The present invention relates to metal smelt technical field of dust removal equipment, a kind of intermediate frequency furnace dust trapping device, I.e. can vertically move again by transverse shifting, when following intermediate frequency furnace tapping, flue dust point moves and is tracked dedusting.
Background technology
The operating frequency of intermediate frequency furnace, between 50-10Hz, is widely used in the melting of non-ferrous metal and ferrous metal, with other Casting Equipment compares, medium-frequency induction furnace has that the thermal efficiency is high, smelting time is short, alloying element scaling loss is few, melting material is wide, The advantages such as environmental pollution is little, temperature and the composition that can accurately control molten metal.
The dust trapping device of the small intermediate frequency stove dust pelletizing system stokehold that this enterprise is used is arranged on the top of intermediate frequency furnace, Using cantilever to rotate round floating bearing, thus drive fume ducts, fume trap cover to rotate, a smoke collecting cover is responsible for The smoke catching of two intermediate frequency furnaces worked time different.The fume trap cover of this dust trapping device can not along with intermediate frequency furnace tap time The reach of flue dust point and the most mobile, it is impossible to enough trapping flue dust completely, dust removing effects is undesirable, and efficiency of dust collection is low, particularly casts During iron ball, dust removing effects does not reaches far away environmental requirement.
Summary of the invention
It is an object of the invention to provide a kind of intermediate frequency furnace dust trapping device, to solve the smoke catching of existing cleaner When cover can not follow intermediate frequency furnace tapping, the line trace that moves into of flue dust point traps flue dust, and dust removing effects is undesirable, efficiency of dust collection Problem low, that environmental requirement can not be met.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of intermediate frequency furnace dust trapping device, it includes umbrella roof suction flue dust fume trap cover, the top of smoke catching cover and flue dust The front end of pipeline is connected, and the rear end of fume ducts is connected with sack cleaner, blower fan, and the top of described smoke catching cover is solid Being scheduled in transversal stretching walking mechanism, transversal stretching walking mechanism is walked on the longeron of longitudinally walking framework, transversal stretching row Walking mechanism to be connected with the top of Electrohydraulic push rod, the bottom of Electrohydraulic push rod is fixed on the crossbeam of longitudinally walking framework;Lengthwise rows Walking the walking driver gear group being provided with on framework on road wheel track, walking driver gear group passes through chain wheel driving mechanism and planet Cycloidal planetary gear speed reducer is connected, and cycloidal planetary gear speed reducer is connected with motor.
Preferably, the described longitudinally walking top of framework, two bottom sides are respectively equipped with guiding wheels, guide wheels walking and exist On directive wheel track.
Preferably, described transversal stretching walking mechanism include being arranged on the flexible road wheel assembly on flexible walking framework, Flexible guide wheel assemblies, flexible road wheel assembly is walked on longitudinally walking framework.
Described Electrohydraulic push rod is a kind of mechanical, electrical, liquid integrated hydraulic driving mechanical, by actuator (oil cylinder), control Mechanism processed (hydraulic control valve group) and power source (Oil pump electrical machinery etc.) composition, in the present invention for push-and-pull transversal stretching vehicle with walking machine Structure is movable on longitudinally walking framework.
In use, operating personnel starts connection driven by motor cycloidal planetary gear speed reducer operating to the present invention, passes through chain Wheel drive mechanism drives the motion of walking driver gear group, makes longitudinal framework of walking realize vertically moving along road wheel track, to adjust Position between whole smoke catching cover and intermediate frequency furnace;When the metal completing to smelt in intermediate frequency furnace is come out of the stove, operating personnel controls electricity Liquid push rod stretches, and promotes transversal stretching walking mechanism to move, in making smoke catching cover follow along the longeron of longitudinally walking framework Frequently the line position that moves into of the flue dust point of stove adjusts, it is achieved the tracking suction of flue dust, improves efficiency of dust collection, meets metal smelt and make The environmental requirement in industry place.
The invention have the benefit that
(1) present invention drives the motion of walking driver gear group by cycloidal planetary gear speed reducer, makes framework realization of longitudinally walking Longitudinal movement, have adjusted the lengthwise position relation between smoke catching cover and intermediate frequency furnace;By the extension and contraction control of Electrohydraulic push rod Transversal stretching walking mechanism, so control smoke catching cover follow intermediate frequency furnace flue dust point move into line position adjust, it is achieved that The tracking suction of flue dust, is effectively improved efficiency of dust collection, meets environmental requirement;
(2) present invention is when intermediate frequency furnace normally works, and adjustment smoke catching cover is placed on the top of intermediate frequency furnace and carries out dedusting operation; When intermediate frequency furnace carries out feeding, overhauls, can move to smoke catching cover other positions, not affect charging, upkeep operation;This It is convenient that bright operation controls, practical;
(3) present invention uses cycloidal planetary gear speed reducer to have the advantages such as simple in construction, gear ratio is big, volume is little, power is little, Improve the reliability of this device, reduce the maintenance of equipment, the maintenance frequency, saved production, use cost;
(4) by the use of the present invention, it is achieved that the flue dust of intermediate frequency furnace follows the tracks of suction, the dedusting effect of intermediate frequency furnace is substantially increased Rate, on the premise of completing identical dust removing effects, the power of fan that this dust pelletizing system is selected can reduce half, consistent in parameter In the case of, sack cleaner filter area, the area of section of pipeline are the half of existing equipment, and manufacturing cost significantly reduces; In actual use, owing to power of fan reduces, power consumption also declines, it is achieved that energy-saving and emission-reduction, has appreciable Economic benefit and social benefit.
