The circular magnetic fluid sealing system greatly improves seal performance of the circular cooler, increases quality of finished pellet ore and utilization rate of hot air, improves field environment, and evidently reduce production cost of enterprises.
Description
Technical field
The utility model relates to the central cooler apparatus field, particularly relates to a kind of central cooler annular magnetic fluid seal system.
Background technology
In the central cooler equipment that metallurgy industry uses, central cooler generally adopts the air blast cooling, cold air produces heat exchange after airtight ring cold machine smoke hood is derived by the red-hot bed of material and high temperature pellet from bottom to top, cooled EGT is 250～340 ℃, even it is higher, this waste gas reclaims after waste heat boiler produces steam, can directly utilize or be used for cogeneration.In order to make the central cooler good seal, hot waste gas does not move the joint effusion of slewing frame and seal closure from central cooler, sealing device need be installed herein.Seal closure is suspended on the central cooler skeleton by suspension arrangement, and has take-up device spacing.Its seal of tradition circular cooler trolley breast board annular seal is a block plate, and steel plate and chassis breast board end face keep gap 5mm at least, because the chassis breast board moves, because of making and installation errors, this gap is difficult for too small in addition.At present, be sealed with two kinds of common forms between annular seal and the chassis breast board: the one, water-stop, annular seal directly is welded on the chassis breast board, because chassis breast board temperature under the influence of high temperature pellet and hot waste gas is very high, because the thermal conductivity of metal is strong,, be easy to generate distortion again so the temperature of annular seal is also very high, this makes the commissure of ring packing cell body easily crack, and the fault of leaking, leaking gas occurs.The 2nd, husky sealing, the sand in the sand seal groove easily blown away by hot blast and husky thermal conductivity factor low, cause that the sand seal plate is at high temperature yielding to make sand outflow in the sand seal groove.Very big gap is also arranged between central cooler bellows and chassis, and to leak out also very serious herein, needs to install sealing device.Traditional sealing device adopts the sealing of thickening rubber slab because rubber slab is a vulnerable part, use a period of time after sealing effectiveness can lose sealing effectiveness worse and worse.
Summary of the invention
In order to overcome problems such as water-stop that prior art exists leaks and the low sand of husky sealing pyroconductivity is blown away, the utility model provides a kind of central cooler annular magnetic fluid seal system, and this utility model has the generation of being difficult for principal fault, waste heat recovery rate height, is convenient to advantages such as installation and manufacturing.
The technical scheme that its technical problem that solves the utility model adopts is: annular magnetic fluid seal apparatus and following annular magnetic fluid seal apparatus are set in the upper and lower of central cooler both sides chassis breast board, the magnet fluid sealing medium is housed in the seal groove of described upper and lower annular magnetic fluid seal apparatus, and an end of each motion dividing plate inserts respectively in the magnet fluid sealing medium of splendid attire in the corresponding seal groove; Symmetrical being placed on of two row's group of magnets forms high-intensity magnetic field in the seal groove, the magnetic fluid medium after being magnetized has very strong pressure-resistant seal performance.
In technique scheme, in the seal groove arranged outside U of reinforcement type gusset is arranged, to improve the strength and stiffness requirement of seal groove, make seal groove firm and solid.
The top of described seal groove all is equipped with the dust protection rubber plate, prevents that effectively impurity from entering in the seal groove, makes magnetizing mediums impurity level in the seal groove raise and influences sealing property.
The manufactured materials of described motion dividing plate is stainless steel, aluminium or plastics.
The beneficial effects of the utility model are: the stationary part of annular magnetic fluid seal apparatus is by being bolted on the bearing under the cold ring machine annular magnetic fluid seal system, and stationary part of annular magnetic fluid seal apparatus is fixed on the central cooler skeleton column by bracing frame on it.And the stationary part of domestic existing hermetically-sealed construction is mounted on the chassis breast board, and the intrinsic weight that this has just reduced the chassis breast board has reduced the load that rotates.Because seal groove and chassis breast board have one section the air gap, so the heat on the chassis breast board has only a part seldom to be delivered on the seal groove, the working environment that this has just improved device for sealing magnetic fluid widely makes sealing effectiveness be promoted.Described central cooler annular magnetic fluid seal apparatus has overcome other sealing medium voltage endurance capability difference and seal member is out of shape and the problem of sealing medium leakage, makes the sealing property of central cooler be greatly improved.The waste gas that reclaims can directly utilize or be used for cogeneration through the steam that waste heat boiler produces.The utility model has improved the utilization rate of pellet product quality and hot blast, has improved in-situ production environment and has made the production cost of enterprise be able to obvious reduction again.
