High-temperature shaft kiln sealing energy-saving device for magnesium-iron-calcium sand calcination

The high-temperature shaft kiln sealing energy-saving device comprises a base, a shaft kiln body is fixedly installed on the left side of the top of the base, a feeding pipe is arranged on the top of the shaft kiln body, a feeding hopper is fixedly installed on the top of the feeding pipe, a first box body is fixedly installed at the middle end of the top of the base, and a second box body is fixedly installed at the middle end of the top of the first box body. And a first fan is fixedly mounted on the left side of the top of the first box body. Flue gas is conveyed into the inner cavity of the first box body through the input end of the first fan via the exhaust pipe and the feeding pipe, particles in the flue gas can be filtered by arranging the punching net plate, the filtered flue gas enters the inner cavity of the second box body through the connecting pipe, and the particles in the flue gas can be filtered by arranging the HEPA filter screen and the activated carbon filter screen. And the input end of a
