Summary:The utility model relates to a closed type rapid feeding system for a double-hearth shaft kiln. The closed type rapid feeding system comprises a two-way material distributing storage bin, two materialstoring and feeding sealing valves and two gas-material sharing reversing valves. The gas-material sharing reversing valve is composed of a reversing valve body, a two-way valve mechanism and a one-way valve mechanism. The reversing valve body is provided with a waste gas outlet, a combustion-supporting air inlet, a reversing valve feeding port and a reversing valve discharging port. A two-way valve plate of the two-way valve mechanism is used for sealing and closing the waste gas outlet or the combustion-supporting air inlet in different working states. A one-way valve plate of the one-way valve mechanism is used for sealing the reversing valve feed port; the material storing and feeding sealing valve is composed of an upper sealing valve and a lower material storing bin. On the premiseof ensuring that gas in th
