Description
Technical field
The present invention relates to technical field of engineering machinery, more particularly, to a kind of powder selection device and three-dimensional sand stone equipment processed.
Background technology
Due to the increasingly scarcity of natural sand resource, the industrial structure becomes industry to mechanism sandstone adjustment and reform, mechanism sandstone
The Main way of development.Natural sand resource increasingly depleted, country is also increasingly stricter to the protection of natural sand resource, on the contrary, city
The fast-developing demand again accelerating the raw materials such as sandstone of city's construction.On the other hand, high, big etc. the feature of modern building with
And the raising to shockproof requirement, the quality of engineered building materials, energy-saving and environmental protection are required to significantly improve, particularly some countries
Major project, such as：The requirement to sandstone for the engineering such as bridge, tunnel, highway, light rail subway is very strict, and sky
So the quality of sandstone is unstable, and clay content is more to build needs it is impossible to meet.Therefore, mechanism sandstone replacement natural sand stone becomes
Inexorable trend for concrete-containing building material market development.And three-dimensional sand line floor space processed is little, energy consumption is low, increasingly for market institute
Accreditation.
The existing screening to Machine-made Sand is mainly realized by vibrosieve, taking single-deck screen as a example, as shown in figure 1, building stones
Vibrosieve is entered by entrance a1, by screen cloth, small powder is passed through small powder delivery outlet a2 and exports, Fructus Anisi Stellati passes through Fructus Anisi Stellati delivery outlet a3
Dust in the process, is suctioned out from dust removal port a4 by output using cleaner unit.
Existing powder selection device is typically more complicated to the structure realizing the proportioning deriving material, and above-mentioned vibrosieve is in sieve
During point material, be rolled in dust due to building stones together with, only lean on cleaner unit to be difficult to eliminate the dust of the inside and stone powder.Finally sift out
The finished product material material of output (small powder delivery outlet a2) also need to enter powder concentrator and carry out after-treatment, and the powder concentrator on market
Floor space is big, high energy consumption.It is therefore desirable to design a kind of powder selection device and the building stones entering vibrosieve being carried out dedusting and remove
Powder is from carrying out after-treatment without entering back into powder concentrator.

Specific embodiment
Below by drawings and Examples, technical scheme is described in further detail.
The specific embodiment of the present invention be for the ease of to the design of the present invention, solved technical problem, constitute skill
The technical characteristic of art scheme and the technique effect bringing have further description.It should be noted that for these embodiment party
Formula illustrate not constitute limitation of the invention.Additionally, the technical characteristic being related in following embodiments of the present invention is only
The conflict of not constituting each other just can be mutually combined.
In one schematic embodiment of powder selection device of the present invention, as shown in Fig. 2 powder selection device, it includes selecting powder case
Body, selects the upper and lower of powder casing side to be respectively equipped with feeding mouth 1 and first material outlet 3, selects under powder casing opposite side
Portion is provided with second material outlet 4, selects powder casing to be provided with for communicating with aerator between feeding mouth 1 and first material outlet 3
Air-supply entrance 2, at least partly big particle diameter material in the material to be selected sent into by feeding mouth 1 under gravity can be from
One material outlet 3 is derived, and remaining material to be selected can be blown to choosing in aerator from the wind-force effect that air-supply entrance 2 is sent into
The opposite side of powder casing, is provided with baffle assembly between first material outlet 3 and second material outlet 4, baffle assembly can move
To change the displacement size in first material outlet 3 for the big particle diameter material.
In this schematic embodiment, by setting air-supply entrance 2 between feeding mouth 1 and first material outlet 3, and
Baffle assembly is set between first material outlet 3 and second material outlet 4, because the quality of big particle diameter material is larger, by entering
At least partly big particle diameter material in the material to be selected that material mouth 1 is sent into can be derived from first material outlet 3 under gravity,
And remaining material to be selected aerator can be blown to from the wind-force effect that air-supply entrance 2 is sent into select the opposite side of powder casing with
For subsequent treatment, baffle assembly can move with the displacement size changing big particle diameter material in first material outlet 3, Yi Jigai
Become ratio in remaining material to be selected for the big particle diameter material, not only achieve dedusting, and also achieve stock grading, structure letter
Single, there is higher exploitativeness.Due to baffle assembly be used for change big particle diameter material first material outlet 3 discharge capacity and its
Remaining material to be selected accounts for major part it is preferable that as shown in Fig. 2 the bore of first material outlet 3 is less than second material outlet 4
Bore, is so easy to adjust, convenient and swift.
Wherein, as shown in Fig. 2 in figure rectangle symbols represents big particle diameter material, circular hollow symbol zero represents small particle
Material, solid stain●Represent dust.It should be noted that big particle diameter material and small particle material are simply comparatively, that is, exist
Material in a larger preset range for the particle diameter is big particle diameter material, and the material that particle diameter is less than this preset range is granule
Footpath material, those skilled in the art can determine this preset range according to practical situation.
As a kind of preferred implementation of baffle assembly, in a preferred embodiment, as shown in Fig. 2 dividing plate group
Part includes with respect to the determine dividing plate 31 selecting powder casing to be fixedly installed and is arranged on determine dividing plate 31 and can be with respect to selecting powder case
Body deflectable deflection dividing plate 32, when the top deflecting dividing plate 32 deflects to the direction near first material outlet 3, for example partially
When going to the position B shown in Fig. 2, the inlet calibre of first material outlet 3 diminishes, and big particle diameter material is in first material outlet 3
Discharge capacity reduces, and ratio in remaining material to be selected for the big particle diameter material becomes big；On the top of deflection dividing plate 32 near the second thing
During the direction deflection of material outlet 4, such as when deflecting into the position A shown in Fig. 2, the inlet calibre of first material outlet 3 becomes big, greatly
