A new type of energy-saving tamping coke oven coal feeding device

Abstract

The new energy-saving tamping coke oven coal charging car coal delivery device is composed of a coal bottom lifting mechanism, a hydraulic transmission mechanism, a limit mechanism, a coal bottom drag mechanism and a base, and a coal bottom lifting mechanism and a hydraulic transmission mechanism They are connected to each other, and the torque is transmitted to the lifting mechanism of the coal-supporting floor through the hydraulic transmission mechanism. The lifting mechanism deflects along the center of the load-bearing shaft. The lifting mechanism moves horizontally back and forth in the roller table groove. When the coal-supporting bottom plate is advancing or retreating, the coal-supporting bottom plate rises. When the coal charging box is ready to be loaded with coal and tamped, the coal-supporting bottom plate descends to the slideway; The lifting mechanism relies on the load-bearing shaft to connect with the load-bearing support, and the force of the supporting roller is transmitted to the load-bearing support; the load-bearing support and the hydraulic transmission mechanism are connected to the base, and the base bears the gravity and weight transmitted by the load-bearing support of the lifting mechanism for the coal bottom plate. The horizontal thrust transmitted by the hydraulic transmission rod, the transmission rod is constrained by the chain plate under the action of the hydraulic mechanism to move horizontally back and forth; the transmission mechanism of the coal support bottom plate is connected with the coal support bottom plate, and the position of the center line of the coal support bottom plate is fixed and adjusted by steel wire ropes at certain intervals The idler pulley ensures that the wire rope moves back and forth on the centerline. The invention has the advantages of rolling motion of the coal supporting bottom plate in the support roller groove, small frictional resistance, low power consumption, good coal cake stability, convenient operation and maintenance and energy saving.

Description

technical field [0001] The invention relates to a coal feeding mechanism for a tamping coke oven coal charging car or a coal charging and coke pushing integrated car. Background technique [0002] The coal feeding mechanism of the existing tamping coke oven coal loading car or the integrated coal charging and coke pushing car has a serious problem of wear and tear between the coal bottom plate and the load-bearing slideway during the sliding process, and the coal bottom plate and the slideway need to Replacement once, the replacement time is more than 10 hours, the maintenance workload is large, and the normal production of the coke oven is affected at the same time; the existing tamping coke oven coal feeding transmission device has long transmission links, heavy mechanism weight, large transmission power, and poor transmission stability And the deviation of the coal bottom plate during the sliding process. Contents of the invention [0003] In order to solve the serious...

Problems solved by technology

[0003] In order to solve the serious wear and tear of the coal bottom plate and the load-bearing slideway of the coal feeding mechanism of the existing coal charging car or the coal charging and coke pushing integrated car of the tamping coke oven, and the transmission link of the coal feeding transmission device is long, the weight of the mechanism is large, the transmission power is large, and the transmission stability is poor. In order to avoid problems such as deviation and damage to the furnace wall of the carbonization chamber when the bottom plate of the supporting coal is sliding, the present invention proposes a new type of energy-saving tamping coke oven coal feeding device
