In the coke oven production process, the oven protection iron is required to protect the coke oven body to prevent the deformation of the oven body from affecting the service life of the coke oven, wherein the oven door is the most important device in the coke oven protection iron system. In each coking period, the coke oven door is taken off and hung once, the coke pusher (or the coke guide) is taken off from the oven door frame before pushing the coke, and the oven door is hung on the oven door frame again after the coke pushing is finished. The coke oven door not only plays a role in protecting the oven body, but also plays a role in sealing, namely preventing raw gas in the oven from leaking.
When the tamping coke oven is used for charging coal, firstly, coal dust is tamped into coal cakes outside the oven by a tamping coal charging integrated machine at the machine side, and then the tamping coal cakes are sent into a carbonization chamber by a coal supporting plate of the tamping coal charging integrated machine. The main problems of the traditional tamping coke oven side door are: when the tamping coke oven is used for charging coal, due to the reasons of time limitation, coke quality and the like, the coal cake made of the coal dust cannot be very firm, part of crushed coal falls off in the process of feeding the coal cake into the carbonization chamber, the crushed coal is accumulated below the coke side oven door or is extruded into a gap between the oven door and the oven door frame, so that the coke side oven door is repeatedly extruded and deformed, the sealing surface of the knife edge of the coke side oven door is separated from the oven door frame, raw coke gas leaks and even fires, the knife edge of the coke side oven must be replaced after burning out, normal production of the coke oven is affected, the labor maintenance cost and the equipment investment are increased, and environmental pollution is caused by the leakage of the raw coke gas.

The vertical surface of one side of the castable block bracket far away from the coke side furnace door body consists of a lower straight section and an upper inclined section, wherein the top surface of the lower straight section is Gao Yutuo in the height of the top surface of the coal plate, and the height difference is not less than 11mm; the inclination angle of the upper inclined section is not less than 28 degrees; the thickness of the lowest layer castable block is adapted to the inner width of the castable block bracket corresponding to the lower straight section.
The bottom of the castable block bracket is provided with a plurality of vertical anchoring holes, and the castable block bracket is connected with the lowest layer castable block in an anchoring way through vertical anchoring pieces; a plurality of horizontal anchoring holes are formed in one side, close to the coke side furnace door body, of the castable block bracket, one end of each horizontal anchoring piece is sleeved on each vertical anchoring piece, and the other end of each horizontal anchoring piece sequentially penetrates through the castable block, the castable block bracket and the coke side furnace door body to realize anchoring connection.
Compared with the prior art, the invention has the beneficial effects that:
the furnace door pouring material block bracket adopts a pin-tilting structure, so that enough space is reserved between the pouring material block bracket and a furnace door frame to contain crushed coal falling from a coal cake (only the crushed coal is required to be cleaned regularly), the furnace door cannot deform due to long-term extrusion by external force, the furnace door is ensured to maintain good sealing performance for a long time, the environment pollution caused by leakage of raw coke oven gas is prevented, the manual maintenance cost is reduced, and the normal production of a coke oven and the investment of equipment are facilitated to be maintained.
