The mixed ore tank is arranged between the sintering ore tanks. A feeding tape machine is arranged on the coke ore tank, and the lower part of the coke ore tank is provided with a feeding and screening plant, a weighing funnel, a feeding tape machine, an ore and coke returning tape machine and a dust-removal system, and is also provided with a transfer station required for transferring and storing crude fuel, a fine ore bin and a fine coke bin facility. The invention has compact technical arrangement, smaller occupation of area, small number of matched equipments, and lower engineering investment, saves time of equipment maintenance and repairing, can easily and integrally control the pollution source such as dust, noise and the like, and is an ideal arrangement method of the coke and ore tank which is shared by two blast furnaces.
Description
Technical field
The invention belongs to metallurgical ironmaking technology field.Disclose a kind of two coke and ore tank systems and merged processing set-up, burnt ore tank systems is stored suitable crude fuel, plays batching and adjusting in guaranteeing the blast furnace stably manufactured, is the main technique facility of blast furnace system.
Background technology
When blast furnace was produced, various crude fuels such as needed coke and agglomerate were transported in the groove of burnt ore deposit by conveyor drive on the groove and store.In the design of routine, the layout of burnt ore deposit groove is corresponding with blast furnace, i.e. every burnt ore tank systems of all corresponding cover of blast furnace.But when two blast furnaces are planned layout simultaneously, every blast furnace designs the burnt ore tank systems of a cover respectively, it is big floor space just to occur, on its dust removal installation, the groove under the groove feed conveyor drive, the burnt conveyor drive of returning mine, transfer point and broken coke bin all need arrange two covers, its gross investment height, failure rate also increases, and installation, maintenance, maintenance and personnel are multiplied, and cost is high naturally.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of burnt ore tank systems to merge processing set-up.The layout of this Jiao ore deposit groove can guarantee two original fuel supplies that the blast furnace stably manufactured is required, can realize in the burnt groove of two blast furnaces that assorted ore deposit is standby each other in the coke and assorted ore deposit groove, in relative time, prolonged the purpose of the period of storage of coke groove and assorted ore deposit groove, and source of pollution such as floor space is few, construction investment is lower, maintenance of the equipment maintenance saves time, dust and noise also are easy to centralized Control, can also realize that the agglomerate classification go into the processing requirement of stove by local arrangement adjustment.Be two the shared burnt ore deposit of blast furnace groove ideal decoration forms.
The present invention is made up of facilities such as coke groove, agglomerate groove, fluxo tank, feeding device, screening plant, weighing device, adhesive tape conveyor, cleaning apparatus, transfer point, fine ore bin and broken coke bins.The agglomerate groove of every blast furnace arranges that separately coke groove and assorted ore deposit groove adopt to merge and arrange.On the groove of burnt ore deposit, be furnished with feed conveyor drive on the groove, equipment such as feed, screening plant, weighing funnel, feed conveyor drive, the burnt conveyor drive of returning mine are housed in the bottom of burnt ore deposit groove, and are provided with the facilities such as transfer point, fine ore bin, coke breeze storehouse of crude fuel transhipment and reservoir need.
Purpose of the present invention realizes in the following way:
The coke groove of two blast furnaces and assorted ore deposit groove adopt to merge one to one and arrange, the agglomerate groove of every blast furnace arranges that separately assorted ore deposit groove and agglomerate groove are arranged in juxtaposition one to one.On the groove of burnt ore deposit, be furnished with feed conveyor drive on the groove, equipment such as feed, screening plant, weighing funnel, feed conveyor drive, the burnt conveyor drive of returning mine are housed in the bottom of burnt ore deposit groove, and are provided with the facilities such as transfer point, fine ore bin, coke breeze storehouse of crude fuel transhipment and reservoir need.
Coke and ore are transported to burnt ore deposit groove by conveyor drive on the groove, and during charging of blast furnace, the crude fuel through sieving (or without sieving processing: as melting Ji etc.) processing enters weighing device to carry out being transported to blast furnace by conveyor drive after the weighing.Powder after the screening is transported to fine ore bin and broken coke bin through the burnt conveyor drive of returning mine, transfer point, and establishes nut coke and small grain size ore deposit recovery measure.
Characteristics of the present invention are: the coke groove and the assorted ore deposit groove of two blast furnaces are merged layout one to one, the agglomerate groove of every blast furnace is arranged separately, assorted ore deposit groove and agglomerate groove are arranged in juxtaposition one to one, can realize in the burnt groove of two blast furnaces that assorted ore deposit is standby each other in the coke and assorted ore deposit groove, in relative time, prolonged the purpose of the period of storage of coke groove and assorted ore deposit groove, its processing set-up is reasonable, unobstructed, compact, floor space is less, number of devices is few, the equipment feed capacity strengthens under the groove, a cover dust-removal system (also can be divided into 2 dedusting subsystems: ore deposit groove dedusting subsystem and burnt groove dedusting subsystem); On the groove under the groove conveyor drive, transfer point, fine ore bin and the broken coke bin of the burnt system of returning mine of feed conveyor drive, return mine burnt conveyor drive and outward transport compare quantity with independent layout and all reduce; Source of pollution such as construction investment is lower, maintenance of the equipment maintenance saves time, dust and noise also are easy to centralized Control, and can realize that the agglomerate classification go into the processing requirement of stove by local arrangement adjustment.Be 2 the shared burnt ore deposit of blast furnace groove ideal decoration forms.
Description of drawings
Fig. 1 is an orthographic plan of the present invention;
