Description

Technical Field

[0001] This invention relates to the field of boron trifluoride complex technology, and more specifically to a boron trifluoride complex raw material feeding device. Background Technology

[0002] Boron trifluoride complexes are a class of stable compounds formed by boron trifluoride and ligands such as ethers, amines, and nitriles through Lewis acid-base reactions. They are widely used in alkylation, polymerization, and acylation reactions in organic synthesis, and are also key catalytic raw materials for the preparation of pharmaceutical intermediates and high-performance materials. Because these complexes exist in different states such as liquid and solid, and some products are corrosive and volatile, precise and safe material transfer and feeding are required in industrial production processes using specialized raw material feeding equipment. The stability and adaptability of this equipment directly affect production efficiency, material utilization, and operational safety.

[0003] However, existing feeding equipment generally relies on manual knob adjustment of the feeding port opening, lacking quantitative reference and depending entirely on the operator's experience. This results in a large deviation between the baffle opening and the actual feeding amount. Solid crystals are prone to feeding delays due to insufficient opening, while liquid materials are often fed excessively due to excessive opening. Both of these can cause imbalances in the reaction system. Moreover, there is no real-time feedback during the adjustment process, requiring frequent shutdowns for sampling and weighing for calibration. This not only disrupts production continuity but also causes material accumulation during shutdowns, further reducing the accuracy of subsequent feeding and seriously affecting industrial production efficiency. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a boron trifluoride complex raw material feeding device to solve the above problems.

[0012] Preferably, the feedback module includes an electric telescopic rod connected to the inner wall of the top of the support base.

The outer surface of the feeding tank is fixedly connected to four support frames.

[0015] The beneficial effects of this invention are as follows: 1. By meshing the first and second bevel gears in the control module, and with the quantitative indication structure of the dial and pointer, rotating the adjustment plate can drive the adjustment rod and gear set to precisely transmit power, thereby controlling the opening of the adjustment baffle and realizing the quantitative adjustment of the feeding amount. This avoids the problem of deviation between the opening and the actual feeding amount caused by the lack of reference in traditional manual knobs, ensuring that there is no lag in the feeding of solid crystals and no excess of liquid materials, thus ensuring the stability of the reaction system. 2. The 30-degree inclined guide plate in the solid material flow guiding module, together with the fixed installation structure of the crossbar, can guide the solid complex raw material to fall into the regulating baffle, solving the problem of poor flowability and easy accumulation of solid materials. At the same time, the regulating baffle can be quickly disassembled and cleaned through the threaded connection of the first threaded rod, the second threaded rod and the threaded groove in the disassembly and assembly component, avoiding material residue from affecting the subsequent feeding accuracy, and further improving the equipment adaptability and ease of operation. 3. The liquid material quantity adaptation module features a multi-stage throttling column with throttling orifices, along with snap-on and detachable first, second, and third plugs. The appropriate throttling orifice can be flexibly selected based on the viscosity of the liquid complex, stabilizing the liquid material feed rate. Combined with the precise quantity control of the control module, it avoids feeding deviations caused by flow rate fluctuations. Furthermore, the throttling column uses a threaded connection, allowing for easy disassembly and replacement to adapt to liquid raw materials with different properties without requiring the replacement of the entire equipment. 4. Through the cooperation of the electric telescopic rod and the moving seat in the feedback module, the electric telescopic rod adjusts the front and rear distance of the moving seat, and the front and rear position of the receiving cylinder can be adjusted according to the material receiving requirements to ensure that the receiving cylinder accurately connects with the discharge cylinder's discharge end. With the weight detection of the pressure sensor and weighing plate and the linkage feedback of the controller, the material discharge data can be obtained in real time. Operators do not need to frequently stop the machine for calibration, avoiding interruptions to production continuity. At the same time, the limit frame limits the moving seat to prevent the moving seat from shifting, which would cause the receiving cylinder to shift and the material to spill, further improving production efficiency and material utilization.

[0020] Working principle: Boron trifluoride complex raw material is stored in feeding tank 1. The raw material flows into the discharge cylinder 2 through the flange structure at the discharge end of feeding tank 1. The bearing seat 5 provides a stable installation foundation for the feedback module. The 30-degree inclined guide plate 12 in the solid material flow guiding module is fixed by the snap-fit ​​cooperation between the first installation port 13, the second installation port 14 and the crossbar 6. It can guide the solid raw material to concentrate towards the adjusting baffle 22. The adjusting baffle 22 can be flexibly disassembled and assembled through the disassembly and assembly components. The control module is used to precisely adjust the opening of the adjusting baffle 22. The liquid material flow adaptation module adapts to the liquid raw material feeding requirements. The feedback module monitors the feeding situation in real time, realizes the stable feeding of raw materials in different physical states, and solves the problem of poor adaptability of existing equipment.

[0021] Please see Figures 1 to 17The assembly includes a first mounting cylinder 27 and a second mounting cylinder 28, which are bolted to the outer surface of the discharge cylinder 2. The outer surface of the discharge cylinder 2 has two disassembly / reassembly ports 15. The outer surfaces of both the first mounting cylinder 27 and the second mounting cylinder 28 engage with the interior of the disassembly / reassembly ports 15. The inner walls of the first mounting cylinder 27 and the second mounting cylinder 28 are respectively provided with annular first toothed grooves 33 and second toothed grooves 39. A first ball bearing 29 and a second ball bearing 36 are respectively connected to the interior of the first mounting cylinder 27 and the interior of the second mounting cylinder 28. The outer surface of the ball bearing 29 and the outer surface of the second ball bearing 36 are respectively fixedly connected to the first tooth plate 30 and the second tooth plate 38. The inner ring of the first ball bearing 29 and the inner ring of the second ball bearing 36 are respectively connected to the first threaded rod 31 and the second threaded rod 35. The left end of the first threaded rod 31 is provided with a toothed column retaining groove 32. The toothed column 34 is slidably connected inside the toothed column retaining groove 32. The left end of the toothed column 34 is fixedly connected to the meshing gear 17. The outer surface of the adjusting baffle 22 is provided with two threaded grooves 40 corresponding to the first threaded rod 31 and the second threaded rod 35. The first mounting cylinder 27 and the second mounting cylinder 28 are located on the left and right sides of the adjusting baffle 22. The outer surface of each first toothed plate 30 and the outer surface of each second toothed plate 38 are slidably connected to the interior of the first toothed groove 33 and the interior of the second toothed groove 39, respectively. The outer surface of the first threaded rod 31 and the outer surface of the second threaded rod 35 are threadedly connected to the inner wall of the threaded groove 40. A prismatic groove 37 is provided at the right end of the second threaded rod 35. The control module includes a connecting seat 19 connected to the outer surface of the discharge cylinder 2 via a thread. A third ball bearing 26 is connected to the inner wall of the connecting seat 19. An adjusting rod 20 is connected to the inner ring of the third ball bearing 26. An adjusting disc 21 is fixedly connected to the front end of the adjusting rod 20. A first bevel gear 18 is connected to the outer surface of the rear end of the adjusting rod 20. A second bevel gear 16 meshes with the outer surface of the first bevel gear 18. The diameter ratio of the second bevel gear 16 is larger than that of the first bevel gear 18. The interior of the second bevel gear 16 meshes with the outer surface of the meshing gear 17. A scale 24 is connected to the front of the connecting seat 19, which is located outside the adjusting rod 20. A pointer 25 is fixedly connected to the outer surface of the adjusting rod 20, which is located in front of the scale 24.

[0022] Working principle: In the control module, the connecting seat 19 fixes the third ball bearing 26, which supports the rotation of the adjusting rod 20. Rotating the adjusting disc 21 drives the adjusting rod 20 and the first bevel gear 18 to rotate. The first bevel gear 18 meshes with the larger diameter second bevel gear 16 to achieve speed reduction and torque increase. The second bevel gear 16 meshes with the meshing gear 17 for transmission. The meshing gear 17 slides with the toothed groove 32 of the first threaded rod 31 through the toothed column 34, driving the first threaded rod 31 to rotate. At the same time, the first mounting cylinder 27 and the second mounting cylinder 28 are disassembled. The loading port 15 is fixed to the discharge cylinder 2. The first toothed plate 30 and the second toothed plate 38 on the outer surface of the first ball bearing 29 and the second ball bearing 36 inside are respectively slidably limited with the first toothed groove 33 and the second toothed groove 39 to ensure the stable rotation of the first threaded rod 31 and the second threaded rod 35. The first threaded rod 31 and the second threaded rod 35 are threadedly connected to the threaded groove 40 of the adjusting baffle 22 to achieve precise adjustment of the opening of the adjusting baffle 22. The scale 24 and the pointer 25 work together to provide quantitative reference, solving the problems of lack of basis and insufficient accuracy in traditional manual adjustment.

[0023] Please see Figures 1 to 17 A protective shell 7 is bolted to the left side of the discharge cylinder 2. A protective frame 11 is bolted to the front of the protective shell 7. A first protective door 9 is hinged to the front of the protective frame 11. A second protective door 10 is hinged to the left side of the protective shell 7.

[0024] Working principle: The protective shell 7 is fixed to the left side of the discharge cylinder 2 by bolts. The protective shell 7 protects the internal meshing gear 17 and the second bevel gear 16. The protective frame 11 on the front of the protective shell 7, together with the first protective door 9 and the second protective door 10 on the left side, can be opened and closed by hinge rotation. This facilitates the inspection and maintenance of internal components and prevents the volatile gases of the material from contacting the operators or external impurities from entering the transmission structure. Moreover, the protective shell 7 is made of transparent material, which also makes it easy to observe the adjustment of the dial 24 and pointer 25, avoids the corrosion or jamming of transmission components, and ensures the safety and stability of equipment operation.

[0025] Please see Figures 1 to 17 The liquid material quantity adaptation module includes a throttling column 8 threadedly connected to the inner wall of the bottom of the discharge cylinder 2. The top of the throttling column 8 is provided with a first throttling port 43, a second throttling port 42 and a third throttling port 41 with diameters decreasing from large to small. The first throttling port 43, the second throttling port 42 and the third throttling port 41 are respectively fitted with a first plug 44, a second plug 23 and a third plug 45.

[0026] Working principle: In the liquid material quantity adaptation module, the throttling column 8 is fixed to the bottom inner wall of the discharge cylinder 2 by threads. The diameters of the first throttling port 43, the second throttling port 42, and the third throttling port 41 at the top of the throttling column 8 decrease sequentially. According to the viscosity requirements of the liquid raw material, the corresponding throttling port is selected by snapping or disassembling the first blockage 44, the second blockage 23, and the third blockage 45. The large-diameter throttling port is selected for the high viscosity raw material, and the small-diameter throttling port is selected for the low viscosity raw material, so as to achieve stable control of the liquid raw material discharge flow rate. With the adjustment of the opening of the baffle 22, the problem of feeding deviation caused by the flow rate fluctuation of the liquid raw material is solved.

[0027] Please see Figures 1 to 17 The feedback module includes an electric telescopic rod 46 connected to the inner wall of the top of the support seat 5. The telescopic end of the electric telescopic rod 46 is connected to a movable seat 4. The upper surface of the movable seat 4 is connected to a weighing pan 56 and four positioning rods 49. The four positioning rods 49 are located outside the weighing pan 56. The outer surfaces of the four positioning rods 49 are slidably connected to a weighing plate 51. The top of the weighing pan 56 is connected to a pressure sensor 55. The weighing end of the pressure sensor 55 is in contact with the bottom surface of the weighing plate 51. A receiving cylinder 47 is provided above the weighing plate 51. The outer surface of the receiving cylinder 47 is etched with scale lines 48. The back and left sides of the movable seat 4 are connected to a controller 53 and a timer 52, respectively. The controller 53 is electrically connected to the electric telescopic rod 46 and the pressure sensor 55 through wires. A limiting ring 50 is fixedly connected to the upper surface of the weighing plate 51, and the inside of the limiting ring 50 is engaged with the bottom outer surface of the receiving cylinder 47. The upper surface of the support seat 5 is fixedly connected to the left and right sides of the movable seat 4 with limit frames 54. The side of the two limit frames 54 that are close to each other is in contact with the bottom surface of the movable seat 4. Four support frames 3 are fixedly connected to the outer surface of the feeding tank 1.

[0028] Working principle: The limiting frame 54 of the bearing seat 5 in the feedback module forms a left and right limit for the moving seat 4. The controller 53 controls the extension and retraction of the electric telescopic rod 46, which drives the moving seat 4 to move back and forth to adjust the position of the receiving cylinder 47, ensuring accurate docking with the discharge end of the discharge cylinder 2. The four positioning rods 49 on the moving seat 4 act as guides and limits on the weighing plate 51. The weighing plate 51 fixes the receiving cylinder 47 through the limiting ring 50. The weight of the raw material received by the receiving cylinder 47 is transmitted to the pressure sensor 55 through the weighing plate 51. The pressure sensor 55 transmits the weight signal to the controller 53. The timer 52 records the discharge time. The scale line 48 on the outside of the receiving cylinder 47 can help observe the discharge amount. The support frame 3 enhances the stability of the discharge tank 1, realizes real-time feedback and accurate control of the discharge amount, avoids frequent shutdowns for calibration, and ensures continuous production.

[0029] In summary, when the entire equipment is in use: First, raw materials are stored in the feeding tank 1. The support frame 3 outside the feeding tank 1 ensures the stability of the entire equipment. The raw materials flow into the discharge cylinder 2 through the flange structure at the discharge end of the feeding tank 1. If solid raw materials are added, the 30-degree inclined guide plate 12 in the solid material flow guiding module inside the discharge cylinder 2 is fixed by the snap-fit ​​cooperation between the first mounting port 13, the second mounting port 14 and the crossbar 6, guiding the solid raw materials to concentrate towards the adjusting baffle 22. At this time, the opening is adjusted by the control module, and the adjustment plate 21 is rotated to drive the adjusting rod 20 to rotate. The third ball bearing 26 in the connecting seat 19 ensures the stable rotation of the adjusting rod 20. The first bevel gear 18 at the rear end of the adjusting rod 20 meshes with the second bevel gear 16 with a larger diameter to achieve deceleration. Increased torque allows the second bevel gear 16 to mesh with the meshing gear 17 for transmission. The meshing gear 17 slides through the toothed post 34 and the toothed post engagement groove 32 of the first threaded rod 31, driving the first threaded rod 31 to rotate. Simultaneously, the first mounting cylinder 27 and the second mounting cylinder 28 are fixed to the discharge cylinder 2 through the disassembly port 15. Inside, the first toothed plate 30 and the second toothed plate 38 on the outer surface of the first ball bearing 29 and the second ball bearing 36 slide and limit the movement with the first toothed groove 33 and the second toothed groove 39, respectively, ensuring the stable rotation of the first threaded rod 31 and the second threaded rod 35. Through the threaded connection with the threaded groove 40 of the adjusting baffle 22, the opening of the adjusting baffle 22 can be precisely adjusted. The transparent protective shell 7 on the left side of the discharge cylinder 2 allows for easy observation of the connecting seat 19. The scale on the front dial 24 and the pointer 25 on the adjusting rod 20 are matched to achieve quantitative adjustment. The first protective door 9 and the second protective door 10 on the left side, connected to the front protective frame 11 of the protective shell 7, can be opened and closed to facilitate the maintenance of internal transmission components and prevent impurities from entering. If liquid raw materials are added, in addition to adjusting the opening of the adjusting baffle 22, the liquid material quantity can also be adjusted through the liquid material quantity adaptation module. The throttling column 8 is fixed to the bottom inner wall of the discharge cylinder 2 by threads. According to the viscosity of the liquid raw material, the first blockage 44, the second blockage 23, and the third blockage 45 in the first throttling port 43, the second throttling port 42, and the third throttling port 41 can be engaged or disengaged to select the throttling port with the corresponding diameter to stabilize the flow rate. Throughout the feeding process, the feedback module monitors in real time, and the controller 5... 3. The electric telescopic rod 46 inside the bearing seat 5 is extended and retracted, driving the moving seat 4 to move back and forth. The limit frame 54 on the bearing seat 5 limits the moving seat 4, ensuring that the receiving cylinder 47 on the moving seat 4 accurately connects to the discharging cylinder 2. The receiving cylinder 47 is fixed by the limit ring 50 on the weighing plate 51. Four positioning rods 49 ensure the stability of the weighing plate 51. The pressure sensor 55 on the weighing pan 56 transmits the receiving weight signal to the controller 53. The timer 52 records the feeding time. The scale line 48 outside the receiving cylinder 47 assists in observation, realizing real-time feedback of the feeding amount. There is no need for frequent machine stop calibration, which solves the problems of low manual adjustment accuracy, no real-time feedback, and poor material state adaptability of existing equipment, and ensures accurate and stable feeding of boron trifluoride complex raw materials in different states.
