Reciprocating type aluminum liquid circulating device
Technical field: the present invention relates to a kind of auxiliary device of Metal Melting, relate in particular to a kind of reciprocating type aluminum liquid circulating device of realizing that the aluminium liquid recycle stream is moving
Background technique:
Implement aluminium liquid circuit device in the at present domestic and international aluminium smelting technology and be generally mechanical centrifugal pump electromagnetic pump and permanent magnet pump
Use mechanical centrifugal aluminium liquid pump because entire pump is immersed in the high temperature aluminum liquid, adopt high-intensity high-density high purity graphite material usually.But the defective of this pump is to use the life-span short because therefore the aluminium liquid pump of graphite quality is easy to wear and tear, the use and maintenance cost height
For using electromagnetic pump, need big power electromagnetic coil and power supply unit, frequency variator, and necessary cooling water system.Therefore the cost of this pump is also very high, and power consumption is big.
And use the greatest problem of permanent magnet pump to be to use operating temperature not high, also want ad hoc air cooling system.In case and the phenomenon of the decline that is magnetic gradually influences when fine crack appears in refractory material in effective life cycle and the aluminium spout, under the effect in the magnetic field of flowing, the aluminium liquid that infiltrates crackle may make aluminium spout cracking, causes the leakage accident
Summary of the invention: the present invention seeks at problems of the prior art, provide a kind of reciprocating type aluminum liquid circulating device this reciprocating type aluminum liquid circulating device, long service life, the applicable working temperature height, cost is low, and is simple in structure.
Technological scheme of the present invention comprises support, be located at the piston-cylinder apparatus on the support, be connected with blade and tooth bar on the piston rod of described piston-cylinder apparatus respectively, the petiole of described blade is provided with the gear corresponding with described tooth bar, and the relative both sides of support are installed with the block that corresponds respectively to described tooth bar
Described support is provided with supporting guide, and described blade is connected on this supporting guide and the described piston rod through a clamp holder, and described tooth bar is connected on the groove of described clamp holder
Described blade is provided with an insulating curtain that is connected on the described support.
The present invention's simulation ' paddle ' action is changed existing rotation by the pump leaf and is carried the blade for anthropomorphic dummy's Boating type to promote to carry, and utilizes blade moving in the aluminium liquid bath, it is simple to promote aluminium liquid fluidal texture, operation, easy to maintenance can be used for the various type of furnaces, the stove of various capacity.Can change the travelling speed of blade according to the needs of fusion process different phase, can regulate aluminium liquid circuit flow at any time arbitrarily.Being immersed in the aluminium liquid only is blade, the blade of the extraordinary Composite Preparation that the good liquid of anti-aluminium of the replacing anti-chilling and shock heating performance of simple and convenient employing high strength washes away in molten aluminium process, and long service life, it is low to make maintenance cost
To be principle of the invention structural representation Fig. 2 be the structural representation of the piston rod movement among Fig. 1 after another end point of travel to description of drawings: Fig. 1
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is further described as shown in Figure 1, piston-cylinder apparatus 7 supporting guides 8 be fixedly arranged on clamp holder 5 on the aluminium liquid bath 1 notch support place on the supporting guide 8 by guiding groove set on it and the free end blade 2 that is fixed in piston rod 6 by its shape loom and clamp holder 5 slightly drive fit be connected in the slotted eye of clamp holder 5.Groove 12 upper racks 3 that tooth bar 3 is connected in clamp holder 5 corresponding to the gear 4 on the axle shape loom that is fixed on blade 2 notch that insulating curtain 11 on corresponding with the two ends of the tooth bar 3 respectively opposite end that is fixed in aluminium liquid bath 1 notch support of two block 9a 9b is positioned at aluminium liquid bath 1 that can slide in this groove 12 is connected on blade 2 and the aluminium liquid bath 1 notch support
During work, as shown in Figure 1, after piston rod 6 stretches out and moves to end point of travel toward a direction, because begin contraction drive blade 2 when other direction move when piston rod 6 block 9a that mutually should side makes blade 2 to the obstruction effect of the corresponding tooth bar 3 with it interaction by rack and pinion 4 blade face vertical this moment with the moving direction of piston rod 6, the blade face of blade 2 that is positioned at aluminium liquid bath 1 is perpendicular to the moving direction of piston rod 6, it is mobile toward this moving direction of blade 2 that the blade face of blade 2 promotes aluminium liquid, aluminium liquid is exported this aluminium liquid bath 1 when piston rod 6 contractile motions arrive near end point of travel before, tooth bar 3 is because the barrier effect of the block 9b corresponding with this tooth bar 3 that is subjected to this end, tooth bar 3 forces blade 2 rotations with the interaction of gear 4, when treating that piston rod 6 is contracted to end points and stops, blade 2 has rotated 90 degree, as shown in Figure 2.This moment, the blade face of blade 2 was parallel to the direction that primary aluminum liquid flows.After this when piston rod 6 drive blades 2 back do to stretch out motion, because the blade face of blade 2 is parallel to the direction that primary aluminum liquid flows, therefore aluminium liquid is not flowed when the blade sheet of blade 2 streamline sections returns and produce disturbance when piston rod 6 stretches out motion near the end points of stroke, with in like manner above-mentioned, because of block 9a forces blade to turn 90 degrees for 2 times again to return back to direction that its blade face flows perpendicular to primary aluminum liquid like this to the barrier effect of tooth bar 3, as long as piston rod 6 repeats above-mentioned to-and-fro motion, can reach the purpose that the aluminium liquid of aluminium liquid bath 1 is carried by blade 2.
