Biomass fuel aluminum melting furnace

Abstract

The invention discloses a biomass fuel aluminum melting furnace. The biomass fuel aluminum melting furnace comprises a furnace body (1), a screw feeding machine (2) and a chimney (3). The furnace body is composed of a combustion chamber, a heating chamber and a crucible, and the crucible is arranged inside the heating chamber; a flame baffle layer and a hot air duct are arranged between the furnace wall of the heating chamber and the crucible; the chimney is communicated with the heating chamber; the fuel chute of the screw feeding machine is communicated with the combustion chamber. when the biomass fuel aluminum melting furnace works, solid biomass fuel is pushed into the combustion chamber by the screw feeding machine for combustion, flame generated through the combustion enters the heating chamber through a flame vent and heats the crucible around the outer wall of the crucible front bottom to top through the hot air vent under the action of the flame baffle layer, and smoke is exhausted to the atmosphere through the chimney. According to the technical scheme of the biomass fuel aluminum melting furnace, through the flow retarding function of the flame baffle layer, heat exchange is enhanced, temperature dissipation of the heating chamber is retarded and the aluminum alloy melting temperature inside the crucible can be maintained, accordingly, the biomass fuel aluminum melting furnace can achieve the objects of energy consumption reduction and cost saving.

Description

technical field [0001] The invention relates to an aluminum melting furnace, in particular to a biomass fuel aluminum melting furnace which burns biomass fuel to heat and melt aluminum alloy from a solid state to a liquid state. Background technique [0002] Aluminum melting furnaces are usually furnaces heated by burning fossil fuels, such as coke furnaces, oil furnaces, or furnaces heated by electricity, such as electric melting furnaces. Aluminum melting furnaces heated by burning solid biomass fuels are called biomass fuel aluminum melting furnaces , the prior art biomass fuel aluminum melting furnace follows the structure of the coke furnace, and has poor thermal insulation performance. In addition, the biomass fuel burns rapidly and lacks continuous embers heat. A large amount of heat is lost through the flue to maintain the melting temperature of the aluminum alloy in the crucible. Insufficient capacity, in order to maintain the temperature in the furnace, the feeding...

[0002] Aluminum melting furnaces are usually furnaces heated by burning fossil fuels, such as coke furnaces, oil furnaces, or furnaces heated by electricity, such as electric melting furnaces. Aluminum melting furnaces heated by burning solid biomass fuels are called biomass fuel aluminum melting furnaces , the prior art biomass fuel aluminum melting furnace follows the structure of the coke furnace, and has poor thermal insulation performance. In addition, the biomass fuel burns rapidly and lacks continuous embers heat. A large amount of heat is lost through the flue to maintain the melting temperature of the aluminum alloy in the crucible. Insufficient capacity, in order to maintain the temperature in the furnace, the feeding material must be continuously burned, resulting in large fuel consumption and high cost of melting aluminum. Therefore, the existing technology has the problems and deficiencies of large energy consumption and high cost
