Abstract
The utility model discloses a sealing device for the lower portion of a circular cooler trolley. The sealing device for the lower portion of the circular cooler trolley comprises a sealing fixing plate which is installed on the top portion of an air bellow and a static sealing matching plate which is installed on a movement sealing plate installed at the bottom of the trolley. The sealing fixing plate and the static sealing matching plate are arranged vertically in parallel. A first static sealing surface is arranged on the inner side between the sealing fixing plate and the static sealing matching plate. A second static sealing surface is arranged on the outer side between the sealing fixing plate and the static sealing matching plate. An air-tight air seal space is formed between the first static sealing surface and the second static sealing surface. Compared with the prior art, the sealing device for the lower portion of the circular cooler trolley has the advantages that two static seals are applied to replacing the original one static seal and cold air blast is filled into air seal space, wherein the tension of the cold air blast is higher than the tension in the air bellow. The air leak situation is greatly avoided by applying the three effective sealing methods simultaneously. Due to the fact that the hot air blown into the air bellow is in about 140 degrees after waste heat recovery is applied, the lifetime of sealing rubber used originally is greatly reduced.
Description
Technical field
The utility model relates to a kind of central cooler equipment, specifically upper sealer of trolley for circular refrigerator.
Background technology
In steel manufacture process, the energy consumption of sintering circuit accounts for 10% of total energy consumption, is only second to Iron-smelting, occupies second.In the sintering circuit total energy consumption, there is nearly 50% heat energy to enter atmosphere with the sensible heat form of sintering device flue gas and cooling machine waste gas.
For the call of respective country energy-saving and emission-reduction, the fume afterheat of sintering circular-cooler is recycled.The Sealing Technology of central cooler has influence on the effect that the fume afterheat of central cooler is recycled, and upper sealer of trolley for circular refrigerator has accounted for very consequence in the Sealing Technology of whole central cooler.
Central cooler is the equipment of a continuous motion, in the course of work of central cooler, bellows 15 are fixed, chassis 12 is continuous motions, chassis 12 moves along circular orbit, air blast blasts air in bellows, air passes the heat sinter on chassis 12 bottoms and the chassis 12, heat sinter is cooled to below 150 ℃, because the relative motion that bellows 15 and chassis are 12, just must seal to prevent inside and outside differential pressure and leaking out of causing between top chassis 12 and the lower bellows 15, affect the central cooler cooling effect.But central cooler is not workpiece, central cooler existence in service is to the situation of each different plaies, thereby so that sealing just becomes a bottleneck, originally the hermetically-sealed construction of chassis bottom is seen Fig. 1, the fixing seal body is installed on the beam channel of bellows 15, motion seal 1 is installed in the trolley breast plate bottom, fixing seal body 2 is provided with stationary seal face, stationary seal face is made of the inclined-plane of a cone body, be equiped with the motion rubber gasket sheet of rectangular configuration on the motion seal 1, the motion rubber gasket sheet contacts with stationary seal face, forms inner seal.After the central cooler UTILIZATION OF VESIDUAL HEAT IN, the wind-warm syndrome that blasts in the bellows becomes hot blast about 140 ℃ by original normal temperature, because rubber gasket sheet is applicable to the cooling air of normal temperature, after operation a period of time, this rubber gasket sheet deliquescing and becoming fragile, so that the sealing of these twice just like illusory, causes the air leak rate of air curtain of central cooler to reach 20%～25%, even higher.Greatly affect cooling effect and the UTILIZATION OF VESIDUAL HEAT IN efficient of central cooler.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and reduce that air leaks outside, improves waste heat recovery efficient between circular cooler trolley bottom and bellows, is convenient to make the upper sealer of trolley for circular refrigerator with installation, long service life.
The purpose of this utility model is come specific implementation by the following technical programs:
Upper sealer of trolley for circular refrigerator, comprise the static seal matching board on the sealing fixed head that is installed in the bellows top and the motion sealing plate that is installed in pallet bottom, described sealing fixed head and static seal matching board are corresponding and be parallel to each other up and down, inboard between described sealing fixed head and static seal matching board is provided with the first static seal face, the outside is provided with the second static seal face, forms airtight sealing gland space between the first static seal face and the second static seal face.
The static seal matching board is installed in the below of the former movable sealing contact-making surface that suits mutually with outside static seal in chassis below, for this contact-making surface is widened.
Further, described sealing fixed head is installed in fixedly key seat top.
Described the first static seal face is an inner spring stainless steel diaphragm seal, the inner spring stainless steel substrates comprises bottom and sealing the fixed head vertical plane that is connected and the horizontal plane that top is connected with the static seal matching board, has flexible arc transiting surface between vertical plane and horizontal plane.
Described inner spring stainless steel substrates be fixed on the inner spring stainless steel diaphragm seal fixed head of sealing on the fixed head and be connected by bolt seal.
Described the second static seal face is an outer spring stainless steel diaphragm seal, and be oppositely arranged with the first static seal face, the outer spring stainless steel substrates comprises bottom and sealing the fixed head vertical plane that is connected and the horizontal plane that top is connected with the static seal matching board, has flexible arc transiting surface between vertical plane and horizontal plane.
Described outer spring stainless steel substrates be fixed on the outer spring stainless steel diaphragm seal fixed head of sealing on the fixed head and be connected by bolt seal.
The arc transiting surface of inner spring stainless steel diaphragm seal is identical with the radian of the arc transiting surface of outer spring stainless steel diaphragm seal, utilizes the elasticity of two arc transiting surfaces can absorb up and down play of chassis, realizes preventing the up and down effect of play.
The bottom of described sealing fixed head is provided with several cold wind access tubes that is evenly arranged, and described cold wind access tube is communicated with described sealing gland space.Utilize the cold wind access tube in the sealing gland space, constantly to pass into than the high air of cooling air pressure in the bellows, form together effectively sealing gland.
Because this adopts 2 road static seals, with the static seal matching board widen and static seal between contact-making surface can effectively alleviate since chassis when moving about leaking out of causing of play.
Compared with prior art, the advantage of this novel practical is: adopt 2 road static seals to substitute original 1 road static seal, and be filled with the cold wind higher than bellows internal pressure in the sealing gland space, these 3 effective seal means are implemented simultaneously, have greatly improved the scene of leaking out of circular cooler trolley bottom.After waste heat recovery is implemented, because what blast in the bellows is hot blast about 140 ℃, the life-span of the caulking gum of former employing reduces under such condition of work greatly, adopt the diaphragm seal of stainless steel, guarantee the long-term stability operation under this condition of work, reduced the maintenance workload to sealing.
