuous sliding as the production of coke is repeated. In order to repair the sliding part, a powder-like mortar similar to a mist is applied to a closed carbonization chamber. In addition, it adopts a repairing method that ejects into the carbonization chamber to create a + pressure and causes the mortar to be fused as it slips out of the sliding part that is damaged and has a gap.
