Abstract
The invention relates to an electric furnace bidirectional movement flue synchronizing device. The synchronizing device comprises a flue, a servo reducer, an oil cylinder, a movable stand and a movable lead rail, wherein the flue is composed of a movable section flue and a fixed flue; the movable stand comprises a keeping-away movable stand and a following movable stand; the movable lead rail comprises a keeping-away movable lead rail and a following movable lead rail; the oil cylinder is connected with the movable section flue arranged on the keeping-away movable lead rail, and the servo reducer is connected with the following movable stand arranged on the following movable lead rail. The flue of the invention uses the oil cylinder to realize movement in the direction keeping away the movement of four holes on the furnace cover of the electric furnace, the servo motor is used to drive the flue to move with the four holes of the electric furnace in the tilting direction of four holes on the furnace cover of the electric furnace, thus the aim of realizing the synchronous movement of the flue and the electric furnace can be achieved and more electric furnace flue gas can be discharged without affecting the open of the furnace cover.
Description
Technical field
The present invention relates to a kind of smoke evacuation sychronisation, refer in particular to electric furnace bidirectional movement flue synchronizing device.
Background technology
The flue gas that steel-smelting electric furnace discharges contains a large amount of high-temperature residual heats, and waste heat flue-gas temperature big ups and downs and contain a large amount of dust are for the needs of energy-saving and emission-reduction, ripe and popularize gradually at present to the utilization of this high-temperature residual heat.At present, the smoke exhaust pipe of furnace lid four hole interfaces only has the movement of a direction, and the movable rows smoke pipe is fixed on the movable frame, and the oil cylinder pushing movable frame makes it to move along guide rail, realizes getting out of the way the motion in furnace lid four holes.And the direction movable rows smoke pipe that fascinates in furnace lid four holes can't be followed movement, so that being directly exposed to, the movable rows smoke pipe sneaks into a large amount of cold wind in the air, this just affects smoke exhaust pipe to the smoke discharging effect of electric furnace flue gas, electric furnace flue gas spills into the workshop in a large number, has affected the healthy of environment and workman, in addition, when connecing waste-heat recovery device behind the smoke exhaust pipe, because sneaking in a large number of cold wind caused the waste heat recovery quantity not sufficient, effectively do not reclaim heat.
Therefore for the high-temperature residual heat in the effective use steel-making flue gas, be necessary to study and a kind ofly can not only when opening bell, get out of the way four holes and move, can also when steel-making, follow the movement in furnace lid four holes, can make smoke evacuations less cold wind and the more raising exhaust gas temperature of sneaking in four holes in order to more recovery waste heats, and improve the device of electric stove dust effect.
Summary of the invention
The object of the present invention is to provide and a kind ofly can not only when opening bell, get out of the way four holes and move, can also when steel-making, follow the movement in furnace lid four holes, can more drain electric furnace flue gas, reduce the suction of cold air, thereby improved the flue gas trapping rate, obtained again the electric furnace bidirectional movement flue synchronizing device that higher cigarette temperature increases steam production.
For achieving the above object, the present invention adopts following technical scheme: a kind of electric furnace bidirectional movement flue synchronizing device, it comprises smoke exhaust pipe, servo deceleration machine, oil cylinder, movable stand and moving guide rail, described smoke exhaust pipe reaches fixedly by the mobile section smoke exhaust pipe, and smoke exhaust pipe forms, described movable stand comprises to get out of the way movable stand and follows movable stand, described moving guide rail comprises to get out of the way moving guide rail and follows moving guide rail, oil cylinder be arranged on the mobile section smoke exhaust pipe that gets out of the way on the moving guide rail and be connected, the servo deceleration machine be arranged on the movable stand of following of following on the moving guide rail and be connected.
Compared with prior art, the present invention has following beneficial effect: can not only get out of the way four holes when opening bell and move, can also follow the movement in furnace lid four holes when steel-making, can more drain electric furnace flue gas, reduce the suction of cold air, thereby improved the flue gas trapping rate.
Description of drawings
Fig. 1 is electric furnace bidirectional movement flue synchronizing device structural representation of the present invention.
Fig. 2 is electric furnace bidirectional movement flue synchronizing device motion state schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with specific embodiment.
Please refer to Figure 1 and Figure 2, a kind of electric furnace bidirectional movement flue synchronizing device, it comprises smoke exhaust pipe, oil cylinder 2, servo deceleration machine 3, movable stand and moving guide rail, described smoke exhaust pipe by be arranged on the vehicle frame mobile section smoke exhaust pipe 1 and fixedly smoke exhaust pipe 4 form, described movable stand comprises to get out of the way movable stand 6 and follows movable stand 8, described moving guide rail comprises to get out of the way moving guide rail 7 and follows moving guide rail 9, oil cylinder 2 be arranged on the mobile section smoke exhaust pipe 1 that gets out of the way on the moving guide rail 7 and be connected, servo deceleration machine 3 be assembled on the vehicle frame and be arranged on the movable stand 8 of following of following on the moving guide rail 9 and be connected.Get out of the way moving guide rail 7 and follow that angle is 90 ° between the moving guide rail 9.
Smoke exhaust pipe is the water cooling tube of cooling close arranging pipe formation or the insulation smoke exhaust pipe that consists of with refractory material.
Hydraulic oil cylinder driving mobile section smoke exhaust pipe 1 moves and gets out of the way electric furnace four holes along getting out of the way moving guide rail pair 7,3 drivings of servo deceleration machine are followed movable stand 8 and are done traveling priority along following moving guide rail 9, drive is got out of the way movable stand 6 and mobile section smoke exhaust pipe 1 and is followed electric furnace four holes and move, and realizes that smoke exhaust pipe follows the action of electric furnace four holes.
Follow the synchronization-moving motion in bell four holes by about 2 servomotors realize, 2 servomotors are by the synchronizing moving of 2 wheels on 2 servo deceleration machines driving vehicle frames with the realization of mobile section smoke exhaust pipe and furnace lid four holes, the synchronizing signal of control servomotor by furnace ' s control system give with, thereby guaranteed the synchronous effect in smoke exhaust pipe and furnace lid four holes.
The smoke exhaust pipe of the present invention direction mobile getting out of the way furnace lid four holes realizes mobile with oil cylinder, the direction of fascinating in furnace lid four holes is followed electric furnace four holes with the driven by servomotor vehicle frame with smoke exhaust pipe and moved, and reaches and the synchronization-moving purpose in electric furnace four holes.
