Abstract
The invention relates to an alumina conveying system and method, including directly conveying alumina to the hopper of a bucket type hoister from chute and hoisting the alumina to top of alumina bin by the bucket type hoister. The invention conveys alumina by utilizing a bucket type hoister instead of a pneumatic hoisting device initially in alumina production, thus greatly reducing power consumption of hoisting alumina vertically; besides a travelling apron is spared, conveying link is reduced, and horizontal conveying power consumption is reduced; and dynamic conveying is changed into static conveying, thus greatly reducing abrasion in conveying process. Practice shows that power is reduced to 75kW from original 185kWx2 under the conditions that conveying capacity is 300t/h and material is hoisted to the top of alumina bin by utilizing a steel wire adhesive tape bucket type hoister instead of a pneumatic hoisting device.
Description
Technical field
The present invention relates to process for making alumina, specifically, relate to a kind of system and method for carrying aluminum oxide.
Background technology
The conveying of alumina product generally is to be delivered to rubber conveyer with air-driven chute in the alumina producing, and rubber conveyer is delivered to strength lifting device again, utilize then the airlift vertical conveying device again vertical transport to aluminum oxide warehouse.
Prior art adopts strength lifting device to transport the aluminum oxide finished product, adopts rubber conveyer to carry to be very much progress than traditional method, reduces investment, increase production capacity, and owing to adopt the medium of gas as conveying products, can not pollute by carries product, have its outstanding advantage.
The core apparatus of airlift vertical conveying device is an air lift mud pump, and air lift mud pump is equivalent to a low pressure fluid tank, is made up of feeding warehouse, airlift pipeline, separation bin and two cover air feeders etc.Feeding warehouse contains a cover air feeder, is used for the material inflation, makes the complete fluidization of material in the storehouse, forms an inflation bottom in feeding warehouse.Rising pump is another set of air feeder, and its top is the pump housing, and the bottom is a vaporizer, and the centre is separated with the porous breathable plate.Nozzle is equipped with in a wind outlet, aims at carrier pipe: the expansion storehouse is equipped with in the outlet of auxiliary material pipe top, and secondary air links to each other with vaporizer, sees through air-permeable layer, ash is blown afloat form paralysed attitude state, upwards carries by the airlift pipeline.
The advantage of airlift method is that simple in structure, in light weight, the motion parts of equipment only is air and material, and movement-less part, wearing and tearing are little, convenient operating maintenance is reliable, and charging simultaneously, discharging, carries continuously, and when working, it is a self-compensating system.But shortcoming also clearly mainly contains:
1, adopts rubber conveyer to carry and increased middle-chain and energy consumption;
2, the strength lifting device energy consumption is very big;
3, strength lifting device is carried high rigidity material, delivery system quick abrasion.
Summary of the invention
For overcoming above-mentioned defective, the purpose of this invention is to provide a kind of delivery system and method for aluminum oxide.
The delivery system of aluminum oxide of the present invention comprises chute I, chapelet and chute II, chute I is used for aluminum oxide is transported to the material-falling hopper of chapelet, and chapelet next-door neighbour aluminum oxide feed bin is provided with, and is used for aluminum oxide and rises to aluminum oxide feed bin Cang Ding; Chute II is arranged at aluminum oxide feed bin Cang Ding, is used for the aluminum oxide that rises to aluminum oxide feed bin Cang Ding is sent into the aluminum oxide feed bin.
The preferred steel wire rubber belt of wherein said chapelet chapelet.
Described chute I and chute II are air-driven chute.
The carrying method of aluminum oxide of the present invention is that aluminum oxide is delivered directly to the material-falling hopper of chapelet from chute, rises to the aluminum oxide warehouse top with chapelet.
For reducing wearing and tearing, described chapelet adopts steel wire rubber belt chapelet; Described chute is an air-driven chute.
The chapelet vertical transport was done on probation in the past in the aluminum oxide finished product is carried, and can not use because of discharging is bad.The chapelet that we are to use is the steel wire rubber belt, and result of use is very good.
The present invention is used for the aluminum oxide finished product with chapelet to carry first.All adopt strength lifting device to carry in the industry.The present invention is the manufacturability innovation.Compared with prior art, the present invention adopts the wire belt chapelet to carry out the vertical transport of alumina product in the production of aluminum oxide, reduces aluminum oxide vertical-lift watt consumption; And omitted rubber conveyer, and reduce conveying process, reduce the horizontal feed watt consumption; And dynamic transport become static the conveying, significantly reduce the wearing and tearing in the course of conveying.Facts have proved that the present invention replaces strength lifting device with the wire belt chapelet, and material is promoted to the aluminum oxide warehouse top, operational throughput 300t/h, power is reduced to 75kw by original 185kw * 2.
Description of drawings
Fig. 1 is the general flow chart of aluminum oxide e Foerderanlage in the prior art;
Fig. 2 is the general flow chart of aluminum oxide carrying method of the present invention.
Among the figure: 1, chapelet; 2, air-driven chute I; 2 ', air-driven chute II; 3, aluminum oxide feed bin; 4, penumatic elevator; 5, material gas separation bin; 6, airlift storehouse; 7, adhesive tape conveyor; 8, material-falling hopper.
Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
Try method of the present invention out at certain alumina producer.
Dispose a B800 * 46450mm wire belt chapelet (N-TGD type, Hefei Cement Research Design Institute), one of configuration motor Y280S-4/75kw, design operational throughput 500t/h, 45 meters of lift heights, next-door neighbour's aluminum oxide feed bin is provided with, 2 of configuration air-driven chutes.Constitute the delivery system of aluminum oxide.
As shown in Figure 2, the aluminum oxide delivery system comprises chute I 2, and chapelet 1 and chute II2 ', chute I 2 are used for aluminum oxide is transported to the material-falling hopper 8 of chapelet 1, chapelet 1 next-door neighbour's aluminum oxide feed bin 3 is provided with, and is used for aluminum oxide and rises to aluminum oxide feed bin 3 Cang Ding; Chute II 2 ' is arranged at aluminum oxide feed bin 3 Cang Ding, is used for the aluminum oxide that rises to aluminum oxide feed bin 3 Cang Ding is sent into aluminum oxide feed bin 3.
The aluminum oxide finished product is delivered directly to the hopper 8 of steel wire rubber belt chapelet 1 through air-driven chute I 2, this moment, hopper 8 was positioned at low level, vertical-lift material-falling hopper 8 under the effect of motor then, end until hopper 8 tracks, then aluminum oxide is poured into the air-driven chute II 2 ' that is arranged in aluminum oxide feed bin 3 tops, entered aluminum oxide feed bin 3 by air-driven chute II 2 '.Hopper 8 back and forth moves.
Since adopting method of the present invention to carry alumina product, operating performance is good, has not occurred wearing and tearing and other problems since the self-operating.
The strength lifting device of original aluminum oxide is seen Fig. 1, the aluminum oxide finished product is transported to rubber conveyer 7 by air-driven chute 2, further be transported to the airlift storehouse 6 of penumatic elevator 4 by rubber conveyer 7, rise to aluminum oxide feed bin 3 Cang Ding through penumatic elevator 4, realize that at the glassware separation bin 5 of penumatic elevator 4 material gas separates, isolated aluminum oxide enters aluminum oxide feed bin 3 by air-driven chute II 2 '.
Alumina producing is continuity production in 24 hours, compares with the strength lifting device of original aluminum oxide, adopts method and system of the present invention, but every year save power:
(185kw * 2-75kw) * 24 hour * 330 days=2336400kwh
And, owing to saved adhesive tape conveyor, also reduced facility investment.
