Abstract
The utility model discloses an energy-saving annealing stove which is used for producing a malleable cast iron. The front lower part of the stove body is provided with a combustion chamber. The combustion chamber and the stove body belong to integration. The utility model comprises a dust washing port, a closing plate, a combustion supporting air blowing port, a carbon charging port and a grate bar. A lower coal injecting port is arranged on the upper part of the grate bar, and the grate bar is arranged slantingly in the combustion chamber and the inclined angle is 5-6 DEG. The utility model has the advantages of small occupation area, high thermal efficiency, equalized temperature in the stove, high product annealed quality, low coal consumption, light environment pollution, etc.
Description
The utility model relates to a kind of annealing energy-saving furnace of malleable iron production usefulness, belongs to the malleable iron Equipment for Heating Processing.
At present, the malleable iron melting of China mostly is cupola furnace, and the thermal treatment of malleable iron is many again to be fuel with the coal.Because the unstable and the heat treatment technics poor performance of cupola melting, the thermal treatment level is lower.Mainly have: heat treated product loss is bigger, and mechanical performance of products is not high, and energy consumption is many, and coal can not fully burn, annealing cost height, deficiency in economic performance, shortcoming such as production efficiency is low, and environmental pollution is serious, and labour intensity is big.
The purpose of this utility model is to provide a kind of good heat insulating in order to overcome above-mentioned the deficiencies in the prior art part, the thermo-efficiency height, has a narrow range of temperature, saves the energy, the little annealing energy-saving furnace of environmental pollution.
The purpose of this utility model is achieved in that the utility model comprises furnace foundation, shaft, furnace roof, chimney.The all around of shaft, the position is provided with a plurality of thermometer holes and vision slit up and down, and is provided with the side floss hole, and last pci port is positioned at the upside of body of heater, and the bottom of last pci port is the burning platform.The shaft forward lower part is provided with a combustion chamber and following pci port, and combustion chamber and shaft are one.Constitute by ash removing hole, closure plate, combustion-supporting blowing mouth, coal filling hole, fire bars, in order to make coal dust firing abundant, the utility model is provided with down pci port, following pci port is positioned at the top of fire bars, and fire bars is positioned at the top of combustion-supporting blowing mouth, and combustion-supporting blowing mouth is arranged on the side of body of heater, the top of closure plate, charcoal-adding opening is positioned at the opposite of combustion-supporting blowing mouth, and ash removing hole is arranged on the top of closure plate, and closure plate is positioned at the upper end of furnace foundation.The burning platform on shaft top is provided with a grade brick.Furnace roof is smeared with straw cob crust and is obturaged.
The purpose of this utility model can also reach by following measure: fire bars of the present utility model adopts metallic substance, tilts to be placed in the combustion chamber, and the angle of inclination is 5-7 °.In order to make temperature equilibrium in the stove, set shelves brick on the burning platform of the present utility model can be placed arbitrarily with temperature in the stove.
Compared to existing technology, it is little, simple in structure, easy to make to the utlity model has floor space, quick heating, temperature equalisation in the good heat insulation, body of heater, product annealing quality height, coal consumption is low, the thermo-efficiency height, the production efficiency height, advantage such as labour intensity is low, and environmental pollution is light, and wearing quality is good.
The explanation of accompanying drawing drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model charcoal-adding opening position view.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
Fig. 1, ash removing hole (1), closure plate (2), combustion-supporting blowing mouth (3), fire bars (4), following spout (5), combustion chamber (6), crosswind hole (7), last pci port (8), burning platform (9), furnace roof (10), common brick (11), refractory fibre (12), refractory brick (13), shelves brick (14), side floss hole (15), charcoal-adding opening (16), ash removing hole (1) is opened the top in closure plate (2), closure plate (2) adopts the iron plate of thick 10mm, be placed on the upper end of furnace foundation, the bottom of ash removing hole (1), combustion-supporting blowing mouth (3) is opened the side at body of heater, the size of mouth is 130mm * 130mm, fire bars (4) is a ferrous products, tilt to be placed in the combustion chamber (6), the angle of inclination optimum value is 5.7 °.It is top that following pci port (5) is opened at fire bars (4), apart from fire bars (4) 200-250mm, burning platform (9) is positioned at the below of the last pci port (8) of shaft, in order in time to adjust the temperature at each position in the stove, one grade of brick (14) is put on the top of burning platform (9), and the placement angle of shelves bricks (14) can be adjusted arbitrarily.The high 115mm of shelves brick.The thick 300-500mm of furnace roof of the present utility model (10) adopts a heatable brick bed base soil to mix the straw grass and closes mud and smear envelope.Its insulation plasticity is good,
