Problems solved by technology

Existing biomass aluminum melting furnaces generally use a single-crucible heating method, which consumes high energy consumption during use, and the crucible scoops up more aluminum slag from the aluminum mouth, which affects product quality; when the feed head is added to the crucible and cold aluminum ingots, the The temperature changes greatly, which may lead to the solidification of aluminum water in severe cases; in addition, part of the ash mixed with flue gas from biomass fuel enters the aluminum liquid, resulting in an increase in the carbon content of the aluminum liquid. Increased use costs; some factories that manually operate aluminum ladle, because the high temperature is directly at the position of the ladle water mouth, the ambient temperature is too high during work, which increases the difficulty of operation for workers

Abstract

The invention discloses a biomass double-crucible aluminum melting furnace which comprises a biomass fuel bin and an air blower; a discharging port of the biomass fuel bin is communicated with a feeding port of a biomass combustion chamber through a feeding auger and a blanking pipe; an air outlet of the air blower is communicated with an air inlet of the biomass combustion chamber through a waste heat recovery cavity and a combustion air supply duct in sequence; a fire outlet of the biomass combustion chamber is communicated with a fire inlet of a melting crucible heating channel through a fire channel; a melting crucible is arranged at the center of the melting crucible heating channel and is communicated with a liquid aluminum using crucible through a liquid aluminum chute; the liquid aluminum using crucible is arranged at the center of a heat preservation crucible heating channel; a fire inlet of the heat preservation crucible heating channel is communicated with a fire outlet of the melting crucible heating channel through a flue gas channel; a flue gas port of the heat preservation crucible heating channel is communicated with a chimney. The biomass double-crucible aluminum melting furnace disclosed by the invention has the beneficial effects that the liquid aluminum temperature is stable, the use environment is improved, the heat preservation is performed by fully utilizing flue gas waste heat, and an energy-saving effect is achieved.

Description

technical field [0001] The invention relates to an aluminum melting furnace, in particular to a biomass double crucible aluminum melting furnace. Background technique [0002] With the continuous support, promotion and development of the national slogan of energy conservation and emission reduction, coal, as a fuel that pollutes the air, has been gradually replaced by biomass pellet fuel or natural gas, but natural gas has the disadvantage of high cost. It cannot be fully applied to all small and medium-sized enterprises. [0003] Compared with coal and natural gas, the use cost of biomass pellet fuel is between the two, and is much lower than natural gas, and biomass pellet fuel has the characteristics of extremely low content of harmful gas components and less harmful gas emissions during combustion. And the ash after combustion can also be used directly as waste; due to the characteristics of biomass pellet fuel, the structural design of the melting furnace is gradually ...
