Abstract
The utility model belongs to a determining device for rheological parameter. When the rotary shaft of the inner vane of the utility model agitates materials in an outer drum by different rotary speeds, the shearing force can be transmitted to the outer drum by the determined material. As a consequence, torque values acting on the wall of the outer drum under different rotary speeds can be determined, and two rheological parameters of the yield value and the plastic viscosity can be calculated. The specific structure comprises a rotary shaft which is connected with an agitating vane agitating the materials placed in the drum, and the wall of the outer drum is provided with a force determining mechanism which can determine the torque value acting on the wall of the outer drum during the rotation. The force determining mechanism is composed of a force determining point, a force transmitting component and a force determining device. The mechanism has simple structure, accurate torque value, convenient and automatic record.
Description
The utility model belongs to the rheological parameter analyzer.
Existing rheological parameter analyzer is to calculate rheological parameter by the torque value of measuring rotating shaft and the rotating speed of urceolus, the weak point of this rheological parameter analyzer is a complex structure, in the mensuration process, influence factor to torque value is more, measure the method difficulty of torque value, and be not easy to automatic record.
The purpose of this utility model is to make mensuration two parameter flow graphs simple in structure, and torque value is accurate, and is convenient to automatic record.
Intra vane of the present utility model changes and revolves axle and change when stirring material in the urceolus inward turning, and tested material is given the urceolus barrel with shear transfer, because the resistance of outer tube wall and material is greater than shearing force, so can record torque value on outer tube wall.Force measuring machine is made up of force-detecting position, force transmission element, dynamometer, and connects at the tangential direction straight line of outer tube wall.
Fig. 1 is the structural drawing that intra vane rotation urceolus is measured two parameter flow graphs.
Fig. 2 is the A-A sectional view of stirring vane that intra vane rotation urceolus is measured two parameter flow graphs Fig. 1 when being 0 ° or 360 °.
The utility model is implemented as follows:
With reference to Fig. 1, Fig. 2, the stirring vane 2 that can change angle (0 °～360 °) arbitrarily is set on the turning axle 1 of the present utility model, material is placed in the urceolus 3, turning axle 1 is vertical being inserted in the material with the union body of stirring vane 2.Urceolus 3 outer walls are provided with the force-detecting position 4 of measuring torque value.When stirring vane 2 stirs material, tested material will stir shear transfer and give urceolus 3, and at this moment the force measuring machine of being made up of force transmission element 5 connection force-detecting positions 4 and dynamometer 6 just can record torque value on urceolus 3 outer walls.Dynamometer 6 must be connected in force-detecting position 4 by force transmission element 5 in the tangential direction of urceolus 3, so that accurately measure the torque value of relative rotation center, the rotating speed difference of turning axle 1 is measured different torque values, and this torque value is represented the shear stress of 2 pairs of tested materials of stirring vane exactly.Dynamometer 6 can adopt spring dynamometer, counterweight dynamometer and force cell.Adopt force cell to be connected, constitute automatic analyzer with self-recording device.After having recorded the rotating speed of torque value and urceolus, just can calculate rheology two parameters, i.e. yield value and plastic viscosity.
The utility model is compared with original technology, and operating mechanism and mechanism for testing are all simple, accurate, and it is few to be easy to automatic record and disturbing factor.
