Abstract
The utility model discloses a forward stepped material pad funnel belonging to a transition structural member in a raw material conveying system. The forward stepped material pad funnel comprises a material facing device arranged relative to a belt conveyor driving wheel and a stepped material pad arranged below the belt conveyor driving wheel, wherein an inclined cylinder for forming a material channel is defined by the underside of the material facing device and the stepped material pad, and the longitudinal section of the material facing device is L-shaped. Compared with the prior art, the forward stepped material pad funnel has the beneficial effects that the material falling channel is inclined and is consistent with the operation direction of the belt conveyor driving wheel, so that the impact of materials to the funnel and a downstream belt is reduced, meanwhile, the service periods of the funnel and the downstream belt are prolonged, and the equipment maintenance quantity is reduced; moreover, due to the arrangement of the structure, the material crushing degree is reduced, the particle size of the materials is stabilized, and the quality of crude fuel of a blast furnace is favorably improved.
Description
Technical field
The utility model belongs to the excessive framing member in transporting system for raw materials, refers to particularly mutually be connected between a kind of belt transporter the forward notch cuttype gasket-type funnel especially using in blast furnace sinter ore deposit and returning charge transportation.
Background technology
Funnel is the transition structure part being mutually connected between belt transporter, and its arrangement form is generally divided into three kinds: one is the straight line linking of 180 °, and two is vertical linkings of 90 °, and three is oblique line linkings of 30 °～60 °.Three kinds of arrangement form cathetuss are connected the most common with vertical linking.The structure of funnel is steel structure casing normally, and its inside is by anti abrasive liner plate place mat, the shape side of being mainly taper (transport particles and lump material) and conical (transportation granular material).The funnel that blast furnace crude fuel transport point is used is all generally the square conical hopper of cutting mode of directly falling, its structure and principle of work are as shown in Fig. 1 of Figure of description part: under the belt 4 that material 1 drives at belt feeder power wheel 2 drives, in belt feeder power wheel 2 ends, fall, through directly falling funnel 3, drop on the belt 4 in downstream, under tail pulley of belt conveyor 6 drives, along material movement direction 5, transport.There is following defect in this funnel:
1, rewinding function is poor: material 1 directly impacts downstream belt 4 and disperses not to be concentrated, can not equalization stable in belt 4 line of centers both sides, and easily cause downstream belt 4 sideslip faults;
2, affect downstream conveyor belt 4: material 1 directly impacts downstream belt 4 and easily causes driving surface wearing and tearing aggravation, significantly reduced by 4 service lifes of belt;
3, reduce material performance: material 1 directly impacts the fragmentation that downstream belt 4 easily causes material 1, has reduced raw material granularity, affected and smelted the requirement to raw material granularity;
4, plant maintenance amount, material 1 waste and pollute large: 1 pair of material directly falls the impact of funnel 3 and friction and easily reduces this funnel service life, has increased plant maintenance amount; Meanwhile, the breakage of funnel can cause material 1 to leak, and causes the wasting of resources and affects the clean of production environment.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of forward notch cuttype gasket-type funnel, can effectively change and descent path and the landing point of stable material, and then improve operating rate and the service life of funnel.
For solving the problems of the technologies described above, a kind of forward notch cuttype gasket-type funnel that the utility model provides, comprise with belt feeder power wheel is oppositely arranged and meet materials device and be arranged at the notch cuttype backing strap of belt feeder power wheel below, meet the tubular that encloses inclination between materials device below and notch cuttype backing strap, form the passage of material; Described vertical section of meeting materials device is L-shaped.
In technique scheme, described in meet the horizontal segment end of materials device and every one-level step outer end of notch cuttype backing strap is respectively equipped with striker plate.
In technique scheme, the step bottom of described notch cuttype backing strap is provided with rewinding plate, and described rewinding plate is the trapezoidal of lower bottom opening.
Compared with prior art, the beneficial effects of the utility model are: the passage that material falls tilts and be consistent with belt feeder power wheel service direction, alleviated the impact of material to funnel and downstream belt, extended the operating cycles of funnel and downstream belt simultaneously, reduced plant maintenance amount, and this structure setting has also reduced the degree of crushing of material, has stablized raw meal particle size, be conducive to the quality of blast furnace crude fuel.

The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in further detail:
Fig. 1 has illustrated existing structure and the principle of work that directly falls funnel, because being described in detail in background technology part, in this, repeats no more.
As shown in Figures 2 to 4, a kind of forward notch cuttype gasket-type funnel of the present utility model, comprises with belt feeder power wheel 2 is oppositely arranged and meets materials device 7 and be arranged at the notch cuttype backing strap 9 of belt feeder power wheel 2 belows.The vertical section of meeting materials device 7 is L-shaped, encloses the tubular of inclination between its below and notch cuttype backing strap 9, forms the passage of material 1, and passage bottom forms discharge spout 11.
During use, under driving, the belt 4 that material 1 drives at belt feeder power wheel 2 falls in belt feeder power wheel 2 ends, can first meet the dead bed of material 13 that forms approximately 45 °, inclination angle on every one-level step of materials device 7 and notch cuttype backing strap 9, the surface of all dead bed of material 13 forms the liner plate place mat of charge level 12 replacement conventional funnel inside under funnel.The form of this " material dnockout " has been avoided the direct impact of 1 pair of funnel of material itself and downstream belt 4, and has reduced material 1 falling speed, the period of inspection and repair of having improved funnel, has extended service life of downstream belt 4.
As preferred embodiment, in the present embodiment, meeting the horizontal segment end of materials device 7 and every one-level step outer end of notch cuttype backing strap 9 is also respectively equipped with striker plate 8, be more conducive to the formation of the dead bed of material 13 and stable, also can prevent that in ladders at different levels, gall angle.
Another preferred embodiment, to be provided with rewinding plate 10 on the step bottom of notch cuttype backing strap 9, this rewinding plate 10 is the trapezoidal of lower bottom opening, thereby changes the sense of motion of material 1, and material 1 is drawn in and is guided to discharge spout 11 centers near the belt theoretical centerline 15 of downstream belt 4.
