Description
Technical Field
The invention belongs to the technical field related to coke ovens, and particularly relates to a remote wall repairing device for a coke oven.
Background
Coke ovens, a furnace typically built of refractory bricks and refractory blocks, are used to char coal to produce coke. When an enterprise produces coke by using a coke oven, coal powder is generally beaten on a coal supporting plate to prepare coal cakes, and then the coal cakes are conveyed into the oven of the coke oven by the coal supporting plate. The width of the coal supporting plate is slightly smaller than the distance between two furnace walls of the coke oven, so that the coal supporting plate and the coal cakes arranged on the coal supporting plate can enter the coke oven along the two furnace walls of the coke oven. When discharging, the coke prepared in the coke oven is discharged outwards from the coke pushing plate, so that the blocky coke is inevitably dropped into the coke oven in the process, and a hammer head for hammering the pulverized coal is seriously dropped into the coal cake and left in the coke oven. Therefore, when the coal supporting plate drives the coal cakes to enter the coke oven, the coal supporting plate can extrude blocky coke, the refractory bricks at the corners of the oven wall of the coke oven can be abraded to form pits for a long time, and therefore enterprises need to fill the pits of the refractory bricks with refractory mortar.
At present, the existing method for filling the pit on the furnace wall of the coke oven adopts a long sliding plate, one end of the long sliding plate is fixed with a baffle plate, particularly refractory mortar is placed on the baffle plate, then the long sliding plate is used for driving the refractory mortar on the baffle plate to extend into the coke oven to the position of the pit on the furnace wall, and finally the long sliding plate is driven to move towards the direction of the furnace wall, and the pit is filled.
It can be understood that the method can scrape the fire clay at the pit position of the furnace wall to a certain extent, and the fire clay is controlled by the long sliding plate, so that the long sliding plate is easy to displace along the length direction of the furnace wall in the filling process, the location of the pit position of the furnace wall is inconvenient, the transverse force applied to the pit position of the furnace chamber by the fire clay is small, and the fire clay cannot be stably fixed at the pit position of the furnace wall.
