Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and more specifically, to a bidirectional rotating support type stirring through-shaft reaction vessel. Background Technology
[0002] In many fields such as chemical engineering and pharmaceuticals, reaction vessels are widely used as important equipment for carrying out chemical reactions. Traditional reaction vessel stirring systems usually adopt a unidirectional stirring method. In some complex chemical reaction processes, this stirring method has problems such as uneven stirring and poor material mixing, which affects the efficiency of the reaction and the quality of the product.
[0003] Furthermore, existing stirring shaft support structures are mostly unidirectional, which can easily lead to stirring shaft misalignment and accelerated wear after prolonged operation, reducing equipment lifespan and increasing maintenance costs. Therefore, a new type of reactor stirring system needs to be designed to improve stirring efficiency and equipment stability. Utility Model Content
[0004] In view of this, the present invention provides a bidirectional rotary support type stirring through-shaft reactor, which improves the stirring uniformity of materials in the reactor, enhances the stability of the stirring shaft, and extends the service life of the equipment through a unique bidirectional rotary support structure and synchronous rotation structure.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A bidirectional rotary support type stirred through-shaft reactor includes a vessel body, an outer cover, a drive device, a cover connecting shaft, a vessel body connecting shaft, a stirred through-shaft, and a stirring impeller. The vessel body has an open, sealed chamber at the top and support feet at the bottom. The outer cover is detachably connected to the vessel body and forms a sealed fit. The drive device is fixedly mounted below the vessel body. The cover connecting shaft is rotatably mounted at the center of the outer cover via a top bearing and is connected to the output end of the drive device. The vessel body connecting shaft is rotatably mounted at the center of the bottom of the vessel body via a bottom bearing. The stirred through-shaft vertically penetrates the sealed chamber, with its upper end coaxially connected to the cover connecting shaft and its lower end coaxially connected to the vessel body connecting shaft. The stirring impeller is fixedly mounted on the shaft of the stirred through-shaft. The cover connecting shaft, the stirred through-shaft, and the vessel body connecting shaft form a bidirectional rotary support structure.
[0007] By employing a bidirectional rotary support design for the cap connecting shaft, the stirring through shaft, and the vessel body connecting shaft, synchronous dynamic support of the stirring shaft is achieved at both ends of the vessel body, significantly enhancing the shaft system's anti-sway and anti-vibration performance. This structure, through the synergistic action of bearings at the top and bottom, effectively disperses the radial and axial combined loads generated during stirring, avoiding the premature bearing wear problem caused by torque concentration in traditional single-point supports. Furthermore, the through-type stirring shaft vertically penetrating the sealed chamber, combined with concentricity control through bidirectional support, ensures reliable sealing during the stirring of high-viscosity or particulate materials, making it particularly suitable for chemical reactions under high pressure or vacuum environments, reducing the risk of leakage due to shaft misalignment.
[0008] Preferably, a synchronous rotation structure is provided between the cap connecting shaft and the stirring through shaft, and between the vessel body connecting shaft and the stirring through shaft, so that the stirring through shaft rotates synchronously with the cap connecting shaft and the vessel body connecting shaft.
[0009] The synchronous rotation structure between the cap connecting shaft and the stirring through shaft, and between the vessel connecting shaft and the stirring through shaft, ensures that the rotational speed of each shaft segment is completely consistent through mechanical linkage, eliminating the phase difference problem caused by transmission clearance or assembly errors in traditional segmented stirring shafts. This design avoids torque fluctuations caused by asynchronous rotation, thereby improving power transmission efficiency and reducing the risk of wear on gears or couplings. This structure is particularly suitable for polymerization reactions or crystallization processes that require precise control of stirring speed, ensuring uniform mixing of materials in both the axial and radial directions, and improving product purity and reaction rate.
[0010] Preferably, the upper end of the stirring through shaft is provided with an upper threaded post and an upper sliding part. The upper threaded post is coaxially disposed at the center of the upper end of the stirring through shaft, and the upper sliding part is circumferentially distributed at the edge of the upper end of the stirring through shaft. The upper sliding part includes an upper groove, an upper sliding ball, an upper spring, and an upper cover. The upper groove is opened at the upper edge of the stirring through shaft, the upper sliding ball protrudes from the opening of the upper groove, and the upper spring is disposed between the bottom of the upper groove and the upper sliding ball. The upper cover is fixed to the opening of the upper groove by an upper screw, and its surface is provided with a limiting hole with a diameter smaller than that of the upper sliding ball.
[0011] The design of the upper threaded post and upper sliding part at the upper end of the stirring shaft, through the rigid fixation of the threaded joint and the elastic fit of the sliding ball, achieves axial micro-displacement compensation and dynamic load absorption. The elastic expansion and contraction characteristics of the upper sliding ball can adapt to the thermal expansion deformation or assembly tolerance of the cap connecting shaft, avoiding stress concentration caused by temperature changes. The limiting hole design combined with the spring buffer mechanism not only prevents the sliding ball from dislodging, but also absorbs the instantaneous impact load during high-speed stirring, reducing fatigue damage to the top bearing. It is especially suitable for frequent start-stop or variable speed conditions, extending the equipment maintenance cycle.
[0012] Preferably, the cap connecting shaft includes a top bearing and a top connecting main shaft. The top bearing is interference-fitted into the top opening of the outer cap. The top connecting main shaft has a T-shaped cross-section and includes a shaft body and a top extension platform. The lower surface of the top extension platform is provided with a top sliding groove corresponding to the upper sliding part. An elastically retractable top sliding ball is embedded in the top sliding groove. A top spring and a top cap are provided in the top sliding groove. The top spring is perpendicularly abutting against the bottom of the groove. The top cap is fixed to the groove opening by a top screw, and its surface is provided with a limiting hole with a diameter smaller than that of the top sliding ball.
[0013] The T-shaped cross-section design of the capping connecting shaft increases the contact area with the stirring shaft through the top extension platform, improving torque transmission efficiency. The elastic top sliding ball embedded in the top sliding groove forms multi-point elastic contact with the upper sliding part, adaptively adjusting the contact pressure during dynamic rotation to avoid localized wear caused by axial misalignment. The vertical abutment design of the top spring further disperses radial loads and reduces localized bearing stress, making it particularly suitable for stirring processes with frequent direction changes under high temperature and high pressure environments, ensuring smooth shaft operation and low noise characteristics.
[0014] Preferably, the lower end of the stirring shaft is provided with a lower threaded post and a lower sliding part. The lower threaded post is coaxially disposed at the center of the lower end of the stirring shaft, and the lower sliding part is circumferentially distributed at the edge of the lower end of the stirring shaft. The lower sliding part includes a lower groove, a lower sliding ball, a lower spring, and a lower cover. The lower groove is opened at the lower edge of the stirring shaft, the lower sliding ball protrudes from the opening of the lower groove, and the lower spring is disposed between the bottom of the lower groove and the lower sliding ball. The lower cover is fixed to the opening of the lower groove by a lower screw, and its surface is provided with a limiting hole with a diameter smaller than that of the lower sliding ball.
[0015] The threaded column at the lower end of the stirring shaft and the lower sliding part adopt a symmetrical design. The rigid fixing of the threads and the elastic engagement of the sliding ball compensate for minor displacements of the vessel body caused by thermal deformation or vibration. The buffering mechanism of the lower spring and sliding ball absorbs impact loads at the bottom of the stirring shaft, preventing premature fatigue failure of the bottom bearing due to rigid connection. The limiting hole design effectively isolates material from entering the sliding groove, avoiding jamming problems. It is especially suitable for stirring scenarios containing solid particles or high-viscosity materials, improving the durability of the equipment under complex operating conditions.
[0016] Preferably, the vessel body connecting shaft includes a bottom bearing and a bottom connecting main shaft. The bottom bearing is interference-fitted into the bottom opening of the vessel body. The bottom connecting main shaft has a T-shaped cross-section and includes a connecting part and a bottom extension platform. The upper surface of the bottom extension platform is provided with a bottom sliding groove corresponding to the lower sliding part. A bottom sliding ball that can elastically extend and retract is embedded in the bottom sliding groove. A bottom spring and a bottom cover are provided in the bottom sliding groove. The bottom spring is perpendicularly abutting against the bottom of the groove. The bottom cover is fixed to the groove opening by bottom screws, and its surface is provided with a limiting hole with a diameter smaller than that of the bottom sliding ball.
[0017] The bottom sliding groove of the vessel body connecting shaft and the bottom sliding ball form an elastic contact interface, and the bottom of the stirring shaft achieves self-alignment through the vertical support of the bottom spring. The T-shaped cross-section of the bottom connecting shaft enhances the bending stiffness of the shaft body and prevents bending deformation caused by stirring resistance. The design of the bottom cover and limiting hole effectively isolates external materials from entering the bearing cavity, ensuring a clean lubrication environment for the bottom bearing and reducing wear caused by particulate matter intrusion. It is particularly suitable for corrosive reaction systems or reaction systems containing solid-liquid mixtures, significantly improving the equipment's sealing performance and service life.
[0018] The advantages of this utility model compared to the prior art are:

[0074] The technical solutions in this application will now be described with reference to the accompanying drawings.
[0075] This embodiment provides a bidirectional rotary support type stirred through-shaft reactor, including a reactor body 100, an outer cover 200, a drive device 700, a cover connecting shaft 300, a reactor body connecting shaft 400, a stirred through-shaft 500, and a stirring impeller 600. The reactor body 100 has an open sealed chamber at the top and a support foot 120 at the bottom. The outer cover 200 is detachably connected to the reactor body 100 and forms a sealed fit. The drive device 700 is fixedly installed below the reactor body 100. The cover connecting shaft 300 is rotatable via a top bearing 310. The outer cover 200 is positioned at its center and connected to the output end of the drive unit 700; the vessel body connecting shaft 400 is rotatably mounted at the bottom center of the vessel body 100 via a bottom bearing 410; the stirring through shaft 500 vertically penetrates the sealed chamber, with its upper end coaxially connected to the cover connecting shaft 300 and its lower end coaxially connected to the vessel body connecting shaft 400; the stirring impeller 600 is fixedly mounted on the shaft body of the stirring through shaft 500; wherein, the cover connecting shaft 300, the stirring through shaft 500, and the vessel body connecting shaft 400 form a bidirectional rotational support structure. The drive unit 700 is fitted with an mounting sleeve 710, which is locked to the bottom of the vessel body 100 by screws.
[0076] The bidirectional rotary support design of the cap connecting shaft 300, the stirring through shaft 500, and the vessel body connecting shaft 400 achieves synchronous dynamic support for the stirring shaft at both ends of the vessel body 100, significantly enhancing the shaft system's anti-sway capability and vibration resistance. This structure, through the synergistic action of the bearings at the top and bottom, effectively disperses the radial and axial combined loads generated during stirring, avoiding the premature bearing wear problem caused by torque concentration in traditional single-point supports. Furthermore, the through-type stirring shaft vertically penetrating the sealed chamber, combined with the concentricity control of the bidirectional support, ensures reliable sealing during the stirring of high-viscosity or particulate materials, making it particularly suitable for chemical reactions under high pressure or vacuum environments, reducing the risk of leakage due to shaft misalignment.
[0077] In this embodiment, a synchronous rotation structure is provided between the cap connecting shaft 300 and the stirring through shaft 500, and between the vessel connecting shaft 400 and the stirring through shaft 500, so that the stirring through shaft 500 rotates synchronously with the cap connecting shaft 300 and the vessel connecting shaft 400.
[0078] The synchronous rotation structure between the cap connecting shaft 300 and the stirring through shaft 500, and between the vessel connecting shaft 400 and the stirring through shaft 500, ensures that the rotational speeds of each shaft segment are completely consistent through mechanical linkage, eliminating the phase difference problem caused by transmission clearance or assembly errors in traditional segmented stirring shafts. This design avoids torque fluctuations caused by asynchronous rotation, thereby improving power transmission efficiency and reducing the risk of wear on gears or couplings. This structure is particularly suitable for polymerization reactions or crystallization processes that require precise control of stirring speed, ensuring uniform mixing of materials in both the axial and radial directions, and improving product purity and reaction rate.
[0079] In this embodiment, the upper end of the stirring through shaft 500 is provided with an upper threaded post 510 and an upper sliding part 520. The upper threaded post 510 is coaxially disposed at the center of the upper end of the stirring through shaft 500, and the upper sliding part 520 is circumferentially distributed at the edge of the upper end of the stirring through shaft 500. The upper sliding part 520 includes an upper groove 525, an upper sliding ball 521, an upper spring 523, and an upper cover 522. The upper groove 525 is opened at the upper edge of the stirring through shaft 500, the upper sliding ball 521 partially protrudes from the opening of the upper groove 525, and the upper spring 523 is disposed between the bottom of the upper groove 525 and the upper sliding ball 521. The upper cover 522 is fixed to the opening of the upper groove 525 by an upper screw 524, and its surface is provided with a limiting hole with a diameter smaller than that of the upper sliding ball 521.
[0080] The design of the upper threaded post 510 and the upper sliding part 520 at the upper end of the stirring shaft 500, through the rigid fixation of the threaded coaxiality and the elastic cooperation of the sliding ball, achieves axial micro-displacement compensation and dynamic load absorption. The elastic expansion and contraction characteristics of the upper sliding ball 521 can adapt to the thermal expansion deformation or assembly tolerance of the cap connecting shaft 300, avoiding stress concentration caused by temperature changes. The limiting hole design combined with the spring buffer mechanism not only prevents the sliding ball from falling out, but also absorbs the instantaneous impact load during high-speed stirring, reducing fatigue damage to the top bearing 310. It is especially suitable for frequent start-stop or variable speed conditions, extending the equipment maintenance cycle.
[0081] In this embodiment, the cap connecting shaft 300 includes a top bearing 310 and a top connecting main shaft 320. The top bearing 310 is interference-fitted into the top opening 210 of the outer cap 200. The top connecting main shaft 320 has a T-shaped cross-section and includes a shaft body and a top extension platform 321. The lower surface of the top extension platform 321 is provided with a top sliding groove 335 corresponding to the upper sliding part 520. A top sliding ball 331 that can elastically extend and retract is embedded in the top sliding groove 335. A top spring 333 and a top cap 332 are provided in the top sliding groove 335. The top spring 333 abuts vertically against the bottom of the groove. The top cap 332 is fixed to the groove opening by a top screw 334, and its surface is provided with a limiting hole with a diameter smaller than that of the top sliding ball 331.
[0082] The T-shaped cross-section design of the capping connecting shaft 300 increases the contact area with the stirring through shaft 500 through the top extension platform 321, improving torque transmission efficiency. The elastic top sliding ball 331 embedded in the top sliding groove 335 forms multi-point elastic contact with the upper sliding part 520, adaptively adjusting the contact pressure during dynamic rotation to avoid local wear caused by axial misalignment. The vertical abutment design of the top spring 333 further disperses the radial load and reduces local stress on the bearing, making it particularly suitable for stirring processes with frequent direction changes under high temperature and high pressure environments, ensuring smooth shaft operation and low noise characteristics.
[0083] In this embodiment, the lower end of the stirring through shaft 500 is provided with a lower threaded post 530 and a lower sliding part 540. The lower threaded post 530 is coaxially disposed at the center of the lower end of the stirring through shaft 500, and the lower sliding part 540 is circumferentially distributed at the edge of the lower end of the stirring through shaft 500. The lower sliding part 540 includes a lower groove 545, a lower sliding ball 541, a lower spring 543, and a lower cover 542. The lower groove 545 is opened at the lower edge of the stirring through shaft 500, the lower sliding ball 541 partially protrudes from the opening of the lower groove 545, and the lower spring 543 is disposed between the bottom of the lower groove 545 and the lower sliding ball 541. The lower cover 542 is fixed to the opening of the lower groove 545 by a lower screw 544, and its surface is provided with a limiting hole with a diameter smaller than that of the lower sliding ball 541.
[0084] The threaded post 530 and the lower sliding part 540 at the lower end of the stirring shaft 500 are symmetrically designed. Through rigid thread fixing and elastic engagement of the sliding ball, they compensate for minor displacements of the vessel body 100 caused by thermal deformation or vibration. The buffering mechanism of the lower spring 543 and the sliding ball 541 absorbs impact loads at the bottom of the stirring shaft, preventing premature fatigue failure of the bottom bearing 410 due to rigid connection. The limiting hole design effectively isolates material from entering the sliding groove, avoiding jamming problems. It is especially suitable for stirring scenarios containing solid particles or high-viscosity materials, improving the durability of the equipment under complex operating conditions.
[0085] In this embodiment, the vessel body connecting shaft 400 includes a bottom bearing 410 and a bottom connecting main shaft 420. The bottom bearing 410 is interference-fitted into the bottom opening 110 of the vessel body 100. The bottom connecting main shaft 420 has a T-shaped cross-section and includes a connecting part and a bottom extension platform 421. The upper surface of the bottom extension platform 421 is provided with a bottom sliding groove 425 corresponding to the lower sliding part 540.

[0086] The bottom sliding groove 425 of the vessel body connecting shaft 400 forms an elastic contact interface with the bottom sliding ball 431, and the bottom of the stirring shaft achieves self-alignment of the bottom through the vertical support of the bottom spring 423. The T-shaped cross-section of the bottom connecting main shaft 420 enhances the bending stiffness of the shaft body and prevents bending deformation of the shaft body due to stirring resistance. The design of the bottom cover 422 and the limiting hole effectively isolates external materials from entering the bearing cavity, ensuring a clean lubrication environment for the bottom bearing 410, reducing wear caused by particulate matter intrusion, and is particularly suitable for corrosive reaction systems or reaction systems containing solid-liquid mixtures, significantly improving the equipment's sealing performance and service life.
