Abstract
The invention discloses a special anti-dust device for a crust breaking cylinder, and belongs to the technical field of dustproof protection of an electrolytic aluminum crust breaking cylinder. According to the special anti-dust device for the crust breaking cylinder, a dustproof structure is arranged between a piston rod and a cylinder cover, the dustproof structure comprises a seal ring and a dustproof ring, the seal ring is arranged on the outer side of the dustproof ring, the inner side of the dustproof ring is provided with a zigzag structure matched with the piston rod in outer diameter, and a pressure hole is formed between an inner cavity of the cylinder and an installing groove of the dustproof ring. According to the special anti-dust device, mechanical dust scraping and dust blowing through pressure are combined, dust on the piston rod can be effectively removed, wear is reduced, and therefore the service life of the cylinder is prolonged.
Description
Technical field
The present invention relates to a kind of crust breaking cylinder Special dustproof device, belong to the proofing dust and protecting technical field of electrolytic aluminium crust breaking cylinder.
Background technique
Existing electrolytic aluminium crust breaking cylinder is the Special cylinder that electrolytic aluminium factory is used, its function is divided into blanking crust breaking and goes out two kinds of aluminium crust breakings, during use, pressurized air enters cylinder by pipeline and drives tup fast-descending to realize crust breaking, after crust breaking finishes, by controlling selector valve commutation, makes cylinder fast retractile.The dustproof conventional material of existing cylinder is fluorine rubber lip type circle, and in use, the residing ambient temperature of cylinder is 150 ℃ more than degree, and dust is serious, and cylinder movement velocity when crust breaking is fast and be subject to serious lateral impact.Be subject to high temperature, at a high speed, unbalance loading, the impact of the factor such as lubricating condition is bad, seal ring short term failure, affects the normal operation of equipment.And rubber dust-proof dust blowing underpressure, dust blowing effect is bad.
Summary of the invention
In order to overcome problems of the prior art, the invention provides a kind of crust breaking cylinder Special dustproof device.This dust guard should effectively strike off the dust on piston rod, reduces wear, and improves the working life of part.
The technical solution used in the present invention is: a kind of crust breaking cylinder Special dustproof device, between piston rod and cylinder head, be provided with dustproof construction, described dustproof construction comprises seal ring and dust ring, seal ring is arranged on the outside of dust ring, the inner side of dust ring is provided with the zigzag structure matching with piston rod external diameter, between the inner chamber of cylinder and the mounting groove of dust ring, is provided with pressure port.
Described seal ring adopts two rubber o-rings.
The two ends of the external cylindrical surface of described dust ring are respectively provided with a rectangle groove that rubber o-ring is set, and the interior circular hole of dust ring adopts 2-8 unidirectional sawtooth.
The invention has the beneficial effects as follows: this crust breaking cylinder Special dustproof device, between piston rod and cylinder head, be provided with dustproof construction, dustproof construction comprises seal ring and dust ring, seal ring is arranged on the outside of dust ring, the inner side of dust ring is provided with the zigzag structure matching with piston rod external diameter, between the inner chamber of cylinder and the mounting groove of dust ring, is provided with pressure port.This dust guard adopts mechanical dust blowing and pressure drifting dust to combine, and can effectively remove the dust on piston rod, reduces wear, and has improved the working life of cylinder.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further described
Fig. 1 is a kind of structural drawing of crust breaking cylinder Special dustproof device.
Fig. 2 is the structural drawing of dust ring.
In figure: 1, rubber o-ring, 2, dust ring, 2a, unidirectional sawtooth, 2b, rectangle groove, 3, cylinder head, 3a, left pore, 3b, pressure port, 4, cylinder, 5, cylinder end piece, 5a, right pore, 6, piston, 7, piston rod, 8, gland.
Embodiment
Fig. 1,2 shows a kind of structural drawing of crust breaking cylinder Special dustproof device.In figure, between piston rod 7 and cylinder head 3, be provided with dustproof construction, dustproof construction comprises seal ring and dust ring 2, and seal ring adopts two rubber o-rings 1, between the inner chamber of cylinder 4 and the mounting groove of dust ring 2, is provided with pressure port 3b.The two ends of the external cylindrical surface of dust ring 2 are respectively provided with a rectangle groove 2b that rubber o-ring 1 is set, and the interior circular hole of dust ring 2 adopts 6 unidirectional sawtooth 2b that match with piston rod 7 external diameters.
Adopt above-mentioned technological scheme, the installation groove of dust ring 2 leaves pressure port, and while using right pore 5a air inlet, piston rod stretches out, pressure port is without pressure, because dust can not enter in cylinder 4 when piston rod stretches out, thus carry out low pressure dedusting, when left pore 3a air inlet, in piston rod 7 retraction cylinders 4, pressure port cut-in pressure is 0.6MPa, carries out pressure dedusting, and dedusting is thorough.Dust ring 2 adopts special high-abrasive material and adopts saw tooth structure, and sawtooth adopts 6 unidirectional sawtooth, only to a direction dedusting, can discharge a small amount of dust entering when piston rod stretches out, and dust removing effects is obvious.This dust guard has improved the working life of cylinder 4, has extended service cycle, has reduced compressed-air actuated consumption, can reduce energy waste more than 20%.
