Description

Technical Field

[0001] The present invention belongs to the technical field of the manufacture of the stirring shaft of a reaction kettle, and particularly relates to a manufacturing device and an installation structure of the stirring shaft of a reaction kettle. Background Art

[0002] In the production processes of many industrial fields such as modern chemical industry, pharmaceuticals, and food, as the core reaction vessel, the reaction kettle plays a crucial role. It is used to carry out various chemical reactions, material mixing, heating and cooling processes, etc. The stirring shaft is a key component in the reaction kettle to achieve uniform mixing of materials, heat and mass transfer, and promote the efficient progress of the reaction. The performance and installation quality of the stirring shaft are directly related to the overall operation effect, production efficiency, and product quality stability of the reaction kettle. With the continuous expansion of the industrial production scale and the increasing requirement for the refinement of production processes, the specifications and sizes of reaction kettles are getting larger and the internal reaction conditions are becoming more complex and demanding. For example, in large-scale chemical synthesis reactions, the volume of the reaction kettle may reach dozens or even hundreds of cubic meters, and it is required that the stirring shaft operates stably in a medium environment with high viscosity, high corrosiveness, high temperature and high pressure, ensuring that the materials can be fully mixed and evenly heated, and avoiding problems such as local overheating and uneven reaction. This poses extremely high requirements for the manufacturing precision, strength, corrosion resistance of the stirring shaft, and the accuracy and reliability of installation.

[0003] When an existing manufacturing device and installation device of a stirring shaft are in use, for example, the Chinese invention patent with the publication number of CN116000382A discloses a manufacturing device and an installation device of a stirring shaft, which relates to the field of the manufacture and installation of a stirring shaft. The manufacturing device includes a fixed-distance rotary machine, and the fixed-distance rotary machine includes a support wheel set. The support wheel set is used to support the ends of the four-corner shaft and the five-corner shaft, so that the axis of the four-corner shaft and the axis of the five-corner shaft are parallel to each other and at the same height; a constant-speed ratio drive mechanism, and the constant-speed ratio drive mechanism is used to drive the four-corner shaft and the five-corner shaft to rotate synchronously at a predetermined speed ratio. The installation device includes a fixed-distance rotary machine and a self-centering walking frame. The manufacturing device can achieve precise positioning when installing the scrapers on the four-corner shaft and the five-corner shaft, preventing the situation of rotational interference between the scrapers on the four-corner disc and the five-corner disc; the installation device includes the fixed-distance rotary machine in the manufacturing device. When installing the stirring shaft, the fixed-distance rotary machine can ensure the stability of the accuracy of the four-corner shaft and the five-corner shaft in the stirring shaft, achieving the effect of cooperating with the self-centering walking frame to install the stirring shaft.

[0004] However, during installation, the stirring shaft can only be horizontally fed into the reaction kettle, and its function is relatively single. When the shape of the reaction kettle shell is vertical, the above device cannot feed the stirring shaft into the reaction kettle shell, resulting in poor overall practicality of the device and a relatively single installation structure. In view of this, we have proposed a manufacturing device and an installation structure of the stirring shaft of a reaction kettle for vehicle lighting. Summary of the Invention

[0005] The purpose of the present invention is to provide a manufacturing device and an installation structure for the stirring shaft of a reaction kettle to solve the problems raised in the above-mentioned background technology.

A gasket is arranged on one side where the first fixing bolt and the mounting plate are close to each other, and the gasket is sleeved on the first fixing bolt. Another set of gaskets is arranged on one side where the first nut and the moving plate are close to each other. The first fixing bolt can be inserted into the mounting plate and the moving plate, and fixed by the first nut, so that the mounting plate can be installed on the moving plate.

[0010] In the above technical solution, further, the clamping plate is composed of two arc-shaped plate bodies hinged together.

[0011] The present invention provides an installation structure for a stirring shaft of a reaction kettle, including: A fixed seat, the lower end of the fixed seat is fixedly connected to the upper right side of the base.

The sides where the two activity plates are close to each other are meshed with the gear.

[0022] Embodiment 1: Please refer to Figures 1-11 As shown, this embodiment provides a manufacturing device and an installation structure for a stirring shaft of a reaction kettle.

[0023] Including: a base 1, a moving component is fixedly installed on the upper left side of the base 1. The moving component includes a first ball screw 2, the first ball screw 2 is connected to the left side inside the base 1, a first motor 3 is fixedly installed at the front end of the left side of the base 1, a first ball screw sleeve 6 is sleeved on the left side of the first ball screw 2, and the upper end of the first ball screw sleeve 6 is connected to an adjusting rod 7, and the other end of the adjusting rod 7 is connected to a bottom plate 8; the pushing component includes a second ball screw 10, the second ball screw 10 is connected to the inside of the bottom plate 8, a second motor 11 is fixedly installed on the left side of the bottom plate 8, and the rotating shaft of the second motor 11 is fixedly connected to the second ball screw 10. A second ball screw sleeve 12 is sleeved on the left side of the second ball screw 10 of the bottom plate 8. The upper end of the second ball screw sleeve 12 is fixedly connected to a moving plate 13, and an installation plate 14 is fixedly installed on the upper right side of the moving plate 13. A clamping plate 17 is fixedly connected to the upper right side of the installation plate 14, and a stirring shaft 20 is installed inside the clamping plate 17. A fixed seat 21, the lower end of the fixed seat 21 is fixedly connected to the upper right side of the base 1. A third motor 22 is fixedly installed at the middle position of the lower end of the fixed seat 21, and a rotating rod 23 is fixedly connected to the rotating shaft of the third motor 22. A gear 24 is sleeved on the outer side of the rotating rod 23. On both the left and right sides inside the fixed seat 21, there are movable plates 25, and a fixed frame 26 is fixedly connected to the upper end of the movable plate 25. Connection frames 27 are fixedly connected to both the left and right ends of the fixed seat 21, and a movable sleeve 28 is sleeved on the connection frame 27. A limiting plate 29 is fixedly connected to the upper end of the fixed frame 26. A reaction kettle housing 30 is clamped on the side where the two limiting plates 29 are close to each other. The first motor 3 and the second motor 11 adopt DC reduction motors: such as 57BYG250C-180TF90. The advantage of the DC reduction motor (57BYG250C-180TF90) is the integrated design of a stepper motor + planetary reducer, without the need for an additional transmission mechanism, and can directly drive the ball screw or gearbox. For low-speed and intermittent motion scenarios such as the moving component (such as the first motor 3 driving the first ball screw 2) and the pushing component (such as the second motor 11 driving the second ball screw 10), the price is much lower than that of a servo motor, and it is suitable for auxiliary motion control with low precision requirements. The third motor 22 adopts a servo motor, such as Mitsubishi HF-KP1S-50A, with an in-built encoder (such as a 17-bit absolute encoder) to achieve closed-loop feedback control, with a positioning accuracy of up to ±0.01 mm and extremely small speed fluctuations. For scenarios that require high dynamic performance such as the driving of the stirring shaft 20 (such as the third motor 22) and the lifting or rotation of the reaction kettle housing 30, it can effectively suppress the influence of load fluctuations (such as changes in material resistance) on the operation stability.

[0024] Embodiment 2: This embodiment provides a manufacturing device and installation structure for the stirring shaft of a reaction kettle. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0025] Among them, there are two sets of the first ball screw 2 in total. A pulley 4 is fixedly connected to the left side of the two sets of the first ball screws 2, and the two pulleys 4 are connected by a belt 5. The right side of the first ball screw 2 is rotatably connected to the inner wall of the base 1. Limit sliders are fixedly connected to the front and rear ends of the first ball nut 6. A chute matching the limit slider is opened on the inner wall of the base 1. The rotating shaft of the first motor 3 is connected to one of the first ball screws 2. One of the pulleys 4 is sleeved on the rotating shaft of the first motor 3. Connecting the two first ball screws 2 through the belt 5 can ensure that the two screws rotate synchronously, avoiding the problem of uneven movement caused by a single motor driving a single-sided screw. In the moving component (such as the movement of the bottom plate 8), the synchronous drive of the double screws can keep the bottom plate 8 moving horizontally and smoothly, preventing tilting or jamming. The ball screw itself has a high lead accuracy (such as C7 level accuracy), and with the synchronous transmission of the belt 5, the displacement deviation between the two sides can be further reduced. The cooperation between the limit slider and the base chute ensures that the first ball nut 6 only moves axially, avoiding radial deviation and improving the positioning accuracy. The double screws jointly bear the load (such as the weight and friction of the bottom plate 8), and the force on a single screw is halved, reducing the driving torque requirement of the first motor 3. When the first motor 3 drives a single-sided screw, the other screw may suffer from insufficient lubrication or rust due to long-term idleness. The synchronous drive of the double screws can be evenly run-in, reducing the maintenance cost. The belt 5 transmission has a flexible buffering characteristic, which can absorb the impact generated by the start-stop of the first motor 3 or the sudden change of the load, protecting the screw and the first motor 3.

[0026] Embodiment 3: This embodiment provides a manufacturing device and an installation structure for a stirring shaft of a reaction kettle. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0027] Among them, the upper end of the first ball nut 6 is hingedly connected to an adjusting rod 7, and the other end of the adjusting rod 7 is hingedly connected to the lower left side of the bottom plate 8. The front and rear ends of the right side of the bottom plate 8 are rotatably connected to the connecting plate 9, and the lower end of the connecting plate 9 is fixedly connected to the base 1. Limit sliders are fixedly connected to the front and rear ends of the second ball nut 12. A chute matching the limit slider is opened on the inner wall of the bottom plate 8. The right side of the second ball screw 10 is rotatably connected to the inner wall of the bottom plate 8. The right side of the second ball screw 10 is fixed to the inner wall of the bottom plate 8 by means of a bearing or hinge, forming a simply supported beam structure, which can effectively resist the bending deformation of the screw under high-speed rotation or high load. When the pushing component (such as the moving plate 13) moves, the fixed point on the right side of the screw can reduce vibration and radial deviation, ensuring the linear motion accuracy of the second ball nut 12. The right-side rotational connection can limit the axial displacement of the screw, preventing the screw position from shifting due to thermal expansion or load impact, thereby ensuring the stable advancement of the moving plate 13.

[0028] Example 4: This example provides a manufacturing device and installation structure for the stirring shaft of a reactor. In addition to including the technical solutions of the above examples, it also has the following technical features.

[0029] Among them, the left side of the mounting plate 14 is fixedly installed on the moving plate 13 through the first fixing bolt 15. The outer surface of the first fixing bolt 15 is evenly provided with threaded grooves. The first fixing bolt 15 is threadedly inserted into the moving plate 13 and the mounting plate 14. The lower end of the first fixing bolt 15 is sleeved with a first nut 16. A gasket is provided on the side where the first fixing bolt 15 and the mounting plate 14 are close to each other, and the gasket is sleeved on the first fixing bolt 15. Another set of gaskets is provided on the side where the first nut 16 and the moving plate 13 are close to each other. The clamping plate 17 is composed of two arc-shaped plate bodies hinged together. The front ends of the two clamping plates 17 are fixed through the second fixing bolt 18. The outer surface of the second fixing bolt 18 is evenly provided with threaded grooves. The second fixing bolt 18 is threadedly inserted into the clamping plate 17. The lower end of the second fixing bolt 18 is sleeved with a second nut 19. A gasket is provided on the side where the second fixing bolt 18 and the clamping plate 17 are close to each other, and the gasket is sleeved on the second fixing bolt 18. Another set of gaskets is provided on the side where the second nut 19 and the clamping plate 17 are close to each other. Both the first fixing bolt 15 and the second fixing bolt 18 are threadedly inserted and tightened with nuts (the first nut 16, the second nut 19) to form a double locking mechanism, effectively preventing loosening. A gasket is provided at the contact between the first fixing bolt 15 and the plate, which can evenly disperse the tightening force and avoid deformation or tearing of the plate caused by local stress concentration. The mounting plate 14 is fixed on the moving plate 13 through the first fixing bolt 15, and the clamping plate 17 is hinged through the second fixing bolt 18. This design allows for quick disassembly and replacement of components, facilitating maintenance or upgrading. When it is necessary to replace the stirring shaft 20 or adjust the arc of the clamping plate 17, only the first fixing bolt 15 needs to be loosened, and there is no need to disassemble the equipment as a whole. The outer surface of the first fixing bolt 15 is provided with evenly threaded grooves, which cooperate with the first nut 16 and the gasket to achieve standardized tightening, ensuring connection strength and consistency. The threaded connection can adapt to plates of different thicknesses, avoiding irreversible deformation caused by welding or riveting.

[0030] Example 5: This example provides a manufacturing device and installation structure for the stirring shaft of a reactor. In addition to including the technical solutions of the above examples, it also has the following technical features.

[0031] Wherein, on the sides of the two groups of movable plates 25 away from each other, they are both movably clamped on the inner wall of the fixed seat 21 through T-shaped blocks. T-shaped grooves matching with the T-shaped blocks are provided on the inner wall of the fixed seat 21. Tooth teeth are evenly distributed on the sides of the two groups of movable plates 25 close to each other. The sides of the two groups of movable plates 25 close to each other are meshed with the gear 24. One end of the fixed frame 26 is fixedly connected to the movable plate 25, and the other end of the fixed frame 26 is fixedly connected to the movable sleeve 28. The connecting frame 27 is arranged in a rectangular structure. Slots matching with the connecting frame 27 are provided on the movable sleeve 28. Rubber convex strips are evenly distributed on the sides of the two groups of limiting plates 29 close to each other. The sides of the two groups of limiting plates 29 close to each other are abutted against the outer side of the reactor shell 30. The movable plate 25 is in cooperation with the T-shaped groove in the fixed seat 21 through the T-shaped block to achieve linear guidance, preventing the movable plate 25 from tilting or shifting during movement. When the gear 24 drives the movable plate 25 to move horizontally, the T-shaped block ensures that the movable plate 25 slides smoothly along the axial direction of the fixed seat 21, avoiding jamming or derailment. The tooth teeth of the movable plate 25 are meshed with the gear 24. By driving the gear 24 to rotate through the third motor 22, synchronous reverse movement (approaching or moving away from each other) of the two groups of movable plates 25 is realized. When the movable plate 25 moves, the limiting plate 29 is driven to move synchronously through the fixed frame 26, thereby realizing the clamping of the reactor shell 30. When the movable plates 25 approach each other, the limiting plates 29 gradually abut against the reactor shell 30, and the rubber convex strips provide frictional force to prevent the shell from slipping. The rubber convex strips of the limiting plate 29 can increase the contact frictional force with the reactor shell 30 and at the same time play a buffering role, avoiding scratching the surface of the reactor shell 30 due to hard contact, being applicable to reactor shells of different materials (such as stainless steel, glass) or surface roughness, and improving the versatility.

[0032] During use: Move the device to a suitable position, place the reactor shell 30 on the fixed seat 21, turn on the third motor 22. At the same time, the third motor 22 drives the rotating rod 23 to rotate. The rotating rod 23 drives the movable plate 25 to move through the gear 24. The movable plate 25 moves through the fixed frame 26. The fixed frame 26 drives the two groups of limiting plates 29 to move towards each other, so that the two groups of limiting plates 29 approach each other, and the reactor shell 30 is clamped and fixed through the limiting plates 29; Clamp the stirring shaft 20 on the two groups of clamping plates 17, insert the second fixing bolt 18 into the clamping plate 17, then sleeved the second nut 19 on the second fixing bolt 18 to fix the stirring shaft 20. The second motor 11 can be turned on. The second motor 11 drives the second ball screw 10 to drive the second ball screw sleeve 12 to drive the moving plate 13 to move. The stirring shaft 20 is pushed into the reactor shell 30 through the moving plate 13, and the staff installs it; When the reaction kettle housing 30 is in a vertical state, the first motor 3 can be turned on. The first motor 3 drives the first ball screw 2 to rotate. The first ball screw 2 drives the adjusting rod 7 to move through the first ball screw sleeve 6. The use angle of the bottom plate 8 can be adjusted through the adjusting rod 7. The bottom plate 8 can be adjusted to a vertical state, and then the moving plate 13 can be adjusted to a vertical state. The stirring shaft 20 installed on the clamping plate 17 can be adjusted to a vertical state. Then, the second motor 11 is turned on. The second motor 11 drives the second ball screw sleeve 12 to move through the second ball screw 10. The second ball screw sleeve 12 drives the stirring shaft 20 to descend through the moving plate 13. Then, the stirring shaft 20 can be sent into the reaction kettle housing 30, and the staff can install the stirring shaft 20.
