Description
Technical field
The present invention relates to test equipment technical field, in particular to a kind of ash melting tester.
Background technique
Currently, ash in the market melts in tester, sample is installed on furnace core, and furnace core is installed on middle supporting plate, middle support
Plate is carried out by feed screw nut with screw body affixed.By being installed on driving screw rod lower section and far from first motor of burner hearth
The upper and lower movement of supporting plate in screw rod rotation realization is driven, the loading and sample presentation work of sample are realized with this.
After sample is sent to the predetermined position of burner hearth by first motor, by being installed below burner hearth and close to burner hearth
Rotary motion of the second motor driven sample in burner hearth, observed in order to which video camera passes through a fixed hole position on burner hearth
To the test situation of sample.
But need to be mounted so that two motors, mechanism is limited, driving screw rod is located at the non-central position of middle supporting plate
It sets, so that forming the arm of force between the center of gravity and screw rod of middle pallet part, and a gravitational moment is thus generated, so that middle supporting plate and silk
Verticality between bar, through after a period of time later can have greatly changed so that middle supporting plate is no longer vertical with screw rod.This
When sample can directly result in furnace core and be rotated in burner hearth, since the gap between furnace core and burner hearth is very small, there is furnace
