Embodiment
As shown in Fig. 1,2 and 3, in the present embodiment, this invention comprises bumper 1 and base 2, and bumper 1 is arranged on base 2, and vibration motor 8 is housed between them.Specifically base 2 and bumper 1 fit together by elastomeric element, vibration motor 8 drives bumper 1 vibrations, realizes vertically vibrations in order of bumper 1, is furnished with cylindrical vessel 3 above bumper 1, cylindrical vessel 3 is Split type structure with bumper 1, holds parts and is fixed on bumper 1 by adding.Due to the structural limitations of cylindrical vessel 3 own, be difficult for bumper 1 fixing.Therefore at cylindrical vessel, a vessel base 5 is set for 3 times, and cylindrical vessel 3 and vessel base 5 is set to integrative-structure, can process by casting one-body molded, perhaps integrally welded structure.Stability and fastness that cylindrical vessel 3 is connected with vessel base 5 have been guaranteed like this.Vessel base 5 is fixed on bumper 1 by stepping up parts.Step up the rectilinear active grab 10 of the preferred a kind of tension of parts, one end preferred weld is fixed on vessel base 5, and the other end adds the section of holding and freely adds and hold on vessel base 5, and is easy to use, to step up effect comparatively desirable.In order further to limit cylindrical vessel 3 position degree of accuracy on bumper 1, locating piece 9 can be set on bumper 1.The locating piece 9 that is fixed on bumper 1 coordinates with vessel base 5, prevents that vessel base 5 from producing deviation because of vibrations.Also comprise support, this support is that this invents another important component part.It comprises carrier base 12, horizontal support 6 and longitudinal carrier 7, and carrier base 12 is arranged in base 2 sides, prevents that according to actual needs from regulating the position relationship between support and base 2.Longitudinal carrier 7 is arranged on carrier base 12, and horizontal support 6 is fixed on longitudinal carrier 7, and horizontal support 6 is arranged vertically with longitudinal carrier 7, horizontal support 6 is provided with through hole, this through hole is used for setting-in and inserts rod 4, inserts excellent 4 free ends and gos deep in cylindrical vessel 3, inserts rod 4 and arranges two.Horizontal support 6 also is provided with two, and is provided with through hole, increases whole stability.
The present invention specifically uses step as follows:
One, the pilot study of flow moisture point
1. before testing, the vibrations that should use accelerograph that vibrations are appeared on the stage are calibrated.
2. the sample cylindrical vessel 3 of packing into, exert pressure to sample by tamper, obtains uniform plane, then passes carriage with inserting rod 4, vertically is placed on specimen surface;
3. take frequency as 50Hz or 60Hz, acceleration is 2g rms ± 10%, shakes 6 minutes, simultaneously the reading of sense acceleration instrument.
4. the bumper vibrations after 6 minutes, are read the insertion depth that inserts rod 4.
5. if insert excellent 4 insertion depths less than 50mm, think not reach fluidization.At this moment continue to spray a certain amount of water, and stir, and repeat above-mentioned experimental procedure.
6. if insert excellent 4 insertion depths greater than 50mm, think to have reached fluidization.Calculate water cut a little less than flow moisture point according to formula.
Two, the master trip of flow moisture point:
1. carry out master trip on the basis of preliminary experiment, accurately to determine flow moisture point.
2. the water cut of increment is adjusted in pilot study last lower than the numerical value of flow moisture point.
3. by the pilot study step, carry out the test of flow moisture point with the increment after modulation.But different from pilot study is that the quantity that at every turn adds water here must not surpass 0.5% of sample general assembly (TW).
4. if about value of prior known flow moisture point should be adjusted to the water cut of increment 90% left and right of this value.
5. when reaching fluidised form, determine flow moisture point by the prescriptive procedure of standard chart.
