Technical Field
[0001] The utility model relates to the technical field of coke oven residual coal processing equipment, in particular to a coke oven inlet coal residual coal processing device. Background Art
[0002] Surplus coal refers to coal produced by various coals that has not been fully utilized and disposed of during the production, use, storage and sales process. At present, the coal entering the coke oven will inevitably collapse and slip during the coal loading process, resulting in the generation of accident coal, which is also a kind of surplus coal; and when the coke oven produces surplus coal, it will be transported to the inter-platform collection bucket through the scraper under the coke side platform, and then transported to the coal tower through the vertical scraper, or transported to the coke pusher or coal loading car through the scraper, and then transported to the coal yard by a forklift through the surplus coal bucket on the vehicle.
[0003] There are at least the following problems in the prior art: First, after the accident coal is produced, it not only produces dust to pollute the environment and make the working environment worse, but also increases the labor intensity of manual cleaning; second, in the process of residual coal processing, scraper machines are mostly used, but scraper machines are large in size and occupy a large area, which affects the passage of pedestrians and furnace door maintenance vehicles, and the scraper machine runs slowly, and the residual coal cannot be sent away in time, which will cause the scraper machine to get stuck and jammed, resulting in the residual coal cannot be processed; and the vertical residual coal elevator between the coal towers is long and runs slowly, which will also cause the residual coal to not be processed in time. Utility Model Content

By setting up two groups of baffle plates, the residual coal belt conveyor can be blocked and discharged from two directions. When the residual coal belt conveyor rotates forward, the residual coal collected by the residual coal collection port above one end of the residual coal belt conveyor can be discharged to the transfer belt conveyor along the corresponding baffle plate. At this time, the residual coal collection port above the other end of the residual coal belt conveyor stops discharging; when the residual coal belt conveyor reverses, the residual coal on the other end of the residual coal belt conveyor can be discharged to the transfer belt conveyor along the corresponding baffle plate. At this time, the residual coal collection port above one end of the residual coal belt conveyor stops discharging.
[0007] As an optimization, the other end of the accident coal conveyor is arranged between the residual coal collection port and the baffle plate, so that the accident coal can be transported at the same time.
[0008] As an optimization, a first closing device is provided at the discharge port of the accident coal chute, which is a closing box that matches the discharge port of the accident coal chute, and a second closing device is provided at the discharge port of the residual coal collection port, which is a closing box that matches the discharge port of the residual coal collection port. By providing the first closing device and the second closing device, a large amount of dust generated during discharge can be prevented from escaping and affecting the environment.
[0009] As an optimization, the dust suppression spray device includes a nozzle, a branch pipe and a main pipe. The nozzle is set above the other end of the accident coal belt conveyor. The water inlet of the nozzle is connected to the main pipe through a branch pipe, and a valve is provided on the branch pipe.
