[0003] Traditional high-temperature resistant exhaust gas cushions are usually made of metal, ceramic fiber, glass fiber, asbestos-free composite materials or high-temperature resistant synthetic fibers. The high-temperature resistance of these materials is usually not good enough.

[0018] The present invention discloses a high temperature resistant tail gas cushion of mica composite process and a processing device thereof, which has the following beneficial effects:

[0019] 1. The high-temperature resistant exhaust cushion processing device of the mica composite process improves the processing technology of the exhaust cushion body during the processing of the exhaust cushion body, and combines a metal sheet, a high-temperature resistant fiber layer and a mica layer. The mica layer is the core layer, which provides high-temperature resistance and insulation performance; the high-temperature resistant fiber layer enhances the overall strength and toughness of the exhaust cushion body; the metal sheet provides additional support and sealing effects.

Therefore, during use, the equipment has a long maintenance cycle and good stability.

[0020] 2. The high temperature resistant exhaust cushion processing device of the mica composite process adopts a plasma treatment unit to perform plasma treatment on the mica layer in order to improve the bonding effect between the mica layer and the metal sheet. The plasma treatment unit generates high energy plasma to physically and chemically modify the surface of the mica layer material, thereby forming an etching area and improving its surface properties. At the same time, the active particles in the plasma will interact with the surface of the mica layer material, resulting in the breaking and recombination of the surface chemical bonds, forming new active groups, which help to improve the wettability and adhesion of the mica surface, making it easier to combine with the adhesive glue.

[0021] 3. The high-temperature resistant tail gas cushion processing device of the mica composite process makes it easy to adjust the position of the movable shaft on the rotating arm through the design of the adjustment component. Therefore, when the rotating arm drives the movable shaft to rotate, it is convenient to adjust the rotation radius of the movable shaft. The smaller the rotation radius of the movable shaft, the smaller the reciprocating motion spacing of the movable bracket, so that it is convenient to adjust the moving spacing of the plasma machine head, and then to adapt to the plasma treatment of mica layers of different widths. Through the design of the sleeve part and the telescopic part, it is convenient to adjust the length of the connecting rod, thereby adjusting the position of the plasma machine head, so that the plasma machine head can be aligned with the bottom of the mica layer, thereby ensuring a good composite effect of the tail gas cushion body.

[0022] 4. The high-temperature resistant exhaust cushion processing device of the mica composite process, through the design of the clamping component, when the two sets of pressure rollers extrude the metal sheet, the high-temperature resistant fiber layer and the mica layer, the spring will be compressed synchronously, and the elastic force of the spring will react on the clamping rod and the pressure roller to ensure good fit between the pressure roller and the exhaust cushion body, stable pressing process, and improved processing effect of the exhaust cushion body.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0036] The embodiment of the present application provides a high-temperature resistant exhaust gas cushion with a mica composite process and a processing device thereof, which solves the problem that the high-temperature resistance of traditional high-temperature resistant exhaust gas cushions is usually not good enough. In a high-temperature environment with a temperature exceeding 1000 degrees Celsius, the performance of traditional materials is easily affected, resulting in a decrease in sealing performance or failure, and it is also easy to release toxic substances under high temperature conditions, posing a potential threat to the environment and human health. At the sealing position, the texture is soft and the mechanical strength is not high, which is easily affected by the external environment and damaged or performance degraded. Therefore, many high-temperature resistant exhaust gas cushions have a short maintenance cycle during use, and are prone to the problem of weakened equipment sealing effect and malfunction.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The embodiment of the present invention discloses a high temperature resistant tail gas cushion processing device of mica composite process.

[0039] The plasma processing unit 2 includes a support frame 201 disposed on the processing device body 1 and a movable frame 202 slidably connected to the support frame 201, and a plasma machine head 203 is disposed on the movable frame 202;

[0040] The pressing unit 4 comprises a fixed support 401 arranged on the processing device body 1 and an electric push rod 402 fixedly connected to the fixed support 401 . A push plate 403 is arranged at the output end of the electric push rod 402 , and a pressure roller 404 is arranged on the push plate 403 .

[0041] The high temperature resistant exhaust gas cushion processing device of the mica composite process improves the processing technology of the exhaust gas cushion body 5 during the processing of the exhaust gas cushion body 5, and combines the metal sheet 501, the high temperature resistant fiber layer 502 and the mica layer 503. The mica layer 503 is the core layer, providing high temperature resistance and insulation performance; the high temperature resistant fiber layer 502 enhances the overall strength and toughness of the exhaust gas cushion body 5; and the metal sheet 501 provides additional support and sealing effects.

[0042] At the same time, based on the above combination, in order to improve the bonding effect between the mica layer 503 and the metal sheet 501, a plasma treatment unit 2 is used to perform plasma treatment on the mica layer 503. The plasma treatment unit 2 generates high-energy plasma to physically and chemically modify the surface of the mica layer 503 material, thereby forming an etching area 5031 and improving its surface properties. At the same time, the active particles in the plasma will interact with the surface of the mica layer 503 material, resulting in the breaking and recombination of the surface chemical bonds, forming new active groups. These active groups help to improve the wettability and adhesion of the mica surface, making it easier to combine with the adhesive glue.

[0043] A guide rail seat 2011 and a motor support plate 2012 are provided on the support fixing frame 201, the movable bracket 202 is slidably connected to the guide rail seat 2011, the motor support plate 2012 is fixedly connected to the motor body 204, a rotating arm 205 is provided at the output end of the motor body 204, a movable shaft 2051 is provided on the rotating arm 205, a connecting rod 206 is rotatably connected to the movable shaft 2051, and the connecting rod 206 is rotatably connected to the movable bracket 202;

[0044] In the plasma processing unit 2, the design of the motor body 204, the rotating arm 205, the movable shaft 2051 and the connecting rod 206 facilitates the reciprocating motion of the movable bracket 202, thereby driving the plasma machine head 203 to reciprocate, so that the plasma machine head 203 provides plasma treatment to the moving mica layer 503, ensuring that the plasma treatment is uniform and fully covered, thereby improving the quality of the tail gas cushion body 5;

[0045] When the motor body 204 is working, the motor body 204 drives the rotating arm 205 to rotate, the rotating arm 205 drives the movable shaft 2051 to rotate, the movable shaft 2051 drives the connecting rod 206 to move, the connecting rod 206 drives the movable bracket 202 to move, and the movable bracket 202 drives the plasma machine head 203 to move, so that the plasma machine head 203 reciprocates;

[0046] The rotating arm 205 is provided with an adjustment assembly 207, which includes a first screw rod 2071 rotatably connected to the rotating arm 205 and an adjustment block 2072 slidably connected to the rotating arm 205, the adjustment block 2072 is threadedly connected to the first screw rod 2071, and the adjustment block 2072 is fixedly connected to the movable shaft 2051;

[0047] The device is designed with an adjustment component 207 so that the movable shaft 2051 can be easily adjusted in position on the rotating arm 205. Therefore, when the rotating arm 205 drives the movable shaft 2051 to rotate, the rotation radius of the movable shaft 2051 can be easily adjusted. The smaller the rotation radius of the movable shaft 2051, the smaller the reciprocating motion spacing of the movable bracket 202, thereby facilitating the adjustment of the moving spacing of the plasma machine head 203, thereby adapting to the plasma treatment of mica layers 503 of different widths.

[0048] The connecting rod 206 includes a sleeve portion 2061 and a telescopic portion 2062. The design of the sleeve portion 2061 and the telescopic portion 2062 facilitates the adjustment of the length of the connecting rod 206, thereby adjusting the position of the plasma machine head 203 so that the plasma machine head 203 can be aligned with the bottom of the mica layer 503.

[0049] The sleeve part 2061 is rotatably connected to the movable shaft 2051. The movable bracket 202 is provided with a fixed shaft 2021. The fixed shaft 2021 is rotatably connected to the telescopic part 2062. The telescopic part 2062 is provided with a rack 209. The rack 209 is movably inserted in the sleeve part 2061. The sleeve part 2061 is provided with a clamping assembly 208 for clamping the rack 209.

[0050] When adjusting the length of the connecting rod 206, the rack 209 is directly slid along the inside of the sleeve 2061 for adjustment. After the adjustment, the position of the rack 209 is clamped and limited by the clamping assembly 208, which is simple to operate.

[0051] The clamping assembly 208 includes a stopper seat 2081 fixedly connected to the sleeve portion 2061 and a second screw rod 2082 threadedly connected to the stopper seat 2081. A tooth block 2083 is rotatably connected to the second screw rod 2082, and the tooth block 2083 is meshed with the rack 209.

[0052] When the clamping assembly 208 is performing the clamping operation of the rack 209, the operation is simple. The second screw rod 2082 can be directly rotated. When the second screw rod 2082 rotates, it drives the tooth block 2083 to move, and finally the tooth block 2083 slides along the inside of the limit seat 2081 and engages with the rack 209.

[0053] The gluing unit 3 comprises a gluing support 301 fixedly connected to the processing device body 1 and a gluing mounting seat 302 movably connected to the gluing support 301, and a gluing nozzle 303 and a glue supply hose 304 are arranged on the gluing mounting seat 302;

[0054] The gluing unit 3 has a simple structure, and uses a glue supply pipe 304 to supply glue to the gluing nozzle 303. The gluing nozzle 303 is limited in position by a gluing mounting seat 302. The gluing bracket 301 and the gluing mounting seat 302 are connected by bolts. Therefore, the gluing nozzle 303 is easy to install and maintain later, ensuring uniform gluing and improving the stability of the exhaust cushion body 5.

[0055] A pressing assembly 405 is provided between the push plate 403 and the pressure roller 404. The pressing assembly 405 includes a sleeve seat 4051 fixedly connected to the push plate 403 and a pressing rod 4053 fixedly connected to the bearing seat of the pressure roller 404. The pressing rod 4053 is slidably connected in the sleeve seat 4051. A spring 4052 is fixedly connected between the sleeve seat 4051 and the pressing rod 4053.

[0056] Through the design of the clamping component 405, when the two groups of pressure rollers 404 extrude the metal sheet 501, the high-temperature resistant fiber layer 502 and the mica layer 503, the spring 4052 will be compressed synchronously, and the elastic force of the spring 4052 will react on the clamping rod 4053 and the pressure roller 404 to ensure good fit between the pressure roller 404 and the exhaust gas cushion body 5, stable pressing process, and improved processing effect of the exhaust gas cushion body 5. Before the exhaust gas cushion body 5 is pressed, it is glued and bonded by the gluing unit 3. After gluing, it is finally extruded by the clamping unit 4 to form the exhaust gas cushion body 5.

[0057] The fixed support 401 and the electric push rod 402 are connected by bolts, and the fixed support 401 and the electric push rod 402 are easy to install, so that the installation and maintenance of the clamping unit 4 are convenient, ensuring the stability of the equipment, and further ensuring the stability of the processing process of the exhaust cushion body 5.

[0059] When the second glue layer 505 is bonded between the metal sheet 501 and the mica layer 503, the second glue layer 505 can easily penetrate into the etching area 5031, thereby increasing the contact area and adhesion between the mica layer 503 and the second glue layer 505, thereby improving the bonding effect of the second glue layer 505 on the metal sheet 501 and the mica layer 503, and ensuring the good stability of the exhaust cushion body 5.
