Abstract
The utility model provides a rotary dust removing deflector of electric arc furnace, which is mainly characterized by the layering boards arranged inside a deflector body, the deflecting channels formed between the layering boards and between the layering boards and the deflector body, as well as a pipe-form turning gear and a gearing device. When in use, the deflector directed towards air current transfers caught smoke to a tumbler, then the smoke is discharged from the top of the tumbler into a fixed pipe then into a smoke purifying device; the tumbler has two functions, driving the deflector to rotate and making smoke moved with the air current; when the deflector is under dust removing condition, the roller bridge keeps normal running and the electrode of the electric arc furnace is able to be raised freely. The utility model has the advantages of reliable operating, compact structure, convenient installation and use and good dust removing effect with the dust catching rate reaching 85 percent to 95 percent.
Description
Technical field
The utility model belongs to air cleaning cleaner class, and specifically the smoke catching part of electric stove dust is the device of capture flue gas.
Background technology
During electric furnace steel making, flue dust fills the air, and workman's operating environment is very abominable.Since electric arc furnaces in 1905 invention, originally people are used in the development aspect of steel-smelting technology to energy, after nineteen sixty, just the electric stove dust aspect are paid attention to some extent.China is after 1970, and each factory has generally carried out the capture and the purification work of electric furnace dust.According to " foundry's dust removal by ventilation and technology " book introduction of nineteen eighty-three China Ministry of Machine-Building Industry publication, electric stove dust is covered with 24 kinds more than.
Flue gas (dusty gas) the temperature height that electric furnace produces, flow is big, fiercely emits from the hole of three electrodes, and everybody knows at electric furnace overhead with the cover mouth down, is a good method over against the dust excluding hood capture flue dust of ascending air.But because of people's thinking is confined to umbrella hood, the angle of dehiscing of this cover is no more than 60 °, must be from cover top smoke evacuation, and height overall is more than 4 meters, and the free space height under the overhead day vehicle passage of electric furnace is less than 2 meters, umbrella hood can't be installed.Therefore, the electric stove dust cover that adopts now mainly contains two kinds.
First kind is side-draught hood, and it is fixed on the electric furnace furnace roof, inhales from the periphery of three electrodes and catches flue gas, outwards inhales from horizontal direction and catches the flue gas that upwards emits, and suction is vertical with the buoyancy direction of flue gas, and the flue gas between three electrodes is difficult to capture.Therefore catch the cigarette weak effect.
Second kind is half-sealed cover, and it has a umbrella hood, but too high from electric furnace, is positioned on the roof, and overhead traveling crane running space below also has a kuppe, and kuppe is positioned on again on the top, semi-hermetic chamber that can remove, and when electric furnace was used the overhead traveling crane operation, the semi-hermetic chamber was left.Distance between umbrella hood and electric furnace is big, the flue gas diffusion, and it is a lot of that mist is increased.Therefore blower fan, deduster, pipeline etc. are all huger, and power consumption is also many.
Summary of the invention
The purpose of this utility model provides reliable operation at the deficiency that above existing dedusting technology exists, and compact conformation is easy to install, the electric arc furnaces Rotary dust collecting kuppe of good dedusting effect.
The electric arc furnaces Rotary dust collecting kuppe that the utility model design provides has a cover body, is characterized in the demixing plate of setting in the described cover body, and the flow-guiding channel that forms between demixing plate and demixing plate, demixing plate and the cover body constitutes.
Kuppe also has the whirligig and the transmission device of a pipe shape; Whirligig is fixed on the steel construction platform; Be provided with rotating cylinder in whirligig, rotating cylinder bottom transmission device links to each other; And rotating cylinder and top are inhaled cover and are joined, and flow-guiding channel is communicated with rotating cylinder.
The rotating cylinder cylindrical of above-mentioned described whirligig is provided with filler ring, platen, ball and annular chassis up and down; Rotating cylinder inserts in the platen, last ball be contained in the platen and filler ring above, following ball is contained on the annular chassis and between filler ring following, and by bolt and nut platen and annular chassis is linked together.
The electric furnace that the utility model design provides is compared with background technology with rotary electric arc stove Rotary dust collecting kuppe, and substantive distinguishing features that is had and tangible technique effect are:
Therefore 1, the total height of kuppe has only about 1 meter, can capture flue gas in the nearer sky of distance electric furnace, capture rate height not only, and also rational in infrastructure, easy for installation, can satisfy the requirement of electric furnace steel making.It is than the capture rate height of side-draught hood, than half-sealed cover is simple, convenient, rate of air sucked in required is lacked, less energy consumption, reduced investment.
2, whirligig is also very simple, and rotating cylinder is rotated by the steel ball supporting rolling between ring property shape chassis and platen, and is flexibly light and handy.
3, flue gas is along the fluid motion direction, and kuppe the flue gas that captures, is imported rotating cylinder in face of air-flow smoothly, and is discharged by the rotating cylinder top, enters fixed-piping, feeds flue gas purifying equipment.One of rotating cylinder body is dual-purpose, has both driven kuppe rotation, makes the flue gas following current again and moves.
Description of drawings
Fig. 1 is electric arc furnaces Rotary dust collecting kuppe structure and scheme of installation;
Fig. 2 is the partial enlarged drawing of whirligig.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment.
Shown in Figure 1, electric arc furnaces Rotary dust collecting kuppe.A cover body 1 is arranged, the demixing plate 101 that is provided with in the cover body, and the flow-guiding channel 102 that forms between demixing plate and demixing plate, demixing plate and the cover body constitutes.Kuppe also has the whirligig 2 and the transmission device 3 of a pipe shape; Whirligig is fixed on the steel construction platform 4; Be provided with rotating cylinder 201 in whirligig, rotating cylinder bottom transmission device links to each other; And rotating cylinder and top are inhaled cover and are joined, and flow-guiding channel is communicated with rotating cylinder.
Shown in Figure 2, whirligig.On rotating cylinder 201 cylindricals of whirligig 2, be provided with filler ring 202, platen 203, ball 204 and annular chassis 205 up and down; Rotating cylinder inserts in the platen, last ball be contained in the platen and filler ring above, following ball is contained on the annular chassis and between filler ring following, and by bolt (206) and nut 207 platen and annular chassis is linked together.
Above-mentioned transmission device is made up of motor, cycloid pin decelerator and sprocket wheel or gear.Transmission device drives the rotating cylinder rotation, and 90 ° of kuppe left-right rotation angles are perhaps rotated more wide-angle.When overhead traveling crane 5 to the furnace roof mouth of electric arc furnaces 6 during to furnace charge, kuppe left or turn right from the electric arc furnaces sky, after overhead traveling crane had fed in raw material, kuppe forwarded the sky of furnace roof again to.Therefore, just can dedusting when electric-arc furnace steelmaking, at this moment overhead traveling crane can normally move, and electrode can arbitrarily promote.
