Description

Technical Field

[0001] This utility model relates to the field of flue gas pipe water blocking technology, specifically to a converter flue gas pipe water blocking structure. Background Technology

[0002] A converter generally refers to a tiltable cylindrical oxygen-blown steelmaking or copper-smelting vessel. The furnace body is cylindrical and mounted on a horizontal shaft, allowing it to rotate. Converter flue tubes (cylindrical hollow tubes) are used to exhaust the flue gas generated during the smelting process. The converter flue tubes run from outside the converter plant into the plant and through the roof. There is a gap between the flue tubes and the roof. When it rains, rainwater flows into the area around the furnace through the gap between the roof and the flue tubes, creating a significant hazard. The exhaust pipes (cylindrical hollow tubes) of the converter waste heat boiler run out of the roof from the steam drum. Similarly, there is a gap between the exhaust pipes and the roof. When it rains, rainwater flows into the steam drum through the pipes. Long-term rainwater inflow causes corrosion of the steam drum. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] In one embodiment, see Figure 1 , 2 The present invention relates to a converter flue pipe three-water-blocking structure, comprising an upper water-blocking component and a lower water-blocking component.

[0027] The upper water-blocking assembly includes an upper fixing member 1 and an upper water-blocking member 2 mounted on the upper fixing member 1. The upper fixing member 1 is divided into two groups and is detachably connected to the converter flue pipe 3. A first sealing member 4 is provided between the upper fixing member 1 and the converter flue pipe 3. The upper water-blocking member 2 is provided with an upper water guide groove 5 and an upper drain outlet 6 communicating with the upper water guide groove 5. The lower water-blocking assembly includes a lower fixing member 7 and a lower water-blocking member 8 mounted on the lower fixing member 7. The lower fixing member 7 is divided into two groups and is detachably connected to the converter flue pipe 3. The lower fixing member 7 is located below the upper fixing member 1. A second sealing member 9 is provided between the lower fixing member 7 and the converter flue pipe 3. A sealing member 10 with an increasing outer diameter is provided on the lower fixing member 7. The lower water-blocking member 8 is provided with a lower water guide groove 11 and a lower drain pipe 12 communicating with the lower water guide groove 11.

[0028] Further, see Figure 2 , 3 4. The upper fixing member 1 includes an upper fixing hoop 101 and an upper fixing ear plate 102 disposed on the upper fixing hoop 101. The bottom end of the upper fixing hoop 101 is provided with an upper connecting ring 103.

[0029] Preferably, the upper fixing hoop 101 is formed by dividing a circular ring into two parts. The upper fixing hoop 101 is supported by steel. The upper fixing ear plate 102 is welded to the upper fixing hoop 101. The upper fixing ear plate 102 is provided with a first connecting hole 104. The two sets of upper fixing hoops 101 are connected by bolts passing through the first connecting hole 104, thereby tightening the two sets of upper fixing hoops 101 on the outer wall of the converter flue 3.

[0030] Further, see Figure 3 , 4 The upper water baffle 2 includes an upper water baffle plate 201 disposed on the upper fixed hoop 101. The upper water baffle plate 201 is connected to the upper connecting ring 103. There is a gap between the edge of the upper water baffle plate 201 and the upper fixed hoop 101 to form an upper water guide groove 5.

[0031] Preferably, the upper baffle plate 201 is a hollow cylindrical structure with one end open. The closed end of the upper baffle plate 201 is provided with a first through hole 202 for the converter flue pipe 3 to pass through. The closed end of the upper baffle plate 201 is provided with a first connecting groove 203 so that the upper connecting ring 103 can be inserted, thereby connecting the upper baffle plate 201 and the upper connecting ring 103.

[0032] Preferably, the upper water baffle 201 is made of rubber, and the closed end of the upper water baffle 201 is provided with an upper wrapping sleeve 204, which is connected to the outer wall of the upper fixing hoop 101.

[0033] Further, see Figure 3 , 4The first sealing element 4 includes a first sealing sleeve 401 disposed on the inner wall of the upper fixing hoop 101, and there is a gap between the end of the first sealing sleeve 401 and the end of the upper fixing hoop 101.

[0034] Preferably, the first sealing sleeve 401 is made of elastic rubber. The top end of the first sealing sleeve 401 is connected to the closed end of the upper water baffle 201 and the upper wrapping sleeve 204 respectively, thereby wrapping the upper fixing hoop 101 and the upper connecting ring 103 inside.

[0035] Preferably, the shape of the first sealing sleeve 401 is consistent with the shape of the upper fixing band 101, and the end of the first sealing sleeve 401 extends beyond the end of the upper fixing band 101. After the two sets of upper fixing bands 101 are connected by the upper fixing ear plate 102, the two sets of first sealing sleeves 401 are joined together to form a ring shape. The joint of the two sets of first sealing sleeves 401 is staggered from the joint of the two sets of upper fixing bands 101, thereby preventing rainwater from entering from the joint.

[0036] In the above configuration, the converter flue pipe 3 passes through the roof. The upper fixing hoop 101 is installed outside the roof, and two sets of upper fixing hoops 101 encircle the outer wall of the converter flue pipe 3. The bottom end of the upper baffle plate 201 abuts against the roof. The two sets of upper fixing hoops 101 are connected and tightened by bolts passing through the first connecting hole 104, thereby connecting the upper fixing hoop 101 to the converter flue pipe 3. During the installation process, it is necessary to ensure that the upper drain outlet 6 faces the drainage direction of the roof. After the upper fixing hoop 101 is connected to the converter flue pipe 3, the first sealing sleeve 401 fits tightly with the converter flue pipe 3, thereby preventing rainwater from flowing down the converter flue pipe 3. After the external rainwater flows down the converter flue pipe 3, it is blocked by the first sealing sleeve 401 and enters the upper water guide trough 5, and flows out along the upper drain outlet 6 and is discharged along the roof.

[0037] Further, see Figure 2 , 5 6. The lower fixing member 7 includes a lower fixing hoop 701 and a lower fixing ear plate 702 disposed on the lower fixing hoop 701. The lower fixing hoop 701 is provided with a lower connecting ring 703.

[0038] Preferably, the lower fixing hoop 701 is formed by dividing a circular ring into two parts. The lower fixing hoop 701 is supported by steel. The lower fixing ear plate 702 is welded to the lower fixing hoop 701. The lower fixing ear plate 702 is provided with a second connecting hole 704. The two sets of lower fixing hoops 701 are connected by bolts passing through the second connecting hole 704, thereby tightening the two sets of lower fixing hoops 701 on the outer wall of the converter flue 3. The connection position of the lower fixing hoop 701 is located below the roof.

[0039] Further, see Figure 5 , 6The lower water baffle 8 includes a lower water baffle plate 801 disposed on the lower fixing hoop 701. The lower water baffle plate 801 is connected to the lower connecting ring 703. There is a gap between the edge of the lower water baffle plate 801 and the lower fixing hoop 701 to form a lower water guide groove 11.

[0040] Preferably, the lower baffle plate 801 is a hollow cylindrical structure with one open end. The closed end of the lower baffle plate 801 is provided with a second through hole 802 for the converter flue pipe 3 to pass through. The closed end of the lower baffle plate 801 is provided with a second connecting groove 803 so that the lower connecting ring 703 can be inserted, thereby connecting the lower baffle plate 801 and the lower connecting ring 703.

[0041] Preferably, the lower baffle plate 801 is made of rubber, and the closed end of the lower baffle plate 801 is provided with a lower wrapping sleeve 804, which is connected to the outer wall of the lower fixing hoop 701.

[0042] Further, see Figure 5 , 6 The second sealing element 9 includes a second sealing sleeve 901 disposed on the inner wall of the lower fixing hoop 701, and there is a gap between the end of the second sealing sleeve 901 and the end of the lower fixing hoop 701.

[0043] Preferably, the second sealing sleeve 901 is made of elastic rubber. The top end of the second sealing sleeve 901 is connected to the closed end of the lower baffle plate 801 and the lower wrapping sleeve 804 respectively, thereby wrapping the lower fixing hoop 701 and the lower connecting ring 703 inside.

[0044] Preferably, the shape of the second sealing sleeve 901 is consistent with the shape of the lower fixing band 701, and the end of the second sealing sleeve 901 extends beyond the end of the lower fixing band 701. After the two sets of lower fixing bands 701 are connected by the lower fixing ear plate 702, the two sets of second sealing sleeves 901 are joined together to form a ring shape. The joint of the two sets of second sealing sleeves 901 is staggered from the joint of the two sets of lower fixing bands 701, thereby preventing rainwater from entering from the joint.

[0045] Further, see Figure 6 The lower connecting ring 703 is provided with a lower support ring 13, which is located in the inner wall of the lower baffle plate 801. The ends of the lower connecting ring 703 and the lower support ring 13 are respectively provided with interlocking grooves 14 and plugs 15, and the plugs 15 are provided with a third sealing sleeve 16.

[0046] Preferably, the lower fixing hoop 701 is arranged parallel to the lower support ring 13.

[0047] Preferably, the outer wall thickness of the third sealing sleeve 16 increases.

[0048] In the above setup, the lower fixing clamp 701 is installed on the converter flue pipe 3 below the roof. During installation, the lower baffle plate 801 is located above the lower fixing clamp 701 and close to the roof. The plug 15 is inserted into the plug groove 14, and the two sets of lower fixing ear plates 702 are locked by bolts through the second connecting hole 704, thereby connecting the two sets of lower fixing clamps 701. The second sealing sleeve 901 fits tightly with the converter flue pipe 3. The joint of the second sealing sleeve 901 is staggered from the joint of the lower fixing clamp 701 to improve sealing. The plug 15 is inserted into the plug groove 14 and connected to the plug groove 14 through the third sealing sleeve, thereby sealing the connection of the lower connecting ring 703 and the lower support ring 13 on the two sets of lower fixing clamps 701. Rainwater flowing from the roof along the gap between the converter flue pipe 3 and the roof enters the lower water guide trough 11 and is discharged outside the factory through the lower drain pipe 12 to prevent rainwater from falling.

[0049] It should be noted that when the converter flue pipe 3 passes through the roof, a hole needs to be opened in the roof. The inner diameter of the upper baffle plate 201 and the lower baffle plate 801 is larger than the inner diameter of the hole. The upper baffle plate 201 can cover the hole, and the lower baffle plate 801 can receive the rainwater flowing from the roof.

[0050] Further, see Figure 6 The sealing component 10 includes a sealing ring 1001 connected to the lower fixing hoop 701 and a sealing sleeve 1002 disposed on the sealing ring, with the outer diameter of the sealing sleeve 1002 increasing progressively.

[0051] Preferably, the sealing ring 1001 and the lower fixing hoop 701 are integrally formed, and the height of the sealing ring 1001 is greater than the height of the lower baffle plate 801.

[0052] When connecting the lower fixing hoop 701 to the converter flue pipe 3, the sealing sleeve 1002 is first moved upward along the converter flue pipe 3 and inserted into the gap between the converter flue pipe 3 and the roof. As the sealing sleeve 1002 moves upward, the gap decreases accordingly. After the lower fixing hoop 701 is connected to the converter flue pipe 3, the lower baffle plate 801 is located outside the sealing sleeve 1002. Rainwater flowing along the gap between the roof and the upper fixing hoop 101 reaches the sealing sleeve 1002. Some rainwater flows into the lower baffle plate 801 along the gap between the sealing sleeve and the roof that is not completely closed, and is discharged through the lower drain pipe 12. Some rainwater flows along both sides of the converter flue pipe 3 outside the roof, bypasses the converter flue pipe 3, and finally flows out along the roof.

[0053] In this embodiment, after the upper fixing hoop 101 is connected to the converter flue pipe 3, it covers the gap between the converter flue pipe 3 and the hole in the roof. The falling rainwater enters the upper water guide trough 5 and flows along the upper drain outlet 6 to the roof for discharge. When the rainwater falling on the roof flows down to the converter flue pipe 3, there is a gap between the roof and the upper fixing hoop 101 (there is a water trough between the roofs built with color steel tiles, etc., and the upper baffle plate 201 cannot close the water trough). At this time, the rainwater flows into the space between the upper baffle plate 201 and the roof and reaches the converter flue pipe 3. With the sealing of the sealing component 10, the gap between the converter flue pipe 3 and the roof becomes smaller, but there may still be a gap. Some rainwater flows into the lower baffle plate 801 along the gap, and some rainwater bypasses the converter flue pipe 3 and is discharged along the roof, thereby preventing rainwater from flowing into the plant.

[0054] The principle of exhaust pipes is the same. Both exhaust pipes that penetrate the roof and converter flue pipe 3 that penetrate the roof are pipes that penetrate the roof. The above-mentioned methods can be used to shield and divert rainwater to prevent rainwater from entering the factory.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
