Abstract
The utility model provides a silver stove partition wall passageway, changes including partition wall, door opening, gap bridge, the top of partition wall is equipped with the copper water jacket, the copper water jacket has refractory material to cut into, the door opening be located the central point of partition wall, the door opening is non-arch door opening, door opening height 970mm, wide 450mm, refractory material be the magnesia chrome brick, the gap bridge change into long 700mm, wide 150 mm's rectangle resistant firebrick. The partition wall channel of the silver furnace improves the service life of the silver furnace and reduces the maintenance cost.
Description
Technical Field
The utility model belongs to the technical field of pyrometallurgy, is mainly used for a double-chamber copper smelting furnace, and particularly relates to a partition wall channel of a silver furnace.
Background
The silver furnace is a double-chamber copper smelting furnace, and a molten pool is divided into a blowing zone and a precipitation zone by a partition wall. After the materials are added into the smelting zone, copper concentrate particles are scattered in the melt along with the stirring of the melt, and the processes of heating, decomposing, melting and the like of the materials are carried out through the rapid heat transfer between the huge surface area of the concentrate particles and the surrounding high-temperature melt; the copper matte formed by smelting enters a settling zone through a partition wall channel to carry out a static matte and slag separation process, and the two zones are mutually connected and independent. A partition wall is arranged between the smelting zone and the settling zone, and a channel is reserved below the middle part of the partition wall.
The existing intermediate partition wall masonry method comprises the following steps: the partition wall channel of the silver furnace is built from furnace walls on two sides to the center through electric melting and then combined with magnesia-chrome bricks, a channel with the height of 970mm and the width of 450mm is reserved at the center of the partition wall, an arched door opening is built above the channel and used for supporting a refractory material and a copper water jacket on the upper portion, during the production of the silver furnace, the arched door opening above the partition wall channel in the middle of the partition wall is easy to collapse due to the scouring of high-temperature melt and smoke, the furnace is stopped for building during re-building, the working efficiency is reduced, the service life is long, and the maintenance cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a partition wall channel of a silver furnace, which solves the problems that an existing arched door opening is easy to collapse due to the scouring of high-temperature melt and smoke, and is low in service life and high in maintenance cost.
In order to solve the technical problems, the technical scheme adopted by the utility model is as follows:
the utility model provides a silver stove partition wall passageway, includes partition wall 1, door opening 4, crosses the bridge and changes 3, the top of partition wall 1 is equipped with copper water jacket 5, copper water jacket 5 has refractory material 2 to cut into its characterized in that: the door opening 4 is positioned in the center of the partition wall 1, and the door opening 4 is a non-arched door opening.
Preferably, the door opening 4 is 970mm high and 450mm wide.
Preferably, the refractory 2 is magnesite-chrome brick.
Preferably, the gap bridge 3 is a rectangular refractory brick with the length of 700mm and the width of 150 mm.
Compared with the prior art, the utility model has the beneficial effects that: the partition wall channel of the silver furnace is simpler than the original partition wall channel and has high reliability, can withstand the scouring of high-temperature melt and smoke in the furnace, has long service life and low maintenance cost, and basically keeps intact after entering the furnace for observation during maintenance.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described below with reference to the accompanying drawings and examples:
example 1
A partition wall channel of a silver furnace comprises a partition wall 1, a door opening 4 and a gap bridge rotor 3, wherein a copper water jacket 5 is arranged at the top of the partition wall 1, the copper water jacket 5 is cut by a refractory material 2, the door opening 4 is positioned at the center of the partition wall 1, and the door opening 4 is a non-arched door opening.
The door opening 4 is 970mm high and 450mm wide.
The refractory material 2 is magnesia-chrome brick.
The gap bridge rotor 3 is a rectangular refractory brick with the length of 700mm and the width of 150 mm.
The middle partition wall vertical to the furnace wall is built, a passage with the height of 970mm and the width of 450mm is reserved at the center of the partition wall, an arch door opening above the original passage is eliminated, refractory bricks with the length of 700mm and the width of 150mm are built above the passage of the partition wall through a bridge, and 9 refractory bricks with the length of 700mm and the width of 150mm are built totally. The masonry mode is simpler than the original masonry mode and has high reliability. The operation for more than one year shows that the partition wall channel built by the building method can withstand the scouring of high-temperature melt and smoke in the furnace, and the partition wall channel built by the building method is basically kept intact after the partition wall channel enters the furnace for observation during maintenance, so that the service life of the silver furnace is effectively prolonged, and the maintenance cost is reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
