Description
Technical field
The present invention relates to smelting equipment technical field, espespecially a kind of melting chamber with fire grate.
Background technology
In field of metallurgy, the technique that metal is very universal and important is melted, is by metal material and other auxiliary materials
Material input heating furnace dissolves and quenched, and certain physics occurs for furnace charge material in high temperature (1300~1600K) stove, chemistry becomes
Change, the pyrometallurgical processes of output crude metal or metal enrichment object and clinker.Furnace charge is in addition to concentrate, calcining, sinter etc., sometimes
It also needs to be added to the flux for making furnace charge be easy to melting, and reducing agent is added to carry out certain reaction.In addition, necessary to provide
Temperature, often need that fuel combustion is added, and be sent into air or oxygen-enriched air.Crude metal or metal enrichment object due to melting furnace
Slag mutual solubility very little and density differential are detached for two layers, and the metal after fusing can by blowing or other methods processing
Metal parts for casting various moulding.
In current metal casting, metal molten generally using top heat by the way of, the heater of top mode of heating
Top positioned at metal molten room, there is the thermals efficiency that low, molten metal heats uneven and metal for the melting chamber of this structure
The shortcomings of being easy oxidation.
Invention content
To solve the above problems, the present invention provides a kind of melting chamber with fire grate, traditional reflective heat transfer is abandoned, has been adopted
The method for penetrating and melting metal from the through-hole of fire grate with hot gas can effectively promote the thermal efficiency.
To achieve the above object, the technical solution adopted by the present invention is to provide a kind of melting chamber with fire grate, including fusing
Room ontology, the melting chamber ontology are equipped with fire grate in bottom, and the fire grate includes bottom plate and several reinforcing ribs, and the bottom plate is set
There are several through-holes, the through-hole is arranged in arrays on bottom plate, and the reinforcing rib is vertically set on bottom base plate, and is arranged
Between adjacent two row through-hole, the channel of air-flow or molten metal is formd between reinforcing rib and through-hole.
Wherein, the through-hole is round or oval through-hole.
Wherein, the melting chamber is interconnected to form by four blocks of side plates.
Wherein, the fire grate bottom is also associated with molten metal diversion trench and combustion gas enters channel.
Wherein, it is also associated with preheating device above the fire grate.
The beneficial effects of the present invention are：
Compared with traditional reflective heat transfer, the mode for being melted metal is penetrated from the through-hole of fire grate present invention employs hot gas,
The fire grate with through-hole is increased on the basis of melting chamber ontology, enters channel and metal by being connected with combustion gas in fire grate bottom
Liquid diversion trench, and it is equipped with reinforcing rib in the lower section of adjacent two row through-hole so that reinforcing rib forms air-flow or metal with through-hole
The channel of liquid so that combustion gas can go the fusing intrinsic metal of melting chamber, last molten metal that can pass through through-hole with penetrated through via holes
It is flowed into molten metal diversion trench；It is also associated with preheating device above melting chamber ontology so that the thermal efficiency can promote 15% or so.
Description of the drawings
Fig. 1 is the structure semi-cutaway of the present invention.
Fig. 2 is the structural schematic diagram of fire grate.
Drawing reference numeral explanation：1- melting chamber ontologies；2- fire grates；3- bottom plates；4- reinforcing ribs；5- through-holes.
Specific implementation mode
The present invention is described in detail with reference to specific embodiment and Figure of description.
It please refers to Fig.1 shown in -2, the present invention is about a kind of melting chamber with fire grate, including melting chamber ontology 1, the fusing
Room ontology 1 is equipped with fire grate 2 in bottom, and the fire grate 2 includes bottom plate 3 and several reinforcing ribs 4, and the bottom plate 3 is equipped with several
Through-hole 5, the through-hole 5 is arranged in arrays on bottom plate 3, and the reinforcing rib 4 is vertically set on 3 bottom of bottom plate, and is arranged in phase
Between adjacent two row through-holes 5, the channel of air-flow or molten metal is formd between reinforcing rib 4 and through-hole 5.
Compared with traditional reflective heat transfer, is penetrated from the through-hole 5 of fire grate 2 present invention employs hot gas and be melted metal
Mode increases the fire grate 2 with through-hole 5 on the basis of melting chamber ontology 1, is entered by being connected with combustion gas in 2 bottom of fire grate
Channel and molten metal diversion trench, and it is equipped with reinforcing rib 4 in the lower section of adjacent two row through-hole 5 so that reinforcing rib 4 and 5 shape of through-hole
At the channel of air-flow or molten metal so that combustion gas can go to melt the metal in melting chamber ontology 1 with penetrated through via holes 5, finally
So that molten metal can also be flowed by through-hole 5 in molten metal diversion trench, 1 top of melting chamber ontology is also associated with pre- hot charging
It sets so that the thermal efficiency can promote 15% or so.
In the present embodiment, the through-hole 5 is round or oval through-hole.
Using the above scheme, by the way that through-hole 5 is set as round or ellipse through-hole, stress is more preferable, when in use so that stove
Comb 2 is not easy to tear.
In the present embodiment, the melting chamber ontology 1 is interconnected to form by four blocks of side plates, further, the reinforcing rib 4
It is an integral molding structure with bottom plate 3, and the bottom of reinforcing rib 4 and the bottom of side plate are flush.
Using the above scheme, the bottom of reinforcing rib 4 and the bottom of side plate are flush so that the bottom of melting chamber ontology 1 is more
Add steadily, to which its normal use will not be influenced because bottom is uneven.
In the present embodiment, 2 bottom of the fire grate is also associated with molten metal diversion trench and combustion gas enters channel.
Using the above scheme so that combustion gas can penetrate the metal being melted in melting chamber ontology 1 by through-hole 5, finally
So that molten metal can also be flowed by through-hole 5 in molten metal diversion trench.
In the present embodiment, 1 top of the melting chamber ontology is also associated with preheating device.
Using the above scheme, and pre-heating system is combined, it can be the tower melting chamber exhaust temperature of tradition from 1200 degree or so
300 degree are reduced to hereinafter, promoting the thermal efficiency.
Below by specific implementation mode, the invention will be further described.
The operation principle of the present invention：Combustion gas enters channel penetrated through via holes 5 from combustion gas so that the metal in melting chamber ontology 1
Fusing, the molten metal after fusing are flowed by through-hole 5 in molten metal diversion trench, and the combustion gas after burning is upwardly into pre- hot charging
It sets, is again returned in melting chamber ontology 1 by preheating device so that the thermal efficiency can promote 15% or so.
Embodiment of above be only the preferred embodiment of the present invention is described, not to the scope of the present invention into
Row limits, under the premise of not departing from design spirit of the present invention, technical side of this field ordinary engineering and technical personnel to the present invention
The various modifications and improvement that case is made should all be fallen into the protection domain of claims of the present invention determination.
