Embodiment Construction

[0012] Combine below figure 1 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0013] A kind of equipment that prepares the slurry for automobile catalyst, comprises slurry bucket 1, and described slurry bucket side is provided with the bracket 2 that can move up and down, and this bracket is installed with can move up and down with this bracket and can extend into slurry. The column body 3 in the barrel can be sleeved with an automobile catalyst carrier 4, and a motor 5 driving the rotation of the column body is installed on the support. The lifting and lowering of the support can be realized by air cylinders, hydraulic cylinders, etc. During the implementation process, the catalyst composite powder material for automobiles is prepared into a slurry with deionized water, and the composite powder material and deion...

Abstract

The invention relates to the field of automobile tail gas purification, in particular to a device for preparing slurry for automobile catalysts, comprising a slurry tank, one side of the slurry tank is provided with a bracket that can move up and down, and the bracket is equipped with a The support moves up and down and can extend into the column in the slurry tank, the column can be sleeved with an automobile catalyst carrier, and a motor that drives the column to rotate is installed on the support. In the present invention, a hollow carrier is sheathed on the outside of the column, and the carrier is driven by the column to immerse in the slurry. After the coating is completed, the wind force generated by the rotating micro-blades on the column will throw out the excess slurry in the channel of the carrier. It can be seen that the present invention uses centrifugal force to throw the slurry in the channel from the inside of the carrier to the outside, which can prevent the wind from blowing to the outer surface of the carrier, thereby ensuring the uniformity of the coating on the outer surface of the carrier.

Description

technical field [0001] The invention relates to the field of automobile tail gas purification, in particular to equipment for preparing slurry for automobile catalysts. Background technique [0002] The existing catalyst consists of a honeycomb ceramic or metal carrier and a catalyst coating attached to the carrier. The catalyst coating is usually composed of an oxide material with a large specific surface area (such as alumina), an oxygen storage material, and a noble metal active component (usually Pt (platinum), Pd (palladium) dispersed on the surface of the oxide or oxygen storage material. , Rh (rhodium) in one or more) composition. The oxygen storage material is generally a composite oxide containing cerium and zirconium, which adjusts the ratio of oxidizing components and reducing components in the tail gas by absorbing and storing oxygen in the tail gas or releasing oxygen, so that carbon monoxide and hydrocarbon oxygen While being oxidized, nitrogen oxides are red...
