Background technology:
The barrel-shaped crucible that fills crude magnesium and refining agent is put into the refining resistance furnace add thermal response, to remove the purity of impurity, raising magnesium.Refining finishes, take out magnesium after, must be with overhead traveling crane with the crucible handling to magnesium crucible cleaning machine.Clamp crucible, the crucible of tumbling manually claws and cleans inner surface with instrument with the reaction residues in it to correct position.At present, magnesium crucible cleaning machine passes to rotating cylinder with moment of torsion after passing through the two-stage gear reduction by common electric machine.Gear protects with protective cover.As anchor clamps, the curved bar on the rotating cylinder is pushed down the ring flange on the crucible, and chock pins curved bar.The axle supporting form is the bearing block that rolling bearing is put into casting.Motor, protective cover, bearing block all are fixed by bolts on the support.This structure not only expends manufacturing cost, increases floor space, no motor overload safeguard measure; and to the not regulation of the limit of tumbling; in case Electric Machine Control inefficacy or people may cause hot-engine sludge to be poured out rapidly for maloperation makes the crucible flip angle excessive, cause the accident.
Summary of the invention:
The objective of the invention is: provide a kind of reasonable in design, novel structure, reliable in action, novel magnesium crucible cleaning machine easy to maintenance, to overcome the deficiencies in the prior art.
The present invention constitutes like this: it comprises rotating cylinder (17), on the top of rotating cylinder (17) otic placode (11) is arranged, and otic placode (11) is connected with curved bar (7); Axle (8) and axle (15) are arranged in the stage casing of rotating cylinder (17), and axle (8) is connected with support (1) by bearing (14) respectively with axle (15), and axle (8) is connected with motor (3); Crucible (9) is in rotating cylinder (17), and flange seat (10) drops on rotating cylinder (17) upper surface, and rotation curved bar (7) is connected with flange seat (10).
Otic placode (11) is connected with curved bar (7) with bearing pin (5); Per two of otic placode (11) is one group, and every group of otic placode (11) gone up boring, inserts chock (6) in the hole, freely overturns with restriction curved bar (7), thereby compresses crucible (9).
Every group of otic placode (11) joined a curved bar (7), bearing pin (5) and chock (6), the vector of the gravity of band slag crucible (9) and thrust and definite when the thickness of the group number of otic placode (11) and curved bar (7) thereof and quantity basis are tumbled.
Bearing (14) is rolling bearing units, and axle (8) links by shaft coupling (4) and motor (3).The speed reducing ratio of motor (3) is 800-900, and is furnished with brake, can realize rotating at a slow speed, guarantees safety.
Between motor (3) and the support (1) adjustment plate (2) is arranged, between bearing (14) and the support (1) adjustment plate (16) is arranged, and be connected and fixed by bolt respectively, the thickness of adjustment plate (2), (16) can be adjusted, thereby guarantees the axiality of a whole set of power transmission shaft.
On support (1), be provided with two near switch (13), go up welding near plate (12),, rotating cylinder (17) limit of tumbling is limited by the transmission and the mechanical action of electric signal at rotating cylinder (17).
During work, to rotating cylinder (17), rotation curved bar (7) blocks the flange seat (10) on the crucible to overhead traveling crane with crucible (9) handling, inserts chock (6), makes crucible (9) and rotating cylinder (17) fixing reliable.Motor (3) drives crucible (9) rotation by shaft coupling (4), rotating cylinder (17), and the rotation maximum angle is by controlling near switch (13).Make motor (3) stall in case run into external force, then shaft coupling (4) can play overload protective function.After cleaning finishes, reverse-rotatable motor, crucible (9) resets, and extracts chock (6), opens curved bar (7), and overhead traveling crane hangs away crucible (9), waits for next operation.
Owing to adopted above-mentioned technology, the present invention both to save manufacturing cost, reduce floor space, motor is carried out overload protection, can ensure operator's personal safety again.
The specific embodiment:
Embodiments of the invention: according to volume, weight design and making rotating cylinder 17 and each part thereof of magnesium crucible, choose motor 3, bearing 14 etc., the speed reducing ratio of motor 3 is * * 800-900, and is furnished with brake; Assemble according to shown in the accompanying drawing.At first, otic placode 11 one group of per two composition, the even distribution are welded on the top of rotating cylinder 17, every group of otic placode 11 usefulness bearing pins 5 connect curved bars 7; Secondly,, be supported on the support 1 with two rolling bearing units 14 respectively, on pad between rolling bearing units 14 and the support 1, adjust plate 16 and use bolted at the appropriate location, stage casing of rotating cylinder 17 welding axle 8 and axle 15; Axle 8 is linked by shaft coupling 4 and motor 3, on pad between motor 3 and the support 1, adjust plate 2 and use bolted; Then, install two near switch 13 on support 1, the relevant position on rotating cylinder 17 is welded one near plate 12; (when promptly working) at last, with overhead traveling crane with crucible 9 handlings to rotating cylinder 17, flange seat 10 drops on rotating cylinder 17 upper surfaces, blocks flange seat 10 on the crucible 9 with rotation curved bar 7, and inserts chock 6, and crucible 9 is fixed in the rotating cylinder 17.
