Abstract
The utility model belongs to the dedusting field, and is widely applicable to an electric arc furnace. One side of the electric arc furnace is provided with a fixed cover; a fixed exhausting and sealing port is arranged at the upper side of the electric arc furnace; a movable cover matched with the fixed cover is seated on rails by a roller; the rails are respectively fixed on the ground and a steel beam; a movable cover exhaust port is arranged above the movable cover and is inserted with the fixed exhaust port; the roller is driven by a driving device; a sealing plate is arranged between the hood and a factory; and a gap between the hood and the factory room is sealed completely. The electric arc furnace hood has good sealing effect and does not influence the normal work of a crown block.
Description
Technical field
The utility model belongs to the dedusting field, is widely used in the electric arc furnaces dedusting.
Background technology
The dedusting petticoat pipe that existing electric arc furnaces dedusting is adopted roughly is divided into: semi-hermetic type mobile cover (ground), roof, workshop cover, portable top-draught hood.These three kinds hood-shaped in, though relatively in addition two kinds of dust removing effects are best for the semi-hermetic type mobile cover, can not the dirt source is airtight fully, mostly be because the field condition restriction, so that dust removing effects can not reach is best, as the weather of blowing, because the influence of extraneous air-flow must cause dust excessive; Roof, workshop cover needs very firm roof structure, so investment is bigger, and because of cover body to unlimited between the dirt source, dust removing effects is subjected to extraneous airflow influence more serious; Portable top-draught hood and roof cover are similar, are subjected to extraneous airflow influence serious, and generally limited because of distance between electric arc furnaces and roof, add and consider and the overhead traveling crane interference problem, so can't realize at a lot of factory buildings.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of gas hood of electric arc furnace, and its good sealing effect does not influence the overhead traveling crane operate as normal.
The technical scheme in the invention for solving the technical problem is: install and fix cover in electric arc furnaces one side, the side has fixedly to take out and seals on the electric arc furnaces, and the mobile cover that cooperates with fixed cover is sitting on the track by roller, and track is separately fixed on ground and the girder steel; There is the mobile cover suction opeing described mobile cover top, the mobile cover suction opeing and fixedly suction opeing plug together; Described roller is driven by drive unit, between petticoat pipe and factory building sealing plate is arranged, and the neutral that can not seal between petticoat pipe and factory building is sealed fully.
The utlity model has following advantage: 1, because of the cover body totally-enclosed, cover wall guiding, cover top dust suction are not subjected to extraneous airflow influence fully, have overcome the common drawback of above-mentioned three kinds of dedusting petticoat pipes; 2, adopt unique " factory " font design, track is complied with workshop appliance and arranged, and is one high and one low, avoided the interference with any equipment in workshop; 3, the cover body highest point is under the overhead traveling crane working depth, on the electric arc furnaces peak, during petticoat pipe work, do not influence overhead traveling crane and carry out other lifting job, when overhead traveling crane gives the scratch start stove reinforced, the mobile cover part can be removed, and the fixed cover part is not in the overhead traveling crane working range, so do not influence the overhead traveling crane operate as normal fully; 4, suction opeing adopts importing plug-in type activity to be connected design with extraneous air draft pipe on the mobile cover, and it is firm to connect, and need not purchase flexible interface equipment in addition, not only practicality but also economy.5, adaptability is strong, not restricted by overhead traveling crane, workshop existing equipment, and electric arc furnaces, electric stove dust are had general applicability.6, because of the petticoat pipe totally-enclosed, effectively reduce the pollution to external world of electric arc furnace smelting noise, improved worker's working environment greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the A-A cutaway view among the utility model Fig. 1.
The specific embodiment
As shown in drawings, install and fix cover 3 in electric arc furnaces 1 one sides, the side has fixedly to take out and seals 6 on the electric arc furnaces, and the mobile cover 2 that cooperates with fixed cover 3 is sitting on the track by roller, and track is separately fixed on ground and the girder steel; There is mobile cover suction opeing 5 described mobile cover 2 tops, and mobile cover suction opeing 5 plugs together with fixing suction opeing 6; Described roller is driven by drive unit 4, and sealing plate 7 is arranged between petticoat pipe and factory building, and the neutral that can not seal between petticoat pipe and factory building is sealed fully.
When overhead traveling crane gives electric arc furnaces 1 reinforced, mobile cover 2 under the effect of drive unit 4 left direction remove, as shown in Figure 2, mobile cover suction opeing 5 is thrown off with external stability suction opeing 5; When filling it up with 1 smelting of material electric arc furnaces, mobile cover 2 moves and fixed cover 3 closures to right-hand under the effect of drive unit 4, simultaneously mobile cover suction opeing 5 plugs together with fixing suction opeing 5, and at this moment overhead traveling crane can freely start above the mobile cover 2 that fixed cover 3 cooperates, and is independent of each other.
