Abstract
The invention relates to a side sealing device between a trolley and an air box in a sintering production line. The side sealing device comprises wind shielding frames respectively fixed on the two sides of the bottom of the trolley and sealing strips respectively fixed to the two sides of the top of the air box, wherein the sealing strips are made of an elastic material; the upper parts of the sealing strips are adhered to the inner side faces of the wind shielding frames. Sealing is realized by adopting the manner that the sealing strips made of the elastic material are adhered to the cambered surfaces of the wind shielding frames, so that reliable sealing is realized. The sealing strips made of the elastic material are not directly mounted on the trolley, and a thermal insulation material is arranged in the wind shielding frames, so that the temperature of the sealing strips is greatly reduced, the temperature resistance requirement of the sealing strips can be reduced, and the cost is reduced. Moreover, the sealing strips are connected to the top of the air box through a base plate and screws, so that the side sealing device is convenient to mount and can also be simple and convenient to disassemble when the sealing strips need to be changed.

In iron and steel is produced, SINTERING PRODUCTION is one of important operation, and it provides the raw material of high-quality for blast furnace ironmaking.In existing sintering system, sintering pallet is positioned at above sintering machine wind box, run on the trolley track of bellows both sides after sintering pallet being filled compound, light a fire at compound top through ignition furnace, bellows are at sintering pallet downdraft, compound is sintered downwards by the top of sintering pallet, in order to the exhausting effect making bellows reach good, must ensure there is reliable sealing between sintering machine wind box and sintering pallet, it is the least possible not produce leaking out of leaking out or produce.Reducing that sintering leaks out is Focal point and difficult point in sintering process design and production maintenance, owing to there is gap between chassis and chassis and between chassis and bellows, leak out serious, even reach more than 50%, not only waste energy, form noise pollution environment, and limit the raising of SINTERING PRODUCTION efficiency and affect product quality.
China Patent No. is the side-sealing device that the patent of invention of ZL 201110129977.X discloses between a kind of sintering pallet and bellows, installing rack is positioned at inside bogie wheels and is installed with windbreak, windbreak is positioned at bellows top, has gap between windbreak and sintering pallet bottom.Bottom the trolley body of sintering pallet, be provided with the sealing plate longitudinally arranged, the length of sealing plate is the length of a sintering pallet, and the sealing plate at least medial surface of middle and lower part contacts with the lateral surface of windbreak simultaneously.Side seal is realized by the contact of sealing plate and windbreak.The shortcoming of above-mentioned side-sealing device is: 1, sealing plate is for leaning against on windbreak, by the impact of machining accuracy, can not realize reliable sealing between sealing plate and windbreak; 2, the trolley body temperature due to pallet is very high, so require that sealing plate is that exotic material is made, manufacturing cost is very high; 3, at bellows top fixed installation windbreak, complicated operation.
Summary of the invention
First technical problem to be solved by this invention is: provide a kind of side-sealing device that can ensure in the sintered production line of sealing reliably between chassis and bellows.
For solving the problem, the technical solution used in the present invention is: the side-sealing device in sintered production line between chassis and bellows, comprise the windshield frame being separately fixed at pallet bottom both sides and the sealing strip being separately fixed at both sides, bellows top, described sealing strip is made up of elastomeric material, and the medial surface of the top of sealing strip and windshield frame fits.
The medial surface of described windshield frame is outwardly arcwall face.
Second technical problem to be solved by this invention is: provide the side-sealing device between chassis and bellows in the sintered production line that a kind of manufacturing cost is lower.
For solving the problem, the technical solution used in the present invention is: described windshield frame is the closed structure of hollow, and its inside is filled with heat-barrier material.
3rd technical problem to be solved by this invention is: provide the side-sealing device between chassis and bellows in a kind of sintered production line easy for installation.
For solving the problem, the technical solution used in the present invention is: the syndeton between described sealing strip and bellows is: both sides, bellows top are respectively arranged with side seal plate, sealing strip is arranged on above side seal plate, and is fixed with bellows through after side seal plate by screw.
Described side seal plate extends along the both sides of bellows, be spliced by some sections, syndeton between adjacent side seal plate is: one end of every section of side seal plate is provided with downward hook portion, the other end is provided with hook portion upwards, two hook portions cooperatively interact, and upon connection, the upper surface of sides adjacent sealing plate keeps concordant with lower surface.
The invention has the beneficial effects as follows: the side-sealing device in above-mentioned sintered production line between chassis and bellows, its mode adopting the cambered surface of sealing strip and the windshield frame be made up of elastomeric material to fit realizes sealing, and achieves reliable sealing.The sealing strip be made up of elastomeric material due to it is not directly installed on chassis, and is provided with heat-barrier material in windshield frame, and the temperature suffered by sealing strip is reduced greatly, thus can reduce the heatproof requirement to sealing strip, reduces cost.In addition, its sealing strip is connected with bellows top by base plate and screw, not only easy for installation, and also can easyly dismantle when sealing strip changed by needs.
