Abstract
The present invention discloses a mixer provided with a reflux pump, comprising: a mixer (1), a reflux pump (2), a return pipe (3), a gate valve (4), and an output pipe (5). According to the present invention, the return pipe and the reflux pump are provided at an output port of the mixer; when slurry is output, the reflux pump returns a part of the slurry, which flows through the output port, to an upper position in a cone-shaped tub of the mixer through the return pipe, and the part of the slurry is mixed again with remaining slurry in the tub and stirred. The technical scheme, according to which an enrichment phenomenon is eliminated in an outputting-while-cycling-and-mixing manner, achieves the objectives of making a denitration catalyst slurry component that is coated on a honeycomb ceramic support be even and stable.
Description
Technical field
The present invention relates to a kind of mixer, specifically referring to a kind of mixer being provided with reflux pump for being uniformly mixed denitrating catalyst slurry.
Background technology
Denitrating catalyst slurry is the catalyst for decomposing automobile exhaust on a kind of honeycomb ceramic carrier being coated in automobile exhaust purifier; The preparation of denitrating catalyst slurry and coating require fully to mix, and Local enrichment or poor phenomenon must not appear in its formula components; Prior art adopts cantilever double-spiral conical mixer to be uniformly mixed denitrating catalyst slurry, because the proportion great disparity of composition various in denitrating catalyst slurry formulations is larger, when slurry is exported by output channel, in slurry easily there is precipitation enrichment in heavy composition in the bottom of mixer, be called for short enrichment phenomenon; During practical coating is produced, enrichment phenomenon causes the slurry composition being coated in honeycomb ceramic carrier to occur sometimes enrichment and sometimes poor uneven, unstable problem, and cause the catalytic efficiency of automobile exhaust purifier product can not determine, quality is difficult to unanimously; Therefore, there are uneven, unstable problems and shortcomings in prior art.
Summary of the invention
For above-mentioned prior art Problems existing with not enough, the present invention adopts and arranges reflux line and reflux pump at the equipped at outlet port of mixer; When slurry exports, the slurry mix and blend again that the slurry that part is flow through delivery outlet by reflux pump is turned back to the top in the taper staving of mixer by reflux line and remained in bucket, by exporting while the mode of the mixing that circulates eliminates the technical scheme of enrichment phenomenon, a kind of mixer being provided with reflux pump is provided, be intended to the denitrating catalyst slurry composition making to be coated in honeycomb ceramic carrier, reach even, stable object.
The object of the present invention is achieved like this: a kind of mixer being provided with reflux pump, comprises mixer, reflux pump, reflux line, gate valve, output channel, wherein: described mixer is cantilever double-spiral conical mixer; The bottom of mixer is provided with and is called delivery outlet for slurry output channel, and the outer casing container of mixer is called taper staving;
Described reflux pump is electronic thick fluid pump;
Described reflux line is the thin-wall stainless steel matter pipeline of circular in cross-section;
Described gate valve is stainless steel gate valve;
Described output channel is the thin-wall stainless steel matter pipeline of circular in cross-section;
The lower end of reflux line is connected with the described delivery outlet of mixer and communicates, and the upper end of reflux line is connected with the top of the described taper staving of mixer, and communicates with the inside of taper staving; Reflux pump is positioned at the below of mixer and is connected in series with reflux line; Gate valve is positioned at the below of reflux line, and the upper end of gate valve is connected with described delivery outlet and communicates, and the lower end of gate valve is connected with output channel and communicates.
Operation principle and beneficial effect
When slurry exports, first open reflux pump, the slurry being positioned at described delivery outlet is carried out circulation through reflux line pump to the top of described taper staving mix, afterwards, open gate valve again and export slurry through output channel, now, the slurry mix and blend again that the slurry that part is flow through delivery outlet by reflux pump is turned back to the top in the taper staving of mixer by reflux line and remained in taper staving, eliminates enrichment phenomenon by the mode exporting the mixing that circulates.
This apparatus structure is simple, and reliable operation, effectively eliminates the enrichment phenomenon of denitrating catalyst slurry, causes the denitrating catalyst slurry composition being coated in honeycomb ceramic carrier even and stable, the catalytic efficiency of automobile exhaust purifier product is determined and uniform quality.
Above-mentioned, the present invention adopts and arranges reflux line and reflux pump at the equipped at outlet port of mixer; When slurry exports, the slurry that part is flow through delivery outlet by reflux pump turns back to the top in the taper staving of mixer by reflux line, with the slurry remained in bucket mix and blend again; By exporting while the mode of the mixing that circulates eliminates the technical scheme of enrichment phenomenon, overcome prior art and there are uneven, unstable problems and shortcomings, a kind of mixer being provided with reflux pump provided, makes the denitrating catalyst slurry composition being coated in honeycomb ceramic carrier reach even, stable object.
