Embodiment 1

[0025] Example 1: Three raw coal bunkers of a coal preparation plant are arranged side by side, two coal conveying belts (153 belt and 154 belt) are arranged under the raw coal bunker, and 16 coal feeding belts (No. 105-153) are arranged under each raw coal bunker Machines, that is, 8 coal feeders are arranged under each raw coal bunker corresponding to each coal conveyor belt. According to the different washing volumes of the coal preparation plant every day, it is impossible for 48 coal feeders under the raw coal bunker to be put into operation at the same time. Coal feeder start-up operation system for high-temperature coal, including: coal feeder failure status judgment module, coal feeder cumulative outage time judgment module, coal feeder start and stop judgment module, coal amount judgment module, bin position judgment module and coal feeder Accumulated running time judgment module;

[0026] The coal feeder failure state judgment module is used to judge whether the out...

Abstract

The invention discloses a coal feeder operation starting method and system for preventing high temperature of coal stored in a coal bunker. The method comprises the steps that (1) the system judges whether the total number of coal feeders in operation is larger than a system set value or not; (2) if the total number of the coal feeders in operation is not larger than the system set value, corresponding shutdown coal feeders are started according to starting conditions of the coal feeders; (3) whether accumulated operation of the coal feeders meets the system set zero clearing time or not afterthe coal feeders are started is judged; and (4) the coal feeders started to be in operation are shut down according to shutdown conditions of the coal feeder . The coal feeder operation starting system for preventing the high temperature of the coal stored in the coal bunker comprises a coal feeder fault state judgment module, a coal feeder cumulative shutdown time judgment module, a coal feederstarting and shutdown judgment module, a coal quantity judgment module, a bunker position judgment module and a coal feeder cumulative operating time judgment module. The coal feeder operation starting method and system effectively solve fire danger caused by long-time shutdown of the coal feeders.

Description

Technical field: [0001] The invention relates to a method and system for starting and operating a coal feeder, in particular to a method and a system for starting and operating a coal feeder for preventing and controlling the high temperature of coal stored in a coal bunker. Background technique: [0002] In order to ensure the full-load operation of the downstream coal washing and preparation system, the upstream coal feeding system is designed according to the full-load operation of the downstream coal washing and preparation system, including the raw coal bunker, and several coal feeders are installed under the raw coal bin along the transmission direction of the conveyor belt. According to the different washing volumes of the coal preparation plant every day, the coal washing and preparation system does not need to operate at full load in many cases. At this time, only part of the coal feeder is required to meet the needs of the downstream coal washing and preparation sys...
