Abstract
The utility model discloses a novel air bellow capable of suppressing an edge effect of a trolley of a sintering machine. The technical scheme includes that an air bellow is arranged below the trolley, barriers are arranged inside the air bellow, are close to edges of the trolley, are positioned in edge areas, which are close to barriers of the trolley, of the inside of the air bellow and are parallel to the running direction of the trolley, and gaps are reserved among lower ends of the barriers and side walls of the air bellow. The novel air bellow has the advantages that the barriers are arranged in the edge areas of the air bellow, the quantity of air flowing through edge regions of the trolley of the sintering machine is reduced, and the edge effect of the trolley of the sintering machine is suppressed; and the barriers are parallel to the air inlet direction, short circuit of an air circuit is prevented, the flow rate of airflow at the edges of the trolley is reduced, the quantity of the air flowing in the width direction of the trolley of the sintering machine tends to be balanced, and the air utilization efficiency and the sinter productivity are improved.
Description
Technical field
The utility model relate in the iron and steel metallurgical industry for the production of the agglomerating plant field, particularly a kind of novel bellows that suppress the sintering pallet edge effect.
Background technology
SINTERING PRODUCTION generally adopts the continuous pallettype sintering machine of exhausting mode at present, under the distributing technique of routine, the intake on sintering pallet both sides is often greater than the intake in the middle part of the chassis, so that the charge level air intake is unbalanced, charge level is insufficient to utilizing of effective wind rate, and studying carefully its cause is because there is edge effect.So-called edge noise reduction refers to that leg is on its impact when fluid flows through along the leg place, space that the loose shape object of solid is housed.Material at the sintering pallet edge is comparatively loose, voidage is large, and material shrinks in sintering process with the chassis plate washer and separate the formation side seam, causes in the sintering process edge drag little, thereby the intake that forms the sintering pallet both sides significantly strengthens the edge effect that middle intake is little.Edge effect causes charge level air-flow skewness, and thermal system is unreasonable, and gas permeability is poor, causes the middle part vertical sintering speed to lag behind, and different vertical sintering speeds increases the weight of again the air-flow skewness, causes vicious circle.
The seventies people just recognize the harm of edge effect in the SINTERING PRODUCTION in last century, also are devoted to administer always, have obtained certain effect.But for a long time, still exist comparatively serious edge effect in the SINTERING PRODUCTION, it directly affects Yield and quality and the process energy consumption of sintering deposit.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of air quantity that reduces by the sintering pallet fringe region for the existing problem of above-mentioned prior art, improves the novel bellows of the inhibition sintering pallet edge effect of sintering deposit productivity ratio.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of novel bellows that suppress the sintering pallet edge effect, below chassis, be provided with bellows, be provided with baffle plate near in the bellows at chassis edge, described baffle plate is positioned at bellows near the fringe region of chassis baffle plate, described baffle plate is parallel with the chassis traffic direction, and the lower end of described baffle plate and the sidewall of bellows leave the gap.
By technique scheme, described baffle plate is two, is respectively the first baffle plate, second baffle.
By technique scheme, the degree of depth of establishing described baffle plate is H, and the most antermarginal distance of baffle plate and bellows is L0, H=1 ~ 1.5L0.
By technique scheme, the first baffle plate is 5cm-10cm apart from the bellows Edge Distance, and second baffle is 20cm-35cm apart from the bellows Edge Distance.
The obtained beneficial effect of the utility model is: 1, install baffle plate by the fringe region at bellows, reduce the air quantity by the sintering pallet fringe region, suppress the sintering pallet edge effect, alleviate edge effect to the impact of SINTERING PRODUCTION, improve sinter quality and reduce process energy consumption; 2, baffle plate is parallel with the direction of air intake, prevents path short circuit, has slowed down the flow velocity of chassis edge air-flow, so that air quantity tends to balance more at the sintering pallet width, has improved the utilization ratio of wind, has improved sintering deposit productivity ratio.
Description of drawings
Fig. 1 is the wind speed at sintering pallet edge and the graph of a relation of distance.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the longitudinal section schematic diagram of Fig. 2.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Find after testing, the relation that the wind speed at sintering pallet edge and distance exist as shown in Figure 1, characteristics for the charge level wind speed, be provided with baffle plate at the bellows near the chassis edge, shown in Fig. 2,3, described bellows are the container of truncated rectangular pyramids shape, described baffle plate is arranged on the upper surface of bellows 1 near the fringe region of chassis baffle plate, the two ends, the left and right sides of baffle plate are fixed on the sidewall of bellows, and the upper end flushes with the upper surface of bellows, and the lower end of baffle plate and the sidewall of bellows leave the gap.The setting party of baffle plate is to parallel with the trolley movement direction.Baffled and the most antermarginal distance of bellows are L0, and the degree of depth of baffle plate is H, find through test, and when H=1 ~ 1.5L0, the inhibition of edge effect is the most obvious.
Embodiment 1:
Be provided with in an embodiment two baffle plates, be respectively the first baffle plate 2, second baffle 3, form two wind guide tanks.The first baffle plate is 5cm apart from the most antermarginal distance of bellows, and the degree of depth of the first baffle plate is 5cm, and second baffle is 20cm apart from the most antermarginal distance of bellows, and the degree of depth of second baffle is 20cm.
Embodiment 2:
Substantially the same manner as Example 1, difference is that the first baffle plate is 8cm apart from the most antermarginal distance of bellows, and the degree of depth of the first baffle plate is 10cm, and second baffle is 25cm apart from the most antermarginal distance of bellows, and the degree of depth of second baffle is 30cm.
Embodiment 3:
Substantially the same manner as Example 1, difference is that the first baffle plate is 10cm apart from the most antermarginal distance of bellows, and the degree of depth of the first baffle plate is 15cm, and second baffle is 35cm apart from the most antermarginal distance of bellows, and the degree of depth of second baffle is 52.5cm.
In sum, on the one hand, control the incoming air area of sintering machine fringe region by installing baffle plate and control the edge effect of intake inhibition sintering pallet, on the other hand, by baffle plate is set, slowed down the flow velocity of chassis edge air-flow, so that air quantity tends to balance more at the sintering pallet width, improve the utilization ratio of wind, improved sintering deposit productivity ratio.
