Description
Technical field
The present invention relates to a kind of process equipment of field of powder metallurgy, especially a kind of continuous dumping of novel protected atmosphere
Sintering furnace.
Background technique
Binder removal principle is to make adhesive (such as PW, CW, PP, PE under low temperature (150 DEG C -500 DEG C) and protective atmosphere
Deng) evaporation or thermally decompose to generate gas molecules (such as formaldehyde, ethylene, styrene), gas molecules by diffusion or seep
Saturating mode is transferred to forming base surface, and then adhesive, which decomposes gas and is detached into shape base surface, enters outside atmosphere, completes dumping
De- glutinous work；Sintering process principle is that injection moulding base is a porous body after de- stick, at high temperature (1100 DEG C -1500 DEG C)
Under, make to reach densification and chemical component uniformity degree because of the gap isotropism uniform shrinkage left after de- stick.
Currently, common protective agent is hydrogen (H during dumping2), the hydrogen (H of strong reducing property2) can protect and be easily oxidized
Metal powder or the metal that has been oxidized of reduction, hydrogen (H2) hydrogen atom very little, easily enter inside forming base, drive glutinous
Knot agent small molecule quickly spreads or penetrates into forming base surface, can also restore the metal being oxidized.And hydrogen (H2) no
Meeting and metal reaction.
Power transport of traditional dumping sintering furnace in furnace is using thrust type.I.e. power push-rod pushes first block of carrier
(such as sailing a boat, the object of the energy loaded material ability such as ceramic tile) straight-ahead motion, carrier push carrier (being located next between carrier),
Until furnace body exports.But because frictional force it is cumulative, carrier will receive very big thrust and first pair frictional force (contact area
Bigger, frictional force is bigger), so that carrier is easy to abrasion, fracture, deformation etc..
Traditional gas cleaning plant removes impurity using modes such as absorption, acid-base neutralization, displacements mostly, but in powder
In metallurgical metal injection molding technology, need to retain hydrogen (H2), it cannot be allowed to contact with oxygen, therefore equipment needs to seal, this
Sample just can guarantee its energy secondary use, therefore traditional gas cleaning plant should not use in this technical field.Secondly, traditional
It after gas cleaning plant enters equipment from exhaust gas, to first pass through filter and filter out particulate matter, then enter back into adsorption zone absorption
Purification.But the viscosity of paraffin, PE in impurity etc. is too high, is not easy to flow, and is easy plug filter device, should not also make in this respect
With.After-purification gas by ventilation blower be discharged into atmosphere or enter other instruments utilize.
For the continuous dumping sintering furnace of traditional stepping beam type after dumping takes off and sticks, tail gas can be discharged into combustion chambers burn, still,
Because the mobility of furnace interior is bad, often the de- glutinous impurity generated of dumping can block dumping product it is microcosmic on hole, shadow
It rings the dumping on processing original part surface and takes off glutinous and obstruction hydrogen (H2) gas enters product deep internal, wave when causing dumping de- glutinous
Take heat, the dumping time is long, low output, and yield is low.
Traditional hydrogen (H2) fire door close when only one stove door plant, lower section have a steel pipe lead to combustible gas light,
The oxygen in high-temperature region isolation air and furnace atmosphere convection current are formed at fire door.But when fire door goes out to fire fire and extinguish, lead to furnace
Door leakage, air will enter in furnace, thus cause safety accident, it is serious to make Explosion of boiler proper.
In conclusion existing technology haves the defects that the following aspects:
1, the goods support of traditional dumping sintering furnace is easily damaged, damages
Power push-rod pushes first block of carrier to do straight-ahead motion, and carrier pushes carrier (being located next between carrier), directly
It is exported to furnace body.But because frictional force it is cumulative, intermediate carrier will receive very big thrust and first pair frictional force (contacts
Area is bigger, and frictional force is bigger), so that carrier is easy to abrasion, fracture, deformation etc..
2, there are security risks for traditional dumping fire door of sintering furnace
Fire door problem is of crucial importance.Traditional fire door exit completely cuts off air using open fire mode, when fire extinguishes, fire door
Place is easy for revealing, and influences to produce, and is also easy to that safety accident occurs.
3, furnace interior atmosphere mobility is not strong, influences to generate yield
Because of the de- glutinous impurity generated of dumping, such as paraffin, (CH2O), sticky too high, the poor fluidity of PE, PP etc., is easy
It is accumulated in furnace chamber, causes some functions of equipment to be scattered and disappeared, maintenance difficult etc..And processing original part also will receive influence, make its row
The problems such as glue is de- glutinous incomplete, uneven heating.
4, hydrogen (H2) consumption it is big, endanger it is also big, cannot recycle
Open fire at fire door is using hydrogen (H2) it is used as combustion gas, hydrogen (H can be increased2) consumption；Hydrogen (H2) and oxygen
Gas Hybrid Heating, which is lighted, can occur heavy explosion, so the purified treatment of tail gas and recycling and can greatly reduce hydrogen (H2)
Consumption, improve working environment, reduce the cost of company.
In view of this, the purpose of the present invention is to provide a kind of new technical solutions to solve existing technological deficiency.
