Abstract

The utility model discloses a synchronizer of a double-directional moving exhaust pipe for an electric stove, which comprises an exhaust pipe, a servo speed-reducing machine, a rotating shaft, wheels, a guide rail, an electric screw rod, a telescopic bracket, and a compensation sliding block. The exhaust pipe comprises a telescopic-section exhaust pipe and a rotating-section exhaust pipe; the telescopic-section exhaust pipe is connected with the rotating-section exhaust pipe through the telescopic bracket; the electric screw rod pushes the telescopic-section exhaust pipe to move along the telescopic bracket; the servo speed-reducing machine drives the wheels of the driving car frame to move along the guide rail in straight line to drive the rotating-section exhaust pipe to swing through using the rotating shaft as the center; and the compensation sliding block is arranged between the rotating-section exhaust pipe and the car frame. In the utility model, the synchronous movement of the exhaust pipe and the electric-stove cover quadripuntal is along the guide rail; the step-aside movement of the exhaust pipe and the electric-stove cover quadripuntal is along the telescopic bracket; more smoke of the electric-stove can be exhausted without affecting the opening of the stove cover, the absorption of cold air is reduced, thereby increasing the smoke capture rate.

Description

Synchronizer for bidirectional-movement smoke exhaust pipe of electric furnace

Technical field

The utility model relates to a kind of smoke evacuation sychronisation, refers in particular to synchronizer for bidirectional-movement smoke exhaust pipe of electric furnace.

Background technology

Steel-smelting electric furnace institute discharged flue gas 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 gradually at present and popularize to the utilization of this high-temperature residual heat.At present, the smoke exhaust pipe of furnace lid four hole interfaces has only moving of a direction, and movable smoke exhaust pipe is fixed on the mobile framework, and oil cylinder promotes mobile framework, makes it to move along guide rail, realizes getting out of the way the motion in furnace lid four holes.And the direction activity smoke exhaust pipe that fascinates in furnace lid four holes can't be followed mobile, make movable smoke exhaust pipe be directly exposed to and sneak into a large amount of cold wind in the air, this just influences the smoke discharging effect of smoke exhaust pipe to electric furnace flue gas, electric furnace flue gas spills into the workshop in a large number, has influenced 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 efficient high-temperature residual heat that uses in the 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 moving of 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 purpose of this utility model is to provide a kind of can get out of the way the synchronizer for bidirectional-movement smoke exhaust pipe of electric furnace that moves on the direction of fascinating in the direction that moves in furnace lid four holes and four holes.

For achieving the above object, the utility model adopts following technical scheme: a kind of synchronizer for bidirectional-movement smoke exhaust pipe of electric furnace, it comprises smoke exhaust pipe, servo deceleration machine, gyroaxis, wheel, guide rail, and it further comprises electronic screw mandrel, telescope support, compensation slide block; Described smoke exhaust pipe is made up of telescopic section smoke exhaust pipe and meander sections smoke exhaust pipe, telescopic section smoke exhaust pipe and meander sections smoke exhaust pipe are connected by telescope support, electronic screw mandrel promotes the telescopic section smoke exhaust pipe and moves along telescope support, it is the center swing with the gyroaxis that wheel on the servo deceleration machine driving vehicle frame moves drive meander sections smoke exhaust pipe along the guide rail straight line, and described compensation slide block is arranged between meander sections smoke exhaust pipe and the vehicle frame.

Compared with prior art, the utlity model has following beneficial effect: the same moved further in smoke exhaust pipe realization and furnace lid four holes is along guide rail, smoke exhaust pipe is realized moving along telescope support with getting out of the way of furnace lid four holes, it can not influence under the situation that bell opens, more drain electric furnace flue gas, reduce the suction of cold air, thereby improved the flue gas trapping rate.

The specific embodiment

Below in conjunction with specific embodiment the utility model is further described.

Please refer to Figure 1 and Figure 2, a kind of synchronizer for bidirectional-movement smoke exhaust pipe of electric furnace, it comprises electronic screw mandrel 1, smoke exhaust pipe, telescope support 3, servo deceleration machine 4, gyroaxis 5, compensation slide block 6, wheel 7, guide rail 8.

Described smoke exhaust pipe is made up of telescopic section smoke exhaust pipe 2 and meander sections smoke exhaust pipe 9, telescopic section smoke exhaust pipe 2 and meander sections smoke exhaust pipe 9 are connected by telescope support 3, electronic screw mandrel 1 can drive telescopic section smoke exhaust pipe 2 and move along telescope support 3 and get out of the way electric furnace four holes, the wheel 7 that servo deceleration machine 4 drives on the vehicle frame moves along guide rail 8 straight lines, thereby driving meander sections smoke exhaust pipe 9 is the center swing with gyroaxis 5, and the realization smoke exhaust pipe is followed the swing in electric furnace four holes; The same moved further that is smoke exhaust pipe realization and furnace lid four holes is along guide rail, and smoke exhaust pipe is realized moving along telescope support with getting out of the way of furnace lid four holes.Described compensation slide block is arranged between meander sections smoke exhaust pipe and the vehicle frame.

Because the centre of gyration of meander sections smoke exhaust pipe connects so the meander sections smoke exhaust pipe need compensate slide block with being connected of vehicle frame to vicissitudinous distance between the tie point of meander sections smoke exhaust pipe and vehicle frame, the distance that compensation changes; Between compensation slide block and the meander sections smoke exhaust pipe is that rotary pair is connected, and compensating between slide block and the vehicle frame is that sliding pair is connected, and is the parts that connected two kinds of motions so compensate slide block, has satisfied the demand of this mechanism.

Following the motion of fascinating synchronously in bell four holes is realized by 2 servo deceleration machines, 2 servo deceleration machines drive on the vehicle frame front and back totally 4 wheel bands smoke exhaust pipe and realize and the fascinating synchronously of furnace lid four holes, the synchronizing signal of control servomotor by furnace ' s control system give with, thereby guaranteed the synchronous of smoke exhaust pipe and furnace lid four holes.

The motion of getting out of the way furnace lid four holes is that 1 electronic screw mandrel promotes the realization of telescopic section smoke exhaust pipe, and the telescopic section smoke exhaust pipe moves along telescope support, and electronic screw mandrel is driven by electrical apparatus control system.

Smoke exhaust pipe can be the water cooling tube that constitutes with cooling solid matter pipe, also can be the insulation smoke exhaust pipe that constitutes with refractory material.

The smoke exhaust pipe of the present utility model direction electricity consumption movable wire bar mobile getting out of the way furnace lid four holes realized moving, the direction of fascinating in furnace lid four holes smoke exhaust pipe with driven by servomotor vehicle frame band and is followed the swing of electric furnace four holes, can not influence under the situation that bell opens, more drain electric furnace flue gas, reduce the suction of cold air, thereby improved the flue gas trapping rate.
