Problems solved by technology

The prior art biomass fuel aluminum melting furnace, for example, the publication number is CN103471389A, and the name is a Chinese patent application for a biomass fuel melting aluminum furnace. The biomass fuel aluminum melting furnace includes a furnace body and a crucible, and the furnace body is provided with a heating The crucible is placed in the heating chamber, and there is a support block for supporting the crucible at the bottom of the heating chamber. The heating chamber and the combustion chamber are connected through the flame inlet; After reaching the crucible, most of the flame rises directly and is discharged from the smoke outlet, which reduces the contact area with the flame when the crucible is heated, making the heating speed of the crucible slower and the heating efficiency lower; at the same time, the flame comes out of the flame inlet directly If it is sprayed on the area of ​​the crucible facing the flame inlet, the temperature in this area will rise faster, and the crucible will be prone to cracking due to uneven heating, resulting in a shorter service life of the crucible; After coming out, it is directly sprayed on the area of ​​the crucible facing the flame passage, while other areas of the crucible have less contact with the flame, which makes the heat exchange efficiency between the flame and the crucible lower, resulting in greater fuel consumption and energy consumption. The temperature of the crucible The fluctuation is also large, the stability is poor, and the production cost of molten aluminum is also increased

Abstract

A biomass fuel aluminum melting furnace comprises a furnace body (1), a crucible (2), an air inlet (3) and a feeding pipe (4). A cavity is arranged in the furnace body (1) and is formed by separating the furnace body (1) through a refractory brick layer (5). A smoke channel (1.3) and a gas inlet channel (1.4) are arranged in the space between the refractory brick layer (5) and the inner wall of the furnace body (1) and is formed by separating the furnace body (1) through a heat-conducting material layer (13), wherein the inlet and the outlet of the smoke channel (1.3) are located at the two ends of a C-shaped structure respectively, the inlet and the outlet of the gas inlet channel (1.4) are also located at the two ends of the C-shaped structure respectively, the inlet of the gas inlet channel (1.4) is communicated with the air inlet (3), and the outlet of the gas inlet channel (1.4) is communicated with an ash chamber (1.2). One end of the feeding pipe (4) is located in a combustion chamber (1.1), and the other end of the feeding pipe (4) is located outside the furnace body (1). Compared with the prior art, the biomass fuel aluminum melting furnace has the advantage that the crucible is capable of being evenly heated, long in service life, high in heat exchange efficiency, low in energy consumption, good in use stability and low in aluminum melting production cost.

Description

technical field [0001] The invention relates to a biomass fuel aluminum melting furnace. Background technique [0002] Biomass fuel aluminum melting furnace refers to an aluminum melting furnace that is heated by burning solid biomass fuel. The prior art biomass fuel aluminum melting furnace, for example, the publication number is CN103471389A, and the name is a Chinese patent application for a biomass fuel melting aluminum furnace. The biomass fuel aluminum melting furnace includes a furnace body and a crucible, and the furnace body is provided with a heating The crucible is placed in the heating chamber, and there is a support block for supporting the crucible at the bottom of the heating chamber. The heating chamber and the combustion chamber are connected through the flame inlet; After reaching the crucible, most of the flame rises directly and is discharged from the smoke outlet, which reduces the contact area with the flame when the crucible is heated, making the heat...
