Abstract

The invention relates to a coal supply tamping device of a side-mounted coke oven, comprising a coal-discharge circuit and a tamping circuit. The coal-discharge circuit and the tamping circuit comprise switches, contactors, relays and motors, each switch, each contactor and each relay are connected in series and connected with a motor in parallel, and the branches are connected with a power supply in parallel. The coal-discharge circuit and the tamping circuit are simple power supply circuits and are respectively connected with the power supply for work, and coal-discharge and tamping work can be automatically finished by switching on the circuits and starting the motors; a relay in the coal-discharge circuit and the tamping circuit can automatically switch off when a current in a circuit is over heavy so as to protect the motor from being damaged. In addition, the coal-discharge circuit and the tamping circuit can also be combined with a PLC to realize the integrated automatic control of coal discharge and tamping to free workers from watchful operation so as to greatly lighten the labor intensity and improve the coal cake quality and the production efficiency.

Description

technical field [0001] The invention relates to a coal feeding and tamping device, in particular to a coal feeding and tamping device for a side-loaded coal coke oven, especially an 18-hammer tamping machine for automatic tamping and 9 feeding machines for coal feeding. Background technique [0002] Tamping briquettes is an important part of the production process of side-loading coal coke ovens. Poor tamping quality of briquettes will cause briquettes to collapse, which not only affects the production cycle, but also brings a huge workload to cleaning. Once collapsed, cleaning up is laborious and time-consuming. Secondly, the quality of briquettes also directly affects the quality of coke, so all coking enterprises attach great importance to the use effect of the tamping machine. The feeding and coal discharge need to work in coordination with the tamping machine, and they are linked together. Only when the coal is placed and tamped is well coordinated, can high-quality b...
