Abstract
The utility model relates to a charging device of a blast furnace top, in particular to an ultra-low charging device of a blast furnace and the furnace top with no charging bell. The charging box of the device replaces the original receiving hopper and the charging valve, and can not only meet the charging and driving needs of the iron-smelting technology of the blast furnace, but also can decrease the height of the charging equipment of the furnace top obviously, thereby being particularly applicable to rebuild the old blast furnace into the charging device of the furnace top with no charging bell; the charging device can accept charging from various charging systems such as a belt charging or a skip charging, thereby simplifying the structure and keeping the operation and control convenient under the conditions of meeting the technology needs.
Description
Technical field
The utility model belongs to blast furnace top charging technical field, relates to a kind of blast furnace top charging device, particularly a kind of ultralow type blast furnace bell-less top charging device.
Background technology
At present both at home and abroad the loading device of blast furnace mainly contains two big classes, a class has bell, and another kind of is no bell.Domestic blast furnace ironmaking adopts non-bell furnace top charging equipment comparatively general, in nearly ten years, and domestic 750m
3More than newly-built blast furnace nearly all adopt no bell top charging.And the requirement of smelting along with process strengthening, in recent years, 300 newly-built～450m
3The blast furnace of level also has a lot of no bell furnace roofs that adopted.Some do not reach the old clock-type furnace roof blast furnace that overhaul is rebuild as yet, owing to be subjected to the restriction of its original furnace roof skew bridge height and conveyor height, can not adopt domestic present advanced person's no bell furnace roof technology.
Domestic several no bell furnace roof commonly used can be divided into: tandem tank type and and pot type, no matter be tandem tank type or and the pot type structure,---baiting valve 9---upper sealing valve 1---batch can 2---throttling valve 3---lower seal valve 4---ripple compensation 5---distributor 6 of all forming (seeing shown in Figure 1): hopper 8 by following components.As shown in Figure 1, typical its principle of work of tandem tank type installation for charging shaft furnace is, when hopper 8 is accepted a certain amount of material, according to the processing sequence requirement, open 3～5 seconds of upper sealing valve 1 time-delay earlier after, open baiting valve 9, this moment, hopper 8 interior materials entered batch can 2, when material all enters batch can 2 in the hopper 8, closed baiting valve 9, hopper 8 prepares to accept the next batch material, and this moment, batch can 2 interior materials required to be put into blast furnace equably by distributor according to technology controlling and process.The feeder of above-mentioned this structure after hopper 8 receives the material of certain batch, just can be opened baiting valve 9, and material is put into batch can 2.In order to satisfy requirement reinforced on the technology, hopper 8 is generally done very big very highly, adds the height of baiting valve 9, and for a small furnace, the height of feeder will increase about 3 meters at least.And can not feeding in continuous material, can only accept material, blowing more a collection ofly, cycle operation is not suitable for using the feeding in continuous material system.Particularly limit large quantities of old blast furnaces and can not be transformed into advanced no bell top charging device.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of ultralow type blast furnace bell-less top charging device is provided.
In order to reach above-mentioned purpose, a kind of ultralow type blast furnace bell-less top charging device that the utility model provides, comprise upper sealing valve, batch can, throttling valve, lower seal valve, ripple compensation, distributor, a low moulding mixture groove is installed on top at described upper sealing valve, this hopper is the bucket type, its suitable for reading opening wide, the end opening of hopper and the open communication of upper sealing valve.
Described hopper upper shed forms a domatic material receiving port towards the position of feeding system, so that accept material.
The utility model compared with prior art has the following advantages:
This device is owing to substituted the material loading part of former cause hopper and baiting valve composition with ultralow moulding mixture groove, the height of top charging equipment obviously reduces, be specially adapted to old blast furnace reformation and become no bell top charging device, it can accept various feeding system material loadings, as charge hoisting by belt conveyer or truck material loading.Satisfying the processing requirement charging, catching up with under the condition of material, simplified device structure, be convenient to operation control.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described.
As shown in Figure 2, the utility model provides a kind of ultralow type blast furnace bell-less top charging device, comprise upper sealing valve 1, batch can 2, throttling valve 3, lower seal valve 4, ripple compensation 5, distributor 6, wherein, a low moulding mixture groove 7 is installed on top at upper sealing valve 1, hopper 7 is the bucket type, its suitable for reading opening wide, and the end opening of hopper 7 is connected with the opening of upper sealing valve 1.
Described hopper 7 upper sheds form a domatic material receiving port 71 towards the position of feeding system, so that accept material.
In the present embodiment, feeding system is selected the charge hoisting by belt conveyer system.When charge hoisting by belt conveyer system during to the furnace roof feeding, upper sealing valve 1 is opened, and material is sent in the hopper 7 from domatic interface 71 by the charge hoisting by belt conveyer system, and material is directly entered in the batch can 2 by upper sealing valve 1 through hopper 7, when the material that adds in the batch can 2 reaches processing requirement, close upper sealing valve 1, batch can 2 blowings, and the hopper 7 of this moment still can continue to accept material, after finishing, batch can 2 blowings open upper sealing valve 1, batch can 2 enters the material state of accepting again, with this cycle operation, satisfies the blast furnace technology requirement.
For 300～2000m
3Blast furnace, through calculating proof, no matter the ultralow type blast furnace bell-less top charging device that uses the utility model to provide is to adopt charge hoisting by belt conveyer system or truck material loading, all the processing requirement that can satisfy charging, catch up with material.For large quantities of small furnaces and old blast furnace, the utility model has solved them and has transform the problem of the technology and equipment of no bell top charging as, and cost is low, effective.
