Description

Technical Field

[0001] This utility model relates to the field of reactor technology, and more specifically, to a dynamic continuous reactor with a stirring shaft structure. Background Technology

[0002] A reactor is a device for realizing a reaction process and is widely used in chemical, oil refining, metallurgical, and light industries. For example, the reactor proposed in application number "CN201910067751.8" includes: a tank having a reaction chamber with a raw liquid inlet, a liquid outlet, a circulating liquid inlet, and a circulating liquid outlet. The opening direction of the raw liquid inlet is tangential to the circumference of the tank, and the liquid outlet is located above the raw liquid inlet; and a rectifier disposed in the reaction chamber, located below the liquid outlet and above the raw liquid inlet. The rectifier is configured to block the rising of the raw liquid swirling in through the raw liquid inlet and guide a portion of the circulating liquid flowing in through the circulating liquid inlet to descend while another portion rises.

[0003] However, in the above-mentioned technical solutions, the reactor mainly relies on the impact force of the raw liquid entering tangentially along the circumference and the guiding effect of the rectifier on the fluid to achieve material mixing. It lacks an active stirring structure. When processing high-viscosity materials or materials containing solid particles, it is easy to cause uneven material mixing and solid particle sedimentation and accumulation, resulting in incomplete reaction. At the same time, it does not have a heat exchange channel synchronized with the material stirring process, so the heat generated or the required heat of reaction during the reaction is difficult to transfer efficiently, resulting in low heat exchange efficiency, which in turn affects the overall reaction rate and effect. Therefore, we propose a dynamic continuous reactor with a stirring shaft structure to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a dynamic continuous reactor with a stirring shaft structure. This solves the problem that the reactor mainly relies on the impact force of the raw liquid entering tangentially along the circumference and the guiding effect of the rectifier on the fluid to achieve material mixing. It lacks an active stirring structure, which easily leads to uneven material mixing and solid particle sedimentation and accumulation when processing high-viscosity materials or materials containing solid particles, resulting in incomplete reaction. At the same time, it does not have a heat exchange channel synchronized with the material stirring process, making it difficult to efficiently transfer the heat generated or required for the reaction, resulting in low heat exchange efficiency, which in turn affects the overall reaction rate and effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dynamic continuous reactor with a stirring shaft structure includes a reaction vessel. A sealing cover is fitted onto the upper end of the reaction vessel. A stirring mechanism is installed between the sealing cover and the reaction vessel. A feed pipe is installed through the upper side of one side of the reaction vessel, and a discharge pipe is installed through the lower side of the interior of the reaction vessel. The stirring mechanism includes a rotating shaft that is movably installed inside the reaction vessel. Several stirring rods are installed on the outer side of the shaft inside the reaction vessel. An auxiliary rod is movably installed inside the sealing cover. The lower end of the auxiliary rod is engaged with the rotating shaft. A connecting groove is provided through the interior of the auxiliary rod, the rotating shaft, and the stirring rods. A first gear is installed on the lower end of the shaft. A motor is installed on the lower surface of the reaction vessel. A second gear is installed on the output end of the motor. The second gear meshes with the first gear. Flanges are installed on the outer sides of the reaction vessel and the sealing cover, respectively, and the flanges are connected by bolts.

[0007] Preferably, partition plates are installed inside the connecting groove located between the stirring rod and the rotating shaft.

[0008] Preferably, temporary storage boxes are installed on the opposite sides of the reaction vessel and the sealing cap, and the opposite ends of the rotating shaft and the auxiliary rod are respectively connected to the temporary storage boxes.

[0009] Preferably, the temporary storage boxes are equipped with annular sliders on their sides that are close to each other, and the annular sliders are respectively engaged inside the rotating shaft and the auxiliary rod. Connecting pipes are respectively installed on the sides of the temporary storage boxes that are far apart from each other.

[0010] Preferably, annular sealing blocks are installed at both the inner and outer ends of the lower surface of the auxiliary rod, and annular sealing grooves are provided at both the inner and outer ends of the upper surface of the rotating shaft, with the annular sealing blocks respectively engaging and installed inside the annular sealing grooves.

[0011] Preferably, a plurality of positioning rods are installed on the lower surface of the auxiliary rod and at one end between the annular sealing blocks, and a plurality of positioning holes are provided on the upper surface of the rotating shaft and at one end between the annular sealing grooves, and the positioning rods are respectively engaged and installed inside the positioning holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, a connecting groove is provided through the auxiliary rod, the rotating shaft, and the stirring rod, and a partition plate is installed in the connecting groove between the stirring rod and the rotating shaft. This allows the liquid or gas medium to flow along the connecting groove and the partition plate. During the rotation of the rotating shaft and the stirring rod, the medium and the reactants come into contact synchronously, realizing the synergistic effect of stirring and heat exchange. The heat exchange medium can directly penetrate into the interior of the material along with the stirring components, greatly improving the heat transfer efficiency, ensuring precise temperature control during the reaction process, and thus improving the reaction rate and effect.

[0014] (2) In this utility model, a stirring mechanism driven by a motor is set up. The motor drives the second gear to mesh with the first gear, thereby driving the rotating shaft and stirring rod to rotate, forming an active stirring structure. This effectively solves the problems of uneven mixing of high-viscosity materials and sedimentation of solid particles. Through the continuous rotation of the stirring rod, the material can be fully dispersed and mixed to ensure that the reaction is fully carried out, which significantly improves the adaptability to complex materials.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 9 As shown in the figure, this utility model embodiment proposes a dynamic continuous reactor with a stirring shaft structure, including a reaction tank 1. A sealing cover 2 is fitted onto the upper end of the reaction tank 1. A stirring mechanism 4 is installed between the sealing cover 2 and the reaction tank 1. A feed pipe 5 is installed through the upper end of one side of the reaction tank 1, and a discharge pipe 6 is installed through the lower end of the interior of the reaction tank 1. The stirring mechanism 4 includes a rotating shaft 401, which is movably installed inside the reaction tank 1. Several stirring rods 402 are installed on the outer side of the shaft 401 inside the reaction tank 1. The interior of the sealing cover 2 is movably connected to the rotating shaft 401. An auxiliary rod 408 is installed, and its lower end is engaged with the rotating shaft 401. A connecting groove 403 is provided through the interior of the auxiliary rod 408, the rotating shaft 401, and the stirring rod 402. A first gear 413 is installed at the lower end of the shaft 401. A motor 415 is installed on the lower surface of the reaction vessel 1. A second gear 414 is installed at the output end of the motor 415. The second gear 414 is meshed with the first gear 413. Flanges 3 are installed on the outer sides of the reaction vessel 1 and the sealing cover 2, respectively, and the flanges 3 are connected by bolts.

[0027] like Figures 4 to 9As shown, in another embodiment of this utility model, a partition plate 404 is installed inside the connecting groove 403 between the stirring rod 402 and the rotating shaft 401. A temporary storage box 405 is installed on the side of the reaction vessel 1 and the sealing cover 2 that are far apart from each other. The ends of the rotating shaft 401 and the auxiliary rod 408 that are far apart from each other are respectively connected to the temporary storage box 405. Annular sliders 407 are installed on the side of the temporary storage box 405 that are close to each other. The annular sliders 407 are respectively engaged inside the rotating shaft 401 and the auxiliary rod 408. The ends of the temporary storage box 405 that are far apart from each other are respectively connected to the temporary storage box 405. A connecting pipe 406 is installed. Annular sealing blocks 409 are installed at both the inner and outer ends of the lower surface of the auxiliary rod 408. Annular sealing grooves 410 are provided at both the inner and outer ends of the upper surface of the rotating shaft 401. The annular sealing blocks 409 are respectively engaged and installed inside the annular sealing grooves 410. Several positioning rods 411 are installed at one end of the lower surface of the auxiliary rod 408 located between the annular sealing blocks 409. Several positioning holes 412 are provided at one end of the upper surface of the rotating shaft 401 located between the annular sealing grooves 410. The positioning rods 411 are respectively engaged and installed inside the positioning holes 412.

[0028] The sealing cover 2 is connected to the reaction vessel 1 by the flange 3 and fixed with bolts to ensure that a sealed space is formed inside the reaction vessel 1; the annular sealing block 409 at the lower end of the auxiliary rod 408 is inserted into the annular sealing groove 410 of the rotating shaft 401, and the positioning rod 411 is inserted into the positioning hole 412 to achieve a precise sealing connection between the auxiliary rod 408 and the rotating shaft 401.

[0029] When the material needs to be reacted, the material to be reacted is added into the reaction tank 1 through the feed pipe 5. Then, the motor 415 is started, which drives the second gear 414 to rotate. The second gear 414 meshes with the first gear 413 to drive the rotating shaft 401 and the stirring rod 402 to rotate synchronously and stir the material. Then, the heat exchange medium is introduced through the connecting pipe 406 on the temporary storage tank 405. The medium then enters the connecting groove 403 inside the auxiliary rod 408, the rotating shaft 401 and the stirring rod 402 through the temporary storage tank 405. Under the guidance of the partition plate 404, it flows along the connecting groove 403 and finally exits from the connecting pipe 406 of the temporary storage tank 405 at the other end, forming a cycle. This ensures that the material is fully mixed under the action of the stirring rod 402 during the stirring process. At the same time, the heat exchange medium exchanges heat with the material through the connecting groove 403. Finally, after the reaction is completed, the material is discharged through the discharge pipe 6.

[0030] The engagement of the annular sealing block 409 and the annular sealing groove 410 prevents leakage of the heat exchange medium in the connecting groove 403 and ensures the sealing of the reaction environment; the positioning rod 411 and the positioning hole 412 ensure that the auxiliary rod 408 and the rotating shaft 401 rotate coaxially, reducing mechanical wear and extending the equipment life.

[0031] The cooperation between the temporary storage box 405 and the annular slider 407 ensures that the heat exchange medium is stably introduced into the connecting groove 403 when the rotating shaft 401 and the auxiliary rod 408 rotate, without affecting the rotation of the stirring mechanism 4. Then, the connecting groove 403 passes through the stirring rod 402 and the rotating shaft 401, so that the heat exchange medium penetrates into the material along with the stirring components. Combined with the guidance of the medium flow direction by the partition plate 404, the heat exchange area is increased and the heat transfer efficiency is improved.

[0032] The working principle of this type of dynamic continuous reactor with a stirring shaft structure:

[0033] In use, when the material needs to be reacted, the material to be reacted is first added to the reaction tank 1 through the feed pipe 5. Then, the motor 415 is started, which drives the second gear 414 to rotate. The second gear 414 meshes with the first gear 413 to drive the rotating shaft 401 and the stirring rod 402 to rotate synchronously and stir the material. Then, the heat exchange medium is introduced through the connecting pipe 406 on the temporary storage tank 405. The medium then enters the connecting groove 403 inside the auxiliary rod 408, the rotating shaft 401 and the stirring rod 402 through the temporary storage tank 405. Under the guidance of the partition plate 404, it flows along the connecting groove 403 and finally exits from the connecting pipe 406 of the temporary storage tank 405 at the other end, forming a cycle. This ensures that the material is fully mixed under the action of the stirring rod 402 during the stirring process. At the same time, the heat exchange medium exchanges heat with the material through the connecting groove 403. Finally, after the reaction is completed, the material is discharged through the discharge pipe 6.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
