Abstract
The utility model discloses a sealing device for a sinter machine trolley, which mainly comprises a sealing groove (1), a free plate (2) and a fixing slide plate (3), etc. The device is characterized in that: the sealing groove (1) is fixedly arranged with an upper holddown plate (4) and a sealing gasket (7), the free plate (2) is fixedly arranged with a lower holddown plate (5) and a sealing gasket (6), both ends of the upper holddown plate (4) and the lower holddown plate (5) are equipped with arc metallic pieces (8,9), which have the clearance with both sides of the sealing groove (1). The utility model is a sealing device for sinter machine trolley with excellent sealing effect, high reliability, easy operation, and high exchangeability.
Description
Technical field
The utility model relates to a kind of sintering pallet, particularly relates to a kind of sintering pallet sealing device.
Background technology
In the sintering deposit production process, be layered on compound (containing all kinds of iron powders, coke blacking etc.) on the sintering pallet through igniter, in the ignition of sinter mixture top layer, the main exhauster exhausting, produce negative pressure in the bellows below sintering pallet, air passes the mixing bed of material on the chassis under the effect of negative pressure, enter bellows, help the burning of carbon dust in the compound into, produce high temperature, making the material that the mixes up clinkering of burning become the sintering lump ore, broken laggard blast furnace ironmaking from top to bottom.But in sintering process, there is 50～60% air quantity to enter bellows, sintering process is not played combustion-supporting effect, but the gap between sintering pallet and bellows (because of sealing the gap of improper generation) directly enters bellows without mixing the bed of material.This class air quantity be referred to as to leak out (inleakage is referred to as air leak rate of air curtain with the ratio of air exhauster exhausting air quantity).Owing to leak out without the compound bed of material, burning is not worked to compound, thereby the burning velocity of compound is reduced relatively, makes the output of sintering deposit influenced, and the cost of sintering deposit is increased relatively.Therefore reduce air leak rate of air curtain, become a big problem of the tool potentiality of the industry already.
The personage knows in the industry, sintering machine in process of production, the position that occurs leaking out is more.But the place of inleakage maximum is still in the sintering machine both sides.Because the length of the both sides section of leaking out several 10 meters to more than 100 meters, (because of the sintering machine specification different) utmost point that leaks out that therefore reduces the sintering machine both sides closes important.
The utility model content
Technical problem to be solved in the utility model provides a kind of good sealing effect, reliable sintering pallet sealing device.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of sintering pallet sealing device, mainly comprise seal groove, trip plate and fixed glides etc., in described seal groove, be fixed with top board and sealing gasket, on described trip plate, be fixed with lower platen and sealing gasket, between described top board and lower platen two ends, be provided with arc metal plate, and leave the gap between described arc metal plate and the described seal groove both sides.
As a kind of improvement of the present utility model, be provided with a sealing oil groove on described fixed glides surface at least along its direction of motion, help reducing leaking out between trip plate and the fixed glides.
Sintering pallet adopts the sealing device of technique scheme, arc metal plate and top board, lower platen just fully shutoff the path clearance that leaks out, prevent to leak out at tens meters length direction from both sides short circuit inlet box.Arc metal plate can also produce counterpressure to the trip plate simultaneously, helps the trip plate to be fixed slide plate, reduces leaking out between trip plate and the fixed glides.The arcuate shape that arc metal plate changes voluntarily satisfies the needs that the trip plate moves up and down.Maximum characteristics of the present utility model are that arc metal plate does not contact with the both sides generation of seal groove in entire work process, do not rub, and have both increased flexibility of the present utility model, have prolonged service life of the present utility model again.
The utility model not only is worth adopting when making new chassis, for the existing equally necessary employing of using of old chassis.The sealing device of the utility model and original old chassis has interchangeability, changes very conveniently, does not need trolley body is made any modification.
In sum, the utility model is a kind of good sealing effect, uses reliable, flexible operation, sintering pallet sealing device that interchangeability is strong.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is that the B-B of Fig. 1 is to cutaway view.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, in described seal groove 1, be fixed with top board 4 and sealing gasket 7 by screw 13,14, on described trip plate 2, be fixed with lower platen 5 and sealing gasket 6 by screw 11,12, between described top board 4 and lower platen 5 two ends, be provided with arc metal plate 8,9, and leave the gap between described arc metal plate 8,9 and described seal groove 1 both sides, be provided with a sealing oil groove 10 along its direction of motion on described fixed glides 3 surfaces.
Arc metal plate 8,9 and top board 4, lower platen 5 complete shutoff the path clearance that leaks out, prevent to leak out at tens meters length direction from both sides short circuit inlet box.Arc metal plate 8,9 can also produce counterpressure to trip plate 2 simultaneously, helps trip plate 2 to be fixed slide plate 3, reduces leaking out between trip plate 2 and the fixed glides 3.The elastic deformation energy of arc metal plate 8,9 satisfies the needs that trip plate 2 moves up and down.Maximum characteristics of the present utility model are that arc metal plate 8,9 does not contact with the both sides generation of seal groove 1 in entire work process, do not rub, and have both increased flexibility of the present utility model, have prolonged service life of the present utility model again.Be provided with sealing oil groove 10 on described fixed glides 3 surfaces along its direction of motion, can effectively seal and reduce leaking out between trip plate 2 and the fixed glides 3, make lubricant effect better simultaneously.
Claims (2)
1, a kind of sintering pallet sealing device, mainly comprise seal groove (1), trip plate (2) and fixed glides (3) etc., it is characterized in that: in described seal groove (1), be fixed with top board (4) and sealing gasket (7), on described trip plate (2), be fixed with lower platen (5) and sealing gasket (6), between described top board (4) and lower platen (5) two ends, be provided with arc metal plate (8,9), and leave the gap between described arc metal plate (8,9) and described seal groove (1) both sides.
