Description
Technical field
Powder field of test instrument is the utility model is related to, specifically, is related to a kind of quick angle of repose of high stability and surveys
Determine instrument.
Background technology
With flourishing for powder body material, the requirement to quality is more and more stricter, wherein, the fluidity determining of particulate material
The quality of its packed density to mould, in production process, if adjustment in time can greatly reduce the fraction defective of subsequent product,
Therefore, increasing powder manufacturer or the mobility of powder body material is begun to focus on using producer.
At present, powder mobility is mainly characterized with the angle of repose of powder, and angle tester of resting in peace mainly has following several
Method of testing：
1st, injection method, i.e., by funnel, by powder, from top, discharge is stacked on horizontal plane, forms circular cone material heap.Typically have
Two kinds of implementation methods：(1) round platform diameter D is certain, and measure material stack height H obtains angle of repose, and this method application is more universal；
(2) untill powder continuously being accumulated into funnel bottom, i.e., H is certain, and measure D obtains angle of repose, and this method is simple, but inapplicable
In easy rolling or the powder of good fluidity.
2nd, exclusive method, that is, the powder of a hydrostatic column is previously charged into, is excluded by the circular hole of hydrostatic column bottom, when
After discharge flow stops, the powder in container forms a turbination funnel space, determines H and obtains angle of repose by D, should
Method is simple, but is not suitable for the strong powder of adhesion.
3rd, gradient method, that is, the powder being previously charged into a cylindrical tube body, by slow rotating cylinder, powder is made because tilting
And slid along surface, and then angle of repose is measured, this method is not suitable for the strong powder of adhesion yet.
The angle of repose that different method of testings obtains slightly has difference, and value of the injection method generally than exclusive method or gradient method is small.
Same process, it is as a result also variant because test device structure is different with test parameter, generally enter by corresponding testing standard
OK, such as national standard or JIS standards.
Due to the requirement of yield or material uniformity, powder body material needs to adjust angle of repose in time in process of production, carries
High product mobility.Existing angle tester of resting in peace there are problems that in testing it is following some：1st, after the completion of testing, powder is general
Testboard can be covered with, and it has to be ensured that testboard is totally without material during test next time, it is therefore necessary to appropriate cleaning, scale removal process must
So original testing level can be caused to be broken, cause the testing time to extend；2nd, adopted during existing method of testing measurement powder height
Template is mostly made using stainless iron material, easily causes material to adsorb when measuring magnetic material, test result is not
Accurately, meanwhile, template is easy to the particulate material to touch scattered in folding process, causes test crash；3rd, prolonging with usage time
Long, certain deformation can all occur for fixture, workbench, funnel etc., cause original level meter no longer accurate, cause material
Tilted to side, offset measurement result.

Brief description of the drawings
Fig. 1 is a kind of working state schematic representation of embodiment of the utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment：
Reference picture 1, the quick Measuring Apparatus for Stopping Angle of high stability described in the utility model, including it is horizontal workbench 1, solid
It is scheduled on the vertical support bar 6 on workbench 1, the horizontal support bar 19 in vertical support bar 6 and installed in horizontal support
Funnel 18 on bar 19；Level meter 2, four top corner parts of the bottom surface of the workbench 1 are provided with the table top of the workbench 1
Position is respectively equipped with leveling bolt 3.
The bottom of the vertical support bar 6 is fixed on the inside of 1 one sides of workbench；The work of the underface of the funnel 18
Make table top and be provided with transparent culture dish 17, the lower section of the culture dish 17 is provided with transparent culture dish supporting plate 16, the training
Ware supporting plate 16 is supported to be structure as a whole with culture dish 17.The centre point 20 at the culture dish bottom plate center is with being located on work top
Standard point 21 keep consistency from top to bottom and being on same vertical line.Tied using the integration being movably arranged on work top
The culture dish supporting plate and culture dish of structure, the whole process of cleaning equipment can be caused to become extremely simple, and do not interfered with original
Horizontal adjustment, so as to the service life of greatly extended testing system instrument, reduce the time of retest.
Graduation mark 8 is labeled with the body of rod of the vertical support bar 6, and height is installed in vertical support bar 6 and adjusted
Device, in the present embodiment, the arrangement for adjusting height is logical using the laser pen 9 for being built-in with lifter rack, the laser pen 9
Lifting bolt 7 is crossed in vertical support bar 6, the laser pen 9 is marked with horizontal normal line 10.Surveyed by laser pen 9
The piling height of powder body material is measured, material absorption or template touch material cone angle scattered caused by avoiding original method of testing possibility
The problems such as, meanwhile, laser rays is more straight, reduce further error range.As other embodiment of the present utility model, the height
Degree adjusting means can also use stainless steel gage, slowly adjusted by elevation and subsidence regulating device highly, also can high degree avoid
Error problem.
The upper end of the vertical support bar 6 is provided with chuck 5, and one end of the horizontal support bar 19 passes through fastening bolt 4
On chuck 5；The middle part of the horizontal support bar 19 is provided with ball groove 11, and gravitation ball 15 is provided with ball groove 11, described heavy
Power ball 15 is connected with plumb line 13, and the other end of the plumb line 13 is fixed on the bottom of ball groove 11；The ball groove 11 just under
The work top of side is provided with standard point 14 of hanging down again.By introducing plumb line, can ensure on the basis of work top level whole
Individual framework all in the range of established standardses, meanwhile, using multiple standard points be able to ensure that test process accuracy height.
As shown in figure 1, the course of work of the quick Measuring Apparatus for Stopping Angle of high stability described in the present embodiment is summarized as follows：
