Abstract

The utility model discloses a self-rotary discharger with a pendulum roller, including a connecting rod 1, a pendulum arm 2, a ratchet wheel 3, a pair of ratchet pawls 4 and a tooth roller 6. The pendulum arm is arranged on the connecting rod 1. The ratchet pawl 4 is arranged on the pendulum arm 2 through the small shaft 5. The ratchet wheel 3 is arranged on the tooth roller 6. The ratchet wheel 3, tooth roller 6 and ratchet pawl 4 are all positioned inside the pendulum arm 2, which is characterized in that two ratchet pawls 4 are arranged again on the pendulum arm. The outside of the pendulum arm 2 is provided with an overrunning ratchet wheel 8, a crank 9 and an overrunning ratchet pawl 7. The crank 9 is connected with the ratchet pawl 4 through the small shaft 5. The overrunning ratchet pawl 7 is arranged on the connecting rod. The utility model not only has the advantages of uniform discharging materials and stable roasting process, but also overcomes the disadvantages of uneven wear, bending transformation or even rupture of the tooth roller.

Description

Rotation pendulum roll row glassware

Technical field the utility model relates to a kind of removal device that is used for metallurgical industry pellet ore shaft furnace, building material industry kiln etc.

The background technology shaft furnace is one of pellet ore production method, output accounts for 1/3 of national total output, shaft furnace process is produced pellet ore, it is simple to have equipment, easy to manufacture, and capital expenditure is few, advantages such as operating maintenance is convenient, become the pellet ore production equipment of unique distinct Chinese characteristics, existing forward large scale development, the shaft furnace technology has exported the U.S..

The discharge mechanism of shaft furnace generally is to adopt discaling roll discharge machine, promptly by many discaling rolls and connect, level installs and to constitute, because single (directly) is to stressed, discaling roll wearing and tearing inequality in hot environment, becoming bent distortion and even fracture is the common fault of discaling roll discharge machine, so that be regarded as and cure, just looking " normally ".

At present, shaft furnace discaling roll marker method has two kinds, and a kind of is discaling roll swing (36-43.5 degree) discharge, and this marker method is the most reasonable, and roasting technique is best, shortcoming be discaling roll in time (10-15 minute/time) lead phase, thereby cause equipment fault inevitably; Another kind is then the batch (-type) discharge of dead beat that it does not only possess the advantage of pendulum roll row material, and the discharge ability will reduce by 1/2.

The summary of the invention the purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, a kind of improved removal device is provided, this removal device had both had advantages such as pendulum roll row material is even, roasting technique is stable, can overcome the drawback of discaling roll wearing and tearing inequality, flexural deformation even fracture again, and prolong the service life of discaling roll.

For realizing that the technical scheme that above-mentioned purpose of the present utility model adopts is: the utility model comprises connecting rod, swing arm, ratchet, a pair of ratchet, discaling roll, swing arm is installed on the connecting rod, ratchet is installed in the swing arm by little axle, ratchet is installed on the discaling roll, ratchet, discaling roll and ratchet all are positioned at the inboard of swing arm, its design feature is: install two ratchets in swing arm again additional, be equipped with in the outside of swing arm and surmount ratchet, crank and to surmount ratchet, crank links to each other with ratchet by little axle, surmounts ratchet and is installed on the connecting rod.

It is even that the utility model had both kept in the prior art pendulum roll row material, advantages such as roasting technique is stable, simultaneously, owing on the pendulum roller, increase by two ratchets again, on little axle, crank is housed, crank and the coaxial installation of ratchet, and installed in the outside of swing arm and to have surmounted ratchet, on connecting rod, be equipped with and surmount ratchet, thereby the ratchet that surmounts that is contained on the connecting rod promotes to be contained in surmounting the ratchet revolution and surmounting angle of rocking arm of the rocking arm outside, the projection that surmounts on the ratchet lifts unloaded ratchet by little axle and crank, and discaling roll is static during backhaul, and all ratchets are return a tooth, when put on a left side again, the operation again of former load ratchet, crank and projection break away from, and unloaded ratchet enters accurate operating position, begin operation during backhaul, so go round and begin again.Thereby the utility model is in pendulum roll row material, discaling roll automatically, off and on, periodically turns round an angle---replacing a scope of operation (arc), make the mechanical performance of the steel of the former scope of operation (arc) portion before reaching abnormal limiting temperature as yet, not enter the cooling cycle, keep steel original (intensity, hardness, percentage elongation etc.) performance, fundamentally eliminated the discaling roll fault lead because of, prolonged service life of discaling roll.

Description of drawings Fig. 1 is the main transmission figure of the utility model embodiment.

Fig. 2 is the phasor of leading of the utility model embodiment.

The specific embodiment is done further detailed description below in conjunction with the drawings and specific embodiments to the utility model.

By Fig. 1, Fig. 2 as can be seen, rotation pendulum roll row glassware contains connecting rod 1, swing arm 2, ratchet 3, ratchet 4, little axle 5, surmount ratchet 8, surmount ratchet 7, discaling roll 6 and crank 9, swing arm 2 is provided with four ratchets 4, swing arm 2 is installed on the connecting rod 1, ratchet 4 is installed in the swing arm 2 by little axle 5, ratchet 3 is installed on the discaling roll 6, ratchet 3, discaling roll 6 and ratchet 4 all are positioned at the inboard of swing arm 2, also be equipped with in the outside of swing arm 2 and surmount ratchet 8, crank 9 and surmount ratchet 7, crank 9 links to each other with ratchet 4 by little 5, surmounts ratchet 7 and is installed on the connecting rod 1, surmounts the outside that ratchet 8 is installed in swing arm 2.Connecting rod 1 drives swing arm 2 and swings, and the ratchet 3 drive discaling rolls that the ratchet 4 of assembling in the swing arm 2 promotes to be contained on the discaling roll 6 are swung synchronously, and this is the basic exercise of discharge.What be contained in swing arm 2 outsides surmounts ratchet 8, do the time spent in no external force, it and swing arm 2 are synchronized with the movement, when swing arm 2 left-hands are swung, be contained in and surmount ratchet 7 variation of relative distance during with swing arm 2 relative motions on the connecting rod 5 by connecting rod 1, promotion surmounts ratchet 8 left-hand rotations and surmounts 2 one angles of swing arm, and meanwhile, the projection that surmounts on the ratchet 8 lifts empty lotus ratchet 4 by the crank 9 on the little axle 5, discaling roll 6 is static during backhaul, all ratchet 4 synchronous slow astern teeth, when put on a left side again, the operation again of former load ratchet 4, crank 9 breaks away from the projection that surmounts on the ratchet 8, unloaded ratchet 4 enters accurate job position, begins operation during backhaul, goes round and begins again.The ratio that discaling roll is led with hunting frequency is 1/4, and leading phase cycle is 8-10 minute.
