Description

Technical Field

[0001] The utility model relates to the technical field of weight hammer valves, in particular to a high-sensitivity weight hammer valve feeding structure. Background Art

[0002] The 2×65 hole 6m ramming coke oven project of Shougang Changgang Coking Plant was completed and put into operation in 2016. It is equipped with a ground dust removal station on the machine side, which is responsible for the purification of smoke and flue gas at the furnace door of the coal loading / pushing machine side. A set of dust collecting hoods is installed on the upper part of the furnace door on the machine side corresponding to each carbonization chamber for the effective collection of furnace head smoke. At the same time, a heavy hammer valve type conveying main pipe is arranged on the furnace top on the machine side for the transportation of furnace door smoke. A small dust collection hood is set above each furnace door, and the pipeline is opened and closed by the lifting of the heavy hammer valve. The opening and closing mechanism of the heavy hammer valve is set on the smoke guide car. Before ramming coal loading, the device on the smoke guide car will lift the heavy hammer valve corresponding to the coal loading, and send the raw coal gas generated at the furnace door during the coal loading process into the conveying pipeline. Through the suction of the fan of the machine side ground station, it first enters the flame arrester, then enters the coke particle adsorption device, and finally enters the bag dust collector for purification.

[0003] During the long-term operation, it was found that the heavy hammer valve had a fall chain connected to the heavy hammer valve. During the falling process, due to mechanical vibration and other reasons, the valve valve was displaced, the seal was not tight and raw gas leaked, causing raw gas and flue gas to escape from the burner head. A heavy hammer valve limit device was needed.

[0004] During the opening and closing process of the original weight valve, there was no restriction on the closing position when the weight valve fell, resulting in the valve falling position sometimes deviating. The valve was not tightly sealed, which would cause the escape of flue gas and waste gas, causing certain impacts on environmental protection management. Utility Model Content
