Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a multifunctional composite reaction vessel. Background Technology

[0002] A reaction vessel is a device used to stir materials. It uses a motor to drive the stirring device to rotate, so that the materials are fully mixed inside the vessel. Reactors usually have heating or cooling functions to meet the reaction conditions of different materials. They are made of various materials and can be selected according to the characteristics of the materials. Reactors are widely used in chemical, pharmaceutical and food industries.

[0003] Reactors can effectively improve material mixing efficiency and ensure product quality uniformity, but they still have certain problems: 1) Traditional stirring paddles have insufficient torque at low speeds and excessive energy consumption at high speeds; 2) Conventional adjustable paddles require external hydraulic / electric control, which is complex in structure, costly, and difficult to maintain. Therefore, in view of the above situation, there is an urgent need to develop a multifunctional composite reactor to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional composite reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional composite reactor, comprising a reactor body, a reactor cover installed on the reactor body for sealing, a stirring paddle mechanism located inside the reactor body for stirring materials, a base installed on the reactor cover, and a motor installed on the base for driving the stirring paddle mechanism to rotate;

[0006] The stirring mechanism includes a rotating shaft, stirring blades and blades. The rotating shaft is rotatably mounted inside the vessel. Several sets of stirring blades are horizontally arranged on the rotating shaft, and the blades are mounted on the rotating shaft through the stirring blades.

[0007] The rotating shaft is fitted with several mounting tubes, and several guide keyways are provided in opposite directions inside the mounting tubes;

[0008] The agitator assembly includes a main shaft, a mounting shaft, end cover a, a transmission component, a spring, a top plate, an adjusting bolt, and end cover b. One end of the main shaft is rotatably mounted on one end of the mounting tube via end cover a, and the mounting shaft is fixed to the other end of the main shaft. The transmission component, spring, and top plate are sequentially embedded in the mounting tube, and the adjusting bolt is rotatably mounted on the other end of the mounting tube via end cover b.

[0009] In practical use, the material fluid dynamics are used to achieve self-adjustment of the blade angle. At low speeds, the fluid resistance is small, and the spring keeps the blade at a large tilt angle to provide high torque mixing. At high speeds, the fluid resistance increases, and the spring force is overcome to reduce the blade tilt angle to achieve high shear crushing. Thus, efficient mixing and crushing multi-functional operation are achieved in a single device, improving the adaptability and energy efficiency of the reactor, while reducing external control requirements and optimizing energy consumption.

[0010] Preferably, a pressure manhole, a feed inlet, a sight glass, and a breather are sequentially installed on the vessel lid.

[0011] Preferably, a base is fixed to the bottom of the vessel.

[0012] Preferably, the spindle has a ramp a at one end inside the mounting tube, and the transmission component has a ramp b at the end adjacent to the spindle. Ramps a and ramp b are slidably fitted together, and the outer wall of the transmission component is fixed with a guide key a that is slidably fitted with the guide keyway.

[0013] In practical use, the sliding fit between the inclined platform a at the end of the main shaft and the inclined platform b on the transmission component, combined with the constraint of the guide key a on the outer wall of the transmission component and the guide keyway inside the mounting tube, accurately converts the rotational resistance of the blade into axial thrust, making the tilt angle self-adjustment process driven by hydrodynamics smoother and more reliable, while ensuring the stability of torque transmission, and significantly improving the response accuracy and mechanical durability of switching between high and low speed conditions.

[0014] Preferably, the outer wall of the spindle is fixed with a shoulder that matches the end cover a, the outer wall of the spindle is detachably mounted with a limit block, and the outer wall of the end cover a is provided with a number of positioning grooves distributed in a ring along the axial direction, and positioning bolts are detachably mounted in the positioning grooves.

[0015] In practical use, the axial positioning of the spindle shoulder and end cover a, combined with the synergistic constraint of the detachable limiting block and the annularly distributed positioning grooves of end cover a, ensures the spindle's rotational freedom while achieving precise axial positioning. Furthermore, the adjustable fixing of the positioning bolts in the positioning grooves allows for multiple adjustable positions of the initial tilt angle of the blades, significantly improving the equipment's adaptability to different materials and ease of maintenance.

[0016] Preferably, the inner wall of the top plate is provided with an internal thread that matches the adjusting bolt, and the outer wall of the top plate is fixed with a guide key b that slides in conjunction with the guide keyway.

[0017] In practical use, the internal thread of the top plate and the thread of the adjusting bolt are engaged, and the sliding constraint of the guide key b on the outer wall and the guide keyway of the installation pipe is combined to achieve a precise conversion of rotary motion to linear motion: when the adjusting bolt is rotated, the top plate compresses or releases the spring along the axis, thereby steplessly adjusting the spring preload, providing a customizable initial load for the blade tilt angle self-adjustment system, and significantly enhancing the equipment's adaptability to different fluid resistance conditions and the accuracy of process control.

[0018] Preferably, the base is connected to the motor drive, and the rotating shaft is coaxially mounted with the output shaft of the base.

[0019] In practical use, the direct drive connection between the base and the motor, along with the coaxial installation of the rotating shaft and the output shaft of the base, forms a rigid power transmission chain, which significantly improves torque transmission efficiency. At the same time, it ensures that the rotating shaft of the stirring paddle mechanism maintains dynamic balance under high-speed / high-load conditions, suppresses vibration deviation from the source, and ensures the accurate response of the fluid dynamic self-regulating system and the stability of the equipment during long-term operation.

[0020] Preferably, the transmission component and the top plate are slidably connected to the mounting tube, and the main shaft, transmission component, top plate, and adjusting bolts are coaxially arranged.

[0021] In practical use, this coaxial design, through the sliding connection constraint between the transmission components and the top plate and the mounting tube, combined with the precise coaxial setting of the main shaft, transmission components, top plate, and adjusting bolts, constructs a linear power transmission chain without radial offset. This allows the axial thrust converted from the fluid resistance by the inclined platform a / inclined platform b to be efficiently transmitted to the spring along a single axis, eliminating the risk of uneven wear and reducing transmission energy consumption. At the same time, it ensures that the blade tilt angle adjustment process is free from jamming, significantly improving the sensitivity and mechanical life of the self-adjusting system.

[0022] Compared with the prior art, this utility model provides a multifunctional composite reactor with the following advantages:

[0023] Through a hydrodynamic adaptive blade tilt angle adjustment mechanism, a large tilt angle is maintained at low speeds to achieve powerful mixing, while the tilt angle is automatically reduced at high speeds to achieve efficient crushing. At the same time, the stepless adjustment of spring preload and the multi-level setting of blade initial tilt angle flexibly match different material characteristics. Combined with a coaxial rigid transmission chain to eliminate energy loss, and a detachable structure to achieve tool-free maintenance, a single device can perform both mixing and crushing functions, significantly reducing energy consumption and breaking through the limitations of traditional reactors that fix process parameters, greatly improving production adaptability and operating economy.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] Example:

[0038] Please see Figures 1-9 This utility model provides a technical solution: a multifunctional composite reactor, including a reactor body 10, a reactor cover 20 installed on the reactor body 10 for sealing, a stirring paddle mechanism 50 located inside the reactor body 10 for stirring materials, a base 30 installed on the reactor cover 20, and a motor 40 installed on the base 30 for driving the stirring paddle mechanism 50 to rotate.

[0039] The stirring mechanism 50 includes a rotating shaft 510, a stirring assembly 520, and a blade 530. The rotating shaft 510 is rotatably installed inside the vessel body 10. Several sets of stirring assemblies 520 are horizontally arranged on the rotating shaft 510, and the blade 530 is installed on the rotating shaft 510 through the stirring assembly 520.

[0040] The rotating shaft 510 is provided with several mounting tubes 511, and several guide keyways 512 are provided in opposite directions inside the mounting tubes 511.

[0041] The agitator assembly 520 includes a main shaft 521, a mounting shaft 522, an end cover a 523, a transmission component 524, a spring 525, a top plate 526, an adjusting bolt 527, and an end cover b 528. One end of the main shaft 521 is rotatably mounted on one end of the mounting tube 511 via the end cover a 523. The mounting shaft 522 is fixed to the other end of the main shaft 521. The transmission component 524, the spring 525, and the top plate 526 are sequentially embedded in the mounting tube 511. The adjusting bolt 527 is rotatably mounted on the other end of the mounting tube 511 via the end cover b 528.

[0042] In practical use, the material fluid dynamics are used to achieve self-adjustment of the blade 530 angle. At low speeds, the fluid resistance is small, and the spring 525 keeps the blade 530 at a large tilt angle to provide high torque mixing. At high speeds, the fluid resistance increases, and the force of the spring 525 is overcome to reduce the tilt angle of the blade 530 to achieve high shear crushing. Thus, efficient mixing and crushing multi-functional operation are achieved in a single device, improving the adaptability and energy efficiency of the reactor, while reducing external control requirements and optimizing energy consumption.

[0043] Preferably, a pressure manhole 210, a feed inlet 220, a sight glass 230, and a breather 240 are sequentially installed on the vessel lid 20.

[0044] Preferably, a base 110 is fixed to the bottom of the vessel body 10.

[0045] Preferably, the main shaft 521 has a ramp a5211 at one end inside the mounting tube 511, and the transmission component 524 has a ramp b5241 at one end adjacent to the main shaft 521. The ramp a5211 and the ramp b5241 are slidably engaged, and the outer wall of the transmission component 524 is fixed with a guide key a5242 that is slidably engaged with the guide keyway 512.

[0046] In practical use, the sliding engagement between the inclined platform a5211 at the end of the main shaft 521 and the inclined platform b5241 on the transmission component 524, combined with the constraint of the guide key a5242 on the outer wall of the transmission component 524 and the guide keyway 512 inside the mounting tube 511, accurately converts the rotational resistance of the blade 530 into axial thrust, making the tilt angle self-adjustment process driven by hydrodynamics smoother and more reliable, while ensuring the stability of torque transmission, and significantly improving the response accuracy and mechanical durability of switching between high and low speed conditions.

[0047] Preferably, the outer wall of the spindle 521 is fixed with a shoulder 5212 that is compatible with the end cover a523, the outer wall of the spindle 521 is detachably installed with a limit block 5213, and the outer wall of the end cover a523 is provided with a plurality of positioning grooves 5231 distributed in an axial direction, and positioning bolts 5232 are detachably installed in the positioning grooves 5231.

[0048] In practical use, the axial positioning of the main shaft 521's shoulder 5212 and the end cover a523, combined with the synergistic constraint of the detachable limiting block 5213 and the annularly distributed positioning grooves 5231 of the end cover a523, ensures the rotational freedom of the main shaft 521 while achieving precise axial positioning. Furthermore, the adjustable fixing of the positioning bolts 5232 in the positioning grooves 5231 allows the initial tilt angle of the blade 530 to have multiple adjustable positions, significantly improving the equipment's process adaptability to different materials and ease of maintenance.

[0049] Preferably, the inner wall of the top plate 526 is provided with an internal thread 5261 that is compatible with the adjusting bolt 527, and the outer wall of the top plate 526 is fixed with a guide key b5262 that slides with the guide keyway 512.

[0050] In practical use, the internal thread 5261 of the top plate 526 and the threaded engagement of the adjusting bolt 527, combined with the sliding constraint of the guide key b5262 on the outer wall and the guide keyway 512 of the mounting pipe 511, achieve a precise conversion from rotary motion to linear motion. When the adjusting bolt 527 is rotated, the top plate 526 compresses or releases the spring 525 axially, thereby steplessly adjusting the spring preload and providing a customizable initial load for the blade 530 tilt angle self-adjustment system, significantly enhancing the equipment's adaptability to different fluid resistance conditions and the precision of process control.

[0051] Preferably, the base 30 is driven by the motor 40, and the rotating shaft 510 is coaxially mounted with the output shaft of the base 30.

[0052] In practical use, the direct drive connection between the base 30 and the motor 40, along with the coaxial installation of the rotating shaft 510 and the output shaft of the base 30, forms a rigid power transmission chain, which significantly improves torque transmission efficiency. At the same time, it ensures that the rotating shaft 510 of the stirring paddle mechanism 50 maintains dynamic balance under high-speed / high-load conditions, suppresses vibration deviation from the source, and ensures the accurate response of the fluid dynamic self-regulation system and the stability of the equipment during long-term operation.

[0053] Preferably, the transmission component 524 and the top plate 526 are slidably connected to the mounting tube 511, and the main shaft 521, transmission component 524, top plate 526, and adjusting bolt 527 are coaxially arranged.

[0054] In practical use, this coaxial design, through the sliding connection constraint between the transmission component 524 and the top plate 526 and the mounting tube 511, combined with the precise coaxial setting of the main shaft 521, transmission component 524, top plate 526, and adjusting bolt 527, constructs a linear power transmission chain without radial offset. This allows the axial thrust converted from fluid resistance by inclined platform a5211 / inclined platform b5241 to be efficiently transmitted to the spring 525 along a single axis, eliminating the risk of uneven wear and reducing transmission energy consumption. At the same time, it ensures that the blade 530 tilt angle adjustment process is free from jamming, significantly improving the sensitivity and mechanical life of the self-adjusting system.

[0055] Working principle: When the motor 40 drives the rotating shaft 510 to rotate, the impeller 530 fixed to the mounting shaft 522 rotates with the main shaft 521. During low-speed mixing, the fluid resistance of the material is small. The spring 525, in conjunction with the top plate 526, causes the transmission component 524 to move axially toward the main shaft 521 and apply pressure. The inclined platform b5241 of the transmission component 524 slides along the inclined platform a5211 of the main shaft 521, converting the axial thrust into the radial deflection of the main shaft 521, forcing the impeller 530 to maintain a large tilt angle to achieve high torque mixing. During high-speed rotation, the fluid resistance increases dramatically, and the resistance torque is transmitted to the main shaft through the mounting shaft 522. 521, the inclined platform a5211 generates a reverse axial thrust on the inclined platform b5241, which overcomes the preload of the spring 525 and pushes the transmission component 524 backward toward the top plate 526, thereby compressing the spring 525, reducing the radial deflection angle of the main shaft 521, and the blade 530 automatically switches to a small tilt angle state to complete high shear crushing; by rotating the adjusting bolt 527, the position of the top plate 526 is changed to steplessly adjust the preload of the spring 525, and the positioning slot 5231 of the limit block 5213 and the positioning bolt 5232 can preset the initial tilt angle of the blade 530 to achieve adaptive process control.
