A kind of pig machine dedusting mobile cover car
Technical field
The utility model relates to the environmental protection equipment of cast iron equipment, belongs to industrial ventilation dedusting field.This dedusting mobile cover car can help improving working environment, easy cleaning and replacing molten iron trough.
Background technology
Pig machine is the equipment that molten iron is continuously cast into iron block.Pig machine can produce a large amount of graphite dusts when turning over the jar cast, the workspace dust content is up to 130mg/m
3, also be attended by molten iron slag splash phenomena sometimes.In order to improve the safety and health that working environment guarantees producers, usually a dust arrester need be set above this zone.Dust arrester commonly used at present has two kinds: a kind of is under the situation that does not hinder production operation, and a fixing dust excluding hood and ventilation shaft are set above molten iron trough.One end of ventilation shaft connects dust excluding hood, and the other end is connected to the suction type cleaner.Because dust excluding hood is fixed, so when molten iron trough is cleared up and changed, need carry out dismounting to dust excluding hood, very trouble wastes time and energy.Another kind of mode is above molten iron trough, to set up track, arranges a movably dust excluding hood above, moves through hoist engine traction dust excluding hood.Because dust excluding hood can move, so cleaning and maintenance are changed molten iron trough than fixing dust excluding hood conveniently, still overhead owing to this dust excluding hood is distant apart from the dirt source point, the influence of the air-flow that is interfered easily, and seal is bad, and dust removing effects is not ideal.The problem of splashing of molten iron slag when this dust excluding hood can not solve pouring molten iron, in addition owing to the draw-gear that has adopted hoist engine, this kind mode complex structure, assembly pulley and steel wire rope floor space are bigger, cause the crowded and narrow of working region.The utility model can realize that dust excluding hood need not be overhead but steadily mobile by drive unit on the pig machine job platform, has good seal to improve efficiency of dust collection, can prevent that the molten iron slag from splashing, and avoided potential safety hazard simultaneously.
Summary of the invention
To the above-mentioned shortcoming that exists in the prior art, it is the mobile cover car of power with the drive unit that the purpose of the utility model provides a kind of, and as the cleaner of pig machine, this cleaner has good sealing property, and stable, flexible, reliable, efficiency of dust collection is high.Can improve working environment greatly, be convenient to the cleaning and the replacing of pig machine molten iron trough, improve the operating efficiency of pig machine.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:

The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
Like Fig. 1, shown in Figure 2, the pig machine dedusting mobile cover car of the utility model comprises dust excluding hood (2), pipeline docking facilities (3), drive unit (4), limit control (5), anti-protective device and the track clearing apparatus of overstepping the limit.
As shown in Figure 1, dust excluding hood (2) adopts π type longitudinal beam structure, and this structure can make longeron be higher than molten iron trough, makes dust excluding hood (2) can stride across molten iron trough, is set up on the track on the workbench.This kind structure make dust excluding hood (2) well airtight the dirt source point, reduced the influence of disturbing flow in the factory building, can stop well that also the molten iron slag splashes simultaneously; Dust excluding hood (2) adopts dome formula portal-framed structure, removes a side of hot-metal bottle cast and opens wide, and its excess-three face all has side plate airtight.When pouring molten iron, the hot-metal bottle of tumbling (1) has served as dust excluding hood (2) and has opened wide the side plate of a side.This kind structure can make petticoat pipe (2) press close to the flue dust point to greatest extent, has seal preferably; The distortion of exotic material with the caused dust excluding hood of heat radiation (2) of minimizing molten iron laid in the inboard of dust excluding hood (2); All offer observation window (2-1) on each side plate of dust excluding hood (2), be convenient to the workman and observe the situation that the interior hot-metal bottle of cover is toppled over molten iron; One side of dust excluding hood (2) is provided with cat ladder (2-3), is convenient to the pipeline docking facilities (3) on cover top is overhauled; The circular arc cover top of dust excluding hood (2) adopts bolt to be connected (2-4) with the frame structure of dust excluding hood (2), and this kind structure makes things convenient for the installation and removal of dust excluding hood (2);
As shown in Figure 4, the reducing motor (4-1) of drive unit (4) connects the driving shaft of driving wheel, and housing is connected on the longeron fixed support (4-2) through bearing pin (4-3).If two overlap drive units (4) in the right side of dust excluding hood (2), symmetric arrangement, this device can make dust excluding hood (2) move back and forth along track;
Limit switch as shown in Figure 5 (5-1) is installed on the track platform fixed support (5-2).Collision block (5-3) is fixed on the longeron, moves with dust excluding hood (2).Limit control (5) can make accurately location of dust excluding hood (2); The longeron two ends are provided with rubber bumper (6-1), and car bumper (6-2) is arranged on the two ends of track, prevent that dust excluding hood (2) from plunging off the tracks to cause accident; Be provided with the track clearing apparatus before and after the wheel of dust excluding hood (2), can clean the molten iron slag 1217 on the track, prevent to tumble when dust excluding hood (2) from moving.
When pig machine is prepared cast iron, start reducing motor (4-1) drive dust excluding hood (2) to hot-metal bottle (1) near.When reaching the dedusting station, the collision block (5-3) that is fixed on the longeron hits limit switch (5-1), reducing motor (4-1) braking, and dust excluding hood (2) halts.Pipeline docking facilities this moment (3) begins action.Like Fig. 2, shown in Figure 3, an end of pipeline docking facilities (3) is connected with dust excluding hood (2), and the other end is connected to the movably flange (3-4) of band air channel compensator (3-3).Electric pushrod (3-1) promotes flange (3-4), realizes rapid abutting joint with ventilation shaft (7).Flange (3-4) end is provided with sealing gasket (3-5) and guarantees sealing joint.The other end of ventilation shaft (7) is connected to depression dust-removing equipment; Electric pushrod (3-1) is fixed on the fixed support of docking facilities (3) both sides; There is guide rail (3-2) to control steadily moving of pipeline docking facilities around the compensator in the air channel (3-3); After butt joint was accomplished, hot-metal bottle (1) began cast.
When the pig machine molten iron trough need be cleared up or change, the electric pushrod (3-1) of pipeline docking facilities (3) was regained flange (3-4), threw off with ventilation shaft (7) to be connected.Start reducing motor (4-1) and drive dust excluding hood (2) to moving away from hot-metal bottle (1) direction.When reaching the maintenance station, the collision block (5-3) that is fixed on the longeron hits limit switch (5-1), reducing motor (4-1) braking, and dust excluding hood (2) halts.Just can just clear up this moment and operations such as molten iron trough are changed in handling.
After cleaning is changed operation and is finished, only need start reducing motor (4-1) once more and make dust excluding hood (2) move to the dedusting station and accomplish the pipeline butt joint, dedusting mobile cover car comes into operation again.
This equipment not only can well be realized smoke catching, and very helps cleaning and change molten iron trough.Enough fast switch from the dedusting station to check man's potential energy, reduced labour intensity, reduced the time of upkeep operation, can also effectively avoid potential safety hazard, thereby improved the operating efficiency of pig machine, increase economic benefit.
