Description
Technical field
Especially a kind of dried particles material of the utility model natural repose angle determinator, belongs to the testing apparatus of the powder material such as milk powder, feed, also relates to the technical field widely such as drying or Design of Dust-removing System, Geotechnical Engineering, geotechnological performance test simultaneously.
Background technology
Carrying out in dried particles material properties research process, in order to the smooth delivery of power of granule materials, needing the natural repose angle of particle tested material, so that appropriate design conveying equipment.
When measuring natural repose angle, measure the angle between the centrum bus of granule materials natural packing and surface level, when adopting different assay methods, the accuracy of mensuration and effect can be different.Generally, in order to ensure the mensuration effect of granule materials natural repose angle, adopt sometimes and dried particles material is flowed down slowly from funnel, after granule materials forms centrum, with the diameter that ruler measurement granule materials cone is piled up, and then calculate packing radius R, determine the height H that cone is piled up again, then angle theta is obtained by tan of negating, be the natural repose angle of granule materials, but such measured radius with highly often there is certain error, therefore the accuracy of test result can be had influence on, this method is comparatively loaded down with trivial details simultaneously, can not directly obtain parameter to be determined, because this increasing minute, now need a kind of apparatus and method of convenient and efficient, reach desirable mensuration effect, the i.e. natural repose angle of accurate Fast Measurement dried particles material.Need the artificial experiment carrying out number of times more to measure under normal circumstances, also useful automatic digital display instrument is done experiment mensuration, and for labor measurement, its shortcoming existed is: test comparatively loaded down with trivial details, take time and effort, not easily Accurate Determining relative dimensions parameter; Directly can not obtain reading, need to carry out secondary calculating, for repeatedly measuring, then calculated amount is bigger than normal, easily produces certain error.Generally speaking, a kind of special auxiliary measuring device is lacked in prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of low-cost test device of convenient Accurate Determining granule materials natural repose angle, i.e. a kind of dried particles material natural repose angle determinator.
For achieving the above object, the utility model technical measures: comprise funnel, bell mouth, fixed bar, column, workbench, angle index, supporting leg, scale mark, basic circle, level meter and movable plate, workbench side upper vertical vertical columns, in one end of the horizontally hinged fixed bar in column upper end, the other end of fixed bar installs funnel, the bell mouth of funnel lower end is positioned at the middle part of workbench upper side, simultaneously, bottom workbench, supporting leg is installed, on workbench, middle side part embeds movable plate, movable plate surface indicia has one group of equally spaced concentric basic circle, equally distributed angle index is marked with in movable plate side, and, each basic circle all has a scale mark to be connected to corresponding angle index, all scale marks are parallel to each other and equidistantly, in workbench upper edge, level meter 11 is installed.
Wherein, fixed bar is hinged on column upper end by tightening knob.
Wherein, supporting leg is provided with level-off rotating nut.
The utility model a little or effect be, adopt said structure device, realize direct reading easily, can fast, intuitively, measure the natural repose angle of dried particles material exactly, and structure is simple, easy to process, cost is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that schematic diagram is cutd open in the utility model side.
Reference numeral comprises: funnel 1, bell mouth 2, fixed bar 3, tightening knob 4, column 5, workbench 6, angle index 7, supporting leg 8, scale mark 9, basic circle 10, level meter 11, particle stockpile 12, movable plate 13.
Embodiment
Below in conjunction with accompanying drawing and example, patent of the present invention is described further.
Embodiment 1: as shown in Figure 1 and Figure 2, the utility model comprises funnel 1, bell mouth 2, fixed bar 3, column 5, workbench 6, angle index 7, supporting leg 8, scale mark 9, basic circle 10, level meter 11 and movable plate 13.
Workbench 6 side upper vertical vertical columns 5, in one end of the horizontally hinged fixed bar 3 in column 5 upper end, the other end of fixed bar 3 installs funnel 1, the bell mouth 2 of funnel 1 lower end is positioned at the middle part of workbench 6 upper side, simultaneously, supporting leg 8 is installed bottom workbench 6, on workbench 6, middle side part embeds movable plate 13, movable plate 13 surface indicia has one group of equally spaced concentric basic circle 10, equally distributed angle index 7 is marked with in movable plate 13 side, and, each basic circle 10 all has a scale mark 9 to be connected to corresponding angle index 7, all scale marks 9 are parallel to each other and equidistantly, in workbench 6 upper edge, level meter 11 is installed.
In aforementioned, centered by basic circle 10 center of circle, when particle stockpile 12 is placed in movable plate 13 upper side, its bottom outer-edge is corresponding to the angle index 7 determined.
In aforementioned, fixed bar 3 is hinged on column 5 upper end by tightening knob 4.
In aforementioned, supporting leg 8 is provided with level-off rotating nut.Workbench 6 can be adjusted by reference levels instrument 11 by it.
In aforementioned, movable plate 13 can need to change according to different material or measuring accuracy.
When the utility model uses, by supporting leg 8 and level meter 11, workbench 6 is adjusted to level, with column 5 for axle rotates fixed bar 3, the granule materials be threaded to by funnel 1 on movable plate 13 is piled up above the center of circle of circle 10, make above the center of circle of bell mouth 2 just to accumulation circle 10, with tightening knob 4, funnel 1 is fixed on fixed bar 3, its constant height apart from workbench 6 is constant, the dried particles material mixed is added funnel 1 slowly, dried particles material evenly falls in basic circle 10 from bell mouth 2, and come along center of circle diffusion gradually, when particle stockpile conical top is just positioned at bell mouth 2 lower end, stop reinforced, now observation particle stockpile 12 amasss the angle index 7 corresponding to circumferential edge, angle index 7 is calculated apart from workbench 6 upper surface vertical range by bell mouth 2 lower end, this constant distance is constant, also namely particle stockpile 12 is constant highly all the time, this angle index numerical value is the natural repose angle of granule materials, since then can be accurate, measure the natural repose angle of all kinds of particulate material rapidly.
