Abstract
The utility model discloses a rotary hearth furnace storage silo, storage silo body both sides are provided with temperature -detecting device respectively, and the top sets up the convulsions dust pelletizing system, and the surface is equipped with the explosion -proof valve of connecting outside pipeline, storage silo body outside sets up two sets ofly around in all around and connected intake pipe, the intake pipe is connected with the inlet manifold, the last trip valve that sets up of inlet manifold, connection control is quick -witted respectively with the trip valve for temperature -detecting device, convulsions dust pelletizing system, pour into the gaseous form of low -temperature stabilization into through the intake pipe, realize storage silo cooling and replacement explosive gases.
Description
Technical field
The utility model belongs to iron and steel processes/manufacture field, relates to a kind of for the DRI finished bin being applied to rotary hearth furnace production line with safeguard protection.
Background technology
The finished product DRI metallized pellet that rotary hearth furnace is smelted has oxidisability, can react and spontaneous combustion with water.DRI finished product in feed bin makes own temperature constantly rise because of heating, when direct-reduced iron runs into water, redox reaction will occur, discharge hydrogen and amount of heat slowly in this reaction, makes to produce explosive mixed gas in feed bin.
Again because be stored in the DRI pelletizing of storage bin, regularly to be given to rubber conveyer by the dosing equipment be arranged under storehouse, then be transported to raw material interface conveyor drive and be sent to blast furnace.Due to the temperature about 200 DEG C of DRI pelletizing when entering feed bin, the conveyor drive conveying under feed bin will ensure that DRI temperature can not exceed the high temperature resistant limit of belt, otherwise can burn out belt.
Utility model content
The purpose of this utility model is to provide a kind of rotary hearth furnace storage bin, is injected the form of cryostatic stabilization gas by inlet pipe, realizes storage bin cooling and displacement explosion gas.
A kind of rotary hearth furnace storage bin that the utility model proposes for its technical problem of solution, storage bin body both sides are respectively arranged with temperature-detecting device, and top arranges ventilation and dust removal system, and surface is provided with the explosion trap connecting external pipe; Storage bin body exterior is around two groups around storage bin body exterior and connected inlet pipe, and described inlet pipe is connected with inlet manifold, and inlet manifold arranges trip valve; Described temperature-detecting device, ventilation and dust removal system and trip valve be connection control machine respectively.After trip valve is opened, then annular gas blow pipe pours nitrogen uniformly by the inlet mouth that circulating line is evenly distributed and carries out cooling and replacing explosion gas in feed bin, realizes safety in production.During use, trip valve controls opening of trip valve by the real time temperature measured by the temperature-detecting device on storage bin, temperature-detecting device generally arranges three, be crisscross arranged respectively in storage bin upper, in and bottom, as long as temperature detection has a temperature more than 250 DEG C, then open electronic trip valve and pour nitrogen in storage bin.
Storage bin body transverse section is rounded, and be convenient to inlet pipe arrangement, annular intake pipe is arranged at middle part and the bottom of storage bin body respectively, its inlet mouth arranges several, be uniformly distributed in around storage bin body, be conducive to overall cooling, avoid high temperature explosion gas to be gathered in a place.
Be divided into two branch roads after trip valve on inlet manifold, connect into two tracheaes respectively, the form of series winding inevitably causes two groups of inlet pipe air inputs different, thus the uneven or explosion gas of causing lowering the temperature is replaced insufficient situation and occurred; And pipeline is set by the form of two branch roads, easily temperature in feed bin is reduced, inflammable gas displacement is gone out simultaneously, by temperature-detecting device, temperature in feed bin is measured in real time, when temperature being detected lower than secure setting 200 DEG C, stopping input nitrogen, closing trip valve
Described ventilation and dust removal system has the side, top being arranged at storage bin, the exhaust duct be communicated with storage bin body and be arranged at the blade of its inside, is convenient to discharge dust, avoids the rough sledding generations such as blast.
Explosion trap is arranged at storage bin bodies top, is positioned at exhausting-dusting system side; Such as temperature-detecting device is out of control wait extreme case under, when gas in feed bin reaches finite concentration and temperature, may occur vigorous combustion and blast, the gas sharply expanded can impose severe pressure to feed bin; Now, controlling machine opens explosion trap rapidly, and the pressure of release blast generation fully, can avoid the damage of the equipment such as feed bin.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment

Storage bin body 1 transverse section is rounded, and annular intake pipe 4 is arranged at middle part and the bottom of storage bin body 1 respectively, and its inlet mouth arranges several, is uniformly distributed in around storage bin body 1.
Be divided into two branch roads 5 after trip valve on inlet manifold 3, connect respectively into two tracheaes 4.
Described ventilation and dust removal system 7 has the side, top being arranged at storage bin body 1, the exhaust duct be communicated with storage bin body 1 and be arranged at the blade of its inside.
Explosion trap 8 is arranged at storage bin body 1 top, is positioned at exhausting-dusting system 7 side.
More than show and describe ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
