Description
Technical field
This application involves converter, the processing of electric furnace hot melt steel slag, especially a kind of cooling equipment of hot melt steel slag dry method.
Background technique
Steel slag as the trade waste generated in steel manufacture process, be belong to national regulation a kind of industrial solid it is useless
Gurry, discharge amount is big and effect on environment seriously annoyings always enterprise, how to carry out handling and utilizes these wastes
Become steel, building materials enterprise urgent problem instantly.
Therefore, " environmental protection tax law " and " People's Republic of China's solid that country came into effect on January 1st, 2018
The anti-therapy of waste pollution environment " legislation management is carried out to industrial solid castoff, encourage enterprise innovation to utilize, optimization production.
Present hot melt slag processing mode both domestic and external is divided into bored slag method, drum process, wind crush method, water quenching, hot application method, cold
Abandoning method and tray method etc..It is that steel slag is cooled to environment temperature from liquid, molten state or high-temperature solid using water as cooling media
Degree.The prior art can be narrow using face, can not accomplish that stage construction, staged utilize；Also, high-temperature steam dust-laden is easy to produce greatly
Secondary pollution damages greatly downstream waste heat utilization equipment, and the loss of Water Energy is serious, has drawn high processing cost on the whole.
After traditional water cooling of high-temperature steel slag, UTILIZATION OF VESIDUAL HEAT IN is carried out, is not possible to accomplish pure use, it is serious to restrict
Waste heat directly or indirectly uses approach.By the cooling high-temperature steam collected, there is also very big in conversion process of energy
Loss and environmental pollution cause it to utilize low.
The heat of steel slag can be exchanged into hot wind using air cooling system by the application.Hot wind can be directly using as baking
Dry medium can also be heated into hot water with indirect utilization or be heated to form steam, directly utilization or steam-electric power.This system is closing
The dust of system, generation is recycled with bagroom, can be used for the raw material of steel-making slag powder.
Summary of the invention
In view of current processing hot melt steel slag using water as on the technological layer of the processing mode of cooling media, the application is proposed
A kind of cooling equipment of hot melt steel slag dry method.
The technical solution for the technical issues of the application solves is: a kind of cooling equipment of hot melt steel slag dry method, which is characterized in that
The transmission mechanism include one group of driving wheel and have multiple container containings it is hinged made of conveyer belt；The slag charge turning machine
Structure, including ratchet and tire；The top of transport mechanism is arranged in the turning mechanism.
Further, the cooling equipment further includes cooling duct, cloth-bag type dust collection equipment and closed recuperation of heat channel.
Further, the slag charge container containing is several arrangements, hingedly forms, continuous to transmit.
Further, the slag charge turning mechanism is the ratchet device of rotation, and the tire and wheel body of ratchet surface are hinged, and
And it can only be swung to bending direction；The ratchet device is mounted on above slag charge container containing, the tire on ratchet device surface
It is contacted with the slag charge on container containing.
Further, ratchet device direction of rotation when stirring slag charge is consistent with container containing direction of transfer.
Further, the both ends for the conveyer belt that container containing is hinged together are arranged in the transmission mechanism, are slag charge cold
But device transmission provides power.
Further, it when the steel slag particle after screening is poured onto the feeding inlet of cooling device by the transfer tool, contains
Container passes through the cooling duct of high speed jet airstream with steel slag, and cooling duct is in barotropic state.
Further, the tail portion of cooling duct is arranged in the recuperation of heat channel, and recuperation of heat channel is equipped with cloth-bag type dust suction
Equipment carries out dust suction purified treatment to the high-temperature hot air for the heating that cooling duct is sent, is re-fed into using port.
Further, the front end using port is equipped with powerful air delivery pump, maintains the negative pressure shape in recuperation of heat channel
State.
Further, the use port is equipped with slag charge drying port, sea water desalination port or cogeneration port.
Detailed description of the invention:
It in order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below will be to embodiment or existing skill
Attached drawing needed in art description is briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention
Some embodiments for those of ordinary skill in the art without any creative labor, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is the operation schematic diagram of cooling device of the invention.
In Fig. 1: 1- ratchet device, 2- slag charge container containing, 3- driving wheel.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carry out it is clear,
It is fully described by, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.
Based on the embodiments of the present invention, those skilled in the art are obtained under the premise of not making creative labor
Every other embodiment belongs to the range that the present invention is protected.
Firstly, the present invention proposes a kind of cooling equipment of hot melt steel slag dry method, steel slag smashed to pieces using machinery become equal to or
Person is less than the steel slag block of 150mm, is delivered to particle screen selecting equipment, and the steel slag particle of 150mm is greater than by filtering out, and slag is held in return
Platform continues to smash to pieces；Steel slag particle equal to or less than 150mm is passed in the cooling equipment of steel slag by transporting trolley.
Secondly, the steel slag into the cooling equipment of steel slag is poured into container containing, the ratchet device being located above stirs Sheng
Slag charge inside packaging container keeps it quick, uniformly cooling, and container containing contains slag charge and is sent to out by Fast Cooling channel
Cinder notch does subsequent processing.
Furthermore by the cold air of cooling duct, after being heated by high-temperature steel slag, becomes high-temperature hot air and enter hot-air receipts
Collect channel and is assigned to UTILIZATION OF VESIDUAL HEAT IN ports at different levels according to calorific value gradient.
