The corresponding component of two crucible rotary modules is in same plan-position and is parallel to each other.The following describes the detailed technology scheme of one of them crucible rotary module, the crucible rotary module comprises crucible motor, rotating shaft, crucible, crucible fixed cover, clamp nut.The crucible motor is separately fixed on the lower carriage, and links to each other with rotating shaft; The top of rotating shaft connects the crucible fixed cover, and crucible fixed cover the inside is provided with crucible, and the outside connects clamp nut.
The corresponding component of two stirring silk rotary modules is in same plan-position and is parallel to each other.The following describes the detailed technology scheme that one of them stirs the silk rotary module, stir the silk rotary module and comprise stirring motor, rubber sleeve, stirring silk.Stirring motor is arranged on the upper bracket, and rubber sleeve is enclosed within on the motor shaft of stirring motor; Stir the motor shaft that the silk upper end connects stirring motor, the lower end is separately positioned on crucible inside.
The invention has the beneficial effects as follows: change the method for traditional manual measurement bituminous coal caking index, reduce human error, realize all automatic measurement.All measurement data adopt computer automation output to show, have prevented that effectively the part experimental data from being distorted, and have increased science, authenticity and the accuracy of experiment, and the reappearance and stability that have guaranteed test data.With respect to traditional manual alr mode, saved cost of human resources, overcome the shortcoming of artificial mixing inhomogeneities; With respect to single crucible agitator, can carry out the stirring of two parts of anthracite samples simultaneously, mixing time is saved greatly.For follow-up test (anthracite caking index testing experiment) provides more convenient, reliable laboratory sample.
The specific embodiment
Biasing motor 27 drives driving shaft 26 and does the positive and negative motion of 45 degree, driving shaft 26 drives 20 motions of two driven gears by driving gear 19, two driven gears 20 drive 9 motions of two lower fulcrum bars by two driven shafts 13 respectively, and then drive 23 motions of two upper rack posts respectively.Two upper rack posts 23 drive respectively two upper junction plates 22, two upper brackets 1, stirring motor 28, two stir silk 3 motions, do the positive and negative motion of 45 degree thereby realize stirring the silk module; Two lower fulcrum bars 9 drive two middle connecting plates 21, two lower connecting plates 15, two medium-height trestles 8, two lower carriages 9, two crucible motors 29, two crucibles 4, two crucible fixed covers 5, two clamp nut 6 motions respectively, realize that the crucible rotary module does the positive and negative motion of 45 degree.Lower fulcrum bar 9 all the time with upper rack posts 23 synchronized movement, realized the positive and negative swing of 45 degree that crucible is whole with stirring silk.
Two crucible motors 29 drive 5 rotations of two crucible fixed covers by two rotating shafts 7 respectively, and two crucible fixed cover 5 rotations rely on the pressure of frictional force, 6 pairs of two crucibles 4 of two clamp nuts, drive two crucible 4 low speed and turn clockwise.Two stirring motors 28 drive two rubber sleeves 2, two respectively and stir silk 3 and do to be rotated counterclockwise at a high speed.
The course of work: at first dispose two parts of anthracite samples, and place it in respectively in two crucibles 4, biasing motor 27 drives driving gears 19 motions by driving shaft 25, and driving gear 19 drives driven shaft 13 and does positive and negative 45 degree swings by two driven gears 20, two.Two lower fulcrum bars 9 that are separately positioned on two driven shafts 13 drive 23 motions of two upper rack posts, and drive pole module, crucible module and stirring module are synchronized with the movement the positive and negative swing of whole 45 degree of realization.In 45 degree swings, two crucible motors 29 respectively by two rotating shafts 7 drive two crucible fixed covers 5, two clamp nuts 6, two crucibles 4 carry out clockwise low speed rotation, rotating speed is that per minute 15 changes; Two stirring motors 28 are with two moving rubber sleeves 2, two to stir silk 3 respectively to carry out counterclockwise rotation at a high speed, and Revolution Per Minute is 150 to change.After about 1 minute 45 seconds, biasing motor 27 rotates back into initial position gradually, guarantees that two upper rack posts A23 go to the plumb position after 15 seconds.Whole whipping process lasts 2 minutes.
