Description

A kind of novel energy-conserving controllable type continuous melting coke-fired furnace

Technical field

The utility model relates to a kind of novel energy-conserving controllable type continuous melting coke-fired furnace, and it is applicable to low melting point non-ferrous alloys such as melting aluminium, aluminium alloy, kirsite.

Background technology

The melting furnace of domestic various non-ferrous alloy foundry enterprises and alloy pig manufacturing enterprise employing at present all is traditional coke-fired furnace, this coke-fired furnace mostly contains the body of heater that a steel construction shell and refractory material are built into, its inside coke of packing into, put on the coke crucible is arranged, put into solid metallic in the crucible, the heat that utilizes combustion of coke to produce makes the solid metallic fusing.The defective of this coke-fired furnace has: needs to use crucible, and the one, many one deck consumption, moreover its prune job is wasted time and energy not only dirty but also tired; Melting efficiency is low, and the heat transmission of traditional coke-fired furnace is mainly carried out with conduction pattern, because conduction of velocity is slower, so its energy waste is serious and burn-off rate is very slow, energy utilization rate is less than 10%; To the poor controllability of conditions such as fusion temperature, time, particularly more difficult control when the molten metal temperature in the crucible is too high; Production process is discontinuous, can only be that unit carries out intermittent operation with the crucible, and it is essential with many stove relay operations to boost productivity, and this must cause the significant wastage of spatial area and human resources.

Summary of the invention

The purpose of this utility model will provide a kind of without crucible, energy-conservation and melting efficiency is high, controllability good, can conveniently carry out quantity-produced novel energy-conserving controllable type continuous melting coke-fired furnace exactly.

The technical solution of the utility model is, novel energy-conserving controllable type continuous melting coke-fired furnace, the body of heater that it contains the steel construction shell and is built into refractory material, its feature: in described body of heater, be aligned in sequence with coke combustion chamber, non-ferrous metal melting chamber and molten metal moist closet; Being situated between between described coke combustion chamber and non-ferrous metal melting chamber is provided with first passage, and then being situated between between described non-ferrous metal melting chamber and molten metal moist closet is provided with second channel; In addition, on the coke combustion chamber, be provided with openable combustion chamber lid; On the non-ferrous metal melting chamber, be provided with openable fusing chamber cap, on the molten metal moist closet, be provided with openable insulation chamber cap.

During concrete enforcement, other controllable type air blast and the temperature control device of also being provided with in the coke combustion chamber then has narrow and small exhaust emissions passage at insulation chamber cap edge.

Because the utility model is without crucible, it has not only saved the expense of a purchase crucible, has also saved the trouble operation of cleaning crucible; Because the utility model carries out with conduction, radiation and three kinds of modes of convection current in the heat transmission simultaneously, so its energy utilization rate can reach 30%; The utility model is by air blast flame and heat to be delivered to the non-ferrous metal melting chamber through first passage, enter the molten metal moist closet through second channel again, therefore can realize by control, thereby can guarantee the good quality of product the molten metal temperature controlling to air blast; Owing to the possibility of throwing in coke and solid metallic in respective compartments has continuously become reality, only also can realize fully with a stove realization quantity-produced imagination.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Among the figure, the 1-body of heater, 2-coke combustion chamber, the 3-combustion chamber lid, the 4-first passage, 5-non-ferrous metal melting chamber, 6-melts chamber cap, the 7-second channel, 8-molten metal moist closet, 9-is incubated chamber cap, 10-exhaust emissions passage.

The specific embodiment

With reference to accompanying drawing.The utility model has a steel construction shell and with the body of heater 1 that refractory material is built into, is aligned in sequence with coke combustion chamber 2, non-ferrous metal melting chamber 5 and molten metal moist closet 8 in body of heater 1; Between coke combustion chamber 2 and non-ferrous metal melting chamber 5, be provided with the first passage 4 that is used to transmit flame and heat, between non-ferrous metal melting chamber 5 and molten metal moist closet 8, be provided with the second channel 7 that is used to transmit flame and heat again; For the needs of continuous operation, on coke combustion chamber 2, be provided with openable combustion chamber lid 3, on non-ferrous metal melting chamber 5, be provided with openable fusing chamber cap 6, on molten metal moist closet 8, then be provided with openable insulation chamber cap 9.

Thereby coke combustion chamber 2 is to throw in coke to make its burning produce the inner chamber of heat, can open combustion chamber lid 3 when needing and add coke inward; Non-ferrous metal melting chamber 5 is the places that hold solid metallic and make its fusing, can open fusing chamber cap 6 when needing and add solid metallic inward; Molten metal moist closet 8 then is to be used to hold molten metal and it is carried out degasification refining slag hitting, and takes out qualified molten metal casting ingot-forming or be used for Foundry Production.Thereby the oxygen continuous burning that the coke that the coke combustion chamber is 2 li is sent here by air blast produces a large amount of flames and heat, flame and heat enter non-ferrous metal melting chamber 5 through first passage 4 under the effect of air blast, solid metallic fusing in the non-ferrous metal melting chamber 5, molten metal, heat and flame enter molten metal moist closet 8 through second channel 7 again, and molten metal continues to obtain heating therein to reach temperature required.Last tail gas is then opened narrow and small exhaust emissions path 10 from insulation chamber cap 9 edges and is overflowed.

Compare with traditional coke-fired furnace, the utlity model has following advantage: 1, no crucible, both saved like this Buying the expense of crucible, needn't carry out again the cleaning brushing of crucible, is economical again laborsaving really; 2, energy-conservation, The melting efficiency height, on probation showing is because heat transfer has conduction, radiation, three kinds of modes of convection current, so energy The utilization rate in source is three times of original stove, and the non-ferrous metal melting amount of unit interval is equivalent to three, four Platform tradition coke-fired furnace; 3, controllability is strong, can realize by the control to air blast the control to the molten metal temperature System, thus significantly improve product quality; 4, continuous production is strong, because can be by continuous adding coke and solid The attitude metal, thus reach continuous melting, produce the purpose of molten metal continuously, accomplish not only to save manpower, but also Save plant area.

A bit need in addition explanation, being exactly the utility model fuel used can be coke, also can be other Suitable fuel.
