Description
Technical field
The present invention relates to field of metallurgy, and in particular to a kind of metallurgical furnace.
Background technique
Metallurgy is exactly that metal or metallic compound are extracted from ore, and metal, which is made, with various processing methods has centainly
The process and technique of the metal material of performance.The method multiplicity of metallurgy, wherein traditional metallurgical method is exactly pyrometallurgy, pyrogenic process
Metallurgy is the metallurgical process carried out under the high temperature conditions.Mineral pass through a system at high temperature some or all of in ore or concentrate
Column physicochemical change generates the compound or simple substance of another form, is enriched in gas respectively, in liquid or solid product,
Achieve the purpose that the metal to be extracted is separated with gangue and other impurity.Thermal energy needed for realizing pyrometallurgical processes, usually
It is supplied by fuel combustion, pyrometallurgy includes: the processes such as drying, calcination, roasting, melting, refining, distillation, in pyrogenic process smelting
During gold, redox reaction occurs for ore and raw material, and obtained metal is fused into molten condition, and impurity forms waste residue,
Then molten metal is isolated, bulk gas can be generated while metallurgy.
Current metallurgical furnace top discharge mouth is respectively positioned on metallurgical furnace lower part, and miscellaneous from discharge port discharge in order to avoid giving up, therefore goes out
With a certain distance from material mouth has from bottom for metallurgical vessel, it is now placed in the molten metal below discharge port and is difficult to be discharged from discharge port, metallurgical furnace
Inside still remaining large quantitative metal liquid can not be discharged, it is difficult to completely separate molten metal with waste residue, cause the waste of molten metal.Its
Secondary, clinker and the ore being put into metallurgical furnace are easy to fall on around discharge port, block discharge port, molten metal is difficult to smooth row at this time
Out.In addition, waste residue is solid, when waste residue is discharged, waste residue is difficult to actively drop out from slag-drip opening, needs to manually take out at this time useless
Slag, but due to the temperature of smelting apparatus height, worker is easy to be burned.
Summary of the invention
The purpose of the present invention is to provide a kind of remaining metallurgical furnaces of reduction molten metal.
In order to achieve the above objectives, the technical scheme is that it is a kind of reduce furnace inner metal liquid remnants metallurgical furnace, including
Rack and the furnace body being fixed on the rack, are fixed with heating room in furnace body, and heating room side wall is equipped with into fuel port, fixed in furnace body
There are baffle, heating room side wall and baffle that the cavity of furnace body is divided into heating chamber and outflow chamber, baffle bottom and heating ceiling portion
Between formed connection heating chamber and flow out chamber channel；The piston that can be slided along sidewall of the furnace body is equipped in heating chamber, piston will add
Hot chamber is divided into the heating zone of top and the compressional zone of lower section, is equipped with both ends in compressional zone and is separately fixed at bottom of furnace body and piston
On upper ejector sleeve, upper ejector sleeve is scalable, and the air pump that inlet end is connected to heating chamber is fixed in rack, and the outlet side of air pump is fixed
There is exhaust pipe, exhaust pipe is connected to far from air pump one end with upper ejector sleeve, and exhaust pipe is equipped with closed exhaust outlet；In heating chamber
Portion is equipped with closed feed inlet and slag-drip opening；It flows out chamber side wall and is equipped with discharge port, discharge port is not higher than channel.
When metallurgical, heating interior first is added from fuel port in fuel, fuel generates amount of heat in heating Indoor Combustion,
Heating chamber and outflow chamber are heated.Then the raw materials such as ore are added in heating chamber from feed inlet, ore is in gravity
Under drop down on piston.The metal molten to react in ore is at molten condition, in the process chemically reacted
Middle generation bulk gas.In fusion process, the molten metal in heating zone is continuously increased, when molten metal liquid level is higher than channel,
Molten metal is intracavitary from channel inflow and outflow.After metal molten, waste residue is remained on piston.
Air pump is opened, air pump extracts the gas of generation out, and gas enters in upper ejector sleeve from exhaust pipe, the air pressure in upper ejector sleeve
Increase, upper ejector sleeve elongation, piston upward sliding, while the waste residue fallen on piston being pushed up.In the process, molten metal
Also it is pushed up by piston, while the height of molten metal liquid level increases, it is intracavitary that molten metal from channel flows to outflow, then from discharge port
Discharge.After the completion of metallurgy, taken out from slag-drip opening by the waste residue on piston is located at, and open exhaust outlet, the gas in exhaust pipe from
Exhaust outlet discharge, piston set back.
This programme has the beneficial effect that (one) ore chemically reacts during heating, generates gas, waste residue and gold
Belong to, metal molten is molten metal, and gas is pumped into upper ejector sleeve by air pump, at this time piston upward sliding, by waste residue and molten metal
It pushing up, the liquid level of molten metal increases, and raised molten metal enters outflow chamber from channel, then it is discharged from discharge port, therefore can
To reduce the remnants of furnace body inner metal liquid.
(2) when starting metallurgy, the ore of addition is fallen directly on above piston, the waste residue position that ore and metallurgy generate at this time
It is intracavitary without falling on outflow from channel in compressional zone, therefore waste residue will not block discharge port, molten metal can be smooth from discharging
Mouth discharge.And due to forming channel between baffle and heating room, channel and non-porous form at this time, therefore waste residue and ore will not block
Channel, it is intracavitary that molten metal smooth can flow to outflow.
(3) heating chamber and outflow chamber can be heated simultaneously when heating indoor fuel combustion, can be avoided enter into
Flow out intracavitary molten metal solidification.
(4) baffle can play barrier effect to ore and waste residue, avoid ore and waste residue fall on outflow it is intracavitary, then
Ore and waste residue is avoided to block discharge port.
