Abstract
The utility model discloses a protecting pipe of the water inlet and outlet pipe, in particular to a protecting pipe of the water inlet and outlet pipe with the bronze cooling wall, belonging to the technical field of mechanical engineering. The protecting pipe comprises a water inlet and outlet pipe and a pup joint used for installing the bellows; wherein, the pup joint is welded on the water inlet and outlet pipe, which is welded on the body of the bronze cooling wall. A steel pipe is arranged outside the water inlet and outlet pipe and the pup joint. During installing the bronze cooling wall, the protecting pipe of the utility model provides conditions for separating the inside and outside of the blast furnace so as to prevent the refractory material from entering into the bellows during grouting of the blast furnace and enable the bellows arranged outside the furnace mantle to perform the effective displacement absorption function. The utility model can be widely used for installing the water inlet and outlet pipe on the bronze cooling wall.
Description
Technical field
The utility model belongs to mechanical engineering technical field, discloses a kind of protective tube of water inlet pipe and water outlet pipe, particularly the protective tube of copper cooling wall water inlet pipe and water outlet pipe.
Background technology
At present; the copper cooling wall that blast furnace uses, at the protection short tube that the water inlet pipe and water outlet pipe root is provided with, the one end is that direct spot welding is on wall body; its diameter is about DN150mm, and its length is standard with the other end that copper cooling wall installs back protection short tube apart from furnace shell inwall 10mm.This protection short tube is to reach outside the furnace shell.
When copper cooling wall was installed, the 10mm gap between furnace shell and the protection short tube was to adopt materials such as porous plastics backing plate or rubber cradle to fill.But these materials are easily in follow-up construction process, scaling loss occurs during because of the tightness system (as corrugated tube) of furnace shell external welding water inlet pipe and water outlet pipe, thereby make this gap the cavity occur.Because after installing copper cooling wall, also need between cooling stave and furnace shell, implement to press the filling refractory materials, therefore, these cavities can cause refractory materials directly to enter in the outer tightness system of installing (as corrugated tube) of furnace shell, thereby cause the water inlet pipe and water outlet pipe of copper cooling wall stiff in watertight chest, also make corrugated tube absorb the performance failure of displacement simultaneously.In case this situation occurs, the water inlet pipe and water outlet pipe that can directly cause copper cooling wall consequently makes the water inlet pipe and water outlet pipe of copper cooling wall and wall body weld stress fatigue occur, rupture because of the displacement that temperature fluctuation in the stove produces can not be absorbed by corrugated tube.This situation takes place on the indivedual blast furnaces of China, and jeopardizes the safety and the longevity of this blast furnace.
Summary of the invention
At above-mentioned condition, the purpose of this utility model provides a kind of protective tube of copper cooling wall water inlet pipe and water outlet pipe, to eliminate the generation of above-mentioned situation.The utility model can be widely used in installing of copper cooling wall water inlet pipe and water outlet pipe.
The technical scheme that realizes above-mentioned purpose is: the utility model is made up of the short tube of water inlet pipe and water outlet pipe and installation corrugated tube; the short tube that corrugated tube is installed is welded on the water inlet pipe and water outlet pipe; water inlet pipe and water outlet pipe is welded on the wall body of copper cooling wall, outside the short tube of water inlet pipe and water outlet pipe and installation corrugated tube the protection steel pipe is set.Between protective tube and copper cooling wall wall body, adopt continuous welding.
Beneficial effect of the present invention is embodied in:
The protection steel pipe of being installed stretches out outside the furnace shell with the water inlet pipe and water outlet pipe of copper cooling wall together; before being installed into the tightness system of rising pipe; can outside furnace shell, adopt a metal o-ring that the perforate of furnace shell is sealed fully, the inner ring of sealing circle and the welding of protection steel pipe, outer ring and furnace shell welding.Again be installed into the tightness system of rising pipe thereafter.When having guaranteed that so follow-up pressure is irritated refractory materials, can not filled in the watertight chest, so that the outer corrugated tube of installing of furnace shell can play the effect of effective absorption displacement by refractory materials.
Description of drawings
Accompanying drawing 1 is the structure sectional view of embodiment one;
Accompanying drawing 1 is the structure sectional view of embodiment two;
In the accompanying drawing: part 1 is a water inlet pipe and water outlet pipe, and part 2 is for installing the short tube of corrugated tube, and part 3 is a protective tube, and part 4 is a metal ring, and part 5 is a short tube, and part 6 is a copper cooling wall.
Embodiment
1,2 couples of the present invention specify below in conjunction with accompanying drawing:
A kind of protective tube of copper cooling wall water inlet pipe and water outlet pipe; short tube 2 by water inlet pipe and water outlet pipe 1 and installation corrugated tube is formed; the short tube 2 that corrugated tube is installed is welded on the water inlet pipe and water outlet pipe 1, and water inlet pipe and water outlet pipe 1 is welded on the wall body of copper cooling wall 6, outside the short tube 2 of water inlet pipe and water outlet pipe 1 and installation corrugated tube protection steel pipe 3 is set.
Among the embodiment as shown in Figure 1; be welded on the short tube 2 that corrugated tube is installed at set protection steel pipe 3 one ends; metal ring 4 of the other end welding, the end welding of the outer ring of metal ring 4 and short tube 5, the other end of short tube 5 directly is welded on the wall body of copper cooling wall 6.Adopt continuous welding between protection short tube 5 and copper cooling wall 6 wall bodies.
Among the embodiment as shown in Figure 2, set protection steel pipe 3 one ends directly are welded on the wall body of copper cooling wall 6 through enlarging, and the other end of protection steel pipe 3 is welded on the short tube 2 that corrugated tube is installed.Adopt continuous welding between protection steel pipe 3 and copper cooling wall 6 wall bodies.
Water inlet pipe and water outlet pipe 1 can be a straight tube, can an end be the band flared also.
Protective tube of the present utility model is when copper cooling wall is installed; the inside and outside isolated condition that provides of blast furnace of implementing is provided; thereby prevent that the situation that refractory materials that blast furnace grouting may cause enters corrugated tube from occurring, so that the outer corrugated tube of installing of furnace shell can play the effect of effective absorption displacement.Can be widely used in installing of copper cooling wall water inlet pipe and water outlet pipe.
