Description
Technical field
The utility model belongs to metallurgical technology field more particularly to a kind of prevents blast furnace copper cooling stave inlet and outlet pipes leak
Device.
Background technique
The furnace shell of blast furnace generallys use hot rolled steel plate and manufactures, and refractory lining is equipped in shell, in furnace shell and fire resisting
Cooling wall is installed between material liner, and is passed through cooling water and cooling wall is cooled down, with protect last furnace shell intensity and
Rigidity, especially in the furnace bosh of blast furnace, bosh position, due to extreme temperatures locating in production process, in order to guarantee cooling
Intensity, the cooling wall at these positions generally use oxygenless copper material production.But due to the physical characteristic of oxygenless copper material itself with
And weaker mechanical strength, in use, there is drainage often in inlet and outlet pipes and cooling wall junction, to jeopardize
The normal operation of blast furnace brings serious influence to production.
Utility model content
To solve the above problems, the utility model proposes one kind to prevent blast furnace copper cooling stave inlet and outlet pipes leak
Device, the apparatus structure is simple, reliability and durability, can effectively prevent cooling water and penetrate into furnace body filler, ensure blast furnace just
Often operating, promotes safety in production.
To achieve the goals above, the utility model uses following scheme, comprising:
The inlet and outlet pipes that copper cooling wall is embedded in after furnace shell, furnace body filler are sequentially passed through, the outer peripheral surface of the inlet and outlet pipes is along week
To on the outer peripheral surface for being continuously welded on copper cooling wall；
The inlet and outlet pipes are set with protective case, and the left end of the protective case extends radially outwardly to form the lug boss of annular, should
Lug boss is uniformly arranged in the circumferential direction several through-holes, and bolt passes through the through-hole rear thread on lug boss and connects copper cooling wall, lug boss
Its outer is welded on continuously in a circumferential on the outer peripheral surface of copper cooling wall；
Stuffed heat insulated filler between the inlet and outlet pipes and protective case；
The inlet and outlet pipes are set with retaining ring, which compresses thermal insulating filling；
The inlet and outlet pipes are set with seal closure, the left outer peripheral surface along sealed connection furnace shell of the seal closure, the right side of seal closure
Along the outer peripheral surface for being tightly connected inlet and outlet pipes, the lower part of seal closure is equipped with leakage inspection hole, and screw is removably threadedly coupled leakage
Water inspection hole.
The protective case is made of metal material.
The utility model structure is simple, reliability and durability, can effectively prevent cooling water and penetrate into furnace body filler, ensure blast furnace
Normal operation, promote safety in production.
Detailed description of the invention
Fig. 1 is the utility model section view schematic view of the front view.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, so that those skilled in the art can be more
Add and be apparent from, as shown in Figure 1, the utility model includes:
Sequentially pass through the inlet and outlet pipes 4 that copper cooling wall 3 is embedded in after furnace shell 1, furnace body filler 2, the outer peripheral surface of the inlet and outlet pipes
It is welded on the outer peripheral surface of copper cooling wall continuously in a circumferential；
The inlet and outlet pipes 4 are set with protective case 5, and the left end of the protective case extends radially outwardly to form the lug boss 6 of annular,
The lug boss is uniformly arranged in the circumferential direction several through-holes, and bolt 7 passes through the through-hole rear thread on lug boss and connects copper cooling wall 3, convex
Its outer of portion 6 is played to be welded on continuously in a circumferential on the outer peripheral surface of copper cooling wall；
Stuffed heat insulated filler 8 between the inlet and outlet pipes 4 and protective case 5；
The inlet and outlet pipes 4 are set with retaining ring 9, which compresses thermal insulating filling；
The inlet and outlet pipes 4 are set with seal closure 10, the left outer peripheral surface along sealed connection furnace shell 1 of the seal closure, seal closure
It is right along the outer peripheral surface for being tightly connected inlet and outlet pipes, the lower part of seal closure is equipped with leakage inspection hole, the dismountable screw thread of screw 11
Connect leakage inspection hole.
The protective case 5 is made of metal material.
The utility model structure is simple, reliability and durability, can effectively prevent cooling water and penetrate into furnace body filler, ensure blast furnace
Normal operation, promote safety in production.
The utility model is not limited to above-mentioned specific embodiment, as long as being set with protective case in inlet and outlet pipes, and will protect
Sheath is connected on the peripheral wall of copper cooling wall, no matter which kind of shape protective case uses, it is claimed to all fall within the utility model
Within the scope of.
