Description
Technical field
The present invention relates to hot blast furnace process field, especially a kind of high titania type molten blast furnace slag hot charging enters furnace apparatus.
Background technique
At present at home and abroad there is no the precedent that thermal-state blast furnace slag enters furnace smelting, thermal-state blast furnace slag transports carbon by slag ladle and carriage
Change workshop, due to equipment installation requirement, blast furnace slag cannot directly be poured into carbide furnace by slag ladle and carriage, and blast furnace slag has
1300 DEG C or more of high temperature, is in a liquid state, and liquid blast furnace can be splashed on surrounding devices during being poured directly into furnace, can be right
Other equipment cause serious influence, and there are security risks.Carbide furnace needs closed smelting to guarantee coal gas in smelting process
Recycling and the high requirement of the thermal efficiency, cannot be sealed using common chute in carbide furnace material receiving port, or directly topple over needs and open
Bell cannot be guaranteed to seal, and switch seal lid needs manual operation, and difficulty is big, dangerous.
This high titania type molten blast furnace slag hot charging enters furnace method and device and is mainly used in hot height in high temperature cabonization engineering
Clinker enters carbide furnace process.In order to reduce production energy consumption, need to pour into carbide furnace through thermal-state blast furnace slag and cannot be to carbide furnace
Equipment impacts, therefore the use of sealing device is an ideal scheme by thermal-state blast furnace slag importing carbide furnace, can
Guarantee that the safety of thermal-state blast furnace slag enters carbide furnace, in turn avoids directly causing carbide furnace thermal-state blast furnace slag importing carbide furnace
The problem of enormous impact and guarantee carbide furnace realize closed smelting.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of slag notches that effectively solves to be blocked, to guarantee hot height
The safety of clinker enters carbide furnace, in turn avoids that thermal-state blast furnace slag importing carbide furnace is directly caused enormous impact to carbide furnace
High titania type molten blast furnace slag hot charging enters furnace apparatus.
The technical solution adopted by the present invention to solve the technical problems is: high titania type molten blast furnace slag hot charging enters furnace apparatus,
Including device noumenon, described device ontology includes warm sludge entrance, slag notch and the gate sealing dress being set in device noumenon
It sets, the gate sealing device is sealed slag notch and being close to slag notch, wherein the warm sludge inlet is provided with slash
Slag plate structure.
Further, the skimming plate structure is the fenestral fabric being made of skimming plate.
Further, the gate sealing device is made of hydraulic cylinder, guiding device and gate.
Further, the gate sealing device is to be arranged in a vertical direction.
The beneficial effects of the present invention are: when thermal-state blast furnace slag transports carbonization workshop by slag ladle and carriage, directly by blast furnace
Slag is poured into furnace apparatus, has skimming plate structure due to entering furnace apparatus entrance, and due to gravity, the slag body and skimming plate of bulk
Structural impact is decomposed into the slag body of fritter immediately, to solve the problems, such as that slag notch is easy to be blocked.When retort dress slag is complete
Bi Hou, gate sealing device can guarantee the tight requirements of retort.The configuration of the present invention is simple, easy to operate, purchase cost is low
It is honest and clean, it can be widely applied to the place that the industries such as metallurgy, chemical industry need to pour into fluid, be particularly suitable for the input field of the slag body of bulk
It closes.
Detailed description of the invention
Fig. 1 is main view of the invention.
Fig. 2 is top view of the invention.
Fig. 3 is side view of the invention.
In the figure, it is marked as warm sludge entrance 1, hydraulic cylinder 2, guiding device 3, device noumenon 4, gate 5, slag notch 6, skimming plate
Structure 7.
Specific embodiment
The following further describes the present invention with reference to the drawings.
High titania type molten blast furnace slag hot charging as shown in Figure 1, Figure 2, Figure 3 shows enters furnace apparatus, including device noumenon 4, the dress
Setting ontology 4 includes warm sludge entrance 1, slag notch 6 and the gate sealing device being set in device noumenon 4, the gate sealing
Device is sealed slag notch 6 and being close to slag notch 6, wherein is provided with skimming plate structure 7 at the warm sludge entrance 1.
In actual use, in order to reduce production energy consumption, need to pour into thermal-state blast furnace slag carbide furnace and cannot be to carbonization
Furnace apparatus impacts, thus using have sealing function enter furnace apparatus by thermal-state blast furnace slag importing carbide furnace be one very
Ideal scheme both can guarantee that the safety of thermal-state blast furnace slag entered carbide furnace in this way, and in turn avoid directly leading thermal-state blast furnace slag
Enter the problem of carbide furnace causes enormous impact to carbide furnace and guarantees that carbide furnace realizes closed smelting.It is first when specific operation
First blast furnace slag is poured into from warm sludge entrance 1, due to there is the shielding of device noumenon 4, the when of falling slag slag liquid will not splashes,
Thus to surrounding devices by protective effect.After shove charge, gate sealing device seals slag notch 6, guarantees retort smelting
Tight requirements when refining.
In order to realize the ideal crushing effect of slag body to bulk, as shown in Figure 2, the skimming plate structure 7 can be selected
It is selected as the fenestral fabric being made of skimming plate, it is broken so as to more evenly, more effectively realize.
In order to simplify structure as far as possible under the premise of guaranteeing gate sealing device function, thus reduce the manufacturing at
This, can choose such scheme: the gate sealing device is made of hydraulic cylinder 2, guiding device 3 and gate 5.Hydraulic cylinder 2
Gate 5 is driven to be sealed slag notch 6 by guiding device 3.Generally, the gate sealing device is cloth along the vertical direction
It sets.
When thermal-state blast furnace slag transports carbonization workshop by slag ladle and carriage, directly blast furnace slag is poured into furnace apparatus, due to
Entering furnace apparatus entrance has skimming plate structure, and due to gravity, slag body and the skimming plate structural impact of bulk are decomposed into immediately
The slag body of fritter, to solve the problems, such as that slag notch is easy to be blocked.After retort fills slag, gate sealing device can
To guarantee the tight requirements of retort.The configuration of the present invention is simple, easy to operate, purchase cost is cheap, can be widely applied to metallurgy,
The industries such as chemical industry need to pour into the place of fluid, are particularly suitable for the input occasion of the slag body of bulk.
