Abstract
The utility model discloses a limestone storage device which comprises a bracket, wherein a barrel body is arranged on the bracket; the upper end of the barrel body is rotatablely provided with a sealing press cover, and the lower end of the barrel body is provided with an integral funnel; an opening of the funnel is rotatablely provided with a bottom plate; the side wall of the funnel is provided with a discharge pipe; and a discharge device is rotatablely arranged at an opening of the discharge pipe. The limestone storage device is simple and reasonable in structural design; and the sealing press cover arranged above the barrel body is effectively matched with the bottom plate and the discharge device which are arranged under the funnel, so that the contact area between limestone and air is effectively reduced, the failure deterioration rate of the limestone is reduced, and the cost is saved.
Description
Technical field:
The utility model relates to the steelmaking ingredient technical field of memory, relates in particular to a kind of limestone memory storage.
Background technology:
The method of steel-making generally can be divided into pneumatic steelmaking, open hearth steelmaking and three kinds of methods of electric furnace steel making.
Air that the oxidizer that open hearth steelmaking uses feeds and the oxide in the furnace charge, (scrap iron, steel scrap, iron ore).Reacting required heat is to be provided by burning gases fuel (blast furnace gas, generator gas) or liquid fuel (heavy oil).
The used raw material of open hearth steelmaking has steel scrap, scrap iron, iron ore and solvent (limestone and quick lime).When beginning to smelt, the hot air that fuel runs into importing just burns on the fuel face, and temperature is up to 1800 degrees centigrade.Heat is directly passed to furnace charge by flame, makes furnace charge melt (fusing point of iron is 1535 degrees centigrade, and steel is lower slightly) rapidly.The pig iron of some fusing simultaneously generates ferrous oxide, the impurity silicon in the pig iron, the oxidized ferrous oxidation of manganese, and sound becomes slag.Because be placed with excessive limestone in the stove, impurity such as phosphorus and sulphur just generate calcium phosphate and calcium sulfide becomes slag.Secondly carbon also carries out oxidation, generates carbonic oxide and in molten metal, emerges, and seems that metal is in boiling.
Storage for limestone is unreasonable, very easily contacts with air, causes the limestone deterioration failure.
The utility model content:
To the deficiency of prior art, a kind of limestone memory storage of the purpose of the utility model, the structure design advantages of simple has reduced the deterioration failure rate of limestone effectively, has practiced thrift cost.
The technical scheme of the utility model is following:
The limestone memory storage; Comprise support, it is characterized in that: on the described support cylindrical shell is installed, the cylindrical shell upper end is rotatablely equipped with gland cover; The cylindrical shell lower end is provided with integrated funnel; The funnel oral area is rotatablely equipped with base plate, on the described hopper side walls discharge nozzle is installed, and the discharge nozzle oral area is rotatablely equipped with discharging device.
Described limestone memory storage is characterized in that: described discharging device includes arc, and the arc both sides are welded with fan-shaped side plate, and the homonymy of arc and side plate is equipped with baffle plate.
The utility model has the advantages that:
The utility model structure design advantages of simple is carried out the actv. cooperation through the gland cover of cylindrical shell top and the base plate and the discharging device of funnel below, and actv. reduces the contact surface with air, has reduced the inefficacy deterioration rate of limestone, has practiced thrift cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
Referring to Fig. 1:
The limestone memory storage comprises support 1, and cylindrical shell 2 is installed on the support 1; Cylindrical shell 2 upper ends are rotatablely equipped with gland cover 3; Cylindrical shell 2 lower ends are provided with integrated funnel 4, and funnel 4 oral areas are rotatablely equipped with base plate 5, but the rotary bottom plate at high speed carries out a large amount of blowings; On funnel 4 sidewalls discharge nozzle 6 is installed, discharge nozzle 6 oral areas are rotatablely equipped with discharging device.
Discharging device includes arc 7, and arc 7 both sides are welded with fan-shaped side plate 8, and arc 7 is equipped with baffle plate 9 with the homonymy of side plate 8, when needs use, can carry out a spot of blowing quickly and easily.
