Description
Technical field
The utility model relates to the hot-blast stove field, is a kind of chain-arranged type energy-saving hot blast furnace.
Background technology
At present, China composite fertilizer manufacturing enterprise has reached family more than 16000, and total output is above 300,000,000 tons.But drying plant falls behind, and composite fertilizer's production line of about 95% still uses the baking of old-fashioned handwarmer heat, and will use high-quality anthracite to act as a fuel, and utilization rate is low, and coal consumption is big, and cost is high, and labour intensity is big, wastes energy, and has increased production cost; And heat supply is unstable, also has influence on the quality of production of composite fertilizer.
Summary of the invention
The purpose of the utility model is that a kind of chain-arranged type energy-saving hot blast furnace will be provided, and heat supply is stable, can improve the quality of product.
The utility model is achieved in that by coaling machine, coal bunker, coal flashboard, grate and furnace grate support to be formed; It is characterized in that on the front end of furnace grate support coal bunker and coal flashboard being housed, traveling-grate stoker is looped around on the furnace grate support, and a side of furnace grate support is equipped with several air registers, under the rear end of furnace grate support mucking machine is arranged; Furnace grate support places in the grate, and furnace lining is arranged in the grate, and there are mud chamber and air outlet in the rear end in the grate; Little arch before front end in the grate has; Link to each other with the front wall of furnace lining and grate, the middle-end in the grate has the little arch in back, and the rear end of furnace grate support is fixed on the wall of the little arch in back; Coaling machine places the outer front end of grate.
Grate is to process the outer that column, stull, pull bar are fixed on furnace lining with angle steel.
Furnace lining is domes, and both sides external is built exterior wall by laying bricks or stones with common brick, cement brick, and inner both sides are built interior wall and big arch by laying bricks or stones with refractory brick, and vault is cast with refractory material, and the application insulation material is used concrete casting again.
Before the vault of little arch cast with refractory material, the front of preceding little arch is cast into fire clay and blocks wall with flues.
The vault of the little arch in back is cast with refractory material, and the front and back of the little arch in back are all built by laying bricks or stones with refractory brick and become to block wall with flues.
Owing to adopted technique scheme, simple in structure, heat supply is stable, has improved the quality of product, can use any coal, has reduced production cost again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the drawings: 1, coaling machine; 2, coal bunker; 3, coal flashboard; 4, traveling-grate stoker; 5, grate; 6, furnace lining; 7, air register; 8, mucking machine; 9, mud chamber; 10, air outlet; 11, furnace grate support; 12, preceding little arch; 13, the little arch in back.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation further.
In Fig. 1, coal bunker 2 and coal flashboard 3 are housed on the front end of furnace grate support 11, traveling-grate stoker 4 is looped around on the furnace grate support 11, and a side of furnace grate support 11 is equipped with several air registers 7, and mucking machine 8 is arranged under the rear end of furnace grate support 11; Furnace grate support 11 places in the grate 5; Furnace lining 6 is arranged in the grate 5; There are mud chamber 9 and air outlet 10 in the rear end in the grate 5, and little arch 12 before the front end in the grate 5 has links to each other with the front wall of furnace lining 6 with grate 5; Middle-end in the grate 5 has the little arch 13 in back, and the rear end of furnace grate support 11 is fixed on the wall of the little arch 13 in back; Coaling machine 1 places the front end outside the grate 5.
Grate 5 is to process the outer that column, stull, pull bar are fixed on furnace lining 6 with angle steel.
Furnace lining 6 is domes, and both sides external is built exterior wall by laying bricks or stones with common brick, cement brick, and inner both sides are built interior wall and big arch by laying bricks or stones with refractory brick, and vault is cast with refractory material, and the application insulation material is used concrete casting again.
Before the vault of little arch 12 cast with refractory material, the front of preceding little arch 12 is cast into fire clay and blocks wall with flues.
The vault of the little arch 13 in back is cast with refractory material, and the front and back of the little arch 13 in back are all built by laying bricks or stones with refractory brick and become to block wall with flues.
Bituminous coal joins in the coal bunker 2 through coaling machine 1; Regulate 3 controls of coal flashboard and enter into the coal seam thickness on the traveling-grate stoker 4, after traveling-grate stoker 4 runs to lighting door, add the wood ignition coal seam operation of igniting; Fixed combustion produces flue gas subsequently; By the herringbone structure that preceding little arch 12 and the little arch 13 in back are formed, make high-temperature flue gas form vortex at the zone line of preceding little arch 12 and the little arch 13 in back, help the abundant burning in coal seam; Cinder after the burning is discharged through mucking machine 8, and the dust that high-temperature flue gas is carried secretly gets into mud chamber's 9 sedimentations, and the flue gas that baker produced is discharged by air outlet 10.
