Abstract

The utility model discloses a novel biomass crucible oven, which belongs to the field of biomass crucible ovens. The novel biomass crucible oven comprises an oven body, a combustion chamber, a crucible and a chimney, wherein the crucible is positioned above the combustion chamber; a crucible base for supporting the crucible is fixed below the crucible; the chimney is arranged on one side of the top end of the oven body, and is communicated with the combustion chamber; and light clay bricks, expansion perlite, ceramic fiber mats and clay bricks are arranged in sequence between the oven body and the combustion chamber from outside to inside. Through the way, the problems of incapability of fully utilizing flue gas exhausted by the conventional crucible oven, high dust content of flue gas, environmental pollution, poor heat-insulating effect and the like can be solved; and the novel biomass crucible oven has the advantages of good heat-insulating effect, low energy consumption, energy saving and environmental friendliness.

Description

A kind of novel biomass crucible furnace

Technical field

The utility model relates to the crucible furnace field, particularly relates to a kind of novel biomass crucible furnace.

Background technology

Crucible furnace is the equipment of metallurgy industry deposite metal commonly used, be a kind of stove for metals such as fusing or Insulating aluminium, copper, lead, generally comprise: body of heater, burner, burner hearth, put into the crucible of burner hearth and the chimney of the toxic emission after the burning to atmosphere.During work, burner combustion provides thermal source to burner hearth, crucible is heated, the heating in, the high-temperature flue gas of generation from the smoke stack emission to the atmosphere in.

The crucible furnace that sell in the market and factory uses; generally adopt with coke; diesel oil or gas burner system are as the crucible furnace of the energy; but these crucible furnaces of the prior art; not only pernicious gas content is more in the flue gas that produces during heating crucible; a large amount of high-temp waste gas are discharged in the atmosphere under unemployed state; energy-output ratio is larger; the high-temp waste gas of its discharge has increased the weight of again the burden of environment; and; existing crucible furnace general block outside the combustion chamber has light fire brick, but effect of heat insulation also is not fine, causes thermal loss in the combustion chamber; be unfavorable for environmental protection, be unfavorable for building energy-conservation; environmental protection; conservation-minded society.

The utility model content

The technical problem that the utility model mainly solves provides a kind of novel biomass crucible furnace, the problem such as can solve that the fume afterheat that existing crucible furnace discharges can not take full advantage of, large, the contaminated environment of dust in the flue gas, effect of heat insulation are poor.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of novel biomass crucible furnace is provided, comprise: body of heater, combustion chamber, crucible and chimney, described crucible is positioned at directly over the combustion chamber, be fixed with the crucible seat stand of support crucible under the described crucible, described chimney is arranged on body of heater top one side and communicates with the combustion chamber, is disposed with from outside to inside light weight fireclay brick, expanded perlite, ceramic fiber blanket and clay brick between described body of heater and combustion chamber.

In preferred embodiment of the utility model, described chimney lower end is connected with return duct, and described return duct is terminal to communicate with the combustion chamber.

In preferred embodiment of the utility model, described chimney exhaust outlet below is provided with screen pack.

In preferred embodiment of the utility model, described Inner Wall of Combustion Chamber is provided with automatic ignitor.

The beneficial effects of the utility model are: the utility model adds multilayer insulation outside the combustion chamber, has strengthened the effect of heat insulation of combustion chamber, avoids because of heat loss too much in the combustion chamber, causes the burning indoor temperature to reduce, thereby affects the efficiency of heating surface of crucible furnace; In chimney, add screen pack, the solid particle in the flue gas is filtered, reduced the pollution of flue gas to environment; Add return duct under chimney, the waste heat in the flue gas of discharging is carried out recycling, do not cause the loss of energy, energy-saving effect is better.
