Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 to 6, the embodiment of the present invention provides a mixing device for mixing fluids, in particular, the fluids are mainly liquids. The mixing device includes a mixing container 10, an extraction assembly 20, and an injection assembly 30, and an inlet portion of the extraction assembly 20 communicates with the mixing container 10 to extract liquid within the mixing container 10 through the extraction assembly 20. The inlet part of the injection assembly 30 is communicated with the outlet part of the extraction assembly 20, and the outlet part of the injection assembly 30 is communicated with the mixing container 10, so that the liquid extracted by the extraction assembly 20 enters the injection assembly 30, and the fluid is injected into the mixing container 10 through the injection assembly 30 at a preset pressure, so that the circular mixing is realized, the liquid is fully mixed, and the uniformity of the liquid mixed with the liquid is improved.

Wherein, injection subassembly 30 includes first injection unit, and first injection unit includes first injection part 31 and second injection part 32, and first injection part 31 and second injection part 32 set up relatively, and first injection part 31 is located the top of second injection part 32. The outlet end of the first spraying part 31 is obliquely disposed toward a direction away from the second spraying part 32, and the outlet end of the second spraying part 32 is obliquely disposed toward a direction away from the first spraying part 31 to mix the fluid in the first preset mixing direction by the first spraying unit. Specifically, the first preset mixing direction may be a clockwise direction or a counterclockwise direction.

With such a configuration, since the first spraying part 31 and the second spraying part 32 are oppositely arranged, a vortex-like effect is formed inside the mixing container 10 under the action of the liquid at the outlet end of the first spraying part 31 and the liquid at the outlet end of the second spraying part 32, so that the liquids of different types can be sufficiently mixed under the action of force. Meanwhile, as the first spraying part 31 is positioned above the second spraying part 32, the liquids with different heights in the mixing container 10 can be mixed sufficiently, and the situation of layering among the liquids with different heights is avoided, so that the uniformity of liquid mixing is improved better. Therefore, through the technical scheme provided by the embodiment, the technical problem of poor liquid mixing uniformity in the prior art can be solved.

Meanwhile, the mixing device in the embodiment is simple in structure, convenient to manufacture and achieve, free of special customization, and good in mixing speed block and mixing uniformity.

Specifically, the mixing container 10 in this embodiment may have a stirring barrel structure, the cross section of the stirring barrel is circular, and the extending direction of the stirring barrel is a direction perpendicular to the cross section of the stirring barrel. The height direction of the increase in this embodiment is the extending direction of the mixing drum.

In the present embodiment, the first injection part 31 includes a first horizontal connection pipe 311 and a first outlet pipe 312, the first horizontal connection pipe 311 is communicated with the first outlet pipe 312, the first outlet pipe 312 is disposed obliquely downward at a first predetermined angle with respect to the first horizontal connection pipe 311, and the first outlet pipe 312 is disposed at a second predetermined angle with respect to the vertical direction and extends toward a direction away from the second injection part 32. Specifically, when the direction of the liquid ejected from the first ejection part 31 and the direction of the liquid ejected from the second ejection part 32 are both horizontal, only the uniformity of the local liquid in the mixing container 10 is affected, and no vortex occurs, and no movement of the liquid in a wide range occurs to perform uniform mixing. By adopting the structure, the liquid in the mixing container 10 can be driven to move better by the liquid at the spraying position, so that the full mixing is realized, and the condition of uneven mixing is avoided. Meanwhile, compared with the arrangement mode that the first outlet pipe 312 is inclined upwards, the arrangement mode that the first outlet pipe 312 is inclined downwards can better guide the liquid flow inside, so that the liquid in the container can be mixed fully. Especially, when the liquid in the mixing container 10 is not filled up to a level lower than the first spraying part 31, the first outlet pipe 312 is inclined upward to allow a part of the liquid to be directly sprayed on the wall surface of the upper part of the container and flow down from the wall surface, which does not effectively move the liquid in the container, and thus does not facilitate the uniformity of the liquid in the container.

Specifically, the first predetermined angle may be 135 °, and the first horizontal connection pipe 311 and the first outlet pipe 312 are connected in a circular transition manner. The second predetermined angle can be adjusted and set adaptively according to the height of the specific mixing tank and the height of the liquid. Specifically, can increase driving motor, driving motor drives first injection portion 31 and rotationally sets up to according to the direction of actual conditions second predetermined angle, so that make the inside liquid of mixing vessel 10 realize the vortex better and mix, thereby improve the homogeneity that the liquid mixes better.

Specifically, the structure of the second injection part 32 in the present embodiment is the same as that of the first injection part 31, and the deflection angle of the first injection part 31 may be the same as or different from that of the second injection part 32. Specifically, the second predetermined angle in the present embodiment is the same as the angle at which the second jetting part 32 is obliquely disposed in the direction away from the first jetting part 31, so as to improve symmetry and facilitate formation of a vortex.

Specifically, in order to further improve the mixing uniformity, the first spraying units can be a plurality of, and the plurality of first spraying units are arranged at intervals along the height direction of the mixing container 10, so that the mixing of the liquid in the mixing container 10 can be better realized, and the uniformity of the liquid mixing can be improved.

Specifically, the second preset mixing direction is opposite to the first preset mixing direction, and when the first preset mixing direction is a clockwise direction, the second preset mixing direction is an anticlockwise direction; when the first preset mixing direction is the counterclockwise direction, the second preset mixing direction is the clockwise direction. In a specific using process, the first spraying unit and the second spraying unit can act alternately, namely, the liquid in the mixing container 10 can rotate forwards and backwards, and under the combined action of the forward rotation and the backward rotation, the liquid in the mixing container 10 can be further and fully mixed, so that the mixing uniformity of the liquid is further improved.

Specifically, the structures of the third ejection part 33 and the fourth ejection part 34 in the present embodiment may be the same as the structure of the first ejection part 31. Thus, the production and manufacture can be facilitated. The first ejection portion 31, the second ejection portion 32, the third ejection portion 33, and the fourth ejection portion 34 are different mainly in the position of arrangement, the size of the angle, and the deviation direction.
