Abstract
The utility model discloses a compound charging device for wet process of preparing nanometer powder. The utility model comprises a feeding pipe, at least one rotatable injector connected with the feeding pipe, the feeding pipe and the rotatable injector are connected via a ring charging reflux pipe. Nanometer powder or predecessor body produced by the utility model has even and fine granularity and fine dispersibility, eliminates birdnesting, prevents from agglomeration. The utility model guarantees stable product quality in mass production. The utility model has a scientific and rational design, simple structure and convenient control and adjustment.
Description
Technical field
The utility model relates to the device for preparing nano-powder, is fit to the synthetic feeding device that all wet chemistry legal systems are equipped with nano material.
Background technology
Nano-powder is widely used in every field such as petrochemical industry, pottery, weaving, environmental protection because granularity is little, surface area is big thereby have excellent specific properties such as dimensional effect, skin effect and electron tunneling effect, is changing people's the life and the industrial structure.
But at present owing to feed way and device imperfection, problems such as the speed of wayward reaction, acid-base value, it is inhomogeneous that the nano-powder of producing still exists granule size, and difficult quality reaches requirement; Occur phenomenons such as hard aggregation, caking when producing simultaneously, mass production is restricted.
The patent No. is that the utility model of ZL00223535.8 discloses a kind of device for preparing nanometer zinc oxide precursor, comprising a branch feed cavity and hybrid chamber two shower nozzle partly.This shower nozzle makes charging be multi-stage spray, reaches the nucleation of crystal and the inhibition of growth conditions, realizes the balance of thermodynamics quasistatic process, makes product more tiny.But because shower nozzle is fixed, can not change the feeding point, the limitation of feedstock direction makes charging inequality in the reaction vessel, and the nano-powder that is produced is still even inadequately.
The utility model content
The purpose of this utility model is to provide a kind of wet method to prepare the synthetic feeding device of nano-powder, improved existing feeding device shortcoming improperly, can adjust the feeding point at any time, can realize better that mass transfer, heat transfer and reaction speed are controlled, guarantee that nano-powder or presoma have more even tiny granularity and more uniform dispersiveness.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: this wet method prepares the synthetic feeding device of nano-powder, comprises feed pipe, and at least one rotation sprayer communicates with described feed pipe.
It is conical, spherical or tubaeform that described shower nozzle can be.
Can be connected by the reinforced return pipe of annular between described feed pipe and the rotation sprayer.
Compared with prior art, the utility model is owing to adopted rotatable shower nozzle, can change the direction of shower nozzle as required arbitrarily, reactant can join in the reaction vessel by the rotating sprinkler site-directed quantitative, can control the nucleation of crystal and growth conditions, the speed of growth well, make particle size even, controlled, and realize that mass transfer, heat transfer and reaction speed are controlled, guaranteed that nano-powder or presoma have evenly tiny granularity and good dispersion.Between feed pipe and rotation sprayer, set up the reinforced return pipe of annular, and a plurality of rotation sprayers evenly are set on annular charge pipe, make the more even dispersion of spray of raw material, eliminate and reunite, prevent caking, when producing in enormous quantities, guaranteed constant product quality, epigranular, good dispersion.This feeding device design science is reasonable, simple structure, control and easy to adjust.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described specifically.
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
This feeding device is installed in the top of reaction vessel.As shown in Figure 1 and Figure 2, feed pipe 1 is connected with the reinforced return pipe 2 of polygonal or annular, is evenly distributed with the shower nozzle that can rotate in any direction 3 that a plurality of and reinforced return pipe communicates on reinforced return pipe 2.The shape of rotation sprayer 3 can be cone shape, the spherical crown bodily form or tubaeform etc., is provided with a plurality of uniform discharge openings 4 at the bottom surface of cone or ball-crown body, the exit face of loudspeaker.Described rotation sprayer can be hinged on the reinforced return pipe of annular, can the rotation of manual or electronic control shower nozzle on all directions.
