Description
Technical field
The utility model relates to power metallurgy equipment technical field, more particularly to a kind of binder wet trap and its
System.
Background technique
In metal powder injection molded technology add binder purpose be in order to allow dry and astringent metal powder to be projected,
To produce complex-shaped workpiece, but the interim task of binder is completed after component shaping, it is necessary to it removes, to avoid
The combination and densification between powder are hindered in subsequent high temperature sintering.
At present in metal injection molded, main binder is mostly high molecule plastic such as polyethylene (PE), polypropylene (PP) etc..
Workpiece green body (processed material of degreasing process) may be collapsed, deform or be ruptured during removing binder, so degreasing
Using slow and progressive manner, first becomes formaldehyde gas with nitric acid reaction in catalysis degreasing furnace and burn, major part is viscous
Agent removing is tied, is left small part binder for workpiece green body being transported to from catalysis degreasing furnace the process of vacuum degreasing fritting furnace
Middle holding shape, does not collapse.And remaining binder is mainly high molecular polymer.
When carrying out vacuum degreasing technique, it is heated to certain temperature in furnace, the binder in workpiece green body can gasify, and be full of
In hopper.Current-carrying protective gas is filled in furnace, and hopper is connect with degreasing pipeline, and vacuum pump pumping expects furnace pressure P1 >
Pressure P2 in case, promotes gas unidirectional to flow, so that the binder steam in hopper flows into degreasing pipeline with current-carrying protective gas,
Binder steam in portion gas, which encounters inner wall of the pipe to the cold, to be become liquid and slowly flows into rouge collecting box, and liquid is not become
Binder steam continues flow through rouge collecting box (also having portion of binder steam to become liquid during this) with current-carrying gas and reaches and catch
In storage, more typical trap and its system are as shown in Figure 9 and Figure 10, and cooling water is connected in trap, separately there is multilayer fin
Binder steam is hindered, binder steam can become liquid to the cold, be tied with heater strip on trap and pipeline, prevent binder liquid
Body is solidified and is blocked, and final liquid flows into rouge collecting box.The binder steam not being captured is with current-carrying protective gas
Partially captured by inner wall of the pipe towards vacuum pump by connecting pipe, there are also fraction with current-carrying protective gas by
Pumping goes out.
But existing trap, since air velocity is too fast, portion of binder steam be easy from gap flow through without
It is captured, for the binder steam to get off that is not captured through piping, portion of binder steam can encounter inner wall of the pipe chance
Cold change liquid capture gets off, and still has fraction eventually to go in vacuum pump chamber, and pumping fluid can become after being mixed into binder
Muddiness reduces vacuum degree to influence the ability to work of vacuum pump, while also will affect the service life of vacuum pump.Usually
Pumping fluid can only constantly be replaced to solve.If normally produced by full furnace, need monthly to replace pumping fluid, cost compared with
Greatly, the cost of changing oil in a stove general ten thousand/year of 1-2,10 stoves are exactly ten thousand/year of 10-20.If client does not change oil, vacuum
Pump is easy stuck, shaft fracture when serious.
And existing trap is cold well formula trap, is connected with cooling water, fin is cascaded structure, and fin distance is smaller
(mainly catching rouge principle is to increase air-flow stroke by multilayer fin to catch rouge, and air-flow walks S type, and fin is more, and air-flow stroke is bigger,
That catches is more), in addition latus rectum very little, it is easy to appear blockage problems for existing trap.
