Biofuel boiler supply isolation device

Abstract

The invention discloses a biofuel boiler supply isolation device. The biofuel boiler supply isolation device comprises a hopper and a conveying pipe, and is characterized in that the upper end of the conveying pipe is connected with a lower port of the hopper; the lower end of the conveying pipe is connected with a boiler; the cross section of the conveying pipe is rectangular; arc side walls oppositely projected outwards are respectively arranged on one set of opposite surfaces of the conveying pipe; the two arc side walls are coaxial, and are the same in diameter; the central angles of the two arc side walls are equal and bigger than 90 degrees; a shaft rod coaxial with the two arc side walls is arranged between the two arc side walls; the shaft rod is supported on the side wall of the conveying pipe through a shaft hole; the shaft rod is connected with two fan-shaped cylinders distributed in the peripheral direction at equal intervals; the central angles of the arc walls of the fan-shaped cylinders are bigger than 90 degrees; the arc walls and the arc side walls are in clearance fit; and the shaft rod is connected with a driving mechanism. The biofuel boiler supply isolation device has the effects of isolation and thermal insulation, reduces the combustion probability of fuels in the hopper, and provides more timely chances for stop maintenance.

Description

technical field [0001] The invention relates to a heating appliance using biofuel particles, in particular to a biofuel boiler feed isolation device. Background technique [0002] With the vigorous development of the economy and the progress of social production, the excessive consumption of energy has caused huge damage to the environment on which human beings depend, and it is imminent to find new clean and renewable alternative energy sources. my country is a large agricultural country, and a large amount of straw is burned in the farmland every year. In order to make rational use of energy, mechanical equipment is used to turn the straw into biofuel and press it into high-density particles, but the heat energy per unit volume is still comparable to that of coal. Fabi, when used in a boiler, needs to continuously add granular biomass fuel, and blow air into the furnace chamber to support combustion. The combustion chamber of the existing boiler is connected to a closed sil...

my country is a large agricultural country, and a large amount of straw is burned in the farmland every year. In order to make rational use of energy, mechanical equipment is used to turn the straw into biofuel and press it into high-density particles, but the heat energy per unit volume is still comparable to that of coal. Fabi, when used in a boiler, needs to continuously add granular biomass fuel, and blow air into the furnace chamber to support combustion. The combustion chamber of the existing boiler is connected to a closed silo, and the silo continues through the screw rod in the channel. Fill the combustion chamber with fuel, and the granular biomass fuel is continuously distributed in the channel. When the combustion is stopped, the fuel in the silo needs to be burned out. If the transmission stops in case of failure or special conditions, the combustion will spread to the silo and cause danger. This still needs to be solved by further innovation
