Description

Technical Field

[0001] The invention relates to the technical field of furnace tube clamps, in particular to a device for improving blowout damage of furnace tube clamps. Background Art

[0002] Furnace tube clamps are important components used to fix and support furnace tubes in industrial furnace systems. Their design, material, and performance directly affect the stability and safety of the furnace tubes, as well as the thermal efficiency and maintenance costs of the entire furnace system.

[0003] The existing boiler tubes are installed in the flue at the rear of the boiler. The tubes need to be fixed by a fixing mechanism to stabilize them on the inner wall of the flue. The fixing mechanism is a semicircular tube clamp. When the existing tubes are used in the flue for a long time, a lot of smoke and dust will adhere to their surface. In order to avoid the heating effect of the tubes, the tube surfaces often need to be cleaned. Currently, the tubes are cleaned by air blowing. During the gas blowing cleaning process, the tube clamp cannot fit completely with the tubes, so the gas will blow the smoke and dust into the gap between the tubes and the clamp, resulting in vortices in the gap, which can easily aggravate the wear of the tubes and make it difficult to seal the gap between the clamp and the tubes during air blowing cleaning. To this end, a new technical solution needs to be designed to solve this problem. Summary of the Invention

[0004] The object of the present invention is to provide a device for improving the blow-out damage of furnace tube clamps, which solves the problem in the background art that it is inconvenient to seal the gap between the tube clamp and the furnace tube during air blowing cleaning.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for improving the blow-out damage of a furnace tube clamp, comprising a tube clamp body, an inner cavity of the tube clamp body being provided with an elastic bonding plate, an inner wall of the elastic bonding plate being fixedly connected to a thermal expansion arc pad;

[0006] It also includes a push rod, and there are multiple push rods. All of the push rods are movable through the outer wall of the tube clamp body. The inner end of the push rod is connected to the elastic bonding plate. The outer wall of the push rod is equipped with a spring, and the two ends of the spring are respectively fixedly connected to the inner wall of the tube clamp body and the outer wall of the elastic bonding plate.

[0007] By adopting the above technical solution, the two pipe clamp bodies are sleeved on the outer wall of the furnace tube, and then fastened with bolts, and the entire device is installed and fixed with a hanger, so as to fix the furnace tube. In actual use, the spring forms a thrust on the elastic bonding plate, thereby driving the elastic bonding plate and the thermal expansion arc pad to fit the outer wall of the furnace tube, which is beneficial to improve the fit. When the furnace tube needs to be cleaned, gas is blown to the surface of the furnace tube, and the fit is high, which is beneficial to reduce the intrusion of smoke and dust into the gap between the furnace tube and the thermal expansion arc pad, thereby helping to reduce the wear of the furnace tube caused by smoke and dust entering. At the same time, the gas will impact the inclined plate, so that the inclined plate will form a certain thrust on the push rod stroke, thereby forming a thrust on the elastic bonding plate, which is beneficial to further improve the fit between the elastic bonding plate and the thermal expansion arc pad and the furnace tube, thereby helping to further improve the anti-smoke and dust intrusion effect.

[0008] As a preferred embodiment of the present invention, a through hole is provided on the surface of the inclined plate, the push rod is a hollow structure, the tail end of the push rod passes through the elastic bonding plate and is connected to the air distribution plate installed in the middle of the top of the thermal expansion arc pad, the air distribution plate is a hollow structure, airbag strips are fixed on both sides of the top of the thermal expansion arc pad, the air distribution plate is connected to the two airbag strips through multiple conduits, and a mesh cover is rotatably connected to the through hole on the surface of the inclined plate.

[0009] By adopting the above technical solution, when the gas acts on the inclined plate, it can pass through the mesh cover, so that the gas enters the cavity of the push rod, and then enters the gas distribution plate, and then enters the airbag strips in the inner cavity at both ends of the thermal expansion arc pad, so that the airbag strips can expand, thereby further improving the fit between the thermal expansion arc pad and the furnace tube, which is beneficial to further improve the situation of wear caused by smoke and dust intrusion.

[0010] As a preferred embodiment of the present invention, the tail end of the push rod is fixedly connected to a threaded tube, and a threaded hole is opened on the top of the air distribution plate corresponding to the push rod, and the threaded tube is engaged with the threaded hole.

[0011] By adopting the above technical solution, the threaded pipe and the air distribution plate are connected, which makes it easy to disassemble and thus facilitates the inspection and maintenance.

[0012] As a preferred embodiment of the present invention, a plurality of evenly distributed blades are fixedly connected to the outer wall of the mesh cover.

[0013] By adopting the above technical solution, the blades are set so that when the gas blows towards the surface of the mesh cover, it can blow towards the surface of the blades, thereby driving the mesh cover to rotate, so that the dust and impurities adhering to the surface of the mesh cover can be thrown off by centrifugal force, thereby achieving self-cleaning, which is beneficial to avoid dust adhesion affecting the entry of gas.

[0014] As a preferred embodiment of the present invention, the outer wall of the tube clamp body is provided with a plurality of evenly distributed strip grooves, the inner cavity of the strip groove is provided with a roller, the outer wall of the roller is fixed with a plurality of evenly distributed fixing plates, both ends of the roller are connected to a retaining frame, and the retaining frame is fixed to the inner wall of the strip groove.

[0015] By adopting the above technical solution, in actual use, first, when the gas impacts the surface of the tube clamp body, it can enter the strip groove and then impact the fixed plate on the outer wall of the roller, so that the roller can rotate, thereby redirecting the gas directly impacting the outer wall of the tube clamp body, thereby helping to reduce the damage to the tube clamp body caused by direct impact of the gas and protecting the tube clamp body.

[0016] As a preferred embodiment of the present invention, both side walls of the pipe clamp body are provided with arc-shaped chamfers.

[0017] By adopting the above technical solution, the setting of the arc chamfer can make the gas flow more smoothly at the corners of the tube clamp body when the gas passes through the tube clamp body, which is beneficial to further reduce damage to the tube clamp body.

[0018] As a preferred embodiment of the present invention, connecting plates are fixed to both ends of the pipe clamp body, and connecting holes are opened on both sides of the surface of the connecting plates.

[0019] By adopting the above technical solution, the arrangement of the connecting plate and the connecting hole makes it convenient to dock the pipe clamp body and to connect it to the hanger.

[0020] As a preferred embodiment of the present invention, the thermal expansion arc pad is a silicone rubber pad.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The present invention provides an elastic fitting plate on the inner wall of the pipe clamp body. The elastic fitting plate is pushed by multiple springs to improve the fit between the elastic fitting plate and the outer wall of the furnace tube. The thermal expansion arc pad on the inner wall of the elastic fitting plate can expand when heated, thereby further improving the fit when heated. This helps to prevent dust and impurities from invading the gap between the pipe clamp and the furnace tube during purging, causing wear of the furnace tube.

[0023] During the purge, the gas will impact the inclined plate, which will generate a certain thrust on the push rod stroke, thereby generating a thrust on the elastic bonding plate, which is conducive to further improving the fit between the elastic bonding plate and the thermal expansion arc pad and the furnace tube, thereby further improving the anti-smoke and dust intrusion effect;

[0024] When the gas acts on the inclined plate, it can pass through the mesh cover, so that the gas enters the cavity of the push rod, and then enters the gas distribution plate, and then enters the airbag strips in the inner cavity at both ends of the thermal expansion arc pad, so that the airbag strips can expand, thereby further improving the fit between the thermal expansion arc pad and the furnace tube, which is beneficial to further improve the situation of wear caused by smoke and dust intrusion.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. A person of ordinary skill in the art will understand the specific meanings of the above terms in the present invention in specific circumstances. The models of electrical appliances provided in the present invention are for reference only, and different models of electrical appliances with the same functions can be replaced according to actual usage.

[0039] See also Figure 1-5 The present invention provides a technical solution: a device for improving the blow-out damage of a furnace tube clamp, comprising a tube clamp body 1, an inner cavity of the tube clamp body 1 is provided with an elastic bonding plate 12, and an inner wall of the elastic bonding plate 12 is fixedly connected with a thermal expansion arc pad 2;

[0040] It also includes a push rod 14, and there are multiple push rods 14. The multiple push rods 14 are movable through the outer wall of the tube clamp body 1. The inner end of the push rod 14 is connected to the elastic bonding plate 12. The outer wall of the push rod 14 is covered with a spring 15. The two ends of the spring 15 are fixedly connected to the inner wall of the tube clamp body 1 and the outer wall of the elastic bonding plate 12 respectively.

[0041] It should be understood that in actual use, the two pipe clamp bodies 1 are put on the outer wall of the furnace tube, and then fastened with bolts, and the entire device is installed and fixed with a hanger to achieve the fixation of the furnace tube. In actual use, the spring 15 forms a thrust on the elastic bonding plate 12, thereby driving the elastic bonding plate 12 and the thermal expansion arc pad 2 to fit the outer wall of the furnace tube, which is beneficial to improve the fit. When the furnace tube needs to be cleaned, gas is blown to the surface of the furnace tube, and the fit is high, which is beneficial to reduce the intrusion of smoke and dust into the gap between the furnace tube and the thermal expansion arc pad, and thus helps to reduce the wear of the furnace tube caused by smoke and dust entering. At the same time, the gas will impact on the inclined plate 13, so that the inclined plate 13 will form a certain thrust on the stroke of the push rod 14, thereby forming a thrust on the elastic bonding plate 12, which is beneficial to further improve the fit between the elastic bonding plate 12 and the thermal expansion arc pad 2 and the furnace tube, and thus helps to further improve the anti-smoke and dust intrusion effect.

[0042] Furthermore, connecting plates 11 are fixed at both ends of the pipe clamp body 1, and connecting holes 16 are opened on both sides of the surface of the connecting plate 11. The setting of the connecting plate 11 and the connecting holes 16 makes it convenient to dock the pipe clamp body 1 and connect it to the hanger.

[0043] Furthermore, the thermal expansion arc pad is a silicone rubber pad. The setting of the silicone rubber pad has high temperature resistance and thermal expansion performance, thereby ensuring the fit under high temperature conditions.

[0044] like Figure 1 and 2 , 4, 5; the inclined plate 13 is provided with a through hole on its surface, the push rod 14 is a hollow structure, the tail end of the push rod 14 passes through the elastic fitting plate 12 and is connected to the air distribution plate 22 installed in the middle of the top of the thermal expansion arc pad 2, the air distribution plate 22 is a hollow structure, and airbag strips 21 are fixed on both sides of the top of the thermal expansion arc pad 2. The air distribution plate 22 is connected to the two airbag strips 21 through a plurality of conduits 23, and the mesh cover 3 is rotatably connected to the through hole on the surface of the inclined plate 13;

[0045] It should be understood that in actual use, when the gas acts on the inclined plate 13, it can pass through the mesh cover 3, so that the gas enters the cavity of the push rod 14, and then enters the gas distribution plate 22, and then enters the airbag strip 21 in the inner cavity at both ends of the thermal expansion arc pad 2, so that the airbag strip 21 can expand, thereby further improving the fit between the thermal expansion arc pad 2 and the furnace tube, which is beneficial to once again improve the situation of preventing smoke and dust intrusion and causing wear.

[0046] Furthermore, the tail end of the push rod 14 is fixedly connected to a threaded tube 18 , and a threaded hole is provided on the top of the air distribution plate 22 corresponding to the push rod 14 , and the threaded tube 18 is engaged with the threaded hole.

[0047] It should be understood that the threaded pipe 18 and the gas distribution plate 22 are connected so as to facilitate disassembly, thereby facilitating inspection and maintenance.

[0048] Furthermore, a plurality of evenly distributed blades 31 are fixedly connected to the outer wall of the mesh cover 3 .

[0049] It should be understood that the arrangement of the blades 31 enables the gas to blow toward the surface of the mesh cover 3 when blowing toward the surface, thereby driving the mesh cover 3 to rotate, so that the dust and impurities adhering to the surface of the mesh cover 3 can be thrown off by centrifugal force, thereby achieving self-cleaning, which is beneficial to avoid dust adhesion affecting the entry of gas.

[0050] like Figure 2 and 3As shown; the outer wall of the pipe clamp body 1 is provided with a plurality of evenly distributed strip grooves 17, the inner cavity of the strip groove 17 is provided with a roller 4, the outer wall of the roller 4 is fixed with a plurality of evenly distributed fixing plates 41, and both ends of the roller 4 are connected to a retaining frame 42, which is fixed to the inner wall of the strip groove 17.

[0051] It should be understood that in actual use, the gas first impacts the surface of the tube clamp body 1 and can enter the strip groove 17, thereby impacting the fixed piece 41 on the outer wall of the roller 4, so that the roller 4 can rotate, thereby redirecting the gas directly impacting the outer wall of the tube clamp body 1, thereby helping to reduce the damage to the tube clamp body 1 caused by direct impact of the gas, and helping to protect the tube clamp body 1.

[0052] like Figure 1 As shown, both side walls of the tube clamp body 1 are provided with arc chamfers. The arc chamfers can make the gas flow more smoothly at the corners of the tube clamp body 1 when the gas passes through the tube clamp body 1, thereby further reducing damage to the tube clamp body 1.
