Description
Technical field
The invention mainly relates to the technical field of survey tool, specifically, the present invention relates to the technical field of a kind of granule materials natural repose angle determinator.
Background technology
It is dried in granule materials character research process, for the smooth delivery of power of granule materials, needs to test the natural repose angle of granule materials, to reach the purpose of appropriate design conveying equipment.Therefore must take suitable mensuration measure, when using different assay methods, the accuracy of mensuration and effect can be different.nullGenerally，In order to ensure the mensuration effect of granule materials natural repose angle，Can use and dry granule materials is flowed down slowly from funnel，After granule materials forms cone，The diameter piled up by ruler measurement granule materials cone，And then calculate packing radius R，Determine the height H that cone is piled up again，Then angle theta is obtained by the tan arctg (H/R) that negates，It is the natural repose angle of granule materials，The radius so measured with the most often there is certain error，Therefore the accuracy of test result is influenced whether，The most this method is relatively complicated，Parameter to be determined can not be directly obtained，Therefore minute is added，The artificial experiment carrying out number of times more is needed to measure under normal circumstances，For labor measurement，It suffers a disadvantage in that 1、Test relatively complicated，Take time and effort，It is difficult to Accurate Determining relative dimensions parameter；2, can not directly obtain reading, need to carry out secondary calculating, for repeatedly measuring, then amount of calculation is bigger than normal, easily produces certain error.Now need the apparatus and method of a kind of convenient and efficient, reach preferably to measure effect, i.e. accurately quickly measure the natural repose angle being dried granule materials.
Summary of the invention
The most not enough and the state of the art of defect of device during measuring for existing granule materials natural repose angle, the invention provides the rapid determination device of a kind of granule materials natural repose angle, compared with existing granule materials natural repose angle determinator, the assay device measuring granule materials natural repose angle of the present invention, carry with easy to use, measure accurately, cheap for manufacturing cost, for particulate matter natural repose angle fields of measurement, there is extensive practicality.
A kind of granule materials natural repose angle rapid determination device that the present invention provides, including angle index litter, tightening knob, operating platform, funnel, fixing bar, movable plate and supporting leg, movable plate it is provided with on operating platform, basic circle it is carved with on movable plate, corner, the operating platform back side is provided with supporting leg, both sides, operating platform front are correspondingly arranged fixing bar and angle index slide bar respectively, angle index and pointer it is provided with on angle index slide bar, pointer is fixed on angle index slide bar by tightening knob, and funnel is fixed on fixing bar by tightening knob.
In the present invention, bank of banking up in basic circle.In the present invention, operating platform is provided with horizon equipment.
In the present invention, height of landing leg can adjust.
The granule materials natural repose angle rapid determination device following beneficial effect of acquisition that enforcement the invention described above provides:
Using said structure device, the present invention can measure the natural repose angle of dry granule materials the most exactly, realize direct reading easily, and simple in construction, cleaning is quick, easy to process, low cost, measures field for particulate matter natural repose angle and has extensive practicality.
