Abstract
The utility model discloses a buffer tank for treating granulated slag by a rotary drum equipment component, which belongs to the field of slag treatment equipment and comprises a tank body with a lifting lug, wherein a buffer beam is fixedly arranged in the tank body; the ventral side of the lining plate is detachably connected with the alumina ceramic plate; an epoxy resin glue layer is arranged between the ventral side of the lining plate and the alumina ceramic plate. Compared with the prior art, the service life of the blast furnace buffer tank can be prolonged, and cost and efficiency are reduced.
Description
Technical Field
The utility model relates to slag treatment equipment, in particular to a granulated slag treatment buffer tank suitable for blast furnace granulated slag treatment in an iron-making plant.
Background
The water granulated slag treatment buffer tank is an important slag treatment device for blast furnace water granulated slag in iron works. A large amount of water slag is generated in blast furnace iron making, the water slag which just flows out of the molten iron separator is in a high-temperature liquid state, and the water slag can be changed into the water slag only by washing and cooling through a washing tower and enters a water slag separation system through a slag pipeline. Then enters the belt through the slag extracting device and is transported to a cement plant to generate value. If any link of slag treatment has a problem, the high-temperature liquid granulated slag is directly discharged into a slag pool, and the high-temperature liquid granulated slag which is not subjected to water treatment is changed into fire slag, so that the value cannot be generated, and a large amount of manpower and material resources are wasted for cleaning the fire slag. In actual production, the grain slag treatment equipment is frequently corroded seriously and is worn to leak, and the slag treatment equipment needs to be replaced at the moment.
At present, the slag flushing buffer box body is made of delta 20 manganese plates by processing and riveting, and no wear-resisting measure is provided. And the baffle-box mainly bears the high temperature sulfidation corrosion and the wearing and tearing of incasement water and sediment are strikeed at the operation in-process, because of operational environment is abominable, the baffle-box life-span is at most a year, and the baffle-box of rolling off the production line corrodes, wearing and tearing are serious, and bumper beam and box part have all worn through, can only shut down to overhaul and scrap the processing. Because the baffle-box is located the narrow and small position in space in the rotary drum, all the time is the maintenance that takes up a long time in overhauing, needs a large amount of manpower and materials, influences the blast furnace and overhauls the progress. And the rotary drum and other accessories are damaged together after the box body is damaged, so that the resource waste is serious, the environmental pollution is serious, and the product manufacturing period is long.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide the buffer tank for treating the grain slag by the rotary drum equipment component, aiming at the defects of the prior art, effectively prolonging the service life of the buffer tank, solving the phenomenon of short online service life of the slag flushing buffer tank and effectively reducing the maintenance time and the maintenance cost.
The technical scheme for solving the technical problem is as follows: the utility model provides a buffer tank of rotary drum equipment subassembly processing grain sediment, is including the box that has the lug, and fixed mounting has the bumper beam in the box, the box include curb plate, end plate, bottom plate and last shrouding, its characterized in that: the back sides of the lining plates are detachably connected with the inner surface of the box body or the upper surface of the buffer beam; the ventral side of the lining plate is detachably connected with the alumina ceramic plate; an epoxy resin glue layer is arranged between the ventral side of the lining plate and the alumina ceramic plate.
The back side of the lining plate is connected with the inner surface of the box body or the upper surface of the buffer beam through M20 bolts and nuts.
The ventral side of the lining plate is connected with the alumina ceramic plate M10 through bolts.
Compared with the prior art, the utility model has the following outstanding beneficial effects:
1. the abrasion resistance of the lining plate of the buffer box is effectively improved, the lining plate can be continuously on-line after being simply cleaned, the on-line time is 3 times of that of the original buffer box, the equipment cost is greatly saved, and the cost is reduced and the efficiency is improved;
2. the modularized assembly reduces the maintenance time, reduces the repeated manufacturing process, shortens the production period and improves the grain slag treatment efficiency.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic sectional view taken along line a-a of fig. 1.
Fig. 3 is a schematic view of the liner installation.
Detailed Description
The utility model is further described with reference to the drawings and the detailed description. For better description, the direction toward the granulated slag is the ventral side, and vice versa.
As shown in figures 1-3, the utility model comprises a box body 2 with a lifting lug 1, and a bumper beam 5 is fixedly arranged in the box body 2. The box body 2 comprises side plates, end plates, a bottom plate and an upper sealing plate.
The box body is characterized by further comprising a plurality of lining plates 3, wherein the back sides of the lining plates 3 are connected with the inner surface of the box body 2 or the upper surface of the buffer beam 5 through M20 bolts and nuts 6. The ventral side of the lining plate 3 is connected with the alumina ceramic plate 4 through M10 bolts 7. An epoxy resin glue layer 8 is arranged between the ventral side of the lining plate 3 and the alumina ceramic plate 4.
In the optimized scheme, the inner surface of the box body 2 below the bumper beam 5 and the inner surface of the upper closing plate of the box body 2 are not connected with the lining plate 3.
When the slag flushing buffer box is actually operated, firstly, the aluminum oxide ceramic is subjected to abrasion impact, the machine can be stopped and maintained until the aluminum oxide ceramic is damaged, only the bolt needs to be unscrewed during maintenance, the new wear-resistant ceramic lining plate is replaced, the slag flushing buffer box can be ensured to be continuously used, in the whole process, the slag flushing buffer box shell is not subjected to impact abrasion, the high wear resistance and the corrosion resistance of the aluminum oxide ceramic are utilized, the service life is greatly prolonged, the material is about 3 times of the original design, the machine halt maintenance time is shortened by utilizing the wear-resistant ceramic lining plate in the bolt connection mode, the service life of the slag flushing buffer box is prolonged, the damage manufacturing period and the cost of the slag flushing buffer box are reduced, and the important significance is realized on energy conservation, consumption reduction and labor intensity reduction.
It should be noted that while the utility model has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the utility model.
