Fat section 4 end, nitric acid generating means 12 includes nitric acid holding vessel 13, nitric acid pump 14 and nitric acid effusion meter 15, the nitre being sequentially connected with
Acid is entered in Muffle passage 22 by nitric acid pump 14 and nitric acid effusion meter 15；Gas-circulating system 11 two ends respectively with defat section 4
First and end connection Muffle passage 22 forms a gas circulation channel；Muffle passage 22 is hollow cuboid, transmits guipure 23 and arranges
In Muffle passage 22 inner bottom.
As Figure 1-4, on the basis of said structure designs, metal powder injection molded continuously de-in the present embodiment
The specific works process of fat stove is as follows:
When defat work starts, first pass through heater 24 and make temperature in furnace reach about 110 DEG C, and debinding furnace
Internal Muffle passage 22 all passes through thermocouple 25 every a segment distance and controls heating-up temperature, makes skimming temp be maintained；
Shaping base material, by expecting that boat 26 carries, is transported to transmit on guipure 23 by Chain conveyer at feeding device 1, and
And enter defat preheating section 2, now, the temperature in defat preheating section 2 is about 110 DEG C, makes the shaping base material energy having just enter into fast
Speed is heated, prevents nitric acid vapor to be below deposited on part；
Material boat 26 enters back into defat section 4 after being entered burning zone 3 by defat preheating section 2, open gas-circulating system 11 simultaneously
With nitric acid generating means 12, being passed through nitrogen in gas-circulating system 11, nitric acid is entered by nitric acid pump 14 and nitric acid effusion meter 15
In Muffle passage 22, enter owing to high temperature rapidly goes to nitric acid vapor after Muffle passage 22, with equally in the entrance of defat section 4 end
The nitrogen of Muffle passage 22, according to predetermined airflow direction shuttling movement, and the direction of motion of this flow direction and material boat 26
On the contrary, nitric acid vapor can slough the binding agent shaped within base material, and the effect of nitrogen is to make Muffle passage 26 internal gas
The pure oxidation reaction that prevents, the direction of advance of material is contrary with two kinds of gas flows, it is ensured that transmit guipure 23 feeding boat 26
In shaping base fully obtain defat, defat is in hgher efficiency；
After defat reaction, nitric acid vapor the binding agent sloughed enters burner 10,10 binding agents of burner with
The form of gaseous state is burnt the most completely, reaches non-pollution discharge；
Material on material boat 26 is at defat laggard inlet/outlet double containment lock chamber 5, and outlet double containment lock chamber 5 is before material enters
Nitrogen is poured in inside, is possible to prevent the nitric acid vapor of defat section 4 end to be revealed by exporting double containment lock chamber 5, it is also possible to anti-anti-avulsion
The nitric acid vapor of fat section 4 end enters outlet double containment lock chamber 5 and is attached on material；Material boat 26 enters the closeest through Chain conveyer
Envelope conveyer belt 6, then enter sealing lock chamber 9 by Chain conveyer, by reaching to bypass conveyer belt 7 after sealing lock chamber 9, material is in bypass
Carrying out defat situation inspection on conveyer belt 7, shaping base material underproof to defat can be again by entrance transverse conveyor 8
It is re-delivered in debinding furnace carry out secondary degreasing, it is ensured that material can reach sufficient defat.This utility model is while taking off
Fat feeds, defat discharging, it is achieved continuous degreasing.
This utility model applies specific case and is set forth principle of the present utility model and embodiment, above reality
