Circulating reflux agitating device
Technical field
This utility model belongs to technical field of chemical, particularly relates to a kind of circulating reflux agitating device.
Background technology
Powdered graphite metal clad material has the structure of uniqueness and numerous unusual physicochemical properties, demonstrates huge potential using value in many science and technology field, is increasingly becoming a study hotspot of concern both at home and abroad in recent years.
In powdered graphite metallic cover preparation process, small-size effect, quantum size effect, interface and skin effect and macro quanta tunnel effect due to powdered graphite, powdered graphite is made to be susceptible to reunite with in liquid medium in atmosphere, if it not being carried out dispersion process, then largely effect on properties of product.In prior art, dispersion is stirred by the mode of conventional machinery stirring, but mechanical agitation form is single, can not meet the requirement of powder dispersity.
Utility model content
The purpose of this utility model is to overcome prior art to there is the defect that mechanical agitation can not meet the requirement of powder dispersity, it is provided that a kind of circulating reflux agitating device.
This utility model solves its technical problem and be the technical scheme is that a kind of circulating reflux agitating device, including kettle, mechanical stirring device and membrane pump, described mechanical stirring device is arranged in described kettle, described autoclave body bottom is tapered, described autoclave body bottom is provided centrally with circulation interface, in described kettle, upper end is provided with atomizer, and described atomizer height is higher than dispersion liquid level in kettle, and described circulation interface and atomizer are connected by membrane pump.
Further, described mechanical stirring device includes shaft and two stirring paddles, and two described stirring paddles are separately mounted on the differing heights position of shaft.Two the most different stirring paddles are utilized effectively to be stirred by the material of differing heights in kettle so that powder material is dispersed.
As preferably, for making the material of circulating reflux can be dispersed to kettle, described atomizer quantity be two, and is symmetricly set on the upper end of kettle.
Beneficial effect: utilize membrane pump to realize the circulating reflux of dispersion in kettle in the application, and by atomizer, the material of circulation is uniformly sprayed in the dispersion in kettle so that dispersion disperses evenly;It addition, autoclave body bottom to be arranged to taper, and loop structure is arranged on the center of autoclave body bottom, it is to avoid autoclave body bottom powder material is reunited the problem of deposition so that dispersing uniformity is more preferable.

Detailed description of the invention
Embodiment
As shown in Figure 1, a kind of circulating reflux agitating device, including kettle 1, mechanical stirring device and membrane pump 4, described mechanical stirring device is arranged in described kettle 1, bottom described kettle 1 tapered, described kettle 1 bottom centre is provided with circulation interface 11, and in described kettle 1, upper end is symmetrically arranged with two atomizers 5, described atomizer 5 height is connected by membrane pump 4 higher than dispersion liquid level in kettle 1, described circulation interface 11 and atomizer 5.
Specifically, described mechanical stirring device includes that shaft 2 and two stirring paddles 3, two described stirring paddles 3 are separately mounted on the differing heights position of shaft 2.
Operation principle is as follows: in kettle 1, dispersion disperses under the effect of mechanical stirring device, membrane pump 4 works simultaneously, dispersion in kettle 1 is pumped to atomizer 5 by circulation interface 11, and by atomizer 5 again by its atomized spray dispersion in kettle 1, so circulate.
Should be appreciated that specific embodiment described above is only used for explaining this utility model, be not used to limit this utility model.Obviously changed by what spirit of the present utility model extended out or changed among still in protection domain of the present utility model.
