Description

Technical Field

[0001] The present invention relates to the welding technology of a reaction kettle, and particularly relates to a welding device for processing the end cover of a chemical reaction kettle. Background Art

[0002] A reaction kettle is a comprehensive reaction vessel. According to the design of the structure, function and configuration accessories of the reaction kettle under reaction conditions, it is an essential and important link to process chemical raw materials through the reaction kettle in the chemical production process. When using the reaction kettle to process chemical raw materials, not only the stirring speed and temperature of the chemical raw materials need to be considered, but also the changes in the stirring speed and temperature at different processing stages need to be considered.

[0003] In the Chinese invention patent with the publication number CN111571109A, an auxiliary welding device for the end cover of a gas storage cylinder is disclosed. This auxiliary welding device for the end cover of a gas storage cylinder uses two end cover positioning mechanisms on the left and right to adsorb and fix the end cover of the gas storage cylinder by negative pressure, thus avoiding the end cover from falling and shifting, facilitating the assembly of the cylinder body on the end cover, and realizing the rapid assembly of the end cover and the cylinder body; the negative pressure adsorption method can apply force from the outside and is non-destructive to the outer wall of the end cover, and the adsorption and separation are more convenient. The distance between the first support plate and the second support plate can be adjusted to meet the needs of fixing the cylinder body and the end cover in the early stage and the need of clamping the three together in the later stage. Synchronous rotation is used to ensure that when the end covers at both ends are processed, the end cover and the cylinder body can be stably assembled, avoiding the separation of the end cover and the cylinder body during the welding process.

[0004] When the existing equipment is in use, since both the end cover and the end of the reaction kettle are arc-shaped and smooth structures during the assembly of the end cover and the end of the reaction kettle, it is easy for the end cover to become loose after being fitted with the end of the reaction kettle, resulting in the end cover being prone to falling off. Therefore, during welding, the end cover is prone to local misalignment, affecting the overall quality. Therefore, a welding device for processing the end cover of a chemical reaction kettle has been developed. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Embodiment: Please refer to Figures 1 - 10 , a welding device for processing the end cover of a chemical reaction kettle, including a support plate 1. A correction plate 11 is slidably installed on one side of the support plate 1. The reaction kettle and the end cover are preliminarily positioned through the support plate 1 and the correction plate 11.

[0039] In this solution, an electric telescopic rod is arranged at the lower end of the support plate 1. The support plate 1 is driven to move through the electric telescopic rod. The support plate 1 is used to support the reaction kettle and cooperate with the support plate 1 to adjust the reaction kettle until it stops at the optimal position.

[0040] A component with anti-slip function such as rubber is arranged at the end of the correction plate 11. The end cover is limited by the correction plate 11.

[0041] Furthermore, a positioning assembly 3 is assembled on the outer surface of the support plate 1. The reaction kettle is preliminarily limited through the positioning assembly 3. Among them, the positioning assembly 3 includes a positioning plate 312 slidably connected to the end of the support plate 1. At the same time, an arc-shaped block 311 is fixedly installed at the end of the positioning plate 312, and a bottom plate 31 is slidably installed on one side of the arc-shaped block 311.

[0042] In this embodiment, the inner wall of the positioning plate 312 is arc-shaped and is used to limit the outer surface of the reaction kettle. At the same time, an extension rod is arranged at the end of the positioning plate 312, and the end of the extension rod is slidably connected to the inner wall of the chute opened at the end of the support plate 1, thereby limiting the positioning plate 312. A moving groove is opened on one side of the bottom plate 31. By adjusting the position of the arc-shaped block 311, it is made applicable to different scenarios, and the moved arc-shaped block 311 is fixed by bolts.

[0043] One side of the bottom plate 31 is fixedly installed with support columns, and the lower ends of the support columns are rotatably installed with bases. Thus, when the positioning plate 312 is attached to the outer surface of the reaction kettle, slight adjustment can be made to make the bottom plate 31 parallel to the reaction kettle. At the same time, protective columns are arranged on both sides of the bottom plate 31, which are used to support the unused bottom plate 31 to ensure the overall stability.

[0044] Furthermore, a power shaft 32 is fixedly installed at the end of the bottom plate 31. A limiting rod 33 is fixedly installed on the outer surface of the power shaft 32. At the same time, a moving plate 34 is slidably installed on the outer surface of the limiting rod 33, and a docking block 341 is fixedly installed at the end of the moving plate 34.

[0045] Specifically, equipment with power output such as a motor is fixedly installed at the end of the bottom plate 31. The bottom plate 31 is driven to rotate by the motor. At the same time, when the bottom plate 31 rotates, the power shaft 32 is synchronously driven to rotate. Since the limiting rod 33 is fixedly installed on the outer surface of the power shaft 32 and the inner wall of the docking block 341 is slidably connected to the outer surface of the limiting rod 33, the docking block 341 is driven to rotate.

[0046] Furthermore, a docking shaft 35 is rotatably installed at the end of the power shaft 32. A positioning block 351 is fixedly installed on the outer surface of the docking shaft 35. At the same time, a transmission block 36 is slidably installed on the outer surface of the positioning block 351, and a clamping block 361 is fixedly installed at the end of the transmission block 36.

[0047] Specifically, the transmission block 36 is limited by the positioning block 351 arranged on the outer surface of the docking shaft 35, so that the transmission block 36 can move along the outer surface of the positioning block 351 until it reaches the optimal position and stops. At the same time, a fixing component such as a clamp is arranged at the end of the transmission block 36 to lock the transmission block 36 after it moves to a suitable position.

[0048] Furthermore, a fixing block 39 is fixedly installed at the end of the bottom plate 31 and on one side of the power shaft 32. A power component 38 is fixedly installed at the end of the fixing block 39. At the same time, a power plate 37 is fixedly installed at the output end of the power component 38, and the inner wall of the power plate 37 is clamped with the outer surface of the moving plate 34.

[0049] Specifically, the power component 38 is a device with telescopic function such as an electric telescopic rod and is connected to an external control device. At the same time, when the power component 38 is started, the power plate 37 arranged at its output end is synchronously driven to move. Since the inner wall of the power plate 37 is clamped with the outer surface of the moving plate 34, the moving plate 34 is driven to move.

[0050] When the moving plate 34 moves, it drives the docking block 341 fixedly installed at its end to move, so that it is engaged with the clamping block 361, so that when the moving plate 34 rotates, it drives the transmission block 36 to rotate synchronously with the docking shaft 35.

[0051] An annular groove is formed on the outer surface of the moving plate 34, and the inner wall of the annular groove is slidably connected to the inner wall of the power plate 37, so that when the movable plate 37 moves, it synchronously drives the moving plate 34 to move along the outer surface of the limiting rod 33 until the docking block 341 on the moving plate 34 is completely engaged with the clamping block 361 on the transmission block 36 and then stops, so that when the moving plate 34 follows the power shaft 32 to rotate, it drives the transmission block 36 to rotate.

[0052] Further, the locking assembly 2 is assembled at the end of the positioning assembly 3 to accurately dock the end cover at the end of the reaction kettle in cooperation with the positioning assembly 3; the locking assembly 2 includes a docking plate 21 clamped with the docking shaft 35, a driving member 22 is fixedly installed at the middle position of the end of the docking plate 21, and a fixing plate 23 is arranged around the end of the docking plate 21.

[0053] In this embodiment, the driving member 22 is a device with power output such as a motor and is connected to an external control device. When the driving member 22 is started, it synchronously drives the turntable 24 arranged at its output end to rotate. The end of the docking plate 21 is connected to the docking shaft 35 through a fixing component such as a bolt.

[0054] Further, the output end of the driving member 22 penetrates and extends to the outside of the fixing plate 23, and at the same time, a turntable 24 is fixedly installed at the output end of the driving member 22. A plurality of arc-shaped rods 241 are rotatably installed on the outer surface of the turntable 24, and the plurality of arc-shaped rods 241 are evenly distributed on the outer surface of the turntable 24.

[0055] A guiding groove 231 corresponding to the arc-shaped rod 241 is formed at the end of the fixing plate 23. At the same time, a guiding block 242 is rotatably installed at the end of the arc-shaped rod 241, and the outer surface of the guiding block 242 is slidably connected to the inner wall of the guiding groove 231.

[0056] Specifically, when the turntable 24 rotates, it drives the arc-shaped rod 241 rotatably installed on its outer surface to move. At the same time, when the arc-shaped rod 241 moves, it synchronously drives the guiding block 242 rotatably installed at the end of the arc-shaped rod 241 to move. The outer surface of the guiding block 242 is slidably connected to the inner wall of the guiding groove 231, so as to ensure that the guiding block 242 remains stable as a whole when moving.

[0057] Further, the end of the guiding block 242 penetrates and extends to the outside of the fixing plate 23, and at the same time, a driving plate 25 is fixedly installed at the end of the guiding block 242. A swing plate 251 is rotatably installed at the end of the driving plate 25.

[0058] Specifically, when the guiding block 242 moves, it synchronously drives the driving plate 25 fixedly installed at its end to move. Since the swinging plate 251 is rotatably installed at the end of the driving plate 25, the movable plate 26 is driven to move in cooperation with the swinging plate 251.

[0059] Further, a first adjusting plate 28 is rotatably installed at the end of the turntable 24. A supporting block 281 is rotatably installed at the end of the first adjusting plate 28. A second adjusting plate 29 is rotatably installed at one end of the supporting block 281 away from the first adjusting plate 28. Multiple groups of movable plates 26 are rotatably installed on the outer surfaces of the first adjusting plate 28 and the second adjusting plate 29, and the multiple groups of movable plates 26 are evenly distributed on the outer surfaces of the first adjusting plate 28 and the second adjusting plate 29. Connecting rods 27 are rotatably installed at both ends of the movable plate 26, and adjacent two connecting rods 27 are rotatably connected to each other.

[0060] Specifically, when the movable plate 26 moves under force, it drives the first adjusting plate 28 rotatably installed at its end to rotate, so that the connecting rods 27 rotatably installed at both ends of the movable plate 26 move synchronously, expanding outward or contracting toward the middle synchronously.

[0061] When the first adjusting plate 28 rotates around the supporting block 281, the second adjusting plate 29 remains stable. Furthermore, the movable plate 26 rotatably installed on the first adjusting plate 28 moves, and the movable plate 26 on the second adjusting plate 29 remains stable and moves synchronously with the connecting rod 27, thus realizing the expansion or contraction operation.

[0062] Further, a protective block 291 is rotatably installed at the end of the second adjusting plate 29, and the end of the protective block 291 is in contact with the end of the correction plate 11.

[0063] Specifically, by making the protective block 291 in contact with the correction plate 11, and after the correction plate 11 is in contact with the end cover, it is ensured that the second adjusting plate 29 remains stable.

[0064] Further, a clamping block 271 is clamped at the connection part of the two connecting rods 27, and the outer surface of the clamping block 271 is in contact with the outer surface of the end cover.

[0065] Specifically, when the connecting rod 27 moves, it synchronously drives the clamping block 271 clamped at its end to move, thereby limiting the outer surface of the end cover and cooperating with the correction plate 11 to fix the end cover.

[0066] When fixing the end cover, cooperate with the support plate 1 to drive the reaction kettle to move until the end of the reaction kettle is in contact with the end cover and then stop. At the same time, drive the bottom plate 31 to rotate, and cooperate with the arc-shaped block 311 to drive the positioning plate 312 to rotate along the outer surface of the reaction kettle, so as to ensure that the locking assembly 2 fixedly arranged at the middle position of the bottom plate 31 is in the centered position.

[0067] When the swing plate 251 is forced to move, it drives the movable plate 26 to move. A baffle is rotatably installed at the end of the movable plate 26. The outer surface of the end cover is fixed by the movement of the movable plate 26, and the clamping block 271 provided on the connecting rod 27 is used to further limit the end cover.

[0068] When the bottom plate 31 rotates, it synchronously drives the entire locking assembly 2 to rotate, so that the end cover rotates. At the same time, the support plate 1 slowly moves towards one end of the end cover until the end cover is completely attached to the end of the reactor and then stops. The connection after stopping is detected. When the contact surface is not flat enough, the locking assembly 2 is driven to continue rotating to grind the uneven part flat, ensuring the flatness of the contact between the reactor and the end cover, and welding the end cover and the reactor after the fitting is completed. Thereby improving the overall welding efficiency and reducing the errors and deformations during the welding process that may be caused by the uneven contact surface between the reactor and the end cover.

[0069] The control device can select a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller Unit), which is composed of an arithmetic unit, a controller, a memory, input and output devices, etc., and is equivalent to a miniature computer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes more on self-supply (without external hardware) and cost savings. Its greatest advantage is its small size, which can be placed inside the instrument, but its storage capacity is small, the input and output interfaces are simple, and the power consumption is low.

[0070] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
