Description
Technical field
The present invention relates to the beginning and the end sealing technical field of sintering machine, particularly a kind of air-cell type profiling sealing device of sintering machine.
Background technology
The height of sintering machine air leak rate of air curtain directly influences output, quality and the cost of sintering deposit, and the sintering industry is all striving to find the method that reduces air leak rate of air curtain both at home and abroad.The kind of sintering machine seal form has two kinds, and one is static seal, and it can solve by strengthening management, safeguarding.Another is movable sealing, and it must be flexible, a reliable mechanism.
First closes end envelope, second on behalf of spring seals on behalf of four rod hinge connection Weight type ends, and the hinged Weight type end envelope of third generation lever.The forms of four connecting rods of the many employings of sintering machine the beginning and the end sealing at present, its major defect is: the one, it is higher that required precision is put in manufacturing and installation, otherwise influence the flexibility of its sealing device; The 2nd, cover plate can only translation, and the chassis bottom surface can not be a plane, can not comprehensively seal chassis; The 3rd, can not comprehensive engagement owing to acquire plate and chassis bottom surface, cause the pressure increase on the unit are, this will accelerate the wearing and tearing of chassis bottom surface and cover plate; The 4th, leaking out of initial and end causes initial and end bellows negative pressure to reduce, and influences sintering quality and output.
Chinese patent 200420032389.X provides a kind of motion sintering machine the beginning and the end sealing device flexibly, mainly form by upper cover plate, support link mechanism and ash bucket etc., every upper cover plate is all supported by separately movable spacing cramp bar and movable sealing cramp bar, the centre of two cramp bars flexibly connects with fixed support separately, one end rolls with the bottom surface of upper cover plate and contacts, the other end is connected with falling part, is provided with spacing rigid seal plate between ash bucket and head or tail bellows.Two cramp bars of the present invention and upper cover plate are kinematic pair, and spacing rigid seal plate and lap seal plate etc. have constituted two seals, though this device good seal performance, the wearing and tearing of cover plate and chassis are less, but it need have a cover hydraulic system supporting with it, and structure is complicated, and cost is relatively also high.
Summary of the invention
The purpose of this invention is to provide a kind of motion flexibly, reliably, good sealing effect, structure is simple relatively, the air-cell type profiling sealing device of sintering machine that easy access is safeguarded.
The present invention realizes by following technical proposals:
Air-cell type profiling sealing device of sintering machine of the present invention; it is characterized in that comprising heat-resistant wear-resistant lining board; be arranged on the elastic bag protection casing of heat-resistant wear-resistant lining board bottom and be arranged on interior elastic bag and the elastic bag carriage of elastic bag protection casing; fixedly connected with the sintering machine frame in described elastic bag protection lower box two ends; spring adjusting device is fixed on the bottom of elastic bag protection casing by screw; bottom at described elastic bag protection casing is provided with air inlet; a buffer air bag is also established in the outside at described elastic bag protection casing, and this buffer air bag is connected by the air inlet of loading line with elastic bag protection bottom half.
Described heat-resistant wear-resistant lining board of the present invention is the multisection type heat-resistant wear-resistant lining board, adopts inserted each other connection between the adjacent heat-resistant wear-resistant lining board, and every heat-resistant wear-resistant lining board is with dormant bolt and blind threaded connection above the elastic bag.
The described all-metal construction of using of the present invention; be welded to each other by six heat-resisting elastic metallic materials and form; be designed to snakelike curved surface spring steel plate structure with the two sides of forward and backward elastic bag that is abutted against mutually of elastic bag protection casing, all the other left and right and above and below are the plane elasticity steel plate.
Spring adjusting device of the present invention by spring housing, be arranged on the spring in this spring housing and regulate bolt and formed, and the spring top in the spring housing contacts bottom the elastic bag carriage and is connected.
The present invention compared with prior art has brand-new hermetically-sealed construction.It is applicable to the flat seal under the adverse circumstances such as high temperature, dust are big and the curved surface sealing of variation.Have following six aspect characteristics:
1, goes up between the movable sealing face of plane the curved surface sealing of the profiling formula that can realize fitting continuously.Overcome between the sealing surface of prior art end envelope,, realized the long distance sealing in no gap substantially because of the problem of leaking out of segmentation translation formation staged curve-seal form.
2, side elevation sealing is cancelled first three for all areas that leak out that form because of whole segmentation action sealing of end envelope by new construction.Improve the seal operation efficient of end envelope greatly.
3, this gasbag-type is fitted to seal and can be satisfied the movable sealing face of going up simultaneously at width and vertical, the seal request that the curved surface of both direction and plane change.
4, sealing ash collection slot and ash discharge closed conduit in the existing sealing device have been cancelled.Reduced and leaked out a little, simplified the end seal structure, alleviated the weight of equipment of end envelope.
5, sealing load be can realize arbitrarily adjusting by peripheral hardware charging valve and charging connector and hermetic resistance and constant sealing load reduced.Can realize the variation of whole height by the height of adjusting support spring.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
As shown in Figure 1; air-cell type profiling sealing device of sintering machine of the present invention; comprise heat-resistant wear-resistant lining board 2; be arranged on the elastic bag protection casing 1 and the elastic bag 3 and the elastic bag carriage 4 that are arranged in the elastic bag protection casing 1 of heat-resistant wear-resistant lining board 2 bottoms; fixedly connected with the sintering machine frame in described elastic bag protection two ends, casing 1 bottom; spring adjusting device is fixed on the bottom of elastic bag protection casing 1 by screw 5; bottom at described elastic bag protection casing 1 is provided with air inlet; in order to make sealing surface when being out of shape, the unnecessary gas in the elastic bag be shifted and deposit; the present invention also establishes a buffer air bag 12 in the outside of described elastic bag protection casing 1; this buffer air bag 12 is connected by the air inlet of loading line 11 with elastic bag protection bottom half; and on loading line, be provided with Pressure gauge 13 and vent valve 14, invariable to guarantee sealing load.
