Summary of the invention
The invention, for existing the problems referred to above in prior art, provides a kind of finished product rate that improves single stove product, economizes on resources and the energy, reduces the full-automatic converter of energy-efficient electric smelting magnesium of labour intensity.
The technical scheme that the invention adopts is: the full-automatic converter of energy-efficient electric smelting magnesium: furnace bottom rotation reductor drives the furnace bottom rotating disc by swing pinion and rotates, and the furnace bottom rotating disc is provided with furnace-bottom vehicle, and furnace-bottom vehicle is provided with converter; Feed bin communicates with cloth lift telescopic pipe by the tubular type oscillating feeder, and the end of cloth lift telescopic pipe is uniformly distributed six pawl distributors, and it is flexible that hoist engine drives cloth lift telescopic pipe by the steel wire rope I, and then drives six pawl distributors and move up and down; Transformer is connected with short net system, short net system is provided with current transformer, short net system is connected with conductive cross arm by wire, the other end fixed electrode of conductive cross arm, the rise fall of electrodes reductor moves up and down by the rack drives conductive cross arm, and then be with moving electrode to move up and down, keep the steady lifting of conductive cross arm by steel wire rope II and pulley; Water in cooling water tank is the inner chamber circulation in conductive cross arm and short net system by pipeline; Control device is controlled respectively furnace bottom rotation reductor, tubular type oscillating feeder, transformer and rise fall of electrodes reductor, and current transformer is connected with control device.
The beneficial effect of the invention is: 1. furnace bottom rotation reductor drives the rotation of furnace bottom rotating disc by swing pinion, and then converter rotation is thereon established in drive, rotating speed turns at 1-2/and 8 hours, rotation along with raw material, can not produce the sintering dead angle between electrode, raw material is fully melted, reduce the ton power consumption of enterprise.2. transformer by short net system and conductive cross arm to electrifying electrodes, make the electrode end short circuit dischange and produce high temperature, make the raw material fusing, at this moment electric current increases, current transformer is delivered to control system by current information, and control system is adjusted the lifting of electrode according to the height of electric current, (the electric current height past rising, past decline that electric current is low) guarantee that Current Control, at 16000A, has reduced reactive loss.3. owing to being provided with tubular type oscillating feeder and six pawl structure of distributor, raw material is evenly fallen in converter, guarantee the abundant fusing of raw material.4. the inner chamber circulation in conductive cross arm and short net system by pipeline of the water in cooling water tank, reduced the temperature of short net system and conductive cross arm, thereby guaranteed serviceability rate and the operational efficiency of equipment.5. further keep the steady lifting of conductive cross arm by steel wire rope and pulley; And then guarantee that electrode steadily rises, make the current stabilization in the production process of fused magnesite.In a word, the invention can improve on the one hand the finished product rate of single stove product, also can take full advantage of raw material, also makes the manual operations of the heaviness of original old backwardness break away from simultaneously and comes, and all realizes automation in whole sintering process.Adopt the invention to make enterprise's comprehensive indicator of power consumption of fused magnesite unit product drop to 2000KWh/T by 2800kWh/T, saved resource and the energy.
The accompanying drawing explanation
Fig. 1 is the structural representation of the invention.
