Description

Device convenient to change yellow phosphorus electric stove eye electrode

Technical Field

The utility model belongs to the technical field of overhaul of yellow phosphorus electric furnaces, and particularly relates to a device convenient for replacing a yellow phosphorus electric furnace hole electrode

Background

Yellow phosphorus has wide application and is one of very important chemical raw materials. The total scale, yield and export of yellow phosphorus production in China are the first world, yellow phosphorus production enterprises in China mostly adopt an electric furnace method for preparing phosphorus, phosphate ore, white coal and silica are added into an electric furnace according to a certain proportion, wherein the silica is used as a fluxing agent, the white coal is used as a reducing agent and a conductor, electric energy is introduced to convert the electric energy into heat energy to melt the heat energy to generate chemical reduction reaction, and a large amount of yellow phosphorus gas is generated at the same time of generating yellow phosphorus. The furnace body inevitably presents damage with different degrees in the operation process of the electric furnace, so that the service life of the electric furnace is seriously influenced, and the normal operation of the electric furnace is hindered. Besides erosion thinning of refractory materials of the furnace bottom and the furnace wall, the electrode of the electric furnace is eroded and corroded by slag and ferrophosphorus water at about 1450 ℃ for a long time, the erosion of the hole diameter of the furnace is large, when the hole diameter of the furnace exceeds 150mm, the flow rate of slag passing through the furnace hole is greatly increased in the discharging process of the electric furnace, the slag is emptied in a short time, the furnace of the yellow phosphorus electric furnace is instantaneously and largely collapsed, the electrode of the furnace cover is triggered to be askew, and the electrode breakage accident is seriously generated; meanwhile, after the slag discharge amount is greatly increased, the capability of the slag quenching system for treating and cooling high-temperature slag is exceeded, so that slag is collected and floodwater is caused in the U-shaped slag flushing ditch, and the high-temperature slag has the safety risks of high-temperature scalding after overflowing the operating platform in front of the furnace and uncooled ferrophosphorus exploding in water to hurt people; meanwhile, excessive high-temperature slag does not cool the quenching slag in time, so that equipment accidents of damaging a dehydrator are easy to occur; in addition, a large amount of furnace gas instantaneously leaks along with high-temperature furnace slag, and the pollution of the furnace front gas caused by the incomplete treatment of a furnace hole gas fan can be caused; particularly, the difficulty of blocking the furnace is increased after the electrode furnace hole is enlarged, the safety risk is high, and the furnace hole is easy to overflow.

Aiming at a plurality of defects of yellow phosphorus electric furnace electrodes after serious furnace eyes are corroded, in order to ensure safe and stable operation of the electric furnace, yellow phosphorus production enterprises usually plan to stop production for half a year to replace and overhaul furnace eyes.

The electric furnace hole structure is mainly formed by building refractory materials such as furnace hole carbon bricks, clay bricks, high-alumina bricks and the like, and is plugged by self-made water stemming with electrode paste slag, clay and water which are uniformly mixed. Therefore, when the furnace hole electrode is replaced, the furnace hole electrode is rotated by adopting the general bulk methods such as pneumatic pick enlarging hammer, steel drill and the like. The operator is required to perform wheel battle, the whole electrode is crushed and hollowed from outside to inside (A of figure 1), and the maintenance mode has the defects that the time is long, and generally, 4-5 days are required for drilling one furnace hole; secondly, the labor intensity is high, the personnel demand is high, two shifts are required to be carried out without interruption, 6 people are required to be carried out in each shift, and the total number of the people is 12; thirdly, the consumable is more, because the total length of the furnace hole electrode is 1400mm, the special pneumatic pick drill (B in figure 1) with different lengths of 300mm, 500mm, 1000mm and 1500mm is needed to replace from outside to inside, because the stopping time of the electric furnace is shorter, the high-temperature carbon electrode furnace hole wears the tip of the pneumatic pick drill more quickly, and the breaking and replacing frequency is higher; fourthly, the positioning is difficult, the drilling technical requirement is high, the drilling deviation, slipping and the blocking of the pick drill bit are easy, the inner wall of the drill hole is rugged (C in figure 1), and the installation of a new furnace hole and the pouring of electrode paste are inconvenient; fifthly, the construction process has more potential safety hazards, and the risk of difficult prognosis caused by high-temperature scalding, smashing injury, sliding, heatstroke and cross operation can exist. Chinese patent CN207894254U discloses a device for replacing an electrode of an electric furnace, which is to fix an auxiliary electrode when replacing the electrode by a hoop, shorten the electrode cooling time during electrode maintenance by a cooling pipeline, and improve the electrode maintenance efficiency. However, at present, no device capable of accelerating the breaking of the old furnace eye electrode and improving the electrode replacement efficiency exists.
