Description

Technical Field

[0001] This utility model relates to the field of baffle door technology, specifically an ultra-high temperature adjustable baffle door. Background Technology

[0002] A baffle-type regulating gate is a mechanical device that controls the flow rate, pressure, or direction of fluids (gas, liquid, etc.) through a movable baffle (or blade) structure. It is widely used in ventilation, pipelines, industrial equipment, and other fields. Baffle-type regulating gates are widely used in flue gas ducts to regulate flow rate, and can also cut off the flow of media in flue gas ducts.

[0003] Currently, high-temperature pipelines, such as those in northern heating systems, can reach temperatures exceeding 1000℃. Ordinary regulating valves cannot achieve true high-temperature resistance, affecting their service life. Therefore, we have proposed an ultra-high temperature adjustable baffle valve to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an ultra-high temperature adjustable baffle gate, which solves the problem that ordinary adjustable gates cannot achieve true high temperature resistance and thus affect service life in high-temperature pipelines, such as those in northern heating systems where temperatures can reach over 1000℃.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an ultra-high temperature adjustable baffle door, including a frame, the inner cavity of the frame is provided with blades, the inner cavity of each blade is provided with a shaft, the shaft passes through both sides of the frame, and the outer wall of the frame is provided with seated bearings for supporting the shafts; The axles are connected by a linkage assembly on the same side. A scale is provided on the outer wall of the frame below the linkage assembly. The other end of one of the axles is connected to a door hinge, and a remote transmission assembly is connected to the door hinge.

[0006] Preferably, the frame is made of 310S material folded into a U-shape.

[0007] Preferably, a reinforcing rod is provided in the middle of the inner cavity of the frame.

[0008] Preferably, the blade is a hollow reinforced airfoil.

[0009] Preferably, elastic sealing sheets are fixed on both sides of the blade.

[0010] Preferably, the linkage assembly includes a rotating frame disposed at one end of each of the shafts, and two adjacent rotating frames are movably connected by a first transmission rod, wherein an indicator needle is disposed on the rotating frame located at the bottom end.

[0011] Preferably, the remote transmission assembly includes a base, on which an electric component is disposed, and the output end of the electric component is connected to a ball joint; One end of the ball joint is connected to a crank via a second transmission rod, and one end of the crank is connected to the door hinge.

[0012] Preferably, the electric component is a drive motor. Beneficial effects

[0013] This utility model provides an adjustable baffle door for ultra-high temperature applications. Compared with the prior art, it has the following advantages: This ultra-high temperature adjustable baffle gate uses multiple shafts to install corresponding blades, which can also be mounted on a frame at both ends via bearings. This allows the blades to rotate around the shafts. Since the multiple shafts are connected on the same side via a linkage assembly, and one shaft's other end is connected to a door hinge with a remote transmission assembly, the remote transmission assembly can drive one shaft to rotate via the door hinge. This rotation, through the linkage assembly, synchronously drives all the other shafts to rotate. This rotation of the shafts and linkage assembly enables the opening and closing and adjustment of the blades. The blades can stop at different angles, and a scale, in conjunction with the linkage assembly, allows users to easily control the blade opening and closing angle, thus regulating the flow rate of the pipeline medium. Therefore, the baffle gate remains structurally stable and deformation-free in ultra-high temperature environments, is reliable, operates flexibly, and has a long service life, significantly reducing maintenance and replacement costs for users.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 The present invention provides a technical solution: an ultra-high temperature adjustable baffle door, including a frame 1, a blade 2 is provided in the inner cavity of the frame 1, and a shaft 3 is provided in the inner cavity of each blade 2. The shaft 3 passes through both sides of the frame 1, and a seated bearing 4 is provided on the outer wall of the frame 1 for supporting the shaft 3. The shafts 3 are connected by a connecting rod assembly 5 on the same side. A scale 13 is provided on the outer wall of the frame 1 and below the connecting rod assembly 5. The other end of one of the shafts 3 is connected to a door hinge 6, and a remote transmission assembly is connected to the door hinge 6. Multiple shafts 3 allow for the separate installation of corresponding blades 2, which can also be mounted on the frame 1 via bearings 4 at both ends. This enables the blades 2 to rotate around the shafts 3. Since the multiple shafts 3 are connected on the same side via a connecting rod assembly 5, and one end of one shaft 3 is connected to a door hinge 6, which is connected to a remote transmission assembly, the remote transmission assembly can drive one shaft 3 to rotate via the door hinge 6. This rotation is then transmitted through the connecting rod assembly 5, synchronously driving all the other shafts 3 to rotate. This allows the rotation of the shafts 3 and the connecting rod assembly 5 to open and close the blades 2, and the blades 2 can be stopped at different angles. The scale 13, in conjunction with the connecting rod assembly 5, allows users to easily control the opening and closing angle of the blades 2, thereby regulating the flow rate of the pipeline medium. Therefore, the baffle gate remains structurally stable and undeformed even in ultra-high temperature environments, is reliable in use, flexible in opening and closing, and has a long service life, greatly reducing the user's maintenance and replacement costs.

[0018] See Figure 1 The frame 1 is made of 310S material and folded into a U-shape, which can not only ensure the structural strength of the frame 1, but also improve its high temperature resistance and thus improve its service life.

[0019] See Figure 1 A reinforcing rod 7 is provided in the middle of the inner cavity of frame 1, which can strengthen the entire frame 1 structure.

[0020] See Figure 1 , Figure 3 Blade 2 is a hollow reinforced airfoil, and elastic sealing plates are fixed on both sides of blade 2, which can interact with each other to achieve good sealing performance when blade 2 is fully closed.

[0021] See Figure 1 , Figure 4 and Figure 5 The linkage assembly 5 includes a rotating frame 51 disposed at one end of each shaft 3, and two adjacent rotating frames 51 are movably connected by a first transmission rod 52, wherein an indicator needle 53 is disposed on the rotating frame 51 located at the bottom end; Each rotating frame 51 in the linkage assembly 5 can be installed at one end of each shaft 3, and two adjacent rotating frames 51 can be connected by multiple first transmission rods 52. Therefore, when one of the shafts 3 rotates, it can synchronously drive the other shaft 3 to rotate under the transmission of the rotating frame 51 and the first transmission rod 52, thereby driving the opening and closing and adjustment of the blade 2.

[0022] See Figures 1-4 The remote transmission component includes a base 8, an electric component 9 is provided on the base 8, the output end of the electric component 9 is connected to a ball joint 10, and one end of the ball joint 10 is connected to a crank 12 through a second transmission rod 11. One end of the crank 12 is connected to a door hinge 6. The electric component 9 is a drive motor. Through the ball joint 10, the second transmission rod 11, and the crank 12 in the remote transmission assembly, it can both serve the purpose of transmission and transmit the power output of the electric component 9 to the door shaft 6, thus realizing the form of remote transmission. This allows the remote transmission assembly to be separated from the frame 1, thereby avoiding the influence of high temperature. Furthermore, the entire remote transmission assembly can be installed nearby in different working conditions, such as next to the pipeline, on the ground, operating platform, or bracket. After it is installed and fixed, the crank 12 in the remote transmission assembly is connected to the door shaft 6 to complete the assembly.

[0023] During operation, multiple shafts 3 can be used to install corresponding blades 2, and both ends of the blades can be mounted on the frame 1 via bearings 4. This allows the blades 2 to rotate around the shafts 3. Since the multiple shafts 3 are located on the same side and are connected by a connecting rod assembly 5, and one end of one shaft 3 is connected to a door hinge 6, which is connected to a remote transmission assembly, the remote transmission assembly can drive one shaft 3 to rotate via the door hinge 6. Then, through the connecting rod assembly 5, it can synchronously drive all the other shafts 3 to rotate. This allows the rotation of the shafts 3 and the connecting rod assembly 5 to drive the opening and closing of the blades 2 and adjust their position. The blades 2 can stop at different angles. The scale 13, in conjunction with the connecting rod assembly 5, allows users to easily control the opening and closing angle of the blades 2 and adjust the flow rate of the pipeline medium. Therefore, the baffle gate can operate reliably and without deformation in ultra-high temperature environments, with flexible opening and closing and a long service life, greatly reducing the user's maintenance and replacement costs.

[0024] Since frame 1 is made of 310S material folded into a U-shape, it can not only ensure the structural strength of frame 1, but also improve its high temperature resistance and thus improve its service life. The entire frame 1 structure can be strengthened by the reinforcing rod 7. Since blade 2 is a hollow reinforced airfoil and elastic sealing plates are fixed on both sides of blade 2, they can interact to achieve good sealing performance when blade 2 is fully closed.

[0025] Each rotating frame 51 in the linkage assembly 5 can be installed at one end of each shaft 3, and two adjacent rotating frames 51 can be connected by multiple first transmission rods 52. Therefore, when one of the shafts 3 rotates, it can synchronously drive the other shaft 3 to rotate under the transmission of the rotating frame 51 and the first transmission rod 52, thereby driving the opening and closing and adjustment of the blade 2.

[0026] Through the ball joint 10, the second transmission rod 11, and the crank 12 in the remote transmission assembly, it can both serve the purpose of transmission and transmit the power output of the electric component 9 to the door shaft 6, thus realizing the form of remote transmission. This allows the remote transmission assembly to be separated from the frame 1, thereby avoiding the influence of high temperature. Furthermore, the entire remote transmission assembly can be installed nearby in different working conditions, such as next to the pipeline, on the ground, operating platform, or bracket. After it is installed and fixed, the crank 12 in the remote transmission assembly is connected to the door shaft 6 to complete the assembly.

[0027] In summary, this device maintains structural stability and does not deform under ultra-high temperature operating conditions, is reliable in use, has flexible switching, and a long service life, greatly reducing the user's maintenance and replacement costs.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
