When the invention is used, firstly, the workbench 1 is moved, the furnace door butt-joint platform 2 of the discharging system is inserted into a furnace door of a vacuum smelting furnace to realize perfect butt joint, four universal wheels 14 below the workbench 1 are positioned, an operator stands on an antiskid operating platform 11 to discharge the rapid hardening sheets in the furnace, the rapid hardening sheets discharged out of the furnace can be directly poured into the lower sliding runner 3, two sides of the lower sliding runner 3 extend upwards to form baffles 10 which can prevent the rapid hardening sheets from falling on the ground, the lower sliding runner 3 with a certain inclination angle can enable the rapid hardening sheets to easily slide to a slideway outlet 9 at the tail end of the runner according to the direction of the runner, wherein each smelting furnace has different models, and the width and the extension size of the furnace door butt-joint platform 2 which meet the requirements and the inclination angle of the lower sliding runner 3 which can enable the rapid hardening sheets to freely slide down can be manufactured according to the size and the height of the furnace door of the smelting furnace. The dust collector 4 arranged in the discharging system can be opened at any time to timely suck away dust in and out of the furnace, and the dust in the furnace is easy to fly due to overlarge discharging action in the discharging process, and the dust in the furnace is higher in heavy rare earth content, so that the dust is sucked into the body to cause discomfort and is timely cleaned to ensure the sanitation and safety.
The connection of the discharging system and the screening system changes two working procedures into one, and combines the two working procedures of discharging, collecting and screening into one working procedure of discharging, screening and collecting, thereby achieving the current single-line flow operation by the previous multi-line operation, improving the efficiency, reducing the manpower and material resources, reducing the production cost, shortening the production period, improving the production efficiency, and effectively preventing the rapid hardening sheets from falling into the furnace or the ground by the large-area gliding flow channel 3. Redesigned piece is thick to be screened cylinder 6 and motor 20 transmission, during operation motor 20 drive pivot 19 rotates, and pivot 19 drives first carousel 21 and second carousel 22 and rotates, and first carousel 21 is tangent with first ring flange 15, and then drives first ring flange 15 and rotate to make the cylinder rotate, the piece freely glides in the cylinder of being convenient for rapid hardening, and second carousel 22 is connected with third carousel 23 through driving chain 24, third carousel 23 with the cylinder 27 of cylinder bottom is tangent. First ring flange 15 is the full package ring flange dish, when cylinder 27 is connected with the full package ring flange dish, the periphery of cylinder 27 all is located the full package ring flange dish, first carousel 21 is tangent with the full package ring flange dish, second ring flange 16 is the half package ring flange dish, when cylinder 27 is connected with the half package ring flange dish, the peripheral part of cylinder 27 is located outside the half package ring flange dish, third carousel 23 is tangent with the outer bottom cylinder 27 of half package ring flange dish, when accomplishing the cylinder pivoted, a cylinder 27 of second ring flange 16 bottommost rotates under the effect of third carousel 23, can be with block or be about to block the rapid hardening piece of material and withdraw from cylinder 27 gap or sieve into. The cylinder setting of downward sloping, along with the self weight of rotation and rapid hardening piece, possible continuous transport, the rapid hardening piece that accords with the requirement all falls to the certified materials discharge gate from the gap, and the rapid hardening piece that does not accord with the requirement can in time discharge from 8 discharge gates of non-certified materials, does not pile up, improves screening speed and production efficiency. The other advantage of the rotation of the cylinder 27 is to ensure that the stress points of the contacted cylinder 27 are different every time the rapid hardening tablets are screened and collided, thereby reducing the deformation probability of the cylinder 27 and prolonging the service life of the equipment. In actual operation, the rotating speed of the motor 20 is not too fast, the rapid hardening pieces are small and light, the rapid hardening pieces are easy to centrifuge due to the too fast rotating speed, and the screening function is ineffective.
And because the cylinders 27 comprise a first shaft section 28, a second shaft section 29 and a third shaft section 30 with successively reduced diameters, the gap between the first shaft sections 28 between two adjacent cylinders 27 is a, the gap between the second shaft sections 29 between two adjacent cylinders 27 is b, the gap between the third shaft sections 30 between two adjacent cylinders 27 is c, and because two adjacent cylinders 27 are parallel to each other, a < b < c, the gap between two adjacent cylinders 27 is successively increased from the first shaft section 28 to the third shaft section 30, so that when the quick-setting tablet moves from the first shaft section 28 to the third shaft section 30, the quick-setting tablet enters the first qualified material discharge port 7 through the gap between two adjacent first shaft sections 28 according to the size of the quick-setting tablet, when the size of the quick-setting tablet is smaller than a, the quick-setting tablet enters the second qualified material discharge port 12 through the gap between two adjacent second shaft sections 29, when the size specification of the rapid hardening piece is larger than b and is smaller than c, the rapid hardening piece enters the third qualified material discharge port 13 through the gap between the two adjacent third shaft sections 30, and when the size specification of the rapid hardening piece is larger than c, the rapid hardening piece enters the unqualified material discharge port 8, so that multistage screening is completed, the screening precision is high, the size specification phase difference of the rapid hardening piece is smaller, and the practical use can be better met.
In addition, the full-wrapping ring flange can rotate relative to the half-wrapping ring flange, and the screening precision is adjusted by enabling the half-wrapping ring flange and the full-wrapping ring flange to be in a clearance size between two adjacent cylinders 27. The periphery of the slice thickness screening roller 6 is provided with a barrel shell 25, the barrel shell 25 is fixed on a rolling support, and the roller rotates constantly, so that individual quick-hardening slices are inevitably discharged from gaps above the roller, and the quick-hardening slices can be prevented from falling outside by arranging a hollow shell, and the barrel shell 25 is provided with an observation window 26, so that the operation condition in the slice thickness screening roller 6 can be observed constantly.
