Automatic flushing device in dewatering belt conveyor cofferdam

The utility model relates to the technical field of belt conveyor cleaning equipment, in particular to an automatic flushing device in a dewatering belt conveyor cofferdam, which comprises a flushing water tank, a flushing water pump and a flushing mechanism. The flushing water tank is communicated with the flushing mechanism, and the flushing water pump is arranged on a pipeline between the flushing water tank and the flushing mechanism; the flushing mechanism is arranged around the vacuum belt dehydrator in a surrounding manner; a plurality of nozzles are formed in the flushing mechanism, and the arrangement density of the nozzles is gradually reduced from the driving end of the vacuum belt dehydrator to the driven end of the vacuum belt dehydrator. According to the cleaning device, the cleaning effect in the cofferdam of the dewatering belt conveyor can be remarkably improved, the cofferdam is kept clean, the possibility that the filter cloth deviates or is torn due to gypsum accumulation is reduced to the
