Background
With the sustainable development of the country, the country pays more and more attention to the comprehensive utilization of resources. A certain amount of low-quality coal can be mixed in the tamping coking coal blending to replace high-quality coal for coking, so that the tamping coal coking cost is low, and the quality of coke can be improved under the condition of the same coal blending. Tamping coke oven machinery is currently the mainstream product of domestic coking equipment.
The shaking feeder in the tamping coke oven equipment is a key equipment, and has the main functions of sending coal in a coal tower of an oven body into a vehicle-mounted coal box of a tamping coal charging car through a feeding groove device of the shaking feeder, tamping bulk coal into coal cakes with certain rigidity through a tamping machine, and finally sending the formed coal cakes into a carbonization chamber of the oven body for high-temperature carbonization to form coke. The coal charging mode of the tamping coke oven belongs to the side coal charging technology, and the following problems are caused in the process that coal materials are fed into a vehicle-mounted coal box through a shaking feeder: 1. the blanking of the furnace body coal tower is uneven, so that the height of coal in the vehicle-mounted coal box is low, and the control is difficult; 2. the furnace body coal tower feed opening blocks up easily, discovers untimely, leads to in the tamping hammer pole directly falls into the coal bunker, the damage tamping hammer pole. The blanking condition is observed only by tamping workers at present, but the feeding uniformity condition cannot be mastered. The control of the feeder feed rate of the shake feeder is an important factor affecting the stability of the tamped coal cake.
At the present stage, no technology is available for detecting the operation failure of the shaking feeder.
SUMMERY OF THE UTILITY MODEL
