Abstract
The utility model discloses a plasticity index measuring instrument which can measure the high-alumina or the clay refractory plasticity. The ram is usually hung by the hanging mechanism, so during the operating procedure, hanging and loosening the ram are not convenient, which influences the measuring result. In the utility model, a supporting mechanism is arranged on a bracket to support the ram instead of the hanging mechanism. The ram can be easily held and loosened by the supporting mechanism, which can ensure the stability and the reliability of the test.
Description
The utility model relates to a kind of tester of measuring the plasticity index of high alumina matter or clay matter plastic refractory.
The plasticity index of high alumina matter or clay matter plastic refractory is to hit real strength detection instrument with the mechanical industry molding sand after improving to measure.This determining instrument has a support, spanner, rule and vertical pivot are housed on the support, tup, cam and pressure head are housed on the vertical pivot, handle is fixed on the cam, forming tube, fore-set and base are the appurtenances of this determining instrument, and a hanging mechanism also is housed on the support of this determining instrument, and moving hanging mechanism with hand can tangle tup or unclamp, inconvenient operation produces error to experimental data.
Task of the present utility model is tester easy to operate, that test figure is measured the plasticity index of high alumina matter or clay matter plastic refractory accurately of design.
Solution is: the tup erecting by overhang that the mechanical industry molding sand is hit on the real strength detection instrument changes the tup fulcrum arrangement into.On support (2), adorn a rest pad (9) and hold tup (3), and on support (2), adorn the upper end that a spring (13) connects rest pad (9), a fulcrum arrangement of support (2), rest pad (9) and spring (13) formation tup (3).Rest pad (9) is made by metal material.
Measure the height dimension of sample, can make rest pad (9) hold tup (3), and make determination data not be subjected to the influence of tup (3).In case the hammering sample, with hand rotating cam (4), tup (3) raises, and rest pad (9) rotates an angle under the effect of spring (13), the promptly indirect serially hammering sample of tup (3), and the influence of not supported (9).Bring convenience to operation.

Fig. 2: the side view of a plasticity index tester when the compacting sample.
Fig. 3: the front view of fore-set (11).
Fig. 4: the front view of base (12).
Fig. 1 and Fig. 2 have described an embodiment of the present utility model: rest pad (9) is housed on support (2), the both sides that are positioned at vertical pivot (7) of its two arm symmetries are propped up and are held tup (3), support (2) both sides are connected with the spring (13) of two symmetries, they are connected with two arms of rest pad (9) respectively, rest pad (9) is subjected to the effect of spring (13), handle (5) is fixed on the cam (4), cam (4) and pressure head (6) are contained on the vertical pivot (7), and pressure head (6) is pushed down test portion (14).
Rotating cam (4), tup (3) rises, and rest pad (9) rotates an angle under spring (13) effect, the influence of not supported (9) when tup (3) falls, hammering test portion (14) is made garden cylindricality sample to graininess test portion (14) indirectly.
Press lower ejector lever (8), vertical pivot (7) rises, take off the forming tube (10) that sample is housed from support (2), eject sample in the forming tube (10) with fore-set (11), base (12) is placed on the support (2) together with sample, by the upper surface of vertical pivot (7), on rule (1), read the height dimension of sample before and after hammering, calculate the plasticity index (Wa) of this sample with following formula:
Wa=(L
O-L
1)/(L
0) * 100%
In the formula: L
0Be subjected to the height (mm) of the preceding sample of hammering,
L
1Be subjected to the height (mm) of sample after the hammering.
In the present embodiment, the material of making rest pad (9) usefulness is steel.
Claims (3)
1, a kind of tester of measuring the plasticity index of high alumina matter or clay matter plastic refractory, has a support, spanner, rule and vertical pivot are housed on the support, tup, cam and pressure head are housed on the vertical pivot, handle is fixed on the cam, it is characterized in that: rest pad (9) is housed on the support (2), and an end of spring (13) is connected with rest pad (9), the other end is connected with support (2), constitutes a supporting device rest tup (3).
2, according to the tester of claim 1, it is characterized in that the rest pad (9) of rest tup (3) is subjected to the effect of spring (13), in case tup (3) rises, rest pad (9) can rotate an angle.
3,, it is characterized in that rest pad (9) made by metal material according to the tester of claim 1 or 2.
