Abstract
Description
Technical Field
[0001] This invention relates to the field of flange sealing surface processing technology, and in particular to a device for processing and repairing the sealing surface of a reactor flange. Background Technology
[0002] Reactors are commonly used closed reaction equipment in the chemical, pharmaceutical, and food industries. During operation, they often contain pressure, temperature, and corrosive media. The equipment consists of a vessel body, a vessel cover, and various connecting pipes. All connection parts rely on flange structures for docking. The flange sealing surface is a precise annular contact surface where flanges fit together. The flange sealing surface, in conjunction with a gasket, is tightened with bolts to achieve a tight fit between the end faces, isolating the flow of internal and external media and ensuring the overall airtightness of the reactor. It is suitable for pressure-bearing, corrosion-resistant, and aseptic production conditions.
[0003] Patent CN119035658A discloses a flange sealing surface processing device, including a processing table, a chuck, and a sliding table. A cutting head is arranged above the sliding table, and a protective cover is provided on the sliding table. The protective cover can restrict the waste material thrown out by the flange during the turning process, thus providing protection. A flip plate is provided at the top of the inner wall of the protective cover to block the waste material stuck in the flange recess. The inner wall of the protective cover in the clockwise rotation direction of the flip plate is provided with a power unit. The airflow sprayed from the end of the gas tank covers the recess on the flange. When the waste material remaining in the recess passes through, the instantaneous thrust of the airflow causes the waste material to be dislodged from the recess, thereby reducing the waste material residue in the recess and ensuring the normal operation of the cutting head. Moreover, the sprayed airflow can suppress splashed refrigerant, providing a good protective effect.
[0004] There are still some problems during the flange manufacturing process.
[0005] Flanges are core components for connecting pipelines, reactors, and other equipment. The machining accuracy of their sealing contact surfaces directly determines the sealing performance and reliability of the assembly. Currently, traditional flange machining often uses simple manual clamping and positioning, lacking a dedicated limiting structure. It is difficult to accurately position and constrain the inner and outer rings of the flange simultaneously, and deviations and shaking are prone to occur during machining. This leads to large deviations in the flatness and coaxiality of the flange sealing contact surfaces, excessive machining dimensional errors, and subsequent problems such as leakage and poor fit during assembly, resulting in low yield and poor processing efficiency. Summary of the Invention
[0006] The purpose of this application is to provide a device for machining and repairing the sealing surface of a reactor flange, which realizes the synchronous limiting and fixing of the inner and outer rings of the flange through positioning and limiting components, and then completes the precision machining of the sealing contact surface with the help of machining components, thereby improving machining accuracy and production stability.

It also includes a positioning component, a limiting component, and a processing component. The positioning component is disposed on the frame for fixing the flange.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Example: Reference Figure 1 - Figure 8The device shown is a processing and repair device for the sealing surface of a reactor flange. It includes a device body 1 with mounting holes 101 at the four corners of the device body 1. A first column 102 is fixedly connected to the four corners of the top surface of the device body 1. A carrying plate 103 is fixedly connected to the top of the first column 102. A second column 104 is fixedly connected to the four corners of the carrying plate 103. A frame 105 is fixedly connected to the top of the second column 104. It also includes a positioning component, a limiting component, and a processing component. The positioning component is set on the frame 105 for fixing the flange. The limiting component is set on both sides of the top surface of the frame 105 to work in conjunction with the positioning component. The processing component is set on the frame 105 for processing the flange.
[0025] Specifically, it should be noted that the first motor 2, the second motor 403, and the third motor 407 are all electrically connected to the control unit via wires. Their specific working principles are based on existing technologies and will not be elaborated upon here.
[0026] In one embodiment of this invention, the positioning component includes a first motor 2 fixedly installed at the center of the bottom surface of the carrier plate 103. A threaded rod 201 is fixedly connected to the output end of the first motor 2. A sleeve 202 is threadedly connected to the threaded rod 201. Several sets of first hinge seats 203 are fixedly installed on the surface of the sleeve 202. A linkage plate 204 is rotatably connected to the first hinge seat 203. The other end of the linkage plate 204 is rotatably connected to a second hinge seat 205, which is fixedly installed. On the bracket 206, a horizontal plate 207 is fixedly connected to the inner side of the bracket 206. The two sides of the horizontal plate 207 are slidably connected to the slide rod 208. One end of the slide rod 208 is fixedly connected to a collar 209, and the other end of the slide rod 208 is fixedly connected to a bracket 210. The bracket 210 is fixedly installed on the bottom surface of the frame 105. A main shaft 211 is fixedly connected to the top of the bracket 206. A sliding sleeve 212 is sleeved on the main shaft 211, and a tray 213 is fixedly connected to the bottom end of the sliding sleeve 212.
[0027] Specifically, the flange to be processed is placed on the tray 213, and then the first motor 2 operates to rotate the threaded rod 201. The rotation of the threaded rod 201 causes the sleeve 202 to move. The movement of the sleeve 202 pushes the cross plate 207 on the bracket 206 to move laterally on the slide rod 208 through the linkage plate 204. The movement of the bracket 206 causes the sliding sleeve 212 on the main shaft 211 to fit against the inner ring of the flange for limiting.
[0028] As one embodiment of this invention, the limiting component includes a pair of bearing seats 3 fixedly installed on both sides of the top surface of the frame 105. A side rod 301 is fixedly connected between the pair of bearing seats 3. A pair of sliders 302 are slidably connected to the side rod 301. A spring 303 is sleeved on the side rod 301. The two ends of the spring 303 are fixedly connected to one side of the bearing seat 3 and one side of the slider 302, respectively. A pin 304 is fixedly connected to the slider 302. An arm plate 305 is rotatably connected to the pin 304. A shaft 306 is rotatably connected to the other end of the arm plate 305. A positioning wheel 307 is rotatably connected to the middle end of the shaft 306.
[0029] Specifically, when the sliding sleeve 212 limits the inner ring of the flange, a pair of bearing seats 3 are fixedly connected to the top two sides of the frame 105, and a side rod 301 is fixedly connected between the pair of bearing seats 3. A slider 302 is slidably connected to the side rod 301. The slider 302 slides on the side rod 301 by the elastic force of the spring 303. The movement of the slider 302 pushes the arm plate 305 to move through the pin 304. The movement of the arm plate 305 causes the positioning wheel 307 on the shaft 306 to fit against the outer ring of the flange, thereby facilitating the limiting of the outer ring of the flange.
[0030] In one embodiment of this invention, the processing assembly includes a first support plate 4 fixedly installed on one side of the frame 105. A first rotating shaft 401 is rotatably connected to the first support plate 4. A processing disk 402 is fixedly connected to the bottom end of the first rotating shaft 401. The top end of the first rotating shaft 401 is fixedly connected to the output end of a second motor 403. The second motor 403 is fixedly installed on the first support plate 4. A shelf 404 is fixedly connected to the other side of the frame 105. A cylinder 405 is fixedly installed on the shelf 404. The telescopic end of the cylinder 405 is fixedly connected to a second support plate 406. A third motor 407 is fixedly installed at the top of the second support plate 406. A second rotating shaft 408 is fixedly connected to the output end of the third motor 407. A drive wheel 409 is fixedly connected to the bottom end of the second rotating shaft 408.
[0031] Specifically, when it is necessary to rotate the flange to facilitate the processing of the sealing surface, the cylinder 405 pushes the second support plate 406. A third motor 407 is fixedly installed on the second support plate 406, and the output end of the third motor 407 is fixedly connected to the second rotating shaft 408. A drive wheel 409 is fixedly connected to the bottom end of the second rotating shaft 408. The movement of the second support plate 406 causes the drive wheel 409 to fit against the outer ring of the flange. The operation of the third motor 407 causes the drive wheel 409 to rotate the flange. Then, the operation of the second motor 403 causes the processing disc 402 on the first rotating shaft 401 to perform processing and repair work on the sealing surface of the flange.
[0032] The working principle of this invention is as follows: The flange to be processed is placed on the tray 213, and then the first motor 2 operates to rotate the threaded rod 201. The rotation of the threaded rod 201 causes the sleeve 202 to move. The movement of the sleeve 202 pushes the horizontal plate 207 on the bracket 206 to move laterally on the slide rod 208 through the linkage plate 204. The movement of the bracket 206 causes the sliding sleeve 212 on the main shaft 211 to fit against the inner ring of the flange for limiting.
[0033] When the sliding sleeve 212 limits the inner ring of the flange, a pair of bearing seats 3 are fixedly connected to the top two sides of the frame 105, and a side rod 301 is fixedly connected between the pair of bearing seats 3. A slider 302 is slidably connected to the side rod 301. The slider 302 slides on the side rod 301 by the elastic force of the spring 303. The movement of the slider 302 pushes the arm plate 305 to move through the pin 304. The movement of the arm plate 305 causes the positioning wheel 307 on the shaft 306 to fit against the outer ring of the flange, thereby facilitating the limiting of the outer ring of the flange.
[0034] When the flange needs to be rotated to facilitate machining of the sealing surface, cylinder 405 pushes the second support plate 406. A third motor 407 is fixedly installed on the second support plate 406, and the output end of the third motor 407 is fixedly connected to the second rotating shaft 408. A drive wheel 409 is fixedly connected to the bottom end of the second rotating shaft 408. The movement of the second support plate 406 causes the drive wheel 409 to fit against the outer ring of the flange. The operation of the third motor 407 causes the drive wheel 409 to rotate the flange. Then, the operation of the second motor 403 causes the machining disc 402 on the first rotating shaft 401 to perform machining and repair work on the sealing surface of the flange.
[0035] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
