Description
Technical field
The present invention relates to a kind of process equipment of field of powder metallurgy, particularly a kind of continuous dumping of novel protected atmosphere
Sintering furnace.
Background technology
Binder removal principle is in low temperature（150℃-500℃）Under protective atmosphere, make adhesive（Such as PW, CW, PP, PE
Deng）Evaporate or thermally decompose to generate gas molecules（Such as formaldehyde, ethene, styrene）, gas molecules are by diffusion or ooze
Saturating mode is transferred to shaping base surface, and then adhesive decomposition gas departs from shaping base surface and enters outside atmosphere, completes dumping
De- glutinous work；Sintering process principle is that injection moulding base is a porous body after taking off and sticking, in high temperature（1100℃-1500℃）
Under, make the space isotropism uniform shrinkage because being left after de- sticking, reach densification and chemical composition uniformity degree.
At present, the protective agent commonly used during dumping is hydrogen（H2）, the hydrogen of strong reducing property（H2）Can protect and easily be oxidized
Metal dust or the metal that has been oxidized of reduction, hydrogen（H2）Hydrogen atom very little, easily enter inside shaping base, drive glutinous
Knot agent small molecule is quick to spread or penetrates into shaping base surface, can also reduce the metal being oxidized.And hydrogen（H2）No
Meeting and metal reaction.
Power transport of traditional dumping sintering furnace in stove is to use thrust type.I.e. power push-rod promotes first block of carrier
（Such as sail a boat, the object of the energy loaded material ability such as ceramic tile）Straight-ahead motion, carrier pushes carrier（It is close between carrier）,
Until body of heater outlet.But because frictional force is cumulative, carrier can be subject to very big thrust and first to frictional force（Contact area
Bigger, frictional force is bigger）, carrier is easy to wear and tear, is broken, deforms.
Traditional gas cleaning plant is used mostly the modes such as absorption, acid-base neutralization, displacement and goes the removal of impurity, but in powder
, it is necessary to retain hydrogen in metallurgical metal injection molding technology（H2）, it is impossible to allow it to be contacted with oxygen, therefore equipment needs sealing, this
Sample just can guarantee that its secondary utilization of energy, therefore traditional gas cleaning plant should not be used in this technical field.Secondly, it is traditional
Gas cleaning plant will first pass through filter and filter out particulate matter from after waste gas access arrangement, then enter back into adsorption zone absorption
Purification.But the viscosity of paraffin, PE in impurity etc. is too high, is difficult flowing, and easy plug filter device should not also make in this respect
With.After-purification gas by ventilation blower enter air or enter other instruments utilize.
After dumping takes off and sticks, tail gas can be discharged into combustion chambers burn to the continuous dumping sintering furnace of traditional stepping beam type, but,
Because the mobility of furnace interior is not good, often dumping take off glutinous generation impurity can block dumping product it is microcosmic on hole, shadow
Ring the dumping on processing original paper surface and take off glutinous and obstruction hydrogen（H2）Gas enters product deep internal, wave when causing dumping de- glutinous
Take heat, the dumping time is long, yields poorly, and yield is low.
Traditional hydrogen（H2）Only one of which stove door plant when fire door is closed, lower section has the logical combustible gas of a steel pipe to 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 combustion fire to be extinguished, cause stove
Door leakage, air will enter in stove, so as to trigger security incident, serious meeting makes Explosion of boiler proper.
In sum, there is the defect of the following aspects in existing technology：
The goods support of the 1st, traditional dumping sintering furnace is easily damaged, damages
Power push-rod promotes first block of carrier to do straight-ahead motion, and carrier pushes carrier（It is close between carrier）, until stove
Body is exported.But because frictional force is cumulative, middle carrier can be subject to very big thrust and first to frictional force（Contact area
Bigger, frictional force is bigger）, carrier is easy to wear and tear, is broken, deforms.
There is potential safety hazard in the 2nd, traditional dumping fire door of sintering furnace
Fire door problem is of crucial importance.Traditional fire door exit completely cuts off air using naked light mode, when fire extinguishes, at fire door just
Easily leakage, influence production is also easy to security incident.
3rd, furnace interior atmosphere mobility is not strong, and influence produces yield
Because dumping takes off the impurity of glutinous generation, such as paraffin,（CH2O）, PE, PP etc. sticky too high, poor fluidity, easily in stove
Accumulated in chamber, cause equipment some functions to be scattered and disappeared, maintenance difficult etc..And processing original paper can also be affected, take off its dumping
It is glutinous incomplete, the problems such as inequality of being heated.
4th, hydrogen（H2）Consumption it is big, endanger also big, it is impossible to recycle
Naked light at fire door is to use hydrogen（H2）As combustion gas, hydrogen can be increased（H2）Consumption；Hydrogen（H2）It is mixed with oxygen
Close heating to light heavy explosion can occur, so the purified treatment of tail gas can greatly reduce hydrogen with recycling（H2）Disappear
Consumption, improves working environment, reduces the cost of company.
In view of this, it is an object of the invention to provide a kind of new technical scheme solving existing technological deficiency.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention to provide a kind of continuous dumping sintering furnace of novel protected atmosphere, solution
