Description
Technical field
This utility model relates to blast-furnace technique field, particularly relate to a kind of clamp device for blast furnace tuyere small sleeve and
Blast furnace tuyere small sleeve.
Background technology
Tuyere small sleeve is the visual plant in blast furnace air inlet system, and its effect is to be sent in blast furnace by hot blast, and air port is little
Set is usually copper, the logical cooling in the inside water cooling.
In blast fumance, tuyere small sleeve occur leaking etc. fault time, need to be replaced in time, normal to realize blast furnace
Production operation.For reducing the damping down activity duration of blast furnace, need to control within 30 minutes replacing construction when changing every time.Mesh
Before, tuyere small sleeve is generally connected with top sub by bolt, and bolt the most often produces corrosion, or suffers dirt
Damage, so the take-down time of bolt is longer, directly affects the replacing efficiency of tuyere small sleeve, therefore, how to improve tuyere small sleeve
Replacing efficiency become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Utility model content
In view of this, this utility model provides a kind of clamp device for blast furnace tuyere small sleeve and blast-furnace tuyere is little
Set, described blast furnace tuyere small sleeve includes described clamp device, and this clamp device is easily installed and dismantles, it is possible to be effectively improved wind
The replacing efficiency of the little set of mouth, advantageously reduces the damping down activity duration of blast furnace.
In order to achieve the above object, the following technical scheme of this utility model offer:
A kind of clamp device for blast furnace tuyere small sleeve, including:
Screw rod, one end of described screw rod has screw thread, and the other end offers wedge shape through hole, and described wedge shape through hole is along described spiral shell
Radially extending of bar；
The nut being connected with described screw flight；
It is arranged in the voussoir in described wedge shape through hole.
Preferably, in above-mentioned clamp device, also include being placed on described screw rod the packing ring abutted with described nut.
A kind of blast furnace tuyere small sleeve, the edge of the flange face that described blast furnace tuyere small sleeve is connected with top sub has out
Mouth through hole, described open hole is used for installing above-mentioned clamp device, and the A/F of described open hole is more than described screw rod
Diameter.
According to technique scheme, in the clamp device that this utility model provides, one end of screw rod has screw thread, uses
In being connected with nut, the other end of screw rod offers wedge shape through hole, is used for wearing voussoir, therefore, if it is desirable to dismounting blast furnace wind
During the little set of mouth, only need to reversely tap (by the small end of voussoir to big extreme direction) voussoir, efficient and convenient, it can be seen that, this reality
By the novel replacing efficiency that can be effectively improved tuyere small sleeve, advantageously reduce the damping down activity duration of blast furnace.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is only
It is embodiment of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, also
Other accompanying drawing can be obtained according to the accompanying drawing provided.
Fig. 1 is the schematic diagram of a kind of clamp device for blast furnace tuyere small sleeve that this utility model embodiment provides；
Fig. 2 is the scheme of installation of a kind of tuyere small sleeve that this utility model embodiment provides.
Figure is labeled as:
1, nut；2, packing ring；3, screw rod；4, voussoir；5, top sub；6, tuyere small sleeve.
Detailed description of the invention
In order to make it easy to understand, the utility model will be further described below in conjunction with the accompanying drawings.
Seeing Fig. 1 and Fig. 2, Fig. 1 is that a kind of fastening for blast furnace tuyere small sleeve that this utility model embodiment provides fills
The schematic diagram put, Fig. 2 is the scheme of installation of a kind of tuyere small sleeve that this utility model embodiment provides.
The clamp device for blast furnace tuyere small sleeve that this utility model embodiment provides includes nut 1, screw rod 3 and voussoir
4, wherein, one end of screw rod 3 has screw thread, and for attaching nut 4, the other end of screw rod 3 offers wedge shape through hole and (do not marks in figure
Note), wedge shape through hole radially extends along screw rod 3, is used for wearing voussoir 4.
In order to prevent nut 4 from loosening as far as possible, the clamp device in the present embodiment also includes being placed on and supports with nut 1 on screw rod 3
The packing ring 2 connect.
After using clamp device of the present utility model that blast furnace tuyere small sleeve is installed, if needing dismounting, only need to reversely tap
(by the small end of voussoir to big extreme direction) voussoir 4, efficient and convenient, it is possible to be effectively improved the replacing efficiency of tuyere small sleeve,
Advantageously reduce the damping down activity duration of blast furnace.
This utility model additionally provides a kind of blast furnace tuyere small sleeve, as in figure 2 it is shown, blast furnace tuyere small sleeve 6 and top sub 5
The edge of the flange face connected has open hole (unmarked in figure), and accordingly, the edge of the flange face of top sub 5 is also
Offer the open hole on open hole, blast furnace tuyere small sleeve 6 and top sub 5 to be used for fastening dress of the present utility model is installed
Putting (see Fig. 1), wherein, the A/F of open hole is more than the diameter of screw rod 3 (see Fig. 1), then, when dismounting clamp device
Time, only need to unscrew nut, then clamp device entirety be taken out from the opening of open hole together, thus it is little to improve air port
The replacing efficiency of set.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this practicality new
Type.Multiple amendment to embodiment will be apparent from for those skilled in the art, as defined herein
General Principle can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Therefore, originally
Utility model is not intended to be limited to embodiment illustrated herein, and is to fit to and principles disclosed herein and features of novelty
The widest consistent scope.
