Description
Technical field
The present invention relates to purifying vehicle exhaust field, specifically automotive catgalyst slurry processing method.
Background technology
Existing catalyst is by cellular ceramics or metallic carrier and is attached to supported catalyst coating and forms.Urge
Agent coating is generally by the oxide material with large specific surface area（Such as aluminum oxide）, hydrogen-storing material and be dispersed in oxide or
The noble metal active component on hydrogen-storing material surface（Often it is Pt（Platinum）、Pd（Palladium）、Rh（Rhodium）In one or more）Composition.Its
In hydrogen-storing material be generally the composite oxides containing cerium zirconium, it is by the oxygen in adsorption storage tail gas or discharges oxygen to adjust
The ratio of oxidizing component and reproducibility component in tail gas, while making carbon monoxide and oxidized hydrocarbon oxygen, nitrogen oxygen
Compound is reduced.Current three-way catalyst generally all uses double coating structures, in coating because slurry attachment is uneven,
Cause the clean-up effect of catalyst unsatisfactory.
The content of the invention
For above-mentioned technical problem, the present invention, which provides one kind, can make slurry adhere to more uniform automotive catgalyst slurry
Processing method.
Technical scheme is used by the present invention solves above-mentioned technical problem：Automotive catgalyst slurry processing method, bag
Include following steps：
（1）Automotive catgalyst composite powder material is configured to slurry with deionized water；
（2）Pretreated hollow column like catalyst carrier is set in outside cylinder, drives carrier to immerse in above-mentioned slurry by cylinder；
（3）After slurry is fully supported on carrier, mobile cylinder simultaneously drives carrier to remove slurry；
（4）Slurry unnecessary in carrier duct is thrown away by rotating the cylinder；
（5）Reclaim the slurry thrown away.
Preferably, the composite powder material and deionized water are delivered in size barrel respectively is stirred mixing.
Preferably, the cylinder bottom is provided with the agitating paddle that mixing is stirred to slurry.
Preferably, it is provided with the support chip for supporting the carrier on the upside of the agitating paddle on the cylinder.
Preferably, it is provided with several pieces micro-blades, the carrier set on the upside of the support chip on the cylinder
Blade outboard is located at, is thrown away slurry unnecessary in carrier duct with wind-force caused by movable vane piece rotation by cylinder.
Preferably, the stop block for preventing carrier from rotating is provided with the support chip.
As can be known from the above technical solutions, the present invention is arranged hollow carrier on the outside of cylinder, drives carrier to soak by cylinder
Enter in slurry, after the completion of coating, wind-force caused by the micro-blade that is rotated on cylinder throws away slurry unnecessary in carrier duct.
It follows that the present invention is outwards thrown away the slurry in duct from carrier inside using centrifugal force, wind-force can be avoided to blow to carrier
Outer surface, so as to ensure the uniformity of carrier outer surface coating.
Embodiment
The present invention is described in detail below, illustrative examples of the invention and explanation are used for explaining the present invention herein, but
It is not as a limitation of the invention.
Automotive catgalyst slurry processing method, comprises the following steps：
First, automotive catgalyst composite powder material is configured to slurry with deionized water；The composite powder material and go
Ionized water is delivered in size barrel respectively is stirred mixing, mixes material mixing, in implementation process, the cylinder bottom
The agitating paddle that mixing is stirred to slurry is provided with, is advantageous to conveniently stir.
At the same time, hollow column like catalyst carrier need to be pre-processed, to facilitate load coating, then by hollow column
Carrier is set in outside cylinder, drives carrier to immerse in above-mentioned slurry by cylinder；The present invention, which is arranged on the cylinder, is located at institute
State the support chip on the upside of agitating paddle and on the one hand can support carrier, on the other hand can prevent carrier from being contacted with agitating paddle, avoid stirring
The rotation damage carrier of oar.
After slurry is fully supported on carrier, mobile cylinder simultaneously drives carrier to remove slurry so that loads cated load
Body departs from size barrel, then throws away slurry unnecessary in carrier duct by rotating the cylinder；The present invention is in the cylinder
Upper to be provided with several pieces micro-blades on the upside of the support chip, the carrier is set in blade outboard, passes through cylinder band movable vane
Wind-force caused by piece rotation throws away slurry unnecessary in carrier duct, thereby guarantees that the coating uniform of carrier.In implementation process
In, the stop block for preventing carrier from rotating is provided with the support chip, carrier can be avoided to get rid of the coating on its surface because of rotation
Fall.After slurry unnecessary in duct is thrown away, because carrier is departing from size barrel, therefore the slurry thrown away can enter into size barrel
Row recovery, does not pollute the environment not only, and cost-effective.
Above-mentioned embodiment is used for illustrative purposes only, and is not limitation of the present invention, relevant technical field
Those of ordinary skill, can be so that various changes can be made and modification without departing from the spirit and scope of the present invention, therefore institute
There is equivalent technical scheme also to belong to scope of the invention.
