Abstract

The utility model relates to a cylinder batching device capable of homogeneously distributing the material, belonging to the field of material conveying and donation technology. The technical problem to be solved is to provide a cylinder batching device capable of homogeneously distributing the material to overcome the uneven batching flaw of the prior art. The utility model comprises a cylinder, a guide board, a feed hopper and a rack. The improvement lies in that the width of the guide board is bigger than the length of the cylinder; the lower section of the guide board is of cone-shape, and the cone-shape port width is corresponding with the batching width; the guide board surface takes in silent shape and the two ends of the guide board are respectively provided with bafflers. When in use, the material flow width is gradually increased, which is easy to get the required batching width; the material is able to sub-flow toward the two sides when flowing on the guide board. The batching layer is free from the flaws of large particle at the two edges and loose and air leakage, which overcomes the faults of decrease of the sintering negative pressure, fast sintering speed at the two edges, and high burning rate at the trolley sideboard, thereby being suitable for the cylinder batching device, in particular to the cylinder batching device of the metallurgy sintering machine.

Description

But the muslin tubing materials device of uniform distribution

Technical field

The utility model relates to the muslin tubing materials device, and especially metallurgy industry sintering machine muslin tubing materials device belongs to mass transport charity technical field.

Background technology

The iron making and sintering machine is made of cylinder, guide plate, feed hopper etc. with the muslin tubing materials device, feed hopper is positioned at above the cylinder, the guide plate tiltably-mounted is below cylinder, when cylinder rotates under transmission mechanism drives, the material of feed hopper input flows to guide plate along drum surface, flows to the chassis of accepting cloth along the inclined plate surface of guide plate.Above-mentioned muslin tubing materials device is on structural design, and the length of cylinder is less than the chassis width, and the width of guide plate is less than drum length, and guide plate is a slab construction, and the distribution device of this kind structure has following problems when using:

1. material is along the flowing in the process of cylinder, guide plate, and the width that flows dwindles gradually, and the cloth width when flowing to chassis is less than the chassis width, and material is discontented in shop, position, chassis both sides of the edge, and the shop is uneven, it is unreal to press;

2. dwindle gradually owing to the materials flow width, the larger particles material is easy to tumble naturally along stockpile the marginal position of pallet bottom both sides, appearance institute bed of cloth middle part granularity is little, the bed of material is fine and close, the phenomenon that position, both sides particle is big, the bed of material is loose, during sintering, middle tight section is difficult for grilling thoroughly, both sides porous spot then sintering velocity is too fast, and formation is leaked out in " air channel " herein, and the sintering negative pressure is reduced, and influences sintering quality and productivity of sinter;

3. both sides porous spot sintering temperature height causes the chassis breast board burn out rate that is in this position to rise, and frequent breakage change breast board and cause frequent shutdown, and maintenance load is big, and the spare part expense increases.

For a long time, the use defective of said structure distribution device perplexs the ordinary production of sintering machine always, presses for solution.

Summary of the invention

But technical problem to be solved in the utility model provides a kind of muslin tubing materials device of uniform distribution, to overcome the defective that exists in the above-mentioned prior art.

Technological improvement plan of the present utility model is:

But a kind of muslin tubing materials device of uniform distribution, its composition comprises cylinder, guide plate, feed hopper and frame, its improvement is, the width L2 of described guide plate 2 is greater than the length L 1 of cylinder 1, the guide plate lower end is taper, the corresponding cloth width of bell width L, the plate face of guide plate is convex, and the guide plate both sides are respectively equipped with baffle plate 3.

But the muslin tubing materials device of above-mentioned uniform distribution, the length of described cylinder 1 is greater than cloth width L;

But the muslin tubing materials device of above-mentioned uniform distribution, the cone height of described guide plate lower end is 1/3 of a guide plate height, described guide plate height of projection is 10～20MM.

The utlity model has following improvement effect:

1. adopting the guide plate width is the structural design of taper, both sides band baffle plate greater than cylinder width, guide plate outlet, and the width of materials flow is become by original dwindling gradually and widens gradually, is easy to obtain required materials flow width, makes materials flow be paved with whole pallet bottom;

2. adopt the plate face structure of evagination and baffled in both sides, when flowing on guide plate, can shunt to both sides smoothly material, and flow in the middle of the both sides flow is a bit larger tham, the material that flows to both sides is when the baffle plate that is subjected to both sides stops, coarsegrain material drop point is away from the cloth widthwise edges, the small grain size material is then pasting baffle plate and is wandering at cloth widthwise edges place, institute's bed of cloth, granularity big, loose defective of leaking out in position, no both sides of the edge has overcome the reduction of sintering negative pressure, sintering quality and the affected defective of productivity ratio that cause thus;

3. because the partly loose air leakage phenomena of bed of cloth non-flanged so overcome the defective that edge's sintering velocity is fast, temperature is high, effectively reduces the burn out rate of chassis breast board, reduced machine halt trouble, reduced maintenance load and spare part loss because of the breast board scaling loss.

The utility model is suitable on the muslin tubing materials device, adopts on the particularly metallurgy sintered machine muslin tubing materials device.

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the guide plate sectional view.

The specific embodiment

Consult Fig. 1,2,3, be illustrated as and be used for sintering pallet distribution device embodiment.Among the figure, cylinder 1 swivel bearing is on frame 4, guide plate 2 tilts to be fixed on the frame 4, feed hopper 5 is positioned at the cylinder top, cloth width L is the width between on chassis two breast boards, the length L 1 of cylinder 1 is greater than cloth width L, the width L2 of guide plate 2 is greater than the length L 1 of cylinder, and the lower end of guide plate 2 is taper, the corresponding cloth width of bell width, its width value is slightly smaller than breast board upper end spacing, the plate face of guide plate is the arcuation to outer lug, and the baffle plate 3 and the guide plate of guide plate both sides can be whole syndeton, but also split connects, adopt in the illustrated embodiment and divide attachment structure, the height of baffle plate is decided on mass flow.The cone height of guide plate lower end is 1/3 of a guide plate height, and the difference in height at guide plate intermediate projections circular arc position and position, both sides is 15MM.
