Abstract
The present invention relates to a non-contact magnetic liquid sealing device between trolley slide and windbox slipway in exhausting system of sintering machine and pellets baking machine. Said device is characterized by that the magnetic suspension with a certain volume is held in the magnetic liquid trough, a sealing baffle made of non-magnetic material is mounted on the trolley body, and the sealing baffles of adjacent two trolleys are mutually overlapped, and the sealing baffle is inserted into magnetic suspension in the magnetic liquid trough by means of internal and external rubber plates, and the magnetic field force produced by magnetic liquid channel under the condition of negative pressure can make the magnetic suspension do not be sucked away by wind so as to implement sealing between trolley of sintering machine and windbox.
Description
The present invention relates to the non-contact type magnetic liquid sealing device between the bogie slide plate and bellows slideway in a kind of sintering machine and the pellet firing machine exhausting system.
At metallurgy industry, agglomerates of sintered pellets production is an important material preparation section.The quality of SINTERING PRODUCTION and efficient directly influence the quality and the output of the pig iron, and the key of decision sintering deposit and pellet quality and manufacturing efficiency is sintering machine and burning machine.At present, producing the sintering machine that uses both at home and abroad, generally adopting various down draft sintering technology, as forms such as disk down draft sintering, belt down draft sinterings.But the sintering machine of above-mentioned form exists the problem of seriously leaking out because the sintering machine of operation can not contact with ground way is fine, not only causes the waste of the energy, and the maintenance difficulty is big, and is limiting the raising of sintering efficient.
The object of the present invention is to provide the contactless magnetic sealing means of a kind of sintering machine, this device is installed in bellows outside low temperature area, it can realize sealing between sintering machine bogie slide plate and the bellows slideway effectively, reduce the energy consumption and the maintenance expense of blower fan, improved the output of sintering machine and the quality of product.
Contactless magnetic sealing means between this sintering machine exhausting system bogie slide plate and the bellows slideway, comprise magnetic liquid bath 7, compositions such as magnetic suspension liquid 8 and sealed baffle 6, it is characterized in that: longitudinal divisions is installed magnetic liquid bath 7 on the channel-section steel 9 of the both sides of sintering machine wind box 10, magnetic liquid bath 7 is made by magnetic material and nonmagnetic substance, the rubber plate that its top has two afterbodys to turn up, the position that outside rubber plate 5 is turned up upwards, the position that inboard rubber plate 12 is turned up is downward, the internal layer of magnetic liquid bath 7 is non magnetic grooves 16, skin is a magnetic groove 13, places magnet 15 between both sides internal layer and the skin; The magnetic suspension liquid 8 of certain volume is housed in the magnetic liquid bath 7; The sealed baffle made from nonmagnetic substance 6 is installed on the trolley body 1, sealed baffle on adjacent two chassis overlaps mutually, sealed baffle 6 inserts in the magnetic suspension liquid 8 of 7 li of magnetic liquid baths by inside and outside rubber plate 12,5, under negative pressure state, the magnetic force that magnetic liquid bath 7 is produced is not siphoned away magnetic suspension liquid 8 by wind, thereby has realized the sealing between sintering pallet and the bellows 10.
Drawings and Examples:
Fig. 1 is the horizontal cross-sectional schematic of non-contact type magnetic liquid sealing device for sintering machine
Fig. 2 is the horizontal cross-sectional schematic of magnetic liquid bath
Accompanying drawing 1 is the disclosed embodiment of the utility model (seeing accompanying drawing 1), and longitudinal divisions is installed magnetic liquid bath 7 on the both sides channel-section steel 9 of conventional sintering machine bellows 10, and the magnetic suspension liquid 8 of certain volume is housed in the magnetic liquid bath 7; The sealed baffle made from nonmagnetic substance 6 is installed on the trolley body 1 of chassis, the sealed baffle of two adjacent chassis overlaps mutually, sealed baffle 6 inserts in the magnetic suspension liquid 8 of 7 li of magnetic liquid baths by inside and outside rubber plate 12,5, forms the sealing system of a sealing.Under negative pressure state, the magnetic force that magnetic liquid bath 7 is produced is not siphoned away magnetic suspension liquid 8 by wind.Thereby realize the sealing between sintering pallet and the bellows 10.
