Intelligent ash removal device and method for filtering tank of single crystal furnace

The invention discloses an intelligent ash removal device and method for a single crystal furnace filtering tank, and relates to the field of photovoltaic technology, the intelligent ash removal device comprises a temperature measuring device and an intelligent ash removal system; the intelligent ash removal system comprises a first/second signal control cabinet and a hinge motion cylinder, the hinge motion cylinder comprises a flexible chain, a top purging port, a lower purging port and a bottom slow oxidation port in the filtering tank are equipped with slow oxidation valves, and an ash conveying port is equipped with an electromagnetic valve. According to the device, the flexible chain is used for stirring the accumulated dust to be matched with multidirectional air inlet, so that silicon monoxide is fully oxidized, the phenomenon that a filter cloth bag is burnt due to sudden temperature rise caused by direct contact with air due to insufficient oxidation is reduced, the temperature measuring device monit
