Description

Technical Field

[0001] This utility model relates to the field of magnetic coupling stirring technology, and in particular to a sealed magnetic coupling stirring device. Background Technology

[0002] In modern chemical, pharmaceutical, and food processing industries, stirring devices are key equipment, and their performance and efficiency directly affect the stability of the production process and product quality. Sealed magnetic coupling stirring devices, as a leak-free, safe and reliable stirring technology, are widely used in various reaction vessels and storage tanks. However, traditional sealed magnetic coupling stirring devices have some structural shortcomings.

[0003] The disassembly and installation of the agitator is an important part of daily maintenance and cleaning. In traditional equipment, the agitator is usually connected to the magnetic coupler through a complex connection mechanism. This not only increases the difficulty of installation, but also limits the quick replacement and cleaning of the agitator. Secondly, traditional equipment often exhibits problems of uneven mixing and low efficiency when mixing high-viscosity materials or in situations requiring efficient mixing. This not only prolongs the production cycle, but may also affect the uniformity and quality stability of the final product. Summary of the Invention

[0004] The present invention proposes a sealed magnetic coupling stirring device, which solves the problems of inconvenient maintenance and cleaning, as well as low stirring efficiency of existing sealed magnetic coupling stirring devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sealed magnetic coupling stirring device includes a reaction vessel. A protective cover is bolted to the top of the reaction vessel, and a limit ring is provided inside the protective cover at one end. Two sets of support plates are fixedly connected to the upper part of the reaction vessel, and a detachable sealing plate is provided below the support plates. An installation groove is provided at the lower part of the reaction vessel, and two sets of rotating shafts are provided inside the support plates and the installation groove. A stirring mechanism is provided outside the rotating shafts.

[0007] The stirring mechanism includes an inner magnetic rotor and an outer magnetic rotor. The outer magnetic rotor is located above the inside of the limiting ring, and the corresponding inner magnetic rotor is located below the inside of the limiting ring. The inner magnetic rotor and the outer magnetic rotor attract each other through magnetic force and maintain synchronous rotation, thereby driving the rotating shaft to stir the inside of the reaction vessel.

[0008] Preferably, a feeding hopper is installed inside the protective cover on the side of the limiting ring at the other end, and a sliding groove is provided inside the upper part of the feeding hopper, and a matching sliding cover is provided inside the sliding groove for sliding connection.

[0009] Preferably, a speed reducer is provided at the top of the limiting ring, and the output end of the speed reducer is fixedly connected to the external magnetic rotor, and the top of the speed reducer is fixedly connected to the drive motor.

[0010] Preferably, the reactor has a movable groove located below the support plate inside, and one end of the movable groove extends to the outside of the reactor. The movable groove matches the sealing plate, and an elastic pad is fixedly connected to the side end of the sealing plate. The elastic pad is installed on the outside of the reactor by a threaded knob.

[0011] Preferably, the support plate and the mounting groove are provided with bearings, and the rotating shaft is installed inside the bearings. A guide sleeve is provided above the mounting groove on the outside of the rotating shaft. A discharge pipe is provided inside the lower part of the reactor. A knob valve is provided on the outside of the discharge pipe. A support frame is provided at the bottom of the reactor.

[0012] Preferably, the stirring mechanism further includes a driving synchronizing wheel, a driven synchronizing wheel, a synchronizing belt, and stirring blades, and an inner magnetic rotor is fixedly connected to the top of one end of the rotating shaft, with a driving synchronizing wheel disposed below the inner magnetic rotor on the outside of the rotating shaft.

[0013] Preferably, a driven synchronous pulley is fixedly connected to the outer side of the other end of the rotating shaft, and the driving synchronous pulley and the driven synchronous pulley are connected by a synchronous belt drive. Multiple sets of stirring blades are provided on the outer side of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This sealed magnetic coupling stirring device has a protective cover bolted to the top of the reactor. The cover can be removed by bolting, and the sealing plate can be taken out from the movable groove by turning the threaded knob. The quick-release connection structure facilitates cleaning of the inside of the reactor, which helps to improve maintenance efficiency. At the same time, it also allows users to flexibly replace the stirring blades according to process requirements, enhancing the versatility and flexibility of the equipment.

[0016] The support plate and mounting groove are equipped with two sets of rotating shafts, expanding the single rotating shaft into a dual-shaft structure. Different shapes and sizes of stirring blades are installed on each shaft, and they are connected by a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt drive. This design not only increases the stirring area, but also forms a more complex flow field through the interaction of different stirring blades, which can effectively improve stirring efficiency and mixing uniformity. At the same time, the inner magnetic rotor and the outer magnetic rotor adopt a magnetic coupling method, and there is no physical contact between the inner magnetic rotor and the outer magnetic rotor, which further ensures the sealing of the reactor.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figures 1-5 This utility model provides a technical solution: a sealed magnetic coupling stirring device, including a reaction vessel 1, a protective cover 3 is installed on the top of the reaction vessel 1 by bolts 2, and a limit ring 4 is provided inside the protective cover 3 at one end, two sets of support plates 6 are fixedly connected to the upper part of the inside of the reaction vessel 1, and a detachable sealing plate 5 is provided below the support plate 6, and an installation groove 7 is provided at the lower part of the inside of the reaction vessel 1, and two sets of rotating shafts 9 are provided inside the support plate 6 and the installation groove 7.

[0025] Reference Figure 1 , Figure 2 Inside the reactor 1, below the support plate 6, there is a movable groove 17, and one end of the movable groove 17 extends to the outside of the reactor 1. The movable groove 17 matches the sealing plate 5, and an elastic pad 18 is fixedly connected to the side of the sealing plate 5. The elastic pad 18 is usually made of rubber or silicone. When the rubber or silicone is squeezed and deformed, it can fill the gap of the sealing plate 5 well, ensuring the sealing performance. The elastic pad 18 is installed on the outside of the reactor 1 through a threaded knob 19.

[0026] In specific implementation, a sealed magnetic coupling stirring device, when undergoing maintenance, first manually unscrew bolt 2 to remove the protective cover 3 from the top of the reactor 1. Then, turn the threaded knob 19 to remove the sealing plate 5 and the elastic pad 18 from the movable groove 17. This facilitates cleaning and maintenance of the reactor 1's interior and allows for flexible replacement of the stirring blades 28 on the outer side of the rotating shaft 9, enhancing the device's adaptability and flexibility. After cleaning, maintenance, and replacement, align the protective cover 3 with the top of the reactor 1. First, tighten bolt 2 to install the protective cover 3. Then, insert the sealing plate 5 into the movable groove 17 and tighten the threaded knob 19 to fix it. Since the side end of the sealing plate 5 is fixedly connected to the elastic pad 18, the elastic pad 18 has an elastic function. During the rotation and squeezing process of the threaded knob 19, the elastic pad 18 is deformed by pressure, so that the elastic pad 18 can effectively fit against the outside of the reactor 1, thereby effectively filling the connection gap. Through the above operations, the quick-release connection structure makes maintenance and replacement more convenient, and at the same time, it further ensures the sealing performance. Example

[0027] Reference Figure 3 , Figure 4 This embodiment is an optimization based on the first embodiment. A stirring mechanism is provided on the outside of the rotating shaft 9. The stirring mechanism includes an inner magnetic rotor 10 and an outer magnetic rotor 11. The outer magnetic rotor 11 is provided above the inside of the limiting ring 4, and the corresponding inner magnetic rotor 10 is provided below the inside of the limiting ring 4. The inner magnetic rotor 10 and the outer magnetic rotor 11 attract each other through magnetic force and maintain synchronous rotation, driving the rotating shaft 9 to stir the inside of the reaction vessel 1. Both the inner magnetic rotor 10 and the outer magnetic rotor 11 are made of high-performance permanent magnet materials, which can form a strong magnetic field.

[0028] Reference Figure 2 The stirring mechanism also includes a driving synchronous wheel 25, a driven synchronous wheel 26, a synchronous belt 27, and stirring blades 28. An inner magnetic rotor 10 is fixedly connected to the top of one end of the rotating shaft 9. The driving synchronous wheel 25 is located below the inner magnetic rotor 10 on the outside of the rotating shaft 9. The driven synchronous wheel 26 is fixedly connected to the outside of the other end of the rotating shaft 9. The driving synchronous wheel 25 and the driven synchronous wheel 26 are connected by a synchronous belt 27. Multiple sets of stirring blades 28 are arranged on the outside of the rotating shaft 9.

[0029] Reference Figure 3 , Figure 5Bearings 20 are installed inside the support plate 6 and the mounting groove 7, and the rotating shaft 9 is installed inside the bearings 20. A guide sleeve 21 is installed above the mounting groove 7 on the outside of the rotating shaft 9. The guide sleeve 21 has a limiting function for the rotating shaft 9. The limiting ring 4 will cooperate with the guide sleeve 21 in time to limit the deviation of the rotating shaft 9 at high speed, thereby ensuring the stability and accuracy of the rotating shaft 9 when rotating at high speed. In addition, a discharge pipe 22 is installed inside the lower part of the reaction vessel 1, and a knob valve 23 is installed on the outside of the discharge pipe 22. A support frame is installed at the bottom of the reaction vessel 1. 24. The other end of the limiting ring 4 is located inside the protective cover 3 and a feeding hopper 12 is installed on the side. A sliding groove 13 is provided inside the upper part of the feeding hopper 12. A matching sliding cover 14 is provided inside the sliding groove 13 for sliding connection. A reducer 15 is provided on the top of the limiting ring 4. The reducer 15 model can be CVVM1H-6130-EP-43. The output end of the reducer 15 is fixedly connected to the external magnetic rotor 11. The top of the reducer 15 is fixedly connected to the drive motor 16. The drive motor 16 model can be Y132S2-2.

[0030] In specific implementation, a sealed magnetic coupling stirring device, when stirring, firstly, manually slides the sliding cover 14, causing it to move along the inner wall of the slide groove 13, thereby opening the feed hopper 12 and placing the raw material to be stirred into the feed hopper 12. Then, slides the sliding cover 14 to close, ensuring the sealing of the feed hopper 12. Simultaneously, due to gravity, the raw material slides through the feed hopper 12 into the reactor 1. Next, the drive motor 16 is started. The drive motor 16 is equipped with a reducer 15 to drive the outer magnetic rotor 11 to rotate inside the limiting ring 4. When the outer magnetic rotor 11 rotates, the magnetic field generated by the outer magnetic rotor 11 penetrates the inner wall of the protective cover 3, attracting and driving the inner magnetic rotor 10 to rotate synchronously inside the limiting ring 4. Due to the interaction between the inner and outer magnetic rotors... There is no physical contact between them, thus further ensuring the sealing of the stirring device. Furthermore, since the bottom of the inner magnetic rotor 10 is fixedly connected to the rotating shaft 9, the rotating shaft 9 rotates with the inner magnetic rotor 10 inside the bearing 20. Since the outer side of the rotating shaft 9 is connected to the synchronous belt 27 through the active synchronous wheel 25 and the driven synchronous wheel 26, the two sets of rotating shafts 9 can rotate synchronously, thereby driving the stirring blades 28 to rotate inside the reactor 1 for stirring. Since the two sets of rotating shafts 9 are equipped with stirring blades 28 of different shapes and sizes, the stirring quality is further improved. After stirring is completed, the knob valve 23 is manually opened to discharge the stirred raw materials through the discharge pipe 22. Through the above operations, the stirring efficiency and mixing uniformity are improved, further ensuring the sealing of the reactor 1.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
