Utility model content
The purpose of this utility model is to provide the straight feeding device of a kind of sintering deposit, it can solve sintering deposit conveying and exist transfer point many, the storage time is long and the high sintering deposit that causes of drop is cracked, roll up fine granularity, cause permeability of stock column variation in stove, affect blast furnace stable smooth operation, increase considerably the problem that return mine transfer cost and the treating cost of returning mine cause productive costs to increase.
In order to address the above problem, the technical solution adopted in the utility model is:
The straight feeding device of this sintering deposit, include the first chute that is arranged on the first below, belt conveyor discharging termination, be arranged on the second belt conveyor of described the first chute discharging opening below, described the second belt conveyor below is provided with the storage bin of receiving mineral aggregate, described storage bin discharging opening below is provided with the 3rd belt conveyor of mineral aggregate being delivered to the second chute, and the discharging opening below of described the second chute is provided with the 4th belt conveyor of mineral aggregate being delivered to blast furnace; Between described the first chute and described the second chute, be provided with and directly pull out chute, the described chute feed end that directly pulls out is connected with described the first chute, and the described chute discharge end that directly pulls out is above described the second chute; On described the first chute top, be provided with mineral aggregate is pulled out to the turnover panel that directly pulls out chute or described the first chute discharging opening to described.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, adopt after the utility model, one burns No. 1 machine sintering deposit directly pulls out material < 10mm grade through surge bunker minimizing 17.35% on 5, No. 6 blast furnaces, and wherein < 5mm grade reduces 6.88%; Two burn sintering deposit directly pulls out material < 10mm grade compared with surge bunker minimizing 13.19% on No. 2 blast furnaces, and wherein < 5mm grade reduces 4.36%; The direct benefit producing has:
1) save two and burn small sintering ore treating cost:
10500t/ (day) * 30(days) * 12(month) rate of return mine falls in * 4.36%() * 100 yuan/t(treating cost)=1648.08 (ten thousand yuan)/year
2) save one and burn No. 1 machine small sintering ore treating cost:
10500t/ (day) * 30(days) * 12(month) rate of return mine falls in * 6.88%() * 100 yuan/t(treating cost)=2600.64 (ten thousand yuan)/year
3) save the second belt conveyor (long 420.5m) and carry the electricity charge that consume:
90(KW) * 24 (hour) * 30 (my god) * 12 (moon) * 0.6 (unit/degree)=46.656(ten thousand yuan)/year
Save the 3rd belt conveyor (long 450.60m) and carry the electricity charge that consume:
200(KW) * 24 (hour) * 30 (my god) * 12 (moon) * 0.6 (unit/degree)=103.68(ten thousand yuan)/year
Total direct benefit (No. 1 machine of a burning, two burns till product sintering deposit):
Ten thousand yuan of 1648.08()+2600.64(is ten thousand yuan) ten thousand yuan of+46.656() ten thousand yuan of+103.68() ten thousand yuan of=4399.06()/year
2, No. 1 machine of the utility model minimizing one burning, two burns till product sintering deposit 10-5 millimeter particle level and is respectively 10.47%, 8.83%; Blast furnace permeability improves.
If 3 occur can finding in time and rectifying and improving into factory's sinter quality problem, for ironmaking, SINTERING PRODUCTION provides more in time, quality information accurately.
