It is commonly used in petrochemical, rubber, pesticide, dye, pharmaceutical and other industries to complete sulfonation, nitration, hydrogenation, hydrocarbonization, polymerization, condensation and many other processes of organic dyes and intermediates.

[0003] For example, the existing Chinese invention patent with publication number CN116984809A discloses "An automated production system for glass-lined reactors", which includes a base plate, on which a welding mechanism, a clamping mechanism, a V-shaped support block and a positioning mechanism are arranged in sequence, the welding mechanism can weld the connection between the head and the reactor body, the clamping mechanism can clamp the head and the outside of the reactor body at the same time, the reactor body is placed on the V-shaped support block, and the positioning mechanism can position the head and the reactor body; the positioning mechanism includes a positioning base, a support baffle is slidably connected to the positioning base, the support baffle is connected to a first cross bar, the first cross bar is slidably connected to the second cross bar, the second cross bar is fixedly connected to a second motor, the second motor is connected to a second screw, and the first The cross bar is provided with a threaded hole and is threadedly connected to the second screw rod. The end of the second cross bar is fixedly connected to the positioning support plate. The third motor is fixedly connected to the inside of the positioning support plate. The third motor is connected to an active bevel gear. The active bevel gear is rotatably set on the surface of the positioning support plate. The active bevel gear can drive four positioning groups evenly distributed around it to move. The positioning group includes a driven bevel gear. The driven bevel gear is meshed with the active bevel gear. The driven bevel gear is connected to the third screw rod. The third screw is rotatably connected to the positioning support plate through an auxiliary plate. The external thread of the third screw rod is connected to a second nut. The second nut is slidably connected to the groove on the surface of the positioning support plate. The second nut is fixedly connected to the positioning support rod. The positioning support rod is fixedly connected to a positioning cylindrical rod. The positioning cylindrical rod is horizontally set.

[0004] When in use, the working process is as follows: S1, firstly, the kettle body 88 is placed on the V-shaped support block 7 by means of a lifting machine, and the four positioning cylindrical rods 517 of the positioning mechanism 5 are respectively pressed against the inner wall of the kettle body 8 and extend a small section of the kettle body 8, and then the head 9 is placed at the end of the kettle body 8 and plugged into the outside of the positioning cylindrical rods 517 for positioning connection; S2, then the clamping mechanism 4 is moved to a suitable position, and the three adjusting nuts 434 are respectively rotated so that the clamping roller 432 and the special-shaped clamping block 433 are separated. Separately clamp the kettle body 8 and the head 9 to fix their relative positions; S3, welding: first move the welding mechanism 3 to insert the connecting block 61 into the connecting hole 600 to complete the connection between the annular mounting plate 42 and the rotating circle 33, and then start the driving motor 352. The driving motor 352 drives the rotating circle 33 to rotate through the meshing gear 351 and the gear ring 350. The rotation of the rotating circle 33 drives the annular mounting plate 42 connected thereto to rotate synchronously. In this process, circumferential welding is performed through the welding gun head 34.

[0005] However, the invention places the kettle body on a V-shaped support block and uses a positioning cylindrical rod on the positioning mechanism that extends a small section of the kettle body to support the head. The head is easy to fall, and the kettle body and the head need to be moved relative to each other during the concentricity process. The head or the kettle body needs to be lifted up, which makes it easy for the head or the kettle body to slip, resulting in a poor concentricity effect.

[0006] For another example, the publication number is, which includes the following steps: Step 1: The positioning process of the first-level kettle body 32 and the second-level kettle body 33. During the positioning process of the first-level kettle body 32 and the second-level kettle body 33, the staff places the first-level kettle body 32 and the second-level kettle body 33 on the welding device base 42, and ensures that the positioning component 2 is inserted at the junction of the first-level kettle body 32 and the second-level kettle body 33. At this time, the slider 35 is located at the center position of the slide groove 34, and then the five-level telescopic electric cylinder 38 is driven to move, thereby fixing the relative position of the slider 35 and the adjustment seat 19, and then the four-level The telescopic electric cylinder 14 moves, thereby holding the inner sides of the first-stage kettle body 32 and the second-stage kettle body 33 through the positioning component 2, so that the first-stage kettle body 32 and the second-stage kettle body 33 are aligned; Step 2: The adjustment process of the four-stage telescopic electric cylinder 14 is moved once, and the five-stage telescopic electric cylinder 38 moves back. At this time, the slider 35 can slide relative to the adjustment seat 19, and then the first-stage drive motor 43 is driven to rotate forward, and the rotating shaft 1 rotates forward accordingly, thereby driving the slider 35 to move to one end edge of the slide groove 34; Step 3: Alignment of the outer welding mechanism 6 and the inner welding mechanism 7 During the welding process, the positions of the outer welding mechanism 6 and the inner welding mechanism 7 are adjusted by driving the first-level telescopic electric cylinder 4, the outer telescopic electric cylinder 11, and the inner telescopic electric cylinder 12, so that the welding gun heads on the inner welding mechanism 7 and the outer welding mechanism 6 are respectively aligned with the inner and outer sides of the weld between the first-level kettle body 32 and the second-level kettle body 33; Step 4: A welding process, during the welding process, the second-level driving motor 44 is started, thereby driving the inner welding mechanism 7 and the outer welding mechanism 6 to move synchronously, so that the inner and outer sides of the first-level kettle body 32 and the second-level kettle body 33 are aligned. Synchronous welding can be carried out on the outside; Step 5: The adjustment process of the secondary movement of the four-stage telescopic electric cylinder 14. When the positioning component 2 interferes with the inner welding mechanism 7, the first-stage telescopic electric cylinder 4 is driven to return, and then the first-stage drive motor 43 is driven to reverse, and the rotating shaft 1 is reversed accordingly, driving the slider 35 to move to the other end of the slide groove 34, and then the first-stage telescopic electric cylinder 4 moves, and then the second-stage drive motor 44 drives the inner welding mechanism 7 and the outer welding mechanism 6 to move, and then the four-stage telescopic electric cylinder 14 and the blocking position of the connecting platform 15 can be welded.

[0007] This invention still positions the primary kettle body and the secondary kettle body on the base 42, and inserts the positioning component 2 at the junction of the primary kettle body 32 and the secondary kettle body 33, and supports the inner sides of the primary kettle body 32 and the secondary kettle body 33 through the positioning component 2, so that the primary kettle body 32 and the secondary kettle body 33 are aligned. The positioning component 2 in this positioning method needs to bear a large supporting force, and when the positioning component 2 positions the junction of the primary kettle body 32 and the secondary kettle body 33, the other ends of the primary kettle body 32 and the secondary kettle body 33 will be slightly lifted, and the primary kettle body 32 and the secondary kettle body 33 cannot maintain a completely horizontal state. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a method for manufacturing a glass-lined reactor in view of the current status of the prior art, so as to reduce the bearing force of the positioning assembly when welding the first-level reactor body and the second-level reactor body, and improve the positioning accuracy of the first-level reactor body and the second-level reactor body.

[0009] The technical solution adopted by the present invention to solve the above technical problem is: a method for manufacturing a glass-lined reactor, characterized in that it comprises the following steps:

[0010] Step S1, guiding and hoisting the first-level kettle body, inflating and centering, hoisting the top of the first-level kettle body, inserting it from the top of the centering cylinder, extending the telescopic part on the center plate, inserting the inner support rod group into the first-level kettle body, and the outer end of the inner support part limits and guides the inner wall of the first-level kettle body.

Figure 6 As shown, an upper inner support assembly and a lower inner support assembly are arranged on the central shaft 51, the telescopic member 5 is a hollow linear motor 501, the central shaft 51 passes through the hollow linear motor 501 and is fixedly erected on the central disk 4, the lower inner support assembly includes a lower slide plate 81, the output end of the linear motor 501 is connected to the lower slide plate 81, a plurality of lower sleeves 82 are sleeved between the mounting plate 6 and the lower slide plate 81 on the central shaft 51, and a plurality of lower scissor fork assemblies are radially arranged between the mounting plate 6 and the lower slide plate 81 with the central shaft 51 as the center. Preferably, There are four lower scissor fork assemblies, and they are evenly arranged. Each lower scissor fork assembly includes lower scissor rods 83 hinged to each other. The inner ends of two adjacent lower scissor rods 83 are hinged to the lower sleeve 82, and the outer ends of two adjacent lower scissor rods 83 are hinged to the same lower inner support ball 84. The outer end of the lower scissor rod 83 at the lower end is slidably set on the lower slide 81, the inner end of the lower scissor rod 83 at the lower end is hinged to the lower sleeve 82, and the outer end of the uppermost lower scissor rod 83 is slidably set on the lower side of the mounting plate 6.

Preferably, there are 4 upper scissor fork assemblies, and they are evenly arranged In this way, each upper scissor fork assembly includes upper scissor rods 87 hinged to each other, the inner ends of two adjacent upper scissor rods 87 are hinged to the upper sliding sleeve 88, the outer ends of two adjacent upper scissor rods 87 are hinged to the same upper inner support ball 89, the outer end of the lowermost upper scissor rod 87 is slidably set on the upper slide plate 86, the inner end of the lowermost upper scissor rod 87 is hinged to the upper sliding sleeve 88, the outer end of the uppermost upper scissor rod 87 is slidably set on the lower side surface of the upper fixed plate 511, and the inner end of the uppermost upper scissor rod 87 is hinged to the upper sliding sleeve 88.

[0037] At this time, the inner support member 53 is an inner support ball structure. When the lower inner support ball 84 performs limiting guidance and tensioning on the first-stage kettle body 71, the linear motor 501 drives the lower slide plate 81 to slide up and down, thereby driving the lower scissor rods 83 in the lower scissor fork assembly to open and close with each other, so that the lower inner support ball 84 acts on the inner wall of the first-stage kettle body 71; when the upper inner support ball 89 performs limiting guidance and tensioning on the second-stage kettle body 72, the hollow motor 85 drives the upper slide plate 86 to slide up and down, thereby driving the upper scissor rods 87 in the upper scissor fork assembly to open and close with each other, so that the upper inner support ball 89 acts on the inner wall of the second-stage kettle body 72.

[0038] In addition, if Figure 1 As shown, the present invention also discloses a method for manufacturing a glass-lined reactor, comprising the following steps:

[0039] Step S1, the first-level kettle body 71 is guided and hoisted, and inflated and centered. The top of the first-level kettle body 71 is hoisted and inserted from the top of the centering cylinder 1. The telescopic member 5 on the center plate 4 is extended, and the inner support rod group is inserted into the first-level kettle body 71. The outer end of the inner support member 53 limits and guides the inner wall of the first-level kettle body 71. The inflatable ring 2 on the lower inner wall of the centering cylinder 1 is inflated, and the inflatable ring 2 is evenly wrapped on the outer wall of the first-level kettle body 71. The inflatable ring 2 drives the first-level kettle body 71 to move slightly for centering until the first-level kettle body 71 is slowly placed on the rotating ring 3 of the bracket 31;

[0040] Step S2, the guide hoist of the secondary kettle body 72 is installed on the primary kettle body 71, and the secondary kettle body 72 is inflated and centered. The secondary kettle body 72 is hoisted from the top of the centering cylinder 1. When entering the centering cylinder 1, the outer end of the inner support member 53 limits and guides the inner wall of the secondary kettle body 72. At the same time, the inflatable ring 2 on the upper inner wall of the centering cylinder 1 is inflated, and the inflatable ring 2 is evenly wrapped on the outer wall of the secondary kettle body 72. The inflatable ring 2 drives the secondary kettle body 72 to move slightly for centering. Finally, the secondary kettle body 72 is slowly placed on the upper end surface of the primary kettle body 71.

[0041] Step S3, internal and external welding, the internal support rod group is tensioned, the internal support member 53 is pressed against the inner wall of the first kettle body 71 and the second kettle body 72, the rotating motor 41 drives the central disk 4 to rotate, the first kettle body 71 and the second kettle body 72 rotate slowly and synchronously, the inner welding cylinder 64 drives the inner welding head 65 to extend, the outer welding cylinder 66 drives the outer welding head 67 to extend, and the inner welding head 65 and the outer welding head 67 respectively perform synchronous welding on the junction of the first kettle body 71 and the second kettle body 72;

[0042] Step S4, unloading and taking out the kettle, the inner welding joint 65 and the outer welding joint 67 retract, the rotating motor 41 stops, the inner support rod group retracts, the inner support member 53 loses its effect on the inner wall of the kettle body, the inflation ring 2 deflates and shrinks, and the kettle body is hoisted and removed from the centering cylinder 1.

[0043] Furthermore, in step S4, the deflation and contraction of the inflatable ring 2 may also occur first in step S3, before the rotating motor 41 drives the kettle body to rotate when the inner welding joint 65 and the outer welding joint 67 are welded, thereby reducing the resistance of the inflatable ring 2 to the rotation of the kettle body.

[0044] Furthermore, in steps S1 and S2, when the first-stage kettle body 71 and the second-stage kettle body 72 are hoisted into the centering cylinder 1, the rotating motor 41 drives the center disk 4 to rotate in the opposite direction, the inner support rod group rotates, and the inner support member 53 rotates synchronously while serving as a limit guide for the first-stage kettle body 71 and the second-stage kettle body 72. During this process, the rotating ring 3 is in a stationary state.

[0045] Furthermore, the inner support members 53 in the same inner support rod group are extended and retracted synchronously, the extension and retraction of each inner support rod group is hydraulically controlled, and the extension and retraction amounts of different inner support rod groups can be different.

[0046] Furthermore, the inner support member 53 is an inner support disk, on which an electromagnet is arranged. When the inner support member 53 is in the process of limiting and guiding the first-level kettle body 71 or the second-level kettle body 72, the electromagnet is in a de-energized state. When the inner support member 53 is in the process of tensioning the first-level kettle body 71 and the second-level kettle body 72, the electromagnet is energized, and the inner support disk is completely adsorbed on the inner side walls of the first-level kettle body and the second-level kettle body.

[0047] Furthermore, during the synchronous rotation of the primary kettle body 71 and the secondary kettle body 72 , the inflatable rings 2 on the inner wall of the centering cylinder 1 also rotate synchronously.

[0048] Furthermore, in step S3, during the welding process of the internal welding head 65, on the mounting plate 6, the ring gear motor 63 drives the inner ring gear 61 to rotate via the driving gear 62, and the inner ring gear 61 drives the inner welding cylinder 64 to rotate along with the inner ring gear 61, and the rotation direction of the inner ring gear 61 is opposite to the rotation direction of the first-stage kettle body 71.

[0049] Furthermore, the inner support member 53 may also adopt an inner support ball structure, specifically, as Figure 6 As shown, in the process of the lower inner support ball 84 limiting the guidance and tensioning the first-stage kettle body 71, the linear motor 501 drives the lower slide plate 81 to slide up and down, drives the lower scissor rods 83 in the lower scissor fork assembly to open and close with each other, so that the lower inner support ball 84 acts on the inner wall of the first-stage kettle body 71; in the process of the upper inner support ball 89 limiting the guidance and tensioning the second-stage kettle body 72, the hollow motor 85 drives the upper slide plate 86 to slide up and down, drives the upper scissor rods 87 in the upper scissor fork assembly to open and close with each other, so that the upper inner support ball 89 acts on the inner wall of the second-stage kettle body 72.

[0050] In summary, the present invention simultaneously hangs the first-level kettle body 71 and the second-level kettle body 72 in the centering cylinder 1, and the first-level kettle body 71 and the second-level kettle body 72 are stacked together to reduce the bearing force of the positioning assembly. At the same time, with the limiting guidance and clamping effect of the inner support rod group, the inflatable ring 2 on the inner wall of the centering cylinder 1 can center the first-level kettle body 71 and the second-level kettle body 72.
