Description

Technical Field

[0001] The utility model relates to the technical field of pipeline auxiliary devices, in particular to a novel compensator for blast furnace air supply. Background Art

[0002] A bellows compensator is a compensating element that utilizes the effective expansion and contraction of the bellows as its working body to absorb dimensional changes in pipelines, ducts, containers, etc. caused by thermal expansion and contraction, or to compensate for axial, lateral, and angular displacements of pipelines, ducts, containers, etc. Among them, the blast furnace air inlet device is a device that delivers hot air at nearly 1300°C in the hot blast pipe into the blast furnace through the tuyere sleeve. During the installation of the blast furnace air inlet device, a bellows compensator is required to absorb dimensional changes in the air inlet device caused by thermal expansion and contraction, blast furnace deformation, etc. Among them, due to the high operating temperature of the blast furnace air inlet device, the corrugated compensator used in the blast furnace air inlet device is installed with a lining made of refractory material. In order to avoid damage to the lining inside the compensator when the compensator is deformed, the lining is set to a split type. There is a movable gap between the two parts of the lining to provide a movable margin for the compensator when it is deformed, thereby avoiding damage to the lining made of refractory material.

[0003] However, the existing bellows compensators are generally installed on the compensation rods by using bolt threads, and the position of the bolts is rotated to achieve the expansion and contraction of the bellows compensator pipe. However, the bellows compensator is generally provided with multiple bolt compensation rods, which makes it necessary to rotate and tighten more bolts to adjust the length of the bellows compensator pipe, which is not only laborious but also makes the efficiency of adjusting the length of the bellows compensator pipe slow, thereby reducing the practicality of the bellows compensator.

However, generally, a plurality of bolt compensating rods are provided for the corrugated compensator, which makes it necessary to rotate and tighten more bolts to adjust the length of the corrugated compensator pipe, which is not only laborious but also makes the efficiency of adjusting the length of the corrugated compensator pipe slow, thereby reducing the practicality of the corrugated compensator.

[0022] (3) Beneficial effects

[0023] Compared with the prior art, the present invention provides a new compensator for blast furnace air supply, which has the following beneficial effects:

[0024] 1. The new compensator for blast furnace air supply realizes the expansion and contraction of the compensator pipe, and the adjustment is convenient and quick. It is more labor-saving and faster than the traditional adjustment using bolt compensation rods. Adjustment can be achieved by simply turning the positioning handle, which is more flexible to operate, thereby facilitating the installation and adjustment of the new compensator for blast furnace air supply, thereby increasing the practicality and flexibility of the new compensator for blast furnace air supply.

[0025] 2. In the new compensator for blast furnace air supply, the rotating block and the rotating groove serve to connect the threaded rod and the second support block, so that the threaded rod can only rotate on the second support block and will not be separated from the second support block, thereby ensuring the expansion and contraction of the compensator pipe when the threaded rod rotates, thereby ensuring the practicality of the new compensator for blast furnace air supply.

[0026] 3. The new compensator for blast furnace air supply has two sliding rings that connect and support the connecting gear ring and the fixed gear. Because the four fixed gears are slidingly connected between the two sliding rings, the two sliding rings can prevent the connecting gear ring from falling due to gravity, thereby ensuring the normal engagement of the four fixed gears with the connecting gear ring, thereby ensuring the practicality of the new compensator for blast furnace air supply.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-4 , the utility model provides a new technical solution: a new compensator for blast furnace air supply, comprising two compensator connecting pipes 1, a bellows 3 and two fixing flanges 2;

[0034] Among them, the compensator connecting pipe 1, the bellows 3 and the two fixing flanges 2 are the existing structures of the existing bellows compensator, which are existing technologies and will not be described in detail here;

[0035] The bellows 3 is fixedly connected between the two compensator connecting pipes 1, and the two fixing flanges 2 are fixedly sleeved on the two opposite ends of the two compensator connecting pipes 1;

[0036] Among them, four second support blocks 5 are fixedly connected to the outer surface of the lower fixed flange 2;

[0037] Among them, the four second support blocks 5 are arranged in a central array;

[0038] Among them, a positioning mechanism is provided on the four second support blocks 5, and the positioning mechanism includes a first support block 4, a fixed gear 6, a threaded rod 7, a connecting gear ring 8, a sliding ring 9, a positioning handle 10, a rotating block 11 and a rotating groove 12.

[0039] Furthermore, four rotation slots 12 are provided in the four second support blocks 5;

[0040] Among them, the four rotating blocks 11 are slidably sleeved in the four rotating grooves 12;

[0041] The four threaded rods 7 are rotatably connected to the upper surfaces of the four second support blocks 5 , and the lower ends of the four threaded rods 7 are rotatably inserted into the four rotation grooves 12 and fixedly connected to the outer surfaces of the four rotation blocks 11 .

[0042] Furthermore, four first support blocks 4 are fixedly connected to the outer surface of the fixing flange 2 located on the upper side;

[0043] Among them, the four first support blocks 4 are threadedly sleeved on the outer surfaces of the four threaded rods 7;

[0044] The four first support blocks 4 are also arranged in a central array.

[0045] Furthermore, four fixed gears 6 are fixedly connected to the upper ends of four threaded rods 7;

[0046] Among them, the connecting gear ring 8 is meshed and connected with the four fixed gears 6;

[0047] The two sliding rings 9 are fixedly connected to the upper and lower outer surfaces of the connecting gear ring 8 .

[0048] Furthermore, the four fixed gears 6 are slidably connected between the two sliding rings 9;

[0049] The two positioning handles 10 are fixedly connected to the upper surface of the sliding ring 9 located on the upper side.

[0050] Furthermore, when in use, rotating the positioning handle 10 can drive the two sliding rings 9 and the connecting gear ring 8 to rotate. In this process, the connecting gear ring 8 drives the four fixed gears 6 to rotate, and then synchronously drives the threaded rod 7 to rotate. During the rotation of the threaded rod 7, the first support block 4 is driven to move up and down, and then the upper fixed flange 2 is synchronously driven to move up and down. In this process, the bellows 3 is stretched or compressed, thereby realizing the expansion and contraction of the compensator pipe. The adjustment is convenient and fast, which is more labor-saving and faster than the traditional adjustment using bolt compensation rods. The adjustment can be achieved by simply rotating the positioning handle 10, and the operation is more flexible, thereby facilitating the installation and adjustment of the new compensator for blast furnace air supply, thereby increasing the practicality and flexibility of the new compensator for blast furnace air supply.

[0051] Furthermore, in this solution, the rotating block 11 and the rotating groove 12 serve to connect the threaded rod 7 and the second support block 5, so that the threaded rod 7 can only rotate on the second support block 5 and will not be separated from the second support block 5, thereby ensuring the expansion and contraction of the compensator pipe when the threaded rod 7 rotates, thereby ensuring the practicality of the new compensator used for blast furnace air supply.

[0052] Furthermore, when in use, the two sliding rings 9 connect and support the connecting gear ring 8 and the fixed gear 6. Since the four fixed gears 6 are slidingly connected between the two sliding rings 9, the two sliding rings 9 can prevent the connecting gear ring 8 from falling due to gravity, thereby ensuring the normal engagement of the four fixed gears 6 with the connecting gear ring 8, thereby ensuring the practicality of the new compensator used for blast furnace air supply.

[0053] Working principle: When the device is used, the two sliding rings 9 and the connecting gear ring 8 can be driven to rotate by rotating the positioning handle 10. In this process, the connecting gear ring 8 drives the four fixed gears 6 to rotate, and then synchronously drives the threaded rod 7 to rotate. During the rotation of the threaded rod 7, it drives the first support block 4 to move up and down, and then synchronously drives the upper fixed flange 2 to move up and down. In this process, the bellows 3 is stretched or compressed, thereby realizing the expansion and contraction of the compensator pipe. The adjustment is convenient and fast, which is more labor-saving and faster than the traditional adjustment using bolt compensation rods. It only needs to rotate the positioning handle 10 to achieve adjustment, and the operation is more flexible, which facilitates the installation and adjustment of the new compensator used for blast furnace air supply, thereby increasing the practicality and flexibility of the new compensator used for blast furnace air supply.
