The underground is located to vexed pit, the below of shale shaker sets up the feed bin, and the below of feed bin is located to the vibration feeder ware, and the discharge gate setting of vibration feeder ware is at the low side of belt, the end at the belt is installed to the magnetism roller, in the slag of magnetic separation gets into the bed charge storehouse, sets up transmission device between bed charge storehouse and the high -order feed bin, and high -order feed bin is through a plurality of transfer passage and converter entry linkage. The utility model discloses a heat is vexed carries on that the slag is smashed, separation, magnetic separation, drying, get into the converter and recycle, other surplus slags outward transports, can reduce the iron and steel material consume with slag making material cost, reduce the slag volume of transporting outward and to environmental pollution to can balance the converter heat, reduce the slag making material and consume about 5 -membered / ton.
Description
Technical field
The utility model relates to one and relates to smelter slag processing and recycling explained hereafter field.
Background technology
The important process link of smelting is slag making, to be transferred in slag by the harmful element in molten iron remove by slagging process.But must have part metals iron and enter in slag with diffusing particle shape in slagging process, this area is called " bessemer furnace slag ".Traditional bessemer furnace slag processing mode directly transports outward after fetching water in slag field, and carry out strange land crushing-magnetic selection, which treatment scheme is long, broken difficulty is large, and wherein contained metallic iron can not effectively be recycled, and there is huge waste, and running cost is high, contaminate environment in transportation.
Summary of the invention
Technical problem to be solved in the utility model is the defect existed for prior art, provides a kind of magnetic separation particle steel feeding bin short route device, solves bessemer furnace slag and effectively utilizes and the problem of contaminate environment in transportation.
For solving this technical problem, the utility model provides a kind of magnetic separation particle steel feeding bin short route device, comprises vexed pit, vibratory screening apparatus, feed bin, vibratory feeder, belt, magnetic roller, bed material storehouse, high hopper and converter.
Described vexed pit is located at underground, the below of described vibratory screening apparatus arranges feed bin, the below of feed bin is located at by vibratory feeder, the discharge port of vibratory feeder is arranged on the low side of belt, described magnetic roller is arranged on the end of belt, slag through magnetic separation enters in bed material storehouse, arranges transmitting device between bed material storehouse and high hopper, and high hopper is connected with converter entrance through multiple transfer passage.
Described transmitting device is feed belt.
Beneficial effect: first the utility model adopts heat vexedly to carry out slag pulverizing, then be separated slag by screening, waste residue is transported outward, and slag enters belt magnetic separation, again through screening, large slag drops into converter steelmaking as steel scrap, and little slag enters converter by high hopper to carry out slag making and realize recycling, again can balancing converter heat, and steel technology and slag material cost can be reduced, realize site disposal, reduce outward transport slag amount and environmental pollution, and reduce slag material consumption about 5 yuan/ton.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 vexed pit, 2 vibratory screening apparatuss, 3 feed bins, 4 vibratory feeders, 5 belts, 6 magnetic rollers, 7 bed material storehouses, 8 high hoppers, 9 converters.
Embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
The utility model comprises vexed pit 1, vibratory screening apparatus 2, feed bin 3, vibratory feeder 4, belt 5, magnetic roller 6, bed material storehouse 7, high hopper 8 and converter 9.
Described vexed pit 1 is located at underground, and be convenient to transport, heat and moisture preserving is effective.
The below of described vibratory screening apparatus 2 arranges feed bin 3, and the below of feed bin 3 is located at by vibratory feeder 4, and the discharge port of vibratory feeder 4 is arranged on the low side of belt 5, and whole flow process is rationally smooth and easy, reduces turnover, shortened process greatly.
Described magnetic roller 6 is arranged on the end of belt 5, and the slag through magnetic separation enters in bed material storehouse 7.
Between bed material storehouse 7 and high hopper 8, transmitting device is set, realizes the high position transmission of slag.
Described transmitting device is feed belt.
High hopper 8 is connected with converter entrance through multiple transfer passage, realizes magnetic separation particle steel and enters converter Returning utilization.
The algorithm of the utility model magnetic separation particle steel feeding bin short route is as follows:
1) vexed slag: vexed to the bessemer furnace slag of 900 DEG C heat of carrying out fetching water for 10 hours in vexed pit 1, in slag, f-CaO meets water generation calcium hydroxide and produces expansion, impel the efflorescence of slag hardening crack and reach slag sluicing system by expansion shrinkage, bessemer furnace slag is pulverized, realizing slag and be separated with slag;
2) sieve: through overheated vexed after slag sieve through vibratory screening apparatus 2, the slag that particle diameter is greater than 100mm is separated; The slag that particle diameter is less than 100mm falls in feed bin 3;
3) feed: the slag entering particle diameter in feed bin 3 and be less than 100mm is entered vibratory feeder 4, sends into belt 5 by material feeder 4;
4) magnetic separation: carry out magnetic separation by the slag be arranged on magnetic roller 6 pairs of belts 5 of belt 5 end, select suitable magnetic roller 6 to isolate small-particle slag that grade is not less than 40%;
5) airing: through 2 ~ 3 days natural dryings;
6) converter is entered: through the small-particle slag of magnetic separation by high hopper on transmitting device 8, in smelting process, ceaselessly join converter 9 carry out slag making.
Described step 2) in the selected particle diameter slag that is greater than 100mm add in converter 9 as steel scrap is disposable.
The utility model the past is directly fetched water after the converter slag of outward transport first adopt heat vexedly to carry out slag pulverizing by this abbreviated system, then by screening, slag is separated, waste residue is transported outward, slag enters belt magnetic separation, again through screening, the slag that particle diameter is greater than 100mm once drops into converter steelmaking as steel scrap, the slag that particle diameter is less than 100mm enters converter to carry out slag making and realizes recycling, again can balancing converter heat, and steel technology and slag material cost can be reduced, realize site disposal, reduce outward transport slag amount and environmental pollution, and reduce slag material consumption about 5 yuan/ton.
The above-mentioned embodiment of the utility model, just illustrates, is not only, and all changes within the scope of the utility model or in equivalent scope of the present utility model are all surrounded by the utility model.
