Utility model content
The shortcoming of prior art in view of the above; the purpose of this utility model is to provide a kind of cooling stave mounting structure with flexible sleeve; prevent that amorphous refractory from leaking into FlexbleJoint inside; the effect that makes FlexbleJoint absorb displacement was lost efficacy, and the weld seam of protection water pipe and wall body is not drawn bad.
For achieving the above object and other relevant objects, the utility model provides a kind of cooling stave mounting structure with flexible sleeve, comprise last furnace shell and be arranged on the cooling stave wall body in furnace shell, on described wall body, be provided with many water pipes, on described furnace shell, offer multiple water pipe holes corresponding with water pipe, multiple FlexbleJoints corresponding with water pipe are installed on the outer wall of this furnace shell, described water pipe is inner to be connected with wall body, outer end is stretched out outside furnace shell and is connected with FlexbleJoint through water pipe hole, described water pipe overcoat has flexible sleeve, this flexible sleeve first end is connected with wall body, the second end stretches out the outer wall of furnace shell along water pipe hole, described FlexbleJoint is enclosed within outside water pipe and flexible sleeve, the first end of this FlexbleJoint is connected with the outer wall of furnace shell, the second end of this FlexbleJoint is connected with water pipe outer end, and this FlexbleJoint is pressed on flexible sleeve on water pipe.
Adopt said structure, a sheathed flexible sleeve outside cooling stave water pipe, flexible sleeve one end is connected on wall body, it is outer connected with FlexbleJoint that the other end extends furnace shell, owing to having good compressible performance at the flexible sleeve of cooling stave water pipe external parcel, it is equivalent to reserve in the outside of water pipe the mobile space of water pipe.In the time of cooling stave expanded by heating; even if flexible sleeve outside is wrapped by refractory materials; water pipe also can move by the compression up and down or left and right of sleeve pipe; the weld seam of protection water pipe and wall body is unlikely to be drawn bad; this cooling stave mounting structure is applicable to install ripple compensation organ pipe to absorb in the cooling stave being out of shape and seal; as copper cooling wall, steel cooling wall etc.
As preferably: described flexible sleeve is made up of rubber, can be resistant to elevated temperatures silicon rubber or viton.
As preferably: described flexible sleeve is made up of soft plastics, by thering is certain elasticity and resistant to elevated temperatures plastics are made.
As preferably: described flexible sleeve and wall body are bonding, can also adopt other fixed forms.
As preferably: described FlexbleJoint two ends respectively with furnace shell outer wall and the welding of water pipe outer end.
As mentioned above; the beneficial effects of the utility model are: this mounting structure both can have been protected the water pipe on cooling stave; can form good sealing to the water pipe hole of last furnace shell again; solve traditional copper cooling wall and easily occurred that amorphous refractory leaks into bellows interior; cause the irremovable problem of water pipe, make the weld seam of water pipe and wall body do not drawn bad, simultaneously simple in structure, easy for installation; can effectively protect cooling stave water pipe, be conducive to the steady running of blast furnace and extend its life-span.

Embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification sheets.
As shown in Figure 1; traditional copper cooling wall mounting structure comprises wall body 1, water pipe 2 and furnace shell 4; on wall body, 1 has welded steel bushing 6; be used for protecting the water pipe 2 of furnace shell inner side; in the time that copper cooling wall is installed; by steel bushing 6, gasket 7 (material is rubber, ceramic fiber etc.) is pressed on furnace shell 4, with the water pipe hole 8 on shutoff furnace shell 4.Due to the mismachining tolerance of furnace shell 4, steel bushing 6, and the installation error of copper cooling wall, amorphous refractory in blast furnace can leak into FlexbleJoint 5 inside along the direction of arrow in figure, water pipe 2 is wrapped by refractory materials, cause FlexbleJoint 5 effects to be lost efficacy, cause the problem of the weld cracking of water pipe 2 and wall body 1.
As shown in Figures 2 and 3, the present embodiment discloses a kind of cooling stave mounting structure with flexible sleeve, comprise last furnace shell 4 and be arranged on the cooling stave wall body 1 in furnace shell 4, on wall body 1, be provided with many water pipes 2, many expressions are at least two, on furnace shell 4, offer multiple water pipe holes 8 corresponding with water pipe 2, on the outer wall (being the huyashi-chuuka (cold chinese-style noodles) of furnace shell 4) of this furnace shell 4, multiple FlexbleJoints 5 corresponding with water pipe 2 are installed, water pipe 2 is inner to be connected with wall body 1, outer end is connected with FlexbleJoint 5 outside furnace shell 4 is stretched out in water pipe hole 8, every water pipe 2 correspondences arrange a FlexbleJoint 5, the every outer all cover of water pipe 2 has a flexible sleeve 3, these flexible sleeve 3 first ends and wall body 1 are bonding, the second end stretches out the outer wall of furnace shell 4 along water pipe hole 8, FlexbleJoint 5 is enclosed within outside water pipe 2 and flexible sleeve 3, the outer wall welding of the first end of this FlexbleJoint 5 and furnace shell 4, the second end of this FlexbleJoint 5 and water pipe 2 outer end welding, and this FlexbleJoint 5 is pressed on flexible sleeve 3 on water pipe 2, flexible sleeve 3 is by sealing between water pipe 2 and FlexbleJoint 5, in this example, flexible sleeve 3 adopts silicone rubber tube, also can use in other embodiments flexible plastic tube, fluorine rubber-pipe etc.
Adopt said structure, cancel steel bushing 6, gasket 7 on cooling stave wall body 1, at flexible sleeve 3 of cooling stave water pipe 2 arranged outside, flexible sleeve 3 one end are bonded on wall body 1, and the other end extends the outer same FlexbleJoint 5 of furnace shell 4 and is connected.Owing to having good compressible performance at the flexible sleeve 3 of cooling stave water pipe 2 outsides parcels, it is equivalent to reserve in the outside of water pipe 2 mobile space of water pipe 2.In the time of cooling stave expanded by heating, even if flexible sleeve 3 outsides are wrapped by refractory materials, water pipe 2 also can move by the compression up and down or left and right of flexible sleeve 3, and the weld seam of protection water pipe 2 and wall body 1 is unlikely to be drawn bad.
