Description
Technical field
The utility model belongs to ferroalloy technical field of environment protection equipment, and in particular to a kind of mineral hot furnace stokehold exhaust fume collecting hood.
Background technique
With the fast development of ferroalloy enterprise, the ferroalloy industry it is increasingly competitive, in order to make in industry competition
It can establish oneself in an unassailable position, the ferroalloy industry, which constantly improves technological parameter, equipment performance carrys out depositing dust prevents flue gas excessive, reduces
Uncontrollable discharge.In The Sub-mergedfurnace of The Ferroalloys stokehold exhaust fume collecting hood tradition is the steel plate welded framework structure of refractory single with knotting,
Stokehold exhaust fume collecting hood is in long-term production, by the baking of high temperature liquid iron, causes the deformation of steel plate welded framework to increase and there are gap,
Phenomena such as refractory material falls off.High-temperature flue gas is overflowed from gap location, uncontrollable discharge occurs, generates smoke pollution.Traditional furnace
Preceding exhaust fume collecting hood service life is short, maintenance cost is high, environmentally friendly not up to standard, strong influence mineral hot furnace dust removing effects and safe operation
Ability operates normally to enterprise and brings very huge economic loss.
Utility model content
The purpose of the utility model is to provide a kind of mineral hot furnace stokehold exhaust fume collecting hoods, to solve existing apparatus skeleton at high temperature
Easily-deformable that refractory material is caused to fall off, high-temperature flue gas overflows, and the service life is short, pollutes environment, more than maintenance cost height and security risk
Problem.
In order to achieve the above object, the technical solution adopted in the utility model are as follows:
A kind of mineral hot furnace stokehold exhaust fume collecting hood, including preceding exhaust fume collecting hood frame and flame retardant coating, the preceding exhaust fume collecting hood frame include outer
Frame layer and supporting layer, outer frame layer are inverse u shape structure, and flame retardant coating is set in outer frame layer, and supporting layer includes several I-steel,
One end of I-steel is fixedly connected with outer frame layer, and the other end is fixedly connected with flame retardant coating.
The width of the flame retardant coating is less than the width of outer frame layer, has cavity between flame retardant coating and outer frame layer.
The flame retardant coating it is in uneven thickness, between adjacent I-steel the thickness of flame retardant coating be greater than with the end of I-steel it is straight
Connect the thickness of junction flame retardant coating.
There is gap between the flame retardant coating and the vertical bar of I-steel.
The bottom of the flame retardant coating is higher than the bottom of outer frame layer.
The outer frame layer is channel steel material.
The flame retardant coating is lightweight opposite sex refractory brick material.
The utility model having the beneficial effect that compared to the prior art
The frame structure that the channel steel of outer frame layer and I-steel form is directly welded on furnace shell by the utility model, non-integral
Plate structure is unlikely to deform, and lightweight opposite sex refractory brick is inlaid into the frame structure, and between outer frame layer and flame retardant coating
Cavity is set, the bottom of flame retardant coating is elevated to the bottom of outer frame layer, can be conducive to air inflow and circulation, effectively improve every
Thermal effect, flame retardant coating can reduce exhaust fume collecting hood weight and deflection, flame retardant coating and I-steel using lightweight opposite sex refractory brick material
Vertical bar between setting gap I-steel deformation can be effectively prevented under fortuitous event, flame retardant coating is caused to squeeze and fall off.
The utility model resistance to deformation, long service life, heat insulation, good seal performance, structure are simply easy to maintain.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Appended drawing reference meaning is as follows: 1, flame retardant coating；2, outer frame layer；3, I-steel；4, cavity；5, gap；6, furnace shell；7, go out
Iron mouth.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of mineral hot furnace stokehold exhaust fume collecting hood, including preceding exhaust fume collecting hood frame and flame retardant coating 1, the preceding exhaust fume collecting hood
Frame includes outer frame layer 2 and supporting layer, and outer frame layer 2 is inverse u shape structure, and flame retardant coating 1 is set in outer frame layer 2, supporting layer packet
Several I-steel 3 are included, one end of I-steel 3 is fixedly connected with outer frame layer 2, and the other end is fixedly connected with flame retardant coating 1.
The width of the flame retardant coating 1 is less than the width of outer frame layer 2, has cavity 4 between flame retardant coating 1 and outer frame layer 2.
The flame retardant coating 1 it is in uneven thickness, the thickness of flame retardant coating 1 is greater than end with I-steel 3 between adjacent I-steel 3
Portion is directly connected to the thickness of place's flame retardant coating 1.
There is gap 5 between the flame retardant coating 1 and the vertical bar of I-steel 3.
The bottom of the flame retardant coating 1 is higher than the bottom of outer frame layer 2.
The outer frame layer 2 is channel steel material.
The flame retardant coating 1 is lightweight opposite sex refractory brick material.
Before operation, first outer frame layer 2 and I-steel 3 is welded on the furnace shell 6 of 7 periphery of tapping hole and forms it into preceding exhaust fume collecting hood
Frame, and one end of I-steel 3 and the channel steel of outer frame layer 2 are welded together, then in I-steel 3 far from outer frame layer 2 one
Built at end into lightweight opposite sex refractory brick, and do thickening processing between adjacent I-steel 3, need flame retardant coating 1 and outer frame layer 2 it
Between reserve cavity 4, reserve ground clearance between flame retardant coating 1 and ground, and the vertical bar that cannot be close to I-steel 3 is built into needing
There are gaps 5.
When operation, molten iron flows into ladle by tapping hole 7, and the high-temperature flue gas that molten iron is taken out of is i.e. by the lightweight of flame retardant coating 1
Anisotropic refractory brick stops, and since the frame structure that I-steel and outer frame layer are formed is used as support, is unlikely to deform, reaches preferable
Heat insulation.
