Description

Technical Field

[0001] This invention belongs to the field of power equipment manufacturing technology, specifically relating to automated equipment and methods for reactor surface treatment. Background Technology

[0002] After production, reactors require surface polishing and painting to ensure insulation performance, corrosion resistance, and appearance quality. However, reactors are typically large and complex (involving painting of multiple parts such as planetary carriers, inner and outer walls, and top surfaces), placing extremely high demands on the precision and uniformity of surface treatment.

[0003] Traditional manual sanding and painting methods have obvious drawbacks: on the one hand, manual operation is inefficient and cannot meet the needs of large-scale production, and the spraying quality is unstable, with poor control over the uniformity and thickness of paint application, affecting the product's service life and failing to meet the high-precision processing requirements of the complex structure of large reactors; on the other hand, during manual sanding and painting, dust and paint mist are not effectively treated, resulting in a harsh working environment that not only seriously threatens the health of operators (such as inhaling dust which can easily cause respiratory diseases, and exposure to harmful fumes which may lead to poisoning), but also does not conform to the environmental protection concept of modern green production. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention aims to provide an automatic grinding and painting device for reactors.

[0005] This automatic reactor grinding and painting equipment, operating according to its process, includes a transport support module, a grinding module, and a painting module. The transport support module transports the reactor to a designated working area; the grinding module precisely grinds the surface of the reactor; and the painting module applies multi-sided painting to the ground reactor.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the invention.

[0033] It should also be noted that, in order to avoid unnecessary obscuring of the present invention, the accompanying drawings only show the structures and / or processing steps closely related to the present invention, while omitting other details that are not closely related to the present invention.

[0034] Specific Implementation Plan 1: (e.g.) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, this specific embodiment adopts the following technical solution. This embodiment includes a reactor 1, a transport support module 2, a grinding module 3, and a painting module 4. The reactor 1 is a large-sized reactor. The transport support module 2 transports the reactor 1 to a designated position for operation and keeps the reactor 1 and the rotating platform 204 in synchronous operation when necessary. The grinding module 3 performs precise and uniform grinding on the surface of the reactor 1. The painting module 4 performs painting treatment on the reactor 1 after further grinding.

[0035] like Figure 5As shown, the guide rail 201 in the transport support module 2 is driven by the geared motor 203 to transport the rotating platform 204 and the reactor 1 on it to a suitable position for subsequent grinding and painting.

[0036] Furthermore, such as Figure 6 The three-phase asynchronous motor 205 inside the rotating platform 204 starts, and the horizontal transmission is converted into vertical transmission through the bevel gear 206 and transmitted upward. The torque output is increased through the reduction gearbox 207, which drives the platform to move. At the same time, the coil in the electromagnetic chuck 208 is also energized, generating an attraction force that causes the reactor 1 to rotate together with the rotating platform 204.

[0037] Furthermore, such as Figure 1 and Figure 3 On the lifting platform 301, the lead screw motor 303 starts, raising the robotic arm 305, which is closely connected to the lead screw slider 304, to a certain height; at this time, the upper arm 306 and the lower arm 307 open and close according to the position of the reactor 1, slowly approaching the reactor 1 until the designated grinding position.

[0038] like Figure 7 When the grinding disc 309 of the vacuum grinding head 308 touches the side of the reactor 1, the stepper motor 310 starts, driving the grinding disc 309 to move and perform grinding. At the same time, the sensor 311 provides pressure feedback for this process: the pressure is transmitted through the grinding disc 309 to the connecting plate 315. Since the connecting plate 316 is fixed to the slider 313, the slider 313 is compressed, and the spring 312 behind it is compressed. The deformation of the spring 312 is fed back to the sensor 314 to obtain the pressure value, and then controls the feed amount of the upper arm 306 and the lower arm 307 to complete the pressure adjustment grinding and achieve the effect of precise grinding.

[0039] At the same time, the vacuum cleaner 318 works normally during the polishing process, absorbing the dust generated during polishing.

[0040] After sanding, the painting process is carried out, such as... Figure 4 The polishing module 3 shown; activates the first multi-directional spraying slide rail 401 and the second multi-directional spraying slide rail 408 to perform full-area spraying on the reactor 1; the process is as follows:

[0041] With the rotary platform 204 in operation, the fourth lead screw guide 409 and the fifth lead screw guide 409 are activated.

[0042] The rail 410 transports the telescopic rod 411 and the second spray gun 412 to the appropriate painting position. At the same time, the telescopic rod 411 can also be adjusted to reach the position. The second spray gun 412 has an infrared ranging function to provide spraying distance feedback, which can also reach the painting position. After the second spray gun 412 is in place, the spray gun is started to spray paint the side of the reactor 1 from bottom to top.

[0043] After the side spraying is completed, stop the operation of the rotating platform 204 to stop the reactor 1 from moving.

[0044] Start the second lead screw guide rail 403 and the third lead screw guide rail 405 to move the spraying connecting rod 404 directly above the gap of the reactor 1 frame. Then start the first lead screw guide rail 402 to move the spraying connecting rod 404 into the reactor 1 until it reaches the appropriate spraying point and stops. Use the infrared ranging on the second spraying rod 411 and the second spray gun 412 to control the distance between the rod and the inner wall in a small range. After reaching the spraying point, start the second spray gun 412 to spray the inner wall of the reactor 1 from bottom to top.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
