Description

Technical Field

[0001] The present invention mainly relates to the technical field of rotary equipment processing, and specifically relates to a rotary equipment and a manufacturing method thereof. Background Art

[0002] Insoluble sulfur, also known as polymerized sulfur, is a homopolymer of sulfur. It is non-toxic, flammable, and a yellow powder. The so-called insoluble sulfur refers to polymerized sulfur that is insoluble in carbon disulfide. It is a polymer modified variety of ordinary sulfur. It is currently mainly used in the production of automobile radial tires. It is currently the best rubber vulcanizer and accelerator. The rotary equipment is the core dynamic equipment in the high-performance insoluble sulfur project. The shell of the equipment is equivalent to a giant rotating shaft, and the manufacturing precision requirements are high. The axial runout and circumferential runout of the roller ring, rotary joint flange, and gear ring on the shell are controlled within 0.5mm.

[0003] Rotary equipment is an industrial equipment, mainly used for uniform mixing, turning, drying, heating or cooling of various solid materials. It realizes the material processing process through rotating containers. Rotary equipment is widely used in chemical, building materials, metallurgy, food, pharmaceutical and other industries. Rotary equipment has the characteristics of both dynamic and static equipment. It must have good dynamic balance performance (stability, accuracy), and the characteristics of static equipment such as long (long length), large (large volume), heavy (large mass), complex (many internal and external accessories), and precise (high precision requirements). It integrates multiple disciplines such as mechanical design, equipment manufacturing, and electrical control. The requirements for manufacturing accuracy are particularly high, especially in terms of deviations in parameters such as ellipticity, concentricity, and runout. The requirements are very strict. The ovality of the cylinder segment and the straightness between cylinder segments are required to be controlled at the millimeter level. In the process of manufacturing the rotary equipment, our company's light-transmitting device (application number: 202310595066.9) is required to accurately detect the concentricity and straightness between cylinder segments. However, due to the huge size of the equipment itself, when the laser is irradiated along the central axis of the cylinder segment, due to the diffraction effect, the limitation of the optical system, atmospheric turbulence and the divergence of the laser beam itself, the laser beam gradually diverges during propagation, resulting in the diameter of the light spot increasing with the increase of distance. In long-distance measurement, the increase of the light spot will lead to the amplification of the measurement concentricity error, thereby affecting the accuracy of the straightness detection. Summary of the invention

[0004] The technical solution of the present invention aims at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technologies. Specifically, the present invention mainly provides a rotating device and a manufacturing method thereof, so as to solve the technical problem raised in the above background technology that in the process of detecting the concentricity and straightness of the rotating device through a light-transmitting device, the laser spot will become larger, thereby affecting the accuracy of the straightness detection.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A rotary device, comprising a rigid track, a plurality of roller frames with adjustable angles are arranged on the rigid track, a cylinder arranged linearly is arranged on the roller frame, a rolling ring structure is arranged on the thick-walled cylinder at both ends, a supporting circle light transmission detection mechanism is movably installed in a part of the thin-walled cylinder at the middle position, and the spacing between the supporting circle light transmission detection mechanisms is adjustable; The circle-supporting light-transmitting detection mechanism includes a circle-supporting base, a convex lens and four pulley groups. The convex lens is located in the light-transmitting hole at the center of the circle-supporting base, and the convex lens and the circle-supporting base are detachably connected. Convex lenses with different parameters are adapted according to the length of the cylinder. The four pulley groups are equidistantly arranged around the outer edge of the circle-supporting base.

[0006] Preferably, two pulley blocks located at opposite positions are both equipped with motors via bolts, and an output end of each motor is connected to a pulley shaft in the corresponding pulley block.

[0007] Preferably, an elastic reset portion with an annular structure is provided at the outer edge of the circular support base, and an annular metal spring is embedded in the elastic reset portion.

[0008] Preferably, a light-transmitting platform is provided at one end of the rigid track, a height-adjustable tripod bracket and a theodolite on the tripod bracket are provided on the light-transmitting platform, and the laser of the theodolite passes through a convex lens.

[0009] Preferably, the rolling ring structure includes a plurality of positioning blocks, a rolling ring body and a limit block which are evenly spaced and arranged around the outer wall of the cylinder. A plurality of clamping blocks are evenly spaced and arranged around the inner wall of the rolling ring body. Each of the clamping blocks is clamped with a clamping slot which is arranged on the corresponding positioning block, and the limit block is inserted between two adjacent positioning blocks.

[0010] Preferably, a support platform is provided below each of the rolling ring structures, and the support platform contacts the outer wall of the rolling ring body.

[0011] A method for manufacturing a rotary device, the manufacturing method specifically comprising a barrel section processing technology, a rolling ring processing technology and a light transmission detection technology; The specific steps of the light transmission detection process are as follows: S1 Preliminary preparation: Place the cylinder on the roller frame and adjust it. The roller frame has a solid foundation to prevent the equipment from shaking during the inspection. Then place the light-transmitting platform at one end of the rigid track, set up the tripod, and install the theodolite on the tripod; S2 Adjust the theodolite: adjust the tripod bracket, align the theodolite initially, use the laser beam to adjust the theodolite, make the beam of the theodolite pass through the nearest circular support base, and check whether the light spot farthest from the theodolite passing through the circular support base is concentric with the nearest one; S3 spot adjustment: According to the overall length of the rotary device, select a suitable convex lens and install it on the round support base, then turn on the motor to drive the corresponding pulley group to move, so that the round support base moves in the cylinder, and change the distance between the convex lenses to adjust the spot size of the laser beam so that the final spot is consistent with the size of the light source; S4 detection and adjustment: With the theodolite as a reference, check from far to near whether the light beam can pass through the light-transmitting holes on the supporting circular base. If it cannot pass through, use the roller frame to slightly adjust the position of the corresponding cylinder until the light beam passes through the light-transmitting hole. When only the light beam is adjusted, the direction of the theodolite light beam remains unchanged. If it can pass through completely, the light transmission test is qualified.

[0012] Preferably, the rolling ring processing process specifically includes the following steps: S1 Confirm the heating temperature of the roller ring. During the heating process of the roller ring body, the thermal expansion of the roller ring must be determined. Too high a heating temperature will eliminate the cold work hardening of the steel and reduce the hardness value of the roller ring surface. After the roller ring is heated and expanded, it must meet the minimum size so that it can be smoothly inserted into the rotating equipment; S2 tooling design: the roller body needs to be turned over after heating. The roller heat-fitting tooling adopts a semi-half structure, which is convenient for the disassembly and assembly of the tooling. Four lifting ears are set on the tooling to facilitate the turning of the roller. Safety blocks are welded on both sides of the outer ring of the roller tooling to prevent the roller from slipping during the turning process. S3 hot-fit roller, after assembling the roller body and the clamping block, they are put into the furnace for heat treatment at the same time to prevent deformation of the roller body during the heating process. The roller body is heated in a flat position. After the heating is completed, the roller body is immediately changed from a flat position to a vertical position using the lifting lug of the roller body. Before the roller body is installed, first ensure that the roller body is basically concentric with the cylinder of the rotating equipment, and then the roller body is inserted into the cylinder by moving the crane back and forth. After the roller is cooled, the roller structure fits tightly with the cylinder.

[0013] Preferably, the barrel segment processing technology includes an annular groove processing method, a barrel segment manufacturing method and a rotary joint assembly method.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention, by providing a round support base, a convex lens, a pulley block and a motor, effectively avoids the enlargement of the light spot finally formed by the theodolite during the detection of the rotating equipment, thereby preventing the decrease in the detection accuracy of the concentricity and straightness of the rotating equipment from being caused by the enlargement of the light spot due to the excessive size of the rotating equipment and the divergence of the light beam itself, and ensures that the size of the light spot finally formed is consistent with that at the light source, thereby improving the detection accuracy of the concentricity and straightness, reducing the error, and overcoming the defects of the traditional technology. Real-time monitoring during the manufacturing process can effectively control the quality, ensure the accuracy, and improve the efficiency of the welding work. The better the control of the concentricity and straightness is, the smaller the jump is during the operation, and the easier it is to assemble. The installation is simple and convenient, which can effectively ensure product quality and reduce manufacturing costs, and utilizes the elastic reset part and the elastic structure of the annular metal spring to reset the round support base. When the angle between the round support base and the inner wall of the cylinder is greater than 90 degrees, it is corrected and reset by 90 degrees to achieve the purpose of automatic reset with a small offset, so that the round support bottom is in a vertical state, thereby ensuring the vertical state of the convex lens and ensuring that the light beam can pass through the lens. No manual correction is required, which is very convenient and reduces the labor intensity of the staff. The cooperation between the convex lens and the round support base optimizes the spatial layout of the support circle and the detection structure, supports the inner wall of the cylinder, ensures the roundness of the thin-walled cylinder, and avoids deformation of the cylinder during welding.

[0015] (2) The present invention provides stable support for the rotating equipment by setting the positioning block and the rolling ring body. After the rolling ring body is heated, the stability of the connection is further improved due to the cooperation between the slot, the block and the limit block. As the rolling ring body and the block cool down, the rolling ring body is tightly installed on the cylinder body, and the average gap between the rolling ring body and the positioning block is effectively controlled to be between 0 and 0.13 mm, preventing the cylinder body from moving during rotation, providing a stable welding environment, and ensuring the subsequent welding quality. The rolling ring body and the positioning block are not fixed by the traditional welding method, which will be worn after a certain period of use. The rolling ring body can be easily replaced, and the cylinder body will not be deformed when the rolling ring body is removed from the cylinder.

[0025] The tube section is manufactured as follows: Manufacturing of thick-walled cylinder section at S1 end: the cylinder 3 at the feeding end is cut according to the layout and CNC to ensure that the two opposite sides of the cylinder 3 are parallel to each other, and the diagonal lengths are equal, the diagonal deviation is not more than 2mm, and the circumference deviation is not more than 3mm. After the cylinder is rolled and welded, it is rounded and the edge angle is strictly controlled to be no more than 2mm. In the natural state, the difference between the maximum inner diameter and the minimum inner diameter on the same section is no more than 10mm. After the longitudinal seam is qualified by non-destructive testing, the cylinder 3 is rounded by special tooling to ensure that the difference between the maximum inner diameter and the minimum inner diameter on the same section of the cylinder 3 is no more than 2mm; S2 Manufacturing of intermediate thin-walled cylinder section: The intermediate thin-walled cylinder 3 is reasonably divided into sections according to the total length of the equipment, the position of the reinforcement ring, the pipe connection, etc. The intermediate section cylinder 3 of this equipment is divided into six sections, 1 to 6, and the manufacturing method of the end cylinder section is the same as that of the intermediate cylinder section (process flow: the main manufacturing process of the cylinder section: material acceptance → cutting → making longitudinal seam groove → rolling → welding longitudinal seam → rounding → non-destructive testing → polishing the inner wall of the cylinder → installing the support round tooling → processing the annular seam groove → geometric dimension inspection → marking the reinforcement ring position line → welding the reinforcement ring → waiting for assembly); S3 cylinder segment assembly: assembling the middle cylinder 3 parts and the two end cylinder 3 parts → light transmission detection process → circumferential seam welding (try not to rotate the base welding) → assembling the two end cylinder 3 parts → placing the two roller ring bodies 53 on the roller frame 2 → light transmission detection process → welding (process monitoring) → non-destructive testing → placing the rotary equipment roller ring body 53 on the roller frame 2 for horizontal test run → using a dial indicator to detect the runout of the roller ring body 53, the end cylinder 3 and other positions → marking inside the cylinder 3 to assemble the pipe support plate → pipe support welding (pay attention to deformation) → marking and opening holes to assemble the welded pipe (other pre-welded parts such as oil blocking rings are not assembled for the time being) → the fuselage is completed (the cutting and production of some parts are not introduced).

[0026] The specific steps of the light transmission detection process are as follows: S1 Preliminary preparation: Place the cylinder 3 on the roller frame 2 and adjust it. The roller frame 2 has a solid foundation to prevent the equipment from shaking during the detection process. Then place the light-transmitting platform 6 at one end of the rigid track 1, set up the tripod bracket 7, and install the theodolite 8 on the tripod bracket 7; S2: Adjust the theodolite 8: adjust the tripod support 7, initially align the theodolite 8, use the laser beam to adjust the theodolite 8, make the beam of the theodolite 8 pass through the nearest circular support base 41, and check whether the light spot farthest from the theodolite 8 passing through the circular support base 41 is concentric with the nearest one; S3 Light spot adjustment: According to the overall length of the rotary device, select a suitable convex lens 42 and install it on the round support base 41, then turn on the motor 44 to drive the corresponding pulley group 43 to move, so that the round support base 41 moves in the cylinder 3, and change the distance between the convex lenses 42 to adjust the light spot size of the laser beam, so that the final light spot is consistent with the size of the light source; S4 detection and adjustment: taking the theodolite 8 as a reference, detect from far to near whether the light beam can pass through the light-transmitting holes on the supporting circular base 41. If it cannot pass through, the position of the corresponding cylinder 3 is slightly adjusted by the roller frame 2 until the light beam passes through the light-transmitting holes. When only the light beam is adjusted, the direction of the light beam of the theodolite 8 remains unchanged. If it can pass through completely, the light transmission detection is qualified.

[0027] The rolling ring processing technology specifically includes the following steps: S1 Confirm the heating temperature of the roller ring. During the heating process of the roller ring body 53, the thermal expansion of the roller ring needs to be determined. Too high a heating temperature will eliminate the cold work hardening of the steel and reduce the hardness value of the roller ring surface. After the roller ring is heated and expanded, it must meet the minimum size so that it can be smoothly inserted into the rotating equipment; Thermal expansion = thermal expansion coefficient × total length × temperature change. The thermal expansion coefficient of steel is 12.2 × 10-6, and the total length is 3030 mm. In order to reduce the impact of heating on the surface hardness of the rolling ring, the heating temperature is confirmed to be 220 ° C. The temperature change = heating temperature (220 ° C) - room temperature (20 ° C) = 200 ° C. The thermal expansion can be calculated as 12.2 × 10-6 × 3030 × 200 = 7.39 mm. S2 tooling design, the roller body 53 needs to be turned over after heating. The roller heat-fitting tooling adopts a semi-half structure, which is convenient for the disassembly and assembly of the tooling. Four lifting ears are set on the tooling to facilitate the turning of the roller. Safety blocks are welded on both sides of the outer ring of the roller tooling to prevent the roller from slipping during the turning process. S3 heat-fits the roller. After the roller body 53 and the clamping block 54 are assembled, they are put into the furnace for heat treatment at the same time to prevent the roller body 53 from being deformed during the heating process. The roller body 53 is heated in a flat position. After the heating is completed, the roller body 53 is immediately changed from a flat position to an upright position using the lifting ears of the roller body 53. Before the roller body 53 is installed, first ensure that the roller body 53 is basically concentric with the cylinder 3 of the rotating equipment. By moving the crane back and forth, the roller body 53 is inserted into the cylinder 3. After the roller is cooled, the roller structure 5 and the cylinder 3 are tightly fitted.

[0028] Example 2, please refer to the attached Figure 2 and 3 As shown, the two pulley blocks 43 located at relative positions are both equipped with motors 44 by bolts, and the output end of each motor 44 is connected to a pulley shaft in the corresponding pulley block 43. The motor 44 provides a driving force for the movement of the pulley block 43, so as to enable the circular support base 41 to move in the cylinder 3, change the distance between the convex lenses 42, and adjust the size of the light spot. An elastic reset portion 411 with an annular structure is provided at the outer edge of the circular support base 41, and an annular metal spring 412 is embedded in the elastic reset portion 411. Through the elastic reset portion 411 and the annular metal spring 412, the vertical state of the convex lens 42 is ensured, and it is ensured that the light beam can pass through the lens without manual correction, which is very convenient.

[0029] Example 3, please refer to the attached Figure 1 and 4As shown, a light-transmitting platform 6 is provided at one end of the rigid track 1, and a height-adjustable tripod bracket 7 and a theodolite 8 on the tripod bracket 7 are provided on the light-transmitting platform 6, and the laser of the theodolite 8 passes through the convex lens 42, and the position of the theodolite 8 is adjusted through the tripod bracket 7, so that the light moves along the central axis of the cylinder 3, and the rolling ring structure 5 includes a plurality of positioning blocks 51, a rolling ring body 53 and a limit block 55 which are arranged on the outer wall of the cylinder 3 at equal intervals, and a plurality of positioning blocks 51, a rolling ring body 53 and a limit block 55 are arranged on the inner wall of the rolling ring body 53 at equal intervals. There are a number of blocks 54, each of which is connected with a slot 52, and the slot 52 is arranged on the corresponding positioning block 51. The limit block 55 is inserted between two adjacent positioning blocks 51. Through the mutual cooperation among the block 54, the slot 52 and the limit block 55, after the roller body 53 is installed on the cylinder body 3, the asynchronous rotation between the roller body 53 and the cylinder body 3 is avoided. A support platform 9 is arranged under each of the roller structures 5, and the support platform 9 is in contact with the outer wall of the roller body 53. The support platform 9 is used to assist the rotation of the rotary device.

[0030] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
