Description
Technical Field
The invention relates to the technical field of reclaimed copper production process equipment, in particular to a fixed anode furnace with an adjustable furnace top.
Background
The furnace top of the existing fixed anode furnace adopts a fixed arch furnace top (referred to as a vault for short) structure. When the vault is built, arch foot bricks are symmetrically built on the tops of furnace walls on two sides of a fixed anode furnace to serve as two ends of the furnace top, arch foot bricks are built into arch brick rings with certain radian by a plurality of wedge-shaped refractory bricks (called as arch bricks), and the furnace top is formed by a plurality of arch brick rings. The vault is a single layer and consists of arch bricks with the same length and width, the side surfaces of the adjacent arch bricks are mutually locked, the load (dead weight and upper load) borne by the vault is decomposed into a downward vertical component force and a horizontal component force, the vertical component force is transmitted to the furnace wall through the arch foot bricks, and the horizontal component force is transmitted to the furnace wall upright posts through the arch foot bricks and the arch foot positioning bricks. Because the furnace wall and the furnace wall upright post can reliably bear large force, the vault can reliably bear dead weight and considerable upper load, and the structure is kept stable and does not sink.
However, the furnace top structure of the fixed anode furnace is a fixed structure and cannot be adjusted, so that the following disadvantages are present:
firstly, the thermal compensation of the local furnace top can not be realized, and the faults of 'uplifting of the arch bricks' and 'extrusion breakage of the arch bricks' are generated.
Before a newly built or stopped fixed anode furnace is put into use, the furnace needs to be dried, the temperature of a hearth is raised from a cold state to 1200-1300 ℃ by burning fuel, and then the temperature is maintained in the temperature range for production. In the early stage of furnace baking and production, the vault is heated and the volume is obviously expanded, and the conventional method is to loosen the furnace wall upright post pull rods on the two sides of the furnace body to compensate the thermal expansion of the whole furnace vault arch. However, the temperature distribution in the hearth is not uniform, the temperature difference between different brick rings and different positions of the same brick ring is large, and the expansion amount of the arch bricks is large or small. When the furnace wall upright post pull rod is loosened, the whole thermal compensation can be only carried out on the whole vault, under the condition that the whole thermal compensation is in place, the expansion amount of local arch bricks positioned in a high-temperature area is large and is not fully thermally compensated, the gap between the arch bricks at the position after the furnace is baked can be too small, a small number of arch bricks can be extruded by adjacent arch bricks to be lifted upwards and even be extruded and broken, the interlocking area of the arch bricks after being lifted/extruded and broken and the adjacent arch bricks is greatly reduced, the capacity of bearing self weight and upper load of the brick ring structure at the position is greatly weakened, and the risk of vault collapse is generated. As production time goes on, the stability of the structure of the brick ring in place is further destroyed and the vault risks collapsing at any time.
Secondly, the cold compensation of the local furnace top can not be realized, and the fault of 'sinking of the arch bricks' is generated.
When the fixed anode furnace is stopped, the temperature of the hearth is reduced to normal temperature, and the volume of the arch top is obviously shrunk along with the temperature. The conventional method is to tighten the furnace wall column pull rods at the two sides of the furnace body to compensate the shrinkage. When the furnace wall upright post pull rod is tightened, the whole vault can only be subjected to integral cold compensation.
When the furnace is baked, in order to prevent the arch bricks in the high-temperature area from being lifted and extruded, the whole vault is often subjected to excessive thermal compensation, i.e. the pull rod of the vertical column of the furnace wall is too loose, so that the expansion of the arch bricks in the high-temperature area is fully thermally compensated. Correspondingly, the expansion amount of the arch bricks in the low-temperature area is small, and the gaps among the arch bricks are too large.
When the furnace is shut down, under the condition that the whole cold compensation of the vault is in place, the shrinkage of the local arch bricks in the low-temperature area cannot be fully compensated, the gaps among the arch bricks at the position are further enlarged, a few arch bricks cannot be interlocked with the adjacent arch bricks, and the brick body obviously sinks. The interlocking area of the sunk arch brick and the adjacent arch brick is greatly reduced, the capacity of the brick ring structure for bearing self weight and upper load is greatly weakened, and the risk of vault collapse is generated. As the production time goes on, the times of blowing in and blowing out are increased, the stability of the structure of the brick ring is further damaged, and the vault risks to collapse at any time.
Thirdly, the arch crown has weak capacity of bearing the load below, and the fault of 'lifting up the arch brick' is generated.
The dome is capable of reliably carrying substantial overhead loads, and is only dead-weight. The structural feature is that it is difficult to withstand the load from below the vault.
In the production of the fixed anode furnace, the inside of the hearth is in a positive pressure state for a long time, the arch crown bears the load from the lower part, and the arch bricks are gradually pushed to lift. Because the degree of lifting on the arch bricks is inconsistent, the interlocking capability between the arch bricks is greatly reduced, the stability of the brick ring structure is damaged, and the risk of vault collapse is generated. As production time goes on, the stability of the structure of the brick ring in place is further destroyed and the vault risks collapsing at any time.
In addition, a common error in the fixed anode furnace charging operation is that the charging machine impacts the lower part of the arch crown, and the huge impact force is brought to extrude the arch brick at the impact point to enable the arch brick to be lifted up rapidly. This condition belongs to the vicious 'arch brick uplift' fault, and all or most of the bricks uplifted arch bricks can be separated from the brick ring, so that the brick ring is disintegrated, and the vault is collapsed along with the brick ring.
And fourthly, the safety of the structure is poor, and the fault of 'arch brick sinking' is generated.
In the arch top brick ring, brick joints are reserved between the arch bricks. The common quality defect during the building of the furnace top is that local brick joints are too large, and the quality defect is hidden and cannot be thoroughly eliminated through acceptance inspection. In the baking process of the fixed anode furnace and the initial production stage, a few arch bricks with the quality defect obviously sink (completely separate from the brick ring in the extreme case), the stability of the brick ring structure is damaged, and the risk of vault collapse is generated. Along with the production time, the sinking degree of the arch brick is further increased, the stability of the structure of the brick ring is further damaged, the brick ring is even disintegrated, and the risk of collapse at any time exists in the arch crown.
And fifthly, the vault can only be repaired in a cold mode after the failure, and the overhaul cost is high.
After the arch crown of the fixed anode furnace has the faults of 'arch brick uplifting', 'arch brick extrusion breaking' or 'arch brick sinking', the fixed anode furnace can only be processed by adopting a cold repair mode: firstly, blowing out the furnace, and reducing the temperature of a hearth to normal temperature; and secondly, removing the brick ring where the fault point is located and the adjacent brick rings, and finally building the brick rings again. This type of inspection is performed in a cold state (normal temperature state) of the furnace, and is different from a "hot state (high temperature operating state)" during operation, and is therefore called "cold repair".
After cold repair, the fixed anode furnace needs to be baked, and then the fixed anode furnace can be put into use again. Therefore, the total construction period of the cold repair mode is long, and the production organization of an enterprise is adversely affected; meanwhile, high cost of refractory bricks and high cost of fuel for baking the furnace are generated; and the service life of the fixed anode furnace can be greatly shortened in the processes of blowing out for cooling before cold repair and blowing in for heating after cold repair.
In most cases, the faults of 'arch brick uplifting', 'arch brick breaking and' arch brick sinking 'of the arch crown of the fixed anode furnace initially occur in a local range of the furnace top, and an early fault point is even just one arch brick, but only cold repair' treatment can be adopted, so that the overhaul cost is high.
