Description
Technical field
The utility model is specifically related to a kind of blast furnace and changes tuyere medium sleeve new device.
Background technology
In metallurgy industry, the air-intake device of blast furnace is made up of tuyere big sleeve, middle set, small set and belly pipe.In height
In stove production, because various raw material and fuel qualities are unstable and working of a furnace fluctuation, also tuyere case sole mass reason, blast-furnace tuyere
Set is often burnt and leaked.In order to ensure normal production, it is necessary to which damping down is changed to the tuyere case that changes for burning leakage.Particularly in air port
When set is changed, because middle set volume is larger, the take-down time is long.This is due to the tuyere medium sleeve more changing device knot of prior art
Structure is simple, backward in technique, it is necessary to manually pull sliding hammer back and forth, and pull bar is driven using the shock of sliding hammer, make tuyere medium sleeve movable with
Afterwards, it could be dismantled.Said process needs many people manually operated in turn, is sometimes difficult to disassemble, that is, wastes time, people
Power, material resources, reduce production efficiency again, also unfavorable to keeping the safety in production.
Utility model content
The purpose of the utility model device is to solve prior art tuyere medium sleeve more changing device due to simple in construction, technology
Fall behind, there is the defect that labor intensive is more, waste time and energy during dismounting and change the new dress of tuyere medium sleeve there is provided a kind of blast furnace
Put, its is rational in infrastructure, it is easy to operate, energy-conserving and environment-protective, safety labor-saving, production efficiency can be improved, the work of workman can be reduced again
Intensity, has been correspondingly improved enterprise's productivity effect.
The utility model is achieved by the following technical solution：
I.e. a kind of blast furnace changes tuyere medium sleeve new device, it is characterised in that horizontally disposed very heavy including one
Long stent is fixed in top, one end of jack, and the other end fixes short support, and long stent, short support be arranged in parallel, be each perpendicular to very heavy
Top, short support is located at the outside of long stent, and the side of jack, which is additionally provided with two, covers pull bar, and pull bar is parallel sets for set in two
Put, the rear end that rear end sequentially passes through set pull bar in long beam, tail trimmer, two is equipped with external screw thread, and above-mentioned thread segment sets spiral shell
Mother, the leading inside that the front end of middle set pull bar is provided with set pull bar in the eave tile protruded laterally, two is connected by rotating fixing rod
Be connected together, rotating fixing rod is that set pull bar is provided with matching screwed hole in screw rod, two, rotating fixing rod perpendicular to
Pull bar is covered in two.
Rotating fixing rod of the present utility model plays a part of fixed eave tile, prevents from covering pull bar in when pulling tuyere medium sleeve
Inside lateral bend, causes eave tile to come off, and it can also need to realize that pull bar front end is covered in two is slight by rotating and reverse
Folding.For this, it has following two schemes：
1) whole screw flight direction is identical, provided with rotation nut in the middle part of screw rod, and rotation nut is fixedly connected with screw rod,
The hand of spiral of screwed hole in two on set pull bar is opposite.
2) rotating fixing rod is made up of two opposite screw rods of screw thread, provided with rotation nut in the middle part of two screw rods, rotates spiral shell
Mother is fixedly connected with two screw rods, and the hand of spiral of the screwed hole in two on set pull bar is opposite.
Principle of the present utility model is as follows:
Fixed long stent is fixed at big set outer furnace shell, pull bar is covered in two and hooks air port using eave tile through flange
Middle set both sides, using rotating fixing rod in two cover pull bar be fixed, movable short support covered along along two back end of tie rod to
Front slide, until its inner side and very heavy top contact, movable short support is fixed, then start jack, push up it using nut
Bar is outwards ejected, and push rod pulls tuyere medium sleeve by covering pull bar in movable short support, two, is unloaded.
The utility model has rational in infrastructure, easily operated, energy-conserving and environment-protective, the advantage of safety labor-saving.It is new using this practicality
Type tuyere medium sleeve more changing device compared with prior art, shortens and changes the tuyere medium sleeve time, and set can shift to an earlier date 3-4 hour in one, section
Workman's muscle power is saved, it is important that safety and environmental protection, has been that blast furnace replies immediately wind and creates condition soon, improves productivity effect notable.
Brief description of the drawings
Fig. 1 is the structural representation of prior art tuyere medium sleeve more changing device；
Fig. 2 is structural representation of the present utility model.
As shown in FIG.：1. rotating fixing rod；2. in cover pull bar；3. fix long stent；4. jack；5. movable short branch
Frame；6. nut；7. pull bar；8. sliding hammer.
Embodiment
As shown in Figure 1：Technology tuyere medium sleeve changes apparatus structure simply, backward in technique, and it needs artificial pull back and forth to slide
Hammer 8, pull bar 7 is driven using the shock of sliding hammer 8, is made after tuyere medium sleeve activity, could be dismantled.Said process needs many people
It is manually operated in turn, it is sometimes difficult to disassemble, that is, wastes time, human and material resources, production efficiency is reduced again, safety is given birth to
Production is also unfavorable.
