Summary of the invention
The purpose of this utility model is in order to solve existing metallurgical powder drying device in the course of the work, when long-time high temperature ingress of air or steam, top layer oxidation is serious, affect the problem of powder characteristic, provide a kind of reasonable in design, the anti-oxidation powder de-watering apparatus efficiently quick, disposal ability is large.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of anti-oxidation powder de-watering apparatus, comprise the little housing in two broad in the middle being formed by two Rotary-tables, it is characterized in that the described horizontal middle part of housing is provided with the rotating shaft that can make housing rotate along its axis, housing is provided with high temperature nitrogen mouthpiece, argon gas mouthpiece, is also provided with the exhausting window that powder metallurgy porous material is made on housing.
The housing that bicone merges not only has stronger structural strength, completes the powder product of larger process amount, and utilizes " conical hopper " powder delivery easy.Housing, in the course of work of rotation, utilizes the inert atmosphere of high temperature drying equably powder to be heated, and powder is prolonging housing internal cone wall and rolling, and is fully washed in the nitrogen of temperature flowing.Gas fluidity is strong, and environmental pressure is stable, can in time the steam producing in inner chamber system be taken out of to anti-oxidation powder.In addition, because the uniformity of ambiance, powder is heated also more even, does not have " sending out burnt " phenomenon producing because of hot-spot in traditional drying unit.Exhausting window adopts powder metallurgy porous material to make, and powder metallurgy porous material claims again porous sintered material, is made up through moulding, sintering of spherical or erose metal or alloy powder; Material internal duct is crisscross, interpenetrate, and generally has 30%～60% volume porosity, and its aperture and porosity all can be controlled, and permeability function is good, and high-and low-temperature resistance, anti-thermal shock, and gas easily sees through but powder or dust are difficult for filtering.
As preferably, described high temperature nitrogen mouthpiece is connected with feeder by pipeline, and described feeder and housing connect as one.When work, feeder and housing rotate simultaneously, to ensure providing mobility nitrogen incessantly in housing.
As preferably, the two ends of described housing are respectively equipped with valve.The valve at two ends uses as charging, discharging opening, and when work, sealing is closed.
As preferably, described high temperature nitrogen mouthpiece is provided with several, is arranged on two Rotary-tables of composition housing.Multiple high temperature nitrogen mouthpieces can ensure that enclosure interior is full of nitrogen, makes internal pressure uniform and stable fast.
As preferably, described argon gas mouthpiece position is provided with valve.Before housing rotation, be filled with argon gas, then use valve closing.
As preferably, described exhausting window position is provided with check valve.As the exhausting window of the use of gas and liquid filtering, can be arranged to various structures form, discharge in order to make internal gas carry moisture content, and prevent that extraneous air from entering, and establishes check valve.
As preferably, the Rotary-table major diameter position of described composition housing is provided with the cylinder that diameter equates with major diameter, and the end of rotating shaft is fixed on cylinder.This device can design the volume of the more than 10 tons treating capacity of disposable processing, between rotating shaft and housing, must have enough bonding strengths.
As preferably, described feeder is provided with gas pressurizer.Ensure in the course of the work the harmony of enclosure interior pressure.
Effective effect of the present utility model is: can realize automation mechanized operation, water evaporates is discharged fully, makes powder obtain higher aridity, and non-oxidation successful, has avoided inner hot-spot and produces and send out phenomenon burnt.
