The disclosed a kind of equipment for the preparation of bulky grain charcoal supported noble metal catalyst of the utility model, comprises reactor (1), is provided with agitator (3) in reactor, and agitator is connected with the motor (2) that is arranged on reactor outside; On reactor inwall, be provided with the fixed mount (4) for fixing material frame, on fixed mount, be provided with rectangle sieve aperture (5); Material frame (6) is for loading absorbent charcoal carrier, and surrounding is provided with round sieve (7), and top is provided with handle aperture (8).The utility model equipment had both retained the prototype of traditional stirring impregnating autoclave, guarantee the uniformity absorption of noble metal active component presoma on absorbent charcoal carrier, the design of material frame has effectively avoided again paddle directly to contact with absorbent charcoal carrier and the fragmentation of the activated carbon granule that causes, production efficiency is high, input cost is low, easy and simple to handle.
Description
Technical field
The novel mechanical device technical field that belongs in this area, relates to a kind of equipment for the preparation of bulky grain charcoal supported noble metal catalyst.
Background technology
The application of bulky grain charcoal supported noble metal catalyst is increasingly extensive, as medicine, hydrogenation in chemical industry, the reaction such as synthetic, this catalyst is mainly taking bulky grain shape or column-shaped active carbon as carrier, adopt infusion process that noble metal active component precursor compound is adsorbed on absorbent charcoal carrier after the method preparation of reduction.Common method has equi-volume impregnating and excessive infusion process.Equi-volume impregnating is in industrial main employing spray infusion process, conventional equipment is saturated spray dipping drum unit, this equipment is that maceration extract is constantly sprayed or sprayed on the carrier seething, liquid-solid phase is fully mixed, and maceration extract is all loaded on carrier, but this equipment requirement catalyst granules weares and teares less in the time seething, pulverization rate is low, but for graininess or column-shaped active carbon, even if there is higher mechanical strength, in the process of seething, be also difficult to Particle Breakage and the efflorescence of avoiding a large amount of.And the conventional excessive infusion process of employing, conventional equipment is impregnating autoclave, use this equipment absorbent charcoal carrier in violent stirring, also can cause a large amount of Particle Breakages and efflorescence, if do not stir, leave standstill dipping, can cause that between the catalyst granules of bed different parts, activity component load quantity is inhomogeneous, cannot ensure the uniformity of product quality.Above-mentioned two kinds of methods are all difficult to reach material and product are cleaned preferably in addition.
Utility model content
The deficiency existing for above-mentioned technology, the purpose of this utility model is to provide a kind of equipment for the preparation of bulky grain charcoal supported noble metal catalyst, this equipment investment cost is low, production efficiency is high, easy and simple to handle, this equipment can ensure that noble metal active component loads on absorbent charcoal carrier uniformly, can reduce again the degree of crushing of charcoal carrier, also can realize in-situ reducing and the cleaning of catalyst prod.
The technology that the utility model adopts is the equipment for the preparation of bulky grain charcoal supported noble metal catalyst, comprises reactor (1), is provided with agitator (3) in reactor, and agitator links with the motor (2) that is arranged on reactor outside; On reactor inwall, be provided with the fixed mount (4) for fixing material frame, on fixed mount, be provided with rectangle sieve aperture (5); Material frame (6) is for loading absorbent charcoal carrier, and surrounding is provided with round sieve (7), and top is provided with handle aperture (8).
Feature of the present utility model is also, the rectangle sieve aperture (5) arranging on the fixed mount of fixing material frame, and pore size is 170mm × 10mm, and material frame (6) circumferentially-spaced 3mm punches (7), and aperture is φ 0.5mm.
The utility model is that the material frame that absorbent charcoal carrier is housed is fixed on the fixed mount of reactor inwall, and the carrier in material frame is immersed under the liquid level of noble metal active component precursor compound, make to flow freely around the carrier of precious metal solution in material frame by stirring, active component precursor compound can be adsorbed on the surface of carrier uniformly.After upon adsorption completing, in reactor, add liquid-phase reduction agent to reduce.Then liquid in still is leached, and put into appropriate clear water catalyst is carried out to original position washing, after washing, material frame is proposed, directly put into baking oven dry.In the process of this equipment Kaolinite Preparation of Catalyst because liquid surface fluctuation is gentleer, fragmentation and the efflorescence of effectively having avoided direct mechanical to stir the absorbent charcoal carrier particle bringing.
Adopt technique scheme, the equipment tool of what the utility model provided prepare bulky grain charcoal supported noble metal catalyst has the following advantages:
1. this equipment has retained the prototype of traditional stirring impregnating autoclave, has guaranteed the uniformity absorption of noble metal active component presoma on absorbent charcoal carrier;
2. absorbent charcoal carrier is placed in material frame, has avoided the direct collision between paddle and absorbent charcoal carrier in whipping process, effectively avoided fragmentation and the efflorescence degree of particle;
3. this equipment has been realized absorption, reduction and washing integrated, and operational sequence is simple.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model is a kind of equipment for the preparation of bulky grain charcoal supported noble metal catalyst, absorbent charcoal carrier is packed in material frame (6), then this material frame is fixed on the fixed mount (4) of reactor (1) inwall, again the charcoal carrier in this material frame is immersed in below the liquid level of noble metal active component precursor compound, drive paddle (3) to stir by motor (2), make active component precursor compound solution be swirl shape disturbance, thereby drive Uniform Flow in the carrier of precious metal solution in material frame by the round sieve (7) of the rectangle sieve aperture (5) in material frame fixture and material frame surrounding, make active component precursor compound can be adsorbed on uniformly carrier surface.After upon adsorption completing, directly in reactor, add liquid-phase reduction agent to reduce, then mother liquor in still is leached, put into clear water to the washing of catalyst original position, then after material being proposed by the handle groove (8) on material frame top, directly put into baking oven dry.
