Description
Technical field
The invention relates to the device of producing fused magnesite in a kind of refractories industry.
Background technology
Energy resource consumption in the fused magnesite production process all is an electric energy almost, and power consumption accounts for more than 60% of production cost, and therefore, electric energy is the important component part that constitutes the fused magnesite production cost.Along with the intensification of China's imbalance between power supply and demand is constantly paid close attention to electricity needs with country, reduce the power consumption in the electric-melting magnesium production process, be not only the needs of national economic development, also be that enterprise reduces production costs, improve the important channel of product yield and quality.
Traditional electric melting magnesium furnace can not rotate in the body of heater sintering process, can produce sintering dead angle between electrode like this, causes a part of raw material not melt fully, causes whole stove can not make full use of raw material, increases for the ton power consumption of enterprise; Simultaneously original messenger wire formula rise fall of electrodes can cause fused magnesite electric current in process of production unstable, the probability that phenomenons such as stove occur leaking outside, wear strengthens; Original stove is to utilize by hand to carry out material loading and cloth, has increased labour intensity like this, and artificial material loading is also inhomogeneous simultaneously, on sintering, has influenced product quality.
Summary of the invention
The invention provides a kind of finished product rate that improves single stove product to existing the problems referred to above in the prior art, economizes on resources and the energy, reduces the full-automatic converter of energy-efficient electric-melting magnesium of labour intensity.
The technical scheme that the invention is adopted is: the full-automatic converter of energy-efficient electric-melting magnesium: furnace bottom rotational delay machine drives the furnace bottom rotating disc through swing pinion and rotates, and the furnace bottom rotating disc is provided with the furnace bottom car, and the furnace bottom car is provided with converter; Feed bin communicates with cloth lift telescopic pipe through the tubular type oscillating feeder, the end of the cloth lift telescopic pipe six pawl distributors that evenly distribute, and it is flexible that hoist engine drives cloth lift telescopic pipe through the steel wire rope I, and then drive six pawl distributors and move up and down; Transformer is connected with weak point net system; Weak point net system is provided with current transformer; Weak point net system is connected with conductive cross arm through lead, the other end fixed electrode of conductive cross arm, and the rise fall of electrodes reductor moves up and down through the rack drives conductive cross arm; And then drive electrode and move up and down, steadily go up and down through steel wire rope II and pulley maintenance conductive cross arm; Water in the cooling water tank circulates at the inner chamber of conductive cross arm with weak point net system through pipeline; Control device is controlled furnace bottom rotational delay machine, tubular type oscillating feeder, transformer and rise fall of electrodes reductor respectively, and current transformer is connected with control device.
The beneficial effect of the invention is: 1. furnace bottom rotational delay machine drives the rotation of furnace bottom rotating disc through swing pinion; And then converter rotation is above that established in drive; Rotating speed changeed/8 hours at 1-2, along with the rotation of 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 is given electrifying electrodes through short net system and conductive cross arm, makes the electrode end short circuit dischange and produces high temperature, makes the raw material fusing; At this moment electric current increases; Current transformer is delivered to the control system with current information, and the control system adjusts the up-down of electrode according to the height of electric current, (past rising that electric current is high; Past decline that electric current is low) guarantee that Current Control at 16000A, has reduced reactive loss.3. owing to be provided with tubular type oscillating feeder and six pawl structure of distributor, raw material is evenly fallen in the converter, guarantee the abundant fusing of raw material.4. the water in the cooling water tank, has reduced the temperature of short net system and conductive cross arm, thereby has guaranteed the serviceability rate and the operational efficiency of equipment in the inner chamber circulation of conductive cross arm with weak point net system through pipeline.5. further keep conductive cross arm steadily to go up and down through steel wire rope and pulley; And then guarantee that electrode steadily rises, make 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 make full use of raw material, the manual operations of the heaviness of original old backwardness is broken away from come, and all realizes automations in the whole sintering process.Adopt the invention to make enterprise's comprehensive indicator of power consumption of fused magnesite unit product drop to 2000KWh/T, practiced thrift the resource and the energy by 2800kWh/T.
